[00:39:18] <Loetmichel> mornin'
[01:45:52] <Aero-Tec> morning
[01:46:00] <Aero-Tec> well night here
[01:46:18] <Aero-Tec> anyone here good with gcode?
[01:46:32] <Aero-Tec> I am having a problem
[01:47:23] <Aero-Tec> when running the gcode, everything seams fine till I do a tool change
[01:47:43] <Aero-Tec> then I am way off where I should be
[01:48:03] <Aero-Tec> yet when not running code
[01:48:35] <Aero-Tec> when testing where zero is things are fine
[01:50:22] <Aero-Tec> does one need to do a g43 for the offsets to work?
[02:28:29] <DJ9DJ> moin
[02:33:49] <Aero-Tec> morn
[02:34:09] <toastydeath> Aero-Tec, are you running emc
[02:34:25] <Aero-Tec> so does anyone know the best pport setting in the bios?
[02:34:26] <toastydeath> i can't help you in specifics, but in general, you have to call g43 Hxx Dxx
[02:34:29] <Aero-Tec> trying to
[02:34:47] <Aero-Tec> got the tool offset working
[02:35:08] <Aero-Tec> still having problem with the spindle speed
[02:35:15] <Aero-Tec> not sure why
[02:35:25] <Aero-Tec> thought I had it fixed a few times
[02:36:19] <Aero-Tec> H is tool number but what is D?
[02:38:40] <Aero-Tec> I am using pin 11 as spindle index
[02:39:09] <Aero-Tec> not sure if that is a good choice, looks like it is a inverted input
[02:39:16] <Aero-Tec> not sure if that should matter any
[02:39:56] <toastydeath> d is tool radius/diameter
[02:40:05] <toastydeath> which is also tool number
[02:40:19] <toastydeath> i'm not an emc guy, i am a machinist in general
[02:40:39] <toastydeath> if you call H01, also call D01
[02:40:44] <toastydeath> that way cutter comp offset works
[02:51:57] <Aero-Tec> cool
[02:57:36] <Jymmm> Tom_itx: Don't ever divide by zero on AVR atmega32! http://www.youtube.com/watch?v=mZ7pUADoo58&feature=fvwrel
[03:23:27] <Vq> Jymmm: What?!?
[03:23:50] <Jymmm> ¿
[03:28:54] <DJ9DJ> only chuck norris can divide by 0
[03:29:04] <Jymmm> lol
[03:35:24] <Aero-Tec> not sure 100% yet
[03:36:21] <Aero-Tec> but it looks like putting the keyboard on the lathe bed is somehow messing with my spindle speed
[03:36:29] <Aero-Tec> go fig
[03:36:54] <Jymmm> torroids to the rescue!
[03:36:59] <Aero-Tec> the keyboard has a steel bottom
[03:39:41] <Aero-Tec> after the lathe bed being my favorite place to put keyboard for years the paint is getting scratched some
[03:40:42] <Aero-Tec> I was messing with the port cable and unplugged the board
[03:40:56] <Aero-Tec> spindle speed was rock solid
[03:41:28] <Aero-Tec> found board unplugged, plugged it in and spindle not good
[03:41:51] <Aero-Tec> lifted board good, set it down, not good
[03:42:29] <Aero-Tec> after a few time like that I thought this is nuts but it look like I have the answer
[03:42:47] <Aero-Tec> would have never guessed
[03:43:36] <Aero-Tec> still not 100% sold, I have thought I had it fix to many times, time will tell
[05:27:54] <Aero-Tec> not liking EMC so far
[05:28:09] <Aero-Tec> frustrated
[05:28:30] <Aero-Tec> I am working on tool table for lathe
[05:29:10] <Aero-Tec> I zero t1
[05:29:22] <Aero-Tec> g54 work offset
[05:30:43] <Aero-Tec> now I load a new tool, that touch off should be tool table, right?
[05:31:32] <Aero-Tec> and the DRO should now say the location of the tool
[05:31:36] <Aero-Tec> right?
[05:33:37] <Aero-Tec> toastydeath: are you still around?
[05:36:21] <Aero-Tec> is any of the EMC guys here?
[05:41:46] <jthornton> all the EMC guys left only LinuxCNC guys now
[05:42:30] <jthornton> how are you "loading a new tool"
[05:48:06] <Aero-Tec> t1 m6 g43
[05:48:17] <Aero-Tec> found problem I think
[05:48:28] <jthornton> ok
[05:48:34] <Aero-Tec> touch off fixture was active
[05:48:47] <Aero-Tec> should have been touch off work
[05:48:54] <Aero-Tec> that is my guess
[05:48:54] <jthornton> I made some pyvcp buttons to touch off to material
[05:49:14] <jthornton> makes it a one click operation to touch off Z to the material
[05:49:18] <Aero-Tec> so what is the right way to set up tool table?
[05:49:45] <Aero-Tec> I use t1 for the zero for z and x
[05:50:16] <Aero-Tec> so touch off fixture for setting t1?
[05:50:18] <jthornton> well I set mine up by touching off to a fixture and usually use T1 to touch off to the material as it is the correct shape to do so
[05:50:36] <Aero-Tec> and touch off g54
[05:50:43] <jthornton> I touch off all tools to a fixture, in my case the face of the chuck
[05:51:02] <jthornton> then touch off g54 with t1 loaded
[05:51:06] <jthornton> to the material
[05:51:31] <jthornton> make any sense?
