[01:55:33] <XXCoder1> hey pcw
[01:56:47] <pcw_home> Hi XXCoder1
[01:58:02] <accuartisans> hey pcw, I don't know if you remember, I got a Gigabyte board like you have and I finially got it up and running under linux kernel 3.14.4 and Xenomai 2.6.3
[01:58:55] -!- sumpfralle1 has quit [Ping timeout: 260 seconds]
[01:59:11] <pcw_home> Thats neat, I have been pretty impressed with the J1800 (for ~10W)
[01:59:27] <accuartisans> I have really good latency results as well. Question what branch are you using to run again your mesa ethernet board?
[02:00:09] <pcw_home> ubc-7i80
[02:00:45] <accuartisans> I did not get the same results you had with rt_preemt, but now that i ahve my bios settings I think I may go back and re-try rt_preemt
[02:01:10] <accuartisans> does that branch support Xenomai?
[02:01:35] <accuartisans> Yes, I amvery impressed with this board
[02:01:35] -!- asdfasd has quit [Ping timeout: 255 seconds]
[02:01:52] <pcw_home> Preemt RT-latency is much worse but for hardware stepgens or servos its not terribly important
[02:02:35] <accuartisans> I have Servo Thread(1.0ms) 3630 and Base thread(25.0us) 8125
[02:02:47] <accuartisans> currently:)
[02:03:07] <accuartisans> i had an issue with SMI but that is resolved now
[02:03:29] <pcw_home> I got about 8 usec/8 usec on RTAI without any fussing
[02:03:52] <XXCoder1> damn
[02:03:56] <accuartisans> is usec smaller than ms?
[02:03:56] <XXCoder1> took me while to find

[02:04:56] <accuartisans> dang then I don't know what I did wrong
[02:05:53] <accuartisans> xxcoder1: thanks!
[02:05:59] <pcw_home> Thats RTAI (I think Preemt-RT was maybe 50 usec or so)
[02:06:25] <accuartisans> care to share your image and header.debs?
[02:07:09] <pcw_home> I can get them tommorow (or try to guess the IP address of the test machine...)
[02:08:09] <accuartisans> just looking at RTAI now, what kernel version did you use?
[02:08:33] <pcw_home> I just built the preemt-rt kernel from source (3.12 and 3.14)
[02:09:04] <pcw_home> The RTAI kernel on the live CD works
[02:09:26] <pcw_home> (2.6.32?)
[02:09:49] <pcw_home> No graphics accel of course
[02:10:35] <accuartisans> I think maybe I should send you my bios settings then, cause I bet I have some a miss
[02:10:44] <pcw_home> The 3.4.55 RTAI kernel bolluxes up the video
[02:11:13] <pcw_home> (hoping a 3.12 RTA kernel is not too long in coming)
[02:11:21] <pcw_home> RTAI
[02:11:36] <accuartisans> that's what I was thinking as I found that 3.14 kernel supports the video way better
[02:12:12] <XXCoder1> when will there be new linuxcnc package?
[02:12:15] <accuartisans> also recognizes the processor a little different if my memory recalls
[02:13:05] <pcw_home> Yeah NP watching FS video with linuxcnc running on Ethernet (I think 3.14.5 preemt RT)
[02:13:07] <Valen> pcw_home: any suggestions for how to take internal pcie slots to external?
[02:13:31] <Valen> the latency over ethernet isn't an issue with that? or is that running steppers?
[02:13:50] <pcw_home> for cabled PCIE: 6I71
[02:13:54] <accuartisans> so, i'm looking at www.atai.org... RTAI 4.0 is available but not sure it supports anything latter than 3.8.13
[02:14:14] <pcw_home> NP with steppers over Ethernet
[02:14:28] <pcw_home> or servos

