[00:03:29] <A0Sheds> most inkjet cartridges don't actually run out of ink..... they count drops then start to drop nozzles (grey scaling) then just stop printing
[00:03:58] <FinboySlick> Yeah, I know.
[00:04:21] <A0Sheds> it takes the re-fillers and chip makers a year or so to catch up
[00:04:55] <A0Sheds> thats why HP and Lexmark are in the ~120's now for cartridge numbers
[00:05:02] <FinboySlick> I remember running a couple leads to a 'spent' toner cartridge and monitoring it with an amp meter to fake a fuse blow.
[00:05:24] <FinboySlick> And suddently, the printer knew it had a 'new' cartridge and printed just fine.
[00:05:42] <A0Sheds> Samsung still has fuses in their toner cartridges
[00:06:22] <A0Sheds> it's areal honest business
[00:07:34] <FinboySlick> I wonder what would happen if a company decided to just go honest and just plain lay out the bullshit and make it their main selling point? We're not going to kill parts of your printer just so you buy new ones.
[00:07:52] <A0Sheds> the industrial marking inkjets use serial codes to ID cartridges and then they also add RFID so that you can't swap cartridges between vendors
[00:09:07] <A0Sheds> well the HP patent on the original thermal printhead expires real soon
[00:09:47] <FinboySlick> I guess if we lived a lot longer, current patents wouldn't be so bad.
[00:10:02] <FinboySlick> We'd actually get to reap the advantages of innovation.
[00:10:12] <A0Sheds> FinboySlick, too many patents, they pretty much stick together, the only hope might be China
[00:11:58] <FinboySlick> A0Sheds: Yeah. I'm sort of against patents myself, sofrware or hardware. Definitely the biotech ones.
[00:12:42] <FinboySlick> Perhaps patents could last 3 years or so, and if that's not enough of a lead for you to grab the market, you don't deserve it.
[00:13:44] <A0Sheds> the other problem is the courts
[00:14:30] <A0Sheds> if a small outfit gets sued by a large co, how do they come up with 2-3 million to fight?
[00:15:00] <FinboySlick> A0Sheds: Yeah, that too.
[00:15:42] <FinboySlick> Same the other way around too. If megacorp steals your patented tech, it'll be expired before you even see the end of the trial.
[00:15:46] <A0Sheds> there was a kickstarter project for a 3d DLP printer
[00:15:59] <A0Sheds> they raised $500K
[00:16:27] <FinboySlick> And had to spend 3M on lawyers?
[00:16:49] <A0Sheds> now I'm watching for the lawsuits from 3d systems
[00:17:17] <A0Sheds> they even had a product manager in #lemoncurry
[00:17:36] <FinboySlick> 3d systems did?
[00:17:39] <A0Sheds> yeah
[00:17:58] <A0Sheds> kind of passive agressive
[00:18:15] <FinboySlick> I think it's sad.
[00:18:31] <_abc_> Umm yesterday this url was posted here
http://www.rockler.com/product.cfm?page=21387&site=ROCKLER
[00:18:42] <_abc_> It's a good idea, but how does one affix the rail to the table?
[00:18:52] <_abc_> It is not at all obvious?
[00:19:31] <_abc_> It seems to come with special flat headed screws. Is that it?
[00:19:42] <A0Sheds> must be
[00:20:08] <A0Sheds> http://images.rockler.com/rockler/images/25736-06-500.jpg
[00:20:16] <FinboySlick> _abc_: double-sided sticky tape! ;)
[00:20:23] <A0Sheds> looks like they have holes every few inches
[00:20:26] <_abc_> oh noes
[00:20:35] <_abc_> Yes but I wonder how strong they are
[00:20:51] <_abc_> thin headed screw, thin T rail, large fulcrum, ooops
[00:20:57] <FinboySlick> _abc_: I guess that depends on how far appart the screws are.
[00:21:53] <A0Sheds> http://www.rockler.com/product.cfm?page=21334&site=ROCKLER
[00:21:55] <_abc_> I'm not in USA I wonder if I can press some C profile into such service for a very light duty engraver. Has anyone tried this?
[00:22:17] <_abc_> You know Al C profile normally used for trim or for curtain service.

[00:25:27] <A0Sheds> nevermind same data sheet
[00:26:18] <A0Sheds> I need to start a open hardware software USB racing wheel project
[00:26:52] <_abc_> what?
[00:26:57] <_abc_> what is a racing wheel?
[00:27:06] <_abc_> steering wheel?
[00:27:13] <FinboySlick> _abc_: that'd be my guess
[00:27:26] <A0Sheds> http://www.bhphotovideo.com/c/product/758788-REG/Thrustmaster_4169056_T500_RS_GT5_Racing.html
[00:27:57] <FinboySlick> A0Sheds: Ever played FlatOut (the first one)?
[00:27:57] <A0Sheds> using industrial servos vs toy motors
[00:28:32] <A0Sheds> heh, I'm not the gamer, I'm just tired of buying and replacing crappy wheels
[00:29:06] <FinboySlick> A0Sheds: LAN games are really really really cool.
[00:29:19] <FinboySlick> It's like Dukes of Hazard :)
[00:29:28] <FinboySlick> Redneck racing.

[00:31:13] <A0Sheds> the only tough parts seems to be the USB API for each game
[00:31:39] <FinboySlick> A0Sheds: You only need a hid driver and you'll be fine.
[00:31:48] <FinboySlick> A0Sheds: It's all standardized now.
[00:32:05] <A0Sheds> not for all the features
[00:32:22] <A0Sheds> I hear that the force feedback part is unique
[00:32:31] <A0Sheds> but I'll soon find out
[00:33:25] <A0Sheds> have to sniff the USB and see
[00:33:35] <A0Sheds> anyway, BBL
[00:34:34] <_abc_> Force feedback protocols have been cracked since the 90s
[00:34:35] <FinboySlick> The wheel to driver part likely is unique, but the driver to game bit is standard.
[00:34:41] <_abc_> Look and you shall find
[00:34:47] <A0Sheds> ah ok
[00:34:54] <_abc_> Also using servos as feedback is not so good
[00:35:02] <_abc_> You want a cogging free motor for that
[00:35:22] <_abc_> Neither steppers nor servos fit that picture
[00:35:46] <_abc_> Cheap wheels cheat by using a geared motor, the cogging 'disappears' in the crap mechanical linkages
[00:36:16] <A0Sheds> brushed DC motors with gears
[00:36:16] <_abc_> You could do something using a 2 phase AC motor and a rather fancy driver heh
[00:36:25] <A0Sheds> haven't seen anything better
[00:36:28] <_abc_> A0Sheds: yes that is what makes them suck
[00:36:51] <FinboySlick> A0Sheds: Pneumatic rack and pinion!
[00:36:59] <FinboySlick> Break your kid's arms with ease.
[00:37:01] <_abc_> 2 phase AC motor will not cog and allows adjusting feedback force without limit
[00:37:41] <A0Sheds> how much can a used ton of steering boxes cost?
[00:38:39] <A0Sheds> add you own steering wheel
[00:40:08] <FinboySlick> Force feedback is only part of the story though.

[03:27:08] <Loetmichel> mornin'
[03:28:00] <Loetmichel> hmmmm.... a source in germany for TB6560AHQ chips anyone? have to repair some driver boards...
[04:08:59] <mrsun> http://existenz.se/out.php?id=57784 =)
[04:11:11] <mrsun> wait
[04:11:20] <mrsun> wrong ... but that is cool also :P
[04:12:15] <mrsun> http://www.wimp.com/metricsystem/
[04:12:17] <mrsun> there it is :P
[04:14:34] <Loetmichel> hrhr... so the imperial system is good for exercising your brain calculator ;-)
[04:15:10] <mrsun> =)
[04:15:27] <archivist> you dont have to use fractions with inches!
[04:18:34] <Loetmichel> hmmm, when i see drill bits (or screws) with writings like "30/64" on them that tells me: you may not hAVE to, but lot of jou do ;-)
[04:26:35] <mrsun> http://www.wimp.com/underwaterdetonation/ so thaats how raincolouds are made? :P
[04:28:04] <jackc> Loetmichel: 30/64?
[04:28:13] <jackc> 15/32nds, please ;-)
[04:28:38] <jackc> drill sizes in general are annoying though, given the letter and number indexs
[04:28:57] <jackc> but you print out a handy little chart once with index name, fraction, and decimal, and youre all set
[04:28:58] <Loetmichel> may have been 31/64, didnt read it thadt well
[04:29:10] <jackc> ya, it woulda been then
[04:29:29] <jackc> theyre always damn hard to read on smaller bits, i think thats why the index letter and numbers were made
[04:29:38] <jackc> so even if you can only fit '9' on it, its still labelled
[04:30:20] <jackc> aight plane bording, have fun
[04:30:21] * jackc &
[04:30:56] <Loetmichel> mrsun: i have done my military service at a subhunter at the navvy...ive seen the drop bombs detoinate as near as 50-100 yards... its even more impressive live ;-)
[04:32:21] <anonimasu> anyone have the full country and area code for mesanet's fax number?
[04:32:25] <Loetmichel> s/drop bombs/depth charges
[04:32:57] <Loetmichel> anonimasu: ask pcw_home?
[04:33:07] <anonimasu> well he's home at the moment :)
[04:34:00] <anonimasu> pcw_home: if you read this what is the full country code and stuff for ordering from you and what was the name of the connectors and stuff I need for the 7i40-lv-rohs encoder inputs
[04:34:05] <alex_joni> anonimasu: it should be +1 510 ...
[04:34:22] <anonimasu> thanks!
[04:35:10] <anonimasu> if i get 80% of the rpm at 400v (460 is max) I'll have my motors spinning at 4000rpm
[04:35:33] <mrsun> Loetmichel, hehe, never been close to an explosion so i wouldnt know =9
[04:35:33] <anonimasu> like 8m/min for my mini mill..
[04:35:34] <mrsun> =)
[04:36:07] <anonimasu> like 3.6 seconds for the longest axis end to end.
[04:36:32] <anonimasu> and 1.5 for the short one
[04:38:11] <anonimasu> gotta finish the second motor mount tho..
[05:05:29] <Thiel> morning all here from Germany
[05:06:36] <Thiel> Question do i neet to put THIS->"setp parport.0.pin-04-out-invert 1"
[05:06:38] <Thiel> BEVORE or AFTER ->"net xdir => parport.0.pin-04-out" in HAL
[05:08:17] <micges> generally is good to config pins after connecting them, but in above it doesn't really matter
[05:08:46] <Thiel> thanks
[05:28:43] <Thiel> micges: whar are this resets for setp parport.0.pin-05-out-reset 1
[05:28:58] <Thiel> What
[05:29:21] <Thiel> do they pull the port after etch step back
[05:30:06] <Thiel> as i see they are set on every STEP output port
[05:31:36] <micges> who? where?
[05:32:37] <Loetmichel> anonimasu: i got about 4,2M/min out of the big CGantry i designed. 6m/min was planned but i made the ballscrewsa to thin so the began vibrating at F4300 was sufficient , bu you wiushed sometines a bit faster because the machine hat 1,5m*1,02m mopvement in a and x
[05:32:43] <Loetmichel> -a+y
[05:32:47] <micges> Thiel:
http://www.linuxcnc.org/docs/html/hal/parallel_port.html#_parameters
[05:55:22] <anonimasu> Loetmichel: hehe, think that's fast enough for that envelope?
[06:23:20] <Loetmichel> anonimasu: barely
[06:23:22] <Loetmichel> +e
[06:25:22] <Loetmichel> http://www.cyrom.org/MC/balsakopter_fraesen.avi <- moving there with F2400 outside the material
[06:28:15] <Loetmichel> ... and tahts annoying slow if you have to cross the whole table ;-)
[07:18:38] <anonimasu> Loetmichel: i mean for mine
[07:19:01] <anonimasu> i just got asked to make 1000 parts for someone.
[07:19:37] <Loetmichel> ah
[07:20:01] <anonimasu> some enclosure work milling some holes
[07:20:20] <Loetmichel> so time is an issue, i see. Is your CNC capable of milling at such speeds?
[07:20:34] <Loetmichel> i.e: do you have a highspeed-spindle?
[07:20:43] <anonimasu> 36k rpm..
[07:20:53] <Loetmichel> should be sufficient
[07:21:00] <Loetmichel> then: go for speed ,-)
[07:27:13] <anonimasu> got a idea about feed/speeds for abs?
[07:43:27] <de|> I'm not able to register on the forums so I'll try here

