[00:04:33] <XXCoder> http://i.crackedcdn.com/phpimages/article/9/3/6/493936_v1.gif type gcode on this I dare you
[01:49:13] <archivist> Meduza, a drawing of the machine?, what is the machines function (drawing/cutting etc)
[02:03:48] <archivist> Meduza, also see http://linuxcnc.org/docs/html/motion/kinematics.html
[02:31:21] <Deejay> moin
[04:25:53] <Apastrix> Hello guys, how to change kinematics from trivial to some over option given by linuxCNC?
[04:30:27] <archivist> Apastrix, http://linuxcnc.org/docs/html/motion/kinematics.html
[04:31:00] <archivist> and the implementers manual
[04:38:26] <Apastrix> archivist, thanks i already read that and didn't understand a thing, where can i click to change the kinematics exactly?
[04:40:05] <archivist> you would edit the configs to load the kinematics you wrote/compiled
[04:41:11] <Apastrix> I don't want to write kinematics, i don't know the math behind them, i just want to use something available.
[04:42:09] <archivist> for what type of machine
[04:43:15] <Apastrix> i want to build a simple 6 axis robot (as simple as it can get), since i'm mach3 can't handle joint kinematics, i'm turning to linuxcnc
[04:44:08] <Apastrix> in youtube a lot of people used it to control their robots so i'm looking on how to use it like they did.
[04:45:10] <archivist> ok where a standard machine uses trivkins you would use one of http://linuxcnc.org/docs/html/man/man9/kins.9.html
[04:46:58] <Apastrix> yes this is exactly my question, how to use one of these? can i access these from the gui interface? where do i click?!
[04:47:14] <archivist> I am not aware of any pointy clicky setting up of these, one edits the files
[04:48:00] <archivist> too much variation for simple guis to set up
[04:48:37] <Apastrix> i'm guessing i need to change the HAL file, right?
[04:48:50] <archivist> yes
[04:49:53] <Apastrix> it seems to be a hard thing, but i will try it out, thanks for your help!
[04:50:21] <archivist> it takes a bit of thinking to get used to, like riding a bike :)
[05:09:50] <rhavenj__> hi there, id really appreciate some suggestions. I have bought a used cnc machine. It comes with a controller card SMC 800. https://www.conrad.de/de/emis-3-achs-schrittmotor-steuerkarte-smc-800-betriebsspannung-15-30-vdc-phasen-strom-max-08-a-anzahl-steuerbarer-achsen-3-967599.html The computer I was going to use it with is now dead. I have the choice now of either buying a pc (mini itx probably), or buying a new card.
[05:10:16] <rhavenj__> Does anyone have experience with these usbcnc cards?
[05:14:30] <rhavenj__> do they work well with linuxcnc?
[05:15:39] <malcom2073> I don't believe linuxcnc supports any of the usb cards, since they're unneccesary
[05:15:47] <malcom2073> That card you linked is just a stepper driver
[05:16:00] <malcom2073> Not a controller
[05:17:25] <rhavenj__> yes driver, thanks
[05:17:55] <rhavenj__> malcom2073, why unecessary? i dont need a parallel connenction anymore
[05:18:22] <malcom2073> rhavenj__: Linuxcnc handles all the control via parallel port (and does a much better job than any of the usbcnc cards do)
[05:18:26] <renesis> i think its a latency issue
[05:18:36] <renesis> malcom2073: dude parports done exist
[05:18:47] <renesis> my last mobo i had to dongle onto a pinhead on the mobo
[05:18:57] <renesis> also linuxcnc drives more than parports
[05:19:01] <malcom2073> renesis: Really? There's a couple linked on the linuxcnc wiki you can buy brand new with par ports
[05:19:11] <renesis> pretty sure the usb thing has to do with usb
[05:19:14] <malcom2073> Also yes, there are other options, like mesaboard
[05:19:44] <renesis> a couple
[05:20:09] <renesis> so basically .001% of the market
[05:20:42] <renesis> er, *pretty sure the usb thing has to do with latency
[05:21:03] <malcom2073> And redundancy, no point in having the control loop both in a card, and linuxcnc
[05:21:17] <rhavenj__> so recomendation is to buy a computer with par port correct?
[05:21:21] <renesis> yes
[05:21:54] <rhavenj__> advantages of the fpga boards?
[05:22:06] <malcom2073> significantly faster step rate, more I/O
[05:22:16] <malcom2073> Servo capabilities if you need them
[05:22:24] <rhavenj__> cost++
[05:22:33] <malcom2073> Indeed, significant cost increase
[05:22:34] <rhavenj__> or are they down in price ?
[05:22:37] <rhavenj__> o=k
[05:23:08] <malcom2073> Well not significant, I think the fpga card is like $80, and the breakout board is like $120 iirc?
[05:23:18] <malcom2073> It's been a while since I've looked
[05:24:32] <rhavenj__> is there a page where i can find linuxcnc suported boards?
[05:24:56] <rhavenj__> nvm i found it sorry
[06:29:37] <Meduza> archivist: I dont have all the parts drawn up yet, but this is the Z-axis, the rotating axis and the tool: https://www.dropbox.com/s/wrblxunsje3yfqu/2016-01-11%2012_57_22-Autodesk%20Fusion%20360.png?dl=0
[06:30:29] <Meduza> and that tip is on about a 100mm radius from the center of the rotating axis
[06:31:41] <Meduza> and it is mounted to a classic X-Y gantry
[06:38:07] <Meduza> and the surface it will work on is paralell to the X-Y plane
[06:39:44] <archivist> can you use imgur or better dropbox gives a white screen
[06:40:48] <Meduza> https://imgur.com/7PI86u3
[06:40:56] <Meduza> there you go
[06:42:39] <archivist> sort of like a drag cutter
[06:43:26] <Meduza> yes, quite similar, just with a way larger tip offset than ususal drag cutters
[06:44:06] <Meduza> (i belive the roland drag cutters for vinyl i did work on a few years back had about 0.25mm tip offset)
[06:45:17] <archivist> I think you could make something of a kins to suit but I am guessing this needs something extra to know the direction
[06:47:44] <archivist> well command the direction (in line with path)
[06:48:17] <Meduza> yes, i need to be able to command the direction and the X-Y-Z point in space
[06:48:18] <archivist> the kins can then easily offset the xy to suit
[06:50:01] <archivist> by convention that rotary would be C I suppose
[06:51:25] <Meduza> i suppose so, even if most C-axis i have seen has been affixed to the table and not to the head
[06:53:59] <archivist> there is a youtube where someone did a c table and showed it working offset, should be close enough starting setup for you
[06:57:51] <Meduza> *searching youtube*
[06:59:47] <archivist> one of them https://www.youtube.com/watch?v=Oh9eCupbsso
[07:00:24] <archivist> the other I wanted to find was a university done unit
[07:02:49] <archivist> this one where it is deliberately offset https://www.youtube.com/watch?v=DjPCEpZybXs
[07:03:10] <archivist> vids not working for me properly today
[07:12:38] <Meduza> archivist: that looks nice and to be something similar to what i want to achieve
[07:13:25] <archivist> yup shows the offset nicely
[07:14:26] <archivist> just you are using one rotary so have less to calculate
[07:15:49] <Meduza> Exactly
[07:20:10] <Meduza> Now... How do i actually do this :p I guess i have to create a kinematics file with a mathemathical definition of the movements
[07:20:14] <Meduza> ?
[07:38:47] <archivist> something like that yes http://linuxcnc.org/docs/html/man/man9/kins.9.html and the source code
[07:48:44] <archivist> although I have 5 axis I have never needed to do this as it is probably as easy to write into the gcode
[07:50:55] <Sync> if you have a cam software that can do it, probably
[07:51:05] <Sync> but for most things you want to have to control do it
[07:57:03] <Meduza> i will have to write a script to create the g-code, and yes, i would rather do this in the control than in the gcode generation
[08:01:05] <Swapper> anyone here that runs a stepper config on a mesa 5i25 (hw stepgens) and know what would be sane values in the pid regulator?
[08:01:27] <Swapper> PCW said somting about PNCCONF entering the wrong value
[08:01:32] <Swapper> for P
[08:59:21] <max12345> hello I have a setup here where someone configured some custom buttons, where I can find the how to for that in the documentation?
[09:07:14] <JT-Shop> the manual comes to mind, a look at your postgui.hal file might give a clue
[09:31:22] <max12345> I have found a chapter about homing configuration, it says to set some internal variables, how do I do that?
[09:33:14] <cradek> I don't understand your question - what problem are you having?
[09:37:10] <ReadError> max12345 http://gnipsel.com/linuxcnc/gladevcp/index.html ?
