[13:18:32] <skunkworks> ssi, you started with mach!
[13:18:38] <ssi> I did
[13:18:40] <ssi> shame on me
[13:18:42] <skunkworks> ;)
[13:19:00] <skunkworks> Converters are the best - they see what they where missing...
[13:19:05] <skunkworks> ;)
[13:19:17] <ssi> the CNC table was the first machine I did, and I bought tom caudle's cheap THC which had mach support out of the box
[13:19:21] <ssi> so it was simplest that way
[13:19:25] <ssi> but yea I'm looking forward to converting that machine
[13:19:29] <ssi> it's the only one I ever did on mach
[13:19:48] <ssi> that atrump mill I just finished is the fourth machine that I've gotten fully running on linuxcnc
[13:19:59] <ssi> all of them run mesa :D
[13:21:37] <skunkworks> Great!
[13:21:44] <skunkworks> mesa hardware is awesome
[13:22:16] <ssi> I'm debating how I want to handle the plasma table
[13:22:20] <ssi> it's a G540 driving those steppers right now
[13:22:26] <ssi> should I run it directly off parport
[13:22:30] <ssi> or stick a 5i25 in the mix
[13:22:36] <ssi> or ditch it and get different drives
[13:23:18] <jthornton> can you get enough speed with the G540?
[13:23:27] <jthornton> it's limited to what 50v?
[13:23:30] <ssi> yeah under mach I had at least 400ipm
[13:23:35] <ssi> right, and I have a 48v supply
[13:24:02] <Tom_itx> JT-Shop-2, what voltage do you run your steppers at?
[13:24:03] <skunkworks> how many pps is that?
[13:24:04] <ssi> also looks like those motors are wired half-coil
[13:24:08] <ssi> not sure why I did that exactly
[13:24:24] <skunkworks> *steps per second
[13:24:31] <ssi> skunkworks: dunno offhand... I still have the mach stuff setup, I should snapshot it before I blow it away
[13:24:37] <jthornton> Tom_itx, 70v
[13:24:55] <Tom_itx> the 203v is good to 80v right?
[13:25:00] <jthornton> ssi I can convert the mack xml file to stepconf
[13:25:04] <ssi> I've got a 3:1 belt reduction on the steppers and then a 1" pinion on the racks
[13:25:05] <jthornton> aye
[13:25:07] <ssi> jthornton: neat!
[13:25:18] <ssi> it worked out pretty close to 1:1 drive
[13:25:30] <ssi> 1 rev per inch that is
[13:25:38] <ssi> I think it's 3:pi
[13:26:37] <ssi> so that'd be ~6.36 rev/sec
[13:26:37] -!- kmrhb has quit [Ping timeout: 256 seconds]
[13:26:45] <ssi> and they're what, 180 steps per rev?
[13:26:50] <ssi> I forget now :P
[13:26:52] <skunkworks> 200
[13:27:03] <ssi> so 1273 full steps per second
[13:27:07] <skunkworks> but your g540 is microsteeping...
[13:27:10] <ssi> right
[13:27:18] <ssi> maybe 10k pps?
[13:27:36] <ssi> I've never done a software stepgen in linuxcnc
[13:27:38] <ssi> what's reasonable?
[13:28:12] <skunkworks> I would say if you want anything over about 30-40k steps per second - go with mesa.
[13:28:21] <ssi> gotcha
[13:28:26] <ssi> I may end up going mesa regardless
[13:28:34] <skunkworks> (hell I would go with mesa anyway.. it is only $89
[13:28:38] <ssi> yeah
[13:28:50] <ssi> I'm just wondering if I should try to get it overnighted to have it by the weekend :)
[13:28:56] <skunkworks> heh
[13:28:57] <skunkworks> sure!
[13:28:58] <ssi> their overnight shipping is pricey
[13:29:13] <ssi> I had the 7i77 kit for the atrump overnighted last week, it was almost $70 in shipping
[13:29:29] <skunkworks> that isn't mesa - that is ups/fedex...
[13:29:35] <ssi> well yeah I know
[13:29:41] <ssi> but mesa is about as far from me as possible
[13:29:43] <ssi> so the rates are high