[05:51:57] <Aero-Tec> say one wants to set t1 as the zero, and ref all tool offsets from that
[05:52:12] <Aero-Tec> it would if I ran one chuck
[05:53:07] <jthornton> http://www.gnipsel.com/linuxcnc/g-code/gen05.html
[05:53:59] <jthornton> actually I use the face of my spindle as it is a chucker lathe and on my mill I use the top of the vise
[05:56:36] <Aero-Tec> I have quick change chucks, the colet type
[05:56:59] <Aero-Tec> 3 jaw, 6 jaw and a second 3 jaw
[05:57:51] <Aero-Tec> 2 of them have the 2 piece jaws
[05:58:15] <Aero-Tec> not to mention the 4 jaw as will
[05:58:51] <Aero-Tec> I think I know what I am doing wrong
[05:59:07] <jthornton> cool
[06:21:08] <Aero-Tec> thought I had it, now not sure

[07:40:13] <r00t4rd3d> plans and stuff
[10:37:41] <Jymmm> ve7it: Hopefully... By Thusday evening I'll have HF!!!
[10:37:55] <ve7it> yea
[10:38:31] <Jymmm> ve7it: cross fingers, they guy has flaked (justified) on me a few times so far.
[10:38:55] <ve7it> cyber monday here is a bust... wanting a new depth sounder for the boat and nada for sale
[10:39:16] <Jymmm> heh
[10:40:00] <Jymmm> ve7it: I got my Extra in October if I didn't say.
[10:40:37] <ve7it> nice... not sure of US classes... what are they now?
[10:41:06] <Jymmm> Tech General, Extra. Used to be Novice, Tech, General, Advanced, Extra.
[10:41:26] <Tom_itx> that's quite a title
[10:41:44] <Jymmm> Novice and Advanced are just grandfathered
[10:42:02] * Jymmm lol @ Tom_itx
[10:42:11] <Tom_itx> :)
[10:42:20] <Tom_itx> ham?
[10:42:23] <Jymmm> yeah
[10:42:51] <Tom_itx> do you still gotta know the dot dit dit dot stuff?
[10:42:57] <Jymmm> No
[10:43:01] <Jymmm> Not for years.
[10:43:23] <Jymmm> It's still popular though, just not a requirement for any license class.
[10:43:23] <Tom_itx> but do you know it?
[10:43:45] <ve7it> they messed with the Canadian designations a few years back..... used to be amateur(10wpm) and advanced(15wpm) now there is basic, basic+, advanced.. no code now
[10:43:53] <Jymmm> some, need to learn more. Especially after thursday (hopefully)
[10:44:26] <Jymmm> ve7it: Working on my fishtenna this week
[10:45:08] <Jymmm> ve7it: FT-890AT
[10:45:30] <ve7it> can one get 23' fishing rod blanks? I would like to make a rotatable dipole with 2 and an AH-4 tuner
[10:45:43] <Jymmm> ve7it: 32ft actually
[10:46:08] <Jymmm> ve7it: I got two 16.5ft shipped for $27
[10:46:49] <ve7it> a 32'*2 dipole would be a big unit
[10:47:27] <cncbasher> wish i had the space
[10:48:54] <Jymmm> ve7it: --- 31ft pole http://www.jackite.com/product_info.php?cPath=41_44&products_id=132&osCsid=7599def16249698166b1b6147e5f439a
[10:49:47] <Jymmm> ve7it: 16ft $11 http://www.cabelas.com/spinning-rods-cabelas-classic-crappie-pole-1.shtml
[10:51:17] <Jymmm> ve7it: I'm plagerizing the one shown here in the red pipe http://i46.tinypic.com/2rc7cb4.jpg
[10:51:28] <ve7it> why would anyone buy a crappie pole :}
[10:52:04] <Jymmm> ve7it: Because my arms aren't that long.
[10:53:04] <ve7it> nice kit.... I recognize the ceramic tuning coil..... from a ww2 antenna tuner
[10:53:14] <ve7it> I have one in the garage
[10:53:26] <Jymmm> ve7it: actually a defun radio tuner
[10:53:44] <Jymmm> well, that's where he got it from that is
[10:54:37] <Jymmm> ve7it: I picked up some ABS pipe, I still need to figure out how to layout a "thread" pattern on it using the laser.
[10:55:31] <Jymmm> ve7it: Since I dont have a rotary axis on the laser, I can't do a full 360, but I figured I could do a //////// pattern on four sides for the wire to sit into
[10:56:06] <awallin> some company in eastern Finland went bankrupt and they are selling lots of machines: http://www.go-dove.com/en/event-17167/UM-Koneistus-Oy-Finland-Engineering-Facilities-%28In-Bankruptcy%29/lots if I only had the space for those :) ...
[10:56:49] <Jymmm> ve7it: that kit is what he uses aboard ship.
[10:58:27] <Jymmm> cncbasher: space for what?
