[00:57:25] <alex4nder> hey
[01:58:46] <DJ9DJ> moin
[02:34:44] <mazafaka> ssi: cover the belt with something on that bandsaw
[05:54:14] <jthornton> I would assume when he assembles it he will put the covers on
[06:26:02] <joe9> ssi, you have this in your garage?
[07:31:12] <archivist> APT book arrived \0/
[07:39:31] <ssi> joe9: yeah
[07:39:57] <ssi> and MAYBE I'll put the covers on the bandsaw belts... :D
[07:40:16] <jthornton> LOL
[07:42:14] <ssi> i've never been the biggest believer in safety gear
[07:42:14] <ssi> heheh
[07:44:33] <ssi> I can't wait toget the HNC running
[07:44:36] <ssi> super excited :D
[07:44:45] <archivist> what is this safety you speak of :)
[07:46:02] <ssi> it's this thing tool manufacturers always say whenever they put a stupid feature on a machine that gets in the way
[07:50:11] <archivist> hiding the new control in the old HNC control would give ample opportunity for lotso blinkenlightz
[07:50:18] <ssi> that's my plan
[07:50:33] <ssi> I can even reuse a lot of the lighted buttons and toggle/rotary switches
[07:51:04] <ssi> http://sphotos.xx.fbcdn.net/hphotos-ash4/421210_807148396692_71107655_35455822_1156121393_n.jpg
[07:51:28] <ssi> http://sphotos.xx.fbcdn.net/hphotos-ash4/428021_807114963692_71107655_35455758_1526283375_n.jpg
[07:52:04] <ssi> my goal is to lay out a new panel and cnc plasma cut it
[07:52:19] <ssi> and replace the U-stor memory unit with a keyboard tray
[07:52:35] <jdhnc> need an avr or something to run the nixies via serial
[07:52:55] <ssi> yea I haven't decided if I want to try to use the nixies as a DRO on the machine
[07:53:03] <ssi> or scavenge them and make a desk clock for work
[07:53:13] <jdhnc> everyone does that
[07:53:25] <ssi> I know
[07:53:28] <ssi> got a better idea? :D
[07:53:45] <jdhnc> DRO, as GE intended.
[07:53:54] <ssi> it actually wasn't a DRO on this machine
[07:54:05] <ssi> left side is tool offset display, right side is MDI interface
[07:54:29] <jdhnc> that wouldn't be very interesting
[07:55:15] <ssi> I agree!
[07:55:35] <jdhnc> 14 char scrolling #LinuxCNC display
[07:57:31] <ssi> the possibilities are endless :D
[07:57:46] <ssi> I dunno, I likely won't leave them in there just cause they take up a lot of space on an already small panel
[07:57:55] <ssi> I'm hoping I can fit everything I want hardware wise into that one black panel
[07:57:59] <ssi> since it's its own little door
[07:58:43] <ssi> I wish I could find someone with a tape punch
[07:58:52] <ssi> I'd really like to write some programs to run on the original control before I dismantle it
[08:21:06] <djdelorie> ssi: my cousin is missing some fingers because of an uncovered cable pulley :-P
[08:25:16] <jdhnc> ouch... but the uncovered thing was only a part of the problem.
[08:29:56] <djdelorie> <enlightenment> so, looking at various graphs of stopping time vs RPM and applied power, it dawned on me that there are TWO inertias I have to overcome. First, the mechanical intertia, but second, also the magnetic inertia in the coils! </enlightenment>
[08:31:44] <djdelorie> that explains all the "I need to predict the current" PID loops...
[08:53:33] <theos> hi
[08:54:09] <theos> has anyone tried running linuxcnc through expanion port 3?
[08:54:23] <JT-Shop> expansion port 3?
[08:54:26] <theos> expansion*
[08:54:29] <JT-Shop> what is that?
[08:54:45] <theos> yes HP's proprietary port for docking stations/port replicators
[08:55:01] <JT-Shop> ah laptop
[08:55:12] <theos> the docking station that is attached to the port provides a parallel port
[09:01:23] <mazafaka> theos: you think the laptop itself will be allright during its work with RTAI ? What if it heats up too much?
[09:02:00] <theos> mazafaka why will it heat up too much? :)
[09:02:01] <ssi> JT-Shop: you familiar with the little setup arbor tools that go with the hardinge lathes?
[09:02:16] <ssi> http://www.ebay.com/itm/ws/eBayISAPI.dll?ViewItem&item=170794428592&ssPageName=ADME:B:WNA:US:1123
[09:02:30] <ssi> like that one, and there's another one that measures off the bed and has a little swinging cap
[09:02:57] <mazafaka> theos: because ACPI functions are turned off
[09:03:04] <JT-Shop> never seen one before is that for setting tool height?
