[00:00:05] <JT-Shop> Tn M6 G43 works for me for tool change
[00:00:17] <Tom_itx> http://linuxcnc.org/docs/html/gcode.html
[00:00:24] <Thadius> thanks
[00:00:36] <JT-Shop> and http://linuxcnc.org/docview/html/gcode/tool_compensation.html
[00:01:12] <asdfasd> there is no halui
[00:01:28] <Tom_itx> JT-Shop, where did the RS274NGC_33a.html move to?
[00:01:52] <JT-Shop> asdfasd, http://linuxcnc.org/docview/html/config/ini_config.html#_hal_section_a_id_sub_hal_section_a
[00:02:01] <JT-Shop> Tom_itx, what is that?
[00:02:13] <Tom_itx> gcode reference i believe
[00:02:24] <JT-Shop> the quick reference?
[00:02:40] <JT-Shop> http://linuxcnc.org/docview/html/gcode.html
[00:02:41] <Tom_itx> http://www.linuxcnc.org/handbook/RS274NGC_3/RS274NGC_33a.html
[00:02:46] <Tom_itx> that's where it used to be
[00:03:28] <JT-Shop> I don't recall that document at all
[00:03:39] <JT-Shop> must be very old
[00:04:02] <JT-Shop> this one? http://linuxcnc.org/docview/html/gcode/rs274ngc.html
[00:04:04] <ReadError> cant you just use one of those centering things
[00:04:11] <ReadError> and get it lined up on a point of origin
[00:04:12] <asdfasd> now halui loaded
[00:04:31] <Thadius> i love when you tell someone what you're doing, ie...cnc work, and they get all excited and say "oh really?!! I could do that, you should show me whats involved" and then watch as the wind leaves their sails :)
[00:04:51] <Thadius> as you try to explain to them the process
[00:04:53] -!- mozmck [mozmck!~moses@client-] has joined #linuxcnc
[00:05:03] <JT-Shop> asdfasd, you can put MDI commands in the INI anc call them with a pyvcp button http://linuxcnc.org/docview/html/config/ini_config.html#_halui_section_a_id_sub_halui_section_a
[00:05:04] <Tom_itx> JT-Shop looks ike it
[00:05:22] <ReadError> Thadius: i need a good tutorial ;(
[00:05:25] <JT-Shop> which one LOL
[00:05:27] <ReadError> i got the mill ordered
[00:05:32] <ReadError> about to order the motors
[00:05:38] <ReadError> but have never done anything in cad yet ;((
[00:05:47] <Tom_itx> JT-Shop, err no, that's not the complete one i don't think
[00:05:55] <JT-Shop> you don't need cad
[00:06:07] <JT-Shop> Tom_itx, that's it afaik
[00:06:19] <Tom_itx> the other one listed the memory offsets for G54 etc
[00:06:26] <JT-Shop> some trimming and reordering has gone on since 2.4
[00:06:35] <JT-Shop> oh wait
[00:07:09] <ReadError> jepler
[00:07:11] <ReadError> er
[00:07:14] <JT-Shop> they have been combined to one place http://linuxcnc.org/docview/html/gcode/overview.html
[00:07:19] <ReadError> JT-Shop: i need something to mock up my parts dont I/
[00:07:19] <Thadius> ReadError, i havent found one all encompassing piece of internet gold for learning what little i have, took/takes a lot of work
[00:07:51] <JT-Shop> ReadError, well it depends on the parts really
[00:08:08] <ReadError> JT-Shop: mostly "routing" work
[00:08:11] <ReadError> nothing too 3d intensive
[00:08:17] <ReadError> cutting CF parts and such
[00:08:27] <ReadError> same depth
[00:08:42] <Tom_itx> JT-Shop, so 5221 would be the G54 offset for x?
[00:08:44] <JT-Shop> you can use qcad to draw that out then
[00:08:53] <Tom_itx> 5222 - Y
[00:08:54] <Tom_itx> etc
[00:09:23] <Tom_itx> does that apply to most standard fanuc controls?
[00:09:27] <JT-Shop> they are in order (X Y Z A B C U V W)
[00:09:57] <Tom_itx> so if you call up the 5221 address it will hold the G54 X offset value
[00:10:30] <JT-Shop> yep #5221 is G54 X
[00:11:12] <djdelorie> ok, two drill bits later, lessons learned: 30 IPS is too fast a drill feed, not because of the drill, but because the carriage wobbles, and 50 thou is not enough clearance for XY travel
[00:11:17] <djdelorie> http://www.delorie.com/photos/cnc/drilltest-cnc-015.html
[00:11:27] <JT-Shop> Tom_itx, I guess you might have to ask on the fanuc channel that question lol
[00:11:37] <djdelorie> also, backlash compensation is needed. Top: no compensation, bottom: with 30 thou compensation
[00:11:55] <Tom_itx> JT-Shop, well we had some controls you had to enter the offset that way
[00:12:00] <Tom_itx> or at least edit it
[00:12:10] <Tom_itx> i think you could have the G54 in the code
[00:12:15] <JT-Shop> 30IPS = 1800IPM yea that is fast
[00:12:23] <djdelorie> sorry, 30 IPM
[00:12:23] <Tom_itx> but you set the memory location from the machine coordinate system
[00:12:30] -!- ysli has quit [Quit: Leaving]
[00:12:37] <djdelorie> why are there two standards for specifying feed rates? :-P
[00:12:45] <JT-Shop> 30 IPM is pretty fast for drilling anything but butter
[00:12:58] <Tom_itx> or air after the bit breaks
[00:13:01] <JT-Shop> Tom_itx, sounds confusing
[00:13:08] <JT-Shop> yea
[00:13:12] <djdelorie> I got 130 holes before it snapped :-)
[00:13:52] <JT-Shop> maybe you wore the bit out
[00:14:02] <djdelorie> could be
[00:14:25] <djdelorie> is there a way to pick up a gcode program in the middle, if you have to stop, change bits, and back up a few missed holes?
[00:14:52] <JT-Shop> run from line in Axis
[00:15:27] <djdelorie> ah, in the Machine menu. Thanks
[00:15:53] <djdelorie> I tend to hit stop or estop when I need to pause it, too, that will help :-)
[00:15:56] <JT-Shop> yep or right click I think
[00:16:10] <JT-Shop> http://linuxcnc.org/docview/html/gui/axis.html#_menu_items
[00:16:12] <djdelorie> yep, that too
[00:16:49] <djdelorie> is there a signal in hal connected to "program running" ? I know about the charge pump signal, is that what I want, or is that just "machine on" and not "run" ?
[00:17:11] <JT-Shop> asdfasd, you can add a pyvcp button on the right side
[00:17:38] <JT-Shop> or you would have to change the code for Axis
[00:18:14] <JT-Shop> djdelorie, http://linuxcnc.org/docview/html/man/man1/halui.1.html
[00:18:15] -!- stevegt_1 has quit [Ping timeout: 265 seconds]
[00:18:46] <djdelorie> halui.program.is-running is probably it
[00:23:56] <asdfasd> JT-Shop can you read personal messages?
[00:24:28] <JT-Shop> yes
[00:25:06] <JT-Shop> djdelorie, open up Show Hal and put the pins your interested in a watch window to see what the behavior is
[00:25:21] <asdfasd> I sent you personal but no answer
[00:26:05] <JT-Shop> I replied in here as it is better to discuss linuxcnc on this channel
[00:27:27] <JT-Shop> someone other than myself may have a better answer
[00:27:45] <asdfasd> Im sorry too many people I though better not to mess with other questions
[00:28:55] <asdfasd> I found /usr/bin/axis it looks like here is programmed the function of touch off button, but I cant see where is created the button
[00:30:19] <asdfasd> vars.current_axis.get()
[00:30:38] <jdhnc> work offset question. I have two gcode files for a part, one engraves with a v cutter, one cuts out with an end mill. I want to make 5 sets of these by doing all the engraving, then changing tools and doing all the cutouts. Any good references or sample code?
[00:31:18] <Tom_itx> offest?
[00:31:29] <Tom_itx> G54 for one operation and G55 for the next
[00:31:30] <JT-Shop> asdfasd, I'm not quafied to talk about the inner workings of axis.py
[00:32:04] <Tom_itx> jdhnc, or is that just a tool offset?
[00:32:06] <JT-Shop> jdhnc, sample code to do what?
[00:32:06] <Tom_itx> change..
[00:32:35] <jdhnc> JT: do multiple cuts of the same code, offset by N inches
[00:34:03] <Tom_itx> set it up as a macro?
[00:34:10] -!- Radium has quit [Remote host closed the connection]
[00:34:11] <JT-Shop> jdhnc, you can set your tool lenght for tool 1 cut then set the tool lengh offset for tool 2 then cut
[00:34:34] <Tom_itx> i'm not sure i get what you're after
[00:34:36] <JT-Shop> or just just G54 for one tool and G55 for the second
[00:34:38] -!- Radium [Radium!~carbon@] has joined #linuxcnc
[00:34:43] <JT-Shop> nor am I
[00:35:09] <Tom_itx> i think he want's to engrave 5 sets then do the cutouts
[00:35:18] <Tom_itx> set the cuts up as a macro
[00:35:27] <Tom_itx> offset whatever x or y number you need
[00:35:40] <Tom_itx> i've not done macros but that sounds reasonable
[00:35:48] <jdhnc> I have one file that engrave, one that cuts (change tool between runs). I want to be able to run the first one (to engrave) 5 times, offset by N inches, then go back and run the one that cuts out 5 times.
[00:36:27] <Tom_itx> maybe someone can step you thru setting up a macro with an x y offset
[00:36:35] <Tom_itx> that would do it
[00:36:40] <Tom_itx> one for each tool
[00:36:59] <Tom_itx> err subroutine i mean
[00:37:32] <Tom_itx> what offset do you need?
[00:37:47] <jdhnc> probably just x + 1.5
[00:38:19] <Tom_itx> like i said, i haven't done subroutines simply because i have a cad cam package and do it there but that would do it
[00:38:46] <Tom_itx> set your cuts up in the sub and call it with the x y values incrementing them as you loop x times
[00:38:53] <Tom_itx> (5) in your case
[00:39:06] -!- sumpfralle has quit [Quit: Leaving.]
[00:39:09] * jdhnc reads some more.
[00:39:39] <Tom_itx> see if there's a subroutine example
[00:41:01] phantone is now known as phantoxe
[00:41:03] <Tom_itx> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?SubroutineSample
[00:41:09] <Tom_itx> jdhnc ^^
[00:41:12] <Tom_itx> maybe
[00:41:37] <Tom_itx> naw that's not that good of an example
[00:41:45] <jdhnc> I can do subroutines, I am just somewhat confused about changing fixture offsets in code.
[00:42:26] <Tom_itx> if you just want a different fixture offset change the G54 to G55 G56 etc
[00:42:34] <Tom_itx> and enter their values in the offset table
[00:42:55] <Tom_itx> then call them when needed
[00:43:26] <Tom_itx> that's common for doing multiple steps on a part with say 2 vises or fixtures
[00:44:28] <Tom_itx> with the sub, you wouldn't need that
[00:44:44] <Tom_itx> just loop 5 times and enter a new X offset each time
[00:46:26] <JT-Shop> or use a G92 offset, I do that on my plasma
[00:46:36] <Tom_itx> jdhnc, have a look at this: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Oword#Sample_5_Subroutine_for_generating_multiple_parts_using_Local_and_Global_coordinates
[00:46:54] <JT-Shop> yea Tom_itx to the rescue
[00:47:29] <Tom_itx> i just copy the part in my cad package before i post the gcode :)
[00:47:44] <Tom_itx> and sort the tools the way i want them
[00:47:46] <jdhnc> that looks perfect, thanks.
[00:48:05] <jdhnc> mine makes me do each toolpath by hand
[00:48:11] <jdhnc> or at least, semi-by-hand.
[00:48:19] <Tom_itx> sometimes that's kinda handy
[00:48:57] <Tom_itx> subs make for shorter program files

