[00:30:27] <tjtr33> KimK, hello, is the NCL mentioned at Stuart's related to http://www.ncl.ucar.edu/Download/install.shtml ?
[00:30:29] <tjtr33> ( might just be acronym overloading )
[00:32:01] <tjtr33> eh, looks like geo-physical cad, nm
[00:38:13] <Tom_itx> http://www.nccs.com/pages/nccs_home.html
[00:39:35] <KimK> tjtr33: Tom_itx beat me to it, that looks right. Thanks, Tom.
[00:42:35] <Tom_itx> i bet it's $$$ too
[00:42:57] <Tom_itx> i know what i gave for mine 20 yrs ago
[00:50:36] -!- firephoto has quit [Quit: ZNC - http://znc.in]
[01:05:56] <generic_nick> well i guess my 7i48 is still bad, but i got everything else wired up and all servos are holding.
[01:06:23] <generic_nick> which means the drives and motors should be ok i guess
[01:10:07] <generic_nick> temporarily im going to put in the 7i33 so i can at least use the mill until i get my new 7i48 in
[01:10:45] <Tom_itx> there was a problem with the 48?
[01:10:52] <generic_nick> yes
[01:11:15] <generic_nick> power suply or something in it.

[01:25:20] <skunkworks> ssi: actually - I am not 100% sure that will run brushed.. Normally the B's will do both but the spec sheet doesn't say on that one...

[02:44:26] <tjtr33> well i uploaded a deb for apt360 a year back, iirc its for 10.04
[02:47:16] <tjtr33> see Dan Falcks site http://opensourcedesigntools.blogspot.com/2012/06/apt360-websockets-demonstration-apt360.html
[02:47:31] <tjtr33> its a true APT build
[02:48:57] <tjtr33> i cant find the deb now, but Dan drops in here occasionally
[02:53:21] <Connor> okay, so, what's with all the talk about Beagle Boards and Bone's and Pi's on the mailing list.. why do people want to run LinuxCNC on such a lower powered machine ?
[02:54:48] <r00t4rd3d> cost
[02:54:56] <r00t4rd3d> simplicity
[02:55:02] <r00t4rd3d> compact
[02:55:34] <r00t4rd3d> the opposite of your wife
[02:55:40] <r00t4rd3d> :)
[02:55:54] <Connor> They're underpowered to run the GUI are they not ?
[02:56:14] <r00t4rd3d> nah
[02:56:26] <tjtr33> headless i thought, offloading the io handling
[02:56:37] <r00t4rd3d> plenty of light weight gui's
[02:57:36] <r00t4rd3d> The UDOO is what I want to see going

