[00:01:44] <DaViruz> maybe i wasn't entirely clear, the idea was to have an encoder with a hollow shaft that fits over my 28mm hollow shaft

[00:02:02] -!- FinboySlick [[email protected]] has joined #linuxcnc
[00:02:57] <andypugh> Ah! I thought you only had 28mm to play with!
[00:04:56] <DaViruz> it's for my lathe spindle
[00:05:16] <andypugh> So, cheap would be good too?
[00:05:46] <DaViruz> it would help
[00:06:05] <DaViruz> the heidenhein $3500 one is a little bit over the top
[00:06:14] <DaViruz> http://www.wallacecompany.com/cnc_lathe/HNC/00010-1a.jpg
[00:06:21] <DaViruz> i'm kind of liking that solution though
[00:08:08] <andypugh> I made my own.
[00:08:19] <andypugh> Is it for threading, or indexing?
[00:08:27] <DaViruz> threading
[00:08:34] <andypugh> (for threading in LinuxCNC you don't need all tha many slots
[00:09:06] <DaViruz> my lathe was built fron scratch by an old dentist, there realy isn't any good place to place an open windowed wheel
[00:10:03] <andypugh> Ah, so http://www.ebay.com/itm/Woodlathe-indexing-system-for-1-inch-spindles-/360288173252?pt=LH_DefaultDomain_0&hash=item53e2d93cc4 is not going to help?
[00:11:09] -!- zzolo has quit [Quit: zzolo]
[00:11:30] <andypugh> Belt-drive to a conventional encoder seems pretty common, that's what Hardinge do too.
[00:12:12] -!- racycle has quit [Quit: racycle]
[00:12:19] <DaViruz> i don't think i'm going to use linuxcnc for this though
[00:12:39] <DaViruz> i just want synchronized z feed
[00:12:51] <DaViruz> seems a bit overkill
[00:13:58] <skunkworks> DaViruz: but cheap and already done :)
[00:14:18] <skunkworks> I would use linuxcnc for everything if I could
[00:17:04] <r00t4rd3d> L84Supper, source?
[00:18:31] <DaViruz> yeah i know it works good, but i don't really want to tie the lathe up to a computer i have to boot just to use it, i still want to use it strictly manually
[00:19:14] <DaViruz> it can't be that complicated to have a microcontroller output pulses synced and scaled to incoming pulses
[00:20:07] -!- scottman_ has quit [Quit: Konversation terminated!]
[00:26:42] <andypugh> DaViruz: No, I think there are widgets that do it. Integer maths might not be enough, beware of rounding errors.
[00:27:58] <andypugh> If you used servos then you could still use the lathe manually. (I have steppers on mine, and I can only turn the manual handles slowly)
[00:29:47] <DaViruz> oh? i ordered a stepper with dual shafts thinking i'd be in the clear
[00:30:35] <DaViruz> does it cause too much "drag" even unpowered?
[00:30:49] <andypugh> It might depend on the drives.
[00:31:01] <andypugh> Open-circuit they twirl freely.
[00:31:29] <DaViruz> oh.
[00:31:50] <DaViruz> i'll have to check and see how my other steppers on geckos handle
[00:31:59] <andypugh> It doesn't stop you turnign the handles, it just feels a bit odd.
[00:34:37] <andypugh> Night all

[01:05:20] <Jymmm> nah
[01:06:23] <L84Supper> use racks of them with flashing LED's for a 1960's supercomputer look
[01:06:37] <Jymmm> lol, there ya go!
[01:06:50] <Jymmm> But I have smoked acrylic for that =)
[01:07:22] <L84Supper> how did it taste? :)
[01:07:39] <Jymmm> The beans and rice? Great!

[01:31:35] <MattyMatt> DaViruz I'm making an encoder exactly the same (except 30mm spindle)
[01:32:23] -!- Wildhoney has quit [Ping timeout: 240 seconds]
[01:33:12] <MattyMatt> turned flanged wheel, with drilled holes, and 2 single optos , +1 for index
[01:33:46] <MattyMatt> I'm still looking for ones deep enough to let me have the index hole on the same wheel
[01:34:56] <MattyMatt> not very high res I guess

[03:09:57] <pfred1> whoohoo a new PC for LinuxCNC!
[03:10:17] <Jymmm> lol
[03:10:36] <pfred1> I scored a HP Pavilion a6130n at a thrift store today for $5
[03:11:20] <pfred1> it has a Athlon 64 X2 (B) 5000+ 2.6 GHz (65W) in it that should be better than my 1GHz P3
[03:11:34] <Jymmm> burn in test it for a week
[03:13:37] <pfred1> I like to live dangerously

