[00:00:11] <coors> but i am pretty new and don't know too well what to look for
[00:00:20] <jdh> linearmotionbearings2008 for cheap chinese ones
[00:00:26] <coors> i am thinking about dumpster cnc ones atm
[00:01:09] <coors> are those any good?
[00:01:31] <coors> i am primarily looking for people who have used them and can tell me a bit more what you can expect from them
[00:01:32] <JT-Shop> you looking to build something from scratch?
[00:01:35] <jdh> actually, I don't know if he has acme screws. His ballscrews are cheap and arguably better than acme
[00:01:50] <coors> yeah, from scratch
[00:01:50] <JT-Shop> acme is manual, ball screws are CNC
[00:02:06] <jdh> I have acme on my cnc router
[00:02:13] <coors> well, the dumpstercnc ones are acme and supposed to be popular
[00:02:17] <jdh> which kind of leads to cnc-suckage
[00:02:25] <JT-Shop> LOL
[00:02:28] <coors> :)
[00:02:33] <jdh> but, they are dirt cheap.
[00:02:37] <coors> well, ballscrews can have bad backlash, too
[00:02:54] <coors> have you measured backlash on your machine by any chance?
[00:02:57] -!- servos4ever has quit [Quit: ChatZilla 0.9.85 [SeaMonkey 2.0.11/20101206162726]]
[00:03:04] <JT-Shop> I've seen some acme with delrin preloaded nuts that have little backlash
[00:03:11] <jdh> .001" to .0025"
[00:03:14] <andypugh> Aye, I have some oversize bals on order to try to improve my Y axis.
[00:03:24] <JT-Shop> sure but ballscrews don't have the friction of the acme
[00:03:29] <jdh> acme has a lot more waste
[00:03:32] <coors> http://www.cncrouterparts.com/dumpstercnc-acme-assembly-p-36.html
[00:03:39] <andypugh> But I suspect that something has actually come loose.
[00:04:04] <JT-Shop> yuck!
[00:04:05] <coors> i am trying to get <0.001"
[00:04:18] <coors> or is that just unrealistic?
[00:04:19] -!- blommer has quit [Ping timeout: 246 seconds]
[00:04:21] <JT-Shop> yep
[00:04:22] <jdh> getting that last 0.005" would be expensive
[00:04:26] <coors> what i really wanna do is pcbs
[00:04:30] <jdh> err... last 0.0005"
[00:04:39] <L84Supper> http://buildyourcnc.com/CNCMachineMechanicalParts.aspx for slow screws these work
[00:04:49] <coors> i got around 0.004 with hardware store parts
[00:05:10] <jdh> you can make anything if you want to pay for it.
[00:05:13] <coors> but i wanted something a little better for the linear motion stuff and a new gantry probably
[00:05:38] <coors> speed should be >10ipm, so not terribly high
[00:05:44] <r00t4rd3d> I used my machine to make a wooden mallet today :D
[00:05:47] <L84Supper> the spring actually forces the plastic radially and axially into the screw as it wears
[00:06:18] <jdh> I'd prefer a pair of ball-nuts
[00:06:22] <jdh> but, for the price...
[00:06:28] <coors> yeah, that's what i am using right now
[00:06:35] <coors> two nuts spaced with a screw
[00:06:53] <coors> i'm just using plastic wing nuts
[00:07:16] <coors> basically i am looking for better ones that aren't crazy expensive
[00:07:27] <L84Supper> http://www.haydonkerk.com/LinearActuatorProducts/LeadScrewsAndNuts/Nuts/CMPSeriesNuts/tabid/255/Default.aspx or these
[00:08:09] -!- blommer [blommer!~blommer@] has joined #linuxcnc
[00:08:38] <coors> how come those never spec backlash though?
[00:09:09] <coors> are those ones that you are using?
[00:09:45] <andypugh> Cheap ballnuts are quite cheap: http://www.zappautomation.co.uk/en/63-chinese-brand-ballnuts
[00:09:50] <L84Supper> it's 0 until you've melted or worn out the compensation
[00:10:02] <jdh> http://www.ebay.com/itm/250476169366
[00:10:28] -!- skunkworks has quit [Ping timeout: 252 seconds]
[00:11:09] <L84Supper> in China I can get them next day, it takes me a week to get them to Chicago
[00:11:09] <coors> so 0 means actually not measurable
[00:11:16] <coors> and not something like 0.001" or so?
[00:11:46] <L84Supper> the nut has an interference fit to the screw
[00:12:38] <L84Supper> you'll probably measure the flex of the polymer vs lash when they are new
[00:13:02] <L84Supper> but again they are not for long life or high speeds
[00:13:50] <coors> so that's true for any anti backlash ballscrew i can find?
[00:14:07] <coors> so there is no real reason to buy more expensive ones except for load capacity and life?
[00:14:58] <L84Supper> ballscrews will have less drag
[00:15:25] <jdh> way less
[00:15:55] <jdh> and are prettier
[00:16:20] <jdh> and really, if you have never chased ball nut balls around a hardwood floor, it's just something you need to do once (or twice)
[00:16:28] <L84Supper> lol
[00:16:37] <coors> :)
[00:16:50] -!- micges has quit [Quit: Leaving]
[00:17:02] <L84Supper> so thats what the screw cover is for
[00:17:47] <coors> hmm, i guess i'll go for the chinese ones then
[00:17:55] <coors> didnt realize all those are 0 backlash actually
[00:18:04] <coors> always thought some of them were just crap
[00:18:14] <jdh> they are "0"
[00:18:35] <L84Supper> I'm building a z-axis with them this evening
[00:18:59] <coors> oh, i'd appreciate it if you let me know how that goes
[00:19:00] <L84Supper> slow speed printer, 6mm/minute
[00:19:05] <coors> and if they are any good
[00:19:27] <L84Supper> they work fine, not the first time I've used them
[00:19:39] <coors> 6mm/min is really slow :)
[00:20:09] <L84Supper> 1/2" acme 10 TPI surplus screws ~$10 ea 36"
[00:20:36] <coors> which ones are you using there?

