[02:09:41] <Deejay> moin
[02:16:09] <kengu> morning
[05:31:02] <jthornton> lumpy in here this morning
[07:26:02] <PetefromTn> Mornin' folks..
[07:27:41] <jthornton> morning Pete
[07:33:03] <PetefromTn> Hey JT!
[08:51:42] <nightshrill> miss anything?
[08:52:51] <archivist> yes, the end of the world
[08:55:02] <nightshrill> well we were all doomed anyway
[09:03:45] <JT-Shop> PetefromTn, did you get a chance to look at the sample G code
[10:07:26] <eric_unterhausen> there was an email on the list about touching off, I don't think it got any responses
[10:07:36] <eric_unterhausen> a little over a week ago
[10:08:49] <ssi> morn
[10:09:40] <PetefromTn> MOrn fellas.. and ladies if there are any here. LOL
[10:09:55] <eric_unterhausen> I tink is sausage-fest
[10:09:58] <PetefromTn> JT-Shop: Sorry I was out in the shop running some parts. Yeah I looked at it a little.
[10:10:58] <PetefromTn> gonna be trying to run it soon here I got some things I need to engrave but I will probably just make some kinda test run before I get too crazy with it.
[10:15:38] <zeeshan> ric_unterhausen> I tink is sausage-fest
[10:15:40] <zeeshan> lol
[10:15:58] <JT-Shop> PetefromTn, did it make sense?
[10:18:53] <PetefromTn> JT-Shop: Yeah it did kinda make sense but I have been busy with other things since we chatted and have not been able to get to it yet.
[10:20:20] <ssi> so I got that turrent punch lasterday
[10:20:25] <ssi> it's gonna be an interesting project
[10:20:33] <ssi> capacity is small though... 19x24" :/
[10:20:45] <ssi> but 1/8" mild steel punch capacity
[10:21:11] <ssi> no clue what I'm gonna do with it. That's too small to do airplane parts really
[10:21:19] <ssi> unless I can come up with sheet repositioning for it
[10:22:08] <zeeshan> whats the footprint of the machine|
[10:22:12] <zeeshan> er
[10:22:15] <zeeshan> 19x24, sorry missed it
[10:34:14] <zeeshan> PetefromTn: what kind of couplings did you use for the rf45 conversion
[10:34:57] <PetefromTn> I used some of those all metal laser cut split type couplings can't remember what they are called..
[10:35:10] <zeeshan> my stepper has a 1/2" shaft
[10:35:19] <zeeshan> but my ball screw has 20mm shaft
[10:35:22] <PetefromTn> Oh sorry the RF45 I used pullies machined to fit the ballscrew ends.
[10:35:22] <zeeshan> wtf!
[10:35:30] <zeeshan> ohh
[10:35:49] <PetefromTn> Then I pinned them thru with a heavy roll pin.
[10:36:05] <PetefromTn> and a setscrew opposite that.
[10:37:17] <zeeshan> i usually just used 2 set screws on the chain drives ive done in the past
[10:38:24] <zeeshan> i thought about what you said last night
[10:38:49] <zeeshan> i think a belt idea is a good idea in the sense you have have a "fusible" link"
[10:38:56] <zeeshan> if something crashes ;p
[10:42:26] <PetefromTn> zeeshan: Yeah man it is a real nice thing, when I was first setting up my RF45 servo system I had a runaway due to improper wiring and the axes reached the end of travel and the belt sheared saving me from much worse breakage I firmly believe. was NOT fun..
[10:43:19] <zeeshan> hehe
[10:46:09] <PetefromTn> Laugh it up fuzzball...
[10:46:24] <PetefromTn> ;)
[10:46:48] <PetefromTn> You guys want to see my finished custom scope sidehweel finally mounted?
[10:47:09] <zeeshan> yEs
[10:48:41] <PetefromTn> hang on a sec.
[10:52:21] <PetefromTn> http://imagebin.org/294655 http://imagebin.org/294656 http://imagebin.org/294657 http://imagebin.org/294658
[10:56:01] <PetefromTn> ssi: What are you gonna do with that punch?
[10:57:52] <JT-Shop> PetefromTn, is that an oversized knob to use with gloves?
[10:58:22] <JT-Shop> looks nice but you need to anodize it :)
[10:59:09] <PetefromTn> JT-Shop: Yeah it is that but actually what it is used for mostly is to rangefind the target. The large wheel allows you to put more accurate distance marks on the wheel giving better resolution so you can rangefind out to around 60 yards within a yard or two which is important for the competition...
[10:59:22] <CaptHindsight> PetefromTn: a pea shooter scope with vernier dial for the elderly?
[10:59:35] <PetefromTn> JT-Shop: Yeah I dunno about anodizing it, It is kinda blingy the way it is..
[10:59:50] <zeeshan> doing belt drive means an additional 150$
[10:59:51] <zeeshan> fak it
[10:59:52] <zeeshan> lol
[11:00:12] <zeeshan> pete
[11:00:14] <zeeshan> WTF is that!
[11:00:22] <PetefromTn> CaptHindsight: More like a $4k dollar scope for a top level competitor shooting a state of the art Field Target rig LOL....
[11:00:28] <zeeshan> why does the scope have such a bad ass wheel
[11:00:30] <zeeshan> next to it
[11:01:06] <PetefromTn> It is a scope accesory for Competition Target shooters..
[11:01:07] <zeeshan> <- doesnt know guns
[11:01:20] <zeeshan> i'm in canada
[11:01:22] <zeeshan> we don't have guns
[11:01:37] <CaptHindsight> so the shooter may be spotted more easily in the woods, otherwise it might be considered a terrorist tool
[11:01:41] <PetefromTn> Oh they shoot FT in Canada..
[11:01:53] <PetefromTn> LOL
[11:03:34] <CaptHindsight> anyone with a license to buy the rifle, you just need to wear this 5' diameter orange helmet whenever you use it
[11:39:36] * archivist hands zeeshan a gun to fire at the mericans across the border
[11:44:50] <IchGuckLive> hi all B)
[11:44:54] <Deejay> hi there
[11:48:15] <CaptHindsight> are they blocking the OUT DOOR yet?
[12:00:49] <CaptHindsight> ah so this is where those flimsy routers are coming from http://www.automationtechnologiesinc.com/products-page/cnc-router/cnc-mogul-machine
[12:01:13] <Cylly> ouch
[12:01:18] <CaptHindsight> cutting Area: 48" x 96" $1255
[12:01:27] <Cylly> ... that is no mill
[12:01:43] <Cylly> that is a joke
[12:05:46] <jmasseo_> looks pretty flimsy
[12:05:53] <jmasseo_> i guess you bolt it to your own table and hope for the best?
[12:08:41] <PetefromTn> Wow seriously a dremel felxshaft could twist that thing up...LOL
[12:12:30] <IchGuckLive> someone buys this joke is pretty confused
[12:12:43] <IchGuckLive> this will not mill foam in this standup
[12:14:12] <CaptHindsight> anyone try driving two steppers motors from one Keiling driver (obviously in parallel)?
[12:15:24] <archivist> barn door Repeatability: 0.005"
[12:16:59] <CaptHindsight> good for vinyl sign cutting
[12:17:26] <Connor> Yea.. looks like something for a vinyle knife..
[12:17:47] <CaptHindsight> paper origami
[12:17:55] <kengu> laser cutter
[12:18:07] <CaptHindsight> a light one
[12:18:08] <archivist> looks like something useful as an example of poor design
[12:18:12] <CaptHindsight> heh
[12:19:30] <archivist> no attempt to deal with any cutting forces
[12:20:14] <CaptHindsight> cream frosting router
[12:20:25] <CaptHindsight> custom butter art
[12:20:43] <archivist> good butter will bend that rubbish
[12:20:57] <CaptHindsight> warm butter
[12:21:18] <CaptHindsight> then again even as a liquid you couldn't move that thing quickly
[12:27:39] <archivist> even as a cnc paint stirrer I imaging the twisting force of the paddle will strain the gantry
[12:28:13] <CaptHindsight> unless you only have a z depth of a mm or two
[12:28:55] <CaptHindsight> vinyl cutter seems the best fit or light weight laser
[12:29:37] <CaptHindsight> piezo inkjet printheads even are ~1lb ea
[12:30:57] <CaptHindsight> http://www.automationtechnologiesinc.com/products-page/3d-printer-machine/3d-printer-mechanical-platform-no-controller
[12:31:45] <CaptHindsight> travel is only ~100mm
[12:32:47] <Connor> http://vimeo.com/58200103 pretty cool
[12:33:42] <kengu> http://www.instructables.com/id/DIY-CNC-Router/ or perhaps something like this http://grabcad.com/library/mini-plywood-hobby-cnc-router
[12:34:47] <archivist> why is that site in chinglish with an american address :)
[12:35:18] <CaptHindsight> archivist: automationtech?
