[00:34:02] <Skullworks_PGAB> * Skullworks_PGAB slaps skunkworks with a big red brick
[00:50:23] <Rugludallur> Skullworks_PGAB: out of trouts ?
[00:50:50] <Skullworks_PGAB> naw - bricks just hit harder
[00:51:00] <Skullworks_PGAB> trout I can eat
[00:51:40] <Rugludallur> Skullworks_PGAB: if you can cause the trout to swing sideways as you slap someone with it you should be able to hit someone harder with a trout :D
[00:52:13] <Skullworks_PGAB> I was just hoping to follow up on some info he sent me earlier
[00:52:55] <Skullworks_PGAB> that soulds like it might take practice...
[01:18:51] <skunkworks> I'm around..
[01:19:53] <Skullworks_PGAB> did you completely give up on the pluto now that you have a mesa?
[01:20:50] <skunkworks> no - I will probably use the pluto for testing
[01:20:59] <skunkworks> then maybe it will be used for a lathe
[01:21:15] <Skullworks_PGAB> also how does the pwm-pwm work vrs pwm/dir?
[01:21:40] <Skullworks_PGAB> pwm/dir I understand
[01:26:50] <skunkworks> 2 pwm signals are output - one for cw and one for ccw. instad of 1 pwm and one direction pin. same final result
[01:28:43] <Skullworks_PGAB> OK - I get that
[01:30:04] <Skullworks_PGAB> things could get messy if the borad received pwm on both at he same time I guess.
[01:30:48] <Skullworks_PGAB> this is almost the same as the UHU power stage.
[01:37:19] <skunkworks> not really. if both are in effect on - or off - the motor goes into breaking. (both upper or lower mosfets off)
[01:39:30] <Skullworks_PGAB> cool
[01:40:34] <Skullworks_PGAB> did you ever write down what the inputs/outputs were for the pads?
[01:41:34] <Skullworks_PGAB> * Skullworks_PGAB feels like he is holding pages 2 and 3 of 5.
[02:07:13] <skunkworks> no :)
[02:08:02] <Skullworks_PGAB> I have eagle - I have never USED eagle...
[02:10:12] <Skullworks_PGAB> I can see the diagram, and placement. but defining layers for post processing is out of my league at the moment.
[02:11:03] <Skullworks_PGAB> I need to dig up so good tutorials for eagle if such exist
[02:12:07] <skunkworks> eagle site has a few.
[02:12:15] <skunkworks> It take a bit to get used to - it is 'odd'
[02:12:17] <Skullworks_PGAB> raw G-code would be simpler - I can import and repost that very quickly.
[02:12:38] <Skullworks_PGAB> like blender?
[02:15:38] <Skullworks_PGAB> I'm going in circles now it seems - can't finalize the ballscrew design without knowing which motors I'm going to use.
[02:16:27] <Skullworks_PGAB> can't finalize motors until I have servo amp and power supply locked in
[02:16:40] <skunkworks> 98.5% of the time I just wing it
[02:17:00] <Skullworks_PGAB> * Skullworks_PGAB is not afraid of majic smoke...
[02:18:50] <Skullworks_PGAB> but I am getting to the point of ditching the whole servo idea and just using steppers.
[02:19:51] <Skullworks_PGAB> use a FAST EAS 2 axis bipolar for x/y and a gecko 203 for z and drive them via a USC
[02:23:36] <Skullworks_PGAB> use the ABBA ballscrews and kit from CNCFusion
[02:39:46] <lewing> Skullworks_PGAB: instructables has some reasonable eagle tutorials, google has a few more
[02:40:37] <Skullworks_PGAB> good
[02:41:53] <Skullworks_PGAB> I'm going to upload a sample vid of the same base machine that another user mounted Nema 23 servos direct drive.
[03:01:43] <Skullworks_PGAB> http://www.skullworks.net/include/X3_Servo_Mill.mov
[03:02:26] <Skullworks_PGAB> I had hopes of getting somewhere close to this...
[03:02:33] <Skullworks_PGAB> same iron
[03:02:50] <Jymmm> is that real time motion?
[03:03:01] <Skullworks_PGAB> yep
[03:03:41] <Jymmm> cool, the 2nd half sounds like grinding
[03:04:00] <Skullworks_PGAB> can do 400 IPM - but he has the vel limit turned down - it scares him too much running parts
[03:04:49] <Skullworks_PGAB> the grinding is the cheap single nook ball nut on each screw
[03:05:23] <Skullworks_PGAB> those rolled screws are crap for milling
[03:06:14] <Skullworks_PGAB> the rockford precision are much better but still make some grinding noise in the ball return tubes
[03:07:41] <Skullworks_PGAB> if he used double nuts you would not hear as much - and I think he did add them after finding he had .003" backlash.
[03:08:29] <Skullworks_PGAB> but that is the size of the iron - a grizzly labeled SEIG X3
[03:09:21] <Skullworks_PGAB> the ABBA screws with 4 circuit ball nuts are sweet - but pricey
[03:09:46] <Skullworks_PGAB> zero backlash as preloaded from factory.
[03:10:31] <Skullworks_PGAB> US made ballscrews have this huge gap.
[03:11:23] <eric_u> are they sending production to China?
[03:11:48] <Skullworks_PGAB> both Nook and Rockford make "T"ransport grade screws, and rockford has a precision grade rolled screw...
[03:12:20] <Skullworks_PGAB> but there is nothing avail between that and the high end ground screws
[03:12:37] <Skullworks_PGAB> nothing US made
[03:13:36] <Skullworks_PGAB> Hiwin and ABBA have an ultra precision rolled stainless screw and much better ball nuts.
[03:14:03] <Skullworks_PGAB> Tiawain made
[03:14:29] <Jymmm> ihave abba rails on my machine
[03:14:44] <Skullworks_PGAB> Hiwin also sells the ground screws for not too much more.
[03:16:23] <Skullworks_PGAB> ultra precision =.0005"/ft error
[03:17:01] <Skullworks_PGAB> I only have 16" x
[03:18:54] <Skullworks_PGAB> No - not to china - just a huge gap in the product lines
[03:21:07] <Skullworks_PGAB> Rockford only makes rolled screws. The basic transport grade has an error of .005" /ft - but the specs on pitch dia are the real killer
[03:23:03] <Skullworks_PGAB> it is possible to get a nut at MaxMC and a screw at MinMC that leaves you with .025" slop!
[03:23:41] <Skullworks_PGAB> and technically both are in spec
[03:27:59] <Skullworks_PGAB> http://www.skullworks.net/include/magnum_opus.mid
[03:28:16] <Skullworks_PGAB> I forgot I had that stashed there...
[03:29:39] <Skullworks_PGAB> bbl - need to go buy airline tickets
[05:26:35] <asdfqwega> Huh...I wonder if anyone has ever played with something like this: http://www.ar.com.au/~softmark/page44.html
[05:45:59] <Jymmm> how much?
[05:59:24] <asdfqwega> http://cgi.ebay.com/USB-Stepper-Motor-Controller_W0QQitemZ290105323641QQihZ019QQcategoryZ1502QQrdZ1QQcmdZViewItem
[06:08:45] <Jymmm> might be interesting to play around with. But they keep mentioning OCX
[06:09:13] <asdfqwega> Eh...that's because the software is windows only
[06:09:37] <asdfqwega> I think it's probably a standard usb-serial converter interface...
[06:10:09] <asdfqwega> you could experiment by throwing bytes through /dev/ttyUSBx in linux
[06:11:44] <asdfqwega> Hey, Jymmm...you can probably appreciate the thrill of getting a new tool
[06:11:56] <Jymmm> asdfqwega what's that?
[06:12:29] <Jymmm> or should I say.... what ya get?
