#emc | Logs for 2010-01-16

[00:00:04] <danimal_garage> i dont have alot of control
[00:00:14] <danimal_garage> unless i put in a flow control
[00:02:06] <danimal_garage> hmmm i think i might have found an issue... i just pulled the turret off, and there's some wirey chips stuck in there
[00:02:24] <danimal_garage> might have slowed it down too much when it was lowering onto the hard stops
[00:02:24] <danimal_garage> brb gunna check it
[00:18:06] <christel> [Global Notice] Hi all, as you may be aware one of the reasons we're changing ircds is because hyperion attracts bugs like nectar does bees -- the recent splits were caused by software issues which I believe we have ironed out, and hyperion should just about manage to last us these last two weeks. Apologies for the inconvenience and good night!
[00:31:07] <danimal_garage> dammit i just cant win with this thing
[00:36:34] <andypugh> ?
[00:49:36] <danimal_garage> well i got it better, but not perfect
[00:52:33] <andypugh> Perfect is conclusion, the end to all hope of improvement.
[00:56:19] <danimal_garage> well i think i need perfection for a toolchanger
[00:56:25] <danimal_garage> that could be dangerous
[00:57:36] <andypugh> Perfection would be tool alignement to the Planck length, you can deal with more error than that,
[00:59:06] <danimal_garage> perfection would be if the right tool is in position
[00:59:29] <danimal_garage> if the wrong tool was there, or if it wasnt in position, i'd be in trouble
[01:01:26] <MarkusBec> MarkusBec is now known as MarkusBec_away
[01:01:56] <andypugh> As an aside, have you seen the hubs on Shimano R540 rear wheels? That's a nice shape.
[01:06:15] <danimal_garage> no havent been in the road bike loop for a while
[01:07:23] <danimal_garage> i'm more of a dirt guy
[01:08:46] <andypugh> That pattern is still current in MTB I think, but dropped from road. They are surprisingly tough. There is no force to buckle the rim because of the symmetrical spoking, and the rims are deep enough to not dent.
[01:12:05] <danimal_garage> yea, that wouldnt work well with disk brakes
[01:12:31] <danimal_garage> cant have radialy laced wheels with disks
[01:15:43] <andypugh> You can, but briefly,
[01:17:22] <andypugh> The rears have radial on the cassette side and tangential on the other. Campag do it the other way round. I think that Shimano have it right, having the low-angle, high-tension spokes not even trying to handle torwue.
[01:19:43] <danimal_garage> yea, the only wheel you can get away with that is on the front, on the right hand side
[01:21:57] <lilalinux> lilalinux is now known as lilalinux_away
[01:30:55] <andypugh> Which of the viewpoints do you think is correct?
[01:39:59] <danimal_garage> i think it should be tangential on the drive side in the rear at least, if using rim brakes
[01:40:31] <danimal_garage> radial isnt acceptable for dirt at all IMO, unless using rim brakes
[01:41:23] <danimal_garage> cradek: are you on? i must be missing something with this turret, mechanically
[01:41:57] <DaViruz> what's the benefit of radial spokes?
[01:42:14] <danimal_garage> it's stiffer with side loads
[01:42:29] <DaViruz> oh.
[01:42:30] <andypugh> Radial spokes look cool. There are no other benefits.
[01:42:48] <DaViruz> oh squared
[01:43:07] <danimal_garage> good for cornering
[01:43:28] <danimal_garage> like you said, you can achieve greater spoke tension
[01:43:37] <DaViruz> i'm guessing they don't handle torque as well as tangential spokes?
[01:43:57] <DaViruz> or at least with greater flex
[01:43:57] <danimal_garage> rotational torque doesnt go so well with radial spokes
[01:44:08] <danimal_garage> you end up with broken spokes
[01:44:22] <DaViruz> is there any other torque then rotational? :)
[01:44:33] <danimal_garage> side loads when cornering
[01:44:52] <andypugh> Torque in an orthogonal plane
[01:44:53] <DaViruz> i'm inclined to call that force
[01:45:15] <danimal_garage> whatever you want to call it
[01:45:34] <danimal_garage> i'm unedumicated in that department, i just know what works and what doesnt
[01:45:36] <DaViruz> but ok, thanks for clearing it up
[01:45:57] <DaViruz> (i'm not really a bike guy (i don't even own a bike), i was just curious)
[01:46:13] <ries> * ries is very happy with the result of the painting ... one layer more though : http://www.rvantwisk.nl/~systemcms/IMG_0227.JPG
[01:47:02] <danimal_garage> very nice ries
[01:47:40] <danimal_garage> jt-plasma: are you awake?
[01:48:01] <danimal_garage> or jthornton for that matter :)
[01:48:11] <danimal_garage> any one of your personalities will do
[01:50:14] <andypugh> Shimano do tangential on the non-drive side. Given the stiffness of the hub I think that makes sense, taking the torque through the low-tension spokes
[01:52:38] <andypugh> What's the hopper-and-belt thing in front of the calendar?