[00:22:31] <coors> oh and the cmp nut to go with it?
[00:23:21] <coors> where do you get your couplers from though?
[00:23:39] <L84Supper> http://stores.ebay.com/Precision-Tech-Machining-LLC?_trksid=p2047675.l2563
[00:24:19] <L84Supper> must be sold out right now
[00:24:36] <jdh> lovejoy couplers aren't so great for backlash
[00:24:42] <coors> well, but the store itself looks interesting
[00:24:53] <coors> got a lot of stuff i need to go through now :)
[00:25:08] -!- skunkworks [skunkworks!~chatzilla@str-broadband-ccmts-ws-26.dsl.airstreamcomm.net] has joined #linuxcnc
[00:25:37] <L84Supper> nope, dodn't use the lovejoy
[00:25:52] <L84Supper> trying to find the coupler link
[00:26:18] <jdh> oldham style couplers from mcmaster maybe
[00:26:46] <coors> actually, that ebay store has 1/4" couplings
[00:27:08] <jdh> lovejoys
[00:27:09] <coors> i was just using freezer plastic line as coupler for that size
[00:27:24] -!- andypugh has quit [Quit: andypugh]
[00:27:59] <coors> so i think i might get away with that
[00:28:08] -!- Nick001 [Nick001!~Nick001@] has joined #linuxcnc
[00:28:25] <coors> can you guys cut aluminum on your machines and make a small adapter plate for me?
[00:28:31] <coors> i'll compensate you of course
[00:29:08] <L84Supper> dumpster cnc has the couplers
[00:29:36] <L84Supper> http://www.dumpstercnc.com/acme_12101.html
[00:30:10] <L84Supper> http://www.dumpstercnc.com/couplers.html
[00:30:28] <jdh> not so friendly for any misalignment
[00:31:19] <coors> yeah those are the ones i was looking at earlier though
[00:31:36] <r00t4rd3d> i snapped a motor shaft using their coupler
[00:31:44] <r00t4rd3d> i was misaligned though

[00:32:22] <L84Supper> I was stuck in the US during Chinese new year and i found these
[00:32:59] <L84Supper> he ships real fast
[00:33:11] <r00t4rd3d> i have 3 couplers/lead nuts from them
[00:33:16] -!- pjm_ [pjm_!~pjm@uhfsatcom.plus.com] has joined #linuxcnc
[00:33:30] <coors> are you happy with them?
[00:33:35] <r00t4rd3d> yeah
[00:33:47] <r00t4rd3d> just make sure your screws are straight
[00:34:13] <L84Supper> I've used his Anti-backlash Leadnuts on that 1/2 -10 tpi acme
[00:34:34] <coors> and you guys use just a motor coupler and a single bearing block on the opposite end?
[00:34:37] <L84Supper> speeds up to 1cm/sec but a 50% duty cycle
[00:34:40] <r00t4rd3d> i use the 3/8-16 stuff with hardware store threaded rod
[00:34:53] -!- pjm has quit [Ping timeout: 256 seconds]
[00:35:08] <L84Supper> I have with a real nice linear bearing
[00:35:43] <L84Supper> over a million cycles since Jan with no problems so far
[00:36:49] <coors> hmm, i think i might go with the acme
[00:37:16] <coors> so the drivetrain question seemes to be answered
[00:37:37] <coors> are you using supported rods as guides with that or tube?
[00:37:45] <L84Supper> http://www.automationtechnologiesinc.com/products-page/nema-23/nema-23-bipolar-stepper-motor-156-oz-in-%C2%BC%E2%80%9D-dual-shaft-with-a-flat using this motor
[00:37:51] <coors> i was told that tubes are more rigid than rods, is that correct so far?
[00:38:29] <coors> i got motors and homebuilt stepper drivers, that part is easy
[00:38:38] <coors> i'm just struggling on the mechanical side of things
[00:38:52] <Valen> tube would be more rigid per weight I believe
[00:39:10] <coors> it appears that way, yet i didnt see much of it
[00:39:21] <coors> the best i saw so far was supported rods i suppose
[00:40:03] <Valen> http://wiki.answers.com/Q/Which_is_stronger_solid_steel_rod_or_hollow_steel_pipe

[00:40:49] <coors> on this one, are the delrin nuts anti backlash?
[00:41:37] <coors> Valen: I like that explaination
[00:41:39] <L84Supper> http://www.automationtechnologiesinc.com/products-page/ballscrews-nuts/1605-series-365mm-flanged-nut-and-screw had these been in stock I would have chosen this over the lead scews
[00:41:52] <coors> basically they say it depends, that's what i take from it :)
[00:42:11] <Valen> they don't they say for the same OD a solid is stronger
[00:42:20] <Valen> for the same weight a pipe is stronger
[00:42:53] <Valen> if you are doing a new build look at linearmotionbearings2008 on ebay
[00:42:57] <coors> yeah but which one is the one that matters more for a cnc?
[00:42:59] <L84Supper> so based on diameter the solid is more rigid than a tube
[00:43:01] <Valen> he does ballscrews super cheap
[00:43:27] <Valen> it depends on your design, if you are space limited use solid bar, if you have lots of space, use a pipe
[00:43:27] <L84Supper> the bearings are not very good
[00:43:44] <Valen> ours is built of hollows, that we are going to fill with pressurised foam ;->
[00:43:59] <L84Supper> the bearing supports have *detents* :)
[00:44:20] <L84Supper> until you wear them in
[00:44:23] <Valen> nice
[00:44:29] <Valen> anyway off to play with electronics
[00:44:53] <coors> have fun
[00:44:55] <coors> thanks!
[00:45:00] <L84Supper> coors: it depends on how much use you machine is going to see
[00:45:17] <coors> well, the one i am ripping apart was used every other day
[00:45:24] <coors> mostly hdpe and pcb stuff
[00:45:28] <L84Supper> we use air bearings for printers since they never stop moving
[00:45:37] <coors> problem was it wasn't as precise as i wanted it to be
[00:45:48] <L84Supper> a ballscew would be worn out in a few weeks
[00:46:01] <Valen> L84Supper: nice, I'm looking at air for the new mill
[00:46:09] <Valen> air and linear motors for added win
[00:46:25] <L84Supper> yeah, can't beat them for durability
[00:46:28] <Valen> adding precision is *hard* and acme threads are not the way to attain it
[00:47:02] <coors> valen: how precise is your machine?
[00:47:09] <coors> have you tried making PCBs?
[00:47:23] <coors> i guess my alternative is to buy a training emco and just go with that
[00:47:36] <Valen> http://www.vapourforge.com/jake/temp/milled-pcb-for-spinzster.jpg
[00:47:37] <coors> but i still got hope i can hack something together that'll work for me
[00:47:48] <Valen> we use glass scales and measuure to .001mm
[00:48:30] <coors> what's the ic in the middle? tqfp-44 avr or something?
[00:48:32] <Valen> if PCB milling is your goal you need a good spindle, and decent screws
[00:48:38] <Valen> coors: 16u4
[00:48:49] <coors> ok, that's the kind of stuff i am looking for
[00:49:01] <Valen> I'd go all china, ballscrews and a spindle
[00:49:07] <Valen> you *need* RPM
[00:49:14] <coors> the spindle i got from wolfgangengineering
[00:49:21] <L84Supper> or modify and inkjet to print mask and then laser cut
[00:49:27] <L84Supper> and/an
[00:49:28] <coors> http://www.wolfgangengineering.com/Spindles.php
[00:49:42] <Valen> though honestly we only use it because we are impatient
[00:49:52] <Valen> getting PCB's from china is so cheap
[00:50:02] <Valen> impatient and have a mill that will do it already lol
[00:50:06] <coors> yeah i can't wait either
[00:50:29] <coors> when i work on something i go through 5 revisions a weekend
[00:50:40] <coors> no way i wait 4 weeks to get my stuff per revision
[00:51:04] <coors> but it's usually small modular project i use at work
[00:51:15] <Valen> this is what we use on our mill
[00:51:16] <Valen> http://www.ebay.com.au/itm/2-2KW-WATER-COOLED-MILLING-AND-GRINDING-SPINDLE-MOTOR-WITH-2-2KW-INVERTER-VFD-r2-/390375010406?pt=AU_B_I_Electrical_Test_Equipment&hash=item5ae429f066&_uhb=1
[00:51:20] <coors> so just 4x4" boards and such
[00:51:24] <Valen> it cuts stainless steel OK
[00:51:57] <coors> wow that's cheap
[00:52:02] <coors> it includes the vfd
[00:52:09] <Valen> they are putting $150 on it in the postage
[00:52:14] <coors> whats the runout on that thing?
[00:52:22] <Valen> not a great deal
[00:52:29] <L84Supper> Runout off: less than 0.005mm
[00:52:30] <Valen> its what cut those pcbs lol
[00:52:36] <Valen> sounds about right
[00:52:44] <coors> yeah that's pretty nice
[00:52:54] <coors> for $400 i could live with that
[00:52:56] <Valen> probably double that in the real world lol
[00:53:05] <Valen> for a light mill I'd get an 800W one
[00:53:11] <coors> 10 microns is still good enough
[00:53:17] <Valen> the bearings in them (in ours) were done wrong
[00:53:24] <coors> if i can do 0603 resistors without a headache i'd be happy