[13:35:38] <ssi> I actually built that machine before the plasma table
[13:35:49] <ssi> the Y axis sucks, needs to be redesigned
[13:35:52] <ssi> the X and Z are pretty solid
[13:35:58] <syyl> is the table machined from solid?
[13:36:01] <ssi> yep
[13:36:01] <ssi> heh
[13:36:08] <ssi> it's all made of barstock
[13:36:09] <ssi> and all by hand
[13:36:17] <syyl> best way to do anything, machine from stock ;)
[13:36:19] <ssi> I designed it in solidworks and machined it all on my manual mill
[13:36:30] <syyl> :)
[13:36:34] <ssi> it was mostly a project I contrived to learn solidworks and machining
[13:36:44] <frallzor> cute
[13:36:56] <frallzor> I like it simple
[13:37:28] <ssi> the sides of the gantry are screwed to a piece of barstock that runs under the table on a pair of 1/2" thompson rails with ball linear bearings
[13:37:33] <ssi> and a screw in the center
[13:37:39] <ssi> but the whole thing rocks due to slop in the bearings
[13:37:49] <frallzor> china bearings?
[13:37:53] <ssi> I want to redesign it, fix the gantry in place, and move the table
[13:37:56] <ssi> no they're good bearings from mcmaster
[13:38:02] <ssi> it's just too much weight over too narrow a bearing base
[13:38:11] <ssi> and it's not centered well enough over the bearings
[13:38:30] <ssi> also the machine is so small that it's hard to find a reasonable spindle for it
[13:38:44] <ssi> I made a spindle once upon a time that's actually on another little machine this size that i never finished
[13:38:59] <frallzor> kress?
[13:39:14] <ssi> even a kress is a bit large for it
[13:39:20] <frallzor> dremel? =)

[13:40:34] <ssi> it's an ER chuck on a straight shaft that I bought on ebay
[13:40:38] <ssi> mounted in a body between bearings
[13:40:50] <ssi> and then a little 180W brushless RC motor mounted eccentrically in a cup
[13:40:55] <ssi> so you can rotate the cup to tension the belt
[13:41:40] <ssi> my house is like the isle of aborted projects :(

[16:38:41] <mazafaka> Thinking of all possible CNC-related side jobs at my free time makes me realize something: It is funny how people having USD1000-1250 saying with an optimistic manner about everything around, and people having USD650 just keep up they head with hands, and drink and drink and drink even though they feed a family. Russia itself has never yet seen such a stupid time with such prices and such rate of payment. Everybody are awaiting from the governm

[17:44:55] <ssi> I wish more 3d printing weenies would come over to real machining so they'd write some decent tools
[17:45:03] <ssi> the 3d printing toolchain is amazingly mature
[17:45:52] <ReadError> yea path planning and all
[17:46:04] <ssi> slicing is quite complex
[17:46:12] <ssi> and the slicers work way better than I expected
[17:46:23] <ssi> if they can write slicers, surely they can write 2d jet cam
[17:46:47] <ssi> the problem I always had with sheetcam was it seemed like it rendered all curves (including round holes) as line segments

[17:47:12] <ReadError> have you tried like, aspire ?

[17:47:25] <ReadError> maybe with a modified post processor for plasma ?
[17:47:47] <ssi> if I recall, it's expensive

[17:50:08] <Tom_itx> i did one for andy recently
[17:50:15] <frallzor> Aspire is good, if you intend on doing lots of signage, and 2D-stuff
[17:50:19] <ssi> when I first got my first lathe running and started asking people about cam
[17:50:27] <ssi> the general consensus was "nobody uses cam for a lathe"
[17:50:32] <ssi> just conversational
[17:50:33] <frallzor> I wouldnt pick it for doing anything but "artsy" stuff
[17:50:47] <Tom_itx> i never used it because most of our lathe work we just MDI'd the parts then saved the file
[17:51:08] <ssi> all of my lathe work has been hand-written code

