[00:01:34] <Paragon39> ds3: this may answer your question http://www.thinktink.com/stack/volumes/voli/store/mechmill.htm
[00:03:23] <Paragon39> It mentions 0.005" separations are common.
[00:03:39] <ds3> Hmmmm

[00:07:33] <JT-Shop> Paragon39: I hope you left him some nice feedback
[00:07:53] <Paragon39> LOL... You Bet ;-)
[00:07:54] <atom1> JT-Shop do you have a 7i43?
[00:07:56] -!- robh__ has quit [Ping timeout: 240 seconds]
[00:08:01] <JT-Shop> no
[00:08:07] <atom1> :/
[00:08:09] <JT-Shop> 5i20's
[00:08:17] <Paragon39> I do!
[00:08:23] <atom1> trying to figure out the geneder of the parport plug
[00:08:28] <atom1> gender*
[00:08:43] <ds3> given the costs of those bits, using a service is still cheaper
[00:08:58] <JT-Shop> I dug through my computer junk and found one for the D510MO
[00:09:00] <Paragon39> atom1: gender?
[00:09:13] <atom1> also, as i read the 7i47 will plug right into the 7i43
[00:09:21] <atom1> Paragon39 is it male or female
[00:09:30] <atom1> the DB25
[00:10:07] <Paragon39> Well the one I got from messa has a male DB25 (pc end) and an IDC on the card.
[00:10:24] <atom1> ok
[00:11:03] <Paragon39> Aren't all pc parport female?
[00:11:33] <atom1> yep
[00:11:38] <Paragon39> ds3: Not here in the UK!
[00:12:03] <atom1> so the cable is a male to female
[00:12:15] <atom1> parport cables are harder to find nowdays
[00:12:22] <ds3> Paragon39: you don't have the $60, 2-3 day service?
[00:12:59] * JT-Shop goes to walk the dog as I've run out of insulation itch, itch, itch
[00:14:39] <Paragon39> atom1: The cable is a ribbon cable with a single maile db25 connector on one end and an IDC female connector on the other (Like on a hard drive).
[00:15:10] <Paragon39> The IDC plugs into the 7i43.
[00:16:00] <Paragon39> ds3: $60 how many cards for that?
[00:16:50] <ds3> 3
[00:17:13] <ds3> I think it is 3"x4" panels
[00:18:17] -!- ve7it has quit [Remote host closed the connection]
[00:19:10] <Paragon39> ds3: The think & tinker cutter is only $9 and can cut 100's especially if using the cheaper paper based boards. Sure if you have a board that you want to mass produce out source it but there is no comparison for DIY. Made a mistake make changes and cut again...
[00:20:14] <ds3> Paragon39: I guess I have enough stuff to worry about then adding to it with possible PCB problems
[00:20:57] <Paragon39> Sure thing, it's all horses for courses :-)
[00:22:34] <ds3> FR4.. the paper based stuff blah
[00:22:45] <ds3> enough dreaming about a miracle
[00:22:54] <atom1> Paragon39 what are you using the 7i47 for?
[00:23:15] <Paragon39> 7i43?
[00:23:38] <atom1> mmm, maybe you don't have one
[00:23:48] <atom1> i was gonna use it for a buffer board
[00:23:57] -!- ve7it [ve7it!~LawrenceG@S0106009027972e37.pk.shawcable.net] has joined #emc
[00:24:37] <Paragon39> Oh that's the interface board right?
[00:24:48] <atom1> rs422
[00:25:02] <atom1> but i was gonna use it mainly for isolation
[00:27:14] <Paragon39> The board I was just showing I designed for isolation with the 7i43 in mind. I also made two boards that connect to the 50way IDC connectors on the 7i43 which convert them to screw terminal.
[00:27:48] <atom1> oh did you get those back?
[00:27:55] <atom1> or did you mill it yourself
[00:29:38] <Paragon39> Milled them myself. I based them on these cards. I used Eagle with pcb-gcode and EMC http://www.anderswallin.net/2010/01/mesa-5i20-breakout-boards/
[00:30:07] <atom1> what brand screw terminals did you get?
[00:30:17] <atom1> i think tyco are about the cheapest
[00:31:19] <Paragon39> Yeah I think they were tyco.. I got them from here http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&item=120690830845&ssPageName=STRK:MEWNX:IT
[00:31:53] <atom1> those aren't the .1" spacing are they?
[00:32:12] <atom1> more like .506mm or so
[00:32:39] <Paragon39> Yes .506mm...
[00:32:55] <atom1> you can get .1" ones you know
[00:33:35] <Paragon39> .1" what that in mm?
[00:33:43] <atom1> 2.54
[00:33:50] <Paragon39> can's find my calculator
[00:34:22] <atom1> http://tom-itx.dyndns.org:81/~webpage/boards/atmega32_exp1.jpg
[00:34:28] <Paragon39> Tha's a nicer size!
[00:34:29] <atom1> there's a 3pin one on that board
[00:34:34] <atom1> lower left
[00:34:47] <Paragon39> taking a look
[00:34:55] -!- warlock has quit [Ping timeout: 246 seconds]
[00:35:39] <atom1> ebay doesn't have any though
[00:36:21] <Paragon39> Now they are nice and compact. I was looking at 3mm but they were working out more expensive so I went with the 5mm pitch. I needed a lot for some other projects.
[00:36:43] <atom1> i think they interlock too
[00:36:45] <atom1> side by side
[00:37:04] <atom1> i suppose that's a brand specific thing
[00:37:10] <Paragon39> Yes they do.
[00:38:39] <Paragon39> Heres an opto isolator card too http://www.anderswallin.net/2006/08/optoisolator-cards-for-mesa-5i20-servocard/
[00:39:59] <atom1> http://search.digikey.com/scripts/DkSearch/dksus.dll?lang=en&site=US&KeyWords=277-1274-ND&x=19&y=20
[00:40:08] <atom1> that's phoenix but i'm sure you can get them in tyco
[00:40:13] <atom1> cheaper
[00:40:49] <Paragon39> Wow $1.70 each!
[00:40:59] <atom1> phoenix is always higher
[00:42:25] <Paragon39> cant beat that pack of 10 for a quid :-)
[00:43:54] <atom1> i always add in things like board cost when making one
[00:44:03] <atom1> but yeah those are a good price
[00:45:13] <atom1> i gotta make sure i have a good source for parts though too
[00:47:26] <Paragon39> Right! Nothing like a good source ;-)
[00:48:02] <Paragon39> Anyways it's 01:47 here and I need my beauty sleep... lot's of it some will tell you ;-) Nite

