[00:18:20] <Cromaglious_> mmmm trailers... mine is a Harbor Fright 4x8 foldable right now... really, really miss my 7x17' trailer...
[00:19:31] <Cromaglious_> using used plywood and 2x2's I made a 8' tall box on it when I moved from Whiteman AFB, MO to california
[00:20:08] <Cromaglious_> then the wif sold it while I was in Korea
[00:20:15] <Cromaglious_> beotch...
[00:20:23] <Cromaglious_> exwif now
[00:22:07] <Cromaglious_> I want to move my fence between the house and kitchen forward to within 2' on the dining room window and build my shop from the fence to within 2' of the kitchen window
[00:22:23] <Cromaglious_> s/on the/of the/
[00:22:55] <Cromaglious_> i think I'd get another 4'
[01:14:27] <Cromaglious_> it would be around 14x12' with 30amps of 240v single phase
[01:14:55] <Cromaglious_> I'd have to look to see what the stove breaker is.. might be a 50amp
[02:11:11] <Deejay> moin
[04:48:48] <XXCoder> im probabky alive
[05:17:10] <jthornton> morning
[05:19:08] <XXCoder> hey
[05:19:16] <XXCoder> how does you glue gunning
[05:20:08] <jthornton> making some feet for the 2020 i3
[05:20:43] <XXCoder> yah saw model
[05:20:44] <XXCoder> nice
[05:20:56] <XXCoder> mine is just 2020 and screw on feet
[05:21:20] <jthornton> yea a 90 brace screwed on for a foot
[05:22:31] <jthornton> I have a couple of linear slides with ball screws http://gnipsel.com/images/core-xy/ball-slide.jpg
[05:22:44] <jthornton> thinking of making a Core XY and using them for the Z
[05:23:04] <XXCoder> fancy
[05:24:15] <jthornton> came off of a machine I built and the customer wanted more travel so they bought new ones, these have never been used
[05:24:19] <jthornton> 16" travel
[05:25:28] <XXCoder> that'd be large print allright
[05:26:02] <DaViruz> jthornton: where can you find tyose, and approx cost new?
[05:28:26] <jthornton> They came as part of a package with drives and servos, I forget the price but I got them from FPE http://fpeautomation.com/
[05:29:07] <jthornton> http://www.fpeautomation.com/supplierpage.php?mfrid=61
[05:29:15] <jthornton> they are tolomatic slides
[05:48:41] <DaViruz> jthornton: thanks, i'll vheck it out
[05:49:31] <jthornton> DaViruz: what are you building?
[05:52:38] <jthornton> https://github.com/justinledwards/BigDelta
[05:54:37] <DaViruz> jthornton: heightcontrol for a waterjet cutter. i've been looking at some chinese units, but i'm still exploring options
[05:55:58] <jthornton> ah the tolomatic slides are top shelf stuff
[06:00:20] <DaViruz> i like the more protected leadscrew
[06:02:53] <jthornton> yea it is sealed up good
[06:07:23] <XXCoder> https://www.thingiverse.com/make:236109 check that out
[06:07:49] <XXCoder> I want to make one :D though I would add a way to force rotate it to make it refgeration test
[06:10:42] <jthornton> cool
[06:41:43] <KreAa_wrk> https://www.youtube.com/watch?v=DgG1Wm2oVgU
[07:05:13] <pink_vampire> http://www.gizmodo.com.au/2015/01/3d-printing-your-own-lawn-mower-sounds-like-a-great-idea-until-it-fails/
[07:05:20] <pink_vampire> why!
[07:06:20] <XXCoder> why not! ;)
[07:06:24] <XXCoder> honestly I wouldnt bother
[07:13:05] <pink_vampire> i want to print something
[07:13:17] <XXCoder> build a delta
[07:13:56] <XXCoder> https://www.thingiverse.com/mdstyle/collections/delta-3d-printer-2020
[07:13:59] <pink_vampire> why?
[07:14:07] <XXCoder> better 3d printer lol
[07:15:42] <XXCoder> seriously dunno lol
[07:15:48] <XXCoder> I dont know what you like
[07:24:04] <pink_vampire> I want to print a mount for the 3d printer head
[07:24:42] <XXCoder> thats great idea
[07:39:09] <pink_vampire> I put good music, and I'm dancing and organizing everything here
[07:40:01] <JT-i3> ouch my print came loose and now it is just a big blob lol
[07:41:34] <pink_vampire> My prints get merge to the tape and i need to file it down
[08:29:13] <pink_vampire> DONE!
[08:40:08] <Jymmm> CaptHindsight: So, I get ready to test; look down in the corner and see a milipedia. bugs = crack(s) and I just had emptied 6 tubes of caulk. Pull off the trim pieces and see bare wood, LOTS of bare wood and cracks big enough to slip 1/4 flat bar through easily. *sigh* I think I should just become a painter at this point!
[08:42:51] <Jymmm> CaptHindsight: As of last night, it's primed, caulked, and painted. Just have to install the trim pieces back today Oh and I HATE nails, had to cut off most of them to get the trim boards off without cracking them. YAY for torx screws =)
[08:48:36] <CaptHindsight> https://www.botfactory.co/page/product
[08:50:30] <Jymmm> CaptHindsight: Other than the price, love it!
[08:54:39] <CaptHindsight> TIJ cartridge on a ChinaCo router
[08:55:55] <Jymmm> Tijuana International Airport ?
[08:56:27] <CaptHindsight> thermal inkjet
[08:56:33] <Jymmm> ah
[08:57:37] <Jymmm> so, does that mean can just grab a inkjet head/cartridge, fill it with solder paste and make pcb's?
[08:58:11] <CaptHindsight> no, you buy their $120 pre-filled cartridge
[08:59:11] <Jymmm> screw that, I'm a cheap bastard. refills by the gallon for only $19.95 + free shipping =)
[09:00:10] <CaptHindsight> https://www.botfactory.co/shop/product/standard-ink-cartridge-307
[09:01:57] <Jymmm> But... isn't there some way to make (flex) pcb's with a laser printer using magnetic ink?
[09:02:15] <Jymmm> err, magnetic toner that is, not ink.
[09:02:41] <CaptHindsight> conductive toner/powder
[09:03:53] <Jymmm> http://www.inkjetsuperstore.com/02-17310-001-MICR?sc=41&category=-141
[09:13:47] <skunkworks> we use that for printing checks
[09:13:48] <skunkworks> :)
[09:38:56] <thomaxo> Hi linuxCNC!
[09:39:13] <skunkworks> Hello!!
