#linuxcnc | Logs for 2013-03-14

[00:00:30] <Valen> got a friend with a laser hooked up to emc
[00:00:39] <Valen> any pointers for where to start with raster?
[00:00:49] -!- Nick001-Shop has quit [Remote host closed the connection]
[00:01:26] <andypugh> There is graster (check the Wiki) but I think it looks like a very clever wrong way to do it.
[00:04:07] <andypugh> I made a start at a dedicated raster setup (single purpose motion planner that takes bitmaps as inpit) But didn't get anywhere near finishing it.
[00:04:39] <ds3> rastering lasers?
[00:04:58] <ds3> a few minutes with a perl script or small C program should suffice
[00:05:14] <Valen> the problem isn't creating gcode
[00:05:18] <skunkworks> Valen: there is a guy who took graster and made it better.. let me see if I can find it..
[00:05:30] <andypugh> The problem is in LinuxCNC, synching laser to motion
[00:05:30] <ds3> what's the problem then?
[00:05:34] <Valen> the problem is EMC stops motion when you issue a spindle power command
[00:05:53] <ds3> how are you thinking of doing it?
[00:05:58] <ds3> i got it to work w/o that issue
[00:06:01] <andypugh> Spindle is _not_ the way to control laser
[00:06:09] <andypugh> M66 might be
[00:06:13] <ds3> it is the vector cut that i that issue with
[00:06:20] <ds3> spindle controls worked for me
[00:06:26] <Valen> people are saying M62 P0
[00:06:51] <andypugh> Never trust me to remember G/M codes :-)
[00:07:12] -!- ravenlock [ravenlock!~ravenlock@enlightenment/developer/ravenlock] has joined #linuxcnc
[00:07:15] <Valen> M62 P- - turn on digital output synchronized with motion. The P- word specifies the digital output number.
[00:07:23] <ds3> how is everyone else doing the rasterization?
[00:07:40] <Valen> so is the issue with going G1s repeatdly causing stopping still happening?
[00:07:57] <skunkworks> http://www.buildlog.net/forum/viewtopic.php?f=16&t=557&start=110
[00:08:02] <skunkworks> that whole thread
[00:08:04] <Valen> IE as i recall G1 X10 G1 X20 would cause it to slow/stop at X10
[00:08:09] <ds3> G1 X Y S00..... repeatedly?
[00:08:10] <skunkworks> He used a comp to fire the laser
[00:08:49] <PCW> Best way for raster is to clock out the data with the encoder/stepgen count X scale
[00:09:00] <ds3> have people considered this sequence: G00 X Y; S000 M03; Gsomethingfordrilling Pdwell; M05; and repeat?
[00:09:19] <skunkworks> ben has been on the channel
[00:09:31] <ds3> that worked for me
[00:09:46] -!- MrTrick [MrTrick!~MrTrick@] has joined #linuxcnc
[00:10:26] <pfred1> does LinuxCNC work with the nouveau video driver?
[00:10:43] <Valen> PCW that would be good
[00:10:46] <Valen> any pointers?
[00:11:11] <PCW> Yeah FIFO in and FIFO out
[00:11:30] <andypugh> Valen do you want my config to look at (and finish)?
[00:11:50] -!- tjb1 [tjb1!~tjb1@2600:1016:b103:a4a2:c1ba:8b5c:c729:f19b] has joined #linuxcnc
[00:12:02] <andypugh> Might be a challenge to guess what I intended and what is missing
[00:12:14] <Valen> lol its all above my head probably
[00:12:26] <andypugh> Maybe mine too
[00:12:30] <Valen> how are you doing it?
[00:13:29] <Valen> for reference his machine is a pport stepper
[00:14:02] <Valen> doing it all in G-Code does have some niceties to it
[00:14:17] <andypugh> Two components, userspace Python and realtime C. The idea is that the bitmap is put in shared memory where the C-code can see it. Then the C-code moves the motors and clocks out the intensity.
[00:14:36] <andypugh> I got distracted by trying to make the motion planner finite-jer
[00:14:39] <andypugh> k
[00:15:08] <Valen> sounds messy
[00:15:16] <andypugh> I might finish it one day. But possibly not unless I get a laser.
[00:15:47] <Valen> probably a good end result but it feels less good than doing it all in pure G-Code
[00:15:55] <andypugh> Well, there is no G-code, and a very simple UI that just lets you open a bitmap and say where you want the raster corners
[00:15:57] <Valen> you could raster and vector then
[00:16:12] <Valen> my C is also terrible ;->
[00:16:46] <Jymmm> +++++----+++-
[00:16:54] <PCW> finite jerk is rather gilding the lilly since you may just overscan so the ramp-up and ramp-down are all done outside the 'painted' area
[00:17:23] <andypugh> Yeah, but I do what interests me at the time. This is a hobby :-)
[00:18:00] <PCW> might be good for 3D object painting
[00:18:29] <andypugh> Yes, galvanometers and photopolymer.
[00:20:06] <PCW> For 2D raster (printers etc), overscan probably makes sense
[00:22:44] -!- asdfasd has quit [Ping timeout: 248 seconds]
[00:26:16] <MrTrick> Has anyone here built a machine with rotational axes? I've got a scara arm with planetary geared steppers, and I'm having issues with backlash.
[00:26:49] <andypugh> That's more of a hardware issue
[00:27:16] <MrTrick> I've attached a lawnmower pull-start spring to one joint, and that sort-of works. (eg some preload to keep it at one end of the travel)
[00:27:34] <MrTrick> andypugh: I understand. I didn't think there was a more general cnc channel.
[00:28:06] <andypugh> Is this a new SCARA or an old, worn one?
[00:29:35] <MrTrick> new, but custom built.
[00:29:43] <MrTrick> It's using these steppers; http://www.phidgets.com/products.php?category=23&product_id=3318_1
[00:29:49] -!- zlog has quit [Remote host closed the connection]
[00:29:54] -!- Tom_itx has quit []
[00:30:03] <andypugh> I think that they normally use zero-backlash drives
[00:31:06] <MrTrick> fair enough.
[00:31:20] <MrTrick> I bet the DIY crowd can't really get their hands on those, though...
[00:31:57] <andypugh> Do you have feedback?