[06:12:54] <asdfqwega> Guess what's coming to my house on Monday? http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=260088163840
[06:14:07] <Jymmm> asdfqwega ah, very cool!!!
[06:14:57] <asdfqwega> Yeah, I figured it was about time, after trying to build my own
[06:15:22] <Jymmm> asdfqwega I think we've all been there on that one =)
[06:36:53] <toastydeath> aw that's so cute.
[06:48:50] <demorphic> hello
[06:49:31] <demorphic> where could i get permission to merge a part of the EMC documentation on wikipedia ?
[06:49:39] <demorphic> could anyone help ?
[06:50:14] <demorphic> the current EMC entry on wikipedia leads to a blank page ...
[06:50:25] <demorphic> who should I ask ??
[09:51:13] <Rugludallur> just a thought, since demoorphic was asking for permission, would it not be sensible to release all the content on the website/wiki under Creative Commons and put a banner on the page
[09:52:46] <Rugludallur> or rather a small logo (I hate banners)
[09:59:08] <anonimasu> hello
[09:59:49] <Rugludallur> hello
[10:04:46] <anonimasu> Skullworks_PGAB: why are you considering skipping ser`vos?
[10:18:57] <feoc> how much torque can you normally handle with steppers before needing servo's?
[10:19:25] <feoc> iv got a manual machine im thinking of converting once iv finished setting up my cnc machine with emc
[10:19:40] <Rugludallur> I don't think it's a question of how much torque, I would rather say it's a question of how much torque at what speed
[10:19:45] <feoc> wondering if i need teh expense of servo's
[10:20:02] <anonimasu> probably not.
[10:20:16] <anonimasu> depends on machine size table weight..
[10:20:20] <anonimasu> and foremost budget..
[10:20:23] <feoc> it probably doesnt need that much speed i guess
[10:21:08] <feoc> looking at getting a horizontal mill if it goes for the right price
[10:22:03] <feoc> looks like it has more space available for a 5 axis if i ever feel the urge
[10:31:06] <anonimasu> the main problem is probably spindle speed..
[10:31:26] <anonimasu> though that's the same on all homebrew machines :)
[10:32:42] <anonimasu> atleast imo
[10:33:11] <Rugludallur> there are a couple of nifty boards out there though that make it pretty easy
[10:33:16] <feoc> yah
[10:33:32] <feoc> the spindle i can deal with on an on/off basis for the most part
[10:33:40] <feoc> just set the speed manually
[10:34:17] <Rugludallur> http://www.campbelldesigns.com/Combo-board.php
[10:34:25] <Rugludallur> That's a breakout board with built in spindle speed control
[10:35:50] <feoc> cool
[10:36:17] <feoc> gonna have to sort out a spindle control for my lathe
[10:36:26] <feoc> huge 3 phase thing
[10:36:32] <feoc> looks like a motor from a train
[10:37:23] <Rugludallur> feoc: might not be possible to use the motor and get speed control, is it a variable speed motor as it is or do you just use gears ?
[10:38:27] <feoc> on the lathe its a variable speed motor
[10:38:32] <feoc> its already a CNC machine
[10:38:35] <Rugludallur> feoc: ahh ok :D
[10:38:45] <feoc> so ill have to buy a proper spindle drive i reckon
[10:39:05] <Rugludallur> feoc: you can probably pick up a VFD on ebay cheap
[10:39:13] <feoc> VFD ?
[10:39:23] <Rugludallur> feoc: Variable Frequency Drive
[10:39:29] <feoc> ah
[10:39:55] <Rugludallur> feoc: AC converted to DC, and then converted back to stepped AC with a variable frequency
[10:40:45] <feoc> ill have to have a look
[10:40:59] <feoc> im heading down the workshop now anyway
[10:41:17] <feoc> its got a spindle drive in it but i dont know if it works or not
[10:41:30] <feoc> prolly be easyer to sell all that with the siemens controls
[10:41:35] <feoc> and buy nice new stuff
[10:42:34] <anonimasu> oh, I meant the biggest problem is low rpm small cutters..
[10:42:42] <anonimasu> so you never utilize the speed if your machine
[10:43:19] <anonimasu> hm, I'
[10:43:32] <anonimasu> I'm starting some ui-ish thing soon I think..
[10:43:32] <anonimasu> work on one
[10:44:42] <feoc> cyas later
[10:48:39] <Rugludallur> later
[10:48:54] <anonimasu> :)
[10:49:05] <anonimasu> pyqt looks like a good option..
[10:49:23] <anonimasu> then I can use the designer.
[10:49:32] <anonimasu> and then I can also use the NML/HAL stuff
[10:51:46] <Rugludallur> anonimasu: ui-ish,, what you making ?
[10:52:02] <anonimasu> Rugludallur: something that looks like a real user interface.. on a commercial controller..
[10:52:28] <Rugludallur> anonimasu: ahh
[10:52:31] <anonimasu> Rugludallur: that can be operated by panelmount buttons..
[10:52:49] <Rugludallur> for coworkers or you going into business ?
[10:52:53] <anonimasu> no, for myself..
[10:53:01] <Rugludallur> anonimasu: ok :D
[10:53:09] <anonimasu> axis is nice and all but it requres too much mouse/kb movement to get stuff done..
[10:53:11] <anonimasu> :)
[10:53:31] <Rugludallur> anonimasu: if you are looking at something a bit faster and more to the point tkemc is that
[10:53:41] <anonimasu> I dont like tkemc..
[10:54:30] <anonimasu> Rugludallur: it should act like a real control(the ui) also..
[10:57:08] <Rugludallur> anonimasu: ok, I'm not sure I understand what that means :) If you are just talking about emulating an embedded system it's not something I would do
[10:58:10] <anonimasu> Rugludallur: why not?
[10:59:35] <Rugludallur> Because the reason embedded controllers are set up the way they are is because they are embedded systems which have very limited resources, we on the other hand have vast resources when it comes to UI/Interface
[11:00:34] <Rugludallur> I don't see emc as as something to replace an embedded controler by emulating it, I rather see it replacing embedded controllers by surpassing them, different can be better
[11:01:05] <Rugludallur> But there are things in Axis which could be better, I would just rather put the work in to make axis better :D
[11:01:08] <anonimasu> yes, but the user interface is not better..
[11:01:45] <anonimasu> Rugludallur: I think for the hobbyist axis is all nice and so..
[11:01:48] <anonimasu> but try it with a panel..
[11:03:45] <Rugludallur> anonimasu: I know there are issues, mostly usability and performance as far as I am concerned but I would rather try to improve axis
[11:04:17] <Rugludallur> anonimasu: have you voiced your concernes/issues ?
[11:04:23] <anonimasu> Rugludallur: did you look at the axis code?
[11:04:30] <Rugludallur> anonimasu: noep
[11:04:38] <Rugludallur> anonimasu: nope, I have not looked at it
[11:04:45] <anonimasu> well, then you need to take a look..
[11:05:16] <Rugludallur> anonimasu: untill about 2 weeks ago I used tkemc
[11:05:54] <Rugludallur> anonimasu: but I decided to build the new plasma panel for axis since most users will be using that
[11:06:17] <anonimasu> Rugludallur: well, pyvcp is not axis.. pyvcp is pyvcp..
[11:06:43] <Rugludallur> anonimasu: true, but I would rather develop it as an integral panel in axis than a standalone panel
[11:07:14] <anonimasu> Rugludallur: well, have a look at the code :)
[11:07:16] <Rugludallur> anonimasu: it's easy to run it in a seperate window for tkemc then
[11:07:19] <anonimasu> let's continue this when you are done..
[11:07:27] <Rugludallur> anonimasu: will do :)
[11:07:54] <anonimasu> Rugludallur: also, people with minimills dont mind having the computer next to the mill on the bench..
[11:08:01] <anonimasu> or using a mouse to do stuff..