[12:35:22] <Connor> archivist which site?
[12:35:43] <archivist> automationtech
[12:35:54] <Connor> Not sure.. it's in US though..
[12:36:01] <Connor> I've ordered from them before..
[12:36:21] <CaptHindsight> archivist: he's from China, but got his PhD in ME from the University of Illinois and lives here now
[12:36:47] <archivist> PHD ! how did he wangle that
[12:37:10] <Connor> http://grabcad.com/library/mini-plywood-hobby-cnc-router <-- Why do they always run the main gantry on the edge of the split linear bearing blocks.. much better to run them on top...
[12:37:32] <CaptHindsight> good student
[12:38:28] <CaptHindsight> he gives back to open source, he pays the ordbot guy and some other a few % for each unit he sells even though it's all open
[12:38:48] <Connor> Wish I had designed my Y axis so that the top rail was on TOP instead of both on their sides.. would have given a little better rigidity..
[12:40:04] <kengu> actually this is something interesting, http://grabcad.com/library/cnc-router-mill must be something wrong as there are not more of these
[12:41:24] <Connor> Also, the gantry is going to be way to heavy for the rails like they have it.. need to widen the base.. having it cantilever like that will cause too much friction on the rear bearing blocks.. I know.. I had issues with mine..
[12:41:50] <Connor> only thing that helped in mine was when I installed the ball screws.. they took a little pressure off it..
[12:41:57] <archivist> kengu, long unsupported bar rails are a mistake bar
[12:42:03] <IchGuckLive> Connor: on the edge is better tourch then on top
[12:42:19] <Connor> IchGuckLive: How do you figure ?
[12:43:04] <FinboySlick> Connor: Less split leverage I'd say.
[12:43:16] <CaptHindsight> if those bar rails were 40+mm in dia it would be ok, but thats expensive
[12:44:49] <archivist> CaptHindsight, I had a lathe with a bar bed, was terrible
[12:44:55] <archivist> 50mm
[12:45:18] <CaptHindsight> for a lathe
[12:45:43] <CaptHindsight> but a 12" router 50mm should be fine :)
[12:45:49] <FinboySlick> archivist: Full round slide or was there support like those split bearings?
[12:46:47] <CaptHindsight> I've used 8mm rails for travels under 2" and loads <0.5kg with success :)
[12:47:16] <archivist> FinboySlick, just end support like the crappy routers
[12:47:31] <CaptHindsight> flippy floppy
[12:47:33] <archivist> they resonate
[12:48:34] <archivist> just before it was trashed for parts http://www.collection.archivist.info/showresult.php?prog=1&srcprog=searchv13.php&srcdata=title&Type=PD&Accn_no=6966&subject=23753
[12:49:27] <FinboySlick> archivist: It's kind of cute despite being crappy.
[12:50:01] <CaptHindsight> Hobby says it all
[12:50:43] <archivist> the spindle is reasonable most of the problems are related to the bar bed
[12:54:11] <PetefromTn> Meh it's a POS.. LOL
[12:55:14] <PetefromTn> I need to build one out of 6061 plate or something so I can play with a router without firing up the monster outside.
[12:56:43] <PetefromTn> Who am I kidding, If i ever built one it would undoubtedly morph into a 50x100 monster before I was finished with it and it would need to be outside too LOL..
[12:58:32] <PetefromTn> My wife bought some fresh Cored pineapple from the store and I am eating it for lunch, it has got to be the sweetest juiciest most delicious Pineapple I have ever eaten anywhere Damn it is good.
[13:47:09] <zeeshan> archivist: lol
[14:17:53] <PetefromTn> What's so funny hehe
[15:00:38] <Einar_> When (in Axis) I try to open tool table it will open the window and allow editing. Some times nothing happens. Not even an error message. What do I do wrong?
[15:06:49] <PetefromTn> You are not doing anything wrong mine does the same thing and it is annoying...
[15:07:01] <PetefromTn> It is apparently a bug in the software or something.
[15:07:26] <cradek> in what version is this?
[15:07:49] <PetefromTn> I have been opening the tool table and edititing it in Gedit and saving it that way. Honestly it seems to actually work better as sometimes I found it did not save in the axis tool table editor.
[15:09:12] <PetefromTn> I am using the unstable version tho which may have something to do with it.
[15:17:17] <Deejay> gn8
[15:19:23] <CaptHindsight> just tried the latency test on a dual core APU ACER netbook ~70uS 10.04 with stock RTAI kernel
[15:19:46] <GammaX> Afternoon all
[15:20:04] <PetefromTn> Afternoon Gammax
[15:20:20] <GammaX> Boy its been a while since ive been in here!
[15:20:43] <GammaX> Movin from denver to ny in a few months so all my equipment is in a box truck :( no cnc for me.
[15:23:18] <Einar_> I'm using 2.6.0~pre. It seems I have to load the tool table editor before doing other things.
[15:24:32] <GammaX> im lookin for an accurate long lasting but best bang for the buck touch prove for digitizing and layout of material. any ideas?
[15:32:33] <PetefromTn> GammaX: That depends if it is for Hobby or Pro work I suppose.
[15:41:35] <GammaX> PetefromTn, I would say hobbiest pro work. pm45cnc machine but need semi close tollerances to produce work as side business.
[15:45:51] <MattyMatt> http://www.brusselsprout.org/cnc/1p-probe/
[15:49:28] <CaptHindsight> yeah, but copper oxidizes
[15:49:28] <CaptHindsight> who mints aluminum coins?
[15:49:39] <CaptHindsight> they also oxidize but the layer is only nanometers thin
[15:50:05] <CaptHindsight> looks like netsplit day
[15:50:09] <MattyMatt> eeh that's ugly on the photo
[15:50:09] <MattyMatt> one advantage to putting ball bearings on a pcb, like in other designs
[15:51:24] <CaptHindsight> i have to finish that camera touch probe
[15:51:39] <CaptHindsight> didn't someone finish that manual one?
[15:52:38] <PetefromTn> If you can find an older Renishaw probe via sniping ebay that would be your best bet. I hope to do the same here once I scrape up the coin. In the mean time I am working on a Tool length probe for the VMC...
[15:58:09] <CaptHindsight> http://dangerousprototypes.com/2013/05/14/diy-3d-laser-scanner/
[15:59:29] <CaptHindsight> http://www.metaingegneria.com/scanner-laser-3d/ make this work with EMC
[16:00:37] <CaptHindsight> http://www.instructables.com/id/3-D-Laser-Scanner/
[16:01:01] <CaptHindsight> I'm surprised nobody has done this yet
[16:34:27] <PetefromTn> Any of you guys use vibratory tumblers on your aluminum parts?
[17:55:47] * JT-Shop goes to stir the chili
[17:56:20] * Jymmmm sneaks in the tofu before JT-Shop strs the pot
[17:56:31] <uw> stepper powered stirer?
[17:56:37] <uw> or servo?
[17:56:47] <Jymmmm> hand powered
[17:57:02] <uw> booo
[17:58:11] <Jymmmm> better then FOOT powered
[18:04:51] <CaptHindsight> http://www.3ders.org/articles/20140220-openknit-printer-lets-you-pirnt-your-own-clothes-from-digital-files.html reminds me to write that PEARL script for EMC :)
[18:05:23] <Jymmmm> EMC is dead, LONG LIVE THE QUEEN!
[18:05:54] <CaptHindsight> Lcnc for us lazy people
[18:06:17] <CaptHindsight> should have been PURL script
[18:07:22] <CaptHindsight> http://openknit.org/
[18:09:08] <CaptHindsight> https://github.com/g3rard/OpenKnit/blob/master/assembly_manual.pdf?raw=true looks like more extrusion
[18:09:22] <CaptHindsight> only too light
[18:11:38] <CaptHindsight> clothing knitted onsite has potential
[18:13:23] <CaptHindsight> wovens and non-wovens can also be assembled by machine and either stitched, glued or welded
[18:25:05] <Tom_itx> PetefromTn, yes
[18:25:29] <PetefromTn> Tom_itx: Yes what?
[18:25:34] <Tom_itx> <PetefromTn> Any of you guys use vibratory tumblers on your aluminum parts?
[18:25:48] <PetefromTn> Oh really? Do tell..
[18:25:56] <Tom_itx> what's to tell?
[18:26:04] <Tom_itx> you need the right media
[18:26:18] <Tom_itx> depending what you're tumbling
[18:26:26] <PetefromTn> Tell me what you are doing and how and with what tumbler and with what medium and what kinda results are you acheiving>
[18:26:47] <Tom_itx> we had a little tabletop tumbler and one about the size of a tiny cement mixer
[18:27:31] <Tom_itx> depends on the parts but it doesn't take long depending on the result you want
[18:27:32] <PetefromTn> had or have?
