[00:02:15] <JT-Shop> andypugh: I think it was a hardware issue, but not sure if it was pebkac or not
[00:03:37] -!- theorbtwo [theorbtwo!~theorb@91.84.53.6] has joined #emc
[00:05:11] <andypugh> I have given up being clever with radius compensation, I am going to just re-do the touch-off
[00:05:30] <JT-Shop> what are you trying to do?
[00:05:43] <andypugh> Turn a sphere
[00:06:18] <andypugh> But my tools are normally touched-off with no compensation.
[00:06:38] <JT-Shop> is it not playing along nice or did you forget to lie on the floor and look up when you visualize
[00:06:38] <andypugh> So, to the two tangents, not the tool centre of curvature
[00:06:43] <JT-Shop> so are mine
[00:07:24] <andypugh> Well, that means that the controlled point is outside the radius, not inside, doesn't it?
[00:07:48] <JT-Shop> it is on the edge of the radius
[00:08:48] <andypugh> Yes, so that means that you need to touch-off with compensation on?
[00:09:35] <JT-Shop> no, the tool table diameter takes care of that... I think... :/
[00:09:59] -!- roberth_ has quit [Ping timeout: 240 seconds]
[00:10:37] <andypugh> Only if you have compensation on...
[00:10:59] <JT-Shop> I've never touched off with G41/42 on
[00:11:35] <andypugh> And you get the same dimensions with and without G41?
[00:11:58] <JT-Shop> well without I have to program a different path to get the same part
[00:12:20] <andypugh> Huh?
[00:12:51] <JT-Shop> http://www.linuxcnc.org/docview/html/lathe_lathe-user.html#r1_7
[00:13:29] <JT-Shop> brb
[00:17:04] <andypugh> Hmm, That is failing to explain to me. Partly because all the pictures are "here it is going wrong" with no "here it is going right"
[00:18:27] <JT-Shop> hmmm

[00:20:22] -!- Loetmichel has quit [Ping timeout: 276 seconds]
[00:22:38] <andypugh> So, basically, in Lathe mode, EMC2 already takes account of the fact that the controlled point is outside the tool? But that doesn't really fit with the phrase "When using cutter comp on a lathe think of the tool tip radius as the radius of a round cutter"
[00:23:16] -!- Loetmichel [Loetmichel!Cylly@p54B1433F.dip.t-dialin.net] has joined #emc
[00:26:03] <andypugh> If I play Chris' trick of using /G41 I think that I had actually been misunderstanding it.
[00:28:20] <JT-Shop> yea, after reading that a few times it doesn't make sense... I think it should be the control point follows the radius of the tool to a point parallel to the X and Z axis
[00:28:32] <JT-Shop> when using cutter compensation
[00:30:02] <andypugh> Or, the position of the control point is modified such that the tool cuts the required path. It does seem like with a lathe you can get the same parts with and without cutter comp, as long as all your cuts are perpendicular.
[00:30:03] * skunkKandT really needs to start using cutter comp
[00:30:35] <JT-Shop> yes, straight turning or facing you don't need cutter comp
[00:31:41] <JT-Shop> some of my ngcgui subroutines use comp for chamfers and stuff like that
[00:31:51] <andypugh> But the interesting point is that it seems you can have it on or off and get the same result, so as long as you touch-off to perpendicular faces, cutter comp is a lot less intrusive on a lathe than a mill.
[00:31:53] <Danimal_garage> i dont use cutter comp
[00:32:43] <JT-Shop> the same result for straight perpendicular to an axis cuts yes
[00:35:14] -!- bootnecklad has quit [Ping timeout: 252 seconds]
[00:37:20] <skunkKandT> Danimal_garage: I really should use it for part size adjusting. Now it is - edit gcode or adjust cad and re-output.
[00:38:04] <JT-Shop> take a thou off of the diameter of the tool to make the part a bit smaller :)
[00:38:13] <skunkKandT> exactly.
[00:38:29] <skunkKandT> I am mainly just lazy
[00:38:35] <JT-Shop> lol

