[00:53:09] <Jymmm> archivist: Have you done photo etching of SS in quantities by chance?
[01:49:50] <archivist> Jymmm, no, I would just farm it out
[01:51:11] <Jymmm> archivist: Would you have a guestimate on cost per sq in of 0.015" SS etched in qty (lets say 100) ?
[01:52:22] <archivist> no, I would ask a company that does it
[01:53:22] <Jymmm> archivist: I have, it seems the cost (per sq in) is roughly the same as laser or waterjet is kinda why I was asking. Just trying to get a reasonable perspespective.
[01:54:38] <Jymmm> archivist: Even when I mention 10K and 50K quantities, the price isn't dropping dramatically.
[02:00:24] <DJ9DJ> moin
[02:09:03] <archivist> for high qty blanking is cheapest
[02:09:27] <Jymmm> archivist: on a punch press you mean?
[02:10:03] <archivist> yes, specially when that can include the bending
[02:10:27] <Jymmm> archivist: No bending involved, just flat sheet
[02:12:17] <BHSPiMonkey> ooh
[03:18:43] <mrsun> hmm sucks that encoders usaly are pow2 or what i should call it :/
[03:19:14] <mrsun> my steppers are 200 steps/rev, at 4 microsteps that 800 steps/rev .. the encoders i find are like 512 or 1024 point ... :P
[03:20:29] <mrsun> ofc there is these 200 pp encoders also on this page. .but then i would get 1 pulse/4 steps :p
[04:34:09] <Jymmm> Hi jepler
[05:06:54] <alex_jon1> hey Jymmm
[05:07:02] <alex_jon1> I doubt jepler's around at this hour
[05:56:49] <Loetmichel> mornin'
[05:57:11] <archivist> bit late for mining!
[05:57:15] <archivist> morning
[06:08:38] <Loetmichel> *grrr* *note to self: dremeling 20 miditowers with zinc plating without breathing gear: BAD idea... hat a bad case of (brass)Foundry fever yesterday evening. ... still have a headache of gigantic proportions :-(
[06:12:12] <Valen> you guys couldn't make cases rather than butcher those other ones?
[06:13:14] <Loetmichel> Valen. not for THAT price
[06:13:39] <Loetmichel> and we hanvent butchered them, just made the contact parts of the door metallic
[06:14:36] <Loetmichel> because Dell decided to put the paint over the contacts :-(
[08:31:36] <jthornton> how do you calculate the frequency of the charge-pump component
[08:39:18] <skunkworks> I would guess 1/2 period?
[08:39:25] * skunkworks likes guessing
[08:41:57] <archivist> depends!
[08:43:43] <JT-Shop> that was my guess kinda sorta, but I'd like to put the forumla in the manual...
[08:52:05] <archivist> it depends on the device you are connecting to
[08:52:21] <JT-Shop> how does it depend?
[08:53:50] <archivist> you are pulsing a filter if it is often enough the voltage will be above a threshold, what is the filters requirements (it is external)
[08:55:24] <JT-Shop> what I'm looking for is how do you calculate the output frequency of the charge-pump component based on the base period lenght
[08:55:24] <archivist> so depends on the R and C or you may have a minimum frequency given by the devices manual
[08:57:41] <skunkworks> yep http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=blob;f=src/hal/components/charge_pump.comp;h=3a612d1ae2a0a6313b24a8ab6f7df0947adc55c5;hb=HEAD
[08:57:46] <skunkworks> 1/2 period
[08:58:00] <skunkworks> out = !out;
[09:00:41] <archivist> point user at http://wiki.linuxcnc.org/cgi-bin/wiki.pl?About_Charge_Pumps for special frequencies etc
[09:00:41] * skunkworks watches JT-Shop and archivist talk past each other.
[09:00:49] <skunkworks> ;)
[09:01:26] <archivist> that page also tells one how to get one based on some other period
[09:02:01] * JT-Shop knows very little about how charge pumps work
[09:02:05] <archivist> more than one way of calculating needs
[09:02:21] <archivist> that wiki page seems to have enough info
[09:02:39] <JT-Shop> don't most drive give a min freq that the charge pump needs to turn on?
[09:02:46] <JT-Shop> yes it does
[09:02:52] <archivist> skunkworks, is jt asking the right question :)
[09:03:13] <JT-Shop> damifiknow
[09:03:22] * archivist giggles
[09:03:48] <JT-Shop> but I did find my answer on that wiki page
[09:04:34] <archivist> I do wonder at the islands of information without links to each other
[09:05:07] <skunkworks> heh
[09:05:19] <archivist> like this page http://linuxcnc.org/docs/html/hal/components.html
[09:06:05] <JT-Shop> that was an attempt to expose the 'hidden' man pages for components for the PDF readers
[09:06:15] <JT-Shop> and needs mucho work
[09:06:47] <archivist> I keep landing there and it is a dead end at the moment :)
[09:07:01] <skunkworks> cool - the wiki has a few example circuits..
[09:08:38] <archivist> I do wonder if manuals like say the php one where the page itself gets comment which can then be folded into the main doc (php has been slow at actually doing that though)
[09:12:24] <Jymmm> alex_jon1: Hi Alex; yeah I know, just being social (jut in case), he seems to be a ghost =)
[09:18:17] <JT-Shop> the post in question http://linuxcnc.org/index.php/english/component/kunena/?func=view&catid=38&id=24608#24614
[09:25:20] <steve_stallings> dead brain help please, what was the URL frequently recommended here for posting large files to be shared?
[09:26:12] <r00t4rd3d> https://anonfiles.com/
[09:50:07] <JT-Shop> filebin.something
[09:50:36] <jdh> reddit
[09:50:40] <jdh> oh, not those pics.
[09:51:15] <JT-Shop> this one works lol http://www.filebin.ca/
[09:55:21] <skunkworks> pcw_home, are you around?
[09:56:12] <skunkworks> logger[psha],
[09:56:12] <logger[psha]> skunkworks: Log stored at http://psha.org.ru/irc/%23linuxcnc/2012-09-25.html
[09:58:12] <skunkworks> pcw_home, (reading back) so you don't see a problem using the velocity estimate from the mesa encoder for a tach replacement back velocity mode amps?
