[00:04:46] theorb is now known as theorbtwo
[00:05:52] <JT-Shop> yea, almost no shadows
[00:06:40] <JT-Shop> Danimal_garage: are your walls painted?
[00:07:31] <Danimal_garage> not yet
[00:07:38] <Danimal_garage> some are
[00:07:41] <Danimal_garage> not all
[00:07:56] <JT-Shop> I was amazed at how much that made a difference
[00:08:30] -!- boot|necklad [boot|necklad!~tmgcleave@host-78-151-63-214.as13285.net] has joined #emc
[00:08:54] <Danimal_garage> i used to have no drywall, just that made a big difference
[00:09:02] <Danimal_garage> light grey vs bare lumber
[00:09:13] <JT-Shop> yea, that is pretty white already
[00:10:18] <andypugh> I think there is a bug with extents in Axis.
[00:10:27] <JT-Shop> I'm really stoked to be this far... can't wait to move the plasma cutter in and get a bit organized
[00:10:37] <JT-Shop> andypugh: have you found something?
[00:10:51] -!- bootnecklad has quit [Ping timeout: 258 seconds]
[00:11:34] <Danimal_garage> is the lathe and vmc in already?
[00:11:46] <JT-Shop> no, they will be last in
[00:12:05] <JT-Shop> lathe then vmc after all else is done
[00:12:27] <JT-Shop> I'm hoping for a bit of a break in temperatures for the outside part of the move
[00:13:15] <JT-Shop> I just put my desk down on the floor Friday :)
[00:13:32] <andypugh> Well, running the same code in 2.4.3 and 2.6 with the "exceeds extents" edited to _always_ print, and to report the limits.. 2.6 says the max is 6.55 and the program goes to 7.937 in Y. 2.4.3 says that the max is 6.55 and the program goes to 4.499 in Y. Moving the cutter to the highest Z cut shows that 4.499 is correct.
[00:14:40] <andypugh> Guess what the Z tool length is?
[00:14:49] <JT-Shop> dunno
[00:14:56] <JT-Shop> the difference?
[00:14:59] <andypugh> Yup
[00:15:10] <andypugh> 3.438
[00:15:41] <JT-Shop> so the Z tool length is getting added to the Y?
[00:15:47] <andypugh> So it appears.
[00:16:00] <IG-garage> bugh, 7:12 AM, need to go to my new work.
[00:16:06] <JT-Shop> that is something concrete to chew on
[00:16:37] <JT-Shop> funny your on the opposite side of the earth from me
[00:16:48] <JT-Shop> it's 7:17pm here
[00:17:20] <JT-Shop> now to finger out where it is being added...
[00:17:30] <andypugh> I think I can guess.
[00:17:46] <JT-Shop> that's more than I can
[00:19:41] * JT-Shop heads inside as I'm the chef of the day

[01:00:49] <andypugh> crossed-rollers are better.
[01:02:14] <Danimal_garage> Perhaps, but the quote from the movie isn't "It's all crossed-roller bearings these days..."
[01:02:44] <andypugh> I didn't recognise it as a film quote.

[03:48:02] <Connor> okay, so, my new vise came with these little square slugs and screws.. Looks like your suppose to put them on the bottom of the vise, and it's suppose to keep the vise square with the table.. only problem is, they don't fit the groves in the vise, or the table.. they're a bit too big.. is this normal ?
[03:48:12] <Connor> Does anyone use those things?
[03:54:39] <Sairon> yeah, normal
[03:54:44] <Sairon> where'd you get the vice?
[03:54:50] <Sairon> er, vise