[11:08:15] <anonimasu> though that may be a assumption on my part..
[11:11:01] <Rugludallur> anonimasu: on a happier note the new thc stuff is nearing completion
[11:27:40] <lerneaen_hydra> http://bash.org/?240849
[11:28:25] <Rugludallur> lerneaen_hydra: :)
[12:28:38] <feoc> hola
[12:41:10] <alex_joni> 'lo
[13:52:20] <Rugludallur> hmm looking at components scale and mult2, aren't they really just two different implementations of the same thing ?
[13:52:39] <SWPadnos> scale hasa parameter (fixed multiplier), mult2 has 2 pins (I think)
[13:52:54] <SWPadnos> also, scale has an offset, doesn't it?
[13:52:57] <Rugludallur> SWPadnos: in most recent doc scale has gain in
[13:53:04] <SWPadnos> then they are the same ;)
[13:53:19] <Rugludallur> SWPadnos: scale has offset in but in all other regards they are the same
[13:53:33] <SWPadnos> there's a general but slow move toward getting rid of parameters altogether. as that happens, we'll probably see more cases like this
[13:54:02] <Rugludallur> SWPadnos: yup, and there will be an overlap like in this case
[13:54:34] <Rugludallur> SWPadnos: scale with gain as a pin does not make a lot of sense, scale with gain as parameter does make more sense
[13:54:58] <SWPadnos> yep, as long as parameters exist at all
[13:55:03] <SWPadnos> gotta run. brunchtime :)
[13:55:26] <Rugludallur> l8r
[14:11:17] <alex_joni> Rugludallur: why do you say that?
[14:11:22] <alex_joni> scale with gain as a pin does not make a lot of
[14:11:23] <alex_joni> sense,
[14:16:53] <Rugludallur> alex_joni: My point before was that scale with a parameter is different from mult, scale with a gain pin does the same thing as mult, only difference is the offset which could just be merged into mult imho
[14:17:06] <alex_joni> right
[14:55:20] <robin_sz> meep?
[14:56:04] <robin_sz> so, in case you care, the weather in Geneve is beautiful, 24 degrees, clear blu sky, some snow on the alps ... perfect.
[14:57:03] <alex_joni> same here, less the alps and the snow
[14:57:32] <tomp> are you in Geneve? any free samples of Societe' Geneve Dial indicators?
[15:00:08] <anonimasu> :)
[15:43:40] <robin_sz> the major local exports are cheese, cuckoo clocks and jig borers
[15:55:34] <cradek> EMC2 believes that energetic imbalances impede the flow and expression of Life Force, which we define as your vital energy, your natural healing capacity.
[15:57:18] <alex_joni> huh?
[15:58:01] <alex_joni> haha.. funny
[15:58:33] <cradek> http://www.planetshoup.com/easy/knit/soxemc2.shtml
[15:59:06] <alex_joni> Energetic Matrix Church of Consciousness (EMC2 )
[15:59:23] <alex_joni> EMC2 thinks of the energetic matrix as the "true self" of the individual. In other words, we are beings of pure energy. The energetic matrix is the most fundamental expression of our true being. Energetic imbalances exist, not in the body or mind or emotions or other parts of us. They exist in our energetic matrix.
[15:59:42] <cradek> well my energetic matrix is hungry
[16:02:32] <alex_joni> hmm.. my energetic matrix agrees
[16:07:05] <Rugludallur> my energetic matrix draws it's power from the higgs zero point energy
[16:09:31] <alex_joni> I just use recycleble ZPMs
[16:10:11] <Skullworks_PGAB> I need my pure energy rectified...
[16:13:41] <alex_joni> * alex_joni takes his bike for a ride
[17:45:10] <Rugludallur> Since i now need init values for checkboxes and sliders in pyvcp I'm thinking about implementing a generic init value solution for all input components, any suggestions/comments ?
[17:46:12] <Rugludallur> It seems that <value> is ignored for all of them, Tomp thought that they don't :(
[18:02:17] <jmkasunich> cd ..
[18:05:12] <Rugludallur> sorry john, this is the root directory
[18:05:15] <jmkasunich> heh
[18:10:35] <alex_joni> heh
[18:12:42] <Rugludallur> huh
[18:12:56] <Rugludallur> alex_joni/jmkasunich: any thoughts ont hat pyvcp thing ?
[18:13:10] <jmkasunich> not really
[18:13:20] <jmkasunich> It certainly seems reasonable to have initial values
[18:13:28] <jmkasunich> I'd probably stick them in the xml
[18:15:36] <Rugludallur> jmkasunich: I am sticking it in the xml, using the tag "initval" for now
[18:15:51] <jmkasunich> sounds good to me
[18:28:03] <alex_joni> Rugludallur: that sounds ok
[19:00:35] <chr0n1c> i am having a problem with axis not zeroing when i hit the touch off button? do i not have an option set right?
[19:00:57] <chr0n1c> the numbers stay where they were beforehand
[19:01:03] <alex_joni> chr0n1c: can you describe the exact steps you are doing?
[19:01:22] <chr0n1c> well, i load axis.. turn on the machine
[19:01:30] <chr0n1c> home all 3 axis'
[19:01:45] <chr0n1c> then proceede to touch off all 3 axis'
[19:01:51] <chr0n1c> but... they don't touch off
[19:02:10] <chr0n1c> they stay at whatever number it is from the turn on pos?
[19:02:23] <alex_joni> chr0n1c: are you using any offsets?
[19:02:28] <chr0n1c> hmm
[19:02:42] <chr0n1c> possibly...
[19:02:43] <alex_joni> what emc2 version?
[19:02:52] <chr0n1c> emc2 axis 2.14 i think
[19:03:00] <chr0n1c> what is the gcode to clear offsets?
[19:03:05] <chr0n1c> let me try that
[19:03:18] <chr0n1c> i didn't see it in the g-code reference
[19:03:23] <Skullworks_PGAB> G10 L2
[19:03:23] <chr0n1c> unless i missed it
[19:03:34] <chr0n1c> ok, L=?
[19:04:02] <alex_joni> http://www.linuxcnc.org/handbook/RS274NGC_3/RS274NGC_33a.html#1002552
[19:04:11] <Skullworks_PGAB> L2 is a work offset with a P augment to define which one
[19:04:21] <chr0n1c> p value out of range with l2
[19:04:22] <alex_joni> G10 L2 P1 X0 Y0Z 0
[19:04:41] <Skullworks_PGAB> G10 L1 would be a tool offset - but is not supported in EMC2
[19:04:47] <alex_joni> To set the coordinate values for the origin of a coordinate system, program
[19:04:48] <alex_joni> G10 L2 P - X- Y- Z- A- B- C-, where the P number must evaluate to an integer in the range 1 to 9 (corresponding to G54 to G59.3) and all axis words are optional. The coordinates of the origin of the coordinate system specified by the P number are reset to the coordinate values given (in terms of the absolute coordinate system). Only those coordinates for which an axis word is included on the line will be reset.
[19:04:50] <chr0n1c> oh
[19:05:51] <awallin> hi all
[19:06:11] <Skullworks_PGAB> Axis runs in G54 so use P1

[19:06:55] <Skullworks_PGAB> alex beat me...
[19:07:32] <alex_joni> didn't mean to
[19:07:32] <alex_joni> :P
[19:07:41] <alex_joni> awallin: hi, long time no see
[19:07:56] <Skullworks_PGAB> Maybe someday the will add G10 L1 support - but no one has really needed it yet.
[19:08:24] <awallin> alex_joni: hi, yep been busy with work and with the servo electronics on weekends. no time for emc...
[19:08:38] <alex_joni> awallin: I know how that goes.. unfortunately
[19:09:29] <awallin> now that the elextronics is almost done I'll do some HAL testing + pyVCP next weekend. maybe even get the motors running!
