[00:38:55] <terrym> I had some detailed questions, I would like to implement one, DIY.
[00:39:30] <andypugh> You are more likley to find Visteurs on the mailing list.
[00:39:32] <terrym> I will check it.

[00:41:45] <MacGalempsy> reading through the manual, trying to get a relay to reset a fault, but not sure which module to use. any help?
[00:42:10] <andypugh> What does the module need to do?
[00:43:05] <MacGalempsy> andypugh: well, it moreso needs to be a button on the screen to reset
[00:43:40] <andypugh> I am not really understanding the question.
[00:43:41] <MacGalempsy> just unsure of how to go about that
[00:44:44] <MacGalempsy> while testing the amps, the drive occasionally faults, I have all the drives wired to one relay, and want to be able to hit a biutton on the screen to activate the relay
[00:45:05] <MacGalempsy> right now I am manually grounding the drive to reset it
[00:46:51] <Tom_itx> so tie a button to an io
[00:47:41] <MacGalempsy> i got the net command down, but not sure where to get the button to tie to
[00:47:43] <terrym> Sounds like you want the pyvcp,
[00:48:28] <terrym> The Python Virtual Control Panel
[00:48:32] <MacGalempsy> since there are so many interfaces, i got confused

[00:51:26] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/screenshot.png
[00:51:30] <Tom_itx> there's an example of mine
[00:51:47] <andypugh> Temporarily I would be tempted to net reset iocontrol.0.coolant-flood => some IO pin
[00:53:23] <Tom_itx> how would you calculate the speed / feed on an engraving bit since it pretty much comes to a point
[00:53:53] <Tom_itx> i know the speed would be up there
[00:55:07] <andypugh> I guess in theory you would calculate it based on the depth of engagement.
[00:55:10] <terrym> I just run the spindle as fast as it will go and keep the feed slow enough the bit does not snap off.
[00:55:54] <Tom_itx> andypugh, so around .030 diameter?
[00:56:00] <Tom_itx> or thereabouts
[00:56:23] <Tom_itx> that could be a bit deep, i'll run some tests first
[00:56:31] <andypugh> I think terrym has described what folk do in practice.
[00:56:53] <Tom_itx> well that's what i did as well but i wondered if there was a more exact way to figure it
[00:56:59] <andypugh> I have only engraved anything once, and 0.1mm was a good depth.
[00:57:40] <Tom_itx> lettering a new face for my pendant
[00:57:43] <terrym> My engraving was on copper clad fiberglass PCB.
[00:57:46] <Tom_itx> once the bits get here tomorrow
[00:58:54] <terrym> Yes, plural, bits. I wipe out about 3 before figuring out a good feed rate.
[00:59:35] <terrym> Fortunately, I had a box of 10.
[01:00:34] <MacGalempsy> Tom_itx: thanks for the link.
[01:01:37] <Tom_itx> terrym, i've used small bits before:
http://tom-itx.dyndns.org:81/~webpage/etching/mills1.jpg
[01:03:08] <terrym> Then you have a good starting point.
[01:03:25] <Tom_itx> yeah
[01:03:43] <Tom_itx> just kinda wondering what other do
[01:03:53] <terrym> The tip on the engraving tools is so small, it can snap off and at a glance one can not tell it is broken.

[01:44:09] <tjb1> Any of you good with electronics and know a way to reduce noise?
[01:44:17] <jesseg> perhaps so
[01:44:22] <jesseg> what sort of noise?
[01:44:29] <jesseg> Electrical, or audible?
[01:44:48] <Jymmm> tjb1 twisted pair shielding ,etc
[01:44:58] <tjb1> audible
[01:45:03] <tjb1> bluetooth
[01:45:17] <Jymmm> wtf is BT in CNC???
[01:45:17] <tjb1> I am doing something similar to this -
http://blog.avrnoob.com/2013/11/lets-make-wireless-speaker.html with this chip -
http://www.aliexpress.com/item/Free-Shipping-1pc-Bluetooth-stereo-audio-module-wireless-adapted-speaker-amplifier-audio-KRC-86B-V3-3/1458523920.html
[01:45:42] <tjb1> what is gas tank in CNC?
[01:45:45] <tjb1> ;)
[01:45:51] <tjb1> you ever get that replaced?
[01:47:37] <jesseg> tjb1, OK so please clarify, is it when you're playing music there is other sound in the speaker?
[01:47:50] <jesseg> or a constant hiss between songs?
[01:47:50] <tjb1> yes, static and hissing
[01:47:55] <tjb1> always when connected
[01:48:08] <tjb1> if i turn volume up full, it drowns it out
[01:48:23] <jesseg> what drowns what out?
