Back
[00:01:25] <andypugh> I don't see the point of that mill, but it's a nice bit of work.
[00:02:02] <andypugh> I can imagine something similatr being a good technology deomostrator for a controller manufacturer.

[00:06:53] <Tom_itx> andypugh, i'd never used the lathe cam so it was in rough shape
[00:07:14] <Tom_itx> and i threw the post together after you asked for help
[00:07:23] <Tom_itx> so i knew it was in need of a bit of work
[00:08:12] <Tom_itx> i could have posted the G0 on separate lines as you did but i didn't know it needed it
[00:08:20] <Tom_itx> not all controls behave the same
[00:08:46] <Tom_itx> your feedback would help me get a good working post

[00:09:17] <t12> jymmm: san francisco
[00:09:41] <Tom_itx> andypugh, did you do the z move first then x?
[00:09:51] <Tom_itx> on the rapids
[00:10:15] <andypugh> No, X then Z.
[00:10:27] <Tom_itx> i'd like to repost it and have you at least load it
[00:10:34] <Tom_itx> even if you don't use it
[00:10:49] <andypugh> A small Z move away from the work, then the X then the Z would be even better.
[00:11:15] <Tom_itx> that's what the 20mm retract was supposed to do but i'm not sure it was doing it
[00:11:32] <Tom_itx> i need to read a bit more about the lathe package to figure out how that is handled
[00:12:22] -!- tjb1 [[email protected]] has joined #linuxcnc
[00:13:16] <andypugh> 20mm retract is unusally much. I typiclally retraco 0.2mm :-)
[00:13:21] <Tom_itx> i think i can add it as soon as i figure out what variable it uses in the post
[00:13:34] <Tom_itx> i know, but i wanted to be sure it was working
[00:13:42] <Tom_itx> i normally don't retract that much either
[00:14:01] <Tom_itx> just enough to clear the tool tip and any fixtures
[00:14:15] <andypugh> I wonder why that portable-cnc chap messes about with Kflop? Has he never heard of LinuxCNC?

[00:14:23] <Tom_itx> you gonna be around a while?
[00:14:27] <Tom_itx> i'm gonna shower
[00:14:40] <andypugh> No, it's time I logged off to sleep.
[00:14:58] <Tom_itx> well i'll mess with it and maybe have something to try in a day or so
[00:15:06] <andypugh> I'll be back tomorrow though. I have the plywood blanks glued up in the garage.
[00:15:14] <Tom_itx> i'd like to get a working post for lcnc
[00:15:21] -!- R2E4_awy2 [[email protected]] has joined #linuxcnc
[00:15:38] <Tom_itx> for the lathe...
[00:15:42] <Tom_itx> i have one for the mill
[00:16:26] <Tom_itx> there are all sorts of template words i can use but the template was a very basic one i started with
[00:16:45] <Tom_itx> i imagine the z retract was one not used in this one
[00:18:19] <Tom_itx> the whole template is only about 35 lines
[00:20:07] <andypugh> What software are you using?
[00:20:12] <Tom_itx> smartcam
[00:20:16] <Tom_itx> an old version
[00:20:25] <Tom_itx> it's quite similar to mastercam

[00:22:04] <andypugh> Looking at it now.
[00:22:22] <Tom_itx> mine is probably 15yrs old
[00:22:48] <Tom_itx> i didn't keep the license up on it since they switched over to Catia in the shop
[00:23:05] <Tom_itx> so i use it for my hobbies now

[00:24:36] <JT-Shop> Tom_itx: we are fixing to get wet
[00:24:48] <Tom_itx> we are already wet
[00:25:04] <Jymmm> JT-Shop: the good wet or the you've been very bad wet?
[00:25:08] <JT-Shop> check this out http://www.linuxcnc.org/index.php/english/forum/40-subroutines-and-ngcgui/26221-qteardropq-subroutineq#30583
[00:25:09] <Tom_itx> we didn't get what they predicted though
[00:25:22] <JT-Shop> Jymmm: dunno
[00:26:31] <Tom_itx> andypugh, i have the freeform mill and basic turn package
[00:26:45] <JT-Shop> I usually loose sat connection when the rain starts :(
[00:27:01] <Tom_itx> better say it all now then
[00:27:06] <Jymmm> JT-Shop: thats just a WX indicator
[00:28:11] <JT-Shop> if you want to stick a few of them doo-dads in an envelope and mail them to me I can try and glue them