[09:38:53] <max12345> ReadError: thanks, that looks very much like what I'm looking for
[09:39:19] <max12345> cradek: http://linuxcnc.org/docs/2.7/html/config/ini-homing.html#cha:homing-configuration I'm talking about this page
[09:39:38] <max12345> I don't know how to set internal variables
[09:40:21] <cradek> oh like SEARCH_VEL? those are just in the ini file. you just edit the file.
[09:40:50] <max12345> cradek: ok cool, I'll look for that...
[10:23:52] <maxcnc> hi all
[10:24:22] <maxcnc> Q: is there a chance to get a #12 var to be shown to a pyvcp number
[10:24:35] <archivist> yes
[10:24:38] <maxcnc> during g-code run
[10:25:18] <maxcnc> archivist do you got a example for me
[10:31:38] <archivist> maxcnc, you see here http://www.archivist.info/cnc/configs/vertex/custompanel.xml
[10:32:01] <archivist> I connect a number to a pin, then you can connect that to whatever
[10:33:12] <maxcnc> ok
[10:33:41] <archivist> where is the number really from
[10:38:22] <archivist> there are some special pins on the motion comp to put numbers back into a variable see motion.analog-in-00
[10:39:13] <archivist> http://www.archivist.info/cnc/configs/vertex/vertex.hal
[10:39:19] <maxcnc> i think i need to do a coustom mcode then recalculate it there and do a halcmd to set the number to a userdefind in the hal itself
[10:39:49] <archivist> http://www.archivist.info/cnc/configs/vertex/custom_postgui.hal
[10:40:28] <maxcnc> il get it
[10:58:52] <ssi> sparkfun has gone solidly to shit :(
[10:59:44] <FloppyDisk> in what way?
[10:59:50] <FloppyDisk> :-(
[11:00:09] <ssi> I ordered some edison stuff from them because for some reason I can't get it on amazon
[11:00:19] <ssi> I ordered it on thursday and they haven't shipped it yet
[11:00:29] <ssi> I used to buy from them alllll the time
[11:00:30] <FloppyDisk> Oh my..
[11:00:42] <ssi> but a couple years ago I ordered $250 worth of xbee crap and USPS lost it
[11:00:48] <FloppyDisk> Ugh...
[11:00:53] <ssi> and sparkfun's response was "sucks for you, maybe you shouldn't use usps"
[11:01:27] <ssi> and I mean... I was a customer of theirs in 2005
[11:01:35] <ssi> I used to use their batch pcb service before they spun off batchpcb.com
[11:01:40] <FloppyDisk> Yeah, the usps thing can be a problem - no doubt. But, its cheaper and often faster than alternatives.
[11:01:46] <ssi> yes exactly
[11:02:05] <ssi> I can't fathom paying $16 to ship an envelope worth of stuff across the country in nine days
[11:02:11] <ssi> when I can pay $6 to ship it in two days
[11:02:30] <FloppyDisk> yup...
[11:20:47] <CaptHindsight> Royal Mail is worse
[11:22:15] <archivist> how could you say such a thing!
[11:23:22] <archivist> beats me how stuff from hong kong gets here cheaper than just a few miles
[11:26:39] <jdh> lack of subsidy and mis-valued currency?
[11:26:59] <ssi> lol
[11:28:05] <archivist> they hiked prices when they were privatised
[11:30:16] <roycroft> just wait until the nhs is completely privatised
[11:30:25] <roycroft> you'll be paying as much as we do for health "care"
[11:30:56] <archivist> not much sign of that happening
[11:31:16] <archivist> .gov would be out instantly
[11:31:26] <roycroft> cameron has over four years to go before he retires
[11:31:43] <roycroft> you think the backbenchers would revolt?
[11:32:11] <archivist> all MPs are revolting
[11:32:48] <roycroft> it has been an unusual parliament
[11:33:36] <CaptHindsight> archivist: sent an express 3-5 day to london on the 14th Dec, it just cleared customs after being in limbo until Jan 5
[11:33:38] <roycroft> but labour have to finish their shadow cabinet shuffle before they can stand for election, and that might take more than 5 years, the way things are going
[11:34:08] <archivist> CaptHindsight, that is customs not royal mails fault!
[11:34:33] <roycroft> i had an intersting postal experience today
[11:34:46] <roycroft> i had a parcel sent to me by amazon
[11:35:03] <roycroft> it got a "business closed" exception flag this morning
[11:35:14] <CaptHindsight> no customs clearance took 5 days, RM lost it between the 18th to the 5th
[11:35:22] <Connor> roycroft: What does that mean ?
[11:35:25] <roycroft> the thing is, it is being delivered to a post office box at the very facility that flagged it
[11:35:35] <roycroft> it means they attempted to deliver it but the business was closed so they could not
[11:35:57] <CaptHindsight> roycroft: why did you close your mailbox today? :)
[11:35:58] <archivist> that dept was on tea break
[11:35:58] <roycroft> so apparently the post office that attempted to deliver it was closed
[11:35:58] <Connor> Miss the payment on the PO Box ?
[11:36:13] <roycroft> the box is on autopay
[11:36:16] <Jymmm> David Bowie died
[11:36:25] <roycroft> and it renewed in november, so it's good for almost another year
[11:36:49] <Connor> roycroft: Someone f**k up and hit the wrong key.. probably went OUT to be delivered..
[11:37:29] <roycroft> yes, i'm sure some incompetent boob did it by mistake
[11:37:44] <roycroft> my experience, however, is that the usps can ship packages across the country in a matter of 2-3 days
[11:37:56] <roycroft> but once it hits my local post office it can take up to a week before they put it in my box
[11:38:12] <roycroft> i've learned not to hold my breath waiting for deliveries
[11:38:20] <Jymmm> Heh, I've had priority mail delivered across country in less than 24 hours before
[11:38:22] <ssi> usps moves mail fast as crap because the belly of every passenger airliner is full of us mail
[11:38:22] <CaptHindsight> they tried to privatize the USPS as well, they didn't break it so they weren't able to privatize it
[11:38:35] <roycroft> they can't privatise it
[11:38:54] <roycroft> there's this tiny obstacle called "the constitution of the united states"
[11:39:05] <ssi> lol since when is that an obstacle
[11:39:20] <Jymmm> roycroft: Since when has congress been adhering to that?
[11:39:44] <Jymmm> roycroft: "YER PAPERZ PLEEZE"
[11:40:01] <Jymmm> </schultz>
[11:40:08] <CaptHindsight> only terrorists have things to hide
[11:40:18] <Jymmm> lol
[11:40:51] <anomynous> not about being private or public if there isnt enough work force. Demand fluctuates and Bosses don't want to pay a dime too much for idle time.
[11:40:53] <Jymmm> CaptHindsight: what about this pink fishnets that are in YOUR size?
[11:40:56] <anomynous> just a thought
[11:41:51] <CaptHindsight> too big to charge
[11:41:54] <roycroft> the constitution explicitly stipulates in article 1, section 8 that the legislative branch has the power "to establish post office and roads"
[11:42:36] <Connor> My problem with USPS is they kept upscaling and upscaling and upscaling to meet demand. They now complain they're not making money.. so instead of scaling back the employee's and the locations etc.. they won't to scale back the delivery services.. I.E. Cut Saturday.. Require new subdivision have cluster mailboxes instead of individual mail boxes etc etc.
[11:42:53] <roycroft> do you know why they're not making money?
[11:43:10] <Connor> they WANT to scale back delivery services...
[11:43:16] <Connor> ugg. brain not working today...
[11:43:21] <roycroft> and why they can't scale back on delivery services?
[11:43:33] <Connor> Pension part of it..
[11:43:34] <archivist> they fixed the not making money by hiking the prices in the uk
[11:43:45] <roycroft> they're not making any money because they are required to pre-pay pensions for 75 years up front
[11:44:08] <roycroft> no other company, public or private, in the world has that kind of pension pre-payment mandate
[11:44:20] <Connor> That's the most insane thing I've ever seen.
[11:44:50] <CaptHindsight> it was designed to bankrupt the USPS so it could be privatized
[11:44:56] <roycroft> and they can't cut back on delivery servics because, although they're a private company owned by the government, our equivalent of a crown corporation, they are regulated by the congress, which will not allow them to cut back on delivery services
[11:45:06] <roycroft> yes, the congress are doing this to try to bankrupt the usps
[11:45:18] <roycroft> it's their self-fulfilling prophecy strategy
[11:45:30] <ssi> CaptHindsight: kinda like the aca was designed to bankrupt the middle class so they could make single payer happen?