[02:15:21] <pcw_home> only limitation is that theres a fair amout of latency with Preemt RT so that limus the servo thread to about 2 KHz max
[02:15:29] <pcw_home> limits
[02:16:31] <pcw_home> Under Xenomai/RT-Net I suspect 4 KHz or so is possible but you need a RT-net compatible MAC
[02:17:19] <Valen> whats the utility of doing it though?
[02:17:19] <accuartisans> i believe this board is compatible?
[02:17:35] <Valen> of using it over ethernet for RT stuff
[02:17:55] <pcw_home> For velocity mode drives (and hardware stepgens which are effectivel velocity mode drives) 1 KHz is usually fine
[02:18:01] -!- Thetawaves has quit [Quit: This computer has gone to sleep]
[02:20:19] <pcw_home> Valen ?
[02:21:03] <Valen> i mean, why does one want to run RT over ethernet?
[02:21:10] <Valen> realtime stuff over ethernet
[02:21:18] <Valen> just put a computer out there ;->
[02:23:27] <pcw_home> Yeah but thats another computer (and if you have a lot of RT stuff in HAL its got to be a fast computer also)
[02:24:28] <Valen> computers are cheap ;->
[02:27:21] <pcw_home> The other reson for using Ethernet is that its nearly universal and capable of RT
[02:27:51] <pcw_home> and electrically isolated
[02:28:06] <XXCoder1> I plan to use cat5 for limit buttons too
[02:28:29] <Valen> I can see the use for running ethernet, just running realtime over it seems less usefull
[02:28:52] <Valen> i mean if you ran the firmware where your nice fpga's did all the work sure
[02:29:51] <pcw_home> Why less useful? Its a efficient RT connection to external devices
[02:30:29] <pcw_home> beats USB
[02:30:49] <pcw_home> and its almost always available
[02:33:56] <XXCoder1> pcw know anything about Smithy Granite 1340 ?
[02:34:04] <XXCoder1> my uncle has one and wonder if he could make it a cnc
[02:34:24] <pcw_home> Not much other than I have heard of them
[02:35:14] <XXCoder1> its a mill/lathe thing
[02:35:22] <XXCoder1> made me wonder if linuxcnc could do it
[02:36:15] <Valen> linuxcnc can do anything you want it to
[02:36:29] <Valen> its a question of if you can get the machine good enough to be worth it
[02:36:31] <XXCoder1> including build me a cnc so it can run on it? ;)
[02:36:54] <Valen> on a manual lathe/mill the operator can do a lot of fudging to make up for any inadquacies in the machine
[02:37:06] <Valen> when its CnC most of that goes away
[02:42:07] <Valen> so the machine needs to be as good as you can get it
[02:42:22] <XXCoder1> ok
[02:48:14] <jp_mill> XXCoder1: you might want to check out the smithy site the use LCNC for thier machines if i do remember correctly. There is even a config for them in the live CD. not sure if they cnced the granite
[02:48:31] <XXCoder1> yeah saw the kit
[02:48:35] <XXCoder1> riciously expensive

[03:06:22] <accuartisans> capthindsight: newer RTAI? what kernel/patch will that be for I wonder?
[03:09:14] <CaptHindsight> accuartisans: the new development does on at the shabbyx git, then it goes to rtai.org, then that gets tested and starts back over at shabbyx
[03:12:46] <accuartisans> thanks, i was wondering why I saw no repository on rtai.org. So, do you know if a patch is being worked on for linux 3.14?
[03:13:57] <CaptHindsight> the scheduler needs to be fixed to get passed 3.4

[03:22:37] <vit-14> but i dont see it on ebay

[03:28:20] <CaptHindsight> vit-14: basically they have the torch on a slide with a spring
[03:28:53] <CaptHindsight> there is a switch contact that stay open when the probe is at the bottom of its travel

[03:43:31] <CaptHindsight> this is closer to what you want

[03:44:52] <CaptHindsight> you just need those rings on the probes to be far enough away from the torch tip to not be harmed
[03:45:45] <CaptHindsight> vit-14: the probe just tells you where the surface of the material is, you have to decide when you want to cut
[03:46:03] <CaptHindsight> where and when and what shape
[03:46:21] <CaptHindsight> vit-14: do you have a cnc machine with a torch on it?
[03:46:37] <zeeshan> CaptHindsight:
[03:46:39] <vit-14> im building but omg very difficult
[03:46:43] <zeeshan> can you get those digitizing probes (3d)
[03:46:44] <zeeshan> for cheap?
[03:46:52] <zeeshan> 200$ is the street price that i see ;p
[03:48:01] <Valen> digitizing probe?
[03:48:51] <mozmck> afaik the only really reliable way to sense torch height is to measure the voltage across the gap when cutting.
[03:49:00] <vit-14> no i sure how it work or calibrate the machine when going cutting
[03:49:59] <CaptHindsight> Valen: have you ever seen an stepper controller with an easy to use GUI for non-programmers? Example applications might be small lab gantries, simple pick-n-place etc
[03:50:08] <vit-14> but how in this video is automatic
[03:50:16] <vit-14> https://www.youtube.com/watch?v=HZlV4dUuvMI
[03:50:26] <Valen> nothing springs to mind
[03:50:42] <CaptHindsight> I can't find one either
[03:51:54] <vit-14> but i need to have one? or i can cutting without him?
[03:52:12] <zeeshan> valen its a probe you can throw in a spindle
[03:52:20] <zeeshan> and use to measure coordinates for a part

