[02:06:32] <ReadError> is one of the devs
[02:06:33] <r00t4rd3d> a good one
[02:06:41] <ReadError> well that place

[02:07:40] <r00t4rd3d> they expensive though but i like theirs better then k2's
[02:07:55] <ReadError> how much is the price difference?
[02:09:05] <r00t4rd3d> probotix with shipping will probably be 10 bucks more
[02:09:19] <r00t4rd3d> 69 shipped for a bosch colt mount from k2
[02:09:22] <ReadError> ironically
[02:09:31] <ReadError> if you had a router table you could make your own ;)
[02:10:03] <jdhNC> or a hole saw, or jig saw
[02:10:07] <ReadError> ya
[02:10:23] <ReadError> jig saws rock
[02:10:39] <tjb1> Jymmm: What enclosure is that
[02:10:42] <r00t4rd3d> i have a jig saw and a scroll saw
[02:10:48] <r00t4rd3d> and a hole saw set
[02:10:55] <tjb1> plasma cutter ;)
[02:10:59] <jdhNC> or a U bracket
[02:11:04] <r00t4rd3d> band saw, table saw, drill press
[02:11:17] <ReadError> you cant make one r00t4rd3d ?
[02:11:27] <r00t4rd3d> i want an aluminum one
[02:11:47] <ReadError> ah
[02:11:49] <jdhNC> hey, buy one from K2
[02:12:05] <r00t4rd3d> i might
[02:13:31] <r00t4rd3d> they are kinda pushy though
[02:14:08] <r00t4rd3d> i used their contact us button and they called me and emailed me twice
[02:14:20] <r00t4rd3d> and i only asked when a mount was going to be back in stock
[02:15:27] <r00t4rd3d> the girl asked me what i thought about the mount and i told her i thought it was expensive.
[02:15:31] <ReadError> chinamen?
[02:16:21] <r00t4rd3d> they are in california i believe but she sounded mexicanish
[02:16:28] <jdhNC> it's expensive if you just look at material time
[02:16:33] <jdhNC> s/time/cost/
[02:18:58] <r00t4rd3d> hard to justify a 70 dollar mount for a 83 dollar router

[11:35:07] <jthornton> The U.K. has one of Europe's fattest populations: more than 60% of adults and one third of children aged 10-11 are overweight or obese, roughly similar to U.S. statistics.
[11:37:08] <jthornton> yesterday when I took the MIL to PT there was a 350 pound woman leaning against the "No Smoking within 50' of the entrance" sign smoking a cigarette...
[11:37:38] <jthornton> we seem to have a large number of slackers that eat and smoke all day and have babies on our dime around here
[11:40:04] <archivist> but, on a happier note, I thought the over arm/bar on the horizontal would be impossible to get out without a press, lump hammer and a bit of brass a few taps and it moved
[11:40:47] <archivist> then was able to rotate it to de rust and eventually get it free

[11:42:46] <jthornton> so it is cutting torch time this morning
[11:43:39] <archivist> I expected a much harder fight with the rust, but the part actually in the frame was rust free basicly
[11:44:45] <jthornton> nice
[11:51:34] <jthornton> archivist, do you have a photo of what your working on?
[11:52:49] <archivist> that is the mill when at work http://www.archivist.info/cnc/works2008/P1010225.JPG
[11:53:34] <archivist> I cannot stand that far back in the garage to take a similar one now
[11:53:51] <jthornton> lol I understand
[11:55:01] <jthornton> do you move the over arm in and out as needed for the job, I've never ran a mill like that...
[11:56:38] <archivist> if only used as a horizontal, no need to move it, but I want to use as a vertical on the side and as a horizontal boring machine
[11:58:14] <archivist> I made up the boring head adapter on Monday (neighbour wants a bit of his lorry boring)

[14:32:41] <Tom_itx> JT-Shop did you get your plasma figured out?
[14:33:49] <JT-Shop> yes
[14:34:29] <Tom_itx> what was the issue?
[14:35:01] -!- Thetawaves has quit [Quit: This computer has gone to sleep]
[14:38:02] <JT-Shop> there was two problems, if you don't have a file loaded you can't call a subroutine from the MDI and this caused problem #2 trying to reload LinuxCNC with 4Gb of memory and the lan cable plugged in ubuntu thought it better to have a different kernel
[14:38:26] <Tom_itx> how nice of it
[14:39:37] <JT-Shop> better to know the exact cause than wonder why something won't work as expected
[14:39:48] * JT-Shop goes to walk the dog
[14:40:05] <Tom_itx> so in order for any sub to work with MDI you must first load some random gcode file?
[14:44:48] <sendoushi> what is a coupling for?
[14:45:08] <Tom_itx> to join 2 shafts
[14:45:22] <sendoushi> and why is that needed on a cnc?
[14:45:24] <jdhNC> or just for recreational purposes.

[14:46:49] <sendoushi> no money for such a thing eheeh
[14:46:58] <sendoushi> i would buy a kit on the 400 500$

[14:56:00] <jdhNC> I ended up sanding/scotchbriting the stepper covers. Even after 3 coats, it still wasn't smooth. I lightly sprayed after sanding and it seemed to coat evenly this time.
[14:57:07] <sendoushi> http://www.damencnc.com/en/components/mechanical-parts/trapezium-nuts---spindles is this what i'm looking for? :P:P
[14:57:51] <jdhNC> depends, what are you looking for?
[14:58:02] <sendoushi> for the acme precision rod
[14:58:04] <sendoushi> (i think)
[14:58:41] <jdhNC> probably fine. not sure how 'precision' it is. It might not really be acme, but that doesn't matter.
[14:58:56] <sendoushi> can't find acme in europe so...
[14:59:11] <jdhNC> doesn't matter
[14:59:35] <jdhNC> acme is sometimes a generic term anyway.
[14:59:35] <sendoushi> is the linear bearing block the "thing" that goes with the rod?
[14:59:55] <sendoushi> i just find expensive stuff nhieee
[15:00:01] <JT-Shop> Tom_itx: yes it can be a one line file with m2 in it...
[15:00:08] <Tom_itx> heh
[15:00:42] <Tom_itx> oh, is there a way to change the default file loaded so the logo file doesn't always come up?
[15:00:42] <sendoushi> the mechanics of this really scaries me
[15:00:44] <jdhNC> you need a bearing block of some sort at the driven end at least. Not a linear bearing block though.

[15:02:59] <sendoushi> inside EU there isn't customs
[15:03:03] <JT-Shop> that's part of the puzzle
[15:03:27] <sendoushi> the problem is that the puzzle can become expensive if i don't know what i want eheh
[15:03:33] <sendoushi> or where to go
[15:03:34] <jdhNC> but there is VAT?
[15:03:42] <JT-Shop> if it puzzles you then scratch built might not be a viable solution
[15:03:46] <sendoushi> most of the times there is vat
[15:05:20] <Connor> jdhNC: You took it paint all off and sanded and sprayed again ? with light coat ?
[15:05:48] <jdhNC> connor: no, I just took the top off the existing paint (and smoothed out the runs)
[15:06:00] <Connor> ok.
[15:06:19] <Connor> what about the sides ? That's what kept giving me the strange effect...