[09:58:29] <skunkworks> *back to
[10:00:58] <pcw_home> No as long as theres enough phase margin, so for standard DC drive machine tool type of things its probably OK, though you may need to bump up the servo thread rate to a couple KHz
[10:02:05] <pcw_home> (so no Atom MBs if thats needed)
[10:05:22] <skunkworks> atoms can't go much above 1khz?
[10:05:36] <pcw_home> Nope
[10:06:45] <pcw_home> Not without real time warnings (which match my measure jitter of ~75uSec or so in the servo thread)
[10:06:56] <pcw_home> measured
[10:07:44] <pcw_home> My other test machine (an ancient Opteron) is OK with 6KHz
[10:08:09] <skunkworks> pcw_home, it is in reference to http://bbs.homeshopmachinist.net/threads/55882-CnC-programs-Turbo-Mach3/page10?highlight=linuxcnc
[10:08:17] <skunkworks> (about half way down and on_
[10:09:20] <skunkworks> Interesting. I have not played with atoms recently.
[10:11:56] <skunkworks> pcw_home, the newer asus motherboards that I tested.. I ran the livecd for a few days - the latency didn't go above 39k...
[10:12:33] <pcw_home> I suspect that theres something in the Atoms the blocks access to hardware (Video DMA maybe?) so a latency test that doesnt access hardware misses this
[10:14:45] <pcw_home> The thread numbers are available from HAL so a HAL comp that reported the max jitter would be nice
[10:15:05] <pcw_home> available to HAL I should say
[10:15:48] <FinboySlick> pcw_home: Are atoms ill affected when it comes to just stepgen too, or is that not demanding on the CPU at all? (sorry for not knowing much of what I'm talking about ;)
[10:18:23] <pcw_home> I'm not sure. The atoms base thread jitter look really good but I have not tested it.
[10:18:24] <pcw_home> I was just poking around with the servo thread to see why you cannot run faster than
[10:18:26] <pcw_home> about 1 KHz despite really good number in the latency test
[10:18:58] <FinboySlick> I'm just about to place an order for a 5I25 if you have some LP in stock.
[10:19:25] <pcw_home> (and the fact that MBs with much worse results in the latency test perform better)
[10:19:47] <pcw_home> I think they have both available
[10:25:57] <FinboySlick> pcw_home: And from our earlier talk, defining which pin does what is a matter of programming a custom firmware?
[10:27:04] <pcw_home> Yes all pins can do GPIO but special functions like step/dir or PWM are defined when the bitfile is made
[10:27:34] <FinboySlick> OK.
[10:29:39] <pcw_home> Theres a single file in the source that determines what modules are included (stepgen, PWMgen, encoder etc) and which pins these modules connect to
[10:35:34] <FinboySlick> pcw_home: Yeah, I remember giving you the specs for my setup, I just wasn't entirely sure why.
[11:01:44] <IchGuckLive> hi all from the stormy germany
[11:26:29] <amaldo> IchGuckLive: Not the best weather for Oktoberfest this year.
[11:26:45] <IchGuckLive> yeah
[11:56:46] <archivist> I do wonder if this cost that much new http://www.ebay.co.uk/itm/Webster-Bennett-TXE-1200-series-CNC-Vertical-Boring-and-Turning-Machine-/140853374537?pt=UK_Home_Garden_PowerTools_SM&hash=item20cb83ee49
[11:57:32] <tjb1> Todays work - http://sphotos-b.xx.fbcdn.net/hphotos-ash4/486735_4356896236561_145195399_n.jpg
[11:59:13] <mrsun> yeah! thats one thing to use 3d printers for ... alu casting patterns :P
[11:59:41] <mrsun> http://hackaday.com/2012/09/25/turning-3d-prints-into-aluminum-castings/
[12:04:09] <tjb1> I machined all of that, no casting :)
[12:05:13] <mrsun> no casting ?
[12:05:15] <mrsun> amature ...
[12:05:16] <mrsun> :P
[12:06:40] <tjb1> free billet, why cast? :P
[12:07:40] <tjb1> They put anything on hackaday...
[12:08:02] <tjb1> Put a fan in a nice painted box, add switch and here is this "showpiece of a fume extractor"
[12:08:59] <tjb1> Yeah lets see here…120mm fan, steel enclosure from digikey, painted with rustoleum hammered, and some wall wart in the back…thats super hard!
[12:09:43] <tjb1> Or some dingle welding plastic together with a plastic welder…oooohhh, thats hacking ;)
[12:09:53] <jdh> just poured $6.66 in to it!
[12:09:57] <jdh> <urk>
[12:11:11] <IchGuckLive> tjb1: the tread of your mashine isent trapezional isent it
[12:11:37] <tjb1> IchGuckLive: Hmm?
[12:12:33] <IchGuckLive> the photo you presented od the axis part
[12:12:42] <IchGuckLive> spindle tread
[12:12:58] <IchGuckLive> Why not trapeional
[12:13:23] <IchGuckLive> yheep and good speed also with 2way nut no backlash
[12:13:39] <tjb1> Why not trapezoidal?
[12:14:31] <tjb1> Is a trapezoidal lead screw = acme?
[12:15:54] <jdh> acme is a trapezoidal thread
[12:16:54] <tjb1> IchGuckLive: It is an acme screw
[12:16:59] <tjb1> With anti backlash nut on it
[12:23:13] <IchGuckLive> only to your knolige
[12:24:37] <tjb1> Only to my knowledge what?
[12:30:37] <FinboySlick> tjb1: I think IchGuckLive means that it could be a trapezoid thread that isn't technically acme.
[12:35:04] <andypugh> Acme is 29 degrees, DIN103 Trapezoidal is 30 degrres.
[12:49:48] <tjb1> The woman I buy steel from might be retarded..
[12:50:02] <tjb1> I need 11 gauge, "Well I think we have some 3/16 out in the warehouse"
[12:50:22] <tjb1> Thats .187", I need .090"
[12:50:36] <tjb1> "Well I can order 1/8"
[12:50:38] <JT-Shop> 11ga is not 0.090
[12:50:56] <Jymmm> Mayb that's what she was telling you they had that came the closest?
