[00:16:35] <PetefromTn> andypugh: Hey man just about how long did that part for instance take to code up and how long did the actual program run on your machine?

[00:28:55] <andypugh> PetefromTn: Well, the part I made today was http://imagebin.org/256731
[00:29:41] <andypugh> And it was pretty much all I got done today (bank holiday, no work) but then I wasn't full-on at it and spent a fair bit of time trying to replace the chain on my bike.
[00:30:13] <PetefromTn> braggart LOL
[00:31:01] -!- slifty has quit [Quit: Leaving...]
[00:31:16] <PetefromTn> what did you use to draw that part?
[00:31:35] <andypugh> The CAD has been going on for weeks while I work out other things round it. But the actual CAM was probably a couple of hours (of which half was waiting for PyCAM to produce the toolpaths) and total machining time was 4 hours or so (you can take big cuts with the foam)
[00:31:44] <andypugh> Autodesk Inventor.
[00:32:34] <andypugh> But I get a free home license as a side-effect of my job. It's pretty expensive to buy.
[00:33:25] -!- Felix29 has quit [Ping timeout: 276 seconds]
[00:33:28] <PetefromTn> Oh so that was foam then? Got a picture of that part? How does it work in almuminum?
[00:36:28] -!- tjtr33 [tjtr33!~tjtr33@75-150-145-37-Philadelphia.hfc.comcastbusiness.net] has joined #linuxcnc
[00:36:49] <andypugh> No pictures of the part, and it's getting late here, so I am rather more likely to go to bed than the garage.
[00:37:33] <andypugh> It would work perfectly well in Alumnium, if my milling machine was up to the task. It would take a whole lot longer, though.
[00:39:45] <PetefromTn> My deal is Honestly I don't do much 3d at all but I WOULD like the ability so a FREE program is highly desirable until I can ante up for something more commercial in nature.

[01:07:01] -!- FinboySlick [FinboySlick!~shark@squal.net] has joined #linuxcnc
[01:07:11] <andypugh> PetefromTn: Yes, that is pretty much what PyCAM is doing for me. I generally use 2.5D.
[01:08:15] <Connor> What did I miss? Had a few issues with my ISP
[01:08:17] <PetefromTn> It is a shame it is limited as you say but apparently you are making 3d parts successfully so how bad could it be right...
[01:08:24] <andypugh> I am also hopeful that pyCAM can be improved. However, there are several other things out there, that are also free. I just haven't tried them yet.
[01:08:41] <PetefromTn> Oh man you really missed out on some amazing stuff sorry LOL
[01:09:08] <L84Supper> ... and thats how you turn lead into Gold
[01:09:22] <PetefromTn> yes exactly....Can't wait to try it.
[01:10:07] <PetefromTn> any of you guys using that FSwizard?
[01:10:26] <andypugh> ?
[01:10:44] <PetefromTn> or rather HSMadvisor now...
[01:10:55] <L84Supper> more people seem to be interested in adding 4-5 axis support to PyCam than any other open CAM tool
[01:12:00] <PetefromTn> you using it?
[01:12:20] <andypugh> I would have thought making it produce a toolpath in less than a day would be a better enhancement. (The push-cutter and drop-cutter grid algorithms work fine, but do spend an awful lot of time cutting air)
[01:12:47] <andypugh> The contouring algorithms ought to be better, and give a better finish, but are unusably slow.
[01:13:46] <PetefromTn> does it do waterline and linear etc 3d paths?
[01:13:48] <generic_nick|2> wow, mastercam does it in seconds
[01:14:02] <PetefromTn> how much did you pay for mastercam?
[01:14:15] <L84Supper> we figured speeding up the toolpath generation would come with refactoring PyCam
[01:14:35] <L84Supper> it just needs a makeover
[01:14:49] <andypugh> The Waterline algorithms are the slow ones. I suspect it spends too long considering the tool geometry even in cases where the tool chape is very simple.
[01:15:30] <PetefromTn> aw that sucks...
[01:16:00] <L84Supper> people have been talking about using voxels and the GPU
[01:16:00] <andypugh> L84Supper: When I learn Python, and have infinite spare time, looking at the toolpath algorithms in PyCAM is on my list...
[01:16:34] <andypugh> Yes, I did find myself thinking about voxels while watching the machine do its thing.
[01:16:44] <L84Supper> lots of talk right now and interest, maybe things will get going over the summer
[01:17:27] <L84Supper> having a couple funded devs to work on it will also help
[01:17:30] <FinboySlick> I think Minecraft is responsible for all the voxel hype ;)
[01:17:32] <andypugh> One idea that occurred to me was a simple G-code postprocessor, that scans through G-code and subtracts voxels, then trims any path that is only cutting air.
[01:17:57] <L84Supper> voxelpress is another
[01:18:38] <andypugh> I was thinking about voxels in 1998. I worked in a medical imaging research group.
[01:18:51] <L84Supper> yeah, it's not new
[01:19:22] <L84Supper> image processing and MRI
[01:19:23] <andypugh> My thinking was that building an STL of the part-machined shape was likely to be wasteful.
[01:19:57] <andypugh> Not that Voxels are even slightly efficient.
[01:20:13] <L84Supper> it would be nice to come to some consensus on the approach
[01:20:47] <L84Supper> http://voxelpress.org/rasterization_demo.html
[01:20:50] <tjtr33> reading that paper on jitter made me think, someone should invite Mssrs Proctor & Shackleford to the Witchita get-together
[01:21:29] <andypugh> I need to work out how the current algorithms work. I did have some discussion with sumpfralle on the subject.
[01:22:52] <andypugh> For a cylindrical cutter creating a waterline from STL is very fast and easy. It is when you add a tool radius that it gets hard. And if you have to worry about undercuts, then it gets harder again.
[01:23:48] <L84Supper> after looking over Slic3r, skeinforge, PyCam and Heeks there needs to be some serious effort into making useful CAM tools that aren't >$10K
[01:24:41] <L84Supper> CAM for cutting as well as additive manufacturing
[01:25:03] <andypugh> Anyway, time I was gone.
[01:25:11] -!- andypugh has quit [Quit: andypugh]
[01:25:17] <L84Supper> rather that CAM for cutting and another camp working on 3dp
[01:25:30] <tjtr33> L84Supper, did you see the Russian youtube toolChain tutorial on FreeCad->Heeks->Linuxcnc?
[01:25:56] <L84Supper> no, I'll have to check it out
[01:26:52] <L84Supper> the real missing piece is CAM for 3DP, even mastercam and NX CAM don't have anything for additive yet and Slic3r is a toy
[01:28:32] <L84Supper> http://www.youtube.com/watch?v=NP9YZwHbBE4 Freecad to Heekscnc to LinuxCNC Tutorial sounds Polish
[01:28:45] <Tecan> (NP9YZwHbBE4) "Freecad to Heekscnc to LinuxCNC Tutorial" by "Gab Trzyde" is "Tech" - Length: 0:07:57
[01:28:57] <tjtr33> yes it does, dunno where i got the russian idea
[01:35:31] <tjtr33> and i didnt see why he'd deck the top with a path bounded by the shape, or how he'd hold the thing while he ran a perimeter cut
[01:35:50] <tjtr33> but its 'exemplary' i 'spose

[02:45:05] <L84Supper> bob interface?
[02:48:12] <ssi> breakout board
[02:48:17] <ssi> a bbbbb if you will
[02:48:31] <ssi> first one will be pretty simple
[02:48:39] <ssi> a bare bones beaglebone black breakout board
[02:49:54] <L84Supper> most of the GPIO is shared

