[00:54:32] <andypugh> Wow! an 18V drill for £10. That must have almost 10 amp-minutes capacity.

[00:54:55] <andypugh> Leave him, it's less scary than the knives and machetes

[01:00:37] <andypugh> If you are going to extend that one you keep showing, you will straighten the end out before you break the pipe

[01:48:21] <Danimal_garage|2> i remember we had this air compressor for a submarine in the shop, and one of the guys was disassembling it, and we were told it was discharged, but as he got to the last bolt on the end plate, it shot off and went through the wall

http://www.youtube.com/watch?v=lzraVXP-5KQ
[02:13:41] <FinboySlick> Hypnodisk did quite well in that series.
[02:13:48] <FinboySlick> hypno disc that is.
[02:26:28] <andypugh> http://www.youtube.com/watch?v=2CvT0tLQB1I (SMIDSY was my robot)
[02:27:11] <FinboySlick> andypugh: You one of these three guys?
[02:27:35] <andypugh> One in the middle with the beard
[02:27:51] <FinboySlick> Awesome, I'm pretty sure I remember watching you when it aired :)
[02:29:00] <andypugh> Another video has a comment saying that we were the best robot never to escape the heats, which seems fair.
[02:29:46] <FinboySlick> How dangerous were they anyway? They always seemed to me likre being a bit more for show.
[02:29:50] <andypugh> OK, the _other_ one with the beard, who never says anything.
[02:30:43] <FinboySlick> I dreamed of designing one that would kill one of the house robots ;)
[02:30:45] <andypugh> The robots? Some were properly dangerous. The big pneumatic axes could have killed you.
[02:30:56] <FinboySlick> I meant the flames.
[02:31:06] <FinboySlick> The robots looked plenty dangerous.
[02:31:31] <andypugh> The flames were no problem, we had mesh over all our vents (Davy Safety lamp style)
[02:32:56] <FinboySlick> andypugh: Wow... I'm envious, I really dreamed of competing in that show.
[02:34:12] <andypugh> It just took a bunch of time and money. We were lucky that 200 people on a bike mailing list bunged £10 each into the pot. :-)
[02:34:28] <FinboySlick> I imagine.
[02:34:43] <andypugh> But that was the sort of budget.
[02:35:33] <FinboySlick> I still have a pretty clever high-mass spinner design stashed somewhere.
[02:36:25] <andypugh> I want to make a jaws-of-life style 2-wheeler. Just an _enormous_ set of jaws acting as chassis and everything.
[02:36:52] <FinboySlick> andypugh: Let's start a new international league!
[02:37:56] <andypugh> I could make a much better one now, with the equipment and knowledge I have built up since.
[02:38:43] <FinboySlick> I wonder why the show faded, it was quite popular where I lived.
[02:38:55] <andypugh> Copyright disputes
[02:39:21] <FinboySlick> Damn lawyers.
[02:39:50] <andypugh> Imagine robotwars with Arduinos..
[02:40:28] <FinboySlick> As in autonomous, or merely how much easier it would make the electronics side of things?
[02:40:41] <andypugh> We had all sorts of problems with proprietary interfaces.
[02:41:43] <andypugh> The Radio to Electronic Potentiometer link board was cheap enough, but fragile and supply was very limited.
[02:42:22] <andypugh> And we had to do mixing in the transmitter.
[02:42:27] <FinboySlick> andypugh: I assumed you used standard RC radios.
[02:43:06] <andypugh> Some did, a lot had an RC servo turning a physical potentiometer linked to a golf-buggy controller.
[02:43:53] <andypugh> Which, actually, isn't a bad system, as it is very resistant to RF noise
[02:44:25] <andypugh> And as long as the reciever sees more forwards than back, you go forwards.
[02:44:44] <FinboySlick> My design didn't require power control on the main drive so it could have been relay-driven.
[02:45:14] <andypugh> Nowadays, you would use a smart filter in the onboard electronics. (which would be an Arduino, just because you can buy and program a spare in a hurry)
[02:45:41] <andypugh> Sump Thing used 4 starter motors. A forwards and a reverse one for each wheel :-)
[02:46:11] <FinboySlick> Clever. And they have lots of torque.
[02:46:25] <FinboySlick> I wouldn't have thought of those.
[02:48:22] <andypugh> Well, they are very heavy, very inefficient, and you need one for each direction. So not the best choice, but cheap.
[02:48:44] <andypugh> The 100kg weight limit was the real problem.
[02:49:07] <FinboySlick> I'd say challenge more than problem.
[02:50:00] <FinboySlick> I love how compact and sturdy SMIDSY was.
[02:50:34] <andypugh> It was _full_
[02:50:46] <andypugh> It took 3 of us 24 hours solid to strip and rebuld.
[02:51:11] <FinboySlick> I assume you guys kept it.
[02:51:28] <andypugh> No, we sold it to someone who campaigns it in the hobby circuit
[02:52:11] <FinboySlick> I should look around Canada, maybe we have a similar hobby circuit.
[02:56:01] <andypugh> Cool! Robots fighting their way out of a caravan