[03:18:28] <L84Supper> :)
[03:18:34] <pfred1> I got a swivel stool here I can sell to you for a lot
[03:19:03] <Valen> pfred1: stick a drill motor onto it
[03:19:44] <pfred1> man don't anyone ever run Linux Mint 14 the stuff will drive ya to drink!
[03:21:24] <skunkworks> tjb1: is that yours?
[03:21:33] <tjb1> yes
[03:22:03] <skunkworks> cool - what are you doing for kins?
[03:22:08] -!- pfredx1 [[email protected]] has joined #linuxcnc
[03:22:15] <pfredx1> my new junker PC
[03:22:23] <skunkworks> linuxcnc?
[03:22:54] <skunkworks> or the reprap whatever control
[03:24:50] <L84Supper> it looks like I'll have to add the vision interface for orientation and calibration to EMC http://psha.org.ru/b/camview-emc.html is a nice start
[03:24:56] <tjb1> ramps
[03:27:20] <L84Supper> http://pimicos.com/ is in Germany, so it should cost more and take longer. bingo!
[03:27:37] <pfredx1> L84Supper you know what Vince said
[03:27:47] <pfredx1> the Germans always make good stuff!
[03:27:58] -!- sparklehorse has quit [Ping timeout: 245 seconds]
[03:28:24] <pfredx1> with the slap chop you'll be slapping your troubles away
[03:28:54] <L84Supper> "if we only has more time we could have won" as we used to say
[03:29:56] <L84Supper> well... my parents friends anyway
[03:30:12] <pfredx1> I'm stoked to latency test this PC
[03:31:00] <L84Supper> pfred1: our similar boards have all been under 10uS, if not 5uS
[03:31:21] <pfredx1> L84Supper for an HP?
[03:31:32] <L84Supper> building for Gentoo + RTAI
[03:31:50] <L84Supper> Athlon 64 X2 and similar
[03:31:58] <pfredx1> I don't know i may just drop in the CD and go on this one
[03:32:26] <pfredx1> I did a custom install on my P3 and it took a lot of time
[03:32:57] <pfredx1> but on the latency chart page these old X2s seem to clock pretty good
[03:33:12] <L84Supper> now that the new RTAI is out we'll post some generic kernel building howto's
[03:34:17] <pfredx1> I have some strategies for building kernels
[03:34:43] <pfredx1> model name : AMD Athlon(tm) 64 X2 Dual Core Processor 5000+
[03:34:52] <pfredx1> smokin!
[03:37:21] <pfredx1> they had another PC at that thrift store I should go pick it up tomorrow
[03:38:22] <L84Supper> I have some old AMD K6/3d 366's I could send you
[03:38:43] <pfredx1> older than athlon?
[03:38:48] <L84Supper> 256mb ram and 10gb hd's
[03:39:03] <L84Supper> must be from 98 or so
[03:39:15] <pfredx1> this thing has a 400GB HDD in it it is from 2007
[03:39:50] <pfredx1> in 98 I had an 800MHz athlon thunderbird
[03:39:55] <L84Supper> 99-00 iirc
[03:40:24] <pfredx1> it was the chip that came out before the K6 I think
[03:40:31] <L84Supper> you were livin big
[03:40:56] <pfredx1> well I wanted the 1 Ghz but it was so much money I took the middle of the road one
[03:41:11] <pfredx1> I ran that PC for 10 years
[03:41:25] <pfredx1> then the PSU went on it and killed all of the caps on the motherboard
[03:41:44] <pfredx1> I went to it one morning and it was a brick
[03:41:49] <L84Supper> June 5, 2000 The second generation Athlon, the Thunderbird, debuted
[03:42:00] <pfredx1> yeah I had the first gen one
[03:42:16] <pfredx1> but I could swear it was called a thunderbird
[03:42:23] <L84Supper> Athlon processor launched on June 23, 1999
[03:42:29] <pfredx1> maybe it was the 2nd gen one?
[03:42:53] <pfredx1> let me see i have it right here
[03:43:13] <L84Supper> K6-2 was an x86 microprocessor introduced by AMD on May 28, 1998
[03:43:25] <L84Supper> http://en.wikipedia.org/wiki/AMD_K6-2
[03:43:47] <L84Supper> http://en.wikipedia.org/wiki/K7_(microarchitecture)
[03:44:00] <pfredx1> nope it must still be in that motherboard down in the lean to
[03:44:17] <pfredx1> I thought about recapping the board
[03:45:03] <pfredx1> but it would have cost me like $40
[03:45:32] <Valen> halfway to a new atom board there
[03:45:41] <pfredx1> not then
[03:46:30] <pfredx1> I ran a 2 GHz P4 I picked up at the dumps for a while
[03:46:55] <pfredx1> but it just got too slow so I bit the bullet and bought an i3
[03:47:05] <L84Supper> http://www.newegg.com/Product/Product.aspx?Item=N82E16813157324 $54.99
[03:47:22] <jdh> I ditched the dual athlon on my router for an atom
[03:47:23] <L84Supper> ASRock E35LM1 AMD E-240 APU AMD A50M Mini ITX Motherboard
[03:48:18] <pfredx1> to get that board to run you need RAM and a PSU
[03:48:41] <pfredx1> oh and some kind of storage too
[03:54:49] <pfredx1> this is strange this machine won't read one of my flash drives