[02:58:17] <pcw_home> 1K $22.52 or so for 1Ghz
[02:58:44] <ssi> off by an order of magnitude, dang
[02:58:58] <L84Supper> ~$14 in China
[02:59:17] <ssi> L84Supper: for the ti part? or a clone
[02:59:24] <L84Supper> TI
[03:04:31] <L84Supper> http://circuitco.com/support/index.php?title=BeagleBoneBlack#LATEST_PRODUCTION_FILES_.28A5A.29
[03:05:12] <L84Supper> it would only take a few days to fix this and bump it to 1GB DDR3
[03:05:39] <ssi> fix what?
[03:07:14] <L84Supper> better board layout and 1GB of RAM
[03:07:15] -!- Keknom has quit [Quit: Leaving.]
[03:07:40] <ssi> do it
[03:07:55] <ssi> what would you change about the layout besides putting the headers on bottom?
[03:09:37] <L84Supper> depends on who it's for
[03:10:06] <eric_unterhausen> how does it hurt that the headers are upside-down?
[03:11:01] <L84Supper> cheapskates just want it for as low a price as possible, they don't care if it has handlebars and a saddle mounted in the center
[03:11:30] <ssi> not an invalid strategy
[03:11:57] <ssi> and suits my needs too... if you make the thing $200, there's little point in working toward replacing $200 PCs
[03:12:30] <eric_unterhausen> depends on how capable the thing ends up being
[03:12:56] <eric_unterhausen> if it works really well, it would probably be worth investing some $ in it
[03:13:17] <ssi> it already works pretty well, he's just grousing because someone else is making the cash :)
[03:14:23] <L84Supper> SODIMM connector or PC-Card type connector on one edge vs connectors everywhere
[03:14:49] <pcw_home> I doubt if anyone is making much cash on the Beaglebone (except TI getting developer mindshare for cheap)
[03:15:08] <L84Supper> it's the 512MB that gets me, for a few $$ more it could have 1GB
[03:15:08] <ssi> that'd certainly make it nicer for fitting into a system, but not great for experimenting
[03:15:36] <ssi> pcw_home: I'm sure you're right about that... especially if the soc is half the retail price
[03:15:49] <ssi> although I've also heard rumblings that TI is subsidizing some of it
[03:15:56] <ssi> exactly for the mindshare reason
[03:16:08] <L84Supper> the cpu could be $6
[03:16:13] <pcw_home> Yep cheap advertising
[03:16:26] <eric_unterhausen> funny thing is, people were whining about the price
[03:16:39] <pcw_home> Not $6 if you or I buy it
[03:16:53] <eric_unterhausen> "olimex blah blah"
[03:17:00] <ssi> eric_unterhausen: it's hard to justify spending much more than $50 on a dev board if you're harry hacker with no clue what to do with it
[03:17:11] <L84Supper> yeah, why i don't bother anymore, the RPi proved that open source doesn't really matter, just price
[03:17:37] <ssi> rpi is a joke
[03:17:59] <pcw_home> I wonder how munkie is doing with his DMA stepgen on RPI
[03:18:03] <ssi> TI is handling this much better than BCM did the rpi
[03:18:20] <eric_unterhausen> raspi is exactly the right price for people to buy it, put it on their desk and later throw it away
[03:18:32] <ssi> eric_unterhausen: heh you got that right
[03:18:47] <ssi> although it's "buy it, put it on their desk, try to find docs on how to do something with it other than write python, throw it away"
[03:18:48] <pcw_home> BCM is shitty to deal with (TI used to be the same)
[03:19:52] <ssi> I had one simple little thing I wanted to do with the rpi
[03:19:54] <ssi> I2S out to a dac
[03:20:04] <ssi> and it's not possible without airwiring to traces on the board
[03:20:08] <eric_unterhausen> BCM is targeting high-volume customers and doesn't care about the rest of us
[03:20:23] <ssi> and even then, you have to write drivers for an undocumented device
[03:20:28] <ssi> or rather, NDA documented device
[03:20:55] <ssi> eric_unterhausen: that's the typical corporate strategy, but then they have no business being involved in a hacker project like the rpi
[03:21:03] <ssi> and I guess that's not really bcm's fault, it's the rpi foundation's fault
[03:21:06] <eric_unterhausen> it's just amazing to me what is under nda nowadays
[03:21:13] <ssi> but they have these lofty academic goals about education and crap
[03:21:20] <L84Supper> the am3359 is ~$14 out the backdoor, 2x the A10
[03:21:37] <eric_unterhausen> bcm makes some neat stuff, don't understand the stupidness about nda
[03:21:41] <pcw_home> Only nifty thing about the BCM chip is the stacked RAM
[03:22:15] <L84Supper> BCM evolved out of military silicon
[03:22:26] <L84Supper> they still have that mentality
[03:22:35] <L84Supper> everything is under NDA
[03:33:10] <L84Supper> i.MX6 Solo 1GHz: ~$11 @ 10k+ i.MX6 Dual 1GHz: ~$23 @ 1k+ i.MX6 Dual lite: ~$16 @ 1k+
[03:34:27] <L84Supper> http://pastebin.ca/2375279 more i.mx6 pricing
[03:35:08] <L84Supper> the quad core sells for around the same price as the am3359

[03:40:41] <L84Supper> I saw that
[03:40:52] <ssi> was thinking it could be interesting to try writing drivers to run a RAMPS shield on it
[03:40:55] <ssi> since it's pin compatible
[03:41:37] <zultron> Hey L84Supper, I've been hacking on PyCAM, right now just to fix the broken task settings persistence.
[03:41:46] <zultron> If you start working on the TPGs, let me know.
[03:42:34] <L84Supper> zultron: people have been mostly complaining about the slow path generation
[03:42:46] <zultron> I was looking at integrating some of Anders Wallin's work, and it turns out that someone's already started doing some of that maybe; there's an opencamlib branch in SF git.
[03:42:52] <zultron> Yeah, it's very slow.
[03:43:27] <zultron> Still no TPGs for 5-axis, but I've been looking at some journal articles. Just musing for now, not sure whether that'll turn into actual effort or not.
[03:44:09] <zultron> I'd also like to integrate cut simulation; Anders has a library for that, too.