[03:01:59] <gamma-x> ok i cant get any axis' to move on my mill with either linuxcnc or mach3...
[03:02:29] <gamma-x> any thoughts?
[03:02:36] <r00t4rd3d> power or controller
[03:03:13] <gamma-x> everything is getting power...
[03:03:41] <gamma-x> all drives have green light and are wired correctly.... breakout board only has the x axis hooked up currently.
[03:03:44] <r00t4rd3d> guessing or tested with multimeter ?
[03:04:31] <gamma-x> well the steppers are "locked" when the power is on... i can turn it by hand but its in very small incriments as its jutters.
[03:06:01] <r00t4rd3d> did you run stepconf and do the test axis stuff?
[03:06:21] -!- Keknom has quit [Quit: Leaving.]
[03:06:49] <gamma-x> r00t4rd3d, the test axis has been throwin error codes.
[03:07:37] <r00t4rd3d> did you install from the livecd or compile?
[03:07:59] <gamma-x> live cd
[03:08:12] <gamma-x> well... didnt boot into livecd... just installed.
[03:08:13] <r00t4rd3d> did you do the jitter test
[03:08:18] <gamma-x> yeah
[03:08:24] <r00t4rd3d> what was the numbers
[03:08:37] <gamma-x> i want to say 1500 or 15000
[03:08:50] <gamma-x> its a newer dell pc.
[03:09:25] <r00t4rd3d> single axis geckos?
[03:09:47] <gamma-x> chinese kind controllers
[03:09:53] <gamma-x> 7.2 ma860h
[03:09:59] <r00t4rd3d> well theres your problem
[03:10:16] <gamma-x> http://www.ebay.com/itm/CNC-5-Axis-Breakout-Board-3x-MA860H-Stepper-Driver-2-6-7-2A-Nema23-Nema34-Nema42-/251255616577?pt=AU_B_I_Electrical_Test_Equipment&hash=item3a80007441
[03:11:57] <r00t4rd3d> are you guessing what to put in the Parallel Port setup when you run stepconf?
[03:12:37] <gamma-x> for the pins I know whats what according to the schematic atleast...
[03:13:34] <skunkworks> is there a watch-dog or charge pump on the board
[03:13:42] <skunkworks> ?
[03:13:54] <skunkworks> or an enable of some sort?
[03:14:17] <r00t4rd3d> 10 dips
[03:14:28] <r00t4rd3d> err 8
[03:15:06] <gamma-x> skunkworks, I dont know what you mean, There is enable... Thats pin 1
[03:15:08] <r00t4rd3d> is 1 in the up or down position?
[03:15:27] <gamma-x> http://www.savebase.com/infobase/downloads/Breakout_Board_Stepper_Driver/User_Manual_5_axis_Breakout_board.pdf
[03:17:34] <gamma-x> its prolly easier to give you that ^^^ than to try and explain what i think I know.. lol
[03:21:04] -!- skunkworks2 [skunkworks2!~yaaic@str-broadband-ccmts-ws-26.dsl.airstreamcomm.net] has joined #linuxcnc
[03:23:11] <gamma-x> r00t4rd3d, any thoughts? Im baffled at this point! lol
[03:23:11] <r00t4rd3d> have you searched cnczone.com for someone else with that board?
[03:23:21] <gamma-x> not yet
[03:23:52] <r00t4rd3d> i would try to find someone else who has a working setup with that board
[03:24:17] <r00t4rd3d> im sure you have a setting or dip wrong
[03:24:55] <gamma-x> i currently have all the dips in the on position on the drives... maby that why
[03:25:56] <r00t4rd3d> pretty low amps
[03:26:07] <r00t4rd3d> what are your motors rated?
[03:26:11] <gamma-x> 560
[03:26:20] <r00t4rd3d> no for amps
[03:26:40] <gamma-x> wait there all on...
[03:26:43] <gamma-x> uhhh
[03:27:05] <r00t4rd3d> all on would be 2.6a peak and 1.8a average
[03:27:23] <r00t4rd3d> if you have 560oz-in steppers iam sure they require more power then that
[03:27:33] <Tom_itx> that's pretty low for a cnc stepper
[03:28:09] <gamma-x> 570 oz In. Hybrid Motor
[03:28:09] <gamma-x> 1.8° /200 Steps Per Rev.
[03:28:09] <gamma-x> 5 Amps Current Per Phase
[03:28:09] <gamma-x> 4-wire Bi-polar, NEMA 23 Frame
[03:28:15] <r00t4rd3d> lol
[03:28:19] <r00t4rd3d> they want 5amps
[03:28:40] <Tom_itx> if those drivers only put out 2.6a even at peak, they're not big enough
[03:28:55] <gamma-x> drivers put out 7.2A
[03:29:09] <r00t4rd3d> you can set his controller to 7.2a peak and 5.0a avg
[03:29:30] <r00t4rd3d> turn 123 to off
[03:29:41] <r00t4rd3d> well try on off off first