[03:33:01] <ssi_> lul
[03:38:12] <ssi_> KimK: are you around, perchance?
[03:38:29] <KimK> ssi_: Hi
[03:39:07] <ssi_> wow!
[03:39:17] <ssi_> although I found it in backscroll :D
[03:39:22] <ssi_> HeeksCNC
[03:39:27] <ssi_> was trying to remember what you had said
[03:40:27] <KimK> I think there's some canned install for it, but I forgot what right now, let me see if I can tell what (older) version I have.
[03:40:31] <ssi_> aw, it's windows
[03:40:44] <ssi_> when I looked at it yesterday, I got the impression it was unix
[03:40:52] <ssi_> I need to find something halfway decent to use in osx
[03:41:56] <KimK> ssi_: CAM?
[03:42:05] <ssi_> cad would be fine for now
[03:42:28] <KimK> 2D? LibreCAD is available for OS/X
[03:42:51] <jdhNC> draftsight
[03:42:54] <KimK> Ries' Qt4 fork of Qcad free
[03:43:17] <tom3p> join #cam to talk to people using HeeksCad & HeeksCNC
[03:44:16] <ssi_> downloading draftsight
[03:44:28] <KimK> Ha, I installed that draftsight beta. I finally pulled it. Two problems: 1) not free, you're done using it when they say so. 2) It grabbed a bunch of unrelated file assocs and goofed them up. Md5sum, var, all kinds of odd stuff, drove me nuts.
[03:44:39] <ssi_> haha ok
[03:45:28] <jdhNC> I use it in windows because it loads 5x faster than autocad
[03:45:41] <KimK> About 1-2 icons in every screenful became draftsight icons.
[03:46:26] <ssi_> gross
[03:46:39] <ssi_> librecad incoming
[03:46:45] <KimK> If you don't have to have dwg *right now*, I'd recommend LibreCAD and patince. You may yet find dwg in LibreCAD.
[03:46:58] -!- Athlocatle [Athlocatle!~vip0@] has joined #emc
[03:47:06] <KimK> s/patince/patience/
[03:47:07] <ssi_> all I'm looking to do is make up some toolpaths to use with a roughing cycle
[03:48:27] <KimK> OK, for that, you'll do fine with LibreCAD/Qcad. It's DXF format, 2000, I think? It offered two, maybe 2000 and R12?
[03:49:46] <ssi_> ahaha I like the default units dropdown
[03:49:51] <KimK> It's a little counterintuitive until you get onto their way of doing things, then it's easy. It's pretty manual, though, helps if you have a good grasp of geometry for construction lines.
[03:50:36] <KimK> Be sure to create plenty of layers (upper right sidebar), don't let everything pile up into layer 0 (default)
[03:51:04] <KimK> I always create a construction layer so I can shut it off later.
[03:52:01] <KimK> The "eyes" make it visible/invisible, the padlocks make it writeable/protected
[03:52:24] <ssi_> work bought me a new 17" mbp
[03:52:26] -!- tom3p has quit [Ping timeout: 264 seconds]
[03:52:37] <ssi_> I'm hoping I can avoid having to put parallels + solidworks on it :P
[03:53:44] <KimK> Well, if you're used to SolidWorks you might find LibreCAD a little rudimentary, but try it and see what you think.
[03:54:31] <ssi_> heheh yeah, maybe

