[00:37:08] <pcw_home> only easy choice if you have no APIC
[00:38:31] <Tom_itx> would it be asking for trouble if i did the 10.04 update on it?
[00:38:43] <Tom_itx> i had trouble getting 10.04 to work on it previously
[00:39:29] <Tom_itx> or can i just update linuxcnc to 2.5.2 or whatever the current release is and retain 8.04 ubuntu?
[00:42:36] <andypugh> Yes
[00:43:07] <Tom_itx> how would i go about it?

[00:44:05] <Tom_itx> i've got ^^ that old pc i've gotten 8.04 to work on and wanted to update
[00:44:10] <Tom_itx> 2.5.1 i think
[00:44:17] -!- thesisb has quit [Ping timeout: 252 seconds]
[00:44:20] <Tom_itx> yes
[00:44:48] <Tom_itx> it's gonna end up in the shop if it works
[00:45:52] <andypugh> In that case you can probably just upgrade through the update manager
[00:46:23] <Tom_itx> well i tried that but it says this version is no longer supported

[00:50:56] <andypugh> Who says that about what?
[00:51:12] <Tom_itx> the package manager said that
[00:51:29] <Tom_itx> i prodded a bit and it finally went to get a list
[00:51:44] <Tom_itx> i think linuxcnc was in there

[00:52:41] <Tom_itx> restarting so we'll see...
[00:54:02] <Tom_itx> 2.5.2 now

[01:09:26] <tjtr33> re: the supplied 'probe-hole.ngc' , it's a great O-word subroutine, but read it thru before using.
[01:09:36] <tjtr33> This isnt criticism, just be aware it is an example.
[01:09:48] <tjtr33> I annotated it here so I understood what it did ( might be wrong, check it yourself :) http://pastebin.com/YZ2CFW5v
[01:09:53] <tjtr33> be aware that its imperial, and uses a 6mm dia probe, and returns bolt hole info, and uses some hard coded distances your machine might not be able to achieve

[01:40:03] <dgarr> i made some ngcgui-compatible probe subroutines from cradek's originals. Their defaults would be easy to modify. They can be used with ngcgui or any other way as a subroutine.

[02:20:33] <tjtr33> dgarr: nice adding the params to the probe. thx
[02:20:34] <tjtr33> is there a way to detect unit of measure? so a routine could tell if the caller was Metric or Imperial?
[02:20:57] <tjtr33> and if the current plane was G17/18/19 so the probe worked in that plane?
[02:27:47] <dgarr> in master, there is support for a named parameter for the plane: #<_plane>
[02:28:52] <dgarr> and for metric: #<_metric>
[02:31:08] <tjtr33> thx! had not found that. i had written plane dependant inside & outside probes on Heidenhain ( system vars held 'tool axis' rather than circular interp plane )
[02:31:30] <tjtr33> so you can probe on a tomb stone, all sides
[02:32:07] <tjtr33> very nice.. is there a doc describing these system vars?

