[13:18:31] <cradek> those paths don't exist
[13:18:41] <pilla_> hmmmh
[13:18:42] <cradek> are you really running breezy?
[13:18:51] <cradek> what have you done to get to this point?
[13:18:52] <pilla_> lucid
[13:19:02] <pilla_> I followed the tutorial on the site xD
[13:19:02] <cradek> well then those lines are totally wrong.
[13:19:48] <cradek> go to www.linuxcnc.org, click download, click basic installation
[13:20:19] <cradek> you can use that cd image, or you can use the lucid-install script further down on the page
[13:20:50] <cradek> whatever you found is really outdated (breezy is from 2005). if you share the URL maybe someone can fix or remove it.
[13:21:02] <cradek> bbl.

[13:22:51] <cradek> no, you didn't, because it doesn't point you to a breezy repository that doesn't exist
[13:23:28] <cradek> I just checked
http://linuxcnc.org/install-scripts/lucid/linuxcnc-install.sh
[13:23:53] <cradek> there is nothing breezy-era on this page

[17:27:35] <RussianKid> it was a thread about smoothstepper boards being available in the uk, and about how it was a huge improvement for a generic NEMA stepper DIY CNC
[17:27:58] <skunkworks> the linux verion is just a fancy gui that feed info to a motion box. (sam for the most part on the windows side)
[17:28:09] <skunkworks> they just can't do realtime very well.
[17:28:13] <RussianKid> and its not really, because the smoothstepper primarily provides much higher step rates, which almost never is a limiting factor
[17:28:46] <RussianKid> so you're spending like a lot of money on hardware which doesn't really give anything, and it was blatantly misleading, and they made handwaving statements like 'an improvement in accuracy was noted on all machines'
[17:29:05] <skunkworks> yikes
[17:29:25] <skunkworks> because the mach tp and step generation isn't perfect....
[17:29:43] <jdh> looks like the new stuff offloads all step gen to HW
[17:30:05] <jdh> much like many here do with mesa
[17:30:37] <skunkworks> jdh, not exactly
[17:31:11] <RussianKid> the thing that bothers me the most is that there is a large cluster of people who refuse to believe that mach's measure distance and divide by steps wizard makes your machine as accurate as the instrument you used to measure the distance
[17:31:52] <skunkworks> mach requires a outboard motion cotrol that gets fed high level command and the motion happens in the magic box

[17:32:30] <jdh> yeah, still, all the step gen is done in hardware (and some more)
[17:32:36] <skunkworks> So you are stuck with the 'realtime' things that that motion device manufacuter builds in.
[17:32:49] <jdh> it's drip feeding a hw control

[17:34:08] <skunkworks> so any realtime things (like rigid tapping or such) added to linuxcnc are available to all devices. (that is why you can rigid tap with just printer port hardware if you want to)
[17:34:25] <RussianKid> wait will the HW motion box be compulsary, or will there still be the option to output via parallel port?
[17:35:03] <andypugh> p-port is only going to be available in the Pro version
[17:35:08] <skunkworks> sounds like pro will have the printer port still (although limited to 32bit)
[17:35:20] <skunkworks> and art doesn't know how long...
[17:35:34] <RussianKid> so theyve split not just windows/linux but also normal/pro? that's a lot of versions to maintain
[17:35:52] <skunkworks> but the lite version will require a external motion device.. (which puts it in the 299 price range so far)
[17:35:56] <andypugh> tbf it isn't Mach's fault if 64-bit wondows hides the paarport
[17:36:12] <FinboySlick> RussianKid: Maybe they wrote it in .Net ;)
[17:36:22] <skunkworks> which you can get a mesa setup that is a lot lot more flexible for $200
[17:38:22] <RussianKid> tl;dr mach failed to get better
[17:38:27] <gmouer> mesa boards and linuxcnc is a fair amount cheaper than mach and a smoothstepper or similar, and much more powerfull , done both

[17:39:23] <skunkworks> gmouer, glad you converted!

