[00:01:11] <dirty_d> im curious, how do these actually work?
[00:01:23] <CaptHindsight> the 20th century was pretty kewl
[00:01:31] <dirty_d> does it just buffer steps, or does it process gcode
[00:01:48] <andypugh> talking of wiring, I found this powering my oven. On the far side of a 1.5mm2 wire and a 40A breaker: https://picasaweb.google.com/108164504656404380542/CNCUnsorted?norediirect=1#5506480949142923826
[00:02:01] <fluffybitchx> Connor: I still can't find any prohibition on what you're doing.
[00:02:06] <CaptHindsight> where s that block diagram of Linuxcnc again?
[00:02:43] <andypugh> dirty_d: It does neither. It creates step pulses at the commanded rate until told to change the rate. No buffering.
[00:02:46] * fluffybitchx would have to find a table to know what 1.5mm2 translates to in real wire sizes
[00:03:17] <fluffybitchx> looks nice and melty, possibly because of incorrectly sized wire and/or connector.
[00:03:44] <andypugh> The wire sizes are only one problem Wires at he sides of the screws are bad. Earth clamped on to the insulation is special too.
[00:04:04] <CaptHindsight> dirty_d: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?EMC_Components
[00:04:06] <fluffybitchx> the wire is on the side because the wire and connector are rather mismatched.
[00:04:11] <andypugh> Yes.
[00:04:23] <fluffybitchx> if they were the right size for each other, it wouldn't fit in the side.
[00:04:51] <fluffybitchx> the real problem, as always, is horribly incompetent people doing wiring... although that might go beyond incompetence and into plain mental defectiveness.
[00:04:52] <dirty_d> andypugh, an arduino could do that, and youd still have the latency between wanting to change the step rate, and it actually changing the step rate.
[00:05:10] <andypugh> I think that is 8A wire on a 40A breaker. 8A is fine for the cooker, but the breaker should match the wire.
[00:05:26] <CaptHindsight> dirty_d: http://wiki.linuxcnc.org/uploads/EMCmsg_resize.png
[00:05:58] <andypugh> dirty_d: The Mesa card also drives the signals with real voltages. And 10Mhz would be a push for an Arduino
[00:06:07] <dirty_d> is that mesa board "IO Controller" on there?
[00:06:16] <CaptHindsight> http://wiki.linuxcnc.org/uploads/EMC_Control_LG.gif
[00:06:23] <dirty_d> andypugh, fine, a $15 stm32 board, lol
[00:06:34] <andypugh> It also has 32 IO pins which are serially addressed, and you can hook up a bunch more.
[00:06:42] <fluffybitchx> I occasionally get asked to fix houses that growers fucked up... one of them had a 50A 240V breaker running through a #14 115V extension cord.
[00:07:10] <andypugh> dirty_d: There are, of course, lots of solutions. But the Mesa boards work and have drivers and config generators.
[00:07:10] <fluffybitchx> growers seem to be some of the least intelligent people on the planet. I suspect they sample their product while doing wiring...
[00:07:53] <andypugh> dirty_d: How do you intend to send the step rates to the putative Arduino? (hint, USB won’t work)
[00:08:17] <fluffybitchx> I still think usb CAN work with appropriate software.
[00:08:52] <dirty_d> andypugh, see thats the part im not understanding about how the mesa board will fix this. If the rtai thread runs late, then the command to the mesa board is gonna be late too.
[00:09:21] <CaptHindsight> the RTAI thread doesn't run late
[00:09:24] <andypugh> Aye, but the Mesa firmware has a DPLL loop and sort-of notices.
[00:09:27] <fluffybitchx> have the step generator ramp down the steps at a set deceleration if it doesn't receive another pulse update within a set time frame, so if latency goes to hell, it just slows down, rather than over-cuts.
[00:10:05] <dirty_d> CaptHindsight, what do you mean?
[00:10:22] <dirty_d> that seems kinda hackish
[00:10:56] <CaptHindsight> dirty_d: if you are software stepping you set the thread rate to be longer than what the max latency is, so the thread is never late
[00:11:03] <dirty_d> if youre going to have external hardware, i feel like that should alleviate any realtime responsibility from the PC
[00:11:16] <andypugh> Basically every 1mS the Mesa card says “I made this many steps last mS, how many should I make next mS” and if it wasn’t exactly 1mS it still works because the step rate itself is accuratley clocked and ramped at known accellerations. The parport can just miss a step and stall the motor.
[00:11:59] <CaptHindsight> ^^
[00:12:50] <andypugh> dirty_d: But in your situation I would actually stick with the parport for a while and see if the latency glitches actually matter.
[00:12:56] <dirty_d> yea but what if that happens right at a corner or something
[00:13:20] <dirty_d> andypugh, yea im just going to increase that base period or whatever it is
[00:13:28] <dirty_d> that will just limit my max speed right?
[00:13:32] <andypugh> But when you run out of IO pins the Mesa stuff makes more sense than a second parport card.
[00:13:34] <CaptHindsight> yes
[00:14:19] <CaptHindsight> andypugh: whatcha working on this weekend?
[00:14:28] <dirty_d> ive never seen my jitter go over 81,000, so if i set the base period to 100,000, what would my max step rate be?
[00:14:43] <dirty_d> its not just 100,000 steps/s i would think
[00:14:45] <dirty_d> right?
[00:14:50] -!- pandeiro has quit [Remote host closed the connection]
[00:14:51] <dirty_d> i mean
[00:14:57] <dirty_d> you knowwhat i mean, lol
[00:15:13] <dirty_d> 1/100e-9 steps/s
[00:15:32] <andypugh> CaptHindsight: My parent’s house. Making-good the floor inside a new doorway (and door) I made.
[00:15:53] <andypugh> Last time I went up there I fired up the forge and made the door furniture.