[01:07:04] -!- ries [ries!~ries@] has parted #linuxcnc
[01:14:11] <djdelorie> JT-Shop: is-running wasn't it. It doesn't activate when homing or jogging
[01:14:51] <djdelorie> Background: my controllers can't quite keep the motors dead-on-target, I'm looking for a signal to tell them it's ok to let the motors drift a little because the machine is not doing anything at the moment
[01:14:51] <JT-Shop> no, I think it is only on when a program is running
[01:15:04] -!- ries [ries!~ries@] has joined #linuxcnc
[01:15:25] <JT-Shop> hmmm
[01:15:30] <djdelorie> current, I hook estop. I was going to hook machine-on instead, but I figured if there was something that automatically shut off the motor drive when the program ended, that would be better
[01:15:50] <JT-Shop> servo?
[01:15:55] <djdelorie> yup
[01:16:13] -!- ries has quit [Client Quit]
[01:16:22] <djdelorie> they can track their location even when the drive power is off, and restore position when needed
[01:16:24] -!- ries [ries!~ries@] has joined #linuxcnc
[01:16:34] <JT-Shop> machine power should turn the amps off
[01:16:49] <djdelorie> yeah, I know about that one. But the machine doesn't "shut off" when the program ends
[01:16:54] <djdelorie> or does it?
[01:17:33] <JT-Shop> no the machine power is still on at the end of a program
[01:17:54] <djdelorie> I couldn't find a pin that meant "I'm jogging" either
[01:18:05] <JT-Shop> halui.machine.off bit in
[01:18:05] <JT-Shop> pin for setting machine Off
[01:18:38] <djdelorie> that would be really annoying, having to keep turning the machine on all the time ;-)
[01:18:45] <JT-Shop> must be a big problem to go to all this trouble
[01:19:03] <djdelorie> no, just annoying. The motors make a subtle buzzing sound when they should be idle
[01:19:21] <JT-Shop> maybe your not don't tuning them
[01:19:23] <djdelorie> yes, I know, "fix the pid loop" but the encoder position is quantized
[01:19:38] <djdelorie> it's buzzing between 0 and +1 for example
[01:20:05] <JT-Shop> are you talking about the DRO reading?
[01:20:20] <djdelorie> I've got them tuned as best as my software allows - the controllers have their own "dro" console
[01:23:59] * JT-Shop heads inside
[01:24:01] <djdelorie> hmmm... perhaps a filtered version of motion.current-vel ?
[01:24:05] <JT-Shop> good luck

