[00:00:24] <pink_vampire> Elmo40: nut much, the c10 it not opto isolated
[00:08:38] <_unreal_> pink_vampire, Thats part of the reason why I want to get the tinker board up and running
[00:08:43] <_unreal_> faster GPIO
[00:09:09] <_unreal_> and a lot more I/O's then par port
[00:09:25] <pink_vampire> i told you the logo is cute

[07:24:55] <XXCoder> wow i can see color of table top!
[07:25:03] <XXCoder> its... greenish?
[07:41:12] <Elmo40> Loetmichel, was that a 'make work' project? ;-)
[07:41:25] <XXCoder> lol
[07:41:32] <XXCoder> doubt he needs more work!
[07:41:46] <Elmo40> everyone needs more work!
[07:41:59] <XXCoder> nicely lined up lol
[07:42:00] <Elmo40> get married. it piles up real quick
[07:42:29] <Elmo40> honey-do lists... weekends are not for resting. that is a myth.
[07:42:44] <Loetmichel> Elmo40: yes
[07:43:06] <Loetmichel> XXCoder: its an ESD mat
[07:43:11] <Loetmichel> grounded

[08:18:35] <Elmo40> XXCoder, well, what more do you need?
[08:19:08] <Elmo40> 3D printing is the most overkill game I know of. People using 4080 aluminum extrusion... for nothing!
[08:19:32] <Elmo40> their prints are any better or made any faster than a $150 plastic i3 clone.
[08:20:42] * Loetmichel is just reading the nutrition label on those biscuits... ouch, that will go driectly to my hips: http://www.cyrom.org
[08:21:02] <Elmo40> LoL
[08:25:03] <Elmo40> XXCoder, or were you laughing at the non-genuine windows pop-up? :-P
[08:32:48] <rmaw> I just bought a $200 ender 3 and its fine, when your squidging liquid plastic together the tolerance on your can be pretty loose
[08:33:58] <rmaw> that wood one would prob be pretty solid its so small

[09:09:40] <Elmo40> true. it would be fairly rigid. the pen sliders, though... they wont be.
[09:09:45] <Elmo40> but it doesnt move much.
[09:09:52] <Elmo40> and plastic is NOT accurate.
[09:13:01] <gregcnc> who works in one of these? https://bn.craigslist.org
[09:16:03] <miss0r2> etf lol
[09:16:07] <miss0r2> wtf*
[09:16:46] <Loetmichel> Elmo40:the pen sliders are just superficial
[09:16:52] <Loetmichel> at least in the y axis
[09:17:08] <Loetmichel> the two spindles with brass nuts are way more rigid than the sliders
[09:18:39] <Elmo40> true
[09:18:49] <Elmo40> i like the dvd laser drive
[09:18:53] <Elmo40> that is functional
[09:23:43] * Loetmichel used steppers from 5.25" floppy drives back in his first CNC
[09:24:08] <Loetmichel> -> http://www.cyrom.org
[09:24:21] <Loetmichel> acrylics for chassis wasnt my brightest moment though ;)
[09:25:51] <miss0r2> I think its cute :) Still a few factors better than the generic chinesium :)
[09:26:15] <Loetmichel> back then there WAS no chinesium
[09:26:25] <Loetmichel> that was in 1995 IIRC
[09:26:40] <miss0r2> sure there was.. but it was all bamboo, and they didn't export it yet :)
[09:27:16] <Loetmichel> here in europe i meant

[10:22:07] <SpeedEvil> Make those sidepieces a box beam and the back of the motor support one too, even out of 1/2" ply, and make it a lot more rigid in two axes and rotation
[10:22:39] <SpeedEvil> But it may be fine for its intended app.