[00:41:31] <Danimal_garage> i dont seem to have that problwem. i just change the tool when it gets worn
[00:41:33] <JT-Shop> your supposed to say you work smarter not harder
[00:42:07] <andypugh> I wonder if my witty pun just now (on a different forum) offended someone. He was talking about knots per hour per hour, and I told him not to be a jerk.
[00:42:28] <JT-Shop> lol
[00:42:43] <JT-Shop> acceleration heh
[00:43:22] <andypugh> No, that was rather the context. a "knot" is a velocity
[00:43:33] <andypugh> Well, actually, a speed.
[00:43:40] * JT-Shop hands andypugh a cold one and a huge piece of fresh made beef jerky
[00:43:55] <Gromits> is ssi still about?
[00:44:16] * andypugh wanders off to find a carnivore to give the jerky to.
[00:44:18] <JT-Shop> dunno, can't see him from my house
[00:44:23] <JT-Shop> lol
[00:44:43] <JT-Shop> are you a herbivore?
[00:45:35] * JT-Shop wanders over to the mill to drill and tap a few holes
[00:47:07] <Danimal_garage> i bet he drinks wine coolers too
[00:47:19] <Danimal_garage> or smirnof ice
[00:47:30] <Danimal_garage> :)
[00:47:48] <andypugh> No, tepid beer and red wine
[00:47:59] <andypugh> Not together
[00:48:02] * skunkKandT remember he has everything to make brandy old fashions at home
[00:48:09] <skunkKandT> (it is a WI thing)
[00:48:49] <andypugh> I suspect that Danimal is really making an illicit still.
[00:49:16] <Danimal_garage> an old fashioned is commonly refered to as something else around here
[00:49:40] <Danimal_garage> one may recieve an old fashioned behind the wood shed from his creepy uncle carl
[00:49:48] <skunkKandT> eww
[00:50:06] <skunkKandT> not what I was referring to..
[00:50:10] <Danimal_garage> andypugh: i'm more of a beer guy, however i havent been drinking lately
[00:50:57] <andypugh> Nor me, it's been days.
[00:51:40] <Danimal_garage> a month for me
[00:52:05] <Danimal_garage> longest i've gone since 9th grade
[00:52:11] <Danimal_garage> :)
[00:52:43] <andypugh> Gosh darn it! I am getting a gouging warning!
[00:53:00] <andypugh> On a _sphere_
[00:53:22] <skunkKandT> is the sphere made of short line segments?
[00:53:52] <andypugh> No, I am doing one side of it, with a G3
[00:54:11] <skunkKandT> hmm - then it shoud work ;)
[00:54:16] <skunkKandT> should even
[00:54:25] <andypugh> That is also my opinion.
[00:59:26] <JT-Shop> red is good
[01:01:11] <JT-Shop> pastebin the g-code
[01:03:48] <andypugh> I think I can see the problem.
[01:04:02] <andypugh> http://pastebin.com/du0GaYKv
[01:04:48] <andypugh> I guess the interpreter has no way to know that there is no material left
[01:05:16] -!- elmo40 has quit [Read error: Connection reset by peer]
[01:07:23] <andypugh> Going to be a pain in the wossname to sort it out though, as I need to arc to a point on an arc, but that is a calculated point, not an absolute point.
[01:08:05] <andypugh> (The code is to turn a sphere in a stalk, first leaving a stalk, then set stalk to zero, turn the work round in the chuck, and machine the other hemisphere.
[01:08:39] <andypugh> Because the stalk diameter is a parameter, blending to avoid gouging is difficult.
[01:10:26] <andypugh> Seems OK with a 0.8 radius, though, so I might get away with it.
[01:12:31] <andypugh> Anyway, time to log.

[02:02:39] <FinboySlick> I've been pondering optimizing acceleration for my mill. Making it run a circle of ~accel_distance radius as fast as it will go for a little while and then return to an initial position would let me know if it skipped steps... Or is there a better way?
[02:09:02] <Jymmmm> JT-Shop: I can. as long as it's not PVC (anodized aluminum, acrylic, glass, etc)

[03:00:35] <Gromits> Are you still there ssi?
[03:00:54] <Gromits> I saw earlier you said you have a LCTHC on a machine?
[03:02:56] <Gromits> We are in the process of getting a config for this model working in EMC. I got config files from James Cizek who got it mostly working.
[03:04:14] <Gromits> Our machine has servos/encoders running off of step/dir from a Mesa card so we are having to change things a bit to accommodate the PID and other differences, but we are making progress.
[03:05:43] <Gromits> If you decide to try the LCTHC with EMC send email to the users list (or find me here) and I can forward James' files as well as mine (when we get them done). I hope to find time to post stuff to the wiki at some point once things are working
[03:12:39] <ssi> yeah I'm here
[03:12:56] <ssi> cool I'll definitely check it out
[03:13:11] <ssi> converting the table isn't a high priority right now... it runs ok as is, and I have the lathe and the mill to work on
[03:13:34] <ssi> my table is running all 200oz/in steppers on a G540
[03:13:45] <ssi> I think they're 205's
[03:14:05] <Jymmmm> ssi: how do you like it?
[03:14:17] <ssi> what, the table?
[03:14:19] <ssi> it does pretty well
[03:14:21] <Jymmmm> G540
[03:14:41] <ssi> G540 is good... probably not the way I'll go in the future now that I know about mesa stuff