[10:58:46] <ve7it> http://www.go-dove.com/en/event-17167/lot-14/Cincinnati-Milacron-TT-15-1500-6-Horizontal-CNC-Machining-Centre wow, big machine with 43000hours
[10:59:59] <awallin> just need to fetch that 10ton machine home... :)
[11:01:27] <ve7it> a challenge for the postal service
[11:01:44] <cncbasher> jymmm: a decent rotary hf dipole
[11:02:31] <Jymmm> cncbasher: vertical rotary dipole
[11:03:19] <cncbasher> max dipole i can get up is around 26'
[11:04:00] <Jymmm> what do you, a tower?
[11:04:05] <cncbasher> these people who can manage 6 and 8 ele hf
[11:04:18] <Jymmm> bah
[11:04:40] <Jymmm> no challenge in that =)
[11:05:02] <cncbasher> have a 60' strumech tower but the hf swings over next doors roof
[11:05:34] <Jymmm> and?
[11:06:41] <cncbasher> and thats just a 2 element , just need a to find a farm somewhere rather than in town
[11:11:29] <JT-Shop> cncbasher: I forgot to start my mail program back up after a cold boot last week LOL
[11:12:19] <cncbasher> JT-Shop: u must have felt isolated with no mails .. .haha
[11:13:09] <JT-Shop> that was just on the one computer that I do the docs on so very little traffic anyway
[11:14:17] <skunkworks> wow - vista has a good day or more of updates - starting with sp1... Yeck
[11:14:48] <skunkworks> and that is downloading the network install of sp2
[11:15:18] <cncbasher> catch you next week when the updates have finished ..
[11:16:03] <skunkworks> right
[11:18:40] <Tom_itx> if it still boots
[11:18:56] <skunkworks> so far so good.............
[11:20:04] <skunkworks> get to see if I can activate it... the vista home premium code on the back of the laptop didn't work with the windows home premium cd that I had... go figure
[11:20:19] * skunkworks hugs linux
[11:20:37] <cradek> doctor doctor! it hurts when I do this!
[11:20:56] <skunkworks> if I thought they would use ubuntu....
[12:01:22] <IchGuckLive> hi all
[12:05:19] <IchGuckLive> how woudt you connect a Rs232 PC cable to the servo drive connector ? ->http://foengarage.de/rs232-omron.jpg
[12:05:41] <IchGuckLive> thewre are lots of TXD and RXD but no other DTR ...
[12:05:59] <IchGuckLive> is there only RXD TXD and GND needed
[12:07:04] <awallin> yes 3 wires is the minimal one
[12:07:16] <awallin> no handshaking or hardware flow-control
[12:07:45] <awallin> that picture seems to show differential signals
[12:09:14] <IchGuckLive> do you thik there is a ic in the cable
[12:09:31] <awallin> see the first image here http://www.ethernut.de/en/documents/rs232primer.html that's for devices with a "normal" 9-pin rs232 connector
[12:10:33] <awallin> hm, are you sure they describe that as rs232 and not 422 or something
[12:10:59] <IchGuckLive> the setup is com1 no more
[12:11:38] <awallin> well try a cable that looks like the first pic in my link..
[12:11:49] <awallin> do you have a program for sending stuff to the drive?
[12:12:05] <IchGuckLive> yes xtraware
[12:12:13] <awallin> all the -TX etc. (with a bar) can be connected to GND I guess..
[12:13:12] <IchGuckLive> the 3wire strait cable awallin
[12:13:49] <awallin> yes, but you need to ground /TX /RX also on the servodrive side I think
[12:13:56] <IchGuckLive> that is what i woudt do but on what pin of the 14pin connector
[12:14:33] <IchGuckLive> the pin layout of the 14pin servo drive connector showes npo RX TX
[12:15:11] <awallin> PC(2) to drive(RXD 3 and 10)
[12:15:34] <awallin> and PC(3) to drive(TXD 1 and 8)
[12:15:53] <awallin> but that is just a guess... you never know with these things untli you try..
[12:16:36] <IchGuckLive> ok i did a mail to omron as they provided today also a setup for the Drive and the servo
[12:16:49] <IchGuckLive> maybe i get a layout of the cable
[12:17:57] <IchGuckLive> bevor i pull the servo on this time i will download trhe file to the Driver maybe then i get movement
[12:27:51] <IchGuckLive> soldering on this miniconnectors is quite a hell of work
[12:37:34] <tom3p> mevon_: i got the EMCarduino code but dont know what mods you've made to the Linuxcnc code body.
[12:37:41] <tom3p> I cant imagine how it could respect realtime ( be in position on time/prevent dwells/achieve smooth motion).
[12:37:42] <tom3p> Do you halt the system from the usb or expect Linuxcnc to halt when ferror is too great?
[12:43:14] <skunkworks> just seems like a bad idea
[12:49:52] <tom3p> well, fine for tool changers/proportional valves/chip removal conveyers/ lotsa non-time critical operations
[12:49:52] <tom3p> ( 90% of what you see on a cnc mill/lathe doesnt need realtime, but 10% has to have it )
[12:53:28] <mrsun> http://www.youtube.com/watch?feature=player_embedded&v=IULLSmhsB6M heh =) cool =)
[13:03:46] <IchGuckLive> mrsun: the monitors are qwuite Dark O.O
[13:04:58] <mrsun> IchGuckLive, huh ?
[13:05:41] <IchGuckLive> the blind man in the vid
[13:06:16] <mrsun> yeah but i dont get the "the monitors are quite dark" ?