[15:13:26] <jdhNC> leadscrew is usually cheaper and less precise
[15:13:36] <tjb1> Depends on your wallet :)
[15:14:13] <sendoushi> my wallet has flies
[15:14:13] <sendoushi> :D
[15:14:22] <sendoushi> then leadscrew is the way :D
[15:14:51] <Connor> how big you making?
[15:15:00] <Connor> you can use belt/chain drive too..
[15:15:06] <sendoushi> guitar big
[15:15:20] <Connor> Oh yea, that's right. So not super large.
[15:15:28] <sendoushi> no...
[15:15:35] <jdhNC> acoustic or electric?
[15:15:45] <sendoushi> 21.6'' * 18.1'' * 4'' i think this is the max
[15:15:54] <sendoushi> electric
[15:15:57] <tjb1> Its that time of the year for Wikipedia....
[15:16:01] <sendoushi> and semi-acoustic
[15:16:13] <Connor> sendoushi: Moving Gantry or moving table ?
[15:16:24] <sendoushi> thinking about moving gantry but... you tell me :$
[15:16:25] <Connor> mine was moving gantry.
[15:17:02] <sendoushi> moving table needs space right?
[15:17:08] <Connor> About the same either way. You still need the same parts. In some cases moving table can cost more $$ because need more travel of the table to reach desired goal.
[15:17:10] <sendoushi> and there is not much of a difference right?
[15:17:26] <sendoushi> moving gantry is the way to go
[15:17:33] <jdhNC> now do you make the neck?
[15:17:52] <sendoushi> jdhNC: as a beginner no but i'll want to make it
[15:17:58] * Tom_itx looks puzzled at the puzzle
[15:18:05] <sendoushi> but maybe when i do the neck im ready to upgrade my cnc
[15:18:19] <Connor> Some people like moving table over moving gantry because they want the gantry to be more stable or rigid. Example, people using it to make PCB need way more accuracy.
[15:18:39] <sendoushi> Connor: i dont need more precision than 1mm
[15:18:44] <sendoushi> i can always hand-finish
[15:18:50] <Connor> moving gantry is good then.
[15:19:22] <sendoushi> of course that if i have more precision... the better but for now...
[15:19:23] <jdhNC> strat or tele body?
[15:19:41] <sendoushi> more of a tele guy but i'll make ES-335 also
[15:19:49] <sendoushi> the first one will be a tele
[15:23:12] <sendoushi> by the way i have access to a CNC (my brother's metal factory has one)
[15:23:33] <sendoushi> so... it's an industrial one bought to mill metal

[15:38:49] <sendoushi> IchGuckLive: sorry the ignorance but... what are those for?
[15:38:57] <sendoushi> IchGuckLive: the pins...
[15:39:08] <Connor> sendoushi: You might be able to get the mechanics for $500.00, but, your still going to need the controller and steppers..
[15:39:14] <tjb1> Yes JT, but the divder runs to ground…instead of running to ground would I run it back to the other pin?
[15:39:20] <IchGuckLive> how do you expect to move the Axes around
[15:39:26] <sendoushi> 500$ for the mechanics? can't i get it for like 300$ ?
[15:39:42] <IchGuckLive> around 200USD for all
[15:39:53] <IchGuckLive> is a good price
[15:40:00] <JT-Shop> sure but remember you want to make things too
[15:40:01] <sendoushi> IchGuckLive: from what i've seen motor -> coupling -> leadscrew -> block -> moves! isn't this right?
[15:40:13] <Tom_itx> JT-Shop, so if no OPEN_FILE is specified it defaults to the logo?
[15:40:20] <JT-Shop> yep
[15:41:12] <JT-Shop> sendoushi: http://buildyourcnc.com/step1.aspx
[15:41:17] <Connor> I spent $467.00 USD on the rails, rail blocks, the ballscrews, ballscrew mounts, and couplers..
[15:41:33] <Connor> that total included the 99 shipping.
[15:41:47] <sendoushi> JT-Shop: i was thinking about that design
[15:41:51] <Tom_itx> JT-Shop, does it use PROGRAM_PREFIX or do i need to specify the full path?
[15:42:02] <sendoushi> JT-Shop: to make it a little cheaper
[15:42:07] <tjb1> JT-Shop: would I run one wire from one pin through both resistors than back to the other pin?
[15:42:11] <JT-Shop> I'm not saying it is great but it seems to fit
[15:42:22] <sendoushi> i know
[15:42:42] <JT-Shop> tjb1: IIRC I put them resistors end to end
[15:42:54] <IchGuckLive> sendoushi: yes and here is our chinese counterpart frend http://www.auctiva.com/stores/viewstore2.aspx?id=1306389&styleid=72
[15:43:01] <JT-Shop> Tom_itx: what is it?
[15:43:02] <Connor> I later purchased 3 more ballscrews/nuts for 190usd.
[15:43:11] <IchGuckLive> Ballscrews 1,5m for 70USD
[15:43:13] <sendoushi> IchGuckLive: ?
[15:43:19] <Tom_itx> PROGRAM_PREFIX = ~/emc2/nc_files - The default location for g-code files and the location for user-defined M-codes. This location is searched for the file name before the subroutine path and user M path if specified in the [RS274NGC]
[15:43:20] <tjb1> JT-Shop: I know that, you pull the new voltage from in between…im not sure how to do it through as the divider should go to ground but I cant measure the voltage between this pin and the machine ground
[15:43:34] <Tom_itx> or do i need to specify that in the OPEN_FILE var as well?
[15:43:41] <Tom_itx> i'll just test it and see...
[15:43:44] <JT-Shop> tjb1: google voltage divider circuit
[15:43:53] <sendoushi> IchGuckLive: ballscrews seems kind of expensive... isnt leadscrew better for me?
[15:44:15] <IchGuckLive> sendoushi: querry ?
[15:44:19] <sendoushi> querry?
[15:44:23] <JT-Shop> Tom_itx: ok, the OPEN_FILE can be any path AFAIK
[15:44:42] <tjb1> JT-Shop: I already know how it works :) you take the voltage + run it through two resistors then go to ground and you pull the new voltage from in between the two resistors
[15:44:59] <IchGuckLive> sendoushi: ther shoudt be a new open folder in your irc frame
[15:45:00] <JT-Shop> then you know more than me :)
[15:45:40] <Tom_itx> that's called a voltage divider
[15:45:50] <tjb1> Im just not sure how to hook up the divder with the plasma cutter as you measure the voltage between the two pins and not a ground
[15:46:21] <JT-Shop> on the THCAD card I just put the resistors in line with the +
[15:46:24] <Tom_itx> +V---DIVIDED V----GND
[15:46:48] <Tom_itx> +V-/\/\--DIVIDED V--/\/\--GND
[15:47:09] <tjb1> I guess im not explaining this good enough :P
[15:48:09] <JT-Shop> or I don't have a clue what your talking about
[15:48:14] <tjb1> The plasma cutter has two pins for the shield voltage, neither is a ground…so would it be Pin 1 - /\/\ -- Divided V -- /\/\ - Pin 2
[15:48:14] <Tom_itx> if i had a plasma it may make more sense
[15:48:45] <JT-Shop> tjb1: what kind of plasma cutter is it?
[15:48:48] <Tom_itx> or what jt said
[15:48:50] <Tom_itx> :)
[15:48:59] <tjb1> hypertherm powermax 45
[15:49:25] <JT-Shop> does it have two pins on the circuit board for tip voltage?
[15:49:37] <tjb1> Well it has the two pins in the CPC port
[15:50:03] <JT-Shop> different than the 1250 then
[15:50:06] <tjb1> Its already 50:1 with a max of 7v and I need to bring it down to a max of 5v thus the need for this voltage divider
[15:50:44] <JT-Shop> mine is a 0-300vdc signal
[15:51:20] <JT-Shop> all I know is what pcw told me to do on mine
[15:51:28] <tjb1> Well I need to go to work, I will confuse you all later :)
[15:51:36] <Tom_itx> what voltage is across the 2 pins?
[15:51:40] <JT-Shop> ok, I look forward to it
[15:51:56] <tjb1> Maybe I will make a picture to better illustrate my confusion
[15:52:04] <Tom_itx> full color
[15:52:10] <JT-Shop> ok
[15:52:16] <tjb1> Tom_itx: the voltage acrtoss the pins is the arc voltage
[15:52:28] <Tom_itx> but you need less of it?
[15:52:40] <tjb1> Well the 7v will hurt my micro
[15:53:16] <Tom_itx> is one of them ground?
[15:53:17] <tjb1> I need to get it down to 0v-5v so I can make the THC
[15:53:21] <Tom_itx> and one +7v?
[15:53:44] <tjb1> I tested them against the ground in the CPC and neither checked out

[15:54:00] <tjb1> So either the CPC ground is a different one or im completely stupid :)
[15:54:05] <Tom_itx> is the CPC grounded to the same board as the pins?
[15:54:22] <tjb1> Not a clue
[15:54:22] <Tom_itx> all grounds should tie together under normal circumstances
[15:54:39] <tjb1> I tested both pins against the ground in there with the continuity check
[15:54:54] <Tom_itx> test each voltage to gnd
[15:55:15] <tjb1> Pin 1 - Pin 2 = shield voltage
[15:55:25] <tjb1> Pin 1 - ground = nothing and pin 2 - ground = nothing
[15:55:49] <Tom_itx> then they must not share a common ground
[15:56:06] <tjb1> Well I will see what I can come up with for tonight
[15:56:10] <tjb1> I have the service manual
[15:56:48] <Tom_itx> it may be isolated for a reason. i have no clue about that
[15:57:12] <JT-Shop> mine is just two pins and no connection to ground
[15:57:29] <JT-Shop> IIRC
[16:00:47] <tjb1> Thats what I think mine is JT-Shop and thats why im not sure how to hook up a voltage divider because it requires the ground
[16:00:59] <tjb1> Good bye all, be back in about 5-6 hours