[10:42:42] <fdarling> has anyone used at_pid (auto-tuning PID)? I have some questions about P/I/D vs P/I/FF1 and the scaling of output to user units per second
[10:43:16] -!- P1ersson has quit [Ping timeout: 264 seconds]
[10:43:24] -!- Inline has joined #linuxcnc
[10:46:31] <pcw_home> For velocity mode servos FF1 is easy to calculate so no need to guess
[10:47:14] <fdarling> pcw_home: what about for current mode servos?
[10:47:29] <pcw_home> 0 FF1 for torque mode
[10:47:50] <pcw_home> FF2 dependent on inertial load
[10:48:39] <pcw_home> velocity mode typically needs no D, torque mode does
[10:49:32] <pcw_home> torque mode also typically needs higher servo thread rates (since you need to close the velocity loop in LinuxCNC)
[10:50:05] -!- Sabotender has joined #linuxcnc
[10:50:46] <fdarling> pcw_home: I have several machines, most of them have brushed DC servos that operate in torque mode I believe (the amplifiers definitely don't handle any feedback...) but one of my machines has Yaskawa servos/drives and I think it takes an analog *velocity* signal not torque signal
[10:51:01] <fdarling> pcw_home: the Yaskawa one is what I'm currently worried about tuning
[10:52:26] <fdarling> pcw_home: there are several pages online about tuning PID for servos in LinuxCNC, which one do you recommend?
[10:52:34] <Loetmichel> SpeedEvil: you mean like this? -> http://www.cyrom.org
[10:52:35] <pcw_home> It would be odd to have a machine of the vintage that used brushed motors without tachometer feedback
[10:52:57] <Loetmichel> http://www.cyrom.org
[10:52:58] <Loetmichel> :-)
[10:53:01] <fdarling> pcw_home: well... call my stuff odd then ;-)
[10:53:14] <pcw_home> what are the drives?
[10:53:17] <SpeedEvil> Loetmichel: yes.
[10:53:48] <Loetmichel> SpeedEvil: already corrected in the "new" construction... the first pic was my fist BIG machine
[10:53:48] <SpeedEvil> Loetmichel: if the above is the same item, :)
[10:53:53] <fdarling> pcw_home: guess what, I bought cncwiki.org :-) https://www.cncwiki.org
[10:53:54] <SpeedEvil> ah
[10:53:57] <SpeedEvil> fair enough
[10:53:59] <Loetmichel> no, its a second machine
[10:54:53] <fdarling> pcw_home: one of my machines has custom potted locked antiphase drivers on the back of the brushed DC motors, so it's taking a 20kHz PWM signal that must have a duty cycle that isn't 0% or 100% and directly driving the H-bridge off that
[10:55:20] <Loetmichel> i did a lot of "testing" on the first one... including using bicycle chains for the stepper-> ballscrew coupling
[10:55:26] <Loetmichel> worked "so lala"
[10:55:42] <pcw_home> so the elmo drives are either torque or velocity mode
[10:56:08] <Loetmichel> http://www.cyrom.org
[10:56:17] <fdarling> pcw_home: yes, but in my case the Baldor servos they are attached to do not have tachometers, only encoders. The Elmo drive doesn't deal with encoders and the drives are configured for current mode
[10:56:19] <Loetmichel> was loud and not really precise
[10:56:32] <Loetmichel> in the end i got back to using timing belts
[10:56:45] <pcw_home> a PWM drive (voltage mode) is tuned somewhere between torque and velocity mode
[10:56:52] <Loetmichel> and also timingbelts for the sync in the back of Y
[10:57:08] <fdarling> pcw_home: I am working on populating that wiki with information about servos, servo drives, servo power supplies, and of course Mesa cards and LinuxCNC itself
[10:57:41] <Loetmichel> it was a "königswelle" beforehand: http://www.cyrom.org
[10:57:51] <pcw_home> for torque mode the more D you can get the tighter the tuning (and you can get higher D at higher loop rates)
[10:58:45] <Loetmichel> now its two timing belts (couldnt get a long enough one) and a central tensioner: http://www.cyrom.org
[10:59:04] <pcw_home> so for torque mode I set a small stable P value than run D up as high as possible (until it get too crunchy/buzzy)
[10:59:05] <Loetmichel> http://www.cyrom.org
[10:59:09] <Loetmichel> worked WAY better
[10:59:56] <fdarling> pcw_home: what servo thread rate would you recommend? I am using an Ethernet based card by the way
[11:00:39] <pcw_home> that makes it a bit harder, as you probably want at least 2 KHz for torque mode drives
[11:01:25] <pcw_home> some hosts are ok at 4 KHz with Ethernet but typical low power hosts are not
[11:01:34] <fdarling> pcw_home: the 7i77 isn't isolated from the FPGA card right? only the field I/O?
[11:01:44] -!- Sabotender has quit [Ping timeout: 272 seconds]
[11:02:21] <pcw_home> no the encoder/analog is not isolated (If I did it again I would isolate the analog section)
[11:02:42] <pcw_home> we do have a isolator for the 7I77
[11:03:01] <fdarling> pcw_home: I saw that, there was something about having to compensate for skew or something
[11:03:20] <pcw_home> if the PC is in the control cabinet its usually not an issue with the PCI/PCIE cards
[11:04:06] <fdarling> pcw_home: the PC is currently a Dell Optiplex 755 sitting on a desk near it, I'm worried about having a machine with 208VAC 3-phase that uses ground as a neutral being hooked to it :-S
[11:04:15] -!- Sabotender has joined #linuxcnc
[11:04:17] <pcw_home> but occasionally if the PC in remote you get ground loops (especially with drives that dont have differential inputs)
[11:04:25] <pcw_home> PC is remote
[11:04:36] <fdarling> pcw_home: although that machine is the velocity one, it's the others that use torque mode
[11:05:16] <pcw_home> yeah torque mode tuning is very different, like I said its all in how much D term you can use
[11:05:40] <fdarling> pcw_home: how does one calculate FF1 for velocity mode?
[11:05:53] <pcw_home> (or how much P term you can use in a velocity loop if you use nested PID loops in LinuxCNC)
[11:06:35] <pcw_home> I think the easiest way is to measure or calculate the machine velocity at 10V
[11:07:11] <fdarling> pcw_home: in my case the notes for the original controller do tell me what speed the 10V signal results in, it was calibrated by the machine tool builder
[11:07:16] <pcw_home> use that number as the output scale (so the PID output is scaled in machine units per second)
[11:07:26] <pcw_home> then FF1==1.0
[11:07:31] <fdarling> *notes do, missed a word there
[11:08:03] <fdarling> pcw_home: I was really confused by the PID output limit and scale vs the 7i77's output scale and min/max
[11:09:46] <pcw_home> if you get say 5 IPS as the velocity at 10V the min_limit = -5 max_limit = 5 maxscale = 5
[11:11:03] <fdarling> pcw_home: the terminology confuses me, what does it mean by "limit" in this context? At first I thought it meant the voltage output bounds, like -5 to +5V in that case
[11:11:53] <pcw_home> they are bounds of the input range (but they are affected by scale)
[11:12:51] <pcw_home> they are not output bounds (which would be in volts)
[11:13:22] <fdarling> pcw_home: so the larger the number, the smaller the output voltage for the same input?
[11:13:30] <pcw_home> Yes
[11:14:11] <pcw_home> same as most of LinuxCNCs scaling (scale everything to machine units)
[11:14:14] <fdarling> pcw_home: this has probably been an issue for my setup, it sounds like I need to first correctly set the 7i77's analog scaling values...
[11:14:22] -!- P1ersson has joined #linuxcnc
[11:15:23] <fdarling> pcw_home: this machine goes 400 IPM so 6.66 IPS by the way, it was the max the original controller supported. I'm not sure what the actual limits of the mechanical components are...
[11:17:05] <pcw_home> The actual velocity at 10V will be higher (since you need headroom for the control loop to run at 400 IPM)
[11:17:55] <fdarling> pcw_home: I'll have to consult the notes from the machine tool builders, they say what the 10V speed is. I could measure it, but I think it might be dangerous... this machine is scary at full speed :-S
[11:18:39] <fdarling> pcw_home: I could probably measure it by disconnecting the timing belt from the servo to the ballscrew and going off how far it "thinks" it's traveling, right?

