[03:04:38] <Kineng64> Anyone on here tonight, looking for some help with a spindle controller card
[03:05:59] <XXCoder> hey
[03:06:05] <XXCoder> here but unfortuntaley I dont know that
[03:06:14] <XXCoder> ask away though
[03:06:25] -!- jthornton has quit [Read error: Connection reset by peer]
[03:07:20] <Kineng64> Basically I have a 0-10V card that is old and uses step pulses instead of a PWM. I have the code from the manufacture but it keep failing on this line: loadrt stepgen step_type=0,0,0,0,0 ctrl_type=p,p,p,p,v
[03:07:30] <Kineng64> If anyone has any ideas any help would be appreciated!!

[03:12:56] <Kineng64> Ya I am waiting on a Mesa 5i and thought I would learn a little bit about what I was getting myself into as I'm not a native linux user.
[03:13:29] <Kineng64> It's connected as a single parallel port to a very simple bob to the analog voltage card
[03:14:29] <Tom_itx> i've only done the adc on the mesa cards for my sherline spindle which is also 0-10v instead of the industry standard +-10v
[03:15:04] <Tom_itx> i used a 7I47S for it iirc
[03:15:22] -!- PetefromTn_ has quit [Quit: I'm Outta here!!]
[03:16:00] <Kineng64> That's what I'm noticing is this card I'm using is very old and doesn't use the new ways of controlling things. How do you like the Mesa products?
[03:16:12] <Tom_itx> they're good
[03:17:18] <Kineng64> Good deal, I think maybe I will just wait for mine to show up and start fresh. Really looking forward to Linuxcnc though, Mach has destroyed one too many customer parts!

[03:18:05] <Tom_itx> linuxcnc runs pretty well
[03:18:16] <Tom_itx> very flexible
[03:18:29] <Tom_itx> little bit of a learning curve to it but it works good

[03:20:17] <Kineng64> That's what I've read, and my PathPilot controller for my PCNC1100 works great, I'm noticing the learning curve though. seems with more flexibility you get more of a learning curve

[03:22:04] <Tom_itx> you can start with their pncconfig but you will end up configuring it manually to tweak it the way you want it

[05:27:59] <XXCoder> its OVERFLOWING
[05:28:38] <yasnak> Sorry. I'm not sure if I know what you're saying
[05:29:28] <XXCoder> I'm saying that it is worse than "full retard"
[05:30:08] <XXCoder> poticitians are pouring retard into container and its full and they don't stop, and its spilling everywhere and they dont stop
[05:30:47] <yasnak> So what the hell is wrong with the population?
[05:31:02] <XXCoder> lack of education
[05:31:15] <XXCoder> there has been constant school budget cuts.
[05:31:17] <yasnak> I saw trump say to ban apple products? Are you kidding me?
[05:31:25] <XXCoder> trump the rump
[05:31:58] <yasnak> I'd invest my money in iphone if I knew the govenmnet would play nice. But they won't. They will get their way and it won't be fair. Apple is essentially in a no-win situation :?
[05:32:04] <yasnak> All of us...
[05:33:10] <XXCoder> I hate apple but they are actually fighting the good fight for privacy
[05:34:02] <yasnak> The sad part is that they admit the NSA already has many zero days they could have used but the FBI totally botched the entire thing