[01:55:02] <ries> danimal_garage: thanks.... tomorrow we can attach all electronics, steppers etc...
[01:55:11] <ries> and just maybe we can do some simple stuff :)
[01:58:22] <danimal_garage> wow that'll be cool. do you have you have emc mostly configured?
[01:59:01] <andypugh> Good Luck, but be prepared for it to take rather longer.
[01:59:24] <danimal_garage> yea, i've spent like 3 days on my toolchanger alone
[01:59:58] <ries> danimal_garage: yes I do.... I have been experimenting with that for quite some time
[02:00:07] <ries> and I can also generate good g-code from my CAD/CAM tool
[02:01:07] <ries> andypugh: I am well aware of that.. although my control box is ready and tested... and my cables are cut to length already
[02:02:02] <andypugh> Go for it then, I'll buy you a pint if you succeed
[02:06:16] <ries> andypugh: good :) I'll keep you on that :)
[02:09:19] <andypugh> ries: I think it can be done, through the magic of the intertubes
[02:10:16] <ries> intertubes?? I am not sure what they are :s
[02:11:11] <andypugh> it won't matter until 0200 GMT tomorrow.
[02:12:48] <ries> :)...
[02:13:11] <andypugh> If you get your machine tracing out the EMC test pattern my 0200 GMT 17th Jan 2010 I will get a pint of Old Speckled Hen to you. Partly because I like that sort of chalenge.
[02:15:52] <ries> Ooo....Hmmmm 2GMT is not possible for me...
[02:16:41] <andypugh> It's 24 hours away.
[02:19:36] <ries> Ahhh ok... 2gmt
[02:19:55] <ries> I was interpreting at 2PM GMT :)
[02:20:03] <ries> so... yeaa may be 2PM might work....
[02:20:22] <ries> We will see, I will not rush it... but would like to see you up to teh challange sending someting to Ecuador :D
[02:22:19] <andypugh> I;
[02:22:43] <kevinh_> kevinh_ is now known as kevinh
[02:23:13] <andypugh> I'll find a way. I work 6 feet from a Colombian.
[02:27:31] <ries> andypugh: that helps.... then you know how some things go overhere ....
[02:46:57] <danimal_garage> cradek?
[02:48:01] <danimal_garage> i'm lost
[03:08:42] <danimal_garage> $#%#$ERF##$@#$$#@$%^$#EW
[03:15:51] <cradek> danimal_garage: what's wrong?
[03:16:18] <cradek> I thought you had it all going
[03:21:58] <danimal_garage> thought so to, but it wont repeat
[03:22:39] <danimal_garage> it keeps going too far
[03:23:08] <cradek> did you get your ladder running every ms?
[03:23:42] <danimal_garage> back when i thought it was working, i was just getting lucky, it was settling down close enough
[03:23:45] <cradek> have you looked at the wsum signal while it's spinning, to make sure your feedback is clean and reliable?
[03:24:04] <danimal_garage> no
[03:24:12] <danimal_garage> didnt think of that
[03:24:15] <cradek> no to which?
[03:24:33] <danimal_garage> to the second question
[03:24:42] <cradek> ok, fire up halscope and see what's really going on
[03:24:50] <cradek> if it doesn't repeat, maybe something is noisy.
[03:25:06] <danimal_garage> ok i'll do that now
[03:25:27] <danimal_garage> like i was telling you before, i'm not sure if i have the wires hooked up right
[03:25:57] <danimal_garage> i know the sequence is right, but i dont know if i have it right regarding polarity
[03:26:38] <cradek> if it looks clean in halscope, it must be wired good enough...
[03:26:54] <cradek> I'm not actually sure what drives those signals - some ttl chip I think?
[03:28:05] <danimal_garage> yea, i have the wires from the signals going to the + pins on the 7i37, but if i hook anything up to the nagative pins on the 7i37, everything just reads false
[03:28:48] <cradek> you only wired one side of the 7i37 input and it works?
[03:29:40] <danimal_garage> the nagative pins are all piggybacked to eachother, but if i hook it up to the negative terminal on my PS, it just reads false, however the led's on the 7i37 are lit correctly (and get brighter when i hook up the negative lead)
[03:30:10] <cradek> they're tied to each other but nothing else?
[03:30:21] <danimal_garage> correct
[03:30:35] <danimal_garage> no other combination seemed to work
[03:30:42] <cradek> that can't be right - I bet you'll see in halscope that your signal is wrong for at least one part of the cycle
[03:31:02] <cradek> dang, wish I had made good notes.
[03:31:35] <cradek> maybe you should hook the signals to the - side, and hook the + side to the PS that runs the encoder thing
[03:33:25] <danimal_garage> if i put the nagative probe of my volt meter to the signal pin and the positive probe of my meter to the positive terminal of the PS, it shows 15v+
[03:34:16] <danimal_garage> but if i hook up the positive pins from the 7i37 to the positive terminal on the ps, all bits show false
[03:34:24] <danimal_garage> all pins*
[03:34:47] <cradek> what voltage is the encoder thing running on?