[03:30:30] -!- AndChat|171201 has quit [Read error: Connection reset by peer]
[03:30:55] <gamma-x> that could be my problem....
[03:31:05] <r00t4rd3d> yeah
[03:31:13] <r00t4rd3d> there is no step config for all off
[03:31:16] <gamma-x> there is no all off on those drivers for sw5-sw8
[03:31:36] <r00t4rd3d> turn 5678 on
[03:32:21] <gamma-x> r00t4rd3d, would that be best "resolution"
[03:32:39] <r00t4rd3d> no clue
[03:33:23] <r00t4rd3d> Tom_itx, http://www.gbeshop.com/InfoBase/SAVEBASE/PKG/003000/Image/MA860H_1.jpg
[03:35:38] <r00t4rd3d> those are the dip settings on his board
[03:35:52] <Tom_itx> i'd set the current a bit lower until you get it figured out
[03:37:09] <Tom_itx> and if it's driven from a parallel port you don't want the microstepping too high because the port won't keep up
[03:37:23] <Tom_itx> the mesa cards can because they're externally clocked
[03:38:01] <Tom_itx> the microstepping rate must match your config steps per rev too
[03:38:07] <Tom_itx> in the ini
[03:38:20] <r00t4rd3d> thats probably his issue
[03:38:24] <gamma-x> I am trying to keep it cheap for now so no mesa currently :(
[03:38:30] <gamma-x> unless someone has a used one!
[03:38:36] <Tom_itx> go for a low microstep then
[03:38:40] <r00t4rd3d> should just got a tb6560 :)
[03:38:47] <Tom_itx> mesa and gecko are both awesome
[03:38:58] <r00t4rd3d> really?
[03:39:05] <Tom_itx> i wouldn't trade em
[03:39:28] <r00t4rd3d> gamma-x, you can get the single axis geckos for $60
[03:39:44] <Tom_itx> i got the 203v x 3
[03:39:47] <gamma-x> these drivers.. while chinese are supposed to be realy good
[03:40:04] <Tom_itx> give em a go, just set the current low and the steps low
[03:40:10] <Tom_itx> until you get it going
[03:40:14] <r00t4rd3d> http://www.ebay.com/itm/gecko-g251x-stepper-motor-driver-4-cnc-milling-machine-mill-lathe-router-/160720512970?pt=LH_DefaultDomain_0&hash=item256bb067ca
[03:41:06] <r00t4rd3d> ill be getting those soon to replace my tb6560
[03:41:27] <Tom_itx> i went with individual drivers on mine
[03:41:32] <Tom_itx> instead of the 4 pack
[03:41:42] <r00t4rd3d> cheaper
[03:42:01] <r00t4rd3d> by like 150
[03:42:02] <Tom_itx> the 203 handle more voltage iirc
[03:42:14] <Tom_itx> more voltage means faster step rates
[03:42:37] <jdh> not really
[03:42:43] <Tom_itx> up to a point
[03:42:48] * r00t4rd3d FIGHT!
[03:42:55] <Tom_itx> no
[03:42:55] <jdh> higher step frequency means higher step rates
[03:43:06] <Tom_itx> once the coils saturate you won't get any more from them
[03:43:32] <Tom_itx> jdh, higher voltage allows for that as the chopper reaches peak quicker
[03:43:54] <jdh> semantics perhaps,.
[03:43:58] <Tom_itx> you won't need to worry about optimum on a parallel port anyway
[03:44:09] <jdh> step rate vs. how fast the step steps
[03:44:23] <Tom_itx> same thing just put a different way i suppose
[03:44:48] <FinboySlick> r00t4rd3d: 20 bucks on tom, in the fourth round.
[03:45:08] <jdh> no, if you put out a 10khz pulse stream, it would have a higher step rate than a 1khz pulse train
[03:45:18] <Tom_itx> duh
[03:45:19] -!- skunkworks2 has quit [Ping timeout: 252 seconds]
[03:45:42] <Tom_itx> but the steppers have to be able to keep up with it without loosing steps
[03:46:05] <jdh> sure, but step rate is from pulses, step speed is from voltage
[03:46:07] <Tom_itx> that's where the higher voltage comes in to play as it allows the peak current to peak quicker
[03:46:23] <jdh> not that this is relevant to anything
[03:46:37] <r00t4rd3d> 1,2,3,4...
[03:46:48] <gamma-x> ive heard the keling 570oz steppers fair realy well
[03:47:06] <jdh> gamma-x: I, and connor have them on our G0704s
[03:47:10] <gamma-x> im running 15amp 50-55v PS
[03:47:12] <Tom_itx> gamma-x, are those the nema23's?
[03:47:24] <Tom_itx> that's about what mine is
[03:47:27] <gamma-x> yup, I have a 1200 nema 34 on the z
[03:47:32] <Tom_itx> 50v 18A
[03:47:39] <FinboySlick> On the topic of steppers, I had a question. 5mm pitch ballscrews, 200 step steppers, using um.. 1/4 microstepping, are the facets in my circles due to code or is it just not enough microstepping to make a round seem round?
[03:48:13] <gamma-x> whats better. higher or lower microstepping?
[03:48:28] <jdh> lower is better torque
[03:48:34] <r00t4rd3d> what works
[03:48:35] <FinboySlick> gamma-x: Depends on the torque you want.
[03:48:43] <Tom_itx> i like the geckos because they smooth it all out
[03:48:47] <Tom_itx> they are 10 microstep
[03:48:50] <Tom_itx> no switching
[03:48:51] <jdh> higher is better psuedoresolution and mid-range smoothing

[03:49:51] <r00t4rd3d> most people run 1/2 microstep right?
[03:49:59] <Tom_itx> i'm running 10
[03:50:05] <jdh> fin: 0.0625mm/step. Is that sufficient for your needs?
[03:50:15] <r00t4rd3d> http://www.gbeshop.com/InfoBase/SAVEBASE/PKG/003000/Image/MA860H_1.jpg
[03:50:19] <Tom_itx> so 40000 steps per inch iirc
[03:50:30] <r00t4rd3d> what would 5 6 7 8 be set at for 1/2 ?
[03:50:42] <jdh> on
[03:50:49] <Tom_itx> i closed it
[03:50:50] <r00t4rd3d> 400?
[03:51:15] <jdh> yes
[03:51:25] <r00t4rd3d> gamma-x, try that
[03:51:31] <jdh> assuming you have a normal 1.8° motor
[03:51:36] <gamma-x> I plan on it.
[03:51:38] <r00t4rd3d> and lower the amps
[03:51:52] <gamma-x> lower the amps...
[03:51:52] <r00t4rd3d> and make sure you have stepconf set to 1/2 microstep
[03:52:04] <jdh> keling sells two different 570's. One has oddly low amps
[03:52:22] <FinboySlick> jdh: I might have bee lying. I seem to remember setting microstepping to about 0.02mm/step.
[03:52:28] <gamma-x> I think myne are 5... not sure lemme look
[03:52:40] <Tom_itx> the first one i saw was 5A
[03:52:51] <Tom_itx> in the nema23 package
[03:53:13] <r00t4rd3d> gamma-x, if all your motors are different each controller will have to be set to that motor
[03:53:23] <r00t4rd3d> power wise atleast
[03:53:30] <jdh> what driver?
[03:53:38] <r00t4rd3d> china man