[03:15:21] <ssi> plasma table is a homebuild
[03:15:26] <Jymmmm> What machine is the g540 on?
[03:15:31] <ssi> the plasma table
[03:15:46] <ssi> I have a spare G540, you looking for one?
[03:15:51] <Jymmmm> gotcha
[03:17:50] <ssi> the big upside to the G540 is it makes wiring very simple
[03:18:29] <Jymmmm> Yeah, I wish it existed when I bought my Xylotex board
[03:18:42] <ssi> first thing I bought was a hobbycnc kit
[03:18:50] <ssi> that's where those 205oz motors came from
[03:18:56] <Jymmmm> I have a PERFECT enclosure for it =)
[03:19:02] <ssi> heheh
[03:19:07] <ssi> I wasn't crazy about it
[03:19:13] <ssi> a channel burned out right off the bat
[03:19:17] <ssi> like smoked the traces on the board
[03:19:23] <ssi> and I had lots of weird issues with it
[03:19:32] <ssi> so I broke down and bought the gecko...
[03:19:44] <Jymmmm> ouch, I think one did on the xylotex too, but had it replaced/fixed under warranty.
[03:20:36] <ssi> actually, before I built the plasma table, I built this little guy
[03:20:36] <ssi> http://www.youtube.com/watch?v=GEAsDafIYUI
[03:20:41] <ssi> that's what I bought the hobbycnc for
[03:21:25] <Jymmmm> was that a kit?
[03:21:29] <Jymmmm> the gantry router
[03:21:31] <ssi> nope
[03:21:52] <ssi> designed it from scratch in solidworks, machined it all out of barstock on my knee mill
[03:21:54] <Jymmmm> eeeesh,, lots of milling =)
[03:21:54] <Gromits> that's a quick little bugger ;-)
[03:21:59] <ssi> it was a pretty ambitious first project :P
[03:22:10] <Jymmmm> =)
[03:22:15] <Jymmmm> what rails does it use?
[03:22:20] <ssi> thompson shaft
[03:22:36] <Jymmmm> round?
[03:22:40] <ssi> the gantry has rail supports milled into it and profiled with a ball mill
[03:22:44] <ssi> and the shaft is drilled and tapped
[03:22:52] <Jymmmm> ah
[03:23:02] <Gromits> i want to build one with linear motors.
[03:23:18] <ssi> I never really got that machine running
[03:23:21] <ssi> problem is the Y axis
[03:23:23] <ssi> I need to redesign it
[03:23:24] <Jymmmm> What, so you can go 200 MPH =)
[03:23:39] <ssi> it has a pair of 1/2" unsupported shafts
[03:23:39] <Gromits> exactly!
[03:23:50] <Jymmmm> ah
[03:23:56] <ssi> and a 2" wide carriage that rides on four thompson ball bearings
[03:24:00] <ssi> and it's just not precise enough
[03:24:04] <ssi> the whole gantry rocks
[03:24:05] <Tom_L> how's torque on those compared to steppers?
[03:24:19] <ssi> so my plan is to make the gantry fixed in like a 24" deep base
[03:24:22] <ssi> and make just the table move
[03:24:24] Tom_L is now known as Tom_itx
[03:24:31] <ssi> bearings can be spaced out by the depth of the table, which is 12"
[03:24:38] <ssi> so it should be much more stable, and it'll be bearing less weight
[03:24:45] <ssi> I basically want that machine to just do engraving work
[03:25:17] <Jymmmm> ssi: Not rigis enough for engraving, you need 4" thick plate all around

[03:27:47] <ssi> uses a 180W RC brushless motor
[03:28:10] <ssi> ER16 chuck
[03:28:16] <Tom_itx> 12v?
[03:28:32] <ssi> I think I can do up to 14.8V on that controller?
[03:28:48] <ssi> I dunno, I never really finished it ;)
[03:28:56] <ssi> I'd need some little logic board to run the speed controller from emc