[00:33:27] <Valen> MrTrick: hypocycloid gears can be pretty low backlash and cut on a DIY mill
[00:34:05] <MrTrick> andypugh: no, they're just servos. I had some success with writing some backlash compensation code, but it was a pretty ugly hack. ^_^
[00:34:10] <Valen> otherwise you can look for, garh whats the fancy ones
[00:34:23] <MrTrick> The mower spring seems to work okay, but I'd rather it had more torque.
[00:34:40] <MrTrick> and harmonic gearheads (is that what you meant Valen?) are hard to find.
[00:34:48] <Valen> thats the one
[00:35:22] <MrTrick> The "if I had to do it again" file contains those. It also contains "Run away. Run!"
[00:35:26] <andypugh> MrTrick: Have you tried the backlash compensation built-in to LinuxCNC?
[00:35:46] <L84Supper> support for laser control for SLA is in the works
[00:36:18] <L84Supper> laser modulation as well
[00:36:20] <Valen> take a look at hypocycloid gearboxes MrTrick
[00:36:27] <MrTrick> I'm actually generating gcode on the fly, in windows, so linuxCNC had a few hurdles. I'm actually using the grbl stepper control firmware at the moment.
[00:36:34] <Valen> L84Supper: for sla?
[00:36:42] <L84Supper> Valen: yes
[00:36:43] <MrTrick> Valen: Any idea where I could get some? Before Monday?
[00:36:55] <MrTrick> For NEMA17 motors? :-)
[00:36:59] <Valen> L84Supper: as in what does "for sla" mean?
[00:37:17] <L84Supper> Valen: 3d printing
[00:37:46] <L84Supper> if you only need to print one layer then it could also be used for laser engraving
[00:37:58] <L84Supper> the code that is
[00:38:40] <L84Supper> i guess you could also laser engrave with multiple passes
[00:39:30] <L84Supper> interlace the laser scan for materials that might melt if you just blasted the same area for too long
[00:39:54] <L84Supper> melt or burn/fire
[00:39:54] <mozmck> MrTrick: how do you like grbl, and have you looked at smoothieware?
[00:41:33] <Valen> MrTrick: you the guy asking on the hackspace list about winding springs?
[00:41:36] <MrTrick> mozmck: So far, it seems great. There are a few things that would be nicer like software limits, but I understand they're working on it. Some of the configuration is compile-time, but again there's development effort towards moving it all to runtime.
[00:41:42] <MrTrick> Valen: ^_^ Yes.
[00:41:55] <Valen> also to get around your backlash, occy strap from a handy wall
[00:41:55] <MrTrick> haven't seen smoothieware yet.
[00:42:09] <andypugh> Making springs is pretty easy
[00:42:24] <Valen> if you want to make the spring stronger you could shorten it
[00:43:15] <andypugh> You just need the right material (cold-drawn carbon steel, also known as Piano Wire) and a mandrel to wind it round.
[00:43:18] <MrTrick> I did try using rubber as a tensioner. It needs to wrap around the joint somewhat, to support the necessary movement. The problem is that while it works very well while tightening, when loosening it tends to 'stick' somewhat.
[00:43:39] <Valen> nah, you are missing the idea, strap from the "head" to a wall
[00:43:57] <MrTrick> Valen: works fine for the shoulder joint. Not so well for the elbow joint.
[00:44:10] <Valen> use 2?
[00:44:15] <L84Supper> laser control should also include analog modulation and also pulse width
[00:45:05] <andypugh> Sad to say, with a SCARA, if you have mechanical backlash you are probably in trouble.
[00:45:08] <MrTrick> I wound a spring from piano wire - sort of worked. I need to 3d print a holder to keep it aligned though (like a very narrow very deep spool)
[00:45:54] <MrTrick> andypugh: Oh I know. :-\ The saving grace is possibly that sufficiently strong springs should fix it - the load on the end effector is very low.
[00:46:00] <andypugh> Shouldn't be necessary with the right shape of spring.
[00:46:20] <andypugh> Think clothes-peg style spring
[00:47:53] <andypugh> http://www.opentech.org.uk/2013/cfp/
[00:48:16] <MrTrick> I have tried one of those.http://imgur.com/58rzm3E
[00:48:48] <MrTrick> I needed to redesign the elbow joint unfortunately, and I now need a flat spring.
[00:48:52] <andypugh> MrTrick: Possibly too many turns
[00:49:21] <mozmck> MrTrick: smoothieware.org the motion control is based off of grbl, but the thing runs on an LPC1769 which is a 100mhz 32-bit ARM cortex-M3
[00:49:27] -!- Tecan has quit [Quit: Ex-Chat]
[00:49:58] <MrTrick> mozmck: ah, that one. Looked at it briefly, but it's way overkill. I only need two axes. (the end effector is servo controlled through a micro maestro)
[00:50:36] <tjb1> http://jalopnik.com/ten-traffic-laws-that-need-to-change-453513991 - Motorcycle lane splitting is a no brainer huh?