[16:05:02] <archivist> JT-Shop, more rigid than most designs we see
[16:05:57] <JT-Shop> yea, based on Loetmichel's design which I like very much
[16:06:32] <JT-Shop> so far only one part needs to be machined
[16:06:46] <jdhNC> the bearing mount?
[16:08:04] <JT-Shop> yea
[16:08:40] <jdhNC> 16 skate bearings for $9.98 shipped
[16:08:40] <Tom_itx> i like it but what about a solid radius'd bearing on the top and a springloaded radius'd bearing on the top?
[16:09:23] <Tom_itx> you are going for the cheap?
[16:09:52] <mozmck> JT-Shop: how will you ensure the supports are exact enough to make sure the rods are straight?
[16:09:57] <Tom_itx> then the bearings could mount to the outter plate
[16:11:01] <archivist> mozmck, clamp all 5 parts together and drill at the same time
[16:11:02] <JT-Shop> if your equipment challenged then make a drill guide and drill the holes before cutting out the missing parts
[16:11:07] <jdhNC> if you mount them top and bottom, the rails have no support
[16:11:31] <mozmck> that makes sense. neat design.
[16:11:50] <JT-Shop> Tom_itx: I'm going for cost effective and rigid enough to actually work
[16:12:08] <jdhNC> JT: work for plastic/wood or metal?
[16:12:12] <JT-Shop> mozmck: not my idea, I stole from Loetmichel
[16:12:28] <Tom_itx> err swap those, put the loaded bearing on the bottom
[16:12:42] <JT-Shop> jdhNC: dunno if it would be stout enough for more than engraving metal
[16:12:43] <Tom_itx> it should work fine, except the radiused bearings may cost more
[16:13:30] <JT-Shop> yea, R3 bearings are cheap on flea bay
[16:13:40] <Tom_itx> and screwing them to the plate would be less machining
[16:13:54] <Tom_itx> figuring out the spring loaded flange may take some thought
[16:14:04] <JT-Shop> I'm not following your thoughts
[16:14:37] <Tom_itx> instead of the 2 inner plates, bolt the bearings there instead to the outter plate
[16:14:44] <Tom_itx> and spring load the bottom set
[16:14:59] <jdhNC> that doesn't give you any side-to-side rigidity
[16:15:03] <Tom_itx> it would require a spacer

[16:15:43] <jdhNC> 36C
[16:15:44] <uw> accident sorry
[16:16:47] <JT-Shop> Tom_itx: the bearings are on a 45 degree angle, how would you bolt them to the outer plate?
[16:17:14] <Tom_itx> different bearings with a radius'd outter race
[16:17:50] <Tom_itx> but they would likely cost alot more so it may not be an option
[16:18:14] <jdhNC> 45 gives support in both axes
[16:18:33] <JT-Shop> http://imagebin.org/216517
[16:18:51] <Tom_itx> yeah i know, rue made one
[16:18:57] <Tom_itx> similar
[16:19:17] <Tom_itx> how do you take up slack?
[16:19:22] <JT-Shop> Tom_itx: I've seen V bearings but not with a radius and yea they would be expensive
[16:19:25] <archivist> if the holder is eccentric one can preload a bit
[16:20:16] <JT-Shop> Tom_itx: my guess is with shim stock on top of the shafts
[16:20:16] <jdhNC> cam'ed shoulder bolt?
[16:20:24] <archivist> yup
[16:21:32] <archivist> or something similar an eccentric sleeve and normal cap head screws
[16:23:05] <jdhNC> the preload will be relative to the bearing in plane with it?
[16:24:41] <archivist> one of the low cost suppliers has the right part for that bearing adjustment

[16:44:39] <Jymmm> JT-Shop: Gotcha. They are close enough that I could drive over if needed.
[16:44:44] <JT-Shop> archivist: yea, that would be a two setup part on a lathe from hex stock
[16:45:31] <archivist> JT-Shop, bottom would not need eccentric bushes, just the top
[16:47:11] <JT-Shop> really only need one per block I think

[16:48:12] <Jymmm> JT-Shop: In production line machinery; are the guides, rails, wheels, etc all custom made to order usually (like corkscrew for wine bottles as example), or can you buy them in modules/components to sorta "erector set" a complete system?
[16:48:15] <archivist> JT-Shop, need two so you can set it parallel to other end of the block and to get the plate right angle to frame
[16:50:06] <JT-Shop> Jymmm: most of the time those are off the shelf parts... see mcmaster carr

[17:17:11] <IchGuckLive> Problem i changed from EMC to Linuxcnc
[17:17:32] <JT-Shop> do you mean when you run from a RIP or installed?
[17:17:35] <IchGuckLive> damm now it graps files from "/usr" out of soomewhere EMC or linuxcnc
[17:17:50] <JT-Shop> are you trying to run a RIP?
[17:17:57] <IchGuckLive> i pulled the ppa master-rt lucid 32
[17:18:12] <IchGuckLive> there is a RIP also
[17:18:30] <IchGuckLive> and the system setup das been by LIveCD
[17:19:04] <IchGuckLive> i discoverd the Rtpi.conf war using linuxcnc
[17:19:41] <IchGuckLive> but as i stardet up from the main menue the Axis Foam is correct
[17:19:53] <JT-Shop> are you trying to run a Run In Place IE something you downloaded from git?
[17:20:13] <IchGuckLive> if i put the mashine files into the linuxcnc config folder it is not showing me the correct output
[17:20:32] <IchGuckLive> no i will move to master-rt
[17:20:45] <IchGuckLive> as now all the patches are in there
[17:20:48] <JT-Shop> O
[17:21:03] <IchGuckLive> also the Pncconf 5i25+7i77 is in there
[17:21:04] <JT-Shop> I'm really confused as to your question now
[17:21:28] <IchGuckLive> as here 2
[17:21:39] <JT-Shop> ok were on the same page then
[17:21:54] <JT-Shop> did you download a deb and install that?
[17:22:03] <IchGuckLive> if i go for the axis-foam in the sim all is correct in
[17:22:17] <IchGuckLive> no i got the buildbot ppa
[17:22:21] <IchGuckLive> no deb
[17:22:39] <IchGuckLive> synaptic pulled that and removed emc2.4
[17:22:42] <JT-Shop> so you have the files located somewhere in your home directory?
[17:22:57] <IchGuckLive> but the files are still all in "/usr/share"
[17:23:26] <JT-Shop> sure
[17:23:28] <IchGuckLive> what files config and nc_files are under linuxcnc folder now
[17:23:43] <IchGuckLive> can i delete all this emc stuff there
[17:24:37] <JT-Shop> best to uninstall 2.4 if you have 2.5 or master installed with the synaptic package manager
[17:25:13] <IchGuckLive> it has been unistalled by master-rt
[17:25:23] <IchGuckLive> but not revoved the files
[17:25:42] <IchGuckLive> so i guess the path wil find emc in usr first then linuxcnc
[17:25:57] <IchGuckLive> BUT why then axis-foam is showing correctly
[17:26:14] <IchGuckLive> and the real mashine config in the same folder doesend
[17:26:32] <IchGuckLive> is there a link inside the Hal or costomhal
[17:26:34] <JT-Shop> my guess is it only replace some files and not deleted 2.4
[17:26:45] <IchGuckLive> inside the ini the path has bean set to linuxcnc
[17:26:55] <JT-Shop> just depends on how you set the environment
[17:27:04] <IchGuckLive> 2.4 is emc 2.6 is linuxcnc
[17:27:22] <IchGuckLive> is the envirerment to be set inside ini ?
[17:27:40] <IchGuckLive> or hal
[17:27:48] <JT-Shop> nope, if you type linuxcnc from a prompt you get what ever is installed
[17:28:18] <IchGuckLive> this is what confuses me
[17:28:23] <roycroft> hey folks
[17:28:24] <JT-Shop> if you have a RIP and type in . ./scripts/ripenvironment you get the version that is there

