[00:27:56] <tehDarkAura> running nema 23 and nema 17 off the same PSU is okay right?? I mean thats what the 1/4 1/2 current levels are for... right?
[00:28:55] -!- sumpfralle [sumpfralle!~lars@cpc23-seve18-2-0-cust109.13-3.cable.virginmedia.com] has joined #linuxcnc
[00:29:08] <tehDarkAura> planning on have the psu put out 24 V but just read not to use more then 12 on nema 17
[00:29:50] <tehDarkAura> im pretty sure it wont matter as long as i cut the current back some
[00:36:46] <A2Sheds> I was thinking about the methods discussed earlier for measuring plastic filament thickness
[00:37:24] <A2Sheds> if the extrusion speed is faster than 30fps for the field of view
[00:37:31] <A2Sheds> using a camera
[00:38:52] <djdelorie> how completely and precisely do you need to check the length of the filament?
[00:40:21] <A2Sheds> within 1% for 1.5mm and 3mm dia
[00:40:38] <A2Sheds> not length measurement, diameter
[00:42:03] <A2Sheds> inexpensive laser interferometry
[00:42:09] <joe9> alex4nder: which is preferred for engraving bits (taig), with or without the ring?
[00:45:21] <djdelorie> I mean, are you spot checking along the length, or do you really need to measure every spot along its length?
[00:46:36] <A2Sheds> every spot, dia changes really effect 3dp
[00:47:26] <tehDarkAura> well whats the plan if its larger then expected?
[00:47:36] <tehDarkAura> slow a feed or pressure or something?
[00:47:49] -!- skunkworks__ has quit [Ping timeout: 248 seconds]
[00:48:15] <A2Sheds> yes
[00:48:46] <A2Sheds> the PLA is extruded through a sapphire orifice
[00:49:16] <A2Sheds> so the dia almost always is under sized vs over when extruding
[00:49:54] <tehDarkAura> hmm interesting
[00:49:57] <A2Sheds> if the take up reel moves too fast or there is too much tension on the filament
[00:50:13] <A2Sheds> over size would be weird
[00:50:40] <A2Sheds> bubbles from gas or moisture still in the extruded plastic
[00:51:52] <tehDarkAura> so your planning on using a cam with macro focus and a custom linux motion mask ?
[00:52:32] <A2Sheds> typical extruders are worm type
[00:53:07] <A2Sheds> the plastic exits the nozzles and enter a cooling tank, then dryer, then take up reel
[00:53:34] <A2Sheds> the take up reel is like a tape recorder or web printing press
[00:53:46] <tehDarkAura> ahhhh
[00:53:52] <A2Sheds> tension of the filament is easily measured and controlled
[00:54:24] <A2Sheds> over tension and the filament will shrink
[00:55:24] -!- bedah has quit [Quit: Ex-Chat]
[01:00:42] <tehDarkAura> could always have more then one cam to increase feild of view
[01:01:09] <tehDarkAura> but coding a response working with multiple cams would be tricky

[01:05:44] <A2Sheds> CCD line scanner
[01:05:57] <A2Sheds> or webcam array
[01:06:29] <A2Sheds> still lower cost than a laser micrometer
[01:18:55] <djdelorie> run the filament through a chamber; pump air into the chamber at a known rate, measure the pressure. The air escapes through the gap in the holes by the filament proportional to the filament size?
[01:19:04] <A2Sheds> 1024 x 1 CCD array, 37khz line rate = 111mm/sec for 3um pixels
[01:19:55] <A2Sheds> >4 inches /second, fast enough

[01:21:25] <A2Sheds> with 30um pixels, 1.1m/sec extrusion speed
[01:21:56] <djdelorie> or just two photodiodes, one on each side, measure analog voltage as the filament partially obscures each...
[01:24:13] <A2Sheds> what about glow in the dark filament? :)
[01:24:33] <A2Sheds> or clear, just kidding
[01:25:31] <Tom_itx> anonimas1 did you figure out your issue with singlestep?