[11:45:35] <roycroft> starve the teat, then complain that blame it for starving
[11:45:50] <CaptHindsight> don't let the facts get it the way
[11:46:10] <roycroft> well we should have had a single payer system in the first place
[11:46:19] <roycroft> expanding medicare is what should have happened
[11:46:28] <roycroft> instead we got this abomination
[11:46:33] <CaptHindsight> sounds like commie rhetoric
[11:46:34] <ssi> intentionally
[11:47:06] <roycroft> nobody said single provider system
[11:47:24] <roycroft> single payer and single provider are two completely, utterly unrelated things
[11:48:02] <anomynous> commie rhetoric sounds like anti-commie rhetoric. Just rhetoric, that is. And that just might make me a commie, even though I am not ;D Does it?
[11:48:28] <roycroft> i prefer not to slap labels on everything
[11:48:46] <roycroft> and just look at the merits of each individual policy in their own
[11:48:53] <anomynous> +1 roycroft
[11:49:00] <CaptHindsight> burka wearing commies
[11:49:16] <roycroft> there isn't a single example of pure capitalism in the world
[11:49:19] <roycroft> nor pure communism
[11:49:22] <roycroft> nor pure socialism
[11:49:28] <Jymmm> THUNDER DOME!!!
[11:49:29] <ssi> spending other peoples' money on other people is never the most efficient way to do anything
[11:49:30] <_methods> wtf that's crazy
[11:49:32] <roycroft> every economy is a mixed economy
[11:49:34] <_methods> the world isn't black and white
[11:49:36] <ssi> but that's none of my business
[11:49:42] <anomynous> actually there is no example of communism. They all only make it to socialism
[11:49:44] <anomynous> ;D
[11:49:57] <roycroft> when people say "he's a socialist" the answer is "you are correct, as are we all"
[11:50:03] <Jymmm> _methods: Not black and white, bullets and blood baby!!!
[11:50:10] <roycroft> it's not a matter of socialism vs. not socialism or capitalism vs. not capitalism
[11:50:12] <_methods> hehe
[11:50:15] <roycroft> it's a matter of degree of each
[11:50:33] <CaptHindsight> sorry I was on Facebook, what's all this then?
[11:50:53] <roycroft> facebook, however is an example of pure evil
[11:51:14] <anomynous> ;D actually investor of facebook said kind of the same thing
[11:53:38] <CaptHindsight> https://reason.com/blog/2015/12/17/yale-students-eagerly-sign-petition-to-r
[11:53:59] <CaptHindsight> "Yale Students Totally Cool With Repealing the First Amendment"
[11:54:21] <Jymmm> wtf?!
[11:54:26] <Jymmm> dumbasses
[11:54:44] <CaptHindsight> I want to inject your brain with window cleaner. "I don't mid"
[11:54:50] <CaptHindsight> mid/mind
[11:55:12] <roycroft> before the especially nasty trump rally friday night, where a women was thrown out just for standing up, trump campaign staffers told reporters "mr trump believes in the 1st amendment almost as much as he believes in the 2nd amendment."
[11:58:07] <cradek> roycroft: I'm glad she got out (and away from all his "fans") safely
[11:58:19] <roycroft> yes, i am too
[11:58:39] <cradek> she's braver than me
[11:58:40] <_methods> hopefully the rest of us can escape also
[11:58:50] <roycroft> trump doesn't scare me
[11:58:57] <roycroft> that so many people follow him scares me
[11:59:01] <cradek> yeah
[11:59:17] <_methods> reminds me of the lead up to third reich
[11:59:19] * Jymmm hands out the kool-aid
[11:59:19] <cradek> he has a way of concentrating the ugly americans all in one place
[11:59:21] <roycroft> i think iowa is going to be an eye opener though
[11:59:32] <roycroft> it's one thing to say you support him in polling
[11:59:53] <roycroft> it's quite another thing to actually go to a caucus and stand for him, or vote for him in a primary
[12:00:07] <roycroft> i think he's not going to do as well as he's polling in iowa or new hampshire
[12:00:09] <_methods> i can only hope it ends there
[12:00:10] <cradek> he sure may win in iowa, but iowa doesn't predict anything
[12:00:19] <_methods> it's embarassing that he's even still in the race
[12:00:25] <roycroft> it won't end until he decides to stop spending money on it
[12:00:34] <roycroft> and so far he's had to spend very little money
[12:00:45] <roycroft> the media are giving him all the free publicity he wants
[12:00:47] <cradek> it's only embarassing because so many americans are like him
[12:00:58] <_methods> it very much is
[12:01:00] <CaptHindsight> Trump just took over the meat robots created over the past couple of decades....
[12:01:10] <anomynous> i find it perplexing that such an arrogant person as trump is a president candidate and doing well. ;D
[12:01:11] <cradek> maybe it's good that the ugly is being dragged out into the light
[12:01:22] <anomynous> maybe people in usa are like trump
[12:01:27] <roycroft> well that started in 2008, when obama became the democratic nominee
[12:01:36] <roycroft> all the closet racists came out of the closet
[12:01:44] <_methods> yeah i'm afraid we're in teh minority of americans with functional brains
[12:01:45] <CaptHindsight> not difficult when they can longer think critically and just react to trained stimulus
[12:02:07] <anomynous> CaptHindsight: but maybe you are like that too
[12:02:13] <roycroft> trumpism is just a natural progression for that ilk
[12:02:13] <anomynous> CaptHindsight: underestimating others
[12:02:15] <anomynous> ;D
[12:02:21] <CaptHindsight> it's also payback time for Trump, well for his ego
[12:02:35] <anomynous> he is playing a game and people seem to like it
[12:02:42] <CaptHindsight> he got hit pretty hard with the housing collapse
[12:02:42] <roycroft> yes
[12:02:43] <_methods> i just can't wrap my brain around how this is even happening
[12:02:45] <anomynous> even though he may just think what he is saying
[12:02:55] <roycroft> but again, i'm not sure they'll keep playing when it's actually time to cast votes
[12:02:59] <_methods> i totally underestimated teh stupidity of america
[12:03:12] <cradek> do so at your peril
[12:03:25] <_methods> i mean i knew there were plenty of morons out there........
[12:03:27] <cradek> roycroft: it'll sure be interesting to see that
[12:03:27] <_methods> but this
[12:03:41] <roycroft> first of all, i would be willing to bet that a large percentage of his supporters do not vote on a regular basis, and may not be bothered to vote now
[12:03:47] <CaptHindsight> _methods: nice wake up call
[12:03:53] <_methods> i told my wife if trump wins i'll build a rocket ship out of my own feces and fly to canada
[12:04:05] <anomynous> _methods: good plan :D
[12:04:12] <_methods> i won't live in a country with that asshat running it
[12:04:12] <roycroft> sadly, cruz would be even worse than trump
[12:04:19] <ssi> what you fail to realize, is that we're all fucked no matter who wins
[12:04:25] <_methods> this is true
[12:04:35] <CaptHindsight> it might take 8 years-o Trump to turn things around
[12:04:38] <roycroft> i'd rather be ruled by a bigoted bully than a theocrat
[12:04:41] <_methods> the choices are pretty damn pathetic
[12:05:10] <ssi> we can have the bully, the theocrat, the shrieking lying harpie, or the socialist who doesn't understand economics even a little bit
[12:05:11] <CaptHindsight> like a junkie that needs to hit rock bottom
[12:05:45] <roycroft> we need serious electoral reform before any of this can be fixed
[12:05:54] <_methods> yeah
[12:05:55] <ssi> it can't be fixed
[12:05:58] <ssi> we're well past that point
[12:05:59] <_methods> it should be like jury duty
[12:06:00] <roycroft> sure it can
[12:06:10] <_methods> 2 years
[12:06:11] <ssi> we're solidly into panem et circensen territory
[12:06:12] <roycroft> we're too great a nation to just die
[12:06:25] <anomynous> roycroft: so you rather choose evil rather than God, even though you know it is rotten? Is that what you meant by theocracy thing? I don't know how those two things are related, but im just curious.
[12:06:36] <_methods> randomly selected and verified by peers to fill all positions
[12:06:41] <ssi> roycroft: nice thought, but I don't think you're right :/
[12:06:44] <_methods> that would stop all the career politician bullshit
[12:07:08] <roycroft> i can't choose that which i believe does not exist
[12:07:09] <ssi> _methods: that's actually an awesome idea
[12:07:13] <_methods> and any corruption would be caught by the next appointee
[12:07:13] <ssi> but I don't think it'll happen
[12:07:19] <CaptHindsight> it's been cleverly redesigned to not change very quickly
[12:07:21] <roycroft> besides, theocracies have nothing to do with "god"
[12:07:29] <roycroft> they're all about power in the name of "god"
[12:07:46] <_methods> yeah it won't change because too many crooks got their hands in teh cookie jar
[12:08:01] <ssi> it won't change because the people who would have to change it are the ones who would be deposed
[12:08:35] <anomynous> roycroft: well, isn't choosing a president a matter of society? Not religion. How does this faith or belief affect negatively in those matters?
