Back
[01:55:47] <Willburrrr2003> Ok, I have tried another disk in my system and gave me the read error...just wasn't paying attention to it when it did that to me yesterday when I read all the box It said the error was most likely from a bad/dirty drive or disk. I know the disk is good, so has to be the drive where the problem is
[01:56:38] <Willburrrr2003> I will have to go find a low cost system this weekend for my emc2 mini lathe
[01:57:02] <Willburrrr2003> It's so close to being up and running it hurts
[02:00:35] <Willburrrr2003> With setting my lathe up in emc2 I can run the lathe with all axis moving as directed,but how do I set up a tool in it so tha the tool will follow the toolpath correctly?
[02:01:07] <cradek> Willburrrr2003: not sure I understand what you're asking
[02:02:14] <Willburrrr2003> with different tooling being different lenghts, shapes, and sizes how do I set them up to use them with emc2?
[02:02:36] <cradek> in the tool table you specify tool offsets and tool tip diameter
[02:03:04] <Willburrrr2003> I am pretty new to cnc, what are offsets
[02:05:58] <cradek> it's how you tell emc where the tip of the tool is, since as you say, tools are different lengths and mount in various ways
[02:06:10] <SkinnYPuP> Offsets are what allow you to change tools and bring it to the work predictably
[02:06:12] <cradek> on a mill, you just have length -- on a lathe you have offsets in both X and Z directions
[02:07:34] <Willburrrr2003> ok, that makes sense. When I tell emc what my offset to the tip of the tool is ...this would be in reference from what point on my machine to the tip?
[02:08:28] <cradek> that's pretty much up to you
[02:08:47] <cradek> usually people have a "reference tool" which is the tool that has no offsets required
[02:09:13] <cradek> so then the tool offsets for your other tools are the differences from that ref tool
[02:10:25] <cradek> say T1 is a 1" long end mill and T2 is a 2" long end mill
[02:10:38] <cradek> if T1 is the reference tool, T2's "tool length offset" is 1
[02:11:27] <Willburrrr2003> Ok so if I am understanding this correctly, I asign a tool touch off spot and set up a "reference tool" so that it has no offsets and touches this point. then the difference between the reference tool and another tool would be it's offset value?
[02:12:41] <cradek> yes exactly
[02:13:08] <Willburrrr2003> Ok cool, I think I am wrapping my brain around this concept :)
[02:13:42] <cradek> it's simple once you "get it" I think
[02:14:09] <Willburrrr2003> Well now that I have an understanding of what it is, I should be able to get it down
[02:14:47] <cradek> yep
[02:15:05] <Willburrrr2003> And then I will be making rc heli parts in no time hehe
[02:15:33] <SkinnYPuP> been wating on some clear r/c weather here
[02:15:44] <Willburrrr2003> cool, you fly as well?
[02:16:12] <SkinnYPuP> Haven't in years but put together a 40 size trainer lately
[02:16:31] <SkinnYPuP> haven't done heli though
[02:16:45] <Willburrrr2003> Nice , I got a 450 size electric for my birthday last year and been hooked since
[02:17:11] <SkinnYPuP> Cool
[02:17:29] <Willburrrr2003> My plane is in pieces got damages in a move...box full of hard drives fell over on it
[02:17:48] <SkinnYPuP> DOH they are so darn fragile aren't they
[02:17:55] <Willburrrr2003> Uh-huh
[02:18:09] <Willburrrr2003> shame is never been in the air
[02:18:21] <SkinnYPuP> ouch
[02:18:47] <Willburrrr2003> Once I start making $$ with this mini-lathe and the soon to come milling head for it, will be able to get it fixed
[02:20:05] <Willburrrr2003> Heli clubs in the area love the idea of custom parts and I have a friends dad that makes knives and has Ideas only can be made on a cnc mill...he's willing to pay for the work...and that will pay for the lathe and then some
[02:20:48] <Willburrrr2003> Gives me a practicle reason to build a cool machine <grin>
[02:21:17] <SkinnYPuP> Awsome, I too have a few knife smith/black smith friends
[02:21:53] <Willburrrr2003> cool
[02:22:30] <Willburrrr2003> nice I have potential jobs lined up already for a machine that's not finished yet, good motivation to get it done
[02:23:29] <SkinnYPuP> I've built all the pulse jet parts but the tubing parts for #17 on here, need to case harden the swages
[02:23:30] <SkinnYPuP> http://pulse-jets.com/
[02:24:02] <SkinnYPuP> click the pulse jet link to go to their prints page
[02:27:02] <Willburrrr2003> nice design, I built a 6" chinese pulse jet that I got off that site...got it to pop but been boxed since the move as need my cnc equip to make the fuel supply to it
[02:27:30] <SkinnYPuP> :o)
[02:27:33] <Willburrrr2003> If it works will be the smallest one that I know of , as I was told under 12" wouln't work
[02:28:13] <Willburrrr2003> Machined the compustion chamber manually on my minilate was a lot of fun
[02:28:35] <Willburrrr2003> Can't wait to be able to cnc stuff, pretty excited about it
[02:31:26] <Willburrrr2003> anyone by chance have plans for an automatic tool turrnet for a mini-lathe?
[02:32:22] <Willburrrr2003> turrent* I meant to type, kb acting up again
[03:26:50] <eric_unterhausen> open office spreadsheet can't import worth a darn
[03:33:52] <SWPLinux> import what?
[04:00:05] <JymmmEMC> SWPLinux: Remember... Be at the gate 30 minutes BEFORE you were planning to be =)
[04:00:14] <JymmmEMC> or at least 15
[04:00:25] <SWPLinux> or 75
[04:01:03] <SWPLinux> at least I have a ticket that has no change fee, so if I end up needing to leave from SFO again, I can do it for free(ish)
[05:13:19] <fenn_> be at the gate n+1 minutes before you need to
[05:13:24] <fenn_> fenn_ is now known as fenn
[05:26:03] <JymmmEMC> fenn: He's down that too many times already
[05:26:28] <JymmmEMC> done
[10:33:23] <archivist> JymmmEMC, hehe new spam subject line "Are you damn ignoring me?"