[00:51:14] <MrTrick> andypugh: quite possibly. It was cut and bent from a much longer tension spring. Still, it tends to want to deform, so keeping a smooth tension is difficult.
[00:51:50] <andypugh> Yes, you need space between the coils for a torsion spring.
[00:52:52] -!- jfire has quit [Read error: Connection reset by peer]
[00:53:23] <andypugh> tjb1: Not sure. I see folk lane-splitting at ludicrous speeds. Like through 70mph traffic at 90.
[00:53:37] <Jymmm> Lane splitting is LEGAL in Calif
[00:54:21] <andypugh> ("Filtering" as we call it is neither illegal nor legal in the UK)
[00:54:53] <andypugh> Oh, and for context, I have never owned a car. 100% motorcyclist.
[00:55:19] <Jymmm> never?
[00:55:34] <Jymmm> Last I checked Fod dont make bikes =)
[00:55:38] <Jymmm> Ford
[00:55:48] <Valen> they are trialing filtering at stopped traffic here
[00:56:11] <andypugh> Yeah, I only work for Ford, I don't buy them :-)
[00:56:19] * Valen owns a ford
[00:56:31] * Valen guarantees andypugh didn't make any part of his ;->
[00:57:06] <andypugh> In truth, I once had a half-share of a Dodge Aspen when working in the UK as a student (Working as a cook on a girls summer camp. SOunds like the plot of a tawdry film)
[00:57:23] <Valen> a good tawdry film
[00:57:27] <andypugh> Err, US.
[00:59:09] <Valen> http://www.vapourforge.com/jake/general/hotness_touched.jpg my ford ;->
[00:59:50] <andypugh> No, I am fairly sure I had no part in the creation of that hideous machine :-)
[01:00:39] <Valen> you take that back heathen
[01:00:48] <Valen> the hotness is awesome ;->