[17:39:45] <skunkworks> (I think I have read your post on the mach yahoo groups) correct?
[17:40:19] <gmouer> yes, and home shop machinist too just recently (Sparky_NY)
[17:40:29] <skunkworks> ah - Hi
[17:40:32] <skunkworks> :)
[17:40:45] <skunkworks> so when is the mill conversion starting?
[17:41:25] <RussianKid> >lowering the complications
[17:41:25] <RussianKid> >all about simple
[17:41:25] <RussianKid> it reminds me of that line on apple's site 'effortlessly adjust exposure, saturation and contrast with your mouse. You don't even need to know what those things are. Just click and drag until everything looks picture perfect'
[17:41:27] <gmouer> well, the mill actually works decent under mach so there is no big hurry, but its going to happen for sure
[17:41:36] <skunkworks> heh
[17:41:52] <gmouer> I am spoiled now with linuxcnc
[17:43:11] <gmouer> my 14x40 lathe gets reretrofitted from mach first, thats the next project, a simple one but the reason I went linuxcnc
[17:43:23] <gmouer> got fed up LOL
[17:43:42] <andypugh> RussianKid: Actually, that Apple idea sounds quite reasonable.
[17:44:16] <skunkworks> gmouer, Once you get buy the 'oh my god it is linux!' it isn't so bad :)
[17:44:25] <RussianKid> it's the way they word it. I mean you're editing a picture, why WOULD you want to know what exposure, saturation and contrast are?
[17:44:33] <andypugh> I didn't have that barrier, I was on a Mac.

[17:45:31] <FinboySlick> andypugh: But Macs drain away your testosterone...
[17:45:36] <andypugh> I slightly disagree. You dopn't need to know what they are called to be able to judge the effect.
[17:45:42] <Connor> One issue I have with Mach is it's interface is just dog ugly and overly complicated
[17:45:53] <andypugh> FinboySlick: I have no practiacl use for testosterone anyway.
[17:46:05] <RussianKid> there are lots of screensets for it, and its not a huge deal to write your own either
[17:46:22] <gmouer> yea, but that is also machs biggest strength, it interface gui and the ability to customize it easily

[17:46:47] <andypugh> But you can create a custom GUI for LinuxCNC with only a few weeks solid work :-)
[17:47:27] <RussianKid> i've been wanting to change a fair bit of axis for ages, it's on my to do list
[17:47:28] <Jymmm\AE> FinboySlick: Did you see the bald guy in the photo?

[17:49:51] <jthornton> there is even a tutorial for creating your own GUI for linuxcnc
[17:50:01] <andypugh> Actually, there is supposedly a link between testosterone and baldness. SO if there _is_ a Mac/baldness anti-correlation, perhaps FinboySlick has a point.
[17:50:06] <RussianKid> there are the source files though
[17:50:54] * FinboySlick amused.
[17:51:26] <andypugh> Anyway, I am not babe-Andy (she's some sort of artist) so what was the question?
[17:53:14] <FinboySlick> andypugh: Metalurgical genius Andy... I was sort of trying to wrap my head around what the so called cold-tempering process does to steel. That is the technique of supercooling steel to supposedly remove internal stresses. I don't see how freezing material would do that.
[17:53:44] <FinboySlick> Or is it all gimicky pseudo-science?
[17:54:21] <andypugh> I am not 100% convinced that it does what they say it does.
[17:54:22] <RussianKid> I got a sheet of alu recently that said stress relieved by stretching. I've not read up on it but it doesn't make sense to me how stretching can remove stress either.
[17:54:40] <andypugh> It _will_ tend to reduce retained austenite.
[17:55:06] <andypugh> But that retained austenite will convert to martensite on transformation.
[17:56:52] <andypugh> Another possible effect is that if there are thermal stresses caused by shrinkage from the high forming temperaure, then going much colder will increase those stresses, possibly past the plastic limit. Then when you warm up again, they are gone.
[17:57:34] <FinboySlick> OK, so it could potentially be useful in already tempered material then.
[17:58:42] <andypugh> Look at it another way. If the part has thermal streses at room temperature, then they ought to be less at a higher temperature. Cryo-cooling makes -192C the new "room temperature" and the operating temperature is now relatively hot.
[17:59:36] <FinboySlick> andypugh: Yeah, that last bit I had understood.
[17:59:51] <FinboySlick> I had to wiki austentite and martensite though ;)
[18:01:32] <andypugh> Austenite is what steel is when it is hot. It then turns to Ferrite (tough, soft) and Martensite (brittle, hard) when you cool it. How you cool it, and the metal composition, affect the relative ratios of ferrite and martensite.
[18:05:03] <FinboySlick> I'm smarter now :)
[18:05:08] <FinboySlick> Thanks.
[18:06:04] <Jymmm\AE> Anyone familiar with thin (=<0.015") SS sheet grades? I need to BOW a 6"x12" sheet around a 4" diameter pipe and have it spring/flex/return back to it's flat state as much as possible. I'm tried 316, but it seems to bend more than it bows. 412 seems too stiff.
[18:07:28] <Jymmm\AE> I have some 312/314 hybrid samples on the way. but still not sure that's going to do it.
[18:09:29] <Jymmm\AE> The 0.010" aluminum roof flashing you can get from home depot/lowes seems to have the right characteristics, but need stainless instead.
[18:09:47] <andypugh> You probably need something cold-rolled. A spring steel grade