[13:42:25] <JT-Shop> how do you make refractory cement?
[13:44:59] <cncbasher> www.backyardmetalcasting.com
[13:45:20] <JT-Shop> LOL I was reading that site
[13:46:02] <cncbasher> i usualy buy refactory
[13:46:32] <cncbasher> and get the stuff rated for 1700 deg
[13:46:57] <JT-Shop> I'm looking at casting some aluminum for fun
[13:47:01] <cncbasher> i found the homemade stuff ok for a while , but didnt last long
[13:47:38] <cncbasher> it's great fun
[13:48:11] <JT-Shop> what fuel do you use?
[13:48:15] <cncbasher> i bought a kiln too and use that for aluminium
[13:48:37] <JT-Shop> I have a huge kiln that's never been used for anything
[13:48:43] <cncbasher> gas and air blower ,,, but oil is good too
[13:49:25] <cncbasher> some kilns will go higher and will melt aluminium fine
[13:50:47] <cncbasher> i have fancied making an oil burner , but not got round to it as yet
[13:51:24] <JT-Shop> this is the kiln http://imagebin.org/237245
[13:51:40] <cncbasher> nabertherm ?
[13:51:57] <JT-Shop> it goes to 2350F
[13:52:10] <cncbasher> that should do aluminium ok
[13:52:32] <JT-Shop> Olympic Electric Kiln Co.
[13:53:09] <JT-Shop> I'm thinking of taking the top and bottom sections out and just use the center section
[13:53:10] <cncbasher> if anyting it may be one section too high
[13:53:41] <cncbasher> yea i thought it looked as if it split in layers
[13:54:03] <JT-Shop> it's 27" inside height
[13:54:08] <tom3p> the unused section becomes backyard pizza parlor
[13:54:12] <cncbasher> you'll probably need 2 sets of elements to get the temp up
[13:55:29] <cncbasher> i use the kiln for small aluminium jobs , and the furnace for larger and also cast iron
[13:55:50] <cncbasher> i'll send you some stuff by email
[13:55:56] <JT-Shop> ok thanks
[13:56:20] <cncbasher> need to dig it out first
[13:56:56] <cncbasher> then i'll send you some download links
[13:57:09] <JT-Shop> thankw
[13:57:10] <JT-Shop> s
[13:57:54] <mrsun> JT-Shop, for alu casting you can use just about any refractory .. go to a place that makes chimneys or something :P
[13:58:03] <mrsun> or what they are called =)
[13:58:12] <mrsun> just get something rated like 1100 degree C or someting
[13:58:19] <JT-Shop> the red flue things
[13:58:26] <mrsun> mix it with vermaculite and ram it into shape =)
[14:00:05] <Loetmichel> mrsun: bah, doent that SMELL awful when burning from the molten alu?
[14:00:15] <Loetmichel> doesent
[14:00:21] <mrsun> what smells ?
[14:00:29] <Loetmichel> vermaculite
[14:00:48] <mrsun> its for getting insulating properties in the refractory
[14:00:52] <mrsun> its not supposed to be in the alu :P
[14:01:51] <Loetmichel> ah, sorry.... read that as vegemite
[14:01:53] <Loetmichel> ;-)
[14:02:11] <mrsun> http://en.wikipedia.org/wiki/Vermiculite
[14:02:29] <Loetmichel> and thought you wanted to "glue" the sand for casting
[14:02:53] <Loetmichel> mrsun: yeas, read that the second time... ;-)
[14:04:00] <mrsun> refractory isnt realy rocket science until you need to melt steel :P
[14:07:35] <mrsun> i think the lowest grade of furnace cement i can find here is for 1200 or 1300 degrees C =)
[14:08:00] <mrsun> JT-Shop, furnace cement was the word i was looking for :P
[14:08:03] <mrsun> i think ;P
[14:08:09] <mrsun> or fireclay
[14:08:11] <mrsun> works also
[14:09:02] <ds3> you do have a battery on there right?
[14:09:08] <mrsun> getting powder coating off without doing it mechanicaly is rocket science it seems tho :P
[14:09:14] <ds3> blah
[14:12:09] <L84Supper> thermosets tend to be that way
[14:12:26] <djdelorie> ah, the benefits of having a cnc machine handy... needed a new house number sign for the driveway, just had the machine carve me one :-)
[14:13:16] * djdelorie needs to find a better paint-resistant film to stick on though, besides paper and spray glue :-)
[14:14:12] <Loetmichel> mrsun: steel underneath? oder aluminium?
[14:14:25] <mrsun> steel
[14:14:28] <L84Supper> mrsun: do you know what kind of powdercoat it is? polyester, epoxy ?
[14:14:33] <mrsun> dont know
[14:14:42] <mrsun> could ask the firm that has painted it :P
[14:14:44] <Loetmichel> steel is simple: NaOh 30% in water, at 80°c or so
[14:14:55] <mrsun> tried 2 different commercial paint strippers, one water based and one solventbased
[14:14:59] <Loetmichel> half an hour-> powder coatoing gone
[14:15:04] <Loetmichel> coating
[14:15:35] <mrsun> Loetmichel, tried NaOH tho not at 80 degrees but mixed with something so it wont dry, been sitting for 24 hours and nothing
[14:15:44] <mrsun> not a single dent
[14:15:45] <L84Supper> yes, it's not paint, it's actually polymerizes when it cures, so you're trying to dissolve a polymer
[14:15:59] <L84Supper> or an epoxy
[14:16:11] <djdelorie> Note: NaOH is an organic solvent. Your skin is organic...