[12:08:37] <roycroft> 1. full, complete public finance of elections - no private money allowed
[12:08:40] <cradek> good thing god is a capitalist now, and all that christian charity stuff is out of style
[12:08:57] <roycroft> 2. an end to gerrymandering - redistricting is done by non-partisan committees
[12:09:18] <_methods> if it was done like jury duty you wouldn't have to worry about any of that
[12:09:22] <_methods> no more campaigns
[12:09:24] <_methods> no more elections
[12:09:29] <roycroft> 3. politicians should be penalized for lying about their policys and about their opponents
[12:09:40] <roycroft> that's how things should start
[12:09:41] <_methods> build barracks at DC and you live in them while you're there
[12:09:42] <anomynous> then vote a person who doesnt lie
[12:09:46] <CaptHindsight> _methods: like ancient Greece
[12:09:50] <ssi> _methods: except that the kind of people you want representing you are the kind that can't afford to put their lives/careers on hold for two years to go serve
[12:09:50] <_methods> yeah
[12:09:51] <roycroft> a proportional representation system would be the next step
[12:09:59] <_methods> and pay would be the mean pay for your state
[12:10:01] <anomynous> instead you say you vote someone who just wants it all for himself
[12:10:05] <_methods> while you serve your time
[12:10:07] <roycroft> i really like the mechanism used in scotland for the scottish parliament
[12:10:11] <anomynous> does that mean you are alike to that person?
[12:10:14] <Jymmm> Cool... https://www.youtube.com/watch?v=tWIJVQwHN98
[12:10:14] <_methods> whatever your state's median wage is
[12:10:18] <roycroft> the parties have constituency candidated and list candidates
[12:10:35] <roycroft> the consituency candidates represent individual constituencies, i.e. districts
[12:10:40] <ssi> _methods: so for my state that number is $44,670
[12:10:44] <_methods> yep
[12:10:46] <CaptHindsight> these are all great ideas but how do you get anyone to make the guberment do any of this?
[12:10:49] <_methods> that's what you get paid while you do your duty
[12:10:51] <ssi> so should I take a $100k pay cut for two years because my name got picked?
[12:10:51] <roycroft> and are elected first past the post
[12:11:01] <roycroft> however, there are "list" positions as well
[12:11:03] <ssi> it'll never fly
[12:11:07] <_methods> yes unfortunately if you want to be a citizen
[12:11:27] <ssi> and if I had a family that didn't have another income source?
[12:11:32] <ssi> we just go into poverty for awhile?
[12:11:32] <roycroft> and list candidates are chosen so that representation is roughly equal to each partie's total vote
[12:11:37] <ssi> I lose my job and have to restart my career afterwards?
[12:11:37] <roycroft> party's
[12:11:38] <_methods> yep 2 years
[12:11:40] <CaptHindsight> how do we even fix our vote counting system?
[12:11:49] <ssi> it's the same as going to prison for 2 years
[12:11:51] <ssi> that ruins peoples' lives
[12:11:55] <roycroft> they're essentially at-large positions
[12:11:55] <_methods> citizens need to sacrifice sometimes for the good of our country
[12:12:02] <_methods> like our forefathers who gave thier lives
[12:12:07] <archivist> vote Monster Raving Loony
[12:12:12] <roycroft> in 2010 more people voted for democrats for congress than republicans
[12:12:13] <_methods> you can survive a couple years eating ramen lol
[12:12:23] <roycroft> yet the republicans took the house by their largest majority in decades
[12:12:28] <roycroft> because of gerrymandering
[12:12:40] <_methods> it would be like national guard/reserve soldiers now
[12:12:44] <CaptHindsight> the plan worked well
[12:12:47] <_methods> they go do their duty when they get called up
[12:12:52] <_methods> then come back to their jobs
[12:12:54] <ssi> _methods: they get to elect to do that
[12:13:00] <ssi> it's not compulsory
[12:13:06] <_methods> yes
[12:13:10] <ssi> and countries that have compulsory military service do so for 18 year olds
[12:13:19] <ssi> not established people with families and homes and careers and obligations
[12:13:29] <_methods> well i also believe people should have to perform compulsory civic service
[12:13:33] <_methods> 2 years
[12:14:10] <ssi> I'll do 2 years compulsory civic service if it opts me out of being taxed to death for entitlements for the rest of my life
[12:14:17] <_methods> heheh
[12:14:29] <CaptHindsight> _methods: how does your plan ensure continued corruption? I don't follow :)
[12:14:34] <_methods> yeah maybe i'm expecting too much
[12:14:52] <ssi> jury duty is already a massive imposition an productive humans
[12:14:57] <ssi> and that's like what, a week maybe?
[12:15:07] <ssi> and it's all such a ridiculous farce
[12:15:10] <_methods> yeah it's pretty sad
[12:15:18] <CaptHindsight> I saw a movie where it went on for a month
[12:15:20] <_methods> everyone wants something but nobody wants to contribute
[12:15:43] <anomynous> true, true
[12:15:45] <ssi> even our election system is that way... there's little incentive to vote in any case, but add to that the fact that some of us have to take a damn day off work to do it
[12:16:22] <CaptHindsight> what do you expect from a nation of mostly narcissists? It's not even a disorder anymore
[12:16:41] <roycroft> i don't have to take a day off
[12:16:51] <roycroft> we were the first vote-by-mail state in the country
[12:17:26] <roycroft> and while at first i missed going to the polling place on election day, i'm very happy with our system now
[12:17:26] <CaptHindsight> just use those electronic (x86) voting machines :)
[12:17:30] <roycroft> no voter suppression issues
[12:17:38] <roycroft> no electronic voting machiens
[12:17:40] <CaptHindsight> results anyway you like them
[12:17:46] <roycroft> every ballot is hand-marked and is auditable
[12:20:52] <CaptHindsight> most people spend age 5-19 in schools being well conditioned to fit into what's been well designed this way
[12:22:43] <CaptHindsight> it will to a generation or two for things to change, unless there is some great catastrophe like scifi-virus war, meteor etc
[12:24:07] <roycroft> effective change always takes time
[12:25:06] <roycroft> things have changed a lot since i was young, and although it seems we're taking steps backwards at times, we take more steps forward, and we're really a better society than we ever have been
[12:25:18] <roycroft> looking at society as a whole
[12:25:19] <the> guys, does anyone use ngcgui for lathe? i just installed it but dont have any idea how to set it up, use it...
[12:25:56] <roycroft> oh lovely, i have to head out shortly to the job site and it just started raining really hard
[12:27:28] <CaptHindsight> rain! it's 5F here
[12:27:36] <Jymmm> roycroft: https://www.youtube.com/watch?feature=player_detailpage&v=aopdD9Cu-So#t=29
[12:30:01] <roycroft> note that i am not where you are by intent, capthindsight :)
[12:33:37] <CaptHindsight> todays weather is cold with razors on your face when the wind blows followed by even colder later
[12:33:55] <_methods> yeah it's like 50f here
[12:34:00] <_methods> i'm gonna get hypothermia
[12:34:21] <_methods> i had to wear a sweatshirt
[12:34:23] <_methods> wtf
[12:34:34] <roycroft> it looks like we'll get rain every day for at least the next week
[12:34:46] <roycroft> but also, we shouldn't dip below freezing for at least the next week
[12:34:48] <_methods> that's what you get for living in th pnw
[12:35:07] <the> guys think yourself lucky, in germany we will get rain and snow for the next 3 months...
[12:35:36] <CaptHindsight> it has to warm up here before it can snow
[12:36:55] <the> CaptHindsight, where are you?
[12:38:21] <roycroft> the: i live in western oregon
[12:38:30] <roycroft> we get rain for about 9 months out of the year
[12:38:33] <the> lol...
[12:38:36] <roycroft> but rarely snow
[12:38:51] <the> pretty good mix of weather in the fatherland...
[12:38:53] <roycroft> we have two seasons: the rainy season and the tear up the roads season
[12:39:13] <the> does anyone use linuxcnc with a lathe?
[12:39:53] <CaptHindsight> the: http://www.wunderground.com/US/Region/Midwest/2XTemperature.html
[12:44:21] <the> no takers?
[12:45:07] <FloppyDisk> many do, just not me and the others must not be on or busy...
[12:46:14] <FloppyDisk> I googled "ngcgui tutorial" and there are a few youtube vids, not sure they help or not... Someday, I'd like to get a lathe,
[12:46:19] <FloppyDisk> but need to clean up the garage
[12:47:36] <the> FloppyDisk, I have the machine in front of me, trying to play with it now..
[12:47:51] <FloppyDisk> nice, sounds like fun:-)
[12:47:56] <the> FloppyDisk, just push everything into a corner :-)
[12:48:06] <the> steep learning curve..