[12:51:01] <tjb1> according to browne and sharp it is
[12:51:18] <born2late> puh
[12:51:20] <JT-Shop> might be looking at a wire chart or something
[12:51:40] <JT-Shop> my steel sheet order book lists 0.090 as 13 ga
[12:51:46] <JT-Shop> 11 ga is 1/8"
[12:51:56] <born2late> is there some nice g-code editor around with a way to visualize the results ?
[12:52:01] <JT-Shop> but usually 0.120
[12:52:06] <JT-Shop> LinuxCNC
[12:52:08] <jdh> http://www.sheetmetalguy.com/sheet_metal_gauge_chart.htm
[12:52:40] <JT-Shop> oh you mean aluminum
[12:53:06] <mrsun> wtf
[12:53:10] <JT-Shop> odd how aluminum is different by 2 gauges
[12:53:14] <mrsun> different sizes for different gauages of material?!
[12:53:18] <tjb1> I didnt mean aluminum but I didnt see it didnt include steel
[12:53:24] <jdh> odd how people use 'gauge' vs. something useful
[12:53:31] <JT-Shop> reat the top column
[12:53:42] <mrsun> and i who didnt think that american stupidity could go any further then fractionals or wahtever its called :/
[12:53:43] <Jymmm> jdh++
[12:53:48] <JT-Shop> I use 11ga, 12ga, and 14ga all the time
[12:53:55] <tjb1> We very rarely use fractionals :P
[12:54:03] <tjb1> I deal in deicmel 99% of the time
[12:54:08] <jdh> I like 12gauge and 20gauge, the others seem pointless.
[12:54:20] <mrsun> and farneheit ... now america has sunk to a far far down new low :/
[12:54:27] <JT-Shop> 12 gauge is better, more knock down power
[12:54:28] <tjb1> $189 for a 6x10' sheet of 11 gauge steel, sounds good
[12:54:46] <tjb1> then I have to pay some guy $50 to bend it...
[12:54:59] <jdh> mrsun: is a human friendly measurement
[12:55:22] <mrsun> jdh, how ? when you got different thicknesses for the same guage number for different materials ...
[12:55:29] <mrsun> tell me exactly HOW that is human friendly :P
[12:55:41] * JT-Shop goes back to work
[12:55:41] <jdh> mrsun: I meant F. 0 is cold, 100 is hot.
[12:55:47] <Jymmm> mrsun: I think jdh meant F
[12:55:48] <tjb1> thats why you use deicmal and piss on gauge
[12:55:51] <mrsun> jdh, ahh =)
[12:55:56] <mrsun> no its not human friendly
[12:56:13] <Jymmm> mrsun: Well, neither are you damnit! =)
[12:56:17] <mrsun> 0 is water freezing, 100 is water boiling
[12:56:22] <mrsun> how is that not human friendly ? :)
[12:56:29] <mrsun> compared to F ...
[12:56:44] <tjb1> because you dont know F :)
[12:56:54] <mrsun> 212F ... well thats very ... well dragged out of the ass
[12:57:01] <jdh> 0 isn't very cold, and 100 is too hot to be useful (for humans)
[12:57:01] <mrsun> pulled
[12:57:35] <tjb1> How did it feel being pulled out of your ass? :D
[12:57:37] <mrsun> and as its not even a linear scale
[12:57:46] <mrsun> so how the heck can it be human friendly in any way
[12:58:12] <tjb1> 0-100c = 32-212f, you guys like decimals?
[12:58:20] <pcw_home> 100C at _atmospheric_ pressure is pretty arbitrary as well
[12:58:37] <IchGuckLive> O.O all alians here
[12:59:26] <IchGuckLive> i like 29Deg Celsius
[12:59:37] <IchGuckLive> and 1025 hpa
[12:59:51] <IchGuckLive> sunny side up ! B)
[13:00:10] <jdh> I like saltwater
[13:00:42] <IchGuckLive> on the skibnn ?
[13:00:49] <IchGuckLive> skin
[13:01:12] <IchGuckLive> maybe of your girlfriend also
[13:06:15] <jdh> on my skin, while diving in saltwater.
[13:07:31] <IchGuckLive> Hurgada egypt
[13:07:36] <IchGuckLive> nice
[13:10:42] <jdh> I'd think egypt might not be the best place for me to visit at the moment.
[13:11:16] <IchGuckLive> hurgada and sharm el shaik is friendly against foreners all countrys
[13:12:08] <jdh> someday, when there is peace through out the land, I will plan a trip to go diving there.
[13:12:21] <IchGuckLive> if you move to Asuan as USA maybe its tricky
[13:15:30] <andypugh> JT-Shop: 12-bore is a girls gun. http://en.wikipedia.org/wiki/2_bore
[13:16:12] <andypugh> born2late: You can visualise your G-code in the Axis preview.
[13:16:15] <JT-Shop> yes it is and my wife loves hers
[13:16:40] <andypugh> I think there are some other editors out there, but can't bring the names to mind.
[13:17:05] <IchGuckLive> by im off
[13:19:15] <andypugh> born2late: For Windows a quick Google just found http://www.cncsimulator.com
[13:20:41] <andypugh> There is also Cutsim, perhaps awallin can say how "ready" that is: https://github.com/aewallin/cutsim
[13:21:11] <born2late> cncsim : is so register crap
[13:21:21] <FinboySlick> I'm pretty sure the guys who make hsmwork have a standalone version of th gcode editor, which is extremely nice.
[13:21:33] <FinboySlick> It's probably expensive though.
[13:22:21] <born2late> i wanna have something to preview before going into the lab
[13:22:47] <FinboySlick> http://www.hsmworks.com/docs/hsmworks/2012/en/#Editor
[13:23:10] <FinboySlick> born2late: It's all I could find of it, but it gives you graphical preview and move simulation.
[13:24:13] <born2late> thx finboyslick
[13:24:14] <andypugh> born2late: You could install the sim version of LinuxCNC on your other computer.
[13:24:24] <born2late> hmm
[13:24:35] <born2late> no experience with the linux side of cnc
[13:24:41] <born2late> using mach3 atm with windows
[13:24:51] <born2late> no1 else looked into linux there atm
[13:24:59] <andypugh> It's just possible you are in the wrong IRC...
[13:26:10] <jdh> I think ncplot has a demo period
[13:26:49] <jdh> seems like it had g2/g3 weirdness though
[13:58:57] <tjb1> You looking for g code simulators?