[01:48:30] <tjb1> music on phone
[01:48:42] <jesseg> Music on phone drowns out what?
[01:48:49] <tjb1> the static
[01:49:00] <jesseg> oh, OK, so static doesn't get louder when you turn up music.
[01:49:06] <tjb1> no
[01:49:23] <jesseg> is your speaker amplified, or directly driven by the bt sound chip?
[01:49:42] <tjb1> amplified
[01:49:53] <tjb1> i am running bluetooth into line-in on desktop speakers
[01:50:10] <tjb1> klipsch speakers so they have their own amplification
[01:50:11] <jesseg> Is the chip made for amplified, or is it made to directly drive speakers?
[01:50:32] <tjb1> amplified
[01:51:00] <jesseg> let's see if I can find datasheet
[01:51:05] <tjb1> good luck
[01:51:06] <jesseg> there's a couple possibilities here
[01:51:28] <tjb1> i have 470 uF capacitor across power supply to chip now
[01:52:03] <jesseg> Also try a surface mount or short-leaded 1uF ceramic or mica/foil/tant cap
[01:52:17] <tjb1> 470 + 1 or just 1?
[01:52:22] <jesseg> one of each.
[01:52:37] <jesseg> The 470 is for the lower frequency, and the 1 is for the higher frequency noise
[01:52:43] <jesseg> but I don't think that is your problem..
[01:53:03] <jesseg> So if you can't find a datasheet how do you know whether it's designed for amplified speakers or for directly driving speakers?
[01:53:21] <tjb1> The person I am copying used an amplifier
[01:53:41] <jesseg> and his worked fine?
[01:53:50] <jesseg> was his that exact same PCB unit from ali?
[01:54:14] <tjb1> its the same part number
[01:54:23] <tjb1> doubt the supplier is the same
[01:55:04] <jesseg> Well, you can try adding caps to the input of the PCB, but my guess is that they did not design the board well and/or used underated caps
[01:55:24] <tjb1> got 1uF ready to solder once it heats up
[01:55:54] <jesseg> If there's hiss when you're playing a clean mp3 or whatever, the sound transfer is all digital from phone, over wireless, until it reaches the little PCB at the speaker.
[01:56:03] <jesseg> So the noise has to be coming from within the chip there..
[01:57:42] <tjb1> still a bunch of noise
[01:57:55] <tjb1> would adding the caps to the output somehow do anything?
[01:58:01] <jesseg> how long are trhe leads on the 1uF cap?
[01:58:11] <tjb1> .5"?
[01:58:17] -!- FinboySlick [FinboySlick!~shark@squal.net] has joined #linuxcnc
[01:58:37] <jesseg> I'd try making the leads on the 1uF cap (as well as the 470) as absolutely short as you can. Longer leads have more inductance
[01:58:56] <tjb1> well I cant really get them any shorter and solder
[01:59:07] <jesseg> adding caps to output would reduce the high frequency response, possibly damage the chip if it's a direct PWM output.. but it'd reduce intended sounds as well as the noise.
[01:59:08] <tjb1> not enough hands :P
[01:59:10] <jesseg> oh OK good enough
[01:59:55] <jesseg> The problem is probably in the way the PCB is layed out, and how the audio DAC is set up with insufficient bypass caps right by it
[01:59:57] <tjb1> ground to signal on outputs?
[02:00:04] <jesseg> Huh?
[02:00:10] <tjb1> for the capacitor
[02:00:16] -!- ve7it has quit [Remote host closed the connection]
[02:00:57] <jesseg> It's too late in a long day for me to figure out partial sentences.. Sorry..
[02:01:58] <tjb1> Do I add the capacitor from ground to channel out?
[02:02:05] <jesseg> Nope.
[02:02:23] <jesseg> If you did, it would reduce both high frequency noise AND high frequency music sound. Would sound muddy
[02:02:37] <tjb1> So positive
[02:02:38] <jesseg> Capacitor needs to be connected across power and ground
[02:02:40] <jesseg> yes
[02:04:24] <tjb1> Time to tell seller it is garbage
[02:04:39] <jesseg> yeah I think so
[02:04:42] <jesseg> what did it cost you?
[02:04:50] <tjb1> $15
[02:05:25] <jesseg> hehe including free shipping from china?
[02:05:53] <tjb1> yes
[02:06:02] <jesseg> lol
[02:06:23] <tjb1> oh well
[02:06:33] <jesseg> don't bother the seller. You knew you weren't going to get good quality hifi stereo equipment for $15 delivered from china.