[12:48:25] <Roguish> roycroft: how's Bend these days?
[12:48:48] <FloppyDisk> Been doing that (corner). Yes, steep learning curve, but I notice it's getting easier for the mill as I do more and read more.
[12:52:51] <the> FloppyDisk, lol.. yes, the start is the hardest i think, once you get started its better. appear to have basic turning working :-)
[12:53:26] <the> FloppyDisk, i also have a milling machine but i have to finish the electrical stuff to get it going...
[12:53:39] <the> FloppyDisk, i just got the lathe refitted..
[12:53:56] <the> FloppyDisk, was easier to do that than learn linuxcnc...
[13:09:55] * JT-Shop puts on the bibs and heads outside to do some lumberjacking
[13:10:21] <the> JT-Shop, you there dude?
[13:10:29] <manpo> hi
[13:10:50] <maxcnc> ;-) archivist
[13:10:55] <maxcnc> it works fine
[13:11:15] <the> JT-Shop, I have ngcgui setup and it appears to be working :-)
[13:11:26] <maxcnc> i did a postgui net showval pyvcp.num
[13:11:32] <the> JT-Shop, not exactly sure what I am doing yet though...
[13:12:22] <maxcnc> then in a user mcode i did halcmd sets showval parameter
[13:12:38] <the> JT-Shop, just tried out the OD function with appears to work but wanted to go to G54 origin at the end of the cycle which would have crashed the machine, lucky I was paying attention :-)
[13:12:42] <maxcnc> and in gcode the Mxxx P#12
[13:13:14] <maxcnc> the OD ?
[13:13:50] <the> maxcnc, me?
[13:13:53] <maxcnc> yes
[13:14:04] <maxcnc> what is OD
[13:14:39] <the> maxcnc, the ngcgui OD function - turns the OD to size...
[13:15:01] <the> maxcnc, i am trying to learn to use my lathe..
[13:15:35] <maxcnc> ah lathe the hell of rotatio
[13:15:36] <the> outside diameter...
[13:15:48] <the> lol..
[13:16:22] <maxcnc> im only in 3d(2.5) no rot
[13:16:40] <the> need to know why it wanted to end at the G54 origin and not the end of the work :-)
[13:17:07] <the> i also have a milling machine but its not quite put together yet...
[13:17:19] <the> doing the electric stuff now.
[13:17:40] <maxcnc> http://linuxcnc.org/docs/html/gui/ngcgui.html
[13:20:41] <maxcnc> pcw all clear now here in Germany the plasma works fine
[13:21:23] <the> maxcnc, where are you?
[13:21:30] <maxcnc> in Germany
[13:21:38] <the> wo in deutschland?
[13:21:44] <maxcnc> Zweibrücken
[13:21:54] <the> i am in muenster :-)
[13:22:05] <maxcnc> snow there
[13:22:16] <the> not yet but its cold now.
[13:22:24] <the> i think it comes soon!
[13:22:30] <maxcnc> we expect at thursday
[13:22:52] <maxcnc> but im back from 1 week in the alps boarding around in deep powder
[13:23:01] <the> yes, expect shit weather for the next 3 months.. lol
[13:23:09] <the> thats sounds nice.
[13:23:19] <maxcnc> here in the soth maybe 2weeks
[13:23:31] <maxcnc> south
[13:23:45] <the> what machine you work with?
[13:23:55] <maxcnc> todays storm went of with no action
[13:24:25] <maxcnc> 4 plasmas + foamcutters + mills
[13:25:37] <the> interesting.. what foam cutters?
[13:25:48] <maxcnc> xyuvb
[13:26:12] <the> i have a laser welder, laser engraver, fs3mg and a little emco cnc lathe..
[13:26:35] <maxcnc> Lengrave watt
[13:27:11] <maxcnc> for wood we use 2DVD burners
[13:27:20] <maxcnc> works cool
[13:27:23] <jdh> what do you laser weld?
[13:27:30] <the> nice, small parts...
[13:27:37] <maxcnc> 10euros
[13:27:46] <maxcnc> 3D printer lense conector
[13:28:45] <the> rofin performance laser welder :-)
[13:29:30] <maxcnc> i know someone who fixes this things from around here world wide action
[13:29:45] <maxcnc> he is always on the run
[13:30:01] <maxcnc> 1 month lost in china
[13:30:17] <the> the security on these machines is ridiculous...
[13:30:31] <the> you need a password or dongle for almost everything.
[13:30:43] <maxcnc> is it a arm welder or fixed with glases
[13:30:52] <the> i cross my fingers it doesnt go wrong..
[13:31:20] <maxcnc> you can shoot nice tattoos with it on your fingernail
[13:31:52] <maxcnc> at setup power
[13:32:15] <the> http://www.lrm.technology/products/laser-welding-2/performance/
[13:32:34] <the> should the desire take you :-)
[13:33:23] <maxcnc> yes its the for everyone on its own product
[13:33:37] <maxcnc> you can give avery user its wn max power
[13:33:49] <maxcnc> and set a time limit
[13:34:20] <maxcnc> 5years ago i worked in a factory that had one of this
[13:34:44] <maxcnc> lots of people wedet cool stuff beside work
[13:39:07] <maxcnc> Loetmichel2: happy new year to you i grounded almost everything at the plasma and now no error
[13:47:04] <PCW> maxcnc: you might try the new firmware if you haven't already, its more resistant to impulse noise

[14:14:04] <CaptHindsight> if you people would stop terrorizing everybody then this wouldn't be happening
[14:16:02] <CaptHindsight> _methods: you are corect the world is not just black and white, it's green, yellow red, red-orange, yellow-red-orange etc etc
[14:19:58] <_methods> hehe
[14:20:27] <_methods> deep web lol
[14:20:45] <_methods> that's where the terrorists hang out man
[14:21:36] <Tom_itx> i'll just hang out on the beach
[14:21:58] <CaptHindsight> fascist or commie beach?
[14:27:17] <CaptHindsight> in partial seriousness, a Google search might be considered a light search, including Bing, Yahoo and ask Jeeves might be a medium search
[14:30:49] <_methods> duck duck go is a full body cavity?
[14:36:53] <lair82> Good Afternoon Guys,
[14:38:21] <lair82> PCW, awhile back I was asking about my 7i49 having a 7.5 millivolt output on one of the PWGens, and how to get that to actually be zero. Is that possible?
[14:54:25] <PCW> 7.5 mV should be OK
[14:54:27] <PCW> That is with a 2000 RPM motor for example that's a 1.5 RPM velocity offset
[14:57:07] <lair82> Here is a video of a part we are running right now, more fun with the 4th Axis on '84 Cincinnati Milacron https://youtu.be/JINL4n-A4D0 as always a big Thank You to all the help getting this thing going.
[14:58:23] <cradek> sweet!
[14:59:05] <the> lair82, cool... what is the material?
[14:59:17] <cradek> it's sure squeaky
[14:59:24] <_methods> hehe the retract
[14:59:43] <lair82> It was originally about 7.2 volts, so in the drive I was able to comp out 7 mv, but it drifted up to 7.5 mv, and then the servo started drifting, so I adjusted the drive to 8 mv, and it stopped.
[15:00:05] <lair82> The material is 4340 Pre-hard
[15:00:23] <the> lair82, ok...
[15:00:24] <PetefromTn_> very nice man
[15:00:33] <PetefromTn_> what screenset is that?
[15:00:44] <PetefromTn_> and what is holding the part on the fourth axis?
[15:00:52] <_methods> id clamp
[15:00:57] <lair82> We've been back and forth with Gscreen and Gmoccapy
[15:01:05] <PCW> The drive should not be enabled when the PID loop is not closed so should never drift even with 50 MV of offset
[15:01:17] <cradek> ^^
[15:01:40] <cradek> and those adjustments aren't permanent so you can't depend on them
[15:01:57] <lair82> There are two dowel pins coming in from the back side driving it, and a tailstock pushing it
[15:02:52] <_methods> ahh
[15:03:46] <PCW> you can adjust the offset of the PWM or PID outputs but not when the analog outputs are disabled (but the drive should be disabled in this case)
[15:04:03] <PetefromTn_> thanks I was wondering how it was held on there.
[15:04:22] <lair82> I guess I have never payed attention, but are the pwgen enable out signals only true when there is a voltage command? And should I tie the servo-enable to those?
[15:06:57] <PCW> They are true when the PWM enable signal is asserted (they are common for all 6 channels) and yes the 7I49s
[15:06:59] <PCW> OPTO coupler outputs should be used to enable the drives (they are ON when enabled)
[15:08:40] <lair82> Ok, I will do some re-configuring then.