[13:59:25] <tjb1> The g-wizard editor has a preview in it
[14:02:58] <r00t4rd3d> in all the vectric programs you can simulate the tool path and preview the results.
[14:08:13] <tjb1> r00t4rd3d: Did you get ksp
[14:09:50] <pcw_home> Wow if you live in the right part of Kansas city you can get Google fiber 1 GB up/down at $70.00 month!
[14:11:40] <r00t4rd3d> tjb1, ive played it on and off for years
[14:11:47] <tjb1> Its hard
[14:12:35] <r00t4rd3d> i never try and land on planets, just make rockets and blast them off :D
[14:22:50] <tjb1> lol
[14:22:59] <tjb1> Try to get the tracjectory right and hit mun lol
[14:23:06] <tjb1> and have enough fuel to do so!
[14:23:21] <r00t4rd3d> they have tons of plugins and add ons
[14:23:33] <r00t4rd3d> auto pilot and maps to pick destination etc
[14:24:01] <tjb1> thats too easy
[14:24:16] <r00t4rd3d> i use the rocket addons
[14:24:28] <r00t4rd3d> kw rocketry
[14:24:36] <tjb1> I added something but it took forever to load it then
[14:52:08] <mrsun> steels good for machining and making stuff from ? :)
[14:54:36] <tjb1> No I prefer paper
[14:55:03] <mrsun> that is, what steels :P
[15:04:27] <Tom_itx> http://www.ebay.com/itm/SANYO-DENKI-65BM030HBRSA-BL-SUPER-AC-SERVO-MOTOR-NEW-/271064899403?pt=LH_DefaultDomain_0&hash=item3f1cba1f4b
[15:09:58] <tjb1> $4 huh
[15:10:23] <tjb1> oh its a bloody auction
[15:18:05] <tom3p> JT-Shop, do you have frameworld prices? (catalog has none)
[15:19:50] <JT-Shop> tom3p: seems like you need to find a local supplier and get the prices from them, what's your local?
[15:20:46] <djdelorie> the only thing "local" to us here is cows...
[15:20:54] <tom3p> hah! (i hate salesmen) they're local elgin/lake in the hills illinois
[15:20:56] <tom3p> thx
[15:23:57] <tjb1> JT-Shop: Any comments on a 2" deep water table?
[15:36:55] <tjb1> Just when you think youve seen it all…an air filter on an electronics box
[15:36:56] <tjb1> http://www.cnczone.com/forums/attachment.php?attachmentid=14022&amp;d=1137788122
[15:39:10] <tom3p> is there any signal that marks the beginning of a servo period?
[15:41:44] <tom3p> or marks the start of any thread period
[15:45:04] <mrsun> hmm, outputs .. parport->outside world, is enough to have that buffered or should it be optoisolated?
[15:45:06] <mrsun> also inputs ?
[15:47:00] <FinboySlick> tjb1: You want a bigger fan on that heatsink, just for looks.
[15:47:32] <andypugh> tom3p: Not as far as I know. You could add one, I suppose.
[15:47:50] <tjb1> Thats not mine FinboySlick
[15:48:06] <tom3p> io thought of adding a one shot but cant suss what relation it would have to the thread timing
[15:48:23] <tom3p> andypugh, ^^^ (thx
[15:48:40] <andypugh> If you addf-ed one at the begining, and one at the end you might get something.
[15:49:41] <tom3p> thx, (clever!) will look into that
[15:50:23] <tom3p> i forgot/dis-remembered that addf had that possibility
[15:51:04] <andypugh> Maybe a pair of invert functions, with their inputs wired into each other could produce a scope-able square wave?
[15:51:49] <andypugh> No, not invert. I mean "not"
[15:52:03] <pcw_home> just one ( X <= not X)
[15:52:24] <tom3p> feeds itself?
[15:52:35] <pcw_home> negative feedback
[15:52:38] <andypugh> pcw_home: But you can't call the same function twice in the same thread.
[15:53:34] <andypugh> (I just tried :-)
[15:53:37] <pcw_home> You only need one call (unless I mis-understand)
[15:54:05] <andypugh> The idea was to get a square wave high at thread start, then low when it finishes. I think
[15:54:41] <tom3p> i dont have to have a sqr wave, i could edge detect, & just wire input to output ( i think thats pcw's idea)
[15:56:39] <tom3p> i was creating new velocities for a process (sensors not inside emc but moved by hal )
[15:57:00] <tom3p> and didnt want to spit out a new velocity mid-servo period or spit out many per period or... none for a few periods
[15:57:21] <pcw_home> If you are trying to get a output synced to the beginning of the thread its a bit awkward
[15:57:30] <DJ9DJ> gn8
[15:57:58] <pcw_home> (as the write part of I/O is done last)
[15:58:41] <pcw_home> a comp that writes directly to a parallel port would work however
[15:59:27] <tom3p> hows that different?
[15:59:56] <pcw_home> normal LinuxCNC thread order is read inputs do calcs write outputs
[16:00:10] <tom3p> yep
[16:00:57] <andypugh> Yeah, a simple comp with two functions, one to set the p-port high, and one to set it low.
[16:01:20] <pcw_home> as long as you are ok with that any I/O bit will be OK but if you want it done at
[16:01:21] <pcw_home> the beginning of the thread its more trouble
[16:02:02] <andypugh> Surely you just have to add that function first in the thread.
[16:02:22] <andypugh> There is no hard-coded requirement that writes come last.
[16:02:52] <andypugh> (Though you do get all sorts of comms faults if you addf hm2_write before hm2_read. DAMHIK)
[16:03:50] <tom3p> hahhah i had to lookup dont ask how i know
[16:05:32] <tom3p> off to play! thx again
[16:12:27] <tjb1> I have these little 4 inch linear slides with recirculating ball bearing trucks?, they have rubber pegs in the end mounting holes to keep it from sliding off. Whats the best way to keep it from sliding off when attached and not damage it?
[16:15:42] <JT-Shop> tjb1: comment on?
[16:15:52] <tjb1> 2" deep water table
[16:15:55] <tjb1> Too shallow?
[16:16:02] <bill1123> hi
[16:16:21] <JT-Shop> should be fine, how tall is your slats?