[08:58:18] <JT-Shop> it usually hurts when I tumble on small wooden parts
[09:00:07] <mrsun> hurts ?
[09:03:42] <Loetmichel> hrhr
[09:04:23] <Loetmichel> JT-Shop, you are a troll, and a good one i must confess ;-)

[10:32:36] <anonimasu> what do you quote to cut a 3 minute part?
[10:32:56] <Jymmm> how many and how hard?
[10:33:11] <taiden> that's a fun message to hear with no context
[10:33:25] <anonimasu> some holes in plastic enclosures
[10:33:37] <anonimasu> qty up to 1000
[10:33:51] <archivist> 3 minutes to cut but an hour to setup
[10:34:41] <archivist> dont forget part changing and packing/unpacking time
[10:34:47] <Jymmm> anonimasu: 1000 pcs or 1000 holes?
[10:34:48] <anonimasu> they are more like 1 minute.. with production feeds but i didnt feel like experimenting
[10:35:08] <anonimasu> like 1000pcs with 3 milled holes per part
[10:35:25] <syyl> we charge the full time for such jobs
[10:35:46] <archivist> worth jigging to do n off per run
[10:35:47] <syyl> job takes x hours, you pay x hours
[10:36:05] <syyl> theres all included, fixtures, setup, programming, ..
[10:36:58] <syyl> and my 5 minutes to get a coffee
[10:38:41] <taiden> does linuxcnc 2.5.0 support G52?
[10:39:38] <taiden> trying to find the best way to quickly write code to cut mutiple parts on a fixture
[10:40:22] <anonimasu> im thinking this, for short run they pay my hands on time with standard shop rate, for a larger run they pay fixture time + reduced pay per hour since i dont have to babysit the mill.
[10:41:10] <anonimasu> (my hands on time is lik 75 eur/hour) and for running a machine it's like roughly 55 eur/hour)
[10:41:31] <anonimasu> syyl: does that sound sane?
[10:41:46] <syyl> we charge 68eur/hour
[10:41:48] <cpresser> taiden: you might consider to use G92
[10:41:50] <syyl> regardles what we do
[10:42:03] <syyl> sheetmetal work, cad/cam work, manual machining, cnc setup
[10:42:12] <syyl> just about anything
[10:42:18] <syyl> but
[10:42:26] * cpresser is in the same range; i carge 60E
[10:42:33] <syyl> that are internal costs for the company
[10:42:48] <syyl> as we only do work for other departments
[10:43:28] <taiden> cpresser: G52 looked so easy to use though :)
[10:43:46] <syyl> but 50 to 70eur is a common charge for machine shops here
[10:44:35] <syyl> some have lower charges, when a machine runs without personel
[10:44:53] <syyl> like 30eur/h when setup and running
[10:45:32] <cpresser> i usually change my rates depending on the project
[10:46:07] <cpresser> another important thing is the time-frame. I charge up to 200E/h it its a job over the weekend
[10:46:27] <syyl> that sounds fair
[10:46:27] <anonimasu> this implies a single run of 1000 parts at once.
[10:46:43] <anonimasu> if they want small runs they pay a hour of fixture/set up time per run
[10:47:58] <anonimasu> i were planning on setting up the lathe for a run of shafts meanwhile.
[10:49:50] <Jymmm> setup fee + per part fee + holes per part fee
[10:50:41] <anonimasu> my runs are always one off most of the time so quoting stuff for serial production is a bit heavier
[10:52:13] <anonimasu> also, slow machine, cant really charge customers because my eqipment is not new :)
[10:54:25] <cpresser> anonimasu: only if the customer is aware of the fact that you machine is slow :D
[10:55:51] <anonimasu> well, i deliver what they need with the accuracy they need as quick as they need. :)
[10:56:00] <anonimasu> i could pull off 1000 of them in 20 hours.
[10:56:26] <taiden> oh so G52 isn't even implemented at all? is there a specific reason? MDI gives an error when I try to use it
[10:56:43] <JT-Shop> taiden: all the g codes are listed in the manual
[10:57:13] <taiden> http://linuxcnc.org/docs/html/gcode.html ?
[10:58:56] <JT-Shop> that or
http://linuxcnc.org/docs/html/gcode/gcode.html
[11:08:54] <tjb1> About to order extrusions, anything I should do before placing the order?
[11:08:55] <taiden> can you define g54 within an ngc file?
[11:09:16] <taiden> all my fixtures have different part zeros so it seems like it would be silly for me to use that if it's "hard coded" into the ini file
[11:14:38] <cpresser> g54 is 'soft coded' into emc.var
[11:15:41] <skunkworks> taiden: look at G10
[11:15:42] <cpresser> there are 10 systems available (G54.. G59.3), if that is equal or less the numer of fixtures you use, go for it :)
[11:16:10] <taiden> i'm planning on using 16
[11:16:24] <taiden> i had my heart set on g52 after reading up on it so im not sure what to use now :)
[11:16:55] <taiden> i'll look at g92
[11:17:39] <taiden> i tried to set a Z axis zero with g10 for g54 but it wont zero
[11:17:50] <taiden> g10 l2 p1 x0 y0 z0
[11:17:54] <taiden> only zeros x and y
[11:18:52] <taiden> quite amusing, i dont believe i made an error but i am only human :0
[11:18:55] <taiden> :)
[11:22:10] <skunkworks> that sets the machine offset to 0 (clearing the offset)
[11:23:11] <skunkworks> what you want probably is G10 L20
[11:24:13] <delkin> Does anyone, here, have experience with these drivers?
http://s963.photobucket.com/albums/ae118/infoshine15/?action=view¤t=2-9.jpg I've been trying to figure in which position I should leave the dip-switches (decay/microstepping). I still don't understand what they are for nor the consequences if they are not well set. Can someone help?
[11:25:21] <archivist> where did you get the driver from, thay should have instructions
[11:25:44] <skunkworks> http://www.youtube.com/watch?v=u5CmCzVUyk4
[11:25:48] <JT-Shop> taiden: do you have any g92 offsets on Z by chance
[11:25:52] <archivist> ie read the rest of the ebay page
[11:25:56] <taiden> nope
[11:26:54] <taiden> i want to start from home
[11:27:06] <taiden> and define x y z zero point at the center of all my workpieces
[11:27:27] <taiden> and then have it do cut.ngc on the zero of first, then go to the next zero and run again,
[11:28:39] <taiden> this twists my knickers
[11:28:48] <taiden> G53 x0 y0 z0
[11:28:54] <taiden> G10 L2 P1 x0 y0 z0
[11:28:56] <taiden> G54 x0 y0 z0
[11:29:07] <taiden> "linear move would exceed joint 0 negative limit"
[11:29:57] <JT-Shop> G54 only "selects" a coordinate system
[11:32:05] <taiden> i think emc2 reads it as
[11:32:06] <taiden> G54
[11:32:07] <taiden> x0 y0 z0
[11:32:19] <taiden> because it does make feed rate linear moves when i do it as above
[11:32:31] <taiden> (except for the error)
[11:33:00] <taiden> but apparently i had g92 offsets (which someone nailed in the beginning)... quite the humbling learning experience gcode is :)
[11:33:36] <delkin> archivist: I got it from ebay
http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CFwQFjAA&url=http%3A%2F%2Fduxe.ru%2Fload%2FTB6560HQ%2520T3%2520blue.pdf&ei=1Y7oT_isLaek0QWM8qHvCA&usg=AFQjCNFDlrOo0xzapwJM-lUbFqr3A_LWMw&sig2=CSGvYLMScWhOBAX4Z0wOpg , and I am having a hard time trying to understand what it means. It seems written in chinenglish.
[11:34:45] <taiden> alright i decided to use g92 based on cpresser 's recommendation and i think it will work nicely
[11:35:54] <taiden> i will use g53 to move the tool to each workpiece center
[11:36:09] <taiden> and g92 x0 y0 to set zero
[11:36:14] <taiden> then run the code
[11:36:18] <taiden> then on to the next one!
[11:36:32] <archivist> delkin, and scrolling through to section 8 where the switch is defined
[11:37:27] <JT-Shop> taiden: don't forget a G92.1 after each use of G92!
[11:37:39] <anonimasu> it always is like that call a coordinate system the make a rapid to start point
[11:37:41] <JT-Shop> or you will be left with an offset that might suprise you
[11:37:48] <delkin> archivist: that is my point. I still dont understand if I should go for fast decay, 50%, ... And the microstepping 1, 1/2, 1/8... If I choose the wrong one can I burn the driver?
[11:37:49] <taiden> alright I will do that
[11:37:51] <anonimasu> rapid down to clearence plane
[11:37:53] <taiden> shouldn't g53 ignore that though?
[11:38:03] <anonimasu> delkin: no
[11:38:15] <JT-Shop> yes it does but your next program you run will not ignore it
[11:38:27] <anonimasu> taiden: only thing that will kill your driver quickly is forgetting to set a current limit
[11:38:50] <archivist> delkin, try it, but dont fiddle with the power on, nor unplug motors when powered
[11:41:57] <archivist> delkin, for backup documentation get the chip datasheet for the driver TB6560
[11:47:07] <taiden> any ideas why gedit is dropping syntax highlighting as soon as i write an ngc file to disk?
[11:47:49] <delkin> archivist: Nice! Please tell me if this reasoning does make sense: The stepper motors I am gonna use have 1.8A/phase, so I am gonna set the current dip-switch to T1:ON T2:OFF (75%*2.5A).
[11:47:49] <jdh> did it have an extension before you saved it?
[11:48:47] <taiden> it was just in gedit limbo before it was saved as an ngc
[11:48:54] <taiden> no i lied
[11:48:56] <taiden> it was an ngc
[11:49:00] <taiden> my mistake
[11:49:05] <taiden> before and after saving
[11:49:14] <jdh> then, no clue :)
[11:49:17] <taiden> me either
[11:49:31] <taiden> quick rant: I love the heart and soul behind open source software
[11:49:43] <taiden> but I always seem to find really bizarre quirks in most open source software
[11:50:43] <jdh> I'm sure they will gladly accept your patch.
[11:50:54] <taiden> haha that's the problem
[11:51:17] <taiden> im not fluent in every language to patch each piece of software i use
[11:51:28] <taiden> if everything was in python then i'd give it a whirl
[11:52:54] <archivist> delkin, I didnt keep the pdf open, sounds about right
[11:58:48] <delkin> archivist: ok man, thanks for the support!
[12:00:02] <taiden> alright so i have my part cut file
[12:00:22] <taiden> and i have my ngc that locates all the parts on a fixture
[12:00:22] <taiden> what's the most simple way to put them together?
[12:00:34] <taiden> can i just do an import part.ngc or something similar
[12:00:36] <jdh> make the cut a sub, set coords, call, repeate?
[12:01:21] <syyl_ws_> mh
[12:01:40] <syyl_ws_> having a rough casting for a angleplate laying around for two years
[12:01:45] <alex4nder> yoh
[12:01:46] <syyl_ws_> maybe time to machine it...
[12:02:01] <taiden> would like to be able to call from an external file so I can swap in new part cut file with ease
[12:03:10] <JT-Shop> call what?
[12:06:48] <taiden> the part cut
[12:06:59] <taiden> am I just doing everything in an unorthodox manner?
