[00:10:55] <shanker_> hello there
[00:11:04] <shanker_> so I just smoked my TB6560 CNC Stepper Motor Driver Controller Board
[00:11:17] <shanker_> will anyone tell me a good cnc controller board that wont go up in smoke
[01:34:30] <Flipp_> hey all, anyone around that can answer a question about threaded rods/leadscrews/ballscrews?
[01:42:30] <anarchos> i most likely can't answer your question but i'd like to see it :P
[01:43:30] <Flipp_> how do people get fast linear movement out of threaded rods/leadscrews/ballscrews?
[01:43:52] <Flipp_> I've got a nema17 motor + an A4988 driver, and I can't seem to get it to go any faster than ~350 RPM
[01:44:10] <Flipp_> which, on a threaded rod that's got a TPI of 12, translates to a whopping 0.5" per second :(
[01:47:48] <anarchos> the specs say 1A without active cooling, or 2A with a heatsink and/or fan
[01:47:58] <anarchos> maybe get yourself a heat sink and up the power?
[02:11:01] <archivist> Flipp, you need to use a servo for high speed, steppers lose torque as the rpm rises
[02:12:29] <Flipp_> archivist: yeah, that's what I'm seeing. for my application, I dont' think I need much torque
[02:12:36] <Flipp_> just moving a pick and place head up and down
[02:13:09] <Flipp_> probably no more than 40mm or so
[02:13:16] <archivist> use a coarse thread
[02:14:26] <archivist> eg a ball screw with something like a 5mm pitch
[02:14:40] <Deejay> moin
[02:50:43] <Flipp_> archivist: any tips on cutting leadscrews?
[02:56:25] <archivist> you would be better off with a ball screw for reliability
[02:57:52] <archivist> cutting screws is easy enough on a screw cutting lathe or mill with a 4th axis, but does need support during the cutting if long
[02:59:45] <archivist> this is how I made a silly proportion thin coarse screw for a clock http://www.collection.archivist.info/searchv13.php?searchstr=merlin+worm
[03:01:04] <archivist> that is 4mm diameter
[03:05:25] <ReadError> Flipp_ using openpnp?
[03:07:57] <Flipp_> ReadError: my own stack (just bit banging on an Atmega2560 at the moment)
[03:08:13] <Flipp_> archivist: man, I wish I had access to that kinda hardware O.o
[03:08:40] <Flipp_> archivist: I had to cut a screw early today by hand with a hacksaw D:
[03:08:48] <Flipp_> archivist: the perils of living in an apartment :(
[03:09:18] <archivist> I built that from scrap and a few new bits and some machined
[03:10:11] <archivist> buy ready made is no access to machines, join a hackspace
[03:10:31] <Flipp_> archivist: sadly there aren't many well equipped in the seattle area :/
[03:11:10] <archivist> or a class for machinists or a model engineering club
[03:11:12] <Flipp_> but yeah. I end up paying a bit more, but I usually get stuff cut/formed before I buy
[03:12:16] <archivist> you can just carry on using the same screw and accept the slowness, or gear up (belt or gears) from the stepper to screw
[03:12:49] <archivist> be aware that leadscrews whip at speed if long and thin
[03:14:41] <Flipp_> whipping = vibrating off axis along the axis of rotation?
[03:15:05] <archivist> there are some internet critical speed calculators for leadscrews http://www.nookindustries.com/EngineeringTool/Index
[03:15:17] <Flipp_> awesome, thanks
[03:15:35] <archivist> imagine a skipping rope
[04:50:31] <mutley_> ok so just want to say thanks to a cpl guys from yesterday for their help and patience with my questions, archivist and a cpl others gave me the info i needed to get this running right http://imgur.com/RDxwSr5
[04:50:46] <mutley_> http://imgur.com/TdkCDle
[04:51:30] <mutley_> http://imgur.com/ZMe1E9z these now drop into the gearbox where they replace worn gears, they drop on erfectly and run smooth as silk
[04:52:04] <mutley_> that came of the machine at about 3am, thank heavens the neighbour has gone away for the weekend.....it turned out all my issues were down to a gantry that wasnt straight
[04:53:13] <archivist> I know the spastic fur problem http://gears.archivist.info/gears/fan_gears.html
[04:53:41] <archivist> nice result though
[04:54:33] <kfoltman> mutley_: milled or printed?
[04:54:48] <archivist> milled
[04:54:59] <mutley_> ha sastic fur, year its a bit furry, they clean up well though, just a little tedious scraping of the flash once the main part of that fur is pulled away but a litle patience and they soon come u nice
[04:55:14] <mutley_> this is the thing, when selling people just think these are "bits of plastic"
[04:55:37] <mutley_> kfoltman: milled, i have done some printed ones too which came up nice but sadly wouldnt be functional
[04:55:39] <archivist> I do the fur removal with a scalpel and a microscope
[04:56:22] <mutley_> yea i pull it off with needle nose pliers, then its a sharp blade under a magnifying lamp
[04:56:49] <mutley_> only about 10 minutes to clean each one if that once you site down and get a rythm going
[04:57:32] <kfoltman> archivist: great idea!
[04:58:26] <archivist> these were done with a gear milling cutter http://www.collection.archivist.info/archive/DJCPD/PD/2014/2014_01_19_Cyprus_gears/IMG_1735.JPG
[04:58:50] <archivist> parting off was not so good
[04:59:08] <kfoltman> archivist: as in, on a lathe or...?
[04:59:13] <kfoltman> with a hob
[04:59:48] <mutley_> so today im going to make one of those centrometers, brass bar, steel ground rod and some grub screws to have a larger radius now that i have seen the importance relevance and fact that i need to do that test 2 we were talking about yesterday
[04:59:55] <kfoltman> archivist: the stuff on the left and the right of each gear - is that just unfortunate lighting, or is there an excess of material in there?
[04:59:58] <archivist> no a milling cutter on the 5 axis mill
[05:00:21] <mutley_> archivist: thy look familiar? automotive aplication?
[05:00:42] <archivist> no a toy dancing frog band
[05:01:13] <mutley_> see now if i was in a different place id swear for sure that was a piss take answer lol
[05:01:26] <archivist> but when someone really wants something repaired ....:)
[05:02:12] <archivist> https://www.youtube.com/watch?v=yjh5bz-IApM
[05:02:23] <mutley_> btw that image i posted with the spindle and bit inside the gear, that was doing 20krpm so im seriously surprised how sharp the photo is
[05:03:04] <mutley_> right second coffee and cig on the go, time to get cracking and churn out a few more
[05:03:35] <archivist> all I have this morning is a laptop to fix the OS on
[05:44:32] <ssi> lord this is a time of day which shouldn't exist
[05:44:53] <archivist> its late
[05:45:13] <ssi> :)
[05:45:19] <ssi> yesterday at this time it was late
[05:45:21] <ssi> today it's early
[05:45:28] <ssi> it's all about perspective heheh
[05:46:04] <ssi> https://pbs.twimg.com/media/BsatjbjIIAEotj7.jpg:large
[05:46:09] <ssi> base frame of my laser table assembled
[05:46:17] <ssi> tonight when I get home from sailing I can start working on Y motion :D
[05:46:20] <archivist> 11:30 ish and on second coffee, that is a definition of late morning
[05:46:37] <ssi> 6:30a here D:
[05:46:56] <archivist> not enough crap in that room error
[05:47:47] <ssi> that's my spare "empty" room
[05:48:18] <ssi> I am 80% through putting floors in my house (last fall), and that's the room I'm supposed to move my bedroom into so I can floor in there
[05:48:21] <archivist> I have no clue what empty looks like
[05:48:21] <ssi> heh
[05:49:06] <Jymmm> archivist: Look up at the ceiling; now pretend that's the floor; that's "empty"
[05:49:54] <archivist> nope, you must realise crap piles reach the ceiling in a non empty room
[05:49:55] <Jymmm> ssi: I hope those legs will be braced
[05:50:02] <ssi> they will
[05:50:30] <ssi> I'll add a shelf underneath for electronics, water pump, and material storage
[05:50:35] <Jymmm> are those legs 1x1 ?
[05:50:37] <ssi> ya
[05:50:45] <archivist> spindly
[05:50:46] <ssi> er 20mmx20mm but close enough :P
[05:50:49] <Jymmm> and the crossbars are 1x2?
[05:50:51] <ssi> yep
[05:51:16] <Jymmm> why not have the legs 2x2?
[05:51:37] <ssi> 2x2 extrusion isn't a thing, plus it's not necessary
[05:51:40] <ssi> this stuff is plenty strong enough
[05:52:24] * kfoltman took a hacksaw to his CNC machine today
[05:52:42] <Jymmm> ssi: what do you mean "isnt a thing" ?
[05:52:51] <ssi> http://www.mcmaster.com/#t-slotted-framing/=stfbl3
[05:55:14] <shanker_> any one have a good request for a control board
[05:55:28] <ssi> what kind of control board
[05:55:36] <shanker_> cnc
[05:56:22] <ssi> can you be more specific? :P
[05:56:36] <shanker_> I had a TB6560 CNC Stepper Motor Driver Controller Board
[05:56:42] <shanker_> but it just went up in smoke
[05:56:44] <shanker_> sorry
[05:56:53] <shanker_> I was looking for the model
[05:57:07] <shanker_> but yeah I am using Mach3
[05:57:25] <ssi> well so that's two things
[05:57:31] <ssi> that's a breakout and stepper drivers
[05:57:35] <ssi> personally I like dedicated drives
[05:57:39] <shanker_> yeah
[05:57:52] <shanker_> it is two things not that you mention it
[05:57:52] <Jymmm> ssi: It sorta exists... http://www.ebay.com/itm/8020-T-Slot-Aluminum-Extrusion-10-S-2020-x-48-N-/220331409128?pt=LH_DefaultDomain_0&hash=item334cc67ee8
[05:57:56] <ssi> it's a lot more expensive that way, but they're more robust
[05:58:16] <archivist> they are known for going up in smoke, specially with bad motor connections
[05:58:25] <ssi> Jymmm: yeah I know, but 8020 is balls expensive as a system, plus it's not compatible with the stuff I'm using
[05:58:55] <shanker_> archivist humm I just rewired the moters too
[05:58:59] <shanker_> and poof
[05:59:20] <Jymmm> ssi: ah, you using 80ouncer huh? lol
[05:59:32] <ssi> eh?
[05:59:38] <shanker_> the machine was taken aprt about a year ago. I moved and then wanted to re-vamp the project and poof
[05:59:39] <Jymmm> 40 ouncer
[05:59:58] <Jymmm> colt 45
[06:00:07] <shanker_> I was thinking about using grbl
[06:00:07] <ssi> steel reserve mostly
[06:00:28] <kfoltman> ssi: ?