[19:10:07] <chr0n1c> ok, when i close out axisand restart it... it should reset all the offsets?
[19:10:12] <chr0n1c> but it doesn't?
[19:10:38] <chr0n1c> only if i reset the whole computer?
[19:11:34] <Rugludallur> awallin: here is something that might cheer you up: http://imagebin.org/8213
[19:11:38] <jmkasunich> resetting the computer should never be needed
[19:11:52] <chr0n1c> what is going on is... i use a whole bunch of different programs to write the g-code and they all put junk at the top for offsets and stuff...
[19:11:55] <jmkasunich> if something (offset, whatever) is lasting between runs of EMC, it was probably stored to the .var file
[19:11:57] <alex_joni> chr0n1c: if you set some offset those won
[19:12:00] <chr0n1c> do i justneed to start editing it out?
[19:12:01] <alex_joni> chr0n1c: if you set some offset those won't be forgotten
[19:12:05] <alex_joni> no matter what you do
[19:12:09] <chr0n1c> down to straight xyz moves?
[19:12:12] <alex_joni> they get written into the var file on shutdown
[19:12:17] <alex_joni> and reloaded the next time
[19:12:35] <chr0n1c> oh...
[19:12:43] <chr0n1c> is there a way to clear all machine vars?
[19:12:46] <Rugludallur> awallin: btw me and tomp have done some work on pyvcp, mainly just enabling default values to be set at init
[19:12:54] <alex_joni> chr0n1c: yeah, replace the var file
[19:12:55] <chr0n1c> with a quick mdi code?
[19:13:07] <alex_joni> overwrite it with one from /etc/emc2/sample-configs/
[19:13:11] <Rugludallur> awallin: Have not commited anything yet though, want to see ?
[19:13:18] <Skullworks_PGAB> if your code calls any other work coordinate sys then you will be lost (g55-g54.3)
[19:13:19] <chr0n1c> ok... will try brb
[19:13:41] <alex_joni> chr0n1c: make sure your ini doesn't have a POSITION_FILE entry
[19:13:54] <chr0n1c> will check
[19:13:56] <alex_joni> that one saves the axis position on shutdown, and reloads it
[19:14:08] <alex_joni> that's usefull on small machines without home switches
[19:14:14] <awallin> Rugludallur: nice screenshot. I'm afraid I don't have much time to review your code even if you would send it. Probably best to just commit it and have the whole emc community review it
[19:15:11] <alex_joni> bbl
[19:15:34] <Rugludallur> awallin: ok, I will commit it tonight probably
[19:15:48] <Rugludallur> awallin: new plasma design is done complete with sim, plan to commit it later tonight to
[19:16:46] <Rugludallur> awallin: might even throw in a video or two of the cutting
[19:16:59] <chr0n1c> hmmm
[19:17:04] <chr0n1c> i may use that file...
[19:17:18] <chr0n1c> do i need to create the file or jsut add a link to it in the ini
[19:17:24] <chr0n1c> position.var
[19:21:27] <awallin> Rugludallur: videos are always nice. I practiced using a DV camera and google-video two weekends ago at the helsinki model expo. There are two clips on my blog www.anderswallin.net
[19:21:48] <Rugludallur> awallin: ill check it out
[19:21:57] <Rugludallur> awallin: nice pics :d
[19:22:18] <awallin> oh btw it's not cnc related if you were hoping for some milling/lathe videos :)
[19:22:43] <alex_joni> chr0n1c: just add a link in the ini
[19:22:44] <Rugludallur> awallin: you fly, drive or sail models ?
[19:22:54] <alex_joni> look at some of the sim configs, I think one of them has it
[19:23:20] <awallin> Rugludallur: I've had some cars many years ago but late it's been mostly the sailing boats
[19:25:33] <Rugludallur> awallin: those sailboats are brilliant
[19:27:35] <chr0n1c> there is some awesome cnc vids on youtube
[19:27:42] <chr0n1c> a couple emc machines
[19:27:52] <chr0n1c> i was hoping there would be more emc machine vids there
[19:28:02] <chr0n1c> ty alex
[19:28:09] <alex_joni> chr0n1c: there will be in time
[19:28:14] <chr0n1c> i think that did the trick for fixing my offsets
[19:28:17] <alex_joni> but we're always happy to add more
[19:28:29] <alex_joni> chr0n1c: so if you have any.. just send 'em over
[19:28:33] <chr0n1c> i will put some vids of my machine up there when i get it tweaked
[19:29:02] <chr0n1c> and i jsut put up a shop light over the bench so i will have good lighting for the vids and pics now
[19:29:24] <awallin> I tried to make a list of EMC videos some time ago: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Videos if you have links to more of them, please add them to that page.
[19:30:31] <alex_joni> awallin: here's a newer one thanks to LH http://www.linuxcnc.org/content/view/35/13/lang,en/
[19:31:03] <chr0n1c> a lot of those vids didn't play because i don't have some crazy codec for them (from the wiki)
[19:31:27] <feoc> hola
[19:31:41] <chr0n1c> yo
[19:31:46] <feoc> question for ya about motors if you can help
[19:31:56] <feoc> got a rather large spindle motor on my lathe
[19:32:08] <feoc> 46-380V
[19:32:10] <feoc> 89A
[19:32:21] <feoc> and it only has 2 wires that feed it
[19:32:28] <feoc> would that mean its a DC motor?
[19:32:35] <chr0n1c> N10 G20 G40 G80 G90
[19:32:35] <chr0n1c> N20 G92 X0 Y0 Z0
[19:32:46] <chr0n1c> that's the code that screwed up my offsets?
[19:32:54] <Skullworks_PGAB> G92
[19:32:55] <chr0n1c> i need to see what it does still
[19:33:02] <chr0n1c> i don't know off the top of my head
[19:33:09] <lerneaen_hydra> feoc: could be either dc or ac
[19:33:15] <chr0n1c> ok... so if i get g92 out it would be fine?
[19:33:21] <lerneaen_hydra> hmm, funny that a motor that size isn't 3-phase AC
[19:33:30] <feoc> lerneaen_hydra how would it reverse direction ?
[19:33:33] <Skullworks_PGAB> I'd try it without it
[19:33:42] <feoc> i was expecting it to be 3 phase
[19:33:45] <lerneaen_hydra> depends on if it's dc or ac
[19:34:00] <Skullworks_PGAB> It will also change the part height offset with that G92...
[19:34:00] <feoc> im not sure
[19:34:03] <feoc> how do i find out
[19:34:06] <chr0n1c> how does ac reverse?
[19:34:07] <chr0n1c> lol
[19:34:23] <chr0n1c> you can't reverse the polarity on it can you?
[19:34:23] <lerneaen_hydra> ac would vary, probably there's a capacitor that you can move internally that drives the second phase
[19:34:34] <lerneaen_hydra> if it's dc then just reverse the polarity
[19:34:43] <feoc> i see
[19:34:47] <lerneaen_hydra> it could be made for only going one dir. though if it's dc
[19:34:55] <lerneaen_hydra> it should say on the motor though
[19:35:00] <feoc> i thought you could only reverse an AC motor with 3 phase
[19:35:17] <chr0n1c> 46 - 380 volts sounds like ac
[19:35:24] <feoc> the plate doesnt seem to have any info on ac or dc
[19:35:35] <lerneaen_hydra> funky
[19:35:42] <ds3> universal motor maybe?
[19:35:43] <chr0n1c> they may be different windings inside a cover that you can hookup different for diff voltages
[19:36:08] <Skullworks_PGAB> "emc2 uses software counting on the paralel port to see how fast the spindle is turning." >>> spelling typo on parallel.
[19:36:12] <chr0n1c> inside the cover... should be a diagram if that is so
[19:36:17] <feoc> if i tryed running some current through it DC would that damage it if it wasnt ?