[00:29:44] <Tom_itx> is that closer to what you did?
[00:29:57] <t12> dang i didnt realize

[00:31:17] <Tom_itx> andypugh, the retracts are still broke in those
[00:31:22] <Tom_itx> need to read a bit on that first
[00:32:20] <andypugh> That's pretty much it, yes.
[00:32:28] <Tom_itx> that was an easy fix
[00:32:49] <Tom_itx> now i'll figure out the retract and add that in after bit
[00:33:09] <andypugh> Something funny at 2654 too. (I changed the order of some operations in my meddled-with version.)
[00:33:11] <Tom_itx> i reposted both files in case you hadn't edited the other one
[00:33:51] <Valen> andypugh: oh god, i used usps as an example of a postal carrier when talking to dmm
[00:34:07] <Valen> so they gave me a price on driving to USA and posting it
[00:34:14] <andypugh> "Lose an elephant, break an anvil"?
[00:34:36] <Valen> i did say "eg usps or canada post"
[00:34:56] <Valen> I sent him a link to canadaposts parcel calculator
[00:35:10] <andypugh> I bet there are boats from Vancouver to Aus.
[00:35:26] <Tom_itx> andypugh, i'll probably post another fix by tomorrow for the z retract
[00:35:28] <Tom_itx> showertime now
[00:35:35] <toastyde1th> off topic, is anyone excited about the ubuntu phone os
[00:35:41] <andypugh> Yeah, I said I was logging 20 mins ago

[01:39:14] <skunkworks> there are quite a few people that have gantry machines.. I think they all do if different... ;)
[01:41:14] <skunkworks> gantry kins has some drawbacks I think. (like you have to switch from joint to world mode..)

[01:49:05] -!- Valen has quit [Read error: No route to host]
[01:50:03] <R2E4> Thats a nice machine. Problem with it is the angle iron the vbearings are on wears out and if you dont use it the same all the way accross the axis it wears differently and you end up with a very inaccurate machine.

[02:24:20] <skunkworks> I have a few 10tb raid boxes (pretty inexpensive)
[02:24:43] <Jymmm> which?
[02:25:14] <skunkworks> they work great for what we need. I did have to update the firmware in all of the (again inexpensive) esata controlers we had. The would randomly drop drives. (I have not had an issue since)
[02:25:25] <Valen> nasty bug
[02:26:16] <skunkworks> they would go for weeks and then a drive would drop