[01:03:52] <tjb1> andypugh: Lane splitting is stupid
[01:04:01] <tjb1> I wouldn't trust the people in the cars or the person on the bike
[01:04:26] <Valen> they succeded in making it look ugly at least ;->
[01:04:35] <tjb1> People around here don't even use turn signals and they pull out in front of you
[01:04:35] <Valen> what is your dayjob andypugh?
[01:04:53] <Valen> somebody did that to my missus whilst she was on her motorbike
[01:05:00] <Valen> and on the phone at the same time
[01:05:17] <Valen> missus punched the driver in the face as they were merging in then sped off
[01:05:29] -!- Tom_L has quit []
[01:05:30] <tjb1> Hahaha
[01:05:45] <tjb1> Pretty brave to drive that close to punch someone though
[01:05:47] <Valen> sounds like she broke the drivers nose, apparently blood sprayed all over the screaming passenger (who had seen my missus)
[01:06:04] <Valen> the car was merging into her lane, into the exact spot she was in
[01:06:22] <Valen> I view motorcycles as organ factories
[01:06:33] <andypugh> Valen: I am a development engineer. I tell gurls I am a test driver, but that's only partly true.
[01:06:35] <Valen> IE when i need a new liver it'll probably come from a motorcyclist
[01:06:52] <Valen> i bet you have the more interesting job 95% of the time andypugh ;->
[01:06:56] <tjb1> I sold my motorcycle after I almost wrecked it in a turn
[01:07:19] <Valen> she is very sensible, she doesn't lane filter, won't sit in anybodies blind spot etc
[01:07:25] <Valen> she drives it like it was a car
[01:07:34] <andypugh> You have to be really dumb to crash a bike in a straight line
[01:07:44] -!- zzolo has quit [Quit: zzolo]
[01:07:55] <Valen> andypugh: or get run over by a truck who is changing lanes
[01:08:13] <L84Supper> motorcycles are nearly invisible to most drivers here, I used to get hit in my Alfa with the top down, drivers would say they didn't even see me
[01:08:13] <tjb1> I'd never take a motorcycle on a freeway
[01:08:15] <andypugh> There is _generally_ room for everyone.
[01:08:20] <tjb1> That draft coming off trucks is scaaary
[01:08:26] <Valen> there are a few trucks with little pointy girl fist sized dents in their doors
[01:08:37] <andypugh> It's no problem at all if you go fast enough.
[01:09:02] <tjb1> Saying you didn't see them is just an excuse
[01:09:17] <Valen> hah, 16km/hr over the limit here is ~$500 fine
[01:09:31] <Valen> 40km over is instant loss of licence and potential jail time
[01:09:38] <andypugh> (seriously, this is not macho posturing, it's physics. To cope with side winds you need to be able to generate high lateral forces, and on a bike that needs enough speed)
[01:10:03] <Valen> a 90kg rider will also help ;->
[01:10:37] <andypugh> Your lass sounds like fun :-)
[01:10:46] <Valen> she is pretty good ;->
[01:10:55] <Valen> and she really likes the new tyres we got her
[01:11:11] <Valen> used to have arrowtrax, now got bridgestone bt-45s
[01:11:19] <Valen> she has an old 250cc
[01:11:24] <Valen> the new ones are soooo crap!
[01:11:41] <L84Supper> Valen: what model is that Ford?
[01:11:46] <andypugh> Anyway. I only have a bike, I do 12k miles a year, and I haven't crashed for 10 years. (discounting a moment of over-exuberance on a racetrack)
[01:11:47] <Valen> hers is like 45+HP the new 250s are 1 cylinder of 10Hp crap
[01:11:51] <Valen> Au falcon
[01:12:05] <Valen> its australian (but thats not where the au is from)
[01:12:22] <Valen> on a race track isn't counted, your sposed to crash there
[01:12:39] <L84Supper> I haven't seen it here or in Asia
[01:12:56] <Valen> nope, australia, NZ and aparantly south africa
[01:13:11] <andypugh> Arrowmax(?) are pretty darned old. BT45s are pretty good, but I rather rate Michelin Pilot Power (might not have a 250cc fitment).
[01:13:33] <Valen> we got those ones because they are dual compound and she is mainly on the motorway
[01:13:59] <andypugh> You should buy her an R6. :-)
[01:14:09] <andypugh> Or maybe an R1, why mess about?
[01:14:24] <Valen> she really likes the 250cc
[01:14:32] <Valen> and dislikes pointy fronts
[01:14:50] <Valen> http://www.moto-data.com/moto/Yamaha-Zeal-250.jpg is what she has
[01:15:13] <Valen> it only weighs like 120kg or so
[01:15:16] <andypugh> Hmm, OK. The problem with 250s is that, in general, the parts that matter are a bit budget.
[01:15:28] <Valen> 20 odd years old, goes like stink
[01:15:40] <Valen> the new 250's are shitefull
[01:15:50] <Valen> the only thing I'm looking at doing is fuel injection
[01:15:57] <andypugh> Yeah, the engine is the least important part.
[01:16:15] <Valen> rebuilt the front shocks and everything
[01:16:22] <Valen> polished all the aluminum up too ;->
[01:16:41] <Valen> going to get a respay soon, in metallic green with butterflies, possibly an airbrush job
[01:16:52] <andypugh> My R1 chassis and suspension won't let me crash. It's all so solid and competent that as long as the tyres are on the tarmac, it can be recovered.
[01:17:21] <Valen> she is pretty good at not getting into situations that need recovering from
[01:17:37] <Valen> i think she got her wild motorcyling out a while ago on the farm when she was growing up
[01:17:52] <Valen> now its a (fun) form of A-B transport
[01:18:05] <Valen> she was banned from a motorcross track once
[01:18:18] <andypugh> That Zeal really does have very spindly forks by current standards, and that feeds an unpleasant Normal Mode
[01:18:39] <Valen> she was beating all the boys (she was like 15) so they crowded her off the track into the fence
[01:18:46] <andypugh> (Err, Normal Mode is a vibration science term)
[01:19:29] <Valen> she jumped off the embankment and rode around the corner on the wire mesh (ball of death style) that "protects" the spectators, overtook the boys then rode it back onto the ground after the corner
[01:19:37] <Valen> they said she won the race but don't come back
[01:19:56] <andypugh> "they" need to get over themselves.
[01:19:57] <Valen> she also ran her self over with a quad bike
[01:20:13] <andypugh> I think that's quite common
[01:20:40] <Valen> I've seen a few motorcross events, never seen that ;->
[01:20:59] <andypugh> That Zeal engine would make a nice 500c V8
[01:21:08] <tjb1> I had a honda shadow sport I think, one turn I almost ran it onto the berm on a turn
[01:21:12] <tjb1> sold it after that
[01:21:32] <Valen> I want to turn my falcon engine into a V12 ;->
[01:21:36] <Valen> they are brilliant engines
[01:21:45] <Valen> go for 1 million Km in taxies without a rebuild
[01:21:51] <andypugh> Yes, well, The Shadows can't actually do corners, the "Sport" part is there to confuse you
[01:21:52] <L84Supper> machine vision and laser control are the two things we are working on, the vision system may be used to align the machine to fiducials or the edges of parts
[01:22:06] <tjb1> I dont remember what it was but it was only like a 600
[01:22:10] <L84Supper> both should be done by the summer
[01:22:31] <tjb1> If I would have hit the berm I would have been slamming into trees at 50 mph
[01:22:31] <Valen> I'm going to need to richen up her mixture, friend rebuilt the carbs and the power band is at 8k plus, which is fine for racing, but she rides it up to 8krpm
[01:23:04] <Valen> i figure running it a bit rich should increase the torque and drop the power band somewhat
[01:23:06] <andypugh> tjb1: The trick is to lean far enough.
[01:23:18] <tjb1> I know
[01:23:19] <tjb1> :)
[01:23:57] <Valen> missus is also short, so many of the 600's the seat is too tall for her
[01:24:21] <andypugh> Valen: Maybe. Maybe an air leak if it isn't meant to be like that, and I would check the carb diaphragms on any 20 year old bike.
[01:24:31] <Valen> they are aparently ok
[01:24:46] <Valen> its a difference since the rebuild
[01:25:01] <Valen> it also doesn't start when "cold" as well as it used to