[11:19:56] <Valen> evening all
[11:21:39] <JymmmEMC> archivist: =)
[11:22:44] <Valen> that has to be one of the top 10 oddest responses to joining a room i have seen, and i've been in some pretty "interesting" rooms
[11:23:35] <archivist> just a slow response to me
[11:23:49] <Valen> that would make more sense lol
[11:24:47] <archivist> there will be many conversations interlapping in irc
[11:25:50] <archivist> try where JymmmEMC is in ##php or #mysql, you have to concentrate
[11:26:00] <Valen> Looking at CnCing an existing 3 axis mill with a rotary table, not a baby one, 200 odd kg worth of steel in the thing, I'm thinking the mesa electronics 5I20 as a controller and possibly a 7I30-4 to run some servo motors
[11:26:31] <Valen> lol i was doing so much PHP recently that i have to force myself not to end my sentances with a ;
[11:27:08] <archivist> I run 3 axis and rotary for the 4th
[11:27:14] <Valen> I'm wondering where to get motors with encoders that are somewhere near the right size for the mill
[11:27:43] <Valen> and i'm thinking that the 100W drive probably won't be enough to push it around
[11:27:51] <archivist> I cant afford that size motor :(
[11:27:55] <JymmmEMC> Actually, 6hr response to me, then 1 hr reply back to him. not bad actually.
[11:28:26] <Valen> positively timely by comparison ;->
[11:28:54] <Valen> what do you use for your software toolchain?
[11:29:08] <JymmmEMC> and ironically (other than Valen's evening all), in exact order
[11:29:55] <Valen> quiet room huh
[11:30:04] <archivist> Valen, mine is standars EMC2 with steppers and hand crafted gcode
[11:30:07] <JymmmEMC> at night in US,
[11:30:22] <Valen> thaught it was coming up on morning over there by now?
[11:30:40] <JymmmEMC> (04:30:22 AM) Valen: thaught it was coming up on morning over there by now?
[11:30:55] <archivist> I do gear making so cam progs dont really suit me
[11:30:56] <Valen> night owl huh ;->
[11:31:07] <JymmmEMC> No, just up early
[11:31:25] <Valen> archivist: nifty, I was thinking of using servo motors, they should be smoother I would imagine
[11:31:42] <archivist> servo motors are better
[11:31:47] <Valen> JymmmEMC: i go to bed about that time (relativley speaking)
[11:32:30] <Valen> archivist: that's what I thought ;-> still just trying to get a handle on sizes etc
[11:33:32] <archivist> mass and acceleration, also depends on gearing (ball screw pitch)
[11:34:09] <Valen> its not a "money is no object" but splashing a bit of cash on it is ok
[11:34:36] <Valen> I'm thinking with a servo drive a quite fine ballscrew pitch would be a good idea, as they seem to typically have fairly high speeds
[11:35:43] <archivist> I think the wiki has some sizing calcs somewhere
[11:36:59] <Valen> just looking for a gut feel at the moment, don't really have numbers to enter into a calculator
[11:37:46] <Valen> what sort of size machine are you running archivist?
[11:37:57] <JymmmEMC> 25mm
[11:38:08] <Valen> thats a pretty small machine
[11:38:21] <JymmmEMC> lol
[11:39:38] <Valen> and you JymmmEMC what are you running?
[11:40:21] <JymmmEMC> Mine hasn't bee runnig for a coouple of years (don't ask).... 24" x 24" x 5" router
[11:40:52] <Valen> we were thinking about making something like that at one stage, decided to CnC up what we have first
[11:41:16] <Valen> what sort of wattage motors were you using on it?
[11:41:56] <JymmmEMC> spindle or drive?
[11:42:03] <Valen> drive
[11:42:19] <Valen> we aren't going to bother with the spindle other than start/stop at this stage
[11:42:31] <archivist> http://www.archivist.info/cnc/works2008/P1010199.JPG
[11:42:41] <JymmmEMC> Valen:
http://www.xylotex.com/StepperMotor.htm
[11:43:15] <Valen> archivist: mmmm shiny
[11:43:29] <JymmmEMC> archivist: NEMA23?
[11:43:43] <archivist> er what! some /most is re used scrap
[11:43:58] <Valen> hence shiny ;->
[11:44:03] <Valen> home made is always cooler lol
[11:44:26] <archivist> I dont do pretty :)
[11:44:26] <JymmmEMC> archivist: Is z NEMA23 or 34?
[11:45:29] <archivist> 57mm square
[11:45:54] <archivist> http://www.arceurotrade.co.uk/Catalogue/Stepper-Motors/Stepper-Motors 180Ncn
[11:46:06] <archivist> the source for mine
[11:47:06] <Valen> direct drive by the looks of things?
[11:50:07] <JymmmEMC> archivist: and Z is a dbl stack isn't it?
[11:52:45] <archivist> Z is 220Ncn motor and a fine itch leadscrew
[11:52:53] <archivist> pitch
[11:53:01] <archivist> 1mm
[11:53:28] <archivist> ex the lathe that is now the column and head
[11:53:49] <JymmmEMC> but it's a double stack?
[11:54:14] <Valen> how do you find it for speed?
[11:54:36] <archivist> speed is poor, not good at all
[11:54:37] <JymmmEMC> Valen: Um, speed isn't everything btw =)
[11:55:00] <archivist> it does take far too long to make a gear
[11:55:46] <archivist> just setting up to make a 56 tooth calender wheel for a clock
[11:56:05] <Valen> speed isn't everything but it does give you a feel for things ;->
[11:56:25] <Valen> I'm thinking i should be looking at ~300-400W motors
[11:58:50] <Valen> e brokded thar intarwebs
[11:59:57] <archivist_emc> nope just fired up xchat on the machine
[12:00:28] <Valen> so like i was saying, 400W or so seems like it would be a good ballpark for this
https://www.machineryhouse.com.au/Products?stockCode=M143
[12:01:41] <Valen> we'll be replacing the leadscrews with ballscrews
[12:06:10] <archivist_emc> cutting 56 t now :)
[12:06:53] <archivist_emc> I must get webcam working again
[12:07:23] <Valen> does it sound all nice and whirry?