[11:24:31] <pcw_home> You can also measure it by setting FF1=1 and tuning the output scaling...
[11:25:29] <pcw_home> and yes its safer for initial tuning to disconnect the linear motion components...
[11:30:04] <fdarling> pcw_home: so to begin tuning velocity mode, you said I should have FF1=1 after getting the scaling correct. What about P/I/D? Should P have some initial value?

[14:35:40] <Jymmm> For those of you in EU, when you buy a "bucket (not can) of paint", how much are you getting in a bucket?
[14:36:54] <fdarling> pcw_home: do I really need feedback for commutation though? If I run slowly enough, the motor should just follow along like a compass right? (in the case of a permanent magnet motor obviously)
[14:37:43] <fdarling> pcw_home: for an inductive motor, the higher the frequency the more torque and speed minus slippage, right? Basically I am saying to run it like a VFD, but I am not sure how I would do that with LinuxCNC or HAL...
[14:38:13] -!- net| has joined #linuxcnc
[14:38:38] <fdarling> pcw_home: accidental torque reversal is fine for my testing purposes at this point
[14:44:46] <pcw_mesa> you can run it like a step motor but is tends to be unstable (some of the commutation alignment schemes run the motor in this mode before commutation is established)
[14:45:23] <fdarling> pcw_mesa: what do you mean by unstable?
[14:47:04] <fdarling> pcw_mesa: at any given instant under steady state it would be okay, right? it's just under motion it might be rough?
[14:47:18] <pcw_mesa> it suffers from the same resonance issues a step drive does
[14:48:05] <fdarling> pcw_mesa: yes I agree with you there, obviously under load to regulate speed you need feedback with an inductive motor, and with a permanent magnet motor you absolutely need feedback if you're trying to prevent torque reversal from lagging too far behind, and there is the issue of resonance like you're saying where you can actually end up too far ahead (and then behind)

[14:48:12] <pcw_mesa> so for example as a spindle with an interrupted load it might
[14:48:14] <pcw_mesa> lose sync
[14:48:49] <fdarling> pcw_mesa: again I would be doing this just for testing if a motor is dead or not, not for anything long term
[14:49:01] <pcw_mesa> yeah OK for that
[14:49:12] <fdarling> pcw_mesa: how do I set it up in LinuxCNC though?
[14:50:35] <pcw_mesa> set a fixed 8I20 current, and use a incrementing count for the 8i20 angle