[18:27:46] <Tom_itx> at my friend's shop
[18:27:53] <Tom_itx> we tumbled parts all the time
[18:28:12] <Tom_itx> not quite as rough as bead blasting but similar finish
[18:29:12] <PetefromTn> I have been wondering about doing some of that with these parts I am making. Only I need to deburr and then switch to something like walnut shells and rouge to polish them afterwasrds.
[18:29:46] <Tom_itx> http://clearwateren.com/gallery.php
[18:29:53] <Tom_itx> you can see the dull finish on some of those parts
[18:29:54] <PetefromTn> I am getting a nice finish on the parts but if I could cut the hand deburring time I could maybe make some more and faster...
[18:29:58] <Tom_itx> not all were tumbled
[18:30:27] <Tom_itx> you're not gonna have the bright machined finish when tumbled
[18:31:09] <PetefromTn> why have you only used abrasive media and not polishing media in them?
[18:31:14] <Tom_itx> you got a hand debur tool? those speed things up
[18:31:23] <PetefromTn> Of course I do..
[18:31:31] <Tom_itx> because that's what our vendors wanted
[18:31:38] <Tom_itx> no need to polish them
[18:31:52] <Tom_itx> most of the time they were painted anyway
[18:31:58] <PetefromTn> Agreed. But I need to be able to offer both a matte and a semi polished kind of finish.
[18:31:59] <Tom_itx> aircraft parts
[18:32:18] <Tom_itx> we used a DA sander too on some parts
[18:32:25] <PetefromTn> Yeah I have made several that were bead blasted then painted.
[18:32:31] <Tom_itx> all sorts of different debur stuff
[18:32:50] <PetefromTn> Yeah I got a nice D/A here and also a sweet little pneumatic hand belt sander I use a lot.
[18:33:46] <PetefromTn> along with a stand mounted belt sander and grinders and die grinders etc... I got all that but I was wondering about using a vibratory tumbler to try to cut some of the hand work out of the equation.
[18:34:32] <Tom_itx> works good but gives a flat finish
[18:34:44] <Tom_itx> maybe 30-60 min or so
[18:35:08] <Tom_itx> we just dropped the parts in and came back a bit later to rinse em off
[18:35:39] <CaptHindsight> that is quite a conundrum, remove large burs yet polish to a shine
[18:35:54] <Tom_itx> http://www.mscdirect.com/product/09117029?src=pla&008=-99&007=Search&pcrid=25122929464&006=25122929464&005=53303977984&004=7506848464&002=2167139&mkwid=snLzJwIUQ|dc&cid=PLA-Google-PLA+-+Test_snLzJwIUQ_PLA__25122929464_c_S&026=-99&025=c
[18:36:07] <PetefromTn> CaptHindsight: Who said anything about large burrs?
[18:36:08] <Tom_itx> yeah you wouldn't wanna tumble em if you were gonna polish them
[18:36:25] <Tom_itx> polishing would debur to an extent anyway
[18:36:38] <CaptHindsight> PetefromTn: well not measured in inches :)
[18:36:57] <Tom_itx> another place i was at had about an 18" buffing wheel on a bench grinder
[18:37:03] <Tom_itx> maybe 4" wide or so
[18:37:04] <PetefromTn> Honestly I did not have much in the way of burrs really for such a complex piece.
[18:37:42] <Tom_itx> don't tumble reamed holes etc
[18:37:48] <PetefromTn> The lathe turning made more burrs than the mill did and I used the hand deburring tool to remove that little bit.
[18:38:24] <PetefromTn> They are not actually polished really but a nice smooth finish with somewhat of a shine would be preferrable.
[18:38:59] <Tom_itx> you don't want a tumbler for that then
[18:39:00] <PetefromTn> I have looked at building a large vibratory tumbler and there is a guy locally selling a shop built one that looks to be decent altho the frame is rusted.
[18:39:06] <CaptHindsight> I need a small portable Linuxcnc controller for demos
[18:39:16] <CaptHindsight> the arm stuff isn't done yet
[18:39:25] <PetefromTn> arm stuff?
[18:39:38] <CaptHindsight> so a mini-itx case with a small LCD would work
[18:39:51] <CaptHindsight> ARM board with FPGA
[18:39:58] <CaptHindsight> arm stuff
[18:40:12] <PetefromTn> I had a sweet Mini ITX machine running my RF45 that was quite nice until it died on me.
[18:40:49] <CaptHindsight> has anyone tested a laptop with miniPCIe with Linuxcnc?
[18:46:44] <Tom_itx> http://www.kramerindustriesonline.com/tumbling-media.htm
[18:47:55] <Tom_itx> the media somewhat determines the finish
[18:56:07] <Tom_itx> CaptHindsight how far did andy get on his arm board kernel?
[18:56:41] <PetefromTn> Tom_itx: Yeah I may try to either get or build a tumbler and try it out.
[18:57:42] <Tom_itx> depending on the size of your parts a tabletop one would work fine
[18:59:03] <CaptHindsight> Tom_itx: not sure, two people are working on the cubie2 port now, preempt_RT is ~80uS currently
[19:02:50] <PetefromTn> Tom_itx: Yeah that is what I think a larger table top model should work for most of what I need to do here.
[19:04:52] <Tom_itx> square off some pieces and drill some holes in em and run a tumbler test before you commit to parts
[19:09:07] <ssi> CaptHindsight: I need to work on linuxcnc on arm as well
[19:09:13] <ssi> I've worked with BBB in the past, and I'm trying to spin up Udoo now
[19:10:00] <CaptHindsight> ssi: memleak is also porting RTAI to ARM
[19:10:13] <ssi> I thought there was a working xenomai for BBB already
[19:10:17] <CaptHindsight> we're using the allwinner A20
[19:10:23] <ssi> the cubie?
[19:10:46] <CaptHindsight> the BBB doesn't have a GPU that can support a local display so we can't use it :(
[19:10:56] <ssi> sure it does
[19:11:11] <CaptHindsight> the cubie2 can support HD video or gaming while running Linuxcnc
[19:11:34] <CaptHindsight> the BBB can run AXIS?
[19:11:40] <ssi> I dunno
[19:11:53] <CaptHindsight> maybe at .1 fps
[19:12:00] <ssi> I'm not so concerned with being able to display in 3
[19:12:01] <ssi> 3d
[19:12:46] <CaptHindsight> we passed on the BBB since it didn't pick a TI SOC with a decent enough GPU
[19:13:16] <ssi> cubie is 50% more expensive and seems to be unobtanium
[19:13:36] <CaptHindsight> the A20 is $6ea
[19:14:02] <ssi> are you going to build a board from scratch?
[19:14:13] <CaptHindsight> the cubie2 board is ~$60 but we can make a cubie2 + fpga for the same price
[19:14:30] <ssi> how far along are you on that
[19:14:31] <ssi> open project?
[19:14:34] <CaptHindsight> we are using a Mesa fpga for the cubie2 right now
[19:14:47] <ssi> over what bus?
[19:15:23] <CaptHindsight> SPI and some GPIO, Mesa made the board 6+ months ago, we're just finishing up the drivers
[19:15:51] <CaptHindsight> I can spin a custom board in a couple of weeks if i want
[19:15:54] <ssi> bleh when I asked pcw about doing this he said he thought spi was going to be too slow
[19:16:00] <ssi> sure, so can I :P
[19:16:10] <ssi> hell I can have it done by friday if the design is done :)
[19:16:10] <CaptHindsight> 100 mhz SPI
[19:16:17] <ssi> wait it's thursday now isn't it
[19:16:20] <ssi> make that tuesday :)
[19:16:31] <CaptHindsight> I mean I can design and make a board in a few weeks
[19:16:52] <ssi> is the mesa spi board generally available?
[19:17:15] <CaptHindsight> no drivers yet so they didn't release it IIRC
[19:18:29] <CaptHindsight> the next version allwinner soc has 6 or 8 cores, same footprint $6ea
[19:19:17] <ssi> what are you going to put on the fpga board? couple smartserial ports?
[19:20:06] <CaptHindsight> the mesa board has 3 anything IO 50 pin conn
[19:20:20] <CaptHindsight> plus the 50 GPIO lines from the A20
[19:20:30] <ssi> see I'd much rather see a 5i25 compatible board
[19:20:31] <CaptHindsight> lots of IO
[19:20:46] <CaptHindsight> it is
[19:20:57] <CaptHindsight> runs the same IP only over SPI
[19:21:13] <ssi> 5i25 doesn't use the 50 pin gpio ports
[19:21:20] <ssi> it uses the 25 pin dual sserial ports
[19:21:24] <CaptHindsight> I don't keep track
[19:21:36] <ssi> "superport" etc
[19:21:37] <CaptHindsight> what IO does it have?