[02:43:12] <tjtr33> opps thx again
[02:43:31] <chopper792> Hello all, I am working on a jog pendent and all axis move, but all have the same issue. The issue is no matter what mode the pendent is in (x1 x10 x100 ) the machine always moves at .100" per click. Any clues on what I should look for? Like I said all axis move its just all move .100" no matter the mode of pendent.
[02:45:58] <dgarr> most of the predefined named parameters are available in master only but #<_vmajor> and #<_vminor> are available in 2.5.x (i think)
[02:46:09] <cradek> chopper792: http://linuxcnc.org/docs/html/man/man9/motion.9.html
[02:46:22] <cradek> here is a listing of motion's input pins including axis.N.jog-scale
[02:46:42] <cradek> you are obviously not getting that set right, according to your knob
[02:47:15] <cradek> so you need to check whatever hal hookups are supposed to set that
[02:47:45] <chopper792> http://pastebin.com/J4dkGaZD
[02:49:20] <cradek> yep looks like that's the stuff to debug
[02:49:38] <tjtr33> does mux4.0.sel0 & 1 respond correctly?
[02:49:41] <cradek> you should perhaps check scale1, scale2, pend-scale, etc with halmeter
[02:51:15] -!- abetusk_ [abetusk_!~abetusk@cpe-24-58-232-122.twcny.res.rr.com] has joined #linuxcnc
[02:51:55] <abetusk_> What do you guys think about attaching a USB microscope to a CNC to measure position for backlash and wear?
[02:52:24] <chopper792> Pendent count works fine in halmeter, but scale is stuck on 0.1" and scale 1 and scale 2 stay false. So it appears I have my pins wrong for scale 1 and 2 I would think
[02:52:36] abetusk_ is now known as abetusk
[02:53:14] <cradek> yep I bet you're onto it
[02:53:54] <Tom_itx> pendants are awesome
[02:53:55] <cradek> since you're successfully reading other parport.1 pins your port is working, it seems like it might just be a pinout (or wiring) problem
[02:54:35] <cradek> abetusk: a dial indicator might be simpler, cheaper, and more precise
[02:55:16] <abetusk> cradek, are there digital dial indicators that can work over the full range of motion (say half a foot or so)?
[02:56:08] <chopper792> Sounds like it. That is what I was figuring but needed to bounce it off someone else
[02:56:17] <chopper792> Thanks I will let you know if I got it working
[02:57:13] <tjtr33> thats more stroke than 'dial indicator' has. but linear scales and lvdt s allow that much. are you trying to check long distances?
[02:57:23] <chopper792> quick question.... Scale 1 is = to ? (.1, .01, .001) or nothing like that?
[02:57:46] <abetusk> tjtr33, I'm trying to get a more precise estimate of backlash and wear across the leadscrew

[02:59:22] <L84Supper2> what are the dates for the meet-up in Wichita? 13-19th?
[02:59:36] <Tom_itx> 17-23 iirc
[02:59:47] <L84Supper2> ok, thanks
[02:59:51] <tjtr33> abetusk long distances are often checked with a stack of gauge block against a hard stop. touch off on hard stop, move some distance, feel the gauge in between
[02:59:54] <Tom_itx> i got the link here...
[03:00:08] <tjtr33> for some meaning of 'long'

[03:00:52] <Tom_itx> it's in one of those replies
[03:00:53] <cradek> yeah glass scales are used for this
[03:01:01] -!- Keknom has quit [Quit: Leaving.]
[03:01:02] <cradek> it's not clear to me what you'd "point" your webcam at
[03:01:24] <tjtr33> edge of a joe block stack?
[03:01:33] <abetusk> cradek, a reference pattern
[03:01:37] <cradek> not to mention how you'd interpret the picture by machine
[03:01:38] <tjtr33> edge of a cadillac gauge?
[03:01:38] <Tom_itx> From Monday the 17th to Sunday the 23rd
[03:01:46] <cradek> seems like a very wrong technology
[03:02:20] <cradek> a glass scale has a very precise reference pattern and an optical reading device that reads it perfectly into a machine-understandable form
[03:02:50] <L84Supper2> thanks the GFW seems to be blocking/breaking that site
[03:02:52] <cradek> to do that instead with webcams and laser printers or whatever is silly
[03:03:28] <Tom_itx> i'm local so if you need info ask
[03:04:14] <L84Supper2> just incredibly slow
[03:04:29] <tjtr33> maybe an old-school vernier? (tho a magnifying lens is all that Hauser jig-bores put over it, not a camera )
[03:04:48] <cradek> do you want to read it with the machine or by eye?
[03:05:03] <Tom_itx> L84Supper where you comin from?
[03:05:23] <tjtr33> yes cradek, ^^ important point i was missing

[03:06:32] <Tom_itx> fun
[03:06:52] <L84Supper2> far more formal that expected :)
[03:06:57] <Tom_itx> the link finally opened?
[03:07:00] <L84Supper2> that/than
[03:07:23] <L84Supper2> yeah, http://thread.gmane.org/gmane.linux.distributions.emc.user/42692/focus=42699 has the dates
[03:08:23] <L84Supper2> first trip I didn't pack a suit, and all the functions are formal
[03:08:33] <Tom_itx> heh that would suck
[03:09:20] <tjtr33> check out beijing tailors, 24hr turnaround ( check That qc :)
[03:09:42] <Tom_itx> tell em all your bags got lost
[03:09:46] <L84Supper2> yeah, there's a mall in the hotel as well

