[00:01:15] <JT-Shop> yes, too many times :)
[00:01:44] <JT-Shop> it's like concrete I don't let anyone local know I'm skilled in those trades
[00:02:56] <cpresser> just a question to improve my language skills: what is 'to sheetrock'?
[00:03:01] <Gensor> good for you. I can do it... but it is tedious work for me. I rented a lift do do my brothers 11ft ceiling in his garage and attempted to have mating tapered joints
[00:03:48] -!- theorb [theorb!~theorb@] has joined #emc
[00:03:48] -!- theorbtwo has quit [Read error: Operation timed out]
[00:04:03] theorb is now known as theorbtwo
[00:04:08] <Gensor> dry wall, sheetrock, is a fire resistant material in a sheet that you nail/screw in to 2x4 studs
[00:07:29] <cpresser> ty. i also googled a few pictures.. the german name is 'gipskarton'
[00:07:35] <Gensor> the same place I rented the lift I asked who was a good contractor for cheap.... got an excellent contractor to tape and texture for $550. it now looks like a huge master bedroom
[00:09:02] <JT-Shop> cpresser: also known as gypsum
[00:09:59] <JT-Shop> I figured out long ago that the less mud you use the better it is :) less sanding
[00:10:32] <JT-Shop> a lift is a must for old farts like me
[00:10:47] <cpresser> sanding this stuff makes so much dust.. i hate it
[00:10:50] <Valen> called gyprock in australia
[00:11:07] <Valen> cpresser: power sander with vacuum attachment? ;->
[00:11:18] <Gensor> ack!
[00:11:42] <Gensor> too much mud if you have to do that
[00:12:05] <Valen> I was thinking to keep the dust down more than going fast
[00:12:25] <Valen> JT-Shop: run more than you think you'll need and don't forget speakers ;->
[00:12:57] <Gensor> I always like to leave a fish string for future expansion
[00:15:28] <JT-Shop> Valen: I forgot speakers! gotta have jams
[00:15:47] <Valen> zacterly ;->
[00:15:52] <Valen> going to run alarm stuff?
[00:15:56] <JT-Shop> everything that is covered up is in conduit so I can pull it out and swap/add if needed
[00:16:08] <JT-Shop> not needed out here
[00:16:54] <Valen> not even if it includes a tazer? ;->
[00:17:20] <JT-Shop> tazer is not much of a match to a 12 gauge up close
[00:18:06] <JT-Shop> I''m in a very rural area :)
[00:18:15] <Valen> it is if its wired in to your windows like an electric fence and the "baddie" isn't expecting it
[00:18:21] <Valen> saves you money on a siren too
[00:18:36] <JT-Shop> is that better than claymores?
[00:18:41] <Valen> less messy
[00:18:43] <JT-Shop> LOL
[00:18:51] <JT-Shop> ah , yea you have a point
[00:21:28] <JT-Shop> I do have motion activated lights around all the buildings
[00:21:44] <JT-Shop> keeps me from falling down more than anything LOL
[00:22:46] <Valen> i'm planning on putting one of those in my hallway
[00:24:33] <Jymmm> JT-Shop: and stubing over gators
[00:24:37] <Jymmm> JT-Shop: and stubling over gators
[00:25:40] <Gensor> does anyone have that link to the robot arm that is carving a huge bear?
[00:26:34] <Valen> http://coderedsurvivalkits.com/escapeparachute.asp
[00:26:49] <Valen> lol was looking for something for my missus
[00:27:09] <Valen> she is working in a building with a tax office and a welfare office as ground floor tennants
[00:27:21] <Valen> that was not exactly what I had in mind
[00:27:29] <Valen> but still, ya gotta laugh a little
[00:28:52] * JT-Shop wanders inside to strap on the feed bag
[00:28:55] <JT-Shop> goodnight

