[00:01:00] <furrywolf> hrmm, I don't like how neither the voltage nor current LED is on in their pictures, but maybe that's just how it behaves with both knobs are at zero...
[00:01:20] <furrywolf> it has a 14 day warranty at least.
[00:01:52] <_methods> did you try dying the parts that were in there?
[00:02:16] <PetefromTn_> they were only in there maybe 20 minutes
[00:02:48] <_methods> damn
[00:03:27] <_methods> i'm not sure how easy it would be to slap together a current limiting power supply

[00:03:53] <XXCoder> http://bbs.homeshopmachinist.net/threads/2693-Anodizing-power-supply-suggestions
[00:04:03] <XXCoder> one of em suggests car battery recharger
[00:04:19] <furrywolf> _methods: they're not complicated, if you have experience with analog electronics.
[00:05:32] <XXCoder> furrywolf: is it possible to convert a computer powerbox into what he needs? current limiting power supply
[00:06:12] <furrywolf> XXCoder: no
[00:06:20] <XXCoder> guessed not
[00:06:22] <furrywolf> http://www.ebay.com/itm/Lambda-LK-343A-FM-Regulated-DC-Power-Supply-Module-Variable-Benchtop-Lab-0-36VDC-/301684515942 is older, but high quality.
[00:06:32] <XXCoder> too bad, can go to computer junk store and buy one cheap
[00:08:03] <furrywolf> computer supplies are switchers, and generally not suitable to current limiting... and even if they were, switchers are much harder to modify.
[00:08:08] <furrywolf> also, they're mostly all crap.
[00:08:23] <furrywolf> http://www.ebay.com/itm/Lambda-LK-343A-FM-Regulated-DC-Power-Supply-Module-Variable-Benchtop-Lab-0-36VDC-/261958674639 same model as above, but tested working
[00:08:42] <PetefromTn_> Okay just powered down and unplugged it for awhile
[00:08:57] <PetefromTn_> then I just turned it back on and it seems to be working again.
[00:09:06] <PetefromTn_> I tried to hook it back up
[00:09:13] <PetefromTn_> bubbles are coming out again nicely
[00:09:24] <PetefromTn_> I turned the current down to 1.3 instead of the 1.6
[00:09:26] <_methods> put a fan on it
[00:09:32] <furrywolf> voltage meter reading correctly?
[00:09:32] <Tom_itx> thermal shutdown?
[00:09:34] <PetefromTn_> I already had a fan on it
[00:09:35] <_methods> try to keep it cool probably has a thermal
[00:09:39] <Tom_itx> get a friggin ammeter
[00:09:48] <PetefromTn_> no cash man
[00:09:54] <Tom_itx> $5
[00:09:56] <Tom_itx> ebay
[00:10:09] <XXCoder> how to build current limiting power supply http://www.microsyl.com/index.php/2010/03/31/bench-power-supply-0-25v-0-5amp/
[00:10:12] <PetefromTn_> yeah I will order one I guess but that does not help me right now
[00:10:16] <XXCoder> looks like it cost more than buy off ebay
[00:10:18] <furrywolf> harbor freight, $0. :)
[00:10:27] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/12v_supply2.jpg
[00:10:35] <Tom_itx> wonder if that would work for a supply
[00:10:37] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/12v_supply3.jpg
[00:11:01] <furrywolf> XXCoder: I don't think pete is in the mood to learn analog electronics for his anodizing tank. :)
[00:11:07] <XXCoder> indeed
[00:11:11] <Tom_itx> not constant current i don't think
[00:12:27] <PetefromTn_> Okay just went back out and checked it
[00:12:29] -!- lerman has quit [Ping timeout: 252 seconds]
[00:12:46] <PetefromTn_> it increased amps to 1.8 for some reason and the volts were around 18.5?
[00:12:50] <XXCoder> fur one nice thing is that it can be bought parts a time, and finally built, and it looks quite nice when done
[00:12:52] <PetefromTn_> I backed it down to 1.5 amps
[00:13:11] <Tom_itx> cookin more cookies
[00:13:16] <_methods> put it in one of those coolers full of ice lol
[00:13:17] <archivist> an old Kepco psu would also have the ability
[00:13:17] <PetefromTn_> trying to
[00:13:19] <Tom_itx> don't burn this batch
[00:13:27] <furrywolf> XXCoder: again, I don't think pete wants to learn analog electronic design just to anodize parts.
[00:13:45] <PetefromTn_> I don't think I have burned anything need more power I think
[00:13:45] <XXCoder> furrywolf: I know that already. I wasnt commenting for pete. :P
[00:14:00] <Tom_itx> pretty sure you do

[00:14:23] <PetefromTn_> what need more power?
[00:14:23] <Tom_itx> get a dc arc welder
[00:14:31] <_methods> lol
[00:14:37] <_methods> that'll do it
[00:14:40] <PetefromTn_> Got a DC/AC tig welder
[00:14:48] <Tom_itx> you think i'm kiddin...
[00:14:55] <_methods> no it's a power supply
[00:14:57] <_methods> that will do it
[00:15:03] <Tom_itx> duty cycle would be too low on it
[00:15:15] <_methods> depends on the quality of the welder
[00:15:18] <furrywolf> http://www.ebay.com/itm/Electronic-Measurement-EMI-SCR-20-40-OV-DC-Power-Supply-0-20-V-0-40-/380896710923 20V 40A... old but good.
[00:15:30] <PetefromTn_> mine is an L-tec 350 amp unit
[00:15:33] <furrywolf> I don't know of a welder that will accurately regulate a 1A output.
[00:15:41] <Tom_itx> usually they're low V and high A
[00:15:47] <_methods> waht is the duty cycle listed on it
[00:16:01] <_methods> i've never heard of ltec
[00:16:06] <PetefromTn_> ok resetting timer now
[00:16:17] <PetefromTn_> its the same people as ESAB now
[00:16:34] <_methods> oh jesus
[00:16:36] <_methods> burn it
[00:16:46] <_methods> just kidding
[00:17:17] <furrywolf> oh well, since yours seems to be working, I'll stop looking for good deals on ebay... but if it fries, consider replacing it with a used non-chinese unit.
[00:17:37] <furrywolf> a 10A supply overheating at 2A is... very chinese.

[00:18:26] <XXCoder> if chinese hardware specs to something I belive to 10% of it
[00:18:27] <jdh> 10 chinese amps
[00:18:39] <XXCoder> so 10A spec means its rated to 1A
[00:18:43] <furrywolf> heh
[00:19:00] -!- maximilian_h has quit [Ping timeout: 264 seconds]
[00:19:02] <XXCoder> if it has 1 mm precision I belive 1 cm precision :P

[00:19:47] <furrywolf> yeah, I like some of the tolerances claimed on chinese machines...
[00:19:59] <furrywolf> .001mm accuracy!
[00:20:18] <XXCoder> yeah I think I would apply 1% on that case
[00:20:21] <XXCoder> aka .1 mm
[00:21:04] <furrywolf> these are the same machines that make chinese stuff you buy where parts are a quarter inch away from fitting together. :)
[00:21:28] <XXCoder> my machine precision is good enough for me
[00:21:44] <XXCoder> I need only .003 accuracy or so
[00:21:50] <XXCoder> .003" specifically
[00:22:15] <PetefromTn_> damn it clicked off again
[00:22:28] <XXCoder> check for hot spots on it?
[00:22:29] <PetefromTn_> It does not seem to like anything north of 1 amp or so
[00:22:37] <PetefromTn_> Oh it is plenty hot LOL
[00:22:53] <furrywolf> it shouldn't be getting that hot at 1A. it may have something else wrong with it.
[00:23:00] <PetefromTn_> I am sure
[00:23:08] <PetefromTn_> or I am completely not using it correctly
[00:23:27] <furrywolf> there should be no method of using it that results in it failing. :)
[00:23:36] <PetefromTn_> when it turned back on the bubbles were going good again and the current was set to 1.5 amps
[00:23:44] <furrywolf> operating at high currents into a short tends to annoy them, but you said you were at >12V.
[00:23:55] <furrywolf> and low current.
[00:24:05] <XXCoder> PetefromTn_: does it have fans and is fana working?
[00:24:20] <PetefromTn_> it seems to show 14-15v and like I said no more than 1.6 amps
[00:24:27] <PetefromTn_> before it shuts down
[00:24:38] <PetefromTn_> when I kept it at 1 amp before it worked for hours
[00:24:52] <PetefromTn_> I am wondering if it is actually 1 amp and not more than that
[00:25:03] <PetefromTn_> perhaps the readout is not working correctly
[00:25:15] <Tom_itx> i can tell you how to find out :)
[00:25:17] <PetefromTn_> the bubbles and heat generated to the wires sure seems like a lot
[00:25:23] <PetefromTn_> yeah I know thanks tom
[00:25:36] <PetefromTn_> I actually used to have a meter that measured amps
[00:25:41] <PetefromTn_> but I loaned it out
[00:25:43] <furrywolf> that the wires are getting hot is a little odd.
[00:25:45] <PetefromTn_> and now it does not work at all
[00:25:53] <furrywolf> you could make your own current shunt and use a voltmeter.
[00:25:57] <PetefromTn_> when it is cooking good the wires were quite hot
[00:26:08] <Tom_itx> thermal shutdown
[00:26:15] <PetefromTn_> lots of bubbles from the cathodes
[00:26:30] <PetefromTn_> like sheets of bubbles you can see it in that last video I posted
[00:26:30] <archivist> I dont expect 1.6 amps to get wires hot
[00:26:32] <furrywolf> 1.6A shouldn't make anything but the thinnest wire hot.
[00:26:52] <PetefromTn_> the wires that hook to the unit via the alligator clips are pretty small
[00:26:59] <PetefromTn_> but it is what it came with
[00:27:09] <Tom_itx> get some bigger wire
[00:27:15] <PetefromTn_> I would not think they would sell it with that wire if it were not enough for the max capacity of the unit?
[00:27:24] <furrywolf> PetefromTn_: here's a random test for you... get your voltmeter out, and measure the voltage on the wires that connect between the supply and the alligator clips. that is, with it running, sneak the probe into the connector at the supply, and measure to the aligator clip on the same wire.
[00:27:25] <XXCoder> maybe shit quality wites
[00:27:26] <Tom_itx> pfft it's chinese
[00:27:27] <PetefromTn_> I can put bigger wires on it
[00:27:27] <XXCoder> wires
[00:27:55] <XXCoder> it may be getting hot trying to push 1.6A
[00:28:02] <XXCoder> because high wires resistance?
[00:28:07] <furrywolf> I want to see how much voltage you are dropping along each of the two wires.
[00:28:26] <PetefromTn_> lemme grab some larger wires and hook it up with that
[00:28:32] <furrywolf> XXCoder: instant current shunts. :)
[00:28:38] <Tom_itx> you need a volt meter across the 2 probes and an ammeter in series
[00:28:58] <PetefromTn_> the funny thing is the Titanium wire that came from Casewells is not real thick either and it gets pretty hot
[00:29:16] <furrywolf> I'm wondering if you didn't damage the current meter or internal current shunt... there's no way you're making any non-tiny wire hot at 1.6A.
[00:29:55] <furrywolf> you can run 1.5A through a usb cable and it doesn't get hot. :)
[00:30:10] <PetefromTn_> that is what I am wondering
[00:30:17] <PetefromTn_> these wires are pretty hot man
[00:30:19] -!- Loetmichel2 [Loetmichel2!~cylly@p54B11A24.dip0.t-ipconnect.de] has joined #linuxcnc
[00:30:24] <PetefromTn_> and the bubbles are substantial
[00:30:25] <furrywolf> how does the bubbling compare to the bubbling yesterday?
[00:30:37] <PetefromTn_> I watched a video of another guy using a damn car battery
[00:30:43] <furrywolf> do you have a harbor freight or radioshack nearby you can get a meter at?
[00:30:59] <PetefromTn_> and while there are more bubbles a car battery directly hooked to the parts has no regulation
[00:31:05] <PetefromTn_> so lots of amps going in
[00:31:15] <furrywolf> do you have any scraps of wire of known size? (romex, old extension cords, etc)
[00:31:17] <PetefromTn_> and it did not seem to be a helluva lot more
[00:31:27] <PetefromTn_> I have tons of wires around here
[00:31:36] -!- Loetmichel has quit [Ping timeout: 255 seconds]
[00:31:56] <PetefromTn_> lemme let it cool down again and I am going to hook it up without the small wires that it came with. I will use the same wires I used for the cathodes
[00:32:09] <furrywolf> do you have a meter that measures low voltages? (under 12V)
[00:32:26] <PetefromTn_> my meter has a setting for DC 200m
[00:32:42] <furrywolf> and, do you feel like a quick project that'll help you learn something about basic electronics and test the current of your supply at the same time?
[00:32:59] <PetefromTn_> I am wondering if the meter on the unit is reading in a factor of 10 or something
[00:33:31] <furrywolf> we can test that! :)
[00:33:48] <PetefromTn_> ya know I realize I come across as a moron electrically but at one time I was an Aviation Electronics tech in the USCG and worked on aircraft to the component level LOL
[00:34:09] <PetefromTn_> that was in another life it seems now
[00:34:13] <furrywolf> good, then building a current shunt will be easy for you.
[00:34:22] <PetefromTn_> how
[00:34:28] <XXCoder> PetefromTn_: yeah different periods of life
[00:34:28] <furrywolf> what type of wire do you have lying around? something between #18 and #14 will be best.
[00:34:38] <XXCoder> I used to be damn good on some stuff I cant do crap now
[00:34:47] <furrywolf> it needs to be a wire you _know_ the size of, as in printed on the side of it.
[00:34:56] <PetefromTn_> how much do I need?
[00:35:04] <Tom_itx> not alot
[00:35:07] <XXCoder> I used to understand matrix transforms (before college even) in order to make my project work
[00:35:08] <Tom_itx> it's gonna be a shunt
[00:35:22] <XXCoder> if you guys wanna see my souce code its still uploaded to git lol
[00:35:28] <PetefromTn_> how many feet?
[00:35:39] <Tom_itx> probably less than one
[00:35:44] <PetefromTn_> I have a huge box full of wires from the CNC build
[00:36:04] <_methods> PetefromTn_: if you go to mouser and search for a 0-10A power supply the cheapest one is like $400
[00:36:18] <furrywolf> depends on the size. let's just say 5ft for now, but grab a longer piece if you have one.
[00:36:23] <furrywolf> #18 would be ideal
[00:36:23] <PetefromTn_> _methods and this helps me how? ;)
[00:36:24] <_methods> so don't feel bad if you power supply isn't exactly doing what it's "rated" at
[00:36:43] <PetefromTn_> OK hang on let me see what I got
[00:36:45] <_methods> i'm just saying i doubt you'll get 10A at 30v with it
[00:36:56] <_methods> especially for hours on end
[00:37:09] <Tom_itx> you may get 10A OR 30v
[00:37:34] <_methods> exactly what Tom_itx said
[00:39:27] <PetefromTn_> OK I got a piece of marked 14 gauge 68" long
[00:39:48] <furrywolf> perfect
[00:39:51] <XXCoder> that reminds me, I need to go get 14 gauge white wire lol
[00:40:06] <XXCoder> to complete 4 color wires collection to build my cnc
[00:40:20] <furrywolf> now put it in series with the output of the supply. measure its length exactly (within a half inch) first, if that 68 was just an approximation.
[00:40:33] <archivist> http://chemandy.com/calculators/round-wire-resistance-calculator.htm
[00:41:17] <PetefromTn_> which side pos or neg
[00:41:27] <furrywolf> #14 wire is 2.525 milliohms / foot, or 0.014308333 ohms for 68 inches.
[00:41:28] <furrywolf> either one
[00:41:42] <Tom_itx> it's a closed loop, doesn't matter
[00:41:42] <furrywolf> all that matters is the current flows through it, and you know its exact size and length.
[00:41:48] -!- nofxx has quit [Remote host closed the connection]
[00:42:10] <PetefromTn_> if I hook it up to the terminal and the other end to the positive side I will get another wire for the negative side here
[00:42:11] <PetefromTn_> hang on
[00:42:34] <PetefromTn_> well like I said it is marked 14 gauge and I measured it with a tape measure to 68 inches long
[00:42:39] <furrywolf> also grab your meter with the 200mV scale
[00:42:39] <PetefromTn_> wait a sec
[00:42:57] <PetefromTn_> let me get this setup
[00:44:01] -!- lerman has quit [Ping timeout: 252 seconds]
[00:50:52] <PetefromTn_> okay removed the original small diameter wire/gator clip leads
[00:51:06] <XXCoder> probably 25gauge :P
[00:51:11] <XXCoder> kidding
[00:51:18] <PetefromTn_> replaced the negative wire with some of that 14 gauge wire and hooked it to the cathode wire
[00:51:49] <PetefromTn_> put a little crimp connector on the positive wire 68" long and screwed it under the positive terminal
[00:52:05] <PetefromTn_> used the same crimp connector on the negative terminal side too
[00:52:17] -!- asdfasd has quit [Ping timeout: 240 seconds]
[00:52:26] <PetefromTn_> now I am trying to find a damn inline crimp to hook it to the part/anode side
[00:52:29] <furrywolf> now, connect your meter to the piece of wire you measured. connect the meter _to the wire_ itself, not to the connections you made to it. the connections will make it not read correctly. strip off slightly more insulation if you have to, so you can get the meter probes directly on the wire. to make it easier, so you don't have to hold the probes, you can probably use the alligator clip wires that came with the supply in place of the probes, and clip th
[00:52:29] <PetefromTn_> hang on