[03:54:45] <FinboySlick> jdh: I was mostly curious to know what step size typically gives you 'can't see the difference' smoothing when it comes to circles. I probably need more variables for that.
[03:55:27] <jdh> the real resolution doesn't really match the math
[03:55:38] <r00t4rd3d> gamma-x, i didnt have any help setting up my board and i could tell just by the sound of my motors i was doing something wrong
[03:55:40] <jdh> other than as step count.
[03:55:51] <gamma-x> r00t4rd3d, lol noted.
[03:56:08] <Tom_itx> just don't blow it up if you're not sure
[03:56:27] <pcw_home> Somewhere around 32 is the point of diminishing returns for noise/vibration elimination

[03:57:31] <gamma-x> r00t4rd3d, should I be lookin at peak or avg?
[03:57:34] <FinboySlick> I'll be able to dedicate the whole basement (and its precious concrete floor) to the mill and other implements of maiming.
[03:57:34] <gamma-x> for amps
[03:57:52] <r00t4rd3d> im new, you should be asking the others :)
[03:58:04] <jdh> I'd have lots of room for my stuff if I could get rid of my wife's car.
[03:58:35] <Tom_itx> gamma-x, i'd set switches 1-3 on on off to begin with.. that's 3.6A
[03:58:53] <Tom_itx> then work your way up to fry
[03:59:05] <gamma-x> Tom_itx, lol how do I know where to stop realistichly?
[03:59:06] <r00t4rd3d> he already had them maxed
[03:59:15] -!- aitek2012 has quit [Read error: Connection reset by peer]
[03:59:30] <Tom_itx> if you can cook on the steppers, they're too hot
[03:59:33] <r00t4rd3d> or wait, miniumumed
[03:59:59] <gamma-x> that is correct. But hopefully becuase of not being able to move them.... no voltage went in! lol
[04:00:02] <Tom_itx> they will get hotter while idle then when running
[04:00:21] <Tom_itx> unless the driver has current idle reduction
[04:00:46] <Tom_itx> another notch in gecko's belt
[04:00:47] <gamma-x> they wernt hot to touch at all
[04:00:56] <tjtr33> if you've not used steppers before: warm & even uncomfortable hot is ok for stepper motors, but hurt hot is nfg
[04:01:12] <gamma-x> tjtr33, good point thanks!
[04:01:23] <Tom_itx> you don't wanna melt the enamel off the wires inside
[04:01:26] <gamma-x> what should I put for sw4?
[04:01:42] <jdh> I have one at work that is ~10 years old. Will cause blisters.
[04:01:51] <Tom_itx> i dunno what that's for
[04:01:59] <jdh> runs off an ancient huge Polyspede driver
[04:01:59] <r00t4rd3d> i think thats like decay mode
[04:02:04] <Tom_itx> jdh, heh
[04:02:08] <jdh> 4 is idle current reduction
[04:02:20] <gamma-x> on is work-full/standstill-full off is work-full/standstill-half
[04:02:29] <Tom_itx> turn it off
[04:02:34] <Tom_itx> for half standstill
[04:02:41] <jdh> off makes the cooler, but less holding torque when idle
[04:02:48] <Tom_itx> that'll reduce heat when they're idle
[04:02:57] <tjtr33> oldies like slo-syns didnt cause blisters, so hurt hot is at the edge of their range
[04:03:09] <jdh> it is an ancient blue slo-syn
[04:03:20] <tjtr33> ah, used loads of those
[04:03:36] -!- tmcw has quit [Remote host closed the connection]
[04:03:37] <Tom_itx> then start with 2 microstep and work your way up
[04:03:39] <r00t4rd3d> for testing wouldnt ON be better then screw with the conservative stuff after its running correctly?
[04:03:56] <gamma-x> jdh, do I really need holding torque? Not sure of the concept...
[04:04:19] <Tom_itx> gamma-x, that's like the idle current reduction i just mentioned