[04:58:48] <L84Supper> does anyone make a complete 5 axis rotary table? 500mm x 300mm x 100mm min
[04:59:19] <pfred1> what is that in English?
[04:59:41] <L84Supper> let me know what part you need translated
[04:59:51] <pfred1> 500mm x 300mm x 100mm
[05:00:28] <L84Supper> that would be the travel of the 3 main axis
[05:00:55] <L84Supper> since 4 and 5 are rotary
[05:01:25] <pfred1> we don't use the metric system in America
[05:01:36] <L84Supper> really
[05:02:08] <pfred1> we tried it in the 70s and it just didn't go over so well
[05:02:24] <pfred1> no one wanted to buy gasoline by the liter
[05:03:16] <L84Supper> I've been here for 50 years and I use it all the time, are you from the hills by chance? :)
[05:03:34] <pfred1> here where?
[05:03:48] <L84Supper> uhmerica
[05:03:49] <Connor> pfred1 you would be surprised at how much our non-metric stuff has influenced stuff though..
[05:03:50] <pfred1> you show me where we post speed limits in anything other than miles per hour
[05:03:55] <L84Supper> uhmerika
[05:04:14] <pfred1> or sell gasoline in anything other ghan gallons
[05:04:17] <L84Supper> merika for short
[05:04:52] <pfred1> the only thing they use metric for in this coutnry is selling dope
[05:05:03] <pfred1> oh and soda
[05:05:08] <Connor> pfred1 I didn't say that.. Lots of metric stuff is really just inch converted because it's so wide spread..
[05:05:37] <L84Supper> pfred1: don't you have any contact with the rest of the world?
[05:05:58] <pfred1> I went to Canada once
[05:06:00] <Connor> pfred1 and several places have the Speed limit in both..

[07:20:23] <Loetmichel> moin
[07:20:55] <Loetmichel> ups... mornin' !
[07:21:42] <pfred1> hi
[07:21:51] <pfred1> I'm all excited I got a new PC
[07:22:15] -!- Simooon [[email protected]] has joined #linuxcnc
[07:22:25] * nevyn was there.. then uefi...
[07:23:09] <pfred1> well it is new to me it isn't a new PC though it is from 2007
[07:23:33] <pfred1> but hey I only paid $5 for it so
[07:24:59] <nevyn> YAY!
[07:25:09] <pfred1> now i see why people hated vista so much
[07:25:15] <Valen> rofl
[07:25:51] <pfred1> this machine came with vista on it and I didn't think it was that god awful but this other one it is I mean there has to be something seriously wrong with it
[07:25:57] <Valen> (18:23:06) Valen: so, my super squeezy design is too small for 805's
[07:25:57] <Valen> (18:23:18) Valen: practically speaking how hard is it to use 402s?
[07:25:57] <Valen> (18:23:40) Valen: with mask for solder paste, do routed boards still work?
[07:26:09] <nevyn> oh man.. wait untill you see win8
[07:26:14] <Valen> its slow as crap
[07:26:20] <pfred1> I saw win8 at best buy
[07:26:25] <Valen> UAC sucks
[07:26:36] <nevyn> Valen: I know someone who does all their stuff in 0402 he's mad
[07:26:50] <Valen> nevyn: hrm?
[07:26:53] <nevyn> Valen: it was nessicary for the geometry of a particular rf bandpass filter to work.
[07:27:06] <Valen> i just have teensy space requirements
[07:27:16] <nevyn> how teensy?
[07:27:17] <pfred1> buy a bigger place
[07:27:23] <Valen> 20 components or so need to fit into 10mm x 15mm
[07:27:37] <nevyn> how many layers?
[07:27:39] <nevyn> 4?
[07:27:42] <nevyn> or just 2?
[07:27:46] <Valen> undefined at this stage
[07:27:53] <Valen> as many as are needed ;->
[07:28:10] <Valen> the layout with 805's is fairly simple it looks like it'll almost be one
[07:28:12] <pfred1> I don't do that high frequency stuff that is all touchy
[07:28:32] <pfred1> or try to make stuff so small it is hard for me to work with
[07:28:39] <Valen> the datasheet said the bypass cap needed to be within 20mm, DONE! lol
[07:28:41] <nevyn> so 402's by hand (for prototypes) is doable you really do want to have a good magnifier or preferably binocular microscope.
[07:29:08] <pfred1> when you get to be my age you'll need all of that just t oread the newspaper
[07:29:20] <nevyn> and at your part counts it shouldn't be too insane..
[07:29:23] <Valen> I was hoping to make the boards by hand in production
[07:29:37] <Valen> around 100 every 6 months or so
[07:29:53] <nevyn> not worth your sanity imho but doable.
[07:30:11] <Valen> otherwise its going to be using the mill and a sucker and some fancy pants G Code lol
[07:30:20] <nevyn> thaty's only placing 200 parts under a scope (~ 4hrs work based on my friends workrate)
[07:30:28] <Valen> how much easier are 603's?
[07:30:48] <Valen> 2000 parts for 100 boards with 20 components to a board
[07:30:54] <Valen> 805's are easy to do
[07:30:58] <nevyn> sure.
[07:31:04] <nevyn> 402's really arn't
[07:31:09] <pfred1> I assembled electronics at a board house for a while the works is pretty dull
[07:31:32] <nevyn> I've done 0804 and 1206 by hand with an iron.
[07:31:51] <nevyn> I wouldn't do 0402 but I've seen hand rework with an iron of 0402
[07:31:52] <Valen> frying pan works well for soldering ;->
[07:32:06] <nevyn> paste + fryingpan seems to be ok.
[07:32:16] <nevyn> turn it off once the board hits the reflow temp
[07:32:27] <nevyn> and let the thermal mass sort it out.
[07:32:28] <Valen> we do it on a gas stove
[07:32:36] <Valen> use a sheet of Al and sit the board on that