[00:53:11] <PetefromTn_> lemme get the circuit closed here
[00:53:14] <PetefromTn_> hang on
[00:54:12] <furrywolf> k
[00:55:15] <PetefromTn_> okay I just put a wire nut on the wire end where it connects to my green wire that goes to the part/anode
[00:55:27] <PetefromTn_> I can probably stick the lead into the wire nut easily
[00:55:38] <PetefromTn_> just subtract a half inch from the length
[00:56:01] <PetefromTn_> so where do I measure from
[00:56:06] <furrywolf> you don't want it to be part of the same connection. strip back the wire further and connect the meter directly to the wire.
[00:56:19] <PetefromTn_> at both ends?
[00:56:23] <furrywolf> yes
[00:56:32] <PetefromTn_> Okay then what
[00:56:42] <furrywolf> just take a little chunk out of the side with a knife
[00:56:52] <PetefromTn_> I will
[00:56:57] <furrywolf> then connect your meter to both ends of the wire. :)
[00:57:06] <PetefromTn_> put the meter in 200m mode and go across the wire.
[00:57:17] <furrywolf> use the alligator clips that came with your power supply to connect the meter, so you don't need to hold the probes.
[00:57:32] <furrywolf> assuming both your benchtop supply and your meter use banana jacks, they should just plug into the meter.
[00:57:47] <PetefromTn_> I will turn on the power supply and set it for 1 amp I guess
[00:58:04] <furrywolf> yep, and see what the meter reads.
[00:58:09] <PetefromTn_> the wires to the power supply it came with have hoop/ring terminals
[00:58:17] <furrywolf> ah, never mind then.
[00:58:19] <PetefromTn_> so that will not work
[00:58:22] <PetefromTn_> standby
[00:58:25] <PetefromTn_> lemme test it
[01:01:28] <PetefromTn_> meter reads 74.0 take away an inch due to cutting and crimping
[01:02:42] <furrywolf> 2.525 milliohms / foot * 67 inches is 0.014097917 ohms. 74.0 millivolts / 0.014097917 ohms is.... 5.2490024 amps.
[01:02:58] <PetefromTn_> meter is reading 1 amp currently
[01:03:09] <PetefromTn_> I figured that was the case it is not reading right
[01:03:58] <furrywolf> now, try this. make a second nick in the side of the wire 47.5 inches from one of your other nicks, and measure there. should make the meter read about 52.4.
[01:04:22] <furrywolf> 47.5 inches will give you a nice round .01 ohms, so all you have to do is move the decimal point, no math.
[01:05:06] <PetefromTn_> wierd
[01:05:28] <PetefromTn_> just checked it again after making sure the supply was set to 1 amp
[01:05:28] <XXCoder> 5a?
[01:05:39] <PetefromTn_> got 33.3 on the meter
[01:06:56] <furrywolf> hrmm. there could well be components in common between both the meter reading and the current regulation. if those components were bad, it could be randomizing the output current while displaying the same thing on the meter.
[01:07:52] <furrywolf> find a way to attach the meter probes to the wire 47.5 inches apart, such as using the alligator clips, without using the other end of the leads at all, just to hold your probes in place for you.
[01:08:05] <PetefromTn_> so 33.3 is about 2.5 amps or so
[01:08:31] <furrywolf> yep
[01:08:57] <furrywolf> but, as I said, if you measure between two nicks on the wire 47.5 inches apart, you'll get a direct reading with no math needed.

[01:10:14] <furrywolf> SpeedEvil: for these purposes, the temperature coefficient of the copper is utterly irrelevant. lol
[01:10:30] <furrywolf> we're talking a fraction of a percent, for a meter that might be off over a factor of 5.
[01:11:12] <PetefromTn_> shit
[01:11:19] <PetefromTn_> it thermal'd out again
[01:12:06] <furrywolf> measure out your nicks and attach probes while it cools down. :)
[01:12:07] <PetefromTn_> so I saw 74.4 the first time then 33.3 the next time.
[01:12:29] <PetefromTn_> sound to me like the unit was actually working but the meters are totally off on it
[01:12:54] <PetefromTn_> I know the VM was optimistic by about a volt or so
[01:13:08] <PetefromTn_> the one on the power supply that is
[01:13:16] <PetefromTn_> This is maddening I swear
[01:13:37] <PetefromTn_> So assuming it does work again
[01:13:49] <PetefromTn_> I will adjust to say a half an amp this time
[01:13:52] <furrywolf> yes, which is why I'm suggesting a way to hook the meter probes to the wire without needing to hold them, and making it read a direct indication, so you can use your multimeter to set the current rather than the power supply's meter.
[01:13:54] <PetefromTn_> and measure
[01:14:31] <PetefromTn_> okay will try that here while it decides if it will work again
[01:14:36] <furrywolf> no. connect the probes to two nicks on the wire 47.5" apart, then adjust the current knob until your multimeter reads 10.0, which will be 1A.
[01:14:47] <PetefromTn_> interesting that it actually saw 5.6 amps tho
[01:15:13] <PetefromTn_> okay
[01:15:22] <furrywolf> and, just to check, you are measuring directly to the wire you added, not to the connections you made on either end of it, right? if you measure to the connections, you'll get bunk numbers. :)
[01:15:48] <PetefromTn_> nope cut the shielding on the wire just behind the connections at both ends

[01:27:02] <PetefromTn_> okay so I SHOULD be putting 2.1 amps into these two parts so is it safe to assume that 20.0 on the meter is what I need?
[01:27:16] <renesis> jt-aleska: crazy
[01:27:30] <furrywolf> so, assuming that was indeed #14 wire and your 200mV scale is accurate, that's 1A.

[01:31:49] <PetefromTn_> Okay just tweaked it to 20.1 for the 2.1 amps
[01:31:56] <renesis> damn i think it went up =(
[01:32:00] <PetefromTn_> it seems to respond very well
[01:32:09] <PetefromTn_> to inputs at the power supply controls
[01:32:20] <PetefromTn_> the fine adjustment is very good
[01:32:34] <PetefromTn_> right now the meter is showing .9 amps on the PPS
[01:32:44] <PetefromTn_> but the current meter we setup again is at 20.1
[01:33:13] <PetefromTn_> voltage is showing 10.9v on the PPS but I don't want to disconnect my meter to check what it actually is.
[01:33:22] <PetefromTn_> SO if this is all correct
[01:33:59] <PetefromTn_> that means that when I was anodizing this part last time for 120 minutes at 1 amp according to the power supply meter it was actually getting like 2.6 amps or so
[01:34:15] <PetefromTn_> which is way more than it was supposed to be getting
[01:34:19] <renesis> the panel meter is that far off?
[01:34:25] <PetefromTn_> apparently
[01:34:37] <PetefromTn_> I am gonna make another short video
[01:34:40] <renesis> because the sense resistor is prob to close to your load resistance
[01:34:42] <renesis> that sucks
[01:35:44] <furrywolf> I think the power supply broke earlier today when you did the short-circuit test.
[01:36:07] <renesis> that happens
[01:36:09] <furrywolf> does the bubbling at the cathodes today look like about double the 1A yesterday?
[01:36:30] -!- Servos4ever has quit [Ping timeout: 265 seconds]
[01:36:36] <renesis> its not really supposed to, but if you dont zero out the voltage and rise up to get the current you want when shorted, sometimes they pop

[01:39:14] <CaptHindsight> +not
[01:39:19] <furrywolf> but, just to check since I didn't see an answer, the #14 wire is decent quality wire, and not speaker cable, right?
[01:39:34] <XXCoder> furrywolf: or just cheaper compoments. few years laptop fires was due to subuation of certain type of lathanium for other

[01:41:30] <furrywolf> it broke the second day of use.
[01:41:40] <furrywolf> it has nothing to do with extreme operating conditions, age, or repeated abuse.
[01:41:44] <PetefromTn_> well technically not sure it has actually broken
[01:41:53] <renesis> shorting out a lab supply is abuse
[01:41:57] <PetefromTn_> it seems like it actually just does not read right
[01:42:05] <furrywolf> a major function of it no longer functions. that's broken. make them send you a new one. :)
[01:42:07] <renesis> with the voltages set high

[01:42:43] <CaptHindsight> send it back for refund, get better supply next time
[01:42:51] <furrywolf> check it with a current-reading meter first. there's always the risk my current shunt is wrong for whatever reason. I could have done math wrong, the wire could be undersized, your 200mv meter could be off, etc.

[01:51:01] <renesis> i trust these guys
[01:51:21] <furrywolf> PetefromTn_: next time you're out, get a meter with a working current scale, and check the accuracy with that.
[01:51:30] <sector_0> renesis, what about using something like a conduit strap?
[01:51:49] <furrywolf> or buy a fuse for that meter. :)
[01:51:56] <renesis> whats the bushing for?
[01:52:33] <renesis> i wouldnt trust a zip tie or strap without some sort of adhesive to keep it from moving
[01:53:33] <renesis> and its gotta be something hard like hot glue or epoxy
[01:53:53] <furrywolf> I see a 10A scale on the meter... usually there's an internal fuse that blows when it's overloaded. it's usually an odd size, and usually only available at electronics stores.
[01:53:59] <sector_0> renesis, the zip tie/strap is going to secure the linear rail bushing to the carriage
[01:54:05] <furrywolf> also, yay, I'm mentioned in a youtube video. :)
[01:54:10] <furrywolf> but it should be 21.0, not 20.1
[01:54:17] Tom_shop is now known as Tom_itx
[01:54:39] <furrywolf> (of course, with the accuracy of a home-made shunt like that, if you're within 15%...)
[01:55:09] <PetefromTn_> Oh okay 21.0
[01:55:14] <PetefromTn_> I will tweak it
[01:55:15] <XXCoder> in least he now reasonable know whats going on
[01:55:18] <renesis> i wouldnt both replacing the current meter fuse, just buy a precision sense resistor and use the DMM across it
[01:55:21] <PetefromTn_> does everything else look right?
[01:55:23] <XXCoder> so it was using way too much current?
[01:55:45] <furrywolf> yep
[01:55:47] <renesis> wait youre using wire as a sense resistor?
[01:55:59] <renesis> balls
[01:56:39] <Tom_itx> probably closer than his meter was
[01:56:45] <furrywolf> renesis: as it turns out, most people don't happen to have a collection of precision current shunts and sense resistors.
[01:57:28] <malcom2073> I'm just going to point out, that this is the kind of hacky shit ya'll make fun of reprap for