[19:36:38] <chr0n1c> good question...
[19:36:49] <awallin> feoc: no it won't be damaged
[19:36:55] <lerneaen_hydra> I doubt it, unless there's electronics in it I don't see what could kill it other than heat
[19:37:14] <awallin> try with a small DC voltage. smaller servos will turn nicely with only a 9V battery
[19:37:20] <feoc> ok cool
[19:37:27] <awallin> if it's an ac motor it won't turn at all
[19:37:28] <feoc> well its not small by any means
[19:37:38] <feoc> it looks like a train motor
[19:37:52] <awallin> if it's a DC motor you should see the brushes
[19:38:02] <awallin> theyre usually replacable
[19:38:04] <lerneaen_hydra> try a 12V dc car battery with a fuse at 10A or so
[19:38:07] <Skullworks_PGAB> a (v won't turn it if there are belts attached
[19:38:12] <Skullworks_PGAB> 9V
[19:38:21] <alex_joni> wow http://www.imac.unavarra.es/parallel/imagenes.php
[19:38:49] <feoc> there are belts attached
[19:39:27] <toastydeath> ejsy
[19:39:30] <toastydeath> *what's wrong with belts
[19:40:00] <awallin> feoc: to test the motor at no load, remove the belts. do you have a picture of the motor ? might help
[19:40:02] <toastydeath> oh
[19:40:05] <toastydeath> that was for something else
[19:40:09] <feoc> i do have a pic
[19:40:16] <feoc> but i gotta go get some food
[19:40:26] <feoc> ill get it off my phone later on if i can
[19:40:40] <feoc> cyas later
[19:40:41] <feoc> cheers
[19:41:06] <Skullworks_PGAB> belts put a load on a motor.. so you won't get far with a little 9V battery
[19:41:55] <awallin> alex_joni: nice link to the hexapod project. looks like serious cash has been spent on the rails/ballscrews/servos/servodrives etc. is this EMC'er anyone we know ?
[19:44:53] <Skullworks_PGAB> Alex or... : whoever handles the Linuxcnc page... - that typo on the threading page... its not that we linux nerds can't spell, its just we can be lazy typists.
[19:46:47] <alex_joni> Skullworks_PGAB: what typo?
[19:47:10] <Skullworks_PGAB> "emc2 uses software counting on the paralelport to see how fast the spindle is turning." >>> spelling typo onparallel.
[19:47:58] <alex_joni> thanks for catching that
[19:48:13] <alex_joni> fixed
[19:48:19] <Skullworks_PGAB> np
[19:49:33] <Skullworks_PGAB> I have those kind of issues all the time - using this $5.99 noname keyboard.
[19:55:57] <chr0n1c> i spilled some mt.dew in my keyboard... it really scres up typing
[19:55:57] <chr0n1c> :D
[19:56:24] <chr0n1c> has anyone ever heard of profiler06?
[19:56:35] <chr0n1c> it's a neat img to g-code program
[19:57:08] <chr0n1c> i used it years ago to do some really cool stuff in wood, but lost the program since i didn't have a cnc... but i just found it again
[19:57:29] <chr0n1c> woohoo
[19:57:48] <chr0n1c> i never did find the emc2 img to g-code script cradek was talking about?
[19:58:06] <[1]Martzis> [1]Martzis is now known as Martzis
[20:00:52] <chr0n1c> seems as though i have a 3 hour engraving program on my hands
[20:00:54] <chr0n1c> :(
[20:02:54] <Skullworks_PGAB> what spindle speed?
[20:03:42] <chr0n1c> ehh, my dremel.. but my motors and slides can only keep up with 10 ipm
[20:03:56] <chr0n1c> i really really wish i had a servo driver and some motors
[20:04:46] <chr0n1c> i am using tiny 5 volt steppers and a stepperworld sp3 driver card
[20:04:58] <chr0n1c> oh, and an atx power supply
[20:05:02] <chr0n1c> :(
[20:05:08] <Skullworks_PGAB> unipolar or bi?
[20:05:15] <chr0n1c> 6 wires?
[20:05:20] <chr0n1c> i'm new to all this
[20:05:27] <Skullworks_PGAB> bi
[20:05:29] <chr0n1c> i am amazed i even got it all working!
[20:05:31] <Skullworks_PGAB> er
[20:05:32] <chr0n1c> lol
[20:05:33] <Skullworks_PGAB> uni
[20:06:03] <chr0n1c> i have been drooling over the xylotech driver.. i could give my motors more juice with it maybe?
[20:06:18] <Skullworks_PGAB> can that board take 34V?
[20:07:10] <chr0n1c> it has tiny 1/4 wat resistors and stuff on it
[20:07:47] <Skullworks_PGAB> brb
[20:08:02] <chr0n1c> there isn't much documentation for this board
[20:08:31] <chr0n1c> and the guy who sells it stopped selling it and said he had no idea if it would even work with emc
[20:08:36] <chr0n1c> and that's all the help he had for me
[20:08:49] <chr0n1c> i mean it's not listed on thier site for sale anymore
[20:09:06] <chr0n1c> there is two voltage inputs on the board...
[20:09:32] <chr0n1c> but i have them y'ed off to the same pwer supply
[20:09:43] <chr0n1c> 5 volts*
[20:09:56] <Skullworks_PGAB> hmm
[20:10:12] <Skullworks_PGAB> I saw the sp2... and a fet 3
[20:10:20] <chr0n1c> that's how the wiring diagram they sent
[20:10:21] <chr0n1c> shows*
[20:10:33] <chr0n1c> i bought the sp3 about 4 years ago to play with
[20:10:41] <chr0n1c> then it sat in the closet till a few weeks ago
[20:14:24] <awallin> gnight
[20:16:06] <Skullworks_PGAB> did you hook up 4 wires from the PC supply - Red - blk - blk - Yel ?
[20:18:26] <chr0n1c> no... i am only using the 5 volt side
[20:18:31] <Skullworks_PGAB> Yellow to V+ - Red to the 5V blacks to the ground (4 screw posts)
[20:18:47] <chr0n1c> should i hook the 12 volt to the motor?
[20:19:08] <chr0n1c> the paperworks say to use the 5 volts... i didn't wanna kill the card with more volts
[20:19:21] <chr0n1c> cuz i don't wanna buy a new driver right now
[20:19:23] <chr0n1c> lol
[20:20:31] <Skullworks_PGAB> you can use the 12V (yel) but you would need to and load resistors.
[20:20:42] <Skullworks_PGAB> need to add
[20:20:58] <Skullworks_PGAB> but that would give you more speed
[20:21:26] <chr0n1c> hmm..
[20:21:28] <Skullworks_PGAB> voltage makes speed, Amps provide torque
[20:21:39] <chr0n1c> i don't have any resistors handy
[20:21:54] <chr0n1c> i could get away with around 7 or 8 volts maybe?
[20:22:20] <chr0n1c> i can get the speed, the tourque was the prob
[20:22:27] <Skullworks_PGAB> plus without good docs it would be hard to calc the proper value
[20:22:50] <chr0n1c> so if i use 12 volts and use resistors to get back to 5 i would have more amps for faster tourque?
[20:23:47] <chr0n1c> would they need to be ceramic resistors or plain old 1/4 watt?
[20:24:44] <Skullworks_PGAB> not exactly - but using the higher voltage allows the windings to saturate faster - so the torque does not fall off as quick at the higher speed
[20:25:11] <Skullworks_PGAB> steppers have max power while stopped
[20:25:34] <Skullworks_PGAB> as they go faster the torque drops off
[20:27:17] <Skullworks_PGAB> this is because the "on" time duration for each step gets shorter to the point that the winding does not reach full saturation
[20:27:36] <chr0n1c> i'm following ya here i think...
[20:28:16] <chr0n1c> so i won't get much better with these motors and driver most likely...