[02:26:24] -!- minibnz [[email protected]] has joined #linuxcnc
[02:26:48] <skunkworks> My helper looked today - one of the server has been up for almost a year. (gasp - 12.04)
[02:28:09] <minibnz> does anyone here know how well a 808nm laser will go for cutting plastic and steel? the one unit i have here for testing is 1watt (i know its a baby) once i have my thoery right i will purchase a 50watt laser diode..
[02:28:47] <Valen> mind yer eye safety, even with the 1W
[02:29:05] <Jymmm> 50W YaG will cut steel
[02:29:07] <Valen> I *think* the IR will be ok in plastic but probably not steel
[02:29:11] <Jymmm> not a CO2
[02:29:13] <Valen> its pretty reflective
[02:29:40] <r00t4rd3d> i have some 5mw lasers and they blind me
[02:29:43] <minibnz> ahh i have goggles on their way :)
[02:30:03] <t12> and i think the 50W units
[02:30:06] <t12> are gonna have really weird beams
[02:30:11] <Valen> don't use it till you have them
[02:30:12] <minibnz> jymm i am thinking of a solid state diode. rather than a YAG setup.
[02:30:12] <t12> like its going to be a big oval
[02:30:29] <Jymmm> minibnz: then think 2000W
[02:30:33] <Valen> IR reflects of odd things and can bounce quite a ways
[02:30:34] <t12> theres special lenses for handling them
[02:30:52] <Jymmm> 2000W CO2 or 50W Yag for metals.
[02:31:04] <minibnz> tl2 the 50watt diode is a single bar unit. 10mm wide, yes they will need optics to clean up.
[02:31:27] <Valen> perhaps just get a fiber coupled one and don't bother ;->
[02:31:42] <Valen> I saw some 20W modules on the ebays a while ago, havent seen any since though
[02:31:53] <minibnz> valen i was thinking the same but they are beyone DIY.. and will cost mega $$$$
[02:32:09] <Valen> probably
[02:32:10] <minibnz> valen i have found 50watt diodes on ebay for 100$us
[02:32:26] <Valen> I was just going to stick a CO2 tube on the side of the head on the mill ;->
[02:32:48] <Tom_itx> does lcnc ignore text after the ';' ?
[02:32:58] <Tom_itx> so i can insert comments in gcode
[02:33:44] <skunkworks> Jymmm: rosewill 8 bay esata boxes
[02:33:45] <minibnz> valen i thought the same thing but when you get to about 400watts with a co2 laser tube they get a bit LARGE...
[02:34:04] <Valen> heh just a touch
[02:34:38] <minibnz> i was looking on youtube the other day and a 4kw laser tube is about 10inches round and 9feet long...
[02:34:39] <skunkworks> using some relativity cheap rocketraid pcie esata cards
[02:36:41] <Jymmm> ew
[02:37:41] <r00t4rd3d> when i eat mcdonalds my farts reek
[02:38:21] <r00t4rd3d> the dog left the room :/
[02:39:15] <minibnz> hehehe nice.. if you can get the dog to clear out you should probably steer clear of maccas..
[02:39:36] <Valen> I once had to leave outside and go back inside it was so bad

[02:40:07] <minibnz> sorry.. Aussie slang for mcdonalds...
[02:40:17] <r00t4rd3d> i thought it meant church
[02:40:21] <R2E4> You guys kn anyone making 4th axis servo units?
[02:40:24] <Jymmm> McD's Steak House