[07:33:08] <nevyn> we've had very limited success with toaster oven's
[07:33:13] <nevyn> in our hackerspace.
[07:33:45] <pfred1> roasting and toasting semiconductors just seems wrong to me
[07:33:47] <Valen> somebody on ebay has them cheap
[07:34:13] <pfred1> then again when my old boss told me to load a dishwasher up with PCBs we'd made i thought he was pulling my leg
[07:34:14] <nevyn> pfred1: how do you think it's done professionally?
[07:34:29] <nevyn> no caustic tho.. just on HOT.

[07:35:28] <pfred1> through hole or nothing!
[07:35:56] <nevyn> the problem with that is lots of interesting parts arn't availible in through hole anymore
[07:36:04] <archivist> my last production qty was through hole :)
[07:36:08] <nevyn> plus drilling fiberglass is a pain in the ass.
[07:36:15] <pfred1> the way I look at it is plenty of interesting parts still are
[07:36:23] <pfred1> nah i have a nice little drill press
[07:36:38] <pfred1> does 5,000 RPM
[07:37:02] <Valen> pfred doesn't want one of these then
[07:37:05] <nevyn> lots of sensors particularly are only SMD
[07:37:17] <nevyn> as well as lots of SOC's

[07:38:11] <Valen> I'm waiting for them to dump PCB's
[07:38:27] <Valen> you just get a bunch of wafer bits an ultrasonic welder and some gold wire
[07:38:34] <Valen> add epoxy when you're done
[07:38:36] <nevyn> BGA?
[07:38:42] <pfred1> ball grid array
[07:38:44] <nevyn> or bloby?
[07:39:16] <pfred1> nah DIP chips are what i like
[07:39:27] <nevyn> heh there was an interesting blog post by bunnie about the usb drives handed out at LCA

[07:43:01] * nevyn feels slightly stalked...
[07:43:23] <pfred1> don't flatter yourself
[07:43:26] * Valen hopes its a hot psyco chick
[07:43:54] <Valen> (i figure if your being stalked, odds are its a psyco anyway, so it might as well be a hot chick)
[07:44:07] <pfred1> all hot chicks are psychos
[07:44:09] <nevyn> maybe that's what the p stands for...
[07:44:21] <nevyn> hence the hot/crazy scale. ;)
[07:44:41] <Valen> nevyn: thats what daddy issues are for
[07:44:46] <pfred1> they know they'll find some guy that'll put up with their crap
[07:45:31] <Loetmichel> hrhr
[07:45:49] <Valen> also the definitive hot/crazy scale is more of a reference, the Vicky Mendoza Diagonal being the dividing line

[14:39:49] <ler_hydra> heyo! Long time since I've been here on the IRC channel. A quick question, I've been looking for PWM servo amplifiers without finding anything that I found really good. Does anyone here know of a decent amplifier? (I've looked at the pico systems amplifier, as listed on the wiki, but I didn't really get a good feeling by just seeing photos and a few sentences about it)

[15:20:42] <ler_hydra> haha, alright. Last time I was here that was one of the upcoming features, then again that was around 4-5 years ago... I'm guessing that just an encoder and a spindle control output are enough? (with some PWM output)

[16:47:09] <ler_hydra> jepler, I saw your PWM servo controller (etch CNC), looks nice! I'm toying with the idea of designing a general-purpose H-bridge (for, among other things, driving servos for linuxcnc). What are the limitations of the design you've used?
[16:47:45] <ler_hydra> Is it primary the motor speed, so that base thread can keep up with the encoder count? Or something else?