[01:52:49] <jdhnc> so, g92 seems very confusing.
[01:53:15] <djdelorie> asdfasd: did you mean "root" ?
[01:53:22] <djdelorie> there's no "administrator" in Linux
[01:55:20] <asdfasd> in users and groups settings is shown as administrator
[01:55:27] <asdfasd> probably mean root
[01:55:50] <asdfasd> actually I want to edin one read only file
[01:56:10] <asdfasd> I just tried that: sudo chmod 666 file.odt
[01:56:14] <djdelorie> there's a good chance, the right thing to do is copy the file to a local directory, and edit the copy
[01:56:38] <asdfasd> I edit the copy but I cant copy over the original
[01:56:45] <djdelorie> what's the file?
[01:56:59] <djdelorie> odt is a spreadsheet, but who's spreadsheet is it?
[01:57:03] <asdfasd> axis.tcl
[01:57:22] <asdfasd> this is the actual file

[01:57:47] <djdelorie> I don't know if that's an overridable file, so what you probably want is "sudo vi axis.tcl" (or some other editor, like emacs or gedit)
[01:58:10] <djdelorie> it's bad practice to leave a system file writable by everyone; that's how virii get in
[01:58:56] <asdfasd> ops
[01:58:59] <asdfasd> I made it
[01:59:07] <asdfasd> now is 666
[01:59:18] <asdfasd> but I dont know the previous permisions
[01:59:48] <asdfasd> how to return the previous permisions after I finish
[01:59:57] <djdelorie> what were they?