[09:39:39] <thomaxo> I'm looking for a book about milling theoretics. What feedrates, spindle speeds, strategy's.. to use and such :)
[09:40:20] <thomaxo> What clamping methods to use and when.. Milling strategy's.. etc :)
[09:42:03] <thomaxo> It can contain difficult math or physics, as long as it doesn't contain very advanced calculus math. (Stuff like gradient's in 3 dimensions, etc)
[09:46:16] <Jymmm> Machinery Handbook ?
[09:47:51] <thomaxo> I'll have a look
[09:48:52] <MacGalempsy> good morning. https://youtu.be/UOhb5VHeN8c
[09:50:47] <pink_vampire> DETROIT..
[09:51:45] <archivist> thomaxo, sometimes you have to make clamps
[09:51:56] <Jymmm> Why cant you use concrete for a furnace/forge?
[09:52:08] <archivist> or design clamping into a job
[09:52:24] <MacGalempsy> All this clown stuff is getting strange!
[09:52:28] <archivist> concrete does not like heat
[09:52:43] <Jymmm> archivist: becomes brittle?
[09:53:15] <archivist> not built for expansion either
[09:53:26] <MacGalempsy> great topic! been going back and forth on recipes
[09:53:35] <pink_vampire> MacGalempsy: https://www.youtube.com/watch?v=GqfAzpTGPGo
[09:53:47] <archivist> thomaxo, part of what you need is gained by experience
[09:54:35] <MacGalempsy> the high heat stuff is 95% aluminum oxide, 4.5% calcium oxide and .5% ferrite
[09:54:56] <MacGalempsy> 10gal comes to $750usd
[09:55:19] <Jymmm> MacGalempsy: Well, I'm even thinking on the clay brick side, like ho they did fireplaces/chimneys of old.
[09:55:21] <thomaxo> True, alot of it is. We're already doing a pretty good job of milling parts in steel. But having read an advanced theoretics book can speed the practical parts up alot :)
[09:55:36] <Jymmm> s/ho/how/
[09:55:41] <thomaxo> Most of what we're doing not is pretty experimental..
[09:55:46] <thomaxo> doing now*
[09:55:50] <archivist> thomaxo, see the sandvik books
[09:56:44] <archivist> title Modern metal cutting
[09:57:02] <MacGalempsy> pink_vampire: lol. they needed a gang to attack
[09:57:21] <thomaxo> Thanks! I'll look it up :)
[09:57:38] <archivist> thomaxo, but that book assumes a good modern solid machine not a home user machine
[09:57:54] <thomaxo> we're covered on that :)
[09:58:00] <MacGalempsy> the furnace forum debates the use of portland. Archivist, any thoughts on that?
[09:58:20] <thomaxo> It's a heidenhain/hardinge/bridgeport machine
[09:58:49] <archivist> MacGalempsy, I would just use cheapo firebrick not much cement needed
[09:59:00] <thomaxo> looks like this one http://www.umcmachinetools.com/uploads/Bridgeport.jpg
[09:59:11] <MacGalempsy> im at the pouring stage
[09:59:38] <MacGalempsy> let me load to a source you can view
[09:59:43] <archivist> pouting metal or what
[09:59:53] <archivist> pouring
[10:00:46] <MacGalempsy> http://picpaste.com/20161011_133830-Q6zovKEr.jpg
[10:00:56] <archivist> my sandvik reading list http://www.collection.archivist.info/searchv13.php?searchstr=sandvik
[10:00:57] <MacGalempsy> no room for bricks
[10:01:47] <archivist> has to be proper fire stuff for that solid
[10:02:23] <archivist> but furnaces get rebuilt often :)
[10:03:07] <MacGalempsy> going to try heat stop 50
[10:03:35] <MacGalempsy> supposedly acme brick carries it
[10:05:33] <MacGalempsy> i wonder how many furnaces are not dried long enough
[10:05:54] <MacGalempsy> so they have problems with a week pour
[10:06:07] <archivist> all those that crack and explode
[10:06:53] <MacGalempsy> many talked about a crumble weak heat face
[10:08:27] <archivist> not surprised if they use the wrong stuff
[10:08:28] <Jymmm> archivist: are those downloadable from you?
[10:08:51] <archivist> Jymmm, no, just get stuff off the sandvik site
[10:09:41] <archivist> no way I would bother scanning stuff available for free elsewhere
[10:19:48] <Jymmm> archivist: I didn't mean it like that, just that there is no link to the document itself, be it your library or it's original source (their website)
[10:20:18] <Jymmm> DIRECT link that is
[11:17:15] <Erant> archivist: Not that you should care a lot, but your searchbox is 'vulnerable' to XSS.

[11:32:05] <pink_vampire> XXCoder: ^^^^^^^^
[11:32:28] <JT-Shop> guy just called me and wanted to place and order over the phone and before I could get done telling him I'm not set up to take credit cards over the phone he hung up!
[11:33:14] <pink_vampire> you can use the paypal interface for that
[11:33:38] <pink_vampire> JT-Shop:
[11:33:47] <JT-Shop> I need to figure that out
[11:35:13] <pink_vampire> you just make a virtual store, then "buy something" but you enter his info
[11:35:46] <JT-Shop> ah I just place his order in my store as him
[11:37:11] <jdh> can you buy me a tormach with his CC?
[11:38:15] <DaViruz> i'll take a beer.
[11:42:14] <archivist> erant er what
[11:43:44] <CaptHindsight> https://www.owasp.org/index.php/Cross-site_Scripting_(XSS)
[11:44:42] <archivist> I want proof not an explanation
[11:59:51] <FloppyDisk525> JT-shop how's that 3d printer working... My buddy built one like this:
[11:59:52] <FloppyDisk525> https://www.aliexpress.com/store/product/2016-Micromake-3D-Printer-Pulley-Version-Linear-Guide-DIY-Kit-Kossel-Delta-Auto-Leveling-Large-Printing/2128317_32747409645.html
[11:59:58] <FloppyDisk525> Can't believe how cheap they've gotten...
[12:09:25] <CaptHindsight> now that 3D printers are ~$200 we should start seeing their effects on manufacturing subsequently the economy...