[09:03:08] <ssi> yea I think so
[09:03:14] <ssi> I'm trying to get an idea of how exactly they're used
[09:03:15] <JT-Shop> I use a level thingy
[09:03:15] <ssi> I have the other one
[09:03:20] <ssi> wondering if I should get this one too
[09:03:30] <JT-Shop> let me see if I can find a link to it
[09:03:58] <JT-Shop> http://www.ebay.com/itm/02-Pro-Lathe-Gage-tool-insert-cutter-setting-level-center-height-setter-Atlas-/260969610719?pt=LH_DefaultDomain_0&hash=item3cc3003ddf
[09:04:00] <mazafaka> ssi: For WFL, we have a tool measuring thingie with monitor and something
[09:04:08] <theos> mazafaka i also have an old desktop. intel 440bx. will that work? P3 450mhz. 64mb ram :D
[09:04:11] <JT-Shop> owo on sale too
[09:04:20] <ssi> yea that's probably more useful at the end of the day :)
[09:04:47] <ssi> also, I need to get some step chuck collets
[09:04:58] <ssi> the guy I bought the lathe from had a pile of them, but he sorta talked me out of buying them
[09:04:59] <mazafaka> theos: anyway, try to be sure laptop will work OK
[09:05:12] <ssi> now I have a small production contract that has just come up for making 2" x 2-3/8" parts
[09:05:13] <theos> mazafaka thanks
[09:05:16] <ssi> and a 2" step chuck would be really nice
[09:05:31] <JT-Shop> step chuck?
[09:05:47] <theos> mazafaka btw what would you recommend?
[09:05:50] <ssi> http://www.amazon.com/5CC-3-5C-Chuck-Clutch-Collet/dp/B0007Q3G6W
[09:06:06] <ssi> they have a closer ring that seats on the spindle nose
[09:06:11] <ssi> the taper on yours, the threads on mine
[09:06:14] <JT-Shop> ah ok, yea I have a few of them
[09:06:37] <JT-Shop> the ones with the taper ring on the spindle nose are stronger
[09:06:48] <ssi> maybe so
[09:06:53] <ssi> but mine's threaded, so I get what I get
[09:07:39] <JT-Shop> the spindle is threaded?
[09:07:43] <ssi> yeah
[09:08:13] <ssi> yours has that 4 degree taper on the outside of the nose
[09:08:16] <ssi> mine is straight with a thread
[09:08:17] <JT-Shop> mine is a 16c collet and I can mount a normal chuck on it as well
[09:08:26] <ssi> and mine's 5c rather than 16c
[09:09:16] <ssi> http://www.shophardinge.com/product.aspx?partNo=14230000000000
[09:09:20] <JT-Shop> I make some 2 1/4" parts on mine from time to time
[09:09:48] <ssi> what's the max bore on 16c?
[09:09:59] <JT-Shop> 1.625
[09:10:04] <ssi> gotcha
[09:10:11] <ssi> I think 5c is 1.0625
[09:10:51] <ssi> so i ordered a vfd, should be here tomorrow
[09:11:01] <ssi> my plan is to power up the machine with the original control via the vfd
[09:11:08] <ssi> jog it around and make sure everything works
[09:11:52] <JT-Shop> I tried powering mine up with a VFD but it started blowing things up in the main electrical cabinet so I stopped
[09:12:10] <JT-Shop> and connected it to my phase converter
[09:12:14] <ssi> did it?
[09:12:19] <ssi> shit that's what I was afraid of
[09:12:30] <ssi> I have a couple of 1hp statics
[09:12:47] <ssi> not nearly rated for it, but I won't be loading the spindle, so maybe it'll be ok?
[09:12:50] <ssi> heh
[09:13:34] <JT-Shop> dunno, heck I just wanted to power up the control and the light
[09:13:43] <ssi> yeah that's pretty much all I want to do
[09:13:46] <ssi> I want to run the servos a bit
[09:13:48] <ssi> make sure they work
[09:13:55] <ssi> run the coolant pump, cycle the collet closer
[09:13:59] <ssi> start and stop the spindle
[09:14:04] <ssi> if I can do those things, I'll be happy
[09:15:43] <mazafaka> ssi: my workshop:
http://www.youtube.com/watch?v=-wGKVrq7xq0
[09:16:07] <ssi> aw man, a video, why didn't I think of that?! :D
[09:21:14] <JT-Shop> video is nice but what is all that background noise?
[09:21:54] <Loetmichel> JT-Shop: its called "music" ... by some ppl ;-)
[09:22:04] <JT-Shop> not by me :P
[09:22:17] <Loetmichel> me neither
[09:22:42] * Loetmichel thought at forst of a vaccum running
[09:22:47] <Loetmichel> ;-)
[09:23:00] <Loetmichel> a shopvac with long tubes connected

[10:00:23] <ssi> mazafaka: where are you located?
[10:07:47] <mazafaka> Southe-west of Siberia in Russia, 'Kuzbass'
[10:12:17] <awallin> this looks interesting..
http://www.sciencedirect.com/science/article/pii/S0010448512000255?v=s5
[10:14:04] <Loetmichel> machine1: thats MUSIC
[10:14:08] <Loetmichel> (DM)
[10:14:44] <Loetmichel> machine1: just for info: i was a few 100 km nearar lately, went to Vilnius to make a presentation on monday ;-)
[10:15:00] <Loetmichel> (few 100 = 1700km ;-)
[10:15:45] <Loetmichel> <- still a bit bit worn down is, after driving 1750km nonstop in 16 hrs ;-)
[10:16:32] <Loetmichel> oh sorry, mazafaka was meant
[10:28:09] <FredrikHson> hi i was wondering if there is any setting or some such that lets the trajectory planner work better when you have hundreds/thousands of tiny short lines?