[02:06:39] <jesseg> They probably spent $14 on shipping ;)
[02:06:54] <jesseg> It does *work* - you could use it for a hands free speaker or something for voice.
[02:07:30] <tjb1> Bunch of chinese on the box, I couldn'
[02:07:35] <tjb1> couldn't tell you what they paid

[02:11:26] <tjb1> Well thanks jesseg, I will try to find a higher quality chip
[02:12:04] <jesseg> I made one once with magnetic detents. I took an old stepper motor from a floppy drive, took out all the copper, and put two hall affect sensors phased just right to make quadurature signals. The remaining stepper teeth in there provided the magnetic detents.
[02:12:16] <jesseg> tjb1, sounds like a plan.
[02:12:51] <tjb1> now to attend to the 3d printer which committed suicide printing replacement extruder gears
[02:12:57] <jesseg> hey tjb1
[02:13:10] <tjb1> ?
[02:13:22] <jesseg> it says "Power supply and power amplifier board"
[02:14:08] <jesseg> but that might be another product
[02:14:26] <jesseg> Before giving up, try connecting unit to non-amplifiied speaker or headphones.
[02:14:59] <jesseg> If the PCB is made for non-amplified speakers, its output may be a little noisy at the low level (which you wouldn't notice on non-amplified speakers)
[02:15:30] <jesseg> furthermore, some cheap audio amplifier chips put out unfiltered PWM - which works great with unamplified speakers but very well could create hash sound in amplified speakers.

[05:17:32] <Mr_Mayhem> Well, the larger breakthrough was to update to 2.5.3, but I had to find the deb file, download it to my usb memory stick and copy it over, right click and run it.
[05:17:51] <Mr_Mayhem> One deb file for the doc update too.
[05:17:55] <CHNCguy> the deb file? the source file?
[05:18:02] <Mr_Mayhem> The it simply worked.
[05:18:09] <Mr_Mayhem> Yes, one moment.
[05:18:15] <CHNCguy> k
[05:18:51] <Mr_Mayhem> This is the magical directory from where all good things come:
http://buildbot.linuxcnc.org/dists/lucid/v2.5_branch-rt/binary-i386/
[05:19:17] <Mr_Mayhem> Now you have to choose the right one, like the holy grail in Indiana Jones.
[05:19:30] <Mr_Mayhem> Choose wisely, my friend. No I will tell you.
[05:19:45] <CHNCguy> lol
[05:19:48] <CHNCguy> the last one?
[05:20:05] <Mr_Mayhem> Yep
[05:20:07] <Mr_Mayhem> linuxcnc_2.5.3.78.g5901d68_i386.deb
[05:20:27] <Mr_Mayhem> Then grab the highest english docs too. EN
[05:21:04] <CHNCguy> I recently got an update to use 2.6 or the master file in the buildbot, are u using a lathe or mill?
[05:21:10] <CHNCguy> mill i think it was right?
[05:21:27] <Mr_Mayhem> Mill.
[05:21:41] <CHNCguy> cool, got a video of it running yet?
[05:21:46] <Mr_Mayhem> If you want to call it that. hehe, just the YooCNC 6040
[05:22:31] <Mr_Mayhem> No, I have to get the driver cards first, 2 went south on me. Cheap crap still. Gonna get Leadshine or Geckos.
[05:23:14] <Mr_Mayhem> Note, that's the YooCNC with the new black control box. Still crap, but nice VFD.
[05:23:56] <Mr_Mayhem> linuxcnc-doc-es_2.5.3.77.gbf5e29f_all.deb is the docs latest.
[05:24:11] -!- patrickarlt has quit [Remote host closed the connection]
[05:24:21] <CHNCguy> cool, I have leadshine hybrid servos, almost ready to test them ;)
[05:24:35] <CHNCguy> i have them on the bench running
[05:24:40] <CHNCguy> but not on my machine yet
[05:24:52] <Mr_Mayhem> Here is the page for my machine:
[05:24:52] <Mr_Mayhem> http://www.carving-cnc.com/cnc6040-series/cnc-6040z-s80-new-router-engraver-drilling-and-milling-machine.html
[05:25:04] -!- Nekosan has quit [Quit: later folks...]
[05:26:22] <Mr_Mayhem> The mechanicals are quite decent, the electronics are tossable, ungrounded unshielded spindle, water pump motor needs a tiny ceramic capacitor, vfd seems nice with analog speed, modbus, spindle at speed relay, etc.
[05:26:39] <CHNCguy> cool
[05:26:40] <Mr_Mayhem> What are you running?