[17:28:58] <roycroft> i attempted installing it a while back in a linuxcnc/ubuntu 10.04 environment, but there were significant depenency issues
[17:29:09] <IchGuckLive> roycroft: tommorow new relese im sitting on it
[17:29:16] <roycroft> while i have 35 years of unix/bsd experience, i've virtually no linux experience
[17:29:44] <roycroft> i wonder if there's a fairly easy path to installing it - i attempted what was documented for installing on 10.04 but still had issues
[17:29:59] <JT-Shop> IchGuckLive: how exactly did you install 2.6?
[17:30:05] <roycroft> it's been a while, and i did not document the problems - i just deleted that vm, but it's time to give it another go
[17:30:08] -!- phantoxe has quit []
[17:30:15] <roycroft> i will likely wait until next week, ichgucklive
[17:30:17] <IchGuckLive> JT-Shop: the case is if i go for prompt linuxcnc -> sim axis-foam correct
[17:30:19] <roycroft> thanks for the heads-up though
[17:30:27] * roycroft has a busy weekend ahead of him
[17:30:54] <IchGuckLive> if i go prompt linuxcnc-> my mahine doesent show correct same file
[17:31:06] <JT-Shop> IchGuckLive: from the Applications > CNC > Linuxcnc > sim > axis-foam
[17:31:29] <JT-Shop> ?
[17:31:29] <IchGuckLive> JT-Shop: http://buildbot.linuxcnc.org/ This warks also correct
[17:32:02] <IchGuckLive> so i thought there is somthing inside the ini or a other file that directs towards emc
[17:32:25] <IchGuckLive> JT-Shop: works correct that way 2
[17:32:34] -!- psha [psha!~psha@] has joined #linuxcnc
[17:32:37] <JT-Shop> nope, it just depends on how your environment is set
[17:32:55] -!- Guthur [Guthur!~user@] has joined #linuxcnc
[17:32:56] <IchGuckLive> where is the envirerment set
[17:33:23] <IchGuckLive> in the real install from synaptic via "deb http://buildbot.linuxcnc.org/ lucid master-rt
[17:33:27] <JT-Shop> if you have a RIP you can set the environment as I said before
[17:33:46] <JT-Shop> otherwise you get the installed version
[17:34:06] <IchGuckLive> i know that this si started by a script but not used since days its just on the system for more devels stuff
[17:34:48] <IchGuckLive> i will now search the "/usr" for emc files and kill them
[17:35:01] <JT-Shop> ok, have fun
[17:35:05] <IchGuckLive> maybe folders also in share
[17:35:26] <IchGuckLive> if i go with synaptic it will kill also the pythons or
[17:35:36] <JT-Shop> I'd just go see if the synaptic packager manager still says it is there and uninstall it
[17:35:48] <IchGuckLive> JT-Shop: ? synaptic komplete remove better ?
[17:36:02] <IchGuckLive> no its not there
[17:36:03] <JT-Shop> and make sure you remove emc from software sorces
[17:36:17] <JT-Shop> sources in synaptic
[17:36:29] <pcw_home> Kill the Pythons???
[17:36:31] <IchGuckLive> its in the 3dr pary removed from packets
[17:37:11] <IchGuckLive> its a hell of a miss with that
[17:37:43] <IchGuckLive> sim runs perfect and the mashine does not show as expected
[17:37:55] <IchGuckLive> i will get it
[17:38:03] * JT-Shop gets the torch out to melt some pythons
[17:38:14] <IchGuckLive> i guess there is also some so files around
[17:38:53] <IchGuckLive> "so" as i did a make to see the linuxcnc.so compiling
[17:39:21] <IchGuckLive> there is a emc.so or emcmodule.so
[17:39:35] <IchGuckLive> i will keep on this
[17:39:48] <roycroft> so is it heekscad or heekscnc that will have a new release tomorrow?
[17:40:11] <IchGuckLive> both
[17:40:15] <roycroft> ok, cool
[17:40:23] <syyl> maybe it will be usable then...
[17:40:32] <IchGuckLive> soon as the compiling on a fresh 10.04 runs
[17:40:35] * roycroft pushes the whole project onto the back burner for a few days
[17:41:04] <IchGuckLive> roycroft: Dan has to mill 15.000 parts
[17:41:10] <IchGuckLive> so less time
[17:41:29] <roycroft> i'm very patient
[17:41:37] <roycroft> and i have plenty of other projects to work on
[17:42:03] <IchGuckLive> librecad 2.0.1 is also outv
[17:42:25] <roycroft> hopefully there will be updated installation documentation when the new release comes out
[17:42:32] <IchGuckLive> now better then the Q-cad that is selled for 600USD
[17:42:48] <roycroft> i found qcad tolerable
[17:42:54] <roycroft> but i wasn't overly impressed with it
[17:43:08] <IchGuckLive> Autocad users are
[17:43:09] <roycroft> most of my cad experience is with autocad, although i've been toying with solidworks of late
[17:43:29] <IchGuckLive> im working with PROE
[17:43:30] <roycroft> autocad is not the best fit for 3d modelling
[17:43:46] <IchGuckLive> solid is still NURBS
[17:44:01] <roycroft> inventor is the autodesk product that does that well, but i have found, so far, that solidworks is a lot more intuitive than inventor, for me, at least
[17:44:06] <IchGuckLive> real 3D not many on the marked
[17:44:40] <IchGuckLive> solid has a nice DXF to 3D aplication
[17:45:03] <IchGuckLive> but in the Universyty al are loosing in the game to be direct or via tool construction
[17:45:23] <roycroft> my primary interest right now is in a decent cam application
[17:46:04] <IchGuckLive> Mastercam or Hypermill
[17:46:12] <roycroft> i've never used heekscam, so i don't know how that would work out
[17:46:20] <roycroft> yes, those might be options
[17:46:28] <IchGuckLive> universyty install for 60USD gives you 2years of max performance
[17:46:31] <roycroft> i'm looking at freely-available stuff rigth at the moment
[17:46:36] <syyl> it will work out like a pain in the butt ;)
[17:46:44] <syyl> its not realy usable
[17:46:52] <roycroft> how do you know?
[17:46:56] <roycroft> a new release is coming out tomorrow :)
[17:47:09] <syyl> ok, that was for the last release ;)
[17:47:14] <syyl> but i have no high hopes
[17:47:21] * roycroft will be hand-coding gcode for a while anyway
[17:47:25] <Jymmm> JT-Shop: Do you have any idea on how they are actually cutting the tubing??? http://www.youtube.com/watch?v=mw1L1L-_ypo
[17:47:25] <syyl> instead i would go for cambam
[17:47:31] <IchGuckLive> roycroft: dont expect to mutch only the glue cams are overritten
[17:47:36] <syyl> its pretty capable
[17:48:07] <syyl> magic, Jymmm
[17:48:20] <syyl> not a answer you were expecting, ha? ;)
[17:48:26] <roycroft> cambam only runs on windows
[17:48:30] <IchGuckLive> Jymm by roto knive
[17:48:31] <Jymmm> syyl: I gave up voodoo for lent =)
[17:48:36] <syyl> ;)
[17:48:37] <roycroft> not a disqualifier, but certainly a negative
[17:48:48] <syyl> its runs on linux
[17:48:49] <IchGuckLive> jym like lense blend
[17:48:53] <roycroft> oh?
[17:49:00] <Jymmm> IchGuckLive: like a tablesaw blade?
[17:49:04] <roycroft> i was just looking at the website and it talks about requiring windows with .net
[17:49:12] <IchGuckLive> no
[17:49:31] <Jymmm> IchGuckLive: I dont see the tube being deformed either
[17:49:37] <IchGuckLive> Jymmm: http://blog.ankimo.net/wp-content/uploads/2009/04/fotolia_11886163_s.jpg
[17:49:41] <syyl> i think its like a tube cutter
[17:49:45] <Tom_itx> JT-Shop what is your purpose for making the CNC drawings?