[12:07:07] <IchGuckLive> Hi all micges Thanks for helping some people today out of my company on parport action
[12:07:46] <IchGuckLive> taiden: you load tooltable and reload g-code done
[12:08:01] <taiden> ?
[12:08:07] <IchGuckLive> taiden: with G41/42 in g-code
[12:08:21] <taiden> i'll catch you up IchGuckLive,
[12:08:34] <taiden> i made gcode file to cut a part, and another gcode file to locate all the parts on a fixture
[12:08:39] <IchGuckLive> taiden: dis you access buildbot master
[12:08:43] <taiden> just trying to put them together
[12:09:09] <taiden> the fixture code uses g92 to set zero
[12:09:15] <IchGuckLive> the other parts have Diverent G5x
[12:09:17] <taiden> just need to call the part cut after each g92
[12:09:38] <taiden> nope, just g92 and thats it
[12:09:58] <IchGuckLive> so you are partzero G54
[12:10:02] <taiden> i use g53 to locate each part from machine zero and g92 to set zero
[12:10:13] <taiden> probably g54 if that's default
[12:10:14] <taiden> yea
[12:10:28] <taiden> i thought g92 was completely separate though
[12:10:51] <IchGuckLive> you are doing it te wrong way as i ment to use G5x fotr the other parts on the Fixure
[12:10:58] <taiden> i have 16 parts
[12:11:11] <taiden> not enough g5x for that
[12:11:24] <IchGuckLive> 16 identical parts
[12:11:26] <taiden> yeah
[12:11:41] <IchGuckLive> why not departing G-code to etch location
[12:11:49] <taiden> i dont follow
[12:12:00] <taiden> "departing"?
[12:12:20] <IchGuckLive> is the space defined on every part
[12:12:33] <IchGuckLive> or free fixure to all
[12:12:49] <taiden> part center is x0 y0 in my part cut file
[12:12:57] <taiden> i have gcode that located part center on my fixture
[12:13:04] <taiden> i just need to call my part cut file after each relocation
[12:13:11] <taiden> they are two separate files
[12:13:18] <taiden> fixture.ngc and part.ngc
[12:13:19] <IchGuckLive> no i mean are they in wrows
[12:13:22] <taiden> yes
[12:13:30] <taiden> 4 x 4
[12:13:48] <IchGuckLive> only this 16 or are there more to come on the same position
[12:13:55] <taiden> more
[12:14:02] <taiden> i already have the code all set up
[12:14:03] <IchGuckLive> so 16 every cut
[12:14:07] <taiden> yes
[12:14:15] <taiden> i just need to call my part cut file in my fixture file
[12:14:19] <taiden> that's all i need at this point
[12:14:21] <taiden> everything else is solved
[12:14:27] <IchGuckLive> is the G-code secret or can we get alock on ti
[12:14:32] <taiden> you can look at it
[12:14:33] <taiden> one sec
[12:14:33] <IchGuckLive> it B)
[12:14:42] <taiden> i'll pastebin it just give me a second
[12:16:14] <taiden> hate doing stuff with two computers :)
[12:16:21] <IchGuckLive> im asking for it on working with simple python to multiply your part g-Code
[12:16:30] <taiden> well
[12:16:34] <taiden> i'd much rather call from file
[12:16:41] <taiden> that way i can just make minor edits to the part file
[12:16:47] <taiden> and it will cascade through to my fixture file
[12:17:16] <IchGuckLive> ok its your turn on how it might work out
[12:17:19] <taiden> if this is beyond the scope of gcode i can find a different solution
[12:17:37] <taiden> http://linuxcnc.org/docs/html/gcode/o-code.html#sec:subroutines
[12:17:39] <taiden> i found this but
[12:17:46] <taiden> the example is confusing
[12:17:54] <IchGuckLive> if i got 1Mio part in 16 locations i woudt stay G54 ans get the G-code to all the 16 Locations
[12:18:11] <taiden> yeah but then you have 16 different pieces of code for the same part
[12:18:17] <taiden> with different XYZ numbers
[12:18:28] <taiden> if you have to make minor changes it becomes ridiculous
[12:18:35] <taiden> right?
[12:18:47] <IchGuckLive> no
[12:19:04] <IchGuckLive> you chabnge the main part and run the ofset script
[12:19:13] <taiden> apparently internet on my cnc computer is not working
[12:19:14] <IchGuckLive> oh my english
[12:19:22] <taiden> so i can't send you the file
[12:19:27] <taiden> but what it does is this
[12:19:33] <IchGuckLive> how many lines
[12:19:38] <IchGuckLive> <5k
[12:19:44] <taiden> my part file is 150 lines
[12:19:50] <taiden> since i wrote it by hand
[12:20:03] <taiden> my fixture file is about 40 lines
[12:20:09] <IchGuckLive> cand you depart it by USB stick
[12:20:17] <taiden> yes
[12:20:25] <micges> IchGuckLive: welcome
[12:20:38] <IchGuckLive> micges: THANKS
[12:20:43] <taiden> fixture file:
[12:20:53] <taiden> G53 G0 X1 Y1 ( first part zero )
[12:20:55] <JT-Shop> taiden: you can "call" a subroutine in a file and pass it parameters
[12:21:00] <taiden> G92 X0 Y0
[12:21:05] <taiden> ( part file call )
[12:21:09] <taiden> G92.1
[12:21:11] <JT-Shop> for example
[12:21:12] <IchGuckLive> micges: i warsonRoute today and they did Fire up the 5Axis with minor problems
[12:21:13] <taiden> next section
[12:21:39] <JT-Shop> o<cutfile> call [1.234] [2.345]
[12:21:47] <taiden> http://linuxcnc.org/docs/html/gcode/o-code.html#sec:subroutines
[12:22:00] <taiden> i found this but i can't figure out how that works
[12:22:09] <taiden> cutfile.ngc
[12:22:16] <taiden> ocutfile sub >>> etc etc
[12:22:20] <taiden> ?
[12:22:32] <JT-Shop> read section 6 of the link
[12:22:37] <taiden> yeah
[12:22:42] <JT-Shop> it shows an example
[12:22:50] <taiden> i read it a few times :)
[12:22:59] <taiden> what is <cutfile> in plain text
[12:23:04] <JT-Shop> see the "called file example"?
[12:23:07] <taiden> yes
[12:23:15] <taiden> do oyu leave the <> in
[12:23:19] <taiden> or is that supposed to be not there
[12:23:25] <JT-Shop> that is the syntax if the subroutine file
[12:23:43] <taiden> so that is exactly what it should be
[12:23:47] <JT-Shop> see how the name of the file and the sub must be the same?
[12:23:50] <taiden> i thought the <> was to be substituted
[12:24:57] <JT-Shop> see the difference between calling a named file and a numbered file?
[12:25:09] <taiden> yeah
[12:25:38] <taiden> so what if i wanted to run the part file as a single part later
[12:25:49] <taiden> can i just load it and run? or do I need to make a ngc that calls it
[12:25:56] <JT-Shop> call it in the MDI tab
[12:26:08] <taiden> that makes sense
[12:26:13] <taiden> so then just
[12:26:20] <taiden> o<cutfile> call
[12:26:24] <taiden> and it will do it's thing
[12:26:31] <JT-Shop> also note you can pass the X and Y coordinates to your file as a variable
[12:26:44] <JT-Shop> JT-Shop> o<cutfile> call [1.234] [2.345]
[12:26:56] <taiden> wait
[12:26:58] <taiden> so then
[12:27:01] <taiden> does that define zeros?
[12:27:23] <JT-Shop> yes, if you program it to do so
[12:27:24] <jdh> your sub can do whatever it wants with the args
[12:27:30] <taiden> so it just passes it as a variable
[12:27:34] <taiden> which you have to handle in your subroutine
[12:27:36] <JT-Shop> aye
[12:27:40] <JT-Shop> aye
[12:27:41] <taiden> alright
[12:27:47] <taiden> just like any other programming language
[12:27:51] <JT-Shop> I see a lightbulb
[12:27:51] <taiden> :)
[12:28:02] <IchGuckLive> O:O
[12:28:06] <IchGuckLive> O.O
[12:28:07] <taiden> gcode is both stupid and smart haha
[12:28:27] <taiden> like the lookahead for tool compensation is really neat
[12:28:39] <JT-Shop> please read this
http://linuxcnc.org/docs/html/gcode/overview.html#_parameters_variables_a_id_sec_parameters_a
[12:28:56] <taiden> will do
[12:30:59] <taiden> thanks all
[12:31:04] <taiden> we'll see how this works out
[12:32:18] <taiden> "unable to open file <square>"
[12:32:27] <taiden> i have my subroutine directory set in .ini
[12:32:39] <taiden> and my square.ngc in that directory
[12:34:45] <IchGuckLive> taiden: woudt be esyer for us to get a look into the gcode to see what you expect to help you
[12:35:11] <taiden> I think I got it, thanks IchGuckLive
[12:35:19] <IchGuckLive> NP
[12:35:54] <JT-Shop> taiden: did you create the subroutine file as the example shows?
[12:35:58] <taiden> yes
[12:36:01] <taiden> i got it to load
[12:36:08] <JT-Shop> ok
[12:36:09] <taiden> but when it reaches the call line the program just halts
[12:36:37] <JT-Shop> does your subroutine do anything?
[12:36:38] <IchGuckLive> you need to prozess the vars to your X Y Z
[12:37:12] <taiden> yeah
[12:37:17] <taiden> right now it just does a square
[12:37:22] <taiden> in xy plane
[12:37:35] <JT-Shop> can you pastebin the subrounine file?
[12:37:42] <JT-Shop> and the line you used to call it
[12:37:47] <taiden> i'll see if i can get internet working on the cnc computer
[12:39:10] <taiden> OK
[12:39:13] <taiden> square.ngc
[12:39:32] <taiden> http://pastebin.com/wTXhirk7
[12:39:39] <taiden> fixture.ngc
[12:39:49] <JT-Shop> drop the %'s
[12:39:55] <taiden> ok
[12:41:16] <taiden> SUCCESS
[12:41:22] <taiden> ultimate success
[12:41:26] <taiden> thanks all
[12:41:36] <taiden> once it works it's so easy, but getting there can be rough
[12:41:59] <JT-Shop> http://pastebin.com/Zbkc1VnY
[12:42:07] <jdh> gcode, or women?
[12:42:11] <JT-Shop> ouch
[12:42:16] <taiden> both haha
[12:42:50] <taiden> alright gents now im off to cut absurd amounts of parts !
[12:43:03] <JT-Shop> pastebin.com/a4TavjSw
[12:43:07] <JT-Shop> see that one
[12:43:16] <taiden> yep
[12:43:21] <taiden> that's what did it for me, thanks JT
[12:43:38] <JT-Shop> see how I used the variables for the part center?
[12:43:44] <taiden> oh yeah
[12:43:47] <taiden> i do
[12:43:59] <taiden> that's clever
[12:44:05] <taiden> so then you can just do
[12:44:08] <JT-Shop> o<square> call [1.234] [2.345]
[12:44:12] <taiden> yeah
[12:44:16] <JT-Shop> aye
[12:44:17] <taiden> holy moly
[12:44:23] <taiden> < mind blown
[12:44:40] <taiden> i could even set
[12:44:45] <JT-Shop> aye
[12:44:45] <taiden> variables for the final outside radius
[12:44:52] <taiden> and then do part variations
[12:44:53] <JT-Shop> up to 30!
[12:44:55] <taiden> from my fixture file
[12:45:01] <taiden> good lawd
[12:45:11] <JT-Shop> now you have smoke coming out of your ears
[12:45:18] <taiden> well it's funny
[12:45:24] <taiden> this part used to take me 2 hours to make on the lathe
[12:45:27] * JT-Shop goes to make some chips
[12:45:35] <taiden> now it takes 4 minutes
[12:45:43] <taiden> and NOW i will be able to make 16 at a time
[12:45:46] <taiden> while I finish the last 16
[12:45:55] <JT-Shop> there you go
[12:46:04] <taiden> thats an increase in production of
[12:46:12] <taiden> a gazillion percent
[12:46:23] <JT-Shop> time to squeeze in a nap
[12:46:29] <taiden> thanks again JT
[12:54:57] <IchGuckLive> taiden you got it
[12:55:12] <IchGuckLive> or shoud i post a example

