[00:01:01] <KimK> IF EMC2 is running in step/dir mode, you are running open loop. Unless you are planning to run step/dir in closed loop mode. There are people who have claimed to make it work, but I've never seen a demo.
[00:01:39] <nicko> ahhh
[00:01:43] <nicko> this is the issie
[00:02:13] <nicko> issue - I thought, you could or at least should have been given it as an option
[00:02:28] <nicko> this isn't out of being technically wise to this stuff - its out of ignorance
[00:02:30] <KimK> Plus it's probably not necessary, your Allen-B drives probably have analog +10V/-10V control inputs already.
[00:02:38] <nicko> yes they do -
[00:02:48] <nicko> but I've run out of channels
[00:02:54] <nicko> I need another 7i33
[00:03:21] -!- theorb [theorb!~theorb@91.84.53.6] has joined #emc
[00:03:43] <nicko> I think I have a work around anyway - the XY & Z drives can take PWM directly - unlike the allen bradley - soI just have to jiggle it about a bit
[00:04:00] <KimK> Oh, yes, I see. Or maybe (if you're short on ports) sell your 7i33 and get one of the higher order cards, maybe a 6-input?
[00:04:21] -!- theorbtwo has quit [Ping timeout: 264 seconds]
[00:04:26] theorb is now known as theorbtwo
[00:04:27] <nicko> I'm going for 2x 7i33 - as I might with other projects go up to 8 axes ...
[00:05:06] <nicko> I just got one so in the case it all turned to poo, I wouldn't have spent more than I needed to in the meantime - but as it turns out (hindsight!) it has ben a hassle
[00:05:17] <KimK> OH, OK. They do have an 8 axis, but it's a lot more money than 2x 7i33, so yoou really have to want to save a port.
[00:05:28] <nicko> no need
[00:05:35] <nicko> the 5i22 is ample
[00:05:56] -!- OoBIGeye has quit [Ping timeout: 260 seconds]
[00:06:01] <nicko> (thanks for your help by the way)
[00:06:08] <KimK> Yes, you might want to add a handwheel, or some other quadrature thing. Ah, I have the 5i22 also. Small or large?
[00:06:39] <nicko> large - ordered small, but they only had large so I got the 0.5 gratis
[00:06:54] <nicko> yes handwheels - x 2
[00:07:06] <nicko> in the future that is
[00:07:21] <nicko> th rest can be done by jogging
[00:07:33] <nicko> one input only I think yeh ?
[00:07:33] <KimK> Ah, excellent. I'm using the -1.5 too.
[00:07:55] <nicko> have you ever set up your own stuff using softDMC ?
[00:08:12] <nicko> or the LEDS - ever used them ?
[00:08:45] <nicko> pncconf as I understand it wont let you fiddle with them
[00:10:05] <KimK> SoftDMC, that's Mesa's own motion software, right? No, I've never done anything with that. The LEDs are not really visible in my case, it's too low to see. I was thinking about adding a piece of plexiglas/perspex so I can see the lights at the top edge better.
[00:10:34] <KimK> s/in my case/in my computer case/
[00:10:35] <nicko> use fibre optic cable
[00:11:26] <KimK> Ha, that too. Find one of those lamps that were in fashion for awhile.
[00:11:34] -!- robh__ has quit [Ping timeout: 258 seconds]
[00:11:42] <nicko> its pretty effective - shoveit up against them (make a fancy bracket) same a the other end, the distance away from some diffuse transparant material = size and intensity
[00:11:45] -!- OoBIGeye [OoBIGeye!~kent@81-231-97-123-no48.tbcn.telia.com] has joined #emc
[00:11:48] <nicko> ok
[00:12:07] <nicko> so heres my error - I want to use the spindle speed .hal program
[00:12:30] <nicko> whenever I select it in pncconf its fune untill I open EMC:
[00:13:19] <nicko> 'addf requires at least 2 args, 1 given'
[00:13:26] <nicko> the line in question is:
[00:13:42] <nicko> 'addf servo-thread'
[00:14:13] <nicko> no idea what the other arg is meant to be
[00:15:01] <KimK> "addf" Means add a function to a thread. So we need to know, what thread (you said the servo thread, good) and what function (you didn't say) so addf doesn't know what to do.
[00:16:09] <KimK> addf servo-thread pid.6.something-or-other?
[00:16:22] <nicko> right, well its from pncconfso maybe I'll just delete the line and see ...
[00:16:59] <nicko> the previous lines are:
[00:17:15] <nicko> addf abs.spindle servo-thread
[00:17:26] <nicko> addf scale.spindle servo-thread
[00:17:38] <nicko> addf lowpass.spindle servo-thread
[00:18:03] -!- krushia [krushia!~krushia@h69-131-92-179.cntcnh.dsl.dynamic.tds.net] has joined #emc
[00:18:08] <nicko> I wonder if there is meant to be something, or the whole line is not meant to be there
[00:18:34] <nicko> hmmmm
[00:18:38] <nicko> opens without it
[00:18:54] <nicko> heh heh - I wonder if it'll bite me in the bum
[00:18:59] -!- nicko has quit [Quit: Visitor from www.linuxcnc.org]
[00:19:28] <KimK> OK, so you added an absolute value function, a scale function, and a lowpass function. You just need to look at (or make) a diagram of how this stuff all connects together.
[00:20:03] <KimK> And all the functions you added were named "spindle"
[00:20:41] -!- L84Supper has quit [Ping timeout: 240 seconds]
[00:21:19] <KimK> So now if you try to do "addf abs.spindle servo-thread" again, you'll have to use a new name, spindle2 maybe?
[00:23:12] <KimK> The other way is just to use numbers: axis.0, axis.1, etc. But there's nothing stopping you from saying axis.left-right, axis.in-out, axis.up-down, etc.
[00:23:55] <KimK> OK, maybe axis was abad example, I don't know if that's a re-nameable HAL component, but you get the idea.
[00:26:34] <KimK> And with that, I'd better be going, I have to go move some things. But I'll be back later. Come back with more questions anytime.