[10:29:29] <cradek> yes, G64 P[tolerance]
[10:35:59] <JT-Shop> FredrikHson:
http://linuxcnc.org/docview/2.5/html/common/User_Concepts.html
[10:36:35] <FredrikHson> ok that seems to work just have to add that to my post processor then
[10:37:18] <anonimas1> Tom_L: yes wrong ladder
[10:37:24] <anonimas1> err parameters for it
[10:37:52] <anonimas1> Tom_L: looks like im damn lucky as usual with tools :) it cuts surfaces that looks like ground
[10:38:12] <anonimas1> tho, im struggling to figure out how to set up tooling
[10:40:41] <FredrikHson> not 100% perfect but i got a nice 2x speedup from using a 0.05mm tolerance still 50% of the programmed speed but i don't think the machine itself can handle the accelerations fast enough anyway to run that shape
[10:43:31] <cradek> yes, the accel setting is the important one if you want to contour quickly, make sure it's as high as your machine can reasonably handle
[10:43:50] <anonimas1> im curious how much chips it will move at 9kw of power into a cut :p
[10:46:25] <FredrikHson> http://fredrikh.deviantart.com/gallery/8477118 if anyone feels even the slightest bit curious here is some of the stuff i have milled so far with my machine (took forever without that g64 thing ;)
[10:48:08] <djdelorie> reminds me of a time my mom asked me to print a photo of my dad with "as high a quality as you can". Took 45 minutes. Looked great, but would have been much faster and look the same with a not-quite-highest quality setting ;-)
[10:49:42] <cradek> FredrikHson: neat! some of those, like the skull, look like a workholding nightmare
[10:49:56] <djdelorie> anonimas1: with that much power, you could just carve the metal, rather than mill it :-)
[10:50:02] <anonimas1> lathe :)
[10:50:07] <anonimas1> 11kw spindle
[10:50:33] * djdelorie wants to see a 9kw Z axis for CNC broaching...
[10:50:38] <FredrikHson> milled the skull on a manual forth axis and just cut away from behind the jaw to let it loose when all the detailing everywhere else was done
[10:51:01] <JT-Shop> FredrikHson: nice work!
[10:54:13] <FredrikHson> http://www.youtube.com/watch?v=a04qV4MMEnw and my current setup
[10:55:01] <FredrikHson> but going to refit an emco pc mill 55 now and hopefully that runs even better
[10:55:18] <FredrikHson> haven't got the same highspeed spindle on that thing as my older machine tho :\
[10:58:33] <jdhnc> ls: what is the origin of this?
[11:00:09] <JT-Shop> FredrikHson: what are you using to generate your G code?
[11:01:54] <FredrikHson> mastercam
[11:02:28] <FredrikHson> only thing i found that could take triangle data when i first rebuilt that machine
[11:04:41] <JT-Shop> I use OneCNC but it needs a complete overhaul as it has major problems IMHO
[11:05:30] <JT-Shop> about the only thing predicable about is it a profile cut...
[11:07:13] <isssy> http://www.youtube.com/watch?v=CjVVNuraly8
[11:07:27] <tom3p> what is 'medium verteiler' ? looks like deep rib cutting at high rpm and no chips ( negligible chips )
[11:07:28] <tom3p> http://www.youtube.com/watch?feature=player_detailpage&v=yzoxOPfPCVU
[11:10:24] <tom3p> yes, like no chips, another vid shows a cut with & w/o the 'medium verteiler', you see chips, then you dont ( LOADS of chips then nada but stock keeps going away )
[11:12:19] <anonimas1> I use bobcad, it works.. not amazing but it makes parts and its fairly cheap
[11:12:39] <anonimas1> mostly 2.5d and limited 3d is what I do, the lathe stuff we'll see how it works.
[11:13:49] <joe9> is everyone using ubuntu for emc2? curious if anyone has it running fine with other distros or if they are noticing issues. (gentoo, debian, crux).
[11:14:01] <tom3p> mediumverteiler (de) -> medium distributer (eng) doesnt tell anything, except infers high pressure (air or liquid, dunno )
[11:14:08] <anonimas1> pretty much it's not worth the work to run something different
[11:16:55] <tom3p> mediumverteiler seems to be coaxial flushing ( like in wedm ) but at gun drill pressures ( a tube of flush around tool, working in deep slots )
[11:17:29] <tom3p> haha this is just like hole drill edm, same old stuff is now new
[11:18:01] <tom3p> "By the ring formation of the spray nozzle, there are also no shadows and blind spots during cooling, lubrication and blowing away the chips, resulting in an improvement of the workpiece surface, as well as a considerably longer service life of the cutter."
[11:18:50] <anonimas1> maybe worth making a ring and testing it out..
[11:19:42] <tom3p> get a dbl acting air amplifier and jack it up to 1500 - 2000 psi the orifice is teeny so the flow is low
[11:20:27] <tom3p> http://www.haskel.com/corp/details/0,,CLI1_DIV139_ETI9791,00.html
[11:23:03] <tom3p> needs hi speed spindle too, the vids used 80krpm afict
[11:26:06] <anonimas1> your just blowing away dust at thoose speeds.
[11:26:16] <tom3p> yah
[11:26:44] <anonimas1> nothing special, it's just like a cooler with minimum lube..
[11:26:47] <anonimas1> at high pressure
[11:27:04] <tom3p> did you see the size of the chip w/o the flush? not dust, big, sandy
[11:27:31] <anonimas1> yeah, but removing metal makes chips, they are there.. just blown away i guess..