[02:05:06] <Thadius> just curious, anyone have any links to their works handy?
[02:05:45] <alex4nder> like, the m achines running, or things they've made?
[02:06:32] <Thadius> both actually :)
[02:07:02] <alex4nder> http://www.andern.org/alexander/taig_milling_wood.m4v <- that's the one I show everybody
[02:07:03] <ReadError> lets see some videos and work alex4nder:)
[02:07:11] <alex4nder> http://www.andern.org/alexander/taig.m4v
[02:07:14] <alex4nder> and that's the setup
[02:07:16] <djdelorie> Thadius: my results for today so far: http://www.delorie.com/photos/cnc/drilltest-cnc-015.html
[02:07:24] <ReadError> i seen those 2
[02:07:39] <djdelorie> (bottom includes backlash compensation)
[02:08:05] <ReadError> are they supposed to be even?
[02:08:11] <alex4nder> djdelorie: is that some random copper plate?
[02:08:21] <djdelorie> it's a blank PCB
[02:08:23] <alex4nder> ah
[02:08:30] <djdelorie> I was testing drilling configs
[02:08:35] <alex4nder> yah, copper is gummy/messy
[02:08:48] <ReadError> what causes some of them to look off?
[02:08:49] <djdelorie> the net result was 10 IPM max, and yes, I need backlash compensation
[02:08:59] <djdelorie> my cnc machine is made of plywood, it wiggles
[02:09:06] <jdhnc> tom_itx: g55 offsets seem to work good, thanks
[02:09:08] <ReadError> ohh
[02:09:09] <djdelorie> the top grid is "full wiggle mode" :-)
[02:09:27] <alex4nder> djdelorie: you're going to have the most advanced control system, with a sillyputty worksurface
[02:09:28] <ReadError> alex4nder: you need backlash compensation?
[02:09:34] <djdelorie> the pattern is: each *diagonal* is drilled in sequence, alternating directions, to maximize the backlash
[02:09:40] <alex4nder> ReadError: everyone could use a little
[02:10:06] <ReadError> ill probably try with your config first
[02:10:11] <ReadError> and see where i need to change stuff
[02:10:18] <alex4nder> you do that
[02:10:22] <Thadius> tomorrow i order my v90
[02:10:24] <djdelorie> alex4nder: this machine is the "learning machine" so that's the idea. The same electronics and software will be used in the next machine, which hopefully will be more physically robust
[02:10:35] <ReadError> Thadius: PICS PICS PICS
[02:10:37] <alex4nder> djdelorie: yah, it's a reasonable thing to do
[02:10:40] <ReadError> i been wanting to see some good ones of that
[02:10:43] <djdelorie> but really, today's stuff was all in gcode anyway
[02:10:57] -!- atom1 has quit [Quit: Leaving]
[02:11:06] <djdelorie> I'm working on an excellon to gcode converter
[02:11:07] <Thadius> oh i'll have pics and video, from assembly to test
[02:11:22] <ReadError> niiice
[02:11:33] <ReadError> that was one i was seriously looking at for routing
[02:11:35] <alex4nder> djdelorie: I think the next change I make is a spindle modification,,.. and then it's on to servos.
[02:11:41] <alex4nder> with better control
[02:11:59] <ReadError> how much more is a servo setup
[02:12:02] <ReadError> vs stepper
[02:12:27] <alex4nder> djdelorie: are you planning on doing motion control/kinematics on your boards or keeping that under Linux?
[02:12:32] <alex4nder> ReadError: 3 times?
[02:12:36] <alex4nder> for a reasonable setup
[02:12:45] <alex4nder> obviously you can go more or less.
[02:12:46] <ReadError> ah wow
[02:12:54] <djdelorie> linuxcnc is managing the path generation. My controllers just keep the motors where linuxcnc tells them to be
[02:12:55] <alex4nder> but your problems aren't going to be that you don't have servos.
[02:13:02] <alex4nder> djdelorie: sure, but what's your long term plan
[02:13:09] <djdelorie> "have fun"
[02:13:16] <alex4nder> ... I mean for your software architecture
[02:13:31] <djdelorie> the controllers simulate steppers, I was going to leave them like that

[02:14:33] <ReadError> any reason?
[02:14:42] <djdelorie> so far, the only $$ I've spent has been on the electronics
[02:15:05] <alex4nder> there's always a bigger machine.. but you plateau on your control electronics pretty quickly
[02:15:15] <djdelorie> and I write GCC ports for a living, and have a degree in electrical and computer engineering, so the electronics is the part I'm best at anyway
[02:15:31] <djdelorie> it doesn't cost money to change software :-)
[02:15:39] <alex4nder> yah
[02:15:49] <alex4nder> and you don't have to rewire. :/

[03:23:49] <alex4nder> joe9: you milled anything yet?
[03:24:32] <joe9> alex4nder: no, reading up on gcode. next step: write and use a simple gcode to measure backlash using a dial indicator.
[03:25:36] <joe9> so, linuxcnc is a Fanuc dialect, correct?

[03:27:36] <joe9> no, I plan on doing something on wood or plywood. learn more.
[03:27:43] <joe9> before embarking on milling pcb's.
[03:28:12] <joe9> I have a lot to learn: gcode, how to clamp stuff down, touch-off's, homing or limit switches
[03:28:16] <alex4nder> well I commend you being thorough.
[03:28:30] <joe9> learn them and then go pick up the pcb stuff.
[03:28:39] <joe9> is there anything that I need to add to the list?
[03:29:43] <alex4nder> you're going to end up learning to mill fixtures for your PCB