[00:23:10] <dirty_d> im overthinking this
[00:23:38] <dirty_d> even if i set my base period to 150us, i can still move at about 50in/min with 1/8 microstepping
[00:23:44] <dirty_d> im happy with that
[00:24:37] -!- rob_h has quit [Ping timeout: 250 seconds]
[00:29:45] <andypugh> There is a little more to it than that
[00:30:08] <zeeshan> andypugh: nice fancy boring head
[00:30:35] <andypugh> The problem is that at 100uS you can do 10kHz. Or you can do 5kHz. And the motors won’t follow that jump.
[00:31:07] -!- patrickarlt has quit [Remote host closed the connection]
[00:31:29] <andypugh> zeeshan: You mean this one? https://picasaweb.google.com/108164504656404380542/CNCUnsorted?norediirect=1#5998926150725388018
[00:32:27] <zeeshan> that opened an entire album
[00:32:40] <andypugh> I hate google
[00:32:43] <zeeshan> hehe
[00:32:46] <dirty_d> hmm, 2.6.5 doesn't show the toolpath of the loaded program?
[00:33:28] <dirty_d> nevermind, im getting an error, i think thats why
[00:33:50] <dirty_d> 'NoneType' object has no attribute 'rfind' when i load the file
[00:34:23] <andypugh> zeeshan: Ah, I can’t tyoe. https://picasaweb.google.com/108164504656404380542/CNCUnsorted?noredirect=1#5998926150725388018
[00:34:39] <zeeshan> yes that one
[00:34:40] <zeeshan> its bad ass
[00:34:50] <andypugh> dirty_d: That sounds like a Python error code.
[00:35:05] <andypugh> zeeshan: It’s also probably unique :-)
[00:35:13] <dirty_d> yea it is
[00:36:33] <FinboySlick> What's the connector for on that boring head, andypugh?
[00:36:58] <andypugh> It drives the servo motor in the boring head :-)
[00:37:16] <FinboySlick> CNC boring head! Wow.
[00:37:47] <FinboySlick> How did you do the sliding contacts?
[00:37:49] <andypugh> Custom motor: https://picasaweb.google.com/108164504656404380542/CNCUnsorted?noredirect=1#5685047047296097794
[00:38:20] <andypugh> It’s all brushless and optical, no sliding contacts.
[00:38:58] <andypugh> (I do think it is the cleverest thing I have ever done)
[00:39:10] <FinboySlick> Ah right. Rotor is the magnetic part and connected to the spindle.
[00:39:36] <andypugh> Yes. and there are two encoders.
[00:40:03] <FinboySlick> One to synch with the rotation and one for relative movement?
[00:40:38] <andypugh> Indeed.
[00:40:51] <dirty_d> it was just an error in my ini file
[00:40:55] <andypugh> One of those “I need to get out of bed and write this down” ideas.
[00:43:04] <zeeshan> its bad ass
[00:43:06] <FinboySlick> You have to sync to the spindle encoder too, right?
[00:43:06] <zeeshan> thats what it is :)
[00:45:11] <FinboySlick> Hehe, show it to DMG MoriSeiki and give them non-exclusive rights to it in exchange for your pick of machine ;)

[00:45:52] <dirty_d> theres no way to see the max latency while linuxcnc is running right?
[00:46:26] <andypugh> dirty_d: I think there is
[00:46:32] -!- farbro has quit [Ping timeout: 245 seconds]
[00:47:26] <dirty_d> theres a "show linuxcnc status" in the machine menu, but i dont see latency in there.
[00:48:06] <andypugh> I am searching the docs
[00:48:18] <zeeshan> https://www.dropbox.com/s/cknhoiggmrt64g0/speed%20selector.pdf?dl=0
[00:48:21] <zeeshan> CaptHindsight: better?
[00:48:36] <dirty_d> well, thats alarming, acceleration: 1e99
[00:48:57] <andypugh> That’s quite high
[00:49:13] -!- moorbo [moorbo!~moorbo@198.211.113.93] has joined #linuxcnc
[00:49:51] <andypugh> dirty_d: You can plot latency on a histogram: http://www.anderswallin.net/2012/12/real-time-tuning/
[00:49:59] <zeeshan> after rearranging stuff
[00:50:07] <zeeshan> it looks like this circuit board has 2 seperate circuits on it.
[00:50:31] -!- moorbo_ has quit [Ping timeout: 255 seconds]
[00:51:15] <zeeshan> it looks like if i give 24vdc to pin 5
[00:51:20] <zeeshan> and ground either pin 8 or 9
[00:51:37] <zeeshan> i _should_ be able to switch the hall switches using a magnet
[00:51:54] <zeeshan> and seeing a change of state on pin1,2,3,4,11,12
[00:52:18] <CaptHindsight> zeeshan: more stuff, new features, more secrets
[00:52:24] <zeeshan> lol capt
[00:52:35] <andypugh> dirty_d: Interesting… There is a script in the LinuxCNC scripts folder which creates histograms, and as far as I can see it has no documentation, other than a vague hint in a related manpage: http://www.linuxcnc.org/docs/html/man/man9/latencybins.9.html
[00:54:05] <dirty_d> hmmm
[00:54:10] <PCW> The histogram is fun to play with
[00:54:34] <PCW> as is halscoping various linuxcnc function times
[00:56:13] <PCW> zeeshan: that sensor board actually looks like it was made to work with 7I77 style inputs
[00:56:35] <zeeshan> yea it has pnp transistors
[00:56:51] <zeeshan> im a noob in electronics so i am confused about why it wasn't working last time
[00:56:58] <zeeshan> i tried to give 24vdc and ground the board
[00:57:10] <zeeshan> and then tried to put a magnet on the sensors and measure output on pins
[00:57:12] <dirty_d> does this give any hints as to anything i can disable? http://pastebin.com/xCnfe2Rm
[00:57:13] <zeeshan> and it didnt do anything really
[00:58:28] <dirty_d> cant run latency-histogram with linuxcnc running too
[00:58:31] <dirty_d> but its still cool
[01:01:25] <PCW> is that a 12V regulator for the Hall sensors?
[01:01:52] <PCW> might check the output there
[01:02:47] -!- Nick001-shop has quit [Quit: ChatZilla 0.9.91.1 [Firefox 34.0.5/20141126041045]]
[01:05:55] <zeeshan> yes its a 12v regulator
[01:05:58] <zeeshan> l7812
[01:06:35] -!- Loetmichel2 [Loetmichel2!~cylly@p54B119D1.dip0.t-ipconnect.de] has joined #linuxcnc
[01:07:01] <PCW> outputting 12V?
[01:07:12] <zeeshan> it was a while ago, but yea i remember it putting out 12v
[01:08:04] -!- Loetmichel has quit [Ping timeout: 255 seconds]
[01:08:16] <PCW> so the hall devices should switch with a strong enough magnet pointed the correct way
[01:08:34] <zeeshan> what should i be seeing between say pin 1 and gnd?
[01:08:40] <zeeshan> with no mag field?
[01:08:53] <andypugh> I spent two days hacking about with my Inventor add-in Slicer for DLP trying to get the SVG right. Then I found the SVG is right in Chrome, but not right in Inkscape. It’s an Inkscape bug!
[01:10:01] <FinboySlick> andypugh: Could be something with Cairo. I suspect that Chrome might not be using it.
[01:10:20] <andypugh> The file (tiny) is here: https://bugs.launchpad.net/inkscape/+bug/1421865/+attachment/4319053/+files/newfile.svg
[01:11:06] <FinboySlick> Firefox appears to render it right (assuming it's an ellipse with a flattened top)
[01:11:15] <andypugh> If anyone has something other than Inkscape or Chrome I would be interested to see if it comes out symmetrical top-to-bottom
[01:11:28] <andypugh> Yes, it is.
[01:11:44] <andypugh> It comes out vaguely pear-shaped in Inkscape
[01:11:59] <PCW> either low (<1V or) high = 24V but there's some diode logic so multiple halls may need to be triggered to get a high level
[01:12:02] <ssi> https://www.youtube.com/watch?v=J9b0J29OzAU#t=61
[01:12:06] <ssi> neat
[01:13:15] <PCW> Thats really cute
[01:14:18] <ssi> isn't it? :D
[01:16:00] <andypugh> I posted that to the mailing list a few days ago
[01:16:10] <andypugh> It’s inspired.
[01:16:14] <FinboySlick> http://pbrd.co/1Eot2vv http://pbrd.co/1Eot9Y2 is how GIMP renders it.
[01:16:17] <ssi> :D
[01:16:38] <andypugh> Gimp wins them
[01:16:49] <FinboySlick> First image is Firefox.
[01:16:53] <FinboySlick> (the zoomed in one)
[01:17:21] <FinboySlick> I'm pretty sure both GIMP and Firefox use Cairo.
[01:17:51] <andypugh> Inkscape: http://ibin.co/1rZTXM05K7Hl
[01:18:09] <FinboySlick> Wow, that's quite a difference.
[01:18:35] <andypugh> Yeah, especially when the target is a DLP printer and these are engineering parts…