[06:00:35] <shanker_> but I only have l298ns
[06:00:37] <archivist> we dont support mach or grbl in here
[06:00:41] <ssi> kfoltman: I dunno I'm babbling back at jymmmmmmmmmm
[06:00:47] <shanker_> I know
[06:00:50] <ssi> it's too early in the morning for coherency
[06:00:51] <shanker_> you use linuxcnc
[06:00:52] <kfoltman> ssi: ok, I won't interrupt you then ;)
[06:00:55] <archivist> linuxcnc does more that either
[06:01:01] <archivist> than
[06:01:20] <kfoltman> shanker_: I use grbl, hoping to upgrade to linuxcnc soon
[06:01:22] <ssi> also a lot of the folks here using linuxcnc tend to use much more robust (and expensive) hardware
[06:01:44] <shanker_> kfoltman are you using the shield
[06:01:56] <Jymmm> ssi: My only concern using the 1x1 is twisting/flexing/bowing
[06:02:08] <kfoltman> shanker_: I have my own breakout board made from my own protoboard with arduino nano plugged into it
[06:02:13] <ssi> Jymmm: it'll be fine... it's a frickin laser, not a router
[06:02:21] <ssi> and once it's all boxed up, it's rock solid
[06:02:36] <kfoltman> shanker_: you could use a protoshield or whatever, no rocket science there
[06:02:44] <shanker_> kfoltman what do you think about using a dual-h bridge to drive the moters
[06:02:51] <kfoltman> shanker_: just remember to use 0.9f version of grbl, the previous ones had some rather nasty bugs
[06:03:00] <kfoltman> shanker_: forget it :)
[06:03:07] <archivist> get good robust drivers
[06:03:08] <shanker_> yeah I was reading about that
[06:03:18] <shanker_> ok forgotten
[06:03:26] <kfoltman> shanker_: the 6560 aren't really that bad if you're operating them well within their safety limits
[06:03:41] <kfoltman> shanker_: or at least that's my experience so far, YMMV
[06:04:00] <kfoltman> shanker_: I'm using 2 of those board + one makeblock microstep driver, all from a 24V 5A power supply
[06:04:11] <kfoltman> they still work
[06:04:17] <shanker_> yeah that is nice
[06:04:31] <kfoltman> but my current limit is <=2A
[06:04:54] <shanker_> so if you had to go and do it from scrach after your board just blew up what would you go with. 3axis nema 23
[06:05:19] <kfoltman> shanker_: I don't know, I'd probably get a monthly supply of 6560s ;)
[06:05:33] <shanker_> right and just replace
[06:05:45] <kfoltman> shanker_: the makeblock driver doesn't seem that bad either, and it's in a proper metal case
[06:05:56] <kfoltman> depends on how much power you need really
[06:06:10] <kfoltman> geckodrives are supposed to be much better than any of those
[06:06:11] <shanker_> just cncing mdf
[06:06:28] <kfoltman> but they also cost about 5x price of the 6560s
[06:06:32] * archivist gets leadshine drivers and does not need constant replacement
[06:06:47] <kfoltman> archivist: I *touch wood* haven't had to replace any of my 6560s yet
[06:06:57] <kfoltman> I think the biggest problem with them is inflated specs
[06:06:59] <shanker_> lol
[06:07:35] <kfoltman> archivist: on the other hand, I fried several smaller drivers (stepsticks)
[06:08:10] <shanker_> o yeah on my 3d printer I have killed like 10
[06:08:17] <shanker_> stepsticks suck
[06:08:20] <kfoltman> shanker_: amen
[06:08:48] <kfoltman> shanker_: well, for learning etc. 6560s are probably adequate, especially if you have one or two spares
[06:09:00] <shanker_> so the 6560 is what blew up on my board
[06:09:11] <kfoltman> I don't know your board
[06:09:21] <kfoltman> it might have been anything
[06:09:21] <shanker_> I know you dont
[06:09:25] <shanker_> right
[06:09:35] <kfoltman> anyway, for any commercial use etc. you're better off following archivist's advice, he knows what he's doing
[06:09:49] * archivist admits nothing
[06:09:55] <shanker_> ha
[06:10:20] <shanker_> Shoot I am still learning. I have tried to build a cnc 3 times
[06:10:29] <kfoltman> for home use, if you can afford the occasional 'machine breaks and ruins the workpiece' kind of events, it might be an overkill
[06:10:29] <shanker_> and every time I fail
[06:10:51] <kfoltman> shanker_: mine is generally working, but has some teething problems
[06:10:52] <shanker_> But I am having fun at it
[06:11:00] <kfoltman> and ruins 2 out of 3 jobs I give it
[06:11:04] <archivist> I only built one once but I modify as I go along
[06:11:22] <kfoltman> but at least I know what I have to fix, which is good :)
[06:11:56] <shanker_> yeah the first one I built was out of plastic and metal tubes and build my own liner motaion
[06:12:16] <shanker_> it fell aprt
[06:12:24] <kfoltman> hah yeah, not surprising
[06:12:29] <shanker_> this one I am working on is out of 8020
[06:12:32] <kfoltman> it would be OK for PCB exposer or something like that
[06:12:41] <shanker_> yeah
[06:12:47] <kfoltman> I used plywood and commercial linear motion components
[06:13:00] <kfoltman> linear rails, ballscrews
[06:13:27] <shanker_> I just dont know if. I am going to buy a new TB6560
[06:13:32] <shanker_> or find something else
[06:13:34] <kfoltman> the cost was rather enormous (>1000 euro for everything) but at least I didn't have half of the typical problems people have with cheap parts
[06:14:09] <shanker_> like it smoking the house up and your wife getting mad at you
[06:14:11] <shanker_> =)
[06:14:16] <ssi> shanker_: take it as an opportunity to upgrade
[06:14:24] <shanker_> true
[06:14:28] <kfoltman> shanker_: you have an integrated board with multiple drivers?
[06:14:29] <shanker_> ssi I agree
[06:14:34] <shanker_> yes
[06:14:35] <ssi> get some dedicated drives and either a good breakout or even better, mesa interface
[06:14:38] <shanker_> 3 drivers
[06:14:56] <kfoltman> shanker_: I use single axis driver boards, so it's easier to replace if it fails
[06:15:04] <shanker_> I like the dedicated drivers will work
[06:15:07] <ssi> tell me about your motors, size/torque, and power supply
[06:15:34] <shanker_> ok nema 23's they have 24v 2amp I think
[06:15:56] <shanker_> 1/8th step
[06:15:56] <kfoltman> shanker_: what current per phase in the configuration you're using?
[06:16:06] <kfoltman> shanker_: also, 4 phase? 8 phase? serial, parallel?
[06:16:12] <shanker_> 4 phase
[06:16:19] <shanker_> parallel
[06:16:25] <ssi> so for inexpensive drives, I use keling stuff... archivist mentioned leadshine, i think these are rebranded leadshine
[06:16:28] <ssi> http://www.automationtechnologiesinc.com/products-page/kl-stepper-drivers/kl-4030-24-40vdc-3-0a-microstepping-driver
[06:16:32] <ssi> but something along those lines will probably work well for you
[06:16:39] <ssi> yeah that's a lot more money than the TB6560
[06:16:42] <ssi> but it's a lot more good too
[06:16:56] <kfoltman> ssi: those seem quite cheap, even comparing to the Chinese boards
[06:17:17] <ssi> kfoltman: that's $44 for a single axis drive
[06:17:23] <ssi> vs $55 for three axes plus breakout
[06:17:30] <kfoltman> $15 for tb6560 without a case, $44 for this in a proper box
[06:17:49] <kfoltman> geckos are like $100 per axis or even more
[06:17:56] <ssi> yeah geckos are too expensive
[06:18:12] <shanker_> still If i am going to spend about 300 in 8020 might as well do it right
[06:18:17] <ssi> the g203v is supposed to be a very good drive, but I don't know personally because I won't spend $130 for a single axis of drive :P
[06:18:27] <ssi> the keling/leadshine type drives are FINE
[06:18:30] <kfoltman> ssi: the "three axis plus breakout" seems like a bad idea overall
[06:18:37] <ssi> if you want to spend a little more, get the digital drives
[06:18:48] <ssi> kfoltman: oh I agree completely, I don't use anything like that anymore
[06:18:52] <ssi> my first one blew up real early
[06:19:06] <shanker_> http://www.ebay.com/itm/CNC-TB6560-3-5A-4-Axis-Stepper-Motor-Driver-Board-Controller-4-Engraving-Machine-/400637530827?pt=LH_DefaultDomain_0&hash=item5d47db92cb
[06:19:13] <shanker_> so that is the board I smoked
[06:19:20] <ssi> http://www.automationtechnologiesinc.com/products-page/digital-stepper-motor-driver/digital-stepper-driver-kl-4042d-heat-sink-is-included
[06:19:25] <ssi> there's the digital version of that drive
[06:19:30] <ssi> $70 apiece isn't cheap
[06:19:33] <kfoltman> shanker_: well, yeah, avoid these, they're *too* cheap
[06:19:43] <ssi> but I just ordered three of those in a slightly higher voltage ($90 each) for my laser table
[06:19:46] <shanker_> right
[06:20:01] <shanker_> ooo lazer table
[06:20:08] <shanker_> ssi I bet that is fun
[06:20:11] <ssi> and when you're ready to move to linuxcnc, get yourself a mesa 7i76 kit and you'll be in business
[06:20:23] <kfoltman> ssi: 'digital' drives? how are they doing microstep *without* digital/PWM?
[06:20:25] <ssi> shanker_: I hope so; I'm still in the building phase now... laser tube and optics are still in the mail :)
[06:20:38] <kfoltman> optics... scary stuff
[06:20:39] <kfoltman> :(
[06:20:43] <shanker_> what kind of tube did you get ?