[12:33:58] <anonimasu> can you control a Q parameter value through pyvcp?
[12:34:05] <anonimasu> I want to control preheat time
[12:37:08] -!- IchGucksLive has quit [Quit: ChatZilla 0.9.87 [Firefox 8.0/20111115192257]]
[12:37:41] <jthornton> might do that in classicladder
[12:38:34] <anonimasu> how heavy is that to implement?
[12:38:51] <anonimasu> (ie how heavy is it to get cl running?
[12:39:07] <jthornton> add a line or two to your hal file
[12:39:36] <anonimasu> can you make a M code wait for a signal before proceeding?
[12:40:02] <jthornton> m100 code?
[12:40:28] <anonimasu> yeah
[12:41:14] <anonimasu> ie replace my G??.P 18 to a Mxxx code so I can let cl dwell, and then start cutting
[12:41:23] <jthornton> I don't see why not, it waits till exit
[12:42:22] <jthornton> do you have an input that says "I'm ready"
[12:43:02] <anonimasu> no, this is a oxyfuel torch
[12:43:13] <anonimasu> my big issue is this, that preheat time changes as you cut because the sheets get hot
[12:43:25] <jthornton> I see
[12:43:36] -!- Calyp [Calyp!~Caly@unaffiliated/calyptratus-tzm] has joined #emc
[12:44:07] <anonimasu> probably there's something smart you can do to comp for it, but I dont know how :)
[12:44:12] <jthornton> so you need to change the preheat time on the fly as it cuts parts out of the sheet
[12:44:23] <anonimasu> yeah
[12:45:26] <anonimasu> how would I do this, make a custom M code(Python script) tehen invoke a cl routine by that?
[12:45:28] <jthornton> let me think a bit... I'm on my first cup of joe and it is still dark outside
[12:45:31] -!- mhaberler [mhaberler!~mhaberler@195.191.253.94] has joined #emc
[12:46:01] <anonimasu> tho I might aswell just dwell in the py script since it's not that critical +/- a second or so dosent really matter
[12:46:18] <jthornton> on my plasma I have a touch off subroutine and I pass it several things including pierce delay, so I move to a point then call that sub then when it is done start cutting
[12:47:00] <jthornton> but my delay is fixed :/
[12:47:12] -!- packrat has quit [Ping timeout: 248 seconds]
[12:49:38] <jthornton> so yea a M1xx with timer that can be changed by a pyvcp spin box on the fly... hmmm
[12:50:11] <anonimasu> and how would you do that? script or python?
[12:50:44] -!- vladimirek [vladimirek!~vladimire@adsl-dyn-132.95-102-159.t-com.sk] has joined #emc
[12:50:46] <anonimasu> im thinking maybe I should just make a userspace component that has a set input that sets pause...
[12:50:54] <anonimasu> and waits for a time and unsets it,
[12:51:03] <anonimasu> that will allow me to override it with the play button also,
[12:51:06] <anonimasu> if I want to force start
[12:51:30] <jthornton> yea you could have the delay input and an override input on the comp
[12:51:50] <jthornton> like an on delay timer
[12:52:15] <jthornton> call the comp in your M1xx code and when it is done exit
[12:52:15] <anonimasu> but what is the easiest way..
[12:52:24] -!- packrat [packrat!~packrator@c-98-209-146-133.hsd1.mi.comcast.net] has joined #emc
[12:52:28] <awallin> http://linuxcnc.org/docs/2.4/html/man/man9/oneshot.9.html
[12:52:37] <jthornton> have someone else code it :)
[12:52:59] <anonimasu> problem is I have parts to cut, and i dont have time to play too much today :S
[12:53:06] <anonimasu> like 150 parts..
[12:53:25] <anonimasu> and they are computer nested so they are very tight so it heats up quickly
[12:54:21] <jthornton> looks like the oneshot is the comp you want to use
[12:54:39] <anonimasu> looks like a shell script that grabs a hal pin, and calls sleep is the easiest quick and dirty way.
[12:54:51] <anonimasu> :)
[12:54:59] <anonimasu> and then spend the weekend to fix it properly
[12:58:31] <anonimasu> ie,
[12:58:59] <jthornton> do you have a pyvcp panel now?
[12:59:03] <anonimasu> sleep $(halcmd -s show sig preheat_time)
[12:59:06] <anonimasu> no not yet
[12:59:29] <anonimasu> something similiar to that
[12:59:34] <Spida> anonimasu: a friend works for a company doing Finite Element simulations on heat distribution during welding and similar stuff - that sound exactly like what you need *g*
[13:00:11] <anonimasu> hehe :D

[13:16:58] <jthornton> well I have a slider in a pyvcp panel connected to oneshot.width... that didn't take long
[13:20:12] <jthornton> only thing I don't see how to do is to wait for oneshot to complete in the M1xx script
[13:20:57] * jthornton goes to look to see how a bash script does if else endif
[13:22:29] <awallin> jthornton: can you read the one-shot pin with m66? http://linuxcnc.org/docs/2.4/html/gcode_main.html#sec:M66-Input-Control

[13:22:33] <jthornton> if then else fi that is interesting
[13:22:44] <jthornton> I don't know
[13:24:14] <jthornton> I think you can
[13:24:22] <jthornton> that would make it real simple

[13:48:14] <jthornton> awallin: the only trick is to use out-not and for some reason there must be some movement between M62 and M66
[13:48:23] -!- packrat has quit [Ping timeout: 253 seconds]
[13:49:37] <awallin> m62 is synchronized with motion, it will probably take effect at the start of a move
[13:49:48] <awallin> m64 would do that without motion
[13:49:53] <awallin> I think
[13:50:58] <jthornton> M64 & M65 happen immediately as they are received by the motion controller. They are not syn-
[13:51:00] <jthornton> chronized with movement, and they will break blending.
[13:51:33] <jthornton> The actual change of the specified outputs will happen at the beginning of the next motion command. If there is no subsequent motion command, the queued output changes won’t happen. It’s best to always program a motion g-code (G0, G1, etc) right after the M62/63.
[13:51:43] <jthornton> right from the manual :)

[13:54:29] Jymmmmmmmmmm is now known as Jymmm
[13:55:38] <jthornton> nothing I just noticed a phone store advert saying they laser engrave phones
[13:56:06] <jthornton> might be something for you to get into if your not all ready doing it
[13:56:40] <jthornton> awallin: I also noticed that I need to have the min setting for the slider to something greater than 0
[13:57:11] <Jymmm> If I had a retail shop, sure. Need to have their phone for a while and most act as if I want to borrow their kidney for a couple of days =)
[13:57:21] <jthornton> lol

[14:03:37] <jthornton> that was fun
[14:03:50] <jthornton> that's cool
[14:04:33] <Jymmm> Yeah, since it's anodized aluminum, they engrave right on it. not on a snap-on cover.