[03:35:05] <danimal_garage> 15v
[03:35:21] <danimal_garage> the power supply that was in the left cabinet
[03:35:43] <danimal_garage> 1.5A
[03:35:46] <cradek> it's gotta work one way or the other...
[03:35:58] <cradek> meter between output and gnd, or meter between output and +v
[03:36:50] <danimal_garage> hmm maybe 1.5A is too much for the 7i37 to take?
[03:37:20] <cradek> no, the 7i37 only draws the current it needs to turn on its optoisolators
[03:37:54] <cradek> can you unhook one (or more) outputs and make the thing spin?
[03:38:04] <cradek> then you can use your meter to figure it out.
[03:38:06] <danimal_garage> when the red led's are on, that means that pin is active, right?
[03:38:29] <cradek> I don't think mine has LEDs...?
[03:38:33] <danimal_garage> make the thing spin?
[03:38:41] <cradek> yeah so the output is changing
[03:39:02] <pcw_home> danimal: if the red input LEDS light, you have the input reversed
[03:39:03] <cradek> one of the two ways should show you changing signal on your meter
[03:39:11] <danimal_garage> cant i just put in a t20 or something?
[03:39:14] <cradek> oh???
[03:39:44] <danimal_garage> pcw_home: they were on no matter which way i had it i think
[03:39:56] <danimal_garage> i'll double check
[03:40:42] <pcw_home> The red LEDS are the OPTOs reverse protection diodes
[03:44:05] <cradek> ok I think I deciphered the wiring on mine. 7i37+ goes to +15, 7i37- goes to turret output. exactly like the proxes.
[03:44:40] <cradek> but I still don't see LEDs! they must be well hidden.
[03:44:46] <danimal_garage> ok i got mine backwards from that
[03:45:00] <danimal_garage> well they look like diodes if they arent lit
[03:45:07] <cradek> heh
[03:45:34] <danimal_garage> i'm gunna reverse them now
[03:45:50] <cradek> oh I see 'em now, duh
[03:45:58] <cradek> I guess I never lit any. I didn't notice them.
[03:55:16] <danimal_garage> ok so i guess i need to check the weighted sum now
[03:58:33] <maxster> #blender
[04:06:13] <danimal_garage> cradek: i'm getting clean signals from wsum
[04:06:19] <danimal_garage> 1-8
[04:06:59] <cradek> great
[04:07:05] <cradek> evenly spaced?
[04:07:09] <danimal_garage> yes
[04:07:17] <cradek> you did get ladder running at 1ms?
[04:07:46] <cradek> addf classicladder.0.refresh servo-thread
[04:08:17] <danimal_garage> it's at 1000000
[04:08:23] <danimal_garage> thats 1ms, right?
[04:08:35] <cradek> yes
[04:09:31] <cradek> when your ladder sees the matching feedback, what happens?
[04:09:35] <danimal_garage> ok i changed it, it said adf classicladder.0.refresh classicladder-thread
[04:09:51] <cradek> ah ok, maybe that was slower
[04:10:06] <danimal_garage> i was set at 50ms originally
[04:10:19] <cradek> yeah that would be bad. it goes too fast for that.
[04:10:24] <danimal_garage> (thats what i get for copy and pasting)
[04:10:28] <cradek> heh
[04:10:50] <cradek> when your ladder sees the matching feedback, what happens?
[04:11:41] <danimal_garage> well i had it so the compare box triggers a relay which triggers toolchange completed and latches turret stop
[04:11:48] <LoRez> [Global Notice] Alright, I'm sure you've all seen the drones bringing the noise. If you all will take the time to +R your channels, they'll have a much harder time of it.
[04:12:53] <cradek> I think you want to assert turret-stop, then wait a bit for it to settle against the stop, then turn off turret-up-and-spin, then wait for turret-is-seated
[04:13:20] <cradek> I think the pause for settling against the stop is important
[04:14:06] <cradek> without the pause, you're trusting your magnet instead of the stop to get it rotated properly for seating
[04:15:10] <danimal_garage> ahh ok
[04:15:29] <danimal_garage> i'll try that
[04:15:58] <cradek> the magnet should only tell you that the correct position is upcoming and you should get the turret-stop going
[04:16:53] <cradek> I'm off for the night - very full weekend coming up
[04:17:04] <cradek> you'll get it now I bet!
[04:17:37] <cradek> pcw_home: thanks for that help that was the real key to getting it wired right. apparently neither of us read the whole manual for the 7i37!
[04:19:09] <danimal_garage> yes, thanks alot to the both of you!
[04:19:17] <danimal_garage> have a good weekend
[04:19:49] <cradek> you too, goodnight
[04:21:26] <krushia_> krushia_ is now known as krushia
[04:52:37] <ries_> ries_ is now known as ries
[05:17:16] <danimal_garage> thank you once again cradek and pcw_home, i got it working and working well
[05:35:32] <danimal_garage> anyone have an emc post for mastercam for a lathe?