[03:58:59] -!- xcncx has quit [Client Quit]
[04:00:27] <KimK> Also, I like to keep all lines at zero width for accuracy while drawing, and then when ready to print, increase just the finished object layers to .015 or .018 or whatever it is, to make them easily visible/printable without issues. Some printers print zero-width lines exactly that way. "Problem? What problem?"

[04:02:24] <KimK> I'll let you get acquainted, call me if you need anything.
[04:02:31] <ssi_> thanks
[04:03:47] <KimK> Oh, and you can select objects and then edit the selection to move them to another layer.

[04:13:34] <KimK> ssi_: If LibreCAD isn't to your liking, I did find this for HeeksCAD and OS/X: http://code.google.com/p/heekscad/wiki/CompilingForMacOSX Compiling it looks like a lot of work, but maybe that's just me.
[04:15:32] <KimK> ssi_: I seem to recall that Andy built HeeksCNC for Mac, maybe you can ask him about it in a couple weeks.
[04:16:32] <ssi_> oh that's right, andy's mia for awhile
[04:16:36] <ssi_> no wonder it's been so quiet around here :D

[08:46:15] <mrsunshine_> dammit,. just remembered i havent oversized the pattern
[08:46:35] <mrsunshine_> oh well, hope it will be good enough in the end anyways, not a biggie as i can machine out some allowance for the pulleys etc =)
[08:53:02] <mrsunshine_> i wanna be able to make cores tho =) would be neat to be able to utalize some more =)

[13:24:50] <Valen> for a desktop to use for work core2 for a single task machine atom
[13:24:58] <Valen> for emc atom works well
[13:25:06] <Valen> it was just a bit light on the desktop
[13:25:59] <archivist> "whatever" is the wrong answer when asking for an informed choice

[15:44:29] <robin_sz> /me looks
[15:44:48] <robin_sz> I never did like desktop mills ...
[15:45:08] <archivist> swarf, and lots of it
[15:45:21] <robin_sz> looks a big beast anyway
[15:46:11] <robin_sz> you'll be needing a decent swarf conveyor for that
[15:46:22] <skunkworks> another thing that needs to be installed.
[15:46:36] <skunkworks> we have 2 - need to make 1 good one out of it.
[15:46:43] <robin_sz> I used to make lots of those
[15:46:50] * anonimasu draws a toolchanger
[15:47:12] <robin_sz> probably a bit big for that though
[15:47:18] <skunkworks> We are need to install the apron on the left side of the sadle too. now that I see that..
[15:47:42] <robin_sz> should be quite an animal when its done

[15:49:06] <skunkworks> anonimasu: don't know - making a lot of projects for me at the moment :)
[15:49:56] <anonimasu> like machine v8's out of solid?
[15:50:07] <skunkworks> heh - not yet
[15:50:21] <skunkworks> robin_sz: what have you been up to?
[15:51:28] <robin_sz> mmm, I got a bit busy having an engineering business
[15:51:39] <robin_sz> but, the recession came along and saved me from that
[15:51:46] <robin_sz> back doing software again now
[15:51:46] <skunkworks> yeck
[15:52:54] <robin_sz> biggest swarf conveyor we built was for BAE at brough
[15:53:22] <robin_sz> they make slightly large bits of ally