[11:28:03] <tom3p> im not saying the chip size changes, but the blast sweeps up like crazy
[11:28:48] <anonimas1> I had a question for you about mitsubishi g90 edm for sale a few days ago
[11:28:50] <anonimas1> are they decent?
[11:28:54] <anonimas1> wedm..
[11:30:16] <tom3p> mits are good, lemme check model
[11:30:53] <tom3p> btw: that flushing bit is nice , see clearly at
http://www.merz-cnc-consult.de/index.php?page=mediumdistrib&view=gallery
[11:31:19] <tom3p> a hollow cone with tiny holes at anulus
[11:32:18] <tom3p> anonimas1, G90? sure?
[11:32:22] <anonimas1> 90g
[11:32:25] <anonimas1> sorry
[11:33:58] <tom3p> anonimas1, pretty old, no more than 500$ worth ( only if really clean ) get the DI tank & resin bottle and tooling too for the 500$
[11:34:17] <tom3p> wedms of that era (80's) are not valuable
[11:34:39] <tom3p> is stepper, is xyuv ( maybe z too )
[11:34:58] <anonimas1> I see, good that I cant conjure up cash for one in this second :)
[11:35:04] <anonimas1> about 3000eur
[11:35:32] <tom3p> best to see it cut 1" circle 1" thick & mike it up to see if round & straight & to size
[11:35:41] <anonimas1> I want to have a wedm, but not at that cost, and no awt.. that's a deal killer.
[11:37:06] <tom3p> people give away AGie 2 axis machines(70's), and 500$ is reasonable for 80's90's in working order.
[11:37:24] <anonimas1> not over here
[11:37:39] <anonimas1> cheapest i've found is a 7000eur sodick 80's machine
[11:37:49] <tom3p> old custom nc equip is impossible to get parts & fix
[11:46:22] <mazafaka> Loetmichel: Vilnus sounds as a former soviet territory
[11:57:39] <Loetmichel> mazafaka: lituania (spelling?)
[11:57:45] <ssi> http://fredrikh.deviantart.com/gallery/8477118#/d25s0fc
[11:57:46] <ssi> awesome
[11:57:47] <ssi> I want one :D
[11:58:25] <Loetmichel> and its Vilinus
[11:58:29] <Loetmichel> or wilna
[11:58:36] <Loetmichel> grrr
[11:58:39] <Loetmichel> Vilnius
[12:02:28] <Loetmichel> mazafaka: did this on saturday 12:00 to tuesday 11:00... ->

[12:04:20] <Loetmichel> the way TO vilnius was alone and with ferry, the way back was by car and with my boss driving half the time. STILL got no sleep ;-)
[12:05:53] <jdhnc> over 4 days? and a ferry ride? C'mon, that's nothing.
[12:06:06] <Loetmichel> ('caus boss has driven through poland with about 140km/hrs, even in the citys
[12:06:27] <Loetmichel> jdhnc: the ferry ride was more or less 24 hours sleep
[12:06:37] <Loetmichel> but the rest was enough
[12:06:47] <Loetmichel> started sat. 12:00
[12:07:01] <Loetmichel> got to kiel ferry sat 22:00
[12:07:21] <Loetmichel> got to klaipeda sun 22:30
[12:07:42] <IchGuckLive> hi all polarlights all over the planet sun is bombarding us !
[12:07:46] <Loetmichel> was in Vilnius by monday 03:50 in the morning -> hotel
[12:07:54] <Loetmichel> woke 07:30
[12:08:07] <Loetmichel> was at the military base 10:00
[12:08:48] <Loetmichel> -> half a ton computer in the third story, setup, presentation, repack it in the car
[12:09:02] <Loetmichel> 18:30-> back on the run to Offenbach
[12:09:18] <Loetmichel> arrived at tuesday 11:00
[12:10:00] <Loetmichel> STILL havent recovered a decent day/sleep rythm ;-)
[12:10:02] <alex4nder> Loetmichel: where're you located?
[12:10:15] <Loetmichel> Offenbach am main, germany
[12:10:45] <Loetmichel> why?
[12:10:58] <IchGuckLive> Loetmichel: look outside polar lights derektion NEDerlands
[12:11:16] <Loetmichel> IchGuckLive: not interested ;-)
[12:11:40] <ssi> dangit JT I'm really disappointed that I won't be able to run this control off the vfd :(
[12:12:10] <anonimas1> did it explode?
[12:12:15] <anonimas1> I exploded 2 of them.
[12:12:20] <anonimas1> err 3.
[12:12:21] <ssi> no, but I don't want it to explode!
[12:12:25] <ssi> what did you explode 3 of
[12:12:28] <anonimas1> vfd's
[12:12:30] <ssi> o
[12:12:31] <ssi> why?
[12:12:35] <ssi> or, how rather
[12:12:39] <anonimas1> my motor was wired up for some weird configuration
[12:13:15] <anonimas1> the third vfd was for 380 instead of 480 cheap ebay one -_-
[12:13:18] <Mjolinor> can you see the northern lights from there now?
[12:13:57] <anonimas1> it's way too cloudy right now
[12:14:00] <Mjolinor> I was hoping to get a look at them from ehre but as usual it's cloudy :(
[12:14:29] <Loetmichel> alex4nder: why?
[12:14:47] <alex4nder> Loetmichel: just wondering about that much travel around
[12:14:50] <alex4nder> wondering what the starting point was
[12:15:33] <mazafaka> Loetmichel: I am old for such rides. It's for you. visit the amsterdam, kid... Oh, oh, oh, I need to take my pills...