[12:09:58] <CaptHindsight> no more having to run to the store for anything
[12:10:12] <roycroft> 3d printers are still extremely expensive to operate
[12:10:24] <roycroft> and likely will be for the indefinite future
[12:11:00] <CaptHindsight> just a few watts of power and $10/lb filament
[12:11:08] <roycroft> and a buttload of time
[12:11:12] <roycroft> that is almost the entire expense
[12:11:27] <roycroft> just last night i was reading an article about a 3d printed peristaltic pump
[12:11:35] <roycroft> what immediately struck me was the discussion of printing hte parts
[12:11:56] <roycroft> two of the parts are cylinders with a axial hole
[12:12:04] <roycroft> the article said it takes 19 minutes to print each one
[12:12:09] <roycroft> that is pretty damn expensive
[12:12:26] <CaptHindsight> a real mustache takes days to grow, a printed one only takes hours
[12:12:39] <roycroft> a piece of 1/2" aluminium rod 3 inches long costs a few pennies for materials
[12:12:53] <roycroft> and maybe a minute of time on the lathe to bore the hole
[12:13:41] <roycroft> 3d printing will never supplant traditional machined part fabrication
[12:13:49] <roycroft> it will complement traditional methods
[12:13:53] <CaptHindsight> I was promised that they would revolutionize manufacturing
[12:14:07] <roycroft> by whom?
[12:14:12] <roycroft> donald trump, the serial liar?
[12:14:15] <CaptHindsight> reprap
[12:14:23] <roycroft> then they are liars as well
[12:14:31] <CaptHindsight> and all the 3D printer websites
[12:18:03] <roycroft> they are all liars
[12:18:32] <roycroft> lies and the lying liars that tell them, i say
[12:18:39] <CaptHindsight> how do I know that you are telling me the truth?
[12:18:59] <roycroft> you don't
[12:19:06] <roycroft> i might be one of the lying liars
[12:19:14] <roycroft> i might be lying to you when i tell you i'm a liar
[12:19:20] <roycroft> there
[12:19:21] <CaptHindsight> ah hah, but they said they are telling me the truth
[12:19:25] <roycroft> now you can go norman on us
[12:20:26] <CaptHindsight> so they were mostly just a bunch of scammers trying to sell 3D printers and parts?
[12:22:53] <IchGucksLive> hi
[12:27:00] <FloppyDisk525> Meh, or eh... 3d printers are supposed to be printing pizza's. All from techno-ists who need to sell ads w/ ridiculous articles.
[12:27:26] <CaptHindsight> FloppyDisk525: I think I found Dilbert in the pics from that 3D printer link on alibaba
[12:27:42] <CaptHindsight> but he's gained a few pounds
[12:27:46] <FloppyDisk525> I do think the metal printing would be cool and can have some advantages over machining, especially complex parts.
[12:27:51] <FloppyDisk525> Capt - :-)
[12:28:14] <FloppyDisk525> But, the cost of a 3d metal printer is prohibitive...
[12:28:37] <CaptHindsight> how much would it have to cost?
[12:28:49] <FloppyDisk525> Dunno...
[12:28:53] <FloppyDisk525> I'm not good at that.
[12:29:16] <FloppyDisk525> Depends is the answer... On what you're printing and the cost of the machining.
[12:30:32] <CaptHindsight> ChinaCo CO2 laser tubes are cheap enough
[12:30:42] <CaptHindsight> if it can engrave it can sinter
[12:31:22] <FloppyDisk525> yes... We should be building one...
[12:31:25] <FloppyDisk525> :-)
[12:36:29] <FloppyDisk525> I really want to build a dlp/sla 3d printer, better resolution. time is the issue...
[12:42:50] <CaptHindsight> http://www.ebay.com/itm/RECI-100W-Co2-700x500mm-Laser-Engraving-Cutting-Machine-Engraver-Cutter-USB-/112141443625 can't someone just modify this and give them the plans?
[12:43:14] <CaptHindsight> then we all can just order them for $2500
[12:43:28] <SpeedEvil> DLP are parallel
[12:44:31] <CaptHindsight> get Amazon to home deliver Argon
[12:44:32] <Loetmichel_> *MAAAAN* what a (static charged) MESS!... http://www.cyrom.org/palbum/main.php?g2_itemId=16429&g2_imageViewsIndex=1 http://www.cyrom.org/palbum/main.php?g2_itemId=16432 that pvc swarf clings to ANYTHING
[12:47:03] <CaptHindsight> SLA printer at Walmart for ~$1k https://www.walmart.com/ip/Xyzprinting-Inc-Nobel-1.0-3D-Printer-Clear-Grey/51894025
[12:48:24] <SpeedEvil> Loetmichel_: water sprayer with leetle anti static funiture polish
[12:49:01] <Loetmichel_> or a second vacuum to suck it away as it is generated...
[12:49:11] <SpeedEvil> or that, yes
[12:49:16] <CaptHindsight> salt water :)
[12:49:19] <Loetmichel_> <- will alsk the boss to pay for a second vacuum
[12:49:48] <Loetmichel_> ... or a side channel vacuum pump for the vacuum table
[12:50:27] <Loetmichel_> the $50 shopvac isnt built to run 8+ hours continously against near no airflow anyway ;)
[12:50:40] <CaptHindsight> whats the conductive component in conductive furniture polish?
[12:50:59] <CaptHindsight> conductive/antistatic
[12:52:07] <CaptHindsight> plastic tent with coolant mist?
[12:53:27] <CaptHindsight> conductive mesh machine enclosure?
[12:53:49] <SpeedEvil> CaptHindsight: it is some wierd long-chain carbon thing I think that I forget
[12:59:47] <CaptHindsight> SpeedEvil: not sure what they rely on for its antistatic property
[13:00:43] <Tom_itx> lazy atoms
[13:00:46] <CaptHindsight> https://en.wikipedia.org/wiki/Quaternary_ammonium_cation is used to repel dust
[13:07:50] <CaptHindsight> https://en.wikipedia.org/wiki/Glycol_ethers probably just a glycol since it acts as the solvent as well as a coating

[13:20:25] <CaptHindsight> Axisface for Linuxcnc https://ibin.co/2yEz1zoUZ5jZ.jpg
[13:21:17] <Deejay> photoshopped :D
[13:21:53] <CaptHindsight> just a mock up for feedback
[13:24:56] <skunkworks> heh - that is my screenshot of axis ;)
[13:25:26] <skunkworks> (temp comp spindle length)
[13:42:38] * Loetmichel_ edited a 58000 lines gcode file today to fit in some retaining tabs...
[13:42:49] <Loetmichel_> that was fun... NOT...
[13:50:03] <nikre> Loetmichel_, is there a tool to modify gcode. i know gcode ripper only
[13:50:33] <Loetmichel_> nikre: i used mousepad ;)
[13:50:41] <nikre> that is some tool
[13:50:42] * Deejay uses a text editor for this
[13:50:43] <Loetmichel_> and something called "gray matter" ;)
[13:51:12] <nikre> would splitting the gcode on some axis work for you?
