[02:57:28] <Jymmm> If you use firefox ff and get annoyed by the long urls that is give when searching google you can add a new search engine called MyGoogle.xml and add this contents: http://codepad.org/qWyn1wgK you will need to restart FF for it to take effect.
[02:58:17] <Jymmm> Best to completely shut down ff, add that file, then start ff
[03:06:24] <Loetmichel> mornin'
[04:35:07] <SpeedEvil> Jymmm: Won't someone think of the search ratings!
[05:31:56] <Jymmm> SpeedEvil: ???
[05:32:59] <SpeedEvil> By doing that, you worsen googles search as it can't pick up the clicks
[05:33:46] <Jymmm> hardly
[05:34:49] <Jymmm> IT's the difference between this:
[05:34:53] <Jymmm> http://www.google.com/search?q=linuxcnc
[05:35:04] <Jymmm> and this:
[05:35:05] <Jymmm> https://www.google.com/search?q=linuxcnc&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a&channel=sb
[05:35:59] <SpeedEvil> Oh - I know
[05:36:15] <SpeedEvil> Oh - I thought you meant the stupid long result URLs
[05:37:05] <Jymmm> These... http://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0CB8QFjAA&url=http%3A%2F%2Fwww.linuxcnc.org%2F&ei=zwveU_ztJ5fhoAS-vIKQCQ&usg=AFQjCNG0pw1dLoWUGxLDqm-UIkMT2d2yvw&sig2=7w-ZBmTL5PKC4WMaltVu5A&bvm=bv.72197243,d.cGU

[09:10:10] <SpeedEvil> :)
[10:42:16] <jthornton> h o w can I download the latest LinuxCNC in the middle of the night
[10:42:43] <humble_sea_bass> buy it dinner
[10:43:01] <humble_sea_bass> linux don't like straight up booty calls
[10:44:01] <jdh> at 2am wget url
[10:45:58] <jthornton> can you set wget to run at night or do I need to figure out how to do a cron job or whatever it is called
[10:46:53] <cpresser> jthornton: you can use 'sleep 12345; wget url' if you only want to do it once
[10:48:50] <jthornton> ok thanks
[10:48:58] <jthornton> and sleep is seconds?
[10:51:16] <cpresser> seconds, yes
[10:52:02] <jthornton> thanks
[10:53:32] <SpeedEvil> or 8h
[10:55:06] * jthornton does man sleep
[11:28:19] <IchGuckLive> hi all B)
[11:29:47] <IchGuckLive> archivist ?
[11:29:58] <IchGuckLive> hi eeriegeek
[11:30:41] <IchGuckLive> archivist_herron: ?
[11:33:25] <XXCoder2> hey
[11:37:06] <ssi> anyone have any thoughts on a way to make linuxcnc unhome all axes when machine is disabled?
[11:37:43] <syyl_ws> why would one?
[11:37:45] <syyl_ws> oO
[11:37:57] <ssi> I have my reasons :)
[11:38:06] <syyl_ws> thats a good reason ;)
[11:38:20] <syyl_ws> (no, never made any thoughts on that)
[11:38:24] <ssi> the gantry tends to want to be out of square
[11:38:30] <ssi> and with dual-homing, I can make it square
[11:38:39] <ssi> but when the machine is disabled, it pops back to where it tends to want to be
[11:38:44] <syyl_ws> ah ok
[11:38:47] <syyl_ws> got it :)
[11:38:50] <ssi> so if I disable then reenable, the machine thinks its homed, but it's WAY out
[11:39:06] <ssi> so I want to basically force a rehome anytime the drives get disabled
[11:39:15] <ssi> otherwise I know I'm going to forget and screw up a part
[11:39:21] <syyl_ws> wont you get a following error if the axis move by themself?
[11:39:26] <ssi> not with steppers
[11:39:32] <syyl_ws> aw, not feedback :D
[11:39:36] <ssi> right :)
[11:39:57] <IchGuckLive> ssi: do it your way
[11:39:57] <syyl_ws> im a bit spoiled with linear scales and steppers ;)
[11:40:18] <ssi> linear scales aren't really practical with two 24" travels and a 48" travel
[11:40:26] <ssi> IchGuckLive: my way?
[11:40:29] <syyl_ws> that will get a bit costly
[11:40:37] <IchGuckLive> unhome at every Gcode end
[11:40:51] <IchGuckLive> use a User mcode
[11:41:02] <syyl_ws> thats a horrible solution Oo
[11:41:06] <ssi> but it's not just at the end of gcode that it's an issue
[11:41:17] <ssi> it's if I hit F1 or F2 to disable the machine and walk away
[11:41:21] <syyl_ws> always homing the machine before running a programm
[11:41:22] <ssi> then come back and reenable and try to run something
[11:41:23] <syyl_ws> Oo
[11:41:23] <ssi> it'll be a problem
[11:41:26] <IchGuckLive> you are the mashine constructor
[11:41:33] <IchGuckLive> BAD
[11:41:47] <ssi> uhm
[11:41:55] <ssi> I'm sorry i don't meet your standards?
[11:42:09] <IchGuckLive> laser shoudent be ofset on a 3hr burn by 0.1mm
[11:42:28] <syyl_ws> you didnt understand his problem, hu?
[11:42:31] <ssi> I'm not sure we're talking about the same thing :P
[11:43:17] <syyl_ws> ;)
[11:43:23] <ssi> I may be able to write a component that does it
[11:43:27] <IchGuckLive> ok my english understanding is far from perfect
[11:43:36] <ssi> I jsut have to figure out how to interact with axis
[11:43:41] <ssi> or something
[11:44:08] <IchGuckLive> gantry homing there are plenty of comps out even kenetics can handle this
[11:44:49] <ssi> homing is done
[11:46:53] <ssi> I pretty much only know how to interact with hal
[11:47:05] <ssi> there's no hal pins for things like home/unhome, and free/teleop mode
[11:47:24] <ssi> I have some magic sauce that I got off the forum that goes in axisrc to auto-teleop-mode
[11:47:40] <ssi> and it does that like this:
[11:47:41] <ssi> c.teleop_enable(1)
[11:47:54] <ssi> I don't know what c is or where it comes from; it just is already in scope in axisrc somehow
[11:48:10] <ssi> I need to figure out how to do the same stuff from within a component
[11:48:21] <ssi> which might not be possible
[11:48:39] <PetefromTn_> afternoon guys
[11:48:49] <ssi> hm maybe pyvcp
[11:48:56] <PetefromTn_> and gals if there are any here.
[11:49:26] <CaptHindsight> anyone ever see what machine 80/20, Faztek etc uses for high volume tapping of t-slot?
[11:51:59] <IchGuckLive> ssi the c comes from the internal interpreter linuxcnc is internal c.