[16:49:32] <cradek> ler_hydra: if you're running it with parport pwm, your update frequency is so low that you'll only get 10ish useful magnitudes
[16:49:51] <ler_hydra> cradek, magnitudes? Of power level?
[16:49:55] <cradek> yeah
[16:50:15] <ler_hydra> oh, heh, 3.5 bit PWM depth sounds sort of so-so
[16:50:21] <cradek> and they're torque levels, not velocity, so they don't even work linearly
[16:50:28] <ler_hydra> exactly
[16:50:43] <cradek> you can use pdm to help a bit, but still, it's lousy
[16:50:59] <ler_hydra> or well, nonlinear torque, since parport PWM is duty cycle to the bridge which drives applied voltage
[16:51:10] <cradek> and polling the encoder lines is quite limited too
[16:51:13] <ler_hydra> hmm, which other methods are there to drive a servo amplifer?
[16:51:27] <L84Supper> tjtr33: Submersible, and Stainless Steel with electrical isolation, interesting
[16:51:28] <cradek> hardware pwm or hardware dac
[16:51:38] <ler_hydra> Is there support for some data (serial or parallel) transmission protocoll?
[16:51:50] <tjtr33> L84Supper, we got trunnions from them
[16:52:14] <L84Supper> tjtr33: my maximum load is 3Kg :)
[16:52:30] <cradek> each hardware driver does its own thing. some use EPP, some use port-mapped IO, some use SPI, etc etc.
[16:52:52] <tjtr33> L84Supper, look at off the shelf stuff from Hirschmann ( edm tooling ) for small payloads
[16:53:06] <cradek> heck I think some new stuff uses realtime ethernet packets
[16:53:12] <ler_hydra> right, I'm toying with the idea of rolling my own controller hardware with an embedded microprocessor taking care of PWM and encoder counts
[16:53:49] <cradek> you're sure not the first one to try that. I notice all the pros use FPGAs instead of microcontrollers.
[16:54:12] <L84Supper> tjtr33: and they are local
[16:54:17] <ler_hydra> yeah, I remember jepler's project (IIRC it was called pluto-p )
[16:54:53] <cradek> have you seen http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Emc2HardwareDesign
[16:55:31] <ler_hydra> a 4000 count encoder at 3000 rpm does give counts at 200khz, which is starting to get pretty high for a software based system, that only gives me 100 cycles at 20MHz
[16:55:34] <cradek> yeah pluto-p still works except the hardware is unfortunately crap
[16:55:44] <ler_hydra> overheating?
[16:56:11] <cradek> don't forget you not only have to count at that rate, you have to periodically communicate with your host, without losing count, too
[16:56:22] <ler_hydra> yeah, exactly
[16:56:59] <tjtr33> L84Supper, tell Pete Knowles Hiya from tomp http://www.hirschmannusa.com/PDF/H100ABR.NC.pdf
[16:57:00] <ler_hydra> I'm really just toying around with the idea, but I was considering a low-cost device with one uP per amplifier

[16:57:15] <cradek> I think it doesn't overheat - it works with very few parports - something about missing pullups/pulldowns? in summary, hardware made too cheaply and/or carelessly.
[16:57:17] <ler_hydra> so I "only" need to take care of one encoder and one H-bridge
[16:57:29] <ler_hydra> cradek, aww... that's too bad =(