[13:51:41] <nikre> i had found this http://www.scorchworks.com/Gcoderipper/gcoderipper.html
[14:09:55] <CaptHindsight> nikre: many just use a simple text editor
[14:15:23] <yasnak> What could I use to build a prototype material loader/unloader? Can't find exactly what I need, so I'm looking to build one. Would be a hopper with thousands of shafts that need to be pushed up to a stop, laser marked, then removed and reloaded.
[14:16:22] <CaptHindsight> what size are the shafts?
[14:16:47] <yasnak> All less then 0.5" in diameter by 12"
[14:16:58] <yasnak> most less then 0.2" x 8"
[14:17:24] <CaptHindsight> so various lengths and diameters?
[14:17:34] <yasnak> if it could orient based on part features (aka, part has hex and needs laser marks based off hex orientation) that be kickass
[14:17:44] <yasnak> yeah various but nothing large
[14:18:15] <archivist> one of those vibrating bin things
[14:18:32] <yasnak> yeah I thought about that
[14:18:45] <yasnak> Before I go all in just wanted to see if there is something else I'm overlooking
[14:19:13] <archivist> they have the clever orientation
[14:19:36] <CaptHindsight> machine vision for detecting the hex vs round?
[14:19:47] <archivist> but one off batch or constant production
[14:19:56] <yasnak> I mean we're production
[14:20:12] <yasnak> We're paying someone right now to sit at a laser and load/unload manually.
[14:20:18] <CaptHindsight> do they all roll? are they all round?
[14:20:28] <yasnak> We need more production, 10 hours a day won't keep up
[14:20:35] <yasnak> yes, all round
[14:20:42] <CaptHindsight> do they arrive in random diameters?
[14:21:30] <yasnak> I mean, I would like to do different diameters. The parts are all very close tolerance within each specific part being made
[14:21:51] <CaptHindsight> stack them and roll them down and incline to a belt with a stop
[14:21:53] <gregcnc> laser live tools? https://sme.org/MEMagazine/Article.aspx?id=8589934760&taxid=1460
[14:22:06] <CaptHindsight> and/an
[14:23:09] <CaptHindsight> https://www.youtube.com/watch?v=K_iivPagxMg
[14:23:14] <yasnak> hmmm, that actually might be a really simple solution for the parts with just a single band on them. guess i was trying to be too inclusive of the ones that need orienting.
[14:23:27] <yasnak> i'll roll with that and hopefully that will cover at least half of the parts lol
[14:23:55] <yasnak> yeah thats nice, its just shitty when you get to running parts that are 0.062" in diameter x 10"
[14:24:06] <yasnak> much easier when you've got large diameters lol
[14:24:34] <CaptHindsight> instead of that pusher I'd use a belt
[14:25:04] <CaptHindsight> whats the smallest dia?
[14:25:15] <yasnak> right now? 0.062
[14:25:29] <yasnak> but next week it could be 0.005". my boss seems hell bent on making my hair go away
[14:26:18] <CaptHindsight> my usual list of questions: max dia, max length, min dia, min length, all round? same material? how straight are the thinner ones?
[14:26:27] <CaptHindsight> etc etc etc
[14:28:04] <CaptHindsight> https://www.youtube.com/watch?v=H-M_oGJeV4E another way to separate them
[14:28:30] <CaptHindsight> a starwheel for each dia
[14:31:45] <CaptHindsight> https://youtu.be/alSJhopw_b4?t=46s or a belt to catch them one by one
[14:49:39] <CaptHindsight> gregcnc: http://milwaukee.craigslist.org/for/5761001724.html
[14:51:47] <gregcnc> BTM has listed a few older machines this year
[14:56:13] <gregcnc> http://milwaukee.craigslist.org/tls/5783371300.html small hobby stuff, ive seen a few of those rockfords listed but no info online
[14:57:39] <CaptHindsight> I find the best deals late winter-spring
[15:01:18] <CaptHindsight> all I want is a ~8" x 12" lathe with air bearings
[15:02:48] <gregcnc> what kind of tolerance are you making parts to?
[15:03:31] <CaptHindsight> making machines to make machines that will be sub-micron
[15:04:39] <gregcnc> graound near lapped finishes requried?
[15:07:22] <CaptHindsight> also optics
[15:14:48] <jesseg> hey guys anyone ever heard of trump knee mills? I seen one for sale, worn acme screws, wondering how much I oughta offer
[15:15:05] <jesseg> it's not a big one, it's probably as small as they make knee mills. ROC.
[15:15:18] <jesseg> K3V
[15:15:20] <jesseg> oops K2V
[15:15:41] <gregcnc> there are actually many air bearing spindles on thebay no idea what it would take to turn one into a useful lathe though
[15:16:26] <jesseg> oh it's Atrump,
[15:17:27] <CaptHindsight> gregcnc: I'll probably end up building it
[15:18:55] <CaptHindsight> I have several linear servo positioners are well with crossed roller bearings
[15:19:25] <CaptHindsight> lots of linear servo parts
[15:22:24] <gregcnc> air bearing to get high spindle speed?
[15:28:01] <CaptHindsight> https://www.youtube.com/watch?v=sFrVdoOhu1Q
[15:28:01] <CaptHindsight> High precision air bearing CNC lathe and grinder
[15:37:34] <gregcnc> Capthindsight, are the parts really 1micron range? Hardinge super precision or similar not capable?
[15:40:20] <gregcnc> I also found shapemastertool.com for diamond tools which should come in handy
[15:42:52] <gregcnc> though you may need single crystal
[15:55:45] <gregcnc> nice garage size mill https://chicago.craigslist.org/nwc/bfd/5825356098.html
[15:56:25] <CaptHindsight> secret price
[15:56:56] <gregcnc> probably $60k+
[15:57:22] <gregcnc> not sure what the 50k spindle costs
[15:57:36] <CaptHindsight> if you have to ask you can't afford it
[16:01:03] <gregcnc> ooh french and cheap https://chicago.craigslist.org/nch/tls/5825045322.html
[16:02:18] <gregcnc> dang if i had room i'd like me a manual metric lathe
[16:03:25] <CaptHindsight> hmm, maybe I could convert it to inches
[16:10:53] <yasnak> trying to make a suture cutter, to cut ultra-high-molecular-weight polyethylene.
[16:11:26] <yasnak> Used an EDM to make razor sharp cutting edges on some 17-4 H900, this stuff literally deforms the cutting edges.
[16:15:05] <gregcnc> cutting kevlar is tricky too. scissors for that have little top rake and serrations
[16:15:16] <yasnak> is there any good reads on that?