[18:13:29] <Jymmm\AE> andypugh: Says "nickel" is the key component...
http://en.wikipedia.org/wiki/Spring_steel
[18:14:05] <andypugh> Low nicket 316 is what Lee Steel Strip used.
[18:14:25] <Jymmm\AE> Lee Steel?
[18:14:41] <andypugh> Not the same as Lee Spring
[18:15:38] <andypugh> Merged with Avesta some time after I worked with them:
http://www.cisionwire.com/avesta-sheffield/r/avesta-sheffield-purchase-of-lee-steel-strip-approved,e14095
[18:16:13] <andypugh> But, they used deliberately low-stability stainless steel and rolled it to massive hardness.
[18:16:21] <andypugh> (presumably they still do)
[18:16:36] <Jymmm\AE> andypugh: And what does that process accomplish?
[18:17:37] <andypugh> It gives the material a much harder yield stress. Effectively you need to bend it further than the rolling process did to reach the elastic limit.
[18:18:13] -!- gmouer has quit []
[18:18:50] <Jymmm\AE> and the yield stress makes it want to return to it's original flat self?

[18:20:08] <BHSPiMonkey> Could someone advise on the pros/cons between two stepper motors? (One has 1.8deg steps and max speed of 600rpm, other has 0.9deg and 300rpm)
[18:20:32] <BHSPiMonkey> In other words it looks like I could trade off speed for finer step resolution
[18:21:03] <BHSPiMonkey> Torque is pretty identical between the two

[18:29:21] <FinboySlick> BHSPiMonkey: How fast do you need the machine to move?
[18:30:39] <FinboySlick> If torque is similar and it'll move as fast as you need, I'd say go for the 0.9° version and save some of the disadvantages of microstepping.
[18:31:49] <pcw_home> Static torque may be the same but torque vs speed at a given drive power supply
[18:31:50] <pcw_home> voltage will drop off twice as fast for the .9 degree stepmotor.
[18:31:52] <pcw_home> so what FinboySlicksaid : how fast do you need to move?