[02:40:29] <Valen> sydney here
[02:40:41] <Jymmm> Mickey D's
[02:40:45] <r00t4rd3d> AYE MATE!
[02:40:53] <Valen> mcchuckers here
[02:40:55] <FinboySlick> Actually, McDonalds often has region-adapted menus. You can get poutine here in Quebec.
[02:40:55] <minibnz> Valen yeah me too..
[02:41:10] <Jymmm> r00t4rd3d: go light a bon fire =)
[02:41:10] <FinboySlick> What do aussies get, McVeggimite Burgers?
[02:41:14] <Valen> nifty lol, penrith/mountains here
[02:41:15] <Jymmm> lol
[02:41:18] <r00t4rd3d> is there a mcdonalds in mcchuckers?
[02:41:42] <minibnz> finboyslick they do that here in AU we have lamb burgers :) now they are great...
[02:41:43] <Valen> we called it mcchuckers because my younger brother would always eat until he puked when we went there
[02:41:52] <Valen> those are friggin briliant
[02:42:05] <Valen> 5000+kj in one burger but still
[02:42:14] <r00t4rd3d> the uk just tried horse burgers, didnt work out.
[02:42:17] * FinboySlick was once brought me vegimite on his trip to Canada... He was disappointed by my assessment of the taste.
[02:42:21] <minibnz> heheheh
[02:42:46] <Valen> (5000kg =~ half the RDI lol)
[02:43:10] <FinboySlick> We put cretons on toast here. It's like vegimite, but it's made with pork.
[02:43:32] <Valen> minibnz: what you doing anyway?
[02:43:47] <minibnz> hmm interesting.. vegemite is made from the left overs from brewing beer...
[02:44:00] <Valen> I prefer promite my self
[02:44:17] <Valen> vegemite you need to put a teensy amount on, promite you can put on by the inch
[02:44:48] <FinboySlick> Well cretons is from brewing pork!
[02:45:09] <minibnz> Valen i just put together a CNC mill out of a sieg X2.... I built a dividing head for it.. added steppers to all the axis' and now looking for a pneumatic cylinder to mak a toolchanger...
[02:45:30] <FinboySlick> minibnz: Very industrious.
[02:45:35] <minibnz> Valen yeah vegemite should only be applied just enough to change the color of the toast..
[02:45:37] <Valen> toolchanger nice
[02:45:52] <Valen> we would really like one for our hm45 conversion
[02:45:52] <minibnz> finboyslick i bought the mill to make a part for my 3d printer..
[02:45:56] <r00t4rd3d> I was looking up some Australian slang. Bumtoucher - a man who touches rectums.
[02:46:13] <Valen> then realised that the mill is far better than 3d printing? ;->
[02:46:39] <Valen> r00t4rd3d: you talkin about hopo
[02:48:26] <minibnz> heheh yeah i started out building the printer, got to the point where i designed and made a 3 filament extruder but the hobbed bolt was not good enough, and had to cut a gear like bolt, Known as a hyena (arcol tm) i needed one with three drive sections. so i bought the minimill (i call it the milliscule - a miniscule mill ) then i build the dividing head to make the drive bolt i needed..
[02:49:01] <minibnz> now i am looking to see what other things i can either add to them or add to the workshop, and lasers are cool..
[02:49:43] <FinboySlick> Remember, don't look at laser with remaining eye.
[02:50:23] <minibnz> looking at ebay makes me wonder where all the $$$$$ go into the comercail units.. as i can get a 400watt diode for $700 delivered. the hard part (as far as i can see) is the optics, but even the parts for that are cheap..
[02:50:45] <minibnz> so i am contemplating building a full sheet laser cutter..
[02:51:02] <minibnz> finboyslick i have that on a poster on my door to the office...
[02:51:25] <FinboySlick> It's a brilliant statement.
[02:51:43] <FinboySlick> Almost as good as: "Hold my beer and check this out." -- famous last words
[02:51:47] <minibnz> yup.. straight to the point..
[02:52:11] <Valen> 400w of laser would be nice
[02:53:02] <minibnz> and if it will only cost me $1000 for the laser head with optics thats a great price... compared to the comercial units.
[02:54:00] <minibnz> as for the XYZ gantry thats cheap enough for my mate to make to take a full sheet. and being a solid state diode i can mount the entire thing on the gantry and not have to deal with all the BS of side mounting a tube...
[02:54:31] <minibnz> at least thats my plan.. take small steps... before i lash out and buy me a big ass diode...
[02:55:11] <minibnz> my mate would really like to be able to cut 12-16mm steel.. i dont require that, 8-10mm will be plenty for me...
[02:55:38] <Valen> dude plasma
[02:55:58] <Valen> we are making a half sheet router/mill at the moment
[02:55:58] <minibnz> can anyone here tell me if its possible to cut 16mm steel with a laser that is underpowered? my thinking would be using air assist, and multiple passes..
[02:56:20] <Valen> 16mm steel is *thick* i don't know of anybody who would use a laser to do that
[02:56:22] <Valen> use a plasma cutter
[02:56:48] <minibnz> Valen plasma would be acceptable for some of our jobs but we need accuracy for this particular job he has in mind. he want to make steel bellhousings for gearbox conversions.
[02:57:02] <Valen> then rough it with a plasma then finish it in a mill
[02:57:12] <Valen> or just mill it
[02:57:44] <Valen> your going to get a significant taper over that thickness with pretty much anything
[02:57:54] <minibnz> Valen that will require a LARGE cnc mill, the X2 is not upto that job, we would love to buy a bigger mill in the future..
[02:58:15] <Valen> if you can build a table that big for a laser, just beef it up some and stick a spindle on it
[02:58:34] <Valen> ok its not going to do it in 5 minutes but it'll work better than a laser and it'll be right
[02:59:07] <minibnz> Valen this is true, we were thinking of making the head tilt so we can compensate for the tappering effect.
[02:59:22] <minibnz> oh i realise it wont be a quick process..
[02:59:30] <Valen> you now have a 5 axis laser thats not going to cut the steel lol
[02:59:58] <minibnz> heheheh
[03:00:12] <Valen> if he wants a big mill relatively cheap we can look at making something for him
[03:00:18] <minibnz> i was thinking of getting diodes with a 1064mn wavelength..
[03:00:48] <Valen> I don't know of anybody lasering steel thicker than a mm or so
[03:00:55] <Valen> its either plasma or water
[03:00:56] <minibnz> yeah building a big mill is an option..
[03:01:17] <Valen> I'd suggest that it'll be cheaper and work better than the laser
[03:02:27] <Valen> you need lasers like this http://www.youtube.com/watch?v=6b7C9AMNAbw
[03:02:40] <minibnz> Valen i have spoken with a few people that have hinted that a multi pass cut is possible. they say the trick is to make sure you let the job cool down.. between passes.. as if you get too much heat into the job the sheet will warp.
[03:02:56] <Valen> you would need to be doing vaporisation cutting
[03:03:00] <Valen> burn the steel off
[03:05:46] <minibnz> yeah thats what the air assist is for.. my understanding is (it could be wrong) the laser heats up the metal and the air blasts it out of the way.. if the sheet metal is too thick it assorbs too much of the power and doesnt vaporise but it melts into a pool. this is when you would need the air stream to blast it out the kerf.
[03:06:26] <Valen> I havent heard of people doing that, they use the air to blow it out the back side as a rule
[03:07:10] <minibnz> hmm ok i could have it wrong and the air needs to blast it down..
[03:07:18] <Valen> it would probably work
[03:07:23] <minibnz> i guess i will just have to try it out and see :)
[03:07:35] <Valen> but still, it feels like your solving the problem from the wrong end
[03:07:38] <Valen> just mill it
[03:07:54] <Valen> if you took 1mm passes with a 6mm cutter its only 16 passes
[03:07:55] <minibnz> i would expect the air pressure needed would be pretty strong to get it up and out of a blind hole...
[03:08:06] <Valen> it would be the velocity you would need
[03:08:33] <minibnz> ahh yeah more speed than pressure..
[03:09:09] <minibnz> i would have a probelm of the motlen metal being sprayed upwards towards the lens.... which could be bad...
[03:09:14] <Valen> yup
[03:09:19] <Valen> plasma
[03:09:21] <Valen> water
[03:09:22] <Valen> milling
[03:09:48] <Valen> we often get stuff plasma cut out of stupid hard steels and they are within a mm or so

