#emc | Logs for 2011-05-22

[00:00:22] <FinboySlick> JT-Shop: I'm not there yet. Just curious about the types of results most people get here.
[00:00:34] <JT-Shop> depends on the latency
[00:00:51] <JT-Shop> just a sec and I'll run it
[00:02:32] <JT-Shop> for a good computer latency of 10,000 the step frequency can be 40,000 Hz
[00:02:54] <JT-Shop> 20,000ns latency gives you about 28,000 Hz

[00:06:10] <FinboySlick> First result sounds pretty sweet. I hope I can hit that.
[00:06:28] <FinboySlick> Anyway, back to this pump exploration. I'm eager to get to the computer stuff.

[00:13:49] <AC-130H> how good is this Tooling U online school?
[00:15:34] <JT-Shop> never heard of it but that don't mean nothing
[00:15:40] <JT-Shop> what is it?
[00:16:41] <AC-130H> http://www.toolingu.com/default.aspx <-- has courses in stuff like machining, welding, workholding, et al
[00:17:05] <AC-130H> my concern is... ok, you take those classes, but what about memory retention if you do not have access to the tools?
[00:18:53] <JT-Shop> yea, if your not going to use it in practice everyday...
[00:19:14] <AC-130H> i could see using that with OJT
[00:19:17] <JT-Shop> me all I have to do is take a nap and I'm in a new world :/
[00:19:38] <JT-Shop> yea, OJT plus that would make it sink in better
[00:20:16] <JT-Shop> it's kinda like programming, I never could learn any of it till I had something I needed to get done then I learned python
[00:20:41] <AC-130H> was gonna go out talk to some machine shops here yesterday but i had a migraine headache... damn this weather
[00:20:55] <FinboySlick> JT-Shop: Nice choice of language. Python is such an elegant thing.

[00:21:52] <JT-Shop> I did a bunch of the simple g code generators on the wiki while building my plasma cutter
[00:22:05] <AC-130H> ya?
[00:22:06] <AC-130H> nice
[00:22:25] <AC-130H> i thought i saw something about a blender-to-gcode generator
[00:22:44] <AC-130H> not too sure, because blender3d is not cad/cam optimized

[00:24:29] <AC-130H> hmm... arc buddy would prolly help me visualize i,j,x codes
[00:25:01] <JT-Shop> yea, that is what I did that for... now I just need the coordinates and I'm good
[00:25:20] <JT-Shop> I would guess at it then run Arc Buddy to see my mistakes
[00:26:06] <JT-Shop> people keep adding to that page... that's cool
[00:26:15] <AC-130H> *nod*
[00:26:36] <AC-130H> oh, tooling U also teaches g-code in the cnc milling section
[00:26:44] <JT-Shop> I do most ops on the lathe with ngcgui now
[00:27:00] <AC-130H> lathe uses X and C axes?
[00:27:08] <JT-Shop> X Z
[00:27:15] <AC-130H> ok
[00:27:27] <AC-130H> i knew it didnt use one of the axes that a mill does, typically
[00:28:10] <JT-Shop> and you have to lay on the floor and look at the ceiling to make sense of arcs or cutter offset :)
[00:29:03] <JT-Shop> if you take a mill and twist it 90Β° CW and lay it over to the left you have a lathe
[00:29:24] <JT-Shop> then Y+ is on the floor looking up
[00:33:55] <AC-130H> yeah, was wondering how to view the axes on a lathe
[00:34:24] <AC-130H> X would be going sideways in relation to Y?
[00:37:10] <JT-Shop> X goes away from you and Z goes left and right
[00:38:17] <AC-130H> ok, and y goes into/out of the headstock?
[00:40:41] <JT-Shop> the imaginary Y goes from the floor to the ceiling
[00:40:58] <AC-130H> ok
[00:41:07] <AC-130H> and the x is into/out of toolstock?
[00:45:29] <JT-Shop> X moves perpendicular to the spindle
[00:45:40] <JT-Shop> Z is parallel to the spindle
[00:46:55] <AC-130H> OH ok... i was viewing myself laying down on the floor with my body parallel to the ways, i gotcha now
[00:47:28] <AC-130H> gotta view myself laying down perpendicular to the ways
[00:47:34] <JT-Shop> that is where have to be to get the arc direction and tool offset correct
[00:48:56] <JT-Shop> The direction (CW, CCW) is as viewed from the positive end of the axis about which the rotation occours.
[00:49:34] <JT-Shop> When the XZ-plane is selected the positive end of Y is on the floor
[01:01:27] * JT-Shop calls it a night
[01:01:38] <AC-130H> take care
[01:01:58] <JT-Shop> thanks, you too
[01:02:16] <AC-130H> yeah. i try my best these days.