[19:21:57] <CaptHindsight> it could be done
[19:22:05] <ssi> it should be very simple
[19:22:14] <micges-dev> ssi: you can use this: http://mesanet.com/graphics/parallel/hd-dbadptcolo.png
[19:22:29] <ssi> I looked into doing it last year, my only stumbling block was getting a spi host adapter 5i25 firmware built
[19:22:44] <ssi> then I was going to build a s6 lx50 fpga cape for bbb
[19:22:54] <ssi> I have some s3a200 bbb capes that I built
[19:23:31] <ssi> micges-dev: ah ok... you can use that to turn a regular 50 pin io port into a pair of superports?
[19:23:34] <ssi> or a single superport?
[19:23:35] <CaptHindsight> we can do everything on AMD apu boards now, using allwinner is really just for low cost appliance applications
[19:23:47] <micges-dev> ssi: single superport
[19:25:24] <ssi> CaptHindsight: via SPI on the apu?
[19:25:35] <CaptHindsight> PCIe
[19:25:39] <ssi> well sure
[19:25:42] <ssi> I can do everything with a Dell too :P
[19:26:00] <uw> that openknit iscool
[19:26:14] <ssi> I need to talk pcw into selling me one of the spi fpga cards
[19:26:24] <ssi> I'll help with the drivers if I can get my hands on one
[19:26:27] <micges-dev> CaptHindsight: will you share spi driver? I'm working now on mesa ethernet boards and after that I could add spi support to linuxcnc
[19:26:57] <CaptHindsight> micges-dev: yes, just like all the RTAI stuff
[19:27:18] <micges-dev> great
[19:27:20] <CaptHindsight> 2 full time devs are on the project now
[19:29:58] <CaptHindsight> the distros and tool chains for the allwinner were a mess so they just started from scratch
[19:32:31] <micges-dev> impressive
[19:33:19] <uw> lol allwiner
[19:33:43] <uw> i always loved that name
[19:33:56] <CaptHindsight> it used to be boxchip
[19:41:54] <CaptHindsight> i just don't like dealing with all the makerkrap
[19:46:48] <Connor_iPad> Yo
[19:54:09] <CaptHindsight> ssi: the comparison was between brand new hardware x86 and ARM that you could ship to customers under warranty. I wasn't comparing a 6 year old fleamarket PC controller to an new ARM system.
[19:54:54] <PetefromTn> Connor_iPad: YO yo..
[19:55:10] <CaptHindsight> I wish I could buy a brand new under warranty PC for $80 and put it into a new machine.
[19:55:14] <Connor_iPad> PetefromTn: How goes it.
[19:55:30] <PetefromTn> Its goin'...not entirely sure where LOL...
[19:56:07] <Connor_iPad> Rofl
[19:56:27] <PetefromTn> I posted the wheels on the forum I frequent for sale today finally and spoke with the forum owner over the phone he gave me permission to sell there for the time being for free until it starts to take off hopefully LOL...
[19:57:10] <PetefromTn> Right now I am trying to redesign a scope rail mount into something interesting enough that folks will reach for their paypal account number hehe
[19:57:16] <PetefromTn> What are you up to?
[19:57:30] <Connor_iPad> Oh cool. I thought you were making that for a existing customer.?
[19:58:12] <PetefromTn> I was this one is already sold and possibly the third one I made...
[19:58:24] <CaptHindsight> ssi: the imx6 has PCIe, but I'm not sure if any of the boards have a PCIe slot
[19:58:31] <Connor_iPad> I'm a bit depressed. Got a sinus headache. 3rd day in a row n
[19:58:32] <PetefromTn> Gonna be finishing it up tomorrow and shipping it out.
[20:00:15] <CaptHindsight> http://boundarydevices.com/products/sabre-lite-imx6-sbc/ has PCIe but at $199
[20:01:35] <CaptHindsight> http://www.wandboard.org/ huh they left PCIe off but starts at $79
[20:02:58] <CaptHindsight> another option might be ARM Gbit ethernet to MESA
[20:06:39] <PetefromTn> Connor_iPad: Man that sucks.... Nothing worse than a sinus headache sometimes it can really tear into ya.
[20:07:37] <Connor_iPad> Yea. What sucks is wife has no sympathy right now. She's in too much pain herself.
[20:07:50] <Valen> drugs are good mkay
[20:07:58] <Valen> also check out a "neti pot"
[20:08:11] <Valen> disgusting but helpfull or so the missus says
[20:09:49] <PetefromTn> mkay LOL..
[20:10:37] <PetefromTn> My wife helps me when I get a brain quake like this..
[20:10:57] <PetefromTn> She takes a blanket and folds in into a pad on the floor for me to lay on.
[20:11:48] <PetefromTn> Then she takes a small towel and wets it down and then rolls it into a cylinder shape and puts it in the microwave for maybe a minute or two.
[20:12:20] <PetefromTn> Then she takes the towel and rolls it up inside a bath towel so it is like a larger cylinder shape.
[20:12:43] <PetefromTn> Then I put it under the curve of my neck under my head like a pillow.
[20:13:07] <PetefromTn> Finally she takes another damp warm towel and puts it over my eyes and turns on some soothing music.
[20:13:27] <PetefromTn> This fixed my headache every single time and even helps when it is a sinus headache...
[20:13:38] <Connor_iPad> Cool
[20:15:55] <Valen> other thing i have done is a steambath for the head, add a bunch of herbs and such seems to clean the sinuses out
[20:17:28] <zeeshan|2> http://i.imgur.com/lQOwnem.png
[20:17:33] <zeeshan|2> do you guys think this is a bad idea
[20:17:41] <zeeshan|2> without using a line side filter
[20:18:02] <zeeshan|2> the power supplies are switched power supplies with voltage regulators
[20:32:24] <Connor_iPad> I would use a filter if possible.
[20:37:35] <Connor_iPad> So, what's everyone up to?
[20:40:22] <Connor_iPad> Guess no one is up to anything.
[20:40:47] <PetefromTn> I am trying to mod this scope rail design.
[20:51:17] <skunkworks> I am doing dishes and cleanup..
[20:51:49] <Jymmmm> skunkworks: you are SO domesticated =)
[20:54:10] <PetefromTn> WTF? Did I get bumped LOL?
[20:58:11] <PetefromTn> Connor: sorry man not sure what happened.
[20:58:33] <Connor_iPad> Guess so.
[20:59:11] <PetefromTn> What'd I miss
[20:59:39] <Tom_itx> tons
[20:59:49] <PetefromTn> I'm sure.
[20:59:55] <PetefromTn> ;)
[21:00:07] <eric_unterhausen> we were just talking about you
[21:00:09] <eric_unterhausen> no prob
[21:00:26] <PetefromTn> Connor: Did you work on the design at all?
[21:00:49] <PetefromTn> eric_unterhausen: Thanks buddy.. Ya know I love ya.
[21:01:17] <eric_unterhausen> hey, I was in a split by myself
[21:01:42] <eric_unterhausen> made me feel special
[21:02:21] <PetefromTn> so long as you are feeling special it's good by me man... Everyone needs to feel special once in awhile. Rolleyes.
[21:02:44] <eric_unterhausen> kinda pointless to be in a irc by yourself though
[21:02:56] <skunkworks> no it isn't
[21:02:59] <skunkworks> yes it is!
[21:03:00] <PetefromTn> depends on how entertaining you can be..
[21:03:25] <eric_unterhausen> not much usually, but I crack myself up
[21:03:55] <PetefromTn> what are you up to lately?
[21:04:20] <PetefromTn> We got some high winds outside right now and it is threatening to storm or something.
[21:04:51] <PetefromTn> I heard my big trash bin blow over but it is kinda empty so I don't feel like braving the storm for it just yet.
[21:05:07] <eric_unterhausen> is the lid attached? don't bother then
[21:05:16] <postaL> anyone here use CamBam?
[21:05:24] <os1r1s> PetefromTn: Think the same thing is here. The wind is pretty excessive
[21:05:27] <PetefromTn> It is one of those large ones with the flipper lid..
[21:05:34] <PetefromTn> postaL: I do..
[21:05:47] <postaL> Can I throw a couple questions (beyond this one) at you?
[21:06:02] <eric_unterhausen> u can try...
[21:06:06] <Tom_itx> may just throw them back
[21:06:07] <PetefromTn> I am not that knowledgeable about it just recently started using but but go ahead..