[06:20:52] <ssi> kfoltman: heh
[06:20:57] <shanker_> or gas i mean
[06:21:03] <ssi> shanker_: bottom of the barrel cheap chinese 40W co2
[06:21:14] <shanker_> they dont look that bad
[06:21:20] <ssi> which'll get replaced with something a little better once everything's working well
[06:21:39] <shanker_> ssi have you seen the one on buildyourcnc.com
[06:22:12] <ssi> yea
[06:22:27] <shanker_> https://www.buildyourcnc.com/blackToothLaserCutterAndEngraver.aspx
[06:22:32] <shanker_> that one is sick
[06:22:37] <ssi> too much MDF for my taste :)
[06:22:50] <shanker_> right if it goes up in flames
[06:23:03] <ssi> here's the beginning of my table
[06:23:03] <ssi> https://pbs.twimg.com/media/BsatjbjIIAEotj7.jpg:large
[06:23:16] <ssi> also I settled on a 2x4' work area, and it's turning out HUGE heheh
[06:23:25] <ssi> it's like 34x68" outside
[06:23:40] <shanker_> that is nice
[06:23:59] <ssi> https://fbcdn-sphotos-e-a.akamaihd.net/hphotos-ak-xfa1/t31.0-8/10365407_10100426695720862_6809920225001781781_o.jpg
[06:24:25] <shanker_> yeah that is going to be huge
[06:24:29] <SpeedEvil> ssi: I'm planning a 1.2*2.4*0.3m or so bed router.
[06:24:42] <ssi> SpeedEvil: nice
[06:24:52] <ssi> my plasma table is 48x48" work area, and it's pretty flippin huge too
[06:24:54] <SpeedEvil> ssi: It's easy enough to start 'Ok, now, a 60cm beam is quite rigid enough...
[06:25:15] <SpeedEvil> ssi: but then it all adds up to a pretty huge envelope
[06:25:18] <ssi> yep
[06:25:38] <ssi> plasma table is made out of 2x4" x 3/16" wall rectangle steel tube welded together
[06:25:44] <ssi> and it weighs a couple hundred pounds empty
[06:26:45] <jthornton> my plasma is 36 x 52 but I can slide a 4' x 8' sheet in and cut part at a time
[06:27:22] <jthornton> my wife looked in the plasma cam ad that I get every once and a while and wants the butterfly chair
[06:27:37] <shanker_> what do you all think about http://www.ebay.com/itm/CNC-3-Axis-stepper-Driver-3-5A-Breakout-interface-board-for-Router-system-kit-/281221235650?pt=LH_DefaultDomain_0&hash=item417a1783c2\
[06:28:13] <ssi> jthornton: I'm still having issues with the Z axis trying to make offset removal moves hugely fast and stalling
[06:28:13] <Jymmm> jthornton: Happy Wife = Happy Life, so GIT ER DONE!!!
[06:28:44] <ssi> shanker_: suspiciously cheap, but a step in the right direction ;)
[06:28:50] <jthornton> ssi, what correction velocity are you using?
[06:29:14] <shanker_> ssi i know cheap but it is still a hobbie
[06:29:16] <ssi> 0.00005
[06:29:34] <shanker_> once i get it up and running a can make a few dollars off of it
[06:29:39] <shanker_> then I will upgrade
[06:29:50] <jthornton> I'm using 0.00002
[06:30:09] <jthornton> more than that and I saw voltage fluctuations
[06:30:32] <ssi> the other thing that's odd...
[06:30:44] <ssi> I get huge voltage fluctuations on small holes, which probably isn't surprising
[06:30:48] <ssi> on long cuts it's stable
[06:30:56] <ssi> but it looks like the torch climbs away from the work and the arc gets pretty long
[06:31:16] <jthornton> how small of a hole is small?
[06:31:22] <ssi> I'm wondering if either my voltage sensing correction isn't right, or if my initial cut height isn't right
[06:31:26] <ssi> 1/4"
[06:31:48] <ssi> and that's at 200ipm or more
[06:31:52] <jthornton> I usually don't cut that small of a hole
[06:31:53] <ssi> so it probably doesn't even have time to stabilize
[06:31:58] <ssi> yeah they don't do great hehe
[06:33:15] <shanker_> I would say it is all about the right documentation too
[06:33:44] <shanker_> the board I got from china didnt have any
[06:33:59] <shanker_> it came with a cd loaded with like 3000 modles on it
[06:34:11] <shanker_> figures why i blew it up
[06:34:37] <ssi> beware: you can blow up almost any stepper driver
[06:34:50] <ssi> the g203v is supposed to be "unkillable" but it's also $130 apiece
[06:34:57] <ssi> just about anything cheaper can be killed
[06:35:38] <ssi> anyway, I'm off to go sailing
[06:35:41] <ssi> back this evening :)
[06:36:18] <shanker_> have fun
[06:36:23] <shanker_> and thank you for the info
[07:15:02] <archivist> bugger fleabay item 281379252031 wont fit in my car to bring home
[07:23:25] <kfoltman> 2 tonnes
[07:23:26] <kfoltman> nice
[07:30:12] <archivist> note the size of the column, solid and large
[07:33:21] <syyl_ws> lil' hogger ;)
[07:34:02] <syyl_ws> maybe not the right machine for a 1mm endmill
[07:34:35] <syyl_ws> but to produce a smoking pile of blue chips...right machine ;)
[07:34:39] <archivist> a production miller for castings that wont notice a hard chill
[07:35:10] <syyl_ws> yeah
[07:35:10] <syyl_ws> :D
[07:35:24] <syyl_ws> might be fun to run
[07:35:27] <syyl_ws> at least once ;)
[08:04:03] <Loetmichel> archivist: get a bigger car ;.)
[08:04:20] <archivist> I wish
[08:04:46] <archivist> current lack of income stops me getting too many toys
[08:05:37] <archivist> but I did just bid on a smaller bit of ooooh shiny
[08:30:18] <kfoltman> archivist: link? :D
[08:30:45] <archivist> seeekwet /me wants to win it :)
[08:31:37] <archivist> when it goes out of my price league
[08:34:52] <kfoltman> archivist: not going to bid on it anyway, just curious :) but no rush of course :)
[10:58:42] <Jymmm> What is: θ
[11:04:07] <Nebukadneza> heho
[11:07:34] <humble_sea_bass> https://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-xfp1/t1.0-9/10150538_724256364292860_1587600914_n.jpg
[11:07:46] <humble_sea_bass> rolling lawsuit
[11:19:25] <XXCoder2> fancy lawsuit device
[11:20:01] <Jymmm> that board looks awfully thin
[11:20:11] <XXCoder2> its very strong
[11:20:23] <XXCoder2> even if its adaminium I wouldn't use it
[11:20:39] <XXCoder2> its not toughness issue, its safety issue lol
[11:20:53] <Jymmm> Why, the kid upsidedown looks like he's having fun =)
[11:21:03] <Jymmm> Weeeeeeeeeeeeeeeeeeeeeeeeeeeeeee
[11:28:50] <XXCoder2> lol
[11:32:46] <IchGuckLive> hi all B)
[11:32:52] <XXCoder2> yo
[11:33:11] <IchGuckLive> shanker_: still with us
[11:33:41] <IchGuckLive> Nebukadneza: heho
[11:34:27] <Nebukadneza> mhhh, say -- do i understand right that linuxcnc cannot be used to send commands to those grbl-compatible controller devices..?
[11:35:05] <IchGuckLive> most of this got als oa busmode
[11:35:40] <archivist> Nebukadneza, yes that is right
[11:36:00] <IchGuckLive> Nebukadneza: there is only one post from you i the logs so we need some more infos to help you on your problem
[11:36:17] <archivist> Nebukadneza, linuxcnc is the controller
[11:36:57] <IchGuckLive> are you retrofitting a device or building a new one
[11:37:42] <Nebukadneza> i'm getting a 4-axis styrofoam hotwire CNC cutter from a friend soon, and it's fitted with a smoothie-something controller thingy
[11:37:54] <SpeedEvil> Nebukadneza: fun
[11:38:10] <IchGuckLive> oh thats my big goal i got 10 foam cutters
[11:38:16] <archivist> that is a mach cough 3 toy
[11:38:34] <XXCoder2> 10 of em wow
[11:38:41] <Nebukadneza> as documentation sounds limited on that device, and its surrounding "ecosystem", so i'd have liked it//hoped for if linuxcnc would somehow supported it :D
[11:38:47] <Nebukadneza> archivist: mach *cough* 3?
[11:38:57] <IchGuckLive> http://www.youtube.com/watch?v=AMp6QVtOoZw
[11:39:02] <IchGuckLive> here is one
[11:39:37] <XXCoder2> unwatchable videpo
[11:39:39] <archivist> mach3 is less good at realtime control so they hand off to an external smoothy box
[11:39:46] <IchGuckLive> the 5 axis XYUVB is here http://www.youtube.com/watch?v=wT_ndXDZ0DU
[11:39:47] <XXCoder2> not only handheld, but constant motion
[11:40:07] <IchGuckLive> a casel in one shot
[11:40:16] <Nebukadneza> archivist: i thought that smoothieboard thingy wanted "grbl"?
[11:40:36] <archivist> no it is a similar concept to grbl
[11:40:37] <SpeedEvil> http://www.mauve.plus.com/Chinese-Lantern.jpg - my polystyrene cut mould lantern
[11:40:43] <SpeedEvil> It's a fun thing to do
[11:40:54] <IchGuckLive> i also made a post for foam on heekscad to get the g-code for mashines in one shot out of dxf no Z involved
[11:40:59] <SpeedEvil> (the base only)
[11:41:16] <Nebukadneza> so in any case, these things are made so i send them my gcode in some way or other, and they do the realtime magic for me, right?
[11:41:32] <Nebukadneza> linuxcnc on the other hand, does the realtime magic on the linux box?
[11:41:47] <archivist> you just about got it there :)
[11:42:36] <archivist> except the smoothy will expect something from mach3
[11:42:52] <Nebukadneza> ok
[11:42:56] <os1r1s> Nebukadneza: If you are talking about a smoothieboard, that is different than a smoothstepper
[11:43:09] <Nebukadneza> yes, the "smoothieboard"
[11:43:20] <os1r1s> Nebukadneza: I believe emc2 will work with smoothieboard
[11:43:34] <Nebukadneza> oh!
[11:43:45] <os1r1s> There is some sort of passthrough people have used to control repraps
[11:43:55] <IchGuckLive> smothieboard uses the ethernet connector
[11:44:15] <os1r1s> That is different than a smoothstepper which is windows/mach3 specific
[11:44:16] <Nebukadneza> IchGuckLive: yes, or serial over usb
[11:44:30] <Nebukadneza> os1r1s: sorry, didn't know there were so "closely-named" producst
[11:44:34] <Nebukadneza> *products
[11:44:55] <os1r1s> No worries. Happy to help someone out
[11:46:29] <archivist> os1r1s, are you sure seems it is a g code driven device
[11:46:40] <Nebukadneza> mh
[11:46:51] <archivist> and linuxcnc does not output g code to another device
[11:46:53] <Nebukadneza> do you have a link to some documentation concerning that pass through mode? i seem too blind to find it atm
[11:46:55] <os1r1s> archivist: It is, but people have used repraps with emc2.