[15:10:53] <geo01005> has anyone used EMC2 for cell based manufacturing with multiple EMC2 controlled machines?
[15:11:41] <geo01005> I understand that was one of the main points to the original EMC project, that concept seems to have been lost in the development of emc2,
[15:12:00] <geo01005> or at least those who have done it haven't documented it.
[15:15:57] <awallin_> not many hobbyists have pallet-changers, robot-hands, etc. that move workpieces from one machine to another..
[15:15:57] <archivist> not sure using in a cell needs separate docs as it can respond to pins and set pins which can be connected between machines
[15:16:29] <archivist> see also classic ladder
[15:17:54] <geo01005> yes, simple things can be handled with discrete IO, but things like synchronized motion between two machines would be quite difficult.
[15:18:55] <geo01005> an extreme example:

[16:42:56] <geo01005> "a

[16:44:19] <geo01005> The part of the EMC2 project I like the best is the HAL.
[16:44:34] <geo01005> I think that there are quite a few people who also think that is the case.
[16:45:37] <geo01005> Perhaps a worthwhile branch of EMC2 would put all the functionality of EMC in distributed HAL components.

[16:54:56] <tom3p> geo01005, i agree HAL is a very strong tool, i use it for non-EMC motion of simple stepper joints. i dont think all of EMC could fit well inside HAL though. ( HAL is 'subset' of EMC )
[16:54:57] <syyl_> hmm
[16:55:24] <syyl_> will a 1024 signals encoder suitable for a milling spindle, when i want to do rigid tapping?
[16:55:42] <syyl_> are there any experiences?
[16:57:39] <JT-Shop> 1024 should be fine, I think I have 2000 on my lathe iirc
[16:57:56] <syyl_> ok
[16:58:11] <syyl_> and will i get problems, if i couple it via a timing belt to the spindle?
[16:58:39] <FinboySlick> If there's a dev or two areound, I think I found the issue I had with building emc-dev. Seems the linker is missing a few -lintl options here and there. I'd like someone familiar with the build/configure script to give me a couple pointers on proper implementation of a patch (I can fix it myself but I'd like to fix it right and submit a patch).
[16:59:34] <tom3p> fwiw: theres been some talk recently about guis for hal wiring.
[16:59:42] <tom3p> i stumbled upon a manual for some math that used a beautiful system.

[19:29:31] <skunkKandT> no - just a random youtube video. sorry
[19:30:28] <skunkKandT> I have not stepped into the brushless amp world.. (other than some smallish amc drives)
[19:35:00] <skunkKandT> wait - that looks brushed
[19:35:28] <awallin_> brusched even..

[20:37:58] <skunkKandT> first 5 tool program. so far so good ;)
[20:39:35] <n0b> I just wanna jog around the table. Will m06 by itself on a line be good enough to stop emc and bring up the tool change okay box? ie I dont need t3 or something?