[01:25:52] <Valen> She is somewhat keen on the idea of a falcon engine (I6) bike
[01:25:59] <Valen> it'd be a "cruiser" ;->
[01:26:26] <Valen> only 220Kw or so, but 450Nm of torque or so at 2000 RPM
[01:27:21] <andypugh> Just find her a Benelli Sei?
[01:27:32] <Valen> andypugh: hah, she would be dead in 5 minutes on the motorway as everybody runs her over without seeing her
[01:27:49] <andypugh> Eh?
[01:28:03] <Valen> on the indian
[01:28:32] <andypugh> If she was doing 200mph they coiuldn't?
[01:29:02] <andypugh> I doubt that Indian is slow.
[01:29:36] <andypugh> Even the Americans can't make an 1800cc engine make less than 100hp

[01:37:06] <Valen> kinda loud though

[01:38:15] <Valen> probably more than that
[01:40:07] <Jymmm> ok, spindle and cooling pump motor, how's that?
[01:42:37] <pfred1> andypugh a guy I knew his uncle holds the worlds record for HP per cubic inch
[01:43:01] <andypugh> That's a record I would love to hold :-)
[01:45:27] <pfred1> google jim feuling engineering quad 4 turbo
[01:46:11] <pfred1> he's dead now but I think his record still stands
[01:47:41] <pfred1> something like 2,500 HP out of 184 cuin ?
[01:48:51] <andypugh> Talk about nominative determinism.
[01:50:55] <L84Supper> what type of fuel?
[01:51:46] <pfred1> I don't know
[01:51:57] <pfred1> car ran 221.663 MPH though
[01:52:15] <pfred1> not bad for a 4 banger
[01:53:55] <L84Supper> super fuel gets 8500-10K HP out of a 426 cu in
[01:54:03] <pfred1> Larry told me when he went to visit his uncle he had sheds in his backyard where he would run engines
[01:54:12] <L84Supper> http://en.wikipedia.org/wiki/Top_Fuel
[01:54:15] <pfred1> run them til they blew up
[01:54:55] <pfred1> hemis are awesome motors out of the factory
[01:55:06] <uw> L84Supper, 500ci
[01:55:30] <pfred1> the best drag is a 426 vs a 440
[01:56:28] <L84Supper> and about as reliable as a Jeep :)
[01:56:43] <pfred1> the 440 will be halfway down the track and the hemi will just be coming off the line then all of a sudden it is like the 440 just stopped and the hemi shoots right by it
[01:56:51] <Tom_itx> cuda 440 6 pak
[01:57:16] <Tom_itx> that was a fun one
[01:57:39] <pfred1> 440s are truck motors
[01:58:00] <Tom_itx> was it a 383?
[01:58:02] <Tom_itx> i forget
[01:58:04] <pfred1> I knew a guy who had a 426 superbird
[01:58:07] <Tom_itx> i bet it may have been
[01:58:11] <pfred1> the 340 was nice
[01:58:26] <Jymmm> Heh, I had a 76 Buick Rivera with a 455 , Full to empty in 3.4 miles!
[01:58:32] <pfred1> 340 cuds were something to be reconed with