[13:41:32] <JT-Shop> 6061
[13:42:25] <Tom_itx> mmm tasty
[13:44:20] <jdh> with ranch flavored coolant.
[14:02:20] <bostjan_2> Hello!
[14:03:53] <bostjan_2> I have 10.04 Ubuntu with EMC, on that machine i have radeon x1650 graphic and if someone know, is there any trouble if i put also ATI drivers on (like RTOS problems). Now, my desktop effect are not working. But they are so cool..
[14:21:02] <bostjan_2> Does anyone know, could i try with ATI linux driver?
[14:25:05] <micges_> surely you can try
[14:25:20] <bostjan_2> Experiences??
[14:25:27] <JT-Shop> a CNC machine with desktop effects seems so wrong...
[14:25:40] <bostjan_2> As i dont want to mess EMC..
[14:26:04] <micges_> but imo you should focus on making system as stable as possible, not on decorations
[14:26:32] <bostjan_2> JT-Shop: You are right!!
[14:28:54] <bostjan_2> Another question. How do you guys do a toolenght probe, i mean software part in EMC...
[14:31:15] <JT-Shop> probe input
[14:31:49] <micges> bostjan_2: you must have some sensor, connect it in some way into pc (parport, mesa) and connect it's signal to motion.probe-input
[14:32:29] <micges> then read this:
http://www.linuxcnc.org/docs/html/gcode/gcode.html#_g38_x_straight_probe_a_id_sec_g38_probe_a
[14:32:32] <bostjan_2> Ok, i have that connected to LPT input pin.
[14:35:07] <bostjan_2> Guys, there is so much of learning, but im going into.. Thanks.
[14:35:26] <JT-Shop> this might help
http://linuxcnc.org/index.php/english/component/kunena/?func=view&catid=21&id=18843&limit=6&start=6#18884
[14:37:29] <bostjan_2> And another, just curious. Kress FME1050, does anyone uses it??
[14:41:01] <micges> my friend is using, but I don't remember if 800 or 1050
[14:43:19] <Loetmichel> bostjan_2: h have usede the predecessor
[14:43:26] <Loetmichel> the FM9660E
[14:44:09] <bostjan_2> Did someone has remote rpm speed from EMC??
[14:44:23] <Loetmichel> its okay, the bearings are done for after about a year 8h/5d/week work
[14:44:27] <Loetmichel> it IS possible
[14:44:49] <Loetmichel> but it need some nodification on the speed control ciruit inside the kress
[14:46:20] <bostjan_2> Loetmichel: do you know how it can be done. im quite an electronic guy...
[14:49:34] <Loetmichel> in short: replace the variable resistor for speed with two Opto Couplers and put an PWM signal to them, inverted on one and straight on the other. 2 RC-filters across the transistors of the coupter cant hurt, either
[14:49:47] <Loetmichel> careful: the speed PCM is LIVE!
[14:49:50] <Loetmichel> PCB
[14:57:51] <bostjan_2> Dont worry about live mains. When i am testing that stuff, im working with isolative 220/220 transformer. As i see, basically PWM does quite speedy switchung from full to minaimal speed, so PWM approximation is the potentiometer level. Does the mid potentiometer contact needs to have capacitor??
[14:59:26] <bostjan_2> Another one. Does anyone has REMOTE control of EMC machine PC. I would like to move monitor, keyboard and mice away because of dust..
[15:04:12] <Loetmichel> hmmm
[15:04:21] <Loetmichel> i do this via VNC
[15:04:25] <Loetmichel> works
[15:05:12] <bostjan_2> Loetmichel:Satisfied (i mean speed and reliability). What is the display resolution you get??
[15:05:16] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13060 <- supervising the mill while sitting int hte bathtub ;-)
[15:05:58] <Loetmichel> even the webcam runs more or less fluently via VNC
[15:06:20] <bostjan_2> EXCELLENT!!!!
[15:11:47] <Connor> Okay, so, I saw some code some where that allowed jogging and touch off for manual tool changes..
[15:14:58] <Loetmichel> bostjan_2: be warned: my Linuxcnc-machine is a industrial board with a C2d 2,x GHZ
[15:15:31] <Loetmichel> and it runs nearly full load when VNC AND webcam AND linuxCNC are active
[15:17:34] <bostjan_2> C2D is??
[15:18:19] <Loetmichel> core two duo
[15:19:07] <Loetmichel> 2,8GHz iirc
[15:19:14] <bostjan_2> I have Core2DUO on 2,2 Ghz (Dell 330), so it should work. Maybie i will do also a Webcam VLC encoding and streaming directly..
[15:20:26] <Loetmichel> mine is in a "pizzabox"
[15:20:28] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12265
[15:20:33] <Loetmichel> underneath the Mill

