[00:26:56] <moop> why is theta always 0 and seems to never be used in genserkins.c?
[00:30:33] <Valen> 3 contact version
[00:31:03] <Valen> gonna make a post on cnczone about it
[00:49:41] <Jymmm> http://cgi.ebay.com/TALOS-2500W-CO2-SHEET-AND-TUBE-LASER-CUTTER-ENGRAVER-/250657900139?cmd=ViewItem&pt=LH_DefaultDomain_0&hash=item3a5c60066b
[00:50:36] <Jymmm> Think it'll run on 120VAC@15A circuit?
[01:08:40] <skunkworks> heh - our laser at work is 1kw
[01:10:44] <skunkworks> it is 3 phase
[01:19:37] <alex_chally> I want a laser :(
[01:21:48] <skunkworks> it is nice to have access to.
[03:39:34] <Jymmm> Think I could turn a pen blank with it??? http://sfbay.craigslist.org/sby/tls/1854262036.html
[03:42:03] <krushia_> krushia_ is now known as krushia
[05:48:33] <elmo40> a useless app... ;) http://iographica.com/
[05:57:52] <PCW_> PCW_ is now known as PCW
[06:28:39] <MrSunshine_> anyone has charts of milling feedrates, spindle speeds etc of different materials?
[06:29:02] <Jymmm> Machinery Handbook does
[06:29:12] <MrSunshine_> even wood etc? :)
[07:32:32] <L84Supper> http://cgi.ebay.com/Bridgeport-Knee-Mill-9-x-32-Table-/250656291803?cmd=ViewItem&pt=BI_Mills&hash=item3a5c477bdb
[07:32:47] <L84Supper> seems to be the going price
[07:36:12] <alex_chally> L84Supper, I would be worried by the lack of pictures of the ways
[07:36:53] <L84Supper> yeah, they aren't too far, I could ask for more pics or stop by for a look
[07:37:19] <alex_chally> also, I have a belt on my Jheadish thing
[07:37:24] <alex_chally> instead of varispeed
[07:37:48] <alex_chally> and changing belts annoys the piss outa me
[07:41:01] <L84Supper> when I'm not looking for these they are just about getting rid of them for scrap, when I need 1 or 2, I can't find a good one :)

[07:46:03] <L84Supper> trying to look midwest
[07:46:14] <alex_joni> * alex_joni is from europe ;)
[07:46:39] <archivist> I fancy the cinci :)
[07:46:51] <archivist> but there is a pond in the way
[07:48:49] <L84Supper> only a 4 hr drive for me
[07:49:11] <archivist> go fetch!
[07:50:40] <L84Supper> I might grab this while I'm there http://cgi.ebay.com/BROWN-SHARP-1236-HI-TECH-CNC-CREEPFEED-SURF-GRINDER-/330451903050?cmd=ViewItem&pt=LH_DefaultDomain_0&hash=item4cf077e24a
[07:51:50] <L84Supper> 60HP !
[07:59:41] <archivist> thats a lot of HP to put through a grinding wheel
[08:03:55] <L84Supper> heh I only have 200A 240V 3ph service in that shop
[09:27:47] <PCW_> PCW_ is now known as PCW
[09:35:51] <pjm> for UK peeps: http://www.theiet.org/local/uk/south/dorset-wilts/weynovreprap.cfm reprap talk
[10:16:06] <IchGuckLive> Hi all the URL witch hosts the documentations is ofline and for sale so no info for stepconf on wiki http://www.distinctperspectives.com/
[10:24:42] <izua_> izua_ is now known as izua
[10:30:33] <IchGuckLive> the main doco is availabal as ever on the main url
[10:30:51] <IchGuckLive> but wiki directs to the non available
[10:38:11] <moooop> mmmmm i am hungry
[10:39:02] <moooop> i feel like some pork based meat product for lunch
[10:43:21] <PCW_> PCW_ is now known as PCW
[10:47:25] <IchGuckLive> someone on the channel
[10:47:27] <IchGuckLive> ?