[16:16:56] <JT-Shop> btw, air filters are common on industrial equipment electrical cabinets
[16:17:04] <bill1123> i have a post processor error from rhinocam, "multiple Z words on one line" for this line: G87X0.Y0.Z0.8461Z0.1Z0.1F30.0
[16:17:22] <JT-Shop> well I do see Z twice
[16:17:43] <tjb1> The lazy ass who did the posts for rhinocam needs to add spaces
[16:17:50] <tjb1> So hard to read
[16:17:50] <bill1123> its for a breakchip drilling cycle
[16:18:00] <JT-Shop> are you using a DX32 post processor it looks like it
[16:18:01] <tjb1> Z is there 3 times
[16:18:15] <bill1123> its a modified bridgeport post processor
[16:18:33] <JT-Shop> which controller?
[16:18:38] <JT-Shop> they had many
[16:18:56] <JT-Shop> my BP 308 uses a similar code
[16:19:04] <tjb1> JT-Shop: I was planning on 1.5 or 1" slats
[16:19:32] <JT-Shop> also plan on it splashing out when your near open water :)
[16:19:32] <bill1123> not sure, I just am using the bridgeport example post from rhinocam
[16:19:40] <bill1123> and modified it for my generic CNC machine
[16:19:49] <JT-Shop> try a generic fanuc
[16:20:40] <bill1123> i see fanucs in there
[16:20:43] <bill1123> what are they?
[16:21:03] <bill1123> not sure why i picked bridgeport originally doh
[16:21:39] <tjb1> JT-Shop: You running water against the plate or an inch or so down?
[16:21:43] <JT-Shop> fanuc is a control like LinuxCNC and Anilam and Boss and a zillion others
[16:22:16] <bill1123> why pick fanuc though over all the rest
[16:22:20] <bill1123> there is a big list
[16:22:22] <JT-Shop> well in hind sight I would be able to run the water up to the plate, but I can only do that with my small pan insert
[16:22:48] <tjb1> Not a big enough resevoir huh
[16:22:50] <JT-Shop> try them all till one works
[16:22:59] <bill1123> sounds retarted
[16:23:03] <JT-Shop> no, it is under my slats :(
[16:23:17] <JT-Shop> poor design due to lack of experiance
[16:23:41] <JT-Shop> bill1123: do you see an EMC post processor?
[16:24:01] <bill1123> nope
[16:24:19] <JT-Shop> do you see one that says generic fanuc?
[16:25:27] <bill1123> there are about 7 with fanuc in the name
[16:25:32] <bill1123> i think for the number of axes
[16:25:39] <bill1123> ie Fanuc3
[16:26:06] <JT-Shop> a fanuc is usually the cloesest to LinuxCNC
[16:26:21] <JT-Shop> do you see RS274 by any chance
[16:26:22] <bill1123> ok I will run a post and see how it works
[16:26:55] <bill1123> nope
[16:27:04] <bill1123> there is mach2
[16:27:34] <JT-Shop> try that, mach is based on EMC
[16:28:03] <jp__> JT-Shop, How's things
[16:28:33] <bill1123> okok thanks
[16:28:49] <JT-Shop> not bad, just need to put a 3/4" x 2 1/4" hole in my electrical panel and the BP conversion is done
[16:29:03] <jp__> What happened with the MPG
[16:29:53] <JT-Shop> I needed to add ilowpass to smooth out the pulse stream to the drive...
[16:30:29] <JT-Shop> without if you have your servos tuned real well it tries to go to the commanded position at once
[16:31:32] <jp__> ah
[16:33:35] <sliptonic> pcw_home: Do you have a second to help me with correct wiring of 7i77 to sdf-1525-12 https://acrobat.com/app.html#d=x59x38dzNQftieH6cSt4Lw?
[16:34:27] <JT-Shop> need a password to view that page
[16:35:18] <sliptonic> Can you read the link from this page: http://www.practicalmachinist.com/vb/machinery-manuals-brochures/servo-dynamics-fenner-drives-sdf-1525-a-205632/
[16:35:27] <sliptonic> That's where I found it and I don't have a password.
[16:37:03] <sliptonic> If I read it correctly, TB5 pin 3 on 7i77 would go to J2 pin 1. TB5-4 to J2-2.
[16:37:51] <sliptonic> But I don't know what to do with enable.
[16:38:51] <pcw_home> bbiab

[16:53:58] <r00t4rd3d> i need to make a z like that but with the standard carriages
[16:55:05] <tjb1> I wanted to counterbore them but it only leaves ~.125 of meat under them
[16:55:10] <tjb1> They arent in the way so I left it
[16:55:25] <Jymmm> r00t4rd3d: You can be a PITA and a dick sometimes, but you did a very nice job on that box! (You might try a polarized filter on your camera to get rid of the washout)
[16:55:52] <tjb1> I had to do the chamfer with a countersink since our school cant buy chamfer mills
[16:55:58] <r00t4rd3d> thanks, i just used the point and shoot for the pics
[16:56:51] <Jymmm> r00t4rd3d: Ah, yeah, they suck for that. try reflected ight off or thru a white cloth or whitish/grayish cardboard
[16:56:56] <tjb1> If I have time this weekend after hunting, should get it all back together and at least get homing sequences done on X and Y
[16:57:43] <r00t4rd3d> my dslr has a polar filter and flash diffuser
[16:57:54] <Jymmm> ah, there ya go
[16:58:27] <r00t4rd3d> im not that good at taking pics with it yet though
[16:59:39] <Jymmm> bounce the flash off the ceiling sometimes help
[17:01:22] <tjb1> r00t4rd3d: I am going to draw up the router mounts tonight and maybe EDM them next week
[17:02:16] <Jymmm> r00t4rd3d: If you have plans you feel like sharing to build the box, let me know.

[17:05:35] <r00t4rd3d> radius is 1 3/8
[17:05:50] <tjb1> Eh…so is it 2.75?
[17:05:57] <Jymmm> Semi-gloss clear coat seems to look better and doens't attract/show as much dust.
[17:07:08] <tjb1> Are there any dust deflectors for ours?