[01:46:21] <_methods> i think i got a set of those
[01:47:32] <_methods> nope i'm a liar
[01:47:48] <PetefromTn_> hehe I'll trade you one for one of those nice boring facing heads you got andy LOL
[01:48:06] <XXCoder> gonna love involunary lying lol
[01:50:12] <andypugh> PetefromTn_: I actually have ni use for the UPA4. But it is on an MT4 shank (fixed)
[01:50:43] <PetefromTn_> jeez Oh well
[01:50:44] <XXCoder> nice use?
[01:50:50] <XXCoder> or knights who say ni?
[01:50:57] <andypugh> I only keep the UPA4 because it is the most beautifully-made thing I have ever handled
[01:51:01] <ssi> andypugh: I want those dividers too
[01:51:29] <andypugh> I think that a UPA4 is 8k new
[01:51:55] <mozmck> andypugh: are you running the latest version of inkscape? they just released 0.91
[01:52:17] <andypugh> Yes, 0.91 Mac and PC render identically
[01:53:15] <mozmck> bummer
[01:54:22] <_methods> i had a chinese knock off pair lol
[01:54:24] <andypugh> PetefromTn_: There is an R8 and an 30 taper hiding inside an MT4, of course. Or one could cut the MT4 off short and modify to take the standard Wohlhaupter (super clever) differential-screw shanks.
[01:54:24] <_methods> go figure
[01:56:01] <andypugh> PetefromTn_: I paid 150 euros for it, if you want it, and pay 150 euros + shipping and promise to appreciate it, you can have it.
[01:57:08] <andypugh> (I have had it a few years and have had my money’s-worth in “That’s lovely, thta is”)
[01:57:26] <ssi> heheh
[01:57:35] <PetefromTn_> hehe but I thought you said it was MT4 fixed?
[01:57:52] <andypugh> Yeah, but MT4 is made of metal.
[01:58:11] <andypugh> Everyone here re-shapes metal for fun
[01:58:21] <ssi> indeed!
[01:58:27] <ssi> so I got to do something fun today
[01:58:38] <ssi> I'm working on those pitts wings, and I realized that we missed someting in the drawings
[01:58:59] <ssi> there's 4130 plates sandwiching the butt end of the spars with some 1/4" holes through for bolts
[01:59:12] <ssi> and the plans call for those holes to be bushed with 4130 tubing, 3/8x.058" wall
[01:59:22] <_methods> heh i never figured i'd have room to use my coax on the x2
[01:59:25] <ssi> but the wings are already assembled, and drilling those holes was going to be quite hard
[01:59:37] <PetefromTn_> I would LOVE to have it man but I don't even have a lathe here anymore and machining that thing to accept a Cat40 would have to be absolutely perfect setup or you would screw the pooch LOL
[02:00:10] <_methods> http://imgur.com/7dxNa5a
[02:00:12] <ssi> so my friend BJ took me up to Delta's maintenance hangar at Hartsfield, and we went to the tool crib and checked out a .373x.248 1" LOC core drill with a 1/4-20 shank for use with a 90 drill
[02:00:16] <ssi> which I have
[02:00:25] <ssi> made short work of those holes!
[02:00:31] <ssi> otherwise I was going to have to try to make something custom :P
[02:01:07] <PetefromTn_> kinda surprised that the head is not made to accept different shanks
[02:01:22] <ssi> https://pbs.twimg.com/media/B9xRGzGIAAAfqhR.jpg:large
[02:01:38] <ssi> here's the drill I got from Delta
[02:01:38] <ssi> https://pbs.twimg.com/media/B9xRHcsIQAE6f_C.jpg:large
[02:02:33] <ssi> I was actually contemplating taking a 3/8" twist drill, annealing it, turning the threaded shank and pilot, and rehardening
[02:02:48] <ssi> but I've heard annealing HSS is a bitch
[02:02:52] <mozmck> andypugh: here's your image in my inkscape: http://pbrd.co/1EoDK59
[02:03:18] <andypugh> PetefromTn_: Actually you would have to mess up the shank attachment on a boring head really quite spectacularly for it to matter at all.
[02:03:19] <mozmck> I'm running trunk from the PPA on LinuxMint 17.1

[02:04:47] <andypugh> Could you add that info to the bug tracker I posted?
[02:04:57] <XXCoder> probably broweser issue
[02:05:06] <mozmck> andypugh: let me try.
[02:05:08] <andypugh> Yeah, it looks spot-on to me
[02:05:19] <XXCoder> now it works
[02:05:31] <XXCoder> permission issue for me lol
[02:05:37] <mozmck> ah.
[02:05:51] <mozmck> pasteboard is pretty nice - I had not seen that site before.
[02:06:06] <XXCoder> new site idea

[02:16:51] <Connor> OKay, I'm starting to think it might be a bad idea to wire the dishwasher and disposal up on the same circuit..
[02:17:11] <Connor> Disposal is 6.9amps. I can't find any amps info on the current dishwasher.
[02:17:46] <zeeshan> is it old?