[21:06:14] <postaL> Tom_itx, lol
[21:06:27] <Tom_itx> i've used it 1.5 days... i'm a pro... ask away!
[21:06:35] <postaL> ok, so... first time using it, and i'm trying ot make a tool path to cut out a 2d drawing into G10
[21:06:36] <PetefromTn> ROFL..
[21:06:46] <postaL> selected the drawing
[21:06:48] <postaL> hit "PROFILE"
[21:06:52] <PetefromTn> Oh shit we are off to a bad start already..
[21:06:57] <postaL> and now i can give it options on how i want this thing to cut
[21:07:18] <postaL> under the general section ont he left, it asks if i want to cut inside or outside
[21:07:27] <PetefromTn> Oh you mean the material G10..
[21:07:30] <postaL> well, i have some holes in the middle, but for the outside edge i want it to cut on the outside
[21:07:36] <postaL> yes, g10 material
[21:07:48] <PetefromTn> Okay lemme stop you right there...
[21:08:13] <PetefromTn> You cannot select the entire drawing and then break it down by MOPs..
[21:08:27] <postaL> MOPs?
[21:08:28] <PetefromTn> You have to select the outside edge seperately and then create an MOP for that
[21:08:32] <postaL> http://snag.gy/tiKZL.jpg
[21:08:32] <PetefromTn> Machining operations..
[21:08:37] <postaL> ah, ok, gotcha
[21:08:55] <PetefromTn> Yeah that is a simple one.
[21:09:07] <PetefromTn> Are you gonna use tabs?
[21:09:22] <postaL> I would like to
[21:09:35] <postaL> tabs being, the little bit of material left over so the inside "object" stays in place, correct?
[21:10:19] <PetefromTn> You could either drill or mill the holes first and then follow it with bolting the parts down thru those holes or use tabs and yeah that is what a tab is..
[21:10:36] <postaL> and the tab thing is located under style
[21:10:55] <postaL> so, fo the outside cut, it would be "cutout + tabs"
[21:11:55] <PetefromTn> Tabs are under the heading holding tabs..
[21:12:37] <PetefromTn> You click on the little plus sign and it opens to show you the tab options automatic or manual etc..
[21:13:54] <postaL> i see
[21:14:01] <postaL> under the General section, for "style"
[21:14:06] <postaL> what would I put there?
[21:14:13] <postaL> just "cutout"?
[21:14:43] <Connor_iPad> Profile I believe.
[21:14:46] <PetefromTn> Honestly I have not put anything there so far but have not played with tabs much so I may be telling you wrong. I know you can select holding tabs without it so who knows.
[21:15:03] <PetefromTn> yeah under profile machine operation.
[21:15:19] <postaL> Connor_iPad, yeah, I clicked "Profile" to give me all these options
[21:15:39] <PetefromTn> Holding tabs is farther down the list. YOu did click advanced right...
[21:15:49] <postaL> Yeah, i see the holding tabs section
[21:16:19] <PetefromTn> os1r1s: You got the rough weather there too huh, where are you?
[21:16:29] <os1r1s> PetefromTn: memphis
[21:16:45] <PetefromTn> Wow that is pretty wide swath of shitty weather then huh LOL...
[21:17:18] <os1r1s> PetefromTn: The plus side is that all the piles of leaves everywhere are gone
[21:17:21] <PetefromTn> postaL: Remember you can make a rough and finish pass both using tabs if you need to...
[21:17:29] <Tom_itx> we had high wind warnings here today
[21:17:55] <PetefromTn> os1r1s: I just got tons of pine cones here in the yard from a Japanese Maple and the cones never blow away..
[21:19:43] <PetefromTn> I really need to get some cheap waterproof lights to put inside my VMC's enclosure. I managed to blow up the DC machinists lamp inside there and have not fixed it yet and the shop lights only do so much...
[21:21:27] <Tom_itx> led worklight
[21:22:02] <postaL> thanks for the help PetefromTn
[21:22:04] <os1r1s> PetefromTn: I was expecting my end mill holders today and USPS decided to take them on a journey. They are the last thing I need to start making molds.
[21:22:06] <postaL> gave me enough to get started
[21:22:12] <PetefromTn> This thing has a real nice DC worklight with articulating arm but when we wired up the machine thought the power was something else and fried hte bulb.
[21:22:21] <PetefromTn> postaL: No worries man good luck.
[21:22:44] <PetefromTn> os1r1s: Oh yeah what kinda endmill holders did you get?
[21:23:02] <os1r1s> PetefromTn: a2z ones
[21:23:12] <os1r1s> Just for a small mil
[21:23:13] <os1r1s> mill
[21:23:32] <PetefromTn> A2z..? Never heard of em. I'm sure they are nice tho.
[21:23:42] <PetefromTn> what kinda molds are you gonna make?
[21:24:26] <os1r1s> PetefromTn: I got a small injection molding machine. I need to make hundreds of some parts and any other method is a bit too painful.
[21:25:27] <PetefromTn> Cool.. I would love to get into some mold work with my machine. The guy I bought it from that is all he did with it. He said it was very good for that but the molds he was getting requests for were BIG so he needed a larger machine.
[21:25:49] <PetefromTn> He makes molds for Newell Rubbermaid and other places..
[21:25:57] <os1r1s> Very cool
[21:26:14] <os1r1s> Whats the max size on your mill?
[21:26:21] <PetefromTn> I saw several of them when I visited the shop to look at the machine and some were really big and heavy. Needed to be moved with a forklift.
[21:26:46] <PetefromTn> It is a 20x20x20 machining envelope. Inches.
[21:27:03] <os1r1s> PetefromTn: https://www.dropbox.com/s/55eie4v96d0i66c/IM150B.jpg
[21:27:32] <PetefromTn> Neato did you make that?
[21:27:48] <os1r1s> PetefromTn: No. It was a kickstarter
[21:28:03] <os1r1s> I thought about it, but it woo=uld have taken too much time.
[21:28:05] <os1r1s> would
[21:28:09] <PetefromTn> Really you did a kickstarter... Interesting..
[21:28:13] <os1r1s> I didn't
[21:28:23] <os1r1s> It started as one, then they started selling them
[21:28:36] <PetefromTn> okay.
[21:28:50] <os1r1s> PetefromTn: My first attempts ... https://www.dropbox.com/s/jdvrshuywphrgob/imlure.jpg
[21:28:53] <os1r1s> With a sample mold
[21:28:54] <PetefromTn> What kinda plastics can you use?
[21:29:10] <os1r1s> ABS, PP, PE
[21:29:18] <os1r1s> LPDE, HPDE
[21:29:21] <PetefromTn> So is that fishing lires?
[21:29:25] <os1r1s> They are
[21:29:35] <PetefromTn> Nice.
[21:29:42] <os1r1s> I don't have much interest in them, but it was what they gave to get me started
[21:30:02] <PetefromTn> whaddya mean they gave you?
[21:30:11] <os1r1s> It was included in the cost :P
[21:30:32] <os1r1s> They put one in the box so that you can test the machine in advance of making a mold
[21:30:40] <PetefromTn> So you had to make parts to get the machine...
[21:31:08] <os1r1s> No, it came pretty much ready to go
[21:31:40] <PetefromTn> What are ya gonna make with it?
[21:32:00] <os1r1s> I am making a CNC loom and I need to mold the heddle parts
[21:32:31] <PetefromTn> LOL NO idea..
[21:32:36] <os1r1s> hehe
[21:33:10] <os1r1s> PetefromTn: https://www.dropbox.com/s/4d9505skkzrwo5i/HeddleAssm0.1.JPG
[21:33:26] <os1r1s> The piece that goes up and down along with the brake
[21:33:37] <os1r1s> (The upside down L)
[21:34:01] <PetefromTn> Okay. did you draw that? what software?
[21:34:17] <os1r1s> PetefromTn: Solidworks
[21:34:37] <os1r1s> I have the entire machine modeled and functional. I've already 3d printed most of the brackets.
[21:34:38] <PetefromTn> Damn man am I the only loser here that cannot afford Solidworks LOL...
[21:34:45] <toastydeath> steal it obv
[21:35:03] <postaL> :x
[21:35:04] <eric_unterhausen> ya, they made it hard to buy
[21:35:06] <os1r1s> Now I just need to mill the carriages and make the mold.
[21:35:11] <postaL> tpb
[21:35:11] <postaL> :x
[21:35:28] <PetefromTn> tpb?
[21:35:37] <postaL> ThePirateBay
[21:35:40] <os1r1s> PetefromTn: I bought it because it saves me a ton of time.
[21:35:57] <PetefromTn> Oh I am sure I got to use it briefly, it kicks ass...
[21:36:05] <eric_unterhausen> yeah
[21:36:10] <PetefromTn> postaL: THX.