[00:35:43] <Jymmm> Valen: You gotta love it.... One or even 5 donuts, yet 20 ppl on a floor. What happene to the 6th bastard? http://www.donutsafeland.com/Pages/advantages.html
[00:36:03] <Valen> they should be reusable
[00:36:11] <Valen> just pull the thing back up
[00:36:28] <Jymmm> and the device through 100ft ot cord too?
[00:36:33] <Jymmm> and the device through 100ft of cord too?
[00:36:59] <Valen> lets just say i figure you would have suitable motivation ;-P
[00:37:23] <Jymmm> Is that before or after the fire has reached you?
[00:38:00] <Jymmm> and wtf is the nylon strap all about... you know that's going to twist and bind in the device
[00:39:21] <Jymmm> nylon strap for a make shift harness, sure.
[00:40:18] <Jymmm> I do have 100ft of antenna guy rope though for such a thing. Rated at 700lbs
[00:41:48] <Valen> Jymmm: its designed for office ladies to be able to use
[00:42:17] <Jymmm> Maybe, but the desending device is shit imo
[00:42:30] <Jymmm> to reuse that is in a timely maner
[00:42:55] <Valen> you would probably find that they are meant to be one to a person or something
[00:43:08] <Valen> they use them on oil rigs so they wont suck too badly
[00:43:21] <Jymmm> Use, but not REuse
[00:43:27] <Valen> why reuse it
[00:43:31] <Valen> everybody has their own
[00:43:36] <Jymmm> Yu hope
[00:43:46] <Jymmm> $1000/each
[00:43:49] <Valen> on an oil rig thats probably the case
[00:44:03] <Valen> heh on a rig that would be nothing
[00:44:04] <Jymmm> on a rig, there's not 100 ppl
[00:44:38] <Valen> http://coderedsurvivalkits.com/personaldescentdevice.asp
[00:44:42] <Valen> has some backround on it
[00:44:50] <Jymmm> and I love how they do NOT prodive detaild pics or manual
[00:44:59] <Jymmm> yes, theres where I saw it at
[00:45:22] <Valen> if your that worried get one of these http://coderedsurvivalkits.com/escapeparachute.asp
[00:45:44] <Tom_itx> that was my thought. what if the rope is too short?
[00:45:45] <Tom_itx> :D
[00:45:46] <Jymmm> fuck that thing. I gots me 1000ft of rope =)
[00:45:56] <Valen> you carry that with you all the time ;-P
[00:46:01] <Jymmm> Tom_itx: 100ft == 10 story apx
[00:46:16] <Jymmm> Valen: You would be surprised what I carry with me =)
[00:46:17] <Tom_itx> not much good in NYC
[00:46:26] <Tom_itx> probably not
[00:46:28] <Jymmm> FSCK NYC
[00:47:00] <Valen> hah, should make the missus a 100ft "screamer"
[00:47:15] <Valen> leap out window, have an arrested fall the whole way down
[00:47:26] <Jymmm> Except for the SPOT, most of the stuff on there is crap
[00:49:17] <Valen> hmm might need a steel carabiner but http://www.spearitco.com/index.php?main_page=product_info&products_id=221 could work
[00:49:33] <Valen> space is at an absolute premium for the kit i want for the missus
[00:50:03] <Valen> with some kevlar anti knife gloves she should be able to use it
[00:50:16] <Valen> and the gloves would be useful in any case
[00:50:52] <Valen> Jymmm: that webbing they use in that other descender would be ok for hand over hand i reckons ;-> you work out right?
[00:51:48] <Jymmm> Valen: It might be, but looks really thin.
[00:52:01] <Valen> didn't look that thin to me
[00:52:37] <Jymmm> it's like 1/16" thick
[00:52:52] <Jymmm> not anything you would use climbing
[00:53:05] <Tom_itx> 400lb test isn't that much
[00:53:19] <Valen> Tom_itx: mm, probably right
[00:53:24] <Valen> 3mm isn't that much bigger
[00:53:25] <Tom_itx> for putting your whole body weight on
[00:53:26] <Jymmm> Tom_itx: especially on shock test
[00:53:39] <Valen> its 900lb
[00:53:44] <Tom_itx> they make cord almost as thin with like 3000lb test
[00:53:44] <Tom_itx> or more
[00:53:52] <Valen> Tom_itx: orly?
[00:53:59] <Tom_itx> pretty sure
[00:54:03] <Valen> that was just the first that I found
[00:54:10] <Tom_itx> i have some climbing rope but it's 5/8"
[00:54:29] <Jymmm> My rope is 3/8 and rated at 700lbs
[00:54:34] <Valen> yeah thats too big
[00:54:36] <Tom_itx> the other is used mostly for acessory
[00:54:53] <Tom_itx> iirc this is rated at 5-6k
[00:55:00] <Jymmm> Valen: Dude, you can't have THAt small a kit.
[00:55:06] <Jymmm> Valen: be realistic
[00:55:25] <Valen> if its much bigger than a pencil case she wont take it ergo its useless
[00:55:47] <Valen> so do the best with what we can
[00:55:58] <Tom_itx> this was about 1/2 pencil size
[00:56:16] <Jymmm> Then knife, fire, light