[01:57:31] <malcom2073> :P
[01:58:03] <renesis> repraps wobble, i dont even thing you should bring it up in a machine tool chan
[01:58:08] <furrywolf> but, as I said, check it with a proper meter... the shunt could be wrong. wire varries, and cheap meters often have cheap millivolt scales. I could also have made a math or research error. but, with the power supply hitting thermal shutdown, and the original wires getting toasty hot, I suspect it's right.
[01:58:15] <renesis> youre just asking for hate
[01:59:34] <PetefromTn_> malcom2073 Yeah I know it is hacky as hell
[01:59:41] <malcom2073> Seems to work though yeah? :P
[01:59:50] <PetefromTn_> well at least for the time being
[01:59:55] <PetefromTn_> the parts are cooking
[01:59:56] <renesis> do you have a frys?
[02:00:13] <renesis> or radio shack?
[02:00:34] <XXCoder> I usually call raio shack radio hack
[02:00:36] <PetefromTn_> I will say that one of the parts has sort of stopped bubbling and the other continues to cook
[02:00:37] <renesis> props if you actually have a real electronics shop within driving distance
[02:00:38] <PetefromTn_> not sure why
[02:00:52] <furrywolf> check for a loose wire to it
[02:01:16] <PetefromTn_> I THINK that the part that stopped is the one I have done twice now and it is possible that it is already anodized fully?
[02:01:18] <renesis> xxcoder: yeah i dont like being in there, but its saved my ass a ton of time at work for cables and adapters, jacks, connectors
[02:01:44] <PetefromTn_> or the TI wire I jammed into the tapped hole has lost contact
[02:01:48] <renesis> frys is much better, frys has like a whole aisle of pomona cables and test accessories
[02:01:56] <PetefromTn_> but I think that the wire gets all black when that happens
[02:02:03] <PetefromTn_> and it is not really black at all
[02:02:11] <XXCoder> frys is awesome indeed
[02:02:19] <XXCoder> and 45 minutes away for me
[02:02:26] <PetefromTn_> Today has NOT gone the way I had hoped it would
[02:02:37] <XXCoder> which isnt too bad now since I fixed my van and mpg has gone way up.
[02:02:41] <PetefromTn_> and I am STILL not sure about the dyeing stage
[02:02:53] <furrywolf> the wire won't do anything because the current can still flow through the other part
[02:02:56] <PetefromTn_> I just bought another van heh
[02:02:59] <furrywolf> has your voltage gone up?
[02:03:19] <PetefromTn_> not according to the chinese meter on the display
[02:03:53] <renesis> do you have any resistors to check the meter with?
[02:04:07] <PetefromTn_> ?
[02:04:23] <PetefromTn_> not my hand meter the meter on the power supply
[02:04:38] <PetefromTn_> it seems to be off by at least a volt and a half
[02:04:40] <renesis> right im saying to check either
[02:04:50] <furrywolf> if you had a resistor of a known value, like a 1 ohm resistor, you could calibrate both meters... but I'm figuring you probably do not.
[02:04:55] <renesis> heh, maybe someone fucked with the trim pots on the meters
[02:04:58] <PetefromTn_> I have some resistors somewhere around here
[02:05:18] <furrywolf> will be big power resistors, not little pcb ones
[02:05:21] <renesis> you prob want something low ohms, high watt
[02:05:35] <renesis> well if he has lots of little pcb ones, he can make a power resistor
[02:05:44] <PetefromTn_> yeah these are board type resistors
[02:05:56] <renesis> and get the resistance lower to maybe use as a sense resistor
[02:06:18] <PetefromTn_> jeez man I bought a power supply so I did not have to screw around with this type of crap LOL
[02:06:24] <renesis> if you have lots that are under 100R, you can prob make something
[02:06:54] <renesis> yeah but you bought random ebay supply, which is gambling at best
[02:07:00] <PetefromTn_> should have bought the one Captain recommended but it was like $275.00
[02:07:31] <renesis> or buy from a site that sells decent test gear along side the cheap shit, and has their name on it
[02:07:51] <furrywolf> I usually buy used american instead of new chinese when I can.

[02:09:52] <PetefromTn_> those all look like the same chinese stuff to me
[02:09:59] <XXCoder> I remember this advert banner "MADE IN USA!"... in back it says "Made in China"
[02:10:03] <renesis> right but these are companies you can call on the phone
[02:10:09] <renesis> that sell to engineering labs
[02:10:35] <renesis> Made in the USA = Cut Mad Corners to Stay Competitive
[02:10:49] <XXCoder> when I told someone that has that same banner on back of car this
[02:11:01] <XXCoder> he didnt belive me till I showed the tiny print in back at store
[02:11:31] <furrywolf> I'll put my Lambda supplies against chinese supplies any day. :)
[02:11:35] * furrywolf doesn't think they cut many corners
[02:11:52] <XXCoder> even cut corners has its corners cut off
[02:11:56] <renesis> how old is it
[02:11:58] <XXCoder> till there is no corners left
[02:12:07] <furrywolf> one's probably 20 years the other 30...
[02:12:13] <furrywolf> both work like the day they were made.
[02:12:22] <renesis> made in america 15 years ago isnt the same as made in america 2015
[02:13:05] <furrywolf> I mounted my rack-mount one under my workbench... just found some aluminum channel extrusion the right height, screwed it to the bottom of the workbench, and slid it in.
[02:13:21] <renesis> kinky
[02:14:20] <XXCoder> renesis: agreed. noit even chinese 2005 is same as chinese 2015. my lawn chair lasted long time, and currents ones are so weak
[02:14:36] <renesis> made in china is about QA
[02:14:46] <renesis> so its usually still about the company youre buying from
[02:14:46] <XXCoder> 10 years later lawn chair would catch on fire in sun and fall over by stress from being stared upon.
[02:15:15] <renesis> it could be all the same parts, just differences in assembly, and the reputable company will sell QA passing product
[02:15:28] <renesis> and the factory will just sell the QA rejects to someone else
[02:15:50] <renesis> the BOM is probably the same in a lot of cases
[02:16:25] -!- sumpfralle has quit [Ping timeout: 246 seconds]
[02:16:40] <renesis> if youre doing it right, fake parts should matter as much as people think, because the fake parts would have to pass the same QA testing
[02:16:50] <renesis> shouldn't
[02:17:06] <furrywolf> ... china has QA?
[02:17:16] <renesis> you dont know how this works, do you?
[02:17:55] <_methods> heheh
[02:18:00] <renesis> aamerican companies will use chinese contract manufacturers, and the contract should include QA standards
[02:18:50] <renesis> what happens a lot if american companies will setup chinese offices, with american and/or foreign engineers, and babysit QA, sourcing, process
[02:18:57] * furrywolf is so glad that including something in a contract will mean chinese companies will follow it perfectly with absolutely no corner-cutting, fake paperwork, or bribery of inspectors.
[02:19:14] <malcom2073> furrywolf: They will follow it perfectly, however the devil is in the details :P
[02:19:26] <renesis> the reason that happened is because engineers living here got sick of going over there all the fucking time

[02:19:42] <renesis> furrywolf: they will when youre standing there
[02:19:55] <CaptHindsight> QA is the big thing
[02:19:58] <renesis> they will when you dont pay for product
[02:20:23] <furrywolf> know what happens every time you have a chinese company audit another chinese company? the audit company gets paid twice.
[02:20:36] <renesis> everything mass production is made in china, or some place else in asia, its like even south america and mexico is too expensive
[02:20:41] <renesis> but good things still exist
[02:20:59] -!- Tecan has quit [Quit: Live Long And Phosphor!]
[02:21:00] <renesis> this means good things come from china, its very simple math
[02:21:18] <renesis> the difference is design for manufacturing and QA
[02:21:38] <furrywolf> my laptop proudly claims to be made in japan with no chinese parts. :P
[02:21:49] <CaptHindsight> if you see a product on fleabay that has the same specs as other products at twice the price, what should you think about this?
[02:21:52] <PetefromTn_> Well I just checked that one part that does not seem to be anodizing. The wire seems to be good inside there
[02:22:04] <malcom2073> CaptHindsight: They must be more efficient at making it of course!
[02:22:05] <PetefromTn_> the other part is fuming and bubbling still tho
[02:22:07] <furrywolf> PetefromTn_: could be, as you said, that one has cooked longer and is done.
[02:22:13] <renesis> furrywolf: your anecdote doesnt change anything
[02:22:19] <PetefromTn_> maybe I burned the crap out of it too many times LOL
[02:22:28] <furrywolf> PetefromTn_: you could remove the bubbling part and see what the voltage is with just that part
[02:22:29] <renesis> they make what you design to your standard, for a price
[02:22:29] <XXCoder> PetefromTn_: maybe its done?
[02:22:36] <furrywolf> or, it could be they'll equalize, as the less-cooked one catches up to it.
[02:22:41] <_methods> ding fries are done
[02:22:42] <renesis> companies wont pay the price or they dont know better about QA yet
[02:22:42] <PetefromTn_> no idea
[02:23:00] <PetefromTn_> the voltmeter says 7.8 volts but I just don't trust it anymore
[02:23:17] <renesis> man i had hash browns this morning, too much volume for the surface area
[02:23:18] <PetefromTn_> funny thing is the cathodes are still bubbling away real good
[02:23:19] <furrywolf> I've been really unhappy with chinese products lately. seems they reached a quality peak a while ago and are now going rapidly downhill.
[02:23:31] <renesis> was like a 3" roll of hash browns
[02:23:34] <CaptHindsight> lots of products have final assembly in the USA and are labeled made in the USA, that have all the parts made in China
[02:23:35] <PetefromTn_> and the ammeter setup we made is still holding at 21.o
[02:23:46] <renesis> capthindsight: ya
[02:23:48] <furrywolf> most chinese things I get are horribly misadvertised and promptly fail.
[02:23:54] <XXCoder> furrywolf: it may be case that more experenced compoanies there is still pretty good on QA, but there is hordes of ripoffs
[02:24:15] <XXCoder> most chinese stuff I got was pretty good
[02:24:16] <furrywolf> CaptHindsight: california sued leatherman for having the mexican factory stamping USA into the forgings. :)
[02:24:22] <renesis> made in usa guitar will use the same hardware as chinese guitar, but they will charge 10x
[02:24:26] <renesis> literally 10x
[02:24:31] <CaptHindsight> in China I can find just about any popular product being copied right down to the color and texture
[02:25:01] <CaptHindsight> they are often made in the same factories after hours or they sell the QC rejects
[02:25:41] <CaptHindsight> there are inferior copies and also "product over runs" that fall off the trucks

[02:28:43] <PetefromTn_> I guess I saved $200.00 and lost my sanity
[02:29:06] <furrywolf> maybe you need to have CaptHindsight lowered down from the ceiling...
[02:29:35] <PetefromTn_> not sure what that means
[02:29:40] <_methods> i you just gotta git'r'done use your battery charger
[02:29:46] <_methods> s/i/if
[02:30:00] <PetefromTn_> probably just blow up the damn battery charger
[02:30:09] <_methods> you'll have to adjust your time based on constant voltage instead of constant current though
[02:30:12] <PetefromTn_> it's not a top of the line model
[02:31:06] <furrywolf> deus ex machina... god from the machine... originally from greek tragedies, where they'd lower a god down from the ceiling to magically solve everyone's problems.
[02:31:07] <_methods> hell if you aren't breaking shit you're not making shit
[02:31:57] <furrywolf> the machine being the crane that lowerd the actor onto the set
[02:32:08] <PetefromTn_> well I guess I didn't technically break anything...the supply is actually doing something
[02:32:33] <PetefromTn_> would like to get a successful part anodized here somehow
[02:32:56] <PetefromTn_> wonder how bad a car battery would work LOL
[02:33:08] <PetefromTn_> I got a couple of those here ;)
[02:33:09] <zeeshan> it would work great
[02:33:31] <zeeshan> in anodizing, do you need the current limited?
[02:33:35] <zeeshan> or voltage limited
[02:33:47] <PetefromTn_> https://www.youtube.com/watch?v=l4TAeCjVEhs
[02:33:53] <zeeshan> cause i think it was voltage limited
[02:33:57] <zeeshan> but its been a while
[02:34:07] <furrywolf> current
[02:34:13] <zeeshan> oh okay
[02:34:19] <zeeshan> then a car battery woulkdnt be the greatest
[02:34:24] <zeeshan> unless you put it through a pot or something
[02:34:26] <furrywolf> so you have to use the right size charger. :)
[02:36:23] <PetefromTn_> jeez man this Power supply is a real POS
[02:36:28] <PetefromTn_> just checked it
[02:36:42] <PetefromTn_> and the current is still steady as a rock at 21.0
[02:37:01] <PetefromTn_> but now the current meter on the display says .5 amps and the voltage reads 7.4
[02:37:15] <zeeshan> wtf =/
[02:37:23] <XXCoder> crazt
[02:37:25] <PetefromTn_> parts are BOTH cooking now tho so I must have fixed the connection on the other part when I pulled it out
[02:38:01] <CaptHindsight> zeeshan: both but a 12V battery is limited to 12V :)
[02:38:07] <PetefromTn_> even if furrywolf's impromptu ammeter is off slightly the fact is that current is flowing and it is very consistent in nature
[02:38:14] <CaptHindsight> so you can't burn through
[02:38:51] <zeeshan> i was trying to say constant current vs constant voltage supply..
[02:39:01] <CaptHindsight> his wire could serve as a current limit as well
[02:39:26] <furrywolf> lol
[02:39:27] <CaptHindsight> it's obviously not ideal but it works
[02:39:38] <furrywolf> wire is not a curremt limiting or fusing device. :)
[02:39:40] <PetefromTn_> do you think the fact that the VM is reading a consistent 21.0 mv that the part is getting what it needs Capt?
[02:40:05] <CaptHindsight> PetefromTn_: I haven't been following that part of the discussion
[02:40:11] <PetefromTn_> the anodes are bubbling real good as they did before
[02:40:29] <PetefromTn_> well apparently the display on the new power supply is not accurate whatsoever
[02:40:31] <furrywolf> CaptHindsight: short version: he made a shunt from 47.5 inches of #14 copper wire and is measuring the voltage across it.
[02:40:42] <CaptHindsight> I'm actually working with the occasional scroll back
[02:40:52] <PetefromTn_> Ok
[02:41:16] <PetefromTn_> I can't see how it could NOT be anodizing this way if there is current flowing as apparently there is
[02:41:42] <XXCoder> I guyess as long as its bubbling it is anodizing but dunno
[02:41:45] <PetefromTn_> according to furry's calculations we are putting out 2.1 amps into the two parts
[02:43:25] <PetefromTn_> actual voltage is unclear as I don't trust the power supplies meters
[02:43:44] <XXCoder> cant add another multimeter to check volt?
[02:43:46] <PetefromTn_> I am gonna see if I can dig up my old voltmeter and measure that while it is cooking
[02:44:02] <furrywolf> voltage might naturally drop as bath heats up
[02:44:07] <furrywolf> is bath warming?
[02:48:07] <PetefromTn_> Ok just checked it again.
[02:48:21] <PetefromTn_> current is still showing 21.0 mv
[02:48:38] <PetefromTn_> and I removed the meter and switched it to DC volts and got 10.6
[02:48:52] <PetefromTn_> that is acutally UP from the 7.6 I was getting earlier
[02:49:06] <PetefromTn_> I put the meter back to show current again
[02:49:36] -!- lerman has quit [Ping timeout: 250 seconds]
[02:49:39] <furrywolf> so the meter on the supply reads 7.4, but your multimeter reads 10.6?
[02:50:01] <PetefromTn_> current on the power supply is showing .9 amps which is what it showed initially when I adjusted the output to show 21.0mv
[02:50:06] <furrywolf> and your multimeter is not complaining about low battery, right? so BOTH meters on the supply are crap? lol
[02:50:31] <PetefromTn_> furrywolf no actually I checked it before and it was 7.6 or so and now it is 10.6
[02:50:51] <PetefromTn_> so I THINK that means the parts are indeed getting anodized because the voltage is actually increasing
[02:51:02] <furrywolf> that's good, I guess. means they're building up oxide.
[02:51:04] <PetefromTn_> no low battery
[02:51:10] <PetefromTn_> yeah I think so
[02:51:46] <PetefromTn_> both parts are bubbling and the cathodes are really bubbling good like they were before when the amps were apparenlty way high
[02:52:01] <PetefromTn_> the power supply does not feel too hot either
[02:52:08] <PetefromTn_> nor do the wires
[02:52:19] <PetefromTn_> maybe this setup will work after all
[02:52:35] <furrywolf> I just hope it doesn't turn out my shunt is wrong and the power supply is right. :)
[02:52:54] <XXCoder> fur doubtful as it apparenbtly was all over map
[02:52:58] <zeeshan> how long has it been anaodizing it?
[02:53:08] <XXCoder> last reading he said was 0.5A 7.5V something
[02:53:31] <PetefromTn_> well to be honest my timer says 1.04 hours
[02:53:45] <PetefromTn_> but I accidentally paused it one time when I put it in my pocket
[02:53:51] <PetefromTn_> so it is more than that
[02:54:06] <PetefromTn_> probably more like an hour and a half at least
[02:54:13] <PetefromTn_> I am using my smartphones timer
[02:54:31] <zeeshan> hope it works out
[02:54:34] <XXCoder> yeah
[02:54:35] <zeeshan> cant wait to see those sexys
[02:54:55] <PetefromTn_> did you see that car battery anodizing video?
[02:56:16] <PetefromTn_> https://www.youtube.com/watch?v=l4TAeCjVEhs at 1:06 you can see the bubbles coming off his SINGLE Cathode
[02:56:22] <PetefromTn_> it really is bubbling
[02:56:32] <PetefromTn_> and the cathode is just a round tube or something
[02:56:43] <PetefromTn_> my cathodes are TWO flat plates
[02:57:17] <PetefromTn_> and I would say that if you combined the bubbles coming off both of the plates at any one time it would be a touch less than he is showing coming off that single cathode
[02:57:38] <PetefromTn_> but if he is using a car battery I would presume he is outputting a LOT more than 2 amps