[15:53:48] <robin_sz> wait, not brough, it was their plant on that airfield ... hmm
[15:53:56] <skunkworks> you can see the chip conveyor coming out on the left side of the machine.
[15:53:57] <skunkworks> http://electronicsam.com/images/KandT/oldkandt.JPG
[15:54:13] <robin_sz> anyway, they were making wing spars for the A380
[15:54:26] <robin_sz> i think the conveyor was 40m long
[15:54:29] <skunkworks> it gets cut off in the photo far right.
[15:54:36] <skunkworks> cool
[15:55:01] <anonimasu> parquette floor :D
[15:55:03] <robin_sz> yep, we used to make a lot about that size
[15:55:24] <anonimasu> where do they expect chips to go :)
[15:56:33] <robin_sz> we used to do a lot for these people: http://www.fse.co.uk/
[15:57:01] <robin_sz> we built hundreds of units for them, typically about 2m x 3m with a conveyor
[15:58:16] <skunkworks> anonimasu: between the table and the up-right (between the x/z table and y axis) the chips fall into a gap that will have a conveyor at the bottom
[15:59:19] <robin_sz> coolant filtration is the key ;)
[16:01:06] <robin_sz> we used to do a lot of settling tanks with weirs ... a hole at the bottom so oil that floated on top could not get through, then an overflow weir, so particles stayed on the bottom, repeat a few times and you have it sorted

[16:23:05] <aggrav8d> good morning!
[16:23:07] <cradek> in general you have two options: write a tool table entry with G10 and then use G43, or else use G43.1 directly without a tool table entry
[16:23:42] <lilalinux> thank you
[16:23:48] <cradek> welcome
[16:24:13] <cradek> there are other approaches but those are the two good ones I think
[16:26:27] <aggrav8d> kimk, are you here?
[16:26:47] <lilalinux> "To use a tool length offset from the program, use G43.1 Xn Yn ... Wn to set any axis tlo at run time. "
[16:26:57] <KimK> aggrav8d: I'm here
[16:27:03] <lilalinux> what is X Y there for?
[16:27:27] <cradek> lathes, multi-spindle machines, etc etc
[16:27:39] <aggrav8d> I've been reducing the speed of my machine to stop losing steps. I think I might still have a problem on Z but I'm not sure. when I ran tort.nc and checked Z I think it was *slightly* higher than before (easier to fit a piece of paper underneath)
[16:28:01] <aggrav8d> also discovered a nasty spot where my machine was binding on one axis and that's halved the speed on y. :P
[16:28:41] <KimK> All sounds reasonable. Any other news?
[16:29:03] <aggrav8d> well now i'm wondering how to be sure that the z problem is PEBKAC, not machine.

[16:30:36] <anonimasu> cylindet to move the atc in sits and drives the ear on the yellow part...
[16:31:04] <KimK> Your machine has the high-pitch-multistart screws on X/Y, correct? Tell us about your Z screw arrangement.
[16:33:27] <aggrav8d> multistart screws? only on Z.
[16:33:32] <aggrav8d> 5 start, 2tpi screw.
[16:33:39] <aggrav8d> XY are both chain drive.
[16:36:29] <KimK> Oh, that's right. OK, I had it backwards then. So, 2 tpi on Z, and is that a ballnut or some kind of threaded plastic bushing?
[16:37:09] <aggrav8d> plastic, yeah.