[15:21:53] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12569
[15:21:59] <Loetmichel> (complete system)
[15:22:23] <Loetmichel> and the silicone keyboards are useable
[15:23:38] <Loetmichel> nothing to type long sagas, but ok for the machine. and: waterproof and even glowing parts dont go through
[15:23:59] <bostjan_2> Good idea, rubber silicone keyboard. You can spill on it.. Nice workshop you have there.
[15:25:46] <Loetmichel> bostjan_2: more important then spilling: the swarf have no chance to block keys
[15:26:08] <Loetmichel> they cant get underneath any mechanics, 'cause there isnt any ;-)
[15:27:23] <bostjan_2> Loetmichel:Are you from Germany??
[15:27:59] <Loetmichel> yes
[15:29:13] <Loetmichel> why?
[15:33:48] <bostjan_2> Just courious. Traditional german precision.. I cant show you mine images yet. Maybie in few days..

[15:48:14] <Tom_itx> gday
[16:01:01] <syyl_> that was sitting under the bench for two years, now i managed getting started on it..
[16:01:03] <syyl_> https://dl.dropbox.com/u/24396704/IMG_0606.jpg
[16:01:09] <syyl_> https://dl.dropbox.com/u/24396704/IMG_0618.jpg
[16:08:36] <andypugh> So, how hard is it to set up a PXE boot server?
[16:13:32] <bostjan_2> Loetmichel:Thanks for your info!!
[16:18:00] <mrsun> syyl_, alu or cast iron ? :)
[16:18:09] <syyl_> cast iron of course :)
[16:18:30] <mrsun> is angle shlefs in alu any usefull ? :)
[16:18:59] <mrsun> i want to be able to melt cast iron =)
[16:19:57] <syyl_> for your relief, i didnt make that casting :D
[16:20:14] <mrsun> =)
[16:20:20] <mrsun> still want to be able to melt cast iron =)
[16:24:49] <mrsun> thinking of modifing my alu furnace some, as its at the end of its says i could try and have it oil fired to see how high a temperature i can get =)
[16:25:11] <syyl_> cast iron would be great
[16:25:20] <Loetmichel> mrsun: do you have a cuicible capable of carriing molten steel?
[16:25:21] <Loetmichel> ;-)
[16:25:36] <syyl_> thats the least problem
[16:26:01] <mrsun> Loetmichel, graphite
[16:26:03] <mrsun> :P
[16:26:10] <mrsun> tho its no good for iron realy
[16:26:38] <Loetmichel> mrsun: possible... if the heater is electric/inductive and the whole thing is in argon ;-)
[16:26:39] <mrsun> silicon carbide or whatever its called, isnt that the recomended type? :)
[16:26:40] <syyl_> silicone carbide is the right one, i think
[16:26:50] <syyl_> yeah ;)
[16:26:56] <mrsun> Loetmichel, thats where combusted fuel come into picture
[16:26:59] <mrsun> reducing flame
[16:27:01] <mrsun> no argon needed
[16:27:19] <syyl_> real men melt metal with a flame ;)
[16:27:28] <mrsun> thats one of the reason my steel crucible (made from like 1mm thick sheet metal) has standed out for like 50 melts :P
[16:27:30] <Loetmichel> ... as long as you dont move the graphite cruicible out of the oven to fresh air ;-)
[16:27:55] <mrsun> Loetmichel, the outer layer of graphite will burn off, then the rest is kind of protected by the clay ? :P
[16:28:04] <mrsun> they get eaten up over several melts
[16:29:07] <mrsun> electrical furnaces sucks when it comes to oxidisation
[16:29:17] <mrsun> as the oxygen will never get burned off
[16:31:29] <Loetmichel> hmm
[16:32:05] <Loetmichel> anyone tried to melt steel just in the cruicible by lowering two carbon rod connected to a walder from above?
[16:32:55] <mrsun> would kill the welding machine
[16:33:03] <mrsun> they arent made for continious duty ... :P
[16:36:08] <mrsun> sucks that cast iron is so hot you need special sand tho ... and coating the sand etc etc :/
[16:36:25] <syyl_> normal oilbond works
[16:37:25] <Loetmichel> mine is... up to 50A ;-)
[16:37:55] <Loetmichel> after that: it will simply shut off when overtemp occurs
[16:37:55] <mrsun> well sure at low amps they can deliver 100%
[16:37:59] <mrsun> mm
[16:38:13] <syyl_> with the 3,5kW you can draw from a 230V socket, ther e will not happen to much
[16:38:29] <syyl_> if you want to melt anything thats a usable ammount
[16:38:33] <Loetmichel> depends on the amount of steel to melt ;-)
[16:39:00] <syyl_> the amount of molten metal will not even fill the sprue of a mold :P
[16:39:05] <andypugh> Loetmichel: Sheffield Forgemasters?
http://www.sheffieldforgemasters.com/sfm/facilities/melt-shop
[16:39:12] <andypugh> 110 tonnes at a time..
[16:39:23] <Loetmichel> i have even seen videos where goldsmiths had melted gold or silver in a microwave
[16:39:45] <tjb1> Good luck with that
[16:40:22] <syyl_> i htought we were at steel?
[16:40:53] <Loetmichel> isnt that impossible. most modern microwaves are short-circuit-protected so the CAN work against a niear short
[16:41:08] <Loetmichel> and iron isnt even such a good conductor as silver or gold
[16:41:34] <Loetmichel> bur granted: the amounts were merely in the 10s of grams
[16:42:20] <syyl_> we could also call it "non practical"
[16:42:21] <syyl_> ;)
[16:42:46] <Loetmichel> well, if one wnats to cast an iron wedding ring...
[16:42:55] <Loetmichel> :-)
[16:43:13] <syyl_> iron needs about four times as much energy to melt as gold...
[16:44:29] <Loetmichel> so?
[16:44:55] <Loetmichel> iron is a much less good conducktor, so the energy deposited in the iron is much greater
[16:45:09] <Loetmichel> but as i said: thats for REAL slamm amounts
[16:45:18] <syyl_> as i said
[16:45:20] <syyl_> non practical
[16:45:54] <Loetmichel> the solution with a big welder (preferable three phase) and a small (10kg) cruicible should work
[16:45:56] <Loetmichel> imho
[16:46:09] <syyl_> 10kg?!
[16:46:22] <Loetmichel> yes
[16:46:51] <mrsun> oo gonna be nice weather tomorrow also, so there will be a day of modifying furnace + soldering in new thermo fuse in the SRS box for the car ... =)
[16:46:58] <mrsun> and a long nice run
[16:46:59] <Loetmichel> if the cruicible si a bit isolatong i see no problem in meting 10kg steel wirh a welder and graphite electrodes
[16:47:59] <syyl_> i will tell muellernick that its that easy ;)
[16:48:06] <andypugh> Induction
[16:48:19] <mrsun> you friends with muellernick ? :P
[16:48:27] <syyl_> yes
[16:48:39] <mrsun> =)
[16:48:40] <syyl_> he lives only ~120km or so from here
[16:48:43] <andypugh> http://webpages.charter.net/dawill/tmoranwms/Elec_IndHeat1.html
[16:48:47] <Loetmichel> syyl_:_ THEORETICAL
[16:48:51] <syyl_> thats where i do my casting
[16:48:55] <syyl_> :)
[16:48:55] <mrsun> oh =)
[16:49:10] <mrsun> hes done some nice videos =)
[16:49:15] <andypugh> (And imagine bringing that project up to date with an Arduino to do the sequencing and adaptive frequency)
[16:49:37] <syyl_> i will tell him :)
[16:49:45] <syyl_> going to see him on saturday
[16:49:46] <andypugh> Doh! I just _copied_ the iso to a liveCD
[16:49:50] <mrsun> i would go for induction rather then arc for small melts i think
[16:50:02] <syyl_> backup is always good, andypugh ;)
[16:50:29] <mrsun> syyl_, his videos has been quite instructive while i was scraping my mill =)
[16:51:59] <syyl_> :)
[17:03:38] <JT-Shop> Loetmichel: here is what I have so far
http://imagebin.org/217815
[17:05:46] <Loetmichel> looks nice, but i would invert the x asis
[17:05:49] <Loetmichel> axis
[17:06:34] <Loetmichel> will be more rigid if the x is a closed rectangel with the bars protunding top and bottom
[17:07:02] <Loetmichel> and then the x sled made in a C-shape out of aluminium with the bearings inward
[17:08:26] <JT-Shop> I think I follow your idea
[17:10:44] <JT-Shop> would you run the X axis bars horz to each other?
[17:10:57] <JT-Shop> now they are vert to each other
[17:12:24] <Loetmichel> ?
[17:12:52] <Loetmichel> no, but outside of the wooden box that buolds the gantry
[17:12:58] <Loetmichel> on top and bottom
[17:19:51] <Loetmichel> btw: you make the same error as many others: the gantry sides are to weak
[17:20:02] <Loetmichel> make them double an boxes also
[17:20:33] <JT-Shop> OK, I was working on that and was not happy with what I had so far
[17:22:19] <Loetmichel> JT-Shop you have seen THAT?
[17:22:33] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=11205
[17:22:36] <JT-Shop> what?
[17:22:39] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=11175
[17:22:49] <JT-Shop> no
[17:23:02] <Loetmichel> now you have
[17:23:14] <Loetmichel> for inspiration on the gantry sides ;-)
[17:23:15] <JT-Shop> I see now
[17:23:25] <JT-Shop> how did you hold the X axis rails?
[17:24:09] <Loetmichel> that are sipported rails
[17:24:11] <JT-Shop> so you used a set back too to get the tool over the table
[17:24:13] <Loetmichel> supported
[17:24:18] <JT-Shop> ok like the Y
[17:24:34] <Loetmichel> right
[17:24:45] <Loetmichel> i only helped to buold that machine
[17:24:56] <Loetmichel> its from a friend
[17:25:06] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_view=core.DownloadItem&g2_itemId=11178
[17:25:08] <JT-Shop> I like the gantry
[17:26:41] <Loetmichel> :)
[17:26:47] <Loetmichel> its a bit bigger
[17:27:04] <JT-Shop> yes, but the design is scalable to my little toy
[17:27:08] <Loetmichel> 1600*1200*300mm movement iirc
[17:29:19] <mrsun> ough, cant sleep
[17:32:27] <r00t4rd3d> get high
[17:33:24] <taiden> well gents
[17:33:40] <taiden> now I can press a button and make 16 identical parts
[17:33:50] <taiden> thanks all for the help
[17:33:53] <andypugh> I tend to agree with Loetmichel, I think that that design could do with a bit more stiffness in the Y. Just extending the bits at right angles to the sides all the way down to the bearing blocks would help.
[17:35:12] <Tom_itx> i was gonna say the same thing but the phone rang and you beat me to it
[17:35:44] <JT-Shop> that's why I post the photos for more idea :)
[17:35:49] <JT-Shop> taiden: cool
[17:36:07] <Tom_itx> i'm looking for a design link along the same lines
[17:38:18] <Tom_itx> well you know how linear slides are made
[17:38:30] <Tom_itx> was similar using the slotted bearings like i suggested
[17:38:40] <Tom_itx> wrapped around the axis like a C
[17:40:13] <Tom_itx> http://www.kickstarter.com/projects/openrail/openrail-open-source-linear-bearing-system?ref=card
[17:40:20] <Tom_itx> similar to that i guess
[17:40:46] <JT-Shop> V bearings
[17:40:53] <Tom_itx> yeah
[17:40:59] <JT-Shop> expensive
[17:41:03] <Tom_itx> i know
[17:41:19] <Tom_itx> but i thing radius'd bearings would have more contact surface
[17:41:33] <JT-Shop> and they wear funny due to the different diameters of contact
[17:41:59] <Tom_itx> do what you did on x only invert it and put the bearings on the outside