[20:28:27] <Skullworks_PGAB> yep
[20:28:54] <Skullworks_PGAB> ebay!
[20:29:21] <chr0n1c> i think my boss mentioned he had some old motors from a cnc they stripped out and scrapped
[20:29:35] <chr0n1c> but.. he said they couldn't find them in his barn lol
[20:30:18] <Skullworks_PGAB> how big was the CNC
[20:30:23] <chr0n1c> i think i am ready to get an old bridgeport and go big if i am going to have to buy new motors and all
[20:30:36] <chr0n1c> i dunno, he tells stories, but only parts of them
[20:31:32] <Skullworks_PGAB> I have one of these coming...http://www.industrialhobbies.com/
[20:31:37] <chr0n1c> N1387250 G01 X2.344 Y1.276 Z0.0085 <- is hat some code or what!
[20:31:54] <Jymmmmmmm> * Jymmmmmmm mind is a terrible thing to waste
[20:31:57] <Jymmmmmmm> Jymmmmmmm is now known as Jymmm
[20:31:58] <chr0n1c> for a 2"x3" engraving with a .125 v cutter
[20:32:06] <Skullworks_PGAB> http://www.industrialhobbies.com/
[20:32:37] <Skullworks_PGAB> not sure if/when I'll do a cnc retro on it
[20:32:57] <Skullworks_PGAB> I'm doing my Seig X3 now
[20:34:33] <Skullworks_PGAB> how big is your unit - I may have some spare motors, good for a TAIG or sherline or X1/X2
[20:34:34] <Jymmm> Eons ago, I figured out how to convert any base number to any other base in your head easily, damn if I cn remember how I didn't it.
[20:34:56] <alex_joni> haha
[20:34:57] <chr0n1c> ohiopctech.com/cnc
[20:35:10] <alex_joni> Jymmm: "how I didn't it."
[20:35:25] <Jymmm> alex_joni What, you don't speak typo?
[20:35:36] <alex_joni> sure I do.. but sometimes I even laugh typo
[20:35:47] <chr0n1c> i speak fluent tpyo (mostly dyslexia related)
[20:35:48] <Jymmm> alex_joni There ya go
[20:36:02] <alex_joni> Jymmm: just thought that was a fun typo
[20:36:12] <alex_joni> otherwise I would have mentioned it .. not
[20:36:14] <Jymmm> chr0n1c you dislexic or just drain bamage setting in?
[20:36:53] <Jymmm> alex_joni The sad thing is I even wrote it down too, couldn't tell ya if I still have it or not.
[20:36:59] <chr0n1c> i dunno.. it's got something to do with the famous flowering colas of the cannibis plant i think
[20:37:07] <Skullworks_PGAB> chronic : is there any stickers on the steppers to spec what amp rating the windings are?
[20:37:42] <Skullworks_PGAB> whois burning rope?
[20:37:45] <Jymmm> chr0n1c Ah, so I'll already know the answer to "Are you stoned or jsut stupid"
[20:37:46] <chr0n1c> 5 volt/1.8 degrees a step/1A
[20:37:52] <chr0n1c> lol
[20:37:58] <chr0n1c> i am by no means stupid
[20:38:00] <chr0n1c> ;)
[20:38:03] <alex_joni> heh
[20:38:13] <chr0n1c> i might make stupid decisions sometimes though...
[20:38:18] <chr0n1c> but don't we all
[20:38:32] <alex_joni> chr0n1c: it's called life
[20:38:33] <Skullworks_PGAB> 1A - is that the board rating - or off the motor?
[20:38:33] <Jymmm> ok, seriously stoned and on a munchie run
[20:38:46] <chr0n1c> on the motor tag
[20:38:58] <Skullworks_PGAB> them is dinky
[20:39:26] <chr0n1c> i haven't found ny amp rating that i can run through the card to the motors yet
[20:39:32] <chr0n1c> yeah dinky... ;)
[20:39:39] <chr0n1c> my mill is dinky too
[20:40:06] <Skullworks_PGAB> yeah, so I've seen
[20:40:42] <Skullworks_PGAB> but that is like a lite single stack Nema 23
[20:40:52] <chr0n1c> i am thinking of building a bigger mill and then using the parts from this mill to make a vinyl record cutter
[20:41:01] <chr0n1c> :D
[20:41:25] <Skullworks_PGAB> record cutter - as in using old records for artwork?
[20:41:28] <chr0n1c> yes.. when i bought the card and the motors i had no idea of the tourque i would need for these slides
[20:41:43] <chr0n1c> it could be artwork, or actually cutting records
[20:41:51] <chr0n1c> putting the audio in the grooves
[20:42:11] <chr0n1c> i figure i can re-use old vinyl records by sanding the old grooves off
[20:42:15] <chr0n1c> then re-cutting them
[20:42:43] <Skullworks_PGAB> I'm thinking that with a good chopper drive, maybe a bigger stepper on Z that little machine could really move..
[20:42:54] <chr0n1c> i would really only need two axis' one to move the head up and down and one to move across
[20:43:01] <Skullworks_PGAB> reuse?
[20:43:11] <chr0n1c> yeah reuse
[20:43:23] <Skullworks_PGAB> you going to repress - or make a "Recorder"
[20:43:26] <chr0n1c> or recycle
[20:43:32] <chr0n1c> make a recorder
[20:43:48] <Skullworks_PGAB> cool
[20:44:00] <chr0n1c> i got my dj buddy scrounging for old turntables made of sturdy wood to be the cutting platter/base for it all
[20:44:14] <Skullworks_PGAB> bah
[20:44:21] <Jymmm> no torque
[20:44:30] <Jymmm> just a rubberband
[20:44:38] <chr0n1c> ok... so i need a decent drive card less than $200 bux if possible...
[20:44:41] <Skullworks_PGAB> you want a geek unit thats built in a granet or marble base...
[20:44:49] <Skullworks_PGAB> HEAVY DUTY
[20:44:53] <chr0n1c> lol marble
[20:45:15] <Skullworks_PGAB> you able to do soldier assy?
[20:45:15] <chr0n1c> we'll see what he comes up with...
[20:45:27] <chr0n1c> solder?
[20:45:27] <chr0n1c> yes
[20:45:37] <Skullworks_PGAB> thru hole PCB assy
[20:45:41] <chr0n1c> yeah..
[20:45:47] <chr0n1c> i have done plenty of that
[20:46:00] <Skullworks_PGAB> http://www.hobbycnc.com/4aupc.php
[20:46:01] <chr0n1c> i don't have the tools here to do smd
[20:46:20] <Skullworks_PGAB> I have one of these - and it goes great
[20:46:28] <CIA-19> 03jmkasunich 07v2_1_branch * 10emc2/docs/src/hal/drivers.lyx: fix documentation mistake, AX5214H is an ISA card, not PCI
[20:46:31] <Jymmm> chr0n1c sure you do, just gonna tak eyou a LOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOOONG time =)
[20:46:36] <Skullworks_PGAB> unipolar chopper driver
[20:46:58] <Jymmm> chr0n1c and a lot of cussing/tequilia/asprin
[20:47:13] <chr0n1c> lol jymm
[20:47:20] <CIA-19> 03jmkasunich 07TRUNK * 10emc2/docs/src/hal/drivers.lyx: fix documentation mistake, AX5214H is an ISA card, not PCI
[20:47:34] <Skullworks_PGAB> smell the resin of that non RoHS solder flowing...
[20:47:46] <chr0n1c> that board looks awesome
[20:48:14] <chr0n1c> ha, i got a spool of solder here from school... tons of lead
[20:48:39] <chr0n1c> they gave us eacha spool at the beginning of the year.. and i always used the teachers spool and saved mine
[20:49:13] <chr0n1c> about 12 years ago
[20:49:20] <Skullworks_PGAB> feed it from a 24VDC un reg powersupply - about 34V
[20:49:29] <Skullworks_PGAB> and it will just scream
[20:49:41] <chr0n1c> same motors?