[03:35:28] <djdelorie> added software debouncing to my limit switches, homing works flawlessly now :-)
[03:35:50] <djdelorie> JT-Shop: I got the "machine active" logic figured out, url in a moment...
[03:35:59] <joe9> djdelorie: cool. I want to add limit switches and homing too in the next day or so.
[03:36:15] <djdelorie> I'm using the "everything on one pin" configuration
[03:36:21] <asdfasd> finally added separate button for touch off Z
[03:36:29] <alex4nder> asdfasd: what're you touching off of?
[03:36:30] <joe9> i use steppers though.
[03:36:36] <djdelorie> there's a trick to getting the home+limit+range+etc working right
[03:37:11] <djdelorie> the hardware equivalent to what I did is a switch and cap to ground, and a pullup. I.e. it goes active immediately, but there's an 0.1 sec delay to go inactive
[03:37:13] <asdfasd> Im touching always wrong axis, so I added button for Z only
[03:37:18] <djdelorie> ;-)
[03:37:29] <alex4nder> asdfasd: oh, in software.
[03:37:39] <joe9> djdelorie: good idea.
[03:38:04] <asdfasd> I edit several files finally working, such a headache
[03:38:04] <djdelorie> I looked at the debounce module, but it was symmetrical, and I didn't want a delay on *hitting* the limit
[03:38:55] <joe9> djdelorie: what was your cap and pullup ratings?
[03:39:01] <joe9> s/was/is/
[03:39:05] <djdelorie> like I said, I did it in software
[03:39:09] <joe9> oh, ok.
[03:39:24] <djdelorie> there's an 0.1 sec delay timer that's reset whenever the limit logic is active
[03:39:50] <djdelorie> should be do-able in a HAL component too though
[03:39:51] <joe9> is that a plugin to linuxcnc or is it gcode?
[03:40:01] <djdelorie> it's in my firmware
[03:40:13] <joe9> oh, in the driver code?
[03:40:21] <djdelorie> in the RX62T chip :-)
[03:40:33] <joe9> ok, makes sense.
[03:41:07] <djdelorie> the controller lets you mix physical switches and map them to one of two output limit pins; the debounce is done on the output pin, not the switches
[03:44:51] <djdelorie> http://www.delorie.com/cnc/machineactive.comp
[03:47:55] <djdelorie> side effect - the debounce timeout means you can now *see* the axes back off during homing :-)
[03:49:40] <Thadius> quick question, 2.5d is just essentially z axis goto, cut depth, on to next...while 3d when cutting is the ability to move along x and y while having z constantly adjusting positioning based on gcode/project?
[03:49:58] <alex4nder> basically
[03:50:08] -!- asdfasd has quit [Ping timeout: 240 seconds]
[03:50:18] <alex4nder> but 2.5D is not always just a 'goto', depending on your cutting strategy
[03:50:45] <alex4nder> like, you can start pocketing with a spiral Z drop
[03:52:26] <Thadius> i see, however 2.5d does not = something like a face carved into or out of a piece of wood, so to speak
[03:54:07] <alex4nder> eh, it's kind of vague
[03:54:16] <alex4nder> you couldn't do a sphere and have it be 2.5D
[03:54:27] <alex4nder> but you could probably do half a sphere, and it would qualify.
[03:54:28] * djdelorie thinks 2.5D means "anything you can do with a generic XYZ 3-axis mill"
[03:54:50] -!- mozmck has quit [Quit: Leaving.]
[03:56:43] <Thadius> so something of this nature is doable with 2.5 Cam software? http://www.designscomputed.com/coin_pics/amero_20_2007_circ.jpg
[03:57:21] <djdelorie> probably depends on the specific cam (did you mean cad?) software
[03:58:03] <alex4nder> Thadius: a lot of "2.5D CAM software" would be able to do each of those faces.
[03:58:57] <alex4nder> some is going to be better than others
[03:59:33] <Thadius> i meant CAM, and i'm just trying to secure my peace of mind as to which CAM software i go with
[03:59:48] <alex4nder> what're you looking at so far?
[04:00:08] <Thadius> Cambam, and the Vectric cut2d/cut3d
[04:00:14] <alex4nder> ah
[04:00:24] <Thadius> i'm just curious about the cut2d/3d
[04:00:30] <alex4nder> good news is that you can try both out
[04:01:21] <Thadius> ya, i have cut2d, guess i should design up something that more resemble the link i posted
[04:01:51] <Thadius> i was just happy to import my basic designs and have cut2d path them, and then do what i wanted in the preview
[04:03:29] <alex4nder> that reminds me: cambam is out for linux now
[04:03:32] <jdhnc> it's pretty nifty for what it does.

[04:34:20] <mrsun> cant remember :P
[04:34:57] <jdhnc> I can add all that to the program. I wanted to be able to jog Z and touch off after manually changing the tool
[04:37:32] <djdelorie> jdhnc: I asked that a few days ago, there wasn't an obvious solution. I changed my scripts to produce separate gcode files for each tool
[04:39:33] <mrsun> but if you do a tool change in the gcode linuxcnc goes to the tool change position and stops the spindle and waits for UI input ?
[04:42:51] <mazafaka> mrsun: m3 (clockwise) and m4 (counter-clockwise) start to rotate the spindle in different directions
[04:43:07] <mrsun> ahh yes =) so its M5 then =)
[04:43:57] <mazafaka> I do not know the tool changing routine.