[12:15:39] <Loetmichel> alex4nder: thats the price of working in a company with international customers ;-)
[12:16:02] <mazafaka> Frankfurt on Main is a starting point
[12:16:12] <Loetmichel> mazafaka: i thought you are at most half my age...
[12:16:13] <Mjolinor> frankfurt airport is close enouigh for you to travel though
[12:16:16] <Loetmichel> <- 43
[12:16:20] <Mjolinor> I hate that airport
[12:16:39] <Loetmichel> Mjolinor: with half a ton military computer equipment?
[12:16:53] <Mjolinor> why not
[12:16:55] <mazafaka> Loetmichel: yes, but... 27 multiplied by five cats and two dogs = being near of the home
[12:17:57] <Loetmichel> mazafaka: at 27 i would have driven there in one run, made the presentation and driven back alone ;-)
[12:18:27] <Loetmichel> but at 43 the body tends to let me up sometimes :(
[12:18:43] <mazafaka> ha! but I would made this on a bicycle!
[12:19:37] * Loetmichel prefers the Mercedes E 230 tdi caravan from my company ;-)
[12:19:50] <mazafaka> in 43, you're waiting for a 45, when, as Russians say, 'the bitch is a berry again'
[12:19:52] <jdhnc> why didn't you take the company jet?
[12:20:06] <mazafaka> (they say it about the women)
[12:20:10] <Mjolinor> do they have jets yet in Germany?
[12:20:15] <ssi> I think my company needs a company jet
[12:20:31] <ssi> I found an L29 for sale for $30k recently
[12:20:54] <Loetmichel> the way back was a hell of a ride, boss tends to fly at FL 0 ;-)
[12:21:02] <mazafaka> heh, and in my turn, my company needs a topless hostess which stew potatoes with parsley and such!
[12:21:08] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12919
[12:21:39] <ssi> here's my current company jet:
[12:21:40] <ssi> http://www.airport-data.com/aircraft/photo/640592.html
[12:21:40] <Loetmichel> jdhnc: a company jet? in a company of 10 ppl?
[12:21:40] <ssi> :D
[12:21:55] <jdhnc> an analog clock? they still make those?
[12:21:56] <Loetmichel> the boss is WAY to cheap for that ;-)
[12:22:15] <Loetmichel> jdhnc: tha car is build in 2004 IIRC
[12:22:25] <Loetmichel> but as you can see: yes ;-)
[12:23:51] <IchGuckLive> Loetmichel: tdi TCDI ?
[12:24:41] <Loetmichel> IchGuckLive: no idea, this car:
http://www.cyrom.org/palbum/main.php?g2_itemId=12916
[12:24:47] <Loetmichel> (bottom left)
[12:24:55] <IchGuckLive> NO O.o
[12:25:26] <Loetmichel> sure a diesel, and from the sound of it a turbo
[12:25:45] <Loetmichel> but more: no idea. its a company car
[12:26:00] <Loetmichel> ... more like tha company "hooker" ;-)
[12:26:45] <IchGuckLive> as here the same E320 T CDI
[12:27:04] <IchGuckLive> with 3.8m long load capaziti
[12:27:46] <IchGuckLive> testet persenly 3.75m fits the hole garden house took in the car
[12:28:52] <Loetmichel> IchGuckLive: i drive a Opel Omega caravan as a private car...
[12:29:17] <Loetmichel> tell me about loar capacity ;-)
[12:29:19] <Loetmichel> load
[12:29:44] <Loetmichel> ( i think i can park the Eclass in the bunk of the Omega ;-)
[12:30:41] <IchGuckLive> O.o agree on that but not ride as far as the E
[12:32:07] <jdhnc> I could fit your Opel and tow the E
[12:32:15] <Loetmichel> oh, its a 2004 model with "execuitive" configuration
[12:32:30] <IchGuckLive> this week in germany there are somany routers Deckel FP3-4 in ebay i saw 4 today at endprice of 2.6k
[12:32:34] <Loetmichel> and with the 2.5liters 6cyl turbodiesel
[12:32:42] <Loetmichel> automatic
[12:32:54] <Loetmichel> so its quite comfortable ;-)
[12:33:41] <IchGuckLive> agree also
[12:35:06] <Loetmichel> but i wouldnt have driven the Omega 3000++km for the company 'cause boss simply wouldnt pay for the wear
[12:38:13] <IchGuckLive> by im off polarlights loking outside
[14:28:12] <Deuplonicus> quiet in here
[14:28:26] <alex4nder> all the euros are eating dinner
[14:29:22] <djdelorie> I could gripe about my current sensors if that would make you feel better... ;-)
[14:31:03] <Mjolinor> current as in "of the moment" or current as in V/R?
[14:32:17] <djdelorie> current as in "wrong resistor value"
[14:32:53] <djdelorie> I used 5 mR at first, but the signal was too weak, so I swapped for 50 mR, now that I have the driver working right, the signal is clipping, so back to 5 mR
[14:33:19] <djdelorie> given my recent enlightenment about what the current sensor is *for*, it's now important that I get it right...
[14:34:00] <Mjolinor> well it was probably also important befor ehte eureka moment oo, you jsut didn't knwo it :)
[14:34:28] <Mjolinor> and my typing still sucks
[14:35:58] <jepler> djdelorie, now there's a name that carries a lot of history.