[03:02:55] <zeeshan> explain practical anodizing to me
[03:03:05] <zeeshan> basically you put it in an acid beath and pass electricity

[03:03:21] <zeeshan> then you put it in die..
[03:03:30] <PetefromTn_> actually it creates the aluminum oxide layer
[03:03:30] <zeeshan> now the aluminum oxide reforms w/ the dye
[03:03:39] <XXCoder> yeah
[03:03:48] <zeeshan> so how does it hold the dye after?
[03:04:03] <XXCoder> it gets inside pores
[03:04:08] <XXCoder> then seal it in done
[03:04:23] <furrywolf> you probably should be exhausting it through an activated charcoal filter or something
[03:04:32] <zeeshan> so if i took a regular aluminum part
[03:04:36] <zeeshan> and dipped it in dye
[03:04:38] <zeeshan> what would happen?
[03:04:44] <zeeshan> (cause it has aluminum oxide on it too)
[03:04:49] <CaptHindsight> it would get wet

[03:07:41] <XXCoder> do you know why bee beehive cells is hexagon?
[03:07:59] <XXCoder> zeeshan: its because they are trying to make circles but structure turns em into hexagon

[03:10:10] <PetefromTn_> however voltage has increased to 10.89v
[03:10:20] <XXCoder> whats V on hand meter
[03:10:27] <PetefromTn_> that is on hand meter
[03:10:36] <PetefromTn_> so it has indeed increased
[03:10:42] * furrywolf will kick self hard if it turns out the shunt is wrong and the power supply right, but thinks not, since the wires getting hot would imply a lot more current.

[03:15:03] <XXCoder> anyway its fine for now
[03:15:06] <CaptHindsight> zeeshan: http://addis.caltech.edu/research/Self-organized%20formation%20of%20hexagonal%20pore%20arrays%20in%20anodic%20alumina,%20Jessensky%20et%20al,%20Apply%20Phys%20Lett.pdf
[03:15:07] <greg__> I'm curious as to what's up with that PS. how far of are teh meters?
[03:15:41] <XXCoder> greg__: not only far off, but apparently drifting. last he said it was 0.5A lol
[03:15:54] <zeeshan> you made me skim through this
[03:15:58] <zeeshan> 40+ page paper
[03:16:04] <zeeshan> just to give me a real paper after
[03:16:05] <zeeshan> thank u.
[03:16:20] <zeeshan> basically that paper said
[03:16:27] <PetefromTn_> greg__ I just can't trust the readouts unfortunately
[03:16:31] <furrywolf> greg__: I think something in the meter circuit fried during the short-circuit test earlier.
[03:16:36] <PetefromTn_> but the power output seems very consistent
[03:16:42] <PetefromTn_> at least according to my meter
[03:16:44] <zeeshan> "the repulsive forces between neighbouring pores in the metal oxide interface promote the formation of hex ordered pore arrangements
[03:16:46] <PetefromTn_> hand meter
[03:16:50] <XXCoder> PetefromTn_: whats its current lies on amp and volt?
[03:17:03] <PetefromTn_> huh?
[03:17:11] <XXCoder> displayed amp and volt
[03:17:17] <XXCoder> not your hand meter
[03:17:19] <PetefromTn_> .9 amps
[03:17:26] <PetefromTn_> 11.7 volts
[03:17:38] <CaptHindsight> zeeshan: did you get to see all the pictures?
[03:17:44] <zeeshan> yes
[03:17:55] <zeeshan> the abstracted of your second paper sums it up pretty good
[03:17:56] <zeeshan> This effect is correlated with a voltage dependence of the volume expansion of the aluminum during oxidation and the current efficiency for oxide formation. The resulting mechanical stress at the metal/oxide interface is proposed to cause repulsive forces between the neighboring pores which promote the formation of ordered hexagonal pore arrays
[03:17:58] <PetefromTn_> the voltmeter is actually increasing with the hand meter just the numbers are off by a volt or so
[03:18:11] <greg__> hmm not a very good supply, the short circuit is normal operating condition
[03:18:26] <zeeshan> i think thats pretty damn interesting
[03:18:28] <CaptHindsight> zeeshan: sorry, i didn't have them in order for you
[03:18:35] <CaptHindsight> your majesty :)
[03:18:36] <zeeshan> CaptHindsight: haha i was just complaining
[03:18:36] <zeeshan> :)
[03:18:45] <zeeshan> CaptHindsight: so what if i blasted a part with aluminum oxide
[03:18:49] <XXCoder> zee is king? ah knew it
[03:18:52] <zeeshan> now it has pores -- granted not nano level
[03:18:58] <zeeshan> wouldn't the dye hold..
[03:19:03] <XXCoder> still need seal
[03:19:07] <PetefromTn_> CaptHindsight since my timer is off as I accidentally paused it
[03:19:12] <zeeshan> im just at the dye part..
[03:19:16] <CaptHindsight> zeeshan: the pores change size with the use of different acids
[03:19:20] <PetefromTn_> is there any other way I can know that the parts are finished?
[03:19:22] <zeeshan> CaptHindsight: yes
[03:19:29] <zeeshan> but im saying, if i used aluiminujm oxide sand blasting
[03:19:38] <zeeshan> could i get the dye to hold
[03:19:45] <zeeshan> dip it in dye, then seal
[03:19:47] -!- lerman has quit [Ping timeout: 256 seconds]
[03:19:49] <XXCoder> zeeshan: same it for your PHD
[03:19:50] <zeeshan> it wont look as pretty
[03:19:53] <XXCoder> *save
[03:19:57] <CaptHindsight> zeeshan: the natural oxide layer is very thin
[03:20:26] <zeeshan> i wanna try it
[03:20:30] <zeeshan> just to see what happens..
[03:20:35] -!- ve7it [ve7it!~LawrenceG@S01060014d19d0b68.pk.shawcable.net] has joined #linuxcnc
[03:20:35] <zeeshan> cause i blasted some aluminum parts
[03:20:38] <CaptHindsight> if you used a focused ion beam to blast pores yes they could hold them but if they are hydrated then they won't hold them
[03:20:43] <zeeshan> and just touching them with oily hands
[03:20:43] <XXCoder> zeeshan: I woul guess it need very fine dust
[03:20:44] <zeeshan> its game over..
[03:20:54] <zeeshan> cause you get oilly prints all over em
[03:20:55] <CaptHindsight> zeeshan: it won't seal
[03:21:05] <zeeshan> so the dye will just wash out
[03:21:21] <CaptHindsight> the last step hydrates the aluminum causing it to swell, that is what captures the dye
[03:21:40] <XXCoder> interesting
[03:21:51] <zeeshan> swell up?
[03:22:00] <zeeshan> what do you mean swell up
[03:22:05] <XXCoder> CaptHindsight: it never "recovers" from swell up?
[03:22:06] <CaptHindsight> solvent or aqueous dye will just wipe off, you'd need a binder to make it stick
[03:22:35] <furrywolf> there's a product that's both dye and a binder available at most hardware stores... it goes under the name "paint" :)
[03:22:42] <zeeshan> rofl
[03:22:46] <CaptHindsight> the aluminum oxide layer is also translucent so the color of the dye comes through
[03:22:49] <XXCoder> heh
[03:23:09] <XXCoder> CaptHindsight: yeah anodize is basically making colored sapphire "skin"
[03:23:19] <zeeshan> honestly, im just curious about the process
[03:23:23] <zeeshan> for me, i like powdercoating
[03:23:31] <zeeshan> dont have to deal with chemicals, and its stronger
[03:23:43] <zeeshan> like im not sure if you've guys worked with this type of fitting:
[03:23:54] <XXCoder> anodize has awesome colors though
[03:24:05] <zeeshan> http://www.reganrotaryracing.com/turbofit.jpg
[03:24:06] <CaptHindsight> zeeshan: nah. melts right off
[03:24:22] <zeeshan> those scratch so easily
[03:24:24] <XXCoder> zeeshan: https://www.youtube.com/watch?v=3ZhVOy-ytJY
[03:25:15] <CaptHindsight> http://aluminumsurface.blogspot.com/2009/04/why-sealing-process-is-so-important.html
[03:25:18] <furrywolf> I don't much care for the colored anodizing look... I used one aluminum fitting on my subaru, and I got black painted. :)
[03:25:29] <zeeshan> lol
[03:25:36] <XXCoder> I do want to try anodizing alum but dunno lol
[03:25:39] <zeeshan> dude you really gotta use aluminum wrenches for those fittings
[03:25:42] <zeeshan> or they scratch up
[03:25:43] <XXCoder> I just want to get to machining stage first!
[03:25:49] <furrywolf> zeeshan-lab: you know you can get those ugly fittings in black, right? :P
[03:25:50] <zeeshan> i just use regular wrench with some tape
[03:25:56] <zeeshan> yea mine are black mostly
[03:26:10] <furrywolf> heh, I do have an albr adjustable wrench...
[03:26:12] <furrywolf> (aluminum bronze)
[03:26:24] <PetefromTn_> I want to offer the anodized parts because that is what most of my customers want
[03:26:42] <PetefromTn_> powder coat adds a good bit of thickness to parts and in some situations that can be a problem
[03:27:03] <PetefromTn_> so does anodizing but it is much less pronounced
[03:27:08] <zeeshan> its so strong though
[03:27:12] <zeeshan> have you seen how strong pc is?
[03:27:47] <XXCoder> that video I just linked to is awesome!
[03:28:07] <PetefromTn_> they both have thier place
[03:28:12] <furrywolf> zeeshan-lab: http://fw.bushytails.net/Subaru%20PS%2002.jpg
[03:28:14] <PetefromTn_> their
[03:28:17] <zeeshan> https://www.youtube.com/watch?v=Fn8n2IrVyY4
[03:28:22] <zeeshan> go to like 3 min
[03:28:29] <zeeshan> these guys bend the damn metal
[03:28:36] <zeeshan> and the powdercoat doesnt crack
[03:28:53] <zeeshan> is that left fitting zinc plated?
[03:28:56] * zeeshan loves zinc plated fittings
[03:28:59] <furrywolf> yes
[03:29:01] <zeeshan> they are pretty
[03:29:12] <zeeshan> http://i.imgur.com/H5jA7IE.jpg
[03:29:17] <zeeshan> you can see the fuel lines
[03:29:23] <furrywolf> steel fitting plus steel braided line = pressure, aluminum plus nylon braided = return. :)
[03:29:25] <zeeshan> going from zinc plated to those black jic fittings
[03:29:46] <furrywolf> http://fw.bushytails.net/Subaru%20PS%2001.jpg you'll like that fitting too, then
[03:30:27] <zeeshan> i like
[03:30:29] <zeeshan> very nice
[03:30:33] <zeeshan> that fitting doesnt look cheap
[03:31:00] <zeeshan> is that -6 hose?
[03:31:03] <zeeshan> (to get an idea of scale
[03:31:08] <furrywolf> no, that was the most expensive one. I needed the extra length to clear the intake manifold. the long-90 is hard to find.
[03:31:09] <furrywolf> yep
[03:31:47] <zeeshan> sweet :D
[03:32:06] <CaptHindsight> zeeshan: powder coatings are just micronized polymers with a Tg over 100 C
[03:32:18] <zeeshan> yep
[03:32:20] <zeeshan> and they kick ass!
[03:32:25] <zeeshan> i have that stuff on my chassis
[03:32:28] <CaptHindsight> zeeshan: f-yeah
[03:32:31] <zeeshan> it still looks new
[03:32:33] <furrywolf> I need to flush the power steering system again... the gearbox I got had water in it, and I got most of it out with the first flush, but it still needs another one. my fluid is pink instead of red. and while I like pink, I don't like it in my atf. :P
[03:32:46] <XXCoder> lol
[03:33:02] <CaptHindsight> we should powder coat one of your cars
[03:33:06] <CaptHindsight> inside and out
[03:33:10] <zeeshan> $$$$$$
[03:33:14] <CaptHindsight> nah
[03:33:15] <PetefromTn_> not sure how I am going to determine when these are fully cooked now LOL
[03:33:16] <XXCoder> I love colors on this https://img1.etsystatic.com/000/0/5781966/il_fullxfull.307150899.jpg
[03:33:24] <furrywolf> PetefromTn_: when you hit 15V? :)
[03:33:25] <XXCoder> powder coat each part, including windows.
[03:33:36] <PetefromTn_> do you think so?
[03:33:45] <CaptHindsight> it's easy to make
[03:33:54] <XXCoder> PetefromTn_: how long do you think it went untimed?
[03:33:56] <furrywolf> dunno, I'm not the expert. *pokes CaptHindsight*
[03:34:09] <PetefromTn_> not really sure maybe a half hour or so
[03:34:10] <CaptHindsight> you just mill the polymers down to size
[03:34:32] <PetefromTn_> gonna check it again here BRB
[03:34:56] <CaptHindsight> zeeshan: you should make a memory powder coat
[03:35:04] <zeeshan> rofl
[03:35:06] <zeeshan> that'd be cool
[03:35:15] <CaptHindsight> spray, heat and when it cools it's back to powder again
[03:35:20] <zeeshan> ROFL
[03:35:23] <zeeshan> the troll powder
[03:35:44] <XXCoder> make water dissolvable powder coat
[03:35:44] <zeeshan> dude im thinking of changing the permanent shape to a penis
[03:35:49] <XXCoder> bake it in, it stays firm till rain
[03:35:53] <furrywolf> I still think you should make car body panels that will un-accident themselves when the car is put in an oven. :)
[03:36:01] <zeeshan> then changing the temporary shape to a heart
[03:36:04] <zeeshan> and giving it to my gf
[03:36:05] <CaptHindsight> XXCoder: thats doable
[03:36:05] <zeeshan> ROFL
[03:36:10] <furrywolf> lol
[03:36:15] <CaptHindsight> cellulose or PVA based
[03:36:18] <XXCoder> lol
[03:36:22] <furrywolf> zeeshan-lab: do it, do it! :P
[03:36:31] <CaptHindsight> comes off in the car wash
[03:36:55] <zeeshan> the smp doesnt have enough pull strength to reshape metal
[03:37:01] <XXCoder> though powder coating entire car (besides rubber parts and whatnot) sounds awesome
[03:37:06] <zeeshan> but my colleagues are using it on a polymer - shape memory polymer laminate
[03:37:14] <XXCoder> completely immune to corrison, assuming no straches and such
[03:37:21] <CaptHindsight> thinking about it, maybe sugar based
[03:37:24] <zeeshan> and theyve had success in the smp restoring the base polymer that was dented, back to its original shape
[03:37:27] <CaptHindsight> would be glossy
[03:37:41] <XXCoder> CaptHindsight: would be great for short term fun designs on car
[03:37:53] <XXCoder> spray it on, looks glossy then it fades in water
[03:38:15] <CaptHindsight> real candy coat
[03:38:20] <XXCoder> indeed
[03:38:43] <CaptHindsight> glossy latex would also work
[03:39:03] <CaptHindsight> with a loose structure
[03:39:11] <XXCoder> zeeshan: this looks like parts you was making lol http://www.southerncarparts.com/images/Camaro%20Parts/Camaro-Burnt-Orange-Aluminum-Racing-Pedals-Grid-Finish.jpg
[03:39:12] <furrywolf> on a related topic, that "temporary" white paint they sell for making For Sale vehicles? DOES NOT COME OFF EASILY.
[03:39:21] <zeeshan> those look nice
[03:39:28] <XXCoder> furrywolf: lol
[03:39:37] <CaptHindsight> how about thermite powder coat?
[03:39:40] <zeeshan> rofl
[03:39:44] <PetefromTn_> Okay just checked it again.... still sitting at 21.0mv, voltage increased to 11v
[03:39:48] <XXCoder> CaptHindsight: lol
[03:39:52] <zeeshan> PetefromTn_: you're getting success!!!!!!!!!
[03:40:02] <furrywolf> CaptHindsight: only if you're making an airship.
[03:40:05] <PetefromTn_> we'll see
[03:40:07] <zeeshan> doesnt you wish you had better eyes?
[03:40:11] <zeeshan> so you could see the atoms
[03:40:13] <XXCoder> oh the humanity!
[03:40:19] <zeeshan> you'd know whats going on :P
[03:40:42] <furrywolf> I don't think even superman has electron microscope vision...
[03:40:43] <PetefromTn_> it seems like the current output is VERY stable in the power supply so that is good
[03:41:01] <PetefromTn_> at least according to my home built ammeter ;
[03:41:03] <PetefromTn_> ;)
[03:41:15] <XXCoder> PetefromTn_: yeah just weirdly broken display
[03:41:20] <zeeshan> youre using a current shunt?
[03:41:21] <zeeshan> lol
[03:41:27] <XXCoder> maybe check some stuff if something burnt
[03:41:28] <zeeshan> nice
[03:41:40] <PetefromTn_> yeah it is what I had
[03:41:49] <zeeshan> ok its bed time
[03:41:49] <zeeshan> cu
[03:41:53] <zeeshan> post pics
[03:41:53] <PetefromTn_> cu
[03:41:56] <zeeshan> so i can see in the morning
[03:41:58] <zeeshan> i want success
[03:41:58] <zeeshan> !
[03:42:08] <PetefromTn_> don't hold your breath
[03:42:14] <zeeshan> youre gonna do it
[03:42:14] <furrywolf> zee going to bed at a reasonable hour? impossible!
[03:42:18] <zeeshan> just think about it PetefromTn_
[03:42:29] <zeeshan> you're growing hexagno crystals
[03:42:32] <zeeshan> with pores
[03:42:35] <zeeshan> what could go wrong :D
[03:42:42] <PetefromTn_> apparently quite a lot
[03:42:44] <zeeshan> furrywolf: yea im toast :P
[03:43:09] <XXCoder> hopefully not literally heh
[03:46:00] <furrywolf> on a sleeping-related topic, anyone own a rooftent? how do they work?
[03:46:19] <XXCoder> I only own the dome one
[03:46:28] <furrywolf> a rooftent?
[03:47:00] <XXCoder> http://www.rooftent.co.uk/images/hannibal/tourer-open-1lrg.JPG ?
[03:47:03] <XXCoder> never saw it before
[03:47:22] <furrywolf> yes
[03:47:27] <furrywolf> and I'll that that as a no. :)
[03:47:32] <XXCoder> yea lol
[03:48:05] <XXCoder> CaptHindsight: was it you who rebuilt cninese router and anodized it
[03:48:14] <XXCoder> I remember someone who did it, looked awesome.