[17:42:39] <Tom_itx> and put spacers between the rails inside then
[17:43:11] <JT-Shop> that makes the bearing holders more complicated to make
[17:43:24] <Tom_itx> maybe not, but i see 'twist' in z the way it is
[17:43:43] <JT-Shop> hows that?
[17:44:23] <Tom_itx> if you're plunging it's gonna push up and the top rail will push up and back since the motor is on the side and not directly under it
[17:44:48] <Tom_itx> but we're talking about a wood router here too
[17:45:04] <JT-Shop> any way you mount the spindle it will be off center
[17:45:12] <Tom_itx> yeah
[17:46:07] <Tom_itx> bak to wiring...
[17:46:11] <JT-Shop> If I though bolt the top and bottom then it is really captured
[17:46:13] <Tom_itx> did you see what i did so far?
[17:46:16] <JT-Shop> no
[17:46:35] <Tom_itx> that's what i meant by puting spacers between the rails
[17:46:47] <Tom_itx> kinda like that extrusion stuff
[17:47:12] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/psu/control3.jpg
[17:47:23] <Tom_itx> gotta finish wiring the mesa boards now
[17:48:19] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/psu/control4.jpg
[17:48:27] <Tom_itx> hopefully i can get rid of most of that spagetti
[17:49:09] <JT-Shop> looking good
[17:49:21] <Tom_itx> the stepper wires are next
[17:49:59] <Tom_itx> i did the upper left bundle last night for step and direction to all
[17:50:15] <Tom_itx> single wire bundle
[17:50:47] <Tom_itx> i found a bunch of wire i forgot i had
[17:50:51] <tjb1> Whats that for Tom_itx
[17:51:03] <Tom_itx> a sherline :)
[17:51:12] <tjb1> Lots of caps :)
[17:51:12] <Tom_itx> think it'll handle it?
[17:51:23] <Tom_itx> yeah, they were surplus
[17:51:36] <Tom_itx> smaller values but still add up
[17:51:53] <Tom_itx> and i'm told less ripple that way than with one big one
[17:53:42] <Tom_itx> JT-Shop, actually those wood braces you have should eliminate most of the twist
[17:53:58] <Tom_itx> it might be better to put the bearings on the outside though
[17:58:59] <andypugh> If the LiveCD stalls after The name of the guy who created ISOLINUX (ie, after the very first line of text on screen) would that indicate that the machine in question probably can't run Lucid?
[17:59:34] <Tom_itx> mine kept giving me CD errors
[17:59:42] <Tom_itx> but i know the cd's are good
[18:00:03] <andypugh> I don't even get that far.
[18:00:06] <Tom_itx> even tried burning one uber slow
[18:00:26] <Tom_itx> no usb boot support or i would have tried that
[18:00:42] <andypugh> I have installed from USB using the image, but I too lack USB boot
[18:00:49] <andypugh> I am wondering about PXE boot
[18:01:29] <andypugh> But the fact that the package-manager upgrade left me with a machine that kernel-panic-ed on boot might also be a bad sign.
[18:02:25] <Tom_itx> i may just keep the box and get an atom to stuff in it
[18:02:35] <Tom_itx> it would look rather lonely in that big box though
[18:04:24] <andypugh> I re-installed Hardy/LinuxCNC. But couldn't log in. No idea why, I can only assume I miss-typed the password twice!
[18:04:32] <andypugh> So I am re-re-reinstalling.
[18:10:11] <r00t4rd3d> http://www.extremetech.com/computing/131656-the-fanless-heatsink-silent-dust-immune-and-almost-ready-for-prime-time
[18:14:13] <Tom_itx> cause lord knows no wires are gonna get caught in that
[18:14:54] <archivist> the air bearing is a thermal insulator...snake oil
[18:16:49] <djdelorie> the design assumes that a 1 thou air bearing is less of an insulator than the much thicker still air boundary on a normal heat sink
[18:16:50] <archivist> boundary layer is dependent on airflow, I see little difference to normal fan design
[18:30:15] <djdelorie> ah, but it's not a new *fan* it's a new *heatsink*
[18:32:43] <r00t4rd3d> im just glad someone is working on something better then the current crap setup that does not involve water.
[18:34:01] <r00t4rd3d> 5.25 air conditioner.
[18:34:23] <r00t4rd3d> that doesnt condensate
[18:34:48] <djdelorie> the sealed water ones are a decent compromise, assuming you have room for the radiator
[18:44:33] <r00t4rd3d> i just seen the biggest spider in my life in my cellar
[18:44:46] <r00t4rd3d> i had to hit it twice with the shovel to kill it
[18:45:29] <r00t4rd3d> and i normally just leave them alone
[18:45:43] <r00t4rd3d> this one had to go
[18:50:02] <andypugh> A huge one just ran across my living-room floor. I said "Hi" and let her be.
[18:51:03] <r00t4rd3d> i live in the country so bugs dont bother me normally
[18:51:31] * Loetmichel lives inside the city.
[18:51:37] <r00t4rd3d> when they are as big as my hand I have an issue
[18:51:55] <Loetmichel> but bugs normally dont annoy me
[18:52:47] <Connor> I saw some code or something a while back that allowed you to Jog and touch off for manual toolchange. Anyone know were that would have been and if it's working ?
[18:53:52] <Loetmichel> exept the bed(stink) bugs... they will die a mercieless death if spotted
[18:54:19] <andypugh> Connor: There is jog-while-paused but I don't think it allows touch-off.
[18:55:01] <Loetmichel> and the gnats of course
[18:55:20] <andypugh> There was a patched version of hal_manual_toolchange from (I think) Ed Nisley. There is also something from mhaberler but I can't recall how far that went
[18:55:42] <Connor> Grumble. Something so simple.... :(
[18:56:22] <andypugh> It's very far from simple, when you get into trying to make it work.
[18:59:01] <jdh> https://fbcdn-sphotos-a.akamaihd.net/hphotos-ak-prn1/521382_1015182558984
[18:59:02] <JT-Shop> much simpler to just break up your G code file...
[18:59:07] <jdh> oops
[18:59:13] <jdh> [12:22:56] <jdhNC> connor:
http://www.linuxcnc.org/index.php/english/component/kunena/?func=view&catid=21&id=18843&limit=6#18853
[18:59:52] <Connor> Yea, I keep hearing that.. But, I just find that totally insane.
[18:59:55] <mhaberler> connor: there are a few different things here - see master: configs/sim/remap/manual-toolchange-with-tool-length-switch (no jog)
[19:00:26] <mhaberler> then there's a jog-while-paused patch which wasnt integrated into master yet:
[19:01:12] <mhaberler> http://git.mah.priv.at/gitweb/emc2-dev.git/shortlog/refs/heads/jog-while-paused-preview1
[19:01:36] <mhaberler> that allows moving around during pause, but NOT touchoff
[19:02:13] <mhaberler> those two approaches are independent and should work in combination
[19:02:40] <andypugh> Connor: If you are interested, there is an explanation of the problem here:
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?WhyManualWhilePausedIsHard
[19:03:08] <andypugh> Folk are working on whittling away at the problems, it wil come eventually
[19:03:52] <mhaberler> then there's the Les Newell patched hal_manualtoolchange thing which does an abort at toolchange, lets you mdi/jog around, and then automatically run-from-line past the m6 line (within the restrictions of run-from-line)
[19:04:36] <Connor> mhaberler: Issue with that is, you best make sure your back were you need to be before starting up again.
[19:04:50] <mhaberler> right
[19:05:16] <mhaberler> my jog-while-paused patch makes sure it returns before continuing though
[19:05:27] <Connor> it's almost like it needs to record the XYZ location. then abort.. let you jog around.. and stuff.. then before resume, go back to that recorded position
[19:06:24] <mhaberler> if the hal_manualtoolchange approach is ok, that should be doable
[19:08:21] <mhaberler> the approach could be: in the tc comp, poll emcstat and record abs position when aborting; on 'continue' add a MDI G53 g0 <lastpos…>
[19:09:29] <JT-Shop> so long as nothing is in the way your ok
[19:10:34] <mhaberler> ahem, yes..
[19:11:37] <Connor> okay, your patch is this one the manual-toolchange-with-tool-length-switch ?
[19:11:56] <mhaberler> that is in master ready to go and actually being used
[19:12:15] <Connor> explain ?
[19:12:17] <mhaberler> the 'patch' (not merged) is
http://git.mah.priv.at/gitweb/emc2-dev.git/shortlog/refs/heads/jog-while-paused-preview1
[19:12:54] <mhaberler> supported feature? just build a sim config off master, and run the example ini in there
[19:14:36] <Connor> Well, the fact that it's under sim is confusing me for one. And for two, I don't understand what your saying config off master. I have a custom config for my machine already.. so.. I'm just trying to figure out what I need to do to add this in.
[19:15:50] <mhaberler> sorry. you need 2.6-pre - either the buildbot packages, or build by pulling the master branch from git
[19:15:58] <Connor> I think I'm running 2.5.2 or so.
[19:16:33] <mhaberler> the remap code is not in there
[19:17:43] <andypugh> I don't know of anything that is worse in 2.6 at the moment
[19:17:43] <Connor> yea, I'm just now figuring that out..
[19:17:45] <mhaberler> which is the prerequisite for manual-toolchange-with-tool-length-switch etc
[19:18:04] <Connor> andypugh: You mean that's broken vs 2.5.2 ?
[19:18:17] <andypugh> Yes.
[19:18:18] <mhaberler> thats broken in 2.6 but not in 2.5
[19:19:41] <mhaberler> even the accidental features gene insists on having now work reproducibly ;-)
[19:20:00] <Connor> okay, so the 2.6 has everything 2.5 has and working okay, and maybe some new stuff that isn't done, or that's possibly broke, or is working
[19:20:18] <Connor> I don't want to break anything. :)
[19:20:42] <mhaberler> I am not aware on any major issue in 2.6; I use it mostly
[19:22:13] <Connor> I may just hold off.. It's just something I'm wanting.. no big hurry for it..
[19:23:24] <andypugh> Yes, me too.
[19:23:52] <Connor> and, hopefully, by the time it makes it in, I want need it anymore. :)
[19:24:08] <Connor> I'll have TTS and a Power Drawbar..
[19:28:23] <tjb1> Anyone order rack gear from Moore Gear?
[19:28:48] <mhaberler> there go my testers ;)
[19:29:49] <Connor> mhaberler: I might be able to use it on my router vs my mill.. No way to do TTS on the router.. and it would need jog and touch off way more than the mill after I get the TTS stuff
[19:30:24] <mhaberler> TTS… stands for..?
[19:30:48] <Connor> Tormach Tooling System. Quick Change via drawbar
[19:32:45] <mhaberler> aja
[19:33:05] <andypugh> Connor: You can make your own drawbar. I did :-)
[19:33:42] <Connor> Well. I'm using a Bosh Colt router. I might do something different if I ever change out the spindle.
[19:35:52] <tjb1> this is interesting -