[14:16:11] <Loetmichel> mrsun: you have seen the concentration?
[14:16:23] * Loetmichel seconds taht note strongly
[14:16:34] <mrsun> Loetmichel, 30g to 100g water i had
[14:16:46] <L84Supper> what was the powder coated metals intended use? that might be a clue as to what type it is
[14:16:50] <Loetmichel> that sounds about right
[14:16:52] <mrsun> djdelorie, burned a bit to get it on me :P
[14:16:59] <Loetmichel> and hot is has to be
[14:17:10] <mrsun> L84Supper, its for cabinets etc for tools
[14:17:12] <mrsun> indoor use
[14:17:22] <L84Supper> might be an epoxy then
[14:17:27] <Loetmichel> most likely polyester
[14:17:31] <mrsun> haha
[14:17:42] <djdelorie> In the USA, NaOH is found under "drain cleaners" in hardware stores, just make sure you get the NaOH variant and not the "safe" variant
[14:18:18] <Loetmichel> DJ9DJ: and be sure to sieve the aluminium particles out, the produce oxygen but weaken the naoH
[14:18:24] <Loetmichel> grr
[14:18:27] <L84Supper> polyester tends to be used for outdoor apps
[14:18:28] <Loetmichel> djdelorie
[14:18:39] <mrsun> djdelorie, yes i have NaOH i use it when i make pcbs
[14:18:52] <djdelorie> me too, that's why I know where to buy it :-)
[14:18:56] <L84Supper> epoxy is tougher but does not do well over extended periods in UV (outdoors)
[14:19:24] <djdelorie> "making pcb's: the art of using all the very dangerous but easily obtainable home chemicals" :-)
[14:19:26] <mrsun> the paint stripper i used "worked" but it would cost me more in paint stripper and work to get it off then to go buy new tubing ...
[14:19:45] <mrsun> had to apply, then scrape off a layer, then apply again etc etc
[14:19:51] <L84Supper> mrsun: was it an acid type stripper?
[14:19:54] <mrsun> i want something that works like all the youtube videos
[14:20:08] <mrsun> L84Supper, not sure realy ...
[14:20:09] <djdelorie> if NaOH fails, try Goof Off (xylene/tolulene). Also extremely dangerous to humans, but a strong solvent
[14:20:34] <mrsun> djdelorie, thing is that im in sweden ... they ban everything that works good in this country
[14:20:44] <mrsun> and its almost impossible to get good stuff in stores ..
[14:20:55] <mrsun> stupid country
[14:21:18] <mrsun> "lets make something that is 1/3 as dangerous as this but make it work 1/6 as good" .. well done
[14:21:41] <mrsun> a more dangerous product due to the fact that you need to use lots and lots of it, but per volume its alot less dangerous then the previous version
[14:21:49] <djdelorie> around here, you can by hazardous chemicals at the local hardware store, firearms at Wal*Mart, but you can't legally get anything to help you lose weight or watch BluRay disks you already own.
[14:22:07] <cradek> or clear your sinuses?
[14:22:14] <djdelorie> (well, unless you buy into the cartels, of course)
[14:23:19] <L84Supper> the non-polar solvents won't do much to reduce the epoxy
[14:23:32] <djdelorie> acetone for epoxy?
[14:23:32] <Jymmm> Goof Off isn't xylene, but naphatha
[14:24:09] <Jymmm> If it's lithium/grease, use charcoal lighter fluid.
[14:25:27] <djdelorie> all it says on the can wrt ingredients is "Warning: contains xylene"
[14:25:41] <Jymmm> cigar lighter fluid is also naphtha, good for removing adhesive sticker residue.
[14:25:52] <djdelorie> afaik, it's the xylene that makes it a wicked solvent
[14:26:14] <Jymmm> for grease?
[14:26:30] <djdelorie> for pretty much everything I've tried it on :-)
[14:27:05] <Jymmm> xylene is just a slow evaporating acetone.
[14:28:00] <Jymmm> But to remove adhesive residue, naphatha works great, which is also Cigar lighter fluid.
[14:28:21] <Jymmm> For grease, bbq charcoal fluid.
[14:28:45] <Jymmm> is the only thing I found (other than gasoline) that works well.
[14:29:14] <djdelorie> I first experienced goof-off when a relative used it to remove "road tar" off a car. That's also when I noted it removed the paint if you weren't careful ;-)
[14:29:40] <Jymmm> I stay away from Toulene, that shit will easily fuck you up.
[14:30:03] <djdelorie> I have a bunch of different solvents to go with all the woodworking stuff, but goof-off is the "last-ditch" option for stubborn stuff
[14:30:04] <Jymmm> Yeah, xylee will do that, naphtha won't
[14:30:30] <djdelorie> naptha will take wax off a wood finish, without taking the finish off. Useful stuff.