[14:36:03] * jepler <-- djgpp user back in the 90s
[14:36:19] <jdhnc> damn, y'all are old.
[14:36:37] <jepler> in that narrow window between "ooh, I got a 386" and "this linux thing seems pretty neat"
[14:37:35] <jdhnc> I had a vax with a 20" graphics terminal.
[14:40:45] * djdelorie remembers building my first 386 motherboard...
[14:41:53] <djdelorie> jdhnc: a microvax workstation?
[14:43:56] <djdelorie> Mjolinor: yes, it was important before, and I put the sensors in because I knew there was a reason for them, but now (1) I know why, and (2) turns out I actually need to use them to get the thing to stop at the right spot.
[14:45:37] <djdelorie> I mean, I'm aiming for 0.09 degree precision on a 1/3 HP motor, so IT MATTERS.
[14:46:15] <alex4nder> djdelorie: what kind of mill/lathe/whatever are you converting?
[14:46:34] <jdhnc> dj: uVaxII-GPX
[14:47:10] <djdelorie> jdhnc: I worked on a uVAX at Yale one summer, doing machine vision and simulating one of the first real-time cat scanners for the lab next door. Fun box.
[14:48:07] <jdhnc> I used it to do code for a real time ultrasonic inspection system.
[14:48:11] <djdelorie> alex4nder: a simple 2ftx2ft CNC machine. We started with the motors, which we got from surplus. No specs, nothing online, just motors with wires...
[14:48:21] <Deuplonicus> I'm curious, is there a way to move an image around in axis, so that it cuts within your cutting zone?
[14:48:26] <alex4nder> djdelorie: gotcha
[14:48:46] <djdelorie> machine:
http://www.delorie.com/photos/cnc/ controller:
http://www.delorie.com/electronics/bldc/
[14:49:15] <djdelorie> it's partly a desire to have a CNC machine, and partly a desire to expand my "envelope" with a new project.
[14:50:03] <Deuplonicus> nice machine
[14:50:19] <Deuplonicus> also, is there an easy way to rescale some gcode to make it larger?
[14:54:36] <jepler> if you're *writing* the gcode, it's possible to build in a general scaling factor using gcode math -- look at the way the axis splash screen does this
[14:55:13] <jepler> if you're getting the gcode from somewhere, there's not a scale factor available (except either *25.4 or /25.4 by programming the wrong unit code)
[14:56:59] <Mjolinor> you could redefine your step size in the hal file :)
[14:57:07] <Mjolinor> suppose that's cheating really :)
[14:57:26] <alex4nder> haha
[14:57:33] <Deuplonicus> haha, thats easy
[14:59:31] <jepler> exercise: write a Python program that will read a linuxcnc inifile, modify the scales according to a given scale factor, and also correctly modify the velocity and acceleration limits
[14:59:41] <jepler> (don't forget the square in acceleration)
[15:00:00] <djdelorie> jepler: for the same effort, you could write a program that scales the gcode instead...
[15:00:08] <Mjolinor> or jsut sit here watching crap on TV instead
[15:00:29] <jepler> parsing an inifile is an order of magnitude more tractible than parsing gcode
[15:02:21] <archivist> someone is going to cringe when he looks hard at gcode :)
[15:02:22] <mrsun> building in wood ... cheap but in a year, what size will your machine be? :P
[15:03:21] <alex4nder> mrsun: maybe he'll make a new machine with his first mill
[15:03:30] <mrsun> alex4nder, true =)
[15:03:36] <mrsun> thats the spirit =)
[15:03:45] <alex4nder> I kind of want to do that with my taig.
[15:04:00] <alex4nder> but I also think I should just buy a VMC from the 80s or early 90s with broken controls.
[15:04:03] <mrsun> alex4nder, and me with my X1 =)
[15:04:17] <mrsun> but i cant seem to finnish the X1 to any state where i can start making parts :P
[15:04:21] <mrsun> its cursed or something
[15:04:30] <alex4nder> what's wrong with it?
[15:04:34] <mrsun> always some kind of rebuild going on :P
[15:04:42] <alex4nder> of what?
[15:04:46] <mrsun> had ti working fine, but then .. "well lets scrape the ways" ... so i did
[15:04:51] <alex4nder> oh
[15:04:53] <mrsun> took about 4 months to get it together again
[15:04:54] <alex4nder> yah
[15:05:02] <mrsun> now im working on the control system for the spindle etc
[15:05:10] <alex4nder> I'm such a noob, I knew if I bought a machine that needed that, I'd never have gotten CNC working.
[15:05:12] <mrsun> or its some motor mount rebuild
[15:05:18] <mrsun> always something :P
[15:05:52] <mrsun> alex4nder, i didnt think the machine was that bad in shape, but the scraping has done so huge differences in performance of the machine it feels untrue
[15:06:11] <mrsun> before the table etc when tightened to not bind anywhere could rock about 0.1mm at the end ...
[15:06:15] <mrsun> now its solid
[15:06:24] <alex4nder> ah
[15:06:28] <mrsun> or 0.1 .. it was even worse
[15:06:33] <alex4nder> that's pretty serious
[15:06:40] <mrsun> when the table was sticking out fully it rocked like 1mm in the very end
[15:07:00] <mrsun> and added oil groves to it also =)
[15:07:09] <mrsun> so its prepeared for central oiling :P
[15:07:19] <mrsun> best X1 out there soon i think :P
[15:07:23] <alex4nder> haha
[15:07:27] <alex4nder> how many hours of labor?