[16:38:44] -!- isssy has quit [Ping timeout: 240 seconds]
[16:40:02] <KimK> OK. Oh, anti-backlash, interesting. How hard is the screw to turn by hand, with the router hanging on it? (And not counting motor drag).
[16:40:26] -!- nullie has quit [Quit: Ex-Chat]
[16:42:13] <KimK> I guess what I'm asking is what is the difference in feel between turning the Z screw CW vs. CCW. I'm trying to get a feel for how much gravity load is being reflected back in your setup.
[16:42:41] <aggrav8d> well i can't give you newtons. i can grab the shaft collar and turn it by hand when the machine is powered off.
[16:42:53] <aggrav8d> with thumb and index, in fact.
[16:43:27] <KimK> OK, that's a good thing. How about the difference between CW and CCW?
[16:45:44] <aggrav8d> well, sure. one way gravity works in my favor.
[16:45:59] <aggrav8d> but i can turn it either way.
[16:47:03] <KimK> OK, and is it say, 10% difference? 50% difference?
[16:47:09] <jdhNC> it would be cool if you could turn gravity either way.
[16:48:02] <KimK> jdhNC: Great idea! aggrav8d, hold the router table upside down over your head and then try it, lol
[16:49:32] <aggrav8d> i really couldn't say how much of a difference. it's noticably different.
[16:50:02] <aggrav8d> I suspect the problem is one of varying material thickness and user error when homing z.
[16:50:20] <aggrav8d> i'm willing to check everything just in case.
[16:50:33] <KimK> aggrav8d: OK, that's close enough for now. And how about the motor size and gearing? Is that a nema 23 stepper?
[16:51:03] <mrsunshine_> aw, how fast a perfect casting can become a non perfect
[16:51:09] <mrsunshine_> noticed a little hole in the side ...
[16:51:14] <mrsunshine_> well its hollow! :P
[16:51:20] <mrsunshine_> no wonder it didnt sink anywhere
[16:51:26] <mrsunshine_> it had as much metal as it wanted in that part :P
[16:51:40] <aggrav8d> yeah, nema23.
[16:52:14] <mrsunshine_> would have to have a raiser big as a house to feed the casting with material :/
[16:53:24] <KimK> mrsunshine_: Well, at least you know where you can get some metal to do a remelt. Sorry it didn't work out, better luck next time.
[16:54:04] <mrsunshine_> KimK, dont realy think its a problem tho, gonna try and face it off, if it doesnt cut throught to the hole its good enough
[16:54:09] <mrsunshine_> its just a motor mount for the mill :P
[16:54:20] <mrsunshine_> and 20mm thick alu is a tad bit thick anyways :P
[16:54:40] <mrsunshine_> KimK, problem with remelting is that i have to destroy the casting somehow ...
[16:54:47] <mrsunshine_> saw it in pieces to fit the crucible :P
[16:55:09] <KimK> Ah. Hope it's good enough then.

[17:02:27] <aggrav8d> 16 microsteps
[17:02:55] <KimK> And is Z a 200 steps / rev motor?

[17:12:54] <KimK> So 16 micro steps * 200 motor steps * x1:1 gearing? * 2 tpi = 6400 steps/inch So the motor to shaft gearing is 1:1, is that right?

[17:21:59] <aggrav8d> i loosen the clamps and slide it out.
[17:26:53] <KimK> Do you have a Z travel loop (Z exercise program) written? Just a repeat loop and Z travel of about 80% of maximum (short maybe 10% on each end) will do nicely. I was thinking you should try that, with the router if possible, without if necessary. And try tuning to minimize lost steps. What have you done along those lines so far?
[17:27:27] <lilalinux> toollength compensation is working now, when I use the ngc file. Now I've written a o<lib_toollength> sub, but after g38.2 Z-50 F200 the code stops immediately
[17:27:55] <lilalinux> If I leave out the g38.2 command, the code runs correctly
[17:27:59] <lilalinux> is that a bug?

[17:38:28] <archivist> 1500 rpm for 50hz mains but a motor slips, so the rating is 1425 rpm or similar, I would probably leave as is
[17:39:26] <mrsunshine_> archivist, ye, the motor is 2750 rpm but calculating synchronous its 3000 rpm