[06:09:15] <danimal_garage> and it's still working
[06:18:35] <Danimal> it was actually good that it took me that long, it got me pretty familiar with classicladder
[06:50:34] <kevinh_> kevinh_ is now known as kevinh
[07:19:25] <kevinh_> kevinh_ is now known as kevinh
[07:25:45] <MrSunshine_> is there any freestanding stuff for image 2 gcode that comes with emc ?
[07:25:50] <MrSunshine_> dont want to install emc on this computer
[07:25:58] <MrSunshine_> but this is the fastest computer i have to generate the toolpaths
[08:03:31] <kevinh_> kevinh_ is now known as kevinh

[11:07:52] <jthornton> danimal_garage: I'm awake now :)
[11:39:04] <EbiDK> EbiDK is now known as EbiDK|AWAY
[14:04:50] <Jymmm> jthornton: No, your not.
[14:17:28] <jthornton> Jymmm: :P
[14:18:13] <jthornton> * jthornton goes back to reading the 7i37 manual
[14:18:58] <Jymmm> reading is for wimps! just cram in wires till it works!
[14:26:42] <dan1mal> thats what i did
[14:27:14] <dan1mal> part of the reason i wasted a couple days :(
[14:28:11] <dan1mal> turret is working well now
[14:29:34] <dan1mal> jt-plasma: you can have my ladder if you'd like, but to be honest i dont know how kosher it is
[14:29:59] <dan1mal> it works fine, but i dont know if it's the best way to do it
[14:31:14] <cradek> you got it?
[14:31:20] <dan1mal> yes sir
[14:31:34] <cradek> slick
[14:31:44] <dan1mal> thanks to you and that tip you gave me yesterday
[14:32:08] <cradek> I thought it was pcw
[14:32:16] <cradek> was it the wiring or the ladder or both?
[14:32:23] <dan1mal> both
[14:32:33] <dan1mal> i had the timer wrong
[14:33:01] <cradek> aha
[14:33:14] <cradek> it gets tough when a bunch of different things are wrong
[14:33:39] <dan1mal> on yours, do you release the stop so it'll lower?
[14:34:14] <cradek> no, pretty sure it lowers with the stop in place
[14:34:39] <cradek> i don't remember if the stop is up or down when it's done though
[14:35:10] <dan1mal> i noticed on mine, if i left the stop engaged, sometimes it wouldnt lower all the way, so it turns off after a few miliseconds
[14:35:40] <cradek> weird
[14:35:59] <dan1mal> but i'm thinking about having it turn back on after the tool changed signal
[14:36:12] <dan1mal> just for extra peace of mind
[14:36:21] <cradek> wonder if there's a mechanical adjustment or something
[14:36:32] <cradek> I don't know even how the stop works - I've never had it apart
[14:36:56] <dan1mal> it's almost like a ratchet
[14:38:08] <dan1mal> ever see how a bicycle hub works?
[14:38:19] <dan1mal> with the little spring loaded pawl?
[14:38:44] <Jymmm> dan1mal: You read the manual?
[14:38:47] <cradek> yeah
[14:39:47] <cradek> Jymmm: "seems ok, since those lights are blinking" => read manual => "the lights that mean it's wired wrong are on"
[14:40:08] <Jymmm> cradek: DOH
[14:40:46] <dan1mal> same principal, except the air piston pushes the pawl against the ratchet, instead of the little spring like in a bicycle hub
[14:41:35] <cradek> I see
[14:41:41] <dan1mal> so if the holding force on the stop is pretty high, it could hang it up when it lowers onto the hard stops
[14:41:51] <cradek> then it drops down onto tapered dowels?
[14:41:56] <Jymmm> cradek: You would think that the/a light would be labeled "ERROR" or some such thing.
[14:42:14] <cradek> Jymmm: I think they are - in the manual :-)
[14:42:33] <dan1mal> cradek: yes, mine arent dowels, they are blocks and slots
[14:42:35] <Jymmm> cradek: Well, I meant on the device itself =)
[14:42:39] <dan1mal> but same difference
[14:42:59] <cradek> how do you take the turret off?
[14:43:10] <dan1mal> the 4 bolts on the top
[14:43:54] <dan1mal> pulls right off
[14:43:57] <cradek> duh
[14:44:03] <cradek> I'm off to find breakfast, bbl
[14:44:05] <dan1mal> but you cant see th stop
[14:44:18] <dan1mal> ok, adios, thanks again
[14:44:58] <dan1mal> all i need now is a mastercam post for a lathe and i can do a program
[14:45:12] <jthornton> dan1mal: I'd like to look at your ladder for sure
[14:45:15] <dan1mal> (unless i want to hand edit one)
[14:45:27] <jthornton> which version of mcam
[14:45:36] <Jymmm> jthornton: (perv)
[14:46:22] <dan1mal> mastercam x, but i can convert it if it's for an older version
[14:47:01] <jthornton> I messed with 9 a bit but only the mill one
[14:47:16] <dan1mal> yea i got a good post for the mill
[14:47:51] <jthornton> can you use a generic one for the lathe
[14:47:57] <dan1mal> i heard a regular fanuc post works, except the theading is off
[14:48:26] <jthornton> do you have any lathe posts?