[03:12:29] <Valen> like $150 or so for a 350mm disk
[03:12:46] <minibnz> hmmm i will talk to my mate and see what he thinks about a plasma/ then mill process..
[03:13:08] <Valen> don't plasma biz then machine it, the HAZ goes hard as crap lol

[03:15:23] -!- zzolo has quit [Client Quit]
[03:15:25] <minibnz> Valen he wants to make them to order. so he will basically use a whole sheet to make his parts then put them aside until they are needed..
[03:15:52] <Valen> i mean are they all the same?
[03:15:56] <minibnz> the tricky part is that they will not be all the same as he want to be able to mkae them suit any car.
[03:16:02] <Valen> ahh
[03:16:10] <minibnz> this is why it would need a CNC mill for clean up..
[03:16:12] <Valen> how many a week is he planing on?
[03:16:33] <minibnz> not that many.. mabey 2-3 a week
[03:17:00] <Valen> I'd suggest then he talk to precision oxycut (or some of the other places around the place) and batch them up and get them cut
[03:17:17] <minibnz> hmmm interesting....
[03:17:28] <Valen> in mild steel with a working relationship he would probably be looking at like $100 for the order of 3
[03:17:41] <Valen> 1-2 weeks turn around though
[03:18:04] <minibnz> oh by the way there are places around that will happily laser cut 16mm steel... its just that it needs a 7.5kw laser...
[03:18:12] <Valen> thats my point
[03:18:12] <minibnz> 1-2 weeks wouldnt be that bad...
[03:18:40] <Valen> alternatly, if you need to mill it anyway and mild is ok, just get some blanks cut from some sheet, stick it into a mill and call it done
[03:18:48] -!- Gene34 has quit []
[03:19:31] <minibnz> on the first unit there is two locating dowels that need to be milled out once the profile is done..
[03:19:58] <minibnz> he has access to a large hand cranked mill.. but not to a CNC one..
[03:20:12] <Valen> if its big enough then CnC it
[03:20:30] <Valen> hell if we can fit them on ours we'd mill them for him
[03:20:36] <Valen> it'd fit on the new one just fine lol
[03:20:38] <minibnz> heheheh this is true.. but thats a lot of work to do on someone elses mill :)