[12:07:54] <archivist_emc> gear cutting sheet metal is noisy
[12:08:26] <Valen> :-< big clock huh?
[12:09:02] <archivist_emc> 47mm dia blank but only 2mm thick
[12:09:17] <Valen> steel or brass?
[12:09:22] <archivist_emc> brass
[12:09:30] <BigJohnT_> http://www.linuxcnc.org/component/option,com_kunena/Itemid,0/func,view/catid,20/id,40/lang,en/
[12:09:36] <Valen> least it should cut quickly anyway
[12:10:06] <BigJohnT_> archivist_emc: do you back that up with anything when you cut material that thin?
[12:10:15] <archivist_emc> yes
[12:10:42] <archivist_emc> backing is a smaller scrap wheel
[12:10:50] <BigJohnT_> you need to get the web cam working again :)
[12:10:58] <JymmmEMC> BigJohnT_: You just bragging that you have SW =)
[12:11:01] <archivist_emc> and a clamping one in front
[12:11:24] <archivist_emc> I got a page load error
[12:11:33] <Valen> thought if you used a fine cutter with a decent speed on brass you wouldn't really need much of one?
[12:12:36] <archivist_emc> cutters are 12-14 teeth
[12:12:52] <archivist_emc> ant running a few k rpm
[12:13:10] <Valen> a shaped gear tooth cutter?
[12:13:27] <archivist_emc> lathe spindle was never designed for the speed :)
[12:13:41] <archivist_emc> yes form cutters
[12:13:59] <Valen> I'd be half tempted with gears that size to mount the rotary table flat, use a small milling bit and just cut the profile?
[12:14:31] <archivist_emc> poor tooth profile at base then
[12:14:40] <archivist_emc> and would be far slower
[12:14:51] <Valen> I didn't think you would mesh that far down
[12:15:17] <archivist_emc> "looks" are important with clocks
[12:15:34] <Valen> urgh, the guy over the road from us must have won lotto or something, he has 2 new cars, heaps of house work done, and today he has by the look of things bought himself a horrid purple convertable
[12:16:02] <Valen> not a cool purple even, and not a cool convertable
[12:16:11] <Valen> :-<
[12:16:15] <Valen> just noisy.
[12:16:19] <Valen> anahoo
[12:16:44] <Valen> I was thinking you could also then cut any internal shapes you wanted as well archivist without having to re-mount
[12:16:54] <Valen> spokes say or fancy flowery shapes
[12:16:56] <cradek> I hear convertible-buying is a sign of a mid-life crisis
[12:17:08] <archivist> I do do spokes that way
[12:18:19] <JymmmEMC> cradek: What, topless are you going to buy?
[12:18:21] <Valen> got any pictures of completed clocks?
[12:18:37] <JymmmEMC> cradek: Preferably brunette
[12:18:47] <archivist> Valen but for abuse of a 12 thou slitting saw see
http://www.youtube.com/watch?v=adT8Dr5JZ4c
[12:19:09] <cradek> JymmmEMC: I went the motorcycle route (I've actually had one for a long time)
[12:19:21] <BigJohnT_> around here you just need a sawsall to make a convertable
[12:19:51] <JymmmEMC> BigJohnT_: Do you happen yo own a banjo?
[12:19:56] <JymmmEMC> to
[12:20:02] <BigJohnT_> LOL, no
[12:20:02] <archivist> Valen, dial and night silent and moon work in this clock
http://www.archivist.info/clock/
[12:20:31] <JymmmEMC> cradek: I haven't ridden since helmet law went into effect
[12:20:47] <JymmmEMC> BigJohnT_: ok, so not THAT bad of a hick huh?
[12:21:01] <BigJohnT_> they are trying to do away with the helmet law here in MO
[12:21:47] <archivist> cradek, is that what my outside broadcast tuck is :)
[12:21:54] <archivist> truck
[12:22:04] <cradek> what is a broadcast truck?
[12:22:14] <archivist> TV lorry
[12:22:14] <Valen> http://www.vapourforge.com/hotness/hotness_scaled.JPG is my midlife crisis
[12:22:17] <JymmmEMC> BigJohnT_: I'd wear one if funky weather, but I enjoy riding in the summer time w/o one
[12:23:12] <Valen> I had my 26th birthday on monday :-<
[12:23:23] <cradek> ok, TV lorry is lingo I understand
[12:23:30] <cradek> but sorry, no, that's not a crisis vehicle
[12:23:49] <BigJohnT_> I usually wear mine
[12:24:20] <cradek> I think I have gone without twice - once was on purpose
[12:24:50] <BigJohnT_> I've done that too
[12:24:57] <cradek> small overpowered red car does qualify (I have one of those too)
[12:25:03] <cradek> haha
[12:25:27] <Valen> small? the damn thing is 1700kg lol
[12:25:37] <BigJohnT_> or a large overpowered blue motorcycle...
[12:26:13] <Valen> my missus is the one with the bike here lol
[12:26:53] <cradek> bbl
[12:27:17] <BigJohnT_> cradek: do I need to change the manual on css?
[12:27:42] <BigJohnT_> dang I missed him
[12:28:02] <Valen> archivist what do you use the helical gears for?
[12:28:26] <archivist> that was for a customer
[12:28:37] <archivist> a bread mixer iirc
[12:29:17] <archivist> its why I need 5 axis
[12:29:38] <archivist> setting that up with 4 is a pain
[12:30:54] <Valen> what would you use the 5th axis for?