[03:48:45] <XXCoder> that looks weird
[03:48:48] <furrywolf> they have a framework, and fold up into a little streamlined hard-sided pot.
[03:48:49] <furrywolf> pod
[03:49:00] <furrywolf> then you just flip them open and have a tent
[03:49:04] <XXCoder> if rooftent is rocking don't come knockin'

[03:50:43] <furrywolf> http://www.autohome-official.com/images/slides/maggiolina-air-top/03.jpg nice and aerodynamic
[03:51:37] <furrywolf> I'm thinking if I can't work, I might try taking an brief vacation... but since I can't hike, I'll be car camping... and since I can't drive my truck right now (my truck takes a fully functional back and legs to operate, and I have neither), it'd have to be in the car...
[03:51:46] <PetefromTn_> https://www.youtube.com/watch?v=mQmzxN15ga8
[03:52:14] <XXCoder> fur if I went camping I would just sleep in back of my van
[03:52:17] <XXCoder> pretty good room
[03:52:31] <furrywolf> I used to sleep in the back of my truck, but I can't drive it.
[03:52:56] <furrywolf> I have the proverbial "armstrong" steering, and no power brakes...
[03:53:08] <XXCoder> drat
[03:54:57] <furrywolf> http://www.autohome-official.com/en/video/airtop-roof-top-tent-tech-tv that model is even simpler, doesn't have to unfold
[03:55:13] <furrywolf> probably too long for a car roof, though. lol
[03:55:14] <XXCoder> furrywolf: I remember this easy to use tow camp
[03:55:25] <XXCoder> just rise roof and lock, pop out sides and there it is
[03:56:00] <XXCoder> friend of mine that was in very bad way lived in my home lot that way for couple months before she recovered and moved on
[03:56:05] <XXCoder> she got it for $100
[03:56:08] <PetefromTn_> CaptHindsight Hey man how long would you say I need to keep the parts submerged in the dye?
[03:56:22] <furrywolf> until they're done. :)
[03:57:15] <CaptHindsight> PetefromTn_: long enough to cover them, it happens pretty fast, it flows right in
[03:57:33] <XXCoder> I guess theres lower limit on time but no upper limit
[03:57:43] <XXCoder> once its done it just stays till youre ready
[03:57:51] <XXCoder> dunno tough
[04:01:18] <CaptHindsight> you can spray, brush, splash etc it on
[04:02:21] <furrywolf> http://www.gordigear.com/roof_tents/roof_tents.php?l=en watch the first 30 seconds of the first video. soooo easy to set up...
[04:04:20] <PetefromTn_> Okay
[04:04:24] <PetefromTn_> just pulled the parts out,
[04:04:35] <PetefromTn_> sprayed them down with DI water bottle
[04:04:56] <PetefromTn_> soaking them in a tray of clean DI water right now
[04:05:00] <CaptHindsight> let them dry
[04:05:10] <CaptHindsight> maybe even use a hair dryer
[04:05:11] <PetefromTn_> now I will pull them out and let em dry
[04:05:23] <PetefromTn_> Okay I have one here
[04:06:09] <CaptHindsight> the solvent dye won't mix with water, it will separate
[04:06:12] -!- jt-alyeska [jt-alyeska!~androirc@190.sub-174-236-79.myvzw.com] has joined #linuxcnc
[04:06:44] <CaptHindsight> that is another way to get color effects
[04:07:03] <CaptHindsight> mix the solvent dye with water bath
[04:07:23] <CaptHindsight> the solvent dye will float on top of the water until agitated
[04:07:47] <XXCoder> interesting https://www.youtube.com/watch?v=O0GQPHh3Szk
[04:07:49] <XXCoder> look at end
[04:07:53] <XXCoder> it seals pores
[04:08:01] <CaptHindsight> if you get a froth going it will leave color patterns of both the water and solvent dye
[04:09:16] <CaptHindsight> poor seals