[17:08:53] <tjb1> Its not even nice in metric
[17:09:14] <r00t4rd3d> use sketchup :D

[17:12:44] <r00t4rd3d> tjb1, he sent me the plans and stuff for it before but i lost them, i just asked for them again
[17:13:30] <Jymmm> andypugh: anything is better than 187
[17:16:07] <PCW> sliptonic:
[17:16:08] <PCW> 7i77 TB3.4 --> Drive pin 2 (+-10V signal)
[17:16:10] <PCW> and TB3.3 --> Drive pin 4 (analog input common)
[17:18:42] <tjb1> Actually r00t4rd3d im guessings its 69mm
[17:19:43] <r00t4rd3d> http://www.cnczone.com/forums/diy-cnc_router_table_machines/130046-dewalt_dwp611_1_25hp_router.html
[17:19:50] <r00t4rd3d> lots of info on it
[17:20:31] <PCW> Those drives have that funny "GND to disable" input so easiest is probably to do what
[17:20:32] <PCW> JT did and add relay with a NC contact than grounds all disables until a output bit (one of the 7I77s outputs)
[17:20:34] <PCW> is turned on by Linuxcnc
[17:20:53] <r00t4rd3d> tjb1, someone in that thread said it was 69mm also
[17:21:07] <sliptonic> PCW: Confirm 7i77 TB3? Encoder?
[17:21:23] <PCW> TB5 sorry
[17:21:51] <tjb1> My caliper isnt deep enough so I am not positive
[17:23:46] <tjb1> r00t4rd3d: What do you think, 1/2 or 3/4" thick clamps?
[17:23:50] <tjb1> Im planning on 2 of them
[17:24:06] <tjb1> Or maybe one like 4 inches long, that would be sexy
[17:24:42] <PCW> The other possibility with enable (drive pin 8) is to put a fairly stiff pulldown to ground (say 1K) and then use one of the enable OPTOs to pull it up to +15V
[17:25:07] <PCW> drive pin 8
[17:25:18] <sliptonic> PCW: Original wiring has J1-pin4 connected to the tach. J2-pin1 was connected to control.
[17:30:27] <sliptonic> I'm assuming differential input is preferable to single-ended input.
[17:31:54] <PCW> OK then it was jumpered for differential input so TB5.3 goes to J2 pin 2 and J1 pin4, TB5.4 goes to J2 pin1
[17:33:51] <Jymmm> r00t4rd3d: Here's a tip when V-Carving... to clean up the lil "nips" that remain after carving, use a green scotchbright to knock them down/off. Doesn't damage the wood either (as long as you're not too hard on it)
[17:34:09] <tjb1> r00t4rd3d: I was thinking of this.
[17:34:11] <tjb1> http://sphotos-b.xx.fbcdn.net/hphotos-ash4/408356_4358242750223_1642179325_n.jpg
[17:34:20] <Jymmm> r00t4rd3d: MUCH faster and easier than sanding or rotary tool
[17:35:16] <tjb1> What happens when you sandblast wood?
[17:35:25] <sliptonic> O.k. Thanks. JT-Shop: Any more details on your relay/disable solution?
[17:35:40] <PCW> So if 1K or so will disable drive that might be simpler than a relay
[17:40:28] <Jymmm> Has anyone come up with a nice, compact, portable wire spool stand/holder?
[17:40:50] <uw> just copy the harbor freight one
[17:40:55] <uw> and make it not suck
[17:41:14] <Jymmm> I said spools, not thimbles =)
[17:41:22] <Jymmm> 6-8"
[17:41:26] <Jymmm> diamter
[17:41:34] <uw> yup
[17:41:42] <uw> scale then?
[17:41:53] <PCW> so 1K (maybe lower) between J1 8 and 9 to disable and 7I77 ENA+ to J1 pin 10 and 7I77 ENA- to J1 pin 8
[17:41:54] <PCW> (make sure that D3 is not jumpered so J1.8 is an enable input only)
[17:42:11] <Jymmm> uwe_: nah, too much work
[17:42:11] <uw> its just 2 a-frames with bars connecting them
[17:42:26] <uw> i dont think think it's even cnc worthy
[17:42:39] <andypugh> Portable? http://cable-lashers.com/slabach_model_I85_reel_trailer.jpg
[17:42:43] <uw> crappyly cut rebar and 5mins of welding
[17:42:45] <Jymmm> it has to be "not get out my saw" worthy
[17:43:08] <uw> thats quite the spool
[17:43:14] <Jymmm> andypugh++
[17:43:28] <Jymmm> ok, add in carry by hand
[17:43:51] <uw> do i really have to photoshop that for you ;)
[17:44:36] <Jymmm> as long as I dont' have to pull out the saw
[17:45:31] <andypugh> Length of dowel hanging from two loops of wire fastened to the wall.
[17:45:31] <sliptonic> O.k. I think I understand that.

[17:48:26] <roycroft> hi folks
[17:48:48] <roycroft> some time ago someone here recommended an intel atom d525 system board as working well with linuxcnc
[17:48:56] <roycroft> i purchased one, and, indeed, it does work quite well
[17:49:11] <roycroft> the board has been discontinued, however, and i wonder if anyone has a recommendation for a replacement
[17:49:28] <roycroft> this is what i originally purchased:
[17:49:31] <roycroft> http://www.newegg.com/Product/Product.aspx?Item=N82E16813121442
[17:49:50] <roycroft> newegg list it as oos, however other vendors show it as discontinued
[17:51:25] <sliptonic> PCW: One more thing. Old wiring had limit switches wired into J1.6,7 Should I continue with that wiring in parallel to the 7i77 inputs?
[17:51:49] <andypugh> roycroft: I think PCW found one.
[17:52:15] <roycroft> one of the same board, or a suitable replacement?
[17:52:29] <andypugh> I am happy with the Intel DN2800, though it is PCIe and the graphics card has issues (OK at 1024x768 on the VGA, but not much else)
[17:53:04] <roycroft> my current project is a pbx, not a cnc controller
[17:53:26] <roycroft> however, the digium fxo/fsx boards have similar interrupt sensitivity
[17:53:44] <roycroft> so i thought a board similar to what i got for the cnc controller would likely do well
[17:54:03] <roycroft> and that intel was cheap, which i also like
[17:54:38] <roycroft> the dn2800 is a bit more, but still relatively inexpensive
[17:54:48] <roycroft> i don't care about graphics at all
[17:54:59] <andypugh> It runs from a 12V jack, which saves buying a PSU
[17:55:06] <roycroft> the thing will boot linux, and i'll occasionally need to go type at the console
[17:55:34] <roycroft> that's pretty cool, although i may need +5v for the digium board
[17:56:07] <PCW> sliptonic because those are active low they may or may not work with the 7I77 inputs (which expect active high inputs)
[17:56:23] <andypugh> http://www.amazon.com/Intel-Dual-Core-Mini-ITX-Motherboard-BOXD525MW/dp/B0041RSC94
[17:56:52] <roycroft> hmm, i didn't see that vendor before
[17:57:05] <andypugh> roycroft: You can pull 5V off of motherboard headers, or the SATA connector.