[16:15:56] <yasnak> engineer and I are taking shots in the dark, debating going to some 440 stainless otherwise...
[16:16:08] <yasnak> I mean this stuff is 45 RC now ha
[16:18:01] <gregcnc> you can take fiskars and stone the edge flatter to cut kevlar, but you'll have to do it often. I have a pair of plastic frame Ginghers for kevlar. never looked into the details
[16:28:25] <Nick-Shop> how do I disconnect an output from a signal in terminal so I can test the actual output in halcmd in terminal. Rather not play with the hal file.
[16:40:48] <JT-Shop> http://linuxcnc.org/docs/2.7/html/hal/basic-hal.html#_unlinkp
[16:41:48] <Deejay> gn8
[16:42:19] <Nick-Shop> Thanks - trying to teat the raise turret selenoid
[16:44:59] <pink_vampire> the machine run on 1700mm/min
[16:49:18] <pink_vampire> http://ustre.am/1qGHt
[16:49:23] <pink_vampire> print live!!
[16:49:48] <Nick-Shop> JT - raise turret & stop solenoid both are working - thanks for the info
[16:51:31] <pink_vampire> the house is a bit shaking
[17:03:30] <andypugh> pink_vampire: Is that the neigbours, or something geological?
[17:04:29] <andypugh> I _demand_ that somebody knows how a an embedded GaldeVCP tab can know that it’s selected. :-)
[17:08:35] <cradek> andypugh: (I know nothing about this but) can you do the opposite and make touchy poke something in the tab when the visibilty changes?
[17:09:33] <andypugh> I can. (probably) but this is my lathe macros reworked for touch-screen, and I would like it to work for anyone.
[17:10:28] <cradek> seems like it's ok if you have to add something to touchy
[17:11:25] <JT-Shop> what about the GtkWidget focus-in-event and focus-out-event
[17:11:26] <andypugh> I have been looking at it. But it would need to be every UI
[17:11:33] <cradek> oh I see
[17:12:14] <andypugh> I am starting to think that the UIs that support embedded tabs might actually need to learn to do this.
[17:12:38] <AndChat|234416> hey hey all
[17:12:41] <cradek> could send the child processes signals...
[17:12:48] <andypugh> As a minimum they probably need to pass a handle to the parent. Perhaps thsy do?
[17:13:27] <cradek> child = Popen(cmd.split()); self._dynamic_childs[xid] = child
[17:13:33] <andypugh> JT-Shop: Not looked at those yet. An exhaustive search of all signals to all children might be required.
[17:13:37] <cradek> touchy keeps track of their pids
[17:13:48] <andypugh> Yeah, been looking there.
[17:14:14] <pink_vampire> http://i.imgur.com/gEX654C.png
[17:14:40] <cradek> surely there oughta be some way to show all the events happening
[17:14:45] <andypugh> I even added child.add_property(‘gladevcp-your-turn’, False) but it turns out that add_property only exists somewhere else.
[17:14:47] <JT-Shop> as you go up the ladder you find a bunch of signals that are inherited by the notebook
[17:15:14] <andypugh> yeah.
[17:15:30] <cradek> you guys know more about this than I do...
[17:15:37] <andypugh> It’s one of those tunnel up or runnel down questions
[17:16:44] <andypugh> cradek: Yes, I think that there is a way to show every event. But there are a _lot_. “expose” looks good, but triggers almost every mouse move..
[17:18:53] <cradek> hard to say on a touchscreen exactly what mouse motion is
[17:18:58] <cradek> that doesn't sound like a winner
[17:21:52] <cradek> ugh I know I wrote most of that, but after only 7 years it looks pretty foreign
[17:22:34] <JT-Shop> I sure know that feeling
[17:27:32] <JT-Shop> I hope this 1144 stressproof threads nicely
[17:31:54] <andypugh> cradek: Python is so very powerful, but so incomprehensible, there are so many things you could use, you always wonder if the one you _are_ using is a stupid choice. Python is like having servants. C is like having transistors. I prefer C, I know exactly what tools I have in my box.
[17:32:50] <JT-Shop> and GTK is even worse imho
[17:32:59] <t12> until you have to write complex datastructure stuff from scratch
[17:33:29] <t12> as long as it doesnt need to be as fast as possible its ususally easier in a high level language
[17:34:06] <t12> like trying to do what say numpy does in C
[17:34:12] <t12> is burn months of time vs days
[17:35:05] <cradek> t12: but 20 years later it'll compile and run
[17:35:16] <cradek> it's all tradeoffs
[17:35:56] <t12> hence the current academic situation
[17:36:05] <t12> of you might have a very powerful supercomputer available
[17:36:16] <t12> but if someones 30yr old fortran doesnt run on it, noone cares
[17:36:41] <t12> (was re: blue gene/L)
[17:37:20] <andypugh> talking about compiling and running, on the mailing list, what’s Russell’s problem? I care because Russell is an old friend in RL
[17:37:22] <cradek> heh to write a program today that should run unmodified in 20 years I wonder if you'd be better off picking f77 or c99
[17:37:35] <cradek> I'd think c99...
[17:37:51] <andypugh> x86 assembler?
[17:38:01] <t12> just keep the binary?
[17:38:08] <t12> if it doesnt need to be modified
[17:38:30] <andypugh> Or, the other way, Excel VBA.
[17:38:30] <t12> depends on the program i guess
[17:38:32] <cradek> andypugh: no clues, except it sounds very very weird
[17:38:36] <t12> if you had to do math, f77 likely
[17:38:46] <t12> otherwise you're stuck with f77 -> c wrappers for most math
[17:39:28] <cradek> andypugh: I'd think he's not running what he thinks he is (the config maybe?) or he has mixed/confused rip/packaged or something else excessively weird
[17:40:09] <cradek> if it's really saying bad character 'z' in unmodified splash screen axis.ngc, then he's running a config that doesn't have Z
[17:40:30] <cradek> maybe he nuked his config by running master and autoconverting it?
[17:40:36] * cradek grasps at straws
[17:41:16] <cradek> oh he also says he has inexplicable tool table errors
[17:41:30] <cradek> he is surely running a wrong config ... somehow
[17:41:49] <cradek> at startup, linuxcnc says on stdout which config directory and ini file it's using
[17:42:33] <cradek> upgrading to precise to fix whatever this is is a very terrible idea
[17:43:12] <andypugh> Maybe we should ask him to look at that. He’s an old Linux dude, his business is Linux-based frozen-food control systems.
