#emc | Logs for 2008-08-12

[00:09:55] <dmess> hi all.. still pouched to boot to HD
[00:14:48] <JymmmEMC> new install?
[00:18:40] <dmess> old... had a power surge or something...
[00:18:56] <JymmmEMC> ah
[00:20:35] <dmess> fried the p/s... but i thought it might be the battery so i replaced it too with out power...
[00:23:50] <pminmo> kind of, it is a computer that has been mainly winxp but had the previous version of ubuntu and emc on it.
[00:24:31] <pminmo> so I did install the 8.04 ubuntu over the old version
[00:24:38] <fenn_> fenn_ is now known as fenn
[00:28:45] <dmess> i HAVENT pounded 8.04 over it YET.. and would rather NOT
[00:30:35] <jepler> euch! eagle gcode.py gave terrible code on this board with rounded traces .. it seems it is clearing lots of tiny, nearly triangular regions between mitered traces and the ground plane
[00:31:16] <toastydeath> I am not happy with 8.04
[00:31:18] <pminmo> jepler blacklisting the saa.... fixed my problem THANKS!!!!!!!!!!!!!!!!!!!!!!!!!!!
[00:31:30] <jepler> pminmo: oh that's good news
[00:31:33] <jepler> it was a total shot in the dark
[00:31:51] <pminmo> well it brought light to my world....
[00:32:18] <pminmo> toasty 8.04?
[00:32:30] <toastydeath> ubuntu
[00:32:45] <pminmo> yes but why are you unhappy
[00:32:50] <pminmo> with it
[00:33:12] <toastydeath> I had xubuntu 6-whatever on my old laptop
[00:33:20] <toastydeath> upgraded
[00:33:28] <toastydeath> and now it craaaaawls
[00:34:04] <toastydeath> the old version had beryl and all sorts of fancy stuff running
[00:34:16] <toastydeath> now I can barely use xfce
[00:34:53] <jepler> toastydeath: by all maens stick with 6.06 for emc2 .. we'll at least do all 2.2.x-series bugfixes for it
[00:35:07] <jepler> 8.04 is fine on my hardware but I tend to spend way too much money on PCs and laptops :(
[00:35:16] <toastydeath> I don't run emc, I was just talking general usage
[00:36:25] <toastydeath> I guess I'll install debian base and go with that
[00:36:47] <toastydeath> I have just not been happy with ubuntu, I guess
[01:02:35] <JymmmEMC> jepler: know anything about opto's?
[01:23:02] <pminmo> optocouplers
[01:25:03] <pminmo> like hpcl 2531 or 6n135 or til19x types or something else
[01:32:33] <jepler> JymmmEMC: only what I read in datasheets
[01:37:55] <pminmo> other than ctr, speed and types there isn't any big stumbling blocks
[01:42:07] <pminmo> of to the store, later
[01:50:38] <dmess> hey all i got my new martin packpacker guitar today.... what an awesome sound fron such a small guitar..
[01:50:42] <dmess> from
[02:00:06] <mozmck> interesting!
[02:00:36] <mozmck> I heard and old small gibson once that sounded unbelievable
[02:18:19] <dmess> how SMALL??
[02:19:08] <dmess> this is 28 inches long and 7 inches tall 2.5 inches deep max
[02:19:13] <JymmmEMC> jepler: thanks =)
[02:19:51] <JymmmEMC> jepler: I was trying to make heads or tails of a few types, but not enough fundamentals for me to make a determination ;)
[02:19:56] <dmess> the backpacker ist conventionally shaped
[02:20:45] <dmess> isn't
[03:36:12] <jmkasunich> wow - the bearings on this surplus spindle cost 276 euros each
[03:40:11] <jmkasunich> http://medias.schaeffler.com/medias/en!hp.ec.br.pr/HC719..-E_FAG*HC71908-E-T-P4S_FAG
[03:40:49] <stustev> jmk - that's scary
[03:41:06] <jmkasunich> those are the back bearings
[03:41:21] <jmkasunich> the front ones are a bit bigger (68mm instead of 62mm OD)
[03:41:29] <jmkasunich> can't read the numbers on those
[03:41:32] <stustev> the back bearing are not angular contact are they?
[03:41:37] <jmkasunich> yep
[03:41:51] <jmkasunich> opposed angular contact at both ends
[03:42:24] <jmkasunich> http://jmkasunich.com/pics/spindle-and-motor.jpg
[03:42:35] <stustev> two on each end?