[21:36:17] <eric_unterhausen> cant figure out how to get my money back though
[21:36:25] <postaL> i don't condone piracy, but.. it's there for DL
[21:36:47] <PetefromTn> wait that is a real site LOL... I thought you were kidding hehehe
[21:37:01] <postaL> :))
[21:37:30] <os1r1s> PetefromTn: And stuff like this makes it worthwhile ... https://www.dropbox.com/s/bs0zuex8l79nz73/PapilioCase.PDF
[21:37:42] <PetefromTn> os1r1s: So you got a 3d printer, a mil, and an injection mold machine.. NICE.
[21:37:54] <os1r1s> PetefromTn: I have a lot more than that too :P
[21:37:59] <os1r1s> But all small size
[21:38:30] <PetefromTn> Looks nice but I don't know what the hell a Papilio is. Is that like an arduino or something.
[21:38:40] <os1r1s> Its an FPGA learning board
[21:38:49] <os1r1s> spartan6 just like a mesa boards
[21:38:53] <PetefromTn> Sweet..
[21:39:18] <os1r1s> PetefromTn: http://store.gadgetfactory.net/acrylic-case-by-os1r1s-papilio-pro/
[21:39:20] <PetefromTn> Mesa boards are the shiznit....jeez did I just say that.
[21:39:50] <zee-CNC> moment of truth
[21:39:51] <PetefromTn> Okay is that your product?
[21:39:53] <zee-CNC> about to test modbus
[21:39:56] <os1r1s> PetefromTn: The case is
[21:39:58] <PetefromTn> Oh hell..
[21:40:01] <zee-CNC> well wire it first
[21:40:18] <PetefromTn> zee-CNC: This on a VFD setup?
[21:40:39] <PetefromTn> os1r1s: Looks real nice man. That is injection molded too?
[21:40:51] <os1r1s> PetefromTn: No, that is done on my laser cutter
[21:41:07] <zee-CNC> PetefromTn, yes
[21:41:16] <PetefromTn> A laser cutter TOO?? Jeex man I need more CNC's here..
[21:41:16] <os1r1s> But I'm going to make a mold that I can IM for one of the smaller boards
[21:41:55] <PetefromTn> zee-CNC: We are gonna need docs and pics and some video here I am afraid.
[21:42:15] <PetefromTn> BRB guys gotta put the dog out..
[21:46:16] <PetefromTn> Damn it is spooky windy outside tonight.
[21:46:41] <PetefromTn> os1r1s: So did you make the laser cutter too?
[21:46:58] <os1r1s> PetefromTn: No. Bought it off of fleabay
[21:47:07] <os1r1s> The only machines I really build are 3d printers
[21:47:28] <os1r1s> The rest I just use :)
[21:47:38] <PetefromTn> I try to come up with interesting stuff to make and sell but it is hard when you are a dimwit. Looks like you got some good ideas.
[21:47:53] <os1r1s> I've got a ton more. Just no time
[21:48:16] <os1r1s> Life is cruel that way. Time with no money. Money with no time.
[21:48:40] <PetefromTn> I am trying to come up with cool ideas that I can make and machine with the VMC here to sell along with trying to find paying work for it.
[21:48:59] <os1r1s> You can make me some alu plates for one of my printers ;)
[21:49:17] <PetefromTn> Just spoke to a friend on facebook tonight who is in Ohio and he saw something I posted that I machined.
[21:49:46] <PetefromTn> Apparently he owns and runs a race shop and is always needing parts machined custom so maybe he can get some parts work for me.
[21:50:07] <os1r1s> Thats cool
[21:50:25] <os1r1s> If I had a big vmc I'd be soliciting that left/right
[21:50:32] <PetefromTn> os1r1s: Hey man I am game if I can make some decent cash with it LOL... the machine works good and cuts sweet. Did you see my custom wheel I made...
[21:50:44] <os1r1s> I did not see the custom wheel
[21:51:06] <PetefromTn> hang on...Gratuitous pic posting is my specialty..
[21:51:33] <PetefromTn> http://imagebin.org/294739
[21:52:08] <PetefromTn> http://imagebin.org/294740
[21:52:29] <os1r1s> PetefromTn: The white panels on this printer I want done in 6061
[21:52:30] <os1r1s> http://www.youtube.com/watch?v=PRBrvC7B9Wk
[21:53:06] <os1r1s> PetefromTn: Very nice
[21:53:14] <Connor_iPad> What sort of hot end is that?
[21:53:24] <os1r1s> Connor_iPad: That is a j-head
[21:53:33] <PetefromTn> yeah that thing kicks ass... I thought they were much slower than that..
[21:53:38] <os1r1s> haha
[21:53:57] <PetefromTn> How big is the panels?
[21:54:22] <PetefromTn> I would love to have one of those GGG's... Looks like fun.
[21:54:43] <os1r1s> 8x12 I think
[21:54:49] <os1r1s> Could be 12x16
[21:54:54] <os1r1s> Pretty simple though
[21:55:28] <os1r1s> PetefromTn: GGG?
[21:55:38] <PetefromTn> Glorified Glue Gun...
[21:55:55] <os1r1s> PetefromTn: This is 2 years ago ... http://www.youtube.com/watch?v=8GU6SxTzSr4
[21:56:25] <os1r1s> PetefromTn: Now I do stuff like this ... http://mounicou.com/share/kvasea.jpg
[21:56:58] <PetefromTn> Jeez what the hell is that a vase?
[21:57:04] <os1r1s> PetefromTn: Yes
[21:57:10] <PetefromTn> Sweet.
[21:57:33] <Connor_iPad> I want a new 3d printer. The cupcake sucks
[21:57:36] <os1r1s> PetefromTn: http://mounicou.com/share/excavator.jpg
[21:57:42] <os1r1s> That I did for my 4 year old
[21:58:26] <PetefromTn> Thats neat. How much does it cost to make something like that in materials?
[21:58:34] <os1r1s> .75
[21:58:38] <os1r1s> Maybe .50
[21:58:49] <PetefromTn> Wow.. Looks like fun.
[21:59:02] <PetefromTn> How big is that exactly?
[21:59:16] <os1r1s> PetefromTn: I put on a festival in March revolving around 3d printers. Its great fun if you can get to Goshen
[21:59:20] <zee-CNC> hey guys
[21:59:26] <zee-CNC> how can i manually trigger an output
[21:59:46] <zee-CNC> in test hal command?;p
[21:59:54] <os1r1s> PetefromTn: The excavator is about 7 inches long, 3" wide, and about 4 high
[22:00:14] <PetefromTn> Goshen Tn?
[22:00:35] <skunkworks> zee-CNC: setp 'pin-name' true
[22:00:56] <zee-CNC> does e-stop need to be off
[22:01:29] <skunkworks> no
[22:02:07] <skunkworks> (well - unless you have some hardware that requires some sort of charge pump/watchdog to enable the outputs
[22:02:07] <os1r1s> PetefromTn: Goshen, IN
[22:02:10] <zee-CNC> just to clarify
[22:02:19] <PetefromTn> OK
[22:02:27] <zee-CNC> man how do you copy from the show dialog
[22:02:41] <skunkworks> ctrl - c
[22:02:44] <skunkworks> maybe
[22:02:46] <zee-CNC> doesnt work
[22:03:14] <zee-CNC> component pin mvx9000rtu.commfrequency = value 0x00000012
[22:03:52] <zee-CNC> so all i gotta do is "setp mvx9000rtu.commfrequency 0x00000020"
[22:03:55] <zee-CNC> to change its value?
[22:04:02] <skunkworks> sounds right...
[22:05:42] <PetefromTn> Connor: What's a cupcake?
[22:06:14] <Connor_iPad> Type of opensource 3d printer.
[22:06:25] <Connor_iPad> Rather old design now.
[22:06:28] <os1r1s> PetefromTn: One of these ... http://mounicou.com/makerbot/CloakedMakerbot.jpg
[22:06:31] <Connor_iPad> Outdated.
[22:07:05] <PetefromTn> okay. You made one of those, how does it work other than sucks..
[22:07:20] <PetefromTn> Looks kinda small.
[22:08:06] <Connor_iPad> Yea. One 100mm x 100mm X by Y
[22:09:59] <Connor_iPad> Build area. That is. Don't recall the Z
[22:10:48] <os1r1s> Connor_iPad: 100
[22:11:20] <Connor_iPad> I thought it could go taller than 100mm ?
[22:11:31] <os1r1s> Not that I remember
[22:11:35] <os1r1s> But it was long ago
[22:13:26] <Connor_iPad> 130mm
[22:15:16] <PetefromTn> That is not too bad really.
[22:16:07] <Connor_iPad> That's small. I want one that can do much bigger.