[14:48:50] <dan1mal> i have the posts that come with mcam
[14:49:01] <dan1mal> one being a generic fanuc post
[14:49:17] <jthornton> same as I have I'd guess
[14:49:25] <dan1mal> probaby
[14:50:06] <dan1mal> it was too late to try it last night by the time i got the turret working, so i didnt mess with it much
[14:50:43] <dan1mal> i just wrote one in gedit just to try the turret in a program
[14:52:44] <jthornton> * jthornton heads up to the shop to start a fire
[14:52:54] <dan1mal> the good part about this taking me so long is hat i learned a bit about ladder
[14:53:03] <Jymmm> jthornton: Remember to use 2 gal of gasoline!
[14:53:24] <dan1mal> so maybe now i can tackle my mill's toolchanger
[14:53:50] <dan1mal> that would be bonerific
[14:56:26] <dan1mal> if my mill's atc worked, i'd die a happy man
[15:00:53] <Jymmm> If you die, can I have your mill?
[15:02:15] <dan1mal> sue you want it?
[15:02:22] <dan1mal> sure*
[15:02:32] <dan1mal> it's quite a bit of iron
[15:03:00] <Jymmm> Well, just wait till you get it working 100% before dieing
[15:03:13] <dan1mal> ok will do
[15:03:33] <Jymmm> thanks, that includes free shiping in your will too, right?
[15:03:57] <dan1mal> it's only right that it goes back to the area i bought it from
[15:04:19] <Jymmm> LOL, that's right, it did come from up here didn't it.
[15:04:24] <dan1mal> now, you have to drive 500 miles and pick it up in a 26 foot penske like i did
[15:04:33] <dan1mal> no*
[15:04:40] <dan1mal> yep, santa clara
[15:07:00] <dan1mal> well i'm off to do my morning duties
[15:07:03] <dan1mal> bbl
[15:07:06] <Jymmm> Hasta

[16:27:34] <kevinh_> kevinh_ is now known as kevinh
[16:46:46] <danimal_garage> cradek: i added a coil to turn the stop back on after the toolchange is completed
[16:48:48] <danimal_garage> so it turns off for a toolchange, turns on when it reaches the right position, the turret spin turns off, then the stop turns off for a few miliseconds and when the turret triggers the turret down sensor, it turns the stop back on
[16:50:02] <danimal_garage> i noticed i could rotate the turret slightly if i tried, so i figured it wouldnt hurt to have the extra holding force
[17:02:43] <mozmck> Is there a way to make axis come up full screen?
[17:03:21] <danimal_garage> full screen?
[17:03:26] <mozmck> Also, can I set the default jog speed to something faster than 17 in/min?
[17:03:37] <cradek> mozmck: yes, use devilspie
[17:03:46] <cradek> mozmck: yes, you can set it in the ini
[17:04:00] <danimal_garage> yes, in your ini, near the top, there is something that says default velocity
[17:04:01] <mozmck> haven't heard of devilspie I'll look it up
[17:04:46] <mozmck> ah, I see the velocity setting. what are the units - in/sec?
[17:04:51] <cradek> yes
[17:05:09] <cradek> everything in the ini is in, in/sec, in/sec2
[17:05:21] <mozmck> thanks! irc is great!
[17:05:46] <danimal_garage> mozmek... when you say full screen, do you mean when you click the square in the upper right hand corner (next to minimize and restore), it does nothing?
[17:06:27] <danimal_garage> i had that happen once when i didnt have the right monitor selected
[17:06:31] <cradek> mozmck: http://article.gmane.org/gmane.linux.distributions.emc.user/2385/match=devilspie
[17:06:47] <mozmck> I mean that when you start axis it is a small window, but I want it to start up using the whole screen instead of me having to manually maximize it each time.
[17:07:22] <danimal_garage> oh ok
[17:07:40] <mozmck> I have my router computer set to auto login and start emc automatically, and I'm too lazy to click the maximize button!
[17:07:51] <mozmck> actually, I do, but I don't want to...
[17:08:12] <danimal_garage> cradek: i have an assembly drawing for the turret, would you like a picture of it?
[17:08:23] <cradek> danimal_garage: yes please
[17:08:56] <danimal_garage> anything else? i have a parts list for the whole machine, it has a bunch of good assembly drawings
[17:09:52] <cradek> do you have a scanner? what would be super cool would be for you to scan that, I'd scan my servo amp docs, and we'd make it all available to everyone
[17:09:54] <mozmck> I'm routing end-grain hardwood, and I tried several carbide router bits including a freud diablo spiral; with less than good success.
[17:10:36] <mozmck> so I got an osc carbide end-mill from MSC and it works excellent!
[17:10:52] <cradek> mozmck: does it look different?
[17:11:01] <mozmck> not much.