[03:23:56] -!- Tecan [Tecan!~fasdf@unaffiliated/unit41] has joined #linuxcnc
[03:24:08] <chopper792> cradek: How does the scale get its input for 3 different modes with only 2 pin connections? example would be the pendent is wired for pin 10 = x1 pin11 = x10 pin12 = x100 the common for all them is to pin 14. Is the default always .1 (x100) unless one of the other two (x1, x10) are active?
[03:25:17] <chopper792> I ask this since in hal config under watch I select all input pins and no pins change state when I select x1,x10,0r x100
[03:25:56] <chopper792> almost like the selection knob is not working even though I tested it to make sure that selection knob worked.
[03:29:25] <tjtr33> the 2 wires of the knob are the 'select' lines of the mux. they combine to a binary code 00 01 10 11 that select 1 of up to 4 values for the scale.
[03:31:36] <tjtr33> man mux2 may help
[03:31:42] <chopper792> there are 4 wire for the knob total. x1 x10 x100 and common. Should I be using the x1 and x10 or the x10 and x100
[03:31:51] <chopper792> I am reading mux now
[03:32:37] <tjtr33> sorry i thought your hal paste showed a mux
[03:33:42] -!- hjhart has quit [Client Quit]
[03:34:11] <chopper792> it does
[03:34:41] <tjtr33> try man mux4
[03:35:17] <chopper792> with only 2 pin inputs though, so I am trying to understand how 3 selection options with 3 different wires can have only 2 inputs from the pendent.
[03:35:32] <tjtr33> nononono the mux4 selects 1 of 4 outputs using 2 bits input
[03:35:43] <tjtr33> not what you want
[03:36:19] <chopper792> correct
[03:36:59] <tjtr33> you have 3 inputs and want no 'muxing' just use 3 inputs ( 3 pins ) and select the appropo scale when only 1 is true
[03:38:50] <Tom_itx> chopper791 is the logic the level you think it is?
[03:38:54] <Tom_itx> or reversed
[03:39:01] <chopper792> by my logic that is what it should be doing.
[03:39:19] <Tom_itx> one is default and the other 2 switch
[03:39:23] <Tom_itx> that gives you 3
[03:39:35] <chopper792> I did not see the reason for any mux if I had the ability to send it 3 different inputs for my scale factor
[03:40:20] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/configs/sherline/my_jog.hal
[03:40:22] <Tom_itx> there's mine
[03:40:27] <chopper792> ok so .1" is default then as its working that way now and the other two should be the pins for .01" and .001" or x1 or x10
[03:40:51] <Tom_itx> ignore the 'fast' value, it was too fast for my mill so i fudged
[03:41:55] <Tom_itx> mine is input to a mesa card though
[03:42:14] <chopper792> yeah mine is simple...parallel port...lol
[03:42:25] <Tom_itx> the idea is the same
[03:42:47] <chopper792> I have tried all my available input pins and nothing works for my mux inputs.
[03:43:06] <chopper792> no matter the pin it always moves .1"
[03:43:22] <Tom_itx> use a simple switch on the input and make it work with that first
[03:43:26] <tjtr33> you have 3 inputs, they goto hal code that selects a single scale value based on which input is true, that value is connected to axis.N.jog-scale
[03:44:08] <tjtr33> a mux wont do that
[03:44:10] <Tom_itx> 2 inputs and a defalut value
[03:44:16] <chopper792> I have not tried separates yet, by my simple mind that is how it should work.
[03:47:48] <chopper792> let me drink this beer and mess around a bit more
[03:48:02] <chopper792> be back soon and hopefully with a working pendent
[03:48:14] <Tom_itx> i'll read about it tomorrow