[14:30:44] <Jymmm> naphatha will soften road tar and the like
[14:31:04] <Jymmm> so will 180F water =)
[14:31:06] <L84Supper> Methylene chloride (dichloromethane) for epoxy
[14:31:26] <Jymmm> L84Supper: Fuck you!
[14:31:29] <djdelorie> water messes up the wood, though, if it gets through. Typically you use organics if you can.
[14:31:31] <mrsun> L84Supper, been looking for something here with that in but cant find anything
[14:31:41] <Jymmm> L84Supper: dont be fucking with ckrlo shit =)
[14:31:45] <L84Supper> NMP and MEK
[14:32:02] <djdelorie> who knew woodworking required a chemistry background? ;-)
[14:32:12] <L84Supper> not that you'd want to use any of these without proper safety precautions
[14:32:46] <Jymmm> djdelorie: Sulfuric acid for aging wood
[14:33:01] * djdelorie normally only uses new wood
[14:33:19] <L84Supper> Sulfuric acid will also cut many epoxies well
[14:33:28] <Jymmm> brn wood is hard and harder to find these days
[14:33:31] <Jymmm> barn
[14:34:05] <Jymmm> L84Supper: o, I don't want to wear a hazmat suit to do hobby tyvm
[14:34:12] <Jymmm> s/o/No/
[14:34:23] <L84Supper> you can also burn it off, but it produces lots of nasty things as it decomposes
[14:34:47] <mrsun> ive been welding close to it, not very plesant smoke :P
[14:34:52] <mrsun> thats why i want it removed
[14:35:02] <Jymmm> mrsun: what?
[14:35:04] <L84Supper> best bet is to not use epoxy coated metal
[14:35:07] <Jymmm> mrsun: what removed?
[14:35:11] <mrsun> powder coating
[14:35:29] <mrsun> L84Supper, i got a buttload of 50x50x2 profiles with it :/
[14:35:39] <Jymmm> it's a polymer, soooooooooo
[14:36:07] <Jymmm> mrsun: I'd suggest a big field and a bond fire to remove it
[14:36:45] <Jymmm> or LN2
[14:36:47] <L84Supper> yeah, the powdercoat was designed to stay on
[14:37:31] <mrsun> well i guess the wirebrush will have to make the parts i need to weld clean so i can weld it without inhaling that shit
[14:37:39] <mrsun> then just fix it up and paint over it :P
[14:38:06] <jdh> I need a 1/4" female BSPP to 1/4" Male NPT. Anyone have one laying around?
[14:38:08] <L84Supper> and a fan + ventilation, stay upwind when you weld
[14:38:10] <Jymmm> gasket remover??? http://www.choppersurplus.com/global/articles/howtoremovepowdercoating.html
[14:38:37] <jdh> why do you boot?
[14:38:40] <mrsun> Jymmm, tried to find it around here, cant find anything .. sure they can take it home but as its not a normal product for them i get to wait etc :/
[14:39:20] <L84Supper> really really powerful UV lamps will do it as well, but it might take a few weeks
[14:41:04] <Jymmm> mrsun: Dichloromethane?
[14:41:52] <Jymmm> oh, Freon
[14:43:08] <Jymmm> It's banned in EU since 2010
[14:43:23] <Jymmm> mrsun: Got Field?
[14:43:37] <Jymmm> or just torch it off
[14:45:30] <L84Supper> http://www.aerochem.net/dekote-af
[14:47:01] <L84Supper> Benzyl Alcohol, Aromatic Hydrocarbon, Hydrogen Peroxide, Dioxolane
[14:50:43] <L84Supper> they don't break the polymer chain but try to get underneath the coating and break the bond to the substrate
[15:18:50] <_abc_> Good evening. Has anyone here tinkered with case hardening small mill bits to be used in the linuxcnc context?
[15:18:58] <_abc_> Carburizing, specifically
[15:19:22] <_abc_> I found a quite detailed paper on carburization of small bits and I would like to try it
[15:19:58] <_abc_> But has anyone tried this? The purpose is to sharpen, carburize, and temper broken off expensive small (<1mm) mill bits for reuse.
[15:30:33] <sliptonic> I'm getting ready to replace the motherboard for my mill controller. Someone was recommending this one not long ago: http://www.newegg.com/Product/Product.aspx?Item=N82E16813128452 but it's discontinued. Anyone have a suggestion?
[15:36:27] <JT-Shop> might read the computer part of the forum
[16:09:13] <sliptonic> Thanks JT-Shop. I will. Also, I recall someone posting a link to a drive. IIRC it was a solid state sata drive that plugged directly into the sata port without a cable. I haven't been able to find it though so I'm probably using the wrong googleons.
[16:10:18] <JT-Shop> I think andypugh uses something like that
[16:10:40] <andypugh> Someone just sent me this link. I think the URL is fairl self-explanatory. http://scanlime.org/2012/11/hacking-my-vagina/
[16:10:43] <JT-Shop> I remember some discussion of late on diffrent mother boards
[16:11:14] <andypugh> sliptonic: http://www.ebay.com/itm/Kingspec-8GB-SATA-DOM-MLC-Flash-SSD-Disk-On-Module-Network-PC-Solid-State-Drive-/310421036909?pt=US_Solid_State_Drives&hash=item4846891f6d
[16:12:41] <sliptonic> Thanks andypugh. That's the one.