[17:51:25] <ssi> I was pestering cradek to write one once upon a time
[17:51:28] <ssi> but I don't think it ever happened
[17:51:35] <ssi> and I'm not sure I'm smart enough to do it myself :P
[17:51:41] <Tom_itx> get me a file and i can see what i can do if you need something
[17:51:52] <ssi> nah don't need anything at the moment
[17:51:55] <ssi> my lathe is busted right now :(
[17:53:02] <ssi> so I also never had luck with holes on the plasma table
[17:53:06] <ssi> small holes suck
[17:53:16] <ssi> and cutting pilot holes sucks, because the edge is too hard to drill
[17:53:29] <ssi> so I thought about trying to incorporate a spot drill
[17:53:43] <ssi> even better would be an engraving bit that can mark plates and double as a spot drill
[17:54:20] <Tom_itx> mine is an old commercial package
[17:54:42] <frallzor> If I were to choose a kick-ass combination of "cad"-cam it would be rhino with rhinocam
[17:54:46] <ssi> part of my problem is, other than sheetcam, I've never used cam
[17:54:47] <frallzor> powerful stuff there
[17:55:01] <ssi> so starting with lathe (which is far more complex), I have too many mountains to climb
[17:55:06] <ssi> and I just deadlock every time
[17:55:12] <ssi> I figure if I ever get a mill going, I can learn mill cam
[17:55:19] <Tom_itx> frallzor, that stuff kimk linked looked pretty nice for multi axis work
[17:55:19] <ssi> then maybe I'll be in a position to figure out lathe cam
[17:55:37] <frallzor> Tom_itx which?
[17:55:37] <ssi> I never really liked rhino
[17:55:39] <Tom_itx> i forget what it was called now
[17:55:54] <Tom_itx> lemme find it
[17:56:07] <frallzor> Rhino is really powerful when you get the hang of it =)
[17:56:15] <ssi> did they ever get the osx version out?
[17:56:17] <frallzor> add some plugins that makes life easier, and youre set
[17:56:24] <ssi> that's about the only way I'd ever spend any signifdicant time with it
[17:56:29] <frallzor> its out in beta If I recall correctly
[17:56:34] <frallzor> free to use
[17:56:37] <ssi> it was out in beta a long time ago
[17:56:41] <ssi> but it wasn't remarkably usable
[17:56:48] <FinboySlick> frallzor: Is Rhino parametric now? Or is it still mostly surface based?
[17:56:48] <frallzor> maybe RC now
[17:57:03] <FinboySlick> I only used it a long time ago.
[17:57:08] <frallzor> surface based
[17:57:29] <ssi> I have too much solidworks built into my hands :/
[17:57:32] <frallzor> its really nice for that "non 100% technical modeling"
[17:57:46] <frallzor> Im also mainly a wiz at solidworks
[17:57:52] <FinboySlick> Bleh... That's nice for funky shapes but I'd stick to parametric if I had to make mechanical parts.
[17:58:01] <frallzor> but I prefer rhino due to its organical simplicity
[17:58:28] <ssi> FinboySlick: I agree
[17:59:04] <ssi> I've done some work with openscad, and it's pretty neat, but I'm not nearly as fast with it as I am solidworks
[17:59:34] <FinboySlick> My only (minor) annoyance with solidworks is that while they claim to have dynamic thessalation (for display), zoominb in on something that isn't curvy enough still gives you facets.

[18:39:06] -!- vladimirek has quit [Remote host closed the connection]
[18:39:37] <ssi> yet open source has GREAT additive manufacturing tools
[18:39:39] <ssi> ironic kinda
[18:39:51] <L84Supper> ssi: ?
[18:40:07] <frallzor> dont need good tools for additive stuffs
[18:40:11] <ssi> like I was saying earlier, the 3d printing toolchain is amazingly mature
[18:40:14] <L84Supper> just support for toy printers like the reprap
[18:40:17] <frallzor> just the software the machines supplies =)
[18:40:29] <frallzor> model in solid etc and export as stl etc
[18:40:37] <ssi> frallzor: yeah the broke-ass 3d printing community have no money, but tons of free time
[18:40:49] <L84Supper> the open 3d print tools are a joke
[18:40:49] <ssi> sitting around trying to figure out something to do now that they don't have any parks to occupy
[18:41:08] <L84Supper> they are only somewhat useful for GGG printers
[18:41:26] <frallzor> GGG?
[18:41:34] <L84Supper> glorified glue gun
[18:42:05] <L84Supper> there is nothing useful for SLS, DLP SLA, inkjet or combinations of them
[18:42:28] <frallzor> why have super sophisticated software with units that cant take advantage of it anyway? =)
[18:42:37] <ssi> the tools will emerge as the hackers get access to the tech
[18:42:46] <ssi> that's sorta my point
[18:42:54] <ssi> if the OSS guys had 5 axis mills
[18:42:57] <L84Supper> they are all stuck in GGG
[18:43:03] <ssi> even little hacky ones like the hoss machine
[18:43:07] <ssi> there'd be awesome free cam