[11:47:21] <archivist> repraps and emc/linuxcnc is not smoothieboard
[11:47:39] <archivist> are you making the right connection
[11:47:46] <os1r1s> Nebukadneza: http://reprap.org/wiki/EMCRepRap
[11:48:15] <os1r1s> Nebukadneza: If you join #smoothieware, there will be people familiar with that controller
[11:48:28] <Nebukadneza> mh, right too
[11:48:29] <Nebukadneza> thanks!
[11:48:55] <os1r1s> archivist: Yes, I am. I'm very familiar with both smoothieboard and smoothsteppers
[11:49:29] <os1r1s> I don't know emc2 well at all though, but I'm aware that people have done that
[11:49:35] <archivist> but not soothieboard to linuxcnc by the look of it
[11:54:57] <Nebukadneza> mh
[11:55:06] <Nebukadneza> all this cnc stuff is pretty confusing to newbies like myself :D
[12:04:15] <gene78> hm2/5i25 question: How do I access the GPIO pins on a 5i25 at base-thread rate, addf says it need floating point
[12:05:29] <IchGuckLive> gene78: can you paste the hal
[12:05:44] <IchGuckLive> or is it a postgui problem
[12:06:05] <gene78> I expect, is pastebin working with firefox now?
[12:06:45] <gene78> The hal is incomplete as yet.
[12:07:27] <IchGuckLive> yes http://pastebin.com/
[12:08:41] <IchGuckLive> hi operator

[12:37:26] <operator> naja feinheiten
[12:37:47] <operator> und dann muss man sich mit der Steuerung anfreunden
[12:38:14] <IchGuckLive> ;-)
[13:06:34] <marmite_> http://www.cnczone.com/forums/musical-instrument-design-and-construction/233054-ibanez-talman-tc530-pickguard.html maby somone here have a good idea for me :D
[13:08:13] <archivist> measure and draw one up
[13:08:52] <marmite_> aint the easiest thing to draw
[13:09:10] <CaptHindsight> life is full of challenges :)
[13:09:19] <marmite_> :P
[13:09:54] <archivist> but driving to the Marmite factory is trivial for me
[13:10:16] <marmite_> :P
[13:10:33] <marmite_> gotta love that marmite
[13:10:41] <CaptHindsight> do you have one to copy? or just the pictures?
[13:10:41] <archivist> that tells you where I am, 5 miles from it
[13:11:01] <marmite_> i do have a broken one
[13:11:50] <CaptHindsight> sounds like you're pretty close to having a template
[13:12:32] <marmite_> scaning in then cadding ontop of the image
[13:14:12] <CaptHindsight> depending on the scanner you might not even have to do any CAD, there are image to G-code utils as well
[13:14:52] <marmite_> yeah, i have tested out scan 2 cad with kinda bad results
[13:15:07] <CaptHindsight> you need good scan data
[13:15:18] <archivist> I tend to measure
[13:16:02] <marmite_> measure would be the best, but really hard due to the form och the plate for me :D
[13:20:24] <IchGuckLive> marmate you need a DXF
[13:20:27] <IchGuckLive> ?
[13:20:34] <IchGuckLive> shoudt i give you
[13:20:36] <marmite_> that would be the best option yes
[13:20:42] <marmite_> if you had one yeah :D
[13:20:46] <IchGuckLive> so wait some minutes
[13:24:58] <archivist> mount a web cam on your machine, place old unit on table, then jog it, and read the x y locations, ie a cmm
[13:29:38] <marmite_> archivist: that was a smart idea
[13:29:57] <Swapper_> anyone that have any tips on how to program HAL to make a output high when the spindle RPM is over 3000rpm on the spindle ?
[13:30:38] <IchGuckLive> COMPare
[13:33:05] <IchGuckLive> marmite_: what size do you have in meter
[13:33:25] <IchGuckLive> so i decide your guitarr size
[13:33:36] <IchGuckLive> $7$ 7/8
[13:33:41] <IchGuckLive> 4/4
[13:33:54] <marmite_> 4/4
[13:34:02] <IchGuckLive> ok
[13:40:10] <kfoltman> you need a different guitar to play songs in 7/8? *ducks*
[13:41:06] <archivist> a metric guitar
[13:41:31] <kfoltman> a metric modulation guitar?
[13:41:34] <IchGuckLive> hi raymondhim
[14:00:53] <jthornton> a k sure does have a hard time comprehending
[14:02:35] <IchGuckLive> uw hi
[14:02:45] <IchGuckLive> is it a XY UV
[14:02:50] <uw> hi IchGuckLive
[14:02:51] <IchGuckLive> so Foam=1
[14:03:02] <uw> Deejay, hi to you as well
[14:03:07] <uw> and Loetmichel
[14:03:19] <uw> i'm still subscribed to your youtube channel
[14:03:49] <IchGuckLive> ;-) B)
[14:05:20] <IchGuckLive> marmite_: ? did you get the second file
[14:06:24] <marmite_> checking it right now
[14:06:48] <marmite_> awsome ! great to have :)
[14:06:51] <marmite_> really apriciate it
[14:18:49] <IchGuckLive> Ok im off for today BYE and keep your fingers crossed for Germany tioight Soccer final in ri o
[14:19:07] <XXCoder2> ill do it for usa if usa still in lol
[14:21:12] <anarchos> is there such a thing as a 3d printer converter to turn a mill into a 3d printer?
[14:21:26] <ReadError> I think ever since I told IchGuck that its bye not 'by' he put a replace in
[14:21:26] <anarchos> i was thinking a print head in an r8 spindle might work
[14:21:35] <ReadError> since he always says BYE now ;O
[14:22:28] <cncformywife> Hi all :-)
[14:23:30] <XXCoder2> hey
[14:25:19] <cncformywife> what i can do with dremel based cnc?
[14:25:31] <XXCoder2> make parts for better cnc
[14:25:37] <XXCoder2> artwork, etching
[14:25:45] <Loetmichel> cncformywife: not muc
[14:25:47] <Loetmichel> h
[14:25:54] <Loetmichel> ise a proxxon IB/e at least
[14:26:10] <Loetmichel> much better spindle bearings than dremel
[14:26:15] <archivist> dremel has loose bearing mountings
[14:26:26] <XXCoder2> honestly bosch trim router is only like 30 bucks more than dermel and much better
[14:26:28] <cncformywife> what is "proxxon IB"
[14:26:43] <archivist> other junk
[14:26:44] <cncformywife> i have a dremel 4000
[14:26:49] <Loetmichel> XXCoder2: the router is roughly 10 times the weight
[14:27:01] <Loetmichel> and roughly 3 times the size of a dremel/proxxon
[14:27:02] <XXCoder2> youre talking about full size router
[14:27:22] <Loetmichel> cncformywife: the one on this machine:
[14:27:42] <Loetmichel> https://www.youtube.com/watch?v=uYgyqjHCBLg
[14:27:44] <cncformywife> i cut bolts with the dermel.
[14:28:03] <Loetmichel> the dremel has bad bearings. its no good for side forces on the shaft
[14:28:48] <Loetmichel> and its called proxxon IB/e
[14:29:05] <Loetmichel> the one from proxxon wiht the aluminium head
[14:29:12] <cncformywife> but it's not even screch the surface ...
[14:29:30] <Loetmichel> the other proxxon "dremel alikes" have a plastic shell, not as good as the IB/e
[14:29:57] <cncformywife> what about stainless?
[14:29:58] <Loetmichel> cncformywife: the video was a demo for the movement speed of the machine, not for the proxxon-
[14:30:05] <Loetmichel> it just happens to be on this machine
[14:30:38] <Loetmichel> milling steel with a dremel/proxxon isnt best
[14:30:49] <Loetmichel> sounds BAD and is not really precise
[14:31:03] <cncformywife> and how it's move soooo fast?
[14:31:15] <Loetmichel> https://www.youtube.com/watch?v=FGNbgkg9O2Y
[14:31:38] <Loetmichel> cncformywife: because that likke beast has no leadscrews but uses a steel cable drive
[14:31:48] <Loetmichel> s/likke/little
[14:32:44] <cncformywife> work 90 deg? on the side?
[14:33:32] <kfoltman> cncformywife: I use proxxon (newer model, ibs/e)
[14:33:45] <kfoltman> cncformywife: it's not ideal, but far better than dremel (which I also have)
[14:33:51] <XXCoder2> so dirty. lol https://www.youtube.com/watch?v=QNLjMg0Nitk
[14:34:23] <kfoltman> Loetmichel: what material was cut in that video?
[14:34:36] <Loetmichel> zinc plated steel
[14:34:36] <Jymmm> Pocket CNC Controller display... http://www.adafruit.com/products/938
[14:34:40] <Loetmichel> 1mm
[14:34:41] <cncformywife> XXCoder2: i'm soo like this style of machine. but they so expensive :(
[14:34:47] <kfoltman> Loetmichel: 10 passes?
[14:34:50] <Loetmichel> right
[14:34:55] <XXCoder2> cnc yeah
[14:35:11] <kfoltman> Loetmichel: would it cut 2mm in 20 passes? or is it non-linear?
[14:35:23] <XXCoder2> if you had that machine you probably could make very good cnc, but if you has it, why would you need another ;)
[14:35:47] <Loetmichel> XXCoder2: result: http://www.cyrom.org/palbum/main.php?g2_itemId=13888
[14:35:59] <XXCoder2> snow!!!
[14:36:03] <kfoltman> Loetmichel: hahahaha
[14:36:09] <Loetmichel> ... after some vacuumimg: http://www.cyrom.org/palbum/main.php?g2_itemId=13891
[14:36:17] <Loetmichel> kfoltman: it is linear
[14:36:25] <XXCoder2> lol
[14:36:43] <kfoltman> "and this, kids, is why you invest in good dust removal system before taking on serious jobs"
[14:37:06] <cncformywife> for 5000$ what is the best machine?
[14:37:11] <kfoltman> the end result looks good though
[14:37:22] <Loetmichel> kfoltman: was for the company
[14:37:29] <archivist> there is no "best machine"
[14:37:40] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13567
[14:37:43] <cncformywife> for steel
[14:37:53] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12843
[14:37:53] <cncformywife> i mean after conversion..
[14:37:55] <XXCoder2> used cnc machine from ebay
[14:37:56] <archivist> but there are good machines for particular jobs
[14:37:59] <kfoltman> are there even $5000 machines capable of cutting steel?