[01:59:41] <Tom_itx> yes it was a 440
[02:00:09] <pfred1> people liked them because it was a big number and they were fast but back then there was plenty faster
[02:00:13] <Tom_itx> http://www.youtube.com/watch?v=9XuyxcMIykY
[02:00:34] <Tom_itx> similar
[02:01:33] <L84Supper> Jymmm: I had a 66 Chevy pickup with a 454 that had about the same mileage :)

[02:07:19] <L84Supper> fun truck
[02:07:36] <Jymmm> L84Supper: yours?
[02:07:48] <andypugh> Tom_itx: It's a big engine, and claims 390hp. But it isn't actually very fast is it?
[02:07:51] <L84Supper> was, sold it a few years ago
[02:07:57] <Jymmm> L84Supper: WHY?!
[02:08:14] <Jymmm> L84Supper: and how much?
[02:08:44] <L84Supper> now I drive land tanks
[02:09:03] <L84Supper> slightly better mileage but they never break
[02:09:14] <Jymmm> L84Supper: and how much?
[02:09:50] <andypugh> I have never figured out how a 400hp US car can be so much more languid than, for example, a 400hp Ferrari.
[02:09:59] <L84Supper> http://imagebin.org/250179 heh, don't remind me

[02:13:20] <andypugh> OK. But in that video that Cuda makes a lot of noise, and looks great, but the lamp-posts are hardly flashing past
[02:13:59] <pfred1> when I was in high school one kid owned a 71 cuda and he lost control on this one stretch of highway man it was legendary
[02:14:28] <pfred1> he did like 2 360s through this S turn and didn't hit anything
[02:15:09] <andypugh> That could be huge power, it could be a bad driver and 1970s tyres
[02:15:26] <Jymmm> I did a 540 once, ended up the front tires were BOTH touching the curb =)
[02:15:26] <pfred1> oh it was total dumb luck
[02:15:51] <pfred1> I mean if you knew the guy he wasn't the type I don't even know why he had the car
[02:15:56] <Jymmm> You just gotta love hand brakes =)
[02:16:13] <pfred1> the best is doing Js
[02:16:25] <pfred1> when you ram a car in reverse while you're driving
[02:16:37] <pfred1> and do a J burnout
[02:17:01] <pfred1> not every car can do it
[02:17:19] <Jymmm> Nah, I was always afraid I'd drop the tranny if I ever tried =)
[02:17:23] <pfred1> a 64 Belair can though
[02:17:47] <pfred1> well he did own his own tow truck the kid that did those
[02:18:14] <L84Supper> heh, I did that once in heavy traffic, 180's back and forth 3-4 times, ended up with two wheels up on the curb but didn't hit a thing
[02:18:14] <pfred1> so if the trans dropped out he could pick the whole mess up
[02:18:27] <Jymmm> LOL, so does a friend, we got my car stuck, then got his tow truck stuck =)