[18:44:51] <frallzor> http://solidsmack.com/fabrication/botobjects-announce-worlds-first-full-color-3d-printer-for-the-desktop/ heard about this pile of BS? =)
[18:44:54] <FinboySlick> I still think people should do a modern rewrite of something like OpenCASCADE.
[18:45:05] <L84Supper> we have had to write everything, there was nothing that we could show customers for production applications
[18:45:08] frewsxcv is now known as frewsxcv94709
[18:45:11] <FinboySlick> (probably a monumental task, mind you)
[18:46:35] <L84Supper> GGG is a very small subset of additive manufacturing tech yet the hype is that it's going to revolutionize manufacturing
[18:47:02] <frallzor> well it allready has
[18:47:19] <generic_nick|2> anyone know of a good cheap company for machine shop insurance?
[18:47:29] <L84Supper> we must live in different worlds :)
[18:47:31] <FinboySlick> We need a very very fast pick-and-place robot that can work on the atomic scale ;)
[18:47:32] <frallzor> it made 3D-printing more available and upped the hype for 3D-printing
[18:47:37] <generic_nick|2> moving into a real shop and i need insurance on my machines
[18:47:53] <frallzor> so I´d say its somewhat of a revolution
[18:49:24] <L84Supper> GGG is for a small range of polymers that are deposited well by extrusion at slow speeds, it's 1000x slower than injection molding
[18:49:43] <ssi> it's certainly not replacing injection molding
[18:49:53] <ssi> it's 1,000,000,000x CHEAPER than injection molding for single qtys
[18:50:03] <frallzor> I cant see injection molding taking a place in every mans home =P
[18:50:13] <frallzor> although I could see 3D-printers
[18:50:15] <ssi> and orders of magnitude FASTER than injection molding for single qtys
[18:50:17] <L84Supper> SLA is 10-100X faster than GGG and at higher res
[18:50:19] <ssi> when you consider tooling times
[18:51:05] <frallzor> and alot more expensive =)
[18:51:21] <L84Supper> whats more expensive?
[18:51:26] <frallzor> SLA-printers
[18:51:31] <frallzor> and the material they use
[18:51:31] <ssi> pretty much everything is more expensive than FFF
[18:51:31] <L84Supper> not at all
[18:51:51] <L84Supper> SLA is simpler and has fewer moving parts
[18:52:14] <L84Supper> 1 moving axis vs 3
[18:54:09] <frallzor> replicator 2 vs form 1 about $1100 difference
[18:54:38] <frallzor> plus the "goo" for the form1 is way more expensive that some plastic tubing

[18:55:32] <frallzor> Im comparing things that exist as we speak =)
[18:55:41] <L84Supper> photopolymers are at parity and below GGG filament, they are easier to manufacture
[18:55:42] <ReadError> so whats a good off the shelf open source SLA printer
[18:55:52] <ReadError> that anyoone with some background can make?
[18:56:06] <ssi> I've seen a couple projects
[18:56:11] <ssi> but the form1 is the only one I've seen with any substance
[18:56:18] <frallzor> Ive seen one and that was the form 1
[18:56:25] <L84Supper> form1 uses a laser and galvos
[18:56:25] <frallzor> that was supposed to be open source
[18:56:45] <L84Supper> there is an open laser + galvo setup

[19:07:27] <L84Supper> the cost of the raw materials for GGG filament or SLA photopolymers are about the same, photopolymers just need to be mixed, filaments need the extra step of being extruded, photopolymers will drop well below the price of filaments

[19:09:05] <ReadError> i want to do it
[19:09:18] <ssi> ReadError: my only concern would be the speed

[19:09:29] <ssi> i've seen some screw based delta frames, and they're SLOOOOW
[19:09:42] <ReadError> so its like a super ghetto 5 axis
[19:09:45] <ssi> and you won't get extra DOF without extra motors
[19:09:52] <ssi> you'll need six vertical axes I think

[19:51:19] <jdh> perhaps it's just me, but I'd go with the one that says 1) Bipolar (parallel) connection