[11:52:19] <IchGuckLive> look inside glcanon
[11:52:25] <XXCoder2> heys
[11:52:36] <XXCoder2> capt wonder if guy used drill press with kig
[11:52:39] <XXCoder2> jig
[11:54:27] <CaptHindsight> XXCoder2: probably not
[11:54:39] <XXCoder2> why not? I bet it saves lot of time
[11:54:58] <CaptHindsight> vs prayer?
[11:55:23] <humble_sea_bass> "oh heavenly father, let this tap not break"
[11:55:28] <XXCoder2> lol
[11:55:53] <PetefromTn_> LOL I've said that prayer a few times
[11:56:11] <syyl_ws> it most times followed by "crapcrapcrap"
[11:56:22] <humble_sea_bass> damn right
[11:56:28] <syyl_ws> and a walk to the edm guy
[11:56:31] <syyl_ws> to burn it out
[11:56:56] <PetefromTn_> I hate tapping stainless.
[11:57:28] <syyl_ws> i went to thread milling in those !!!"(/Xyy materials
[11:57:32] <syyl_ws> way more relaxing
[11:57:40] <syyl_ws> as a broken thread mill can just be blown out
[11:57:42] <PetefromTn_> I remember the shop I worked in on the last two days I worked there my friend had to tap like fifty holes in this large 3/8 stainless plate.
[11:58:09] <IchGuckLive> making parts out of 2316 is a nightmar
[11:58:15] <PetefromTn_> they ordered some diffiuclt to tap and machine because it saved them a couple bucks.
[11:58:53] <PetefromTn_> He wound up after rigid tapping very shallow just to get a thread started and finishing by hand carefully STILL breaking four taps in the part.
[11:58:54] <XXCoder2> PetefromTn_: guess they dont realize employee time is more spendy than once bill of tools
[11:59:04] <CaptHindsight> XXCoder2: https://d2t1xqejof9utc.cloudfront.net/screenshots/pics/d221aa7cf54f87348840da11756873ee/medium.jpg if you wanted to tap that center hole in the extrusion and the length of the part is anywhere from ~1/4" to 210", would you use a drill press?
[11:59:06] <PetefromTn_> Oh hell no
[11:59:46] <syyl_ws> i would use one of those parallel taping arms
[11:59:58] <syyl_ws> that would be the right thing for the job
[12:00:08] <humble_sea_bass> i have a drill press as tall as the brooklyn bridge
[12:00:11] <XXCoder2> capt with some good jig sure. just make it hold 8020 by side slot
[12:00:23] <XXCoder2> ah but if in side then its impossible
[12:00:27] <PetefromTn_> They were always cheaping out on cutters and materials most times taking it in the ass afterwards because of broken tooling and lots time.
[12:00:35] <IchGuckLive> humble_sea_bass: russians liker that size of mashine
[12:00:39] <syyl_ws> radial arm drill with a hole in the ground next to it
[12:00:40] <syyl_ws> :D
[12:00:50] <syyl_ws> a lokal shop here had such a setup
[12:01:08] <XXCoder2> *in end I mean
[12:01:15] <syyl_ws> to drill long parts on the face
[12:01:45] <syyl_ws> drop the part in the hole, clamp it against the square table of the machine and youre off to go :D
[12:02:17] <PetefromTn_> you talking about a large radial drill?
[12:02:25] <syyl_ws> yeah
[12:02:33] <CaptHindsight> I wonder if a drill can operate sideways, like a wall mount lathe?
[12:02:33] <syyl_ws> that was a pretty cool setup
[12:02:41] <PetefromTn_> yeah they are sweet. They had a HUGE one at the shop I was working in.
[12:02:47] <syyl_ws> why not?
[12:02:53] <syyl_ws> like in a horizontal boring mill
[12:03:03] <XXCoder2> 90 degree turn for drill bit?
[12:04:16] <CaptHindsight> how would a drill press handle backing the tap out of the hole, reversing switch?
[12:04:42] <IchGuckLive> PetefromTn_: http://www.iam.com.pl/data/images/Auslegerbohrmaschine.jpg
[12:04:42] <XXCoder2> cross one of belts? hmm likely wont work lol
[12:04:44] <PetefromTn_> sure...have you never power tapped in a drill press/
[12:04:44] <humble_sea_bass> doesnt the extrusion alrealy have a hole down center
[12:04:56] <XXCoder2> humble_sea_bass: nontapped
[12:05:27] <humble_sea_bass> you don't need to tap more than a few inches
[12:05:27] <PetefromTn_> IchGuckLive Yeah that is similar to the one they have there but I think theirs is probably larger.
[12:05:31] <CaptHindsight> heh, yeah t-slot comes extruded with the proper hole size ready to just be tapped
[12:06:19] <CaptHindsight> I wonder what 80/20, Bosch and other suppliers use for production
[12:07:04] <CaptHindsight> they handle all the special orders and charge ~$1 per hole tapped
[12:07:30] <IchGuckLive> PetefromTn_: "i" make most parts for the mills on this as drilling 4 holes 4part depth in one shot perdect strait for LMUU
[12:08:13] <humble_sea_bass> if you're tapping the end, wouldn't a regular ol lathe manhandle that
[12:08:34] <CaptHindsight> http://www.productionmachining.com/articles/reducing-thrust-loads-during-rigid-tapping vs http://www.productionmachining.com/articles/rigid-tapping--sometimes-you-need-a-little-float
[12:08:56] <XXCoder2> humble some of 8020 exrusions is very long
[12:09:03] <XXCoder2> think largest size is 96"
[12:09:09] <IchGuckLive> going for 2 drill sizes one 3teeth precise drill and a rim
[12:09:17] <XXCoder2> maybe lathe with passthough chuck
[12:09:23] <humble_sea_bass> but what do you need a tap 100% thru for
[12:09:52] <syyl_ws> i bet they have kinda specialised cnc for that
[12:09:59] <syyl_ws> with one very long x-axis
[12:10:06] <syyl_ws> and a multible head for drilling/tapping
[12:10:29] <IchGuckLive> PetefromTn_: ive seen from the Universety exploretion on DEMAG a 6m Crane Drill press
[12:10:41] <syyl_ws> that even does the cutting
[12:10:47] <syyl_ws> to length
[12:11:10] <CaptHindsight> they cut with radial arm saws
[12:11:28] <syyl_ws> ah ok
[12:11:52] <humble_sea_bass> look at the load distribution for a nut
[12:12:16] <humble_sea_bass> the deeper it goes, the less load the thread sees
[12:12:22] <humble_sea_bass> there is an effective depth
[12:12:37] <humble_sea_bass> that after that, you're just splitting hairs
[12:13:29] <CaptHindsight> a few holes tapped by hand is fine or paying them for 10-100 but if you are going to tap thousands I was considering buy vs building a machine
[12:13:31] <humble_sea_bass> woop found the jam
[12:13:40] <humble_sea_bass> incoming pasta
[12:13:41] <humble_sea_bass> Caution: It appears that one could theoretically increase the thread strength by increasing the length
[12:13:44] <humble_sea_bass> of engagement. However, as illustrated in the Load Distribution chart above, the first thread will be
[12:13:47] <humble_sea_bass> taking the majority of the applied load. For carbon steel fasteners (including tapped holes) the
[12:13:50] <humble_sea_bass> length of engagement would be limited to approximately one nominal diameter (approximately 1-
[12:13:53] <humble_sea_bass> 1/2 times the diameter for aluminum). After that, there is no appreciable increase in strength. Once
[12:13:56] <humble_sea_bass> the applied load has exceeded the first thread’s capacity, it will fail and subsequently cause the
[12:13:59] <PetefromTn_> sweet
[12:14:00] <XXCoder2> holy paste hell
[12:14:52] <humble_sea_bass> remaining threads to fail in succession.