[16:14:26] <pink_vampire> Hi everyone
[16:17:46] <Rab> How come the paint is sold in kg instead of liters?
[16:19:03] <pink_vampire> smaller volume, and you think you are getting more
[16:19:48] <Rab> It seems like the weight would vary depending on composition, though.
[16:21:17] <pink_vampire> correct
[16:22:10] <ve7it> could be easier to meter the fill process by weight... no flow meter to clean
[16:22:14] <pink_vampire> but very easy to measure in large quantity
[16:22:32] <pink_vampire> i have load cell here..
[16:23:00] <pink_vampire> it was damaged and i was able to fixed it

[16:34:08] <asdfasd1> anyone experienced in electroplating?
[16:35:11] <pink_vampire> yes
[16:35:19] <pink_vampire> i did anodizing
[16:35:43] <pink_vampire> asdfasd1: ^
[16:35:51] <asdfasd1> anodising is not plating :)
[16:36:22] <asdfasd1> the problem I have seems to be only on plating
[16:36:45] <pink_vampire> but it is similar in some way
[16:37:01] <pink_vampire> what is the problem?
[16:37:33] <asdfasd1> the problem is when plating on sharp object, the sharp tip burn very easy
[16:38:09] <asdfasd1> I did try reducing the current but still need improvements
[16:38:24] <pink_vampire> maybe you need to lower the current?
[16:38:53] <asdfasd1> I did lower it to the level where just begin the process very slowly
[16:39:04] <pink_vampire> if you are using acid maybe it is very strong
[16:39:28] <asdfasd1> but still the tip is more fragile
[16:39:34] <asdfasd1> it is alkaline
[16:39:44] <asdfasd1> nearly neutral
[16:39:46] <pink_vampire> same idea
[16:39:55] <rmu> asdfasd1: shield the tip
[16:40:00] <asdfasd1> PH 8
[16:41:01] <asdfasd1> you mean with isolator?
[16:41:29] <rmu> no with some other metal
[16:41:38] <pink_vampire> https://asterionstc.com
[16:41:49] <rmu> not completely, just enough to slow process down around the tip
[16:42:23] <rmu> shield at same potential as the thing you are plating
[16:42:49] <asdfasd1> I did try temoving some of the anode near the tip
[16:42:53] <asdfasd1> is it the same?
[16:42:58] <asdfasd1> removing*
[16:42:59] <pink_vampire> Better solution agitation, especially near the plated work. Higher temperature. Higher nickel ion concentration.
[16:43:16] <pink_vampire> try to add air stone
[16:43:34] -!- R2E4 has quit [Quit: Going offline, see ya! (www.adiirc.com)]
[16:43:43] <asdfasd1> agitation seems to drive other problems, with high temperature couldnt notice any difference
[16:44:06] <asdfasd1> air is not recommended for iron plating, it introduce oxigen in the bath
[16:44:13] <asdfasd1> only mechanical agitation
[16:44:52] <pink_vampire> or a power head that will move the solution
[16:45:27] <pink_vampire> something that will make it move
[16:45:48] <asdfasd1> it is done in small beaker, with magnetic stirr bar
[16:46:18] <asdfasd1> but somehow when the solution is moving it disturb the plating process
[16:46:34] <asdfasd1> iron plating seems to be very difficult process
[16:46:50] <pink_vampire> in a beaker?
[16:47:14] <asdfasd1> https://5.imimg.com
[16:47:26] <asdfasd1> small scale
[16:47:41] <asdfasd1> on hot plate with magnetic stirring
[16:47:45] <pink_vampire> i know what is a beaker, but to plate like that...
[16:48:08] <asdfasd1> it is small workpiece anyway
[16:48:20] <asdfasd1> 7mm diameter 45mm long
[16:48:42] <pink_vampire> stir can suck air
[16:49:01] <asdfasd1> slow stirr no problem, but somehow it disturb the plating
[16:49:30] <asdfasd1> rmu: have you done such shielding?
[16:59:14] -!- FinboySlick has quit [Quit: Leaving.]
[17:01:01] <rmu> asdfasd1: not really
[17:01:48] <rmu> but electric field near the tip will be very large, ergo there will be higher current, more action
[17:02:38] <asdfasd1> I just realised what you actually told me
[17:02:45] -!- JimPanski has joined #linuxcnc
[17:02:46] <asdfasd1> sound promising
[17:03:04] <asdfasd1> do you think it is better than removing anode around the tip?
[17:03:35] <asdfasd1> or shielding with non conductive piece?
[17:04:11] <rmu> can't say. my experience with actual electroplating is limited. the shield should be conductive and have same potential as the piece you are plating IMO
[17:04:43] <asdfasd1> so Im plating the shield too? isnt it?
[17:04:49] <rmu> yes
[17:05:22] <asdfasd1> thanks, Im going to try it