[03:45:50] <L84Supper> ssi: whats the link between the imx6 and the sam3?
[03:46:01] <ssi> I think it's just a uart
[03:49:02] <L84Supper> I was surprised by the popularity of the arduinos, I could never even stand the name :)
[03:49:58] <eric_unterhausen> hard to understand?
[03:50:17] <ssi> L84Supper: I used to be seriously into PIC programming, and the arduino stuff used to irk me too
[03:50:21] <ssi> but I got the fuck over it... they're convenient
[03:51:38] <L84Supper> $100 for the dual core board?
[03:51:40] <ssi> yea
[03:52:01] <L84Supper> $129 for the quad
[03:55:32] <L84Supper> SATA only on the 4-core version
[03:58:29] <ssi> oh there's sata? neat
[03:59:02] <eric_unterhausen> kickstarter has a lot of silly projects
[03:59:10] <ssi> yeah
[03:59:15] <ssi> I should know, one of them's mine :)
[03:59:26] <eric_unterhausen> amazing how much money is on there now
[03:59:39] <eric_unterhausen> I guess for the price of a raspi, you can be a backer
[04:00:04] <eric_unterhausen> with the advantage of no messy desk
[04:00:34] <ssi> the messy desk is the best part
[04:00:36] <L84Supper> heh, imx6 + RPi on the same board
[04:00:55] <L84Supper> with socket for arduino
[04:01:16] <eric_unterhausen> if socket == usb port, I'm in
[04:02:13] <L84Supper> if people would actually cooperate the SOC on SODIMM or similar with standard breakout boards
[04:03:09] <L84Supper> but OEM's don't want that
[04:03:22] <ssi> http://www.kickstarter.com/projects/crystalfontz/cfa-10036-open-hackable-linux-arm-embedded-gpio-mo
[04:03:25] <ssi> people don't want that
[04:03:26] <ssi> I backed that one
[04:04:04] <L84Supper> i.mx28
[04:04:21] <eric_unterhausen> i remember that
[04:04:55] <eric_unterhausen> the sodimm thing always seems to involve $$$ for some reason
[04:04:57] <L84Supper> but a a10, a31, imx6, and similar 4-8 core arm's as they evolve
[04:05:49] <L84Supper> I tried to work with the EOMA-68 stuff but the ringleader was too difficult to work with
[04:05:54] <ssi> well like I said earlier, it's just not super hackerfriendly
[04:06:17] <ssi> at least with the headers on the beagle, I can airwire to it, or build a breadboard, or whatever
[04:06:28] <ssi> sodimm requires spinning a board and sourcing connectors at the very least
[04:06:38] <L84Supper> the beaglebone could be a $30 sodimm module
[04:07:06] <ssi> L84Supper: I could see a use for having that if it's otherwise exactly compatible
[04:07:16] <ssi> then designing a nice machine control board with a sodimm connector on it
[04:07:30] <L84Supper> if the sodimm could be standardized
[04:07:59] <L84Supper> and then have several IO boards
[04:09:16] <L84Supper> laptop, tablet, kitchen sink, machine controller, etc etc
[04:09:53] <pcw_home> some I/O can be standardised betweens SOCs (USB,serial,I2C, SPI, MDIO,MMI.GMII.GPIO,GPMC etc)
[04:10:00] <L84Supper> reusing the PC-card form factor isn't a bad idea either
[04:10:53] <pcw_home> I like SODIMMs better though
[04:12:07] <ssi> yeah probably more convenient for embedded boards

[04:16:24] <L84Supper> only a few ARM soc vendors would actually sell parts at <1M pcs
[04:16:54] <L84Supper> many of those soc's never made it past the dev board stage and into any production
[04:17:30] <L84Supper> even fewer had open Linux support, many had Linux support only under NDA
[04:19:56] <ssi> what were you evaluating them for?
[04:20:39] <L84Supper> making an open standard soc card form factor
[04:21:19] <L84Supper> making the cpu cards and also the IO boards
[04:24:51] <L84Supper> but most OEM's don't want anything swap-able or upgrade-able, it should die right after the warranty is up and be worthless after
[04:25:18] <fiesh> I'm sorry if this is not really concerning linuxcnc directly, but I figured this might be a good place to ask since people are knowledgable and open. I'm trying to predict the runtime of certain G-code on certain machins (actually controlled by a Siemens Sinumerik), but I'm not sure how this is handled: if I have say a G02 command of certain length and radius, and the speed and absolute value of the acceleration are limited on this
[04:25:24] <fiesh> "segment", plus there are limitations on the acceleration (and jerk, but that wouldn't really matter) and speed of the individual axes, what is the trajectory? Is it somehow well-defined, does it depend on the controller, or on the people who programmed it? Can I somehow predict it?
[04:26:39] <ssi> it should be able to be known by the machine controller
[04:26:57] <fiesh> (Of course this question applies to G01 command to, but I suppose it's safe to assume the optimization problem on those is actually solved correctly, since it's mathematically simple. But on non-straight curves it's different, and I don't want to solve it numerically optimal if that's not how it's done anyway)
[04:26:58] <ssi> it's specific to the acceleration and velocity limits of the machine, which are likely unknown by the programmer
[04:27:26] <fiesh> I actually do know those limits, and will leave them adjustable in my implementation anyway
[04:28:04] <ssi> if you're trying to implement that prediction yourself, and you know the accel and velocity of each segment, I don't see why you couldn't predict it
[04:28:14] <ssi> just remember to account for decel at the end of moves if it will exist
[04:28:44] <fiesh> yes, but the underlying optimization problem is not easy, in fact to solve it correctly you seem to have to take into account the whole NC-program at once
[04:28:45] <ssi> (some machines, like plasma for instance, don't decel, and round corners instead)
[04:28:56] <fiesh> so I was wondering if that's actually what the controller does, seems quite involved a solution
[04:29:23] <eric_unterhausen> not linuxcnc, which is a matter of annoying discussion
[04:29:53] <fiesh> ok, can somebody point me into how it's handled in linuxcnc?
[04:29:59] <eric_unterhausen> linuxcnc can stop at the end of every step, so lookahead is strictly limited
[04:30:13] <fiesh> "can" or "must"?
[04:30:15] <ssi> eric_unterhausen: I was afraid of that
[04:30:21] <ssi> "must be able to"
[04:30:24] <fiesh> oh
[04:30:28] <fiesh> and it always does?
[04:31:05] <eric_unterhausen> no, but it certainly affects the speed of operation
[04:31:18] <ssi> and QUALITY of operation for some applications
[04:31:29] <fiesh> is there a paper online that describes linuxcnc's behavior?
[04:31:36] <eric_unterhausen> I think if we could figure out how to change that it probably would be good
[04:31:37] <ssi> plasma cutting with lots of small segments is very much adversely affected by exact-path planning
[04:31:57] <eric_unterhausen> but it is a very complex issue
[04:32:36] <eric_unterhausen> better than a paper, there is source :)
[04:32:41] <fiesh> in general, the only solution seems to do it numerically, and yes, it can get pretty involved
[04:33:01] <fiesh> hehe, do you have a link? I'd really appreciate that
[04:33:02] <eric_unterhausen> well, people want "run from line"
[04:33:11] <fiesh> "run from line"?
[04:33:16] <ssi> I've never had good luck with run from line
[04:34:11] <eric_unterhausen> I don't know if that is the only issue, as I mentioned before, I find the path planning discussions to be annoying
[04:34:22] <ssi> haha
[04:34:32] <fiesh> oh I'm sorry, I didn't know this was a longstanding issue
[04:34:59] <eric_unterhausen> commercial controls all use some form of multi-line lookahead from what I can tell
[04:35:04] <fiesh> but I felt it fairly complex and wondered if actual controllers really solve it optimally, seems not then I suppose
[04:35:18] <eric_unterhausen> which introduces non-deterministic behavior in many cases
[04:35:26] <fiesh> it does? how so?
[04:35:53] <eric_unterhausen> if you are optimizing over multiple lines, then where are you if you stop?
[04:36:14] <fiesh> oh, well if you really want to optimize, you should consider the whole trajectory at once, of the full program
[04:36:44] <eric_unterhausen> that's not how machines are used apparently
[04:37:04] <ssi> there are historical reasons for that
[04:37:26] <ssi> machines until relatively recently couldn't even hold the full program in ram at once
[04:37:31] <fiesh> I suppose in earlier times, hardware was much too limited to even get close to solving it properly
[04:37:34] <fiesh> yes
[04:37:44] <ssi> I have a machine in the basement that ran off tape
[04:37:51] <ssi> PUNCH tape
[04:37:52] <ssi> D:
[04:37:58] <eric_unterhausen> love that punch tape
[04:38:08] <eric_unterhausen> edit with a razor blade
[04:38:33] <fiesh> heh I suppose it doesn't solve the full variatonal problem at once ;)
[04:38:34] <ssi> but even today, programs can be hundreds of thousands of lines
[04:38:43] <eric_unterhausen> linuxcnc is essentially a fancy drip feed system
[04:39:23] <fiesh> ssi: which would be a tiny problem for a modern computer