[02:00:09] <tehDarkAura> i remeber a avr tech note on the effect of different plastic front panels on the capacitive touch sensors but i cant find it now
[02:02:05] <tehDarkAura> you could have something grounded on the other side of your filament and measure if the capacitance changes and change your feed rate accoringly
[02:03:30] <tehDarkAura> would want to use a self capacitive button style i would think
[02:03:47] <tehDarkAura> http://www.atmel.com/Images/doc10752.pdf
[02:04:23] <tehDarkAura> thats for the button design -- there is also a table outlines a bunch of different materials and how their thickness effects the buttons but cant find

[04:08:30] <ssi> yaaaa
[04:08:35] <ssi> I'm really glad I decided to get it
[04:08:40] <ssi> it was an enormous pain in the ass

[13:42:34] <ssi> my goal is to lay out a new panel and cnc plasma cut it
[13:42:49] <ssi> and replace the U-stor memory unit with a keyboard tray
[13:43:05] <jdhnc> need an avr or something to run the nixies via serial
[13:43:24] <ssi> yea I haven't decided if I want to try to use the nixies as a DRO on the machine

[13:44:15] <jdhnc> DRO, as GE intended.
[13:44:23] <ssi> it actually wasn't a DRO on this machine
[13:44:34] <ssi> left side is tool offset display, right side is MDI interface
[13:44:59] <jdhnc> that wouldn't be very interesting
[13:45:45] <ssi> I agree!
[13:46:05] <jdhnc> 14 char scrolling #LinuxCNC display
[13:48:01] <ssi> the possibilities are endless :D
[13:48:15] <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
[13:48:24] <ssi> I'm hoping I can fit everything I want hardware wise into that one black panel
[13:48:28] <ssi> since it's its own little door
[13:49:12] <ssi> I wish I could find someone with a tape punch

[14:15:46] <jdhnc> ouch... but the uncovered thing was only a part of the problem.
[14:20:26] <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>

[14:44:55] <theos> expansion*
[14:44:59] <JT-Shop> what is that?
[14:45:14] <theos> yes HP's proprietary port for docking stations/port replicators
[14:45:30] <JT-Shop> ah laptop
[14:45:41] <theos> the docking station that is attached to the port provides a parallel port

[14:51:53] <mazafaka> theos: you think the laptop itself will be allright during its work with RTAI ? What if it heats up too much?
[14:52:29] <theos> mazafaka why will it heat up too much? :)
[14:52:31] <ssi> JT-Shop: you familiar with the little setup arbor tools that go with the hardinge lathes?

[14:53:00] <ssi> like that one, and there's another one that measures off the bed and has a little swinging cap
[14:53:27] <mazafaka> theos: because ACPI functions are turned off
[14:53:33] <JT-Shop> never seen one before is that for setting tool height?
[14:53:37] <ssi> yea I think so
[14:53:43] <ssi> I'm trying to get an idea of how exactly they're used
[14:53:44] <JT-Shop> I use a level thingy
[14:53:45] <ssi> I have the other one
[14:53:49] <ssi> wondering if I should get this one too
[14:54:00] <JT-Shop> let me see if I can find a link to it

[14:54:30] <mazafaka> ssi: For WFL, we have a tool measuring thingie with monitor and something
[14:54:37] <theos> mazafaka i also have an old desktop. intel 440bx. will that work? P3 450mhz. 64mb ram :D
[14:54:41] <JT-Shop> owo on sale too
[14:54:50] <ssi> yea that's probably more useful at the end of the day :)
[14:55:17] <ssi> also, I need to get some step chuck collets
[14:55:28] <ssi> the guy I bought the lathe from had a pile of them, but he sorta talked me out of buying them
[14:55:29] <mazafaka> theos: anyway, try to be sure laptop will work OK
[14:55:41] <ssi> now I have a small production contract that has just come up for making 2" x 2-3/8" parts
[14:55:42] <theos> mazafaka thanks
[14:55:46] <ssi> and a 2" step chuck would be really nice
[14:56:01] <JT-Shop> step chuck?
[14:56:17] <theos> mazafaka btw what would you recommend?
[14:56:19] <ssi> http://www.amazon.com/5CC-3-5C-Chuck-Clutch-Collet/dp/B0007Q3G6W
[14:56:35] <ssi> they have a closer ring that seats on the spindle nose
[14:56:40] <ssi> the taper on yours, the threads on mine
[14:56:43] <JT-Shop> ah ok, yea I have a few of them
[14:57:07] <JT-Shop> the ones with the taper ring on the spindle nose are stronger
[14:57:18] <ssi> maybe so
[14:57:23] <ssi> but mine's threaded, so I get what I get
[14:58:09] <JT-Shop> the spindle is threaded?
[14:58:13] <ssi> yeah
[14:58:42] <ssi> yours has that 4 degree taper on the outside of the nose
[14:58:45] <ssi> mine is straight with a thread
[14:58:46] <JT-Shop> mine is a 16c collet and I can mount a normal chuck on it as well
[14:58:55] <ssi> and mine's 5c rather than 16c
[14:59:46] <ssi> http://www.shophardinge.com/product.aspx?partNo=14230000000000
[14:59:49] <JT-Shop> I make some 2 1/4" parts on mine from time to time
[15:00:17] <ssi> what's the max bore on 16c?
[15:00:29] <JT-Shop> 1.625
[15:00:34] <ssi> gotcha
[15:00:40] <ssi> I think 5c is 1.0625
[15:01:20] <ssi> so i ordered a vfd, should be here tomorrow
[15:01:30] <ssi> my plan is to power up the machine with the original control via the vfd
[15:01:38] <ssi> jog it around and make sure everything works
[15:02:22] <JT-Shop> I tried powering mine up with a VFD but it started blowing things up in the main electrical cabinet so I stopped