[12:14:52] <Jymmm> XXCoder2: Is that like Damned Swiss cheese?
[12:15:49] <humble_sea_bass> https://www.fastenal.com/content/feds/pdf/Article%20-%20Screw%20Threads%20Design.pdf
[12:16:02] <CaptHindsight> humble_sea_bass: there you go, spouting off with your facts and figure and critical thinking, can't you see I'm just looking for opinions? :)
[12:18:05] <IchGuckLive> CaptHindsight: did y<our cpompany got affected by the large earthquake
[12:18:53] <IchGuckLive> hi sylphiae
[12:19:14] <sylphiae> hi IchGuckLive
[12:20:13] <IchGuckLive> humble_sea_bass: pasta aldente ?
[12:22:06] <humble_sea_bass> fever dreams from machine design courses of years past
[12:22:14] <humble_sea_bass> years pasta
[12:26:05] <CaptHindsight> IchGuckLive: that was way on the other side
[12:27:23] <archivist> IchGuckLive, you wanted me?
[12:28:17] <IchGuckLive> archivist the BENT new guy here ased about 3D printer on rails
[12:28:47] <IchGuckLive> this night 3D printer work propper on Timingbelt an lmuu pin bearing
[12:29:12] <archivist> draw slides he was asking about for milling
[12:29:28] <IchGuckLive> the logs said 3D printing
[12:29:53] <ssi> syyl: VOLATILE_HOME setting in ini solves my problem entirely
[12:30:20] <syyl> then it unhomes it when the machine goes on disabled?
[12:30:39] <ssi> yep
[12:30:44] <syyl> cool :)
[12:30:55] <ssi> and since my teleop mode switch code is based on axes being homed, that also takes it out of teleop mode
[12:30:58] <ssi> so perfect
[12:32:29] <IchGuckLive> or Estop will also trigger VOLATILE_HOME
[12:33:10] <archivist> IchGuckLive, you did not read all his question then
[12:33:12] <archivist> <Bent> Hey guys, working on a mill/3d printer. NEMA 17's with 68oz-in, probably wood construction, shapeoko 2 like design, 300x300x200mm build volume. Want it to do aluminium. My question is about linear glides. I've seen some controversy about drawer slides, what is your opinion?
[12:33:53] <IchGuckLive> agree
[12:33:54] <archivist> you cannot only answer the bit you like
[12:34:34] <IchGuckLive> im getting old not long till im off here ;-)
[12:35:01] <CaptHindsight> " I've seen some controversy about drawer slides," sound engineering choices vs prayer and shoestring budget
[12:35:21] <XXCoder2> drawers probably just fine for cheap wood cnc
[12:35:45] <XXCoder2> I decided not to do those becasuse I want to try make my machine strong enough to mill alum
[12:36:17] <IchGuckLive> XXCoder2: will the mashine run at the end of this month
[12:36:31] <XXCoder2> would say yes if not pushing it and well greased
[12:37:51] <archivist> one could preload a pair if they were an engineered pair, but the normal bent stuff down the hardware store....yuck
[12:38:07] <XXCoder2> definitely very low end lol
[12:38:14] <ssi> honestly I'd rather use the shapeoko's rails than drawer slides
[12:38:47] <IchGuckLive> mashine Size VS Nema Size VS material VS partmat.
[12:38:52] <CaptHindsight> http://www.pbclinear.com/LPRR-Low-Profile-Redi-Rail-Linear-Guide
[12:39:18] <archivist> ex gov rails for 19" rack can be solid and machined
[12:39:30] <humble_sea_bass> the lawd jesus is by mah side and he will see mah shoestring budget through
[12:39:41] <XXCoder2> 'merica
[12:40:11] <ssi> CaptHindsight: hey check this out: https://pbs.twimg.com/media/BtKoW6hIIAATj61.jpg:large
[12:40:24] <ssi> CaptHindsight: any thoughts on how to make the lower tube (which controls focus height) into a Z axis?
[12:40:53] <CaptHindsight> http://www.pbclinear.com/LPM-Low-Profile-Mini-Rail-Linear-Guide precision drawer slide
[12:40:59] <ssi> I don't have a ton of room to work with, and might have to do it only on one side because the beam enters the other side
[12:42:57] <ssi> also, that pbc stuff looks handy, but "fill in a form for a quote" pretty much guarantees I'll never use them
[12:43:30] <ssi> cause that's code for "it's $1000 each or 1000 for $2000"
[12:43:55] <archivist> last time I filled a form in I never got a reply
[12:44:32] <ssi> igus is the same way, but I was at least able to buy some stuff from them
[12:44:55] <CaptHindsight> doesn't igus have an online store now for many parts?
[12:45:02] <ssi> yeah
[12:45:18] <ssi> but once you order from it, they sic the sales reps on you :)
[12:45:28] <ssi> although the sales reps sent me a big box of samples, so that was cool I guess
[12:45:41] <IchGuckLive> im off for today BYE
[12:48:03] <CaptHindsight> ssi: whats there to work with? is that knurled ring part of the tip?
[12:48:04] <archivist> I got the brochures and samples at a show
[12:48:23] <ssi> CaptHindsight: the knurled ring is a jam nut for the nozzle
[12:48:46] <ssi> the focus lens lives in the tube, the tube can slide up and down to change the focal height, and the nozzle can be adjusted on the tube to change the clearance from the end of the nozzle to the spot
[12:48:56] <ssi> right now it's about .350" from the end of the nozzle to the spot
[12:49:13] <ssi> I run into a lot of problems because plywood is miserably not flat
[12:49:21] <ssi> and cutting big pieces, my focus is all over the place
[12:49:31] <ssi> contemplating ways of making something like a THC
[12:49:40] <ssi> but it requires somehow giving the focus motion
[12:50:02] <CaptHindsight> we move the z while we track the surface
[12:50:32] <ssi> right, that's what I'm getting at
[12:50:37] <ssi> lemme put up a better pic
[12:50:39] <CaptHindsight> laser displacement sensor
[12:51:15] <ssi> sure... sensor part will have to happen, but it's useless without a way to move the lens
[12:51:24] <ssi> https://pbs.twimg.com/media/BuIYL4rIAAArx6b.jpg
[12:52:37] <ssi> I bet a head could be made which enclosed the focus in a voice coil actuator, but that's probably beyond the scope of my project
[12:53:10] <XXCoder2> Got stupid idea for ya ssi lol
[12:53:17] <ssi> i love stupid ideas
[12:53:38] <XXCoder2> control laser strength by voice. you could literally "record" noises as it moves across surface
[12:53:52] <ssi> :)
[12:54:25] <ssi> be better to write a kinematics module that controls motion normal to the path by sound
[12:54:29] <ssi> then you could cut a spiral
[12:54:38] <ssi> and it would wiggle the groove back and forth relative to amplitude of sound
[12:54:42] <ssi> and laser-cut a very crappy sounding record
[12:54:55] <XXCoder2> yeah but I was just thinking of neat effect not record
[12:55:06] <XXCoder2> thats why I put "record" in quotes
[12:58:32] <Jymmm> You are describing a $15 DVD-R drive btw.