[03:22:13] <minibnz> his boss is a bit of a tool...
[03:22:30] <Valen> well he can buy a mill from us then ;->
[03:22:42] <minibnz> heheheh
[03:22:51] <Valen> what size are his parts?
[03:23:36] <r00t4rd3d> http://i.imgur.com/flG24n8.jpg
[03:23:58] <minibnz> the first one is a bellhousing for a alpa.. its about 450mm diameter
[03:24:57] <Valen> kinda large
[03:25:09] <Valen> wont fit onto our current mill unfortunatly
[03:25:13] <minibnz> yeah
[03:25:21] <Valen> new one is 1200x1200x600
[03:25:24] <Valen> that'll do it ;->
[03:25:44] <minibnz> thats what we found you need a large unit to work that size job.
[03:25:45] <Valen> its the toy one, the "good" one will be 600mm to a side but will weigh ~600kg
[03:25:56] <minibnz> dang...
[03:26:04] <Valen> its the not a toy one ;->
[03:26:39] <minibnz> thats some heavy metal.... my mill is a toy it weighs 45kg.. i can carry it up my stairs without assistance.. (i do break a sweat)
[03:26:48] <Valen> its composite
[03:26:55] <Valen> epoxy granite
[03:26:57] <minibnz> ahh i see....
[03:27:00] <Connor> andypugh: Not my build.. Not sure why he went with a VFD vs something else. I know he's doing everything single phase.. so that might be why.

[18:23:39] <rizo> is there some axis.home-sw output - i need to signal to bldc.init to start home sequence. Which one should i use then, the bldc home sequence or the axis home sequence?
[18:24:32] <pcw_home> BLDC home has nothing to do with Axis home
[18:25:02] <andypugh> In fact, bldc-init should be avoided if at all possible :-)
[18:25:27] <rizo> arent they all connected through index-enable pin/signal
[18:25:57] <andypugh> Not necessarily.
[18:26:20] <pcw_home> sequence is something like machine-on --> BLDC init (motor rotor homed so controllable)
[18:26:22] <pcw_home> then normal axis home
[18:27:33] <pcw_home> BLDC only looks at the index enable signal when doing its init (QI mode)
[18:28:15] <rizo> i have to start the i have to somehow tell the bldc. to init otherwise it wil not latch the encoder value at index-enable
[18:28:59] <pcw_home> yes normally machine on starts the BLDC init process (for mode that need it)
[18:30:01] <andypugh> rizo: What sort of motor is it? Do you have Hall signals?

[18:34:38] <pcw_home> andypugh: BLDC must drive index enable in QI mode so does this interfere with homing on index?
[18:36:08] <pcw_home> plain old Q mode might work if theres a problem with QI and axis homing on index
[18:36:34] <rizo> what is QI mode?
[18:36:49] <rizo> i have bldc qi
[18:36:59] <rizo> if this is whyt you mean?
[18:37:09] <pcw_home> yes
[18:38:32] -!- xxoxx has quit [Read error: Connection reset by peer]
[18:40:46] <andypugh> Hmm, so bldc needs to drive index-enable, and so does the homing sequence.
[18:40:59] <andypugh> It is a bidirectional pin, so it might be OK.
[18:41:56] <andypugh> But you would then normally connect the bldc-init pin to machine-is-on
[18:42:14] <rizo> but i have to start the home at axis (set the search_vel to 0) and bldc at same time?
[18:42:41] <andypugh> I don't think so.
[18:43:20] <andypugh> You would home the motor immediately, then find the home switch once the motor is working. The motor won't work until bldc has init-ed.
[18:43:26] <rizo> I did connect the bldc-init to axis.0.amp-enable-out but it is switched off because of following error.
[18:44:26] <andypugh> Hmm, yes, I have been here before.
[18:44:38] <pcw_home> machine on is probably more appropriate
[18:45:35] <rizo> Ok, but machine on is power on, i probably need a bit of pause?