[00:57:33] <coors> so i just let it go
[00:57:36] <coors> that was maybe a week ago
[00:57:42] <L84Supper> he travels to China few times a year to get parts
[00:57:58] <coors> thinking about it, that makes a lot of sense
[00:58:09] <coors> so you think he is alright and doesnt scam people?
[00:58:12] <L84Supper> he has the same problems we do
[00:58:22] <L84Supper> QC issues with Chinese parts :)
[00:58:40] <coors> hehe
[00:58:44] <coors> i can only imagine
[00:58:50] <L84Supper> I can just show up and pay him cash
[00:58:59] <coors> where are you from? chi?
[00:59:00] <jdh> I've bought things from him with no problems
[00:59:20] <L84Supper> I'm ~30 minutes from him
[00:59:23] <coors> hmm, maybe i shoudl reconsider the 4530 or the next one up
[00:59:48] <coors> i got friends living in lakeville, so i could go there on a weekend
[00:59:55] <L84Supper> he just has a warehouse full of boxes of automation parts from China
[01:00:00] <coors> doesnt look like i can make it on time during the week though
[01:00:04] <L84Supper> and one person that fills orders

[01:02:34] <L84Supper> I'm also in China half the time
[01:02:35] <coors> anyways, i am wondering about the keiling dude now
[01:02:54] <jdh> that is the keling dood

[01:03:06] <L84Supper> I only eat and drink in the city

[01:04:25] -!- ssi [ssi!~ssi@app2.prototechnical.com] has joined #linuxcnc
[01:04:52] <coors> so what does your cnc look like though?
[01:05:05] <coors> it sounds like you do metal for the most part?
[01:05:15] <L84Supper> I have to talk to him about more Linuxcnc vs mach3
[01:05:43] <coors> hmm, i just got started out with mach3
[01:05:52] <coors> but i dont think it's bad

[01:06:09] <coors> would be nicer if it was open source, but it works for me i suppose
[01:06:16] <L84Supper> I'm more on the research end, additive manufacturing, materials science, nanotech
[01:06:20] -!- the_wench has quit [Ping timeout: 256 seconds]
[01:06:31] <coors> oh that's funny
[01:06:42] <coors> i'm in materials
[01:06:57] <coors> more on the physics/chemistry side though doing a lot of laser stuff
[01:07:29] <coors> basically nanoscale semiconductor materials and characterization of those
[01:07:33] <L84Supper> inks, fluids, coatings, photopymers for SLA, SLA, DLP, inkjet, micronozzle, aerosol jet etc etc
[01:08:00] <L84Supper> printed electronics
[01:08:12] <coors> so you are a little more applied and i'm way on the basic side
[01:08:26] <L84Supper> we are printing pcb's with only fluids, board + conductors
[01:08:27] <coors> but same field
[01:08:40] <L84Supper> yeah, we have to get it into production
[01:08:48] <coors> is that some electrostatic thing?
[01:09:02] <coors> i am thinking kinda like a laser printer
[01:09:17] <L84Supper> laser and jet
[01:09:50] <coors> sounds interesting, is it gonna be cheap? :)
[01:09:54] <L84Supper> the core and prepreg is a fluid
[01:10:20] <L84Supper> not just printing conductors on FR4
[01:10:39] <coors> what's a prepreg?
[01:10:56] <L84Supper> lower cost and faster than plating, etching, drilling , milling laminating....
[01:11:07] <L84Supper> the board
[01:11:25] <coors> so you expose it or do something else to harden it?
[01:11:39] <coors> it sounds a bit uncommon to me
[01:12:00] <coors> i guess big question is can you do multilayer boards cheap as well
[01:12:19] <L84Supper> multilayer is more like multiwire
[01:12:28] <L84Supper> no drilling for vias
[01:12:39] <coors> so yours is real 3D "printing"
[01:12:45] <L84Supper> so denser boards and it's faster
[01:12:58] <coors> that's cool
[01:13:08] <coors> are you a ME or EE?
[01:14:05] <L84Supper> started way back as a EE, now I actually do more chemistry than anything else :)
[01:14:38] <coors> cool, i started as a chemist and moved to physics
[01:14:52] <coors> seems to be the typical way people move though
[01:15:01] <L84Supper> all this stuff crosses over
[01:15:07] <coors> well, at least for physical chemistry
[01:15:26] <L84Supper> I have to brush up on Biology to work with the tissue printers
[01:15:30] <coors> yeah, even though physics is still superconductors and low temperature stuff
[01:15:35] <coors> at least the more traditional part
[01:15:57] <coors> well, i hope you learn bio faster than i do
[01:16:16] <coors> i am having a hard time memorizing pictures, so that is clearly not for me
[01:16:32] <L84Supper> the cnc controls are pretty straightforward, same for the mechanical/automation
[01:16:46] <L84Supper> the real work is in the materials
[01:16:55] <coors> that cheers me up a bit
[01:17:05] <coors> i am completely lost with the mechanical part here
[01:17:11] <coors> trying to figure out what that's all about
[01:17:25] <coors> chemistry/circuitry/programming is easy
[01:17:50] <coors> i know i can just etch my pcbs, but i am trying to force me to get that cnc thing done
[01:17:57] <L84Supper> the more you know the better and you also find out how much you really don't know
[01:17:58] <coors> since i am already invested into it
[01:18:14] <coors> yeah i totally agree
[01:18:31] <coors> i feel like my biggest issue is that i don't have a mill/lathe at home
[01:18:39] <coors> well, and limited money obviously
[01:18:44] <L84Supper> but it's hard to find people that can cover more than one discipline
[01:18:56] <coors> i think if i spent $5k on a cnc, i'd be a dead man
[01:19:19] <L84Supper> look for used
[01:19:36] <coors> that is used for those emco machines i mentioned
[01:19:47] <coors> but they are precise and there is nothing to worry about
[01:19:52] <L84Supper> craigslist in chicago has lots of sherline and similar machines all the time
[01:19:59] <coors> i'm just not ready to take that hit on my crappy salary
[01:20:13] <coors> i saw those, but are sherlines any good?
[01:20:21] <coors> i thought they are like those grizzly ones
[01:20:34] <coors> the best one of those appeared to be the one from littlemachineshop
[01:20:44] <coors> but even that one i'm not sure about
[01:21:01] <coors> my problem is that i don't know enough about what specs to really look for
[01:23:05] <L84Supper> hang in here and cnczone you'll find out soon enough
[01:24:47] <coors> yeah that's what i've been doing so far
[01:25:03] <coors> i think i picked up quite a bit so far
[01:25:23] <coors> at least my first cnc actually cut something
[01:25:29] <coors> so that's a pretty good start