[17:11:08] <cradek> funny how that is
[17:11:23] <mozmck> just higher quality, and more precise
[17:11:30] <danimal_garage> odd, osc is usually cheaper stuff too
[17:11:36] <archivist_emc> or new and sharp
[17:11:53] <mozmck> all the bits were new and sharp.
[17:11:55] <danimal_garage> cradek: i can scan them
[17:11:56] <jmkasunich> I bet HSS would work even better (sharper cutting edges), but it would wear out fast
[17:12:27] <mozmck> The onsrud HSS was good but it did dull quicker
[17:13:16] <danimal_garage> cradek: i have the original brochure for the machine, it's pretty funny, they have a picture of a guy in a white lab coat running it
[17:13:27] <danimal_garage> who runs a machine in a WHITE lab coat?
[17:13:40] <cradek> danimal_garage: don't you wear one of those? I do. I wear a tie under it too.
[17:13:42] <jmkasunich> actors
[17:14:22] <danimal_garage> hahaha, yea especially when running the manual lathe... i prefer to have the tie out though
[17:14:39] <cradek> the lab coat keeps your tie safe, duh
[17:14:59] <danimal_garage> the tie keeps my chuck polished when i lean over it
[17:15:47] <danimal_garage> i saw someone get wrapped up in a chuck once wearing a sweatshirt
[17:16:16] <danimal_garage> luckly it wasnt running too fast, and it was a little tiny south bend
[17:16:28] <cradek> yikes
[17:16:39] <danimal_garage> yea, scared the crap out of him
[17:17:17] <danimal_garage> i only got tangled once... i had the power feed going on my mill, and the handle caught the pocket of my hoodie
[17:18:03] <cradek> it's nice that cncs don't have handles
[17:18:26] <danimal_garage> i had to stall the power feed with my hands till the breaker popped. i was on the other side of the machine from the controls
[17:19:09] <danimal_garage> haha i take it you've never ran a prototrak... the y axis handle is at a very dangerous height and location
[17:19:35] <cradek> yuck
[17:20:14] <danimal_garage> forget to flip the handle in and hit cycle start, and you'll be singing soprano
[17:21:55] <danimal_garage> so once i hook up the lube and coolant, i'll take a vidoe of the machine in action
[17:28:43] <jthornton> my BP had handles on both X and Y, I took them off pretty fast...
[17:37:48] <jt-plasma> after some light reading in the 7i37's manual I think I have it figured out is this correct? http://i47.photobucket.com/albums/f163/johnplctech/7i37.jpg
[17:38:22] <danimal_garage> i ran a mitsubishi for a few years that had handles, but they turned encoders so they didnt move with the machine
[17:39:17] <danimal_garage> jt-plasma: the picture is too blurry to see what you have there
[17:39:28] <danimal_garage> what exactly are you unsure of?
[17:40:07] <danimal_garage> the pinout?
[17:41:17] <jt-plasma> no the plus and minus connections
[17:42:11] <jt-plasma> plus rail is on left and connects to plus on the I/O plug then on to the device correct?
[17:42:49] <danimal_garage> for the outputs, i just ran the + lead of the PS through the + pin on the 7i37 output, then the negative pin on the 7i37 goes to the positive lead on your load
[17:43:04] <jt-plasma> ok, that is what I thought
[17:43:28] <jt-plasma> :/ I forgot to scale and crop the image before I uploaded it
[17:44:23] <danimal_garage> it works just like a regular relay
[17:45:04] <danimal_garage> and the input works like a coil on a relay
[17:45:06] <jt-plasma> except for the sinking sourcing part
[17:48:06] <jt-plasma> hmm, according to my print I have 3 wire proxes
[17:48:34] <danimal_garage> yep
[17:48:53] <danimal_garage> positive and negative to power it, and a signal wire
[17:50:08] <danimal_garage> the signal sinks to negative when it's active
[17:50:10] <jt-plasma> looks like the signal is 0v so that is ok
[17:50:13] <danimal_garage> at least mine do
[17:50:32] <danimal_garage> yes, i ran them to my 7i42 breakout board
[17:50:56] <jt-plasma> I'm using 7i37's
[17:51:02] <danimal_garage> so when the signal is active, it shorts to ground
[17:51:15] <jt-plasma> that's what it looks like on the prints
[17:51:33] <danimal_garage> so you want your positive lead from your PS that is powering your proxies to go to the positive pin on your 7i37 input
[17:51:46] <jt-plasma> yes
[17:51:56] <danimal_garage> and the signal wire from your proxy to go to your negative pin on your 7i37
[17:52:09] <jt-plasma> ok
[17:53:00] <jt-plasma> if want you can email the ladder that you came up with for your turret
[17:53:28] <danimal_garage> just did
[17:53:37] <danimal_garage> see if it opens

[17:54:45] <danimal_garage> you should have it any minute, it's out of my outbox now
[17:54:57] <jt-plasma> ok
[17:55:27] <jt-plasma> just arriving now
[17:55:43] <danimal_garage> on that hal you sent me, he has the classicladder thread running at 50ms, that's too slow
[17:56:07] <danimal_garage> i have it at 1ms
[17:56:15] <danimal_garage> as does cradek
[17:57:47] <danimal_garage> also, i think he has the pins for the wsum set as in_not, i had to change mine to in
[17:58:54] <jt-plasma> same but different :)
[17:59:30] <danimal_garage> yea, just inverted :)
[17:59:59] <soapy> hi all
[18:00:07] <danimal_garage> i'm sure you'll find some flaws in my ladder, but it works
[18:00:13] <danimal_garage> i'll send you my hal too
[18:00:25] <soapy> got my little mill all set up, but I'm having a few issues
[18:00:37] <jt-plasma> there is always a zillion different ways to get things done in ladder :)
[18:00:47] <jt-plasma> ok, thanks
[18:01:01] <jt-plasma> * jt-plasma goes back to the wiring diagram
[18:02:14] <danimal_garage> jt-plasma: sent. and yes i know i need to tidy it up a bit :)
[18:02:29] <soapy> anyone know why I'm getting errors when I try to run anything, that say "all joints must be homed before going itno coordinated mode"?