[17:49:50] <syyl> rotating around the pipe
[17:49:58] <Tom_itx> are you gonna make plans, make a kit...
[17:49:58] <IchGuckLive> about 24knives in the 360Deg
[17:49:58] <Jymmm> IchGuckLive: oh no way! I hope not.
[17:50:15] <JT-Shop> Tom_itx: ?
[17:50:28] <Tom_itx> your solidworks models you posted
[17:50:38] <Tom_itx> of the slide mechanism
[17:50:42] <IchGuckLive> its just hidding the tube and the X-force gets it off
[17:50:50] <JT-Shop> oh, dunno... if I make drawings they will be on my web site
[17:50:55] <roycroft> mastercam is definitely out of my current price range
[17:51:03] <IchGuckLive> Jymmm: there is also airflow inside the given tilt
[17:51:22] <IchGuckLive> roycroft: Student version 75USD
[17:51:32] <Jymmm> IchGuckLive: I was sorta thinking like a food processor blade
[17:51:47] <Tom_itx> JT-Shop, one concern i have (i know it's widely used) is that there is little contact surface between the outter bearing race and the round bar it rides on.
[17:51:57] <JT-Shop> Tom_itx: mainly Loetmichel's design got my interest
[17:52:05] <JT-Shop> yep
[17:52:07] <Tom_itx> yeah i've seen that design
[17:52:37] <Loetmichel> Tom_itx: the small contact isnt a problem
[17:52:43] <IchGuckLive> Jymmm: i make(made) molds for wirerchannel and we cut it the same way at 40m/min
[17:52:46] <JT-Shop> there you go
[17:52:51] <roycroft> yes, but i'm no longer a student
[17:52:58] <Jymmm> IchGuckLive: This is all perfect timing at about 1:40 http://www.youtube.com/watch?v=-MFD4RQ1aek&feature=related
[17:53:03] <roycroft> my use will eventually be commercial anyway
[17:53:15] <IchGuckLive> roycroft: but you know one
[17:53:21] <Jymmm> IchGuckLive: using the camera blade thing?
[17:53:33] <Loetmichel> the "kneading" of the bearing rings IS
[17:53:36] <roycroft> kids are too old to be students, grandkids too young
[17:53:44] * JT-Shop is off to town to get some burning glasses...
[17:53:56] <JT-Shop> Loetmichel: did you see the photo?
[17:54:05] <Jymmm> JT-Shop: for Burning Man?
[17:54:06] <IchGuckLive> Jymmm: extrusion
[17:54:23] <Loetmichel> lifetime of the 604 bearings on may machine is supposed to be about 50h
[17:54:40] <Loetmichel> JT-Shop: which one?
[17:54:42] <IchGuckLive> Jymmm: we got 125Mashines of them in the factory
[17:54:43] <JT-Shop> http://imagebin.org/216515
[17:55:00] <Tom_itx> http://eds.dyndns.org/~ircjunk/projects/cnc2/p1020742.jpg
[17:55:04] <Tom_itx> a classic example
[17:55:14] <Loetmichel> jeah, looks like my desing
[17:55:14] <Tom_itx> but he springloaded one side
[17:55:18] <IchGuckLive> Jymmm: max channel wide is 300x100mm extruding at 4,5m/min
[17:55:30] <Jymmm> IchGuckLive: I tried using a 45mm rotary cutting blade (usually used in sewing/quiliting) chucked in the drillpress. Once it bit into the material it cut fine. But gettign it to bite was the hard part.
[17:55:31] <JT-Shop> I guess so he is using EMC for rails
[17:55:43] <Tom_itx> conduit?
[17:55:44] <Tom_itx> yes
[17:55:46] <Tom_itx> :(
[17:55:47] <JT-Shop> yea
[17:56:02] <Tom_itx> but it's actually better than what he had
[17:56:05] <Loetmichel> Tom_itx: in my desing the springs are the bolkts that fix the bearings ;-)
[17:56:23] <JT-Shop> Loetmichel: yea, I like your design
[17:56:41] <Tom_itx> me too, the springs were just a thought
[17:56:45] <IchGuckLive> Jymmm: got you the livetime is the problem therfore we use Air and lots of bledes inside the system
[17:56:59] <JT-Shop> bbl
[17:57:18] <Loetmichel> if i had to go over it i would make some rings for the bearings
[17:57:19] <Tom_itx> obviously the conduit isn't real accurate and parallel
[17:57:42] <Loetmichel> because the outer rings of the bearings are not supposted to have a point of contact
[17:57:44] <IchGuckLive> Jymmm: Google "hager kabelkanal" pictures
[17:57:49] <Jymmm> IchGuckLive: This doens't have to be "fast", just hands off mostly.
[17:58:14] <Tom_itx> Loetmichel, yes.. they contact at the weakest point of the bearing race
[17:58:41] <IchGuckLive> at moving 50m/min with 4lanes parallel it has on my side
[17:58:57] <IchGuckLive> Jymmm: only got 500mm of mashine cutting space
[17:59:34] <IchGuckLive> Jymmm:900m/sec so no time at all
[17:59:58] <Loetmichel> what is it called in english when you bend metal back and forth?
[18:00:08] <Loetmichel> so it will weaken?
[18:00:17] <Loetmichel> in german its "walken"
[18:00:46] <pcw_home> fatigue
[18:01:08] <Loetmichel> no, i meant the process of deforming the matal, not the result ;-)
[18:01:09] <Jymmm> pcw_home: How did ya like the traffic yesterday? =)
[18:01:15] <IchGuckLive> cold roll Hardening
[18:01:19] <_abc_> 900m/sec is about 3 times the speed of sound. Are you using an AK47 for machining with bullets?
[18:01:38] <IchGuckLive> 900mm/sec
[18:01:39] <_abc_> Loetmichel: metal fatigue is the name
[18:02:02] <pcw_home> Jymmm: Looked like quite a mess (didn't affect me though)
[18:02:03] <_abc_> IchGuckLive: what are you cutting at 1m/sec?!
[18:02:03] <IchGuckLive> _abc_: Sorry B)
[18:02:13] <Jymmm> pcw_home: Ah, cool =)
[18:02:17] <IchGuckLive> PC tubing
[18:02:40] <_abc_> weird
[18:02:43] <pcw_home> I go to work by crossing the freeway, not getting on it
[18:03:22] <Jymmm> pcw_home: Well, they say that was the worse traffic in the Bay Area in 20 years. so crossing the street could be challenging =)
[18:03:29] <IchGuckLive> _abc_: http://www.conrad.de/medias/global/ce/6000_6999/6100/6120/6125/612590_LB_00_FB.EPS_1000.jpg
[18:03:53] <_abc_> IchGuckLive: okay, so you cut that, how?
[18:03:59] <Loetmichel> Jymmm: so get yourself together, look left and right and RUN like hell ;-)
[18:04:10] <Jymmm> Heh, BIG ASS plastic pipe cutter http://www.youtube.com/watch?v=1UMjZM3_-ZM
[18:04:10] <_abc_> IchGuckLive: cut to length, miter, etc?
[18:04:44] <_abc_> Jymmm: Is the traffic problem new or is it annual/monthly etc?
[18:04:48] <syyl> hey Jymmm
[18:04:55] <IchGuckLive> _abc_: extrusion at 42m/min in 4 lanes to the mashie and cut in length 2000-2005
[18:05:01] <syyl> one guy at work built such a pipecutter by his own
[18:05:04] <Jymmm> _abc_: Arson shut down the transbay tube
[18:05:13] <syyl> as a commercial one was to expensive
[18:05:26] <_abc_> arson?!
[18:05:33] <_abc_> Sick people.
[18:05:40] <syyl> it had also functionality of welding pipes with a heating-mirror
[18:06:54] <IchGuckLive> _abc_: im now on this channel cutting to the sides at 12m/min way the hell of the tool eaterhttp://www.conrad.de/medias/global/ce/6000_6999/6100/6120/6126/612649_LB_00_FB.EPS_1000.jpg
[18:07:15] <Jymmm> _abc_: Well, I think it's kinda funny. It only shows how planning (or lack there of) of one passage way can effect a 500+ sq mile area
[18:10:34] <_abc_> Jymmm: not funny. You realize how much wind this puts into the DHS control freak's sails?
[18:11:33] <IchGuckLive> Jymmm: imagine this pipecutter at -50Deg in sibiria O.O
[18:14:47] <IchGuckLive> Jymmm: http://www.youtube.com/watch?NR=1&v=Gro_m4efgvE&feature=endscreen at 1:30 you see the Blades to cut
[18:17:07] <IchGuckLive> Jymmm: catting at $:0