[05:03:19] <Jymmm> Rrrrrrrrrrrrrrrrrrrrhjjshhggggggggggggh
[05:03:52] <Thadius> when i configured and set home for each axix at 0.0 when linuxcnc asks me to home, what essentially is it asking for? that i verify all positions are at my set home locations?
[05:04:35] <Jymmm> do you have homing switches?
[05:05:35] <Thadius> i do not
[05:05:54] <Thadius> plan to install limit switches, but entirely different
[05:05:55] <Thadius> no?
[05:06:06] <Jymmm> correct
[05:06:26] <Jymmm> thought some wire them so the server both purposes
[05:06:53] <Jymmm> Realize that 0.0 is not necessarily the HOME position.
[05:07:09] <Jymmm> it could be a relative one, not absolute.
[05:07:23] <Jymmm> It could be an offset of something else.
[05:07:27] <Thadius> well in my config for "home location" thats what I put in for each axis.
[05:07:59] <Thadius> so when its asking me to "home" what essentially does it want? is it related to machines with homing switches only?
[05:08:15] <Jymmm> what is asking you to home?
[05:08:43] <Thadius> before starting a project in linuxcnc, it says you must home before starting
[05:09:37] <Jymmm> Right, so you move your axis to a starting position, or HOME.
[05:09:47] <Jymmm> axises (plural)
[05:09:51] <Jymmm> bbl
[05:09:55] <Thadius> ok, thanks
[05:12:08] -!- factor has quit [Ping timeout: 240 seconds]
[05:15:03] <djdelorie> Thadius: Homing just tells linuxCNC where the axis is *physically* relative to the physical limits of its motion
[05:15:38] <djdelorie> it's "go in this direction until you see this signal, then you'll be at this known position in the A..B physical range"
[05:16:21] <djdelorie> that way, linuxcnc can avoid breaking your new toy by driving it off the end
[05:17:51] <KimK_ibmlaptop> Thadius: As you plan your home switches (& limit sws, if used), the Integrator Manual homing section may be helpful: http://www.linuxcnc.org/docview/html/config/ini_homing.html

[05:27:59] <Tecan> if i click invert on pin 10 it works but the homing goes the opposite direction
[05:28:14] <Tecan> the homing is inverted too ...
[05:28:54] <djdelorie> in a default "home" operation, it goes forward until the switch is "activated", then backs off until the switch releases, then goes forward slower until activated
[05:29:26] <djdelorie> home direction is controlled by the sign of the "homing speed" value

[05:40:47] <Tecan> aha :)
[05:40:49] <djdelorie> most switches have a "hysteresis" so the close and open positions are not the same; that option decides which position is "home"
[05:41:57] <djdelorie> also, one edge might be more reliable. In my system, the debounce software means that only closures are predictably located

[07:54:30] <Jymmm> archivist: it has to roll up and be stored in the cook pot
[07:54:42] <Loetmichel> just without the screw-on-lid ;-)
[07:54:58] <Jymmm> Loetmichel: Yes, there are LOTS of beer can stoves of various designs, they are different.
[07:55:05] <archivist> you dont roll up metal
[07:55:53] <Loetmichel> archivist: oh, i can think of a pot sand made of 0,2mm stainless that could be rolled up...
[07:55:58] <archivist> unless its withing its elastic limit, ie a spring
[07:56:10] <Loetmichel> or stored flat and rolled up to do its job
[07:56:26] <Loetmichel> s/sand/stand
[07:57:24] <Jymmm> click on video http://www.traildesigns.com/stoves/caldera-cone-system
[07:58:57] <Loetmichel> yeah, thats the way i thougt of
[07:59:43] <Jymmm> Loetmichel: What I'm TRYING to tell you, is yes they sorta kinda "look" the same, but they are all different.
[08:00:17] <Jymmm> vise grips, channel locks, needle nose are all "pliers", but they are not the same.
[08:01:23] <Loetmichel> if i understand it right the burner in your picture works by heating up the rim with its flame, thereby heating the center reccess which in course heats up and vaporizes the fuel
[08:01:47] <Loetmichel> so the soda can burners work on the same principle as the one you showed, thats what i meant
[08:02:15] <Jymmm> Again, they are not the same. There are even big differences on the soda can stoves.
[08:02:27] <Loetmichel> yes, i've seen
[08:02:50] <Loetmichel> i dont want to annoy you so lets say you are right ;-)
[08:03:18] <Jymmm> *sigh*
[08:03:45] <Loetmichel> ;-)
[08:04:49] <Loetmichel> dont take me TOO seriously, i dont do myself ;-)
[08:05:23] <Jymmm> Loetmichel: Well, you were trying to simplify it a little too much is all.
[08:06:25] <Jymmm> Having made three different soda can stove designs, they are NOT all the same.
[08:07:06] <Jymmm> I wouldn't want someone to think that they are all the same, get/make one and be disappointed.
[08:08:54] <Jymmm> Oh, and for the record.... When they say that burning wax is non-toxic, they lie and can kiss my ass!