[11:11:07] <jthornton> Tom_itx: I have speed buttons on my pendant and unless they are pressed the joy sticks do nothing
[11:15:17] <Jymmm> you guys ever do any heavy gauge sheet metal work?
[11:15:54] <jthornton> describe "heavy gauge"
[11:16:15] <Jymmm> .050"
[11:16:28] <Jymmm> maybe a bit thicker
[11:19:05] <Jymmm> jthornton: .050" maybe a bit thicker
[11:19:47] <jthornton> yea, I think I normally use 26 gauge for light weight stuff
[11:20:29] <Jymmm> jthornton: you ever do anything with lots of details/complex bends, tabs, and such?
[11:20:47] <jthornton> yea sometimes
[11:21:11] <Jymmm> jthornton: I'm wanting to basiclly make a PC Case (sorta) and wondering what I'm in for.
[11:21:12] <jthornton> that looks to be about 18 gauge
[11:21:31] <jthornton> you have a sheet metal box brake?
[11:21:45] <Jymmm> I have nothing but a drill press
[11:22:15] <jthornton> your in for lots of fun trying to bend it then
[11:22:51] <Jymmm> lol, maybe I could use aluminum sheet instead
[11:23:12] <archivist> no, send a drawing to a company get them to make
[11:25:05] <jthornton> here is what you need to bend 18 gauge http://www.grizzly.com/products/48-Pan-Box-Brake-12-Ga-/G0542
[11:26:01] <Jymmm> Hmmm, acrylic is looking more and more interesting =)
[11:26:03] <jthornton> it takes two guys to bend 48" wide 12 gauge on it... I know
[11:26:51] <Jymmm> oh joy
[11:27:41] <jthornton> I usually only use 14 gauge for boxes and covers I make with it
[11:28:46] <Jymmm> Yeah, ok. So scratch sheet metal off the list =)
[11:28:58] <jthornton> I also have this one for light stuff http://www.grizzly.com/products/48-Pan-Box-Brake-12-Ga-/G0542
[11:30:07] <jthornton> LOL I never could figure out where the back gauge went till I looked at that picture
[11:32:57] <jthornton> Jymmm: what the heck are you making?
[11:33:27] <Jymmm> jthornton: A 6-8 bay NAS box
[11:35:02] <archivist> just use flat sheet and angle for corners, no bending needed
[11:35:45] <jthornton> do you have a table saw Jymmm
[11:35:58] <Jymmm> small, but yes
[11:36:20] <Jymmm> s/small/portable/
[11:36:26] <jthornton> you can cut aluminum sheet on it
[11:36:44] <jthornton> or plastic and like archivist says use angles for the corners
[11:37:03] <Jymmm> Yeah, I've done aluminum on it before.