[15:07:55] <mrsun> alex4nder, scraping i dont know, took an hour here and one there, and im a total noob so ... maybe 4 - 5 workdays or something
[15:08:01] <mrsun> for scraping the ways and table
[15:08:08] <alex4nder> oh I meant total on the machine
[15:08:12] <mrsun> lol
[15:08:24] <mrsun> ive had the machine for like 7 years, doing some here and some there
[15:08:32] <alex4nder> ah ok.
[15:08:54] <mrsun> i get bored when stuff doesnt go my way and i dont do stuff on it for a couple of weeks or months
[15:09:02] <mrsun> then i get the spirit up again etc :P
[15:09:16] <mrsun> now im all flames cause i got the vfd to start/stop and set spindle speed from emc =)
[15:09:29] <djdelorie> alex4nder: that's the idea, use this to build new machines... Mostly, we designed the machine around the spare parts we had, just to get something working and learn the process. It's my first CNC.
[15:09:36] <mrsun> but need to rebuild the spindle 0 - 10V board
[15:09:42] <djdelorie> plus, my woodworking skills far exceed my machining skills :-)
[15:10:02] <mrsun> hehe =)
[15:10:12] <mrsun> wood is easy to work with =)
[15:10:18] <mrsun> so you get results fast
[15:10:23] <mrsun> and ALOT cheaper then metal :P
[15:10:46] <Deuplonicus> what free cad shit do you guys use? I was using solidworks til it expired
[15:10:46] <mrsun> so doesnt hurt as bad when you drill that stupid hole in the wrong location =)
[15:11:22] <mrsun> Deuplonicus, ive been using freecad latley for cadding or qcad, and used heekscad for the cam work
[15:12:54] <Deuplonicus> is the cam software for making the gcode? I have only experience with 3d modeling and I've never made my own gcode file from a drawing yet
[15:13:11] <Mjolinor> I have problems with heekscad crashing
[15:13:44] <alex4nder> Deuplonicus: welcome to the pain of CNC
[15:14:32] <mrsun> yeah heeks is a pita
[15:14:35] <Mjolinor> I used to use solidworks and have been going through them lately and I htink so far freecad for the cad adn heekscad for the CAM seems the easiest option
[15:15:02] <alex4nder> I've been writing my own 2.5D routines, and doing it by hand.
[15:15:14] <alex4nder> watching most CAM software's output makes me want to bash my head into the wall.
[15:15:14] <mrsun> Deuplonicus, heeks is a 3d modeller with cam functionality by an addon (heekscnc) its very dodgy and crashes often so keep stuff saved, and its heekscnc that generates the gcode for you yes =)
[15:15:16] <Mjolinor> I got really pissed off at freecad because hte tutorials didnt work until I discovered that the version in the ubuntu feeds was different, once I installed from the home page it is fine to follow the tutorials
[15:15:28] <mrsun> freecad is alot more stable and nicer to work with in the 3d modeling apartment then heeks
[15:16:03] <mrsun> Mjolinor, ubuntu is problematic that way, some software is old as sin :/
[15:16:25] <Mjolinor> well I am on 11.04, I will not go to unity, its crap
[15:16:36] <Mjolinor> so problay all the sw on this machine is old
[15:17:00] <mrsun> yeah unity sucked
[15:17:09] <Mjolinor> I installed heeks on this yesterday, it took 7 hours to install, I stuck it on a bodhi linux machien today adn it installed straight fmor the debs in about 5 minutes
[15:17:13] <mrsun> you know you can still use gnome classic right? :P
[15:17:30] <Deuplonicus> thanks guys
[15:17:31] <Mjolinor> i am doing
[15:17:37] <Mjolinor> but you cant if you go to 11.10
[15:18:06] <Mjolinor> I am done wiht ubuntu now, once this machine needs a reinstall I iwll go with either bodhi or mint
[15:18:32] <mrsun> Mjolinor, im using 11.10
[15:18:36] <Mjolinor> linux used to be so good because everyone involved with it followed the principle that if it aint broke don't fix it
[15:18:40] <mrsun> and using gnome fine
[15:18:53] <mrsun> its just a bit garbled up in the menues :P
[15:18:55] <Mjolinor> but last few ubuntu updats ahve achieved nohtign interms of useability and just suck resources
[15:19:17] <Mjolinor> its following the windows path I think
[15:19:26] <mrsun> gnome3 wasnt fun either
[15:19:34] <Mjolinor> change the colour and make it fancier and people will use it
[15:19:35] <mrsun> have to use classic mode for it to be usable
[15:19:53] <mrsun> Mjolinor, im just waiting for Haiku to become more usable for me
[15:20:11] <Mjolinor> not looked at it
[15:20:19] <mrsun> Mjolinor, simplicity in its finest form =)
[15:20:44] <Mjolinor> IO will try that i htink
[15:20:53] <mrsun> only reason i do not have it on this computer is due to the fact that my wlan isnt supported yet :/
[15:21:03] <mrsun> and it lacks alot of software
[15:21:15] <Mjolinor> its a shame really, ubuntu jsut got nice a easy to use even for non linux users, you could actually install it for normal people
[15:21:20] <mrsun> (rembmer haiku is NOT linux)
[15:21:32] <Mjolinor> normal peopl :) , I mean people that had no interest in computers but wanted to use them
[15:22:03] <mrsun> a friend of mine wanted ubuntu installed cause he had seen the version with unity ...