[17:57:09] <roycroft> i tried ordering from another amazon vendor who took the order and then informed me that they could not fulfill it
[17:57:28] <PCW> so if you have 24V control power, 7I77 inputs would be wired like +24 --> NC limit switch --> 7I77 input
[17:57:50] <roycroft> yeah, i could find 5v if necessary
[17:59:42] <roycroft> perhaps the thing to do is purchase some of the d525 boards while they can still be found, and then hope not to have a need for any more for a while
[18:00:09] <PCW> Theres alao this one:
[18:00:11] <PCW> http://www.newegg.com/Product/Product.aspx?Item=N82E16813128452
[18:00:37] <PCW> also
[18:01:03] <roycroft> thanks!
[18:01:08] <roycroft> that's more what i'm looking for
[18:01:13] <sliptonic> OK, cool. Thanks!
[18:02:47] <PCW> I think thats a pretty close clone of the Intel D525
[18:03:17] <jdh> there are/were a bunch on ebay

[19:32:12] <Valen> but with about 5x 6mm motors
[19:32:26] <Valen> the motors and sensors are basically sorted, but the motion controllers are the question
[19:32:42] <Valen> no paticular need for realtime, so USB would be fine
[19:32:48] <Valen> any suggestions?
[19:35:50] <djdelorie> how much power?
[19:35:58] <Valen> 6mm motors
[19:35:59] <L84Supper> Valen, what type of encoders?
[19:36:05] <Valen> smaller than your pinkie lol
[19:36:07] <djdelorie> volts? amps?
[19:36:10] <Valen> so ~1W
[19:36:19] <djdelorie> or is the whole motor 6mm and not just the shaft?
[19:36:24] <Valen> the whole motor
[19:36:29] <djdelorie> volts?
[19:36:35] <Valen> <5v
[19:37:00] <djdelorie> perhaps my board, without the high power driver: http://www.delorie.com/electronics/bldc/
[19:37:07] <Valen> L84Supper: some kind of optical encoder
[19:37:14] <djdelorie> if you decide to go custom :-)
[19:37:38] <Valen> does yours do servo motors or steppers only?
[19:37:53] <djdelorie> servos only
[19:37:59] <Valen> I'm looking for off the shelf for these ones
[19:38:05] <Valen> its just your page says bldc
[19:38:23] <djdelorie> DVD drives have tiny 12v motors, but I don't think their driver chips have encoder inputs
[19:38:34] <djdelorie> bldc = brushless DC
[19:38:51] <Valen> yes 3 phase things, my motors are brushed dc
[19:39:12] <djdelorie> hardware wise, same thing, just two wires instead of three :-)
[19:39:33] <Valen> doesn't feel quite off the shelf enough for me or my customers ;->
[19:39:41] <Valen> I'll keep it in mind for our new mill though
[19:39:59] <djdelorie> you probably only need the mcu in the middle anyway, not all the other stuff
[19:40:21] <Valen> nah it'll need a buffered drive, your not going to suck 1W from the mcu
[19:40:40] <PCW> what motor rating?
[19:40:49] <Valen> not decided yet
[19:41:04] <PCW> single or multi axis?
[19:41:17] <Valen> 7 axies potentially
[19:41:39] <PCW> what res encoders?
[19:42:00] <Valen> 16 ppr but probably have a ~1000:1 planatary gearhead on it
[19:42:58] <Valen> stall current is .2A
[19:43:40] <Valen> http://www.maxonmotor.com.au/medias/sys_master/8800945176606/12_050_EN.pdf are the motors i'm looking at at this stage
[19:43:46] <Valen> need to see if they have the herbs
[19:46:37] <ReadError> im scared to cut this CF
[19:46:43] <ReadError> after you all told me i would fail ;(
[19:46:59] <Valen> you can cut CF
[19:46:59] <ReadError> but i suppose i should, since its already paid for and such
[19:47:08] <ReadError> everyone was like "You need a waterjet"
[19:47:16] <ReadError> im like, *sigh*, me no has waterjet
[19:47:17] <Valen> pshaw, its soft
[19:47:29] <ReadError> i cut g10 fine
[19:47:34] <ReadError> awesome, infact
[19:47:37] <Valen> it'll dull the cutter pretty quick and you may get a furry edge
[19:47:42] <ReadError> figured it would be similar
[19:47:51] <ReadError> nothin a file cant knock down i suppose?
[19:47:54] <Valen> biggest concern is the fibers are really quite bad
[19:48:16] <Valen> nah, the problem (can be) you shatter the resin when you cut leaving the fibers floppy
[19:48:29] <Valen> try using a knife to clean up if you have an issue
[19:48:40] <ReadError> well it was only 57$ for a sq foot
[19:48:54] <ReadError> worse comes to worse i have an expensive mouse pad
[19:49:09] <Valen> robot people here cut it all the time with hacksaws and such like
[19:49:13] <Valen> just don't breathe the dust
[19:49:39] <ReadError> yea i stand there with a vacuum anyways
[19:49:49] <Valen> be double carefull of that
[19:49:57] <Valen> carbon is a conductor and light
[19:50:12] <Valen> if your vacuume is like normal ones the air goes through the motor
[19:50:23] <ReadError> nah its a shopvac
[19:50:25] <Valen> blowing carbon dust into a universal motor = big short circuit
[19:50:32] <ReadError> negative pressure -> filter -> out
[19:50:48] <ReadError> not a real shopvac
[19:50:48] <Valen> double check it, these days they just put a filter in the air stream they don't have a seperate fan for the motor
[19:50:50] <ReadError> but that style
[19:51:02] <ReadError> its HEPA also
[19:51:10] <ReadError> hopefully it can filter it
[19:51:30] <Valen> fingers crossed
[19:53:02] <L84Supper> Valen: not sure of the price http://www.qcontrol.com/PD/PR/QCI-S2-IG.html
[19:53:17] <L84Supper> for nema 11 servos
[19:54:11] <Valen> heh i think i would need to be sitting down for it somehow
[19:57:00] <r00t4rd3d> tjb1, https://anonfiles.com/file/6911db9f44e14f12d30a7a97890ac585
[19:57:08] <r00t4rd3d> dwp611 air deflector
[19:57:48] <tjb1> Thanks
[19:57:59] <tjb1> You using cncrp steppers?