[03:52:22] <zeeshan> and reverse engineer ;p
[03:53:01] <CaptHindsight> vit-14: if your material is flat then you can just jog the Z axis torch into position and start cutting at the Z position
[03:53:42] <mozmck> vit-14: for initial height sensing you can use a floating head with a mechanical switch. This is probably the most common.
[03:53:49] <CaptHindsight> vit-14: they just wanted to automate that on their cutter
[03:54:40] <mozmck> Ohmic sensor is common and works well, I haven't used the capacitive, but that large ring could get in the way depending on what you are cutting.
[03:54:44] <CaptHindsight> they lower the Z until the switch closes then they know the height of the surface
[03:55:29] <CaptHindsight> yeah the rings aren't ideal
[03:55:44] <mozmck> yes, if you are cutting much of anything you really need the initial height sensing.

[03:56:01] <CaptHindsight> but lower cost than a laser micrometer
[03:56:54] <mozmck> :) higher than a floating head setup though.
[03:57:32] <CaptHindsight> vit-14: is trying to buy something he can just bolt on
[03:57:32] <mozmck> You will find also that if you are cutting anything thin at all a full THC is essential.
[03:57:50] <vit-14> the material is flat
[03:58:12] <mozmck> If it is thin, it won't be flat once you have cut a little bit.
[03:58:27] <mozmck> the heat causes the metal to warp...
[03:58:35] <XXCoder1> unless vacuum held?

[04:09:17] <Aero-Tec> is there a quick and simple program or any info on doing that?
[04:09:49] <Aero-Tec> whack for me, might not be for you guys
[04:10:17] <Valen> gcode in theory shouldn't need conversion
[04:10:18] <Valen> lol
[04:10:35] -!- vit-14 has quit [Quit: Saliendo]
[04:10:36] <Aero-Tec> some where around 50 or so programs, most hand coded
[04:10:43] <Aero-Tec> lol
[04:10:52] <Valen> what do you need to change?
[04:10:59] <Aero-Tec> true, in theory
[04:11:30] <Aero-Tec> I need to get it working on a LinuxCNC unit
[04:11:32] <CaptHindsight> it gets harder when you have 47 custom M codes
[04:11:44] <Valen> what i mean is what changes do you need to make
[04:11:48] <Aero-Tec> so every thing needed to get it running on linuxcnc
[04:12:40] <Valen> gcode isn't "mach" or "linux cnc" it really should "just work"
[04:12:47] <CaptHindsight> Aero-Tec: what happens when you load the programs into the Linuxcnc sim?
[04:13:03] <CaptHindsight> do you get errors?
[04:13:13] <Aero-Tec> it will not load, and linuxcnc has different Gcodes they use and interpret them differently
[04:13:18] <Aero-Tec> like threading
[04:13:34] <Aero-Tec> yes, lots of errors
[04:13:44] <Aero-Tec> then the code will not work right
[04:14:33] <Aero-Tec> I have gone through and fixed errors only to have it do some weird stuff
[04:15:20] <Aero-Tec> was just hoping I could use a converter program and it would work
[04:15:34] <Aero-Tec> wishful thinking
[04:16:51] <Aero-Tec> seeing as I write code and know some things about what is different I might have to write one myself
[04:17:23] <Valen> I'm presuming that sed would do pretty much everything
[04:17:24] <Aero-Tec> thing is it is all old mach code
[04:17:41] <Aero-Tec> not sure if the new version uses the same code
[04:18:23] <Aero-Tec> they are making a new mach program
[04:19:41] <Aero-Tec> I was really hoping not to have to write one, and do all the research into what is different and why
[04:21:00] <Valen> have a look at the errors, most of them are probably going to be setup
[04:21:22] <Aero-Tec> I wish
[04:21:31] <Aero-Tec> way more then that
[04:21:55] <Valen> I would guess that the ones further on follow on from the setup