[14:22:36] <Loetmichel> hmmm... that reminds me: i have to put my IBM x60 in the CNC engraver and make a Cyloner-head-formed hole in the LCD cover...
[14:22:56] <Loetmichel> wanted to do that since myfirst Laptop ;-)
[14:25:35] <FinboySlick> And IBM ones have such nice flat surfaces, begging for CNC work.
[14:27:15] <Loetmichel> yes
[14:27:33] <TekniQue> I'd love to see something like that on macbook pro's slick surfaces
[14:27:51] <Jymmm> TekniQue: ?
[14:28:04] <TekniQue> just saying
[14:28:06] <FinboySlick> Heh, I'd make a 'mistake' and dive all the way through.
[14:28:38] <Jymmm> TekniQue: No, I didn;t understnad what you said, did you see the photo I posted?
[14:28:41] <TekniQue> the mb pro has a nice finish, it'd be neat to engrave the top of it
[14:28:50] <TekniQue> I was commenting on what Loetmichel said
[14:29:05] <Jymmm> TekniQue: http://powercordlabs.com/wp-content/uploads/2011/08/macbook_art1.jpg
[14:29:24] <TekniQue> oh, neat
[14:29:29] <Loetmichel> FinboySlick: THAT mistake i did a while ago
[14:29:40] <TekniQue> you must have posted that before I joined
[14:29:50] <Loetmichel> mounted a CDrom inside the display of an old Canen BN850
[14:30:04] <FinboySlick> Loetmichel: On a macbook? Bet the trendy owner needed an extra latte enema to get over it.
[14:30:05] <Jymmm> jthornton: http://img352.imageshack.us/img352/4333/josegirl28ez.jpg
[14:30:10] <Loetmichel> ... cutted thro the foil cable for the LCd :-(
[14:30:20] <Jymmm> TekniQue: http://img352.imageshack.us/img352/4333/josegirl28ez.jpg
[14:30:32] <TekniQue> nice
[14:30:47] <TekniQue> is that an etching?
[14:30:56] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=187
[14:30:57] <Jymmm> No, it's laser engraved
[14:31:05] <TekniQue> sweet
[14:31:25] <FinboySlick> Loetmichel: Hehehe.
[14:31:31] <Loetmichel> you can still see the soldered foil cable
[14:31:32] <FinboySlick> That's a nice oops.
[14:31:59] <Loetmichel> cutting through the display cover and mounting the CD: 1 hour.
[14:32:17] <Loetmichel> repairing the fine pitch foil with 30++ wires: one day ;-)
[14:32:28] <TekniQue> haha
[14:33:11] <TekniQue> I thought they stopped using foil to connect hinged displays a while ago
[14:33:29] <Loetmichel> that is an OLD canon BN 750
[14:33:39] <Loetmichel> P1-200Mhuz or so
[14:33:43] <Loetmichel> -u
[14:33:55] <Loetmichel> and with a printer underneath the keyboard
[14:34:03] <Loetmichel> so no room in the base for a cdrom
[14:34:12] <Loetmichel> hence the mount in the display
[14:34:20] <TekniQue> ah
[14:34:32] <TekniQue> what do you need a cdrom for?
[14:34:55] <Loetmichel> the 44 wires from the cdrom to the ide-controller was done in a slpt second, compared to the foil repair ;-)
[14:35:03] <Loetmichel> split
[14:35:35] <Loetmichel> TekniQue: 'cause the USB cdroms wwerent invented at that time ;-)
[14:35:43] <TekniQue> I have repaired foil ribbons before, it's no fun
[14:36:17] <TekniQue> and they're very prone to breaking again if it's not done well
[14:37:09] <Loetmichel> it IS done well
[14:37:30] <Loetmichel> the laptop is still in use as a server somehre i think
[14:37:49] <Loetmichel> and my nick isnt choosen randomly ;-)
[14:38:03] <TekniQue> heh
[14:38:06] <TekniQue> what does it mean?
[14:38:22] <Loetmichel> (loetmichel = german for Soldering michael)
[14:38:28] <TekniQue> ohh
[14:38:56] <Loetmichel> i had my first own soldering iron at age 5
[14:39:03] <Loetmichel> ... i am now 42
[14:39:05] <Loetmichel> ;-)
[14:39:13] <TekniQue> I think I was 7 when I got mine
[14:39:25] <Loetmichel> so i have a little of a head start ;-)
[14:39:29] <TekniQue> yup
[14:39:35] <TekniQue> I'm 27 now
[14:40:35] <Loetmichel> ... doing things like this, with the soldering tip in the picture: http://www.cyrom.org/palbum/main.php?g2_itemId=3135
[14:40:39] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=3132
[14:40:43] <Loetmichel> ;-)
[14:41:46] <TekniQue> yeah I don't think superfine tips have much to offer
[14:41:58] <TekniQue> the greatest tool I got was the stereo microscope
[14:42:26] <TekniQue> being able to actually see what was going on changed everything
[14:42:55] <TekniQue> no more wondering is that a bridge or is it just a speck of dust caught in flux
[14:43:43] <Loetmichel> made this a while ago for a friend who wanted to know how to change a C: http://www.cyrom.org/MC/entloet2.wmv
[14:44:39] <Loetmichel> i started recently to use a usb cam with the focus turned all the way out as a magnifier
[14:45:09] <Loetmichel> ist really stunning how much magnifying you get with a 10$ webcam and a 19" screen...