[04:56:20] <ssi> mhaberler: morn :)
[04:57:04] <mhaberler> buon giorno
[04:57:33] <mhaberler> let me know when I should start to break your driver ;)
[04:57:44] <ssi> soon, very soon
[04:57:49] <mhaberler> ah
[04:57:50] <ssi> elbows deep in gdb at the moment
[04:58:01] <ssi> in fact, let me check in what I have so you can start to criticize it :D
[04:58:08] <mhaberler> got the hang of debugging with rtapi_app?
[04:58:20] <mhaberler> actually you can trap on the thread function as well
[04:58:20] <ssi> more or less
[04:58:37] <ssi> it's blowing up in init
[04:58:41] <ssi> I have two strategies
[04:58:49] <ssi> one is let it run with no breakpoint and segfault, then backtrace
[04:59:03] <ssi> the other is to set a breakpoint on a particular line and see what everything's set to :D
[04:59:35] <mhaberler> one) is a standard QA method ;)
[05:00:29] <ssi> code's pushed, have at it
[05:00:37] <ssi> it's not as clean as I'd like
[05:01:29] -!- slifty has quit [Quit: Leaving...]
[05:01:29] <mhaberler> is it built automatically or is there a make fragment somewhere?
[05:01:43] <ssi> it's in the makefile, it should build with the rest of it
[05:02:00] <mhaberler> oh, src/Makefile then I assume
[05:02:03] <ssi> yes
[05:02:13] <ssi> I added it alongside some of the beagle/rpi stuff that was already there
[05:02:17] <ssi> think the beagle stuff was commented out
[05:04:27] <mhaberler> what would more than one port number mean? I guess this is a singleton driver?
[05:05:23] <ssi> initially I was thinking that it'd have two ports
[05:05:26] <ssi> one for P8, one for P9
[05:05:35] <mhaberler> ah I see
[05:05:37] <mhaberler> ok
[05:05:37] <ssi> but I decided to scrap that and have it be single port
[05:05:46] <mhaberler> right
[05:05:51] <ssi> so you get bb_gpio.userledX
[05:05:57] <ssi> and bb_gpio.P8.in-XX
[05:05:58] <ssi> etc
[05:06:27] <ssi> you should be able to load with user_leds=0,1,2,3
[05:06:38] <mhaberler> ok, dont use perror or printf, use rtapi_print_msg()
[05:06:45] <ssi> yea
[05:06:53] <mhaberler> those are RT-safe and go the right log channels
[05:06:53] <ssi> there's an rtapi_print() in there, that's what you're seeing
[05:07:09] <ssi> because rtapi_print_msg() doesn't show up at low levels for me
[05:07:14] <ssi> wasn't sure how to set that log level
[05:07:52] <mhaberler> just saw a lone perror somewhere; I use rtapi_print_msg(level, "dsdsf %d", strerror(-erno))
[05:08:00] <mhaberler> make that %s
[05:08:13] <ssi> oh yeah there is a perror in there
[05:08:23] <ssi> holdover from my original userland test program
[05:08:36] <mhaberler> there's no guarantee a write to stdio fd's hits the logs
[05:08:43] <ssi> yea
[05:08:46] <mhaberler> anyway, minotr
[05:09:53] <ssi> fixed, will push momentarily
[05:09:59] <ssi> instrumenting the P9 mmaps
[05:10:18] <mhaberler> looks sensible
[05:10:51] <ssi> there's error handling in there to prevent silly things like trying to map ground pins or map the same pin as input and output
[05:11:08] <ssi> I added an extra field to the bb_gpio_pin structure called "claimed"
[05:11:17] <ssi> whenever something configures a pin, it marks it claimed
[05:11:28] <ssi> in the future we can maybe do that via shmem for inter-driver cooperation
[05:12:08] <mhaberler> not really needed in shmem ; I will use an external symbol
[05:12:15] <ssi> ah k
[05:12:26] <mhaberler> say gpio_bitmap and gpio_bitmap_size
[05:12:43] <mhaberler> just havent decided where to put it, probably tack onto rtapi
[05:13:33] <mhaberler> the collisions would be all within RT context which is a single address space (rtapi_app)
[05:15:41] <mhaberler> do you have a sensible map to init that with? maybe it should be a bone-fide rt module with init code & args for a certain board to set bitmap size and proper bts
[05:16:17] <ssi> take a look in beaglebone_gpio.h
[05:16:22] <mhaberler> yes, thats the way to do it, a module (no thread function; just inits and exports the sym
[05:16:24] <mhaberler> ok
[05:16:26] <ssi> that can change, but it was a convenient way to get started
[05:17:11] <ssi> the data in there is important for me to have somewhere thought... it contains the gpio port number, pin on that port, and control offset register for a given pin
[05:17:11] <mhaberler> yikes, inited data in a header ;)
[05:17:16] <ssi> yeah I know
[05:17:16] <mhaberler> ok, thats what I needed
[05:17:36] <ssi> the NULL in that structure gets pointed at a bb_gpio_port structure that gets inited in configure_gpio
[05:17:59] <ssi> you ask for a handful of pins, the first time it encounters one on gpio1, it asks for gpio1 to be configured
[05:18:03] <mhaberler> I think we'll do a gpio module which takes a board=[bbw,bbb,rpi etc] param and does the right thing
[05:18:15] <ssi> that mmaps the port space, and then it points the pin structure at the resulting gpio struct
[05:18:26] <ssi> that works
[05:18:31] <ssi> then there's symbols available to query this info
[05:18:35] <mhaberler> and that needs to be loaded before drivers reference it
[05:18:36] <mhaberler> right
[05:18:44] <ssi> also I think we're probably going to want to look at the device tree overlay for pinmuxing
[05:18:50] <ssi> that'd replace my configure_pin nonsense
[05:18:53] <mhaberler> so it cant be 'forgotten'
[05:19:10] <ssi> but I don't know yet how painful that'll be
[05:19:10] <mhaberler> once we understand it ;)
[05:19:14] <ssi> right :D
[05:19:16] <ssi> this is fine for now
[05:19:37] <ssi> overall, I'm super excited about the progress
[05:20:42] <ssi> #define GPIO1_START_ADDR 0x4804C000
[05:20:43] <ssi> #define GPIO2_START_ADDR 0x4804C000
[05:20:46] <ssi> well that certainly can't be right
[05:20:47] <ssi> hahah
[05:21:02] <mhaberler> maybe that gives a clue: http://hipstercircuits.com/enable-pwm-on-beaglebone-with-device-tree-overlays/
[05:21:27] <ssi> that's in my queue to study
[05:21:30] <mhaberler> yep, those addresses are a tad off
[05:21:33] <mhaberler> fair enough
[05:22:21] <mhaberler> ok, I'll look into this gpio_map stuff; it might be a few days because I'm in the middle of something else but definitely will do it, it already bugged me and thats a good driver
[05:22:49] <ssi> no problem
[05:23:31] <mhaberler> maybe there is a way to split this driver into a generic and a board specific part (or conditional); just to prevent copy&paste programming once the next board comes around
[05:23:57] <ssi> well with the header the way it is, it should be as simple as a different header
[05:24:05] <ssi> different register addresses
[05:24:09] <ssi> pin mappings
[05:24:53] <mhaberler> (I had looked into websockets and javascript for a json interface to HAL for web ui's, and the javascript experience is underwhelming - clearly shows the effect of crack consumption on the web 'programming community')
[05:25:30] <ssi> yeah that's not my favorite
[05:26:02] <ssi> my favorite development experience of late is Scala
[05:26:08] <ssi> it's a really interesting language
[05:26:35] <mhaberler> adding a new interpreter to linuxcnc gets 100 negative points ;)
[05:26:44] <mhaberler> actually we should dump at least one
[05:26:45] <ssi> hahah
[05:26:48] <mhaberler> (tcl)
[05:27:00] <ssi> that's ok, I can deal with python for userland stuff
[05:27:20] <mhaberler> I would like go but it's a bit early and I'd violate my own rule
[05:27:36] <ssi> which rule is that
[05:27:53] <mhaberler> read my lips: no new interpreters ;)
[05:28:10] <ssi> oh a minute ago it was just a point cost
[05:28:12] <mhaberler> looks like it's less of a dog relative to Python and more clever with threading and concurrency
[05:28:13] <ssi> now it's a mandate!
[05:28:29] <ssi> scala's not interpreted, fwiw
[05:28:34] <mhaberler> I said 'i'd like, but I wont' because of my rule..
[05:28:36] <ssi> it's compiled to bytecode; runs in jvm
[05:28:44] <mhaberler> never tried it
[05:28:55] <ssi> nearly pure-functional
[05:28:57] <mhaberler> jvm, thats 500- points
[05:29:01] <ssi> nahhh
[05:29:08] <ssi> jvm carries a lot of advantages
[05:29:12] <ssi> especially once you get past the java language
[05:29:24] <mhaberler> do you see the gun barrel over there
[05:29:58] <mhaberler> no really we need to get out deps, not add..
[05:30:10] <ssi> not interested in adding any of that to linuxcnc, I promise
[05:30:28] <ssi> just ruby :D
[05:30:37] <mhaberler> we have way too much tcl stuff in there which is essentially unmaintained, and I dont see talent or willing takers
[05:30:49] <ssi> yea no thanks
[05:30:53] <mhaberler> or butchers for that matter
[05:32:01] <mhaberler> anyway, will blinken them leds and let you know (you did bbb only I assume?)
[05:32:55] <ssi> yeah bbb only
[05:33:01] <ssi> but it shouldn't be too much effort to cross over
[05:33:06] <ssi> in fact it may work as is
[05:33:13] <ssi> I'm pretty sure the registers are the same
[05:33:18] <ssi> hey does this mean anything to you?