[09:08:44] <felixi> AAAARARARARA. Cython seems like phun. Delays the need to actually need to know c++
[09:08:56] <felixi> who would want to code c++? :D
[09:09:12] <XXCoder> c++ is a messy beast on top of C
[09:09:17] <XXCoder> c++ compiles to C
[09:09:19] <felixi> i think alike
[09:09:21] <felixi> :D
[09:10:55] -!- mike__ has quit [Ping timeout: 246 seconds]
[09:14:08] <Ralith> C++ doesn't compile to C any more than any native language does...
[09:14:34] <XXCoder> Ralith: it does. then it compiles C to normal binary
[09:14:55] <felixi> no no. it compiles to asm and then binary. doesnt it?
[09:15:01] <Ralith> XXCoder: no, that isn't even remotely how present-day compilers work
[09:15:14] <Ralith> I am a compiler engineer. This is my profession.
[09:15:25] <XXCoder> I'd say no, but then my knowledge may be behind
[09:15:44] <XXCoder> cool then
[09:15:53] <Ralith> your knowledge is two decades behind, or more :P
[09:15:59] <XXCoder> so it compiles direct now
[09:16:09] <XXCoder> I'd say 10+ years by now?
[09:16:37] <Ralith> compilation is a process of successive transformations, but C has not been involved in any major toolchain for quite some time
[09:16:59] <XXCoder> heh I only wrote one compiler, as part of college assignment
[09:17:07] <XXCoder> turtle script interpeter
[09:17:09] <Ralith> very few languges are so simple that you can actually go directly to machine code and C++ is certainly not one of them
[09:17:23] <felixi> i only read part of the dragon book for phun
[09:17:26] <felixi> :D
[09:17:54] <Ralith> (you might have been fuzzy on the implementation details but you're certainly right about it being a messy beast)
[09:17:59] <Ralith> (albeit a frequently useful one)
[09:18:22] <XXCoder> yeah I wrote ldraw to dxf converter on c++ at one point
[09:18:31] <XXCoder> earliest version was done in vb5 lol
[09:18:35] <Ralith> modern C++, most significantly as of the C++11 standard, has also changed quite a bit for the better
[09:18:41] <XXCoder> nice
[09:18:52] <felixi> Ralith: how?
[09:19:14] <Ralith> far less boilerplate and hazardous manual pointer juggling, richer ownership semantics
[09:19:34] <Ralith> richer constructs for compile-time computation
[09:20:14] <XXCoder> does it still using pointers?
[09:20:20] <XXCoder> sometimes such abuse is useful
[09:20:39] <Ralith> they're certainly available, but you're encouraged to avoid them where they're not specifically necessary
[09:21:11] <XXCoder> I remember making a union of a 64 bit int, so i could access it as 2 32 bit values, or 8 8 bit int lol
[09:21:21] <XXCoder> fun with unions
[09:21:21] -!- ybon has quit [Ping timeout: 268 seconds]
[09:21:30] <Ralith> that is not actually legal per the standard
[09:21:44] <Ralith> (well, it's legal, but the effects are undefined)
[09:22:29] <Ralith> in most environments you can get away with it but you're encouraged to implement such semantics with bit shifts and similar instead
[09:22:36] <felixi> is an ebook reader better for raeding books than a tablet?
[09:22:39] <XXCoder> hmm always thought union use was for that
[09:22:47] <XXCoder> felixi: WAAAAY better
[09:22:53] <Ralith> unions are for saving space, not for punning
[09:22:55] <felixi> XXCoder: you have exp? How?
[09:23:03] <Ralith> I concur, I'm very happy with my Kindle Paperwhite
[09:23:07] <felixi> XXCoder: i want a reader or a pad specifically for reading ebooks
[09:23:11] <XXCoder> felixi: its like reading paper so your eyes dont get too tired
[09:23:13] <felixi> i dont need or want pad otherwise really
[09:23:17] <Ralith> also, the batteries last absolutely forever
[09:23:24] <Ralith> and they're extra lightweight
[09:23:28] <XXCoder> I own kindle, and older NST and even older nook orginial
[09:23:37] <XXCoder> Ralith: it lasts 2 weeks for me lol
[09:23:41] <Ralith> well

[09:24:56] <Ralith> hm
[09:25:13] <Ralith> there are some features for hilighting passages and writing margin notes and stuff
[09:25:15] <XXCoder> good question as mine is mostly science fiction or fantasy
[09:25:16] <Ralith> might do what you want
[09:25:30] <XXCoder> fantasy isnt my forte but its hard to find book I havent read.
[09:25:44] <XXCoder> indeed
[09:25:50] <XXCoder> bookmarks, highlights, and notes.
[09:25:58] <Ralith> amazon's selling them pretty cheap these days, so it doesn't need a ton of agonizing over imo
[09:26:10] <XXCoder> or buy used nst or something, $40
[09:26:17] <XXCoder> see if you like ebook style display
[09:26:32] <XXCoder> but then kindle pw3 is around $120 if you want no ad version
[09:27:12] <archivist> cant beat read dead trees for reference books
[09:27:34] <Ralith> I actually favor PDFs on a laptop for reference books

[09:28:53] <archivist> here is a rare thing two zoomable views into one doc http://www.collection.archivist.info/diva/systrondonner1626.html#p=127&z=1
[09:28:58] <yasnak> I think its mainly because I do most my learning via toilet seat. My phone is a pain with PDF's
[09:29:01] <XXCoder> thats if pdf isnt just series of crappy pictures

[09:29:49] <felixi> http://www.pocketbook-int.com/us/products/pocketbook-color-lux
[09:29:51] <felixi> this one has colours
[09:30:00] <XXCoder> pdf is good standard if you want files to be useable for long time
[09:30:13] <XXCoder> but not if its badly done, like just batch of large pictures
[09:30:18] <Ralith> you probably do not want colors
[09:30:26] <XXCoder> you dont want colors indeed
[09:30:34] <felixi> its supposed to be e-ink or something
[09:30:37] <felixi> not lcd
[09:30:44] <XXCoder> HMM
[09:30:46] <Ralith> nonetheless it will cost more and have inferior contrast and resolution and software
[09:30:51] <XXCoder> thats new

