[09:20:29] <piasdom> g'mornin all
[09:21:42] <micges_work> hi
[09:33:06] <Mire> anybody home?
[09:33:20] <pjm> morning
[09:33:31] <archivist> this early in the morning!
[09:33:37] <Mire> hello
[09:33:47] <piasdom> not at home (work)
[09:33:57] <piasdom> real early
[09:34:10] <Mire> awake, tho... good enuf
[09:35:26] <piasdom> who said i was awake :)
[09:35:27] <Mire> anybody here savvy w hostmot2 config? or HAL in general?
[09:36:00] <piasdom> havn't touch hal yet...sorry
[09:38:42] <Mire> I've got a 5i20 board in and working... should be very simple to configure. I need a hint tho.
[09:41:21] <pjm> ah cool, i have just got a 7i43 board + IO that i need to integrate into my machine
[09:41:54] <Mire> wonderful. do you know how?
[09:42:32] <pjm> not yet! I'll probably sift through a few of the examples that are floating around
[09:43:47] <pjm> worth having a pick over http://www.anderswallin.net/tag/cnc/ - this cnc uses a 5i20
[09:45:11] <Mire> I'm looking to drive RC servos while I tinker. I know that's been done. I need a good explanation tho. I'm a blank slate.
[09:48:00] <Mire> Machine I mean to drive in the end is Hardinge HNC, just like cradek's. First I need to play...
[09:48:52] <Mire> oh shnap that was a good link! thx pjm!
[10:03:56] <Mire> hmmm, still no .hal files. I'm at the nosebleed portion of the learning curve, meaning it's presently a wall. I'm certainly keen to learn tho!
[10:12:29] <pjm> Mire have u looked at http://www.anderswallin.net/2008/04/emc2-test-run/ ?
[10:12:39] <jthornton> Mire: run EMC then from the sample configurations pick hostmot2 stepper or servo then 5i20 for a sample config
[10:13:52] <jthornton> you have to have a 5i20 installed for the config to run
[10:15:37] <MarkusBec_away> MarkusBec_away is now known as MarkusBec
[10:25:57] <Mire> aha there's a full set of config files w this example! bueno. funny they seem to be packed. guess that's why we use unix.
[10:30:08] <pjm> ah yes if u open then on windows with the 'wordpad' thing they should display correctly
[10:30:14] <pjm> else just vi them
[10:42:41] <Mire> fun w fenestration.
[10:43:43] <archivist> * archivist should get of with his fenestration website
[10:43:59] <archivist> his/customers
[10:54:53] <cnc_valen> mornin all
[10:55:13] <cnc_valen> looks like whoever said it was a current limit thing was right
[10:55:25] <cnc_valen> we had it kind of move once now lol
[10:55:37] <cnc_valen> but it was hunting a whole bunch
[10:55:46] <cnc_valen> now it doesnt want to move at all
[10:56:23] <cnc_valen> what exaclty does "max_output" do?
[11:17:09] <piasdom> in axis...why,under file..open, doesn't file type show my ngc files?....is it because i creat them in gedit and save them as ???.ngc?
[11:20:31] <archivist> no, I use gedit
[11:24:25] <jthornton> is the extension in caps?
[11:26:42] <piasdom> not mine...
[11:26:55] <piasdom> that must be it....thanks
[11:27:05] <piasdom> i'll try
[11:27:43] <cnc_valen> hmmm any idea why we would be getting ~0 outputs?
[11:28:12] <cnc_valen> it looks like the pwm is turning on for the shortest time possible per cycle
[11:28:47] <piasdom> that's it..but i never use caps
[11:28:54] <jthornton> piasdom: http://www.linuxcnc.org/docview/html//config_ini_config.html#sub:%5BFILTER%5D-Section
[11:29:25] <piasdom> jthornton; thanks
[11:29:30] <jthornton> np
[11:34:34] <piasdom> i see i don't have a filter section in my ini
[11:35:41] <jthornton> just add it
[11:36:16] <piasdom> k
[11:45:18] <piasdom> i added this but nothing happens...in both axis and mini ini .... >> http://pastebin.ca/1565359
[11:45:51] <jthornton> that only works in Axis
[11:46:46] <jthornton> you missed a comma
[11:46:52] <piasdom> ya..i see mini shows all anyway
[11:46:54] <piasdom> ok thanks
[11:47:12] <jthornton> just put this PROGRAM_EXTENSION = .NGC
[11:48:07] <piasdom> ok
[11:52:43] <piasdom> do i need to write NGC = something....like png and gif did?