[18:46:24] <pcw_home> If machine-on powers the drives. perhaps
[18:47:17] <andypugh> The way to do this (I just remebered) is to put the bldc comoponent between the button and machine-on.
[18:47:22] <andypugh> Let me work out the pin names.
[18:47:49] <Tom_itx> andypugh, we need pics of your mold making progress now
[18:47:56] <andypugh> So, you turn on the machine, and then the bldc components init, and then the init-done pin is used to enable the acis.
[18:48:33] <IchGuckLive> yeah the position in hal is realy importend
[18:48:38] <Tom_itx> andypugh, if the .75 stepover is too much/little i can change that pretty easy

[18:56:53] <andypugh> rizo: I am getting slightly confused about how I did this previously.
[18:57:47] <andypugh> I think you only get f-errors with the machine on.
[18:58:15] <andypugh> So, you need to start the alignment sequence as soon as you go out of e-stop. Which doesn't actually sound ideal.
[18:58:20] <rizo> machine on is machine-power?
[18:58:51] <andypugh> I am talking in terms of the Axis UI, so that is the F2 button.

[19:02:35] <rizo> which is wrong.
[19:02:50] <pcw_home> I think you want F2 to start the BLDC init and BLDC init done to enable motion
[19:02:53] <andypugh> Is 0 the home position?
[19:03:20] <rizo> I cant, because the following error shut the F2

[19:14:23] <pcw_home> Can you check this? (set index enable true by hand, move carriage by hand to index)
[19:15:11] <pcw_home> encoder position should be set to 0 and index enable pin cleared
[19:15:16] <rizo> i did that, that trigers the index-done
[19:15:30] <rizo> but just for bldc, not for axis UI
[19:16:04] <andypugh> That is the answer to a different question...
[19:16:04] <pcw_home> is the encoder count cleared in axis?
[19:16:12] <rizo> No
[19:16:21] <rizo> Because i did not pres the f2
[19:16:33] <rizo> if i prees the f3 i get the following error
[19:16:42] <rizo> if i press the f2 i get the following error
[19:17:02] <andypugh> So, bldc inits when you go out of e-stop.
[19:17:15] <rizo> and the power is switched of, so i assume the index-enable pi is not monitored by the axis any more
[19:17:17] <andypugh> But if you then press F2 the machine f-errors?
[19:17:24] <rizo> yes
[19:17:40] <andypugh> That makes no sense.
[19:18:06] <andypugh> I thought you said that the carriage moved when you pressed "home"?
[19:18:17] <andypugh> But you can't press "home" without the machine being on?
[19:19:44] <rizo> If i power on and move the motor (by hand or electrically) i get the followng error.
[19:20:00] <andypugh> Is your PID tuned at all?
[19:20:15] <rizo> I can home bldc only if i wire it to e-stop.
[19:20:18] <andypugh> Moving the motor by hand _should_ give an f-error