[03:57:02] <Sairon> oh, ok
[03:57:08] <Sairon> hmpf. never used their stuff
[03:57:45] <Connor> It's a cheaper one.. $89.00.. Looks okay.. jaws look good.. I just wasn't sure if that was normal.. and, not sure how many people bother to use them..
[04:00:09] <Sairon> oh, wow, $89?
[04:00:21] <Connor> yea
[04:00:33] <Sairon> naw, it seems i've never had a vise that they fit right
[04:00:50] <Sairon> i've considered grinding them to the right size
[04:00:53] <Sairon> but, eh
[04:01:30] <Tom_itx> you've never gotten a kurt either
[04:01:40] <Connor> http://www.shars.com/products/view/62/5x5x112quot_Lock_Down_Precision_Milling_Machine_Vise
[04:01:55] <Sairon> it's true that i've never gotten a kurt

[04:04:14] <Tom_itx> defacto standard
[04:04:53] <Sairon> true, true
[04:05:01] <Connor> Yes, very nice vice.. WAAAY out of my price range.. WAY out of it ..
[04:05:05] <Sairon> i took the balance and went with another brand
[04:05:18] <Sairon> because i needed the budget room for other stuff
[04:05:32] <Sairon> i'd like to do a side-by-side comparison some time
[04:06:10] <Sairon> damn
[04:06:18] <Tom_itx> we had a 6 or 8" on every mill in the shop and sometimes 2 or 3
[04:06:22] <Sairon> just looked at the details on one of their vices

[04:07:17] <Sairon> there's a place up the road from me
[04:07:21] <Sairon> where you can rent machine time
[04:07:28] <Sairon> but you have to bring all your own stuff
[04:07:35] <Sairon> i.e. vises, tooling, even collets
[04:07:55] <Sairon> i think finding the right vise is going to be one of my first steps

[10:13:56] <IG-garage> heh, i have seen some Russian cnc lathe. From CNC there are only keys on the keyboard, and lack of any gears. Some steppers 200x200x400 millimeters. Rigid frame.
[10:14:39] <IG-garage> Other CNC machines are very sophisticated, have multiple axes.

[10:17:44] <Fox_Muldr> anyone know why emc uses massive cpu load until it is unusable when using "repeat" instructions within g-code? when i flatten the loop to a sequence it needs no cpu power at all. but the code gets longer :(

[10:33:16] <elmo40> pastebin your code. someone will help troubleshoot
[10:40:40] <jthornton> endless loop will do it
[10:45:33] <Fox_Muldr> it is only a loop with 5 iterations
[10:46:06] <IG-garage> Technologists have said they use Unigraphics for this sophisticated mill. And I will download demo version and learn it.
[10:48:38] <Fox_Muldr> here is the loop: pastebin.com/cermayu0
[10:49:09] <Fox_Muldr> it is a simple automatic probe measuring sequence for 5 tools
[10:49:27] <Fox_Muldr> the comments are in german but the code is very simple
[10:51:10] <Fox_Muldr> when i expand the code and copy the looping code five times in a row it needs no cpu power at all
[11:12:42] <jthornton> are you calling this from another file?

[11:15:57] <Fox_Muldr> i'm loading it directly from emc. before the pasted code are a few linew which set the reference tool into var #1000 which i didn't paste.
[11:16:22] <Fox_Muldr> but the problem lies within the repeat statement
[11:18:05] <jthornton> can you paste the whole file?
[11:18:12] <Fox_Muldr> ok
[11:20:07] <sumpfralle> und was sagst du zu meinem Vorschlag mit dem uni-rechner?
[11:20:23] <sumpfralle> sorry - ignore this ...
[11:20:45] <Fox_Muldr> pastebin.com/VwNAmK57
[11:20:53] <Fox_Muldr> the complete code
[11:25:44] <Fox_Muldr> tool 1 is the reference tool. and all other tools should get the length offset compared to tool 1. i already used the exüanded code version to measure the tools without problems
[11:25:46] <jthornton> Parameters #1 - #30 are local to the subroutine so change the numbered parameters to a number above 30
[11:26:03] <jthornton> otherwise you have an endless loop
[11:26:28] <jthornton> or use even better named parameters
[11:26:30] <Fox_Muldr> ok, i try it with higher numbers for the vars
[11:26:46] <jthornton> http://www.linuxcnc.org/docview/html/gcode_main.html#cha:O-Codes
[11:26:50] <Fox_Muldr> is it possible to use #var1 as var names?