[20:43:11] <FinboySlick> awallin: Had you tried using taskset to move RTAI processes to the isolated core?
[20:44:13] <awallin> I only tried "isolcpus=1" and that gave 7-8knsec jitter under load
[20:44:25] <awallin> is taskset something else?
[20:44:43] <FinboySlick> awallin: Yeah, same as me. shifting the tasked to the isolated CPU gave me a rock-solid 5885.
[20:45:38] <FinboySlick> awallin: isolcpu tells the linux scheduler not to use a specific core for anything... That leaves it free for RTAI... But since isolcpu does its job, RTAI never gets to use that freed core.
[20:45:39] <awallin> nice. did you add some info to the wiki about this?
[20:46:11] <FinboySlick> awallin: Not yet, I didn't think I was the first to think of it. That would likely give quite a boost to any multi-core platform.
[20:46:25] <awallin> would that work with other multi-core machines, like an i7-"screamer"?
[20:47:02] <FinboySlick> awallin: Well, it won't solve everything. But if you get good results with no load and it goes bad under load, this would likely prevent it from going bad under load.
[20:47:54] <awallin> ok. someone should write a program that automagically sends latency-test results to an online database. too much work entering them by hand on the wiki...
[20:48:23] <FinboySlick> awallin: That's a bit tricky because they're threads launched by the modules, not userspace.
[20:48:43] <FinboySlick> You can't just launch them using taskset. You have to change their affinity once they're launched.
[20:49:29] <FinboySlick> awallin: I'm working on a hack for /etc/init.d/realtime that would do that anytime it is started.
[20:49:39] <FinboySlick> But it's a bit ugly.
[20:50:52] <FinboySlick> I'll also investigate further, that might mean we don't need to disable hyperthread completely.
[20:51:14] <awallin> could you post instructions for the taskset config to the mailinglist, I could try it on the atom and maybe some other machines with a liveCD
[20:54:52] <FinboySlick> awallin: I probably will later tonight. In the meantime, when you start EMC or the latency test, you'll get four processes created by the modules. You can use taskset to set their affinity to the core you isolated with isolcpu. Note that isolcpu starts with 0 and taskset -c starts with 1. So for isolcpu=1 you want taskset -pc 2 <realtime_pid>
[20:55:32] <FinboySlick> You do that for all four RT processes.

[22:00:47] <andypugh> http://zenstoves.net/Supplies/KnockoutPunch.jpg
[22:01:02] <archivist> drill a hole and a bolt forces the punch through
[22:01:43] <andypugh> I had 60 holes to make, 28mm from two edges. Drilling all those holes was going to be tedious.

[22:29:30] <elmo40> hey guys. I have a question. I was told Sandvik doesn't produce the TLT-4R inserts anymore (threading) how would I find someone who makes something for their holders? Here is what they look like (note the Discontinued)
[22:30:33] <elmo40> I know there are other manufacturers that make inserts for other holders not their own. Tungaloy comes to mind.
[22:30:51] <elmo40> http://www.grainger.com/Grainger/SANDVIK-COROMANT-Carbide-Threading-Insert-5FEV7
[22:31:09] <archivist> is the form an iso standard
[22:31:24] <elmo40> yes. 60deg regular thread
[22:31:50] <archivist> no i mean the insert shape
[22:32:25] <archivist> I dont remember seeing that insert shape before
[22:32:29] <JT-Shop> time for new tooling :(
[22:33:27] <archivist> is that discontinued by sandvik or just the distributor
[22:33:38] <elmo40> sandvik stopped making it
[22:33:47] <elmo40> we make 8mm pitch large diameter threads.
[22:34:13] <elmo40> for the most part we use a triangle insert, but sometimes we have to get it right up to an edge
[22:34:23] <elmo40> and those tlt inserts work great for it.
[22:35:21] <archivist> see http://www.grainger.com/Grainger/SANDVIK-COROMANT-Carbide-Threading-Insert-5FEV2?cm_sp=IO-_-IDP-_-BTM_BTB05209020&cm_vc=IDPBBZ2
[22:35:45] <elmo40> too small
[22:36:43] <elmo40> I forgot to mention, the thread height is 4.33mm
[22:37:05] <elmo40> some times as large as 4.5mm
[22:37:35] <elmo40> this is why a triangle insert works for some of our applications.
[22:38:40] <elmo40> found some: http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=190554586593 but that is a photo of the 4L, not 4R... I hope it is just a generic image.
[22:38:58] <elmo40> very nice price, too. shipping will make them expensive, though.
[22:39:00] <archivist> seems to still be in the sandvik pdf
[22:40:46] <elmo40> ya, I see them http://www2.coromant.sandvik.com/coromant/downloads/tailor_made/US/partgroov.pdf
[22:41:14] <elmo40> Top-Lok inserts.
[22:41:35] <elmo40> can make the tool a grooving tool or whatever. very nice design.
[22:41:38] <elmo40> versatile
[22:42:53] <archivist> I have home brewed holders for threading inserts so far only the triangle types
[22:51:45] <JT-Shop> I'm convinced that the archivist can make anything from nothing...