[04:04:27] <jdh> depends on what you are doing. If you are cutting strictly horizontal or vertical, you might need it
[04:05:11] <FinboySlick> gamma-x: A good example of holding torque not doing its job: The head slowly dropping down while milling a horizontal surface.
[04:05:24] <gamma-x> ahhhh
[04:05:38] <gamma-x> well then for the z as it ways a lot I will have that on!
[04:05:40] <Tom_itx> i'd also put a counterbalance on Z
[04:05:57] <gamma-x> Tom_itx, even with a 1200oz?
[04:06:00] <Tom_itx> takes less motor to move it that way too
[04:06:20] <Tom_itx> elevators use em :)
[04:06:32] <Tom_itx> that big mill at Stuart's uses them
[04:06:48] <gamma-x> the thought of it just sounds like lots more work! lol I need to start recouping some money otherwyse my girl is gonna kill me!
[04:07:01] <FinboySlick> Just don't accelerate up past 1G ;)
[04:07:23] <gamma-x> ok so what I have for my x and y so far is on,on,off,off,on,on,on,on
[04:07:41] <Tom_itx> sounds fair for a start
[04:08:05] <Tom_itx> midrange current, idle reduction and 2 microstep
[04:08:21] <gamma-x> yessir
[04:08:46] <gamma-x> id like to have on off off for the amps...
[04:08:53] <Tom_itx> i don't even know what mill this is going on
[04:09:00] <gamma-x> rf45 clone
[04:09:26] <gamma-x> pm45cnc to be exact..
[04:10:05] <Tom_itx> that looks decent
[04:10:12] <Tom_itx> better than what i have
[04:10:31] <gamma-x> for my z I will have off off off on on on on on
[04:11:10] <Tom_itx> i'd turn current reduction on
[04:11:21] <Tom_itx> and try it
[04:11:23] <gamma-x> the z head is super heavy
[04:11:30] <Tom_itx> counterweight
[04:11:32] <Tom_itx> :)
[04:11:37] <gamma-x> dont wanna! lol
[04:11:59] <Tom_itx> keep an eye on heat
[04:12:02] <FinboySlick> gamma-x: Mine uses a pneumatic spring to counter the weight.
[04:12:18] <gamma-x> FinboySlick, what mill you have?
[04:12:21] <Tom_itx> it just makes sense to use one
[04:12:32] <Tom_itx> of some type
[04:12:59] <gamma-x> FinboySlick, you have photos?
[04:13:00] <Tom_itx> it will save wear on the screw and everything else too
[04:13:15] <FinboySlick> gamma-x: One that looks great on paper but left me disappointed in practice :P http://www.syilamerica.com/machine_x5speed.php
[04:13:18] <gamma-x> ive seen some botched jobs in the counterweight dept ...
[04:13:39] <Tom_itx> mine isn't fancy but it's effective
[04:13:54] <FinboySlick> Tom_itx: you mean the sweet little sherline?
[04:14:00] <Tom_itx> heh
[04:14:13] <Tom_itx> yeah and it's counterweight on z
[04:14:19] <gamma-x> lol
[04:14:31] <Tom_itx> big brass bar
[04:14:45] <tjtr33> cable & pulley & weight ?
[04:14:50] <Tom_itx> like 2.5" diameter
[04:14:51] <gamma-x> FinboySlick, pics of the counterspring?
[04:14:54] <Tom_itx> yeah
[04:15:11] <FinboySlick> Tom_itx: Not really, it's hidden on the left side inside the housing I think.
[04:15:31] <Tom_itx> k. i'm out for today
[04:15:38] <FinboySlick> It's in the assembly plans though. Hopefully Chen didn't forget to put it in before lying on the inspection sheet ;)
[04:15:41] <gamma-x> my cabinet is on the back of my machine... idk how id mount a counterweight...
[04:15:55] <tjtr33> makes a diff to the accelerations, w/o counterweight its big diff in Z+ vs Z- accel
[04:16:07] <Tom_itx> sure is
[04:20:32] <Tom_itx> mount a couple gas shocks from a hatchback to the sides :)
[04:20:49] <gamma-x> lol classy!
[04:21:02] <jdh> X2's come with a gas shock
[04:21:08] <jdh> or is it a spring now
[04:21:13] <gamma-x> its an x2! lol