[04:20:47] <furrywolf> wtf? the AUD is now >> USD? stupid economy.
[04:21:35] <PetefromTn_> Okay I just pulled the parts out of the anodizing tank
[04:21:59] <PetefromTn_> rinsed them off really really good with DI water and soaked them for maybe ten minutes in the water
[04:22:14] <PetefromTn_> then I dried them completely using a fan and a hair dryer
[04:22:28] <PetefromTn_> let them sit hanging in the fan breeze for another ten minutes or so
[04:22:37] <PetefromTn_> they looked really nice and good and dry
[04:22:45] <PetefromTn_> then I dipped them into the dye
[04:22:53] <PetefromTn_> let them sit in the dye for a couple minutes each
[04:23:03] <PetefromTn_> then hung them back up to air dry
[04:23:23] <PetefromTn_> got the sealer bath cooking and ready
[04:23:39] <PetefromTn_> once they are fully dry I will immerse them in the sealer bath for 15 minutes
[04:23:49] <XXCoder> cool
[04:23:49] <PetefromTn_> then we will see what we have here
[04:23:54] <XXCoder> hopefully it will look good.
[04:24:02] <PetefromTn_> yeah I know right
[04:24:06] <PetefromTn_> it sure would be damn nice
[04:24:27] <XXCoder> man I want my cnc router working NOW
[04:25:04] <XXCoder> evenually will need to buy ER11 holders so I can use vareity of tools
[04:25:24] <furrywolf> yay, the neighbors up the road are having yet another loud domestic dispute.
[04:25:46] <furrywolf> er...11? minimill?
[04:25:46] <XXCoder> get a LOUD repeator
[04:25:55] <XXCoder> return what they said to em
[04:26:06] <XXCoder> checking a sec
[04:27:06] <XXCoder> "Max Ourte-dia:25mm"
[04:27:08] <furrywolf> er11 is good to, what, 1/4"? heh
[04:27:14] <XXCoder> "Collect chunk diameter: 6mm"
[04:27:29] <furrywolf> yeah, 6mm is even smaller than 1/4". lol
[04:27:32] <furrywolf> (by a hair)
[04:27:38] <XXCoder> yea but same time my router is tiny and riciously fast spindle
[04:27:46] <XXCoder> 27000 rpm
[04:27:54] <furrywolf> ah
[04:27:56] <XXCoder> great for wood and some alum
[04:28:08] <furrywolf> I'm planning on collets up to 3/4" for my mill...
[04:28:14] -!- sumpfralle [sumpfralle!~lars@megumi.opennet-initiative.de] has joined #linuxcnc
[04:28:30] <XXCoder> in future, probably far future, I want to get cnc router with 4 feet by 8 feet workspace
[04:28:39] <XXCoder> so I can make stuff out of whole sheet
[04:29:25] -!- AR_ has quit [Ping timeout: 246 seconds]
[04:29:42] <furrywolf> I want to build a combined router/plasma table. just put a sheet of MDF over the slatted plasma bed and swap heads...
[04:29:44] <XXCoder> this spindle http://www.aliexpress.com/snapshot/6759651360.html?orderId=68075122285562
[04:29:55] <XXCoder> thats pretty great idea
[04:29:58] <XXCoder> save lot space
[04:30:16] <XXCoder> maybe make it has removable supports for that mdf bed
[04:30:26] <furrywolf> or hell, have both heads on, and just make sure you flip the right switch. :)
[04:30:32] <XXCoder> lol
[04:30:36] <XXCoder> torch the wood
[04:30:49] <furrywolf> have one on either side of the gantry, so it balances nicely.
[04:31:01] <XXCoder> less Y space though
[04:31:31] <XXCoder> know what would be brilliant? make it automically swap plasma/spindle
[04:31:40] <furrywolf> you're in 220V land?
[04:31:52] <XXCoder> furrywolf: nah but I alsobought an adoptor
[04:32:58] <furrywolf> http://www.rooftent.co.uk/images/hannibal/Rooftentopensequence1.gif
[04:33:28] <XXCoder> pretty strightforward
[04:34:35] <XXCoder> http://www.aliexpress.com/item/Step-Up-Voltage-Converter-Adapter-110V-US-to-220V-US-EU-Black/1910410399.html
[04:34:42] <XXCoder> it was pretty cheap so yeah
[04:35:11] <XXCoder> weirdly picture says eu/us to us
[04:35:20] <XXCoder> but rest of page saus us to eu/usa
[04:35:23] <furrywolf> that is not running that.
[04:35:24] <XXCoder> okkay lol
[04:36:09] <XXCoder> ?
[04:36:43] <furrywolf> you are not running a 500W spindle off a 40W adapter.
[04:37:14] <XXCoder> ah yea I see the problem now
[04:37:24] <XXCoder> hmm
[04:37:52] <furrywolf> you're about 450W short. :)
[04:38:11] <XXCoder> guess im out of router for couple months then
[04:38:21] <XXCoder> my budget is bit pinched for this month and next
[04:38:30] <furrywolf> or wire it to 240, or buy a proper size transformer.
[04:38:33] -!- sector_0 has quit [Quit: Leaving]
[04:38:45] <XXCoder> that or just modify router I do own here
[04:38:53] <XXCoder> problem is its bit hard to modify
[04:39:14] <furrywolf> it's easy to modify... just make an adapter on your router! oh, wait...
[04:39:33] <XXCoder> no, modify would take sawing off bits of router
[04:39:41] <XXCoder> parts that hit clamp
[04:40:06] <XXCoder> it has good range of rpm though, from 8k to 12k rpm
[04:40:50] <furrywolf> likely starts at 0 with an external speed control.
[04:41:15] <XXCoder> nah 8k is minium
[04:41:31] <furrywolf> how did you determine this?
[04:41:33] <XXCoder> well besides turn it off lol
[04:41:43] <XXCoder> it says so on box, 8k to 12k rpm
[04:41:49] <XXCoder> pretty nice bosch router
[04:41:55] <furrywolf> ok... which is why I said "with an external speed control"
[04:42:05] <furrywolf> as in "plugging it into another piece of hardware".
[04:42:08] <XXCoder> ok
[04:42:15] <XXCoder> wonder how pete is doing
[04:42:25] <XXCoder> brb a sec

[04:46:23] <PetefromTn_> LOL don't wait on me man... They are in the sealer bath right now
[04:46:45] <PetefromTn_> honestly when I put them in the bath a bunch of dye came off like it did before so I am kinda not too hopeful right now
[04:47:00] <PetefromTn_> will know in about ten minutes after the bath is done
[04:47:14] <PetefromTn_> I let them dry for a good long time to make sure the dye dried off completely
[04:47:27] <XXCoder> is sealant hot?
[04:47:33] <XXCoder> if I recall it needs to be hot
[04:47:35] <PetefromTn_> yeah 200 plus
[04:47:43] <XXCoder> no problem then i guess
[04:47:58] <PetefromTn_> it is boiling sometimes as my hot plate clicks on and off maintaining temp

[04:49:25] <XXCoder> maybe it will be fine
[04:49:33] <PetefromTn_> the only thing I can think of trying is two things
[04:49:43] <PetefromTn_> one to just try it with a damn car battery
[04:50:05] <furrywolf> " US $524.00 / piece " "Shipping:
[04:50:05] <furrywolf> US $718.94 / piece"
[04:50:06] <PetefromTn_> and two to try some rit dye after anodizing the part instead of the solvent dye and make a hot bath with DI water
[04:50:23] <furrywolf> ... "let's stick half the product cost in the shipping box so it shows up earlier in searches!"
[04:52:08] <furrywolf> PetefromTn_: some things to try might be more/fewer washing steps, longer "cooking" (leave it in all day!), different dye or dye concentration, umm...
[04:52:13] <PetefromTn_> my cathode plates sure look like they have been thru the ringer
[04:52:26] <PetefromTn_> they are really dark grey where they were in the acid
[04:52:52] <PetefromTn_> and the screws I used to secure the wires to them have corrosion all over them.
[04:52:54] <PetefromTn_> nasty shit
[04:53:07] <furrywolf> yep
[04:53:09] <furrywolf> keep fingers out.
[04:53:21] <XXCoder> furrywolf: http://imgbin.org/index.php?page=image&id=24709
[04:53:28] <PetefromTn_> I believe I washed and etched the parts adequately
[04:53:31] <XXCoder> you can see two parts
[04:53:45] <XXCoder> the smaller shaft is 43mm and would fit
[04:53:57] <PetefromTn_> and I rinsed the parts after the anodizing bath as well as sprayed them off with damn near a whole bottle of DI water
[04:55:28] <furrywolf> by shaft you mean the aluminum bearing housing?
[04:55:51] <XXCoder> the smaller part, between general housing and the chuck
[04:55:55] <furrywolf> I find letting the dye dry thickly on the surface to be a little odd...
[04:56:33] <furrywolf> how much longer to seal them? :)
[05:01:15] <PetefromTn_> Okay folks... another miserable failure
[05:01:43] <CaptHindsight> what happened this time?
[05:01:52] <PetefromTn_> the same thing
[05:02:00] <PetefromTn_> streaky grey parts
[05:02:02] <PetefromTn_> voids
[05:02:26] <PetefromTn_> looks like crap basically
[05:02:27] <CaptHindsight> same place or random other areas?
[05:02:48] <PetefromTn_> random for the most part
[05:03:04] <PetefromTn_> one of the parts seemed to take the dye better than the other..
[05:03:26] <PetefromTn_> I wiped them both down with acetone after I took them out of the sealer to get the excess dye off of them
[05:03:42] <PetefromTn_> lots of dye came off on the rag one one not so much on the other
[05:04:20] <PetefromTn_> I THINK the one that took it better was the one I have done three times now
[05:04:26] <CaptHindsight> did one part stay in the anodize tank longer than the other?
[05:04:30] <XXCoder> from what I learned from videos its usually acetone, lye to clean parts, then distalled water, the anodize opart, distalled, dip and wait in dye
[05:04:33] <PetefromTn_> no
[05:04:45] <XXCoder> take out, distalled water again, then hot water to seal
[05:05:41] <XXCoder> not too sure on lye part, only one vieo had that
[05:06:16] <furrywolf> got a picture?
[05:06:17] <CaptHindsight> who knows what you power supply is doing
[05:06:25] <CaptHindsight> I'd fix that first
[05:06:38] <CaptHindsight> you/your
[05:06:39] <furrywolf> or just leave it in all day
[05:06:45] <furrywolf> make sure it's done.
[05:07:06] <CaptHindsight> but in a pinch I'd try using a battery charger tomorrow
[05:07:50] <PetefromTn_> http://i.imgur.com/jxmK434.jpg http://i.imgur.com/qDtHiMk.jpg
[05:08:31] <CaptHindsight> very close
[05:08:39] <furrywolf> is your dye mixed with the right solvent at the right concentration?
[05:08:47] <PetefromTn_> close to what...quitting? ;)
[05:09:06] <PetefromTn_> the dye is as delivered
[05:09:25] <PetefromTn_> just shook it a little and poured it out of the bottle into my little trough
[05:09:54] <PetefromTn_> to be honest today has been one unfortunate thing after another
[05:10:34] <PetefromTn_> really disappointed with the results and disappointed I did not have the cash to buy a better power supply
[05:10:37] <furrywolf> the whole thick-layer-of-dye-needing-to-be-wiped-off thing seems weird... like either the dye needs to be thinned, or there's a rinse step between dye and seal rather than dry...
[05:10:57] <CaptHindsight> spots are usually contamination from one step to another
[05:11:14] <PetefromTn_> I don't see how I could have contaminated it
[05:11:33] <PetefromTn_> I cleaned and sprayed it really good between steps and even rinsed it in a bath
[05:11:43] <furrywolf> etch, put back in the anodizing tank, go to bed. take out tomorrow, after it's been cooking 8 hours. :)
[05:11:58] <PetefromTn_> I also never physically touched anything but the top of the TI wire hook where it attaches to the rack rail
[05:12:15] <furrywolf> did you use compressed air again?
[05:12:28] <PetefromTn_> furrywolf I would love to but I would be afraid this POS would burst into flames while I sleep and burn my house down
[05:12:45] <PetefromTn_> no I did not use compressed air this time
[05:12:45] <CaptHindsight> bbl
[05:12:54] <PetefromTn_> I used a blow dryer
[05:12:58] <PetefromTn_> Cya Capt
[05:13:04] <PetefromTn_> thanks for the assistance
[05:13:10] <furrywolf> hrmm, so not carryover from air compressor crankcase oil...
[05:13:16] <PetefromTn_> naah
[05:13:28] * furrywolf has had that happen with paint spray guns, and it's most annoying.
[05:14:03] <XXCoder> wanna know whats weird
[05:14:03] <PetefromTn_> I honestly have no idea what is wrong with this process
[05:14:13] <XXCoder> my router dont have controls for changing rpm
[05:14:17] <PetefromTn_> I have tried to follow all the online descriptions
[05:14:28] <furrywolf> try cooking for 4+ hours next time. also confirm with capt that the dye was supplied ready-to-use and not in need of thinning with solvent.
[05:14:36] <furrywolf> for now.. bbl. past wolfy bedtime.
[05:14:40] <PetefromTn_> I gotta throw in the towel here tonight
[05:14:55] <PetefromTn_> maybe I will try again tomorrow but I dunno at this point

[07:27:19] <archivist> what is a C10 board
[07:30:31] <archivist> often dont need full models when creating something as a one off
[07:32:27] <pcb_maker> this is the brakeout board
[07:33:09] <pcb_maker> I can do it as a box.. but i like to make stuff realistic
[07:33:13] <archivist> never needed to model the breakout, just wire it
[07:33:47] <pcb_maker> I'm desigen the new panel
[07:34:24] <pcb_maker> I want it to be like a pro.
[07:34:41] <archivist> place real items on a panel, drill, wire
[07:34:50] <pcb_maker> NO!
[07:35:13] <archivist> its....quicker
[07:35:33] <archivist> and be as pretty
[07:35:37] -!- lerman has quit [Ping timeout: 246 seconds]
[07:35:42] <pcb_maker> this is not the right way to make a panel for 5 drivers and 36 cable glands..
[07:36:27] <pcb_maker> and about 20 temp sensors..
[07:36:57] <pcb_maker> 4 voltages
[07:37:12] <pcb_maker> 5 12 72 110
[07:37:18] <archivist> just placed is how this one started out http://www.collection.archivist.info/archive/DJCPD/PD/2008/2008_01_05_cnc_build_start/P1050048.JPG
[07:38:03] <pcb_maker> very nice
[07:38:18] <pcb_maker> my is about 10 times bigger
[07:38:20] <archivist> just rebuilding it at the moment as it ended up at 5 axis
[07:39:14] <pcb_maker> now i have 4 motors but just 3 connect to tha machine
[07:39:27] <pcb_maker> and 4 drivers
[07:39:48] <pcb_maker> but place for 5 drivers with heat sinks for 5 drivers
[07:40:57] <pcb_maker> now I'm working on the panels for the brakeout bord so I can mout tham also on the din rail..
[07:42:46] <archivist> that may be better off the din so the socket can be through the case
[07:47:30] <pcb_maker> what so you mean by "the socket can be through the case"
[07:47:49] <archivist> the parallel port connector
[07:48:21] <pcb_maker> it is an option...
[07:48:33] <pcb_maker> but i dint know how much i like it.
[07:49:22] <archivist> that is why that is off my new version, it is ready to be fixed into the case after I make the holes
[07:51:03] <pcb_maker> I'm going to take M>F connector ans make it on the plate and than to thake LPT cable from it to the board
[07:52:05] <archivist> with molded on connectors its hard to get the cable through the case nicely
[07:53:00] <pcb_maker> but i have soooo many thing in the control panel..
[07:53:19] <pcb_maker> it is 4 by 2 by 1 foot
[07:54:02] <pcb_maker> so it is much easyer to put the C10 in the place and make a cble for it..
[07:54:03] <archivist> I am fitting mine in about 3x2x1
[07:54:37] <pcb_maker> also very nice size!
[07:55:57] <archivist> unfortunately the case I have has some silly wall mount brackets welded on, dunno if the angle grinder is going to get used yet

[08:32:14] <Deejay> hm, not that much. build my own little cnc mill
[08:32:22] <Deejay> only using for hobby stuff
[08:32:51] <pcb_maker> me too but I have the G0704..
[08:33:07] <Deejay> making some xmas goodies from wood, or make boxes, engrave signs... mill pcb prototypes...
[08:33:39] <Deejay> but i use my cnc not very often
[08:33:59] <pcb_maker> I'm almost every day.
[08:34:14] <Deejay> for what? making pcbs all the time?
[08:34:16] <pcb_maker> I LOVE solidworks, so i make stuff.
[08:34:31] <Deejay> is your job cnc-concerned?
[08:34:34] <pcb_maker> no.. It's just a nick..
[08:34:40] <Deejay> i see
[08:34:45] <pcb_maker> no. total hobby..
[08:34:48] <Deejay> nice
[08:35:02] <Deejay> so what do you make on your cnc all the time?
[08:35:25] <pcb_maker> now I make the parts for the new panel
[08:35:33] <pcb_maker> I can show you
[08:36:59] <pcb_maker> one sec
[08:37:08] <pcb_maker> I will tke a pic for you

[08:44:32] <Deejay> what are the two empty slots for?
[08:44:44] <Deejay> rotary axis?
[08:45:15] <pcb_maker> I have 4 drivers and 4 motors, but I've just connect 3 axis
[08:46:11] <pcb_maker> so it is just 200-300$ to upgrade to 5 motors and drivers, and it fit vey nice in the canel
[08:46:21] <pcb_maker> so I make the place for it.