[12:31:49] <archivist> tilt to tooth angle
[12:32:15] <Valen> nifty
[12:32:45] <archivist> just finished first pass of gear
[12:33:33] <Valen> It looks like your not really limited by the speed of the mill drives in the videos, mainly by the thinness of the materials your cutting
[12:34:30] <archivist> and feeds to get the finish
[12:34:41] <BigJohnT_> I'm off to work talk to you guys later
[12:34:51] <Valen> have fun
[12:35:01] <BigJohnT_> I usually do
[12:35:32] <archivist> tell yourself to do some work today
[12:35:50] <BigJohnT_> lol
[13:06:10] <Valen> anybody have some insight on brazing aluminium to steel?
[13:06:30] <archivist> I wouldnt bother trying
[13:07:02] <Valen> trying to get a tool steel tooth onto an aluminium ring
[13:07:35] <Valen> ~400mm diamiter ring and we want to put a tool steel chunk on it to hit things with
[13:08:47] <Valen> we thaught about bolting it but its hard to do in a strong way
[13:09:15] <archivist> ally is soft crap
[13:09:27] <Valen> its strong for the weight
[13:09:40] <Valen> thats why we are using it, weight limited application
[13:09:54] <Valen> we have 8kg to spend on the ring
[13:09:57] <archivist> if you are hitting things you need weight
[13:10:22] <Valen> its a 40mm high ring, its 60mm thick aluminium or 20mm thick steel
[13:10:47] <Valen> ever heard of robot wars?
[13:11:02] <archivist> yes it was invented over here
[13:11:17] <Valen> designing our next bot
[13:11:30] <archivist> good fun
[13:12:02] <Valen> so yeah there is a weight limit
[13:12:10] <Valen> 13.6kg
[13:12:14] <archivist> I would go for steel or whatever so you can get a good joint
[13:12:39] <Valen> thing is if the ring bends out of round at all then the whole thing is completley screwed
[13:12:59] <Valen> I'd take 60mm worth of Al to stay round over 20mm of steel
[13:13:04] <archivist> design a fault like that out
[13:13:15] <Valen> not possible
[13:13:20] <Valen> the ring is a motor
[13:17:59] <jensor> Has anyone had what resembles a stuck key on the keyboard and ran jambed the tool into the work while jogging? And to cure it the onlt way is to reboot.
[13:18:03] <jensor> It turns out there is something else afoot, because when this has happened on occasion I unplugged the key board from the pc and it kept on repeating.
[13:18:44] <archivist> jensor, yes I have
[13:18:59] <jensor> welol did you find a solution?
[13:19:36] <archivist> I was under the impression it was a fault in my KVM switch at the time
[13:19:53] <Valen> its an odd failure mode
[13:20:05] <Valen> were other keys on the keyboard working?
[13:20:17] <archivist> but also could be a failure in the input
[13:20:49] <archivist> I swapped and the oter pc didnot see the repeats
[13:20:51] <jensor> In my case it exhibits this behavior in gedit as well - seems it can be any key can't force it to do it seems random
[13:21:17] <Valen> when it happens though do other key presses make it through?
[13:21:26] <jensor> no
[13:21:33] <archivist> I direct connected now and not seen the problem for a few weeks
[13:21:59] <Valen> sounds like it could be a latchup in the keyboard bit inside the PC then
[13:22:07] <Valen> PS2 style keyboard?
[13:22:12] <jensor> yes
[13:22:29] <Valen> yah i've seen that happen sometimes
[13:22:42] <Valen> nothing to do with EMC though
[13:22:59] <jensor> So it sounds like it must be a pc failure
[13:23:29] <Valen> if its happening in 2 different applications that rules out most things, It could be the keyboard causing the latchup though
[13:23:45] <jensor> however others have noted it too
[13:24:14] <Valen> in connection with playing with KVM's and the like
[13:24:40] <jensor> KVM's?
[13:24:58] <Valen> Keyboard Video Mouse switch
[13:25:13] <jensor> I see
[13:25:17] <Valen> magic box you plug a screen + keyboard etc into that connects to multiple computers
[13:25:28] <Valen> so you can drive them all from the one set of peripherals
[13:25:36] <archivist> else you have a bench mess
[13:25:57] <Valen> hmmm, i think i need more than a KVM to solve that problem for me ;->
[13:25:58] <archivist> well "normal" people do
[13:26:22] <jensor> I do use a unique setup to interface the keyboard
[13:26:29] <Valen> ?
[13:26:50] <jensor> I have a circuit that marries two keyboards to gether
[13:26:58] <jensor> thru a nand gate
[13:27:04] <Valen> thats where i'd be pointing my finger
[13:27:17] <Valen> something there is having a hickup and causing the PC to get stuck
[13:27:22] <jensor> there is a switch so that the pc onoloy sees one keyboard for booting
[13:29:37] <Valen> try a USB keyboard if its possible, it should bypass the dodgyness in the switch thing
[13:29:55] <jensor> thats a good idea
[13:30:13] <Valen> If you are using the mangled keyboard to run the jog control then just wire that up direct and use the usb one for the other stuff
[13:31:04] <jensor> How do you mean wire the jog direct - do you mean thru halui
[13:31:14] <cradek> jensor: I'd consider switching to using halui + jogwheel for your pendant
[13:31:46] <Valen> i meant just connect the keyboard controller via the PS2 to the PC rather than through the switch
[13:32:13] <jensor> I constructed a fixed control panel with the jog controls on it
[13:32:49] <cradek> what are the controls exactly?
[13:32:51] <jensor> the jog switches are wired in parallel with the 2nd keyboard circuit
[13:33:14] <jensor> I have program controls there also
[13:33:33] <jensor> run, pause, start, abort
[13:33:43] <jensor> homeing
[13:33:53] <cradek> those can all be hooked to halui and you can get rid of this keyboard hackery
[13:33:55] <jensor> estop, machine on
[13:34:53] <jensor> Unfortunately, when I started the design I didn't know enough about halui to use it
[13:35:01] <jensor> I'm ok with it now
[13:36:07] <jensor> I pulled the circuit board out of the 2nd keyboard and cut off the printed wiring to the keys and added my external wiring instead
[13:36:20] <alex_joni> cradek: yeah, but now he can type an email with jogging keys
[13:36:28] <jensor> after mapping out the keyboard
[13:36:29] <Valen> would it be that bad to re-wire it?