[15:17:13] <newbie25174> hello
[15:17:26] <zeeshan|2> hi
[15:18:29] <newbie25174> I'm looking for a drill bit
[15:20:00] <yasnak> uh
[15:20:08] <yasnak> not sure drill bit is online, might be sleeping yet
[15:21:14] <newbie25174> I have 1/8" ZrO2 sphere that I need to drill about half the depth
[15:21:55] <newbie25174> what kind of a drill bit can handle that
[15:22:12] <archivist> grind
[15:22:15] <yasnak> Okay, so you're going to drill an 1/8 piece of it? I don't understand
[15:22:37] <zeeshan|2> daimond
[15:22:39] <zeeshan|2> diamond
[15:23:10] <newbie25174> and where I can get very small dimond drill bit...
[15:23:22] <archivist> burr
[15:23:52] <archivist> you can also use a diamond paste and copper
[15:24:29] <newbie25174> what is dimond paste?
[15:25:00] <archivist> powdered diamond dust in a lubricant
[15:25:22] <yasnak> harveytool.com
[15:25:32] <yasnak> but it won't be cheap
[15:26:26] <yasnak> I'd just use a POS carbide burr and see what happens. I've never cut ZrO2. The fact you think you can drill it makes me think you can at least burr it.
[15:27:01] -!- Daerist has quit [Quit: Leaving]
[15:27:05] <newbie25174> I want to make a tip for my probe.

[15:27:43] <yasnak> lol
[15:27:48] <yasnak> Why not just buy a tip man?

[15:32:13] <Sync_> yeah paste and copper probably works the best
[15:32:57] <Erant> I have a weird problem. My Z-axis has a little backlash that's variable with speed. Or more likely, acceleration. Higher speed, less backlash.
[15:33:24] <Erant> Difference of about 1.5 thou between moving the head @2.2IPM vs @20IPM
[15:33:51] <Erant> The only thing I can think of is some stiction issue, and the stronger jerk is overcoming it faster

[15:34:44] <Erant> _methods: I sort of figured. I might replace the gib with a brass one, see if that works better.
[15:35:03] <Erant> Or just take the current steel one out and polish it a little
[15:35:30] <archivist> pink_vampire, no
[15:35:41] <pink_vampire> :(
[15:36:01] <pink_vampire> archivist: do you know the brand name for it?
[15:36:03] <archivist> Erant, dont think brass is a normal cure
[15:37:16] <Erant> Huh. I'd always hear brass or delrin
[15:37:29] <Sync_> just scrape your current one
[15:37:32] <archivist> https://www.cousinsuk.com/category/abrasive-pastes
[15:37:51] <Sync_> or just use a ball bearing pink_vampire, they can be drilled with carbide with ease
[15:37:55] <yasnak> get some of the cylinder grinding compound from autozone
[15:38:00] <yasnak> works great and is cheap
[15:39:10] <Sync_> I'm not sure if it is hard enough for ZrO2
[15:40:01] <pink_vampire> archivist: I can't see anything about diamond, It's just say abrasive compound.

[16:07:19] <enleth> any suggestions for a relay/ladder logic/machine wiring schematic editor?
[16:08:00] -!- chris_99 has quit [Ping timeout: 276 seconds]
[16:08:10] <enleth> I'm rewiring the power relays in the bridgeport to hook the VFD into the relay logic properly and the factory schematic is going to go out of sync with reality
[16:08:40] <enleth> I can annotate some small changes with a pencil, but there are limits to this method
[16:09:29] <PetefromTn_> is this a linuxCNC retrofit?
[16:10:23] <enleth> yes, but I'm keeping most of the original relay logic
[16:10:32] <PetefromTn_> ah okay
[16:11:33] <enleth> the safety circuits are really well done and I'm going to trust them much more than any software
[16:12:09] <enleth> especially when it comes to cutting servo power on limit switches
[16:12:25] <enleth> and engaging brakes at the same time
[16:12:50] <PetefromTn_> when it comes to power on and off I agree
[16:12:58] <PetefromTn_> my machine is setup similarly
[16:16:36] <enleth> basically there is a chain of limit switches, overload switches and thermostats in various places that have to agree for the main feed contactor to remain closed
[16:16:58] <Jymmmm> Your machine shuld be in a crate and on a trailer goin to florida!
[16:17:16] <enleth> that in turn controls the brake relays
[16:17:33] <enleth> *and* feeds power to the servo drive
[16:17:43] WalterN is now known as tiwake
[16:18:18] <enleth> I'm not changing that, but I am rewiring the contactors that powered the spindle motor, so that they instead signal the VFD to run
[16:19:02] <enleth> *and* pass the VFD's "motor running" signal to the logic that controls VariSpeed
[16:20:47] <enleth> I can rewire it just fine and probably remember most of that for a few weeks
[16:21:47] <enleth> but I fear I'll start forgetting the details in a few months and problems will crop up when I start using the original schematic
[16:22:03] <duc> Notebook or PowerPoint can be used in a pinch
[16:22:09] <PetefromTn_> yup mine is setup the same way, limits, estop, etc are trips for main power contactors for the drives and spindle motor... And it is getting packed up this coming week.. for its trip to florida
[16:22:43] <PetefromTn_> I made a schematic diagram in draftsight showing the whole wiring scheme...
[16:23:21] <PetefromTn_> it is kind of a block diagram with small blow up circles with specifics inside them for wiring
[16:23:39] <PetefromTn_> the same scheme is getting used on the CNC lathe