[00:58:42] <Valen> I know all this
[00:58:59] <Valen> its a secondary system
[00:59:20] <Tom_itx> http://www.rocknrescue.com/acatalog/PMI%20Tech.pdf
[00:59:22] <Valen> its just got to give better odds than staying in the building
[00:59:52] <Jymmm> how many stories?
[01:00:07] <Valen> 6 or so i think
[01:00:19] <Tom_itx> you can drop 3 and do just fine
[01:00:30] <Valen> you can drop 3 and be dead too
[01:00:33] <Tom_itx> maybe broken limbs but survivable
[01:00:52] <Valen> Tom_itx: thats what I'm hoping to mitigate somewhat
[01:01:21] <Tom_itx> that 7.5mm looks ok
[01:01:28] <Valen> too big physically
[01:01:37] <Tom_itx> fire and rescue rope
[01:02:11] <Valen> i mean don't get me wrong, that is the *right* stuff to use
[01:02:31] <Valen> but as with most engineering there is a compromise, if its too big it wont fit and hence won't get used
[01:02:48] <Tom_itx> you want a little give to it but not very much
[01:02:49] -!- Birdman3131 has quit [Ping timeout: 252 seconds]
[01:02:51] <Jymmm> or she just leaves it at the office
[01:02:56] <Tom_itx> or static rope and a slip harness
[01:02:58] <Valen> I'm looking for the "minimum" that "should do the job on a good day if the wind is in the right direction"
[01:04:00] <Valen> I was thinking one could make a wrist strap webbing with steel descender as the "sling"
[01:04:12] <Jymmm> worse case scenario
[01:04:30] <Valen> sure the decender will be pretty roasty by the time you get to the bottom but eh, only has to work once
[01:05:35] <Valen> and on a kevlar line the heat wont bother it
[01:05:57] <Valen> Jymmm: can't leave it there, she works at a bank, somebody will flog it
[01:08:21] <Valen> hmm, if i can somehow make the bag out of the rope that would be nifty
[01:09:03] <Valen> make the bag out of kevlar tape, held together with cotton stiching
[01:09:13] <Valen> put on floor and rip it apart to get the rope

[01:17:23] <Tom_itx> http://www.atwoodrope.net/product-list.php?pg1-cid42.html
[01:22:04] <Valen> thats pretty teensy rope
[01:22:18] <Valen> actually I want some like that for some torches i'm making
[01:23:15] <Tom_itx> i haven't found a spec page
[01:23:35] <Valen> 80lb i think it said

[01:24:04] <Tom_itx> i didn't look far either :)
[01:24:07] <Valen> lol
[01:24:50] <Tom_itx> i have some fishing string that's probably that strong
[01:25:08] <Valen> most of its strenght is probably lost in the weaving

[02:08:20] <Valen> and the rope came about from a parachute
[02:09:38] <Tom_itx> i swear i should keep 2 drives for every system i have