[14:38:06] <XXCoder2> kfoltman: easily
[14:38:13] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=10877
[14:38:13] <XXCoder2> thgere is cnc plans to build one for 3k
[14:38:17] <cncformywife> i see the G0704
[14:38:18] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=10874
[14:38:22] <XXCoder2> extremely strong 8020 based design
[14:38:42] <Loetmichel> its an double usb port that can folded in, for a pc that has a fron door
[14:38:51] <Loetmichel> so you dont break the thumbdrives
[14:38:52] <XXCoder2> not bad
[14:39:38] <kfoltman> Loetmichel: anyway, I'm intrigued by the proof of a proxxon milling steel (even at 0.1mm passes) with decent results :) my table rebuild is already underway, to make it less saggy
[14:40:02] <kfoltman> Loetmichel: did you have to replace all the bearings afterwards? ;-)
[14:40:06] <Loetmichel> kfoltman: you did hear the screeching, tough?
[14:40:23] <Loetmichel> i dont think that bearing will survive very long... ;-)
[14:40:32] <kfoltman> Loetmichel: yeah, terrible
[14:40:50] <kfoltman> OMG
[14:40:52] <kfoltman> 0:30
[14:40:55] <Loetmichel> i used that proxxon beacuse the mill wasnt meant to do horiziontal
[14:41:08] <Loetmichel> and the chinese HF spindle is to thick
[14:41:14] <kfoltman> Loetmichel: the 800W water-cooled spindle, is that more capable?
[14:41:20] <Loetmichel> a LOT more
[14:41:27] <Loetmichel> but it doesent fit under the beam
[14:41:34] <Loetmichel> so i "tricked" a bit
[14:41:45] <cncformywife> http://i.imgur.com/1BVqmf0.jpg
[14:41:48] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14483
[14:41:59] <cncformywife> what do you think on my design?^^
[14:42:00] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14486
[14:42:04] <Loetmichel> you see the difference?
[14:42:33] <archivist> cncformywife, I dont like those bar supports
[14:42:33] <XXCoder2> interesting
[14:42:35] <Loetmichel> i had to mill some plugs in the side of that boxes
[14:42:41] <kfoltman> Loetmichel: horizontal vs vertical, what else?
[14:42:44] <XXCoder2> why would you need that alternate mode?
[14:42:58] <kfoltman> Loetmichel: and yes, the Chinese one wouldn't fit
[14:43:05] <Loetmichel> normal vertical is the big 800W spindle, horizontal the proxxon
[14:43:14] <archivist> you need fully supported bars like Loetmichel has
[14:43:15] <kfoltman> not enough clearance for the 80mm+ spindle
[14:43:23] <Loetmichel> right
[14:43:35] <kfoltman> archivist: I have fully supported rails on every axis
[14:43:37] <cncformywife> what is the problem?
[14:43:46] <Loetmichel> luckily it was just a 50 pcs run ;-)
[14:43:49] <archivist> bending
[14:43:49] <cncformywife> archivist: ^
[14:44:00] <kfoltman> archivist: (if that's what you're referring to)
[14:44:10] <kfoltman> archivist: only 12mm though
[14:44:23] <cncformywife> it is 12mm
[14:44:59] <archivist> cncformywife, that would be a spring and you will get a lot of vibration
[14:45:07] <kfoltman> Loetmichel: I would have a lot of uses for this sort of horizontal arrangement - same as you, i.e. holes for sockets in boxes
[14:45:29] <kfoltman> Loetmichel: or maybe even put it parallel to the ground
[14:45:45] <kfoltman> horizontal milling but in different axis, if possible
[14:45:50] <kfoltman> along the Y
[14:46:17] <kfoltman> might be simply a second set of holes in the Z axis
[14:46:34] <cncformywife> i have 3 stepper motors.. so i think to make a cnc from them.. in the cheapest way.. :)
[14:46:38] <Loetmichel> kfoltman: normally i make the holes PRIOR to bending the boxes
[14:46:56] <kfoltman> Loetmichel: hard to do that if I buy ready-made ABS boxes (-:
[14:47:09] <XXCoder2> cncformywife: http://hackaday.com/2014/07/11/400-diy-cnc-machine-is-surprisingly-simple/
[14:47:12] <kfoltman> if manufacturing from scratch, sure, that's better
[14:47:18] <Loetmichel> i just used a 50 run of old frames and converted them to a new design
[14:48:17] <kfoltman> makes a lot of sense
[14:48:33] <XXCoder2> kfoltman: makes sense
[14:48:55] <cncformywife> XXCoder2: my morors will be good for that?
[14:49:06] <XXCoder2> NEMA 23 right?
[14:49:37] <kfoltman> cncformywife: decent NEMA23 with good torque will be fine at that job
[14:49:49] <cncformywife> 80Ncm
[14:49:55] <kfoltman> I have many things to complain about, but not the motors
[14:50:03] <kfoltman> cncformywife: try 3Nm
[14:50:05] <kfoltman> :P
[14:50:15] <kfoltman> although 0.8Nm should still get you somewhere
[14:50:32] <cncformywife> i get tham free..
[14:50:47] <kfoltman> sounds good if you can upgrade them later
[14:50:48] <cncformywife> and i have 3 5A drivers..
[14:50:53] <cncformywife> all free.
[14:50:59] <kfoltman> what shaft, 8mm? 1/4"?
[14:51:10] <XXCoder2> my nema23 motors is 11Nm, but cannot picture what it means.
[14:51:19] <kfoltman> XXCoder2: 11???
[14:51:21] <kfoltman> sounds like a lot
[14:51:24] <cncformywife> i think to work with 5/16
[14:51:27] <cncformywife> 18 TPI
[14:51:41] <XXCoder2> lets see if I did conversion correctly but probably not
[14:52:18] <kfoltman> XXCoder2: all the oz*in, kg*m, N*m and various combinations are really annoying
[14:52:24] <XXCoder2> yepp lol 1.1Nm
[14:52:24] <kfoltman> makes it really hard to compare the motors
[14:52:58] <XXCoder2> divided by 10 not 100, olvious mistake when Cent means 100
[14:53:08] <kfoltman> XXCoder2: I'm probably not getting 3Nm out of my motors because of suboptimal power supply and cheap drivers, but still - last time I checked, I got 2000mm/min reliably
[14:53:25] <XXCoder2> 1.1Nm is fine?
[14:53:26] <cncformywife> any help?
[14:53:27] <kfoltman> no stalling/missed steps
[14:53:39] <kfoltman> cncformywife: 0.8Nm should be fine
[14:54:09] <kfoltman> cncformywife: just make sure that your couplers match your motors
[14:54:11] <cncformywife> fine for what type of machine?
[14:54:21] <kfoltman> cncformywife: a desktop, home one
[14:54:23] <XXCoder2> like the junk machine I linked ago a sec
[14:54:25] <kfoltman> "desktop"
[14:54:41] <kfoltman> mine would take up a whole desk :P
[14:54:51] <XXCoder2> well its desk sized
[14:54:56] <cncformywife> for my deremel?
[14:54:57] <XXCoder2> lol
[14:55:13] <XXCoder2> my plan orginially was to use dermel
[14:55:19] <kfoltman> cncformywife: forget dremel, get a proxxon ib/e or ibs/e or some serious router
[14:55:19] <XXCoder2> but realized how shitty it is
[14:55:25] <XXCoder2> so trim router it is lol
[14:55:41] <XXCoder2> mine has rpm range 8k to 16k so good range
[14:55:41] <cncformywife> deremel q proxxon
[14:56:02] <kfoltman> cncformywife: dremel can't take the type of loads you get during milling, will lose RPMs quickly too
[14:56:17] <kfoltman> it will be loud and weak
[14:56:19] <kfoltman> and die quickly
[14:56:23] <kfoltman> even worse
[14:56:25] <kfoltman> it's hard to mount
[14:56:37] <Jymmm> Dremel is EASY to mount
[14:56:52] <XXCoder2> yeah trim router has this very nice sleeve thats round and easy to mount
[14:56:53] <kfoltman> proxxon has a collar which you can mount in SK20 block, and it stays there
[14:57:17] <kfoltman> the block itself is a standard part so it's not very expensive
[14:57:43] <kfoltman> I've previously used dremel and an aluminium tape, but it wasn't reliable
[14:58:30] <cncformywife> http://i01.i.aliimg.com/wsphoto/v2/520900853_1/12V-Small-PCB-Drill-Mini-Press-Drilling-with-0-8mm-Drill-090053.jpg
[14:58:34] <cncformywife> look nice!!
[14:58:53] <kfoltman> cncformywife: yeah maybe for drilling small holes in phenolic PCBs :P
[14:59:30] <cncformywife> and for plastic?
[14:59:45] <kfoltman> maybe
[14:59:50] <kfoltman> depends on plastic I suppose
[14:59:57] <cncformywife> on wood?
[15:00:04] <kfoltman> I really wouldn't do that
[15:00:27] <cncformywife> i want small and acurate machine.
[15:00:31] <kfoltman> get proxxon :)
[15:00:52] <kfoltman> extra bonus: low runout, so you can use *really* small drills :)
[15:00:59] <kfoltman> or endmills
[15:01:11] <XXCoder2> is there professal type spidles smaller than dermel lol
[15:01:23] <kfoltman> XXCoder2: haven't seen one
[15:01:45] <kfoltman> the smaller I've seen (in a picture) was a 300W Chinese spindle, but people say it's crap, very underpowered
[15:02:11] <XXCoder2> whoa
[15:02:18] <XXCoder2> no computer glue gun http://danieldebruin.tumblr.com/tnt
[15:02:26] <cncformywife> http://www.rolanddga.com/products/milling/
[15:02:30] <kfoltman> cncformywife: you can use your dremel for initial testing
[15:02:32] <XXCoder2> barely any electrics it seems
[15:03:01] <XXCoder2> rather, NO electrics
[15:03:09] <cncformywife> i have the brake out board and 3 drivers..
[15:03:42] <cncformywife> kfoltman: you see the machines in the link?
[15:04:22] <cncformywife> they small and very precise and you can mill any material.
[15:04:35] <kfoltman> heh
[15:04:40] <kfoltman> 21000 USD
[15:04:55] <kfoltman> 400W spindle, 4x dremel?
[15:05:57] <kfoltman> the cheapest one is $8000
[15:06:23] <kfoltman> Feed rate XY-axis: 0.0039 to 1.9 in./s (0.1 to 50 mm/sec.),
[15:06:51] <kfoltman> Spindle motor Brushless DC motor, Maximum 100 W
[15:07:08] <XXCoder2> amazing machine
[15:07:26] <XXCoder2> I can't imange the precision needed to build such a machine. no computer, no electricity!