[05:26:54] <CHNCguy> I have 2 CHNC lathes and a knee mill
[05:27:38] <CHNCguy> these 2 lathes are my first attempts at linuxcnc
[05:27:38] <Mr_Mayhem> Nice. What kind of things do you make generally?
[05:29:51] <Mr_Mayhem> I am having a go at making some desktop electrostatic loudspeakers. I did some basic prototypes in acrylic, and I was really hooked by the quality of the sound, so I got a bit more serious and redoing a more sophisticated wire design with pcbs and everything.
[05:30:00] <CHNCguy> well, its kinda weird, my hobby is converting machines, no so much making this LOL
[05:30:07] <Mr_Mayhem> heh
[05:30:23] <CHNCguy> I have converted probably 20+ with mach 3
[05:30:45] <CHNCguy> but even being 2 weeks into linux, I like it alot better
[05:31:24] <Mr_Mayhem> Wow, that's a lot of conversions. What is a typical machine look like? Any links?
[05:31:50] <Mr_Mayhem> Yeah, there is a learning curve, but its nice when you get familiar.
[05:32:24] <CHNCguy> I convert industrial machines, ive done haas vf-2, mazak qt 20, lots of cnc routers, a couple of knee mills some lathes
[05:32:37] <CHNCguy> the only record I have is of the ones I am doing now
[05:32:48] <CHNCguy> http://www.cnczone.com/forums/vertical_mill_lathe_project_log/200960-hardinge_chnc_ii_sp_conversion_mach_3_a.html
[05:33:45] <CHNCguy> I initially wanted to convert these to mach 3, but with all the cool things with linux, i decided to go with linux
[05:34:26] <Mr_Mayhem> Yeah, and no fee for the os, or for the app.
[05:34:55] <CHNCguy> yup, my biggest problem with mach 3 was reliability and stability
[05:35:02] -!- chille_ has quit [Ping timeout: 264 seconds]
[05:35:46] <Mr_Mayhem> Wow, you really break them down. Reliability > windows not a realtime os, yeah.
[05:36:20] <Mr_Mayhem> That lathe needs an exorcist. hehe
[05:38:01] <Mr_Mayhem> I guess the refits rely on some way of getting motors on there.
[05:39:02] <Mr_Mayhem> Adapters or whatever. Never did a refit. Might when I actually go to the next machine, but I don't know the specifics on the different strategies.
[05:41:20] -!- zzolo has quit [Quit: zzolo]
[05:42:02] <CHNCguy> lol
[05:42:21] <CHNCguy> well its kinda like jump in
[05:42:47] <CHNCguy> I like retrofits, makes me money, and its a hobby
[05:43:33] <Mr_Mayhem> Yeah. Figure out what is needed. But there are popular conversions too I saw.
[05:44:55] <Mr_Mayhem> It has to be satisfying to see an old machine become alive again.
[05:45:39] <CHNCguy> it is, very much so
[05:45:43] <Mr_Mayhem> A lot of machines like that have some real history.
[05:45:46] <CHNCguy> Im a young guy too :D
[05:45:58] <Mr_Mayhem> Heh, the machine is older than you.
[05:46:08] <CHNCguy> my machines were made in the 80's same time I was born lol
[05:47:14] <Mr_Mayhem> Yeah. Did you ever page through one of those 1960's machine shop how to kind of black and white books? Those guys were so clever. Badass.
[05:47:57] <Mr_Mayhem> I had found a website with tons of that, but I forgot it.
[05:49:30] <Mr_Mayhem> Old school metal shop kind of stuff. They made their jigs for their jigs.
[05:49:42] <Mr_Mayhem> And so on, hehe.
[05:50:43] <Mr_Mayhem> You said you have leadshine drives. Are you happy with that brand?
[05:52:09] <CHNCguy> ya those books are awedsome
[05:52:41] <CHNCguy> I like them, have not used them on my chnc yet, I will in a week or so an see how the fair :D
[05:53:33] -!- LeelooMinai has quit [Read error: Operation timed out]
[05:53:49] <Mr_Mayhem> The tormach mill uses them, 3 phase ones in lieu of servos, because more torque down low rpm.
[05:54:26] <Mr_Mayhem> More torque than servos at low rpm.
[05:54:47] <CHNCguy> yup, thats why I got them
[05:54:50] <Mr_Mayhem> I forget if they have encoders and feedback or not.
[05:55:00] <CHNCguy> mine do
[05:55:07] <CHNCguy> and autocorrect just like servos
[05:55:35] <Mr_Mayhem> Wow, so you get to figure out the servo loop tuning process. I so want to play with that.