[01:26:06] <coors> well, i guess i gotta troubleshoot a stepper driver thing i bought for lab
[01:26:20] <L84Supper> ^^ here's that setup with the acme
[01:26:21] <coors> got one from pololu, but i don't think it works quite right
[01:27:00] <coors> oh you use minitec or 80/20?
[01:27:44] <L84Supper> those were 80/20 since it was around xmas and Steiner had it in stock same day in 4m lengths
[01:27:45] <coors> i was thinking about that
[01:27:56] <coors> you like em?
[01:28:11] <coors> i am just using aluminum squares from the hardware store right now
[01:28:16] <L84Supper> not pretty but they work
[01:28:22] <coors> that's why i need a new gantry i think
[01:28:32] <coors> it's got too much twisting action to it
[01:29:14] <coors> your "gantry" has 4 screws to it doesnt it?
[01:29:51] <coors> just a 1/2" aluminum plate there isn't it?
[01:30:00] <coors> or maybe even 1/4"
[01:30:09] <L84Supper> 3/8 6061
[01:30:13] <coors> i need to find a mill to make those
[01:30:17] <L84Supper> 3/8 x 4"
[01:30:45] <coors> hehe, right in the middle
[01:31:20] <coors> i think i can get scrap aluminum cheap, just gotta find a mill i can use
[01:31:26] <L84Supper> ordered everything the same day
[01:31:38] <coors> oh, you get those cut already?
[01:31:44] <L84Supper> the aluminum was from metal Superstores
[01:31:45] <coors> speedymetals or where from?
[01:32:08] <L84Supper> well in lengths, then I finish them on a mill
[01:32:54] <L84Supper> still the nice thing about Chicago, i can drive in a circle and pick most parts up the same day
[01:32:57] <coors> that's what i figured
[01:33:18] <coors> i need to ask you about places to go soon
[01:33:29] <L84Supper> metal, t-slot, automation, power supply ....
[01:33:54] <coors> oh, there is a store in bolingbrook
[01:34:00] <coors> i've been to that ikea
[01:34:03] <coors> :)

[01:35:23] <L84Supper> there are still a few mills in the city if you want full plates or full lengths of shapes
[01:35:39] <coors> so they cut em to size and drill holes for you?
[01:35:48] <L84Supper> sorry, Villa park, next door

[01:37:03] <L84Supper> they only guarantee 1/16" accuracy on cuts
[01:37:18] <coors> problem is that i am not sure i wanna buy one of those $700 mills to get it done
[01:37:39] <L84Supper> so i just order what will fit in/on the truck
[01:37:51] <coors> so you buy it slightly larges and square everything yourself?
[01:38:18] <L84Supper> yeah
[01:38:21] <coors> are you using a mill at your company or did you get one yourself?
[01:38:36] <L84Supper> same thing
[01:38:44] <coors> i coudl use one at the university, but i can only get on it during work hours
[01:38:55] <coors> and that usually makes my boss quite unhappy

[02:26:06] <coors> i was just trying to figure out how they work
[02:26:10] <L84Supper> a few post docs, mostly just hacker types
[02:26:23] <L84Supper> mostly 30 and under
[02:26:33] <coors> i appreciate you being so nice
[02:26:45] <coors> is rhys one of their main guys though?
[02:26:49] <L84Supper> now you know why i left

[02:27:54] <coors> well, i'd go out of my way to have a good time and learn things for sure

[02:29:27] <coors> do you mind telling a bit more?
[02:29:42] <coors> i mean i would pay a monthly membership fee just to go once
[02:30:01] <coors> and i might as well go to fort wayne instead which seems to be older folks 50+
[02:30:17] <coors> but there i'd have no place to crash on weekends
[02:30:31] <L84Supper> they asked me what i wanted to build and why i was there, I said that I already have a lab and i was just in search of intelligent life

[02:32:11] <L84Supper> check out the website
[02:32:27] <coors> yeah i saw some conductive thread things
[02:32:34] <L84Supper> the beer project is very popular
[02:32:58] <L84Supper> most of the complex things are by one member
[02:33:04] <L84Supper> he's on the board
[02:33:27] <coors> is that pdb?
[02:33:47] <L84Supper> pdish
[02:34:11] <coors> is that all the nerp things?
[02:34:16] <coors> those look most interesting to me
[02:34:21] <L84Supper> Jordan developed an open source silver conductive ink
[02:34:30] <coors> but i can't quite wrap my head around the structure
[02:34:35] <L84Supper> he left, he used to be with the U of I
[02:34:57] <coors> that's the one west of the loop, isnt it?

[02:35:17] <L84Supper> one of the founders is a Chemist but now he's learning to code
[02:35:19] <coors> or is that the same place?
[02:35:32] <L84Supper> yeah same school, different locations

[02:36:01] <L84Supper> U of I in down in Champagne
[02:36:22] <coors> uiuc?
[02:36:54] <coors> they got a lot of stuff that's similar to what i do
[02:37:09] <L84Supper> there's also a hackerspace in Milwaukee and Madison
[02:37:09] <coors> i see, all of this is not far from my "network"
[02:37:18] <coors> yeah, that's too far up
[02:37:26] <coors> even though i got a friend at madison
[02:37:38] <L84Supper> amtrack to Milw
[02:37:39] <coors> but there is no way i can go there every weekend
[02:37:48] <L84Supper> tough commute
[02:37:52] <coors> not just time, but also money
[02:38:06] <coors> 4h + $40 round trip at least
[02:38:24] <coors> that's like $250 a month without a place to stay overnight
[02:38:36] <coors> so chicago/fort wayne is probably what i can do
[02:39:53] <coors> oh well, i am not sure what to do