[17:43:29] <cradek> is he near you? I predict a different set of eyes could spot the trouble
[17:43:46] <cradek> it's so easy to get mixed up and then not see things
[17:43:58] <andypugh> About 100 miles away
[17:44:02] <cradek> :-/
[17:44:52] <cradek> I don't understand how he started talking about upgrading python
[17:45:12] <cradek> oh he tried installing NativeCAM
[17:45:29] <cradek> that's the install that copies stuff over your system-installed packaged files
[17:45:40] <cradek> or something
[17:45:51] <cradek> I don't remember the details but I recall having a bad feeling about it
[17:46:02] <andypugh> Aye, the Dewey branch is probably a better bet for most,
[17:46:05] <cradek> dewey has fixed that stuff up and it's in a linuxcnc branch now
[17:47:13] <andypugh> (for context, this is Russels company home-page, He’s old-school: http://www.lls.com )
[17:50:32] <cradek> hm can't dpkg check to see if any of a package's files got nuked since install?
[17:51:15] <cradek> andypugh: I guess my advice is try to figure out if NativeCAM did something, and then try to figure out how to undo it
[17:51:49] <cradek> that's pretty high-level advice, but sounds like it might be ok for him
[17:52:21] <cradek> but I can't really imagine how it could be so screwed up
[17:54:21] <cradek> Nativecam.com a venture of eCorp.com Inc. eCorp is the worlds largest virtual domain development incubator on the planet
[17:54:25] <cradek> bluuuurggh
[17:56:13] <gregcnc> lolz i just got 8' of 1.25" 2011 round bar in a flat rate envelope
[17:57:47] <andypugh> Oh, no. Not another EMC corporation problem in the offing?
[17:58:33] <tiwake> andypugh: ..?
[17:59:05] <andypugh> tiwake: LinuxCNC used to be called EMC2. Then lawyers came a-calling.
[17:59:46] <andypugh> gregcnc: That’s not really fair, is it?
[17:59:56] <tiwake> andypugh: right, but, there is another one?
[18:00:18] <andypugh> Yeah, Cradek’s comment
[18:00:55] <gregcnc> eh it says one rate, any weight. i received it btw
[18:01:18] <cradek> hard to predict. maybe wasn't the best name to pick, but what is? every word is already used.
[18:01:21] <andypugh> cradek: It’s rather neat how NativeCAM displays the stock, but I have a feeling it does it by fooling Gremlin with block-delete.
[18:01:37] <gregcnc> the ebay listing said flat rate envelope, turns out it wasn't in error
[18:02:00] <cradek> I should try dewey's branch...
[18:02:05] <andypugh> Would have possibly been better to invent another interface into Gremlin for work features.
[18:02:38] <andypugh> gregcnc: Do they sell Osmium?
[18:05:00] <gregcnc> oops it as 1.125", but the price was excellent for 2011. http://www.ebay.com/sch/discountmetalsales1/m.html
[18:06:11] <andypugh> To really break the system you could order Hassium bars, but you would need expedited shipping “269Hs, has a half-life of approximately 9.7 seconds, although an unconfirmed metastable state, 277mHs, may have a longer half-life of about 130 seconds. More than 100 atoms of hassium have been synthesized to date.[2]"
[18:07:27] <andypugh> “Hassium is expected to have a bulk density of 40.7 g/cm3, the highest of any of the 118 known elements and nearly twice the density of osmium,[3]”
[18:07:51] <SpeedEvil> But couldn't be cooled enough to be solid
[18:07:56] <SpeedEvil> Or possibly liquid
[18:08:27] <gregcnc> I got 2 sticks of 1.75x1.5x12 aluminum in the mail this summer. The postman said here's your lead. i didn't say anyhting
[18:08:29] <andypugh> No, it would be a solid at room temperature. If you could get enough atoms together at the same time.
[18:08:38] <SpeedEvil> err - no
[18:09:12] <SpeedEvil> It would emit ~a gigawatt of heat per microgram
[18:09:29] <andypugh> Well, yes, but apart from that :-)
[18:10:15] <JT-Shop> seems that 3D printing is like helicopters everything has a trade off
[18:10:35] <SpeedEvil> https://en.wikipedia.org/wiki/Fission-fragment_rocket#Dusty_Plasma - is related
[18:11:32] <Tom_L> JT-Shop, rewrite the rules
[18:12:28] <andypugh> JT-Shop: As far as helicopter trade-offs go, I find this one fascinating: https://en.wikipedia.org/wiki/Kaman_K-MAX
[18:13:36] <BeachBumPete> Hey folks whatsgoingon? ;)
[18:13:50] <andypugh> How’s the weather?
[18:14:15] <BeachBumPete> well today its kinda overcast and rainy but its much cooler after the storm passed
[18:14:19] <BeachBumPete> you?
[18:14:32] <andypugh> Rainy. Cool. Very safe.
[18:15:06] <BeachBumPete> isnt it like always cold and rainy there?
[18:15:41] <JT-Shop> that is an interesting one with meshing rotors
[18:15:50] <JT-Shop> and no tail rotor
[18:16:21] <andypugh> JT-Shop: Yes, fascinating isnt it? And can lift more than it’s own weght in payload.
[18:16:36] <andypugh> BeachBumPete: Define “cold” :-)
[18:16:46] <BeachBumPete> less than warm :)
[18:16:56] <JT-Shop> that is an amazing feat for a heli
[18:17:25] <andypugh> I haven’t turned the heating on yet, so it can’t be that cold.
[18:17:32] <BeachBumPete> we used to call them whistling shitcans and screaming chickens when I was in the Coast Guard.
[18:18:09] <BeachBumPete> I will say that my power bills are MUCH cheaper here ;)
[18:18:37] <JT-Shop> I should get out my Benson plans
[18:18:45] <BeachBumPete> I am working with a local rollback wrecker to bring my VMC over to the house sometime soon
[18:19:10] <BeachBumPete> the good news is that they can probably do it tomorrow or Friday after I get off work
[18:19:42] <BeachBumPete> the bad news is the $75 bucks I paid the guy in Tennessee to move it Aint gonna happen here :)
[18:21:31] <JT-Shop> I just switched from my summer carhartt t shirts to the regular ones last week
[18:23:15] <JT-Shop> https://www.youtube.com/watch?v=5Sz7eUj46aE
[18:23:36] <JT-Shop> your evening song
[18:26:17] <JT-Shop> BeachBumPete: you getting settled in?
[18:27:07] <BeachBumPete> JT-Shop yeah man we are quite comfortable now hehe really enjoying the new house it's so nice to NOT have a bunch of renovation work to do.