[02:18:32] <zeeshan> Connor: i know nec says something about dishwasher specifically.
[02:18:35] <Connor> It's always been on it's own circuit and the disposal was on another branch.
[02:18:38] <zeeshan> that it needs to be on its own circuit
[02:18:43] <zeeshan> 14 awg minimum
[02:18:50] <Connor> I use 12.
[02:21:58] <Connor> Requirements for GFCI protection in dwelling unit kitchens have been expanded. A new subdivision (D), “Kitchen Dishwasher Branch Circuit,” has been added to 210.8. Outlets supplying dishwashers are required to be GFCI-protected, which requires a GFCI-protective device installed at the origin of the branch circuit. The reason is related to different end-of-life failure modes and behavior of newer generation dishwashers as compared to the electromechanic
[02:22:19] <Connor> Origin of the branch circuit ?

[02:24:09] <ssi> gfci breaker
[02:24:22] <ssi> as opposed to a gfci outlet at the dishwasher or something
[02:25:17] <Connor> I'm adding outlets for the disposal and dishwasher.. both were hardwire..
[02:25:40] <ssi> sure
[02:25:49] <Connor> okay.. so.. change of plans... separate outlets..
[02:25:56] <ssi> well "at the origin of the branch circuit" means use a gfci breaker in the panel rather than a gfci outlet
[02:26:07] <Connor> right.
[02:26:34] <Connor> I was going to use a blank gfci like this.. http://www.westsidewholesale.com/leviton-x7590-t.html?keyword=Google_Shopping&mr:trackingCode=FE3919B3-12C8-E311-B4D3-BC305BF933C0&mr:referralID=NA&mr:device=c&mr:adType=plaonline&mr:ad=56682935845&mr:keyword=&mr:match=&mr:filter=91797739165&gclid=CjwKEAiA3vamBRDJ1Lfwt5Pckw4SJAAdhnk2fHgFEevFg0_nvF0BsZcfzdfeaUE9c6zY_N3nRwFnZBoCLjjw_wcB
[02:26:38] <roycroft> is that nec or your local electrical code?
[02:26:45] <Connor> NEC
[02:26:53] <roycroft> i think it's a good idea, but if you're trying to save money, see if your local code requires it
[02:27:04] <roycroft> most local codes adopt nec and amend it
[02:27:04] <ssi> Connor: http://www.homedepot.com/p/Square-D-Homeline-20-Amp-Single-Pole-GFCI-Circuit-Breaker-HOM120GFICP/100002959
[02:27:24] <roycroft> is this a new circuit?
[02:27:28] <Connor> No.
[02:27:30] <Connor> Existing.
[02:27:34] <roycroft> ok, so there may be a problem
[02:27:47] <roycroft> and that is that a gfci breaker has its own neutral wire
[02:27:52] <roycroft> and you connect that to the neutral bus
[02:28:01] <roycroft> then you connect the neutral wire for the circuit to the breaker
[02:28:09] <roycroft> and it may not reach the breaker if it's existing wiring
[02:28:23] <ssi> and on the fourth day, god created wire nuts
[02:28:27] <ssi> :D
[02:28:31] <roycroft> which may or may not be legal
[02:28:33] <Connor> It's a dedicated 12-2 all the way to the panel.
[02:28:37] <roycroft> right
[02:28:48] <roycroft> but will the existing neutral wire reach the new gfci breaker?
[02:29:06] <Connor> Oh. I have no idea.
[02:29:13] <Connor> I would have to open up the panel and look
[02:29:13] <roycroft> that is something you need to determine
[02:29:29] <roycroft> and also need to determine whether your local code allows you to extend it inside the panel
[02:29:32] <Connor> Looks like this break has it's own neutral "pigtail"
[02:29:35] <roycroft> right
[02:29:42] <roycroft> that's what all gfci circuit breakers have
[02:29:59] <Connor> I have slack on the wire..
[02:30:07] <Connor> I can pull more back into the box.
[02:30:07] <ssi> Connor: yea cause you have to pass the neutral thru the breaker so it can detect current on it
[02:30:12] <roycroft> if there's enough slack then you're good to go
[02:30:19] <roycroft> correct
[02:30:47] <Connor> okay.. So. GFCI Breaker at the box. (maybe not now)
[02:30:50] <roycroft> a gfci breaker detects if more current is going through the hot wire than is returning through the neutral wire
[02:30:58] <roycroft> if that's the case then it pops
[02:31:13] <roycroft> so it has to have the neutral for the circuit isolated from the rest of the power bus
[02:32:17] <roycroft> i would recommend gfci breakers for any circuits that feed wet areas, regardless of whether local code requires it or not
[02:32:22] <roycroft> it's just a good, safe thing to do
[02:32:29] <ssi> agreed
[02:32:30] <Connor> yea.
[02:32:54] <roycroft> your or your loved ones' lives are worth more than the $30 or so extra you pay for the breaker
[02:32:55] <Connor> okay.. so.. now the disposal.. it was being supplied by existing branch in the kitchen.
[02:33:07] <Connor> no GFCI in kitchen at all.
[02:33:24] <roycroft> i would recommend a gfci breaker for the whole branch circuit
[02:33:29] <roycroft> then everything is protected
[02:33:41] <Connor> That one is a bit harder to do.. it's very old wiring..
[02:33:45] <Connor> and probably no slack.
[02:34:03] <roycroft> in that case if code requires gfci and permits a gfci receptacle then do that
[02:34:09] <roycroft> however
[02:34:30] <Connor> Within in 6' of sink area I think..
[02:34:38] <roycroft> i would not install the gfci receptacle by the disposal
[02:34:44] <roycroft> i would trace the wires
[02:34:56] <Connor> I don't have to trace them. I know where they go.
[02:34:59] <roycroft> and find the first receptacle in the kitchen (closest to the panel)
[02:35:05] <roycroft> and put the gfci receptacle there
[02:35:12] <roycroft> that protects that outlet and everything downstream
[02:35:27] <Connor> Yea. Only 2 options for that.
[02:36:29] <Connor> I may have to upsize the box. I barely got the outlet and the wirenuts in it last time. I don't think a GFCI will fit..
[02:36:35] <Connor> very very old metal box.
[02:38:10] <roycroft> that's often a problem
[02:38:14] <roycroft> so there may be another option
[02:38:24] <roycroft> is there a place where the cable run is fairly exposed?