[22:16:23] <os1r1s> My current one can do 300x290x220
[22:16:30] <os1r1s> So much larger than the old ones
[22:16:36] <PetefromTn> Well I want one too but how much does it cost to make one say twice that size?
[22:16:52] <os1r1s> And my rostock can do 290 (diameter) by 354 height
[22:17:22] <os1r1s> PetefromTn: It gets much harder to use them above that size
[22:17:26] <Connor_iPad> What can a Prusa do?
[22:17:33] <os1r1s> Connor_iPad: an I3?
[22:17:47] <os1r1s> 200x200x200 or so
[22:17:50] <PetefromTn> Who comes up with these names man?
[22:17:52] <zee-CNC> damn it
[22:17:54] <zee-CNC> vfd not working
[22:18:08] <PetefromTn> jeez man with Modbus or wiring?
[22:18:14] <zee-CNC> i think its the programming side
[22:18:15] <zee-CNC> cause
[22:18:19] <zee-CNC> i can see values for inputs
[22:18:25] <zee-CNC> so i think its communicating
[22:18:26] <Connor_iPad> Not sue. Original I guess.
[22:18:39] <os1r1s> Connor_iPad: Original is 200x200x130 or so
[22:19:21] <PetefromTn> So I guess timing is important on them or the thing will turn into a big gooey mess right I dunno jack about 3d printing.
[22:19:40] <zee-CNC> its telling me the drive temp is 21.1 c
[22:19:44] <zee-CNC> seems pretty reasonable
[22:19:47] <zee-CNC> lemme check dc bus voltage
[22:19:53] <os1r1s> PetefromTn: Timing is very key
[22:20:02] <zee-CNC> 342.5vdc
[22:20:02] <zee-CNC> wtf
[22:20:18] <PetefromTn> JEEZ..
[22:20:26] <zee-CNC> somethings gotta be off
[22:20:46] <PetefromTn> Ya Blowin' it man....
[22:20:50] <zee-CNC> hehe
[22:20:58] <zee-CNC> imgonna put it in manual mode
[22:21:02] <zee-CNC> and monitor the frequency i command
[22:21:22] <PetefromTn> what VFD is this again?
[22:22:53] <PetefromTn> Just got a flyer email from Horrible Freight for 20% off. I might have to look at one of their 18 lb vibratory tumblers and see what it would run after discount.
[22:24:00] <PetefromTn> Still be about $150 bucks..
[22:24:11] <os1r1s> PetefromTn: I have 2 of their smaller ones that I like
[22:24:24] <PetefromTn> Oh yeah have you done aluminum in them?
[22:24:27] <os1r1s> Yeah
[22:24:43] <PetefromTn> can you get a somewhat polished finish on CNC milled parts with it?
[22:25:17] <PetefromTn> Was thinking of getting that bigger one and trying a wheel in it.
[22:25:25] <zee-CNC> eaton mvx9000
[22:25:29] <os1r1s> a wheel?
[22:25:35] <os1r1s> Oh, the one you put up
[22:25:40] <PetefromTn> yeah that kinda wheel I posted earlier.
[22:25:50] <PetefromTn> and other small stuff.
[22:25:55] <zee-CNC> pete!
[22:25:55] <os1r1s> That would be pretty pricey
[22:25:58] <zee-CNC> its montioring right!!!
[22:26:05] <zee-CNC> im running it at 14.7 hz
[22:26:05] <PetefromTn> why>
[22:26:15] <zee-CNC> and i can see 14.7 hz in hal.
[22:26:22] <zee-CNC> (its in hexadecimal)
[22:26:24] <PetefromTn> zee-CNC: SWEET.
[22:26:40] <os1r1s> PetefromTn: Check the pic ... http://os1r1s.com/?p=988
[22:27:01] <os1r1s> PetefromTn: That was my first test. I can do better now ;)
[22:27:58] <os1r1s> PetefromTn: Its more complicated than I first thought
[22:27:59] <PetefromTn> That does not look too bad. That is the small model 5lbs?
[22:28:11] <PetefromTn> Isn't everything...
[22:28:23] <os1r1s> It really takes 3 stages of diff materials
[22:28:49] <PetefromTn> That is what I am understanding. Finishing with Walnut shells or corn cobs and rouge..
[22:29:42] <PetefromTn> Is it loud as hell in person?
[22:29:57] <os1r1s> PetefromTn: The 5 lb version
[22:30:05] <os1r1s> PetefromTn: No, its actually pretty quiet
[22:30:42] <PetefromTn> Have you tried to attain a polished finish on them?
[22:31:09] <os1r1s> That is my next step, but I got distracted
[22:31:34] <os1r1s> I use the ceramic adhesive, then resin, then walnut shells with rouge
[22:31:45] <os1r1s> The pics you see were just 1 of those steps
[22:31:59] <PetefromTn> ceramic adhesive?
[22:32:36] <PetefromTn> How much does it cost to buy materials enough to fill it up?
[22:32:54] <zee-CNC> the problem is..
[22:32:55] <zee-CNC> its readig
[22:32:57] <zee-CNC> *reading
[22:32:59] <zee-CNC> but not writing.
[22:34:09] <PetefromTn> So you can't control it so far I guess.
[22:34:14] <zee-CNC> yes
[22:34:21] <zee-CNC> im gonna go through the code
[22:34:33] <zee-CNC> and see if i can at least be able to send it a command frequency
[22:34:41] <os1r1s> PetefromTn: Its about $60 for the materials for a 5 lb tumbler
[22:34:42] <zee-CNC> cause that way i can see it pop up on the vfd lcd
[22:34:50] <Connor_iPad> Do you have the correct agree
[22:34:58] <Connor_iPad> Address I'd for the VFD?
[22:35:08] <Connor_iPad> Address ID.
[22:35:52] <PetefromTn> Gonna switch to my phone and head upstairs fellas I want to hear about this. BRB...
[22:35:58] <Connor_iPad> os1r1s: Any of your printers do dual head?
[22:36:52] <os1r1s> Connor_iPad: Yes http://os1r1s.com/?p=822
[22:37:35] <Connor_iPad> It work good?
[22:38:08] <os1r1s> Connor_iPad: Its not really worth it
[22:38:17] <Connor_iPad> Why not?
[22:38:34] <ssi> I wonder if color mixing heads have come any further
[22:43:11] <PetefromTn> Ola'
[22:45:04] <Connor_iPad> os1r1s: Support material used these days?
[22:45:26] <zeeshan|2> pete what vfd are you running on your vmc
[22:45:38] <toastydeath> i'm still shocked that printers don't use a 5 axis setup and do away with support material
[22:45:53] <os1r1s> Connor_iPad: I use just normal PLA and break it away
[22:46:34] <Connor_iPad> Why dual head not worth it ?
[22:46:50] <PetefromTn> Mine is a Hitachi WJ 200-110
[22:48:22] <os1r1s> Connor_iPad: A bitch to calibrate, and support materials are limited
[22:48:52] <Connor_iPad> What's your thought on Delta based printers?
[22:49:32] <Connor_iPad> And what's all the rage with them?
[22:50:00] <os1r1s> Connor_iPad: My rostock ... http://mounicou.com/share/rstkrkt.jpg
[22:50:05] <os1r1s> Tuning ...
[22:50:30] <Connor_iPad> Tuning?
[22:50:33] <os1r1s> Connor_iPad: Faster, cooler, better quality
[22:50:39] <os1r1s> That pic was while I was tuning
[22:51:33] <Connor_iPad> How can they be faster? And better quality?
[22:51:59] <os1r1s> Connor_iPad: Direct motion, less jitter
[22:52:04] <PetefromTn> Is that the one where the head stays perfectly flat to the bed or can you five axis it. ?
[22:52:54] <os1r1s> PetefromTn: http://www.youtube.com/watch?v=cTgQ8jODdlg
[22:52:58] <Connor_iPad> Bowden cables design?
[22:53:28] <os1r1s> Connor_iPad: It is bowden
[22:54:00] <Connor_iPad> I want to build a new one at some point...
[22:54:46] <Connor_iPad> I have one of the original maker gear extrudes.
[22:54:55] <Connor_iPad> One with gearbox.
[22:55:00] <os1r1s> Connor_iPad: Those are good
[22:55:07] <os1r1s> Very good
[22:55:51] <Connor_iPad> And a big head hot end to use on a wades extruded. Had issues with the hobbed bolt on that one.
[22:56:33] <PetefromTn> Man the wind is making my whole house creek...jeez.
[22:57:02] <Jymmmm> Stop eating beans for dinner then.
[22:57:04] <Connor_iPad> The big head doesn't have the ptfe for use with PLA
[22:57:23] <PetefromTn> ;)
[22:57:55] <PetefromTn> How'd you know I had beans for dinner?