[02:52:15] <L84Supper> so a project from scratch vs build on EMC again
[02:53:26] <L84Supper> another atmel cnc controller project
[02:53:31] <jdh> heh
[02:53:56] <L84Supper> reprap AVR stuff
[02:56:56] -!- Mikegg has quit [Ping timeout: 252 seconds]
[02:57:32] <bzzzz> what's wrong with uc cnc controller projects?
[02:58:05] <jdh> nothing
[02:59:30] <L84Supper> they just tend to poorly reinvent the wheel
[02:59:46] <L84Supper> not that there's anything wrong with that
[02:59:47] <bzzzz> can you expound on that?
[03:00:03] -!- RangerRick has quit [Remote host closed the connection]
[03:00:05] <bzzzz> a bit too lazy to google around for existing projects
[03:00:28] <L84Supper> ever see the code behind reprap?
[03:01:36] <jdh> uC is limited... if you are strictly bound by size and cost, you have to deal with the limitations
[03:01:50] <bzzzz> well leave it for the simple hard realtime things, obviously
[03:02:07] <jdh> so, just offload the RT stuff to the uC
[03:02:17] <L84Supper> now there are reprap control boards that have 32b ARM controllers that cost as much as an old PC + mesa
[03:02:22] <jdh> which has its own problems
[03:02:53] <bzzzz> last time i checked, which was a few years back, mesa goes for 100+
[03:03:08] <L84Supper> http://smoothieware.org/smoothieboard
[03:03:40] <bzzzz> oh wow, looks just like that pic32mx sk
[03:03:44] <L84Supper> and you still need a PC for CAM
[03:03:49] <jdh> if you can do it with a uC, you most likely don't need mesa HW, it just makes it nicer.
[03:03:56] <bzzzz> yeah, exactly
[03:05:24] <L84Supper> https://0xfb.com/shop.html
[03:05:27] <bzzzz> the 1769 is nice as hell on the dtasheet but i could run it under a debugger last time
[03:06:36] <bzzzz> L84Supper: the smoothie is 140, isn't that still cheaper than a mesa?
[03:07:24] <L84Supper> it dropped to $140, thats more like it, it was ~$200
[03:07:37] <L84Supper> it could be ~$60
[03:07:47] <jdh> my router pc cost $140
[03:08:00] <L84Supper> I need to float those schematics around china
[03:08:05] <jdh> dual core atom
[03:09:06] <L84Supper> mini-itx AMD or Atom boards are as low as $50, the new mesa PCIe fpga board is ~$60
[03:09:32] <L84Supper> then you just need the IO
[03:10:43] <bzzzz> jesus h, 168 euros
[03:11:12] <bzzzz> in any case, i'm not sure how easy it woul be to port emc to run bare metal
[03:11:21] <bzzzz> i've been out of the loop for a while
[03:12:07] <L84Supper> it runs on arm9 and the RPi
[03:12:45] <L84Supper> https://www.youtube.com/watch?v=w3Ls5ta7eg8
[03:13:00] <bzzzz> got a text link? i cn't watch flvs
[03:13:12] <L84Supper> also the Beaglebone
[03:14:46] <bzzzz> Short answer is no, the main thrust of LinuxCNC is still running NC machines on inexpensive computers, rather than trying to create embedded systems or find a way of using restricted low power boards.
[03:15:26] <L84Supper> also http://code.google.com/p/miniemc2/
[03:15:51] <L84Supper> on an ARM920T CPU running at 400 MHz
[03:17:04] <bzzzz> that's a microprocessor, not a microcontroller
[03:17:28] <L84Supper> potato potato
[03:17:44] <L84Supper> where do you draw the line, lack of MMU?
[03:17:44] <bzzzz> the difference is that with a uc, you coul use a hardware timer to generate your ticks
[03:18:03] <bzzzz> instead of running into realtime delay errors or whatnot
[03:18:12] <bzzzz> uc is way more deterministic
[03:18:25] <L84Supper> http://www.newegg.com/Product/Product.aspx?Item=N82E16813157324
[03:18:36] <L84Supper> $54.99
[03:18:41] <bzzzz> meh
[03:18:48] <bzzzz> see above
[03:19:11] <bzzzz> the impetus is to avoid a uprocessor
[03:19:14] <L84Supper> 4us latency jitter for $55
[03:19:34] <L84Supper> and a GPU to run the UI
[03:19:48] <bzzzz> haha, that's funny
[03:19:54] <bzzzz> the gpu just accelerates rendering
[03:20:04] <L84Supper> so an FPGA would be best
[03:20:15] <bzzzz> what would be cool is to use the rpi's gpu for motion control calcs
[03:21:09] <L84Supper> one big state machine
[03:21:30] <bzzzz> yeah, and state machines are filled with what?
[03:21:33] <L84Supper> software just gets in the way
[03:21:40] <bzzzz> conditionals
[03:22:06] <bzzzz> iirc, fpgas are terribad for conditionals, just like gpus
[03:22:27] <L84Supper> your just a lazy hardware engineer
[03:22:32] <bzzzz> and ucs hve gotten so efficient that they can handle stepgen on their own
[03:22:32] -!- joe9 has quit [Read error: Connection reset by peer]
[03:22:45] <bzzzz> so i really don't know if fpgas have a plce in the motion control world
[03:22:45] <L84Supper> you use software as a crutch
[03:22:51] <bzzzz> hah
[03:23:03] <bzzzz> let's compile gcc into a netlist, right?
[03:23:40] <L84Supper> C is for the weak of mind
[03:23:42] <bzzzz> seriously, using luts for state machines is like sending an army of shiny drones into the sun
[03:23:54] <L84Supper> just give me 1's and 0's
[03:24:15] <bzzzz> are you a vhdl/verilog guy?
[03:25:33] <L84Supper> not when I'm mixing polymers, but i still prefer to design and pack gates by hand in fpga's
[03:26:04] <Connor> anyone around good with gladevcp ?
[03:26:57] <bzzzz> chemical engineering?
[03:26:58] <L84Supper> but vhdl/verilog come in handy when I'm only using 50% of the gates available
[03:27:25] <bzzzz> laziness is good, that's my last free advice of the day
[03:28:18] <L84Supper> my mom says i have to resort my sock drawer anyway
[03:28:55] <L84Supper> g'night

[03:42:18] <pcw_home> Theres no much serious motion control without FPGAs
[03:43:22] <L84Supper> take it with a grain of salt
[03:43:27] <pcw_home> Used In all high end drives
[03:46:30] <pcw_home> and getting more integrated and migrating lower as time goes on
[03:46:40] s1dev is now known as defcadbot_
[03:47:05] defcadbot_ is now known as s1dev