[03:42:37] <jmkasunich> I have 14 of the spindles
[03:42:40] <jmkasunich> yep
[03:43:06] <stustev> is there a problem with the bearings?
[03:43:23] <jmkasunich> I'm sure at least a few of the spindles have bearing issues
[03:43:31] <jmkasunich> they were surplus, I think sent for repair
[03:43:49] <jmkasunich> most are tagged with things like "bent drawbar", "galled bore", "spline worn"
[03:43:56] <jmkasunich> I don't think any are tagged for bad bearings
[03:44:43] <stustev> you should easily be able to mix and match for a yield of 8 or 10 spindle out of 14
[03:44:54] <jmkasunich> something like that
[03:45:09] <jmkasunich> actually my goal is to redo the nose tapers
[03:45:19] <jmkasunich> they are HSK25 right now, which is $$$ tooling
[03:45:27] <stustev> to another configuration - right?
[03:45:43] <jmkasunich> yes
[03:45:53] <jmkasunich> http://jmkasunich.com/pics/surplus_spindle.pdf
[03:46:03] <jmkasunich> that drawing is my best measurements of the existing taper
[03:46:20] <jmkasunich> the front part is about 0.050 smaller than MT3
[03:46:49] <jmkasunich> I have a drawing around here somewhere showing what needs to be done to make them MT3
[03:47:03] <jmkasunich> then you put a 3/4" collet in there, and use with the Tormach system
[03:47:51] <jmkasunich> I just managed to get all the drawbars out, and some of the additional claptrap removed from all of them
[03:48:05] <jmkasunich> my next step is to make a steady to hold the front end bearings, so I can attempt boring
[03:48:15] <jmkasunich> it will be interesting to see if I can even begin to cut the steel
[03:49:20] <cradek> have any of those ceramic inserts left?
[03:49:37] <jmkasunich> those were diamond - and diamond doesn't work on steel
[03:49:52] <jmkasunich> s/were/are - I only killed the one
[03:50:07] <jmkasunich> it took nice chips off a hardened dowel pin, for a little while
[03:50:27] <jmkasunich> I think CBN is the tooling of choice for hard steel
[03:50:45] <cradek> do you have a way to grind it?
[03:50:47] <stustev> the diamond would work if you could machine some non carbon steel
[03:51:00] <jmkasunich> cradek: I might
[03:51:29] <cradek> the problem with MT is it's so very long
[03:51:31] <jmkasunich> the bosch gadget does 48000 RPM, if I can figure out how to put a small-diameter grinding wheel in there
[03:51:32] <stustev> cbn is the material for steel
[03:52:27] <jmkasunich> the tormach tooling only extends up in the collet by 1-3/8", and the collet only bears on the inside of the taper for the first 1-3/4"
[03:52:36] <jmkasunich> the rest is relieved, and only need to have clearance
[03:52:44] <jmkasunich> so I need 1-3/4" of good taper
[03:53:01] <stustev> truncate the taper - you beat me to it
[03:53:59] <jmkasunich> overall depth is still 3-1/8", so even if I don't need accurate, getting in there will be "fun"
[03:54:05] <stustev> with my grinder and cbn wheels - if the wheel is sparking it is not wearing at all - if it is not sparking it is cutting very little
[03:54:46] <jmkasunich> is that your spindle regrinding setup?
[03:55:18] <stustev> yes
[03:55:59] <jmkasunich> mcmaster has CBN mounted points ;-)
[03:55:59] <stustev> if it is not sparking it is cutting very little and wearing a lot
[03:56:43] <stustev> will your grinder handle the load?
[03:57:36] <jmkasunich> its a 400W AC motor (used with a VFD that can go to 300Hz) - definitely better than Dremel class
[03:57:50] <stustev> it will take a llllloooonnnnnggggg time to grind the different shape if you don't rough it with something
[03:58:16] <cradek> yay cnc
[03:58:24] <stustev> yay
[03:58:34] <jmkasunich> yeah, when I said "CBN" I was thinking of boring inserts, not grinding wheels
[03:58:39] <jmkasunich> grind for finish only
[03:58:46] <stustev> if it will to 48,000 rpm the bearing must be pretty good
[03:59:02] <stustev> go to
[03:59:09] <jmkasunich> the bosch spindles? they are small
[03:59:51] <jmkasunich> don't have a pic handy
[04:00:07] <jmkasunich> the main complication with those is that I have _one_ collet, and it is for a 6mm shank
[04:00:16] <stustev> maybe you could have someone (with a cnc lathe and experience cutting taper adapters) make a few for you? :)
[04:00:50] <jmkasunich> a few what?