[16:27:53] <anonimas1> err parameters for it
[16:28:22] <anonimas1> Tom_L: looks like im damn lucky as usual with tools :) it cuts surfaces that looks like ground
[16:28:41] <anonimas1> tho, im struggling to figure out how to set up tooling
[16:31:11] <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
[16:34:01] <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
[16:34:19] <anonimas1> im curious how much chips it will move at 9kw of power into a cut :p
[16:36:55] <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 ;)

[16:40:12] <cradek> FredrikHson: neat! some of those, like the skull, look like a workholding nightmare

[17:00:53] <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 )
[17:02:48] <anonimas1> I use bobcad, it works.. not amazing but it makes parts and its fairly cheap
[17:03:08] <anonimas1> mostly 2.5d and limited 3d is what I do, the lathe stuff we'll see how it works.
[17:04:18] <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).
[17:04:31] <tom3p> mediumverteiler (de) -> medium distributer (eng) doesnt tell anything, except infers high pressure (air or liquid, dunno )
[17:04:37] <anonimas1> pretty much it's not worth the work to run something different
[17:07:24] <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 )
[17:07:58] <tom3p> haha this is just like hole drill edm, same old stuff is now new
[17:08:31] <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."
[17:09:19] <anonimas1> maybe worth making a ring and testing it out..
[17:10:11] <tom3p> get a dbl acting air amplifier and jack it up to 1500 - 2000 psi the orifice is teeny so the flow is low

[17:25:33] <anonimas1> about 3000eur

[17:54:49] <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 ;-)
[17:56:22] <jdhnc> over 4 days? and a ferry ride? C'mon, that's nothing.
[17:56:36] <Loetmichel> ('caus boss has driven through poland with about 140km/hrs, even in the citys
[17:56:56] <Loetmichel> jdhnc: the ferry ride was more or less 24 hours sleep
[17:57:06] <Loetmichel> but the rest was enough
[17:57:17] <Loetmichel> started sat. 12:00
[17:57:30] <Loetmichel> got to kiel ferry sat 22:00

[17:58:16] <Loetmichel> was in Vilnius by monday 03:50 in the morning -> hotel
[17:58:23] <Loetmichel> woke 07:30
[17:58:36] <Loetmichel> was at the military base 10:00
[17:59:17] <Loetmichel> -> half a ton computer in the third story, setup, presentation, repack it in the car
[17:59:31] <Loetmichel> 18:30-> back on the run to Offenbach
[17:59:47] <Loetmichel> arrived at tuesday 11:00
[18:00:30] <Loetmichel> STILL havent recovered a decent day/sleep rythm ;-)
[18:00:32] <alex4nder> Loetmichel: where're you located?
[18:00:44] <Loetmichel> Offenbach am main, germany
[18:01:14] <Loetmichel> why?
[18:01:28] <IchGuckLive> Loetmichel: look outside polar lights derektion NEDerlands
[18:01:45] <Loetmichel> IchGuckLive: not interested ;-)
[18:02:09] <ssi> dangit JT I'm really disappointed that I won't be able to run this control off the vfd :(
[18:02:39] <anonimas1> did it explode?
[18:02:44] <anonimas1> I exploded 2 of them.
[18:02:50] <anonimas1> err 3.
[18:02:50] <ssi> no, but I don't want it to explode!
[18:02:54] <ssi> what did you explode 3 of