[03:05:47] <pfred1> pcw_home I had rtai running but when I went to start X Window it wouldn't then when I got X Window running the RTAI environment got lost
[03:06:11] <L84Supper> tjtr33: Parker is 3-4 lead time, nut you can expedite for a fee, the problem is if they run late you just get the extra fee back
[03:06:23] <pfred1> so I've done some research and thought maybe the kernel from LinuxCNC might be better but so far I cannot figure out how to get it
[03:06:24] <pcw_home> Thats a head scratcher...
[03:07:00] <pfred1> see the Ubuntu 10.04 kernel was patched to run the nouveau video driver
[03:07:18] <Valen> any paticular reason for using nouveau?
[03:07:28] <pfred1> but if nouveau is in 2.6.38 damned if I can find it
[03:07:41] <pfred1> Valen the nv driver is pretty sucky
[03:07:49] <Valen> works ok for me
[03:07:53] <Valen> or at least it did
[03:07:57] <pfred1> don't mean it ain't sucky
[03:07:59] <Valen> dual cpu host though
[03:08:15] <Valen> using nvidia driver
[03:08:20] <pfred1> for real nVidia cripples it on purpose
[03:08:40] <pfred1> their stated policy is run our binary driver
[03:08:42] <Valen> I was getting 4000 latency with that machine
[03:09:06] <pcw_home> I thought the nouveau driver had latency problems
[03:09:11] <pfred1> it might
[03:09:38] <pfred1> I haven't been able to check it out other than on the LinuxCNC CD
[03:10:36] <pfred1> I try to install the kernel sources with the CD and I get nothing
[03:10:53] <pfred1> if there is some trick to it I'm not figuring it out
[03:11:07] <pcw_home> You just want to try the binary ubuntu 10.04 kernel?
[03:11:16] -!- Valen has quit [Quit: Leaving.]
[03:11:21] <pfred1> no I want to pull the source and build it
[03:11:53] <pfred1> but nothing downloads a couple text files and that is it
[03:11:58] <pcw_home> you are a glutton for punishment
[03:12:30] <pfred1> dpkg -L linux-source is like 2 text files
[03:13:02] <pcw_home> probably only the linuxcnc config info
[03:13:05] <pfred1> yeah the whole LinuxCNC thing is like a rock and a hard place

[03:13:25] <pcw_home> try xenomai?
[03:14:55] <pfred1> I don't know what it is
[03:15:30] <pfred1> technically if the kernel source can't be produced the program cannot be distributed
[03:15:31] <pcw_home> You probably need to ask build questions on the devel list when there is someone there
[03:15:49] <pfred1> I mean the Linux kernel is GPL
[03:15:52] <pcw_home> you need to get it from Ubuntu

[09:05:45] <mrsun> when factories makes gears i would guess they have a long blank and cut it all to a gear then cut that in slices? :)
[09:08:19] -!- fomox has quit [Ping timeout: 264 seconds]
[09:09:04] <toastydeath> mrsun, no not usually.
[09:09:09] <mrsun> oh =)
[09:09:22] <mrsun> felt like that would be most natural to do like 1 meter pieces then just slice it =)
[09:09:34] <toastydeath> gearmaking machinery does not deal well with long gears
[09:10:22] <toastydeath> Casting and forging are very common methods to make blanks, because the central hub needs to have some degree of accuracy and long bores are not, in general, accurate
[09:10:43] <mrsun> ahh =)
[09:11:39] <archivist> I have made sticks of gears and sliced but there are issues with burs
[09:12:38] <archivist> generally only an inch width when making thin stuff for clocks
[09:13:30] <archivist> see top left pic http://gears.archivist.info/
[09:14:59] -!- fomox [fomox!~chatzilla@77-110-193-140.inet.signal.no] has joined #linuxcnc
[09:15:35] <toastydeath> also, lots and lots of gears are forged, and when you cut a forged gear, you take away some of the strength
[09:16:02] <toastydeath> so generally, only the teeth and central bore will be cut; you wouldn't wantr to do any sort of parting
[09:16:09] -!- vladimirek [vladimirek!~vladimire@] has joined #linuxcnc
[09:17:30] <archivist> clock gears are a bit of a special case as the bore is often too small for mounting on
[09:17:36] -!- vladimirek has quit [Client Quit]
[09:18:47] <mrsun> toastydeath, would it realy be much even if you face edges etc .. as the grain structure still will "flow" in the right directions inside of the gear
[09:19:16] <toastydeath> the deformation is greatest at the skin
[09:19:20] <toastydeath> and thus the hardness
[09:19:30] <toastydeath> the smallest cuts are, proportionally, the most damaging
[09:20:19] <mrsun> hmm k =)
[09:20:27] <toastydeath> a gear blank struck in a press will be far more tolerant than one struck with a drop hammer, but the problem is still there
[09:20:33] <mrsun> oh well, dog seems to want a walk .. have to go :P
[09:20:37] <toastydeath> the majority of the lattice deformation is near the surface
[09:21:05] <mrsun> toastydeath, yeah i guess it is as that will take the most preasure from the forging =)
[09:21:42] Cylly is now known as Loetmichel
[09:21:55] <mrsun> know from when i was doing blacksmithing that a stock of say 1" or so its hard to get deformation in the center when forging it =)
[09:22:04] <mrsun> as the surface flows FAR faster =)
[09:22:11] <toastydeath> yep
[09:22:40] <Loetmichel> *grrr* can anyone send me into the right direction to get a RTL8192c wlan stick runnung under LinuxCNC (Ubuntu 10.04)?
[09:22:41] <mrsun> making it < formed in the tip (a cave) =)
[09:23:02] <Loetmichel> running
[09:23:10] <Loetmichel> mornin' btw.
[09:41:36] * Valen has seen custom gear makers that do the sticks of gears
[09:41:59] <Valen> they make a long stick, then machine it all up then case harden then grind if its important
[09:44:39] <Valen> archivist: that merlin clock is darn shiny looking