[19:50:12] <ReadError> pretty
[19:50:18] <ReadError> you need to get some different endmills :)
[19:50:29] <r00t4rd3d> i only got 2 of the same size atm
[19:50:38] <r00t4rd3d> but i can scale the image
[19:50:39] <ReadError> well i used the dremel ones for a bit
[19:50:46] <r00t4rd3d> some douche taught me how :)
[19:50:50] <ReadError> til i got my confidence up ;)
[19:51:22] <r00t4rd3d> my router ate through it like it was nothing
[19:51:34] <r00t4rd3d> i was suprised
[19:51:45] <ReadError> what kinda stuff you going to make?
[19:51:53] <JT-Shop> r00t4rd3d: cool
[19:52:01] <tjb1> Very nice r00t4rd3d
[19:53:21] <ReadError> now cut some rage faces!
[19:54:43] <r00t4rd3d> i turned it off and ran inside :)
[19:55:11] <ReadError> what i do is have a VM running my same config
[19:55:19] <ReadError> then i can like "test" cut stuff 1st
[19:56:59] <r00t4rd3d> i set it up and took the bit out and ran it once
[19:58:51] <ReadError> well i mean after you generate some new gcode
[19:59:00] <ReadError> just to make sure it runs good
[19:59:07] <ReadError> ive got to the point now i trust it though
[19:59:26] <tjb1> Hows your quad copter?

[20:00:10] <r00t4rd3d> do rotozip bits work?
[20:02:16] <ReadError> no idea
[20:02:21] <ReadError> but you can get the dremel ball end
[20:02:26] <ReadError> and the V shaped pretty cheap

[20:04:15] <ReadError> what mill is that Connor?
[20:04:25] <tjb1> G0704
[20:04:29] <Connor> Grizzly G0704
[20:04:33] <tjb1> Its on the first picture :P
[20:04:49] <Loetmichel> *tinker* ... wouldn't it be fun to construckt something the boss couldnt pay my missing sleep... its about 03:00 over here and i have to be @ the company at 08:00....
[20:05:25] <tjb1> Did you make those stepper covers Connor
[20:05:50] <Connor> Yup. Those are the ones I milled about two weeks ago.
[20:06:46] <tjb1> Thought I remembered seeing those
[20:08:25] <Connor> I was thinking of putting something else on the covers.. Like maybe BH0704 or WH0704 (My nick name initials, or my proper name initials.) I don't go by my proper name except in legal stuff..
[20:08:55] <tjb1> Guess your name is WIlliam and you go by Bill?
[20:09:09] <Connor> Correct, except Billy not Bill.
[20:09:45] <tjb1> How much was that chain if you dont mind
[20:10:00] <Connor> Tried to go by "Will" about 15 years ago.. but.. never got use to it. :)
[20:10:16] <Connor> That was left over E-Chain for my router... let me look.. That's been a while.
[20:14:05] <Connor> Having a hard time tracking it down.
[20:14:19] <Connor> I purchased it combined with some couplers in April of 2011
[20:14:55] <tjb1> Where did you get it from?
[20:15:09] <Connor> Ebay seller, direct (not via ebay)
[20:15:39] <tjb1> ah sketchy :)
[20:17:40] <Connor> http://www.ebay.com/sch/miss_my_car/m.html
[20:17:42] <Connor> Nahh..
[20:18:31] <tjb1> Can you buy like 2 40" and patch them together?
[20:18:45] <Connor> Wasn't that sketchy. I've done that with both the E-Chain and Couplers, and my Ballscrews, linear rails and my stppers all for my router.
[20:18:48] <Connor> Yes.
[20:19:41] <Connor> I think I got 25x38 R55 x 1meter length
[20:19:44] <Connor> x 2
[20:19:47] <tjb1> Thanks
[20:19:48] <Connor> 2 of them.
[20:19:52] <Connor> for my router.
[20:19:55] <tjb1> Ill price check when I am closer to being ready
[20:20:11] <jdh> I got some really small stuff
[20:20:21] <tjb1> Ill need somewhere around 16-17' of it
[20:20:26] <jdh> amn
[20:20:29] <jdh> or damn.
[20:20:39] <Connor> dang. For what size machine ?
[20:20:43] <tjb1> 4x8
[20:20:58] <tjb1> but its about 10ft long and 6ft wid
[20:21:00] <Connor> Check linearmotionbearing2008 ebayer too.
[20:21:26] <tjb1> I didnt want to have an exact or very close to 4x8 cutting area and then spend 3 hours trying to get the stock in that area
[20:21:26] <Connor> I only ordered from this China ebayer because they had the couplers I wanted too.
[20:21:51] <tjb1> Go big or go home :)
[20:22:16] <jdh> http://www.ebay.com/itm/110739289334
[20:22:19] <Connor> Also, didn't have the sizes on ebay I was looking for.. but I knew they had to have other sizes.
[20:22:46] <Connor> 10mmx10mm That's SMALL stuff.
[20:22:56] <tjb1> yeah
[20:23:03] <tjb1> Id only get one cable in that haha
[20:23:16] <Connor> I actually did ALLOT of research and found to true manufacture of the E-Chain and got the specifications from them..
[20:23:24] <jdh> you can fit one stepper wire and a limit switch wire easily
[20:24:07] <tjb1> The x axis chain will need to hold 3 home-limit wires
[20:24:14] <tjb1> and 4 axis wires
[20:25:06] <tjb1> 3/4"x3/4" should work
[20:25:09] <tjb1> but it would be tight
[20:27:42] <tjb1> here it is