[00:33:35] <nicko> Heres another newbie question
[00:34:02] -!- moopy has quit [Ping timeout: 276 seconds]
[00:34:32] <nicko> inputs - I have set up a 5i22 pin as an input to test, its function is 'allhome' - I see that the pin is at 3.3v
[00:35:01] <nicko> I was expecting it to be at 0v and I would give it logic high to activate the 'allhome' function
[00:35:10] <nicko> not sure what to do here
[00:35:19] <nicko> am I meant to connect it to ground ?
[00:35:35] <nicko> (which hasn't done anything)

[00:45:39] <Tom_itx> set it up as .in_not
[00:54:44] <nicko> invert it ?
[00:54:47] <nicko> okidoke
[00:55:19] <nicko> how is one meant to toggle pins with it in the current state it is in ?
[01:02:13] <Tom_itx> i set my pendant up similar. i still take the inputs high to toggle them
[01:02:43] <nicko> Could anyone provide me with the G-code to start a spindle and have it just sit there untill I switch it off manually ?
[01:02:55] <nicko> I have s60 M3 so far
[01:02:57] <Tom_itx> M3
[01:03:14] <Tom_itx> you may need to specify a tool
[01:03:28] <nicko> Where can I type this in directly into EMC ?
[01:03:35] <nicko> or do I have to write a file ?
[01:03:40] <Tom_itx> in the MDI window
[01:03:41] <Tom_itx> i think
[01:04:13] <nicko> oh dear
[01:04:19] <nicko> right there under my nose
[01:04:21] <nicko> thanks!
[01:10:33] <Tom_itx> i've found that i have had to invert nearly all my gpio