[04:59:00] <Connor> Valen: Depth of cut....
[04:59:35] <Valen> there is a thingie i saw somewhere to probe the PCB and get a height map
[04:59:36] <Connor> V bits are very picky on depth.. the deeper you go, the wider the cut.. and thus, my traces end up being too small, (mostly the pads) or get oblirated..
[04:59:58] <Valen> and then modufy the gcode or some such coming in to make the PCB come out right
[05:01:07] <Valen> was working with EMC as i recall
[05:01:38] <Connor> Does it take into account height changes along the X/Y plane?
[05:02:00] <Connor> Example, on the Y, looks like the machine started cutting more shallow.
[05:02:22] <Valen> yeah it probes a grid as i recall
[05:02:53] <Valen> specifically for wobbly pcbs
[05:03:51] <Connor> Fracked up by 45degree V bit.. told machine to go to .25 but, it was in MM not inches.. crashed the bit into the PCB..
[05:03:59] <Valen> oops
[05:04:33] <Valen> drove a diamond tool into glass at 10 meters a minute rather than 10 mm a minute a few weeks ago
[05:04:38] <Valen> oops
[05:04:43] <Connor> then.. with my 90's I had a brain fart and offset Z be .25" instead of .125" and on the first cut (which was a large circle) the bit wne all the way through the PCB and into the MDF PCB holder.
[05:05:09] <Connor> I think the bit is okay...
[05:05:32] <Connor> doesn't look damaged.. it did the reset of the job ok except for the issue with the depth being off.
[05:06:56] <Valen> they can be fussy
[05:08:34] <Connor> I want a PTFE ring on adjustable standoff that goes on the bottom of the router.. then I want to put springs under the PCB mount.. and use the ring + standoff's to adjust the depth of cut.
[05:09:15] <Connor> I'm not sure if that would affect the X/Y accuracy or not though..
[05:22:12] <JustinXJS3> I make a lot of PCBs and have found polycarbonate to be a better spoil board than MDF
[05:25:16] <Connor> My main spoil board is MDF, I then pocketed out a 1/2" small sized one that the PCB's fit in.. thinking that would be good enough..
[05:25:18] <Connor> guess not.