[20:49:44] <chr0n1c> that i have now?
[20:49:44] <Skullworks_PGAB> same
[20:49:48] <Skullworks_PGAB> same
[20:50:20] <chr0n1c> sweet i can do a rotary with it also
[20:50:40] <Skullworks_PGAB> see a chopper stuffs High voltage into the motor windings fast, then cuts off
[20:51:07] <Skullworks_PGAB> then hits it again as the power bleeds off
[20:51:30] <Skullworks_PGAB> this gives you much higher USABLE speeds
[20:52:05] <Skullworks_PGAB> and its self adjusting to the motor to a point
[20:52:22] <chr0n1c> intersting...
[20:52:49] <Skullworks_PGAB> want to try one?
[20:53:07] <chr0n1c> the board... i am considering it
[20:53:13] <chr0n1c> i know this sp3 is a toy
[20:53:20] <chr0n1c> i want a machine... not a toy...
[20:53:27] <Skullworks_PGAB> well - there all toys...
[20:53:31] <chr0n1c> lol
[20:53:36] <chr0n1c> true
[20:54:04] <chr0n1c> i wishi had done more research befor i bought the sp3
[20:54:13] <Skullworks_PGAB> My IH is a toy... until it starts to pay for its self
[20:54:15] <chr0n1c> but it was good for learing to this point
[20:55:52] <Skullworks_PGAB> the Xylotex would also work with your motors - even give you more torque - you just don't hook up the center winding taps of each motor
[20:56:11] <Skullworks_PGAB> use only 4 wires per motor
[20:56:25] <chr0n1c> yeah i was looking at that
[20:56:37] <chr0n1c> how does that effect the positioning and stuff?
[20:56:52] <chr0n1c> only using the 4 wires
[20:57:31] <chr0n1c> i mean does it change the steps?
[20:57:41] <Skullworks_PGAB> has noting to do with position
[20:57:53] <Skullworks_PGAB> nope
[20:58:25] <Skullworks_PGAB> simple example
[20:58:25] <chr0n1c> ... this g-code is taking like 20 mins to load into axis
[20:58:32] <chr0n1c> geesh
[20:58:36] <Skullworks_PGAB> unipolar is like a "W"
[20:58:51] <jmkasunich> chr0n1c: how big is the file?
[20:58:58] <jmkasunich> usually axis loads pretty quick
[20:59:01] <Skullworks_PGAB> the center wire goes to the midle point
[20:59:54] <chr0n1c> i'm doing an engraving in lexan of a drawing my buddy did... it's 2"x3" and it's 3d... so there is a ton of xyz moves... with a .030 v cutter
[21:00:21] <jmkasunich> "a ton of moves" does that mean the g-code file is 100K, 1M, 10M, 1G?
[21:00:41] <chr0n1c> 4,731 kb according to windoze
[21:01:09] <Skullworks_PGAB> what was that final N#
[21:01:15] <jmkasunich> probaly less then 500K lines then...
[21:01:39] <jmkasunich> I wonder if cradek is lurking about....
[21:01:42] <chr0n1c> 656,485 lines
[21:01:54] <jmkasunich> I think they optimized axis to read g-code pretty quickly
[21:02:03] <chr0n1c> it's quick...
[21:02:07] <chr0n1c> on smaller files
[21:02:12] <jmkasunich> for a file like that a couple minutes might be expected, but not 20...
[21:02:17] <chr0n1c> i am using an ancient box to run emc
[21:02:31] <Skullworks_PGAB> how much mem?
[21:02:46] <chr0n1c> p2 233... could that have something to do with my motors not being up to par?
[21:02:50] <chr0n1c> 333 mb ram
[21:03:36] <Skullworks_PGAB> no - you said you were getting the speed - but losing spets if I recall
[21:03:40] <alex_joni> that's a bit lowend for axis
[21:04:07] <chr0n1c> ok.. so it is just the motors/power supply/driver
[21:04:10] <Skullworks_PGAB> losing steps is drive/hardware not PC
[21:04:25] <chr0n1c> mainly power supply and driver
[21:04:30] <chr0n1c> check
[21:05:34] <Skullworks_PGAB> though that CPU would limit the max pulse stream you could gen - but the drive/pwr is your current problem.
[21:16:30] <Skullworks_PGAB> JMK - did you see that short vid I posted yesterday?
[21:16:39] <jmkasunich> what vid?
[21:20:36] <Skullworks_PGAB> http://www.skullworks.net/include/X3_Servo_mill.mov
[21:21:12] <jmkasunich> 404
[21:21:16] <Skullworks_PGAB> this is the same base machine
[21:21:19] <alex_joni> This is your custom 404 "Not found" Error page. This page is displayed whenever a file that a web browser requests is not found on your website.
[21:21:22] <alex_joni> If you would like to change this page, edit the file "404.html" in your "www" dir.
[21:21:37] <Skullworks_PGAB> hmm - let me check
[21:21:55] <alex_joni> You
[21:21:55] <alex_joni> Don't
[21:21:55] <alex_joni> Belong
[21:21:55] <alex_joni> HERE!
[21:21:55] <alex_joni> GO BACK!
[21:21:58] <alex_joni> :P
[21:22:04] <alex_joni> Skullworks_PGAB: nice message
[21:22:18] <Skullworks_PGAB> yes
[21:22:32] <Skullworks_PGAB> had guys at work try to go snooping
[21:23:06] <Skullworks_PGAB> ah
[21:23:26] <Skullworks_PGAB> the M of mill needs to be uppercase
[21:23:49] <Skullworks_PGAB> http://www.skullworks.net/include/X3_Servo _Mill.mov
[21:24:10] <Skullworks_PGAB> http://www.skullworks.net/include/X3_Servo _mill.mov
[21:24:30] <Skullworks_PGAB> is it cutting the end off on your clients?
[21:25:58] <alex_joni> you said it in lowercase earlier
[21:26:15] <alex_joni> and now with a space
[21:26:21] <alex_joni> http://www.skullworks.net/include/X3_Servo_Mill.mov
[21:26:29] <Skullworks_PGAB> file is X3_Servo_Mill.mov
[21:26:53] <Skullworks_PGAB> have an ftp window open
[21:26:57] <Skullworks_PGAB> its there
[21:27:17] <alex_joni> the link I pasted works
[21:27:36] <Skullworks_PGAB> OK
[21:27:44] <alex_joni> well.. it downloads at least
[21:27:48] <alex_joni> no codec here :/
[21:27:59] <chr0n1c> eh, so i bought the hobby cnc driver kit
[21:28:09] <chr0n1c> looks like i'll be inhaling lead smoke soon
[21:28:18] <alex_joni> yummy
[21:28:18] <Skullworks_PGAB> thats the unit I'm trying to convert
[21:28:21] <chr0n1c> doh! more drain bramage!
[21:28:47] <alex_joni> chr0n1c: not if you're saturated with weed
[21:28:49] <chr0n1c> ha
[21:28:59] <Skullworks_PGAB> lead is the least of my worries
[21:29:50] <chr0n1c> i just made myself a .090 thou ball nose engraving bit
[21:30:03] <chr0n1c> out of the back half of a drill bit
[21:30:11] <chr0n1c> woohoo
[21:30:15] <chr0n1c> it should work..
[21:31:36] <Skullworks_PGAB> Alex your on a Linux box now..?
[21:31:54] <alex_joni> Skullworks_PGAB: nope
[21:32:13] <Skullworks_PGAB> Have you tried VLC media player?
[21:32:15] <feoc> my lathes drill head drive lost its magic smoke :(
[21:32:23] <Skullworks_PGAB> has all codecs built in
[21:32:24] <chr0n1c> doh!