[22:58:55] <JT-Shop> well almost anything from very little :)
[22:59:09] <elmo40> we make tooling all the time because the boss doesn't want to buy anything.
[22:59:20] <andypugh> Well, yes, that will teach me to read to the end first.
[23:00:14] <andypugh> Strange, identical title and photo, different price.
[23:00:31] <elmo40> 12' long boring bars... angled holders for odd parts... extensions for extensions. its crazy. takes more time then if we had the actual tools to work with :-P
[23:00:45] <elmo40> same company, too! very weird
[23:00:58] <andypugh> 12' long!
[23:01:15] <elmo40> yes
[23:01:28] <andypugh> What do you make?
[23:01:30] <elmo40> I bore sleeves that are 6-7' long
[23:01:31] <JT-Shop> my boss makes me buy tooling cause I take too long making it
[23:01:36] <elmo40> rock crushing equipment :)
[23:02:00] <JT-Shop> oh fun you get to work with AR plate?
[23:02:01] <elmo40> eccentric rotating hammers
[23:02:09] <elmo40> ya... fun stuff >_<
[23:02:21] <elmo40> with no ceramics.
[23:02:32] <archivist> elmo40, the local rock crushing machine company was bought by sandvik
[23:02:41] <andypugh> Well, I can't imagine that 12' long boring bars are off-the-shelf items anywhere. I made an 18" long once, out of a rad drill ::)
[23:02:47] <andypugh> (road drill)
[23:03:18] <elmo40> out of a drill? interesting

[23:04:12] <elmo40> but I can't order it
[23:04:15] <andypugh> Well, more a chisel, really.
[23:04:58] <elmo40> and what do you mean they were bought by sandvik? is the material being mined suitable for tooling?