[18:02:59] <ssi> o
[18:03:00] <ssi> why?
[18:03:04] <ssi> or, how rather
[18:03:08] <anonimas1> my motor was wired up for some weird configuration
[18:03:44] <anonimas1> the third vfd was for 380 instead of 480 cheap ebay one -_-
[18:03:48] <Mjolinor> can you see the northern lights from there now?
[18:04:27] <anonimas1> it's way too cloudy right now
[18:04:30] <Mjolinor> I was hoping to get a look at them from ehre but as usual it's cloudy :(
[18:04:58] <Loetmichel> alex4nder: why?
[18:05:16] <alex4nder> Loetmichel: just wondering about that much travel around
[18:05:20] <alex4nder> wondering what the starting point was
[18:06:02] <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...
[18:06:08] <Loetmichel> alex4nder: thats the price of working in a company with international customers ;-)
[18:06:32] <mazafaka> Frankfurt on Main is a starting point
[18:06:42] <Loetmichel> mazafaka: i thought you are at most half my age...
[18:06:43] <Mjolinor> frankfurt airport is close enouigh for you to travel though
[18:06:45] <Loetmichel> <- 43
[18:06:50] <Mjolinor> I hate that airport
[18:07:08] <Loetmichel> Mjolinor: with half a ton military computer equipment?

[18:10:21] <jdhnc> why didn't you take the company jet?
[18:10:35] <mazafaka> (they say it about the women)
[18:10:40] <Mjolinor> do they have jets yet in Germany?
[18:10:44] <ssi> I think my company needs a company jet
[18:11:00] <ssi> I found an L29 for sale for $30k recently
[18:11:23] <Loetmichel> the way back was a hell of a ride, boss tends to fly at FL 0 ;-)

[18:15:55] <Loetmichel> sure a diesel, and from the sound of it a turbo
[18:16:15] <Loetmichel> but more: no idea. its a company car
[18:16:29] <Loetmichel> ... more like tha company "hooker" ;-)
[18:17:15] <IchGuckLive> as here the same E320 T CDI
[18:17:34] <IchGuckLive> with 3.8m long load capaziti

[18:20:13] <Loetmichel> ( i think i can park the Eclass in the bunk of the Omega ;-)
[18:21:10] <IchGuckLive> O.o agree on that but not ride as far as the E
[18:22:36] <jdhnc> I could fit your Opel and tow the E
[18:22:44] <Loetmichel> oh, its a 2004 model with "execuitive" configuration
[18:22:59] <IchGuckLive> this week in germany there are somany routers Deckel FP3-4 in ebay i saw 4 today at endprice of 2.6k