[04:00:59] <stustev> hsk adapters
[04:01:22] <jmkasunich> oh - I don't think so
[04:01:24] <cradek> hsk->tormach?
[04:01:28] <jmkasunich> HSK is just too exotic
[04:01:42] <jmkasunich> no, they'd have to be HSK toolholders I think
[04:02:28] <jmkasunich> I'm actually looking forward to the challenge of reboring the spindles
[04:02:47] <stustev> I understand that concept
[04:03:11] <jmkasunich> hopefully I will succeed before I have ruined all 14 of them
[04:03:20] <cradek> speaking of that, how is the cinci?
[04:03:45] <jmkasunich> if I get one good one, it goes in my gantry mill.... two, and I have a spare... three or more - Profit!
[04:03:55] <toastydeath> lol hsk has 20 millionth tolerances in the spec
[04:04:05] <jmkasunich> yeah, HSK is just insane
[04:04:05] <stustev> I saw maintenance assembling the hydraulic lines this afternoon. Just about ready to put the spindle in.
[04:05:09] <cradek> cool. what is left after that?
[04:06:22] <stustev> I have the lead screw comp information - I need to tune the axes a little more - soften the drives a little - test cut a part and hopefully that's it
[04:07:09] <cradek> what a long strange trip it's been
[04:07:51] <stustev> oh my - this last detour was my fault entirely - this has been the most aggravating delay I have had
[04:08:32] <stustev> but we are almost back :)
[04:09:08] <stustev> we learned a lot - how to disassemble and reassemble the spindle and gearbox
[04:09:17] <stustev> completely
[04:09:21] <cradek> heh
[04:09:33] <cradek> the bright side!
[04:09:34] <stustev> education is expensive
[04:10:33] <stustev> we will now be able to diagnose problems with a high degree of certainty
[04:11:12] <stustev> A GOOD POINT - we will be able to 5 axis rigid tap
[04:11:27] <stustev> we didn't have the feedback before - now we do
[04:11:36] <cradek> that will be very slick.
[04:12:14] <stustev> very cool if we ever have the need - I will look for opportunities
[04:12:17] <cradek> for that feature you will need to add 20% to the cost of the control software
[04:12:30] <stustev> ha ha ha neat
[04:12:38] <stustev> I would pay double
[04:13:08] <cradek> that's a customer testimonial you don't see on many advertisements
[04:13:22] <stustev> that's a fact
[04:13:26] <toast> lol
[04:14:02] <cradek> I had lots of success with the lathe today. I have tool change under gcode control, and lots of other things.
[04:14:02] <jmkasunich> my "maybe" spindle ID grinder: http://jmkasunich.com/pics/bosch-48k-spindle-2559.jpg
[04:14:12] <toast> cradek: what kind of lathe?
[04:14:35] <cradek> hardinge HNC retrofit I'm doing
[04:14:40] <toast> oh yeah
[04:14:41] <toast> a+
[04:15:20] <stustev> that looks adequate - it should do the trick
[04:15:41] <toast> what spindle are you grinding?
[04:15:54] <jmkasunich> I either have to make a new collet for 1/8" shank stones, or somehow reduce the 1/4" shank ones to 6mm (0.236)
[04:15:59] <toast> oh
[04:16:03] <toast> cool beans man
[04:16:19] <jmkasunich> toast: I want to change the taper in this: http://jmkasunich.com/pics/spindle-and-motor.jpg
[04:16:48] <cradek> I don't understand how the collet works. is there a drawbar?
[04:17:08] <toast> yeah what kind of collet is that
[04:17:13] <jmkasunich> no, you turn the hex on the outside, the threads on the inside draw it into the spindle
[04:17:39] <cradek> oh, weird
[04:17:40] <toast> so is it like, 5c or something
[04:17:44] <jmkasunich> the slits don't show in the photo, they start about half way thru the cylindrical shiny band, and extend forward all they way thru the nut
[04:17:56] <cradek> yeah I see one
[04:17:58] <jmkasunich> sort of like 5C, but instead of drawing it in from the back , you screw it in from the front
[04:18:10] <cradek> very strange to crank on the flexy part to tighten it.