[19:53:26] <Connor> Don't most do those in series ?
[19:53:40] <Connor> what sort of driver you using? Can it handle 6 amps ?
[19:56:27] <jdh> that's a hefty stepper
[19:56:47] <Connor> Nema 34
[19:58:06] <Connor> 1200 Oz-in
[19:58:48] <Connor> Wow. GammaX-Shop What are you using that on? Z axis ?
[19:58:55] <GammaX-Shop> yup
[19:59:07] <Connor> Which machine? and why parallel vs series ?
[19:59:15] <GammaX-Shop> yeah I got 7.2amp drivers
[19:59:31] <GammaX-Shop> Connor, the torque/speed chat looks rteal good
[19:59:46] <Connor> What machine ?
[19:59:59] <GammaX-Shop> pm45
[20:00:01] <ssi> it depends on the driver
[20:00:12] <ssi> series makes the inductance go up by a square factor
[20:00:37] <ssi> and the voltage you want to run is related to the inductance of the motor

[20:01:50] <GammaX-Shop> so back to my question.... what color wires get attached together lol
[20:01:56] <GammaX-Shop> cant figure out that little wire diagram
[20:02:21] <ssi> red/green together, blue/yellow together, brn/org together, blk/wht together
[20:02:23] <Connor> wire BLU and Yellow toggether for A+,
[20:02:57] <Connor> Red Green for A-, Brown Orange for B+ and Black white for B -
[20:03:03] <Connor> Doh, SSI beat me too it.
[20:03:09] <ssi> SORRY
[20:03:14] <GammaX-Shop> and thats for parallel?
[20:03:17] <ssi> yep
[20:03:20] <Connor> yea.
[20:03:27] <GammaX-Shop> that crap diagram does not lead me to belieave that lol
[20:03:40] <Connor> Nothing wrong with the diagram..
[20:03:57] <ssi> I have to agree with connor on this one
[20:04:06] <Connor> I guess they could have used connector dots...
[20:04:15] <jdh> one of those lines does look a little funky
[20:04:55] <Connor> the ones in the middle section are not connected.. they're cross-overs..
[20:05:00] <GammaX-Shop> that diagram leads me to beleive blue and green is A+, I beleive you all though lol
[20:05:28] <ssi> I don't see how you came to that conclusion
[20:06:49] <GammaX-Shop> I do! lol
[20:06:57] <GammaX-Shop> ok lemme get back to wiriin up my z!
[20:07:00] <jdh> perhaps he is color blind.

[20:10:09] <GammaX-Shop> also, if you needed to make felt wipers for a lathe.. which felt would you buy? THanks!
[20:12:47] <GammaX-Shop> im deff buildin a plasma cnc router next! prolly take me a few months though..
[20:12:49] <jdh> mcmaster sells felt by density
[20:13:18] <jdh> shippping is probably way more than cost though\

[20:17:49] <jdh> then I win.
[20:17:54] -!- Wildhoney has quit [Ping timeout: 272 seconds]
[20:17:57] <ssi> in the time it takes to get grainger to get things to their store, I can have mcmaster ship it to me
[20:18:01] <ssi> everything's overnight
[20:18:06] <ssi> and on a couple rare occasions, I've gotten stuff same day
[20:18:12] <ssi> (it's expensive if you ask for same day though)
[20:18:26] <jdh> and, you have to live in atlanta... nothing could make up for that!
[20:18:39] <ssi> I don't live in atlanta, but I work in atlanta :)

[20:20:51] <jdh> another few weeks
[20:21:11] <GammaX-Shop> mcmaster is a grainger?
[20:21:17] <ssi> hahaha no
[20:21:25] <ssi> grainger wishes it was mcmaster
[20:21:28] <jdh> grainger probabaly gets things from mcmaster
[20:21:40] <GammaX-Shop> Is there only 1 mcmaster place/
[20:21:48] <ssi> no, there's a half dozen or more
[20:22:15] <ssi> or less: Robbinsville, New Jersey; Santa Fe Springs, California; Atlanta, Georgia and Cleveland, Ohio.
[20:22:18] <ssi> :D
[20:22:27] <jdh> I've only gotten things shipped from atl
[20:22:27] <ssi> oh and chicago
[20:22:29] <ssi> that's the main one I think
[20:22:32] <ssi> jdh: where are you?
[20:22:37] <jdh> .nc.us
[20:22:55] <ssi> yea you'll get atl unless something's out of stock
[20:23:01] <ssi> how long is shipping from them for you?