[17:51:57] <jdhNC> yeah, it's about time Al fixed it
[17:52:06] <IchGuckLive> JT do you now AC servo Drivers
[17:52:29] <JT-Shop> I use Panasonic
[17:52:57] <IchGuckLive> its more a question on my XtraDrive
[17:53:26] <IchGuckLive> can i make this moving to Step and Dir signal ?
[17:53:34] <anonimasu> IchGuckLive: why would you ever want to?
[17:54:13] <anonimasu> IchGuckLive: if you can forget step and direction.
[17:54:57] <IchGuckLive> is this better to drive to RXD and TXD ?
[17:55:04] <anonimasu> no, 0-10v is better
[17:55:30] <anonimasu> that's for serial, and as far as i know emc does not support that
[17:55:44] <IchGuckLive> i se but how can i make the pricise moovment
[17:56:41] <anonimasu> well, if step and dir is your only option that will give you precise movement at the cost of speed unless you have a pulse generator like the mesa hardware
[17:57:07] * JT-Shop still waits for the real question :)
[17:57:27] <IchGuckLive> anonimasu: http://tinyurl.com/3tn94qk here is a pdf documentation of the driver
[17:57:42] <anonimasu> do you have a english one?
[17:57:58] <IchGuckLive> no sorry
[17:58:03] <anonimasu> then i cant help you
[17:58:28] <anonimasu> it says Spannungsabweichung Nennspannung ±10%: 0% (bei Nenndrehzahl)
[17:58:33] <anonimasu> err wrong line
[17:59:03] <anonimasu> you have a speed input
[17:59:10] <anonimasu> Drehzahl-
[17:59:10] <anonimasu> Sollwert-
[17:59:11] <anonimasu> Eingang
[17:59:12] <IchGuckLive> anonimasu: can you google Xtradrive XD-01-MN01-E maybee you will providet by omron with a english one
[17:59:36] <anonimasu> and you also have a Drehmoment-
[17:59:36] <anonimasu> Sollwert-
[17:59:37] <anonimasu> Eingang
[17:59:50] <anonimasu> so you can run it in velocity or torque mode
[18:00:13] <anonimasu> and you have a impulse input
[18:00:15] <anonimasu> it seems like
[18:00:18] <IchGuckLive> ok si need another part that makes the coordinates to the Driver into Volts
[18:00:51] <IchGuckLive> Mesacard ?
[18:00:51] <anonimasu> you have 3 options
[18:00:59] <anonimasu> one is slow, and shitty step + direction
[18:01:07] <IchGuckLive> i want fix max tourqe
[18:01:26] <anonimasu> another one is velocity mode,
[18:01:29] <IchGuckLive> and max 2501/min
[18:01:34] <anonimasu> and another one is torque mode
[18:01:40] <IchGuckLive> 250 rpm
[18:02:11] <anonimasu> which one you want depends a bit on your machine and how you want to control it
[18:02:31] <anonimasu> torque/velocity would both work but require you to get a 0-10v card from something like mesanet.com
[18:02:38] <anonimasu> (if this is for emc)
[18:03:19] <IchGuckLive> its for the C-axis and it is controld by only a AVR the AVR gets a signal and the C-axis shoudt move only programmt forward
[18:03:32] <anonimasu> or you can hook it up to your paralell port and use step and direction but it's usually not satisfactory at all and you dont get the big benefit of a servo
[18:03:58] <IchGuckLive> ok i see
[18:04:20] <anonimasu> the point with the mesa boards if to get position feedback into emc
[18:04:28] <IchGuckLive> can i use 5V or do i have to use 24V fore the signals
[18:04:44] <anonimasu> Line-Treiber (+5-V-Pegel), offener Kollektor (+5-V- oder +12-V-Pegel)
[18:04:46] <archivist> read the docs for levels
[18:05:03] <anonimasu> you know this is very very basic stuff that's very well covered online
[18:05:04] <IchGuckLive> ok
[18:05:40] <archivist> we expect you to do some reading of your docs for your equipment
[18:05:40] <anonimasu> velocity mode probably would be a really good option along with a mesa board
[18:06:04] <anonimasu> how do you run the other parts of your machine?
[18:06:08] <archivist> dunno why avr was mentioned at all
[18:06:54] <anonimasu> IchGuckLive: also, with that you have a real servo axis(with closed loop feedback)
[18:07:41] <IchGuckLive> agree this is all a big miss at the moment
[18:08:00] <IchGuckLive> the Big mashines are Haas VF2
[18:08:34] <Connor> I implemented a touch-off thing last night on my machine.. It works.. however.. I have a issue with it.. I can't get it to go down far enough.. It's using ladder logic.. which I have no idea how to use.
[18:08:34] <anonimasu> how do you plan on getting a signal out of them for the last axis?
[18:09:29] <IchGuckLive> anonimasu: its just the #1133=1 tat gifes me the signal to turn the C-axis
[18:09:59] <anonimasu> IchGuckLive: I see, hence the avr right?
[18:10:11] <IchGuckLive> yes
[18:10:24] <Connor> it's all based on this thread.. http://www.cnczone.com/forums/emc_linux_enhanced_machine_control/62423-touch-off_plate_cnc_router.html
[18:10:32] <anonimasu> do you have that part done? with the avr?
[18:10:50] <IchGuckLive> and this is giving the stepper the signals for now but stepper is 1Nm and Servo is 25Nm