[10:51:00] <maximilian_h> Hello
[10:51:24] <maximilian_h> does somebody know if there is a gcode for mirroring coordinates of an axis ?
[10:51:43] <maximilian_h> because I'd like to replace an old cnc controller
[10:52:08] <jdh> you can rotate axes with G10 L2 P1 R<whatever>
[10:52:12] <maximilian_h> but the cam software, which I cannot replace, gives gcodes that mirror x and y
[10:52:31] <maximilian_h> hello jdh
[10:52:53] <jdh> G10 L2 P1 R90 or R270 would rotate x to y one way or the other
[10:53:16] <maximilian_h> let me have a quick look at the manual
[10:53:23] <maximilian_h> i'll be right back
[10:53:23] <cpresser> maximilian_h: there is a tool which can also perform that task: http://code.google.com/p/grecode/
[10:54:00] <jdh> heh, that looks much easier. the other way confused me to no end when jogging and touching off
[10:56:25] <maximilian_h> neither will work I believe
[10:56:38] <maximilian_h> G10 L2 will not work because it rotates
[10:57:19] <maximilian_h> but if x coordinates stay the way they are and y is mirrored, then it is not a simple rotation
[10:58:11] <maximilian_h> and grecode, which I did not know yet, seems to rotate all coordinates in the cnc program
[10:58:35] -!- Icekiller has quit [Read error: Operation timed out]
[10:58:38] <maximilian_h> however, in my case the x and y axes are mirrored before some subprogram is called
[10:58:58] <maximilian_h> so I cannot apply grecode to the whole program :(
[11:01:16] <maximilian_h> it only has to work in the xy plane, that is in the G17 setting
[11:01:36] <maximilian_h> and only axes x and y are affected
[11:04:11] <maximilian_h> does somebody know where the code for the gcode interpreter that translates G10 resides ?
[11:04:25] <maximilian_h> Because if there is a code for rotation already in place
[11:04:48] <maximilian_h> then adding some mirroring ?might? not be too hard

[11:30:42] <Tom_itx> maximilian_h there was a gcode but all the cutter paths would be wrong
[11:31:12] <maximilian_h> hello Tom_itx
[11:31:35] <maximilian_h> what means cutter paths could be wrong ?
[11:32:03] <Tom_itx> if you mirror it, what was conventional cuts will be climb
[11:32:05] <maximilian_h> and what gcode do you refer to please ?
[11:32:15] <Tom_itx> i don't recall off hand
[11:33:00] <maximilian_h> I could live with the cutter paths, since the cnc controller that I'd like to replace does not have the functionality anyway
[11:33:20] <maximilian_h> do you know who I could ask ?
[11:33:20] <Tom_itx> on a Fadal it was G51.1
[11:33:49] <Tom_itx> and mirror image cancel was 50.1
[11:34:18] <maximilian_h> yes, here it is G39 x1 y1 for mirroring in x and y
[11:34:21] <Tom_itx> probably not implemented in linuxcnc
[11:34:29] <maximilian_h> or G39 x0 y0 to switch it off
[11:34:46] <maximilian_h> too bad if it is not implemented ;)
[11:34:57] <Tom_itx> your cutter paths would be backwards though
[11:35:05] <Tom_itx> we didn't use it much
[11:35:11] <maximilian_h> do you happen to know there in the source code the conversion of G10 takes place ?
[11:35:27] <Tom_itx> all your lead in's and lead outs would need adjustment too if they were too short
[11:35:32] <maximilian_h> i mean the conversion of the coordinates ?
[11:35:48] <Tom_itx> no
[11:36:16] <maximilian_h> I can live with the cutter paths since it is a water cutting machine
[11:36:37] <maximilian_h> and the diameter is compensated in the cam software
[11:36:42] <Tom_itx> oh only a 2d path then
[11:36:49] <maximilian_h> yes, only x and y
[11:36:53] <maximilian_h> G17
[11:37:00] <maximilian_h> nothing fancy at all

[11:46:33] <Tom_itx> i'm not sure if reversing the sign of all your x y moves would give you a mirror image or not. never tried it but just thought about it
[11:47:46] <Tom_itx> and if it's a waterjet, why not just flip one over after it's cut?
[11:49:06] <Tom_itx> we often would have to make a right and left hand part to fit both wings on a plane but since everything was 3d, flipping it over just wouldn't work
[11:57:42] -!- krusty_ar has quit [Ping timeout: 256 seconds]
[11:58:05] <maximilian_h> no, that does not work since the material is often coated or laminated on one side. In general often the material is not identical on both sides. And the cnc programs are big and use sub programs were the mirroring is switched on and off before the sub program.

[13:28:52] <JAS> :)
[13:29:46] <JAS> now i want to use 4th axis as spindle and i want to use my spindle as servo motor
[13:30:22] <JAS> so i am cant understand what all i need to start using servo as spindle
[13:30:29] <JAS> in 4th axis
[13:30:33] <JAS> need help

[15:49:36] <generic_nick> time for replacement?

[17:16:14] <GammaX> hmmm
[17:16:57] <GammaX> y u pick amd? Bleh!
[17:17:27] <L84Supper> been using mostly AMD since the 90's
[17:17:40] <GammaX> I was but then I went intel and havnt turned back..
[17:17:50] <Tuipveus> do you know some good hardware-shops for cables...
[17:17:55] <GammaX> started out with a amd athlon thunderbird 1.13 ghz...
[17:18:19] <Tuipveus> I have Atari Falcon 030 computer with scsi-2 (50 pin external) connector and harddisks with 68-pin internal connector
[17:18:39] <GammaX> wow lol
[17:18:49] <Tuipveus> this computer has been made in 1993, but I am not able to find adapter for that anymore
[17:22:03] <L84Supper> tried http://www.cablestogo.com and similar?
[17:22:46] <L84Supper> http://www.cablestogo.com/category/pc/pc-scsi/scsi-adapters
[17:23:06] <pcw_home> GammaX the AMD fusion MBs are known to work with current (Ubuntu 10.04 based) LinuxCNC
[17:23:08] <pcw_home> and some (like the Gigabyte and ASUS) are know to have good latency. Intel Mini ITX offerings
[17:23:09] <pcw_home> based on the latest Atoms all have video issues (at least there no decent driver support)
[17:26:45] <GammaX> pcw_home I just wanna stick with the cheapest thing. and since I already have a proc then All I need is a cheapo 20 dollar MB