[11:52:49] <jthornton> yw
[11:53:56] <Tom_itx> how do you describe a probe pin in hal?
[11:54:32] <jthornton> do you mean what do you connect it to?
[11:54:39] <Tom_itx> yes
[11:55:00] <jthornton> motion.probe-input
[11:55:02] <Fox_Muldr> i connected motion-probe-input to a free parallelport pin
[11:55:22] <Fox_Muldr> ehm motion.probe-input
[11:55:30] <Tom_itx> ok
[11:56:04] <Tom_itx> do you need to add something to the servo thread to enable it?
[11:56:12] <jthornton> http://www.linuxcnc.org/docview/html/config_emc2hal.html
[11:56:23] <jthornton> no, motion is all ready there
[11:56:48] <Tom_itx> ok, i may test it later today
[11:56:51] <jthornton> start axis and use show hal configuration and browse the motion group
[11:56:57] <Tom_itx> i will
[11:57:24] <jthornton> so you might do something like net probe-in paraport... motion.probe-input
[11:57:45] <Tom_itx> it'll go into the 7i43
[11:58:03] * jthornton thinks there should be a probe example in the manual
[11:58:09] * Tom_itx agrees
[11:58:20] <jthornton> yea, I just used the paraport as an example
[11:58:28] <Tom_itx> i know, i'll get it
[11:58:50] <jthornton> did you see the latest photos of the shop?
[11:58:55] <Tom_itx> not sure
[11:59:15] <jthornton> http://gnipsel.com/shop/inside/inside.xhtml
[11:59:23] <jthornton> just loaded them up
[11:59:27] <jthornton> last two
[11:59:35] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/emc/probe_index.php
[11:59:38] <Tom_itx> nearly ready to test
[11:59:56] <jthornton> nice
[12:00:02] <jthornton> you get a probe tip yet?

[12:03:43] <Tom_itx> i need to find another one somewhere
[12:03:58] <jthornton> got this one from the mcmaster carr salesman
[12:04:08] <jthornton> real nice and thick plastic coated
[12:04:22] <Tom_itx> i have a couple but they're getting worn
[12:10:11] <archivist> for fun today made an annular shim for the chuck on the southbend there is about 6 thou clearance at the moment, I wondered why it was never concentric
[12:10:49] <archivist> turned a 3 thou wall tube 2 5" ish dia
[12:25:35] <jthornton> did you support the od while turning the id or something like that?
[12:26:09] <archivist> only buy the solid still in the chuck
[12:26:12] <archivist> by
[12:26:24] <jthornton> wow
[12:26:47] <archivist> was delicate :)
[12:28:23] <archivist> measuring the od was not easy when it got springy, now I have to thing of fitting method, eg loctite/glue/epoxy

[15:21:12] <jdhNC> I've got some systems with single channel giga-sample boards for ultrasonic data collection. Nifty boards, but incredibly expensive.
[15:28:00] <tom3p> i used the LTC1298 to sample analog data on a 10uS thread. worked fine with test pot but getting weird result with real signal. http://www.wallacecompany.com/machine_shop/EMC2/serial_adc/
[15:28:00] <tom3p> The signal should be a 100uS on 200 uS off but halscope shows 10>m<Sec. looks like i get out the Tek DSO to looksee.
[15:29:05] <pcw_home> Aliasing...
[15:29:33] <tom3p> dunno what that means but think its the 'weirdness' typical of digital smapling?
[15:29:39] <tom3p> sampling
[15:30:25] <tom3p> wikipedia agreess 'weirdness'
[15:30:55] <pcw_home> Basically means you are not sampling fast enough to re-construct the waveform
[15:30:59] <tom3p> so dual trace real scope may help, thx
[15:31:58] <tom3p> yeah, i get that its due to rate, still dont really grok what I see
[15:32:41] <tom3p> i changed the halscope thread ( the rate of sampling ) and got wildly different traces
[15:33:01] <tom3p> hmm maybe a real analog scope