[15:09:51] <PCW> normally you would wire the PWM enable to axis.0.amp-enable-out (in HAL)
[15:10:59] <Sync> lots of air cutting :D
[15:11:12] <PetefromTn_> heh
[15:11:32] <PCW> and then use the OPTOs to enable the drives (paying attention to polarity, since backwards OPTOs will be always on)
[15:12:06] <PetefromTn_> I was not gonna say that but yeah...;) I am guilty as well of having the plunge slow on initial runs wasting spindle time but I am not making thousands of parts...yet ;)
[15:12:28] <_methods> backseat programmers
[15:12:29] <_methods> lol
[15:12:57] <PetefromTn_> I know right... you guys would probably laugh your asses off if you saw my programs run hehe
[15:13:12] <the> hi guys, on the main stock linuxcnc axis-lathe preview screen what is TLO?
[15:13:26] <PetefromTn_> tool length offset I guess?
[15:13:27] <cradek> tool (length) offset
[15:13:35] <the> thanks..
[15:14:03] <PetefromTn_> I have not ever seen the axis lathe screen in person...yet :D
[15:16:29] <the> PetefromTn_, lol... i am just getting the idea how to use it. ngcgui appears to be very useful...
[15:16:34] <lair82> PCW, so I can wire the servo-enable directly off of the ENA1- and ENA1+ on the 7i49, for the respective pwmgen I am dealing with, and enable the drive that way?
[15:16:56] <lair82> Can the optos handle 24VDC?
[15:18:28] <lair82> The program is retracting that far, because it things it is still a full round billet, not finish turned like it is, we could have modified the program, but it was already done.
[15:18:31] <PetefromTn_> yeah I have been using linuxCNC on my Cincinatti Arrow 500 VMC for a good while now but I just am getting around to doing the CNC retrofit on my Standard Modern CNC lathe.
[15:18:57] <CaptHindsight> lair82: with the proper series resistor
[15:19:00] <PetefromTn_> lair82 I figured as much looks good man and the part is BIG
[15:19:58] <lair82> That part is being run using sub routines as well, the main program is less than 100 lines long, the sub for the slot is almost 6000 lines, we just called the sub 13 times for the 13 slots.
[15:20:24] <lair82> At the corresponding angle of course
[15:20:32] <CaptHindsight> sounds like the SS I've been milling
[15:22:51] <PCW> Yes the OPTOs are fine with 24V but only 20 or so mA
[15:24:13] <CaptHindsight> what is the forward voltage of the optos?
[15:25:42] <CaptHindsight> http://www.digikey.com/en/resources/conversion-calculators/conversion-calculator-led-series-resistor might come in handy in picking resistor values for optos
[15:26:32] <the> anyone using ngcgui with a lathe?
[15:27:39] <CaptHindsight> http://homepages.which.net/~paul.hills/SpeedControl/Optos.html
[15:36:39] <the> does anyone have an idea why on the preview screen G54 shows on the opposite side of my x datum to where my home switch is?
[15:36:50] <the> using a lathe...
[15:39:18] <the> hmm.. so to explain better the home switch for x on my crosslide as at the maximum positive x which is of course not 0 where axis thinks it should be...
[15:39:58] <the> or rather where i would like it to be to stop my tool post crashing into my chuck!#
[15:40:53] <CaptHindsight> http://ledcalc.com/ here's another series resister calculator
[15:41:04] <the> when i do a G54 G0 X0 Z0 at the end of a cycle to move the tool post into a safe position to do a tool change..
[15:41:29] <_methods> sounds like you have something backwards
[15:41:33] <_methods> on x
[15:41:36] <the> yes..
[15:42:06] <_methods> posting your config might help
[15:43:20] <the> _methods, i am just looking in my .ini to see if there is anything relating to this...
[15:43:38] <the> _methods, would that be the correct place to look?
[15:44:02] <_methods> .ini i bleileve
[15:44:32] <_methods> in your axis section
[15:45:34] <the> _methods, yes, that is what i thought, looks ok...
[15:50:45] <lair82> PCW, so the pwmgen enables are all common, ( regardless of which axis is commanded, they all turn on when asserted)?
[15:59:45] <enleth> eh, my Mesa order is passing through customs now, I wonder how much those jerkasses will force me to pay
[16:04:04] <Jymmm> ONE ZILLION DOLLARS
[16:04:23] <XXCoder> thats cheap in pesos
[16:04:54] <Jymmm> XXCoder: For you, in ounces of .999999% gold bars
[16:06:43] <Tom_itx> Jymmm i c u found rue
[16:08:19] <Jymmm> Tom_itx: Yeah, got a little better idea of what he's doing, but still need more details (over time)
[16:32:10] <PCW> lair82: yes there's only one enable signal in the hardware so xxxx.pwmgen.0.enable connects to axis.0.amp-enable-out
[16:47:44] <Deejay> gn8
[16:54:55] <andypugh> My lathe conversion now has auto-oiling for the Z bearings and drive. And a tell-tale to show if the pump is working. All a bit over-elaborate, I suspect: https://picasaweb.google.com/108164504656404380542/Holbrook#6238660454335194690
[16:55:19] <andypugh> https://picasaweb.google.com/108164504656404380542/Holbrook#6238660461987316690
[16:56:44] <cradek> cool!
[16:56:54] <PetefromTn_> you probably think that is slicker than snot huh ;)
[16:57:06] <PetefromTn_> and ya know you'd be right!
[16:58:59] <andypugh> It’s an approximate copy of what was there before. The shallow trough to catch some oil bit let most of it just flow away is quite clever.
[16:59:00] <malcom2073> Nice!
[16:59:36] <malcom2073> So does that run anytime the lathe is running, and any overflow oil gets recycled back to the pump?
[17:01:10] <andypugh> Yes, there is a pump driven by the spindle that sucks oil ip the nylon pipe, through a filter and into the head. Then it runs out the drain at the bottom and back into the gearbox. It used to be directed over all the threading gears by a perforated plate, but I have rather less to lubricate.
[17:01:41] <malcom2073> I like the plate with holes thing though, that's kinda cool
[17:02:18] <andypugh> There are three holes, one goes straight back into the casting between the angular contact bearings.
[17:03:01] <andypugh> Hopefully the copper pipes won’t fall out. They are loctited _and_ swaged :-)
[17:03:39] <andypugh> Time to start on the saddle casting now.
[17:04:57] <andypugh> But not tonight.
[17:08:20] <enleth> andypugh: you're remaking the saddle too?
[17:09:04] <andypugh> No, the saddle is good, I meant the Apron, actually
[17:09:28] <andypugh> I need to swap the current gear-drive in there for another servo and a ballscrew mount.
[17:09:53] <enleth> ah, OK
[17:10:19] <enleth> so you're ridding the lathe of the normal power feed completely?
[17:15:50] <andypugh> Yes. It was a variable speed DC servo anyway, so not so big a change.
[17:24:41] <the> hi guys, anyone using ngcgui for lathe?
[17:25:35] <Akex_> andypugh: awesome !!
[17:25:48] <Akex_> You are crazy :)
[17:27:50] <the> anyone know what back tools are on a lathe? i am trying to work out if i have them...
[17:29:23] <the> if i G53 G0 x0 z0 my tool and turret would crash into my chuck...
[17:29:45] <andypugh> A conventional manual lathe has tools at the front. If your tools are on the opposite side of the workpiece to the operator, then it’s a back-tool
[17:30:15] <the> andypugh, hi, then no it isnt...
[17:30:25] <andypugh> I suggest not doing a G53 X0 Z0 then
[17:30:40] <andypugh> (I think that is true for any lathe)
[17:30:44] <the> any idea why it would home ok but not if i G53?
[17:30:59] <the> lol... i didnt.
[17:31:44] <the> just trying to learn to use ngcgui, the first cycle i tried finished with the G53 G0 x0 z0
[17:31:56] <andypugh> You might want to set home position so that the home switch is at +0.1, home is at 0, X max is 0 and X min is -150 (or whatever)
[17:31:58] <the> luckily i was paying attention :-)
[17:32:50] <the> not sure what you mean..
[17:32:53] <andypugh> I don’t actually know where G53 X0 is on my lathe.
[17:33:21] <the> hmm... ok, so its not so important if i dont use it!
[17:33:41] <the> it is shown on the axis preview screen.
[17:34:11] <andypugh> If CAM packages are going to assume that G53 X0 is all the way out, then you may need to set up the machine so that that is true.
[17:34:14] <the> and on my screen is show as if it was a backtool setup ie on the opposite side..
[17:34:42] <andypugh> Front-tool or back tool actually has no bearing on this.
[17:34:50] <PetefromTn_> I was wondering the same thing... I use G53 G0 Zo to raise the millhead after a program or toolchange right now but I don't know how I will run the lathe yet
[17:35:23] <the> i think the idea is to home the tool changer so it can do a safe tool change..