[10:47:38] <IchGuckLive> i upgradet to 2.4.2
[10:48:00] <bricofoy> hi
[10:48:16] <IchGuckLive> there is new sthing in the stepconf All End and All Home
[10:49:01] <IchGuckLive> witch to use when the Home switches are also all end and Emergency switch
[10:50:01] <IchGuckLive> there are 9 switches in one circuit on the system
[10:53:07] <bricofoy> EStop is on the same line than limits and homes ?
[10:53:17] <bricofoy> I think this is not possible
[10:54:45] <IchGuckLive> i agree if i say all Ref then i can not EStop
[10:54:59] <IchGuckLive> if i go for all end i can not home the mashine
[10:55:06] <bricofoy> emergency stop must be on a separate line, and cut off directly motor power. Just input of Estop on the computer in not enough in terms of safety; because computer can take some time to respond to the emergency stop input
[10:55:07] <bricofoy> yeah
[10:55:11] <bricofoy> this is normal
[10:55:41] <IchGuckLive> so i got to new wirer the system
[10:56:01] <bricofoy> you must separate estop and limits/homes
[10:56:16] <bricofoy> but maybe you can have all limits and all homes on the same input
[10:56:26] <bricofoy> but I'm not an expert for this
[11:00:09] <IchGuckLive> if the brain fails ! i made a brige between 2 ports and said E-stop but then its not workabal hit Ref E-stop BAD idee
[11:01:13] <bricofoy> yep
[11:02:11] <bricofoy> for using one input fot both limits and home, you may use the "home to limit" option and use your limit switch as home switch
[11:02:39] <bricofoy> and in step conf you use "all limits" for the input
[11:02:55] <bricofoy> where are U from ?
[11:04:53] <bricofoy> what I said is from what I understand on the stepconf doc, but keep in mind I'm really not sure of that ;)
[11:05:52] <IchGuckLive> Im from germany
[11:06:20] <IchGuckLive> mashine is running
[11:06:26] <bricofoy> ok, france for me.
[11:06:27] <IchGuckLive> so first step is maid
[11:06:28] <bricofoy> nice !
[11:06:39] <IchGuckLive> im near bitch
[11:06:52] <IchGuckLive> French boarder
[11:07:03] <IchGuckLive> 25deg outside bright sunshine
[11:07:08] <IchGuckLive> 35
[11:07:18] <bricofoy> yep, 41 here yesterday
[11:07:20] <IchGuckLive> 25 woudt be nice
[11:07:33] <bricofoy> I'm near Perpignan, in the south
[11:07:38] <IchGuckLive> spain tock the hard 45 yesterday
[11:07:49] <bricofoy> yep
[11:08:32] <bricofoy> good news ! you can play frozen bubble over internet while machining without getting problems :)
[11:08:37] <bricofoy> just tested this :)
[11:09:06] <IchGuckLive> B)
[11:09:17] <bricofoy> may be this will not please the boss :) but it has to be said :D
[11:09:49] <IchGuckLive> do you now how i can get the max Ampere for the Stepper there is no label
[11:10:01] <bricofoy> no idea
[11:10:02] <IchGuckLive> i messure 7,5Ohm per Phase
[11:10:15] <bricofoy> but there are some experts on steppers here
[11:10:49] <bricofoy> if you get no answers, ask it again this eveming or this night :)
[11:11:57] <bricofoy> because they are most from US, so ist the very morning for them now
[11:13:05] <IchGuckLive> agree
[11:14:54] <jthornton> IchGuckLive: http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Stepper_Formulas
[11:17:08] <IchGuckLive> thanks
[11:18:57] <IchGuckLive> the old driver board did only 0,8A and it was at max level
[11:19:14] <IchGuckLive> so i guess on the amound of holding fource it can take more
[11:19:28] <IchGuckLive> i will go up to 1,5A
[11:19:57] <IchGuckLive> the new L298 can make 3A
[11:20:09] <bricofoy> yeah, second glue pot is usable on my machine :) I added a steel ball from old bearing in the pipe to turn it to a one-way valve, and it work :) (I had a problem with the two glue pots filling themselves when just one is pressurised)
[11:21:32] <IchGuckLive> i drive3 now the Stepper with 120steps 1at microstep and 1mm Tread at 0,8A
[11:21:45] <IchGuckLive> goes well to 400mm/min
[11:29:07] <IchGuckLive> no significant change as i now on 1,2A
[11:40:15] <PCW_> PCW_ is now known as PCW
[14:02:43] <mrsun_> hmm.. image to gcode should be able to select transparent areas of an image
[14:02:51] <mrsun_> say i want all white NOT milled at all
[14:03:04] <mrsun_> then it will withdraw, rapid over that to the next part that is going to be miled
[14:03:06] <mrsun_> miled
[14:03:08] <mrsun_> milled!