[16:26:59] <tiwake> well
[16:27:17] <tiwake> my black shoe leather dye sucks for some reason
[16:28:05] <Jymmmm> tiwake: Just use spray paint ;)
[16:28:19] <tiwake> for anodizing? heh
[16:28:26] <Jymmmm> lol
[16:28:47] Jymmmm is now known as Jymmm
[16:28:59] <Jymmm> why would you use ax based for annodizing?

[16:31:01] <Jymmm> Fine, use a sharpie marker then =)
[16:31:58] <tiwake> did some anodizing last night and the parts when dyed with the leather dye came out splotchy
[16:32:25] <tiwake> put the others in the casswell black dye (water based) and it was fine
[16:32:53] <Jymmm> Did you use anti-splotchy leather dye?
[16:33:00] <enleth> PetefromTn_: do you have the schematic screenshot online?
[16:36:00] <tiwake> this is the dye I used http://www.amazon.com/Fiebings-Leather-Dye-Black-4oz/dp/B000HHM20M/ref=sr_1_1
[16:43:05] <DRGray> i realy struggled with anodising
[16:43:31] <DRGray> is that leather dye good?
[16:44:32] <DRGray> i think i have some caswell die but ive strugged to get good results
[16:46:01] <tiwake> DRGray: donno, I do know I anodize longer than suggested and I'm getting really good colors
[16:46:13] <Jymmm> tiwake: NFC, but... http://www.usspecialty.com/product.php
[16:46:27] <DRGray> with the casswell or the leather dye?
[16:46:38] <tiwake> DRGray: casswell dye
[16:46:45] <DRGray> yeah
[16:46:58] <DRGray> do you use much dye? does it go a long way?
[16:47:37] <tiwake> I have some dye coming from where CaptHindsight works... but not black because they are dumb and don't have black
[16:47:54] <Jymmm> tiwake: http://www.usspecialty.com/color.php
[16:48:03] <tiwake> Jymmm: I see :P
[16:48:37] <tiwake> Jymmm: are those solvent based or water based?
[16:48:39] <DRGray> 120ml = £47 doesnt seem like a lot of dye for the money
[16:49:01] <Jymmm> tiwake: 2016-02-28.08:46:13 Jymmm: tiwake: NFC, but... http://www.usspecialty.com/product.php
[16:49:19] <rob_h> they are clariant dyes, water they sell very very good
[16:49:28] <Jymmm> tiwake: NFC = No Fucking Clue ;)
[16:49:37] <tiwake> oh
[16:50:32] <tiwake> Jymmm: looks like its water based
[16:50:35] <tiwake> meh
[16:50:43] <tiwake> I kind of want solvent based :P
[16:50:54] <rob_h> y?
[16:51:02] <tiwake> cause I'm lazy and don't want to heat up the water bath

[16:53:10] <rob_h> and colours wount be as rich
[16:53:14] <tiwake> yeah
[16:53:35] <tiwake> for some reason my casswell purple and blue stick to the parts really really well and don't need heating
[16:53:42] <rob_h> need air aggregation too keeps it well mixed
[16:54:14] <rob_h> black is probly the worst colour to keep deep and rich black... and more fussy on poor size
[16:54:29] <rob_h> pore
[16:54:44] <tiwake> thats what I've heard
[16:55:04] <rob_h> i run 12 ASF tho
[16:55:15] <tiwake> ASF?
[16:55:29] <rob_h> amps per squarefoot
[16:55:44] <Jymmm> @ 440V
[16:56:00] <rob_h> anodizing tends ot be around 15/16v
[16:56:05] <tiwake> been running about 4ish amps
[16:56:11] <rob_h> depends on racks etc.. if Ti racks need add volt
[16:56:33] <rob_h> but i never anodizing to volts only CC
[16:56:33] <tiwake> with voltage typically popping out at 12-14
[16:57:10] <rob_h> i found power supplies make a big differance too if they are not real CC things get hard fast
[16:57:32] <tiwake> yeah, I have a good constant current power supply :3