[13:36:33] <cradek> alex_joni: if you don't mind the occccccccccccccccccccccccccccccasional stuck key :-)
[13:37:08] <jensor> Man you guys are surely persuading me!
[13:37:17] <cradek> jensor: I think it's impressive you got that to work, but glad there's a better way too
[13:37:58] <jensor> Yea, I built a printed circuit board to hold all the parts
[13:38:17] <jensor> machined the board with emc
[13:38:48] <archivist> I get loads of "stuff" in my keyboard
[13:39:11] <jensor> what does that mean?
[13:39:16] <Valen> you need one of those roll up all sealed plastic keyboards
[13:39:43] <archivist> cant stand those
[13:39:59] <jensor> The trouble with a keyboard as you all know is it is too difficult to hit the right keys
[13:40:10] <jensor> end up messing something up
[13:40:12] <Valen> you cant type on them much but still, better than nothing
[13:41:41] <alex_joni> Valen: voice commands :D
[13:41:58] <Valen> I did that at one stage,
[13:41:59] <alex_joni> I said jog-X incremental 'dammit!!!
[13:42:09] <Valen> dunno how well it'd work in the shop
[13:42:36] <Valen> "returning to home through the job confirm?
[13:42:44] <Valen> no hell no dear god no
[13:42:50] <Valen> "action confirmed"
[13:42:52] <Valen> crunch
[13:43:32] <jensor> :)
[13:44:04] <Valen> was ok for chatting on IRC without getting out of bed though
[13:44:14] <archivist> machines get war wounds dont they !
[13:44:18] <Valen> hmmm i might have to try that again with a bluetooth headset
[13:45:02] <jensor> Valen there are keyboard covers to keep "stuff" out
[13:45:24] <Valen> probably worse than the flexible keyboard
[13:45:38] <jensor> I meant to address archivist
[13:45:43] <Valen> http://www.virtual-laser-keyboard.com/
[13:45:48] <Valen> thats what you need
[13:47:50] <jensor> There is a setup to turn key repeat off
[13:48:07] <jensor> I could then do continous thru halui then
[14:30:35] <tomp> BJT-Work: that rotation topic picture looks like more than a simple rotation, its like 'tilting' and axis ( read yaw AND pitch )
[14:30:58] <tomp> i've thought about doing that off line, but not live in emc
[14:31:18] <BJT-Work> kinda what I thought
[14:39:43] <tomp> BJT-Work: we spoke of your torch height mods a few days ago, i cant find it in the irc logs, can you clue me into the page you posted or the link into the logs ( lincoln2thelogs :)
[14:40:31] <BJT-Work> http://www.linuxcnc.org/component/option,com_kunena/Itemid,0/func,view/catid,10/id,17/lang,en/
[14:41:05] <tomp> thx
[14:42:44] <jensor> Using halui how would one implement jog faster or slower with a momentary spdt(center off) toggle switch on a control panel akin to axis which uses < or > keys?
[14:43:39] <BJT-Work> jensor:
http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Simple_Remote_Pendant
[14:45:23] <jensor> I looked at that - It seems that only has set numbers to seledcdt from rather than continuously varible jog speed
[14:46:54] <BJT-Work> the clue you need might be here
http://www.linuxcnc.org/component/option,com_kunena/Itemid,0/func,view/catid,10/id,17/lang,en/
[14:55:19] <tomp> hmm, firefox wont save pages, i found something 'ubuntu firefox modification 0.5' was loaded. i disabled and now can save the thc page... not used to weirdness like that on linux
[15:11:53] <jensor> I assume I need to use the halui pin halui.jog.speed (float,in), but i need to create an appropriate signal to drive this. I need to get from a switch contacts (faster or slower) to create the appropriate signal. Can't seem to put things together from the docs.
[15:19:35] <cnc_engineer> Hi everyone!
[15:20:06] <BJT-Work> hi
[15:20:11] <hugomatic> hello
[15:20:22] <cnc_engineer> I need to display a self defined alarm on the basis of hal pins..
[15:20:53] <BJT-Work> in a pyVCP panel?
[15:21:49] <cnc_engineer> no, something like message box
[15:22:01] <cnc_engineer> no, something like message box
[15:30:41] <BJT-Work> I'm not sure how to do that...
[15:31:04] <BJT-Work> what kind of alarm? something in g code?
[15:34:39] <fenn> i wonder if he's coming back
[15:35:43] <tomp> a pyvcp panel can be 'like' a message box . it could display a string and even substitue data into the string ( eg: rpm is %d, gear shift delayed till less than %d, presentRpm, shiftRpm)
[15:36:05] <fenn> i'm thinking the "answer" is to hack hal_manualtoolchange.py
[15:36:30] <tomp> becuz its a triggered popup?
[15:37:01] <fenn> right
[15:38:17] <fenn> h = hal.component("trigger")
[15:38:39] <fenn> h.newpin("triggered", hal.HAL_BIT, hal.HAL_OUT)
[15:39:01] <cradek> sometimes I think this should part of halui
[15:39:08] <cradek> somehow
[15:40:21] <fenn> there definitely ought to be a way to access the hal API through NML
[15:44:29] <BJT-Work> It would be real handy to be able to pop up a messagebox from halui
[15:50:50] <skunkworks_> there is a problem with popups if you don't have a real estop. Axis has a great solution for it.(scrolling errors in the window)
[15:52:31] <BJT-Work> that is much better than popups
[15:52:57] <archivist> could/should be an extra window not over the drawing
[15:54:05] <cnc_engineer> Sorry I was Disconnected so couldn't get the views about displaying self defined alarms(message box) against the hal pins Status.