[03:48:35] <L84Supper> i just looked at this again, they also are spellbound by the RPi and repraps
[03:48:55] -!- AR_ has quit [Ping timeout: 240 seconds]
[03:49:09] <L84Supper> you can buy $500 Scara's that will do a much better job
[03:49:43] <L84Supper> but no, these 20's somethings have a better idea
[03:52:32] <pcw_home> I do think that M Haberlers 'MachineKit' idea is a good future LInuxCNC direction
[03:52:34] <pcw_home> since hardware capable of running a RTOS/HAL and communications are getting
[03:52:36] <pcw_home> close to a single chip and memory
[03:53:29] <L84Supper> oh the A31 kernel tree and reference schematics are out
[03:53:43] <L84Supper> same pinout as the a10 but 4 core
[03:54:28] <pcw_home> The cubieboard will have a A20 varient (I think the A31 is different)
[03:55:22] <L84Supper> a31 is quad cortex a7
[03:55:48] <pcw_home> Yeah but I think it has a different pinout
[03:56:46] <L84Supper> a10 and and a20 same pinout
[03:57:24] <pcw_home> Yes (though A20 may need a heatsink at 1 GHz+)
[03:57:53] <pcw_home> just about done with my cubieboard FPGA card
[03:58:37] <L84Supper> $30 in parts gets you quad >1ghz ARM and 2GB DDR3 and all the IO
[03:59:59] <L84Supper> interested to see how this all works out
[04:00:01] <pcw_home> For industrial things the question might be for how long, however
[04:01:20] <L84Supper> any news on Zynq?
[04:01:24] <pcw_home> I expect that even volumes like the RPI are not too interesting to the cell phone chip manufacturers
[04:01:34] <L84Supper> wondering where the final price will be
[04:02:40] <pcw_home> No new info I need to contact Xilinx since thats my next task
[04:02:42] <pcw_home> Altera has some competitive parts so that will help
[04:02:56] <L84Supper> force their hand
[04:03:32] <pcw_home> and the parallela thing still claims to be $100 and they have moved up to a 7020
[04:03:57] <pcw_home> (after talking to Xilinx)
[04:05:16] <L84Supper> I'd like to see a non Broadcon RPi type board
[04:05:52] <L84Supper> cubie had no funding
[04:05:55] <pcw_home> your strobe question a few days ago got me interested in a LED strobe so I bought a 60W LED to play with
[04:06:12] <L84Supper> heh, i noticed
[04:06:20] <L84Supper> i just wanted to buy vs build
[04:06:32] <L84Supper> I don't have time to build everything
[04:07:04] <pcw_home> I was reading that 10 ns pulses are possible with blue
[04:07:32] <pcw_home> phosphor lifetime limits white to > 1 usec or so
[04:07:35] -!- joe9 has quit [Remote host closed the connection]
[04:07:43] <L84Supper> 3 months ago I paid $30 for 1 W 405m leds, last week I paid $3 for 3W 405m leds
[04:08:13] <Jymmm> 3W LEDs ?????????????????
[04:08:16] <pcw_home> Yeah I see more an more LED street light around here
[04:08:27] <L84Supper> unless you're trying to capture over 1M fps that should good
[04:08:49] <Jymmm> LED street lighting is nasty for EMI/RFI output
[04:09:15] <L84Supper> PWM the street lights?
[04:09:44] <L84Supper> 405nm leds ^^
[04:10:01] <L84Supper> prices are dropping like rocks
[04:10:44] <Jymmm> L84Supper: no clue
[04:11:03] -!- joe9 [joe9!~user@c-71-236-20-61.hsd1.ga.comcast.net] has joined #linuxcnc
[04:11:41] <pcw_home> You get diminishing returns with more than say 3x normal current in pulses for
[04:11:43] <pcw_home> strobe use but starting with a 60 W LED you have a lot of visible light at even
[04:11:45] <pcw_home> 0.1% duty cycles and no high voltage and completely programmable on time
[04:12:05] <L84Supper> http://universal-led.en.made-in-china.com/product/KSXJvyfBEQhz/China-Power-LED-Chips-UN-HP-80W-.html
[04:12:16] <L84Supper> pcw_home: did you order something similar
[04:14:17] <L84Supper> http://www.ledfedy.com/
[04:15:32] <pcw_home> Yes 60W

[04:17:09] <L84Supper> they list these as strobe LED's http://www.ledfedy.com/products/5mm-strobe-led/5mm-hyper-strobe-led/c-127/
[04:18:01] <L84Supper> but i think they meant flashing and color changing

[04:18:36] <pcw_home> Yeah strobe in the disco sense
[04:20:25] <L84Supper> strobe + digital microscope on the spindle
[04:21:09] <pcw_home> I found out about white LED phosphor decay time in a apaper about modulating white
[04:21:11] <pcw_home> LED room lighting at 10 MBPS for network comms

[04:21:55] -!- Connor [Connor!~Connor@] has parted #linuxcnc
[04:22:01] <L84Supper> yeah well it's phosphor
[04:22:19] <L84Supper> it doesn't have to be white light
[04:22:41] -!- Connor [Connor!~Connor@] has joined #linuxcnc
[04:23:00] <pcw_home> I was going to get blue but big blue LED arrays are less common
[04:23:42] <Connor> it possible to use a gladevcp LED as a signal output ?
[04:24:18] <pcw_home> probably not fast enough for a strobe light
[04:24:22] <Connor> Setting up a group of buttons that are grouped toggether.. you press one and it toggles on.. you press another it toggles all the other off and toggles itself on.
[04:25:08] <pcw_home> Dont know, the gladevcp people are probably asleep
[04:25:35] <L84Supper> http://www.alibaba.com/product-gs/615620332/50w_420nm_led.html might make a faster strobe
[04:25:45] <pcw_home> and mentioning that make me sleepy
[04:26:35] <pcw_home> yes for more exotic uses (down to 10 ns or so)
[04:26:56] <pcw_home> 'nite

[11:53:28] <ProxDem> yes but the IP method will not always work
[11:53:36] <ProxDem> if the server is using VirtualDomains
[11:53:40] <DJ9DJ> hm k
[11:53:47] <ProxDem> and if it is and you went via the Name and then the IP
[11:53:50] * DJ9DJ is not network specialist
[11:54:00] <ProxDem> the server recognizes you and defaults to your last Domain Name based request
[11:54:15] <jthornton> can't find server name for address
[11:54:23] <jthornton> default servers are not available
[11:54:27] <jthornton> \server: unkown
[11:54:32] <ProxDem> jthornton: then your box that is acting as your DNS is br0ken
[11:54:42] <DJ9DJ> seems that you have no dns :D
[11:54:47] <jthornton> need to reboot them?
[11:54:54] <ProxDem> I would reboot yes
[11:54:56] <ProxDem> or
[11:55:05] <ProxDem> you can specify opendns or your ISPs dns directly in your configs
[11:55:45] <ProxDem> in linux it's in /etc/resolv.conf
[11:55:50] <ProxDem> nameserver IPofyourDNS
[11:56:10] <ProxDem> or just reboot the router and hope it's DNS functionality just for some reason b0rked
[11:56:17] <ProxDem> jthornton: only one down side to rebooting your router
[11:56:26] <jthornton> easier to just reboot everything, I have 5 linux computers and 2 windoze computers
[11:56:30] <ProxDem> if your DNS is b0rked and rebooting doesn't work
[11:56:35] <ProxDem> you will not be able to come back here
[11:56:50] <R2E4_awy> restart the dns
[11:57:06] <R2E4_awy> bind or whatever he is runing
[11:57:09] <ProxDem> if his routers DNS capabilities are f00bared
[11:57:18] <ProxDem> and all his machines use that as a DNS server
[11:57:23] <ProxDem> he will not be able to come back here for more help
[11:57:29] <jthornton> would that be a hardware issue?
[11:57:37] <ProxDem> I would make sure you have at least one machine that has either your ISPs DNS or OPENDNS
[11:57:39] <DJ9DJ> adams.freenode.net is
[11:57:40] <DJ9DJ> ;)
[11:57:48] <DJ9DJ> just 4 the case
[11:57:54] <ProxDem> or as DJ9DJ mentions the IP of one irc server
[11:58:03] <ProxDem> and hope to god it doesn't try to redirect you
[11:58:14] <ProxDem> via domain name redirection
[11:58:32] <ProxDem> jthornton: some routers can crap out overtime on their DNS services
[11:58:40] <ProxDem> rebooting usualy fixes that
[11:58:47] <ProxDem> or switching to dd-wrt =P
[11:58:55] <ProxDem> I for one
[11:59:00] <ProxDem> never use router based DNS
[11:59:10] <ProxDem> I prefer to have them set in the invididual machines
[11:59:21] <jthornton> I'm not following all the DNS stuff :(
[11:59:24] <ProxDem> some routers will let you set that up in the DHCP config
[11:59:37] <ProxDem> jthornton: for one...write down the IP of at least a few freenode servers
[11:59:47] <ProxDem> so that you can come back on here even if rebooting doesn't fix your DNS issues
[12:00:15] <ProxDem> 2...I would setup a linux box to have at the very least your ISPs DNS in it's /etc/resolv.conf