[18:32:26] <BHSPiMonkey> I have no real needs; I'm diving into the CNC world by building a Shapeoko
[18:32:35] <BHSPiMonkey> Just for fun
[18:33:49] <BHSPiMonkey> Realistically, based on past discussion, it doesn't seem like the precision difference is *that* substantial in terms of actual results (feel free to challenge that claim)
[18:34:38] <BHSPiMonkey> So my impression is that the increased movement speed will be the "better" advantage to have
[18:35:11] <pcw_home> a 1.8 degree stepmotor with double the ustep ration may well perform better than a .9 degree motor (in terms of torque vs speed)
[18:37:17] <BHSPiMonkey> I appreciate the expertise

[18:38:03] <skunkworks> andypugh, I think mach is trying for the industrial cnc market...
[18:39:01] <pcw_home> This also depends on how close your loads are to stall torque. If you are running close to stall torque, more poles will beat a higher Ustep ratio (.9 degrees to peak torque vs 1.8 degrees)
[18:39:47] <BHSPiMonkey> pcw_home: does that basically come down to how tough the material is to chew through?
[18:40:13] <pcw_home> and the gearing and mass and accell
[18:40:19] <andypugh> Well, that is where the real money is. But can they offfer industrial levels of support?
[18:41:47] <BHSPiMonkey> pcw_home: I'm probably just going to be doing simple tasks with wood/mdf/acrylic
[18:42:16] log_ybon is now known as ybon
[18:42:48] <BHSPiMonkey> So far it feels like the speed is probably more immediately useful than the step resolution
[18:42:53] <skunkworks> andypugh, if all they are is a gui running galil or other motion boards.. maybe?

[22:48:39] <andypugh> LinuxCNC frequently is.
[22:49:19] <andypugh> What bugs me is that the filter at work considers "hackaday" to be a "related to hacking" and won't let me view it.
[22:49:29] <PCW> Not for a while though
[22:50:31] <PCW> yeah two different meanings of hack

[23:45:57] <Valen> ey pcw able to chat on work time for a minute?
[23:46:16] <PCW> Yes
[23:46:59] <Valen> I'm the guy who wants to use half an encoder again, any suggestions for how it'd work (other than badly)
[23:47:19] <Valen> IE how i'd get a count out of the card
[23:47:55] <Valen> or would it require changes to the firmware in the card?
[23:48:37] <PCW> I can hard wire a up/dpwn counter mode that takes the drive directions as motion direction (yes a firmware change)
[23:49:11] <PCW> But I honestly dont have a lot of hope it would work well enough
[23:49:57] <Valen> its for a prototype for a science experiment, people are going to be touching an array of little wheels and the wheels get driven a few mm
[23:50:18] <Valen> (6mm motors with 1000:1 gearboxes on them driving 8mm wheels)
[23:50:25] <andypugh> Valen: Use the software counters?
[23:50:55] <Valen> what are these software counters of which you speak?
[23:51:02] <andypugh> Sounds like there won't be a huge count rate?
[23:51:14] <andypugh> The HAL encoder component
[23:52:03] <andypugh> (I am not certain that it will help)
[23:52:42] <Valen> I spose i could look at doing it all in software
[23:52:50] <Valen> just poll a pin
[23:53:00] <Valen> I want it all to be as off the shelf as possible
[23:53:03] <JT-Shop> could this be similar to my winder example in hal?
[23:53:44] <JT-Shop> or is this just a MPG?
[23:53:50] <PCW> if you need them to hold position I dont think it will work If you only need to drive them approximately N counts
[23:53:52] <PCW> this way or that a non quadrature thing should work
[23:54:25] <andypugh> Can you describe the problem?
[23:54:26] <Valen> there should be no back drive, and .1 of a mm precision would be heaps
[23:54:39] <Valen> gimme a sec i'll stick some images up
[23:56:11] <JT-Shop> I'm amazed that I can still stand up after pedeling 12 miles through the woods
[23:56:18] <JT-Shop> pedaling
[23:56:38] <Valen> this is the overall thing

[23:57:18] <Valen> for scale the purple motors are 6mm diamiter
[23:57:45] <Valen> there is going to be an array of 49 of these things that you can rest your hand on
[23:59:03] <PCW> all they do is rotate a little?
[23:59:04] <andypugh> Is there a really good reason not to use a quadrature sensor?
[23:59:19] <Valen> the science people want to be able to drive each individual pin up into contact with your hand, (set the position) then drive back down, and up to that point again. then rotate the wheel when its in contact with the skin
[23:59:38] <JT-Shop> 149 inputs for quad?