[17:58:30] <Guest943> oh
[17:58:36] <Guest943> im using cnc4pc
[17:58:39] <Guest943> bob
[17:59:17] <cradek> I don't know much about that. what kind of motors and drivers?
[17:59:22] <Guest943> i got everything working except i dont understand how to do encoders i got to go out to shop to get my configs (on a different machine)
[17:59:46] <Guest943> anyways my names Tony from jtektool.com
[18:00:52] <KimK> cradek: <whispering>(There's a *new* way to hook up encoders?)</whispering>
[18:01:01] <Guest943> anilam they are critically damped and everything is working using step/dir dirvers
[18:01:01] <KimK> Guest943: Hi Tony
[18:02:02] <skunkworks> Guest943: how many line encoders?
[18:02:38] <cradek> anilam = probably glass scales
[18:02:50] <cradek> .0001 or .0002 resolution showing on his dro
[18:03:39] <KimK> Hi Sam! I guess everybody's dropping by for lunch, lol?
[18:03:54] <bzzzz> cpld stepper drivers shall bring us to the mooooooooon
[18:03:55] <Guest943> yes there are glass scales i want to hook into emc, but there are rotary encoders hooked to otors
[18:04:11] <Guest943> *motors and then hooked into servo drivers
[18:04:27] <anonimasu> Guest943: are you sure it's not tacho's?
[18:04:30] <Guest943> so kind of a dual feedback
[18:04:32] <anonimasu> (just making sure)
[18:04:41] <Guest943> no i put brand new encoders on there
[18:04:56] <KimK> Guest943: Did you look at the wiki on dual encoder feedback? Stuart did that.
[18:05:01] <anonimasu> I see :)
[18:05:51] <KimK> Basically he hooked the glass scales to I, and the encoders to P,D.
[18:05:57] <Guest943> pulled the pin and pressed a new pin in and then used am

[18:06:16] <Guest943> CUI AMT series 100 on the motors
[18:06:26] <Guest943> glass scales to emc?
[18:06:43] <Guest943> the drivers read the rotary encoders
[18:07:52] <Guest943> sorry if I am a retard, but cant be that stupid I installed my gentoo server from stage 1 im just a total newbie to emc
[18:07:56] <KimK> Well, I forgot if Stuart's were actually glass, or if they were one of the magnetic types, but yes, a high-res encoder to EMC.
[18:08:21] <skunkworks> Guest943: what are you hoping to acomplish by hooking the scales into emc?
[18:08:24] <KimK> No problem, this is the palce to ask.

[18:08:46] <Guest943> hold on ill get the model number...
[18:10:42] <Guest943> well maybe some better accuracy, im the resident geek here and my dad
[18:10:48] <Guest943> is the mechanical guy
[18:11:21] <Guest943> we put this machine together but found some backlash in one direction to the tune of .018
[18:11:41] <Guest943> and oddly enough the other is .003 different
[18:11:58] <cradek> .018 is going to make it untunable until you fix the mechanical problem
[18:11:58] <Guest943> which is a whole different problem off subject
[18:12:07] <KimK> Oh, sorry, I just got it. You have those step/direction "servos" using the rotaries for drive feedback, and you want to add glass scales. To do what, close a loop around the steppers(??) Or to just watch for following errors?
[18:12:25] <Guest943> watch following errors and e-stop
[18:12:38] <Guest943> and dro would be nice
[18:12:40] <KimK> Oh, OK, no problem then.
[18:12:55] <cradek> ok, forget my answer then, you aren't wanting to use them for pid.
[18:13:45] <cradek> you will need to get hardware that can count the encoders at the max speed of your machine. if the machine is VERY slow the parallel port and software counting can work, but most likely you'll need special hardware, which you can get from several vendors.
[18:14:19] <Guest943> which hardware
[18:14:21] <Guest943> ?

[18:14:58] <cradek> something that has encoder inputs, mesa and pico systems are the commonly used ones
[18:15:04] <KimK> cradek is right, especially if your scales are high-res, in which case you may have *lots* of pulses to count at high speed.
[18:15:38] <Guest943> ok
[18:15:39] <cradek> unfortunately you've already spent money on a step/dir setup
[18:15:56] <Guest943> right but this is a proof of concept really
[18:16:06] <cradek> velocity or torque mode servo amps (possibly the original ones) would have been a much better match for emc
[18:16:19] <cradek> did you pull out working servo amps?
[18:16:28] <Guest943> yeah but we have piles of them
[18:16:36] <anonimasu> I'd suggest to put them back on
[18:16:36] <cradek> can you put them back in?
[18:16:39] <Guest943> i got 4 machines here
[18:16:44] <anonimasu> and throw thoose step servo thing drives to hell
[18:16:51] <anonimasu> (give them to someone that uses mach)
[18:16:59] <Guest943> of course i could put them back in
[18:17:07] <Guest943> im not sure if they work
[18:17:10] <Guest943> tho
[18:17:12] <anonimasu> you have a amazing setup, to start with if they work
[18:17:47] <aggrav8d> kimk, JT-Shop, i ran the test JT-Shop gave and afterwards there was a 0.1" difference.
[18:18:14] <aggrav8d> i also hear a strange "click" sound when the stepper starts to lower the router.
[18:18:39] <KimK> aggrav8d: And this is still carrying the router? Oh, OK, you've answered my question.
[18:20:02] <Guest943> well thanks for the help so far
[18:20:32] <skunkworks> Guest943: still - get the backlash out of the system..
[18:20:49] <KimK> aggrav8d: If you hear a click, check for loose stuff, especially motor/shaft drive pulleys. And shaft thrust/support bearings.
[18:21:54] <cradek> if a ball nut has .018 backlash, there's something very badly wrong with it
[18:22:11] <cradek> all the balls are busted up, for instance
[18:22:16] <skunkworks> could be thrust bearings also
[18:22:32] <cradek> yes could definitely be bearings, or the nut is not mounted solid
[18:22:35] <KimK> Guest943: You're welcome, sorry if we scared you at first.
[18:22:57] <cradek> or a combination of all of these things add up to .018
[18:23:11] <Guest943> yeah it happens in the *nix world im used to it (and i give it out just the same);)