[12:02:42] <ProxDem> if you changed to (you'd be using googles opendns)
[12:03:16] <ProxDem> but be aware that on every reboot or DHCP renewal there is a very HIGH probability that the /etc/resolv.conf be overwritten

[15:07:53] <pcw_home> total hardware cost about $20 (for 60W LED and driver)
[15:09:25] <pcw_home> should just scale with bigger LED modules (and duty cycles would be so low that no heatsinking is needed)

[19:19:44] <Connor> PCW on Pete's setup, would changing the servo base thread from 1,000,000 to 500,000 make a difference with using the MPG on a Encoder input ?
[19:20:07] <PCW> no
[19:20:34] <Connor> ok. It's about 10' from 7i77 non-differential.
[19:21:20] -!- phillipadsmith_ has quit [Ping timeout: 260 seconds]
[19:21:24] <PCW> the problem with using hm2 encoder inputs for MPGs is that there is no 1X mode
[19:22:28] <Connor> When I'm back over to his house Saturday.. I'll run up hal config and see what the raw count coming from the MPG is..
[19:22:50] <Connor> What lines of code do I need to make it work with the MPG encoder input ?
[19:23:07] <PCW> The 7I77 supports a 1X mode on some of its digital inputs but 10ft is a long way for TTL signals
[19:24:13] <PCW> basically get the count from the 7I77 instead of the 5I25 (and you need to set the 7i77 mode so it has the MPG inputs)
[19:24:46] <Connor> yea. That's the part I know nothing about.
[19:25:33] <Connor> *IF* we continue to have issues.. I can do like Andy said and use the parport which is just a foot away.
[19:25:58] <PCW> I think on pncconf generated hal files the mode is set on the loadrt hm2_pci line
[19:26:23] <PCW> you can also use 4x mode but its not ideal if you want only one increment step per detent

[19:46:39] <Connor> ping = pins
[19:47:21] <PCW> no its a 7i77 remote so it will be like the I/O pins
[19:48:13] <Connor> okay, so how is it any different that just using the pins straight out without having to go into mode 3 ? I'm just a bit confused. Would be nice if they're was a example for this somewhere..
[19:48:30] <PCW> hm2_5i25.0.7i77.0.0.enc0 or similar
[19:49:11] <PCW> because its not bits but a count
[19:51:14] <PCW> also its slightly magic and uses a different input threshold (2.5V vs 1/2 VField)
[19:51:43] <Connor> ok. Trying to find the exact pin name for mpg 0 and mpg 1
[19:52:06] <PCW> halcmd show pin

[20:00:18] <Connor> Tom_itx: Ah.
[20:00:30] <Tom_itx> i just wondered where he got it

[20:07:29] <skunkworks> I am using a mpg hooked into the normal mesa encoder counters.. (and X4) I just have it scaled out so each click is movement/4 so .001 is actaully .00025 (Don't remember the specifics...)

[21:00:38] <ProxDem> 17years ago I started with slackware =)
[21:00:57] <jdh> I had SLS
[21:01:01] <jdh> then snackware
[21:01:37] <Connor> Slackware --> Redhat & SuSE ---> 1 Fedora --> CentOS for Servers ---> Ubuntu for Desktop
[21:01:51] <Connor> That's my progression..
[21:02:11] <jdh> I did Caldera while it briefly existed
[21:02:26] <ProxDem> that sounds like a regression =P
[21:02:39] <jdh> I still have a FC1 box
[21:02:57] <Connor> I have a application specific distro for a NAS box.. OpenFiler I think runs on a IDE DOM
[21:03:26] <ProxDem> going from slackware to repo based distros that's sad =)
[21:03:51] <Connor> ProxDem: No choice. Half the stuff I was using it for required a specific distro.
[21:04:02] <ProxDem> if it's not by choice I understand that
[21:04:19] <Connor> plus, I wasn't in it to tinker, I was in it to get things up and running. in a production environment.
[21:04:21] <ProxDem> I had to use centos for a few servers as well
[21:04:36] <andypugh> I have been on the web since about the first week.
[21:04:39] <Connor> I'm still running CentOS for servers..