[04:18:13] <jmkasunich> yeah
[04:18:25] <jmkasunich> I imaging there will be a bit of runout from that
[04:18:30] <toast> i mean do you know the actual taper designation
[04:18:42] <jmkasunich> toast: no clue
[04:18:48] <toast> oh
[04:19:13] <jmkasunich> I have no idea what this is from - it had a 6mm shank solid carbide burr in it
[04:19:16] <cradek> doesn't seem hard to make a new collet. if there is runout, the grinding wheel will "adjust" shortly
[04:19:44] <jmkasunich> I wish I could do 1/4" shank - would be much better than 1/8
[04:19:48] <stustev> toast: you are looking at the spindle grinding collet not the spindle taper he is wanting to change
[04:19:59] <toast> oh.
[04:20:00] <jmkasunich> yeah, there are two spindles we're talking about
[04:20:18] <jmkasunich> small fast one (48K RPM) that I want to use for ID grinding the taper on the larger one
[04:20:27] <toast> what's the large one?
[04:20:43] <jmkasunich> the large ones are HSK25
[04:20:54] <toast> hahaha how'd you wind up with an hsk spindle
[04:20:59] <jmkasunich> surplus
[04:21:06] <jmkasunich> I wound up with 14 of them to be precise
[04:21:11] <jmkasunich> at $10 each ;-)
[04:21:11] <toast> hahahahahaha
[04:21:23] <toast> and now you need to tool them at 350 per holder, amirite
[04:21:29] <toast> =)
[04:21:56] <jmkasunich> no, I need to bore and grind the taper to MT3, then use an MT3 - 3/4" collet and Tormach Tooling System
[04:22:01] <stustev> now he wants to retaper them so the tooling is much less expensive
[04:22:02] <toast> a+
[04:22:22] <toast> does the ID clamping stuff get in the way of doing that?
[04:22:34] <toast> or does that whole assembly come out of the spindle pretty easy
[04:22:35] <jmkasunich> drawbar and such? that is all removeable
[04:22:38] <toast> hot
[04:22:43] <jmkasunich> got the drawbars out yesterday
[04:23:10] <jmkasunich> here is a drawing of the spindle/drawbar/etc: http://jmkasunich.com/pics/surplus_spindle.pdf
[04:23:29] <stustev> the belleville washer stack looks as if it is almost the full length of the spindle. Wiil you be able to use the drawbar and bellvilles with the new system
[04:24:08] <jmkasunich> not sure - after I've made some progress, I'll call tormach and see if they know what drawbar tension is recommended
[04:24:26] <toast> MT doesn't like compression drawbars
[04:24:33] <jmkasunich> I haven't measured the spring force yet (duh, I should have done that before I pulled all the drawbars out, gotta put one back together)
[04:24:45] <jmkasunich> toast: yeah, I was thinking that might be the case
[04:24:57] <toast_> exciting
[04:25:15] <jmkasunich> that skinny part in the front is 6mm - I could make the back part out of say 3/8", and tap the front M6
[04:25:20] <stustev> you can adjust the retention force by adjusting the length of the drawbar
[04:25:29] <jmkasunich> then make a short piece of 6mm drillrod with M6 threads on both ends
[04:26:10] <toast> wtf
[04:26:17] <toast> anyway.
[04:26:25] <toast> mt tapers don't have pullstuds
[04:26:33] <toast> so they can't use "cnc style" drawbars
[04:26:48] <jmkasunich> in the tormach system, the collet stays in the spindle all the time
[04:27:04] <toast> so no problem then1
[04:27:05] <toast> !
[04:27:10] <jmkasunich> tools have a 3/4" straight shank and a shoulder that goes against the spindle nose
[04:27:23] <jmkasunich> stick it in, and when the collet tightens it pulls the shoulder tight
[04:27:33] <jmkasunich> good rigidity, and very repeatable Z
[04:27:36] <toast> oh, that'll work great with a drawbar then
[04:27:48] <jmkasunich> a real drawbar, or a spring one?