[15:54:38] <archivist> logger_emc: bookmark
[15:54:38] <archivist> Just this once .. here's the log:
http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2009-04-03.txt
[15:54:44] <archivist> see that cnc_engineer
[15:59:26] <cnc_engineer> next problem I am facing is spindle stops whenever i issue the toolchange command..
[15:59:44] <cnc_engineer> How to avoid it
[16:00:09] <Valen> how do you plan on changing tools without stopping the spindle?
[16:00:18] <cradek> lathe, I assume
[16:00:23] <Valen> ahh
[16:00:28] <cnc_engineer> Yes in lathe..
[16:00:28] <Valen> * Valen has mills on the brain
[16:00:55] <Valen> isn't easy either yaknow, they are heavy
[16:00:56] <cradek> http://www.linuxcnc.org/docs/devel/html/config_ini_config.html#sub:%5BEMCIO%5D-Section
[16:01:03] <cnc_engineer> In lathe no need to stop spindle during turret rotation
[16:01:20] <Valen> yeah i know, i was just thinking mills
[16:01:46] <Valen> sowhat sort of servo motors and drivers are people using to push what around?
[16:02:07] <cradek> heh, that's an open question
[16:02:13] <Valen> heh ;->
[16:02:22] <Valen> I'm planning on CnCing my mill
[16:02:23] <cradek> my lathe has the original late-70s motors and velocity mode amps
[16:02:42] <cradek> when I retrofit my mill I will also keep the original motors and amps
[16:02:48] <Valen> one of these
https://www.machineryhouse.com.au/Products?stockCode=M143
[16:02:49] <cradek> they are also velocity mode
[16:02:59] <Valen> atm it is all rather "manual"
[16:03:49] <Valen> i'm thinking a 5I20 PCI Anything I/O card to do the scut work and i'm looking at what servo drivers and motors to hook up to it
[16:04:25] <Valen> going to replace the leadscrews with ballscrews of a pretty fine pitch and crank the RPM out of the servos
[16:04:26] <cradek> I don't know anything about buying new servos - so far for big machines I've started with old cncs.
[16:04:37] <Valen> well thats my first thaughts anyway
[16:05:06] <cradek> ballscrews are fairly coarse
[16:05:41] <Valen> you can get finer ones though?
[16:06:15] <cradek> I don't know - seems like as the balls get small, the engagament would go down, and they'd get fragile
[16:07:22] <Valen> what would you suggest?
[16:07:36] <cradek> research :-)
[16:07:44] <Valen> thats what i'm doing ;->
[16:07:53] <cradek> like I said, I don't know much about buying new screws or motors
[16:08:00] <Valen> this is called the "talking to people who have done it before" phase
[16:08:06] <cradek> ahh
[16:08:16] <cradek> wrong person then - I'll let someone else talk
[16:08:30] <Valen> lol i'm sure theres plenty of other stuff i don't know
[16:08:43] <Valen> what sort of toolchain do you use software wise?
[16:09:34] <cradek> not much. for the mill I sometimes use REALIZE (autolisp). for lathe work I usually program it by hand because the shapes are so simple.
[16:10:00] <archivist> there are a few widget writer and users some examples on the wiki
[16:10:56] <Valen> we are mainly looking to do complexish shapes so things to go from CAD to G-Code would be usefull
[16:11:09] <archivist> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Cam
[16:11:23] <archivist> latest is HeeksCNC
[16:12:20] <Valen> ooh that looks shiny
[16:12:53] <Valen> I had been looking for an open source cad program for a while, but they all seemed either crap or last updated in 1984
[16:13:18] <archivist> the writer/s hangs out in #cam
[16:13:33] <Valen> yeah i am just reading the web pages
[16:14:36] <Valen> looks 2.5D mainly
[16:14:59] <archivist> well it is a bit new
[16:15:54] <Valen> true enough lol
[16:16:23] <archivist> nag him for real 4/5 axis cam :)
[16:16:35] <Valen> i'm sure that would go down like a lead ballon
[16:16:53] <Valen> oh and i musn't forget to ask him for a firm release date for it ?
[16:16:58] <Valen> ;-P
[16:21:22] <cnc_engineer> Next question Is my spindle stops when i change mode from mdi to manual why?
[16:24:16] <cradek> that was a misfeature of emc2.2 and previous versions
[16:24:30] <cradek> there is an ini entry that fixes the spindle turning off, but not the coolant turning off
[16:24:33] <cradek> these are all fixed in emc2.3
[16:27:35] <cnc_engineer> emc live cd is availablw with 2.2.X, how can we install 2.3 on it.
[16:28:57] <cradek> check the wiki
[16:29:52] <cnc_engineer> what is wiki?
[16:30:15] <archivist> see topic ttp://wiki.linuxcnc.org
[16:38:06] <cnc_engineer> what is the way to uninstall emc on ubuntu so that we can install new version of emc
[16:38:55] <jepler> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?UpdatingTo2.3
[16:39:21] <jepler> ^^ found by entering "2.3" in the search box
[16:39:28] <jepler> it gives a step by step
[16:47:27] <Optic> hihihi
[16:49:51] <cnc_engineer> <jepler> what is the easiest way to display a message box against some hal pin status (like want to display low lube level)?
[16:51:13] <fenn> cnc_engineer: look at hal_manualtoolchange.py (not sure exactly where it's located on an installed system)
[16:51:35] <fenn> probably close by axis.py
[17:26:03] <alex_joni> this is cool:
http://www.luminize.nl/Portals/0/machine%20besturing%20multispindel%20boormachine.mpeg
[17:29:51] <BJT-Work> neat
[17:30:36] <archivist> this ubuntu fails on mpegs and wmf
[17:31:15] <alex_joni> archivist: did you install mplayer?
[17:31:30] <archivist> no I have totem
[17:31:59] <notranc> Anybody: where can I find/contact EMC users in my area? SF Bay area in my case. Thanks.
[17:32:20] <BJT-Work> users mailing list
[17:34:16] <notranc> BJT you mean ask there?