[12:39:39] <Gensor> Yo! What is the optimal sensor count per axis
[12:40:50] <micges> Gensor: you mean limits count?
[12:41:20] <Gensor> limits, home, etc
[12:42:20] <micges> if you have 2 limits, one is home/limit second is only limit and emc2 disallow you to travel by jog beyond hard limit switches
[12:42:45] <micges> (if you hit any by accident)
[12:43:05] <Gensor> two sensors then?
[12:43:56] <micges> Gensor: what are you trying to do?
[12:45:46] <Gensor> just trying to understand general scope before getting into the details on a grantry of some type
[12:46:21] <jthornton> you can have 1, 2 or 3 switches per axis if you want
[12:46:37] <micges> with gantry at least two per gantry axes
[12:46:43] <anonimasu> 3 is sane
[12:46:48] <anonimasu> one home switch and 2 limit switches
[12:46:57] <jthornton> one for each joint?
[12:47:08] <anonimasu> the heard ones is in case you get a runaway axis
[12:47:18] <micges> with gantry at least two per gantry joint*
[12:47:35] <anonimasu> the hard ones should turn off your drives..
[12:47:36] <jthornton> yea, I keep saying axis when I mean joint
[12:47:47] <anonimasu> so in case your encoder breaks or the wire to it you wont get runaway
[12:47:51] <anonimasu> (on a servo)
[12:48:01] <micges> and must be some hal error checking avoiding skewing of joints
[12:48:03] <Gensor> when I hear hard limit switch, I hear redundancy?
[12:48:15] <jthornton> micges: I forget is there a way to home a gantry other than homing each joint?
[12:48:16] <anonimasu> yes, you have soft limits that gets set after homing
[12:48:44] <anonimasu> that limits travel, but if something breaks and you get runaway you need something to save your machine frame
[12:48:48] <anonimasu> "hard" ones
[12:48:57] <micges> (this is must be for gantry with not so rigid construction)
[12:49:08] <anonimasu> huh?
[12:49:11] <anonimasu> no, it's general for any machine
[12:49:18] <anonimasu> with decently sized motors
[12:49:25] <anonimasu> if you crash a axis stuff breaks generally...
[12:49:33] <Gensor> anon: 5 sensors then
[12:50:01] <anonimasu> I guess for a gantry machine with dual drive like 6 sensors
[12:50:14] <anonimasu> 2 home sensors and 4 limits
[12:50:38] <anonimasu> tho, maybe one home and 4 limits would work
[12:50:43] <anonimasu> I dont know how you sync your gantry when you home it
[12:50:44] <Gensor> 2 home sensors for one joint with two screws?
[12:50:54] <anonimasu> how else will you sync the gantry?
[12:51:02] <anonimasu> so it dosent skew?
[12:51:05] <micges> jthornton: with gantry you can only home two gantry joints at once, there is no other way
[12:51:37] <jthornton> so you have to be in world mode to home the gantry if you have home switches
[12:52:00] <anonimasu> I can see it done with one swtich if you are sure your gantry isnt skewed enough to move the index pulse location(if you have servos)
[12:52:10] <micges> homing is only in joint mode
[12:52:20] <anonimasu> but still that relies on the fact that that's identical between axes..
[12:52:22] <anonimasu> brb
[12:52:46] <Gensor> a picture is worth a million words
[12:52:49] <jthornton> so you have to set the home sequence for both joints the same?
[12:53:03] <micges> jthornton: yes
[12:53:17] <jthornton> ok thanks
[12:54:08] <jthornton> just trying to get some knowledge on gantries... the manual is a bit frugal when it comes to gantries
[12:55:18] <micges> jthornton: gantry configs is better in ja3 but my lasts test with gantry on servos showed that it's need some coding
[12:55:47] <jthornton> if one side trips the switch before the other side what happens?
[12:56:35] <micges> its homed
[12:57:14] <micges> very important for gantries is to set initial home switches positions before first homing
[12:57:43] <micges> so they reach home switches on very simmilar time
[12:57:49] <jthornton> so the two joints just home independent of each other but at the same time?
[12:57:56] <micges> yes
[12:58:03] <jthornton> ah ok
[12:58:15] <syyl_> and the home switches should be positioned that the gantry is square when homed
[12:58:21] <micges> and balancing of home offset you remove eventually skeweing of machine
[12:58:23] <syyl_> not bend in some way
[12:59:00] <jthornton> that makes sense
[12:59:13] <jthornton> not perfect but workable
[12:59:14] <micges> syyl_: yes, and fine tuning of skewing is on home offset of one of joints
[13:02:27] <Gensor> second attempt, long axis of gantry with two screws/linear rails, you feel optimal setup is two limits and one home sensor per linear rail?
[13:04:48] <syyl_> limit switches are in my eyes optional
[13:05:12] <micges> on gantry limit switches is must be
[13:05:28] <syyl_> even our datron machines at work only have one home switch per side of the gantry
[13:07:02] <Gensor> micges: thanks, and the rigidity thing makes total sense for a gantry, and am glad to hear EMC can manage two servos on same axis without tearing itself apart
[13:07:40] <micges> I agree that some machine don't need limit switches becouse they're slow etc
[13:08:27] <syyl_> ok, thats a point
[13:08:32] <syyl_> the datron moves only 10m/min
[13:09:09] <micges> we've builded 6 machines with gantry emc2 on ja3 configs
[13:09:29] <Gensor> for emc to manage two servos without tearing itself apart, does it need encoder will hall support
[13:10:07] <pcw_home> If you can afford linear absolute encoders you dont need home switches either :-)
[13:10:09] <micges> some was quite speed (18m/min) and without limits it was very effective table destroy :)
[13:10:21] <syyl_> hr
[13:10:32] <syyl_> just dive, if something arkward happens :D
[13:10:51] <anonimasu> indeed that's why hard limits are a must :)
[13:11:03] <micges> absolute encoders needs emc2 support
[13:11:26] <anonimasu> hm.. should be possible to use endat or something with hostmot2
[13:12:03] <Gensor> micges Anon, thanks! any chance in sharing some pics of your gantrys?
[13:12:39] <pcw_home> SSI is supported in firmware and I have preliminary BISS firmware to try (sensor mode only for now)
[13:14:21] <jthornton> micges: does this sound correct to you? http://pastebin.ca/2066842