[14:12:17] <elmo40> try the inkscape gcode tool http://kalyaev.com/2010/20100423/gcodetools.html
[14:12:21] <elmo40> works quite well
[14:16:32] <mrsun_> broken download links :/
[14:16:43] <elmo40> really?
[14:17:13] <elmo40> just opened for me
[14:19:02] <elmo40> want me to dcc you the file?
[14:19:33] <mrsun_> gcode_tools-develope.py is what is broken
[14:21:51] <elmo40> sure, I can send you the file that I use
[14:22:52] <mrsun_> ahh so it worked this time =)
[14:23:23] <mrsun_> but where the hell do they end up :P
[14:23:47] <elmo40> no clue
[14:24:27] <mrsun_> but i do not get a menu item under "extensions" ?
[14:24:36] <elmo40> umm...
[14:24:57] <mrsun_> copied it to /usr/share/inkscape/extensions
[14:28:26] <mrsun_> ** (inkscape:15465): CRITICAL **: Inkscape::Extension::Extension* Inkscape::Extension::build_from_reprdoc(Inkscape::XML::Document*, Inkscape::Extension::Implementation::Implementation*): assertion `doc != NULL' failed
[14:28:27] <mrsun_> oh :/
[14:29:51] <elmo40> works for me
[14:36:03] <mrsun_> dont think its doing what i want to do
[14:36:09] <mrsun_> i wanna do a stipple of an image in wood
[14:36:23] <mrsun_> like photovcarve does but that freakin software creates watermarks :P
[14:36:46] <elmo40> what software makes watermarks?
[14:36:54] <mrsun_> photovcarve
[14:37:00] <mrsun_> from vectronic or whatever
[14:37:02] <mrsun_> its a trial version
[14:37:10] <mrsun_> cant afford to buy it just for one picture atm :/
[14:37:37] <mrsun_> and stippler doesnt compile .. not even close :/
[14:38:02] <skunkworks> hmm this? http://emergent.unpy.net/01108611472
[14:38:39] <mrsun_> ye doesnt compile
[15:16:11] <skunkworks> This seems to have ok latency http://www.tigerdirect.com/applications/searchtools/item-details.asp?EdpNo=6498211&SRCCODE=WEBLET03ORDER&cm_mmc=Email-_-WebletMain-_-WEBLET03ORDER-_-Deals
[15:16:55] <skunkworks> with the livecd - it seems to peak around 18us - I would say similar to the atom board
[15:17:33] <skunkworks> probably get better results with a smp kernel
[15:17:54] <skunkworks> but for me - it will work great.
[15:20:40] <skunkworks> onboard video seems to run opengl great also
[15:21:42] <skunkworks> all you need is memory and a heatsink. :) (well and a power supply)
[15:25:36] <skunkworks> and it is asus.