[20:18:41] <Deuplonicus> quiet in here
[20:18:55] <alex4nder> all the euros are eating dinner
[20:19:52] <djdelorie> I could gripe about my current sensors if that would make you feel better... ;-)
[20:21:33] <Mjolinor> current as in "of the moment" or current as in V/R?
[20:22:47] <djdelorie> current as in "wrong resistor value"
[20:23:23] <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
[20:23:48] <djdelorie> given my recent enlightenment about what the current sensor is *for*, it's now important that I get it right...
[20:24:29] <Mjolinor> well it was probably also important befor ehte eureka moment oo, you jsut didn't knwo it :)
[20:24:57] <Mjolinor> and my typing still sucks
[20:26:27] <jepler> djdelorie, now there's a name that carries a lot of history.
[20:26:33] * jepler <-- djgpp user back in the 90s
[20:26:49] <jdhnc> damn, y'all are old.
[20:27:07] <jepler> in that narrow window between "ooh, I got a 386" and "this linux thing seems pretty neat"
[20:28:05] <jdhnc> I had a vax with a 20" graphics terminal.
[20:31:15] * djdelorie remembers building my first 386 motherboard...
[20:32:23] <djdelorie> jdhnc: a microvax workstation?
[20:34:25] <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.
[20:36:06] <djdelorie> I mean, I'm aiming for 0.09 degree precision on a 1/3 HP motor, so IT MATTERS.
[20:36:45] <alex4nder> djdelorie: what kind of mill/lathe/whatever are you converting?
[20:37:04] <jdhnc> dj: uVaxII-GPX
[20:37:40] <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.
[20:38:36] <jdhnc> I used it to do code for a real time ultrasonic inspection system.
[20:38:40] <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...
[20:38:51] <Deuplonicus> I'm curious, is there a way to move an image around in axis, so that it cuts within your cutting zone?
[20:38:56] <alex4nder> djdelorie: gotcha
[20:39:16] <djdelorie> machine: http://www.delorie.com/photos/cnc/ controller: http://www.delorie.com/electronics/bldc/
[20:39:45] <djdelorie> it's partly a desire to have a CNC machine, and partly a desire to expand my "envelope" with a new project.
[20:40:32] <Deuplonicus> nice machine
[20:40:49] <Deuplonicus> also, is there an easy way to rescale some gcode to make it larger?
[20:45:06] <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
[20:45:43] <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)
[20:45:53] -!- jbunch has quit [Ping timeout: 245 seconds]
[20:47:28] <Mjolinor> you could redefine your step size in the hal file :)
[20:47:36] <Mjolinor> suppose that's cheating really :)
[20:47:56] <alex4nder> haha
[20:48:02] <Deuplonicus> haha, thats easy
[20:50:01] <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
[20:50:10] <jepler> (don't forget the square in acceleration)
[20:50:30] <djdelorie> jepler: for the same effort, you could write a program that scales the gcode instead...
[20:50:37] <Mjolinor> or jsut sit here watching crap on TV instead
[20:50:59] <jepler> parsing an inifile is an order of magnitude more tractible than parsing gcode
[20:52:50] <archivist> someone is going to cringe when he looks hard at gcode :)
[20:52:52] <mrsun> building in wood ... cheap but in a year, what size will your machine be? :P
[20:53:50] <alex4nder> mrsun: maybe he'll make a new machine with his first mill
[20:54:00] <mrsun> alex4nder, true =)
[20:54:05] <mrsun> thats the spirit =)
[20:54:14] <alex4nder> I kind of want to do that with my taig.
[20:54:29] <alex4nder> but I also think I should just buy a VMC from the 80s or early 90s with broken controls.
[20:54:32] <mrsun> alex4nder, and me with my X1 =)
[20:54:47] <mrsun> but i cant seem to finnish the X1 to any state where i can start making parts :P
[20:54:50] <mrsun> its cursed or something
[20:54:59] <alex4nder> what's wrong with it?
[20:55:04] <mrsun> always some kind of rebuild going on :P
[20:55:11] <alex4nder> of what?
[20:55:16] <mrsun> had ti working fine, but then .. "well lets scrape the ways" ... so i did
[20:55:21] <alex4nder> oh
[20:55:22] <mrsun> took about 4 months to get it together again
[20:55:23] <alex4nder> yah
[20:55:32] <mrsun> now im working on the control system for the spindle etc
[20:55:39] <alex4nder> I'm such a noob, I knew if I bought a machine that needed that, I'd never have gotten CNC working.
[20:55:42] <mrsun> or its some motor mount rebuild
[20:55:48] <mrsun> always something :P
[20:56:21] <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
[20:56:40] <mrsun> before the table etc when tightened to not bind anywhere could rock about 0.1mm at the end ...
[20:56:44] <mrsun> now its solid
[20:56:53] <alex4nder> ah
[20:56:57] <mrsun> or 0.1 .. it was even worse
[20:57:02] <alex4nder> that's pretty serious
[20:57:10] <mrsun> when the table was sticking out fully it rocked like 1mm in the very end
[20:57:30] <mrsun> and added oil groves to it also =)
[20:57:38] <mrsun> so its prepeared for central oiling :P
[20:57:49] <mrsun> best X1 out there soon i think :P
[20:57:53] <alex4nder> haha
[20:57:56] <alex4nder> how many hours of labor?
[20:58:25] <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
[20:58:31] <mrsun> for scraping the ways and table
[20:58:38] <alex4nder> oh I meant total on the machine
[20:58:42] <mrsun> lol
[20:58:53] <mrsun> ive had the machine for like 7 years, doing some here and some there
[20:59:01] <alex4nder> ah ok.
[20:59:13] e-ndy is now known as e-ndy|afk
[20:59:24] <mrsun> i get bored when stuff doesnt go my way and i dont do stuff on it for a couple of weeks or months
[20:59:32] <mrsun> then i get the spirit up again etc :P
[20:59:46] <mrsun> now im all flames cause i got the vfd to start/stop and set spindle speed from emc =)
[20:59:59] <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.
[21:00:05] <mrsun> but need to rebuild the spindle 0 - 10V board
[21:00:12] <djdelorie> plus, my woodworking skills far exceed my machining skills :-)
[21:00:31] <mrsun> hehe =)
[21:00:41] <mrsun> wood is easy to work with =)
[21:00:48] <mrsun> so you get results fast
[21:00:52] <mrsun> and ALOT cheaper then metal :P
[21:01:15] <Deuplonicus> what free cad shit do you guys use? I was using solidworks til it expired
[21:01:15] <mrsun> so doesnt hurt as bad when you drill that stupid hole in the wrong location =)
[21:01:52] <mrsun> Deuplonicus, ive been using freecad latley for cadding or qcad, and used heekscad for the cam work
[21:03:23] <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
[21:03:41] <Mjolinor> I have problems with heekscad crashing
[21:04:13] <alex4nder> Deuplonicus: welcome to the pain of CNC
[21:05:01] <mrsun> yeah heeks is a pita
[21:05:04] <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
[21:05:31] <alex4nder> I've been writing my own 2.5D routines, and doing it by hand.
[21:05:43] <alex4nder> watching most CAM software's output makes me want to bash my head into the wall.
[21:05:44] <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 =)
[21:05:46] <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
[21:05:57] <mrsun> freecad is alot more stable and nicer to work with in the 3d modeling apartment then heeks
[21:06:33] <mrsun> Mjolinor, ubuntu is problematic that way, some software is old as sin :/
[21:06:54] <Mjolinor> well I am on 11.04, I will not go to unity, its crap
[21:07:06] <Mjolinor> so problay all the sw on this machine is old
[21:07:29] <mrsun> yeah unity sucked
[21:07:39] <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
[21:07:42] <mrsun> you know you can still use gnome classic right? :P