[19:13:21] <archivist> layout
[19:13:53] <Connor> Anyone have a good source for HDPE ? I want to remake my router mount out of it... Currently router mount is made from two .75" MDF glued together..
[19:14:45] <archivist> go for a better material than plastic
[19:15:04] <Connor> Umm.. like what?
[19:15:10] <jdhNC> unless you need to cut it with an MDF router
[19:15:24] <Connor> Bingo.
[19:15:51] <archivist> rigidity matters
[19:16:14] <Connor> The hole machine is made from MDF..
[19:16:38] <Connor> It's design for wood/plastic and thin sheet alum... nothing more.
[19:16:43] <jdhNC> 2x .75 mdf might be more rigid than a lot of plastic
[19:17:18] <Connor> Maybe, except I've torn through 2 already with the clamping nut/bolt setup.
[19:17:36] <archivist> plywood or one of the really dense woods
[19:17:53] <Connor> dense woods won't work.. It'll crack along the grain.
[19:18:49] <archivist> there are some dense manufactured random direction materials
[19:19:22] <Connor> has to be engineered wood, or plywood.. but, plywood isn't a good choice either, because it too can break through if you try to run a bolt horizontally through it.
[19:19:53] <archivist> then ally time
[19:20:07] <Connor> huh ?
[19:20:49] <archivist> aluminium or better
[19:21:19] <Connor> Oh. yea.. Well.. that's nice... I'll have to wait till I get my mill, or have someone else make it.

[19:24:00] <Connor> The one I have now is fine.. I'm just a little causes about it.. and I need to remake it again because the new design will use rare earth magnets for the dust shoe.. and I need smaller holes..
[19:24:33] <Connor> I figured if I was going to go through the trouble of making it again, might as well make it out of solid HDPE and be done with it.

[19:43:59] <Jymmm> the answer is no
[19:44:13] -!- Vladimirek has quit [Remote host closed the connection]
[19:44:30] <ewidance> :) I got a spindle controlled by pwm. Works fine on EMC2 and i can control speed. But...
[19:45:26] <ewidance> The spindle takes time to get it's final speed. When i start a program, it starts immediatly.... before spindle could get its nominal speed.
[19:45:56] <ewidance> Is the a way to setup a delay before a M3 Sxxx, execution and next line...
[19:45:58] <ewidance> ??

[19:46:49] <micges> ewidance: there is pin motion.spindle-at-speed
[19:47:27] <ewidance> i'm searching in the manual...
[19:47:34] <micges> http://www.linuxcnc.org/docview/html/config_emc2hal.html#r1_1
[19:49:18] <skunkworks> without feedback it will have to be a timing thing. I could see a delay between the spindle on and the motion at speed signal in hal. You could get as fancy as scaling the delay by the s word so lower spinlde speeds delayed less time than higher ones.
[19:49:29] <skunkworks> I think
[19:49:30] -!- Athlocatle has quit [Quit: υΘΟΦΥ]
[19:51:13] <ewidance> I found that: http://linuxcnc.org/docs/html/examples_spindle.html#r1_5
[19:51:55] <skunkworks> that is an even better solution.
[19:52:22] <ewidance> I try to understand...
[19:52:34] <JT-Shop> :)
[19:55:36] <ewidance> In that case, it's a fixed timeout provided by spindle-ramp.maxv 60
[19:55:44] <ewidance> is it?
[19:57:37] <skunkworks> http://linuxcnc.org/docs/html/man/man9/limit2.9.html
[19:58:15] <skunkworks> it is a to limit the slew rate of maxv(60) per second
[20:01:05] <skunkworks> so - I think in this example - it would in effect limit the spindle to accellerate 60rpm per second every second.
[20:01:53] <skunkworks> so after the first second - the rpm is 60 - after the second - the rpm is 120 and so on.
[20:02:25] <skunkworks> I feel as if I am making sense
[20:04:52] <ewidance> Hmm. I'm going to test...
[20:05:51] <skunkworks> bbl
[20:11:52] <mrsunshine> anyone have experience with bearings like these: http://www.dynametal.co.th/dry_dx.htm and cnc? :)
[20:12:36] <ewidance> Error : scale.0.in does not exist??? What's scale in http://linuxcnc.org/docs/html/examples_spindle.html#r1_5
[20:15:07] <ewidance> Does not seem to be declared...
[20:17:43] <awallin> scale is a component that multiplies a float signal. that example assumes there is a "loadrt scale" somewhere else (another hal file)
[20:18:58] <JT-Shop> In the 0-10 volt example the line "net spindle-speed-scale motion.spindle-speed-out => scale.0.in" is changed as shown in the following example.
[20:19:17] <skunkworks> ewidance: instead of hooking it to the 'scale' pin - hook it to whatever you are generating the pwm with
[20:20:15] <JT-Shop> the soft start example is an enhancement of the 0-10 example
[20:21:07] <ewidance> ok thanks. I look forward.
[20:22:57] <ewidance> I have to mix pwm example & 0-10V + hack. Anyone got a shaker :)