[11:53:23] <archivist> I would just rename files to lowercase
[11:53:54] <piasdom> i never use caps
[11:54:37] <archivist> gedit never defaults to upper either
[11:54:37] <piasdom> but i'll do that...thanks
[11:55:00] <piasdom> i don't know why it's doing that
[11:56:13] <piasdom> i always have to "save as" ????.ngc...i have to add the extension
[11:59:48] <jthornton> the = bla will just show up as the description
[11:59:50] <archivist> did you forget to put.ngc
[12:00:07] <jthornton> I see Axis has all files now so you don't really need it anymore
[12:02:52] <piasdom> i put .ngc,.NGC
[12:03:00] <piasdom> what files?
[12:04:41] <jthornton> file/open/ then you can select files of type All Files
[12:04:45] <piasdom> my axis does all machinable (*.ngc) to open
[12:05:11] <jthornton> click on that box and select all files
[12:05:20] <piasdom> and nothing shows for the rs files
[12:05:30] <piasdom> i usually do thanks
[12:20:10] <jthornton> * jthornton goes off to work
[15:54:14] <Jymm> hola
[15:55:45] <skunkworks_> Good morning
[15:56:27] <Jymm> skunkworks_: how's the gord counter-balance working out?
[15:59:56] <skunkworks_> it is more of a backup plan
[16:00:22] <skunkworks_> I did take the plunge and get a hd tv finally
[16:00:23] <Jymm> Well, as long as you don't backup too much, else you'll have the makings of a pie
[16:00:56] <Jymm> for the garage?
[16:01:09] <skunkworks_> heh - no
[16:01:43] <Jymm> well, what ya get?
[16:03:00] <skunkworks_> toshiba - open box. 55zv650u
[16:03:51] <skunkworks_> we spurged
[16:04:38] <skunkworks_> spurged? that just sounds bad.
[16:05:02] <skunkworks_> splurged
[16:05:20] <Jymm> how much?
[16:05:48] <skunkworks_> 1300
[16:06:21] <Jymm> cool, you can connect a USB HDD to it and watch DIVX/MPEG1/2 videos
[16:06:25] <skunkworks_> our pressent for 'finishing' the garage
[16:06:27] <skunkworks_> yes
[16:06:32] <skunkworks_> I have not tried that yet.
[16:06:46] <skunkworks_> seems to have pretty good reviews and lots of bells and whistles
[16:06:54] <Jymm> Too bad I don't use any of those formats anymore.
[16:07:20] <Jymm> The LG is kinda cool too, has ehternet and can watch netflix directly.
[16:07:50] <Jymm> but they sucked in the PC sharing - can only do mp3 and jpg (bastards)
[16:08:23] <skunkworks_> sorry - what was that?
[16:08:30] <Jymm> The LG is kinda cool too, has ehternet and can watch netflix directly.
[16:08:33] <Jymm> but they sucked in the PC sharing - can only do mp3 and jpg (bastards)
[16:09:25] <skunkworks_> heh - I read about that. we were planning on getting around a 42" but this seemed like too good of a deal.
[16:09:43] <skunkworks_> ended up watching the golf game yesterday - and I don't even like golf.
[16:09:57] <Jymm> you sick puppy!
[16:11:10] <skunkworks_> seems to do pretty good as a monitor also. Runnig 1280X1024 at the moment.
[16:11:51] <Jymm> cool, I need at least 2048 anymore
[16:12:08] <Jymm> which is a full 2-page layout
[16:17:00] <skunkworks_> it will do 1920X1080 thru hdmi.. if the computer can output that..
[16:17:26] <Jymm> Only the newest PC's can
[16:18:10] <Jymm> I have way too much older gear around here. VGA and DVI
[16:18:27] <Jymm> and already have even friggen cables as it is =)
[16:19:05] <Jymm> Though, i FINALLY found a great way to store all my cables after all these years
[16:21:10] <skunkworks_> cardboard box?
[16:22:13] <Jymm> No, tha't swhat I've been using for a while, it REALLY SUCKS as you have to find the right box that has the cab;e you need; It's always on the bottom of the box; and then the ends get tangled up.
[16:22:34] <Jymm> Let me see if I can grab the (preliminary) pic...
[16:23:11] <Jymm> crap, need to grab the netbook....
[16:33:12] <Jymm> skunkworks_: http://imagebin.ca/view/lIkN_ke.html
[16:34:04] <Jymm> But, I'm going to change that to either the REAR or SIDES using 4" PVC pipe
[16:34:39] <Jymm> They way it is now, the cables will never fall off, even if the rake tipped over.
[16:35:13] <Jymm> the reclosable green cable-tie is looped thru the shelving
[16:36:32] <Jymm> I just dont like the cables being bent that much, the 4" pvc shuld work out pretty well, and if I put them on the rear, it won't obstruct the shelves
[16:51:24] <fenn> i second the use of modular wire shelving
[16:51:28] <fenn> with wheels
[16:52:00] <Jymm> I found the PERECT containers for it too... fits four across perfectly.