[20:23:07] <jdh> next day usually
[20:23:11] <ssi> yea
[20:23:14] <jdh> sometimes 2
[20:23:17] <ssi> I wonder if it's that way everywhere
[20:23:17] <GammaX-Shop> i wish there was one in denver
[20:23:22] <ssi> I get everything next day if it's in stock in atl
[20:23:25] <GammaX-Shop> I got grainger right down road so that aint bad.
[20:23:28] <jdh> never same day?
[20:23:28] <ssi> but I love mcmaster
[20:23:33] <ssi> occasionally
[20:23:34] <GammaX-Shop> and a Harbor freight ;)
[20:23:35] <ssi> if it's odd stock
[20:23:39] <ssi> too big for ups
[20:23:41] <ssi> they'll courier it
[20:23:55] <jdh> I have a friend that lives in atl. if he orders in the morning, its sometimes there in the afternoon
[20:24:05] <jdh> via UPS
[20:24:07] <ssi> it's happened, but it's not predictable

[21:54:14] <L84Supper> http://linuxcnc.org/docs/html/hal/components.html
[21:54:16] <WalterN> L84Supper: I dont know what they are called... they are a novelty thing, like a fancy paper weight
[21:54:29] <JT-Shop> oh I misread your question
[21:54:40] <ssi> I guess I'll try using comp to create a component and compile it to C and use that for a starting point
[21:54:40] <andypugh> ssi: You can compile into C and see what it comes up with as a starting point, but otherwise you will need to look at existing modules and see how they work. However, many of the distributed hal components are written in .comp
[21:54:45] <L84Supper> WalterN: have a pic?
[21:54:55] <JT-Shop> writing a c component or a comp generated component?
[21:54:56] <WalterN> uh
[21:54:59] <WalterN> I can look
[21:55:26] <ssi> JT-Shop: I'm basically just trying to get to where I can give gpios on this board hal pins and flip them from within hal
[21:55:30] <ssi> I imagine that's going to require writing a driver
[21:55:38] <ssi> or trying to figure out how to adapt mike's beagle_gpio driver

[21:56:08] <JT-Shop> aye
[21:56:09] <L84Supper> by sometime this summer there should be a front end for Linuxcnc with features found in Repetier such as slicing, homing, etc etc
[21:56:36] <L84Supper> WalterN: that should make Linuxcnc easier to use for 3dp
[21:56:36] <ssi> oh so here's an easier question
[21:56:45] <ssi> I want to run some stuff by you guys about Estop and machine enable
[21:56:59] <ssi> the mill I just did, the one outstanding thing I need to sort out is a hardware estop
[21:57:23] <ssi> there's a contactor in the power box, and the power for the contactor loops through the interface box
[21:57:31] <ssi> so basically when the box is plugged in, that completes the circuit
[21:57:42] <ssi> and then ther's a green button on the front of the machine that powers the contactor, which then self-latches
[21:57:54] <ssi> I Want to replace the loop inside the interface box with an SSR
[21:58:17] <ssi> and then have an estop button that's double pole, that both interrupts the contactor line and breaks an io line to the mesa card
[21:58:30] <ssi> is it possible to set hal up so that io line also controls the status of the F1 estop in axis?
[21:58:40] <JT-Shop> yep
[21:58:44] <andypugh> ssi user-enable -in
[21:58:59] <ssi> second, i want to have a momentary button on the machine that toggles the state of machine enable, F2
[21:59:08] <ssi> is it possible to amke a momentary button toggle a pin?
[21:59:15] <andypugh> Yes
[21:59:16] <ssi> ok
[21:59:18] <JT-Shop> yep
[21:59:29] <andypugh> toggle2nist
[21:59:37] <JT-Shop> external e stop http://www.linuxcnc.org/index.php/english/forum/47-hal-examples/25861-external-e-stop
[21:59:58] <ssi> ok cool

[22:09:22] <WalterN> L84Supper: like this... http://www.shortcourses.com/images/b7ch3/portrait.jpg
[22:09:46] <ssi> it drills each pipe, looping in Y
[22:09:54] <ssi> then jumps to the next hole in X