[17:34:27] <alex_joni> notranc: yeah
[17:34:27] <archivist> as well
[17:34:45] <alex_joni> notranc: you can also look at www.frappr.com/emc2/
[17:34:53] <fenn> how do they drive all those spindles?
[17:34:55] <alex_joni> but it's not really full of data
[17:34:59] <alex_joni> fenn: magic
[17:35:12] <notranc> OK, I'll try that. Did not want to bother the whole world - thanks
[17:35:29] <fenn> huh that would work. i was thinking something like a big gear and a bunch of little gears around it
[17:35:59] <notranc> Alex, that's cool! I'll poke around to see if there is anybody in my area. Thanks as always!
[17:36:04] <fenn> notranc: i think dewey garret is near there
[17:36:37] <fenn> +t
[17:36:51] <alex_joni> he's in livermore
[17:38:31] <alex_joni> JymmmEMC is also around CA somewhere :)
[17:38:57] <fenn> i think he lives in the refugee state of lost angeles
[17:39:54] <fenn> is frappr totally broken or what?
[17:40:05] <alex_joni> fenn: it's awfull
[17:40:13] <alex_joni> some parts don't load, etc
[17:42:59] <fenn> not one user in the entire state of texas? how can it be!
[17:43:00] <notranc> I have problem with frappr too. I thought it was just kubuntu firefox
[17:44:06] <notranc> map says Image Unavailable
[17:46:41] <skunkworks_> servo drive update: No smoke yet.
[17:48:39] <skunkworks_> (although I didn't know it was so easy to take out a 7812 by hooking the power up backwards for a second.) Guess that is what fuses are for. (or a diode)
[17:50:51] <skunkworks_> it only outputs 4v and gets really really hot afterwards
[17:51:24] <fenn> * fenn seconds the diode
[17:52:35] <skunkworks_> next revision.
[19:01:59] <skunkworks_> it was funny - the enabled led started flashing at about 1 second intervals. I thought - that shouldn't do that.. (the 7812 must have been thermally reseting.
[19:11:36] <issy> hi all
[19:26:48] <jepler> http://hackaday.com/2009/04/03/cnc-music-factory-still-alive/
[19:29:00] <archivist> get us the gcode and an axis display can be returned
[19:29:50] <archivist> I presume the router boards resonate nicely (no sound here)
[19:30:24] <jepler> I think our daisy.ngc is a fair bit older than this guy's program
[19:30:30] <jepler> archivist: yes, it sounds .. not terrible
[19:30:32] <jepler> clearly in tune
[19:33:37] <alex_joni> it sounds quite nice
[19:33:37] <alex_joni> the end is a bit out of tune
[19:36:01] <alex_joni> but his decimals are fun:
[19:36:08] <alex_joni> Feedrate: (newlength/oldlength) * oldfeed
[19:36:10] <alex_joni> = 1.4671598699591015644580950363551 * 0.65333 = 0.9585395578403798251074072301019
[19:37:23] <jepler> I didn't listen all the way through
[19:54:52] <jensor> I would like to move the jog slider in the axis display to set the jog speed via a remote control panel. How would this be accomplished? All I find in the docs is how to move an axis via a joypad or mpg pendant or with a remote encoder.
[19:55:58] <alex_joni> I don't think you can move the jog slider
[19:56:04] <alex_joni> but you can move the feed override one
[19:56:26] <alex_joni> halui exports pins for manipulating feed override
[19:56:37] <alex_joni> the jog slider is something that's internal to all GUIs
[19:56:58] <jensor> I don't need remote feed over ride
[19:59:17] <alex_joni> well, you can leave the jog speed slider at max, and use feed override to control the jog speed
[19:59:35] <jensor> Can something be put together via hal comps to do this
[20:00:01] <jensor> Yes I could do what you suggest but I would prefer what i had in mind
[20:00:10] <alex_joni> you need to hack AXIS for that
[20:00:21] <alex_joni> make it export a pin for setting the jog speed slider
[20:00:35] <alex_joni> and bear in mind there are 2 jog speed sliders (for linear and angular axes)
[20:00:35] <jensor> Don't want to get into that too far over my head
[20:00:40] <cradek> but that's a terrible task
[20:00:46] <alex_joni> yup
[20:00:53] <cradek> let's back up - what is your ultimate goal here
[20:01:15] <alex_joni> I suspect this is because of the second keyboard for jogging hack
[20:01:30] <alex_joni> if it were connected to halui, then you could simply set the halui jogging speed
[20:01:46] <cradek> yes halui has a jog speed setting
[20:01:53] <cradek> that's why I'm asking - I don't understand the actual problem
[20:02:18] <jensor> Ultimate goal is to set jog speed remotely and use the controls on the keyboard to jog
[20:02:48] <cradek> if you are jogging with the keyboard why do you not want to set the jog speed with the keyboard?
[20:03:05] <jensor> Yes it is because of what you mentioned alex_joni
[20:03:50] <cradek> I am still confused. If you are using keyboard emulation of some kind to jog, use the same keyboard emulation to change the jog speed
[20:03:57] <jensor> cradek it is because I have a second set of switches basically in parallel with the keyboard
[20:04:07] <jensor> remotely
[20:04:25] <cradek> still, if you are using keyboard emulation of some kind to jog, use the same keyboard emulation to change the jog speed
[20:04:41] <alex_joni> was it 1,2,3..9 ? or is that feed_override?
[20:04:45] <jensor> but I can't chage speed via the keyboard switch if I disable key repeat functjion
[20:05:07] <jensor> thats feed override
[20:05:41] <jensor> the < and > keys do this
[20:05:49] <jensor> chage jog speed
[20:05:54] <jensor> change
[20:05:55] <cradek> yes
[20:06:08] <cradek> what does it have to do with key repeat?