[17:35:26] <the> no?
[17:35:42] <andypugh> And I guess that your Z axis max (on the mill) is 0, and the min is -16” or something?
[17:36:04] <andypugh> the: So, set up the axis limits so that that works.
[17:36:14] <the> i have no idea why or how axis sets this up in relation to where the home switches really are..
[17:36:26] <andypugh> It’s all in the iNI file.
[17:37:04] <andypugh> Are you regretting choosing the username “the” because avery time someone uses the word the you get a beep from the client?
[17:38:12] <the> lol... i really have not got much of an idea how to use irc. my user name is thesaint but it gets abreviated to the, i was to embarassed to ask and to engrossed in playing with my lathe to find out myself...
[17:38:28] <andypugh> Axis doesn’t set anything up. You set it up when you configure the machine.
[17:39:06] <the> ok, so its in my .ini , yes but what to change it to? thanks..!
[17:40:22] <FloppyDisk> my floppydisk user name says 'it's taken' and I should login or something like that. I think when I first connect to free node w/ hexchat. dunno either.
[17:40:48] <the> all i see is the home position which would be correct.
[17:40:57] <Roguish> the: remember the docs are your friends. http://linuxcnc.org/docs/2.6/html/config/ini_config.html
[17:41:12] <Roguish> http://linuxcnc.org/docs/2.6/html/config/ini_homing.html
[17:41:23] <Roguish> http://linuxcnc.org/docs/2.6/html/config/lathe_config.html
[17:42:16] <FloppyDisk> roguish: didn't know the g18 for the plane of the lathe - thank you.
[17:42:29] <FloppyDisk> kinda cool...
[17:42:57] <andypugh> the: As I said, try home offset of + (a small number) max of 0 and min if - (the axis travel). So all positions are negative numbers, and 0 is maximum diameter
[17:44:20] <Roguish> the: I don't know squat about lathes, I just know there is a ton of info in the docs. the docs have been worked on really hard over the last few years.
[17:46:35] <_methods> the: did you ever post your config?
[17:46:48] <_methods> really much easier to help troubleshoot if you help
[17:47:32] <_methods> pastebin is your friend
[17:47:42] <enleth> FloppyDisk: that means someone registered this nickname with NickServ and will probably kick you out of the network as soon as they return (unless they're not using this nickname anymore, the registration expires after some time)
[17:48:25] <andypugh> I always get the same message. Then it sort-of goes “Ah, OK, it’s you with the nick registered, that’s different"
[17:48:25] <FloppyDisk> enleth: thanks - I figured that might happen, waiting to be kicked out...
[17:48:28] <_methods> pastebin and imgur make things much clearer usually
[17:49:33] <enleth> FloppyDisk: FYI a nickname owner can ask NickServ to kick out anyone using their nick without proper credentials
[17:49:35] <JT-Shop> the: back tools are on the opposite side of the spindle from you, if the tools are on the same side of the spindle as you then you have front tools
[17:50:59] <rob_h> what if you have turret on both sides
[17:52:14] <the> _methods, http://pastebin.com/iKPqqP1P - my .ini - seems to be working.
[17:53:15] <andypugh> rob_h: The you need to give negative diameters to one of them, but if you fo that and have the tool offsets correc,t it all works fine.
[17:54:00] <the> JT-Shop, i have front tools then... trying to work out why G54 is showing at the top left of my preview in axis. when i run your od.ngc cycle the end line is G54 G0 x0 z0 which would crash my turret...
[17:55:52] <andypugh> the: This is the X axis of my lathe, note how the max is small and the min is negative. http://pastebin.com/i61p8qLH
[17:56:25] <JT-Shop> the: where do you home to? I home to far right Z and near me X
[17:57:04] <andypugh> Near-me X. Far left Z. (I have a tailstock, so towards the chuck is actually safer)
[17:57:21] <JT-Shop> mine is a chucker no tail stock
[17:58:06] <andypugh> The lathe I am working on now is going ro home absolute, ie with no movement of Z, or only half a turn of the leadscrew, depending on what works.
[17:58:11] <JT-Shop> the: the G53 move only makes sense if you home where I do
[17:58:19] <JT-Shop> cool
[18:00:50] <the> I home far left near me, bottom of the slant on my crosslide...
[18:01:19] <andypugh> Is your lath a huge 40” or a tiny 40mm?
[18:01:28] <the> tiny...
[18:01:41] <the> 60mm motion on the cross slide..
[18:01:43] <JT-Shop> then you need to change the G53 move to move to a safe location, I use G53 so there is never an offset issue
[18:02:17] <the> JT-Shop, yes, learning lots :-)
[18:02:35] <andypugh> JT-Shop: Safer to change the limits, lots of CAM software assumes G53 X0 is all the way out.
[18:02:36] <the> andypugh, looking at your paste, thanks..
[18:02:57] <the> andypugh, trying to understand and do that now...
[18:15:14] <the> andypugh, axis preview g54 point now looks correct but i cant get it to home, get message exceeded positive soft limit on joint 0... thanks!
[18:16:01] <the> my MIN_LIMIT = -45 and my MAX_LIMIT = 0...
[18:17:21] <JT-Shop> you might need a bit of max limit like 0.1
[18:20:05] <the> JT-Shop, hmm.. still the same, no go.
[18:21:29] <Roguish> the: are you homing in the right direction?
[18:23:37] <the> Roguish, yes, just doesnt like the new min max limits...
[18:23:56] <the> but the new limits do make G54 show up in the right place...
[18:24:53] <JT-Shop> G54?
[18:27:06] <the> G53, sorry...
[18:27:50] <_methods> doesn't linuxcnc make g53/g54 the same by default?
[18:28:05] <_methods> when you home it sets that as g54 correct?
[18:29:38] <the> hi, i was getting confused myself, on my axis screen in the preview it shows G54, this it would appear is indeed the same as G53 - someone correct me if i am wrong...
[18:29:43] * JT-Shop thinks he needs to further subdivide the crimp on terminal collection
[18:30:21] <_methods> you can reset g54 to whatever
[18:30:49] <_methods> but i think they default when you home
[18:31:00] <_methods> to home position
[18:31:01] <JT-Shop> the: G53 is the machine coordinates
[18:31:08] <_methods> yes
[18:31:22] <_methods> but when you home i believe lcnc sets both g53 and g54
[18:31:28] <JT-Shop> G54 - G59.4 is coordinate systems you can apply offsets to
[18:31:31] <_methods> to the same coordinates
[18:31:54] <JT-Shop> not really, if you have an offset from before in G54 it is still there
[18:32:05] <_methods> ahhhh
[18:32:14] <_methods> i did not know that
[18:32:29] <_methods> even when your first fire up a machine and home it?
[18:32:35] <JT-Shop> a good bed time story is the important user concepts in the manual
[18:32:52] <JT-Shop> offsets are stored in a file...
[18:33:00] <_methods> well alrighty then
[18:33:27] <_methods> good to know
[18:36:47] <JT-Shop> that's another reason a good preamble is needed
[18:40:56] <Tom_itx> JT-Shop, your new 'bike' https://duckduckgo.com/?q=swincar&iax=1&ia=images
[18:41:38] <enleth> andypugh: did you have that gearbox casting made commercially or somehow made it yourself?
[18:42:40] <enleth> Tom_itx: is the kinda-sorta 30's vintage car look intentional?
[18:42:55] <JT-Shop> I could have used that today lol
[18:45:00] <malcom2073> Tom_itx: I've seen that before, it's nuts
[18:50:43] <_methods> for people that love ditches
[18:53:05] <the> aaahh! cant get it to work...
[18:55:00] <andypugh> enleth: I paid a foundry to make the casting from my own patterns.
[18:55:17] <the> JT-Shop, your od.ngc - what is final cut?
[18:56:05] <andypugh> the: I can’t remember what the home_offset means, but that will be your problem. Is it a shared home/limit switch?
[18:56:11] <the> JT-Shop, the cycle appears to work for me but stops at around half the required depth of final diameter...
[18:56:15] <JT-Shop> depth of last cut IIRC
[18:56:53] <the> andypugh, yes, only one limit swich on the z and one on the cross slide...
[18:57:29] <andypugh> You need the switch to be outside your axis limits then. So yo can’t jog on to it.
[18:57:44] <the> JT-Shop, that is what i thought. i cant get it to cut the full depth - any idea? does a certain number of passes and stops with the motor still going...
[18:58:42] <the> andypugh, ie a -minus value also?
[18:59:10] <andypugh> I can’t remember. It’s ages since I set up a new machine.
[18:59:27] <the> andypugh, i will try... cheers.
[19:00:57] <andypugh> Do you get the message after homing is complete but before you move? That indicates that the move-to-home isn’t moving off the switch.