[15:22:10] <mrsun> i wanted to break his nose
[15:22:12] <mrsun> =)
[15:22:19] <Mjolinor> obviously a windows user :)
[15:22:25] <mrsun> Mjolinor, mac
[15:22:36] <Mjolinor> :)
[15:25:33] <mrsun> ahh finaly pressed the order button on the electronic stuffs i need
[15:25:39] <mrsun> now its for the long wait to get it :P
[15:26:06] <Mjolinor> you need a loft like mine
[15:26:09] <Mjolinor> it has it all in :)
[15:27:09] <mrsun> slowly building up my stack of stuff in all ways i can without alot of money comming in =)
[15:28:04] <mrsun> hopefully i might get a work opertunity at a saw mill im working for "free" at now (for my education as an electrician) but i shouldnt get my hopes up =)
[15:28:26] <Mjolinor> where are you?
[15:28:40] <mrsun> huh ? :)
[15:28:46] <Mjolinor> must be the states :) that is the only place where they have sawmills
[15:29:00] <mrsun> Mjolinor, or whatever its called, its in sweden
[15:29:05] <Mjolinor> :)
[15:29:32] <Mjolinor> I remmeber now
[15:29:39] <Mjolinor> getting old sucks, memory goes to shit
[15:31:01] <mrsun> http://www.fiskarheden.se/wk_custom/images/%7Bd80165a6-2185-4625-afc4-cc9ee0688f75%7D_001.jpg <-- there =)
[15:31:27] <mrsun> is where im working now, a stop just costs about 6000sek/minute ... so not very fun trying to fix errors etc for the operators :P
[15:59:49] <ssi> DANIMAL
[16:37:29] <DJ9DJ> gn8
[16:49:32] <Deuplonicus> hey guys, I just made my first gcode with cambam, and it doesn't want to run, not to mention it is also a .nc file
[16:54:30] <JT-Shop> why doesn't it "want" to run?
[16:54:58] <alex4nder> it's protesting.
[16:59:09] <Deuplonicus> haha, i figured it out
[16:59:19] <Deuplonicus> some spindle on and tool change commands that I don't have anyhow
[16:59:36] <Deuplonicus> we got it working but we realized the Z-axis scale is WAY off
[16:59:42] <Deuplonicus> is there a mathematical way to do this?
[17:00:38] <Deuplonicus> cause I flunked algebra
[17:00:47] <Deuplonicus> lol, not really.... eigenvevtors ftw!
[17:01:30] <ssi> I wish someone would write a worthwhile osx cam app
[17:01:39] <ssi> does cambam do lathe work worth a crap?
[17:08:05] <JT-Shop> Deuplonicus: it only takes basic math to figure your scale
[17:08:16] <JT-Shop> or I'd be screwed for sure
[17:14:26] <JT-Shop> ssi: I just use ngcgui on the CHNC for 99% of the ops
[20:50:48] <seb_kuzminsky> i'm enjoying this guy's "Knifemaking Tuesday" video:
https://www.youtube.com/user/JohnGrimsmo
[21:36:08] <elmo40> interesting
[22:15:12] <joe9> the rtai stuff uses a 2.6.11 kernel. is it possible to use a later 3.x kernel with rtai?
[22:15:32] <joe9> i am kinda nervous about all the things that will break by going back to that kernel.
[22:15:52] <joe9> i am trying to use the instructions at
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?RtaiSteps
[22:16:21] <alex4nder> joe9: you should install the LinuxCNC ubuntu install to start out with
[22:16:59] <joe9> alex4nder: oh, ok. I have a debian machine already and was trying to see if I could get it to work with linuxcnc.
[22:17:15] <joe9> if ubuntu is the only option, then have to figure out how to upgrade to ubuntu.
[22:17:36] <joe9> wondering if it is kinda simple to get linuxcnc to work with debian.
[22:18:57] <alex4nder> it's easy to get the simulation environment working
[22:24:26] <joe9> alex4nder: any suggestions on how I can migrate from debian to ubuntu without burning a cd?
[22:25:25] <alex4nder> I'd ask a question first: which computer are you planning to run the mill with?
[22:30:19] <joe9> lshw of the machine:
http://codepad.org/JED08Oj0
[22:30:25] <joe9> alex4nder: good enough?
[22:32:14] <alex4nder> joe9: you should burn the live CD, so that you can run a latency test.
[22:32:26] <joe9> alex4nder: oh, ok.
[23:39:52] <danimal_laptop|3> anyone know how to keep my plasma and welder from dicking with my computer? everytime i use them in the general area my usb devices stop working until i unplug them and plug them back in again.
[23:49:57] <|n0b0dy|> danimal_laptop|3 shielding?
[23:50:32] <danimal_laptop|3> encase my computer in lead?
[23:50:42] <|n0b0dy|> trying putting a cookie tin around the usb device..
[23:51:42] <|n0b0dy|> they make a nice faraday cage... the metal kind w/ lid, that some people collect religiously...
[23:53:14] <|n0b0dy|> :D
[23:53:33] <|n0b0dy|> thats my first thought.. do you get any error message?
[23:54:28] <|n0b0dy|> or is the pwoer draing causing the usb devices to shtudown?