[04:22:31] <Aero-Tec> I have lathe code and mill code
[04:22:49] <KimK> MrHindsight: Thanks for the info. I must have a different version of E350 than the one you guys were discussing, as mine do have a parallel port, and one standard PCI port. I'm not sure if it also has a PCIe port, let me check. No, just one standard PCI:

[04:22:50] <Aero-Tec> threading is a whole different thing
[04:23:13] <NickParker|2> Hey everybody, I have a 2HP DC spindle, and a spindle controller that's looking less and less likely to ever work. Can anybody point me to a controller linuxcnc can control?
[04:23:40] <NickParker|2> I've only found ones with manual inputs so far (knobs and switches)
[04:23:57] <Aero-Tec> thought linuxcnc can control them all
[04:24:12] <KimK> Hi NickParker|2 , what's the voltage and current of your motor?
[04:24:21] <Aero-Tec> no remote input port?
[04:25:00] <NickParker|2> 12 A currrent, 1500W power, so we can infer ~125V
[04:25:01] <KimK> NickParker|2: I presume you mean your spindle controller is beyond repair?
[04:25:32] <Aero-Tec> they would normally have a port and a way to stop using the local pot and have a 1 to 10 volt, or 1 to 5 volt input
[04:25:38] <NickParker|2> KimK: Well we'll see. It *might* be as simple as a dead SCR. But the whole mill is turning 35 this year.
[04:26:47] <Aero-Tec> thanks for the help

[04:27:43] <NickParker|2> http://www.coleparmer.com/Product/Basic_Variable_Speed_DC_Motor_Controller_for_1_4_to_2_hp_motors/EW-70100-10 This looks like it would work if it had remote input port
[04:28:59] <KimK> NickParker|2: If your controller only has a local pot input, look and see if the controller provides the pot a built in source of +5 or +10 or so across the pot. If so, you might be able to use one of many analog input isolators available (or make your own). Don't skip this step, as many (most) small DC controllers use a hot-chassis design, and don't take well to external 0-10V DC without isolation.
[04:29:54] <KimK> Looking now...

[04:36:39] -!- PetefromTn_ has quit [Quit: There's nothing dirtier then a giant ball of oil]
[04:38:01] <KimK> OK, page 23 of the manual (
http://www.coleparmer.com/Assets/manual_pdfs/70100-10.pdf ) says that you can connect an isolated voltage source as from the Minarik PCM4 (or similar) of 0-1.4 (125V) or 0-2.8V (250V) so unusual voltages, but scalable to 0-5 or 0-10 or something.
[04:38:54] <NickParker|2> I'm already using an op amp as a low pass filter to make my 0-10, changing the gain for their voltage range is trivial.
[04:38:57] <KimK> BTW since this is a Minarik drive, you can almost certainly find a cheaper dealer than Cole-Parmer. (I'm just sayin')
[04:39:09] <NickParker|2> please, point me to a cheaper option.
[04:39:16] <NickParker|2> They were just the first google result.
[04:40:31] <KimK> Well, I haven't looked, I just know Cole-Parmer is high. Although probably very convenient one-stop shopping for those with unlimited budgets.
[04:42:17] <KimK> You might want to keep your op-amp and your 0-10, and then run through the isolator at a 0-10 scale, then come out of the isolator at 0-10, and only then scale down with resistors at the drive.

[04:44:02] <NickParker|2> could also just pwm through an opto then do the op amp on the isolated side.
[04:44:04] <NickParker|2> no?
[04:44:25] <KimK> Your "bad" drive is likely also capable of accepting an isolator, so check into that too, maybe save yourself some money.
[04:45:25] <NickParker|2> KimK: it's not isolation we're struggling with. Restored to original LinuxCNC free condition the spindle controller doesn't respond to inputs.
[04:45:46] <NickParker|2> But I have more theories about why that is that I'll try tomorrow.
[04:48:20] <KimK> OK, I don't mean to interrupt your troubleshooting. If you can find a bad SCR or whatever, and get it going in local pot mode, great! The isolator part comes after that, where you want to control with an external (to the drive) 0-10V.
[04:54:00] <NickParker|2> Yeah thanks for all your help. Hope I get the dinosaur working tomorrow, and iff not I'lll probably buy myself a nice minarik drive.