[12:59:06] <XXCoder2> uh no
[12:59:29] <XXCoder2> dvd do not store noises that way
[13:10:56] <ssi> :P
[13:21:33] <Jymmm> XXCoder2: and your point is?
[13:21:53] <XXCoder2> Besides I wasnt one who menioned in spirl.
[13:21:57] <XXCoder2> ssi did
[13:22:21] <Jymmm> XXCoder2: goony goo goo
[13:22:31] <XXCoder2> Aww baby nice :)
[13:22:53] <Jymmm> I think you better google it =)
[13:23:07] <XXCoder2> wow baby knows google
[13:23:23] <Jymmm> XXCoder2: http://www.dailymotion.com/video/xgvyqk_eddie-murphy-goonie-goo-goo_fun
[13:23:31] <XXCoder2> its probably some nasty insult or whatever. dont care
[13:23:55] <Jymmm> pretty much.
[13:24:12] <Jymmm> funny shit though
[13:25:10] <XXCoder2> maybe but opendns apperently dont like that site. probably not captioned anyway
[13:25:55] <Jymmm> oh that's right, fogot.
[13:26:05] <Jymmm> forgot*
[13:26:16] <XXCoder2> nice save. ;) jk
[13:28:38] <Jymmm> XXCoder2: http://www.imdb.com/title/tt0085474/quotes
[13:28:51] <Jymmm> XXCoder2: read ALL the yellow part
[13:29:16] <Jymmm> err the 2nd section (long)
[13:29:29] <XXCoder2> lol yeah was wondering. :P
[13:29:56] <Jymmm> mouse over turns yellow, damn dev
[13:29:59] <XXCoder2> lol funny
[13:30:02] <XXCoder2> yeah
[13:30:15] <XXCoder2> some devs feel need to show their dev e-peen
[13:30:27] <XXCoder2> "looks it spins and changes colors as you mouseover!"
[13:30:35] <XXCoder2> "how is it useful?"
[13:30:41] <XXCoder2> "ohhhh YELLOW NOW!"
[14:14:09] <XXCoder2> wow
[14:14:10] <XXCoder2> http://www.scorchworks.com/Blog/auto-probing-with-g-code-ripper/
[14:35:48] <CaptHindsight> XXCoder2: .exe or .jar only, so who knows how accurate it is, how many samples it uses, what else it does etc etc
[14:36:38] <XXCoder2> it dont really have to be that accurate, it just adjusts cut so it will successfully "recreate" stock digitally for it to figure where to cut or npt
[14:37:15] <XXCoder2> or to alter where Z it cuts so nice logo can appear on courved mouse as it shows on video
[14:37:24] <CaptHindsight> if you don't want it to be that accurate
[14:37:31] <XXCoder2> I wouldnt depend on it to accurately recreate curve
[14:37:46] <CaptHindsight> your guess is as good as mine
[14:37:52] <XXCoder2> yeah
[14:39:03] <CaptHindsight> https://bitbucket.org/daedelus1982/autoleveller/src here;s the source cleverly hidden from the main page
[14:39:20] <XXCoder2> its not same
[14:39:28] <CaptHindsight> heh
[14:40:32] <XXCoder2> still, for a hack its pretty awesome
[14:40:52] <XXCoder2> I mean, its nice easy way to put logo on complex curved surface for example
[14:41:34] <CaptHindsight> have fun with it
[14:42:59] <XXCoder2> maybe will ry it, but not now. besides my first cnc will only has 3 inches clearance.
[14:43:13] <XXCoder2> not much room for curved parts lol
[14:46:05] <CaptHindsight> we usually start with the 3d model for the part and if we don't have that scan --> point cloud --> 3d model --> CAD, CAM --> G-code
[14:46:44] <XXCoder2> that is pretty lot of work if you just want engrave logo
[14:47:08] <XXCoder2> it has bonus of working on any curved surface - create logo flat surface then use this to place on anything
[14:47:37] <XXCoder2> baseball bat? sure? ball? sure. theres some limits sure but yeah
[14:50:10] <Tom_itx> there's more than one way to lay an image on a surface too
[14:50:26] <CaptHindsight> http://www.youtube.com/watch?v=ShuGBpYdFtk
[14:50:51] <XXCoder2> tom did you see my link?
[14:51:00] <Tom_itx> the mouse? yes
[14:51:19] <XXCoder2> yeah has baseball bat too.
[14:51:38] <XXCoder2> that is awesome. done by same software I see
[14:51:58] <CaptHindsight> you could use that print hot melt on non-planar surfaces as well
[14:52:07] <CaptHindsight> to print
[14:52:22] <XXCoder2> thats nice too. wonder if creator know
[14:52:33] <Tom_itx> mine will do a wrap, projected or follow the contour
[14:52:59] <XXCoder2> print on spheric surface to have initial curve without having to build supporting pastic
[14:53:06] <CaptHindsight> don't tell anyone of there will be a kickstarter of how they use a glue gun to decorate non-planar parts
[14:55:12] <CaptHindsight> but then they'll need a 5-axis glue gun
[14:55:55] <XXCoder2> as long as it does not hit surface with wrong part of glue gun head, I wouldnt think its a big issue.
[14:57:42] <CaptHindsight> maybe a glue gun lathe for printing on tubes and bats
[14:58:11] <CaptHindsight> tubes are easy since you're just wrapping a plane around an axis
[14:59:00] <CaptHindsight> thats it, I'll change the world!
[14:59:23] <XXCoder2> lol
[14:59:29] <XXCoder2> kickstart it
[14:59:34] <CaptHindsight> and yes, it may be controlled from smartphone or tablet while at the beach
[14:59:48] <XXCoder2> it can make gold out of lead too
[15:09:09] <XXCoder2> would be funny if we somehow found a way to turn lead to gold
[15:20:30] <kfoltman> any advice on machining extruded acrylic?