[16:59:10] <ler_hydra> cradek, just for playing around with the thought, what's the "best" (from EMC's point of view) method of communicating data to/from external digital hardware? (I suppose I could duplicate parts of Jepler's pluto-P interface)
[16:59:25] <ler_hydra> (under the assumption of working over the parport)
[17:00:28] <cradek> IMO, a pci card
[17:00:42] <cradek> have you priced the mesa 5i25?
[17:01:26] <cradek> I think it's silly to make more EPP devices today. that ship really has sailed.
[17:01:27] <ler_hydra> hmm, I haven't honestly looked at them at all. I'd still need some power amplification though
[17:02:01] <cradek> sure, you could concentrate on the power part and not reinvent the wheel (and certainly not reinvent the square wheel)
[17:02:06] <ler_hydra> I know what you mean, it really reeks of designing for hardware thats vanishing fast
[17:02:28] <L84Supper> tjtr33: i was just looking at the H-80
[17:03:04] <cradek> the cheapest possible "power part" for simple/small servo setups would be a neat thing to have
[17:03:18] <ler_hydra> cradek, do you happen to remember a ballpark figure of cost for a 5i25?
[17:03:41] <L84Supper> tjtr33: whats the clearance around the rotary table, we need to center a part 370 x 300mm
[17:03:41] <cradek> no, but mesanet.com has a price list
[17:03:45] <ler_hydra> yeah, something like your driver but for more current and voltage
[17:04:02] <cradek> my driver? I used an L298 for my toy lathe
[17:04:10] <cradek> it's silly but it does actually work
[17:04:41] <ler_hydra> heh, that's pretty cute though
[17:04:53] <ler_hydra> 89USD for a 5i25 board, that's not bad at all
[17:04:56] <archivist> toy...a bit big for some of my parts
[17:05:37] <ler_hydra> and 160USD for their breakout board with DACs and encoder inputs
[17:06:10] <cradek> if you use pwm, you don't want or need dacs
[17:06:20] <L84Supper> whats the lowest cost method to build a 3 axis table with only 1.5" max of travel x,y,z and 0.05" accuracy
[17:06:48] <ler_hydra> yeah, just a bare-bones breakout would be the best for that
[17:06:57] <ler_hydra> well that's definitely one option
[17:07:03] <tjtr33> L84Supper, we had custom made, MMK is good, but expensive. I had a 24" cubic volume originating at TDC, after my fixture clamped to trunnion
[17:07:12] <L84Supper> was thinking about making it all from plastic
[17:07:42] <tjtr33> L84Supper, production or prototype?
[17:07:57] <L84Supper> tjtr33: some like Haas are ~$50K for the range of travel + clearance but the loads are for something 100x what I need
[17:08:34] <L84Supper> tjtr33: production, was thinking about printing it all with SLA
[17:08:57] <L84Supper> tjtr33: 2 different projects by the way :)
[17:09:41] <tjtr33> L84Supper, submerged or maybe inverted over a tank? dunno, is that why you looked at pi's hexapod?
[17:10:06] <ler_hydra> is the parport too slow for effective serial data transfer? When toying around with the idea I was thinking about making it useful for many other embedded situations, so an SPI-driven H-bridge board with encoder inputs would be a pretty handy little thing. IIRC a base thread is around 40�S, and the servo thread is around 1ms? If so I would guess I can get 25 pin changes per servo thread, IE about 3 bytes of data. That would seem like en
[17:10:06] <ler_hydra> ough to transfer a PWM setpoint and the number of encoder counts since the last read, right?
[17:10:09] <L84Supper> tjtr33: somebody else posted the hexapod
[17:10:41] <L84Supper> tjtr33: I'm just looking at trunion + rotary table
[17:10:53] <ler_hydra> Actually, I have more than that, I'd have around 3 tx bytes and 3 rx bytes
[17:11:47] <tjtr33> L84Supper, then for small and precise, the edm tooling mfctrs are good Erowa Hirschmann 3R ( and all the companies the Geo Fischer bought up )

[17:26:54] <ler_hydra> yep, mostly I was wondering becuase I'd like to have a robust and powerful H-bridge board in my back pocket for whatever application I could need to use one, and for other applications a serial data interface would be useful
[17:27:19] <ler_hydra> so I'd need to check if (for simplicity's sake) a parport could be used to drive that output

[18:13:17] <AR_> do you guys wire all your limit switches in series or do you have them individual?
[18:14:03] <pcw_home> HAL crashing is very likely _not_ related to encoders/drives/following errors
[18:17:08] <andypugh> AR_: In series if short of inputs, otherwise individually
[18:17:31] <JesusAlos> maybe the hardware PC?
[18:17:54] <pcw_home> If you think you have an encoder problem, I would do multilpe long moves and verify that the position does not creep. For tuning I would go through JTs velocity tuning tutorial http://gnipsel.com/linuxcnc/tuning/servo.html
[18:19:23] <tjtr33> L84Supper, the sink edm tool manipulated by these trunnions is usually graphite, weighs grams, not kg, and small, inside a 150mm cube. so it maybe of use, of course you know your needs best.
[18:19:47] <pcw_home> Its possibly a PC problem but if its PC hardware, I would expect other things to crash not just HAL