[15:21:25] <malcom2073> So i have HAL pwmgen enabled and set to a value of 42, but a LED I have attached to that output is pulsing as if the pwm was cyling from 0 to 100%, then back to 0, and repeating. Am I misunderstanding how the pwm stuff works?
[15:25:23] <jdh> it puts out 5v always. teh PWM is how long it is on per cycle
[15:26:58] <malcom2073> Right, and a LED attached to a pwm channel will vary in brightness based on how long 5v is applied during that cycle, so a solid PWM value should mean a solid LED brightness
[15:27:14] <SpeedEvil> what is the PWM rate.
[15:27:28] <SpeedEvil> The pwm rate needs to be >>10Hz to not flicker
[15:27:47] <SpeedEvil> Ideally ~1000Hz

[17:56:05] <malcom2073> IchGuckLive: I have some solid state relays, I didn't read teh spec sheet, over 5amps they need heatsinking. I was running 10amps through it and it got QUITE hot :)
[17:56:56] <IchGuckLive> nice shop heater !
[17:57:12] <malcom2073> It got up over 100C (tested by dripping water on the surface)
[17:57:26] <malcom2073> So... may be ruined? I'll try it out once I get a heatsink and see haha, but I'm buying a spare
[17:58:07] <Jymmm> malcom2073: Opto22?
[17:58:17] <Jymmm> well, nm
[17:58:18] <malcom2073> Jymmm: SSR-60-DD
[17:58:40] <Jymmm> Opto has a warranty, but they are super nazi about it.

[17:59:39] <malcom2073> Jymmm: Yep, have a few of that type on order
[17:59:44] <Jymmm> lol
[17:59:56] <malcom2073> I put a CPU heatsink on my second one, kept it quite cool to the touch
[18:01:46] <pcw_home> Probably done with a OPTO/Darlington so high voltage drop (1.5 or 2V), hence the need for a heatsink
[18:02:23] -!- zzolo has quit [Quit: zzolo]
[18:03:55] <malcom2073> pcw_home: from what I've read (no datasheet available on the $10 unit), most of these have a 1-1.5v drop, so anything over 5amps needs heatisnking
[18:05:04] <malcom2073> So it'll get me up and running, but tbh losing that much power may make me consider getting a higher efficiency solution, that's a lot of heat
[18:06:31] <pcw_home> Dont know if there are better MOSFET based modules available
[18:06:52] <skunkworks__> wow - dell server seems to have eaten 4 memory sticks
[18:07:36] <pcw_home> Thats an expensive habit
[18:08:14] <skunkworks__> assuming that it is the memory and not some odd memory control/motherboard issue.. I have none to swap out.
[18:08:43] <skunkworks__> yes - 4gb sticks of ecc pc3
[18:08:52] <pcw_home> Yow
[18:09:07] <CaptHindsight> "Dude, you got a Dell"
[18:09:09] <Jymmm> skunkworks__: Can you test individually, or does it need pairs?
[18:09:28] <pcw_home> Probably need another rsystem to verify that the memory is truly dead

[18:10:31] <skunkworks__> It will boot with just one.. out of the 6 sticks - only 2 work
[18:11:02] <skunkworks__> it disables the lanes at bootup (bad sticks)
[18:11:03] <Jymmm> skunkworks__: Try swapping to other slots, could be a bad socket too, I've seen that before.
[18:11:11] <pcw_home> just suddenly happened on a working system?
[18:11:15] <skunkworks__> yes
[18:11:23] <skunkworks__> we did have some lighting this last weekend...
[18:11:36] -!- ries_ [ries_!~ries@190.9.171.121] has joined #linuxcnc
[18:12:02] <IchGuckLive> skunkworks_ lightning did cost about 1Mio here in the last 2 days
[18:12:48] <skunkworks__> I think in the dells - you need to start with slot 1a,1b and so on..
[18:13:00] <IchGuckLive> USAFB took 2 full hits and the biofuel reserva has been als hit Metan about 14 m³ did go up to the vent
[18:13:18] <Jymmm> skunkworks__: Right, but it depends on the mobo, some do, some don't care.
[18:13:41] <Jymmm> skunkworks__: easy enough to test
[18:14:15] <Jymmm> skunkworks__: Then you can isolate sticks vs slots
[18:14:44] <IchGuckLive> all american newsrooms are here in town today i saw a Cnn truck at Burgerking ans NBC at Mc