[05:33:37] <ssi> that address is the OE register for gpio0
[05:33:51] <ssi> well, the address of where it's mmaped into my space anyway
[05:36:24] <ssi> I suspect thats a "hey you can't have this pin" message
[05:36:35] <ssi> but I don't see any reason why i wouldn't be able to have that pin

[13:01:03] <carper64_lb> well yes there is that
[13:02:03] <Tom_itx> kids will start tearing out abs pipe and grinding it up for sale now instead of copper and backflow prevention valves
[13:02:08] <L84Supper> thats one of the main problems with GGG, having to go from ~$1/lb pellets to $15/lb filament
[13:02:33] <Tom_itx> the latest trend here is stealing the brass backflow prevention valves in commercial installs

[13:03:56] <L84Supper> stealing live transformers?
[13:03:57] <archivist> you could include the granule grinder in the machine so you could just use old plastic :)
[13:04:00] <Tom_itx> yup
[13:04:09] <Tom_itx> well the interconnecting wire
[13:04:26] <carper64_lb> copper from wind turbines here oh and from mobile fone masts
[13:04:44] <archivist> seen one set of pictures of dead man up a pole on top of the transformer
[13:04:55] <Tom_itx> they've gone thru the parks stealing the lighting wire as well

[13:08:05] <Tom_itx> pretty soon you will need a license to sell scrap
[13:08:11] <L84Supper> carper64_lb: well you can just use a micronozzle and photopolymers and print faster, higher res and with lower cost materials
[13:08:39] <archivist> Tom_itx, over here we have to show ID to take scrap in now
[13:09:54] <L84Supper> photopolymer raw materials cost is equal to PLA and ABS pellets, and only requires mixing and not extruding to a filament
[13:10:38] <L84Supper> the problem is patents, not tech hurdles
[13:11:44] <L84Supper> SLS is faster and higher res than GGG, and there is a wider range of materials as well
[13:12:22] <Tom_itx> not much different than the expendables in inkjet / laser printers

[14:38:17] <r00t4rd3d> http://www.liveleak.com/view?i=2c3_1367925333
[14:38:47] <Gigs-> I was in here for a few weeks a while back, mostly just forgot to rejoin, and my plans for CNC were postponed as well
[14:39:06] <Gigs-> I've gotten a lot better at manual machining though
[14:39:21] <Gigs-> probably for the best, without knowing how to do stuff manually CNC would have been harder
[14:40:04] <Gigs-> also I have a secret crush on 12L14
[14:40:11] <Gigs-> don't tell anyone
[14:40:26] <ssi> yeah that stuff rocks

[14:42:11] <Gigs-> I've been processing gun brass as a business lately, which has given me a lot of opportunities to machine things
[14:43:06] <jdh> what's gun brass?
[14:43:14] <Gigs-> like the fired hulls
[14:43:23] <Gigs-> getting them ready to be reused
[14:43:27] <archivist> which gun brass as there is more than one with gun in its name
[14:43:32] <jdh> oh, no gun in there
[14:43:51] <Gigs-> fired cartridges archivist
[14:44:02] <archivist> that's normal brass brass that can be drawn
[14:44:07] <Gigs-> they are 70/30 I believe but I don't actually machine those
[14:44:10] <carper64_lb> this is my orac project https://www.dropbox.com/sh/6mcv3ywgf1cefrh/fnSNBgcdQH
[14:44:11] <jdh> plain old ammo brass
[14:44:56] <jdh> what do you do, deprime/tumble?
[14:44:57] <archivist> gunmetal and naval brass now they are different
[14:45:12] <carper64_lb> its almost fiiinished just software now and thats 90% sorted
[14:45:25] <Gigs-> clean, deprime, swage primer pocket, resize, trim, reprime
[14:46:12] <jdh> I load handgun rounds. never resize/trim though
[14:46:27] <Gigs-> the decapping die resizes for you jdh
[14:46:35] <jdh> oh, that resize
[14:46:38] <Gigs-> it's a lot less effort to resize pistol though
[14:47:02] <jdh> yeah, I don't use lube either
[14:47:12] <Gigs-> I found the greatest lube...royal case and die
[14:47:19] <jdh> roll on?
[14:47:21] <Gigs-> if you ever need to swage or form anything, that stuff is great
[14:47:23] <Gigs-> spray
[14:47:45] <Gigs-> http://www.midwayusa.com/product/782240/sharp-shoot-r-royal-case-sizing-lube-5-oz-aerosol
[14:47:57] <Gigs-> I even use this stuff on the sliding surfaces on my press sometimes
[14:48:14] <Gigs-> it's way slicker than normal grease, but it doesn't last quite as long as grease
[14:48:38] <Gigs-> I'm not sure what in it, but it smells like cherry coke
[14:48:46] <jdh> I should get some 223 dies, but then more powders, primers, measuring, trimming... sounds like a pain.
[14:48:57] <Gigs-> yeah just buy my preprocessed brass :P
[14:49:08] <Gigs-> processing rifle brass is a lot more work than handgun

[14:51:02] <jdh> that's pretty cool
[14:51:07] <Gigs-> well I didn't build it from scratch, it's based on the PW autodrive