[20:06:19] <jensor> but only if you have key repeat enabled
[20:06:30] <cradek> well you'll have to push it several times without key repeat
[20:06:32] <alex_joni> I suspect you need to press it a couple times
[20:06:45] <jensor> more than a couple
[20:06:54] <jensor> or several
[20:07:02] <alex_joni> jensor: you can define the jog steps
[20:07:13] <jensor> yes I saw that
[20:07:17] <alex_joni> hmm.. for incremental at least ..
[20:07:30] <jensor> also for continuous
[20:24:01] <alex_joni> http://imagebin.org/44201
[20:25:42] <BJT-Work> lol
[20:26:04] <alex_joni> BJT-Work: it's free for download from M$
[20:27:36] <BJT-Work> in DOS 5.0?
[20:29:02] <alex_joni> it works on XP here
[20:29:37] <alex_joni> although some operations take a lot of time .. like browsing for files
[20:33:52] <BJT-Work> cool
[20:36:32] <BJT-Work> * BJT-Work goes for a ride on the motorbike
[20:36:40] <BJT-Work> bbl
[21:11:07] <alex_joni> good night all
[21:34:00] <BJT-Work> night alex
[22:40:15] <UncleG> SWPadnos, you there?
[22:56:39] <archivist> UncleG, a few in there have no clue what the real needs are
[23:04:31] <UncleG> understood
[23:07:41] <hypa7ia> http://hacklab.to/archives/another-musical-variation/
[23:07:42] <hypa7ia> :)
[23:09:09] <jmkasunich> hypa7ia: what kind of video is that? (doesn't play here)
[23:20:02] <hypa7ia> it's flash on vimeo
[23:20:11] <hypa7ia> you can download the original from vimeo if you want to
[23:20:21] <hypa7ia> i put it on youtube as well, which should play well with gnash
[23:20:32] <jmkasunich> yeah, I have no problems with youtube
[23:20:38] <hypa7ia> * hypa7ia finds it
[23:20:53] <jmkasunich> this is an ubuntu dapper system.... probably don't have the latest codecs, etc
[23:21:24] <hypa7ia> shouldn't need codecs as it's using flash
[23:21:39] <archivist> flash is buggy
[23:21:43] <hypa7ia> i actually uploaded it on an ubuntu box
[23:22:46] <jmkasunich> I get a still image, and "1:28" above the progress bar.... hit the play button, and the image goes black, the timer goes to 0:00 and stays there
[23:22:56] <hypa7ia> strange!
[23:22:59] <jmkasunich> the progress bar advances (in well under 1:28)
[23:23:02] <hypa7ia> are you using adobe flash or gnash?
[23:23:13] <archivist> eventually plays here on ubuntu
[23:23:35] <archivist> but I have no sound card
[23:23:36] <jmkasunich> probably adobe, I don't pay much attention to plugins once they work
[23:23:39] <hypa7ia> http://www.youtube.com/watch?v=-aVD9aBin0Q
[23:23:42] <hypa7ia> is the youtube
[23:24:09] <jmkasunich> archivist: which ubuntu? dapper, hardy, etc?
[23:24:16] <jmkasunich> aka 6.06, 8.04....
[23:24:58] <archivist> 8.04
[23:25:54] <jmkasunich> bizarre, now youtube isn't working
[23:26:07] <jmkasunich> I mean, totally not working, even the youtube.com homepage isn't loading
[23:26:19] <hypa7ia> youtube is being weird for me too
[23:26:32] <hypa7ia> time to go back to two cans and string i guess
[23:26:39] <hypa7ia> * hypa7ia gives up on this internet crap
[23:26:42] <jmkasunich> heh
[23:29:05] <jmkasunich> finally working here
[23:29:23] <jmkasunich> you need multi-axes harmony
[23:29:35] <archivist> daisy rulz

[23:41:58] <archivist> having trouble with the web irc client John_s ?
[23:42:21] <John_s> oops swapped windows and lost it, I still need to learn a lot
[23:43:07] <John_s> What was the ebay link, I lost the page and don't know how to look at paost posts if it;s possible
[23:43:25] <jmkasunich> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=110371217543&ru=http%3A%2F%2Fshop.ebay.com%3A80%2F%3F_from%3DR40%26_trksid%3Dp3907.m38.l1313%26_nkw%3D110371217543%26_sacat%3DSee-All-Categories%26_fvi%3D1&_rdc=1
[23:44:55] <archivist> jmkasunich, by the way John_s is local to me but we have not (knowingly) met yet
[23:45:16] <archivist> a new emc user
[23:45:16] <jmkasunich> s = stevenson, right?
[23:46:17] <John_s> jmkasunich, Correct. The ebay link still has 6 days to go.
[23:46:24] <jmkasunich> I remember the name from rec.crafts.metalworking
[23:46:52] <John_s> I hope you don't hold that against me <g>
[23:46:58] <jmkasunich> heh, not at all
[23:48:12] <John_s> At the moment I'm not short of machines, only getting them converted and running. I am off to Stoke in the morning to collect a Connect CNC lathe and mill
[23:48:34] <archivist> fun
[23:50:01] <archivist> I do want a cnc lathe one day
[23:51:10] <archivist> I fancy converting this
http://www.archivist.info/cnc/works2008/P1010226.JPG
[23:51:36] <John_s> After tomorrow I will have 3 but it's the lathes that are causing me the most problems, Regardles of what people say Mach can't thread correctly.
[23:52:07] <SkinnYPuP> I spotted this BP machining center on craigslist the other day , might interest someone, looks clean
[23:52:08] <SkinnYPuP> http://atlanta.craigslist.org/tls/1093873052.html
[23:52:11] <archivist> see jmkasunich's threading video
[23:53:41] <John_s> Have you a link to it ? What is that lathe you posted the link to on your website? Is it some kind of swiss lathe?
[23:53:56] <archivist> yes sliding head
[23:54:20] <archivist> this is jmk
http://www.youtube.com/watch?v=ACvRilmIKDQ&feature=channel_page
[23:58:09] <archivist> John_s, you can also solid tap with emc
[23:59:14] <John_s> Right, yes I saw that one and another two, the threading looks very consistant, not like this <g>