[15:20:34] <kfoltman> (other than "don't")
[15:22:10] <jdh> sharp bits
[15:22:49] <Deejay> hehe
[15:30:59] <SpeedEvil> Use yak-blood as coolant
[15:32:34] <kfoltman> SpeedEvil: liquid helium, probably ;)
[15:36:02] <PetefromTn_> https://www.youtube.com/watch?v=Bu535PZzysE#aid=P-M1jO-Ol2s This is simply awesome!
[15:43:55] <jsskangas> those guys must have couple of rivets losen...
[15:45:06] <jsskangas> Does anyone know about TCP in non rotatingtable mode???
[15:45:33] <jsskangas> I have done mathematics for rotating table mode
[15:46:11] <jsskangas> but I need to implement G43.4 (fanuc code) to my linuxcnc
[16:18:20] <XXCoder2> looking
[16:20:59] <XXCoder2> PetefromTn_: insane flying
[16:22:49] <XXCoder2> PetefromTn_: https://www.youtube.com/watch?v=as82OA_GtnA
[16:33:29] <PetefromTn_> yeah man that is just NUTZ.
[16:33:46] <XXCoder2> yeah grinding wings man
[16:33:54] <PetefromTn_> I have never seen a plane hover sideways like that for so long and so stable that close to the ground.
[16:34:18] <PetefromTn_> that pilot has massively huge gorilla balls...
[16:34:42] <XXCoder2> yeah wonder how plane flew with such huge steel spheres in it
[16:34:57] <PetefromTn_> bronze man....bronze!
[16:35:05] <PetefromTn_> ;)
[16:35:17] <XXCoder2> probably swapped for lighter titanium balls lol
[16:35:31] <PetefromTn_> I've done some crazy shit in my life but never anything like that.
[16:36:03] <XXCoder2> lol well
[16:36:58] <PetefromTn_> I guess at some point the stuff is so damn dangerous already what is a little more crazy gonna do really.
[16:42:26] <XXCoder2> guess so
[16:48:01] <Deejay> gn8
[17:28:02] <tjtr33> CaptHindsight, https://www.youtube.com/watch?v=Dd_M6Li_OrA horz tapping head
[17:28:41] <XXCoder2> tjtr33: nice
[17:32:19] <tjtr33> maybe of use http://goo.gl/QqRJfj
[17:34:27] <tjtr33> i picture a box opening as big as 8030 , like a pencil sharpener, stick in random 8020 lenght and it taps the ctr hole for you
[17:37:06] <tjtr33> bbl
[18:10:55] <asah> having a quadrature reading issue on a mesa 7i52
[18:11:25] <asah> the encoder is a parker, differential output quadrature.
[18:12:13] <asah> on my scope I can see quadrature on each A and B channel when I go between the two differential pair legs (A -> A*)
[18:12:50] <MrHindsight> tjtr33, it doesn't even have to drill since they extrude the holes ready to be tapped
[18:13:10] <asah> so that seems all good, but when I open up linuxcnc I am getting no counter movement on the encoder.
[18:13:40] <asah> this setup was just working for two other motors (fanuc red caps) today, unplugged those, plugged in the parker and now no movement.
[18:14:19] <MrHindsight> tjtr33, maybe dedicate an old spare bridgeport or similar to this task
[18:16:13] <asah> I have swapped between the ttl mode and non and no dice.
[18:16:36] <MrHindsight> http://www.blackalloy.com/taphead.htm
[18:33:42] <PetefromTn_> Damn I finally got the kitchen sink installed and plumbed up and our new counter tops and everything done. Jeez I am slow as hell LOL
[18:35:16] <XXCoder2> my new drill press. https://i.chzbgr.com/maxW500/4214470912/hF75BB497/
[18:35:28] * LeelooMinai looks sadly at torn floor and all cabinets in the kitchen
[18:35:42] <PetefromTn_> jeez man you need to ante up for some better tools LOL
[18:35:48] <XXCoder2> lol
[18:36:01] <PetefromTn_> LeelooMinai It's okay man don't feel bad It took me almost six years to get this far hehehe
[18:36:04] <LeelooMinai> That's a pretty MacGyver drill press there
[18:36:12] <XXCoder2> my actual drill press is chinese crap from fright harbor
[18:36:27] <PetefromTn_> would probably work better than that contraption...
[18:36:39] <XXCoder2> yeah
[18:37:14] <PetefromTn_> Dacia is making some fajitas and black bean soup and DAMN it smells good right now LOL
[18:37:29] <PetefromTn_> I must be hungry.
[18:37:33] <LeelooMinai> It's ok - I need my mom to feel happy about her house. And I have a lot of experience building kitchen cabinets from plywood... o, wait, I don't.
[18:37:57] <PetefromTn_> I must have built thousands of custom cabinets by now.
[18:38:22] <PetefromTn_> every flavor under the rainbow.
[18:38:44] <PetefromTn_> you would think getting my own damn kitchen finished would be a slam dunk right...
[18:39:18] <LeelooMinai> My main goil is for the cabinet not to topple over when done
[18:39:22] <LeelooMinai> goal
[18:39:29] <PetefromTn_> I hear ya.
[18:39:31] <XXCoder2> good solid plan lol
[18:39:41] <PetefromTn_> gotta have priorities..
[18:40:47] <PetefromTn_> these are getting a five stage finish with glaze and clear etc so it takes a bit longer but that is NO excuse for how long it has taken for sure. My wife sure is happy the sink is back tho hehehe
[18:46:42] <XXCoder2> cool
[18:47:44] <MrCurious> wonder if marlin would be viable to drive a cnc machine
[18:49:35] <pcw_home> asah: you may have A , *B and *A , B pairs
[18:50:35] <pcw_home> also if you are running 2.6 or master you can look at the A/B encoder lines in HAL
[18:53:22] <asah> I do have A and A* and B and B* pairs. are you thinking I need to pair A->B and A* -> B* ???
[18:53:33] <asah> I think I am running master over here.
[18:53:47] <asah> where is A/B separate avail in hal?
[18:55:23] <pcw_home> The way to check the wiring is connect a DVM _across_ A and *A and B and *B
[18:55:57] <asah> dvm or a scope?
[18:56:10] <pcw_home> DVM is fine
[18:56:28] <asah> like twist A with A* and check that relative to B twisted with B* ?? seems weird.
[18:57:16] <asah> ok I think I see what yo uare saying. that I should just do connectivity to determine the pairs if I have them messed up.
[18:57:32] <pcw_home> No its just a common wiring mistake with diff encoders to have a A matched with B
[18:58:34] <asah> and I am looking for voltage?
[18:58:37] <asah> (none found)
[18:58:56] <pcw_home> if you measure across A and *A you should measure ~ 3V or ~ -3V but never 0
[18:59:39] <pcw_home> (as you wiggle the encoder shaft around to see the various states)
[18:59:53] <pcw_home> likewise for B
[19:01:53] <pcw_home> I think I went through this on a forum post
[19:01:55] <pcw_home> for differential encoders with index, and assuming the
[19:01:56] <pcw_home> power is wired correctly, there are 720 possible wirings
[19:01:58] <pcw_home> of which only 48 work
[19:02:04] <ssi> ha
[19:02:16] <asah> oh lovely.