[15:07:29] <kfoltman> Acceptable materials Resins such as chemical wood and modeling wax (metal not supported)
[15:07:34] <XXCoder2> clockwork 3d printer.
[15:07:53] <kfoltman> XXCoder2: it's impressive, but pretty limited in shapes that can be obtained
[15:08:08] <cncformywife> how i can make machine like that?
[15:08:27] <XXCoder2> kfoltman: and limited to chemical cure stuff only too
[15:08:32] <XXCoder2> it cant melt anything
[15:08:41] <kfoltman> cncformywife: so, $8000 gives you the amount of power comparable with dremel or proxxon, feed rate slightly above one of my pathetic contraption, and won't mill any metal
[15:08:47] <Jymmm> Thats what glue guns are for.
[15:08:47] <XXCoder2> wonder if it would work with epoxy lol
[15:10:03] <kfoltman> cncformywife: the 21k USD machine won't mill steel either, only non-ferrous metals
[15:11:10] <cncformywife> kfoltman: http://www.rolanddga.com/products/milling/dwx4/
[15:11:33] <kfoltman> "Mills wax, zirconia, PMMA and composite resins"
[15:13:11] <cncformywife> zirconia vs steel...
[15:13:13] <cncformywife> mmm
[15:13:13] <XXCoder2> check out other projects by guy who made clockwork 3d printer. amazing stuff
[15:13:57] <cncformywife> the mechanical 3d printer ?
[15:14:02] <XXCoder2> yeah
[15:15:28] <cncformywife> http://www.rolanddga.com/products/milling/mdx540/
[15:15:35] <cncformywife> LOVE!
[15:17:02] * kfoltman wouldn't mind a 4th axis ;)
[15:17:22] <XXCoder2> 9 axis ;)
[15:17:23] <archivist> 4 is not enough
[15:17:39] <kfoltman> XXCoder2: there are wire bender machines with 20 axes or so
[15:17:56] <kfoltman> archivist: it's not, but it's an improvement ;)
[15:18:02] <XXCoder2> kf yeah
[15:18:03] <XXCoder2> https://www.youtube.com/watch?v=MwZCuTlSKeY
[15:18:09] <XXCoder2> I want it :(
[15:18:46] <cncformywife> I want it tooo
[15:19:00] <cncformywife> i need to be rich !
[15:19:10] <cncformywife> to make my wife happy!
[15:19:32] <Jymmm> Uh, no comment.
[15:19:50] <XXCoder2> lathe is simplest for that ;)
[15:19:55] <kfoltman> hahaha
[15:20:01] <Jymmm> I lie... I'd kick the bitch to the curb!
[15:20:11] <cncformywife> cnc with dimond cutter VS jast dimond..
[15:20:29] <kfoltman> any DIY solutions for tool changers? :D
[15:20:44] <XXCoder2> I saw system at old cnc at work
[15:20:52] <XXCoder2> its just row of holders on side
[15:21:12] <cncformywife> kfoltman: give my CNC i will change tools for free.
[15:21:14] <XXCoder2> your Y have to be wider than work area so it can get out of work area to pick up and drop tools
[15:21:28] <kfoltman> right, but you still need the 'clip on' mechanism to attach tools
[15:21:38] <XXCoder2> indeed
[15:21:44] <kfoltman> as opposed to fiddling with the chuck
[15:22:44] <XXCoder2> well
[15:22:52] <XXCoder2> sounds like you need 2 parts
[15:23:34] <XXCoder2> one to hold it, and another to prevent it from being rotated (whole whin spins but bit assemly itself should not have its own rotation in respect of machine spin)
[15:24:10] <XXCoder2> machines at work has holder part that has ball on top and slots on bottom. it grips ball and clips is where it prevents rpotation
[15:24:11] <kfoltman> a solenoid to push on the tool lock on the proxxon? (-:
[15:24:42] <cncformywife> what about clips like SDS?
[15:25:02] <kfoltman> oh https://www.youtube.com/watch?v=Z9SeNxk8TgY
[15:28:09] <XXCoder2> kf thats similiar system as ones at work
[15:28:35] <XXCoder2> https://www.youtube.com/watch?v=AgJn00UMOPA
[15:29:28] <XXCoder2> lol http://danieldebruin.tumblr.com/luxa
[15:39:03] <tk84916> Hello, I'm working with mesa equipment (5i23 and 7i49), A-M-C drives set as open controllers (only command signal into drives). Through tuining I am finding that I only have large ferrors (~.150, mferror at ~.250). I believe through the poking around the inverse deadband component located here (http://wiki.linuxcnc.org/cgi-bin/wiki.pl?ContributedComponents#Other_Components) is needed to help to minimize the ferror. Looking for mor
[15:41:44] <kfoltman> XXCoder2: the thing makes a weird "pssss" kind of sound when moving the Z axis and changing the tool, any idea what it can be? some pneumatic system?
[15:42:13] <XXCoder2> I think it does use pneumatic system to grip the bit assembly
[15:43:33] <XXCoder2> I cant make an definitive answer because I cant hear that sound lol
[15:44:09] <kfoltman> yeah that might be a bit of a problem
[15:44:21] <XXCoder2> well
[15:44:28] <XXCoder2> it looks to be very similiar
[15:44:45] <XXCoder2> only difference is work shop ones has even bigger ball onj top
[15:50:47] <kfoltman> Loetmichel: how often do you have to change collets in proxxon?
[15:50:56] <Loetmichel> never
[15:51:08] <Loetmichel> the proxxon collets are hardened steel
[15:51:16] <Loetmichel> not aluminium as the dremel ones
[15:51:28] <Loetmichel> ... and three-slot, not 4 slot
[15:51:54] <kfoltman> my 3.2mm collet lets the tools "sink", not sure if it's just because of layer depth (= excessive force pushing the bit in) or is there something wrong with it
[15:52:38] <kfoltman> in some cases (after some jobs), I can simply move the tool in the collet by bare hands, not even forcing it
[15:53:03] <kfoltman> maybe I'm doing something stupid :)
[15:53:23] <XXCoder1> dunno but maybe its not locking properly
[15:53:39] <kfoltman> well, it is locked before the job, and then it... unlocks
[15:54:13] <kfoltman> I think it happens more often on speeds > 10000rpm
[15:54:22] <kfoltman> vibration or something?
[15:54:41] <XXCoder1> maybe or its somehow toqred
[15:54:43] <XXCoder1> torqued
[15:54:56] <kfoltman> I ruined a couple bits this way
[15:54:58] <XXCoder1> would be funny if it was swarf hitting it lol
[15:55:12] <kfoltman> probably not the case :D
[16:02:45] <Loetmichel> kfoltman: tighten the collet chuck better
[16:06:37] <Einar1> It could also be the collet is bellmouthed. Or the collet holder does not have the right cone angle, in which case every collet will be bellmouthed.
[16:09:36] <Einar1> I complained about my 2.2Kw spindle being way out of spec (runout). First I measured it to be very good, then I tried another collet and it was 0.06mm out.
[16:12:00] <Einar1> Then back to the first collet and bit, and now that was also way out of spec. What is happening? Then I measured the tapered cone in the spindle shaft and it was out by 0.03-0.05mm at the front and at the inner end of the taper. Also it was very rough ground. So it will grip the collet differently each time.
[16:13:27] <Einar1> The seller said this was a drop in quality all over China. Actually I believe him, but told him he should not state a runout that is 10 times better than what we get!
[16:14:15] <kfoltman> Loetmichel: just finished my table upgrade
[16:14:26] <kfoltman> want a pic? vomit trigger alert...
[16:16:32] <Einar1> He said he will have a new spindle shaft made to spec and send me. We'll see if it shows up. If so, we know at least one seller of these spindles that can be used. He said he could do this in the future for
[16:16:58] <Einar1> a price increase of $130 if I remember the message correct.
[16:17:23] <Einar1> Anyone else that actually measured the runout of their China spindle?
[16:25:44] <Jymmm> WOW, this is pretty good... https://www.youtube.com/watch?v=h8l2fTZeJJI
[16:33:11] <Loetmichel> kfoltman: i have a strong stomach
[16:33:16] <Loetmichel> pic please ;)
[16:34:03] <XXCoder1> Jymmm thanks
[16:34:17] <Jymmm> ?
[16:34:18] <cncformywife> someone know about CNC simulator?
[16:34:27] <XXCoder1> cnc yeah
[16:34:36] <XXCoder1> I use it a little. pretty cool
[16:34:39] <Jymmm> XXCoder1: ???
[16:34:49] <cncformywife> ???
[16:34:57] <cncformywife> and....
[16:35:08] <XXCoder1> not much else lol didnt use it much yet
[16:36:45] <XXCoder1> Jymmm: was thinking you for great video
[16:37:16] <cncformywife> XXCoder1: link? name? info? bone?
[16:37:19] <Jymmm> XXCoder1: Ah, gotcha. YW
[16:37:45] <XXCoder1> cncformywife: http://cncsimulator.info/
[16:38:26] <cncformywife> XXCoder1: it's free?
[16:38:31] <XXCoder1> kind of
[16:38:44] <XXCoder1> you have to "refill" it once per few months but costs nothing
[16:38:57] <XXCoder1> you have to pay if you don't want to, but its really not annoying.
[16:40:09] <cncformywife> what do you mean?
[16:40:18] <XXCoder1> you get an email
[16:40:34] <Nebukadneza> mh, say -- is there a good gcode simulator that can preview 4-axis (i.e., hotwire-)cutting?
[16:40:39] <XXCoder1> you click it, website provides you with "petrol code" which enables cncsimiliator to run for another 3 months
[16:40:41] <Loetmichel> hmm, opinions? better use the red switches to "move" the buttons from tha back to the front or the black ones? -> http://www.cyrom.org/palbum/main.php?g2_itemId=15026
[16:41:38] <XXCoder1> gonna mow yard, laters
[16:43:34] <cncformywife> so it is free?
[16:56:10] <cncformywife> what is this thing?
[16:56:11] <cncformywife> http://www.cyrom.org/palbum/main.php?g2_itemId=10534
[16:57:30] <Loetmichel> cncformywife: inside of the mill you've seen in the vid a few hours earilier
[16:58:02] <cncformywife> with the proxxon?
[16:58:07] <Loetmichel> yes

[17:04:51] <kfoltman> Loetmichel: imgur.com/tmbQIFx.jpg not much light in my room alas
[17:05:16] <Loetmichel> hmm
[17:05:29] <Loetmichel> still MDF?
[17:05:34] <kfoltman> 18mm
[17:05:40] <kfoltman> mounted on top of existing 12mm MDF table
[17:05:54] <kfoltman> but it's not bent :)
[17:06:01] <cncformywife> what cad program you guys using?