[19:16:54] <ler_hydra> cradek, hey again. (here come some more newbiw questions) what is your opinion on closing the servo loop outside of EMC2? IE. external hardware that manages the entire control loop, only recieving incremental step changes
[19:19:56] <cradek> my opinion is that's another square wheel people like to invent for some reason I don't understand
[19:21:47] <cradek> (and it's been debated at length so so many times)
[19:22:07] <ler_hydra> heh, my line of thought (which is not very well thought through at the moment) is that it might be a good idea to have a general purpose H bridge / servo motor controller available for, well, among other things CNC control. The overhead isn't that bad --- implementing the controller isn't very difficult, and it's more than possible to output various status pins, like a fault status and so on.
[19:22:18] <cradek> I always wonder what problem exactly are you trying to solve by doing that. you have to sacrifice a lot of things.
[19:22:25] <ler_hydra> what are the downsides that you know of?
[19:23:04] <cradek> dangit, sorry, I'm busy and shouldn't have responded to such an involved question when I didn't have time, bbl
[19:23:34] <ler_hydra> well, the next time I would need a power H-bridge/servo controller (which is something that does appear for me every now and again) it would be quite straightforward and easy to get ahold of
[19:23:40] <ler_hydra> haha, sure, np
[19:24:35] <ler_hydra> I'm sure this is a question that appears time and time again, with no general answer to be had and lots of arguments
[19:24:49] <andypugh> Why put the clerverness in the drive when you have a multi-GHz CPU just sat there aching do fun Floating Point Calcs for you?
[19:25:18] <ler_hydra> well, a latency of 20us is pretty significant
[19:25:29] <ler_hydra> at least when it comes to driving PWM and counting the encoder transistions
[19:25:39] <ler_hydra> s/latency/system tick
[19:25:57] <andypugh> In a machine with (probably) 50Hz bandwidth? I don't think it is.
[19:26:27] <andypugh> And I don't think many of us advocate software PWM and encoder counting in a servo system.
[19:26:55] <ler_hydra> well, if I want to drive a servomotor with 8 bits of resolution at 25khz I need a rate of 200khz , or 5u
[19:27:08] <skunkworks> ler_hydra, mesa interface boards are really quite cheap...
[19:27:27] <skunkworks> pwm, step, encoder counting all done in hardware.
[19:27:34] -!- Thetawaves_ has quit [Quit: This computer has gone to sleep]
[19:27:45] <skunkworks> The loop is closed in linuxcnc so following error and tuning is all done in one place.
[19:28:18] <ler_hydra> there's a lot of benefit in closing the loop around the control system, definitely =)
[19:30:10] <Connor> I consider anything that closes the loop at the driver and not at the controller (linuxcnc) to be a "hybrid" closed loop system.
[19:30:21] <ler_hydra> FWIW it's also somewhat of a hobby that's fun to play around with, and if that hobby manages to make something that's usefull, then all the better
[19:30:53] <skunkworks> sure. though you should spend time improving the core of linuxcnc instead. ;)
[19:31:14] <ler_hydra> ;)
[19:34:49] <Tom_itx> andypugh, spin any brass yet?
[19:35:11] <ler_hydra> (sorry to just barge in here and rehash all these basic questions time and time again)
[19:35:17] <skunkworks> I spend a good part of a year creating a pwm servo amp to then find some on ebay for cheap. :)
[19:35:18] <Tom_itx> that aluminum didn't look too bad
[19:35:24] <skunkworks> found
[19:35:37] <skunkworks> ler_hydra, that is ok.
[19:35:43] <skunkworks> you had the emco lathe - right?
[19:35:49] <ler_hydra> oh, i'm not doing it for the money, far from it
[19:35:59] <Tom_itx> i'm gonna pull the motor control and motor from the washer and try to interface it
[19:36:06] <Tom_itx> it's some type of serial interface
[19:36:34] <ler_hydra> skunkworks, that's right, way back when. Still have it, though I'm planning to retrofit it again. Later on I'm hoping to get a mill too, where I'd like to have servo drives
[19:36:45] <skunkworks> ler_hydra, neither was I. I just could not find inexpensive drives for my system
[19:37:10] <ler_hydra> the first time around I had just started EE and didn't really know what I was doing, there's so much I'd do differently now
[19:37:25] <ler_hydra> skunkworks, what type of PC interface where you going for?
[19:37:37] <skunkworks> ler_hydra, I finished up my conversion since then..
[19:37:48] <skunkworks> pwm.
[19:38:00] <skunkworks> I was making dumb drives for emc
[19:38:06] <ler_hydra> oh ok
[19:38:49] <skunkworks> ler_hydra, http://www.youtube.com/watch?v=39q6kvrSBSk
[19:39:03] <skunkworks> (I really should make some newer videos
[19:39:09] <ler_hydra> I didn't quite figure out how difficult or feasibile it would be to have some good data interface over the parport. I know it's old, but it's relatively common and if not else cheap(er) than a "real" card
[19:39:26] <skunkworks> some use EPP
[19:39:27] <ler_hydra> I would think that something like SPI over the parport should be fast enough
[19:39:45] <ler_hydra> that's pretty big hardware!
[19:40:14] <skunkworks> that is why initally I tried to make some drives... I needed 20+ amps at 200+v
[19:40:35] <ler_hydra> isn't EPP just an I/O (and maybe speed) definition?
[19:40:47] <ler_hydra> hmm, that's quite a lot of power
[19:41:05] <skunkworks> I found some amc drives - 40a 400v analog
[19:41:11] <ler_hydra> not bad
[19:41:34] <skunkworks> epp is a comunication protocal over the printer port
[19:41:50] <ler_hydra> If I were to roll my own I was more aiming for around 50V and 20A
[19:42:24] <ler_hydra> both for servos as well as other loads (like a transformer in a forward converter for example)
[19:42:52] <ler_hydra> oh, including things like byte length, flow control, and so on?