[21:09:02] <mrsun> Mjolinor, im using 11.10
[21:09:05] <Mjolinor> linux used to be so good because everyone involved with it followed the principle that if it aint broke don't fix it

[21:09:22] <mrsun> its just a bit garbled up in the menues :P

[21:11:22] <mrsun> only reason i do not have it on this computer is due to the fact that my wlan isnt supported yet :/
[21:11:33] <mrsun> and it lacks alot of software
[21:11:44] <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
[21:11:49] <mrsun> (rembmer haiku is NOT linux)
[21:12:02] <Mjolinor> normal peopl :) , I mean people that had no interest in computers but wanted to use them
[21:12:32] <mrsun> a friend of mine wanted ubuntu installed cause he had seen the version with unity ...
[21:12:40] <mrsun> i wanted to break his nose
[21:12:42] <mrsun> =)
[21:12:49] <Mjolinor> obviously a windows user :)

[22:40:01] <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
[22:45:00] <JT-Shop> why doesn't it "want" to run?
[22:45:27] <alex4nder> it's protesting.
[22:49:38] <Deuplonicus> haha, i figured it out
[22:49:48] <Deuplonicus> some spindle on and tool change commands that I don't have anyhow
[22:50:05] <Deuplonicus> we got it working but we realized the Z-axis scale is WAY off
[22:50:12] <Deuplonicus> is there a mathematical way to do this?
[22:51:08] <Deuplonicus> cause I flunked algebra
[22:51:16] <Deuplonicus> lol, not really.... eigenvevtors ftw!
[22:51:59] <ssi> I wish someone would write a worthwhile osx cam app
[22:52:08] <ssi> does cambam do lathe work worth a crap?

[23:04:56] <JT-Shop> ssi: I just use ngcgui on the CHNC for 99% of the ops