[13:15:03] <anonimasu> I dont have one :)
[13:15:09] <anonimasu> just logic thinking about them
[13:15:39] <Gensor> pcw: can you put that in layman's terms?
[13:15:41] <micges> jthornton: its ok
[13:16:25] <jthornton> ok, I created two basic stepper gantry configs as the one there now is really a plasma config with lots of extra junk
[13:18:33] <pcw_home> Just that there is support for two types of absolute encoders in HostMot2 (but no driver or EMC support yet)
[13:18:33] <micges> Gensor: last gantry 2.5m x 4.5m http://micges.wrzuta.pl/obraz/62LFENY7FDu/p4140214
[13:18:34] <pcw_home> Homing is different (or absent) with absolute encoders
[13:19:13] <Gensor> kinda small...
[13:20:05] <Gensor> what are you machining with that?
[13:21:06] <micges> http://micges.wrzuta.pl/film/1p5qsE6fDU8/cnc2
[13:22:32] <Gensor> micges: you and your team have some skill....
[13:23:55] <micges> thanks
[13:24:15] <micges> I think we use about 60% of emc2 full capabilities ;)
[13:24:35] <micges> regarding XYZ machines
[13:25:41] <Gensor> what was pcw saying earlier with the SSI and BISS
[13:27:01] <Gensor> maybe the new code that does not need limit switches if you have absolute encoders
[13:28:52] <jthornton> micges: are you using GladeVCP in that video?
[13:28:59] <Gensor> Im still looking for a good gantry plan for a 4x4ft or so
[13:29:28] <jthornton> what type of machine?
[13:31:54] <Gensor> router and or plasma
[13:32:22] <jthornton> pretty different requirements for those two
[13:32:44] <jthornton> plasma can be light and fast as there is no side loads
[13:32:56] <micges> jthornton: yes part of modified gladevcp
[13:33:06] <jthornton> cool
[13:33:39] <micges> I wanted to create gui from scratch but didn't have time for this