[18:02:35] <danimal_garage> whats your issues soapy?
[18:02:42] <jt-plasma> thanks danimal_garage
[18:03:08] <jt-plasma> soapy: you have to home the all the axis before moving
[18:03:11] <soapy> I can get gcode to run, but only if I load the file after restarting EMC2, then I have to home the 3 axes stragith away
[18:03:13] <danimal_garage> soapy: you really should home it before doing anything
[18:03:49] <danimal_garage> you have to home each axis before you run anything in mdi or run a program
[18:03:49] <soapy> if I do anything else, I can't get it to run, even though I've manually homed all 3 axes and the home symbol is showing on all 3 readouts
[18:04:14] <danimal_garage> so it is homed and it still wont work?
[18:04:28] <soapy> ok, but why then does it not work after I've homed the axes and then change, say, the feed rate?
[18:04:39] <soapy> yes, it only works if I home then press play
[18:04:51] <soapy> anything else, it complains it isn't homed, even after homing
[18:05:04] <danimal_garage> hmm
[18:05:11] <jt-plasma> double hmm
[18:05:11] <MrSunshine_> lol this is redicoulus or however its spelled
[18:05:26] <danimal_garage> thats a bit out of my league
[18:05:28] <MrSunshine_> trying to amke toolpaths for an image with image-to-gcode that comes with emc ... it has been working for 8 hours now
[18:05:30] <MrSunshine_> still not done
[18:05:38] <soapy> I've been restarting EMC2 each time, to run anything, and it's getting annoying
[18:05:52] <MrSunshine_> or i have a to big picture or to small steps or something
[18:06:07] <soapy> especially since I spent most of the day working out I have to swap to "world" to get both my X axes to drive
[18:06:16] <jt-plasma> soapy: each time you restart EMC you must home unless you put NO_FORCE_HOMING in the ini file
[18:06:27] <soapy> thanks, I'll go and add that
[18:06:40] <jt-plasma> check the integrators manual for that
[18:06:47] <soapy> nopefully then it will shut up with the errors and let me do anything!
[18:06:57] <jt-plasma> http://www.linuxcnc.org/docview/html//config_ini_config.html#sub:[TRAJ]-section
[18:07:25] <danimal_garage> i'm excited now that i have some experience with ladder
[18:07:35] <danimal_garage> now i think i can tackle my mill's ATC
[18:08:43] <danimal_garage> i think this toolchanger is unchartered territory for EMC
[18:18:56] <soapy> thanks, overriding the NO_FORCE_HOMING = 1 gets me past that hurdle
[18:20:07] <soapy> now I'm getting "Exceeded soft limit" when I swap into World mode
[18:20:43] <soapy> I've zeroed it (homed it) to the right place, and the override lets me carry on without that bug
[18:22:26] <soapy> for some reason, when I change to "world" the X jumps from 0.0000 to -3.57 and I get the "exceeded sfot limit" thing
[18:22:30] <danimal_garage> you can set your soft limits in the ini
[18:23:25] <danimal_garage> if you're not going to actually home your machine to a specific spot, you can just make your soft limits like 100 inches or something
[18:23:30] <soapy> I don't understand, though - the machine is in the right place, and I start EMC2. It reads the soft limits from the file, and then tells me the machine is in the wrong place? is that right?
[18:23:34] <jthornton> soapy: what do you mean you changed to "world"?
[18:23:48] <soapy> jthorton, in the "veiw"
[18:23:52] <jthornton> if you have an offset it is
[18:23:59] <cradek> "This error indicates that either a limit switch has been opened or the FMDC board has opened CR1 or the spindle motor overload has opened or E stop button is pressed"
[18:24:06] <soapy> I have two steppers on the X drive, one either side
[18:24:21] <soapy> unless I swap to "world" from "joint" then jog only drives one of them
[18:24:23] <cradek> (grr)
[18:24:57] <skunkworks_> woo hoo - the nut came off!