[16:21:27] <DJ9DJ> gn8
[16:39:19] <tjb1> Evening all
[16:57:49] <tjb1> Im gonna dump all homing and just use my switches as limits
[17:00:15] <JT-Shop> not having any luck?
[17:01:00] <JT-Shop> I thought you had some extra parallel port inputs?
[17:04:41] <tjb1> I dont home really so doesnt matter to me
[17:45:30] <tjb1> JT-Shop: What is the purpose of homing a stepper setup?
[17:48:02] <JT-Shop> so my rapid to home button works and the soft limits work
[17:48:04] <icee> tjb1: you have to set up your coordinate system somehow
[17:48:28] <tjb1> icee: I can do that with touch offs
[17:48:34] <tjb1> Which I do every time I run it anyway
[17:48:54] <icee> tjb1: that will get you work coordinates, but not machine coordinates.. i prefer not to bump limit switches
[17:49:11] <JT-Shop> jep, jog to the start position and fire in the hole
[17:49:55] <tjb1> If the time comes I will work out how to do it with 1 input…just gonna be limits for now
[17:53:46] <tjb1> Oh JT-Shop, I have to invert the arc_ok signal in thcud or maybe change the probing to L3?
[17:55:24] <JT-Shop> qu
[17:56:11] <tjb1> If I set arc_ok to -not, thcud works but the M66 doesnt
[17:56:41] <tjb1> I remove -not, M66 works and thcud doesnt
[17:56:55] <JT-Shop> I don't think they are related unless you did something in hal
[17:58:04] <tjb1> The M66 is waiting for digital input from arc_ok before it starts motion
[17:58:41] <Tom_itx> icee are you icee from years back?
[17:58:48] <Tom_itx> in #electronics?
[18:01:29] <tjb1> I dont know if changing it from L4 to L3 will work or if I am going to have to go into the comp file and put !arc_ok instead
[18:01:37] <JT-Shop> what does M66 have to do with probe input?
[18:02:36] <Tom_itx> waits for input?
[18:02:52] <JT-Shop> oh I'm confused now
[18:03:42] <JT-Shop> M66 P0 L1 Q2 (Wait 2 seconds for Arc OK from Torch)
[18:03:43] <tjb1> sorry I didnt mean probe
[18:03:49] <tjb1> I meant arc_ok
[18:04:32] <icee> Tom_itx: yes, yes i am
[18:04:47] <Tom_itx> i thought you were
[18:04:48] <Tom_itx> wb
[18:04:59] <Tom_itx> how long have you been hangin out in here?
[18:04:59] <icee> :) thx
[18:05:04] <icee> hmm, a few days
[18:05:05] <JT-Shop> net start-motion-input motion.digital-in-00 <= hm2_5i25.0.7i76.0.0.input-04
[18:05:10] <JT-Shop> net start-motion-input => thc-pid.arc-ok
[18:05:17] <icee> i've had emc2 for quite awhile on my mill, but i'm contemplating doing new/fancier things with it so lurking
[18:05:23] <JT-Shop> tjb1: that's what I use
[18:05:38] <Tom_itx> icee, i didn't realize you were into cnc
[18:06:12] <Tom_itx> it's come a long ways
[18:06:30] <tjb1> JT-Shop: My arc_ok sinks the signal so its coming back false in LinuxCNC if I dont invert it. I have M66 watching the signal go low(L4) which works when its not inverted…if I invert it, would L3 watching it go high now work?
[18:07:56] <JT-Shop> what does the manual say?
[18:08:54] <JT-Shop> maybe I should use L3 too
[18:09:23] <tjb1> "Better not tell you now" :)
[18:09:36] <tjb1> "Reply hazy, try again"
[18:10:22] <JT-Shop> I did get my edge radius subroutine sorted out for the lathe
[18:10:32] <Tom_itx> well is it waiting for a rising or falling edge?
[18:11:09] <tjb1> high or low
[18:11:30] <JT-Shop> the manual seems to imply that mode 3/4 are for dio and mode 1/2 are for aio
[18:12:00] <tjb1> 0 is only allowed on an analog
[18:12:32] <JT-Shop> I think that is misworded
[18:14:29] <JT-Shop> I had a rather sucessful metal spinning today
[18:14:37] <tjb1> Ill try the L3, if not I will change the comp file
[18:14:53] <tjb1> What did you make?
[18:14:59] <JT-Shop> a cup
[18:15:09] <JT-Shop> with ruffles
[18:15:28] <JT-Shop> or a dish rather
[18:15:49] <tjb1> Do you have to use a form to do that?
[18:16:14] <JT-Shop> working on tools and technique more than anything
[18:16:24] <JT-Shop> yea, I'll get a photo of it
[18:18:53] <JT-Shop> http://imagebin.org/237266
[18:20:53] <tjb1> Pretty cool
[18:21:25] <JT-Shop> thanks, that ain't the first one LOL
[18:21:41] <JT-Shop> getting better at reading the metal as I spin
[18:22:09] <Tom_itx> what you makin?