[18:16:22] <skunkworks__> Jymmm: if I put the 'bad' memory in any other slot - it disables it.
[18:16:48] <skunkworks__> and also scolds me that it isn't 'optimum' memory setup :)
[18:17:03] <skunkworks__> *disables it as bad
[18:17:08] <CaptHindsight> skunkworks_: any BIOS options to config the DRAM?
[18:17:18] <Jymmm> skunkworks__: But does the 'good' memory work in all slots (one stick at a time) ?
[18:17:24] <CaptHindsight> manual config?
[18:18:00] <skunkworks__> CaptHindsight: went as far as updating the bios and firmware.. no change
[18:18:33] <Jymmm> skunkworks__: Dumb question but did you clear the CMOS after BIOS update?
[18:18:45] <CaptHindsight> BIOS exercises them to determine layout and size
[18:19:10] <skunkworks__> Jymmm: yes
[18:19:17] <Jymmm> skunkworks__: K, just checking =)
[18:19:24] <skunkworks__> they call it the nvram
[18:19:38] <CaptHindsight> reading SPD isn't accurate, I wonder what your BIOS does?
[18:20:04] <Jymmm> skunkworks__: Does your ram have a lifetime waranty? Many do
[18:20:15] <skunkworks__> Jymmm: the 'good' memory boots in other slots.. (where the bad memory doesn't)
[18:20:24] <skunkworks__> Jymmm: have to check
[18:20:40] <Jymmm> skunkworks__: Cool, at least you know it's not the mobo that's fubar'ed
[18:20:50] <Jymmm> skunkworks__: what BRAND ram is it?
[18:21:03] <skunkworks__> hynix
[18:21:28] <skunkworks__> it has been running for probably 2 months or more..
[18:22:28] <CaptHindsight> I'd try running them all the lowest speed and slowest timings if BIOS lets you config them manually
[18:22:49] <Jymmm> skunkworks__: Where did you get the ram from?
[18:23:34] <CaptHindsight> after all the usual board flexing pin straightening checking etc etc
[18:24:03] <skunkworks__> it came with the server - it was refurbished from a company that I have had good luck with...
[18:24:39] <skunkworks__> I will get with them.. pretty sure it is all still under warrantee...
[18:24:54] <Jymmm> skunkworks__: Ah, ok.

[22:06:07] <zeeshan> hooray
[22:06:21] <zeeshan> cnc4pc said it wil be sending out my new toroid supply tommo
[22:06:28] <zeeshan> in exchange for the blown smps and working smps
[22:06:57] <Loetmichel> yeah, tioroid can cope with peaks MUCH better
[22:07:36] <zeeshan> well main reason i bought it
[22:07:41] <zeeshan> is if it ever blew up, i could fix it at home
[22:07:45] <Loetmichel> but be careful: a 1200W toroid that is burning because of overheat simply cant be extinguished.
[22:07:45] <zeeshan> cause its a simple circuit
[22:07:59] <Loetmichel> water on it: flames out. water evaporates: flames back on

[22:08:24] <Loetmichel> its unbeliveable how much energy the iron can store ;-)
[22:08:27] <zeeshan> =D
[22:08:57] <zeeshan> this one is 1300W
[22:09:05] <zeeshan> im just gonna fuse it right
[22:09:07] <zeeshan> so it never overheats
[22:09:35] <Loetmichel> it took about 10 minutes in the shower to get it cooled down enough that it only smoked, not reignited ;-)
[22:09:46] <zeeshan> whyd yours go on fire
[22:10:13] <Loetmichel> welding with a 80V servo supply isnt the best idea ;-)
[22:10:32] <zeeshan> lol