[17:28:02] <pcw_home> 775 MBs should be common as dirt
[17:28:24] <GammaX> 30 bucks with onboard video
[17:28:48] <L84Supper> with tired core voltage caps
[17:29:17] <zultron> Nice numbers.
[17:29:24] <pcw_home> Thats pretty amazing for PreEmptRT
[17:29:34] <zultron> amazing indeed.
[17:29:58] <L84Supper> he's still working on kernel configs
[17:30:02] <zultron> Gives me hope for packaging LinuxCNC for Fedora. :)
[17:30:48] <L84Supper> something with kinematics needs to get sorted out as well
[17:31:08] <pcw_home> maybe at some point enough brute horsepower and fast busses win
[17:31:09] <zultron> Maybe folks will have a viable distro package with a more-or-less supported RT kernel.

[17:35:32] <generic_nick> yay, you have 7i48's in stock.
[17:36:43] <generic_nick> oh that reminds me, i have a spare atom pc from the old mill i was going to build. what to do with it....
[17:36:54] <GammaX> I was thinkin of buying the 6i25 in anticipation for the hardinge conversion...
[17:37:09] <GammaX> generic_nick Ill take it :D

[17:37:30] <generic_nick> i was thinking htpc
[17:37:39] <generic_nick> what's the 6i25?
[17:38:16] <generic_nick> nm, found it
[17:39:21] <GammaX> yerah the combo is only 225 os so
[17:40:55] <Tuipveus> hmm... I will try to search
[17:41:17] <Tuipveus> ebay just gives me tons of cables with internal 50 connector, not external
[17:41:33] <generic_nick> i use a 5i20, 7i33, 7i37, and 7i42 in my hardinge
[17:41:52] <GammaX> damn! thats a whole mess ofmoney
[17:41:57] <GammaX> those cards a re alot ofmoney
[17:44:06] <generic_nick> it's all relative
[17:44:20] <generic_nick> it's still cheap for a cnc lathe with a toolchanger
[17:44:49] <GammaX> .... correct!
[17:44:58] <generic_nick> i may have $2500 into it. i think that's cheap for what it is.
[17:46:02] <Tuipveus> that is what I need, but 50 connector should be male, not female.... http://www.cablestogo.com/product/13192