[18:43:50] <pfred1> mk0 well I kind of want to get away from Ubuntu too
[18:44:07] <pfred1> I won't have that stuff around me!
[18:44:27] <pfred1> no shopping lens for me thank you very much
[18:45:34] <mk0> :) try on, i think kinda useful information
[18:45:37] <pfred1> why LinuxCNC chose Ubuntu as their BDI distribution I've no idea
[18:45:48] <mk0> there is an idea
[18:45:55] <pfred1> it is about the last distro I'd pick for performance
[18:46:40] <mk0> you can use another distro, the process of xenomai installation is dexcribed
[18:46:56] <Connor> pfred1: What's wrong with Ubuntu ?
[18:46:58] <pfred1> I have one Debian box that runs LinuxCNC now
[18:47:16] <Connor> I don't like the new Unity.. I'm still running 10.04.. but still..
[18:47:31] <pfred1> Connor they target the casual desktop user so that has its drawbacks
[18:47:37] <mk0> ))))))))))
[18:47:44] <mk0> uninstall unity
[18:47:55] <pfred1> yes you have to uninstall a lot of things
[18:48:01] <pfred1> too many things
[18:48:10] <mk0> okay)
[18:48:22] <Jymmm> Ubuntu == Dependancy Hell
[18:48:45] <pfred1> yes once you pile a mound up in a distro it is hard to shovel what you don't want off
[18:49:01] <Jymmm> I uninstalled mplayer once and it took out all of X too!
[18:49:02] <pfred1> easier ot start with less and add just what you want

[18:49:22] <pfred1> hmmm mplayer is a nice program
[18:49:45] <Jymmm> not if you dont have a sound card
[18:49:47] <mk0> you can use any distro. then install xenoamai or rtai what's the problem?
[18:50:02] <pfred1> I took apache out once and that took out networkmanager
[18:50:19] <mk0> man apt
[18:50:19] <pfred1> mk0 the latest kernel rtai supports is 2.6.38
[18:51:12] -!- Spida has quit [Ping timeout: 264 seconds]
[18:51:24] <mk0> why would you uninstall something at all? just install gnome2 or часу and use it.
[18:51:28] <pfred1> I normally don't need networkmanager but that was on a laptop and I never could get wifi to work without it
[18:51:48] <mk0> or xfce
[18:51:50] <pfred1> mk0 because my computer systems do not have unlimited resources to run things I do not want
[18:52:17] <mk0> it's just some Gb
[18:52:32] <mk0> you can use minimal CD
[18:52:53] <mk0> anyway i do not see aproblem
[18:53:44] <Jymmm> pfred1: I understand your frustrations with certain things, but CHILL OUT! It is what it is or isn't in that case. Just move on to what you want instead of ranting about things you have no control of.

[19:01:49] <pfred1> someone should ask Mark Shuttlesworth how much he cares about LinuxCNC because I think he opinion would have some weight in the matter

[19:21:29] <IchGuckLive> pfred1: why changing from ubuntu there are somany CAD CAMS on it
[19:21:31] <pfred1> hmmm I'm looking in the RTAI source tree and under /usr/src/rtai/base/arch/x86/patches the highest i am seeing is hal-linux-
[19:21:39] <IchGuckLive> it is a perfect workaround
[19:22:14] <cradek> pfred1: if you're interested enough to build rtai, you should be watching the rtai mailing list
[19:22:16] <andypugh> pfred1: I think you need to get the source from their CVS.
[19:22:28] <pfred1> IchGuckLive generally what one Linux distribution can run all of them can that falls short when some library version requirements are not met though
[19:22:35] <pfred1> andypugh ah this is the tarball
[19:22:47] <pfred1> 3.9
[19:23:31] <pfred1> andypugh I almost had it the other night but the kernel is so old it didn't have the right video driver so X Window wouldn't run by the time I fixed that I broke my RT environment somehow

[19:24:29] <pfred1> andypugh now for some strange reason that OS thinks the PC only has 839MB of RAM installed

[19:24:59] <pfred1> and i memtested it and it is OK
[19:25:19] <pfred1> that suggests to me there are deeply seated problems that need to be addressed
[19:25:29] <pfred1> wipe out!
[19:25:45] <pfred1> I did some really stupid stuff to get X Window t orun