[02:38:41] <roycroft> i.e. surface mount conduit or romex in an attic?
[02:38:51] <roycroft> you may be able to put a junction box in the middle of the circuit

[02:47:42] <Connor> okay. So.. The wall opposite the fridge/mircowave/dishwasher has a outlet. It's the start of a branch.. and feeds the outlet for the microwave and the fridge. Could be attached to another room.. I'm not sure.
[02:47:55] <Connor> dishwasher has it's own circuit.
[02:48:49] <Connor> then on the wall with the stove.. I have 2 outlets, a switch for exhaust fan. this was the circuit handling the disposal.
[02:50:12] <Connor> and of course the switch for the disposal. the start of the branch is that one outlet that's has 3 sets of romex coming into it.. the feeder, 1 for the daisy chain (exhaust fan then outlet then disposal) and it also feeds the range hood.
[02:50:42] <Connor> that box is going to have to be upsized.

[04:21:20] <fluffybitchx> the depth changes are due to only supporting the piece from the far end, and it getting pulled up by the endmill. was just a test, and didn't want to rig up a fixture.

[04:24:01] <XXCoder> ohh
[04:24:06] <XXCoder> not bad
[04:24:38] <fluffybitchx> I just tossed a piece of wood on the mill and cut. surface finish was not a priority. if I cared, I'd have clamped the piece better. lol
[04:24:57] <XXCoder> true it is test after all
[04:25:07] <RyanS> If I find the work surface on Z to zero a DRO on a manual mill, i still need a tool length, correct?
[04:25:22] <fluffybitchx> I _hate_ lazyloading. find a plugin that breaks lazyloading on every site that uses it, so all images are loaded BEFORE you get to where they are, not after!
[04:25:34] <XXCoder> lol yeah there is onme
[04:25:39] <XXCoder> but only for one site
[04:26:06] <XXCoder> i tried it, didnt like it and removed lazy load images
[04:26:51] * fluffybitchx wonders if that test is the most popular thing ever cut with linuxcnc
[04:27:24] <fluffybitchx> with lazyloading, you scroll down, then there's an empty box where the image should be... then you have to wait for it to load. with sane loading, by the time you scroll down to the image, it's already loaded, so you don't have to wait for it.
[04:28:27] <XXCoder> lazy lazy plugin does exactly that only for all sites
[04:28:33] <fluffybitchx> this mill is definitely not what I want for my long-term machine... but it does seem to work. I need to figure out how to get the lathe chuck off, because with it on, you only get 7.5" on throat depth, instead of the 11" you'd get without it.
[04:28:39] <XXCoder> I found tab stop load so I can just open lots tabs then stop all load
[04:28:45] <XXCoder> then load one a time. awesome
[04:28:52] <fluffybitchx> yes. which is the exact opposite of what I want. I want to never, ever be subjected to lazyloading.
[04:29:53] <fluffybitchx> 11x10x3 is not a particularly great cutting volume.
[04:30:15] <fluffybitchx> also, I found out my mt3 extension I got doesn't fit my spindle. I think I need to cut it shorter. it hits something before the taper seats.
[04:30:46] <fluffybitchx> I have 17" of X travel, but it doesn't do you any good when you only have 11" to the column!

[05:23:06] -!- zeeshan-mill [zeeshan-mill!~zeeshan@CPE0018e7cea342-CM5039555db2cc.cpe.net.cable.rogers.com] has joined #linuxcnc
[05:23:37] <LeelooMinai> And all the low bandwidth people were happy:)
[05:23:44] <fluffybitchx> even with no size info, it'll render the text before loading the images - it'll just re-flow the text when it gets the image headers.
[05:23:54] <fluffybitchx> lazyloading is entirely about saving server bandwidth
[05:24:14] <zeeshan-mill> got the encoder wired
[05:24:15] <zeeshan-mill> yay
[05:24:19] <zeeshan-mill> TEST TIME
[05:24:32] <Tom_itx> got 2 more boards din mounted
[05:24:34] <zeeshan-mill> what did i miss
[05:24:38] <zeeshan-mill> Tom_itx, what boards
[05:24:39] <LeelooMinai> Yes, it would render it, but not in the places it was intended too - it was a bit of a problem.
[05:24:46] <XXCoder> fluffybitch nah it does not do what I want. too bad
[05:24:48] <fluffybitchx> oh, on a mill-related topic... I've found my steppers make most excellent generators. a few cranks of the handwheels with the power supply off, and my caps rise to >20V!
[05:24:49] <Tom_itx> the isolation board and the C6
[05:25:02] <Tom_itx> i'm running out of room
[05:25:04] <fluffybitchx> zeeshan: http://fw.bushytails.net/milltest01.jpg
[05:25:05] <XXCoder> fluffybitchx: wind power :)
[05:25:29] <Tom_itx> i had to make the mounts for them though
[05:25:38] <zeeshan-mill> nice fluffy!!!
[05:25:43] <zeeshan-mill> that is bad ass
[05:25:51] <fluffybitchx> if I crank the handwheels, the voltage rises about the 18V cutoff of the drivers, then the drivers power up and lock the motors, so I can't crank them until the power supply discharges again...
[05:25:54] <LeelooMinai> fluffybitchx: I think those fluffy (sic) edges are because of low speed?
[05:26:23] <fluffybitchx> LeelooMinai: low speed, and the material chattering. I only clamped at the far end (just visible in the right of the image), and it was getting sucked up by the endmill.
[05:26:44] <LeelooMinai> RIght, bad clamping never ends well
[05:26:51] <fluffybitchx> that's also why it's deeper on one side than the other...
[05:27:30] <zeeshan-mill> hm
[05:27:34] <zeeshan-mill> index pulse not registering
[05:27:41] <zeeshan-mill> =[
[05:27:42] WalterN is now known as tiwake
[05:28:05] <fluffybitchx> homebuilt encoder or factory module?
[05:28:33] <zeeshan-mill> home built
[05:28:43] <zeeshan-mill> i noticed that even my linear encoders
[05:28:47] <fluffybitchx> check alignment of sensor and ring
[05:28:48] <zeeshan-mill> dont show an index pulse on the 7i77
[05:28:54] <zeeshan-mill> oh i know its working
[05:28:58] <zeeshan-mill> there are led's on the actual sensor
[05:29:06] <zeeshan-mill> it goes on and off through index
[05:29:15] <zeeshan-mill> trying to halscope it
[05:29:27] <fluffybitchx> ah
[05:29:48] <fluffybitchx> I need to build an encoder for my spindle... probably cut it with a tiny endmill from an aluminum disk.
[05:30:09] <fluffybitchx> someone else in here used countertop material, but I like metal.
[05:30:37] <zeeshan-mill> im dumb
[05:30:40] <zeeshan-mill> i was logging the wrong thing
[05:30:53] <XXCoder> can always grab el cheapo metal sheet from $12 store
[05:30:55] <XXCoder> mill it
[05:31:00] <XXCoder> er $1
[05:31:02] <fluffybitchx> no, you're only dumb if you come in here talking about how you blew another drive. :P
[05:31:12] <fluffybitchx> XXCoder: I like the local scrapyard.
[05:31:15] <zeeshan-mill> hahah
[05:31:22] <XXCoder> no scrapyard here too bad
[05:31:36] <LeelooMinai> What is the final count, 4 drives?
[05:31:45] <fluffybitchx> also, aluminum clipboards make most excellent material. :)
[05:31:58] <fluffybitchx> clipboards tend to be a good strong alloy
[05:32:06] <XXCoder> clipboards, one for hold paper stack with clip?
[05:32:24] <fluffybitchx> yep
[05:32:35] <XXCoder> ok had to be sure. never seen such lol
[05:32:41] <LeelooMinai> Not very thick though
[05:33:18] <fluffybitchx> LeelooMinai: plenty thick for an encoder disc!
[05:33:24] <fluffybitchx> XXCoder: https://d1t8ok2zesyvw2.cloudfront.net/spree/products/43/original/open-uri20130816-17199-3k7wy4.?1376685493
[05:33:34] <XXCoder> not bad
[05:33:39] <LeelooMinai> SO how much is such clipboard? :)
[05:33:45] <XXCoder> my bro saw one made from carbon fibre lol
[05:33:50] <XXCoder> its basically immortal
[05:34:00] <fluffybitchx> they're useful if you need a piece of metal and it's the weekend and all the non-big-box stores are closed...
[05:34:16] <LeelooMinai> It's probably not 6061-T6:)
[05:34:26] <fluffybitchx> LeelooMinai: a lot more than the per-sqft cost of the metal, but often less than the cut charges if you just want a little piece.
[05:37:11] <fluffybitchx> bbl, wolfy bedtime
[05:37:16] <XXCoder> night
[05:37:33] <zeeshan-mill> gnite
[05:38:06] <fluffybitchx> my mill is nowhere near done, but making chips is encouraging.
[05:38:13] <XXCoder> I bet yes