[19:44:10] <skunkworks> ler_hydra, I don't know it that well.. ;)
[19:44:18] <ler_hydra> hehe, ok ;)
[19:45:04] <ler_hydra> for my case I'd like to be able to use something like SPI (a serial, clocked, interface), but adding support for a (IMO awful) step/dir/brake/fault interface would be easy
[19:56:58] -!- V0idExp [[email protected]] has joined #linuxcnc
[19:57:39] <ler_hydra> skunkworks, any idea if it would be feasible to have some clocked serial interface through the parport, that could set the drive duty cycle and read the encoder position?
[19:58:50] <ler_hydra> say a one byte header and one byte packet, the header signifying the content and the packet containing the data?
[20:05:42] -!- roh [[email protected]] has joined #linuxcnc
[20:07:32] <skunkworks> my gut says no - but that is above my paygrade.
[20:08:47] <ler_hydra> ok. for simplicity's sake I might just stick with the standard (though poor) step/dir interface, and only alert EMC2 on a fault condition
[20:24:41] <mrsun> hmm as alu has 1/3rd the stiffness of cast iron, if i make it 3 times as thick would it be as stiff as cast iron then ? :P

[20:52:43] <skunkworks> Yo mama's so fat - she uses step/direction servo interfaces!
[20:52:57] <JT-Shop> LOL
[20:53:19] <ler_hydra> I think it's mostly based on what you're comfortable with, as I don't code for PCs I'd rather integrate the smarts into an embedded device, and vice versa. When all you have is a hammer...
[20:53:24] -!- tmcw has quit [Ping timeout: 248 seconds]
[20:53:39] <ler_hydra> but I definitely agree that for this specific case it's far better to close the loop with EMC2
[20:54:14] -!- archivist_herron has quit [Read error: Operation timed out]
[20:54:29] <skunkworks> And - you don't have to 'code' for it to work in linuxcnc...
[20:54:33] <JT-Shop> what coding? you need to learn two words "net" and "setp" or just let the wizards set up your machine

[21:02:41] <andypugh> Tom_itx: Just had one failure and 1 success spinning the Pewter version.
[21:02:53] <andypugh> I am practicing the soldering on the failure. It's a challenge.
[21:03:20] <andypugh> ler_hydra: Yes, you can send dat through the parport. Google Mesa 7i43 and Pic PPMC
[21:03:43] <andypugh> Actually, as I can't type, let me do it for you:
[21:04:09] <andypugh> http://www.mesanet.com/pdf/parallel/7i43man.pdf
[21:04:21] <andypugh> http://pico-systems.com/PPMC.html
[21:04:31] <andypugh> Both compatible with LinuxCNC
[21:04:59] <Tom_itx> andypugh, how many times did you have to anneal it while spinning?
[21:05:10] <andypugh> None. No need with Pewter
[21:05:24] <ler_hydra> andypugh, ah, thanks!
[21:05:55] <Tom_itx> have you run the other one yet?
[21:06:04] <ler_hydra> looks like there's some specifications that define EPP, but the implemtation of data contents is up to the designer (much like RS232 for example)
[21:07:25] <andypugh> Tom_itx: No, I am trying to decide if I want to do it tonight, or wait for tomorrow.
[21:07:38] <Tom_itx> did you grab that update i posted?
[21:07:52] <andypugh> Just about to
[21:08:01] <Tom_itx> it might gouge the corner on the other one, i added a couple extra cuts on the beginning
[21:08:56] <Tom_itx> i think i'm gonna pull the motor and control from the washer. i finally gave up on repairing it
[21:09:06] <Tom_itx> maybe i can interface to it
[21:09:18] <Tom_itx> some type of serial interface for the speed control
[21:10:07] <Tom_itx> i think the new one has a F & P style direct drive motor
[21:11:05] <andypugh> I have an extra 8i20 to try running one of those motors :-)
[21:11:32] <Tom_itx> hopefully i can get enough of the control so i can put a scope on the signal
[21:11:41] <Tom_itx> or logic analizer
[21:11:47] <Tom_itx> if it's 5v signal

[23:53:20] <r00t4rd3d> yeah
[23:53:35] <andypugh> I _develop_ LinuxCNC on an 8GB SSD
[23:53:51] <ds3> I see.
[23:54:08] <ds3> getting tired of running EMC2 on a AMD K6-3 ;)
[23:54:47] <r00t4rd3d> better off with something intel
[23:54:59] <ds3> the AMD board was what i had lying around
[23:55:31] <ds3> does the stock 3D GUI work fine on the Intel D525DW board?
[23:55:38] <r00t4rd3d> ru in usa?
[23:56:12] <andypugh> ds3: Yes
[23:56:15] <r00t4rd3d> gui of what?
[23:56:23] <L84Supper> why is intel better?
[23:56:28] <ds3> forgot the name of it...there is a 3D GUI
[23:56:40] <r00t4rd3d> for linux?
[23:56:41] <ds3> it doesn't work for me on my current setup. I force it to use tkemc
[23:57:06] <r00t4rd3d> everything works just fine with a 525
[23:57:11] <L84Supper> "r00t4rd3d> better off with something intel" I was just wondering why
[23:57:14] <r00t4rd3d> linux, windows, etc
[23:57:46] <ds3> don't care about the vendor.. want a as simple as possible improvement so I cna be back to making chips
[23:58:28] <ds3> is there a Mini PCIE slot on the D525MW that I see?
[23:58:42] <r00t4rd3d> yeah
[23:58:52] <r00t4rd3d> you can get a ssd drive for it
[23:59:20] <ds3> nice.. I can reuse the old one from the eeePC