[21:05:09] <ProxDem> some centos (no choice)
[21:05:35] <Connor> I played with FreeBSD and NetBSD some.. but.. never really used them.
[21:05:38] <Connor> stuck with linux.
[21:06:27] <ProxDem> bsd has it's advantages...pf has some tricks over iptables for example
[21:06:36] <ProxDem> but yeah stuck with linux
[21:06:43] <ProxDem> I prefer slackware been using it for 17years
[21:06:54] <jdh> you don't get out much, do you.
[21:06:54] <ProxDem> I do use ...eugh...ubuntu...and centos
[21:07:18] <ProxDem> jdh: is that a reference to my slackware usage?
[21:07:23] <jdh> yes :)
[21:07:26] <ProxDem> hum
[21:07:44] <ProxDem> a joke pertaining to the NON repo nature of slackware?
[21:07:48] -!- wboykinm_ has quit [Remote host closed the connection]
[21:08:12] <ProxDem> not sure how to interpret your joke
[21:08:16] <jdh> no, pertaining to the fact that it was just a pain for a few years.
[21:08:26] <ProxDem> it was never a pain for me
[21:08:29] -!- chillly has quit [Quit: Leaving]
[21:08:32] <jdh> you should interpret it as being witty and topical, regardless of its actual humor value.
[21:08:43] <ProxDem> so I'm not sure I understand your joke
[21:08:56] <jdh> that's ok.
[21:08:58] <ProxDem> is it because you like REPO based distros?
[21:09:10] <ProxDem> and simply want to yum install world?
[21:09:15] <ProxDem> or apt-get install world
[21:09:34] <jdh> never joke with idealists, they don't understand.
[21:10:03] <ProxDem> mk...so now we're making assumptions I'm an idealist?
[21:10:08] <DJ9DJ> gn8
[21:10:16] <ProxDem> all that because I'm trying to understand what your joke is based on?
[21:10:27] <jdh> indeed.
[21:10:30] <ProxDem> seems a tad far fetched if you ask me
[21:10:36] <jdh> that's ok.
[21:10:59] -!- DJ9DJ has quit [Quit: bye]
[21:11:17] <ProxDem> actualy I find that kinda lame
[21:11:20] <ProxDem> not "ok"
[21:11:31] <ProxDem> I haven't assumed anything about you...yet
[21:11:39] <jdh> that's ok too.
[21:12:00] <andypugh> Guys, why not just let this drop?
[21:12:05] <jdh> ok
[21:12:39] <jdh> I didn't like slackware in 1996ish and moved on.
[21:12:48] <andypugh> Instead, tell me how the heck to actually get a file from my Mac share to my Ubuntu machine. SO I can machine it.
[21:12:55] <jdh> bluetooth?
[21:13:06] <ProxDem> andypugh: scp
[21:13:12] <R2E4_> I started with Slakware
[21:13:14] <Tom_itx> andypugh if all else fails pastebin it :D
[21:13:46] <andypugh> I have been gnown to gmail stuff to myself.
[21:13:52] <Tom_itx> me too
[21:13:59] <Tom_itx> sometimes it's faster
[21:14:06] <Connor> I email stuff yo myself all the fracking time..
[21:14:16] <Connor> and ftp it to a remote host and back down.
[21:14:20] <jdh> I know people happily using samba shares on macos
[21:14:53] <andypugh> Yeah, I have samba/cifs shares setup and zerconf/bonjour/avahi.
[21:15:47] <jdh> I have a disk on my router/wap/thing that I mount on my winboxes and my cnc boxes.
[21:15:52] <andypugh> And I can push files from the Mac to the Ubu machines. And I can navigate the folders and _see_ the files in the shares from the Ubu machines, but whenever I try to open or copy a file I get a "Not supported" error.
[21:17:21] <andypugh> I just pushed the file with AFP. But I don't like doing that as it puts nasty invisible Mac files everywhere.
[21:17:24] <ProxDem> you could use scp to copy the files from the mac to ubuntu
[21:17:44] <t12> anything in the samba logs?
[21:17:49] -!- FinboySlick has quit [Quit: Leaving.]
[21:17:56] <t12> or the osx logs for that matter
[21:18:04] <Connor> Why can't I re-home in my simulator.. I always get Cannot home while share home switch is closed..
[21:19:00] <jdh> scp + ssh-agent would be clean?
[21:19:08] <andypugh> The problem is that I typically want to "pull" when logged into the Ubuntu box. Otherwise it is a case of going out to the garage, unlockiong it, booting the CNC machine, locking the garage, walkking back round the house, pushing the file, walking back round the house, unlocking the garage...
[21:19:24] <andypugh> Connor: I had that today too.
[21:19:28] <jdh> I don't turn mine off
[21:19:50] <Connor> just use a thumb drive to move files back and forth and be done with it? :)
[21:19:57] <t12> dropbox?
[21:20:11] <jdh> google drive
[21:20:22] <t12> nfs
[21:20:34] <jdh> DECnet
[21:20:37] <ProxDem> sshfs
[21:20:52] <jdh> gmailfs
[21:21:32] <Connor> is they're a way to use the simulator so I can configure stuff up for 5i25 and 7i77 ?
[21:21:38] <Connor> without having them in the machine ?
[21:21:43] <t12> x.400
[21:21:50] <andypugh> Connor: Jog to a Z position less than 2 "units"
[21:22:12] <andypugh> Looks like a problem with the simulated home switches
[21:23:44] <andypugh> And yes, I believe you can run pncconf without the hardware connected.
[21:23:53] <Connor> I've done that.
[21:24:08] <Connor> I just want to start tweaking it and making sure it loads.. but.. it won't.
[21:24:28] <Connor> so, I'm guessing the answer is no. not without the hardware.
[21:24:42] <andypugh> Ah, no, the config won't load.
[21:24:52] <Connor> Pncconf only gets you so far.
[21:25:00] <andypugh> All the pions will be missing.
[21:25:15] <andypugh> And the muons. (I meant pins, actually)
[21:25:31] <Connor> I read decent typo. :)

[21:46:06] <andypugh> I don't think it is a Mac problem, it seems to be a Ubu SMB problem
[21:47:16] <ProxDem> andypugh: skim through the smb logs?
[21:47:29] <andypugh> Where do they live?
[21:48:38] <ProxDem> should be in /var/log/samba/
[21:49:08] <andypugh> empty folder..
[21:49:30] <ProxDem> andypugh: are you mounting the samba shares or are you using konqueror or something similar?
[21:49:58] <andypugh> I really don't know.
[21:50:24] <andypugh> I am not even entirely sure I am using samba. I might be using afp..
[21:50:41] <andypugh> I am locating the share by gui-means
[21:51:51] <ProxDem> andypugh: can you elaborate on that a little bit?
[21:52:23] <andypugh> Places->Network->IMAC->CNC_drop
[21:52:46] <andypugh> The share appears in .gvfs.

[22:39:17] <Tom_itx> i know nothing about mac
[22:39:42] <andypugh> I don't think it is a Mac problem, but it could be, I suppose.
[22:39:44] <Tom_itx> but it's a sharing or file attribute issue of some sort
[22:40:14] <andypugh> I don't even know what file sharing protocol is being used.
[22:40:44] <Tom_itx> can you copy files the other direction?
[22:41:09] <andypugh> Yes, no trouble at all. (other than the amount of walking involved)
[22:41:26] <Tom_itx> what happens if you rename one of those copied files and copy it back?
[22:41:36] <andypugh> Hmm?
[22:42:01] <andypugh> Rename it on which machine, and copy it back to which machine?
[22:42:12] <Tom_itx> copy a file to the mac, rename it and try to copy it back to ubuntu
[22:42:33] <Tom_itx> just to see
[22:43:01] <andypugh> Not getting what you mean.
[22:43:24] <Tom_itx> you're trying to copy mac files to the ubuntu box right?
[22:43:29] <andypugh> Yes
[22:43:34] <Tom_itx> and they can't be accessed
[22:43:38] <andypugh> Yes
[22:43:58] <Tom_itx> so try to copy a file TO the mac machine. rename that file. try to copy it back to the ubuntu machine
[22:44:06] <andypugh> So, you are saying copy a file from the Ubu machine using the Mac?
[22:44:13] <Tom_itx> that will tell you it's a file attribute or file locking error or some type
[22:44:21] <Tom_itx> yes
[22:44:25] <Tom_itx> then copy it back
[22:44:39] <andypugh> Using which machine?