[04:27:53] <toast> a spring one
[04:28:05] <jmkasunich> I have to put one back together and measure the spring force
[04:28:16] <jmkasunich> I can compress it without too much trouble using the drill press
[04:29:00] <toast> you can always change the springs if required?
[04:29:05] <stustev> just collapse a few bellevilles - the force for the whole stack is no more than you get with one washer - the stack just gives you more collapse motion
[04:29:26] <toast> yar
[04:29:34] <jmkasunich> stustev: true, didn't think of that
[04:30:02] <jmkasunich> although I don't know how I'd measure the force of one or two washers
[04:30:13] <jmkasunich> I think I'll just put the bathroom scale on the drill press table ;-)
[04:30:17] <toast> lol
[04:30:31] <stustev> how would you measure the force of the stack inside the spindle?
[04:30:42] <jmkasunich> the drawbar sticks out the back a bit
[04:30:48] <toast> i guess you could use an indicator and a fish scale
[04:30:55] <jmkasunich> set the nose on the scale, push the back with the end if the drill chuck
[04:31:13] <stustev> A BIG fish scale - several hundred pounds
[04:31:52] <jmkasunich> there are two different kinds of spring stacks
[04:31:55] <toast> i was just referring to the type of scale, not actually suggesting a scale for fish =)
[04:32:04] <jmkasunich> 6 of the spindles have bellvilles as in the drawing
[04:32:08] <stustev> the cinci has 5600 lbs of retention pull - the fadals 1000 lbs - the Haas machines are around 1200 lbs (I think)
[04:32:31] <jmkasunich> the other 8 have some weird kind of spiral bellville thing
[04:32:49] <jmkasunich> stustev: I don't think these are that high
[04:32:58] <toast> what taper's the cinci, 50?
[04:33:09] <stustev> yes - 50 taper
[04:33:11] <toast> HSK is probably in the 1000 lbs range
[04:33:31] <K`zan> Evening folks. Anyone here with a 7x12 mini-lathe?
[04:33:33] <toast> the harder you push it the harder it clamps
[04:33:42] <jmkasunich> I bet these are under 500
[04:33:45] <toast> snap.
[04:33:52] <jmkasunich> (HSK25 is about the smallest of the HSK tapers)
[04:33:53] <stustev> I wouldn't even want to guess what tormach recommends
[04:34:13] <toast> lol it can't be 1000 lbs
[04:34:26] <cradek> for MT, 500lb would stick it just about forever wouldn't it?
[04:34:28] <jmkasunich> I'll ask them, once I've determined that can actually scratch the surface inside the bore
[04:34:41] <K`zan> Sigh, OK, thanks anyhoo :).
[04:34:50] <stustev> collets have a max clamping pressure - more than the max just starts to distort things
[04:35:03] <cradek> K`zan: is your actual question specific to that lathe?
[04:35:07] <jmkasunich> cradek: you'd be surprised how much force you can get from a 3/8-16 solid drawbar
[04:35:11] <toast> cradek: which MT
[04:35:11] <toast> mt3 probably
[04:35:16] <jmkasunich> yeah, MT3
[04:35:40] <toast> plus a quick knock on the backend of the drawbar
[04:35:42] <toast> and POP
[04:35:46] <toast> out comes the collet
[04:36:45] <jmkasunich> yep
[04:37:09] <jmkasunich> so, if I need to use a solid drawbar, that can be done - if I can use the springs, that's even easier
[04:37:25] <toast> i think you have a good setup if you want to use MT3 + tormach
[04:37:28] <jmkasunich> but first I gotta see if I have a snowball's chance in the hot place of even cutting the bore
[04:37:32] <toast> because MT3 power drawbars need to rotate
[04:37:52] <toast> so once you get the mt3 in there by hand, the kickout will only affect the tormach tool
[04:38:04] <stustev> the springs will give you a longer life of the collet and more reliable, repeatable clamping
[04:38:26] <toast> tru
[04:38:41] <jmkasunich> and will let me reuse the existing bar (maybe)
[04:38:47] <toast> hopefully.
[04:39:03] <jmkasunich> the skinny (6mm) part in the front will need to be shortened
[04:39:17] <jmkasunich> I don't have high hopes of being able to thread it after I cut it off
[04:39:22] <jmkasunich> thread-grinding anyone
[04:39:34] <toast> lol
[04:39:46] <toast> my shop used to have those
[04:39:53] <toast> not anymore though
[04:39:59] <stustev> I believe you will be able to cut the spindles. Mill the threads with a carbide cutter.