[12:34:57] <jthornton> thanks reading them now
[12:36:27] <Jymmm> jthornton: The simplest is rsync, as it just works. But if you delete/change a file and go to retrieve the original three months ago, you'll only have the latest version.
[12:37:13] -!- syyl [syyl!~syyl@p4FD15C3D.dip.t-dialin.net] has joined #linuxcnc
[12:37:15] <Jymmm> Speculating that you've seting rsync on a daily/weekly basis that is.
[12:37:33] <jthornton> at least the latest version would normally be ok I guess
[12:37:53] <Jymmm> Yeah, something is better than nothing at all.
[12:38:44] <Jymmm> rdiff-backup is the alternative, then you CAN have that 3 moth old original, and the current revissed file
[12:39:05] <jthornton> mainly I'm interested in backing up my configs and subroutines automagicly
[12:39:57] <joe9> i use rsync for backing up the full machine. I am thinking about using a git repo for the backup.
[12:40:41] <joe9> jthornton: rsync and check out the exclude file. it can contain all the dirs/files that you do not want backed up.
[12:41:05] <jthornton> reading this now http://everythinglinux.org/rsync/
[12:41:17] <joe9> jthornton: if it is configs, then git is not a bad idea too. for my configs, i git the directory.
[12:41:32] <joe9> and, then rsync the root filesystem to a storage location
[12:41:37] <joe9> that is what I have now.
[12:41:55] <joe9> I am thinking of putting the root filesystem on git. not sure if that is a good idea though.
[12:42:42] <Jymmm> jthornton: Since rsync can use ssh, you don't need a "server" or daemon. A cron job as simple as rsync -r source destination would work.
[12:42:53] <joe9> too much duplication as I already git the important directories and files anyway.
[12:43:37] <jthornton> Jymmm, what is the syntax for the source over the lan?
[12:43:45] <Jymmm> the same
[12:44:41] <joe9> the "CNC Programming Handbook" by Peter Smid is a pretty extensive book.
[12:45:15] <joe9> it seems like a bible. anyone read it?
[12:45:18] <jthornton> say I have a computer named Plasma with an EMC2 directory what would the syntax be for that?
[12:45:38] <asdfasd> anyone good in HAL ?
[12:45:49] <jthornton> just ask the question
[12:46:07] <joe9> jthornton: there are some good examples online. i doubt it is simple enough to cover it in the chat.
[12:46:28] <joe9> the basic syntax is "rsync <ssh options> source destination"
[12:46:51] <joe9> jthornton: check out the --dry-run, it is very helpful
[12:46:56] <asdfasd> I made a button with pyvcp can I run a function touch_off()
[12:47:16] <jthornton> right, I see that in this tutorial but what is the syntax for the remote source
[12:47:44] <jthornton> or do I just do a pwd after navigating over to there?
[12:48:18] <joe9> jthornton: jthornton@plasma:/home/mine/emc2-dev for source
[12:48:31] <joe9> if you are on the destination
[12:48:40] <jthornton> ok, thanks
[12:49:43] <jthornton> so username@computername:/home...
[12:50:27] <joe9> yes.
[12:50:32] <jthornton> thanks
[12:50:43] <joe9> use --dry-run though
[12:50:51] <jthornton> ok
[12:50:52] <joe9> cannot emphasize that enough.
[12:51:16] <Jymmm> jthornton: READ FIRST http://www.comentum.com/rsync.html
[12:51:40] <Jymmm> jthornton: You CAN fuck up if you screw up the syntax
[12:52:28] <jthornton> ok
[12:54:31] <Jymmm> jthornton: And it's best of you setup and use keys instead of passwords if you want to automate this.
[12:54:44] <jthornton> keys?

[13:00:01] <Jymmm> but can also backup directories, hdd's, etc
[13:01:37] <ReadError> rsync is like a smart scp
[13:01:51] <Jymmm> jthornton: For example. you can have two hdd's in a server. and you daily rsync one hdd to the other. Then you ALWAYS have a 24hour old backup no matter what.

[16:31:55] <joe9> there is no backlash on the X, Y or Z axis with my new taig.
[16:32:31] <joe9> i measured it with a HF dial indicator and moving 5 cm on the axis. is that a good measurement?
[16:32:42] <joe9> or, should I be considering larger distances?
[16:33:56] <Jymmm> Move in a 10cm square 4 times may be better
[16:35:08] <mazafaka> Why not 40 times then?
[16:35:50] <Jymmm> just depends on how anal one may be.

[17:17:29] <joe9> http://groups.yahoo.com/group/taigtools/message/23417?var=1&p=3 is how I measured backlash.
[17:19:25] <IchGuckLive> joe9: are your mashining parts that pricise so you need backlash into the ini
[17:19:55] <joe9> IchGuckLive: my plan is to mill pcb's.

[17:20:07] <joe9> the traces are atleast 15mils
[17:20:11] <IchGuckLive> therfor its not nessesaty
[17:20:23] <joe9> oh, ok. thanks. I did not know that.
[17:20:38] <IchGuckLive> what is your backlash
[17:20:38] <archivist> joe9, it does matter!
[17:21:17] <joe9> i cannot measure backlash with my dial indicator.
[17:21:40] <IchGuckLive> joe9: 0.002inch is good if you got this
[17:21:54] <archivist> joe9, if you have ball screws there should be no measurable backlash
[17:22:02] <joe9> the dial indicator has a granularity of 0.001 inch
[17:22:09] <archivist> IchGuckLive, 2 thou is bad
[17:22:28] <IchGuckLive> archivist: for pcb good
[17:22:50] <archivist> no not good for pcb either imo
[17:23:18] <joe9> this is what I bought https://www.a2zcorp.us/store/ProductDetailNP.asp?Cguid={4C4BECA4-849D-4CA8-ADF4-24E6A8AA98C4}&ProductID=6034&Category=Taig:Mill%20Machine
[17:23:41] <joe9> "Ball bearings in lead screw bearing block, Bronze Leadnuts,"
[17:24:02] <joe9> not sure if those ball bearings are the reason that I am not able to measure backlash.
[17:24:48] <joe9> archivist: immeasurable backlash good, I presume?
[17:24:58] <IchGuckLive> there is no backlash on this mashie
[17:25:00] <archivist> good
[17:25:38] <IchGuckLive> there is also a certificate coming with the mashine backlash messurments
[17:26:04] <joe9> IchGuckLive: i will ask for that.
[17:26:05] <joe9> thanks.
[17:26:12] <IchGuckLive> messured for eatch axis and spindle
[17:26:40] <IchGuckLive> 1K USD nice prise
[17:26:52] <joe9> i measured for the axes. but not the spindle.
[17:27:03] <joe9> X, Y and Z axes.
[17:27:21] <IchGuckLive> so gor fo non backlash in the ini
[17:27:50] <joe9> ok, thanks.
[17:28:04] <IchGuckLive> best to check is in real milling go zig zack L Form with minimal stepover
[17:28:22] <IchGuckLive> joe9: whats your cutter size
[17:28:25] <joe9> ok, thanks.
[17:28:31] <joe9> IchGuckLive: no idea, yet.
[17:30:02] <IchGuckLive> 0.0118 is good for pcb
[17:30:17] <joe9> ok, thanks.
[17:30:32] <IchGuckLive> thats 0.3mm isolation
[17:31:27] <IchGuckLive> good also for manuell resharp under magnifying glass