It seem that I can not find the reason why it does not work and halcmd shows the naming correct also. Any insight would be great http://pastebin.com/LJYMBpQQ
[15:41:03] <ssi> #######Error = stepgen.2.position-fb must not be named same as pin######
[15:41:04] <ssi> #net stepgen.2.position-fb axis.2.motor-pos-fb <= thcud.z-fb-out
[15:41:10] <ssi> you need a signal name before the pins
[15:41:23] -!- Bojangle1 [Bojangle1!~IlIIlIll@58-7-170-30.dyn.iinet.net.au] has joined #linuxcnc
[15:41:46] <chopper79> I tried that also but then it gives an error about can not add out as there is already an out
[15:41:48] <ssi> ####Error = testpin can not add OUT pin thcud.z-fb-out, it already has OUT pin stepgen.2.position-fb#######
[15:41:52] <chopper79> Let me try again though
[15:41:52] <ssi> ###
[15:41:55] <ssi> #net testpin stepgen.2.position-fb axis.2.motor-pos-fb <= thcud.z-fb-out
[15:41:57] <ssi> yeah
[15:41:57] <ssi> you're trying to net together two output pins and an input pin
[15:42:04] -!- Kup has quit [Read error: Connection reset by peer]
[15:42:24] <ssi> the stepgen has a position-fb output, and so does the thcud
[15:42:33] <ssi> you need to choose one or the other to give back to axis
[15:42:42] <ssi> probably the thcud.z-fb-out
[15:43:22] <chopper79> Yeah the thcud.z-fb-out is the one I would use, I pretty sure anyway.
[15:43:44] <ssi> so just:
[15:44:01] <ssi> net zpos-fb thcud.z-fb-out => axis.2.motor-pos-fb
[15:44:11] <ssi> in fact you have that already
[15:44:30] -!- Bojangles has quit [Ping timeout: 256 seconds]
[15:46:16] <chopper79> What about stepgen.2.position-fb though as it should be needed for when the thc is not active so I can jog correct?
[15:46:54] <ssi> that I don't know about
[15:46:58] <ssi> jthornton probably would know
[15:47:09] <ssi> I did see something about setting your Z ferror very high to allow for the thc
[15:48:17] <chopper79> I did remember reading that somewhere also, but I thought it was for the THC300 config
[15:48:28] <ssi> what thc are you using?
[15:48:51] <chopper79> Im trying an THC from eagle at this moment.
[15:49:00] <ssi> gotcha
[15:49:19] <chopper79> I have another setup I really like but it needs some work to make it function with my setups.
[15:49:21] <ssi> I have a plasma table that used to run mach3 that I just tore down to convert over to linuxcnc
[15:49:27] <ssi> it has an LCTHC on it
[15:49:46] <ssi> if it gives me any trouble, I'll likely scrap it and get the mesa THCAD
[15:50:57] <chopper79> I have a mesa setup, but need to do some work to make it function with my setup. One day it will be operational as I really enjoyed messing with the mesa equipment.
[15:51:42] <ssi> yeah it's worth it
[15:51:44] <chopper79> for now though I will just use the simple up/down thc
[15:51:44] <ssi> what mesa hardware do you have
[15:51:47] <generic_nick|2> i want to build a plasma table
[15:51:54] <chopper79> 5i25 and a thcad-300
[15:52:10] <ssi> I'm redoing my table with a 5i25+G540
[15:52:11] <generic_nick|2> once i move into my new shop ill be building one
[15:52:17] <ssi> and the LCTHC
[15:52:17] <chopper79> 95% works fine, just need to work on few things
[15:52:51] <generic_nick|2> hopefully my cheap chineese plasma works for it
[15:53:12] <ssi> generic_nick|2: build the table, and then upgrade the machine if it gives you trouble
[15:53:19] <generic_nick|2> thats the plan
[15:53:28] <ssi> I went straight for the hypertherm pm45
[15:53:30] <generic_nick|2> i already have most of the mesa stuff needed
[15:53:38] <ssi> since everyone said they had good results with them
[15:53:50] <generic_nick|2> i have a Cut-50 with a thermodyne sl100 torch
[15:54:14] <generic_nick|2> it works suprisingly well for a $350 plasma
[15:54:20] <chopper79> Well I put in the net zpos-fb thcud.z-fb-out => axis.2.motor-pos-fb and the config launches and I get no following errors when I jog the z. I will have to see if this works on the machine now. I still wonder if it needs stepgen.2.position-fb somewhere in there
[15:54:33] <generic_nick|2> i built my entire jeep with it and then some
[15:54:34] <chopper79> I have a Hypertherm65 and a longevity
[15:54:43] <chopper79> i80
[15:54:44] <ssi> chopper79: do you get DRO readouts for Z in axis?
[15:54:51] <chopper79> yes
[15:54:56] <ssi> then I think you're fine
[15:54:59] <chopper79> sweet
[15:55:03] <ssi> try commenting out the net zpos-fb line and restarting
[15:55:07] <ssi> see if your DRO quits working
[15:55:13] <chopper79> ok brb
[15:55:18] <ssi> I think axis.2.motor-pos-fb drives the DRO
[15:55:20] <ssi> not sure though
[15:55:37] <generic_nick|2> do you use ball screws or lead screws?
[15:55:42] <ssi> on my plasma?
[15:55:44] <ssi> neither
[15:55:45] <generic_nick|2> yes
[15:55:47] <ssi> rack&pinion baby
[15:55:52] <generic_nick|2> oh nice
[15:55:58] <chopper79> it errors out
[15:56:11] <ssi> what's the error?
[15:56:23] <ssi> generic_nick|2: http://sphotos-d.ak.fbcdn.net/hphotos-ak-ash3/945659_10100133657177452_1008517863_n.jpg
[15:56:26] <generic_nick|2> you like the rack and pinion?
[15:56:32] <ssi> yea it works fine
[15:56:50] <chopper79> following error and not movement on DRO
[15:57:00] <ssi> chopper79: oh ok that's what I expected
[15:57:01] <chopper79> so it appears that the its oke
[15:57:05] <generic_nick|2> was it cheaper than screw options?
[15:57:07] <ssi> chopper79: yea I think you're in good shape
[15:57:15] <ssi> generic_nick|2: oh yeah, much cheaper
[15:57:17] <chopper79> That what it seems
[15:57:19] <generic_nick|2> cool
[15:57:24] <ssi> generic_nick|2: I have 54" of axis
[15:57:27] <ssi> would need three screws that long
[15:57:34] <generic_nick|2> dang
[15:57:35] <ssi> plus plasma needs to run high speed
[15:57:36] <generic_nick|2> yea
[15:57:46] <ReadError> my rack and pinion works awesome
[15:57:51] <ssi> so the screws would have to be high leade and thick diameter to resist whipping
[15:57:53] <ReadError> i have no measurable backlash at all
[15:57:54] <chopper79> Thank you for the help
[15:57:54] <ssi> would be expensive
[15:58:01] <generic_nick|2> good to know
[15:58:04] <ssi> ReadError: how do you tension the pinion?
[15:58:07] <ssi> did you see my picture?
[15:58:11] <ssi> that's my ghetto system :)
[15:58:11] <ReadError> springs
[15:58:11] <generic_nick|2> yes
[15:58:15] <chopper79> Now to go hook this up the my table and see what does or does not happen
[15:58:17] <generic_nick|2> looks good
[15:58:26] <ssi> chopper79: good luck
[15:58:32] <ReadError> ssi, i have the pro kit from cncrouterparts
[15:58:33] <chopper79> gonna need it
[15:58:39] <ssi> I built homemade 3:1 belt reductions
[15:58:41] <ReadError> you can probably get the spring assembly stuff
[15:58:46] <ssi> and a 1" pinion
[15:58:49] <ssi> so I have about a 1:1 drive
[15:58:55] <ssi> 3:pi actually
[15:58:59] <ssi> works out to a 0.9579 ratio