[04:40:15] <toast> yar, i doubt the drawbar is any more than like rc-36
[04:40:39] <stustev> I have EDM. If all else fails we will get the tapers like you want.
[04:40:45] <toast> hahahaha
[04:40:59] <jmkasunich> yay, just tested the drawbar, a file will cut it
[04:41:13] <jmkasunich> same test on the spindle bore, and it laughs at the file
[04:41:29] <stustev> case hardened
[04:42:09] <jmkasunich> means I'll probably be into the core by the time I do the final taper
[04:42:20] <stustev> LOL
[04:42:21] <jmkasunich> should be fine for home shop duty tho
[04:43:13] <stustev> why should home shop duty require anything less than production duty?
[04:43:39] <toastydeath> lol
[04:43:43] <jmkasunich> less wear resistance is acceptable when the duty cycle is 1 hour a day, a few days a week, vs 8/5 or more
[04:43:54] <jmkasunich> less accuracy is not acceptable
[04:44:12] <stustev> yes
[04:45:33] <stustev> goodnight gentlemen - I need my beauty sleep
[04:45:37] <toast> night
[04:45:45] <jmkasunich> gack.... CBN boring insert, .165 IC, $115
[04:46:03] <jmkasunich> I should sleep too - thanks for all your ideas, I _will_ be asking again
[04:46:17] <toast> lol
[04:46:29] <toast> don't crash that insert
[04:47:20] <jmkasunich> have to try plain carbide (or even ceramic) first
[04:47:40] <toast> ceramic will cut it
[04:47:52] <toast> might not last very long but it'll cut
[04:48:13] <toast> we actually cut case-hard stuff at work with brazed carbide
[04:48:21] <toast> as long as you keep touching the cutter up
[04:48:24] <toast> it will work pretty good
[04:48:45] <jmkasunich> * jmkasunich gotta get working on the steady, so I can chuck one up and see what happens
[04:50:28] <toastydeath> lol
[04:52:20] <toast> lol
[04:52:44] <jmkasunich> steady will support the front bearings, so my crappy lathe spindle won't be the limiting factor
[04:52:47] <toast> apparently i have to sit a certain way or my laptop disconnects
[04:52:52] <jmkasunich> steady goes on here: http://jmkasunich.com/pics/steady-base-on-ways-1837.jpg
[04:52:54] <toast> yar that is a good idea
[04:53:24] <jmkasunich> I'm hoping that will make a nice rigid setup
[04:55:30] <jmkasunich> time to walk the dog - goodnight

[08:19:37] <micges> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2008-08-12.txt
[08:38:44] <micges> cradek: Problem that I reported was fixed in 2.2.6 (not switching to G61 after abort)
[08:40:19] <micges> one thing is still not clear to me: what state of interpreter (modes, planes, switches) it has after emergency abort of program (F1) or external signal ?
[12:35:35] <jepler> micges: only running to the end of a program that ends with M2 and M30 defines elements of the interpreter state after the program ends (http://linuxcnc.org/docs/html/gcode_main.html#M2--1). If you interrupt the program's execution in other ways such as with estop, the state is not defined. That is why I recommend always including modal settings at the top of the program (http://linuxcnc.org/docs/html/gcode_main.html#r8_4)
[12:42:45] <micges> thanks jepler
[16:19:34] <jepler> I wonder whether to skip the RC filter on these switches and instead rely on emc's debounce component -- so far that has been working for me
[16:20:02] <jepler> the internet sure has a lot of opinions about the usefulness and reliability of RC filters as a way to do switch debounce
[16:20:31] <archivist_ub> heh, Ive had fun with software debounce
[16:21:06] <archivist_ub> make an RC too slow and that gives as many problems
[16:21:07] <jepler> jmk wrote emc's software debounce so the odds are that it's as good as it gets :-P
[16:21:26] <cradek> jepler: if you have enough inputs to wire the NC and NO, you could use both
[16:22:05] <jepler> (every once in awhile I just have to step back and marvel at how reliable rtapi, hal, and all the components jmk wrote are)
[16:22:06] <cradek> I think that gives you edge detection (perfect debounce) but what you really want is noise elimination
[16:22:29] <LawrenceG> rc really help when there is a chance someone may operate a handheld radio near the control.... I have seen some very big machines do some strange stuff when the electrician calls his buddy for coffee!