[08:13:08] <zeeshan> i just realized i made a big mistake :/
[08:13:22] <zeeshan> i accidently put the a and b phase 180 degrees apart physically
[08:13:23] <zeeshan> fak!
[08:14:39] <Crom_> mdf is crap for taking screws

[08:15:06] <zeeshan> fak, i really hope pcw has a solution

[08:15:18] <zeeshan> that allows me to offset the wave
[08:15:26] <zeeshan> you mean 90

[08:15:51] <zeeshan> index pulse
[08:15:51] <Jymmm> MDF will actually thread on the sirface, you just can't go thru an edge.
[08:16:49] <Crom_> B will be on the index if you shift 90 degrees
[08:17:42] <Crom_> that's my problem to turn 90 degrees on MDF you have to go through an edge
[08:18:10] <Crom_> delrin will work much better
[08:19:35] <Crom_> crap now I have to get another end mill 3/32" for making holes a 1/8" screw will thread into

[08:36:13] <Crom_> when I get mine running I guess I'll hack off the space's spindle mount and rig a new one which is tramable and changable
[08:36:55] <Crom_> then do the same to mine. Spindle,extruder, wood burner (Not laser)

[15:22:47] <fluffybitchx> suggestions for motor connectors? something that can handle 10A/phase.
[15:23:16] <fluffybitchx> I was going to use anderson powerpoles, rated for 30A, but they're not shielded...
[15:24:14] <cpresser> fluffybitchx: XLR might do
[15:25:36] <fluffybitchx> I don't know if they can reliably handle 10A... I know the ones used on wheelchair chargers have an annoying habit of melting.
[15:25:42] <archivist> direct wire for reliability
[15:26:58] -!- BellinganRoy has quit [Quit: Konversation terminated!]
[15:27:48] <cpresser> fluffybitchx: the 3-pin version does 16Amp according to the datasheet
[15:28:01] <fluffybitchx> I thought about that, but it's not great for maintainability... especially since I have to dismantle the mill to easily move it.
[15:29:08] <cpresser> http://www.neutrik.de/de-de/xlr/dl-serie/nc4fd-l-b-1
[15:29:18] <cpresser> rated for 10A
[15:29:44] <SpeedEvil> You don't really need to shield the motor drive wires
[15:29:51] <SpeedEvil> if you shield the signal ones
[15:30:49] <pcw_home> twisting the wires (pair per step motor winding) reduces the radiated EMI
[15:31:06] <fluffybitchx> I'm shielding BOTH. belt and braces, etc.

[15:48:06] <cpresser> yep, they are easy to source
[15:48:16] <fluffybitchx> plus I probably have a dozen of them in a box somewhere...
[15:48:24] <archivist> compatible does not mean 10a capable
[15:48:53] <fluffybitchx> although I think I only have 3 and 5 pin, no 4 pin.
[15:49:02] <archivist> they were designed for audio
[15:50:19] <fluffybitchx> grrrr. searching on ebay is now annoyingly difficult thanks to their new "feature" of hiding the item description.
[15:51:50] <fluffybitchx> I probably should use 5-pin xlr instead of 4-pin, and just not use a pin, due to their much wider availability.

[17:02:57] <fluffybitchx> if it smokes the driver too, I'll be rather annoyed.
[17:03:00] <XXCoder> so you grind chinese crap that released magic smoke to powder and smoke it? but magic smokes gone! ;)

[17:22:16] <_methods> i'm going to copy theirs except i'm going to use linear ways
[17:22:22] <tjb1> built my plasma using their linear bearing things
[17:22:23] <JT-Shop> it's colder inside than outside...
[17:22:30] * JT-Shop goes to open the shop doors
[17:22:34] <XXCoder> due to your heat JT-Shop ;)
[17:22:40] <XXCoder> er heart
[17:23:05] <fluffybitchx> I've been thinking of making a very cheap 4x8 setup using stainless steel cable for the drive...
[17:23:07] <tjb1> holy cow, its 22F here
[17:23:12] <fluffybitchx> and standard angle iron for the rails
[17:23:21] <_methods> i'll be building my plasma based on thier design with hiwin linear ways
[17:23:43] <JT-Shop> it says it it 47F here but feels a lot warmer out in the sun
[17:23:45] <fluffybitchx> of course, I still don't know if my plasma cutter even works. lol
[17:24:13] <CaptHindsight> 7F, back to -10F again tonight

[17:25:14] <fluffybitchx> aluminum extrusions are shiny and all, but I think for a plasma table, I'll be perfectly happy welding together some scrapyard angle iron.