[16:52:12] <Jymm> at home depot
[16:52:26] <Jymm> with shelves at 9" spacing
[16:52:36] <Jymm> and room on the bottom for bigger containers.
[16:53:05] <fenn> if it doesn't fit in a standard tub I don't want it :P
[16:53:30] <skunkworks_> neat
[16:53:31] <Jymm> I've already emptied like 4 cardbaord boxes and a bunch of misc stuff
[16:53:49] <Jymm> fenn: what's a "standard tub"?
[16:54:56] <fenn> http://www.ropakfish.com/fishing.php http://www.pkgprod.com/SeafoodPackaging/OurProducts/Default.aspx?ContentID=16
[16:55:20] <fenn> the 20lb fillet container
[16:56:01] <Jymm> I'm not storing fish tyvm =)
[16:56:07] <fenn> me neither
[17:00:22] <Jymm> Well, the containers I found are working out perfectly, they won't even slide out the sides. I just need to get some more bungy cords for the front
[17:03:13] <Jymm> skunkworks_: Since you haven't filled you garage yet, the racks are $100 at Costco, this is the 2nd one I've bought and works out great as you can adj the shelves in 1" increments might be somethng to consider for your garage as you can just roll them out of the way, or stack two deep if needed.
[17:04:00] <cradek> http://www.youtube.com/watch?v=DeJCzN90Aj4&NR=1
[17:04:02] <Jymm> skunkworks_: Having a 2lb deadblow hammer doesn't hurt either, but not required.
[17:05:26] <skunkworks_> Jymm: I have one of those..
[17:05:47] <skunkworks_> cradek: scary
[17:05:51] <Jymm> cradek: what is a RobbJack
[17:06:37] <Jymm> oh tooling
[17:21:31] <maximilian_h> does somebody know where I can find the code for arc interpolation ?
[17:22:20] <maximilian_h> I would like to read what happens when the arc from center to start and end differs, but is within the tolerances
[17:23:10] <fenn> probably in motion.c
[17:24:53] <maximilian_h> Hi fenn, did not see it there
[17:25:16] <maximilian_h> I was looking at the trajectory planner
[17:25:44] <maximilian_h> but there are lots of functions that do something i did could not the algorithm employed
[17:26:06] <maximilian_h> and it's the first time that I am looking at the trajectory planner, too
[17:30:51] <ZeroFLex> how many amps plasma cutters do people use for normal sheet metal ?
[17:31:35] <ZeroFLex> and what is the normal gap in mm between the sheet of metal and the torch ?
[22:19:30] <akafubu> ZeroFLex: did you ever find your answer?
[22:26:39] <ZeroFLex> yep
[22:26:48] <ZeroFLex> its a bit machine/torch dependable
[22:29:46] <ZeroFLex> i was just wondering
[22:29:55] <ZeroFLex> got a plasma cutter 45amp
[22:30:02] <ZeroFLex> just little cheap inverter one
[22:30:22] <ZeroFLex> but it doesnt cut that sweet (bit like a acytyleen torch)
[22:30:41] <ZeroFLex> think it hasnt got enought air of the compressor, need a bigger one
[22:38:49] <als_> what is the diff between hardinge AHC HNC is the AHC not NC controlled?
[22:40:31] <ZeroFLex> sorry dont know
[22:40:37] <ZeroFLex> ZeroFLex is now known as ZeroFlex_afk
[22:40:53] <ZeroFlex_afk> i must go to sleep :) its 00.40
[22:40:54] <ZeroFlex_afk> :(
[22:40:56] <ZeroFlex_afk> laterz
[22:42:30] <als_> cradek: you around
[22:47:05] <als_> I found this site thanks anyway http://www.machinemanuals.net/web_pages/hardinge_chnc.htm
[23:21:36] <MarkusBec> MarkusBec is now known as MarkusBec_away
[23:25:19] <elperepat> Hi!
[23:26:24] <fenn> why don't they just run those cables in a flexible conduit?
[23:26:34] <elperepat> I have a question concerning emc2, Stepconf wizard in particular. Anybody can help me?
[23:26:47] <fenn> not i, never used stepconf
[23:27:06] <elperepat> ok
[23:27:25] <fenn> however, you're more likely to get an answer if you ask the question you wanted to ask, instead of asking to ask
[23:28:46] <elperepat> sure... I was wondering if there was a way to specify backlash for each axis using stepconf or if I had to manually edit the configuration files. Stepconf advise doing so because it won't be able to re-edit them afterward.
[23:29:02] <elperepat> advise against...
[23:29:41] <fenn> O_o "hardinge enthusiast's group": http://www.machinemanuals.net/web_pages/hardinge_hlv.htm
[23:33:11] <fenn> one might infer that hardinge is also a type of cigar, but that doesn't seem to be the case
[23:52:16] <als_> fenn: the one with the cigar is that one automatic or manual?