[15:59:16] <ssi> 0.9579"/rev
[15:59:32] <generic_nick|2> i can get away with something sloppy, it's just for jeep parts
[15:59:56] <ssi> that's only ~0.005" resolution, but it seems to be ok for what I'm doing
[16:00:17] <generic_nick|2> i do it by hand now, with a tape measure and a straight edge lol
[16:01:05] s1dev|away is now known as s1dev
[16:01:10] <ssi> honestly the hardest part is the table construction, axis mechanicals and such
[16:01:15] <ssi> once you get past that, it's pretty simple
[16:01:41] <generic_nick|2> yea ill just weld up something simple
[16:01:49] <ssi> how big a cut area do you need
[16:02:07] <generic_nick|2> i'd probably go 2x4' or something
[16:02:22] <ssi> if I had to do it over again I'd probably do 2x4
[16:02:25] <ssi> I never use the full 4x4
[16:02:36] <generic_nick|2> yea
[16:02:42] <generic_nick|2> maybe 2x6
[16:02:55] <generic_nick|2> i can see using the 6' for axle trusses and stuff
[16:03:09] <generic_nick|2> i dunno
[16:03:59] <generic_nick|2> well im off to do work. seeya

[17:07:11] <generic_nick|2> that is the actual one i got
[17:07:22] <PetefromTn> is that a harmonic drive unit?
[17:07:43] <skunkworks> PetefromTn, where are those videos!
[17:07:44] <generic_nick|2> i dunno
[17:07:57] <generic_nick|2> worm screw i believe, thats all i know
[17:08:11] <PetefromTn> Yeah that is about what most of them cost. Nicest part of this retrofit to linuxCNC is that I can build my own if I want and use any drivers or motors for it.
[17:09:01] <PetefromTn> skunkworks: Hey man I am gonna get this Z motor braking resistor installed and then I plan to make a short video showing the machine running, homing, controlling the flood coolant etc... Still long way to go before toolchange but it is getting there LOL
[17:09:40] <generic_nick|2> i gotta try and put an encoder on my spindle so i can rigid tap
[17:10:07] <generic_nick|2> and i also need to make the analog out on the 7i48 go 0-10+ even in reverse
[17:10:14] <generic_nick|2> if thats even possible
[17:10:36] <generic_nick|2> havent bothered to look yet since i havent needed reverse, ever.
[17:11:23] <PetefromTn> Me too I have been trying to get the CNC portion working so I can machine an nice adapter plate to hold my new spindle motor encoder...
[17:11:59] <generic_nick|2> mine's going to be a bit of a pain. it will need a belt drive to the encoder
[17:12:55] <generic_nick|2> i figured i'd wait till i got the mill moved into the new shop since ill need to pull the head apart anyways to get it out of my garage
[17:15:04] <PetefromTn> good plan. I considered making a belt driven spindle mounted encoder... not sure if that is the best thing or not LOL...at least for my machine.
[17:16:07] <generic_nick|2> works fine on my hardinge, thats how they do it from the factory
[17:17:26] <generic_nick|2> i just didnt feel like making brackets and whatnot lol
[17:18:02] <ssi> yeah it's fine... timing belts are synchronous :)
[17:20:37] <PetefromTn> honestly if I DID make a bracket and put timing belts to drive the encoder off my spindle directly it would save me a bunch of headaches LOL...

[17:22:02] <PetefromTn> just offset from each other?
[17:22:04] <ssi> are they spring-coupled?
[17:22:27] <skunkworks> On this machine - you grind a shim between the 2 small gears

[17:44:45] <IchGuckLive> JesusAlos: hi deskproto got a 2 plane cam
[17:45:30] hashfail is now known as gimps
[17:46:29] <JesusAlos> but is for machining
[17:46:37] <JesusAlos> no hot wire cutting
[17:46:41] <JesusAlos> no?
[17:47:19] <IchGuckLive> im using it that way BUT as you need the perfekt fit im using ProE with EDM module

[17:52:52] <Aero-Tec> HELLO
[17:53:02] <Aero-Tec> oops
[17:53:14] <Aero-Tec> was doing Gcode
[17:53:19] <Aero-Tec> need to do some threading
[17:53:25] <Aero-Tec> also some drilling
[17:53:46] <archivist> were pressing return to often too
[17:53:55] <Aero-Tec> was wondering what was the best way to go for hand coding the Gcode
[17:53:58] <IchGuckLive> JesusAlos: here is my full casel wire cut as you see 4 axis one cut http://www.youtube.com/watch?v=wT_ndXDZ0DU

[17:54:45] <Aero-Tec> the spindle has one index pulse per rev
[17:54:49] <JesusAlos> yes
[17:54:54] <JesusAlos> is like this
[17:54:54] <IchGuckLive> Aero-Tec: you can code in linuxcnc sim mode and reload as you need to see what is going on
[17:55:11] <JesusAlos> but with horizontal turn option
[17:55:24] <Aero-Tec> there is a link to some subs for doing lathe work
[17:55:28] <archivist> Aero-Tec, look at the g76 example that is in your examples
[17:55:38] <Aero-Tec> anyone know what the link is?
[17:55:57] <IchGuckLive> JesusAlos: the 4th(5) axis is along Axis X/U or Y/V
[17:56:01] <Aero-Tec> or where to find the subs?
[17:56:03] <archivist> locate g76 on your computer
[17:56:40] <Aero-Tec> I know, return to often, sorry
[17:57:12] <Aero-Tec> what is the best way to drill a deep hole?

[17:57:40] <archivist> gun drill
[17:57:44] <Aero-Tec> I wrote a sub for drilling in mach, my own peck drilling sub
[17:58:30] <Aero-Tec> not gun barrel deep, say 2.5 inches
[17:58:49] <Aero-Tec> I need it straight as possible
[17:59:09] <Aero-Tec> using twist drills
[17:59:22] <JesusAlos> Ich- You say do you use heeks to do this task?
[17:59:32] <IchGuckLive> yes
[17:59:44] <IchGuckLive> i made a XY UV post for standard things
[18:00:02] <syyl> 2,5" can be very shallow (40mm drill) or very very deep (1mm drill)
[18:00:09] <archivist> Aero-Tec, peck drilling is in the manual too
[18:00:11] <JesusAlos> and 5 axis
[18:00:13] <JesusAlos> ?
[18:00:48] <IchGuckLive> i turn the table by handcoding into heeks
[18:01:08] <IchGuckLive> G0 B45
[18:01:34] <Aero-Tec> does peck drilling run more true then just pushing through in one stroke or would would a whack of small pecks drill more straight?
[18:01:41] <IchGuckLive> or as i do alot of stuff by hand also
[18:02:11] <archivist> Aero-Tec, peck clears the chips therefore more true

[18:03:02] <archivist> peck often then, you choose
[18:03:49] <Aero-Tec> is there a drilling sub that does larger pecks st the start and then does smaller ones as it gos deeper?
[18:04:41] <JT-Shop> I'm pretty sure you would have to hand code that...
[18:04:54] -!- fomox has quit [Ping timeout: 264 seconds]
[18:05:47] <Aero-Tec> my sub would move in x and then out z then in again for x steps to break the chips, then do a clearing stroke to pull the chips out
[18:07:25] <Aero-Tec> mach did not have much for Gcode programming so was very limited, I wanted to add the change in pecking as it went deeper for faster drilling
[18:07:34] <JesusAlos> Ich- I must digest all the information
[18:08:37] <cradek> I've used a system that let you specify the first peck as a deeper one. in linuxcnc you'd have to do that with two lines of gcode
[18:14:47] <IchGuckLive> JesusAlos: let me quick upload a picture
[18:15:20] <IchGuckLive> JesusAlos: http://foengarage.de/xyuv_post.png

[18:16:18] <generic_nick|2> i wonder what the odds are of my kasooga knee mill's spindle fitting in my shizuoka. both are similar japanese machines.
[18:16:47] <generic_nick|2> i just pulled the spindle out of the kasooga. the shizuoka could use a newer one.