[17:25:41] <tjb1> was that done by hand?

[17:28:48] <XXCoder> have fun
[17:29:00] <tjb1> I built 7 of those
[17:29:05] <tjb1> bearing blocks that is
[17:29:10] <tjb1> will just buy them next time
[17:29:21] <tjb1> very tedious on a bridgeport
[17:29:42] <CaptHindsight> I've never seen so many carriage bolts used in a design
[17:30:00] <XXCoder> rigid thats for sure
[17:30:04] <fluffybitchx> too fancy. I'm going to use V-grooved wheels riding on upwards (like ^) facing angle iron, held together with gravity, moved by steel cable. heh.
[17:30:04] <CaptHindsight> yes for $10ea
[17:30:15] <tjb1> CaptHindsight: Have you ever priced the t-slot bolts?

[17:34:55] <XXCoder> really bad review on 4x8 version

[18:02:12] <XXCoder> okay making sure that I used right word - "fence" is the strip of metal that wood slide on in order to make cut stright
[18:02:23] <XXCoder> theres other item that pushes wood part
[18:02:38] <_methods> that's a kickback guard
[18:02:46] <_methods> well should be
[18:02:55] <_methods> i remove those as soon as i get a saw lol
[18:02:59] <XXCoder> kickback guard is thin strip being saw
[18:03:00] <tjb1> zeeshan: this is the only power supply like this I could find that can supply 10amp at 12v
[18:03:02] <XXCoder> *behind
[18:03:03] <tjb1> probably why...
[18:03:15] <XXCoder> it keeps cut wood away from saw
[18:03:26] <_methods> hmm i have no idea what that is then
[18:03:54] <_methods> well some cheap saws will have no way to adjust the fence to cut square
[18:03:58] <XXCoder> nice http://www.rockler.com/how-to/table-terminology/
[18:04:12] <XXCoder> and yeah fence is correct :)
[18:04:19] <XXCoder> yeah el cheapo saw here
[18:04:28] <zeeshan> meanwell's s-150
[18:04:30] <zeeshan> does 12.5A
[18:04:30] <XXCoder> probably will make jig something
[18:04:33] <_methods> ah you may be screwed then
[18:05:45] <XXCoder> yeah quite crappy table saw lol

[18:06:35] <XXCoder> https://woodgears.ca/delta_saw/sled.html
[18:06:35] <tjb1> dont have eanywhere to mount that thing
[18:06:55] <tjb1> superglue on transformer bad?
[18:08:06] <_methods> yes a crosscut sled is good for making sure you're square
[18:08:18] <XXCoder> small version https://woodgears.ca/delta_saw/small_sled.html
[18:08:22] <_methods> but you can only rip the sleds length
[18:08:40] <XXCoder> not quite, the large one is shown cutting 8 feet long board
[18:08:57] <_methods> yes crosscutting
[18:09:07] <zeeshan> tjb1: you can't really fix it
[18:09:14] <zeeshan> unless you take the transformer apart and rewind it :P
[18:09:20] <XXCoder> gonna figure how to build it though, because fence sucks
[18:09:35] <zeeshan> the windings are likely vibrating with each other
[18:09:39] <XXCoder> its more accurate to have sled then build cnc parts with it
[18:09:53] <_methods> http://www.deltamachinery.com/accessories/biesemeyer
[18:10:29] <zeeshan> try superglue! :P

[19:10:55] <zeeshan-mill> !
[19:11:25] <zeeshan-mill> the on state that i want is longer
[19:11:27] <zeeshan-mill> than the off state
[19:13:33] <zeeshan-mill> pcw_home, can i wire to /A /B /INDX
[19:13:38] <zeeshan-mill> to invert
[19:13:41] <zeeshan-mill> i mean /A /B
[19:13:44] <zeeshan-mill> index is fine
[19:14:37] <pcw_home> Only if you have differential (line driver) outputs available (you swap pins to change polarity)
[19:14:58] <zeeshan-mill> i dont have differential output
[19:15:19] <zeeshan-mill> is there no way to invert it in the software
[19:15:59] <pcw_home> Theres typically no need to invert
[19:16:03] <zeeshan-mill> http://i.imgur.com/XpsuNRD.png
[19:16:08] <zeeshan-mill> you can see my off state is longer
[19:16:10] <zeeshan-mill> than my on state
[19:16:28] <pcw_home> inversion wont help that
[19:16:32] <zeeshan-mill> oh
[19:16:48] <zeeshan-mill> i really dont know why im getting varying pulse widths
[19:16:53] <zeeshan-mill> the wheel looks clean and fine
[19:17:04] <pcw_home> they should be as symmetrical as possible
[19:17:12] -!- moorbo has quit [Ping timeout: 250 seconds]
[19:17:45] <pcw_home> it has to do with the threshold of the light reciever
[19:18:26] <pcw_home> the light intensity will be roughly sinusoidal
[19:19:10] <pcw_home> depending on the receiver threshold you can get <50% or >50% duty cycle
[19:19:38] <zeeshan-mill> my physical wheel has a longer on period
[19:19:39] <zeeshan-mill> than off
[19:19:50] <zeeshan-mill> when light passes through = on
[19:19:56] <zeeshan-mill> but its inverted in linuxcnc
[19:20:07] <zeeshan-mill> but i guess youre saying that wont change anything
[19:20:12] <zeeshan-mill> i shoulda made my wheel symmetric to begin with
[19:20:37] <CaptHindsight> do they sense the reflections off each tooth or do the teeth block the light?
[19:20:38] <pcw_home> can you change the LED current?