[22:10:55] <mhaberler> ssi: I've talked to Charles about the gpio driver for bb; are you willing to put in some effort into it? we would help with a bit of directions if so; note that can be done on 3.8 right now without xenomai
[22:11:22] <ssi> mhaberler: I would love to put effort into it... i'm just having a bit of learning curve trouble right now, but I'm dogged :)
[22:11:55] <mhaberler> good - codename for the xenomai effort was 'Operation Leatherbutt' ;)
[22:12:00] <ssi> hahaha
[22:12:13] <mhaberler> wanna see the leather ;-?
[22:12:24] <ssi> I have a close friend who has some am335x experience
[22:12:29] <ssi> he designed the adtrap on kickstarter
[22:12:32] <ssi> and he's working closely with TI
[22:12:42] <ssi> he's gonna help me with linuxcnc on the bbb
[22:12:43] <L84Supper> lederdupa?
[22:12:47] <mhaberler> anyway it boils down to the setup sequence really, so as not to conflict with the PRU driver
[22:13:19] <ssi> so as I understand it, you could potentially have the PRU running code attached to some of the GPIO pins,
[22:13:21] <mhaberler> Charles isnt on irc; can we do this on the devlist, and which real name would you appear under there?
[22:13:31] <ssi> and have the soft GPIO driver on other pins
[22:13:35] <ssi> Ian McMahon
[22:13:38] <ssi> and I guess I need to get on the list
[22:14:08] <mhaberler> we have decided there should be a separate hal driver for the non-time-critical / non PRU managed pins, which requires a bit of coordination
[22:14:39] <mhaberler> yes, that would help; just ping us there and we go from there
[22:14:44] <ssi> so you're thinking forget about xenomai/rtapi, just have PRU for RT tasks and hal_gpio for user mode?
[22:15:00] <mhaberler> ha?
[22:15:13] <mhaberler> let me state what the issue is:
[22:15:32] <mhaberler> we have the PRU stepgen driver, which wiggles the pins it needs for stepgen just fine
[22:15:39] <mhaberler> it does _not_ wiggle any others
[22:15:48] <ssi> right
[22:16:30] <mhaberler> we think we should use a separate hal driver for those gpio pins which are not managed/used by the PRU; that'd be an extra unnecessary dependency
[22:17:11] <mhaberler> that would in principle look like hal_gpio.c except for the setup sequence in rtapi_app_init
[22:17:39] <mhaberler> we need to decide whether sysfs digging is the right way to go; I assume the answer is yes
[22:18:15] <mhaberler> I also think there's no point anymore in targeting the 3.2 non-dtb kernel, the 3.8 xeno kernel is pretty close
[22:18:29] <WalterN> L84Supper: so yeah, I've always wondered what kind of machine makes that

[22:18:55] <WalterN> not that I've ever actually looked
[22:18:56] <mhaberler> so its either sysfs or dtb, but I must say I dont fully understand if there's an either-or here, I am a dtb illiterate
[22:19:19] <mhaberler> that's the exploratory part really which we should discuss
[22:19:35] <ssi> I don't know much about sysfs or dtb either, but I'm going to try to come up to speed
[22:19:39] <L84Supper> WalterN: laser crystal engraving or subsurface photo crystal engraving
[22:19:51] <ssi> I'm writing a list introduction now, and then I have to run
[22:20:03] <L84Supper> WalterN: the laser get focus inside the glass, not at the surface
[22:20:04] <mhaberler> nb: you can build a 'sim' build (aka --with-threads=posix plus --enable-drivers) and have full I/O functionality, only bad timing
[22:20:17] <mhaberler> but thats irrelevant for driver writing
[22:20:22] <mhaberler> great, see you there
[22:20:27] <ssi> hm I may have missed --enable-drivers
[22:20:31] <ssi> I have it built and sorta running
[22:20:36] <ssi> although I've never gotten it into axis
[22:20:40] <L84Supper> WalterN: http://www.ucrystal.com/
[22:20:42] <ssi> just been able to poke at halcmd a bit
[22:21:14] <mhaberler> ok, on weekend I'll get me and Charles a 3.8 kernel so we can compare notes
[22:21:28] <ssi> ok cool
[22:21:31] <ssi> I have a second BBB coming as well
[22:21:33] <ssi> dunno why
[22:21:36] <ssi> I guess I just like spending money