[05:55:58] <Mr_Mayhem> I guess its the best of both worlds.
[05:56:25] -!- LeelooMinai [LeelooMinai!~quassel@184.175.46.197] has joined #linuxcnc
[05:58:17] <CHNCguy> I think it is, the software auto tunes
[05:58:24] <CHNCguy> ;D
[05:58:45] <MacGalempsy> have you had luck with autotune?
[05:59:57] <CHNCguy> for my hybrid steppers/servos?
[06:00:22] <Mr_Mayhem> Don't you still have to put them on the machine first?
[06:00:35] -!- FreezingCold has quit [Ping timeout: 260 seconds]
[06:00:37] <CHNCguy> mine come already tuned out of the box
[06:01:10] <Mr_Mayhem> Are they the kind where the control is built into the end of the motor, or external boxes?
[06:01:12] <CHNCguy> I can hook it up to the machine and then fine tune them, but I don't it will be necessary, my travel on my machines are kinda small
[06:01:30] <CHNCguy> external drive
[06:01:45] <CHNCguy> I would not want the drive to be on the machine...
[06:01:51] -!- Fox_Muldr has quit [Ping timeout: 252 seconds]
[06:02:11] <Mr_Mayhem> I see, coolant and flying chips, etc.?
[06:02:40] <CHNCguy> yup, and operators/people LOL
[06:03:47] -!- Fox_Muldr [Fox_Muldr!quakeman@frnk-5f746c35.pool.mediaWays.net] has joined #linuxcnc
[06:03:49] <Mr_Mayhem> So the dynamic differences of loaded or not does not affect the tuning parameters much?
[06:04:09] <Mr_Mayhem> They just come pre-tuned? Or maybe have to redo it?
[06:04:40] <CHNCguy> well, the inertia of the motor is importantfor tuning
[06:05:08] <CHNCguy> and final tune could be done, but thats the main point that needs to be tune IMHO
[06:05:49] <CHNCguy> but I don't think I will need to final tune it
[06:05:52] <CHNCguy> we will see ;D
[06:08:18] <CHNCguy> so where u at mayhem? Im in floida ;)
[06:08:41] <Mr_Mayhem> I was in florida, now las vegas, nv.
[06:08:54] <Mr_Mayhem> I did Orlando area for a while.
[06:08:58] <CHNCguy> Thats where we moved from lol
[06:09:02] <Mr_Mayhem> hehe
[06:09:08] <CHNCguy> nice
[06:09:11] <Mr_Mayhem> I hear a lot of that.
[06:09:23] <Mr_Mayhem> The two vacation cities.
[06:10:25] <CHNCguy> yup ;)
[06:10:27] <Mr_Mayhem> I figure some day I will see who is around doing cnc stuff. For now I am just getting the cnc thing going so I can cut speaker parts.
[06:11:02] <CHNCguy> cool, so just hobby for ya?
[06:11:14] <Mr_Mayhem> I have an electronics/software background, not machine stuff.
[06:11:37] <Mr_Mayhem> Yes and no. I want to make it my main thing, but now is just a hobby.
[06:11:49] <CHNCguy> haha, im an RN, soon to be Nurse Practitioner LOL
[06:12:14] <Mr_Mayhem> Hehe, now that is some role dynamic range.
[06:12:30] <CHNCguy> useto be EE
[06:12:41] <Mr_Mayhem> Those folks make money. General or specialised?
[06:12:49] <CHNCguy> Psych NP
[06:13:01] <CHNCguy> I like drug and detox
[06:13:02] <Mr_Mayhem> Wow, I have a best friend who does that.
[06:13:30] <Mr_Mayhem> She tells me often of her daily happenings.
[06:13:37] <CHNCguy> haha, ya its fun :)
[06:13:44] <CHNCguy> Crazy, but fun
[06:14:07] <Mr_Mayhem> Lots of drama. Like when they get put in to the hospital, but walk out and everyone is searching for them....
[06:14:12] <Mr_Mayhem> hehe
[06:14:36] <CHNCguy> haha ya been there haha
[06:15:01] -!- terabyte- has quit [Quit: terabyte-]
[06:15:27] <Mr_Mayhem> I heard some folks doing tele-medicine via video link. That sounded like maybe less stress, but the pay is usually tied to being there and running a daily thing.
[06:16:10] <CHNCguy> ya insurance companies are crazy, so many stipulations for reimbursement
[06:17:10] <CHNCguy> I would really like to design and market my own cnc lathe
[06:17:24] <Mr_Mayhem> Nevada just allowed nurse practicioners to run their own practice without needing a supervising doctor. They feel liberated. The doctors are like, yeah, good luck with that idea.