[16:22:39] <jepler> LawrenceG: hah
[16:22:53] <alex_joni> ouch :)
[16:22:58] <jepler> I have an intermittent noise problem but it doesn't seem correlated to running the spindle .. I didn't try using my cellphone, however
[16:23:06] <archivist_ub> and a welder being run nearby
[16:23:38] <archivist_ub> screen stuff if no filter used
[16:26:11] <alex_joni> you need to look out for metal ants sneezing around the machine
[16:28:38] <skunkworks> they are carbon fiber ants.. not metal..
[16:29:01] <alex_joni> those don't create a lot of static charge when sneezing
[17:34:00] <toastydeath> fffff
[18:19:29] <tom1> re defaults at begin of program... use G20 / G21 as you need ( a definite inch bias in the docs )
[18:21:01] <tom1> re debounce: M$'s solution "are you sure?"
[19:05:42] <garfield> garfield is now known as gefink
[19:30:51] <robin_> time for more servo tuning fun!
[19:31:06] <skunkworks> yeah
[19:33:46] <archivist_ub> just been reading jmk's blog on the giddings servo tune "We got to hear what it sounds like when a multi-ton table starts to oscillate at 5-10 cycles per second, pushed by a 45 amp servo drive."
[19:34:03] <archivist_ub> I want to play!
[19:35:37] <robin_> heh
[19:35:46] <robin_> mine is decidely not that big
[19:35:51] <robin_> but seemingly a PITA to tune
[19:36:19] <robin_> having only 500PPR encoders is not helping .. it sounds as rough as fsck with even a little bit of D term
[20:03:19] <robin_sz> P + a little FF1 seems ok,
[20:50:37] <Guest978> Howdy all,
[20:51:40] <Guest978> I am able to get tkemc to work, but when i try mini, it won't come off of estop. Any idea?
[20:53:07] <jepler> mini behaves differently than the other guis when it comes to estop handling at the keyboard. I'm not too familiar with it, so take what I'm about to say with a grain of salt
[20:53:42] <jepler> when the button says 'estop push' that's actually the "machine on" mode. The label should be interpreted as: this button can now be pushed (clicked) to activate estop
[20:53:57] <jepler> when you've actually entered the estop state it says "estopped"
[20:54:28] <jepler> there'a third state "estop reset"
[20:54:42] <jepler> If the button says "estopped", press F1 to leave estop and go into machine on mode
[20:54:50] <jepler> if it says "estop reset", press F1 to go into machine on mode
[20:55:02] <jepler> If it says "estop push", press F1 to go to "estopped" or F2 to go to "estop reset"
[20:55:15] <jepler> clicking the button is always like pressing F1
[20:55:31] <jepler> this is how it behaves for me when running the sim/mini sample configuration file
[20:56:03] <jepler> mini was written for sherline mills which don't have an external estop, or at least not one that goes into the PC, and it works a bit differently from tkemc or axis (axis is what I'm most familiar with)
[20:56:29] <jepler> and here's what the docs have to say about it: http://linuxcnc.org/docs/html/gui_mini.html#r1_4_6
[20:57:13] <jepler> Guest978: I hope that helps you understand what mini is doing and how to use it
[20:58:23] <jepler> bbl
[21:03:28] <Guest865> hello, jepler?
[21:03:33] <Guest865> i got dissconnected

[21:03:44] <Guest865> my connection must have some issues
[21:03:47] <alex_joni> Guest865: read that :)
[21:03:56] <alex_joni> jepler wrote a lot of things .. :)
[21:04:13] <Guest865> shoot
[21:04:33] <alex_joni> Guest865: but basicly the idea is that mini has some other e-stop concepts as tkemc
[21:04:44] <alex_joni> iirc it comes on enabled by default
[21:04:59] <alex_joni> read the log at : http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2008-08-12.txt
[21:05:08] <Guest865> ok

[21:55:51] <skunkworks> stupid quetion.. .run files on ubuntu.. how does that work?
[21:56:30] <skunkworks> I am trying to install 5.1.0 eagle on ubuntu and it isn't in the package manager.. So I downloaded it from eagles site
[23:28:01] <skunkworks> found it. have not tried it.. http://ubuntuforums.org/showthread.php?t=239797&highlight=.run