[16:29:37] <willburrrr2003> Someone on here was talking about using the g83 peck drill cycle for parting off on a lathe setup, so I am trying to figure out the g83 format to do this, can someone please explain the way g83 works with emc?
[16:32:50] <awallin> http://www.linuxcnc.org/docs/2.4/html/gcode_mill_canned.html#r1_5
[16:35:20] <jthornton> why would you want to use g83 for parting off?
[16:36:09] <awallin> part-off does generate lots and lots of heat I find... broke some hss blades when practicing :)
[16:37:22] <willburrrr2003> I have read the g83 description, but it gives no example how to use it? I am having major troubles parting off...lots of chattering, no strings peeling off just little chips, and if I feed to fast I stall the spindle
[16:38:23] <willburrrr2003> was told that peck drilling cycle would help with parting off until I can use FPR and CSS to get a smooth cutting action
[16:39:02] <awallin> are you using flood-coolant? lots of it!
[16:39:23] <willburrrr2003> I don't have flood coolant, am using oil bottle
[16:39:44] <jthornton> chattering means you have slop somewhere and the workpiece is climbing up on the parting tool, no software can fix that
[16:40:36] <awallin> I haven't worked a cnc-lathe, but I think one trick is to not have the sides of the tool rub against the part. somehow most of the slot needs to be wider than the part-off blade so you don't get heat and uncontrollable heat-buildup
[16:41:28] <willburrrr2003> jthornton: I was thinking that a couple days ago, but haven't been able to find it....I may have to do a complete teardown and start putting the carriage and cross-slide back together from beginning....
[16:42:19] <willburrrr2003> awallin: the shape of the blade does what your talking about
[16:42:54] -!- El_Matarife has quit [Quit: Nettalk6 - www.ntalk.de]
[16:43:14] <jthornton> well alignment of the blade perpendicular to the workpiece is important
[16:43:32] <awallin> willburrrr2003: right... I've seen some videos where the blade goes in at slightly different z-positions in the beginning. presumably to create a wider slot
[16:43:57] <jthornton> willburrrr2003: put a dial indicator on the part to see if your head stock is loose when you part off
[16:45:22] <willburrrr2003> alignment is indeed improtant, I have made sure of alignment very carefully. I like the idea of the doal indicator...should I put it on top to part or behind it?
[16:46:46] <willburrrr2003> awallin, seems to depend on the parting blade for that, in general should not have to do it though... cutting tip of blade (top) is wider than any point below it, so that only cutting edge touches sides of cut ....this reduces the drag and friction of the cutting process
[16:47:03] <jthornton> I would put it top back middle, I don't think it will matter if it is loose it will jump a lot. without running try and move the material by hand with the dial indicator to check
[16:47:15] <willburrrr2003> at least thats what I have gotten from trying to learn about parting so that I can fix my issue
[16:47:25] <archivist_emc> dti on to of the chuck ref to bed and lift, does it move
[16:47:32] <jthornton> then put the dial indicator on the tool and try and move it
[16:47:35] <archivist_emc> to/top
[16:47:58] <willburrrr2003> and all this without running, correct?
[16:48:16] <jthornton> yea
[16:48:23] <archivist_emc> iirc this lathe has a heavy chuck for the spindle size
[16:48:35] <archivist_emc> lots of overhang
[16:50:04] <willburrrr2003> gonna head out to shop, and check with indicator. I'll let you guys know in a couple mins what I see, thanks for the tips

[19:24:00] <KimK> skunkworks: That's why I thought it looked interesting. And it would be controlling two axes instead of just one. Something like sin of C angle controlling Y, and cos of C angle controlling X. Though I confess I haven't thought about it too much. And mrsunshine is right, the tool length offset would be in there too. I wonder if you could make it so you could turn it on and off in HAL, so you only need one set of ini/hal files?

[19:25:50] <mrsunshine> KimK, what? :P
[19:25:53] <mrsunshine> what have i said? :P
[19:27:10] <KimK> mrsunshine: Oh, sorry, duly noted. Your tool offset remarks pertain only to your tool offset remarks, lol. Skunkworks and I need some tool offsetting too!
[19:27:26] <mrsunshine> heh =)
[19:27:39] <mrsunshine> im trying to figure out gcode and handwrite gcode for a piece with a hole in it :P
[19:27:41] <mrsunshine> with 3 tools =)
[19:28:00] <KimK> Need some help, of have you got it handled?
[19:28:06] <KimK> s/of/or/
[19:28:07] <mrsunshine> and i dont get it why in examples it uses G43 to use the tool table offset then specifies H3 that aprently also is a offset?
[19:28:54] <KimK> Is that in the docs? Where are you reading that? (I'm trying to clarify the docs right now.)
[19:29:11] <KimK> Online or PDF?
[19:29:15] <mrsunshine> ohh, G43 H3 aparently means to turn on tool length compensation of tool 3
[19:29:29] <Tom_itx> yep
[19:29:38] <Tom_itx> or any other for that matter
[19:29:41] <KimK> Yes, you can specify a particular table entry if you wish.
[19:30:02] <mrsunshine> but if i omit the H3 for example, it will still use the default tool length offset of T3 ?
[19:30:11] <Tom_itx> nope
[19:30:19] <mrsunshine> i thgouth G43 was for that =)
[19:30:29] <Tom_itx> G43 is an on off switch
[19:30:37] <Tom_itx> H holds an offset value
[19:31:10] <mrsunshine> oki, gonna read some more on it, found a tool length tutorial =)
[19:31:12] <mrsunshine> thanks =)
[19:31:44] <Tom_itx> G49 cancels it
[19:32:22] <KimK> Picking a specific table entry is particularly useful when a tool can have two lengths. Like a slitting saw, where in one situation you're leaving the good material below the saw, and in another situation you're leaving good material above the saw.
[19:33:24] <Tom_itx> soooo confoosing
[19:34:17] <KimK> I'll make a note to discuss this point in the next docs upgrade.
[19:34:37] <Tom_itx> i didn't notice the H word in the docs
[19:34:43] <Tom_itx> but i may have overlooked it too
[19:34:54] <Tom_itx> other than at the G43 command

[19:58:39] <mrsunshine> ffs, i hate this, why cant people just settle for one freakin standard on how to write gcode for example
[19:58:52] <KimK> Tom_itx: I was just scrolling back. Do you mind if I edit one of your recent lines? "G43 is an on off switch". I would offer instead "G43 is an on switch". That works better with your "G49 cancels it", which is correct. (Gaah! It's becoming a problem now. I can't stop editing!)