[06:17:47] <Mr_Mayhem> There are so many mills out there, but maybe not so many lathes in the diy/hobby world.
[06:18:24] <CHNCguy> Ya, I want a MD to cover my ass, if I wanted to be a doc I would have gone to med school LOL
[06:18:39] <CHNCguy> I like working with someone who knows more, (supposedly)
[06:19:08] <Mr_Mayhem> Often the doc is the greater idiot, and it's the nurse who knows their shit.
[06:19:29] <CHNCguy> I second that statement....
[06:20:23] <Mr_Mayhem> The schooling emphasis creates that difference. Different focus.
[06:20:57] <CHNCguy> true
[06:21:11] <Mr_Mayhem> So what kind of lathe do you think the market needs?
[06:21:22] <CHNCguy> so ur mill got a tool changer?
[06:22:19] <Mr_Mayhem> No, but it could for like $8000.00. For that I could buy like 5 of the original machine. There are 80mm spindles with toolchanger head.
[06:23:03] <Mr_Mayhem> But they are crazy expensive. and I would lose precious z height, of which I have only 60mm.
[06:23:28] <CHNCguy> wow thats not alot :S
[06:23:38] <Mr_Mayhem> It an entry level router mill.
[06:23:58] <CHNCguy> gotta start somewhere :D
[06:24:06] <Mr_Mayhem> The real value I suppose is that I learned all the basics on it.
[06:24:13] <Mr_Mayhem> yeah.
[06:24:54] <CHNCguy> true true
[06:25:06] <Mr_Mayhem> I have to go for a bit, nice chat.
[06:25:09] <CHNCguy> well im off to bed, see ya later mayhem and the linuxcnc crew

[19:12:02] <jdh> my current router is very slow. I was hoping the 3020 would be speedier
[19:12:07] <archivist> jdh, do you have a rotary axis?
[19:12:37] <jdh> nope
[19:13:09] -!- jfire has quit [Quit: Leaving.]
[19:13:16] <archivist> you can hide all your backlash issues to make encoder wheels with a rotary with unidirectional g code
[19:15:43] <jdh> the wheel was just an example. My initial goal for a cnc machine was to make PC boards
[19:16:07] <jdh> which I've come to understand is not a great method, but I would still like to do so.
[19:18:04] <archivist> you need ballscrews or proper backlash control for high resolution work
[19:18:29] <archivist> sprung nuts can be enough for that sort of light work
[19:18:47] <jdh> fixing my current router with better bearings, screws, nuts would be prohibitive.

[20:37:28] <asah> hello andy, your posts are quite enlightening.
[20:37:31] <Tom_itx> what is the 5i23?
[20:37:33] <andypugh> I have auto gear detection on my mill. It's working well.
[20:37:35] <asah> good to meet you.
[20:38:11] <asah> cool. I am not quite at the changer level yet. still getting the basics up.
[20:38:43] <andypugh> http://linuxcnc.org/dapper/index.php/english/forum/47-hal-examples/27071-automatic-spindle-gear-detection
[20:39:16] <asah> I have my smartserial io cards hooked up (7i70 and 7i71) and working on getting my 7I83 servo out card going
[20:39:47] <skunkworks> I was always going to have the K&T check the spindle encoder vs the spindle motor encoder and check to make sure it was in the right gear - but we have had 0 missed shifts so far
[20:40:17] <Tom_itx> don't fix it if it ain't broke
[20:41:22] <asah> andypugh: cool. the shifter on my maho is a bit complex, ill be pretty happy when I have it just shifting to each of the gears. your auto solution looks like a nice way to go on top of that though... bookmarking for later.
[20:41:45] <asah> I am looking for example ini files using smart serial devices
[20:42:18] <asah> that I can use as a launchingboard.
[20:42:22] <andypugh> I don't think I touch the INI with my configs.
[20:42:42] <andypugh> It all ends up in HAL.
[20:43:06] <Tom_itx> i don't think you do either
[20:43:27] <andypugh> What you can do is connect everything up, then run some command-line HAL to figure out what pins you have.
[20:43:32] <Tom_itx> asah do you have a board that supports sserial?