[09:05:39] <just_pink> what is the small key pad on the dark gray thing?
[09:06:24] <just_pink> archivist: ?
[09:06:27] <archivist> that is the VFD it has a keypad for manual use
[09:07:05] <just_pink> you have a servo spindle?
[09:07:20] <just_pink> or just speed control?
[09:07:39] <archivist> not a servo spindle just a normal 3phase motor
[09:07:58] <just_pink> you are from the us?

[09:13:06] <archivist> yes I did see it
[09:14:30] <just_pink> you can do tapping with it?
[09:14:43] <archivist> my case is the heatsink, your cable trunking may obstruct the airflow
[09:15:36] <archivist> tapping and hobbing will be added when the spindle feedback is finished
[09:16:49] <just_pink> there is 5 fans and the heatsink is go thru the back of the panel
[09:16:59] <archivist> but that is not the only way of threading on a mill http://www.collection.archivist.info/searchv13.php?searchstr=thread+milling

[09:18:54] <archivist> 5 fans? noisy
[09:19:17] <just_pink> not
[09:19:41] <just_pink> not that noisy. it on the back..
[09:19:53] <archivist> you may not need fans at all on those
[09:20:52] <just_pink> there is 4" between the fan and the wall. and also i have temp sensors everywhere.. so i can manage it..

[14:09:26] <os1r1s> I can make the normal labels and leds respond with no problem. Buttons are easy. But these simply aren't updating. Any thoughts archivist?
[14:09:48] <archivist> not connected properly
[14:10:12] <os1r1s> archivist: What pin/signal represents the DROs in the HAL?
[14:10:28] <archivist> dont forget some cannot be connected until postgui
[14:10:35] <os1r1s> I can build a net, but can't find which variable to link it to
[14:10:47] <os1r1s> I'm doing them in postgui
[14:11:04] <archivist> use halshow to see what is available
[14:11:39] <os1r1s> Thats what was using for my LEDs and labels, but I can only find the tool offsets listed there.
[14:12:01] <os1r1s> I can't find the fixture or world coordinates listed. (Even though they are in the DRO combo)

[14:17:12] <mozmck> os1r1s: I've used HAL_DROs without any problem.
[14:17:32] <os1r1s> mozmck: Do you connect them to a net in the hal?
[14:17:52] <mozmck> no, I don't think they export a pin
[14:18:27] <os1r1s> And yours update properly? Hmm ....
[14:18:46] <mozmck> In glade you set the Joint Number, and the Reference Type
[14:19:30] <archivist> too many guis error :)
[14:19:47] <os1r1s> Ok, I did both of those. i have it in a table. Does that matter? I trust it doesnt' need to be a HAL_TABLE
[14:20:25] <mozmck> No, I have mine in an hbox inside a vbox
[14:20:51] <os1r1s> hmm
[14:21:40] <mozmck> There is also an option for Actual Position (vs commanded) - I don't know how it acts if that is set to No
[14:22:22] <os1r1s> Let me check that
[14:24:43] <os1r1s> mozmck: That was it
[14:24:58] <os1r1s> mozmck: It needed to be commanded vs actual. Actual doesn't update ...
[14:25:33] <os1r1s> mozmck: Thank you. One more question. How can you do a toggle that executes two different Gcodes for on vs off?
[14:32:03] <mozmck> os1r1s: well that's odd, because I have mine set to actual
[14:32:08] -!- moorbo has quit []
[14:32:45] <mozmck> Maybe the actual is tied to feedback somehow and your feedback is not showing the position change? I'm not quite sure how that works.
[14:32:47] <os1r1s> mozmck: Could it be a servo/stepper thing? Without encoders maybe actual isn't updated?
[14:32:48] -!- lerman has quit [Ping timeout: 264 seconds]
[14:33:10] <mozmck> I use steppers, so no encoders on my setup.
[14:33:14] <os1r1s> Hmm
[14:33:20] <mozmck> But it updates in sim just fine as well.
[14:33:43] <mozmck> What are you trying to turn on and off?
[14:34:18] <os1r1s> Ok, scratch that. Both work. The failure last night was in a table. Let me see if that is what breaks it
[14:34:42] <mozmck> hmm, I don't know what might cause that offhand.
[14:36:58] <os1r1s> Well crap. That's working too. I don't know what I did last night that caused it to stop. It seems to be working properly now.
[14:39:12] -!- ktchk has quit [Quit: ktchk]
[14:39:33] <os1r1s> mozmck: Do you happen to know how to make a toggle button send a a different gcode for enable/disable?
[14:39:57] <mozmck> enable/disable what?
[14:40:12] <os1r1s> mozmck: I want one button that will turn on Mist or turn it off.
[14:40:25] <mozmck> Are you using axis?
[14:40:25] <os1r1s> But I need to send an M7 to enable, or an M9 to disable
[14:40:28] <os1r1s> Yeah
[14:40:50] <mozmck> If you have Mist connected in HAL I think there should be a checkbox in Axis for it.
[14:42:18] <os1r1s> mozmck: Ahh, yep. I do see it. I don't have it connected in my sim. Thanks!
[14:42:54] <mozmck> Mine is connected like this: net coolant-mist iocontrol.0.coolant-mist hm2_7i92.0.gpio.005.out
[14:43:29] <mozmck> I made a custom GUI and I did make a toggle button for Mist, but it is much easier to use what is there if you are using Axis :)
[14:44:34] <os1r1s> I want to make a tab for probing next.
[14:45:24] <os1r1s> So if you call that iocontrol you can toggle it on and off? Or you had to do something more elaborate in the handler.py?

[16:46:24] <Jesseg> What's the point of G28 in a program? Is it supposed to re-calibrate (i.e. bump the limit switches) and re-find home, or does it just go to that position before going on to the first point on the job?
[16:47:06] <zeeshan> its just a predefined position
[16:47:10] <zeeshan> i use it for tool changes
[16:47:22] <zeeshan> its one position where i know there will be no crashes and i can easily change my tool
[16:47:24] <zeeshan> so instead of going
[16:47:29] <zeeshan> g0 x y z
[16:47:32] <zeeshan> you just go g28
[16:47:53] <zeeshan> and its always an absolute position
[16:48:00] <Jesseg> Okay, so I can see having it at the end of a program so when the job is done, tool is in a nice place
[16:48:14] <Jesseg> but why would it be near the top of a program?
[16:48:29] <zeeshan> lets say your program was stopped abruptly
[16:48:32] <zeeshan> cause you noticed it was gonna crash
[16:48:38] <zeeshan> and you modified the line of code at the crash
[16:48:41] <zeeshan> and re-ran the program
[16:48:48] <zeeshan> you wanna move to a safe position..
[16:48:55] <zeeshan> before you start your program
[16:49:04] <zeeshan> it ensures you start from the exact same position every time
[16:49:21] <Jesseg> oh, like re-homing?
[16:49:23] <Jesseg> Thanks!
[16:49:24] <zeeshan> like say 0 0 0 was your g28 position
[16:49:32] <zeeshan> and your next line was 5 0 0
[16:49:40] <archivist> I admit I have never used g28 iirc
[16:49:43] <Jesseg> ohhhh
[16:49:47] <zeeshan> but you crashed at 3,0,0
[16:50:02] <zeeshan> if you restarted your program from 3,0,0 it'd linearly go to 5,0,0
[16:50:06] <zeeshan> maybe crtashing into something
[16:50:13] <zeeshan> rather than going from 0,0,0 to 5,0,0
[16:50:49] <zeeshan> it's not rehoming (maybe you're using homing in a different context)
[16:50:52] <Jesseg> I see what you're saying. if home was z-max then it'd be good to start a program by going z-max before continuing in case the tool was off some place down deep where it'd dig a trench going to the first position
[16:51:07] <zeeshan> exactly!
[16:51:29] <zeeshan> that's how you get nyccnc's chewed up vise
[16:51:34] <zeeshan> :D
[16:51:46] <archivist> my programs have something different because I am backlash chasing,
[16:51:49] <Jesseg> so I guess I'd want G28 to go straight up, then to home position X/Y

[16:58:16] <archivist> depends on use case

[16:59:27] <zeeshan> these go to 2350F
[16:59:31] <archivist> just add a thermocouple, SSR and a controller

[17:16:24] <os1r1s> zeeshan: 4x8x8
[17:16:25] <zeeshan> does it weigh like 150lb?
[17:16:35] <os1r1s> zeeshan: No, like 30-50 at the most
[17:16:48] <os1r1s> And uses 110v
[17:16:49] <archivist> is that a big meter or a small kiln
[17:16:50] <zeeshan> i need like 20"x20"
[17:16:54] <zeeshan> rofl archivist
[17:16:58] <zeeshan> i got confused too
[17:17:16] <os1r1s> archivist: Small kiln. That was my test run when I first got it :)
[17:17:28] <os1r1s> But for little bits, it works perfect.
[17:17:39] <archivist> mine is tiny
[17:18:55] <zeeshan> do bricks cost 500bux each or something
[17:19:00] <zeeshan> why are these ovens like 2000$ new
[17:19:25] <os1r1s> zeeshan: The one I posted was $100 used

[17:25:04] <archivist> my bricks were under 30 quid for 8
[17:25:17] <zeeshan> brb
[17:25:22] <zeeshan> you should melt aluminum!

[18:56:15] <_methods> once he got his power supply working correctly it couldn't handle the demand i think
[18:56:40] <Tom_itx> kept overloading?
[18:56:44] <_methods> yeah
[18:56:57] <Tom_itx> or was it just set too high?
[18:57:05] <Tom_itx> and didn't show it
[18:57:19] <_methods> no idea but it looked like he had it set correctly
[18:57:28] <_methods> before it was set too low
[18:57:35] <_methods> and he wasn't getting a good oxide layer
[18:57:55] <Tom_itx> so the low v keeps it from burning?
[18:58:06] <Tom_itx> and the amps make it oxidize quicker?
[18:58:47] <_methods> yeah that's my take on it
[18:58:52] <_methods> like removing rust
[18:59:04] <_methods> but reverse
[18:59:41] <jt-alyeska> 6061 should be done at 15v and 12a ft2 for 1hr
[18:59:43] <renesis> low v just happens because its a low impedance circuit
[19:00:14] <renesis> its current regulated, he should be able to just set current, and have the voltage clamp down to whatever is neccessary to maintain that
[19:00:27] <_methods> until the oxide layer builds up
[19:01:29] <jt-alyeska> The pore size is important
[19:01:36] <renesis> right i would assume that increases the impedance of the part but maybe not the circuit as the wire would be pretty conductive still
[19:03:04] <zeeshan> i was saying last night, its only a hex crystal with a pore in it

[19:14:10] <PetefromTn_> one of the parts seemed to have taken the current better than the other which I can only contribute to a lesser contact to the wire supporting it
[19:14:33] <PetefromTn_> yes I did but that is not what the 720 rule seems to say
[19:15:10] <PetefromTn_> after dyeing the parts and then sealing them they were only slightly better than the last attempt
[19:15:24] <Tom_itx> i haven't formed an opinion either way but i do believe more current will shorten the bath time
[19:15:33] <Tom_itx> maintaining a low v
[19:15:35] <PetefromTn_> after some disappointment and wondering what is going on last night
[19:15:57] <PetefromTn_> I can only guess what is happening to cause the bad finish
[19:16:19] <PetefromTn_> today I went down to the wal mart and picked up some water based rit dye in black
[19:16:24] <PetefromTn_> and some more DI water
[19:16:29] <Tom_itx> your supply won't do more than 2ish amps?
[19:16:29] <jt-alyeska> From what ive read the 720 rule was developed by caswell for low power hobby anodizing
[19:16:47] <andypugh> What sort of wire are the parts connected with?
[19:16:54] <PetefromTn_> and I am planning to try to do the same thing only this time using a rit dye heated bath
[19:17:26] <_Sync_> neat, scored a lehmann rotary unit
[19:17:27] <PetefromTn_> the parts are suspended with Ti wire
[19:17:48] <andypugh> OK, that is what my local anodiser uses, so should be the right thing.