[18:32:57] <cradek> Guest943: it's just for you to tell your dog/signal apart from all the others
[18:32:57] <skunkworks> should name it to make sense to you
[18:33:01] <cradek> KimK: thank you thank you I'd like to thank my mom, my computer, and my cat sprinkles.
[18:33:20] <KimK> Maybe we should call that the "Kreskin" troubleshooting award?
[18:34:02] <aggrav8d> well i'll check again, i don't see anything loose and the z car doesn't have any play.
[18:34:38] <KimK> aggrav8d: Motor mounting, then?
[18:35:34] <Guest943> so i have senc 125 t/e encoder
[18:36:03] <KimK> aggrav8d: Can you get the click to happen by manual jog in increment mode, say in 0.100" steps?
[18:36:04] <Guest943> my latency is 13000
[18:36:28] <skunkworks> Guest943: what do you have your base period set to?
[18:36:37] <Guest943> 15000
[18:36:47] <Guest943> =approx 44000
[18:36:49] <Guest943> hz
[18:37:06] <skunkworks> really - you don't get any latency errors?
[18:37:28] <skunkworks> 13000 latency and 15000 base leaves no headroom.
[18:37:50] <Guest943> must have something wrong in my brain
[18:39:08] <Guest943> 24645 = base period
[18:39:13] <skunkworks> 44000 hz calculates to about 22000
[18:39:16] <skunkworks> ah
[18:40:40] <Guest943> 14898 max jitter after 24 hours
[18:41:13] <Guest943> of glxgears and all kinds of other crap
[18:41:49] <skunkworks> nice
[18:42:13] <skunkworks> so you can count encoders reliably at 22000hz
[18:43:01] <skunkworks> technically you can push that higher but it depends on how perfect the quadature signal is. I would not try much faster than 22k though
[18:43:01] <KimK> Yes, nice. I've got a latency question for the crowd, but I'll hold it for now since we've got a full plate.
[18:44:19] -!- acemi [acemi!~acemi@unaffiliated/acemi] has joined #emc
[18:45:08] <aggrav8d> kimk - mounting is solid, too. i'm thinking maybe the screw is touching something inside the shaft collar?
[18:45:25] <skunkworks> so - if I have my info right - lets say you have 10000 lines per inch - that is 40000 quadature. 22000hz/40000 is .55 inches per second or 33 inches per minute
[18:45:57] <Guest943> THANK YOU
[18:46:09] <Guest943> 33 ipm is fine for this application actually
[18:46:29] <Guest943> but i dont know lines per inch on this encoder
[18:46:53] <cradek> seems like you'd want to go more like 20 ipm for some safety overhead
[18:47:15] <cradek> (that looks like a hell of a long table for 20 or 33 ipm)

[18:48:01] <skunkworks> cradek: I would think that would be with safety added. Tecnically you should be able to count an edge every base period if the quadature signal is clean.. right?
[18:48:06] <cradek> my bridgeport with 18" of travel did 250ipm. that's probably more like how your machine is supposed to work with the appropriate servo drives.
[18:48:24] <cradek> skunkworks: only if the base periods are clean too (which they aren't)
[18:48:26] <pcw_home> Might be nice for the software encoder to have a quadrature sequence error flag so you will know if you push it too far
[18:48:29] <Guest943> more like 200 originally
[18:48:46] <Guest943> the drive will limit out in firmware
[18:48:46] <cradek> pcw_home: good idea