[16:58:15] <rob_h> i have somealli jigs but use very rare... for spehsial parts that dont fit Ti
[16:58:31] <rob_h> or i use Alli wire 1.5mm/2mm welding wire works realy well
[16:58:48] <rob_h> and just cut it off part when done etc
[16:59:05] <tiwake> thats what I'm running into, using aluminum (electrical fence) wire to hang parts in
[16:59:13] <tiwake> pain in the butt
[16:59:16] <rob_h> if in US your lucky these guys have good prices i found for racks.. and in stock. http://www.anodizingracksonline.com
[16:59:53] <tiwake> I also need to get an acid pump to keep the liquid moving
[17:00:53] <rob_h> just run a good air aggregation pipe in acid tank stop part burning and keep it moving id not pump it around gets messy
[17:01:50] <rob_h> i would only pump for cooling if indirect cooling
[17:02:12] <tiwake> but air would make the acid kind of splatter everywhere

[17:05:22] <tiwake> probably going to fill it up on monday
[17:06:19] <rob_h> then you will want bigger
[17:07:27] <tiwake> rob_h: how do you check to make sure your acid bath keeps the correct amount of acid/water?
[17:07:38] <rob_h> its only water than evaps
[17:07:40] <rob_h> that
[17:07:54] <tiwake> mostly, but not quite
[17:07:56] <rob_h> over a very long time yes u will get drag out
[17:08:03] <tiwake> some acid leaves when you pull the parts out
[17:08:19] <tiwake> heh, not much, but it does a little

[17:10:29] <tiwake> flying leads?

[17:13:35] <rob_h> and cast form so will not anodizing well at all
[17:13:46] <tiwake> did my pocket knife handle a while ago
[17:14:02] <DRGray> my croc clips disintegrate
[17:14:24] <tiwake> rob_h: yeah, I'd imagine that cast aluminum won't anodize very well
[17:14:34] <rob_h> most not at all
[17:14:49] <rob_h> thoes that do have to mess around with them and pre etch/ and other nasty things

[17:20:41] <DRGray> and improve my patience
[17:20:58] <tiwake> solvent based dye is really nice for that

[17:24:10] <rob_h> whats that 62f for the US guys
[17:24:22] <DRGray> 17c is sort of workshop room tempreture
[17:24:27] <rob_h> too cold and pore are too small
[17:24:35] <rob_h> too hot and pore too big and part burn is easyer
[17:24:58] <tiwake> that happened to me once
[17:25:35] <tiwake> anodized too long and the part looked like it was dried up, like a raisin
[17:25:37] <DRGray> il give it another go this week i need to get it set up again, where i’ve been doing it sounds to cold its an outside shed.
[17:26:05] <tiwake> I think if you lower your current density that it will increase your pore size too
[17:26:24] <rob_h> just take longer
[17:26:34] <rob_h> but less heat made
[17:26:40] <tiwake> maybe 2-3 amps/ft^2
[17:26:47] <rob_h> why casewell do 7asf i think it is and not the common 12
[17:26:58] <tiwake> I run at 4-5 amps/ft^2

[17:27:12] <DRGray> what voltage?
[17:27:30] <tiwake> DRGray: constant current, so whatever the voltage pops out at
[17:27:40] <rob_h> clariant dyes for all
[17:27:49] <DRGray> what sort of power supply do you use?
[17:27:58] <tiwake> a bench power supply
[17:27:58] <rob_h> its a CC 3phase in
[17:28:05] <rob_h> 24v max out 500amp
[17:28:10] <tiwake> woah
[17:28:15] <tiwake> thats a serious power supply
[17:28:16] <tiwake> lol
[17:28:23] <tiwake> three phase
[17:28:24] <tiwake> ha
[17:28:24] <rob_h> well babby compared to a plating shop
[17:28:33] <rob_h> yea 3phase at home is nice as well as at work i guess
[17:29:03] <rob_h> iv used bench before but some not work grate others work very well
[17:29:27] <tiwake> I just have a 50amp max, 15-16 volt max bench power supply, I think it cost about $200
[17:29:28] <rob_h> i did or still do have two old ex mill bench power supplies 40amp out, 40v out
[17:29:59] <rob_h> but they have a fault and i think its output transister stack i go tthe parts but never had time to fix.
[17:30:32] <tiwake> if it goes above 15amps it switches over to constant voltage
[17:30:35] <DRGray> i have a desk top psu variable but i think it onyly does about 3 amps
[17:30:36] <tiwake> erm
[17:30:41] <DRGray> bit rubbish i guess
[17:30:43] <tiwake> above 15 volts rather
[17:30:57] <rob_h> depends what you doing
[17:31:07] <rob_h> not very CNC this chat lol
[17:31:07] <DRGray> i have 24-40 volt one, but it has some sort of protector in it
[17:31:11] <tiwake> DRGray: you need something that does constant current
[17:31:15] <DRGray> so it cuts out if you try and use it for anodising
[17:31:44] <rob_h> i think we all need to go make some parts to think about anodizing now
[17:32:04] <DRGray> parts that get made need colouring :-)
[17:32:17] <rob_h> indeed