[19:22:09] <pcw_home> Ha!
[19:22:12] <zeeshan-mill> lol
[19:22:23] <zeeshan-mill> CaptHindsight, the teeth block light
[19:22:38] <zeeshan-mill> pcw_home, it takes 5v - 24v input
[19:22:52] <zeeshan-mill> i didnt see a mention of that effecting light intensity
[19:22:54] <zeeshan-mill> it prolly does
[19:23:05] <zeeshan-mill> but encoders only output 5v
[19:23:18] <CaptHindsight> try painting the teeth flat black as well
[19:23:19] <_methods> you could use something like an arduino to pwm the led
[19:23:50] <_methods> kludge but you could still test it out and get it working
[19:23:54] <pcw_home> you might experiment with a filter

[20:43:15] <witnit> I created an M150 command which calls a bash script and then lets gcode continue. While the gcode processes the rest of the file, my other pins are being handled through the second bash script called in this format; halcmd setp gpio.xx.out true; sleep 1; false exit; is this safe and or proper?
[20:47:00] <Connor> witnit What's this script for ?
[20:47:04] <witnit> i have some sequences i need automated while the rest of the program is running, since these can be both ran at the same time i can reduce my cycle time by about 30% im just not sure which is the best route
[20:48:16] <witnit> its a gate and debur station at 2 seconds, then gravity feeds a crossdrill at 4 sec stacking gcode is a 6 second job, but if i can debur while the drill is happening the part will be ready to drop when the old part gets out of the way
[20:48:45] <Connor> What is this for?
[20:48:52] <Connor> sounds interesting.
[20:49:00] <witnit> debur and crossdrill station
[20:49:16] <Connor> I say give it a shot. Sounds like it'll work.
[20:49:33] <witnit> it functions but i did know if there was a more proper way to do it
[20:49:54] <Connor> You could try remap and O code.. I'm not sure it would parallel like that though.

[21:57:44] <MrSunshine> XXCoder: tho i think its lupe im thinking of but... associations went far far away from what i guess you actualy ment :P
[21:58:10] <XXCoder> nah its loupe
[21:58:24] <XXCoder> https://www.google.com/search?q=lupe+l&safe=off&source=lnms&tbm=isch&sa=X&ei=48TfVMn3GM33oATkroKADw&ved=0CAoQ_AUoAw&biw=1920&bih=969#safe=off&tbm=isch&q=loupe
[21:58:37] <XXCoder> lupe is mostly pics of ladies
[21:58:51] <XXCoder> or guys
[21:59:25] <XXCoder> also furry wolf charactor of some kind
[21:59:38] <MrSunshine> XXCoder: yes ... the word was correct but I thought about "lupe" when i read it :P
[21:59:45] <XXCoder> oh
[21:59:59] <XXCoder> lots possibilities on what your lupe is
[22:00:14] <MrSunshine> adult actress ...
[22:00:15] <MrSunshine> :PÖ
[22:00:21] <XXCoder> lol ok
[22:00:26] <XXCoder> pornfistic
[22:01:03] * MrSunshine tried to open his pcv valve canal today with a piece of steel cable ...
[22:01:14] <MrSunshine> went good and all .. until it got like 2cm shorter in a hurry
[22:01:44] <MrSunshine> so i got two options... 1 ... the cable tore off in the canal and i now run the risk of getting steel cable into one of the cylinders of the car ...
[22:01:55] <MrSunshine> 2 ... the wire twisted up and got shorter due to that .. it got 3 tight spots ...
[22:02:41] <XXCoder> its likely more than one chip died, some resistors around it dont look good
[22:03:18] <XXCoder> no loss, friend of mine already had replacement shipped

[22:17:26] <zeeshan-mill> pcw_home, if my trigger wheel has 1 weird tooth
[22:17:31] <zeeshan-mill> will this affect anything
[22:17:47] <XXCoder> maybe if bigger
[22:17:50] <XXCoder> smaller maybe not?
[22:18:15] <XXCoder> is it critical that gears mesh perfectly?
[22:18:25] <zeeshan-mill> its not meshing with anything
[22:18:38] <pcw_home> as long as quadrature is not violated. it will count correctly
[22:18:40] <XXCoder> ah was thinking "gear"
[22:18:58] <pcw_home> but may have a velocity glitch at that point
[22:19:25] -!- FreezingAlt [FreezingAlt!~FreezingC@135.0.41.14] has joined #linuxcnc
[22:19:28] <zeeshan-mill> it will likely violate quadrature :/
[22:19:53] <pcw_home> then it will not count correctly
[22:19:55] <zeeshan-mill> i guess im remachining this
[22:19:59] <zeeshan-mill> down to 25 teeth lol
[22:20:25] <XXCoder> wild guess, more teeth = more accuratre?
[22:20:33] <zeeshan-mill> ya
[22:20:44] <XXCoder> 1,000 teeth ;)
[22:20:47] <zeeshan-mill> if your photointerruptors can keep up
[22:21:21] <XXCoder> yeah 1,000 would nee very good sensor I bet
[22:21:35] <Tom_itx> zeeshan for the spindle?
[22:22:01] <zeeshan-mill> yea
[22:22:16] <Tom_itx> what about mounting?
[22:22:24] <zeeshan-mill> do the teeth have to be even
[22:22:25] <zeeshan-mill> like
[22:22:34] <zeeshan-mill> the amount of time of light blocked
[22:22:44] <Tom_itx> it would probably be best
[22:22:45] <zeeshan-mill> to the amount of time of thru light
[22:22:52] -!- FreezingCold has quit [Ping timeout: 240 seconds]
[22:22:58] <zeeshan-mill> mounting isnt a prob
[22:22:58] <Tom_itx> get a real encoder for it?
[22:23:04] <zeeshan-mill> no
[22:23:07] <zeeshan-mill> im almost there
[22:23:12] <zeeshan-mill> why would i get a real encoder :P
[22:23:12] <pcw_home> 25 teeth is 100 counts/turn so say a 1/4-20 tap would have 1/2000 inch Z steps
[22:23:26] <Tom_itx> i've got several HEDS ones but i'm using another type with 500 cpr 2000 quad
[22:23:36] <zeeshan-mill> ill stick to 50 teeth

[22:23:47] <XXCoder> what kind material?
[22:23:49] <pcw_home> old CD
[22:23:50] <zeeshan-mill> the index mark didnt line p with where i machined
[22:23:51] <ssi> hi

[22:24:01] <zeeshan-mill> excellent idea pcw!

[22:24:03] <ssi> what's shakin
[22:24:06] <zeeshan-mill> hi
[22:24:16] <XXCoder> zeeshan-mill: just go to dollar store
[22:24:22] <XXCoder> grab some $1 metal pan
[22:24:25] <Tom_itx> CDs are brittle
[22:24:37] <Tom_itx> but would probably work

[22:56:26] <XXCoder> nice
[22:56:39] <zeeshan-mill> hopefully frosting the acrylic
[22:56:41] <zeeshan-mill> will stop light

[23:16:03] <XXCoder> lemme calulate that