[20:43:41] <Tom_itx> ^^ what he said
[20:43:51] <Tom_itx> halcmd show pin
[20:43:51] <asah> yes I do
[20:44:00] <Tom_itx> will get you goin
[20:44:07] <andypugh> halrun // loadrt hostmot2
[20:44:13] <andypugh> loadrt hm2_pci
[20:44:15] <asah> ok. ill play with that. it will all autoconfigure? =)
[20:44:15] <andypugh> show pin
[20:44:23] <Tom_itx> yes
[20:44:54] <Tom_itx> the sserial io just shows up once it's connected
[20:45:00] <skunkworks> asah,
https://www.youtube.com/watch?v=E0rVbVixMw8
[20:45:04] <andypugh> The hardware will auto-conf. You need to decide how to connect the pins.
[20:45:31] <andypugh> You might want to conside loadrt hostmot use_serial_numbers=1
[20:45:53] <asah> I am seeing encoder ins and stepgen outs.
[20:46:30] <asah> 4 channels of pwm etc. those are all defaults for hostmot2 right?
[20:46:39] <asah> I don't have any encoder ins for instance.
[20:46:45] <andypugh> If that is all you see then it probably means that the sserial boards are not powered.
[20:47:18] <asah> ok.
[20:50:36] <andypugh> You probably just need to set jumpers for cable power in a few places, and supply 5V to the 7i44 (if you are using a 7i44)

[21:03:21] <andypugh> So, the 7i44 is powered from the 5i23, and the 7i70 is powered separately?
[21:03:30] <asah> yes
[21:04:34] <andypugh> I think my stuff is all the other way round, wit the 5V feed to the 7i44 powering the serial peripherals via the cables. (I suspect that doesn't work with a 7i70)
[21:05:08] <asah> I wish the 7i44 had some leds on it.
[21:05:28] <asah> I setup the debug flags on loadrt hostmot2 and see sserial 0
[21:05:31] <asah> so none are found.
[21:05:39] <andypugh> Is the 7i70 in "operate" mode on the jumpers?
[21:06:01] <asah> need to give it a firmware though.
[21:06:03] <asah> looking...
[21:06:59] -!- jfire has quit [Ping timeout: 252 seconds]
[21:07:31] <andypugh> 7i70 shouldn't need firmware.
[21:09:18] -!- PCW [PCW!~chatzilla@99.88.10.65] has joined #linuxcnc
[21:09:52] <asah> yes, 7i70 is in OP mode
[21:11:16] <PCW> if its got 5V and field power (and is connected to a sserial port) it should just work
[21:11:43] <PCW> what LEDs are on on the 7I70
[21:12:39] <asah> cr33, cr9
[21:13:18] <asah> sorry, cr36 c68
[21:13:32] <PCW> yellow and red?
[21:13:34] <asah> sorry again... cr36 cr8
[21:13:40] <asah> yes
[21:14:14] <PCW> OK thats right (with no comms)
[21:14:44] <PCW> what is the hostmot2 config line in your hal file
[21:15:22] <asah> hi peter... =)
[21:15:47] <asah> I tried with no config line
[21:16:09] <asah> then just loaded the firmware for SVST4_8.BIT
[21:16:09] <PCW> needs one
[21:16:34] <andypugh> I have been using the 5i25 too much
[21:16:38] <andypugh> You need :
[21:16:46] <andypugh> loadrt hostmot2
[21:17:13] <andypugh> loadrt hm2_pci config="firmware=SVST4_8.BIT"
[21:17:40] <andypugh> Except, SVST4_8.BIT has no smart-serial modules, and that is probably the issue.
[21:17:41] <asah> still get sserial: 0
[21:17:45] <asah> ok.
[21:17:51] <PCW> 1. needs firmware with sserial that matches your 7I44
[21:17:51] -!- |1li has quit [Ping timeout: 240 seconds]
[21:17:52] <PCW> 2. needs a sserial config line (my experience is that it does not work without this)
[21:17:53] <asah> is there a known one that does?
[21:18:11] -!- arkgis has quit [Remote host closed the connection]
[21:18:22] <asah> known firmware that is.
[21:18:35] <asah> I could use the Fabs one we hacked on a few months back.
[21:18:38] <PCW> the one you had with fanuc did
[21:19:16] <PCW> what actually do you want on the config?
[21:19:54] <asah> this is the setup I emailed you about.
[21:20:25] <andypugh> I have one for 7i44 + 7i49 + 2 x 7i39. I doubt you want that one really though :-)
[21:20:28] <asah> I am still no pro with linuxcnc, so I am unsure which components get configured where, what needs to be pushed into firmware, vs configured later"
[21:20:52] <asah> andy, that one is close to what I need actually.