[22:58:34] <os1r1s> Connor_iPad: You have one of the really old ones :)
[22:58:35] <Jymmmm> PetefromTn: 2014-02-20.20:39:49 PetefromTn: Man the wind is making my whole house creek...jeez.
[22:58:49] <roycroft> hey, folks
[22:58:53] <PetefromTn> My wife made that delicious black bean soup again. Damn it was good but I pity the fool who lofts the blankets LOL...
[22:59:02] <Connor_iPad> os1r1s: Yea. He gave it to my while I waited on the gearbox ones.
[22:59:05] <roycroft> this isn't cnc-related, but i know many of you folks know about such things
[22:59:26] <roycroft> i need a 2 pole, 50a 250v contactor that can be activated with a momentary contact switch
[22:59:41] <roycroft> such that if there's a power failure it won't engage when power is restored
[22:59:59] <roycroft> i can't find such a thing - is there a fancy name for it that i don't know?
[23:00:19] <roycroft> i'd prefer to activate it with 120v
[23:00:24] <roycroft> ac power, btw
[23:00:28] <PetefromTn> My system is setup that way but I repurposed the original contractors in the machine.
[23:00:56] <roycroft> yeah, i can buy "safety switches" that do that
[23:01:06] <Connor_iPad> roycroft: Relay for a AC unit.
[23:01:07] <roycroft> but i need a stand-alone contactor
[23:01:17] <roycroft> and the "safety switches" are mechanically activated
[23:01:34] <roycroft> i.e. you push a button
[23:02:06] <roycroft> i'll look on some hvac sites
[23:02:24] <PetefromTn> Mine does not use safety switches just a large contractors and a special circuit that has a lower voltage trigger that locks it down.
[23:02:57] <roycroft> i know exactly what i want to do
[23:03:04] <roycroft> and i know it's not a unique application
[23:03:11] <roycroft> but i'm having a really hard time finding what i need for it
[23:03:15] <PetefromTn> Okay.
[23:03:26] <Connor_iPad> What are you trying to do?
[23:03:38] <roycroft> i'm building a new brew system (for making beer)
[23:03:51] <roycroft> i'm bringing 50a into the control panel
[23:04:03] <roycroft> i want to activate it with a momentary contact key switch
[23:04:11] <roycroft> so that if the power goes out it won't go back on automatically
[23:04:20] <roycroft> and i want the key switch so people can't mess with it
[23:04:25] <roycroft> easily
[23:05:07] <roycroft> i suppose i could put a key switch in front of a push button contactor, but that's inelegant at best
[23:05:38] <Connor_iPad> Key switch in series with push button.
[23:05:43] <roycroft> yes
[23:05:50] <roycroft> that's what i want to avoid if possible
[23:06:33] <Connor_iPad> To toggle a DPDT relay rigged to latch. And provide power to coils on big contactor b
[23:06:35] <roycroft> i'd rather have a momentary contact key switch engage a coil in the contactor that will remain energized until power is killed
[23:07:05] <roycroft> i'll have a big estop switch on the thing
[23:07:28] <Connor_iPad> The key in series to provide security.
[23:07:41] <roycroft> i'm mixing high voltage and high current with a sloppy, wet environment
[23:07:48] <roycroft> so i'm being very cautious in the design
[23:07:59] <roycroft> and yes, i'm installing a gfci breaker in front of all of it
[23:08:37] <roycroft> i don't plan on getting the control panel wet, and i'll make it as water resistant as possible
[23:08:39] <PetefromTn> Well folks I'm fallinw
[23:08:40] <roycroft> but stuff happens
[23:08:52] <PetefromTn> Asleep talk tomorrow.
[23:08:53] <roycroft> i may have to do the push button + keyswitch
[23:09:21] <roycroft> there are lot of hvac contactor options, though, many of which i've not seen in other contexts
[23:09:23] <Connor_iPad> I'm not following why you MAY have to?
[23:09:25] <roycroft> so i might find something yet
[23:09:42] <roycroft> because i can't find a contactor that works with the momentary contact switch
[23:10:13] <roycroft> i'm still looking, though
[23:10:36] <Connor_iPad> Use a secondary DPDT relay in latching for that.
[23:11:23] <roycroft> perhaps i'm being dense, but i'm not seeing how that is going to work
[23:11:46] <roycroft> i remove control power from the dpdt relay and the power out shuts off
[23:11:53] <roycroft> removing power to the main contactor control
[23:11:55] <Connor_iPad> Push button toggles the latch relay. It in turns provides power to coils on main contactor.
[23:12:20] <Connor_iPad> No. DPDT in LATCH config.
[23:12:42] <Connor_iPad> After it engages. It provides power to itself via the contacts.
[23:12:55] <roycroft> aah
[23:13:01] <roycroft> ok, that's the bit i was missing
[23:13:06] <roycroft> a latching relay
[23:13:12] <roycroft> that's the term i needed
[23:13:16] <roycroft> and yes, that's perfect
[23:13:23] <roycroft> better than i expected, even
[23:13:35] <roycroft> because i see some pulse-activated ones
[23:13:52] <roycroft> the momentary contact key switch can pulse it on and pulse it off
[23:13:54] <roycroft> thank you
[23:13:56] <roycroft> that is perfect
[23:14:20] <roycroft> i knew someone here would know :)
[23:15:24] <roycroft> and they are cheap
[23:16:11] <Connor_iPad> Cool. Dunno anything about pulse activated ones. But a standard relay on latching setup is pretty common
[23:16:17] <roycroft> teh google is being very helpful now that i'm asking about "latching relay"
[23:16:32] <roycroft> one of the first hits i found was for a pulsing one
[23:17:05] <roycroft> http://www.automationdirect.com/static/specs/755relays.pdf
[23:17:27] <roycroft> it looks like it requires two different pulses, though - not pulsing the same contact twice
[23:17:35] <roycroft> i could still make that work
[23:17:50] <zee-CNC> ls
[23:18:01] <roycroft> rm -fr .
[23:18:06] <zee-CNC> acident
[23:19:30] <Connor_iPad> And like you wanted. Secure by putting rotary key switch I. Series with the start latch push button
[23:19:53] <Connor_iPad> Basicly disables the push button.
[23:20:37] <Connor_iPad> No key, no start. The off or reset button still will work. Which is a NC switch. Wire estop NC in series with it as well.
[23:20:49] <roycroft> yup
[23:21:16] <Connor_iPad> Standard industrial on off setup.
[23:21:41] <roycroft> i'm overdesigning this thing
[23:21:48] <roycroft> but it's my ultimate brew system
[23:21:53] <zee-CNC> WOOOHOO
[23:21:57] <zee-CNC> im writing the frequency to the VFD
[23:21:58] <zee-CNC> it WORKS
[23:22:02] <roycroft> the controller cabinet will be honduras mahogany
[23:22:08] <roycroft> the panel itself will be solid brass
[23:22:09] <Connor_iPad> zee-CNC: What was the issue?
[23:22:15] <zee-CNC> code was buggy
[23:22:19] <roycroft> the temperature and timer displays will be nixie tubes
[23:22:35] <roycroft> and all the indicator lamps will be neon
[23:22:39] <roycroft> as much nos as possible
[23:23:08] <zee-CNC> man i love the fact the vfd has built in safe features
[23:23:18] <zee-CNC> like i tried to command 70hz when the max hz is set to 60hz
[23:23:22] <zee-CNC> and it won't let me set 70
[23:24:07] <zee-CNC> now to fix the other write registers
[23:24:08] <Connor_iPad> zee-CNC: So you going to send me a VFD to play with? :)
[23:24:13] <zee-CNC> haha
[23:24:36] <zee-CNC> get one off ebay! they're cheap~!
[23:26:25] <zee-CNC> just get any eaton drive
[23:26:31] <zee-CNC> this driver should work withit
[23:27:03] <Connor_iPad> Pete wants to get his up,and running on modbus. I have some driver code. But
[23:27:49] <Connor_iPad> He wants to get load info. Which it doesn't support. I'll have to mod code to read the register.
[23:28:07] <zee-CNC> what kind of load info
[23:28:17] <zee-CNC> can you not extract that by knowing the output voltage
[23:28:19] <zee-CNC> and current
[23:28:35] <Connor_iPad> Return the current usage.
[23:29:09] <zee-CNC> on my vfd i gotta read from the address '070C' (hex)
[23:29:10] <roycroft> way cool - i even found a 35mm din rail mount socket for that latching relay, so i don't have to do an odd mount
[23:29:16] <zee-CNC> and it will return the output current
[23:30:35] <Connor_iPad> Yea. That's what he wants. Also can return torque data I think.