[17:06:10] <kfoltman> cncformywife: draftsight
[17:06:23] <Loetmichel> <- corel draw 8 ;-)
[17:06:39] <kfoltman> o.O
[17:06:52] <cncformywife> so.. no 3d programs?
[17:07:10] <kfoltman> Loetmichel: I tried to seal it with carpenters glue, but I don't think it helped
[17:07:30] <Loetmichel> kfoltman: espcially when carpenters glue is water soluble
[17:07:37] <kfoltman> it is
[17:07:57] <kfoltman> will probably need to put proper sealant instead
[17:08:02] <cncformywife> kfoltman: too dark pic!
[17:08:07] <kfoltman> cncformywife: I know
[17:08:08] <cncformywife> use flash
[17:08:17] <kfoltman> it's my phone :|
[17:08:35] <kfoltman> I won't borrow wife's DSLR just to make a quick snapshot
[17:08:46] <kfoltman> less trouble to just make a better pic tomorrow in daylight :)
[17:09:01] <cncformywife> you also but the CNC for her..
[17:10:02] <cncformywife> what is the problem with the machine?
[17:10:36] <kfoltman> cncformywife: mostly, teething problems
[17:10:57] <kfoltman> up to now the table was bent so I couldn't do any engraving type tasks
[17:11:07] <cncformywife> teething??
[17:11:17] <kfoltman> as in, problems due to "not done properly yet"
[17:11:28] <kfoltman> I'm a beginner at this
[17:11:31] <XXCoder1> whew
[17:11:35] <cncformywife> me to..
[17:11:40] <XXCoder1> bit cloudy but hella lot humidity and heat
[17:12:34] <cncformywife> kfoltman: how the table get bent?
[17:12:49] <cncformywife> water?
[17:12:50] <XXCoder1> yeah how
[17:13:18] <kfoltman> cncformywife: not enough rigidity + ballscrew/rail connection sucks
[17:13:41] <kfoltman> the table practically sits on the carriage blocks for linear rails
[17:13:54] <kfoltman> but the ballscrew (for legacy reasons, let's say) is a few cm away
[17:14:06] <cncformywife> we need thamspeak server..
[17:14:49] <cncformywife> you can take a pic from the side?
[17:15:10] <kfoltman> you won't see anything, because the rail and the table is in the way
[17:15:45] <cncformywife> you build by any instractions?
[17:15:47] <kfoltman> I'll make a better pic tomorrow in daylight, so you'll be able to see the dodginess of the ballscrew mount in its full glory ;)
[17:16:05] <cncformywife> flash light...
[17:16:13] <kfoltman> still not enough light
[17:16:44] <kfoltman> I improvised the whole thing based on available materials/tools, so some parts are really bad
[17:17:50] <cncformywife> fire some magnesium for sec..
[17:18:18] <cncformywife> it is your design?
[17:18:26] <cncformywife> kfoltman: ^
[17:18:34] <XXCoder1> kfoltman: use your cnc to make better parts for it
[17:19:46] <cncformywife> rule num 1! first pull cnc out of my ass
[17:20:21] <cncformywife> rule num 2! make a cnc machine with your cnc machine.
[17:21:12] <cncformywife> kfoltman: ^
[17:21:22] <cncformywife> XXCoder1: ^
[17:21:54] <XXCoder1> actually once you have a crude cnc machone thats accurate enough
[17:22:00] <XXCoder1> you can build better machine with it.
[17:22:19] <XXCoder1> or upgrade parts
[17:22:24] <cncformywife> but you cant make same size..
[17:22:28] <cncformywife> only smaller..
[17:22:32] <XXCoder1> sure you can
[17:22:33] <Loetmichel> cncformywife: when you look at the sorry excuse for a cnc i have started with... http://www.cyrom.org/palbum/main.php?g2_itemId=2859
[17:23:17] <Loetmichel> ... much better now ;-) -> http://www.cyrom.org/palbum/main.php?g2_itemId=14040
[17:23:20] <cncformywife> and how you make the parts for it??
[17:23:28] <Loetmichel> on a friends CNC mill
[17:23:41] <Loetmichel> that was a engraver i modified to be a cnc mill
[17:23:46] <Loetmichel> 20 years ago
[17:23:47] <cncformywife> hehe LOL
[17:23:48] <cncformywife> <cncformywife> rule num 1! first pull cnc out of my ass
[17:23:50] <XXCoder1> most of parts is small enough. only few are not. You make large parts manually
[17:24:29] <cncformywife> but we dont have a friend with cnc!!
[17:24:38] <XXCoder1> you make your first cnc yourself
[17:24:48] <XXCoder1> I am building entire cnc machine manually
[17:25:42] <cncformywife> in my design i hope i can make it with only jigsaw..
[17:25:53] <cncformywife> this is all i have...
[17:25:58] <XXCoder1> I have tabl saw and drill press
[17:26:15] <cncformywife> you in NY?
[17:26:48] <cncformywife> XXCoder1: ^?
[17:27:17] <XXCoder1> me? sure. just 2,870 miles west
[17:27:34] <cncformywife> hehe..!
[17:27:43] <cncformywife> cool nice.
[17:27:48] <XXCoder1> heh
[17:28:02] <XXCoder1> went to interview at maryland twice and nj once
[17:28:10] <XXCoder1> didnt get job lol
[17:28:13] <kfoltman> cncformywife: well, 'my design' is a bit of overstatement, given that I borrowed ideas from everywhere
[17:28:25] <kfoltman> cncformywife: the frame is based on solsylva 13x13" machine
[17:28:51] <cncformywife> kfoltman: you see the rendering?
[17:28:52] <XXCoder1> mines bit more custom, meaning crapper
[17:29:11] <kfoltman> which rendering?
[17:29:11] <cncformywife> this > http://i.imgur.com/1BVqmf0.jpg
[17:29:24] <cncformywife> i make it
[17:29:56] <XXCoder1> cnc you can get mount block from amazon ebay or aliexpress cheap
[17:29:57] <kfoltman> cncformywife: ohnoez unsupported rails
[17:30:02] <Loetmichel> cncformywife: swirtch to SBR
[17:30:04] <XXCoder1> MUCH more rigid for motors
[17:30:12] <Loetmichel> unsopported is bullshit
[17:30:20] <kfoltman> unsupported bends like mad
[17:30:36] <XXCoder1> unsupported is fine if larger diameter?
[17:30:39] <XXCoder1> like 30mm
[17:30:47] <kfoltman> especially if it has to withstand the load of large gantry / spindle
[17:30:50] <Loetmichel> XXCoder1: depends on travel
[17:31:06] <Loetmichel> 30mm would be ok for 300mm travel, not more
[17:31:08] <XXCoder1> Loetmichel: assume cnc's machine since it really is his design ;)
[17:31:37] <kfoltman> I'm sure there are calculators for deflection of an unsupported rod ;)
[17:31:44] <cncformywife> kfoltman: ^
[17:31:46] <XXCoder1> m sure too
[17:32:14] <kfoltman> anyway, nice rendering, but I wouldn't want that machine ;)
[17:32:22] <Loetmichel> i had one with 25mm unsupported and 1000mm*600mm travel...: you could pull the mill bit about 2mm with less than 10kg force
[17:32:30] <XXCoder1> mines https://scontent-a-sea.xx.fbcdn.net/hphotos-xpf1/t1.0-9/s720x720/10427235_456337351177840_1505210135140562994_n.png
[17:32:37] <XXCoder1> still figuring lots stuff
[17:32:44] <kfoltman> Loetmichel: heh
[17:32:56] <XXCoder1> notice there is no motors yet and Z axis is impossible to place due to no room for motor
[17:33:04] <kfoltman> Loetmichel: I realized that my rails are not screwed to the base properly
[17:33:09] <kfoltman> only a few screws
[17:33:13] <Loetmichel> thats bad
[17:33:17] <kfoltman> so, plenty of deflection there as well
[17:33:22] <Loetmichel> use every aviable hole in the rails!
[17:33:29] <cncformywife> XXCoder1: what is the program that you use??
[17:33:42] <XXCoder1> freecad
[17:33:53] <XXCoder1> I couldnt hack sketchup
[17:33:57] <kfoltman> Loetmichel: I'll need an angular drill ;)
[17:34:03] <cncformywife> it is look like crap!
[17:34:09] <XXCoder1> Loetmichel: that sounds dirty
[17:34:16] <cncformywife> use solidworks 2010!
[17:34:23] <XXCoder1> cncformywife: money?
[17:34:29] <kfoltman> solidworks 2010, doesn't sound cheap!
[17:34:31] <Loetmichel> XXCoder1: that may be only in you r mind...
[17:34:32] <cncformywife> torrent :)
[17:34:46] <kfoltman> we're nice people, we don't warez :P
[17:34:50] <XXCoder1> indeed
[17:35:06] <XXCoder1> besides
[17:35:07] <cncformywife> what HW you have?
[17:35:13] <XXCoder1> as long as its understandable its fine
[17:35:23] <kfoltman> though, I'm still on evaluation copy of cambam :S
[17:35:33] <XXCoder1> cambam dunno
[17:35:39] <XXCoder1> I do need to figure that out
[17:35:52] <XXCoder1> 500 line limit past 30 uses right? right
[17:35:58] <Loetmichel> i use coreldraw and BoCNC.... althogh i have a legal copy of tubocad 3d 17
[17:36:16] <Loetmichel> but i cant work with it... very slow learning curve ;-)
[17:36:18] <cncformywife> onesec
[17:36:22] <XXCoder1> wish I could use inkscape
[17:36:26] <XXCoder1> I love it
[17:36:33] <kfoltman> XXCoder1: uh, you can
[17:36:39] <kfoltman> then import to cambam or something
[17:36:46] <XXCoder1> how? no import
[17:36:48] <XXCoder1> oh?
[17:36:51] <kfoltman> svg?
[17:36:57] <XXCoder1> yeah
[17:37:05] <kfoltman> there are some free cam tools that can do svg->gcode too I think
[17:37:11] <kfoltman> they're just annoying
[17:37:13] <XXCoder1> hmm ok
[17:37:23] <kfoltman> cambam is annoying too, just a little bit less
[17:38:20] <XXCoder1> lol ok
[17:42:39] <cncformywife> XXCoder1: PM ^
[17:42:57] <XXCoder1> cncformywife: I said no.
[17:43:05] <XXCoder1> repeat to be added to my ignore list
[17:43:17] <XXCoder1> Okay fine ignored
[17:43:25] <cncformywife> ok....
[17:47:50] <cncformywife> ?