[23:16:08] <andypugh> Yes, carbide. Silicon steel workpiece. 1000rpm (because I go deaf otherwise)
[23:16:09] <JT-Shop> and material your cutting?
[23:16:14] <elmo40> and rpm
[23:16:38] <Tom_itx> logger[psha]
[23:16:58] <elmo40> not much... 0.002" per flute per rev for that small a cutter.
[23:17:20] <elmo40> silicon steel is high wear stuff, right?
[23:17:27] <JT-Shop> chip load about .0005 to 0.001" per tooth for that small of a cutter
[23:17:34] <andypugh> Seems to machine OK actually.
[23:17:41] <elmo40> what do you run now?
[23:17:53] <andypugh> Random numbers
[23:17:54] <JT-Shop> is it a "free machining steel"?
[23:18:01] <andypugh> It's transformer steel
[23:18:19] <andypugh> 0.5mm thick
[23:18:32] <andypugh> I will probably cut two parts at a time thought.
[23:18:35] <andypugh> (though)
[23:19:14] <andypugh> Hmm, so 50mm/min at 1000rpm seems about right?
[23:19:28] <JT-Shop> .1 dia, 2 tooths 0.001 FPT 1000 rpm 2 IPM 26 SFM
[23:20:03] <JT-Shop> aye
[23:20:18] <elmo40> I haven't worked with such small tooling in ages :P
[23:20:32] <elmo40> my lightest chip load is 0.060" !
[23:25:14] <JT-Shop> I use 0.125" end mills regularly
[23:25:35] <andypugh> I am mainly asking because I have no feel for it myself. I am a bit vague on milling in general, I am more of a lathe enthusiast.
[23:25:41] <JT-Shop> got to keep the DOC light to keep from flexing the dang things
[23:26:06] <JT-Shop> I use about 0.025" DOC on 0.125"
[23:26:27] <andypugh> That's about 2 thicknesses of my material.
[23:26:50] <JT-Shop> what are you making Andy?
[23:26:54] <andypugh> (hmm, no wait, that't the wrong way round)
[23:27:06] <andypugh> I am making stator laminations.
[23:27:16] <JT-Shop> cool
[23:27:34] <JT-Shop> yea, that is 0.635mm to you guys
[23:28:26] <andypugh> I punched the centre holes earlier, and made a jig to clamp them down through that hole (cutting out of an edge-clamped sheet didn't work too well)
[23:29:30] <JT-Shop> does SheetCam do nesting well now?
[23:29:31] <andypugh> I am actually wondering if I could make a single-pole punch, and index round with a rotary.
[23:30:08] <andypugh> JT-Shop: I don't know. It lets you drag things around, but I don't think there is any auto-nesting.
[23:31:19] -!- emcrules_d510 has quit [Ping timeout: 245 seconds]
[23:33:47] <andypugh> Hmm, to climb cut or not climb-cut. I think not, in this case.
[23:34:21] <JT-Shop> ballissta trigger http://imagebin.org/185484
[23:35:05] <JT-Shop> crap my typing is slurred
[23:36:01] <andypugh> It's not immediately obvious to me how that works. Is part missing? (the hook for the string?)
[23:36:19] <JT-Shop> yes, it is in the mill atm
[23:36:43] <JT-Shop> it bolts on the sear and covers the slot
[23:37:03] <andypugh> How do you navigate to a network drive in the Ubunto file-select dialogs?
[23:37:06] <JT-Shop> note the safety pin hole in the sear
[23:37:27] <JT-Shop> Places/Network
[23:37:50] <andypugh> There isn't a "places" in the file selector
[23:38:30] <JT-Shop> if your all ready in the file browser it is Network Servers on the left side
[23:38:33] <andypugh> I was hoping there was a way to save direct from SheetCAM onto the CNC machine.
[23:38:44] <Jymmm> JT-Shop: the one with the lanyard hole ?
[23:38:45] <JT-Shop> oh sheet cam
[23:38:57] <JT-Shop> the hole in the bottom part
[23:39:15] <andypugh> It's the same in any application, I can't figure out how to do it with gedit either.
[23:39:24] <JT-Shop> hmmm
[23:39:29] <Jymmm> JT-Shop: tis ok, I have no clue what part is what in that pic =)
[23:39:58] <Jymmm> andypugh: is sheetcam on windows?
[23:40:05] <andypugh> No.
[23:40:10] <JT-Shop> aye, seems to be lacking Andy
[23:40:12] <Jymmm> then where?
[23:40:30] <andypugh> Jymmm: Another (different) Ubuntu machine
[23:40:36] <JT-Shop> Jymmm: just remember this photo when you see the completed ballista photo
[23:40:54] -!- sumpfralle has quit [Ping timeout: 245 seconds]
[23:40:57] <Jymmm> andypugh: Ok, do you have a share setup on your cnc box?
[23:41:09] <andypugh> There seems to be (as far as I can see) no way to open or save a file from a network share with any application under Ubuntu.
[23:41:40] <andypugh> Yes, it is even an entry in my "Places"
[23:41:46] <Jymmm> andypugh: You have to setup samba (or another sharing protocol) on your cnc box before hand
[23:42:12] <Jymmm> then share a folder on it that other boxes can connect to.
[23:42:42] <andypugh> Yes, I can see it there in the "Places" Menu, but where does it live in the file system?
[23:42:52] <Jymmm> your "Places" will show ALL boxes on your network it can see, that doens't mean it's setup for sharing though.
[23:43:22] <andypugh> No, it sees the folder called "CNC Drop"
[23:43:51] <Jymmm> ok, so in sheetcam file dialog navigate to it
[23:44:05] <andypugh> I can relatively easily save the file to disk, then move it to the network share, but I was hoping there was a way to save it direct to the network share.
[23:44:13] <Jymmm> have you already attached to that network share ?
[23:44:36] <Jymmm> you have to mount that share on your sheetcam box
[23:44:43] <andypugh> That's my question, _how_ do I navigate to it in the Sheetcam file dialog?
[23:44:52] <Jymmm> mount it
[23:45:52] <andypugh> Hmm, I am not sure I know how to mount it.
[23:45:56] <Jymmm> Once mounted, you should see it within sheetcam as then it'll appear "local"
[23:46:36] <andypugh> In /mnt ?
[23:47:01] <andypugh> I have the folder open in the file browser, I clearly have access.
[23:47:26] <andypugh> Do I need to open a shell and mount it?
[23:48:02] <andypugh> (At this point it is much easier to save the file temporarily to disk and then move it across in the file browser)
[23:51:48] <andypugh> Aha! the internet has the answer. You need to browse to the hidden .gvfs folder in the home directory. How user-friendly!
[23:54:29] <andypugh> The same dodge works in EMC2 too. Excellent. (and, at the same time, rubbish)
[23:55:21] <Tom_itx> they only want the smart ones using it