[17:37:26] <DRGray> 30v 5 amp to low?
[17:37:50] <archivist> amps depends on area to be anodised
[17:38:06] <rob_h> take your biggest part you want anodizing work out amps
[17:38:10] <rob_h> add abit of head room
[17:38:39] <rob_h> most power supplies dont like working maxed out for long times tend to over heat
[17:39:52] <DRGray> http://www.shadowguarddev.com/alex/anodizing/
[17:39:59] <DRGray> Many people use automotive battery chargers to anodize;
[17:40:02] <DRGray> i have plenty of these
[17:40:31] <rob_h> just have control the output

[18:04:10] <CaptHindsight> DRGray: you need particles much smaller than the pores, so <20nm
[18:04:27] <CaptHindsight> thats why dyes are used vs pigments
[18:04:45] <CaptHindsight> dyes are in solution, particles are in suspension
[18:05:41] <CaptHindsight> you can use particles or pigments but they need to be milled down to <20nm for aluminum
[18:06:52] <DRGray> yeah
[18:07:04] <DRGray> i did buy some die for aluminium
[18:07:12] <CaptHindsight> tiwake: you don't need to dip an entire car to color it, the dye can be applied by spray
[18:07:14] <DRGray> but wasning getting consistant results
[18:07:48] <CaptHindsight> DRGray: thats where solvent dye comes in, it doesn't wash out when rinsed

[18:13:09] <CaptHindsight> it's apples and oranges for water vs solvent dye
[18:13:44] <archivist> uk http://gaterosplating.co.uk/Anodising-Dyes.php
[18:13:53] <CaptHindsight> the solvent dye is premixed and the only waste is what you might spill
[18:14:13] <CaptHindsight> or if you blend to much custom color and then not use it
[18:14:33] <DRGray> this is where i got my black dye from
[18:14:41] <CaptHindsight> water based you mix yourself and you have to tweak the bath
[18:15:06] <DRGray> yeah
[18:15:07] <archivist> the phone number is in my area!
[18:15:14] <DRGray> tweak ?
[18:15:52] <CaptHindsight> the big difference is when you require color that last more than a few years in direct sunlight
[18:16:19] <CaptHindsight> dye is easily broken down by UV
[18:16:47] <DRGray> yeah non of my stuff goes in the sun
[18:16:54] <CaptHindsight> so you need colorants that fit in the pores and don't easily break down when exposed to UV
[18:18:03] <CaptHindsight> there are also other things you can trap in the anodize like lubricants
[18:18:10] <DRGray> ill try again this week and be more methodical and patient see if i can get a some better results
[18:24:21] <DRGray> ok.. back to some cnc topics. on a stepper motor is a there a good guide pro/cons of not direct driving your stepper and putting it on a belt?
[18:25:07] <DRGray> also whats the best linux cad program?
[18:26:17] <Jymmm> DRGray: The one you create is the best of them all!
[18:26:22] <CaptHindsight> gearing
[18:26:54] <DRGray> improved torque, accuary
[18:27:01] <CaptHindsight> it's easy to get the ratio required with a belt
[18:27:04] <MrSunshine_> ough, hard to heat straighten when there is two points that its stuck to ... if i heat in one place it pivots it all in two places :P
[18:27:40] <DRGray> what are the normally things that make you want a speciffic ratio? more torque? more accuracy?
[18:27:43] <CaptHindsight> I have belts in positioners that have few arc seconds of repeatability
[18:28:07] <archivist> or what fits in the space
[18:31:46] <DRGray> thats pretty accurate
[18:32:42] <CaptHindsight> 61F bbl...
[18:33:06] <DRGray> CaptHindsight: what do you use your cnc for?
[18:36:33] <Erant> DRGray: I use gearing for my Z-axis servo because it has to lift the head, for example.
[18:36:44] <CaptHindsight> prototypes, custom machines, mechanisms....

[19:19:58] <archivist> cheaper to buy three separate drivers
[19:20:59] <DRGray> yes but sometimes its nice and neat
[19:22:00] <archivist> for me price and convenience of replacement
[19:22:26] <DRGray> yes i guess if one axis breaks you hae to replace the whole unit