[19:02:36] <the> andypugh, i get the message after homing is complete - everything moves in exactly the same way as it did originally.
[19:03:58] <andypugh> Your home position needs to be somewhere clear of the switch. Is your final homing move off of the switch or on to the switch?
[19:04:32] <andypugh> Have you read the homing page?
[19:05:54] <andypugh> I am curious to see what this goes for, I intend to sell my home-converted mill/lathe at some point.
[19:05:57] <andypugh> http://www.ebay.co.uk/itm/151936433454
[19:06:11] <the> final homing move is off the switch. it finds the switch then trys to move much further than the possible movement of the cross slide...
[19:07:10] <andypugh> What’s your home position?
[19:07:44] <the> working - 40
[19:07:53] <the> not minus
[19:08:10] <andypugh> That’s all the way in
[19:08:21] <the> x, HOME = 40.0
[19:08:29] <andypugh> You don’t have a 40 any more...
[19:08:34] <the> at the very beginning of its travel...
[19:08:35] <archivist> andypugh, I had one of those mills as a manual, its junk as a mill, but a reasonable grill
[19:08:38] <archivist> drill
[19:09:12] <andypugh> If your max is 0 and your min is 40, then it can’t move to a home position of 40, can it?
[19:09:21] <andypugh> Sorry, min is -40
[19:10:56] <andypugh> The HOME_POSITION has to be somewhere between Min and Max
[19:11:00] <archivist> the round column is the main error in design
[19:11:41] <andypugh> I am not planning on bidding, I am just wondering if anyone actually pays money for scruffy home-conversions.
[19:11:57] <andypugh> (I think mine is a little better-looking than that one)
[19:12:10] <archivist> I would never expect you to get one of those :)
[19:12:39] <JT-Shop> you guys are burning the midnight oil tonight
[19:12:42] <archivist> I think its reserve is too high
[19:13:12] <andypugh> JT-Shop: It’s only a little past midnight
[19:13:29] <JT-Shop> I stayed up to midnight once
[19:13:39] <JT-Shop> well maybe twice
[19:13:40] <andypugh> archivist: Hmm, yes “Reserve not met”
[19:14:11] <andypugh> Not even on ballscrews.
[19:15:28] <andypugh> This is mine: https://picasaweb.google.com/108164504656404380542/CNCUnsorted#5611904480713910226 I have certainly become more ambitious in my conversions since that. Mainly my budget is about an order of magnitude higher.
[19:15:50] <archivist> andypugh, yet no bids yet on http://www.ebay.co.uk/itm/Adcock-Shipley-2AG-Horizontal-Milling-Machine-/181986608684
[19:16:19] <archivist> and no silly reserve
[19:16:25] <andypugh> Folk don’t realise that Horizontals are useful
[19:16:56] <archivist> and that is a good lump of iron
[19:17:37] <_methods> i'd rather have a horizontal personally
[19:17:58] <andypugh> Another problem for many folk. They can’t see how they would move it, or where they could put it. The Mach3 device would sit in a wood-floored shed. The Adcock and Shipley would fall through the floor of a shed.
[19:18:17] <andypugh> _methods: Having both is good.
[19:18:25] <_methods> oh of course
[19:18:36] <_methods> but if i had to pick one or the other i'd pick the horizontal
[19:19:17] <andypugh> _methods: I find the horizontal head useful for stuff that is way too big for the mill, like this: https://picasaweb.google.com/108164504656404380542/Holbrook#6231236737028424114
[19:19:34] <_methods> way more versatile
[19:19:41] <andypugh> I mean having a single machine with both heads
[19:19:43] <_methods> you just have to be more creative with your setups
[19:20:35] <andypugh> _methods: This is the same machine: https://picasaweb.google.com/108164504656404380542/Holbrook#6230479153726904034
[19:21:17] <_methods> yeah nice machine
[19:21:50] <_methods> i'm tryin to find a nice hardinge tm-um
[19:21:57] <_methods> for a reasonable price lol
[19:22:03] <archivist> I was abusing mine a bit http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_06_15_Adcock_Shipley/IMG_1249.JPG
[19:22:39] * malcom2073 kicks archivist's internet pipe
[19:22:39] <malcom2073> :P
[19:22:58] <_methods> now that's what i was talking about
[19:23:02] <_methods> gettin creative lol
[19:24:06] <_methods> some smartass put libreoffice in the lcnc iso
[19:24:26] <_methods> has that always been in there lol
[19:24:31] <andypugh> archivist: It ought to be trivial to fasten a high-speed Chinese spindle to the overarm for for engraving etc.
[19:25:06] <andypugh> _methods: It’s part of the Debian LiveCD. So more a case of the pacckage builder not removing it.
[19:25:25] <andypugh> You can remove it if you want. But do _not_ remove the calendar thingy.
[19:25:33] <_methods> hahah ok
[19:25:38] <_methods> i'll leave it i'm not hurting for space
[19:25:52] <_methods> i was just curious what was taking my install so long
[19:26:34] <andypugh> For some reason the entire GUI has a dependency on the calendar. If you uninstall that then do an autoremove you lose X ans GTK and have a text-only command-line machine.
[19:26:43] <andypugh> Don’t ask me how I know.
[19:26:59] <_methods> haha i think i remember you having that issue a month ago or so
[19:43:39] <the> taking the opportunity to make some bedtime reading...
[19:44:05] <the> and i think tomorrow i have to fix my nick, the just doesnt cut it...
[19:44:38] <andypugh> I think you just have to type /nick newname
[19:44:55] <thesaint> lol..
[19:45:00] <Akex_> +1
[19:45:10] <thesaint> never did like irc...
[19:45:51] <thesaint> andypugh, didnt get it working but learnt lots, thanks for the help..
[19:46:15] <andypugh> You will get there. You just need to read, study and inwardly digest the homing manpage
[19:46:32] <Akex_> Andy How you choose the speed on your lathe ? With linuxcnc ?
[19:46:47] <Akex_> Spindle speed
[19:47:12] <andypugh> Which lathe?
[19:47:53] <Akex_> Maybe Is not the good words (spindle)
[19:48:15] <Akex_> The last picture
[19:48:47] <Akex_> Holbrook
[19:49:19] <andypugh> Ah, that is done with LinuxCNC, yes. There is only one VFD that either controls the mill spindle or the lathe spoindle. A relay swaps between the two (hard-coded in the HAL file for lathe or mill mode)
[19:49:20] <Akex_> I see you put a vfd or similar
[19:49:33] <andypugh> Ah, no, wait, the Holbrook?
[19:49:43] <thesaint> andypugh, going to read it now.... cheers.
[19:49:43] <andypugh> That is a work in progress.
[19:49:50] <Akex_> Yes
[19:50:23] <Akex_> Ok and on this lathe there are a gear box ?
[19:50:34] <andypugh> There is a 3hp motor in the base, with a variator, a gearbox _and_ a VFD. I still need to decide how the speed will be controlled. I _could_ put a servo on the variator.
[19:51:32] <andypugh> The motor in some of the photos is the Z servo, though it looks big enough to drive a spindle.
[19:51:44] <andypugh> (1kW)
[19:51:59] <Akex_> Ok, for you what Is a power for a good servo ?
[19:52:16] <Akex_> Power needed
[19:52:24] <andypugh> It depends on the application.
[19:53:00] <Akex_> The good answer ;)
[19:53:49] <Akex_> And you, for your lathe ?
[19:54:18] <andypugh> My stepper lathe is about 50W per axis, and works fine. The Holbrook will be 1kW on Z and 600W on X, and I fully expect not to be working the motors even slightly hard.
[19:54:45] <andypugh> I am largely using motors that I had lying about that turned up cheap on eBay
[19:55:03] <Akex_> I speak for spindle
[19:56:19] <andypugh> 1.0kW is OK on my stepper lathe. I expect the 2.2kW on the Holbrook to be better. Commercial CNC lathes tend to be 7kW or more.
[19:56:46] <Akex_> I have a lathe but i don t know if i install linuxcnc or just a dro
[19:56:48] <andypugh> Lots of mid-sized manual lathes like the Myford are 1hp
[19:57:14] <Akex_> 7kw Is not cheap no ?
[19:57:37] <andypugh> No, and is difficult on a domestic power supply.
[19:58:05] <Akex_> I have 32A and 380v
[19:58:38] <andypugh> Anyway, I have to log off now. But it sounds like you can run a proper industrial machine.
[20:10:29] <malcom2073> Wolf_: http://www.cabinfeverexpo.com/
[20:10:58] <Wolf_> oo
[20:13:51] <malcom2073> Their auction is pretty cool on Friday
[20:56:12] <PetefromTn_> https://www.youtube.com/watch?v=KaOC9danxNo&spfreload=10 Very very cool tribute