[15:54:35] <ChanServ> [#emc] "This is the #emc channel - talk related to the Enhanced Machine Controller and general machining. Website: http://www.linuxcnc.org/, wiki at http://wiki.linuxcnc.org/"
[16:07:53] <Jymmm> Eeeeewwwwwwwwwww TigerDirect
[16:09:13] <Jymmm> 1MB L2 Cache - seems low
[16:11:41] <skunkworks> it is for machine control.
[16:12:13] <Jymmm> skunkworks: I understand, but L2 cache will help in the respect.
[16:12:14] <skunkworks> I needed 2 pci slots minimum.
[16:12:19] <Jymmm> ah
[16:12:42] <Jymmm> can you use a riser card?
[16:15:36] <skunkworks> not without re-designing the case.
[16:16:53] <Jymmm> skunkworks: YOU CAN DO IT! lol
[16:21:35] <skunkworks> http://imagebin.org/index.php?mode=image&id=106253
[16:32:42] <Jymmm> skunkworks: Why 2 slots?
[16:36:47] <skunkworks> 2 mesa cards.
[16:37:45] <skunkworks> The goal3 board in the K&T is acting flakey after a few storms went through.
[16:38:27] <skunkworks> I feel that the asus board is made better also. :) (just a feeling)
[16:38:29] <Jymmm> skunkworks: do you have a whole house conditioner?
[16:38:39] <Jymmm> ^power
[16:38:50] <skunkworks> heh - no. this is a shop with 3 phase service
[16:39:07] <Jymmm> ah
[16:39:50] <IchGuckLive> hi all
[16:43:35] <IchGuckLive> is there any chance to find out how many amps a stepper takes
[16:45:46] <Jymmm> Lookup the datasheet maybe?
[16:46:20] <IchGuckLive> there are no numbers on the stepper itself all 3 streppers on the CNC are clear nothing at all
[16:47:20] <IchGuckLive> 120steps 52x52mm the old amp did ax 800 im now on 1,2A
[16:47:47] <IchGuckLive> the old amp did max 800 mA im now on 1,2A
[16:48:03] <celeron55> turn the current up to the point that you can't keep your hand on the stepper, and maybe a bit more
[16:48:37] <celeron55> heat is the limiting factor, anyway
[16:49:00] <IchGuckLive> at what time
[16:49:39] <IchGuckLive> lets say i make it run 400mm/min all the time zigzaging
[16:50:03] <IchGuckLive> it shoudt work more then 1hr
[16:52:42] <IchGuckLive> Geckodrives are not on ebay or ?
[17:00:41] <Fox_M|afk> Fox_M|afk is now known as Fox_Muldr
[17:04:58] <ries> IchGuckLive: should they???
[17:05:44] <IchGuckLive> ries: i dont now if they shoudt but all people are taking about the nice G540 and i can find only China
[17:07:22] <Jymmm> IchGuckLive: If you find Geckos in China, RUN AWAY AS FAST AS YOU CAN!
[17:07:23] <ries> IchGuckLive: http://www.geckodrive.com/product.aspx?c=3&i=14469
[17:12:49] <IchGuckLive> thanks all
[17:12:54] <ries> IchGuckLive: somebody I know is testing this on his machine : http://robotdigg.en.busytrade.com/selling_leads/info/1646984/Stepper-Motor-Driver.html
[17:13:27] <ries> he seems to have good experience with it so far, and compared to teh Gecko's they are very cheap, 45 USD or something for the 4Amp versions
[17:13:57] <IchGuckLive> http://stores.ebay.de/easyshopping08_CNC-Accessory_W0QQ_fsubZ362354919QQ_sidZ894244629QQ_trksidZp4634Q2ec0Q2em322
[17:14:04] <IchGuckLive> this is nice with nema23
[17:15:08] <ries> IchGuckLive: Personally I would go for a simple BoB and seperate drivers
[17:15:15] <ries> if one breaks, it's much easer to replace
[17:15:17] <IchGuckLive> also availabal less shippping in england
[17:16:08] <IchGuckLive> i agree therfore i use L297/298 its 6euro for replacement
[17:16:10] <ries> that helps... I cannot find anything local..