[19:58:20] <r00t4rd3d> no, sparkfun.com
[19:59:40] <tjb1> Does Linuxcnc control your dwp?
[19:59:50] <r00t4rd3d> no
[20:00:03] <PCW> Valen: you could probably make 200 mA 5V Hbridges from ACT octal buffers
[20:01:31] <Valen> have to tie alot of pins together
[20:03:15] <tjb1> Thats just lazy r00t4rd3d :P
[20:06:41] <PCW> or a power opamp like on-semi TCA0372 (dual 1A less than $1.00)
[20:07:51] <Valen> I'll just use a h-bridge IC
[20:07:54] <Valen> i'm lazy ;->
[20:08:04] <Valen> I was actually thinking of using the mesa toolchain
[20:08:20] <Valen> price isn't quite no object but i do have a budget
[20:09:42] <PCW> a allegro a3968 would probably do
[20:10:05] <Valen> whats vin min?
[20:10:17] <Valen> (I'm just looking at the 7i30 now lol)
[20:10:28] <PCW> 4.5v I think
[20:10:43] <PCW> 7I30 is 12V minumum
[20:11:06] <PCW> (we have modified them before for tiny motors)
[20:11:15] <PCW> lowered current limit
[20:11:34] <Valen> I was thinking of just putting a 1W resistor in series for current limit
[20:11:48] <Valen> I can get those motors in 6v
[20:12:07] <PCW> SoftDMC firmware would work if you want coordinated motion
[20:12:13] <andypugh> I am fairly sure that a 6V motor will be happy on 12V if the current limit is correct.
[20:12:41] <PCW> (it up to 8 axis servo configs and USB interface is one of the options)
[20:12:51] <andypugh> And you _could_ trust a software PWM duty cycle limit
[20:12:54] <Valen> what interface, the whole thing is going into an underwater camera housing so i'm quite space constrained, I'm thinking of using a rasberry Pi for the controller
[20:13:21] <PCW> SoftDMC can use USB (or SPI if you like)
[20:13:23] <Valen> what board is it pcw?
[20:13:34] <PCW> 7I43 will do for 8 axis
[20:14:24] <Valen> interesting
[20:14:33] <PCW> bbl ttgh
[20:14:42] <Valen> thanks for the help pcw
[20:15:03] <Valen> if i go mesa I'll have to make sure you and IRC get credit lol
[20:31:19] <L84Supper> Valen, http://cubieboard.org/ might be a better fit than the Pi
[20:33:10] <L84Supper> ah sold out for now, nevermind
[20:35:59] <Valen> lvds is handy though
[20:36:21] <Valen> i might actually be able to drive a small screen for less than eleventy million $
[20:36:45] <Valen> and an adc
[20:36:47] <Valen> handy
[20:37:11] <Valen> what were they selling for L84Supper?
[20:38:16] <L84Supper> ~$50
[20:38:20] <Valen> nice
[20:38:34] <L84Supper> cubie works for allwinner the maker of the arm soc
[20:38:51] <Valen> at that price i can put a full stack debian in for about the same price as an AVR
[20:38:54] <L84Supper> he got flooded with orders
[20:39:28] <L84Supper> thats the plan, the A10 is in several low cost Chinese tablets
[20:39:53] <Valen> the I/O is whats missing from the rpi
[20:39:56] <L84Supper> http://www.engadget.com/2012/09/05/cubieboard-for-developers/
[20:40:23] <Valen> onboard storage is nice too
[20:40:33] <L84Supper> SATA !!
[20:40:45] <L84Supper> or microSD
[20:40:47] <Valen> that also adds a few options
[20:41:28] <L84Supper> I have a netbook with the A10
[20:41:30] <Valen> for the embedded stuff I want to do though 4GB of nand on board with no sd card hanging out over the side is good
[20:41:51] <Valen> if it did PoE and broke that out it'd be perfect lol
[20:55:15] <Valen> 1 Gb of ram is nice too lol
[20:55:27] <Valen> i'll have a friggin awesome light switch!
[20:55:52] <L84Supper> heh
[20:58:21] <Valen> my lights are going to be RGB LED strips so you know, there is *some* justification
[20:58:50] <L84Supper> what are you building?
[21:01:27] <Valen> renovating my house (thats what i want that cubie board for ;->)
[21:03:26] <Valen> I imagine i can get some pretty cheap lcd's for it too
[21:04:26] <L84Supper> HDMI :)
[21:04:38] <Valen> i want small ones, 5" or so
[21:04:51] <Valen> cant seem to find cheap hdmi screens in that size
[21:05:15] <Valen> but that thing has lvds and a few other lcd interfaces on it so i should be able to get bare LCDs
[21:05:37] <L84Supper> it also has a header for LVTTL LCD or RGB/LVDS, at least the SOC supports it, not sure of his pinouts
[21:06:05] <Valen> I figured I'd wind up making a PCB anyway to do POE and the like
[21:06:46] <Valen> I want to put automatic blind open close/angle and curtain closers as well, using the same board throughout the house has alot of appeal
[21:07:29] <tjb1> *a lot :P
[21:07:34] <tjb1> I had to :(
[21:07:43] <Valen> actually you didnt
[21:07:47] <Valen> <trollface>
[21:08:03] <tjb1> http://4.bp.blogspot.com/_D_Z-D2tzi14/S8TRIo4br3I/AAAAAAAACv4/Zh7_GcMlRKo/s400/ALOT.png
[21:08:08] <tjb1> :)
[21:20:01] <Valen> I have a VM on a spinning hdd, my main hdd is a ssd, I havent fired up the spinning hdd in months it sounds so weird to hear it grinding away booting the VM lol