[20:27:53] <Connor> Mine is .88" thick by 1.875" wide
[20:28:29] <jdh> it looks pre-sagged in the middle?
[20:29:52] <tjb1> Thats the water table
[20:33:09] <Connor> Hmm.. having hard time reconciling what I have with what I supposedly ordered.. size that is..
[20:33:12] <tjb1> Are Ahrens rack and pinion drives reversible?
[20:33:42] <jdh> Connor: maybe they used a chinese ruler from dealextreme to measure it.
[20:33:50] <Connor> No..
[20:34:02] <Connor> It's something with the ID vs the OD of the channel.
[20:34:20] <jdh> some of the ads quote inside, some out
[20:34:48] <Connor> I'm starting to think it was 18mm x 37mm ID
[20:35:00] <Connor> that's .7" x 1.45"
[20:35:08] <Connor> let me go check the ID.. brb
[20:40:02] <Connor> Of good grief. one The height is the OD, the width is the ID
[20:41:23] <tjb1> 18mm inside, 37mm outside?
[20:42:29] <Connor> No. It's marked as 18x37.. I think that's the ID
[20:42:39] <Loetmichel> sooo, next PSU casing for the company done... now i should go to bed, get at least 3 hrs sleep... ->

[20:45:22] <r00t4rd3d> I need to score some HDP
[20:45:26] <tjb1> Nice
[20:46:02] <Loetmichel> its not the first one
[20:46:19] <Loetmichel> but the company has no CNC. so i make the prototypes at home...
[20:46:55] <Loetmichel> and now the night is a BIT short... its 03:35 over here, at 07:00 the clock will ring...
[20:47:31] <Loetmichel> last week i made this, for an other scanner:
http://www.cyrom.org/palbum/main.php?g2_itemId=13367
[20:47:48] <Connor> tjb1: Okay. DJ18 which is their PN for 18x38x1000 R48 (R48 is the Radius). gives total height at the bend of 119mm
[20:48:08] <tjb1> What do you bend it with Loetmichel
[20:48:13] <Connor> tjb1: They sent me drawings if I can find it..
[20:48:16] <Loetmichel> had
[20:48:18] <Loetmichel> hand
[20:48:27] <tjb1> So making a U, its 119mm thick?
[20:48:38] <tjb1> You make some damn straight bends by hand :)
[20:48:49] <Loetmichel> i mill a V-slot about half the seet thickness at the bendings
[20:49:00] <Loetmichel> and then you can bend it by hand and accurately so
[20:49:23] <Loetmichel> ;-)
[20:49:59] <tjb1> Very nice
[20:50:23] <tjb1> Can you use a 5/16 bolt with extrusions in the t slots
[20:50:47] <Connor> tjb1: Correct
[20:51:01] <tjb1> Guessing its pretty tight
[20:51:23] <Connor> 4.68" tall
[20:52:45] <tjb1> Anyone use extrusions? :)
[20:52:55] <Connor> tjb1: For what?
[20:53:00] <Connor> I've used 80/20 for some stuff
[20:53:07] <tjb1> Anything, I need to know if you can get a 5/16 bolt in the t-slots
[20:53:12] <tjb1> It says the gap is .320
[20:53:23] <Connor> which brand ?
[20:53:37] <Connor> and which series ?
[20:53:50] <Connor> If it's 80/20 then it's either 10 or 15 series
[20:53:59] <Connor> 10 being 1" 15 being 1.5"
[20:54:27] <tjb1> Well its T-slots
[20:54:35] <tjb1> but all my extrusions are either 1530 or 3030
[20:54:43] <Connor> okay, that's 15 series.
[20:54:54] <Loetmichel> tjb1: like ma grandma said one: "a lazy man isnt dumb"
[20:55:14] <WillenCMD> does anyone think i could wire both outputs of the mesa 7i39 in parallel to achieve 50v at 10A or no here is a link <
http://www.mesanet.com>
[20:55:18] <jdh> why doesn't your company invest in some cnc hardware ?
[20:55:32] <tjb1> Ha, lazy man always finds the easiest way
[20:55:50] <Loetmichel> or another one: "As a worker you can be lazy. You can be Dumb. But both gets you caught!"
[20:56:07] <Loetmichel> jdh: it will
[20:56:09] <Loetmichel> soon
[20:56:26] <Connor> as I recall, you need to use T-Nuts.
[20:56:32] <Loetmichel> we just have got some big oders
[20:56:39] <tjb1> Yes but I am concerned with the bolt I can get through there
[20:56:41] <Connor> I've not tried 5/16 bolt in it.
[20:56:49] <Connor> to bolt together >
[20:56:50] <Connor> ?
[20:56:52] <Loetmichel> so we can pay for a bit of "workshop-upgrade"
[20:57:00] <Connor> or for clamping stuff ?
[20:57:16] <tjb1> To attach the CRS for the linear system
[20:57:40] <tjb1> I am going to make a jig with drill bushings so I dont have to do it on a cnc
[20:57:40] <Connor> CRS ?
[20:57:44] <tjb1> cold rolled steel
[20:58:01] <jdh> WillenCMD: my guess is... no. That's pretty much just a guess though.
[20:58:10] <Connor> Your going to use CRS for linear rails?
[20:58:22] <tjb1> Yeah, its the cncrouterpards setup
[20:58:41] <Connor> I wouldn't use CRS for that.
[20:58:52] <Connor> I would use polished rails..
[20:59:11] <tjb1> ?
[20:59:23] <tjb1> http://www.cncrouterparts.com/extended-linear-carriage-with-abec-7-bearings-p-35.html?cPath=21
[21:00:29] <r00t4rd3d> I used aluminum rails for mine
[21:00:40] <r00t4rd3d> easier to work with
[21:00:45] <r00t4rd3d> or drill
[21:00:45] <Connor> r00t4rd3d: Yours is much smaller too.
[21:00:56] <r00t4rd3d> my mom said it was average
[21:01:00] <Valen> lol
[21:01:10] <Valen> we are looking at rails for our new mill
[21:01:14] <tjb1> This is good
[21:01:14] <tjb1> haha
[21:01:17] <Valen> thinking of using linear profile rail
[21:01:29] <Valen> its not that expensive really
[21:01:41] <tjb1> Linear rails are $0.4 per mm
[21:01:44] <tjb1> Not gonna happen
[21:02:37] <Valen> the ones I was looking at were something like $60 a meter?
[21:02:47] <Valen> rated for 1.5 tonnes ;->
[21:03:03] <Loetmichel> the rails are relatively cheap
[21:03:06] <Connor> tjb1: How long do you need ?
[21:03:14] <Loetmichel> the sleds are the expensive part ;-)
[21:03:19] <tjb1> 10ft
[21:03:27] <Connor> total or per side ?
[21:04:11] <tjb1> per side
[21:04:28] <Connor> THK or supported rail.. but.. 10' per side is allot
[21:04:32] <Valen> HGR15R HG RAIL SIZE 15 $85.00 per meter
[21:04:33] <Valen> HGH15CA Z0C BLOCK HG 15 NARROW BLOCK $48.00 net each
[21:04:45] <Valen> HGR20R HG RAIL SIZE 20 $90.00 per meter
[21:04:45] <Valen> HGH20CA Z0C BLOCK HG 20 NARROW BLOCK $55.00 net each
[21:05:33] <tjb1> A lot of people use the CRS setup
[21:07:33] <Loetmichel> i dont like the cold rolled steel mehtod: not really straight, to much ball bearings per sled, to flexible and over-dertermined.
[21:08:43] <Loetmichel> a hardened and precision ground round supported rail and sleds with 6 or 8 ball bearings are much more straight, precise and not more expensive
[21:09:04] <Loetmichel> so, now i WILL go to bed... for three hours
[21:11:19] <Connor> http://stores.ebay.com/linearmotionbearings?_trksid=p4340.l2563
[21:11:47] <Connor> email those people and check on supported rail..
[21:12:38] <tjb1> its $74 for 14"
[21:13:33] <Connor> It's cheaper the more you get..
[21:14:53] <Connor> The other option is to look into linear motion stuff from 80/20 since your using 80/20.
[21:15:07] <Connor> Dinner Time.
[21:28:54] <uw> hi does anybody know of any routines to create a moon surface finish on a piece or area?

[21:45:22] <r00t-Shed> anyone good with pycam?
[21:46:13] <ReadError> cuttin
[21:46:14] <ReadError> whats up
[21:46:42] <r00t-Shed> how i open the axis.ngc in pycam?
[21:46:56] <r00t-Shed> or do i have to export it from lincnc?
[21:47:02] <ReadError> ya
[21:47:08] <ReadError> generate and export visible
[21:47:12] <ReadError> oh wait
[21:47:14] <ReadError> nm
[21:47:17] <ReadError> u going backwards
[21:47:25] <ReadError> yea might be able to open the ngc
[21:47:28] <ReadError> never done it that way
[21:47:44] <r00t-Shed> it wont open in pycam
[21:49:15] <ReadError> use an image
[21:49:30] <ReadError> i dont know if you can go from gcode -> image
[21:50:50] <r00t-Shed> can i make the LinuxCNC example bigger in the program itself?
[22:32:03] <r00t-Shed> 1/4 inch is .0825?
[22:32:40] <r00t-Shed> nvm
[22:34:41] <r00t-Shed> so Filtering takes forever....
[22:34:56] <tjb1> 1/4 inch is .250
[22:35:06] <r00t-Shed> yeah
[22:35:22] <r00t-Shed> i found an online converter :)
[22:35:36] <tjb1> Ah a metric person :)
[22:35:42] <r00t-Shed> nope
[22:35:51] <tjb1> ?
[22:36:08] <r00t-Shed> i really wanted to know 1/8 but i typo
[22:36:13] <tjb1> .125 :P
[22:36:13] <roycroft> 1/4 inch is actually 0.250" :P
[22:36:59] * roycroft had the leading zero bit drummed into his head so much when he was first studying science that he is incapable of omitting it, even if he tried to do so intentionally
[22:37:21] <tjb1> What size is a 13mm nut?

[23:56:43] <samkan> Do i need to use Z axis If i wants to use engraving?
[23:57:30] <samkan> I want to do engraving using inkscape gcode tools, it generates gcode file with Z value, do i will need support of Z axis?