[21:32:28] <stustev> be aware - the farther away from the original cutting edge the metal gets softer
[21:32:43] <chr0n1c> yes... i an engravng lexan
[21:32:46] <chr0n1c> should be fine
[21:32:57] <chr0n1c> thanks for mentioning that though
[21:33:07] <feoc> hoping its just transit damage to a supressor cap
[21:33:07] <chr0n1c> would be good to know if i wasn't a machinist ;)
[21:33:10] <Skullworks_PGAB> dishsoap and water 50:50
[21:33:11] <feoc> coz its got a crack right down it
[21:33:19] <chr0n1c> i have real tools at work lol...
[21:33:28] <feoc> hopefully replace the cap and it work :(
[21:33:32] <chr0n1c> i am building my home shop out of junk
[21:33:33] <Skullworks_PGAB> lexan cutting fuild and easy cleanup
[21:33:42] <chr0n1c> hmm..
[21:33:48] <chr0n1c> i been using wd40
[21:33:53] <chr0n1c> it's all i had around
[21:34:01] <chr0n1c> i do have dishsoap thoughj
[21:34:04] <feoc> lol
[21:34:07] <chr0n1c> never thought of that
[21:34:12] <Skullworks_PGAB> works too - but more mess
[21:34:50] <Skullworks_PGAB> maybe dilute it more since your engraving
[21:35:29] <chr0n1c> yeah... would some tranny fluid work? i have some of that in the grage lol
[21:35:53] <chr0n1c> of course it would work.. but i'd be covered in red oil!
[21:36:00] <Skullworks_PGAB> some stuff will attach that lexan
[21:36:07] <chr0n1c> oh...
[21:36:18] <Skullworks_PGAB> like carb cleaner or break cleaner
[21:36:35] <chr0n1c> i always used tap-magic for engraving when i had a real milltronics mill :(
[21:36:51] <chr0n1c> that stuff is da bomb!
[21:36:56] <chr0n1c> for engraving
[21:37:26] <feoc> any one here ever made a gantry mill?
[21:37:40] <Skullworks_PGAB> * Skullworks_PGAB almost wishes he could find a Partner 1 in a junk pile somewhere
[21:38:16] <Skullworks_PGAB> kerosene works GREAT for AL or Brass
[21:38:26] <feoc> feel like building somthing stupidly large when iv gotten used to it on my hurco
[21:38:34] <chr0n1c> i am trying to talk my buddy into building a 4'x8' gantry mill
[21:38:41] <chr0n1c> he is awesome with wood
[21:38:50] <chr0n1c> and i'll do the electronics
[21:38:52] <stustev> I have just installed the joypad_hal. It works. When I push (and hold) the button to turn the flood coolant on the coolant turns on/off/on/off rapidly for as long as I hold the button down. When I push and release the button the coolant doesn't change state reliably. How would I incorporate a latch into the code to make the state change one and only one time per each button push. I have tried to figure this out. It seems as if I am close BUT
[21:39:02] <Skullworks_PGAB> Feoc - did you get the Hurco up?
[21:39:24] <feoc> not got it pid tuned yet
[21:39:41] <feoc> fucked about with some random figures enough and got it moving now
[21:39:58] <Skullworks_PGAB> great - its progress
[21:40:02] <chr0n1c> are you using the hurco drives and such or did you gut it?
[21:40:21] <feoc> ill sit down and pid tune it when iv wired in the computer properly coz im having to remote X in via my lappy and its too sluggish
[21:40:31] <feoc> i am using the hurco drives and motors
[21:40:42] <feoc> it came with a burny servomate drive
[21:40:46] <chr0n1c> that's awesome
[21:40:52] <alex_joni> stustev: maybe add a debounce to the button?
[21:41:02] <alex_joni> there is a component called debounce..
[21:41:56] <feoc> quite good to watch the mill move around doing the spiral and 3d chips demo codes
[21:44:03] <Skullworks_PGAB> s w e e t.
[21:44:05] <stustev> I haven't tried that. I will. I added two and2's and two not to the example in the wiki. All above the two and2's and one not in the example. The debounce is used to delay the signals?
[21:44:25] <chr0n1c> de-bounce
[21:44:44] <alex_joni> chr0n1c: don't always assume native speakers
[21:44:57] <chr0n1c> oh yeah
[21:45:03] <chr0n1c> i was about to explain
[21:45:10] <chr0n1c> i keep forgetting we are on the internet
[21:45:14] <alex_joni> stustev: the debounce component is meant to filter out unwanted toggles in a signal
[21:45:17] <chr0n1c> and it's the whole world
[21:45:37] <alex_joni> for example noise which can be incorporated into an digital signal
[21:45:43] <feoc> gnight all
[21:45:48] <chr0n1c> later feoc
[21:45:51] <alex_joni> night
[21:45:58] <Skullworks_PGAB> rest easy
[21:48:22] <stustev> Would the debounce be added between the push button and the signal? BTW I am from Wichita, Kansas. This is almost a foreign country for some people.
[21:48:40] <alex_joni> stustev: you should have it like this:
[21:49:05] <alex_joni> button<->signal<->debounce<->signal<->halui (or wherever it's connected)
[21:49:28] <stustev> Thanks. I will try it.
[21:49:44] <alex_joni> np
[21:58:41] <jmkasunich> Skullworks_PGAB: finally got around to looking at the vid... fast machine
[21:59:04] <jmkasunich> (for its size anyway)
[22:01:37] <Skullworks_PGAB> yeah - well I don't expect to get that kind of speed - he can run it at 400IPM
[22:02:16] <Skullworks_PGAB> those are Nema 23 410oz-in from Camtronics
[22:02:23] <Skullworks_PGAB> direct drive
[22:02:27] <jmkasunich> servos?
[22:02:34] <Skullworks_PGAB> yes
[22:02:51] <jmkasunich> thought so, but I already closed the window... too lazy to look again
[22:02:56] <jmkasunich> 410 is a lot for a servo
[22:02:58] <jmkasunich> is that the peak rating?
[22:03:10] <Skullworks_PGAB> I think so
[22:04:10] <Skullworks_PGAB> "MCG ID23-005 PMDC sevo motors 400 oz in peak NEMA23 Frame PMDC servo motor with encoder"
[22:05:38] <Skullworks_PGAB> he went cheap on the screws - is likely going to replace the screws because the "transport" grade has almost .005 slop
[22:15:56] <alex_joni> good night all
[22:16:08] <Skullworks_PGAB> nite
[22:16:14] <Skullworks_PGAB> midnight?
[22:16:14] <jmkasunich> night alex
[23:01:58] <asdfqwega> where would be a good place to put a wiki page on tuning emc2 to use a rotary table / A axis?
[23:13:14] <Rugludallur> the emc wiki :D
[23:13:29] <Rugludallur> http://wiki.linuxcnc.org
[23:13:38] <Rugludallur> you can upload files to
[23:14:44] <bytecolor> anyone playing with apt360 want to try a front end for it?
[23:15:06] <asdfqwega> * asdfqwega smacks Rugludallur with a frozen waffle
[23:15:28] <Rugludallur> yum
[23:15:56] <asdfqwega> I know about the emc wiki...just where to insert the page?
[23:16:12] <Rugludallur> what url ?
[23:16:21] <Rugludallur> or how to insert it ?
[23:17:48] <asdfqwega> no...where
[23:18:20] <asdfqwega> where would it be appropriate to attach it?
[23:18:32] <Rugludallur> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TuningRotaryTables
[23:19:12] <Rugludallur> and then link to it from pages on tuning is what I would do
[23:20:14] <asdfqwega> Thanks, Rugl
[23:20:19] <Rugludallur> no prob
[23:20:23] <asdfqwega> I was over-thinking it :)