[17:48:27] <cncformywife> i to help..
[17:48:40] <cncformywife> i try to help*
[17:49:14] <cncformywife> XXCoder1: ?
[17:49:57] <cncformywife> kfoltman: ?
[17:50:11] <cncformywife> Loetmichel: ?
[17:50:54] <cncformywife> jdh: ?
[17:51:16] <cncformywife> :-(
[17:51:33] <cncformywife> Someone?
[17:53:56] <cncformywife> you block me or something?
[17:54:04] <cncformywife> Hello??
[17:54:57] <Loetmichel> hmm?
[17:56:19] <cncformywife> Loetmichel: hi
[17:57:00] <cncformywife> i type.. but nobody answer..
[17:57:50] <Loetmichel> because they put you on their ignore list for distributing warez( i assume)
[17:58:07] <cncformywife> why??
[17:58:26] <cncformywife> i try to help them..
[17:59:05] <cncformywife> you can tell tham to unblock me?
[17:59:23] <Loetmichel> no
[17:59:30] <Loetmichel> i have no authority here
[17:59:40] <Loetmichel> its their decision
[18:00:14] <Loetmichel> and if someone tries to send copyrighted software to me i would do the same
[18:00:23] <cncformywife> but i cant talk to tham.. and explain...
[18:00:59] <Loetmichel> to late i would assume
[18:01:30] <cncformywife> so how i can learn stuff.. and fine a job?
[18:01:54] <Loetmichel> no idea
[18:03:05] <cncformywife> so.. how they can unblock me?
[18:04:58] <cncformywife> we are personal..
[18:06:08] <cncformywife> and he can work in student mode - the student version is free.
[18:08:21] <cncformywife> ok i will dont do it again !
[18:08:52] <cncformywife> you can tell them what i say..
[18:08:58] <cncformywife> ok i will dont do it again !
[18:12:36] <cncformywife> The_Ball: hi
[18:17:10] <noob2> morning
[18:20:51] <noob2> hello?
[18:24:14] <anarchos_> booyeah, installed dd-wrt on a router i got at the thirft shop, configured it as a wifi bridge and now have my no-wireless card LinuxCNC box connected to the internet :D
[18:26:03] <cnc4mywife> pleas unblock me
[18:26:21] <Tom_itx> dude give it a rest
[18:26:47] <cnc4mywife> i dont ti anything wrong.
[18:27:40] <cnc4mywife> please.. i try to help XXCoder1 to make better 3D models.
[18:27:41] <Tom_itx> anarchos_ have you used dd-wrt before?
[18:28:17] <cnc4mywife> anarchos_: please unblock me.
[18:29:07] <cnc4mywife> Tom_itx: you can retransfer my message..
[18:29:25] <Tom_itx> there are logs if anyone want's to hear you
[18:29:39] <Tom_itx> if they blocked you it was their choice to make
[18:30:08] <cnc4mywife> nobody read the logs..
[18:30:48] <cnc4mywife> but the block me without a way that i can explain thing..
[18:31:59] <anarchos> Tom_itx: not really, i installed it about a year ago and then said "cool it works" and shoved the router in a closet since i had no use for it at the time
[18:32:43] <anarchos> so the first part of the above sentence and last part were seperated by about a year :P
[18:35:17] <The_Ball> cnc4mywife, hi
[18:35:28] <cnc4mywife> hi
[18:35:55] <The_Ball> that's an interesting nick, can you numerically control your wife?
[18:36:53] <cnc4mywife> anarchos: thanks for un blocking me.
[18:37:48] <anarchos> it wasn't me, i don't have that sort of powers :P
[18:38:17] <cnc4mywife> The_Ball: no, she make jewelries and she want a CNC machine. so now is my problem :-)
[18:38:51] <cnc4mywife> anarchos: i mean to remove me from the personal ignore list..
[18:39:03] <The_Ball> aha, not a bad problem to have
[18:39:25] <cnc4mywife> yes..
[18:39:45] <cnc4mywife> i get 3 motors and 3 drivers from someone..
[18:40:27] <cnc4mywife> every motor is a stepper motor with 80Ncm of power.
[18:44:39] <cnc4mywife> The_Ball: now i'm looking for a design that is easy to build with manual tools.
[18:47:06] <cnc4mywife> XXCoder1: Please remove the ignore.. i try to help you improv your skills thats all. not something bad..
[18:51:04] <humble_sea_bass> roofles
[18:55:28] <jdh> The_Ball: I thought he was trying to trade his wife for a cnc
[18:56:54] <cnc4mywife> it's not wife for cnc - it's cnc for my wife... it is a big difference
[18:57:15] <ssi> trading your wife for cnc sounds like a much better value
[18:57:28] <jdh> depends on the CNC... and the wife. jpegs?
[18:59:07] <cnc4mywife> you see the rendering.. the wife pic.. sorry. but my wife stay with me!
[19:00:13] <ssi> jdh: then you could use your new machine to get chicks
[19:01:09] <cnc4mywife> it's ok.. my better half is fine.
[19:01:16] <fenugrec> G83
[19:01:45] <cnc4mywife> fenugrec: ??
[19:02:13] <fenugrec> dirty joke, sorry guys. Couldn't resist.
[19:06:08] <cnc4mywife> hi i_tarzan
[19:17:34] <humble_sea_bass> who let borat into the channel
[19:18:28] <jdh> amusing anyway.
[19:18:36] <jdh> in an uber-geeky sort of way
[20:42:19] <anarchos> are tormach mills based on an off the shelf mill?
[22:10:24] <anarchos> I have a question about the touch off command on the default axis screen
[22:10:46] <anarchos> and kinda a general question about the regular way to set up
[22:12:15] <anarchos> do i generally have the top of the work piece at Z0.0
[22:12:30] <anarchos> then use negative Z co-ordinates to cut into the piece?
[22:13:10] <cradek> yes
[22:14:39] <anarchos> ok so then I'd jog my bit down to the top of my piece, and hit the touch off button to set that as 0.0, right?
[22:15:31] <cradek> yep
[22:15:43] <Tom_itx> that's how alot of ppl do it yes
[22:15:51] <anarchos> ok cool
[22:16:29] <Tom_itx> i tend to set my Z above the work and drop the model the same Z offset in the cad program
[22:18:49] <anarchos> i see in the "machine" menu there is an option for tool touch off to fixture or tool touch off to workpiece
[22:19:34] <Tom_itx> i touchoff to workpiece
[22:20:11] <anarchos> your gcode would have to take in account the size of your vice/fixture or whatever to take advantage of touch off to fixture, no?
[22:20:58] <Tom_itx> i've had discussions here about that and it seems i do it differently than others here
[22:21:47] <Tom_itx> or maybe it's just lost in translation
[22:22:29] <anarchos> workpiece seem to make sense to me
[22:22:40] <anarchos> unless fixture is taken to mean table in most cases?
[22:22:48] <anarchos> then using +Z coordinates
[22:23:18] <Tom_itx> i wouldn't advise using Z+ coordinates
[22:24:51] <anarchos> yeah
[22:28:01] <anarchos> so using the standard "linuxcnc" gcode that's loaded on startup, i home x, y, z, then type in "G0" then "Z-0.2" to move the Z down a bit
[22:28:17] <anarchos> but when i hit touch off for Z the tool piece pops back up to 0.0?
[22:28:50] <anarchos> and doesn't set the new Z0.0 at Z-0.2?
[22:28:59] <anarchos> am i not getting how that's suppost to work?
[22:29:59] <Tom_itx> i use fixture offsets in all my programs
[22:30:23] <Tom_itx> you would enter the z value in the G54 offset table
[22:32:09] <anarchos> oh i see so if i moved it down -0.2 i have to type that into the box when homing?
[22:32:15] <anarchos> s/homing/touching off
[22:32:32] <anarchos> i thought that meant what do you want to set the current position to
[22:33:23] <Tom_itx> no, just select the z axis and click on the G54 offset in the pulldown in axis
[22:33:53] <Tom_itx> it somewhat depends if you have a tool changer or set each tool as you go
[22:47:14] <anarchos> i'm confused, lol
[22:58:40] <Tom_itx> anarchos, have a look at this http://gnipsel.com/linuxcnc/g-code/index.html
[22:58:56] <Tom_itx> especially the tool touch off and fixture offsets
[23:13:44] <anarchos> is that site down, or is it just me?
[23:13:46] <anarchos> thanks, though
[23:14:04] <XXCoder1> loads fine
[23:14:12] <anarchos> i'm just as new to machining as i am to CNC so the learning curve is pretty high :P
[23:14:14] <XXCoder1> assuming you talking about tom ir;
[23:14:16] <XXCoder1> url
[23:14:21] <anarchos> yea
[23:14:42] <anarchos> weird, can load the google cache copy but not the real site
[23:15:28] <XXCoder1> odd
[23:15:36] <pcw_home> works for me
[23:29:33] <anarchos> i think it may be because my tool offset is set to 0?
[23:29:39] <anarchos> because i seem to be doing what the page says
[23:31:19] <tjtr33> CaptHindsight, know anything about LinMot linear motor actuators, up in Elkhorn Wi? http://www.linmot-usa.com/ ( Swiss company, US reps in WI)
[23:35:57] <CaptHindsight> tjtr33: good stuff, they are also a Rockwell partner http://www.linmot-usa.com/events/ in the area July 30-31st
[23:36:44] <tjtr33> thx! think i go se 'em tomorrow
[23:37:45] <tjtr33> i bought this yaskawa 'positioning' drive but its really step/dir ( wtf has that to do with 'positioning' other than a common unit of measure)
[23:38:28] <anarchos> 1) open linuxcnc splash gcode, toggle estop/power 2) home x,y,z (z is preset to 0.5). 3) issue G0 then Z0.25 (we'll pretent i'm using a 1/4 inch plate to engrave on, so 0.25 is top of my work). 4) hit touch off to Z, leave "enter z coordinate relative to work piece" as 0.0, leave co-ord system as P1 G54.
[23:38:42] <CaptHindsight> tjtr33: what range of force do you need? and what travel?
[23:38:43] <anarchos> and tool jumps down to original Z0, which would cause a crash
[23:38:54] <tjtr33> CaptHindsight, i was looking at automation direct stuff ( TECO) when i stumbled on LinMot
[23:39:12] <tjtr33> CaptHindsight, 127mm stroke 3kg mass, vertical
[23:39:43] <anarchos> now if i enter 0.25 into "z coordinate relative to work piece" it does what i want, but stays as Z0.25, not Z0
[23:39:47] <tjtr33> CaptHindsight, 330ms cycle ( i hope ) it seems to be inside their curves