[20:01:08] <JesusAlos> Ok

[20:04:28] <alan_1> cradek: Thank you very much
[20:04:54] <JesusAlos> I need create a button in axis. It must do two functions. His name pause button
[20:05:03] <cradek> alan_1: welcome, hope it has a better starting point for your changes
[20:05:14] <JesusAlos> one pause programm execution
[20:05:22] <JesusAlos> Two stop spindle
[20:06:06] -!- wboykinm has quit [Remote host closed the connection]
[20:06:07] <cradek> so backing up still further to try to understand the problem you are solving: do you want the spindle to always stop when you pause?
[20:06:13] <JesusAlos> Create a second button with two functions start programm execution and start spindle
[20:06:47] <JesusAlos> yes, I need stop spindle when push pause button
[20:06:55] <cradek> ok, you're still asking about an implementation. please describe your original problem or goal
[20:08:50] <cradek> it sounds like maybe you want your spindle-enable output to come from something like motion.spindle-forward AND NOT halui.program.is-paused
[20:08:50] <JesusAlos> is a bit long to explain, but basically, I have a hot wire cutting machine
[20:09:09] <JesusAlos> and spindle output connect to hot wire
[20:09:25] <cradek> ok
[20:09:44] <JesusAlos> yes
[20:10:04] <cradek> sorry for interrupting, please keep describing the problem
[20:10:36] -!- AR__ [[email protected]] has joined #linuxcnc
[20:11:11] <JesusAlos> the problem is if I pause the program execution spindle (My hot wire) still on
[20:11:31] <JesusAlos> so Foam burn
[20:12:30] <cradek> why do you pause it?
[20:13:23] <cradek> if you set feed override to 0% you have the same problem, or if there is G4 in the program, or feed rate is programmed very slow
[20:13:25] <JesusAlos> the same reason like some people pause his engrave machine
[20:13:28] <JesusAlos> for example
[20:14:10] <cradek> so should the wire turn off whenever there is no motion, or only when you select pause
[20:15:27] <JesusAlos> only when push pause || button
[20:16:18] <cradek> then my earlier guess is probably what you want

[21:33:39] <r00t4rd3d> whats the command again to send a axis home like g28 x0 or something
[21:34:09] <cradek> if you mean to the unoffset machine zero (not the same as homing), use g0 g53 x0
[21:34:21] <r00t4rd3d> no just to send back to 0
[21:34:58] <r00t4rd3d> i know it was g** x0
[21:35:13] <cradek> g0 g53 x0
[21:35:30] <r00t4rd3d> that wasnt what i been using
[21:36:22] <r00t4rd3d> i think JT-Shop told me
[21:37:22] <cradek> I've seen people use G91 G28 X0 but that's roundabout, leaves you in unwanted G91 mode, and may not even go to unoffset 0 depending on your setup
[21:37:37] <cradek> so you really want g0 g53 x0
[21:37:56] <r00t4rd3d> ill try it
[21:38:32] <r00t4rd3d> if it breaks stuff, im coming over and smashing your clocks
[21:39:49] <r00t4rd3d> sometimes when i hit the estop, i like to send the axis's back to where they started
[21:40:15] <r00t4rd3d> i click that mri tab g28 x0 y0
[21:40:21] <r00t4rd3d> i think it was 28
[21:40:22] <cradek> you'll forgive me for not answering your questions anymore

[23:26:28] -!- minibnz [[email protected]] has joined #linuxcnc
[23:27:25] <andypugh> spindle-rpm-filtered is just a signal name. It needs a source. All you have done so far is create a signal called spindle-rpm-filtered and connect it to the PyVCP. There is nothing writing to the signal.
[23:28:00] -!- sumpfralle has quit [Ping timeout: 252 seconds]
[23:28:23] <andypugh> The firs thing after the net command is a signal name. You can choose any names you want. None of them exist until your HAL file creates them.

[23:40:29] <JesusAlos> the most similar i found is override spindle

[23:54:43] <tjb1> Is that a slip roll in the back right?
[23:54:51] <JT-Shop> it took me 44 years to get this job
[23:55:09] <JT-Shop> yea, a 3 in 1 sheet metal machine
[23:55:20] <tjb1> What gauge can you roll
[23:55:59] <JT-Shop> depends on the width but not much with that little thing, maybe 16 gauge
[23:58:13] <JT-Shop> 22 gauge for the slip roll and brake and 28 gauge for the shear
[23:58:24] <tjb1> That's like tinfoil :(
[23:58:54] <tjb1> My idea for fireplace rings went down unless I can find a way to make a circle with like 1/16