[19:43:48] <uw> hello i have a dxf that was made in AutoCad. However when I try to load it into PyCAM, some of the features in the .dxf are not supported.
[19:44:02] <uw> like arctext and the fonts that are used
[19:44:33] <uw> is there a way to export this .dxf into a format that can be understood by PyCAM
[19:44:37] <cradek> seems like you will have to either improve pycam or avoid using those features
[19:45:00] <cradek> you could try exploding things and re-exporting (NB I have never used pycam)
[19:46:13] <uw> thanks for your help. I guess this is more of an autocad question for how to explode this font so it isnt a font/arctext anymore. Ill try that
[19:46:37] <uw> also, if you haven't used pycam, what program would you recommend for generating gcode?

[19:47:04] <JT-Shop> jd896: I have the sheet align done!
[19:47:12] <JT-Shop> and used it yesterday
[19:47:13] <uw> it is autocad 2006 with express tools
[19:47:26] <uw> but 2008 does the same thing

[19:47:50] <jd896> Yeah I did keep poping in here but missed you found it on the forum
[19:48:23] <jd896> Ah try saving as yeah 2000 or 2004 lt those seam better cross compatible
[19:48:40] <uw> oh thats a thought too ill give that a try
[19:48:49] <jd896> You pleases with the results John
[19:49:11] <JT-Shop> ok, cool... the only thing I want to do now is to add a number readout of the rotation so I'm reminded that one is in effect
[19:50:03] <JT-Shop> jd896: yes, I'm happy with how it works and used it on some 1/4" x 8" HR flat that I had to cut from side to side a bunch of parts
[19:51:05] <JT-Shop> so I put a small square on a flat part of my Z axis and pushed it to the edge to get a better visual
[19:51:20] <jd896> Yeah good point ha funny I cut some today out of 180 x 10 flat over about 3meters could have been handy for that
[19:51:53] <jd896> I have thought about this a laser pointer would be of use here
[19:52:04] <JT-Shop> even with careful use of a tape measure the stock was not parallel to the X axis
[19:52:07] -!- micges has quit [Quit: Leaving]
[19:52:17] <JT-Shop> yep, that would be good to use
[19:53:02] <JT-Shop> need some kind of cover to protect it from plasma dust...
[19:53:44] <jd896> Alot of farley and esprit machines have them yes good point maybe housing it in a closed box section with small hole in
[19:53:59] <JT-Shop> yea, that would work
[19:55:00] <jd896> Or even better when the z is retracted the cover on the laser is open when the z is not at the top the cover over the laser section is closed simple linkage
[19:55:41] <uw> jd896, going back to R12 seemed to work better, fonts still not supported. Ill keep looking
[19:55:47] <JT-Shop> yea, a spring loaded cover with a lever so open when Z is up
[19:56:08] <jd896> Can the fonts be converted to poly lines ?
[19:56:27] <jd896> Yeah that sounds the ticket John
[19:57:06] <JT-Shop> I don't use mine enough to put a laser on it, so I'll just use the square when I need it

[20:04:57] <uw> standard explode doenst work btw. well it does, however explodes the text without the font, so it doesnt look the same.

[20:24:54] <Loetmichel> Tom_itx: me?
[20:25:00] <Tom_itx> yes
[20:25:24] <Loetmichel> all up to aluminium/brass
[20:26:27] <Loetmichel> so plywpood, carbonb fibre, glass fibre, aluminium, brass, beechwood, plastics, you name it
[20:26:36] <Loetmichel> maybe even mild steel
[20:26:46] <Loetmichel> mostly sheet material though
[20:27:02] <JT-Shop> where do you find the wood like material?
[20:27:14] <JT-Shop> all I see over here is MDF or Melamine
[20:27:36] <Tom_itx> it's probably not cheap since it's ply
[20:27:59] <archivist> its the waterproof stuff trailer floors have
[20:28:02] <Tom_itx> i can get ~1 1/4" 20-25 ply beech
[20:28:06] <Loetmichel> JT-Shop: you can buy it in germany in every hardware store
[20:28:16] <Tom_itx> but it's $$$
[20:28:29] <Tom_itx> 4% dry
[20:28:31] <Loetmichel> its the material bottoms of truck beds are lined with (for example)
[20:28:56] <Loetmichel> water resistant, sturdy as hell, relatively cheap, vibration dampening
[20:29:18] <JT-Shop> what do they call it?
[20:29:29] <Loetmichel> in germany its called "siebdruckplatte"
[20:29:38] * Tom_itx sees JT-Shop's cogs turning
[20:29:56] <Loetmichel> would translate to "sieve pressed sheet"
[20:29:59] <Loetmichel> roughly

[20:31:33] <UnderSampled> how does one make a gcode for going along a Bezier path (not NURBS. the kind with tangents)

[20:32:40] <syyl> ah
[20:32:47] <JT-Shop> buggers welded it from the inside while it was upside down, only way to get it off was to cut a notch and so remove the inside welds
[20:32:57] <UnderSampled> so like, give three points, the first one being the tangent control point from the current location, the second being the tangent control point for the destination, and the final being the destination?
[20:32:57] <syyl> a "make it work" approach ;)
[20:33:07] <JT-Shop> yea
[20:33:25] <syyl> now you got all that slag on the floor
[20:33:31] <syyl> time to clean up ;)
[20:33:32] <JT-Shop> when I'm done it will look like the factory wanted it to be that way
[20:33:47] <JT-Shop> yea it must cool first or it might melt my broom

[20:51:04] <jd896_laptop> do tell maybe of use to those that have text needs
[20:51:11] <uw> so first the current textstyle has to be set to the same as the text on the arc text
[20:51:35] <uw> jd896_laptop, can be done by explode command
[20:51:49] <uw> once it is exploded, it should now still have the same font
[20:51:58] <jd896_laptop> yes as you said buy changeing the text style

[20:52:24] <anonimasu> http://ah.io23.net/ul/files/IMAG2511.jpg
[20:52:25] <uw> then use i used the TXTEXP
[20:52:28] <jd896_laptop> thats why it looses its formating as it changes to the active style
[20:52:36] <anonimasu> start of a taperlock coupling for the ballscrew

[20:56:13] <anonimasu> nah
[20:56:32] <uw> jd896_laptop, i was reading of those problems too, but havent seen it.
[20:56:33] <anonimasu> that i'll taper thread, stick a nut onto it, until it starts to clamp, then machine it flat to my dia i want to clamp on
[20:56:40] -!- mhaberler [mhaberler!~mhaberler@] has joined #linuxcnc
[20:57:01] <anonimasu> so im sure that the screw will be clamping all around when im done
[20:57:25] <anonimasu> and paralell.
[20:57:29] <andypugh> That double-threaded screw gets screwed all the way in. Then the extension is screwed on, then the screw is _unscrewed_ using a long hex-key down a bore in the middle. Because the large diameter is a bigger pitch than the small one, that pulls the tapers together really hard. To give:
[20:57:37] <andypugh> https://picasaweb.google.com/lh/photo/XKsl4J8YIO6HccM04_sr8NMTjNZETYmyPJy0liipFm0?feat=directlink
[20:58:03] <anonimasu> same principle, but im extending the shaft of my screw so i can get whatever dia i want in the end to match another taperlock bushing
[20:58:07] <anonimasu> for the drive gears
[20:58:52] <anonimasu> my screws are smaller then my end bearings as im using a premade bearing mount off the mill
[20:59:12] <andypugh> I had a real assembly problem, I needed to put the screw and nut in together, then attach the nut to the table. Which meant that the screw could only be rather short, and that I couldn't have access to the side of it.
[21:00:28] <andypugh> I stole the idea off of Wohlhaupter

[21:01:34] <anonimasu> the tapered part
[21:02:00] <andypugh> anonimasu: No, it's a solid taper. The extension has a matching taper.
[21:02:12] <anonimasu> oh, neat!