[18:28:11] <JT-Shop> I hear ya rework is a PIA
[18:28:27] <JT-Shop> I fell off the CNC wagon and got a 3D printer lol
[18:28:40] <BeachBumPete> yeah the house we had in Tennessee we worked on basically from the day we bought it to the day we sold it
[18:28:52] <JT-Shop> ouch that sucks
[18:29:07] <BeachBumPete> well we made some money on it when we sold it but it did suck yeah
[18:29:13] <JT-Shop> wears valley was real nice but the traffic sucked
[18:29:45] <BeachBumPete> I have like a very mild interest in 3d printing....mostly just to say I have done it LOL
[18:30:16] <JT-Shop> the one me and XXCoder have is $218 delivered from Hong Kong
[18:30:34] <JT-Shop> actually it's kinda neat to do
[18:30:39] <BeachBumPete> oh yeah is it worth a shit?? thats pretty cheap
[18:31:15] <JT-Shop> yea, you have to fiddle a bit to get it "right" when putting it together but it prints pretty good
[18:31:27] <BeachBumPete> I have often thought the idea of adding a head to the VMC would be kinda fun
[18:31:45] <JT-Shop> some things have a loose fit so you need to put shim tape on them lol
[18:32:03] <BeachBumPete> so its a chinese KIT
[18:32:56] <JT-Shop> https://www.aliexpress.com/item/Full-Metal-Frame-3D-Printer-Professional-3d-Color-Printer-with-8GB-SD-Card-LCD-One-Roll/32705186296.html?spm=2114.13010608.0.0.3Rg6aw
[18:33:06] <JT-Shop> a chinlee prusa i3
[18:33:35] <BeachBumPete> ya know honestly that does not LOOK too bad really
[18:33:38] <JT-Shop> http://gnipsel.com/images/prusa-i3-clone/
[18:34:10] <anarchos2> maybe a dumb question...but where can i get the newest version of gmoccapy?
[18:34:20] <JT-Shop> first thing I made is this http://www.thingiverse.com/thing:1808823
[18:34:35] <JT-Shop> it's part of LinuxCNC
[18:34:50] <BeachBumPete> I thought the first thing you were supposed to make was a Yoda head? :)
[18:35:08] <_methods> pete you made it
[18:35:08] <JT-Shop> the Z limit bracket sucked
[18:35:27] <BeachBumPete> _methods made what?
[18:35:32] <JT-Shop> next I made http://www.thingiverse.com/thing:1818785
[18:35:33] <_methods> thru the storm
[18:35:37] <JT-Shop> a way to payoff
[18:35:39] <_methods> how'd you guys fare
[18:35:53] <BeachBumPete> I have seen worse thunderstorms around here ;)
[18:35:59] <_methods> haha
[18:36:03] <_methods> yeah not too bad here either
[18:36:08] <_methods> power was out for a couple days
[18:36:19] <BeachBumPete> yeah we lost power for a couple days too
[18:37:05] * JT-Shop only looses power for a few moments any more... got tired of that crap
[18:37:36] <BeachBumPete> we borrowed a generator and my friend Mark loaned me a portable AC unit so we were reasonably comfortable
[18:38:03] <BeachBumPete> how much does the filament generally cost?
[18:39:15] <andypugh> anarchos2: Hmm, good question
[18:40:46] <andypugh> anarchos2: I think that updates now go into LinuxCNC directly, so if you get the latest LinuxCNC you have the latest Gmoccapy
[18:40:48] <JT-Shop> good quality pla is $30 a KG I get it at http://atomicfilament.com/
[18:40:54] <BeachBumPete> is that thing complete and ready to run?
[18:41:04] <JT-Shop> they even have carbon filled petg
[18:41:19] <JT-Shop> http://atomicfilament.com/collections/petg-3d-printer-filament-us-made-with-free-shipping/products/carbon-fiber-black-petg-pro
[18:42:00] <BeachBumPete> how long did it take you to print that triangle shaped filament roll stand?
[18:42:02] <JT-Shop> you just have to put it together and it has everything you need to run
[18:42:18] <JT-Shop> let me go see
[18:42:30] <andypugh> anarchos2: Depending on how “latest” you want, you can point the synaptic package manager to other places and get anything from “latest” to “so new it might not work: http://buildbot.linuxcnc.org
[18:42:36] <BeachBumPete> do you run it with linuxCNC?
[18:43:25] <JT-Shop> you can slic3r can output LinuxCNC G code
[18:43:44] <andypugh> JT-Shop: That’s temptingly cheap, but anything I buy next has to be non-cartesian for aesthetic reasons I don’t care to exlain. :-)
[18:43:44] <JT-Shop> I use the ramps board and marlin firmware that came with it
[18:43:51] <BeachBumPete> slicer is the CAM right?
[18:44:01] <JT-Shop> yea
[18:44:14] <JT-Shop> andypugh: get a kossel
[18:44:31] <JT-Shop> BeachBumPete: it's slic3r
[18:44:46] <BeachBumPete> yeah I know I just didnt want to reach for the 3 ;)
[18:44:52] <JT-Shop> slicer is a medical program
[18:44:55] <JT-Shop> lol
[18:45:02] <JT-Shop> https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&cad=rja&uact=8&ved=0ahUKEwjn_pf4stbPAhWMGCwKHRfyC-UQFggeMAA&url=http%3A%2F%2Fslic3r.org%2F&usg=AFQjCNFRlhg6QuRrwL_xhb8bwzjCDOyATA
[18:45:13] <JT-Shop> stupid google sorry
[18:45:20] <JT-Shop> http://slic3r.org/
[18:45:52] <BeachBumPete> well I gotta go to Home Despot for a bit. BBL. thanks for the tips
[18:45:58] <JT-Shop> cura is another slicer
[18:46:07] <JT-Shop> and there are a couple more
[18:46:18] <JT-Shop> see ya later
[18:46:38] <andypugh> I wrote my own, runs inside Inventor, No STL facets
[18:47:13] <JT-Shop> cool
[18:47:21] <andypugh> Which was a mildly eccentric thing to do as I don’t have a printer.
[18:47:30] <JT-Shop> I wondered about the stl files
[18:47:39] <JT-Shop> but your ready for one now
[18:48:11] <JT-Shop> you just need an extruder and a hot end...
[18:49:58] <JT-Shop> the printed parts are pretty cool with a honey comb inside
[18:51:06] <andypugh> My slicer was aimed at DLP, really
[18:51:24] <JT-Shop> DLP?
[18:51:28] <FloppyDisk525> kisslicer
[18:52:03] <FloppyDisk525> I had some print that wouldn't work well in slic3r and a friend recommended... Maybe slic3r is better now.