[21:06:57] <asdfasd> if XY changes definitely have to blame somebody :)
[21:06:58] <djdelorie> and my carriage wobbles in XY if the Z feed is too fast
[21:07:09] <Loetmichel> the smallest i possess are 0,3mm
[21:07:10] <djdelorie> I blame nature for making weak trees :-)
[21:07:40] <djdelorie> 0145 is about 0.37mm

[21:08:18] <asdfasd> my dad always say for the wooden CNC - beware with the woodworms :D
[21:08:57] <djdelorie> I have a tool called a "woodworm" but it's a screw chuck for a wood lathe
[21:09:34] <Loetmichel> my old mill was made from wood also
[21:10:13] <Loetmichel> ... more or less, it was "siebdruckplatte", plywood 20 sheets or so glued with melamine instad of white glue
[21:10:31] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=4935
[21:10:35] <asdfasd> first test on my mill was with dremel not very good, now I have good spindle but I didnt make any PCBs I can find a video with drilling
[21:11:13] <djdelorie> I use a dremel in a drill press for hand-drilling, but the runout on a dremel is pretty high
[21:11:23] <djdelorie> the cnc machine has a 56k rpm air spindle in it

[21:38:05] <Jymmm> JT-Shop: jthornton Have you ever heard of "thermos cooking" before? It's kinda interesting. I tried a couple of things out and not too shabby.
[21:40:08] <Loetmichel> asdfasd: looks like a bnit to wide engraving bit
[21:40:21] <Loetmichel> my last milled pcb:
[21:40:37] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=804
[21:40:50] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=814 (chemically tinned)
[21:41:02] <Jymmm> that's icky! should I look at the photo now?
[21:41:09] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=819 <- other side
[21:41:25] <asdfasd> the bit was fine, but I made wrong settings on the G code generator, it made several passes
[21:41:41] <Jymmm> Loetmichel: looks nice!
[21:42:10] <Loetmichel> the parts pront ist printed mirrored on paper with a leser printer
[21:42:13] <Loetmichel> laser
[21:42:17] <Loetmichel> and then ironed on
[21:43:46] <asdfasd> Jymmm: "thermos cooking" sounds like "student toaster" 1 iron upside-down and you toast your sandwitch on it :)
[21:44:24] <Jymmm> asdfasd: I was able to COOL dried blackeyed peas in the thermos just using boiling water
[21:44:29] <Jymmm> err COOK
[21:44:53] <djdelorie> Loetmichel: toner will stick to the fr4 better if you sand it with 400 grit first; toner doesn't like sticking to smooth surfaces
[21:45:17] <Jymmm> asdfasd: it took 10+ hours, but I didn't have todo anything at all.
[21:45:54] <Loetmichel> djdelorie: tahts ok, fir the parts placement print some missing toner isnt really a drama
[21:46:16] <asdfasd> :)))))) yeah that remind me for my student life, a lots of time and limited posibilites, then people became really inventive :)
[21:46:36] <djdelorie> I know, just mentioning it. Also, knowing that, you learn why you can use transparencies for toner transfer - they're very smooth :-)
[21:46:40] <Jymmm> asdfasd: I tried 1 cup of brown rice at noon, checked it a few minutes ago, and needs maybe another 2hours or so.
[21:47:13] <Jymmm> asdfasd: Well, it's when you have limited fuel, etc
[21:47:43] <Jymmm> asdfasd: But the ease of it if you just plan ahead, seems to work really well.
[21:48:00] <alex4nder> hey
[21:48:39] <Jymmm> asdfasd: or if you go hunting, backpacking, hiking, etc and want a hot meal when you're done.

[21:50:31] <Jymmm> asdfasd: Ah, yeah... just need boiing water and 8+ hours, plus a good thermos or two.
[21:51:01] <Jymmm> asdfasd: I SUCK at cooking rice without a rice cooker, and beans, oh hell, they take forever on the stove.
[21:51:23] <Jymmm> asdfasd: I'm going to try pinto beans next and see what happens.
[21:51:27] <alex4nder> haha
[21:51:28] <alex4nder> beans
[21:51:29] <alex4nder> come on man
[21:51:50] <Jymmm> alex4nder: They are the most difficult things to cook is why I used them as a test.
[21:52:18] <alex4nder> why?
[21:52:41] <Jymmm> alex4nder: Dreid beans take FOREVER to rehydrate, and then cook.
[21:52:44] <Jymmm> Dried
[21:52:51] <alex4nder> you put them in water in the fridge, wait a day or two, and cook

[23:53:48] <Tecan> revolutions per inch... im just not sure yet
[23:54:58] <Tecan> callipers ?
[23:55:23] <asdfasd> you mean for emc settings?
[23:55:31] <Tecan> yes
[23:56:23] <asdfasd> what I did is to calculate my steps per mm on the machine
[23:56:39] <asdfasd> then I setup a screw pitch 1mm
[23:56:50] <asdfasd> and I entered my steps per mm
[23:57:04] <Tecan> 1 revolution = 45 mm
[23:57:35] <asdfasd> how many steps you have to make that 1 revolution
[23:57:52] <Tecan> so leave pully teeth as 1 ?
[23:58:03] <asdfasd> yes