[19:49:11] <CaptHindsight> I use them to save space and wiring time
[19:49:53] <CaptHindsight> I also integrate the driver into all-in-one touchscreen PC's
[19:52:37] <os1r1s> CaptHindsight Got a pic of that?
[19:52:58] <CaptHindsight> http://imagebin.ca/v/2YYZub4qizRP everything in the touchscreen
[19:53:14] <CaptHindsight> thats controlling a gantry robot
[19:53:26] <os1r1s> CaptHindsight What model screen is that?
[19:53:50] <CaptHindsight> one of the Acer's
[19:54:01] <CaptHindsight> multitouch version
[19:55:12] <os1r1s> CaptHindsight I had tried using an old elo, but it did not work well
[19:56:23] <CaptHindsight> http://www.newegg.com/Product/Product.aspx?Item=9SIA25V30N4519 or similar
[19:56:39] <CaptHindsight> multitouch is a mess in Linux
[19:56:57] <CaptHindsight> but with tweaking regular touch is OK
[19:57:09] <DRGray> what the driver is in the screen?
[19:57:37] <os1r1s> CaptHindsight Do you just use the KB/Mouse from the monitor or do you have another set up?
[19:58:06] <CaptHindsight> thats from 2 years ago, so looks like Ubuntu, Linuxcnc 2.6 and axis
[19:58:28] <CaptHindsight> since it has USB you can do both
[19:59:02] <CaptHindsight> the guy using that machine had to program all his g-code by hand so he added a keyboard and mouse
[19:59:20] <CaptHindsight> but he could run programs easily just off the screen
[19:59:46] <os1r1s> CaptHindsight That's great. I was actually looking for that. Thanks
[19:59:50] <CaptHindsight> so running programs its ok
[19:59:55] <DRGray> my plan is to build a integrated box. so i can use it to run my devices
[20:00:07] <CaptHindsight> but is you have lots to type add a real keyboard
[20:01:03] <CaptHindsight> DRGray: you can see we used a belt on that gantry
[20:01:15] <os1r1s> CaptHindsight I'd mostly run. I had seen some enclosures with a hole for a 15" touchscreen. But now I can't find that.
[20:01:40] <CaptHindsight> ~1.5m belt drive positioner driven by a stepper with a timing belt
[20:02:16] <CaptHindsight> DRGray: ^^^ going back to your stepper and belt question
[20:03:09] <DRGray> yes, i picked up on that
[20:04:03] <CaptHindsight> http://imagebin.ca/v/2YYdKapfx0Bu better pic
[20:04:49] <DRGray> looks good
[20:05:05] <DRGray> so you have mounted the drivers in the atx case?
[20:05:58] <CaptHindsight> yes
[20:06:24] <CaptHindsight> or on the back of the touchscreen
[20:06:27] <os1r1s> CaptHindsight I'd like to see a closeup of that too
[20:06:39] <CaptHindsight> along with the motherboard
[20:06:56] <CaptHindsight> don't have a pic
[20:08:40] <DRGray> in the first pic whats that device doing droping some sort of liquid?
[20:10:20] <CaptHindsight> it has a single dispensing valve
[20:10:26] <DRGray> inking?
[20:10:41] <CaptHindsight> anything you want that will flow
[20:10:53] <DRGray> small droplets?
[20:11:11] <CaptHindsight> or segments
[20:11:42] <DRGray> splatter?
[20:11:48] <CaptHindsight> the valve open/close is ~100ms
[20:11:49] <DRGray> or accurate?
[20:12:05] <CaptHindsight> accurate as the gantry is
[20:12:20] <CaptHindsight> that one was ~30um
[20:12:54] <DRGray> so droplets of ~30um diameter?
[20:13:05] <CaptHindsight> no the accuracy
[20:13:24] <CaptHindsight> with an injet nozzle you can do 30um drops
[20:14:26] <DRGray> so is that stock bough or have you built the dropper setup?
[20:14:29] <CaptHindsight> http://www.microcenter.com/product/422089/Cooler_Master_HAF_Stacker_915R_Mini-ITX_Mod_Tower_Computer_Case you can fit everything into a case this size as well

[20:14:58] <DRGray> sorry for all the questions but it could be useful for a project im working on
[20:16:49] <CaptHindsight> you can buy dispensing valves

[21:19:46] <gregcnc> The color is in the pore. The aluminum oxide is usually transparent. Corundum is aluminum oxide and varies from transparent to not so much. transparency of anodizing varies with base alloy.
[21:20:03] -!- Duc [Duc!~Duc@24.96.23.106] has joined #linuxcnc
[21:20:55] <pcw_home> I though that the oxide layer was porous (and transparent) so the dye is absorbed in the oxide layer,
[21:20:57] <pcw_home> and the sealant seals the surface to keep the dye from leaching out