[21:04:02] <andypugh> They are actually 90 degree serrations. It's an automotive standard serrated shaft. I got the spec from machiniries handbook.
[21:04:34] <anonimasu> I need a 4th axis.
[21:04:35] <anonimasu> -_-
[21:05:02] <andypugh> So, all you need to do to make that sort of spline is to move the end-mill across and down a bit.
[21:05:55] <anonimasu> maybe I should make that kind of differential taper too.
[21:06:00] <archivist> I did some milled knurling that way
[21:06:04] <anonimasu> I have a conical broach somewhere..
[21:06:29] <andypugh> In fact, this rather ridiculous looking setup is me cutting those serrations: https://picasaweb.google.com/lh/photo/aD3U7TVt-SvekGIitO20B9MTjNZETYmyPJy0liipFm0?feat=directlink

[21:07:42] <andypugh> anonimasu: Tapers are very easy with a CNC lathe, and they even come out the correct angle!
[21:08:04] <anonimasu> yeah but for the internal one a 12mm tapered hole is kindof hard to cut if you want it 100mm long..
[21:08:27] <anonimasu> the screw is on the cnc lathe anyway for cutting it straight

[21:20:23] <andypugh> As much as I run it at all.
[21:21:09] <andypugh> I am considering using a webcam and image recognition software so that the PC can tell which gear is engaged. It would be cheaper and neater than switches on the levers :-)
[21:21:35] <syyl> the camera way would be special ;)

[21:23:31] <archivist> I set my horizontal for boring this week http://www.collection.archivist.info/archive/DJCPD/PD/2012/2012_06_15_Adcock_Shipley/IMG_1249.JPG

[21:24:06] <syyl> i would love to see that machine running with cnc :D
[21:24:10] <andypugh> Under the sheet is a Churchill Universal grinder (cylindrical, internal, surface and tool/cutter grinder)
[21:24:39] <syyl> swiss army knife of a grinder..
[21:24:43] <syyl> nice shop
[21:24:52] <andypugh> syyl: It would be interesting to CNC, it's got 4 axes
[21:25:27] <andypugh> There is a slide in the chuck. One day I will figure out how it works.
[21:25:39] <syyl> mh
[21:25:45] <syyl> for surfacing
[21:25:49] <syyl> like with a wohlhaupter
[21:25:55] <andypugh> You can adjust it with the chuck spinning. Power feed, even.
[21:26:17] <archivist> taper boring?
[21:26:28] <andypugh> syyl: Yes, but the difference is that the handle is stationary.
[21:26:39] <syyl> ah
[21:26:55] <andypugh> archivist: In theory, but with a flat-belt drive not very accurately,
[21:27:02] <syyl> there must be a lot of gears going trough the spindle
[21:27:52] <syyl> i am everytime suprised how many interesting machines there are in the hand of home shop machinists...
[21:28:16] <UnderSampled> can I edit gcode in axis?
[21:28:19] <andypugh> That lathe would be a good CNC candidate too. It's rather nicely made, and the leadscrew is under the bed, in the middle, and covered.
[21:28:49] <archivist> what make?
[21:28:58] <andypugh> UnderSampled: Not directly. But there is an INI file setting to choose your preferred editor, which you can invoke from a menu item.
[21:29:09] <andypugh> archivist: Smart and Brown (Model M)
[21:29:12] <syyl> boley had a central feed screw for the carriage too
[21:29:16] <syyl> its pretty clever
[21:29:28] <andypugh> It's a nice idea. Double-apron too, in effect.
[21:30:26] <JT-Shop> UnderSampled: what are you trying to do?
[21:30:50] <archivist> the schaublin 120VMhas a covered screw too
[21:30:56] <UnderSampled> either NURBSs or Beziers, but I'm still trying to figure out which
[21:31:00] <syyl> *drooling*
[21:31:05] <syyl> schaublin :D
[21:31:25] <archivist> syyl, well worn out though
[21:31:30] <andypugh> http://www.lathes.co.uk/smartbrown/page7.html says that the Smart and Brown was based on the Boley.
[21:31:40] <syyl> that one last time was shown?
[21:31:49] <syyl> with the enormous pile of swarf? :D
[21:32:03] <JT-Shop> UnderSampled: I mean editing g code in axis
[21:32:10] <archivist> syyl, yes that followed me home
[21:32:29] <UnderSampled> the demo for g5.2...g5.3
[21:32:39] <syyl> would be a good candidate to overwork
[21:33:32] <archivist> still worked nicely when worn, just the tailstock wont clamp properly
[21:34:48] <jd896_laptop> is there a way to interlock outputs ?

[21:36:01] <UnderSampled> what do you think "Make this nurbs curve or surface act like a Bezier spline in the U direction (Order U must be 3 or 4, Cyclic U must be disabled)" does (from blender)
[21:36:07] <UnderSampled> ?
[21:36:51] <jd896_laptop> can the run mode be an option inn classic ladder?

[21:38:32] <andypugh> UnderSampled: Don't think we are being unhelpful, but I suspect most of us really have no clue
[21:38:42] <andypugh> syyl: Needs more metal.
[21:38:49] <UnderSampled> well, I don't so why should you? :D
[21:39:03] <syyl> more metal is on the way :)
[21:39:23] <andypugh> Mainly the green part. The torsional stiffness looks limited

[21:39:57] <syyl> yeah, i will add ribs there
[21:40:06] <andypugh> And it looks like a case where more metal = less machining, so a win-win
[21:40:27] <archivist> I think the weight balance has pushed the spindle axis too far off the rotation axis
[21:40:46] <syyl> maybe will have it cast
[21:41:02] <andypugh> syyl: Cast iron?
[21:41:08] <syyl> jep

[21:48:01] <andypugh> "in" is Latin too,
[21:48:39] <JT-Shop> bbl
[21:48:52] <andypugh> You can make an ad-hoc a-priori statement in latin.

[21:51:39] <UnderSampled> wait. NURBS don't work in 3d?
[21:52:08] <andypugh> UnderSampled: Only in two at a time.

[21:58:37] <UnderSampled> andypugh: is there an alternative to nurbs?
[21:59:23] <archivist> UnderSampled, do the path generation outside of gcode
[21:59:34] <UnderSampled> so, just linear sections?
[22:00:06] <andypugh> Short arcs
[22:00:13] <andypugh> Ideally.
[22:00:57] <andypugh> But most CAM gives tiny straight lines, so you get into the issue in that mailing list thread that I linked.
[22:01:26] <UnderSampled> what was the issue?
[22:05:04] <andypugh> Currently LinuxCNC always goes at a speed such that it can stop before the end of the next line segment. If the line segment is very short, this can mean that is moves very slowly.
[22:05:38] <andypugh> This is agreed to be a problem, and there are folk working on an improvement.
[22:06:19] <UnderSampled> ah
[22:06:49] <andypugh> But at the moment if you have a G-code program made of very short lines, and a machine with low accelleration, then the motion will be very slow indeed.
[22:07:14] <UnderSampled> and no 3d nurbs
[22:07:28] <andypugh> A partial solution is to tell the CAM to use long segments, and set the G64 blending to a suitable value
[22:07:45] <UnderSampled> they could just add the third dimension to nurbs
[22:07:50] <UnderSampled> :P
[22:08:08] <andypugh> I think that 3D NURBS do exist, but not in the main release.
[22:08:13] <UnderSampled> oh?
[22:08:18] <UnderSampled> my current object has 21 nurb points
[22:08:35] <UnderSampled> it would have 1024 if I were to "rasterize" it
[22:08:45] <UnderSampled> (bad use, I know, but whatever)
[22:11:40] <andypugh> UnderSampled: I think you need to ask on the mailing list. But my understanding is that Yishin Li at Arias Robots has added 3D NURBS to their branch of LinuxCNC.

[23:17:09] <Jymmm> tjb1: Ah, yeah, thst's just a tubing cutter.
[23:17:12] <andypugh> A normal tube cutter won't flare the ends, but will pinch them in a bit. But that's normally good, as it gives O-rings a nice entry, or makes it easier to get them into the fittng.
[23:17:41] <Tom_itx> it also decreases the flow rate
[23:17:46] <Jymmm> yep
[23:17:57] <Jymmm> no flaring, no pinching, no burrs.
[23:17:59] <tjb1> Then stuff something in the hole and expand it a bit...