[20:11:32] <zeeshan> hi
[20:11:47] <zeeshan> i want that servo!
[20:14:37] <PetefromTn_> Okay just put some more cookies on
[20:14:40] <CaptHindsight> 0.00333333333 degrees
[20:14:56] <PetefromTn_> this time I am going double the amperage on a single part
[20:15:53] <PetefromTn_> setting up a black rit dye bath with the same sealer.
[20:16:02] <PetefromTn_> who knows what will work here
[20:16:17] <CaptHindsight> X X
[20:16:27] <CaptHindsight> fingers crossed lol
[20:16:48] <PetefromTn_> I am out of other ideas man.
[20:17:02] <CaptHindsight> it takes a bit of testing
[20:17:24] <CaptHindsight> other people have gotten no oxide on their first attempt
[20:17:40] <PetefromTn_> yeah but this is my FIFTH attempt heh
[20:17:54] <_methods> are you doing a desmut bath too?
[20:17:58] <CaptHindsight> I had someone come from India once that brought aluminum sheet with that they could anodize
[20:18:15] <PetefromTn_> yeah desmut/lye bath is done
[20:18:19] <CaptHindsight> ends up it wasn't aluminum sheet :)
[20:18:21] <PetefromTn_> that stuff is crazy powerful
[20:18:33] <CaptHindsight> they couldn't anodize
[20:18:44] <PetefromTn_> just a couple seconds and all the old anodizing comes off in sheets
[20:18:54] <zeeshan> lol CaptHindsight
[20:18:54] <PetefromTn_> that would suck
[20:19:28] <CaptHindsight> I still have the sheet. I'm not sure what mystery metal it is

[22:15:00] <_methods> shit nice
[22:15:04] <_methods> was that the rit dye?
[22:15:14] <PetefromTn_> this was a single part at 2.1 amps for 2.25 hours
[22:15:34] <PetefromTn_> immediately after anodizing tank dunked in a mixture of rit dye and DI water
[22:15:52] <PetefromTn_> then sealed in the caswell plating sealing mixture for fifteen minutes
[22:16:30] <PetefromTn_> I will admit that I put some wd40 on it so it is not really that shiny but as I understand it that is what you are supposed to do to recently anodized parts anyways
[22:17:00] <PetefromTn_> you can kinda tell because I did not try to get it down inside the slots
[22:17:13] <PetefromTn_> this is just off the line not ten minutes ago
[22:17:21] <PetefromTn_> do you think it looks okay?
[22:17:43] <_methods> looks good to me
[22:18:53] <PetefromTn_> there is STILL a touch of splotchiness here and there.
[22:19:14] <_methods> i see a bit down at the bottom of the pic
[22:19:18] <PetefromTn_> reading that link Tom just posted I got a few ideas about prepping the parts that I have not tried yet
[22:19:47] <PetefromTn_> if you could see it in person it is ALMOST what I am looking for
[22:20:06] <_methods> well you're a lot closer than you were yesterday then lol
[22:20:07] <PetefromTn_> I am kinda surprised that the RIT dye which I have read quite a few people complain about worked so well.
[22:21:21] <PetefromTn_> I mixed the rit dye with approx 5 cups of DI water to a 1/4 cup of rit dye and heated it to 130 degrees
[22:23:09] <CaptHindsight> PetefromTn_: what did you use for power?
[22:23:17] <PetefromTn_> the same power supply
[22:23:26] <os1r1s> PetefromTn_: Looking good
[22:23:27] <PetefromTn_> with the shunt meter set to 2.1 amps
[22:23:41] <PetefromTn_> for 2.25 hours
[22:23:51] <PetefromTn_> os1r1s thanks man
[22:23:57] <PetefromTn_> it is a very promising result
[22:24:04] <Tom_itx> you should try the same process with capn's dye now
[22:24:07] <PetefromTn_> it is still a touch blotchy on the surface
[22:24:16] <Tom_itx> but it's encouraging ehh?
[22:24:19] <PetefromTn_> Tom_itx I plan to
[22:24:32] <PetefromTn_> honestly I am not sure what I did wrong with the solvent dye
[22:24:44] <PetefromTn_> I dried the part thoroughly before it went in the dye
[22:24:57] <PetefromTn_> and dunked it for several minutes in the dye
[22:25:15] <PetefromTn_> then I let it air dry for quite awhile more than enough for a solvent dye to dry
[22:25:17] <Tom_itx> how long are you supposed to soak it in the dye?
[22:25:25] <PetefromTn_> before I submerged it in the sealer
[22:25:32] <PetefromTn_> which dye?
[22:25:37] <Tom_itx> capn's
[22:25:42] <CaptHindsight> the solvent dye is near instant
[22:25:49] <PetefromTn_> he seemed to say it does not take but a moment
[22:25:50] <Tom_itx> ok
[22:25:51] <PetefromTn_> yup
[22:25:55] <CaptHindsight> it's like a permanent marker
[22:26:01] <Tom_itx> what about he ritz dye?
[22:26:08] <PetefromTn_> it is just like a permenent marker
[22:26:36] <PetefromTn_> the rit dye I submerged and swirled it around in the mixture of about 5 cups DI water to 1/4 cup rit dye.
[22:26:52] <CaptHindsight> PetefromTn_: did you pour the dye back int the bottle between use?
[22:26:55] <PetefromTn_> it was actually pretty thick and as the water heated up it seemed to get even thicker
[22:26:58] <CaptHindsight> int/into
[22:27:12] <PetefromTn_> no I kept it in the trough with a cover on it
[22:27:36] <CaptHindsight> and I'm sure that the container was clean
[22:27:41] <PetefromTn_> it was brand new
[22:28:40] <PetefromTn_> I guess after this result the idea that I am not attaining a sufficiently thick anode layer is not accurate...the first time I cooked the parts I was apparently putting even more current into the parts for 2 hours
[22:28:55] <PetefromTn_> I know the process is pretty specific
[22:29:10] <PetefromTn_> but this was just an off the cuff guess really
[22:29:15] <PetefromTn_> thankfully it worked
[22:29:27] <PetefromTn_> and I am a lot closer to a perfect setup
[22:30:01] <PetefromTn_> It troubles me that I was unable to reproduce this with the solvent dye as I was hoping for a good result with that which would not require ANOTher heated bath
[22:30:20] <PetefromTn_> luckily the rit dye is not dangerous and we did it on the kitchen stove
[22:30:38] <PetefromTn_> now I have two more parts here to test with that have not been anodized yet
[22:31:23] <PetefromTn_> I will take them and clean the crap out of them adding some dawn dishwashing detergent in the kitchen sink and a thorough cleaning BEFORE I take it out to the line and use that aluminum degreaser bath from Caswell.
[22:31:53] <PetefromTn_> Also I will add that this time the part was soaked in the degreaser bath for a longer period of time BUT I did not heat it.
[22:32:29] <PetefromTn_> I will really clean the next parts and hopefully some of this last splotchiness will go away and the part will be perfect.
[22:35:46] <Tom_itx> seems the crevices were what wasn't perfect
[22:36:26] <Tom_itx> wonder if you should agitate the degreaser
[22:37:05] <CaptHindsight> whoisgotta surface grinder for a 4ft x 4ft plate?
[22:37:21] <Tom_itx> a bud of mine
[22:37:36] <Tom_itx> he used to make large presses

[22:38:43] <Tom_itx> iirc, anything bigger he sent to KC
[22:42:57] <Tom_itx> alot of things for 3M like stamping sandpaper, absorbent materials etc
[22:44:52] <Tom_itx> CaptHindsight, what are you grinding?
[22:47:00] <PetefromTn_> Tom_itx I agree
[22:47:12] <PetefromTn_> I just cleaned the crap out of the next test part
[22:47:19] <PetefromTn_> with dawn dishwashing soap
[22:47:28] <PetefromTn_> now it is sitting in the degreaser bath
[22:47:43] <PetefromTn_> once it is done I will do basically the same thing as I did last time
[22:47:55] <Tom_itx> i'd consider agitating the degreaser
[22:47:58] <PetefromTn_> I am tempted to try to do two parts again at the same time
[22:48:19] <Tom_itx> did you get your PSU figured out?
[22:48:32] <PetefromTn_> depends on your definition of figured out
[22:48:45] <Tom_itx> invest in a meter when you can
[22:48:55] <PetefromTn_> I am measuring with the shunt for 21 mv
[22:49:06] <PetefromTn_> which SHOULD be 2.1 amps or so
[22:49:17] <Tom_itx> that's 'in the ballpart' but not real accurate
[22:49:23] <PetefromTn_> what is strange is that is double what the part calls for
[22:49:23] <Tom_itx> ballpark
[22:49:37] <PetefromTn_> .1755 sq ft
[22:49:47] <PetefromTn_> according to the 720 calculator online
[22:49:55] <Tom_itx> like JT said, that thing you quoted was for hobbyists
[22:50:04] <PetefromTn_> which is setup for a 6A/sqft
[22:50:22] <PetefromTn_> I didn't quote anything it is just what I learned online
[22:50:28] <Tom_itx> that dude in the link used 12A /sqft
[22:50:45] <PetefromTn_> which coincidentally is probably what I just used
[22:50:57] <PetefromTn_> since I only did one part with the current setting for two
[22:51:50] <Tom_itx> my observations are that you could double the current keeping the voltage the same and cut your soak time down considerablly
[22:51:55] <CaptHindsight> Tom_itx: cast iron surface plate
[22:52:16] <PetefromTn_> that is basically what I did but I did not decrease the soak time
[22:52:28] <Tom_itx> CaptHindsight, unfortunately i don't know of any local grind shops
[22:52:28] <PetefromTn_> this went for 2.25 hours
[22:52:56] <PetefromTn_> there is a big blanchard grinding shop local to me but I am not sure you would want that
[22:53:22] <CaptHindsight> there are still shops around Chicago

[22:53:34] <CaptHindsight> just checking
[22:58:46] <Tom_itx> CaptHindsight, do you gain more oxide layer than is removed in the cleaning process with anodizing?
[22:59:03] <Tom_itx> ie the part is thicker after the process...
[23:00:58] <CaptHindsight> yes, it grows

[23:39:13] <XXCoder> whats best word for searching devices that convert 110v to 120v
[23:39:17] <XXCoder> err 220v
[23:39:36] <CaptHindsight> transformer
[23:40:16] <XXCoder> thanks
[23:40:24] <XXCoder> trying to find 500w version
[23:40:34] <malcom2073> Be aware, you can't convert US 110 to EU 220
[23:40:34] <XXCoder> I bought 50w and fur pointed out my idiotacy lol
[23:40:37] <malcom2073> erm
[23:40:38] <malcom2073> sorry
[23:40:41] <malcom2073> I'm wrong heh
[23:40:47] <malcom2073> It's you can't convert US 220 to EU 220 easily
[23:41:00] <malcom2073> Or US 110 to US 220
[23:41:01] <XXCoder> yea not using 220 lol
[23:41:10] <XXCoder> though why?
[23:41:19] <CaptHindsight> 60hz to 50hz is another story
[23:41:33] <malcom2073> US 220 is split. Each line of 220 is 110, just 180 degrees apart
[23:41:44] <malcom2073> 110 is a 110 line, and neutral
[23:41:48] <XXCoder> ah 110 v to -120v
[23:41:51] <XXCoder> er 110
[23:42:12] <malcom2073> Right, that's what US 220 is
[23:42:26] <XXCoder> heyy some good ones on amazon
[23:42:27] <malcom2073> EU 220 is actualy 220v and neutral
[23:42:39] <XXCoder> I rather buy from amazon than aliexpress
[23:42:50] <CaptHindsight> 120/240 delta or 120/208 wye
[23:45:23] <CaptHindsight> XXCoder: you want just a transformer with leads hanging off the body pr a box with cords and outlets mounted on it?

[23:46:22] <XXCoder> think this'll do http://www.amazon.com/Goldsource-STU-750-Voltage-Transformer-Converter/dp/B0022TL1BE/ref=sr_1_1?s=electronics&ie=UTF8&qid=1436744648&sr=8-1&keywords=110v+to+220v+transformer+600w
[23:46:46] <CaptHindsight> heh + USB
[23:47:13] <XXCoder> yeah nice bonus, recharge my phone at cnc router area lol
[23:47:27] <CaptHindsight> XXCoder: 50 hz spindle motor?
[23:47:51] <XXCoder> and I assume it is chinese shit so I rather have bit higher rating than what I will use.
[23:48:21] <CaptHindsight> oh is this for the spindle controller?
[23:48:29] <XXCoder> no spindle itself
[23:48:39] <XXCoder> its not really spindle but router
[23:48:42] <os1r1s> Woot woot. Looks like the cam is close to working with linuxcnc in a simulator. Getting closer.
[23:48:45] <CaptHindsight> an induction motor?
[23:48:52] <XXCoder> its only one that will fit my router :(

[23:49:18] <PetefromTn_> os1r1s ?
[23:49:31] <XXCoder> os1r1s: what cam?
[23:50:21] <os1r1s> PetefromTn_: Got bobcad putting out gcode that linuxcnc is simulating a path with. Certainly not that complex, but it is a thrilling victory.
[23:50:25] <CaptHindsight> XXCoder: should of said it's for a 220 die grinder, yeah that will work
[23:50:44] <XXCoder> I did say 220v :)
[23:50:47] <XXCoder> yea
[23:50:47] <PetefromTn_> Oh okay
[23:51:51] <XXCoder> no prices on website in most cases for bobcad. I cant afford it lol
[23:52:02] <XXCoder> cheapest its still more pricy than my entire machine LOL
[23:52:10] <XXCoder> (the only listed price)
[23:52:41] <XXCoder> oh CaptHindsight that is what I orginially bought http://www.aliexpress.com/item/Step-Up-Voltage-Converter-Adapter-110V-US-to-220V-US-EU-Black/1910410399.html
[23:52:56] <XXCoder> I didnt see 50w thing lol
[23:53:08] <CaptHindsight> yeah too small
[23:53:26] <XXCoder> furrywolf saved my ass
[23:54:05] <CaptHindsight> your grinder will also spin at 60hz faster than at 50hz
[23:54:38] <XXCoder> will this work http://www.amazon.com/Seven-Star-750W-Step-up-Transformer/dp/B002HFJ1ZG/ref=sr_1_5?ie=UTF8&qid=1436745222&sr=8-5&keywords=110v+to+220v+transformer+750w
[23:54:55] <XXCoder> seems yes to me
[23:55:02] <XXCoder> it works both ways but actually cheaper
[23:55:15] <PetefromTn_> my spindle motor is 50 HZ LOL
[23:55:19] <XXCoder> that is, before shipping
[23:55:24] <CaptHindsight> yes, less fancy enclosure
[23:55:26] <XXCoder> guess not worth it
[23:55:38] <CaptHindsight> the fun of Amamzon