[19:02:24] <ssi> 6 factorial :P
[19:02:41] <ssi> except I'm not sure if that's exactly correct combinatorics
[19:03:39] <ssi> isn't it like k!/(k-n)!n! or something like that?
[19:03:43] <ssi> my combinatorics escapes me :)
[19:03:44] <pcw_home> I'm pretty sure thats right
[19:04:55] <ssi> yea you're right, nm: )
[19:06:20] <pcw_home> most of the funny connections count 1,0,1,0, or similar or once/turns for index / AB swaps
[19:07:36] <pcw_home> the A/B pins are part of the encoder now (In 2.6 and master) so you can just halscope/halmeter them
[19:12:14] <asah> really weird…
[19:12:27] <asah> I can see it on the scope, but not on either of my two dvms
[19:14:31] <ssi> are you trying to dvm it while it's spinning?
[19:14:44] <asah> yes.
[19:14:47] <ssi> if so I imagine it'd average out to 0 :)
[19:14:55] <asah> but really slow.
[19:15:21] <asah> I am certainly seeing an A and a B quadrature signal.
[19:15:34] <asah> they are 90 degrees from each other on the scope.
[19:21:40] <MrHindsight> MrCurious, is that a reprap board? have a link?
[19:23:03] <MrCurious> https://github.com/ErikZalm/Marlin
[19:23:35] <MrCurious> but i think i will change from a parallel port based driver for my cnc to a http://shop.uberclock.com/collections/smoothie/products/smoothieboard
[19:28:35] <asah> pulling master now.
[19:39:59] <MrHindsight> MrCurious, those are all reprap class boards that don't work with Linuxcnc
[19:40:25] <MrCurious> yeah, they eliminate the need for emc
[19:40:32] <MrCurious> as they run the g code themselves
[19:41:08] <MrCurious> that whole has to have a parallel port is not an ideal solution in the modern world where parallel ports are super rare
[19:42:53] <MrHindsight> MrCurious, you might want to visit #reprap
[19:47:04] <asah> looks like it was encoder power related.
[19:47:16] <asah> fixed now! thanks peter
[19:49:00] <ssi> MrHindsight: the controller board that they're using for that pnp
[19:49:11] <ssi> MrHindsight: I talked to those guys at maker... they have a finite jerk TP for it
[19:49:16] <ssi> I wonder if we could appropriate their TP :P
[19:52:50] <MrHindsight> ssi, smmooothie or marlin?
[19:54:02] <ssi> no... what was it called
[19:54:04] <ssi> you linked it to me
[19:54:24] <ssi> it's a four axis all in one controller board with drivers
[19:54:36] <ssi> that they're using for that open pick and place project you've been talking about
[19:54:48] <MrHindsight> oh I forget the name
[19:56:08] <MrHindsight> the OpenCV work might be of use if they did it right
[20:10:54] <tjtr33> why are many very large stone routers like this: , gantry moves, table fixed ( stone is heavy ) BUT the gantry is a wide X Z moving on short Y rails
[20:11:25] <tjtr33> (tjtr33 needs a big machine tool for a project and was looking at alternatives)
[20:19:36] <tjtr33> heh this one is not long x short y, and is very big http://www.machines4sale.com/machines4sale/msimages/newsimages/20140224_00002742.jpg
[20:22:08] <tjtr33> haha they call the long axis X ( hard to tell when operator pendant is inside the work envelope, and the parts load at ends of Y , so photo is sideways )
[20:38:49] <CaptHindsight> tjtr33: http://d2n4wb9orp1vta.cloudfront.net/resources/images/cdn/cms/MMS_0410_Windustries_A.jpg
[20:40:09] <tjtr33> thats the ticket! no need to lower your expectations ( outside of accuracy over 20 meters is likely a few cm :)
[20:40:51] <CaptHindsight> tjtr33: for EDM?
[20:41:18] <CaptHindsight> http://www.coord3-cmm.com/used-gantry-coordinate-measuring-machine/ this might work
[20:42:00] <tjtr33> yah, why not, these big machines theyu just pee on the big automotive molds, so the table weight is huge. moving gantry seems ideal
[20:42:32] <CaptHindsight> http://www.coord3-cmm.com/wp-content/uploads/2013/04/MCT-StarLight-2-Gantry-1024x821.jpg
[20:42:32] <tjtr33> well cmms are not very stiff, but those mills would be
[20:43:09] <tjtr33> no way! jack screws!!
[20:44:05] <CaptHindsight> is it for milling?
[20:45:21] <tjtr33> no, sink edm, need 2 heads 5 meters travel total, 1.5Y and 1 Z. the casting has become a huge problem, actually storing the cores AND handling the machine base is trh eprob. not enuf floor space in the factory :)
[20:46:19] <tjtr33> save a bundle if that machine didnt have to come from asia, only the electrics
[20:47:17] <tjtr33> btw edms are stiff machines, like hsm's
[20:47:49] <tjtr33> oh well gotta pack ( happy happy got some work :)
[20:47:52] <tjtr33> bye!
[20:55:44] <PetefromTn_Andro> beautiful evening folks
[20:56:13] <PetefromTn_Andro> here in the east of Tennessee
[20:57:28] <humble_sea_bass> you're the only ten-i-see
[20:57:49] <PetefromTn_Andro> oh I'm a ten now LOL
[20:58:06] <PetefromTn_Andro> I'm usually an
[20:58:13] <PetefromTn_Andro> six...
[20:58:38] <PetefromTn_Andro> whaddya doing man?
[20:58:56] <humble_sea_bass> doing drugs mostly
[20:59:18] <PetefromTn_Andro> aah chemical alternatives
[21:00:45] <PetefromTn_Andro> I worked on my spindle encoder mount program some more this evening.
[21:01:12] <PetefromTn_Andro> I need to get it done so I can rigid tap financial
[21:01:20] <PetefromTn_Andro> finally
[21:01:44] <humble_sea_bass> what encoder did you get
[21:03:10] <PetefromTn_Andro> I cannot remember the manufacturer of it right offhand
[21:03:26] <PetefromTn_Andro> abeco or something like that
[21:03:32] <jdh> is that being held by an alien?
[21:03:56] <PetefromTn_Andro> huh?
[21:04:05] <jdh> <oops>
[21:04:54] <PetefromTn_Andro> enjoying some Pink Floyd Division bell on my studio monitor headphones ....
[21:05:10] <PetefromTn_Andro> Damn I love this album.
[21:05:36] <jdh> even without weed?
[21:06:04] <PetefromTn_Andro> yup even without weed....awesome mellow out music
[21:06:16] <jdh> waterless pink
[21:06:58] <PetefromTn_Andro> apparently they are going to release a new Floyd album next year or something like that.
[21:07:41] <PetefromTn_Andro> I think that encoder is an avago technologies model.