[13:45:53] <Tom_itx> pfft
[13:45:54] <Tom_itx> Half Full step
[13:46:52] <Gensor> where are these parameters used
[13:47:33] <Tom_itx> it's on an ancient stepper driver for a sherline mill
[13:49:58] <Tom_itx> i'm trying to figure out where all the signals go on this thing and if they are used
[13:50:39] <Gensor> recommend taking some pictures and putting them on photobucket and ask during a peak period on here
[13:50:40] <Tom_itx> there are "PARK" signals for each axis that go low only during a step pulse stream
[13:51:06] <Gensor> pictures of labes and cable ends etc
[13:51:09] <Tom_itx> i've hooked it to my la
[13:51:17] <Tom_itx> and figured out most of the stuff
[13:51:25] <Gensor> You could also post on a cnc forum
[13:51:52] <Tom_itx> i'm not even sure if the park signal is wired up
[13:51:53] <Gensor> do both and I am sure you will get all the info you need

[13:52:35] <Tom_itx> meh, i'll give it some time. i just started tracing signals last night
[13:54:34] <Tom_itx> ok, the "/H F" isn't even wired up
[13:54:37] <JT-Shop> Gensor: it can go up to 500IPM but I cap it at 450IPM
[13:55:17] <Tom_itx> which is odd. you'd think they would tie it one way or the other but it's left floating

[15:14:43] <FinboySlick> I get very good jitter figures for about 5 seconds, something kills them, then (if I reset), they go back to being good for another 5 seconds. I figure something (perhaps power management) kills performance but I'm not entirely sure where to look first.
[15:20:25] <JT-Shop> are you using a laptop?
[15:21:45] <FinboySlick> The laptop did something similar, yes. But I moved to an AMD based desktop. Didn't really expect the laptop to give a good score but i figured I'd test anyway.
[15:23:08] <FinboySlick> If it weren't for that, jitter would keep below 5000.
[15:23:38] <Tom_itx> JT-Shop, is it like a corn maze?
[15:24:00] <JT-Shop> ?
[15:24:10] <Tom_itx> your mowed trails
[15:24:46] <mrsunshine_> anonimasu, true, and its right under the column plate so the plate will strengthen it up also right there =)
[15:24:52] <JT-Shop> well kinda trails through the woods with a few acre sized open areas
[15:25:33] <JT-Shop> FinboySlick: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?FixingSMIIssues
[15:25:37] <Tom_itx> ok, i think i've figured out enough signals that i won't blow it up when i hook it up
[15:25:45] <JT-Shop> :)
[15:25:52] <Tom_itx> gonna go get a paper then try it
[15:26:02] <FinboySlick> JT-Shop: On it... Thanks :)
[15:26:29] <Tom_itx> well, i actually did have it hooked up once but got no output
[15:26:40] <Tom_itx> i blame the enable signal
[15:27:39] <Tom_itx> they have signals from the step generator that aren't used and lines on the stepper driver that you would think would go to them but are tied to gnd or not used at all
[15:28:22] <Tom_itx> and the half/full step pin is left floating

[16:07:42] <FinboySlick> I have a pretty powerful little board here with loads of gpio, might be worth experimenting with.
[16:07:44] <Tom_itx> i'm gonna get a snapshot of the mesa stepper signal so i can compare it with the exhisting one
[16:07:44] <Tom_itx> the current one is ~6΅s pulse with a 1.51ms period

[16:14:29] <archivist> you want all at the same time for coordinated movement
[16:15:00] <Tom_itx> no, it's for the axis selector switch on the pendant
[16:15:22] -!- michaeldexter has quit [Quit: michaeldexter]
[16:15:30] <Tom_itx> instead of using 4 io, i'd rather use 2
[16:16:57] <archivist> Im too used to a real machine with handles, I would want to move more than one axis at a time
[16:17:52] <Tom_itx> that could be set up with the same scheme
[16:18:03] <Tom_itx> the idea is to use fewer io to get there
[16:19:11] <Tom_itx> oh, JT-Shop i see what you did on your CHNC page

[23:37:00] <laidback01> hey folks, how goes it?
[23:37:25] <laidback01> I just loaded up the latest version of EMC from the downloads - well, latest ubuntu release with the EMC upgrades I guess.
[23:38:14] <laidback01> anyway, my machine is OK at best, jitter is 33542 on the servo thread and 8711 on the base thread. Is there anything wrong with the numbers being so far apart like that?