[20:44:15] <skunkKandT> fragalot: looks like a monarch..
[20:44:26] <fragalot> Hm.
[20:44:26] <skunkKandT> we have something similar
[20:44:28] <fragalot> Neat ^_^
[20:44:39] <fragalot> I love it :P
[20:44:51] <skunkKandT> very good lathe
[20:45:06] <fragalot> it's my friends' .. he's had to move the dc generator to another room because of the noise it makes :/
[20:45:48] <fragalot> doing this has resulted in the quietest lathe i've ever heard in my life O.O
[20:45:54] <fragalot> or well, not heard
[20:46:39] <skunkKandT> we got rid of the motor generator and just made up a dc speed control
[20:46:53] <skunkKandT> some day it will probably get a vfd
[20:47:01] <fragalot> he's thinking of doing that too, just wondering how
[20:47:22] <skunkKandT> if you still want to use the 2 speed gearbox - you would need to do some machining
[20:47:25] <skunkKandT> iirc
[20:48:14] <fragalot> hm. I do quite like that feature :/
[20:48:17] <skunkKandT> and yes - it is pretty quiet with just the dc motor running
[20:48:54] <skunkKandT> it would be a he4ck of a machine to cnc.. but the purist would be upset. ;)
[20:49:09] <fragalot> lol yeah
[20:49:25] <fragalot> but to be fair, that machine already has a lot of tools to assist you when making something
[20:49:43] <fragalot> like a nice stop on all of the axis so you don't have to worry too much about going too far
[20:50:02] <fragalot> I miss that on new conventional lathes :/
[20:50:10] <skunkKandT> yes
[20:50:38] <skunkKandT> for some reason I don't have a picture of the whole lathe..
[20:50:39] <skunkKandT> http://electronicsam.com/images/monarch/saddle.jpg
[20:51:08] <skunkKandT> http://electronicsam.com/images/monarch/gearbox.jpg
[20:51:11] <fragalot> seems to be .. missing bits
[20:51:34] <skunkKandT> it got dropped
[20:51:36] <skunkKandT> ;)
[20:51:40] <skunkKandT> why we got it so cheap
[20:51:43] <fragalot> lol
[20:52:01] <fragalot> should be an easy part to replace i'd imagine?
[20:52:07] <andypugh> n0b: Not sure I understand the question, but M6 won't do anything unless it causes a tool _change_
[20:52:20] <skunkKandT> well - we got it working - using it ever sense.
[20:52:35] <fragalot> :D
[20:52:41] <fragalot> On a different matter
[20:52:56] <andypugh> Typical American lathe, with the saddle traverse handle exactly where all the hot chips fall.
[20:52:58] <fragalot> anyone here able to suggest me a decent mini lathe? (desktop sized)
[20:53:05] <fragalot> andypugh: haha
[20:53:24] <fragalot> andypugh: that's why it's got the feed handle further away
[20:54:12] <andypugh> Seriously, American lathes have saddle on left hand, slide on right, UK lathes have them the other way round (In general) with the saddle traverse at the tailstock end of the apron.
[20:54:58] <fragalot> I've used both.. on the monarch it's not too bad to be fair
[20:55:26] <fragalot> then again I mostly use the feed :/
[20:55:29] <andypugh> http://www.kinzers.com/don/MachineTools/shop/Colchester_Mk1.jpg as an example
[20:55:42] <andypugh> I suspect it is hard to switch?
[20:55:44] <fragalot> so. desktop sized lathes, anyone? :P
[20:55:58] <andypugh> All the desktop lathes are equally rubbish.
[20:56:06] <andypugh> (amongst the new ones, anyway)
[20:56:18] <fragalot> andypugh: Well i'm looking for an "almost not rubbish" one
[20:56:19] <fragalot> :P
[20:56:26] <fragalot> andypugh: I don't see why it'd be hard to switch really
[20:56:52] <fragalot> if it'd also be another size, that's a different matter
[20:57:00] <andypugh> Well, it depends how much you manually generate radii by twiddling both handles at the same time.
[20:57:27] <fragalot> Ah, yeah. rarely... today actually,.. I failed.

[20:58:53] <fragalot> winged all of the dimensions as it's really only a prototype :P
[20:59:10] <skunkKandT> heat engine? or flame licker?
[20:59:19] <fragalot> skunkKandT: flame licker
[20:59:22] <skunkKandT> neat
[21:01:40] <fragalot> I just woke up this morning with the idea to make one that doesn't have a "complex" cam valve system
[21:02:18] <skunkKandT> magic?
[21:02:34] <fragalot> no, just a valve controlled by the piston itself
[21:02:57] -!-
psha has quit [Quit: Lost terminal]
[21:03:00] <skunkKandT> ah
[21:03:29] <andypugh> Like the little CO2 engines?
[21:03:49] <fragalot> when it's fully retracted, it's going to pull the valve into the closed position, when going back, air pressure will partially open the valve because it's just loose in the cylinder, and then hte piston pushes it fully open before it sucks the flame in again
[21:03:59] <fragalot> it made sense in my dream >.>
[21:04:45] <fragalot> I might have to remake either the cylinder or the piston though.. the fit is snug, but not quite as snug as i'd like it to be
[21:05:35] <fragalot> couldn't find the right tool to get up into the cylinder so it's just drilled & lapped.. not quite perfect :<

[21:26:57] <n0b> andypugh, i'm just trying to jog the spindle around the table.... at the same height... but at each point i jog to, i want emc2 to stop, and wait for me to click okay/continue... and then it will jog to the next point and stop
[21:27:08] <n0b> and wait for a click okay
[21:27:11] <n0b> repeat
[21:27:57] <andypugh> When you say "Jog" you don't mean "jog" do you?
[21:28:31] <n0b> it's not gonna be cutting...
[21:29:01] <andypugh> Do you want to pause a G-code program until you press a button? If so, then use M0.
[21:29:13] <andypugh> http://www.linuxcnc.org/docview/html/gcode_main.html#sub:M0,-M1,-M2,
[21:29:43] <andypugh> "Jogging" is when you move the machine using hand controls.
[21:29:54] <n0b> oic
[21:30:01] <n0b> :D
[21:30:59] <andypugh> You need to use "S" to restart after M0
[21:31:07] <andypugh> (Other keys might work too)
[21:31:20] <n0b> that's what i'm afraid of :p
[21:31:25] <n0b> random keystroke
[21:37:44] <andypugh> Try it and see.
[21:38:26] <n0b> I'd try the trial error method, but I'm not at home... :D