[21:08:02] <PetefromTn_Andro> 500 line I think.
[21:08:57] <PetefromTn_Andro> I borrowed an MA FORD 1"x90 degree champfer bit from a guy zip used to work with this weekend.
[21:09:20] <PetefromTn_Andro> he dropped it by and I showed him my CNC mill.
[21:09:41] <PetefromTn_Andro> He could not believe I run it entirely off single phase.
[21:09:53] <PetefromTn_Andro> I had to prove it to him LOL.
[21:10:27] <jdh> https://www.facebook.com/photo.php?v=10152401910323409
[21:10:39] <PetefromTn_Andro> He seemed pretty impressed with it. We ran a short program made for the HAAS machines he uses at work he had on a thumb drive.
[21:10:40] <humble_sea_bass> you run your shop off single phase?
[21:10:59] <humble_sea_bass> whaaaa
[21:11:28] <PetefromTn_Andro> to my surprise it ran almost without issue.
[21:11:43] <PetefromTn_Andro> yup entirely single phase.
[21:12:17] <PetefromTn_Andro> Got rid of the phase converter I had and switched to all new servos and drives
[21:13:10] <humble_sea_bass> on the cinci?
[21:13:22] <PetefromTn_Andro> whenever I manage to get a CNC slant bed lathe I plan to try to do the same thing with it.
[21:13:32] <PetefromTn_Andro> yeah Cincinnati arrow 500
[21:14:39] <PetefromTn_Andro> I was worried my power bills would be high but so far even on the heaviest usage months I have hardly noticed a change at all.
[21:15:14] <humble_sea_bass> yeah the amp draw could be bananas
[21:15:15] <PetefromTn_Andro> If I can get a large production run in here at some point that may change
[21:15:35] <PetefromTn_Andro> I run the whole machine off a 60 amp breaker.
[21:15:48] <PetefromTn_Andro> never tripped it once so far
[21:16:52] <ssi> peet
[21:16:52] <humble_sea_bass> that's actually really reassuring
[21:17:34] <PetefromTn_Andro> sup ssi
[21:17:56] <PetefromTn_Andro> yeah I am very pleased with the machine so far. It just plain works.
[21:19:12] <PetefromTn_Andro> I finished the prototype I was working on this weekend and machines some more custom scope riser rails. Got several more to do but I gotta empty my chip trays out they are freaking full LOL
[21:19:44] <humble_sea_bass> do you recycle your chips and swarf
[21:20:28] <PetefromTn_Andro> honestly so far I have not but I want to. I have only been milling 6061 so it is all the same stuff. should not have any issues recycling it.
[21:21:27] <PetefromTn_Andro> I love this song wearing the inside out on Division Bell
[21:22:00] <PetefromTn_Andro> humble you work in a pro shop right?
[21:22:28] <XXCoder2> I wonder if theres some point where it is worth it to remelt swar into more sheets
[21:22:36] <XXCoder2> or blocks or whatever
[21:22:54] <PetefromTn_Andro> I doubt it would be worth the trouble.
[21:23:14] <humble_sea_bass> well, if it isn't a hassle for you and collecting it isnt a pain in the ass
[21:23:19] <PetefromTn_Andro> unless you just get off on the idea of doing it.
[21:23:50] <XXCoder2> well probably cheaper than buying similiar size stock if dont mind bit lower quality
[21:24:07] <PetefromTn_Andro> actually my machine has slide out pans on each side and they just get scooped out pretty easy really.
[21:24:32] <humble_sea_bass> if i had a small cinter jam,
[21:24:44] <PetefromTn_Andro> I just need to figure out who to give it to locally
[21:25:22] <PetefromTn_Andro> whazza cinter jam?
[21:27:08] <PetefromTn_Andro> I have been looking at some videos online that show these multi axis work stops
[21:27:16] <humble_sea_bass> https://www.youtube.com/watch?v=SDyi3L86i00
[21:27:25] <PetefromTn_Andro> many are shop built and look sweet.
[21:27:27] <humble_sea_bass> brickette maker
[21:27:29] <humble_sea_bass> hah
[21:28:08] <asah> what is your mill PetefromTn_Andro?
[21:28:17] <asah> I am doing a single phase conversion on my maho MH400
[21:28:28] <PetefromTn_Andro> I am sure I could machine the base and body of the thing and the rest is simple lathe work.
[21:28:37] <XXCoder2> reminds me of that machine that turns wood swarf into thin "logs" for wood burning
[21:29:06] <PetefromTn_Andro> asah my mill is a Cincinnati Arrow 500 VMC
[21:29:16] <asah> just got all my new servos spinning today!
[21:29:34] <PetefromTn_Andro> awesome its a great feeling huh.
[21:29:58] <PetefromTn_Andro> did you gut the pig like I did and start with all new servos and drives?
[21:30:17] <asah> yeah.
[21:30:24] <PetefromTn_Andro> nice
[21:30:30] <asah> scored a bunch of fanuc redcaps from ebay.
[21:30:44] <asah> using mesa 8i20s to drive them.
[21:31:10] <PetefromTn_Andro> yup mesa rocks.. I am using the 5i25/7i77 combo
[21:31:12] <asah> am just about to mount the first axis! pretty fun.
[21:31:58] <asah> thats smart, I went with way more boards.
[21:31:59] <PetefromTn_Andro> except for my screwing up and frying some stuff I have had zero trouble with my mesa stuff.
[21:32:14] <asah> but my boards started off life on another project.
[21:32:24] <asah> I am mostly all good except for 5v IO.
[21:32:31] <asah> might need to get another board for that.
[21:32:40] <asah> but peter is great.
[21:32:44] <PetefromTn_Andro> why 5 volt?
[21:33:13] <asah> I could hook up the commutation tracks from the encoders.
[21:33:26] <asah> Ill get there, but currently just going to go with wake and shake.
[21:33:40] <PetefromTn_Andro> sweet.
[21:33:44] <asah> bldc qi
[21:33:58] <PetefromTn_Andro> post a video when you get it running so we can see that monster.
[21:34:10] <asah> =) its a smaller monster than yours.
[21:34:21] <asah> my wife would kill me if I had that out in my shop.
[21:34:23] <asah> =)
[21:34:39] <PetefromTn_Andro> heh mines not all that big really
[21:35:00] <PetefromTn_Andro> it's like 9' square
[21:35:09] <asah> prob another third on each axis from me.
[21:35:25] <PetefromTn_Andro> its 20x20x20 actually
[21:35:39] <PetefromTn_Andro> 500mm
[21:36:06] <asah> yeah, a bit bigger than me. excited to get this thing back up.
[21:36:27] <PetefromTn_Andro> I am sure.
[21:36:35] <asah> had it up under philips control (circa 1986) and it was super painful.
[21:36:45] <PetefromTn_Andro> those are supposed to be really high quality machines
[21:37:36] <asah> it looks really nice. glass scales, nice horizontal to vertical mill changero options, cat40 hydraulics etc...