[20:57:21] <ewidance> Can i disconnect a pin/net in custom.hal, already connected in my_machine.hal? (ie:
[21:00:00] <cradek> unlinkp
[21:00:07] <ewidance> thnks..
[21:00:13] <ewidance> thanks..
[21:00:36] <cradek> the halcmd man page has basic hal usage
[21:01:20] <Connor> So, who Maintains EMC source code ?
[21:01:53] <cradek> many people have a part in the community
[21:01:57] <mrsunshine> hmm i guess on a lathe the friction of the bed is a "good" thing for it not to move with backlash etc
[21:02:21] <Connor> I was wondering who started it.. and if they're still involved with it's development.
[21:02:50] <cradek> it started in the US government (NIST) and none of those original people are still involved, as far as I know.
[21:05:04] <Paragon39> cradek: Am I correct in understanding that MACH3 uses the part of the original EMC code?
[21:05:36] <cradek> yes, it uses parts taken from the old EMC (pre-EMC2).
[21:05:59] <Connor> Your kidding me.. It's a fork?
[21:06:35] <Paragon39> Yep EMC1... How are they able to charge for it if they use the EMC1 open source code?
[21:06:41] <cradek> I don't know how much of the original EMC was used in Mach - at least the full gcode interpreter was. it's fairly hard to know for sure because Mach is closed.
[21:06:56] <cradek> the original EMC was public domain so it was perfectly fine for Mach to use parts of it.
[21:07:10] <Paragon39> Oh I see...
[21:07:22] <cradek> that is no longer possible with EMC2 because it is available only under the GPL2.
[21:07:49] <Connor> I still have issues with running a machine like a CNC with Windows as the controller..
[21:08:09] <Connor> Something about is just... wrong.
[21:08:24] <Paragon39> I am not that familiar with all the different licencing available within the open source community.
[21:09:00] <Connor> GNU, GPL 2 and 3, Apache, BSD...
[21:09:44] <Connor> http://en.wikipedia.org/wiki/Comparison_of_free_software_licenses
[21:10:07] <Paragon39> Apache and BSD is not a licence but rather products right? Ie Webserver and Unix type OS?
[21:10:17] <ewidance> I wish to thank everybody who helps me to find a solution for managing spinup time of my spindle... With few adaptations that works perfectly... The power of hal is really amazing!
[21:10:38] <ewidance> Anybody interrested with the source code?
[21:10:40] <Connor> Yes they're software.. but they made their own license.. look at the wiki link I just posed.
[21:11:15] <Paragon39> Connor: I will do... I wasn't aware apache had it's own licence.
[21:11:38] <Connor> Although, it's not showing the differences between the versions.. GPL2 vs GPL3 is prett big.
[21:12:42] <Paragon39> ewidance: it is very powerful isn't it. I am just about to get into the ladder stuff as I need to setup up my denford tool changer within EMC control. It uses grey code.
[21:14:41] <ewidance> IYes it is. I just played few with ladder, just to modify the joystick example to adapt to my needs. I use it to move the machine since i don't have a real pendant. I put my money on mill, not on pendant ;)