[18:24:59] <soapy> cradek, where is there a list of what the error codes and statements mean? That would probably be a great help
[18:25:21] <danimal_garage> skunkworks: sounds painful
[18:26:26] <skunkworks_> heh
[18:26:32] <soapy> danimal, is there a way to tell the software to simply home to a point, rather than setting where it is as the new home?
[18:26:48] <soapy> skunk, I take it that's what you wanted to happen?
[18:27:17] <skunkworks_> yes - it is a nut that sets the preload to about 6 gears. (grinding the washer between 2 gears)
[18:27:47] <jthornton> * jthornton can't seem to find the world/joint button
[18:28:11] <soapy> jthorton, go to the menu, click "veiw" then it's the last two items
[18:28:16] <soapy> or toggle with $
[18:28:25] <danimal_garage> soapy, yes, but you need home switches
[18:28:40] <soapy> d, ok, thanks
[18:29:03] <jthornton> 2.3.x?
[18:30:34] <soapy> 2.3.0
[18:30:47] <soapy> according to the header of the window, anyway
[18:31:56] <jthornton> in AXIS? or another interface?
[18:35:27] <soapy> in AXIS
[18:35:42] <jthornton> what kind of machine?
[18:35:44] <soapy> anyway, by simply restarting EMC for the 200th time, I've got it to work
[18:36:03] <soapy> it's a 3 axis machine
[18:36:13] <soapy> www.lumenlab.com
[18:36:38] <soapy> got it yesterday, and have spent the day messing about to get it working
[18:37:01] <jthornton> cool
[18:37:17] <soapy> I've just got it to draw the EMC2 AXIS "logo" that comes up when you start the program, in pencil :-D
[18:37:53] <soapy> had to slow it down to 33IPM on the slider first, though, and do that override thing, and suss out the "world" thing
[18:38:16] <soapy> j, if you go into EMC2, there are three menu items, right?
[18:38:39] <soapy> click on "Viewe", the third one, and at the bottom it should say "Joint" and "World"
[18:39:12] <jthornton> all of mine have show machine position, show commanded position
[18:39:19] <soapy> interesting
[18:39:25] <soapy> what version are you running?
[18:39:36] <jthornton> very interesting, all of them
[18:39:41] <soapy> perhaps I need to update mine to the newest version
[18:40:09] <jthornton> if your running 2.3.0 yes you should update
[18:40:25] <soapy> I'll sort that out in a bit, when I wire the machine to the lan
[18:40:49] <soapy> I see 2.3.4 is the newest version
[18:41:04] <soapy> anyway, thanks, all, for the help, I was tearing my hair out!
[18:41:10] <jthornton> np
[18:41:21] <soapy> going to go show off the nice pencil drawing I just did

[21:06:19] <archivist_emc> no
[21:06:32] <archivist_emc> just us bots
[21:06:54] <Tankenator> lol
[21:07:19] <Tankenator> im having trouble tryin out emc
[21:07:27] <Tankenator> wondering if anyone could help
[21:07:44] <Tankenator> i dont have a machine, although i am a machinist, and would love to just play with the software
[21:08:14] <Tankenator> currently run linux on laptop (i know about the latency issues of laptop, this wouldnt matter as it would be simulated)
[21:08:21] <Tankenator> running ubuntu 9.10
[21:08:33] <Tankenator> trying to follwo the directions to just install simulator
[21:08:41] <Tankenator> and run into tkinter issues
[21:09:12] <Tankenator> it wont compile
[21:09:30] <Jymmm> You could just download and burn the LiveCD
[21:09:36] <Tankenator> ya
[21:09:39] <Tankenator> working on that
[21:09:56] <Tankenator> but i dont want to hose my instal for that, was thinkin of using it in virtulabox
[21:09:59] <Tankenator> would that work?
[21:10:25] <Jymmm> check MD5 and burn at slower speeds of the LiveCD
[21:10:43] <Tankenator> i know how to do the livecd etc
[21:11:08] <Jymmm> 9.01 isn't supported.
[21:11:21] <Tankenator> i know, unfortuantly
[21:11:35] <Tankenator> was trying to compile according to the instructions for it
[21:11:35] <Jymmm> livecd has simulator, which can run under a VM
[21:11:39] <Tankenator> e.g.
[21:11:40] <Tankenator> ok
[21:11:49] <Tankenator> so it wont puke in a vm
[21:11:52] <Tankenator> that should do me
[21:11:53] <Tankenator> :D
[21:12:36] <Tankenator> a version gonna work with 10.04?
[21:45:06] <mozmck> Tankenator: there are karmic packages on experimental you could try...
[21:46:09] <Skullworks> JMK - is there a link to the design you used for your Shoptask Mill ballscrew conversion?

[22:42:45] <mozmck> hmm, is there a way to have AXIS load the last file used? or even just change which file is loaded?
[22:42:56] <mozmck> I'm using emc2 2.3.1