[18:52:24] <FloppyDisk525> DLP - overhead projector w/ UV light and bath
[18:52:39] <FloppyDisk525> Much better resolution, I really want to make one...
[18:52:52] <FloppyDisk525> roger moore, eh..
[18:53:03] <JT-Shop> oh yea those are cool
[18:53:36] <andypugh> That is actually his real name, I know him,
[18:54:13] <FloppyDisk525> Cool!
[18:55:03] <andypugh> If you look at his other videos there is one taken by a drone. He has a _nice_ house to go with the nice workshop
[18:55:46] <FloppyDisk525> his deckel is pristine, looks great...
[18:56:14] <andypugh> FloppyDisk525: Have you seen the things he is making?
[18:56:21] <FloppyDisk525> No...
[18:56:50] <andypugh> FloppyDisk525: http://www.f1-2000.co.uk
[18:56:57] <JT-Shop> my redesign on the 2020 foot looks much better
[18:57:06] <andypugh> Try the conrods…
[18:57:35] <FloppyDisk525> I've seen that car, it's beyond amazing.
[18:57:41] <JT-Shop> oh he is the one making the Ferrari engine
[18:57:46] <JT-Shop> that is cool
[18:57:47] <FloppyDisk525> Fwd'd to a friend who is a scuderia fan...
[18:58:15] <andypugh> The printer was to make lost-PLA castings of engine parts
[18:58:59] <JT-Shop> did he make ceramic molds from the pla part?
[18:59:07] <JT-Shop> I want to do that
[18:59:59] <andypugh> He made plaster-of Paris moulds. I am not sure that’s the best way. Perhaps a traditional thin investment has advantages.
[19:00:12] <andypugh> His results were mixed.
[19:00:42] <andypugh> I think he has decided to mill from solid, hence: https://www.youtube.com/watch?v=AlPWFT73Qns
[19:00:48] <JT-Shop> I want to make ceramic molds and cook them in the kiln
[19:02:01] <JT-Shop> then cast some aluminum parts
[19:06:11] <JT-Shop> that part came out much better
[19:06:20] * JT-Shop wanders inside now
[19:26:50] <witnit> JT-i3: you around?
[20:26:50] <yasnak> Who ever thought suture would be such a pain in the ass to cut. Not me...I thought the actual design of the cutter itself would be the hard part. :/
[20:40:12] <pink_vampire> the first pint is done!!!
[20:50:53] <witnit> cheers!
[20:51:54] <FloppyDisk525> pint? Nice...
[21:01:12] <AndChat|234416> drinking something good?
[21:58:05] <norias> hi
[22:15:34] <pink_vampire> hi norias
[22:15:43] <norias> how are you?
[22:26:56] <pink_vampire> I can show you
[22:27:28] <pink_vampire> norias:
[22:29:13] <norias> ?
[22:30:30] <pink_vampire> http://i.imgur.com/SxrY0Uc.png
[22:30:42] <pink_vampire> http://i.imgur.com/gYbmssr.png
[22:31:11] <norias> so.. printing thing
[22:31:12] <norias> s
[22:32:01] <pink_vampire> on my cnc mill
[22:32:59] <norias> neato
[22:33:19] <norias> i saw some rumors of that at IMTS
[22:34:24] <pink_vampire> rumors?
[22:35:13] <norias> i.e. i think they were showing it off
[22:35:18] <norias> but i didn't go check it out
[22:37:20] <eeriegeek> pink_vampire do you have a link to the extruder you are using?
[22:37:33] <pink_vampire> yes
[22:38:19] <pink_vampire> http://i.imgur.com/QDxPJMV.png
[22:38:26] <pink_vampire> eeriegeek:
[22:38:54] <pink_vampire> it's too strong
[22:39:00] <AR__> so you just run your cnc mill in reverse and it becomes a 3d printer
[22:39:17] <pink_vampire> almost
[22:39:25] <CaptHindsight> inverse mill
[22:39:49] <pink_vampire> i'm use the rapid move on 1700mm/min for prints
[22:43:14] <t12> what does everyone consider max RPM from a nema23 stepper to be
[22:52:11] <Cromaglious_> depends on the induction of the motor and mass of the rotor
[22:57:31] <CaptHindsight> please define max RPM, with no load? or with rated max load?
[22:59:55] <t12> max anyone has ever seen one run, under whatever application
[23:00:09] <t12> no/minimal steploss
[23:00:15] <CaptHindsight> http://www.orientalmotor.com/technology/articles/article-speed-torque-curves-for-step-motors.html
[23:02:17] <t12> continuous fighting of this trinamic stepper driver here
[23:03:03] <pink_vampire> t12: about 100-200 rpm fro usable torque
[23:05:41] <pink_vampire> t12 for high rpm the best way to go is servo
[23:05:59] <pink_vampire> and now it's not that expensive
[23:06:18] <t12> just curious what people have pulled off
[23:08:20] <pink_vampire> i'm using name 34 servo for each the axis
[23:08:33] <pink_vampire> the extruder is stepper
[23:11:23] <Cromaglious_> I'm using crappy piddley chinese nema 23 3040 stock motors doing good to get 900mm/m
[23:11:39] <Cromaglious_> at 27vdc
[23:18:59] <CaptHindsight> t12: http://www.kollmorgen.com/en-us/products/motors/stepper/hi-torque/km-series/ are good up to ~3krpm
[23:20:29] <CaptHindsight> http://www.motortong.com/Stepper-Motors/specifications/3000-rpm_Stepper-Motors.html
[23:21:02] <t12> dang
[23:21:05] <t12> 4.3kozin
[23:21:14] <t12> on thats 42
[23:21:34] <t12> i'm writing this driver code for these trinamic stepper drivers
[23:21:38] <t12> but its kinda rough
[23:22:03] <t12> theres coupled dividers for velocity, ustepping, acceleration
[23:22:31] <t12> so for high speeds, you run out of divider
[23:22:37] <t12> need to rejiggle everything
[23:22:46] <t12> it keeps track of its position, so then when you change the ustepping rate
[23:23:02] <t12> you also need to go update all the internal position counters
[23:23:32] <t12> maybe unecessary though if the max 256ustep rpm is as fast as is reasonable
[23:23:40] <CaptHindsight> 3k also for https://www.sinotech.com/products/motors/stepper-motors/microstepper-motors/
[23:30:06] <CaptHindsight> t12: http://www.trinamic.com/products/integrated-circuits/stepper-power-driver one of these?
[23:30:23] <CaptHindsight> are their registers all similar?
[23:30:37] <t12> not sure, i've only been working with one of their parts
[23:30:43] <t12> the uh
[23:31:27] <t12> TMC429 + TMC262