[18:15:29] <L84Supper> andypugh: https://www.youtube.com/watch?NR=1&feature=endscreen&v=95B8PDlnajk did you start with a complete mini-lathe-mill or did you add the mill to a lathe?
[18:16:44] <andypugh> It was like that from the factory.
[18:16:59] <L84Supper> https://www.youtube.com/watch?v=ZhICrb0Tbn4 somebody was asking about its weight the other day
[18:16:59] <andypugh> FWIW, a lathe saddle amkes a rather poor milling table.
[18:17:06] <GammaX> you guys using a fixture for tapping on your mills?
[18:17:21] <Loetmichel> andypugh: not really the right tool for pcb drilling... maybe get a speed up gear?
[18:18:02] <andypugh> I don't do much PCB drilling any more, I mainly use SMT and have the boards made for me (as Seeed is so cheap)
[18:18:28] <andypugh> GammaX: I think most of us use rigid tapping, mainly to taunt Mach3 users.
[18:19:28] <Loetmichel> GammaX: i tap with an battery screwdriver. or with the hand tool holder and a bit of muscle when the tapping bit is bigger than 8mm
[18:20:00] <L84Supper> mach3 could rigid tap if they wanted to, they are just busy with some other stuff :)
[18:20:02] <andypugh> Ah, yes, I also often use the cordless drill :-)
[18:20:08] <Tom_itx> andypugh or anybody else: the comments i made earlier about making a mirror image for a 2d flat patern... would it work by changing the sign on the x and y axis movements?
[18:20:15] <GammaX> andypugh is it as affective as a holder/tool?
[18:20:38] <jdh> the clutch slipping on the cordless drill seems to help tapping also
[18:20:52] <andypugh> Tom_itx: reversing any one axis ought to work.
[18:21:03] <archivist> 3mm taps die in a cordless drill!
[18:21:03] <Tom_itx> i realize that wouldn't work for a 3d profile
[18:21:37] <andypugh> Tom_itx: It ought to work for 3D too.
[18:21:48] <Tom_itx> the editor that came with my cad cam will do stuff like that pretty easy
[18:22:05] <Tom_itx> someone was asking about mirror image G codes earlier this morning
[18:22:21] <GammaX> anyone recomend a tool touch off?
[18:22:43] <jdh> I thoguht he really wanted to swap x/y, not so much mirror?
[18:22:54] <Tom_itx> he wanted a mirror image
[18:23:10] <Tom_itx> and
[18:23:18] <andypugh> If he wants to rotate around Z (which is the same as an XY swap) then G10 R90 is the way to do it.
[18:23:20] <L84Supper> how come only 10-32 taps break in aluminum? :) no other size breaks half way into the last hole in a project
[18:23:48] <Tom_itx> on a water jet i suggested just making two parts and flipping one over but he came back with the fact that the material isn't the same on both sides
[18:23:49] <andypugh> L84Supper: Just glue a bolt head over that hole.
[18:24:11] <Tom_itx> andypugh, it's on a waterjet
[18:24:23] <frallzor> GammaX expensive machine?
[18:24:30] <andypugh> Tom_itx: So? G10 R90 stilll works.
[18:24:34] <Tom_itx> ok
[18:24:41] <Tom_itx> i've never messed with that
[18:24:46] <GammaX> frallzor pm45cnc
[18:25:06] <frallzor> dont know that =)
[18:25:13] <GammaX> rf45 clone of some type
[18:26:15] <frallzor> http://www.cnc-plus.de/product_info.php?language=en&gm_boosted_product=-1467&products_id=1467& got one of those for my MechMate
[18:26:35] <frallzor> works pretty ok, just as long as you got the tools to measure when it triggers
[18:26:40] <GammaX> one thing I should have asked yesterday... how do I hook this bad boy up since my drives only take 4 wires... http://www.automationtechnologiesinc.com/wp-content/uploads/downloads/2012/12/KL342120-42-8A-KEY.pdf ? THanks!
[18:27:09] <GammaX> frallzor that looks real nice!
[18:27:38] <frallzor> i got the bit thicker one though, but same stuffs, just smaller size
[18:27:54] <andypugh> Tom_itx: he probably needs: http://code.google.com/p/grecode/
[18:28:43] <Tom_itx> we had a Fadal that used G50.1 and G51.1 for mirror image
[18:28:43] <jdh> <maximilian_h> so I cannot apply grecode to the whole program :(
[18:28:52] <jdh> that's when I left
[18:28:58] <Tom_itx> but the cutter paths would cut backwards
[18:29:14] <L84Supper> GammaX: they show you the 3 choices on the drawing
[18:29:44] <Tom_itx> and i didn't see a similar code for lcnc
[18:29:47] <Tom_itx> as the fadal
[18:29:49] <GammaX> L84Supper yeah i dont know which one to use lol
[18:31:35] <GammaX> L84Supper taking a 2nd look im assuming bipolar series...
[18:32:02] <GammaX> blue and red together would go to a+ yellow green goes to a-
[18:32:16] <L84Supper> where is a good tutorial on Bipolar series/parallel vs unipolar on steppers?
[18:33:47] <GammaX> http://probotix.com/stepper_motors/unipolar_bipolar/
[18:33:56] <Tom_itx> http://homepage.cs.uiowa.edu/~jones/step/index.html
[18:35:22] <Tom_itx> i'm pretty sure i wired mine parallel bipolar
[18:35:30] <Tom_itx> on those hybrid motors
[18:36:04] <GammaX> based on the torque-speed pic im lookin at parallel bipolar would be best...
[18:36:37] <GammaX> although amps will go up by 1.4
[18:36:50] <GammaX> X 1.4
[18:37:05] <Tom_itx> i can afford a couple amps
[18:37:18] <GammaX> I prolly shoulda gotten a diff PS
[18:37:20] -!- Nick001 has quit [Ping timeout: 252 seconds]
[18:37:36] <Tom_itx> if your supply won't hack it, wire them differently
[18:37:54] <L84Supper> that connection has the lowest inductance so it's faster but draws more current
[18:37:56] <Tom_itx> i tried to make sure mine would
[18:38:07] <GammaX> wait it should actually
[18:38:21] <GammaX> it says 6 amps per phase in bipolar parallel..
[18:40:59] <GammaX> if its 6amps per phase... does that mean my one 34 would be pulling 12 amps?

[18:43:30] <Tom_itx> mine are 4.2/phase in bipolar parallel

[21:00:49] <frallzor> although I cant tell since the picture is dark
[21:01:14] <frallzor> works good if you have a easy driven machine
[21:01:15] <frallzor> so no
[21:01:26] <frallzor> but never a good idea
[21:01:35] <frallzor> better use 2 drivers connected to same axis