[20:11:34] <ssi> I don't have much, but aircraft spruce has all you need
[20:11:37] <gene78> probably wrong sign in a while loop.
[20:11:42] <ssi> and it's not that killin' expensive :)

[20:13:10] <PetefromTn> what rod do you use for the 4130 out of curiosity, you go stainless with the aircraft?
[20:13:11] <ssi> then experimental aviation is not the game you want to get into
[20:13:18] <ssi> 80SD2
[20:13:31] <PetefromTn> probably not for a number of reasons?
[20:14:06] <ssi> stainless works in a pinch, but 80SD2 is the ideal wire for 4130 in terms of normalization and crack-resistance
[20:14:17] <PetefromTn> wire or rod
[20:14:23] <ssi> rod
[20:14:41] <PetefromTn> no squirting aircraft frames I would hope LOL

[22:08:12] <ssi> trying to figure out how the 5i25-g540 pins map to the g540's pinout
[22:09:24] <ssi> it mostly looks right
[22:09:27] <ssi> but almost not quite
[22:09:28] <ssi> haha
[22:09:50] <ssi> [164859.716245] hm2/hm2_5i25.0: IO Pin 002 (P3-02): StepGen #0, pin Step (Output)

[22:10:17] <ssi> g540 pinout is pin 2 A-direction, pin 3 A-step
[22:10:56] <cradek> weird
[22:10:57] <ssi> oh wait
[22:11:07] <ssi> there's at least 4 different g540 manuals on the internet
[22:11:09] <cradek> I'd be surprised if the mesa firmware is that wrong
[22:11:09] <ssi> and they're not consistent
[22:11:12] <cradek> haha
[22:11:17] <ssi> G540 rev3 manual says 2 is step, 3 is dir
[22:11:19] <cradek> just plug it in and it'll probably work :-)
[22:11:21] <ssi> hahah
[22:11:31] <ssi> pin 16 charge pump
[22:11:34] <ssi> ok now we're getting somewhere
[22:11:51] <cradek> I think we have a working g540 sample config, don't we?
[22:12:31] <ssi> yeah, but I don't think they're 5i25-g540 samples are they?
[22:13:06] <ssi> I'm having to combine a bunch of different goofy elements in this build
[22:13:11] <ssi> 5i25-G540, gantrykins, THC
[22:13:20] <ssi> and I only sorta know what I'm doing :P
[22:13:22] <cradek> ah
[22:13:47] <PCW> gantrykins is the way of much pain
[22:13:49] <ssi> http://cdn.memegenerator.net/instances/250x250/33143446.jpg
[22:13:58] <ssi> PCW: is there a better way to go?
[22:14:12] <cradek> not using gantrykins is the better way
[22:14:23] <ssi> well I just need to slave two motors to Y
[22:14:29] <ssi> if it's doable without gantrykins, I'm all the happier
[22:14:31] <cradek> how do you need to home?
[22:14:45] <ssi> I sorta never got around to putting home/limits on Y
[22:14:48] <ssi> so that's up in the air :)
[22:14:49] <cradek> wiring two motors together is easy - homing is the issue
[22:14:55] <PCW> I think JA3 is better (if you need homing)
[22:14:58] <cradek> then wire them together and blissfully move on

[22:15:06] <ssi> JA3?
[22:15:30] <ssi> cradek: you mean wire them together in hal?
[22:15:41] <ssi> ie have one axis, but the stepgen inputs wired to both?
[22:15:42] <cradek> I mean wire one step and dir output to both amps
[22:16:02] <PCW> not easy with a G540
[22:16:04] -!- kmrhb has quit [Ping timeout: 256 seconds]
[22:16:04] <cradek> you can't really do that with hardware stepgen, except in firmware or hardware
[22:16:04] <ssi> physically doing that wiring would be more painful than I'd like
[22:16:21] <cradek> yet it's probably the least painful way :-)
[22:16:43] <ssi> if that's the case it'd be easier to give up either the mesa card or the g540
[22:16:45] <PCW> send the position command to both stepgens
[22:16:52] <ssi> PCW: ok yea that's what I was thinking
[22:16:53] <cradek> radio shack used to have these awesome arbitrary-db25-wirer-box things
[22:17:55] <cradek> if you had a time machine you could buy one
[22:18:37] <cradek> but yeah PCW's advice is better because it doesn't require you have a time machine
[22:18:53] <ssi> so how bad is it going to be if i want proper homing?
[22:19:11] <cradek> define proper
[22:19:33] <ssi> well in a reasonable universe, the two Y motors would be able to home to their own switches independently to self-square the gantry
[22:20:25] <PCW> Probably want JA3 for that (or better still motion patched so it knows how to home locked axis)
[22:20:26] <cradek> some people gate the step pulses with the switches - it's pretty horrible
[22:20:38] <ssi> PCW: so JA3 would allow me to define 3 axes with 4 joints? or what exactly
[22:21:15] <cradek> I/we/someone might work on slave-joint at fest in june
[22:21:17] <ssi> cradek: that'd be difficult with hardware stepping

[22:21:55] <cradek> ssi: yeah unfortunately it's quite a bit harder

[22:22:31] <cradek> for completeness this is the thing I was talking about: http://www.ebay.com/itm/251226001568
[22:22:34] <ssi> hurdle count is rising on this machine :(
[22:22:56] <ssi> cradek: fancy
[22:23:12] <ssi> so what's the problem with gantrykins?
[22:24:05] <cradek> world mode handling in everything but ja3 branch is flaky in various ways
[22:24:43] <ssi> I don't know what that means

[22:25:34] -!- Tecan has quit [Ping timeout: 272 seconds]
[22:25:58] <ssi> fair enough
[22:26:22] <PCW> Or just ignore de-skew homing for the time being
[22:26:23] <cradek> sorry if that sounds like a blowoff
[22:26:33] <ssi> I guess I'll start with trivkins and link the two stepgens to one axis
[22:26:38] <ssi> and then eventually move toward JA3
[22:26:42] <cradek> yes if you can ignore it and move on, definitely do that
[22:26:46] <ssi> it's fine
[22:26:51] <ssi> I ran it under mach with no limits at all
[22:27:00] <cradek> by the time you need homing, if you ever do, there might be a better answer like slaved joints
[22:27:07] <ssi> I just forced it square occasionally
[22:27:19] <ssi> nice thing about plasma is it runs in carpenter precision
[22:27:29] <cradek> yep for plasma that sounds absolutely adequate
[22:27:41] <ssi> I think that machine runs 0.005"/step right now
[22:27:51] <cradek> wow those are big steps
[22:28:11] <ssi> yea

[22:32:24] <cradek> ouch
[22:32:27] <ssi> right
[22:32:27] <PCW> not so good
[22:32:36] <cradek> that's not going to work out very well

[23:22:36] <generic_nick|2> that was only the empty head, knee, and table
[23:22:36] <ssi> what's the rate?

[23:22:57] <generic_nick|2> i got 180 for it
[23:23:08] <ssi> daw
[23:23:44] <generic_nick|2> i fit it all in my van lol
[23:24:02] <r00t4rd3d> down by the river?
[23:24:02] <generic_nick|2> gave the cherry picker a workout.
[23:24:20] <generic_nick|2> it's the rape-team van
[23:25:05] <generic_nick|2> it's mid conversion to be an a-team van replica but it's still white and windowless
[23:25:18] <generic_nick|2> so i figured that name suited it

[23:38:03] <generic_nick|2> cant wait to get the rest of the mill out of there. not sure if that will be very easy though.
[23:38:24] <generic_nick|2> the heaviest part is left
[23:39:02] <generic_nick|2> it certainly isnt fitting in the van
[23:40:03] <generic_nick|2> i think i need to rent a trailer