[03:48:50] <gammax-Laptop1> Im comtemplating which probe to buy...
[03:50:26] -!- thesisb has quit [Client Quit]
[03:50:53] <gammax-Laptop1> i would like one that can probe very accuratly and also be used as a touch off
[03:51:03] <gammax-Laptop1> but also last a long time. any thoughts?
[03:52:27] <Tom_itx> renishaw is the defacto standard
[03:52:44] <gammax-Laptop1> but is also not an ASS LOAD of money lol
[03:52:45] <Tom_itx> they are simple devices inside
[03:52:53] <Tom_itx> get one off ebay
[03:53:08] <gammax-Laptop1> i cant find a cheap one at all
[03:54:52] <tjtr33> try voltage drop technique: insulate the probe tip, insulate the workpiece , use a pullup resistor to the tip, connect wkpc to gnd, monitor when the tip goes low, use carbide tip
[03:55:08] <tjtr33> cheap, but requires insulation
[03:55:14] <tjtr33> very accurate
[03:56:18] <tjtr33> and keep it clean, air blast & alchohol clean the surfaces
[03:56:38] <Tom_itx> no room for error
[03:57:05] <gammax-Laptop1> yeah im not a fan of that style tjtr33 I thought about it... just rather have an actual probe...

[08:39:41] <GammaX> 3/8 x 16mm or 5/8...
[08:40:01] <GammaX> Tom_itx, idk where your seeing this! lol
[08:40:22] <archivist> all sorts here https://sdp-si.com/eStore/CoverPg/Couplings.htm
[08:40:49] <archivist> each type has its application
[08:40:58] <Tom_itx> sdp has hundreds
[08:42:32] <GammaX> archivist, well i need some with a little bit of flex but that cna hold on very strong and be a little flexible with movement im thinkin of oldham style ones now
[08:42:37] <archivist> your mounting alignment quality also defines which type you need

[14:24:56] <Vq> sure
[14:25:15] <PetefromTn> what do you generally use it for?
[14:25:28] <Vq> http://cgcookie.com/blender/cgc-series/blender-basics-introduction-beginners
[14:26:28] <Vq> Dabble with raytracing and creating visualisations.
[14:27:46] <PetefromTn> Thanks for the link dude! Looks like a nice simple intro that I need. Was gonna download a simple .stl viewer but then searched a bit and found blender which seems to do so much more.
[14:28:25] <PetefromTn> Not sure if it is best thing for my purposes tho. Not really into 3d computer animation just want an avenue to be able to draw and view 3d files for cad cam work.
[14:28:39] <tjtr33> Vq would you suggest using the blendercam version (2.67)? same basic interface, more cnc oriented http://blendercam.blogspot.com/p/download-and-installation.html
[14:29:06] <PetefromTn> Thats what I downloaded...
[14:29:20] <PetefromTn> at least I think so. Stable release 2.67
[14:29:47] <PetefromTn> How would you setup blender to be more CNC oriented as far as the toolbars etc.
[14:29:53] <Vq> tjtr33: I have actually never used blendercam.
[14:30:21] <PetefromTn> There's a blendercam?
[14:30:33] <PetefromTn> Did not know that..

[22:48:55] <GammaX-Shop> its an omron EE-SY672
[22:52:01] <Tom_itx> do you run base thread or servo thread?

[23:13:27] <Tom_itx> does that look reasonable for a parport encoder input?
[23:13:40] <Tom_itx> i don't have a way to test it
[23:13:44] <Tom_itx> for Gamax
[23:14:15] <Tom_itx> do you use base thread or servo thread for parport stuff?
[23:14:30] <andypugh> base-thread
[23:14:44] <Tom_itx> my mesa stuff uses servo thread
[23:15:23] <Tom_itx> i'm not sure about the gain on scale either
[23:15:34] <Tom_itx> would that reflect his encoder count per rev?
[23:15:36] <andypugh> no need to setp the index-enable
[23:15:39] -!- Tecan has quit [Ping timeout: 252 seconds]
[23:15:52] <andypugh> The encoder scale needs to be set correctly
[23:16:03] <Tom_itx> i'm not sure what his is
[23:17:08] <Tom_itx> not sure what parameter that is andy

[23:18:13] <Tom_itx> encoder.<chan>.position-scale
[23:18:46] <andypugh> Needs to match the number of counts per rev.
[23:18:51] <Tom_itx> yes
[23:18:55] <andypugh> Or you can lie and get rpm directly :-)
[23:19:03] <Tom_itx> it's a bit different on mine since i'm using the mesa function
[23:19:43] -!- ve7it has quit [Remote host closed the connection]
[23:20:12] <Tom_itx> if you're using it in single input mode you don't need to define the others do you?
[23:20:42] <Tom_itx> encoder.0.phase-A etc
[23:22:33] <Tom_itx> he left anyway