[20:02:24] <Tom_itx> KimK, i agree with that
[20:02:44] <Tom_itx> maybe 'part of an on off switch' would be a better analogy
[20:03:39] <mrsunshine> is the M words programmable in emc ?
[20:03:43] <mrsunshine> or other machines also
[20:03:54] <Tom_itx> i think they are
[20:04:01] <mrsunshine> im thinking if i make myself a tool changer, can i script what heppends when a M6 T3 is issued ?
[20:04:07] <KimK> EMC2 offers user-programmable M100-M199
[20:04:46] <KimK> Oh, that's different. Sure, either in HAL or by ladder, maybe other ways too. Gcode?
[20:04:55] <Tom_itx> mrsunshine, do you need a prefetch on a tool change?
[20:04:59] <JT-Shop> you can make a comp too
[20:05:00] <Tom_itx> alot of machines do a prefetch
[20:05:40] <mrsunshine> Tom_itx, i dont know at all how it works, just wondering =)

[20:05:43] <mrsunshine> was a thought that struck me :P
[20:06:07] <JT-Shop> good, I got my motherboard changed here and it is time to go cook 60lbs of crawfish
[20:06:33] <KimK> JT-Shop: Now you're talking! I'll be right there!
[20:06:36] <JT-Shop> and the friggin heat index is 103F
[20:06:39] <KimK> Hahaha
[20:06:47] <skunkworks> yeck
[20:06:47] <Tom_itx> JT-Shop, humid/
[20:06:48] <Tom_itx> ?
[20:07:07] <JT-Shop> not really it is just 61% which is low for us
[20:07:16] <mrsunshine> the spidnle is stopped at M6, but will not be turned on again until i call a M3 on it again ? :)
[20:08:03] <KimK> JT-Shop: Heard some Missouri levees are leaking, hope that's far away from you?
[20:09:18] <JT-Shop> well they always leak down hill so I'm safe
[20:11:07] <KimK> mrsunshine: Yes, an M6 should (must!) stop the spindle, but "elegant programming" doesn't rely on that. Use an M5 to show what you mean. And yes, either way you need a new M3.
[20:12:41] <KimK> Things get kind of scary otherwise, if the spindle comes screaming out of the tool change "unbidden".
[20:14:38] <mrsunshine> hmm, so now im at the point of profiling the outside of the part, after i have drilled a hole, its a repetetive thing, is there a way to loop that works on all systems or is it controller etc specefic?

[23:49:02] <Tom_L> i could put it out the top
[23:49:40] <andypugh> There are small e-stop buttons. I have never found a source, but they get fitted to our test cars.

[23:49:56] <Tom_L> that's the one i'm measuring off of
[23:50:16] <andypugh> Ah, yes, probably no smaller than that.
[23:50:36] <andypugh> You can bend the terminals flat..
[23:50:37] <Tom_L> i think the model just makes it look big
[23:51:06] <andypugh> A huge e-stop is fairly typical anyway.
[23:51:33] <Tom_L> i would be less likely to bump it on something on the top i think

[23:52:13] <andypugh> Has it out the side
[23:52:31] <Tom_L> yeah

[23:53:18] <Tom_L> i sorta used that as a starting point
[23:53:48] <andypugh> I am happy with my gamepad, to be honest
[23:53:52] <Tom_L> maybe i should step the whole lid
[23:54:20] <Tom_L> i'm tryin to brush up on my cad anyway
[23:54:25] <Tom_L> been a while
[23:55:04] <andypugh> Well, one big thing with my gamepad is where to park it. If you had an integral hook in the back, you might be able to squeeze the e-stop base into that.

[23:56:15] <andypugh> I am guessing that Bluetooth doesn't make the grad for e-stop function.
[23:56:27] <Tom_L> no
[23:56:34] <Tom_L> you want a hardwire
[23:56:41] <andypugh> I think I forgot a smiley