[16:39:25] <anonimasu> well they are trying to fix that so i gotta ship stuff back to them now, and wait for them to send me a new one if they cant fix that then im sending everything back
[16:39:44] <anonimasu> with that dspic I could possibly interpolate x4
[16:40:03] <anonimasu> 16384 counts/rev
[16:40:34] <anonimasu> that turns out to 65536 counts/rev in quadrature
[16:41:03] <anonimasu> 0.000076299mm per count..
[16:41:31] <syyl> thats pretty precise ;)
[16:41:33] <anonimasu> allowing for jitter +/-10 counts that 0.007
[16:41:47] <anonimasu> mm
[16:42:03] <anonimasu> indeed, that fits the target of what I want

[16:43:00] <anonimasu> 0.00000381mm per count..

[16:43:12] <syyl> that are many zeroes
[16:43:29] boot|necklad is now known as bootnecklad

[16:43:50] <syyl> so the lathe will never move ;)

[16:45:43] <syyl> or you have to set the deadband relative high

[16:46:13] <syyl> friend has sony linear scales on his emc maho700
[16:46:25] <anonimasu> max error over one period is 2µm for the less precise ones(if i remember it correctly)

[17:25:13] <L84Supper> start paving the roads with the bodies of bankers?
[17:25:29] <syyl> band foundation for a road
[17:25:51] <L84Supper> maybe just for decoration
[17:26:07] <syyl> you want to scare the hell out of the people?
[17:26:16] <syyl> :D
[17:26:17] <IchGuckLive> republicans are good if the econemy is high but not when 99% of the people are figting for the Living standard
[17:26:26] <L84Supper> it's been proven to work here
[17:26:36] <alex4nder> IchGuckLive: gun parts are also selling well
[17:26:53] <alex4nder> : |
[17:26:58] <IchGuckLive> alex4nder: Agree B)
[17:27:42] <alex4nder> everyone with a reasonably sized CNC mill and the right FFL/SOT paperwork is making AR-15 lower receivers.
[17:28:00] <IchGuckLive> if people live together and work togeter for a better future is better then fighting your naigbour for your own plesend

[17:32:57] <L84Supper> few kilo loads, max accel/decel 1-2G, few micron accuracy
[17:35:16] <L84Supper> syyl: is anyone besides the CNC manufacturers selling linear parts big and tough enough for machine tool applications?

[19:21:02] <syyl> does emc2 support pwm inputs?
[19:22:12] <cradek> syyl: that's not enough details to answer. please say what you are trying to do.
[19:22:18] <syyl> hmm
[19:22:43] <syyl> i want to connect a potentiometer for feed overide to my mesa5i20
[19:23:03] <cradek> you should use an encoder for feed override, so it interacts correctly with the onscreen controls etc
[19:23:12] <syyl> as it doesnt have analog inputs, i would go the way via a analog <-> pwm converter
[19:23:43] <cradek> halui has "counts" inputs for all the kinds of overrides, and can be set up to change by a certain percentage for each encoder count
[19:24:10] <syyl> so a "static" value, as with a potentiometer would be problematic?
[19:24:24] <cradek> yes
[19:24:35] <syyl> hmm
[19:24:43] <syyl> with a encoder it would be dead simple Oo
[19:24:45] -!- cncbasher has quit [Remote host closed the connection]
[19:24:48] <cradek> with emc, you can have many user interfaces, and they'll interact correctly if you don't use a static value like that
[19:24:58] <syyl> every click as a in/decrease of feed
[19:25:13] <cradek> typically - one user interface is onscreen (like AXIS), the other is made of your knobs/wheels (like halui)
[19:25:22] <cradek> you want them to be able to cooperate

[19:25:43] <cradek> yes that's right, every click changes it 1% or 5% or whatever you want