[22:21:44] <ssi> alright, talk to you later
[22:21:47] <ssi> thanks for the help!
[22:21:53] <ssi> also, thanks JT and andy for the hal tips :D
[22:23:52] <WalterN> L84Supper: so could I do that with my 808nm 30 watt laser? :3
[22:24:51] <L84Supper> WalterN: if you can control the focus precisely enough
[22:26:09] <JT-Shop> no problem
[22:26:43] <Tom_itx> JT-Shop, do you know of a pendant spindle control code i could look at? i'm not so happy with the behavior on mine
[22:26:45] <JT-Shop> 2 down 6 to go
[22:27:07] <JT-Shop> what kind of pendant?
[22:27:28] <Tom_itx> handheld with a button for spindle on off MPG etc
[22:27:51] <Tom_itx> wired into the mesa card
[22:28:02] <JT-Shop> I guess you would have to knit one together from the examples
[22:28:09] <JT-Shop> is each input seperate?
[22:28:12] <Tom_itx> i need to look mine over again
[22:28:26] <Tom_itx> i can post the latest files
[22:28:42] <Tom_itx> everything else seems to work pretty good except the spindle control
[22:28:43] <JT-Shop> I assume each function is a small bit of HAL
[22:28:54] <JT-Shop> single button for on and off?
[22:28:55] <Tom_itx> yep
[22:29:10] <JT-Shop> using halui?
[22:29:15] <Tom_itx> it's using toggle2nist etc
[22:29:21] <Tom_itx> yes i believe
[22:29:32] <JT-Shop> does it get confused?
[22:29:41] <Tom_itx> it messes up axis
[22:29:53] <JT-Shop> yikes!
[22:30:01] <JT-Shop> how does it mess up Axis?
[22:30:07] <Tom_itx> stalls out
[22:30:14] <Tom_itx> takes like 2 min to recover
[22:30:20] <Tom_itx> sometimes
[22:30:24] <JT-Shop> that is an error then
[22:30:30] -!- stsy has quit [Client Quit]
[22:30:38] <Tom_itx> i need to figure out the exact code problem and resolve it
[22:31:31] <Tom_itx> i'll post the hal file
[22:31:33] <JT-Shop> halui.spindle.xxxx seems straight fwd at a glance
[22:31:39] <JT-Shop> ok
[22:31:59] <Tom_itx> at the time it seemed i had something else i wanted it to look for but i can't recall what it was now
[22:32:19] <Tom_itx> i think i used the basic spindle examples posted
[22:32:47] <JT-Shop> on the forum or in the manual?
[22:33:08] <Tom_itx> i don't recall

[22:36:24] <Tom_itx> those are right off the machine
[22:36:30] <Tom_itx> my_jog is the one
[22:36:48] <Tom_itx> haven't cleaned em up yet either
[22:37:11] <JT-Shop> LOL I noticed
[22:37:21] <Tom_itx> been working on em :)
[22:37:43] <Tom_itx> spindle is at the bottom
[22:38:37] -!- atom1 [atom1!~tom@unaffiliated/toml/x-013812] has joined #linuxcnc
[22:38:43] <JT-Shop> you have a toggle and toggle2nist mixed together in the spindle section
[22:40:04] <Tom_itx> i don't remember why i did that now but i think i had a reason
[22:40:09] <JT-Shop> and maybe that is correct....
[22:40:27] <Tom_itx> i wanted to not allow it if it was in auto mode
[22:40:32] <Tom_itx> and running
[22:40:40] <Tom_itx> but if it was paused then allow it
[22:40:48] <Tom_itx> something like that
[22:40:50] <JT-Shop> ok
[22:40:54] <JT-Shop> makes sense
[22:40:58] <Tom_itx> i need to sit down and re think the logic
[22:41:04] <Tom_itx> it's been a while.
[22:41:11] <Tom_itx> i do know it's not working as expected
[22:41:36] <Tom_itx> some of it could be the reverse logic required because i'm using the 7i43 gpio direct
[22:41:59] <Tom_itx> and had to add pullup / pull down to them

[23:30:07] <Tom_itx> yup
[23:30:22] <Tom_itx> i should flow chart the whole pendant
[23:30:50] <Tom_itx> i'm sure there's stuff in the file i don't need
[23:31:40] <JT-Shop> wasn't there something that did that?