[21:41:38] <CaptHindsight> the anodic layer sits on top of the aluminum a few microns thick
[21:42:08] <tiwake> CaptHindsight: but the dye can "fall out" until its sealed
[21:42:23] <CaptHindsight> or wash out
[21:42:26] <tiwake> CaptHindsight: what I don't understand is why we can still see the dye after its sealed
[21:42:35] <CaptHindsight> sealing swells the pores shut
[21:42:40] <XXCoder> tiwake: alum rust is clear
[21:42:51] <CaptHindsight> the thin layer of oxide is transparent
[21:42:54] <XXCoder> you have never touched alum itself, it rusts over instantly
[21:43:30] <tiwake> ok so it is indeed an oxide layer above the actual dye that is so thin that light can pass though it
[21:43:40] <CaptHindsight> as it gets thicker it becomes more translucent to opaque, as in hard anodize
[21:43:41] <XXCoder> and transparent
[21:43:47] <gregcnc> Sapphire is aluminum oxide, if colored,due to impurities. Sapphire windows or phone glass?
[21:43:51] <XXCoder> there is gem class that IS all alum rust
[21:44:02] <XXCoder> ah sapphire, I couldnt recall name
[21:44:10] <gregcnc> corundum
[21:44:26] <CaptHindsight> it depends on how you control the structure
[21:44:40] <XXCoder> CaptHindsight: same as carbon
[21:44:45] <CaptHindsight> transparent aluminum is clear and may be an inch thick
[21:44:48] <gregcnc> right the crystaline structure has an impact
[21:44:52] <XXCoder> there is many forms of carm structure, including one for diamond
[21:45:01] <XXCoder> *carbon
[21:45:35] <gregcnc> so is each pore essentially a single crystal?
[21:45:46] <tiwake> interesting
[21:46:10] <XXCoder> gregcnc: the setup is designed to shape em
[21:46:17] <XXCoder> so it has holes
[21:46:27] <XXCoder> you then fill em then put em in water and pores close
[21:46:28] <XXCoder> done
[21:46:35] <tiwake> the oxide layer is the entire anodized thing, but the oxide its self is structured to be transparent to (at least) visible light
[21:47:03] <tiwake> and the dye is intermingled with the oxide
[21:47:37] <CaptHindsight> it's physically trapped by the oxide
[21:47:54] <CaptHindsight> when it becomes hydrated
[21:48:36] <tiwake> thats what I suspected, but wasent sure
[21:48:44] <tiwake> well, sorta suspected
[21:49:40] <CaptHindsight> http://www.finishing.com/210/63.shtml
[21:51:04] <CaptHindsight> tiwake: so before and during sealing water based dye can rinse out
[21:51:26] <CaptHindsight> solvent based is not effected by the water so it sticks like glue
[21:51:37] <tiwake> right

[22:32:14] <enleth> idea of the day: use an electric kettle full of water as a braking resistor for the VFD

[22:35:49] <CaptHindsight> kettle full of maple syrup
[22:36:00] <Tom_itx> dude i chat with in another channel drinks it all the time..
[22:37:59] <Tom_itx> i like it when it's cold out
[22:39:39] <enleth> OTOH, a sealed water vessel with a safety valve, a floater for water level monitoring (and possibly replenishment, like in a toilet tank) and of course a heater inside would indeed be a very effective and compact braking resistor
[22:39:53] <enleth> I wonder if anyone used something like this commercially in the days of olde
[22:40:44] <enleth> lots of crazy shit, by today's standards, was once state of the art

[22:58:52] <SpeedEvil> copper sulphate resistors are/were popular as insane-o-power dump resistors for HV stuff
[22:59:57] <enleth> FYI a 600W tourist kettle turns out, if my calculations are right, to be a perfect braking resistor for the 2.2kW inverter I have
[23:00:30] <enleth> if it wasn't so expensive to replace a burnt out inverter, I'd actually give it a try

[23:44:22] <_methods> space x launch
[23:44:27] <XXCoder> it is related to how as soon as you need something you havent needed for quite a while are suddenly hard to find.

[23:46:17] <FloppyDisk> Rigidtapping mesa hostmot2 question: If my index pulse is not exactly one spindle revolution, is that an issue?
[23:47:12] <FloppyDisk> In looking at the hostmot2 component, (bit in/out) index-enable --> When this pin is set to True, the count (and therefore also position) are reset to zero on the next Index (Phase-Z) pulse. At the same time, index-enable is reset to zero to indicate that the pulse has occurred.

[23:48:13] <FloppyDisk> My ISSUE - is that I put the encoder on the back of the spindle MOTOR and not on the spindle itself... I can scale the counts, but how do you scale a 1 count per rev z signal??
[23:48:16] <FloppyDisk> If at all....
[23:49:33] <PetefromTn_> Aw man looks like a downrange safety abort
[23:49:57] <PetefromTn_> I can't wait to be back in Florida and be able to watch these from my backyard ;)
[23:50:56] <_methods> yeah
[23:51:05] <_methods> screwed up valve i guess
[23:51:15] <XXCoder> not a surpise, no captions
[23:51:52] <PetefromTn_> no valve problem there is a ship in the downrange safety area
[23:51:54] <_methods> oh something was in range
[23:51:57] <_methods> yeah
[23:53:06] <PetefromTn_> so is it a hold or an abort?
[23:53:28] <_methods> hold
[23:54:02] <PetefromTn_> Oh cool. launch window is like 76 minutes I think they said...
[23:54:11] <XXCoder> makes sense as ship in range is easily fixable
[23:54:17] <XXCoder> just tell it to buzz off
[23:54:43] <PetefromTn_> yeah man bugger off ;)
[23:54:53] <PetefromTn_> ships take a bit to get somewhere tho