[18:51:09] <aggrav8d> yes, you folk are a HUGE help and I can't thank you enough.
[18:52:54] <KimK> You're welcome.
[18:54:02] <KimK> I'll slip in my own Q now, maybe? I'm helping a friend on a PC with odd latency issues. We tried a different video card (helped!) and more memory. Got rid of sound. It's intended for a servo-only system, no base thread in final setup. It starts at about 6000ns max, quickly climbs (over 2-4 secs) to about 15,000ns max and stays nicely there.
[18:54:28] <cradek> sounds great
[18:54:28] <KimK> But in about 10-20 minutes it jumps to 24,000,000 ns! The screensaver is off, and there's nothing in cron. Can't be sure about BIOS settings, since I can't see them over the intertube.
[18:54:38] <cradek> oh
[18:54:57] <cradek> doesn't sound so great
[18:56:13] <KimK> And this is an older PC with x2 Pentium 3's and 1GB, if that says anything. But it does well otherwise.
[18:56:33] <skunkworks> is there a keychain drive plugged in by chance?
[18:56:43] <cradek> are all the fans including the cpu fans working?

[18:57:48] <pcw_home> Yeah 10-20 minutes could be thermal
[18:58:28] <cradek> yes P3 systems usually cooperate very well. I'd look for something really out of the ordinary, like overheating.
[18:58:38] <KimK> No flash drive during the test, no. All fans working to my knowledge, but it's a thing to check when I'm actually in front of it. I have tried "running stuff" (glxgears, htop, etc) but lately have fallen back to just idling!
[18:59:27] <KimK> And it's very consistent in the 24,xxx,xxx delay, never anything different.
[18:59:32] <anonimasu> pcw_home: is it absolutely nescessary to have optoisolated stepper drives with the 7i37 ?

[21:03:09] <archivist> is this in relation to braking
[21:03:26] <mrsunshine_> dont know, its in the motor parameters
[21:03:28] <mrsunshine_> on the vfd
[21:03:45] <mrsunshine_> aparently on a vector drive you need both torque current and magnetizing current or something like that
[21:03:45] <archivist> the manual should say why
[21:04:04] <mrsunshine_> archivist, nop :/
[21:04:09] <mrsunshine_> the manual just plain out sucks :(
[21:04:34] <mrsunshine_> no explaination of the parameters, just a bunch of pages with them on and how to install the drive :P
[21:05:50] <mrsunshine_> hmm, tho it also says "motor no load current" ...
[21:06:11] <mrsunshine_> so i guess if i have no load on i should be able to measure it/read it from the vfds display as it displays the current used :P

[21:41:59] <jtektool> i guess i was just wondering if latency issues could be filtered out with use flags (i don't actually have any)
[21:42:15] <jtektool> ie compiling your kernel for your actual processor
[21:43:51] <jtektool> my cnc isnt even networked yet

[22:14:54] <aggrav8d> http://imgur.com/a/dccsv looks like it works!
[22:15:23] <aggrav8d> there was a little play in Z, I tightened the motor housing so that there was no play between the two halves of the shaft coupler.
[22:16:28] <aggrav8d> that cut took 40 minutes at 10ipm through 1/2" MDF with a 1/8" 2 flute at 32000rpm.

[22:21:39] <aggrav8d> Thank you so much for your help, jt & kimk!
[22:23:50] <KimK> Great! Glad you got it going. Now if you want to speed things up until it breaks, be my guest, lol!
[22:26:18] <KimK> I haven't done much with MDF, I heard it's abrasive, probably due to the resins? If you're not already using carbide, you might consider it, even if it is a one-flute straightedge. (Countertop router style).
[22:31:38] <aggrav8d> my next step is to catch up on some overdue projects (This was supposed to be working back in march)
[22:32:14] <aggrav8d> then get some cable chain to clean up my wiring, and a 30' hose for the vacuum (and some kind of skirt around the bit)
[22:32:43] <aggrav8d> after that I plan to buy more bits and a fly cutter to make sure the table is totally flat.
[22:37:48] <KimK> So the play (loose coupler) was the main issue in Z? "Tuning" (pardon me) was at least mostly OK?