[21:16:02] <MOGLI> anyone knows about NESTING software in linux???
[21:16:21] <MOGLI> like BOBCAD for windows... sheetcam also supports nesting i think
[21:16:47] <Jymmm> MOGLI: IF you find any for nix, let me know
[21:17:01] <MOGLI> sure Jymmm
[21:18:04] <Connor> I use CamBAM.. it does.. but it's windows
[21:18:53] <Paragon39> Does UG-NX offer nesting?
[21:19:12] <MOGLI> Connnor: is it opensource??
[21:19:48] <Paragon39> UG-NX certainly isn't opensource ;-)
[21:20:05] <MOGLI> CamBAM. nt UG-NX
[21:21:22] <Paragon39> I no I was being mucking about ;-)
[21:22:47] <Paragon39> MOGLI: CamBam have a download link... look like it maybe opensource ... http://www.cambam.info/downloads/

[21:24:04] <Paragon39> Ooopps, Maybe not I've just seen there shop http://www.cambam.co.uk/shop/
[21:25:31] <Paragon39> MOGLI: CamBam will provide 40 free and fully functional evaluation sessions. After this time CamBam will still produce around 500 lines of gcode so you can continue to evaluate and run small jobs.
[21:26:05] <ewidance> Cambam is not open source but it's cheap and really powerful. Unfortunately, it does not work on linux. I tried Wine and Crossover...
[21:27:13] <Paragon39> It may run under Sun Virtualbox...
[21:27:45] <MOGLI> hmmmm.... is there any known plug-in for Inkscape etc?
[21:27:52] <MOGLI> i tried google but failed
[21:28:24] <Paragon39> MOGLI: I'm not familiar with Inkscape.
[21:28:33] <MOGLI> its really strange because nesting is common functionality for sheetmetal profiles wood etc
[21:28:44] <ewidance> Ther's a demo version with 40 launch. yes it may, or in Xen, or Vmware... But it's a bit heavy for one software...
[21:28:46] <MOGLI> even i am not thats why asking ... ha ha ha.

[21:36:36] <Paragon39> For example, given the files red_ball.svg and blue_triangle.svg:
[21:36:37] <Paragon39> svg_stack.py --direction=h --margin=100 red_ball.svg blue_triangle.svg > shapes.svg
[21:36:39] <Paragon39> will stack them horizontally with a 100 px margin between them. The result will be in a file called shapes.svg.

[23:51:29] <landau> noone?
[23:52:11] <landau> i need help! how to set correct jog speed value on emc2?
[23:52:36] <atom1> that and patience
[23:52:39] <andypugh> What do you want to change?
[23:53:09] <andypugh> Do you want more or less jog speed?
[23:53:25] <landau> i want more jog speed
[23:53:50] <andypugh> Is the current speed less than the G0 speed?
[23:53:56] <landau> i set it to 51 mm/min
[23:54:47] <landau> after 50 the slide jump to 70 mm/min and the stepper don't spin well!
[23:55:08] <landau> mmm...i don't know! what is G0 speed?
[23:55:12] <andypugh> You can change it by editing the INI file
[23:55:13] <andypugh> http://www.linuxcnc.org/docview/html/config_ini_config.html#sub:%5BDISPLAY%5D-section
[23:56:05] <landau> ohhhg good!
[23:56:27] <andypugh> G0 speed is how fast the machine moves when you issue a G0 command.
[23:56:55] <andypugh> (In G-code, or in the MDI tab (where you can type G-code line-by-line)
[23:57:07] <landau> understood...but what is G0 command?
[23:57:14] <andypugh> Rapid move
[23:57:32] <landau> really?..interesting
[23:57:34] <andypugh> Compared to G1 which is move at feed speed.
[23:57:45] <landau> how to do a G0 command?
[23:57:59] <andypugh> Or G2, G3 which mean move at feed speed, in curves.
[23:58:26] <andypugh> MDI tab, type G0 X100 Y100 (or smaller numbers for an inch machine)
[23:58:36] <atom1> G0 X1, Y1, F50
[23:58:48] <landau> i use unipolar stepper motors....stepgen type is set to 9