[21:21:48] <asah> basically I want to use the 7i70 and 7i71 for IO. and the 7i83 for servo +- control
[21:21:49] <andypugh> You need to load a firmware into the 5i23 (from the loadrt hm2_pci line) which puts the right things on the right headers. (though you can generally plug the harware to suit the firmware, rather than the other way round)
[21:21:52] <asah> 10V control
[21:24:15] <asah> PCW, I tried that firmware and now I can see sserial devices.
[21:24:20] <asah> had to move cables around
[21:24:21] <PCW> using a 7I83 (sserial +- 10V servo interface) means that you need at least sserial ports if you
[21:24:22] <PCW> want them connected to a 7I44, and you want encoders that will be a SVSS config of some type depending
[21:24:24] <PCW> on the encoder daughtercard
[21:24:50] <PCW> Yeah you need sserial firmware for sserial devices :-)
[21:25:01] <asah> yeah yeah.
[21:25:21] <Tom_itx> andypugh did you see my bitfile builder page?
[21:25:23] <asah> hard to know if it is missing in the firmware or if it is because of my devs not plugged in etc.
[21:25:54] <asah> PCW: yes I want them connected to a 7i44, I just bought the encoder card you recced.
[21:25:56] <andypugh> I have an SVSS6_8 here, does that sound right?
[21:25:56] <andypugh> Tom_itx: No, I didn't.
[21:26:08] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/emc/xilinx/xilinx14_install_index.php
[21:26:14] <Tom_itx> you should have a crack at one
[21:26:22] <asah> so I show a single sserial device.
[21:26:27] <Tom_itx> see if the directions work
[21:26:36] <asah> SSerial 1:
[21:27:08] <andypugh> Looks handy. What I think might be useful would be a simple web page that lets you configure the required pinout, then emails you the requested bifile when done. :-)
[21:27:27] <Tom_itx> heh
[21:27:41] <andypugh> I have built a few bitfiles with the tools in the LinuxCNC version fo Hostmot2
[21:27:41] <asah> only sees the 7i71, not the 7170.
[21:27:56] <asah> probably cause the FABS.BIT is hacked,
[21:28:41] <PCW> maybe wrong channel?
[21:29:07] <PCW> ISTR that 4 channels were Fabs and 4 were sserial
[21:29:32] <alex_joni> PCW: hi
[21:30:03] <asah> PCW your memory is better than mine!
[21:30:13] <PCW> I kind of wish that the driver would list the sserial pins (even if unused)

[21:37:31] <flughafen> that is something to think about too

[22:33:25] <cradek> an arc with F=0 would be an error in linuxcnc
[22:40:01] <asah> why do my hostmot2 pins say DIR IN when they are analog outs?
[22:41:36] <asah> seems to work ok
[22:42:37] <JT-Shop> something is draining the battery down on my GL1800. I disconnected the negative wire from the battery and connected my Fluke 77 to 300ma input then connected to the negative terminal and the ground wire
[22:42:48] <ries> cradek: yup, thought so already.
[22:42:51] <JT-Shop> the meter read 3.25, is that 3 ma
[22:43:05] <JT-Shop> I've never measured ma on the meter :(
[22:43:47] <asah> seems like the 7i83 does not put out voltage on the enable pins when its hi?
[22:44:46] <asah> enable seems to shut the voltage on and off on the corresponding analog out pin, but it doesn't seem to be changing the pin voltage (of the enable pin)
[22:46:18] <Tom_itx> JT-Shop any radio etc on standby?
[22:46:40] <Tom_itx> that's barely enough current to light an led
[22:50:31] -!- FinboySlick has quit [Quit: Leaving.]
[22:52:38] <andypugh> asah: I think you need to view the "enable" outputs as switches.
[22:52:57] <andypugh> They allow current to pass when on.
[22:54:28] <andypugh> So, a typical connection would be +5V to the high side of the drive opto, then - side of drive opto to ENA0+ then ENA0- to ground.
[22:55:09] -!- WalterN has quit [Ping timeout: 246 seconds]
[22:55:44] <andypugh> This is an advantageous scheme, as it means that the enable outputs are fully isolated.
[22:55:51] -!- mshaver has quit [Ping timeout: 246 seconds]
[22:56:10] <andypugh> "Six uncommitted OPTO coupler outputs are available for drive enable use. The ENA outputs are floating switches so can be used for active high and active low drive enables. Output rating of the switches is 50 mA max at 100VDC max . Note that the enable outputs are polarized and can be damaged with reverse polarity. For active high drive enables. ENAN+ should go to the appropriate positive power supply and ENAN- to the driv
[22:56:11] <andypugh> enable input. The drive enables also control the analog out. When a channel is disabled, its cooresponding analog output is forced to 0V."