[18:22:49] <Tom_itx> i guess it pays to read the scroll back
[18:23:29] <JT-Shop> well the plan is to spin a bullet shaped cap for a 105mm case to use as an urn for my neighbor
[18:24:09] <JT-Shop> well see if we get done before it is needed... otherwise he has been put on notice that a cardboard box will be used
[18:24:24] <Tom_itx> heh
[18:24:48] <Tom_itx> workin kinda close to the spindle there to be spinnin metal
[18:24:55] <Tom_itx> it's gonna grow quite a bit
[18:25:25] <JT-Shop> http://imagebin.org/237269
[18:25:26] <tjb1> What is this
[18:25:27] <tjb1> http://imagebin.org/237245
[18:25:45] <JT-Shop> a kiln
[18:26:03] <JT-Shop> it will go to 2350F
[18:26:09] <Tom_itx> used as intended or for heat treat?
[18:26:37] <JT-Shop> pottery mostly, I thought I might want to use it for heat treating but it is too big
[18:27:14] <JT-Shop> it's brand new, I've only warmed it up once...
[18:27:21] <Tom_itx> heh
[18:27:31] <Tom_itx> is pottery still popular?
[18:27:43] <Tom_itx> it was here for a while and kinda died off
[18:27:56] <JT-Shop> dunno, you can also slump bottles in there
[18:29:06] <JT-Shop> that still ain't a good photo of the spun part
[18:30:08] <tjb1> http://www.rainymood.com/
[18:30:54] <JT-Shop> raining here
[18:32:06] <tjb1> Isn't going to rain here for probably another 3-4 months
[18:32:27] <JT-Shop> http://imagebin.org/237270
[18:32:43] <JT-Shop> damn phone is dusty
[18:32:53] <tjb1> Should probably answer your phone more often
[18:32:58] <tjb1> 40 missed calls
[18:33:06] <JT-Shop> 48
[18:33:50] <Tom_itx> same guy keep calling?
[18:33:51] <Tom_itx> :)
[18:33:52] <JT-Shop> know what the thing on the keyboard is?
[18:34:03] <tjb1> You knapp that yourself?
[18:34:19] <tjb1> A horn for your viking helmet?
[18:34:19] <JT-Shop> no, I make the tools for a buddy
[18:34:34] <JT-Shop> he made me a knife for my efforts
[18:34:45] <JT-Shop> that's a knapping tool
[18:35:28] <Tom_itx> lord knows you take enough naps
[18:35:45] <tjb1> I took a nap in a treestand today
[18:36:22] <JT-Shop> never have enough naps
[18:36:34] <tjb1> Where you finding all the horns?
[18:36:40] <tjb1> I havent seen a deer with horns in years lol
[18:36:43] <JT-Shop> Gary
[18:36:50] <Tom_itx> probably in his back yard
[18:37:11] <JT-Shop> Gary has a tote box full of them
[18:37:26] <JT-Shop> there too
[18:37:39] * Tom_itx goes for a shower
[18:38:07] <JT-Shop> thank goodness... it was getting a bit rough here
[18:39:58] <tjb1> I have a feeling when I buy that intel d525 im gonna have problems all over again
[18:40:45] <tjb1> Anyone happen to know if normal PCI cards fit on that mobo?
[18:41:33] <JT-Shop> card not cards
[18:41:53] <JT-Shop> depends on your case really
[18:42:48] <tjb1> http://www.newegg.com/Product/Product.aspx?Item=N82E16811352009
[18:44:18] <tjb1> Hell some of them cost more than the board
[19:04:06] <Tom_itx> ahhh much better
[19:23:45] <Loetmichel> tjb1: ONE
[19:24:01] <tjb1> ?
[19:24:18] <Loetmichel> ONE PCI card
[19:24:24] <Loetmichel> fits on the D525
[19:25:59] <Loetmichel> and for casings: "when there is a Will, there is a way" as we say in germany.
[19:26:26] <Loetmichel> and so my CNC cpu is inside an old 80286 "pizzabox" case:
[19:26:39] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12265
[19:26:44] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12250
[19:26:50] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12247
[19:27:11] <Loetmichel> and its not an mini-itx, its a flex-atx board ;-)
[19:27:36] <Loetmichel> (OK, the cpu fan is a press fit under the hood ;-)
[21:47:38] <skunkworks> yikes

[21:56:22] <cradek> http://www.youtube.com/watch?v=E3AqIZURMbI
[21:56:43] <cradek> that's cute and all, but you're spending like 5% of the time cutting
[21:58:37] <cradek> oh ok, it gets better later.
[21:59:47] <toastydeath> whoever was programming this didn't pay attention to the checkboxes in mastercam
[22:05:11] <Tom_itx> that looks like a fadal. no audio here so i'm not sure if they said
[22:07:15] <Tom_itx> they used surfcam
[22:07:27] <Tom_itx> i kinda like surfcam but i've never used it
[22:07:36] <Tom_itx> a bud of mine had it and used it
[22:09:57] <r00t4rd3d> http://i.imgur.com/3uhsV.png
[22:10:19] <r00t4rd3d> i can run ubuntu on my phone :/
[22:13:28] <Tom_itx> i haven't seen a fadal yet that would last cutting steel, let alone at those speeds
[22:18:53] <tjb1> r00t4rd3d: arent you speshul
[22:19:35] <r00t4rd3d> do that on your iphone
[22:21:21] * Tom_itx looks at his flip phone and wonders where to try and load it
[22:25:56] <skunkworks2> alex_Joni, did you get it?