[23:18:10] <Jymmm> heh
[23:18:26] <andypugh> So cut 1/2" too long, put a drill down the middle, and make a second cut.
[23:19:01] <Jymmm> cutting ss tubing by hand is a REAL BITCH even with pinching

[23:25:39] <andypugh> If you tighten it rather more than the motor torque then that really ought to be the case, I agree.
[23:26:29] <anonimasu> it's a 1mm taper over 40mm
[23:27:53] <anonimasu> err actually more -_-
[23:30:00] <anonimasu> another re-draw needed.
[23:31:13] <tjb1> anonimasu: Nice, a fellow mac user
[23:31:23] <tjb1> I gotta be honest with you, parallels sucks.
[23:31:58] <anonimasu> it works decent enough for me
[23:32:11] <anonimasu> even for cad
[23:32:26] <anonimasu> tho, magicprefs is needed to make the mouse work..
[23:32:59] <tjb1> What does magicprefs do?
[23:33:37] <anonimasu> fix the third + forth mouse button
[23:33:57] <tjb1> What mouse do you use?
[23:33:58] <andypugh> tjb1: http://imagebin.org/216583
[23:34:08] <anonimasu> the magic mouse
[23:34:17] <anonimasu> and touchpad sometimes..
[23:34:21] <Jymmm> Tom_itx: Too big diameter, but... http://www.t-drill.com/product.asp?sua=2&lang=9&s=26
[23:34:41] <tjb1> Whats that Andy? Showing you use a mac too?
[23:35:11] <andypugh> I develop LinuxCNC in XCode :-)
[23:35:21] <tjb1> Well thats over my head :)
[23:35:38] <Jymmm> andypugh: xcode?! bah! ;)
[23:36:17] <Jymmm> Tom_itx: oh and $700 too =)

[23:37:05] <Jymmm> I wonder if I can rent one
[23:37:11] -!- FinboySlick [FinboySlick!~shark@squal.net] has joined #linuxcnc
[23:37:42] <Tom_itx> buy it then sell it on ebay when you're done
[23:37:52] <Jymmm> lol
[23:37:56] <andypugh> tjb1: mainly. Also showing that Axis in 2560 x 1440 looks a bit funny,
[23:38:01] <Tom_itx> i did that once with a nail gun
[23:38:19] <Tom_itx> sold at a garage sale for a tad bit less than i paid
[23:38:38] <Tom_itx> same as renting but had a brand new tool to work with
[23:38:45] <anonimasu> it shold be 21-19mm taper that gives me 20mm at the center around the shaft.
[23:40:43] <Jymmm> Tom_itx: this looks scary http://www.youtube.com/watch?v=N0xL3FnhIIY
[23:41:11] <andypugh> Jymmm: "Features easily mashed-off stupid safety shield"
[23:41:39] <Jymmm> andypugh: hahahahaha. it was the 1/2" vibration that got me
[23:42:26] <Tom_itx> good brand
[23:42:37] <andypugh> I have seen much more comact and cheaper looking versions of the same sort of tool
[23:42:58] <tjb1> Who knows how to make an ADC?
[23:42:59] <Jymmm> andypugh: exactly, I never expected somethign like that form Milwaki brand
[23:43:01] <anonimasu> milwakuee is pretty bad stuff -_- their cordless drills smell like burning
[23:43:12] <Jymmm> I would have said it was broken
[23:43:19] <Tom_itx> i've had good luck with their corded tools
[23:43:23] <anonimasu> two of them?
[23:43:39] <anonimasu> and not the hobby kind.
[23:44:09] <Tom_itx> http://www.youtube.com/watch?feature=fvwp&NR=1&v=WVdzP53X9vw
[23:44:53] <andypugh> smelling like burning, but working isn't a problem though>
[23:45:37] <anonimasu> one died after a few weeks like 2.
[23:45:42] <anonimasu> not heavy use
[23:46:13] <roycroft> i have a milwaukee 12v cordless driver
[23:46:15] <roycroft> it works great
[23:46:34] <roycroft> i got it for free when i bought a borescope
[23:46:42] <roycroft> and it's turned out to be fantastic
[23:46:55] <roycroft> most of my battery tools are dewalt 18v, which i love, but they're big and heavy
[23:47:18] <roycroft> the milwaukee is very lightweight, packs plenty of power, and feels really good to hold
[23:47:32] <andypugh> Tom_itx: Might have worked better as a joke if the butt-crack attracted the attention of someone who knew that the problem needed to be fixed in the actual tap(faucet)
[23:47:51] * roycroft suspects anonimasu either got a couple from a bad batch or abuses tools
[23:48:13] <andypugh> I am something of a Ryobi enthusiast
[23:48:21] <Tom_itx> me too
[23:48:22] <roycroft> and my 1/2" magnum drill is a good 30+ years old now, and still works like a champ
[23:48:36] <Tom_itx> i had real good luck with their cordless drill
[23:48:40] <roycroft> i don't have much ryobi any more
[23:49:01] <andypugh> They are good enough for me, and cheap enough for me. I think that every brand is aimed at a price and level of use.
[23:49:11] <Tom_itx> B&D suck
[23:49:24] <roycroft> i'm not sure that the dewalt 18v stuff is the best in its class, but at the time i got my first 18v battery tool it was about the only thing out there
[23:49:37] <roycroft> and i stuck with it, as there's a big investment in batteries and chargers
[23:49:45] <roycroft> i agree that the b&d stuff is quite not scottish
[23:50:18] <andypugh> Hitachi / Makita feel and look great, and I have no doubt work well for ever, but hit the price point about 2x what I want to pay.
[23:50:21] <roycroft> i was looking at some new 20v bosch lithium ion tools a couple days ago, and they look pretty impressive
[23:50:34] <roycroft> were i to migrate to another platform i'd take a hard look at bosch
[23:51:02] <andypugh> Whatever, Li-Ion is wha you want.
[23:51:09] <Jymmm> no way
[23:51:12] <roycroft> nowadays, yes

[23:51:22] <Jymmm> unless yoou like replacing batreries every 24 months
[23:51:26] <roycroft> when i started investing in the dewalt 18v stuff li-ion was not an option
[23:51:40] <roycroft> you know, though
[23:51:44] <Jymmm> Ni-MH is what I go for.
[23:52:06] <roycroft> back in the mid '80s i bought a very early makita 7.2v cordless drill/driver
[23:52:16] <roycroft> ran on a ni-cad pack
[23:52:21] <roycroft> that original battery pack still works to this day
[23:52:27] <andypugh> when I first bought my current drill it got charged twice that year. it held charge, in a way that the others dont.

[23:52:32] <roycroft> i've no idea how or why
[23:52:47] <Jymmm> If you go Li-Ion when you need to replace the battery in 18-36 months, it'll cost more than to buy a new tool
[23:53:07] <roycroft> that's not necessarily a disqualifier, jymmm
[23:53:13] <Jymmm> $120 fo the tool, $80 for battery
[23:53:13] <roycroft> li-ion are very lightweight
[23:53:30] <roycroft> and if you use the tool a lot, the weight savings can be quite important
[23:54:03] <roycroft> ergonomically, and because one can pack more energy into the battery, so it lasts longer between charges
[23:54:21] <roycroft> when time is money (and it always is, to a degree), the time saved swapping out battery packs can add up
[23:54:38] <roycroft> especially if you're on a ladder/scaffold working
[23:54:40] <Jymmm> it take that long to swap a battery?
[23:55:05] <Jymmm> you yell to the ground to someoen to toss you a battery
[23:55:06] <roycroft> in some situations it can take several minutes, unless you have a backpack full of batteries
[23:55:15] <andypugh> However, I did manage to flatten that battery in less than an hour yesterday. It drilled a 64mm hole in 1/4" steel with a hole saw. Then it drilled the same hole twice in 3mm aluminium. Then it went int the circular saw, and did a 12" cut in 1/2" aluminium tooling plate.
[23:55:54] <roycroft> assuming there's someone on the ground
[23:56:07] <roycroft> and assuming it's relatively safe to toss a battery
[23:56:10] <Jymmm> if time is money, there usually is
[23:56:47] <roycroft> all i'm saying is making absolute statements does not always convey the whole story
[23:57:03] <Jymmm> Else, you've been doing this long enough to know to bring a couple spares up the scaffoliding with you.

[23:57:39] <andypugh> In fact, my cordless drill is so good that I cut the plug off my corded drill because I had a more pressing use for it about 4 years ago, and haven't felt the need to put one back.
[23:57:51] <roycroft> i can tell you, what with the problems i'm having with my hands these days, using a tool that saves a significant amount of weight is a big win for me
[23:57:59] <Jymmm> andypugh: the cord or thee drill?
[23:58:05] <roycroft> oh, i still use the magnum upon occasion
[23:58:09] <roycroft> but not very often
[23:58:58] <roycroft> i probably pull that drill out a handful of times a year
[23:59:15] <roycroft> i use my impact drill more often than the magnum
[23:59:35] <roycroft> but i have three 18v dewalt drills, and those are what get used 99% of the time
[23:59:50] <Jymmm> one for each hand?