[17:16:42] <IchGuckLive> im around RAmstein Germany
[17:16:50] <ries> IchGuckLive: that depends on teh sort of machine you are running...
[17:17:03] <ries> Ahh.. europe... you can find everything there...
[17:17:11] <IchGuckLive> ponly tine ones max 600x600mm
[17:17:37] <IchGuckLive> it is pricy here 400% and more
[17:18:36] <ries> IchGuckLive: I know... I used to life in holland....
[17:18:44] <IchGuckLive> http://www.mechapro.de/catalog/stepper-motor-power-stages-c22/?osCsid=om8ma22cvkfob6st9juv2n1n72
[17:19:16] <IchGuckLive> this is very good but its old technics and well overprised conpare to the cheep new China thing
[17:19:39] <IchGuckLive> ok mashine is milling works nice
[17:20:51] <IchGuckLive> its my 18th CNC this goes to shipscalemodel man -> Proxxon MF70
[17:21:45] <ries> IchGuckLive: if you want to save money, some Chinese driver can be good, at least what my friend says , he uses his machine everyday, and doesn't break
[17:21:57] <IchGuckLive> it had a SMC800 the good old HPGL plotter Dos card
[17:22:15] <ries> The gecko's do break, even the G203v series.. but you get repair for free, but postal you need to pay yourself
[17:22:46] <IchGuckLive> i got also 1 running 8hr a day no problem on 2.5A 4 Axis 24V 320Watt
[17:23:45] <ries> IchGuckLive: I have teh g203v's (5) but I run it just once a week :)
[17:23:49] <ries> :(
[17:24:13] <IchGuckLive> B)
[17:28:33] <IchGuckLive> milling finishd i will upload a photo
[17:29:40] <IchGuckLive> works perfect within 2hr from arifing of the mashine and the window labtop
[17:30:09] <IchGuckLive> to Full 3D linux Heekscad/CAM and EMC on Standart L297/298
[17:33:11] <IchGuckLive> http://www.pictureupload.de/index.php?uploaded=1&id=115288 first part on the proxxon
[17:33:29] <IchGuckLive> but you may like to see the mashine
[17:33:38] <IchGuckLive> i need a flashlide its dark here
[17:37:41] <IchGuckLive> there is the mashine http://www.pictureupload.de/originals/pictures/210710193715_IMG_0805.JPG

[18:47:28] <mrsun_> i need higher rpm or a dremel addon for my mill :/
[18:48:30] <alex_chally> mrsun_, http://www.cnccookbook.com/CCHighSpeedSpindleAddOn.htm
[18:48:48] <mrsun_> ye something like that =)
[18:48:53] <mrsun_> but i do not realy have time to create one
[18:49:03] <mrsun_> as my time is running out fast and i work all day tomorrow :/

[19:05:05] <skunkworks> latency is better when installed... staying just under 14us
[19:09:51] <tom3p> alex_joni, hello, did the alibre freebie have wiring (like cable routing/panel layout) ?
[19:59:11] <skunkworks> nope - still creeps up to 18us
[20:23:21] <Fox_M|afk> Fox_M|afk is now known as Fox_Muldr
[20:27:30] <alex_joni> tom3p: nope, not even the full version which I have
[20:36:45] <tom3p> alex_joni, thx, i've seen the new SolidWorks & wondered ( http://www.youtube.com/watch?v=z5A7QFHln2w )
[21:11:58] <alex_joni> that looks awesome
[21:40:07] <foxtrot_lab> hi
[21:56:10] <foxtrot_lab> if i have home/limit switches, does that mean i dont have to touch-off/calibrate?
[21:56:32] <foxtrot_lab> * foxtrot_lab got his cnc working again
[21:56:45] <foxtrot_lab> now im back to my same issues of slamming into the table
[23:25:16] <Jymmm> foxtrot_lab: They have helmets for that sorta thing.