[21:37:41] <asah> no toolchanger on the 400 though.
[21:37:42] <asah> =(
[21:38:10] <PetefromTn_Andro> I would love to have a horizontal/vertical machine like that
[21:38:16] <asah> if I get rid of the cab / make it a separate unit it would basically be a smaller footprint than a bridgeport.
[21:38:31] <asah> maybe we trade when we are bored. =)
[21:38:41] <PetefromTn_Andro> hehehe
[21:38:51] <asah> freight from cali would be rough =)
[21:39:07] <PetefromTn_Andro> I bet it will run circles around a bridgie
[21:39:25] <skunkworks> asah: you have the build log going on practical machinist..
[21:39:41] <asah> yeah.
[21:39:53] <asah> finally getting to the single phase phase.
[21:41:09] <asah> had to get some brackets and sprockets machined for the new servos. always frustrating to have to pay someone else to make something for the machine that can make it. =)
[21:41:12] <ssi> PetefromTn_Andro: I run my hnc on single phase too
[21:41:28] <ssi> I have two VFDs in it, one for the spindle motor and one for the coolant pump
[21:41:32] <ssi> everything else is 220 single phase
[21:41:43] <PetefromTn_Andro> yup that's what I have too
[21:41:54] <ssi> PetefromTn_Andro: I found a vmc I want to try to get
[21:42:03] <PetefromTn_Andro> so damn simple really
[21:42:08] <asah> that is something I have to do, I have a couple of vfds here on the shelf, one for spindle, one for the hydraulics.
[21:42:25] <PetefromTn_Andro> awesome what kind is it?
[21:42:31] <asah> after I can jog some axes, I hop on to that.
[21:44:46] <asah> here is the thread skunkworks was talking about, has some pics http://www.practicalmachinist.com/vb/dmg-mori-gildemeister-maho-cnc/maho-mh400e-retrofit-linuxcnc-277268/
[21:47:14] <PetefromTn_Andro> cool I'll check it out.
[21:50:57] <skunkworks> asah: akb1212 seems to over analyse everything...
[21:52:01] <asah> oh man… the longest posts ever!
[21:52:21] <skunkworks> heh
[21:52:24] <asah> he must be able to type really fast to get all that out. =)
[21:52:55] <asah> sounds like he has a nice machine.
[21:53:19] <asah> but yeah, he is a deep diver on every little detail.
[21:54:16] <PetefromTn_Andro> http://www.roviproducts.com/Mill_Stop.htm
[21:54:33] <PetefromTn_Andro> I want to make something like that for the CNC
[21:54:59] <asah> those are pretty nice. I have a knockoff.
[21:55:14] <PetefromTn_Andro> did you make it?
[21:55:23] <asah> ebay I think.
[21:55:46] <os1r1s> PetefromTn_Andro: If you make a small one, I'll buy it from you
[21:55:46] <PetefromTn_Andro> how do you like it?
[21:56:17] <asah> it cool. nice positive locking, I was surprised at how well it holds position.
[21:56:26] <PetefromTn_Andro> Honestly I will probably make one so I could make two just as easily LOL
[21:57:02] <os1r1s> PetefromTn_Andro: I need a smaller one though, which is what I can't find anywhere
[21:57:11] <asah> I got the idea from http://www.micro-machine-shop.com which has all kinds of nice little ideas.
[21:57:19] <PetefromTn_Andro> dunno how small it would be tho it needs to be able to reach my Kurt from a couple tee slots away easily.
[21:57:55] <os1r1s> PetefromTn_Andro: I just need it to work with a 10-32 t-nut
[21:58:19] <os1r1s> So the bottom piece is probably the only thing that would need to be different
[21:58:40] <PetefromTn_Andro> 10-32? jeez man that is small... I think mine are 1/2-13 or something
[21:59:50] <PetefromTn_Andro> what kinda mill do you have?
[22:00:04] <Tom_itx> taig or sherline probably
[22:00:06] <os1r1s> PetefromTn_Andro: taig
[22:00:09] <Tom_itx> :)
[22:00:12] <os1r1s> :)
[22:00:21] <PetefromTn_Andro> aah okay.
[22:00:29] <Tom_itx> those use 10-32
[22:00:52] <skunkworks> for low quantitity stuff I just probe the edges..
[22:01:05] <skunkworks> slap it in the vice - probe location..
[22:01:16] <PetefromTn_Andro> I bet if I made a nice small one like that in batches folks would buy them pretty good it does not seem like there are any for that size machine
[22:01:39] <os1r1s> skunkworks: I am milling injection molds, and I want to be able to drop it back in if I need to touch it up.
[22:01:57] <os1r1s> PetefromTn_Andro: There are none. I've looked everywhere
[22:01:58] <Tom_itx> from aluminum or steel?
[22:02:16] <os1r1s> Tom_itx: alum
[22:02:23] <Tom_itx> must be small molds
[22:02:24] <PetefromTn_Andro> yeah a nice quality table mounted vise stop is sweet to have even if you are just making a couple pieces
[22:02:43] <os1r1s> Tom_itx: Yeah. For a small IM machine.
[22:02:51] <Tom_itx> PetefromTn_Andro, problem is, i never use my table
[22:03:07] <Tom_itx> it's always got a plate on it
[22:03:21] <PetefromTn_Andro> yeah I know you use a spindle mounted work stop
[22:03:41] <Tom_itx> not on the sherline but on the big ones we did
[22:03:44] * skunkworks doesn't know how he ever did anything without a touch probe... ;)
[22:03:50] <Tom_itx> i may have a couple times...
[22:03:53] <PetefromTn_Andro> you can screw it to the plate probably
[22:04:02] <Tom_itx> yep, i made a crude one for a job
[22:04:17] <Tom_itx> with a slide mount to fit between the grid
[22:04:32] <PetefromTn_Andro> a spindle probe is on the to do list LOL
[22:04:51] <asah> ebay option: http://www.ebay.com/itm/Vise-stop-5-Axis-movement-mill-work-stop-part-locator-1-2-13-table-bolt-/121164910130?pt=BI_Tool_Work_Holding&hash=item1c35fdce32
[22:04:59] <Tom_itx> i made one but not with the accuracy of a _real_ one
[22:05:00] <PetefromTn_Andro> probably retrofit a commercial one
[22:05:48] <PetefromTn_Andro> damn that's not a bad price really.
[22:06:05] <PetefromTn_Andro> wonder of its a piece of shit or not?
[22:06:37] <asah> this one looks nicer than the one I have from ebay, which is more like :http://www.ebay.com/itm/5-Axis-Vise-Mill-Stop-Fits-Bridgeport-5-8-Table-Vises-/311031565847?pt=BI_Tool_Work_Holding&hash=item486aed0e17
[22:06:46] <asah> and that one is pretty positive.
[22:07:01] <asah> you could always modify it to suit after you got it. =)
[22:07:10] <asah> save you some cad time
[22:07:24] <PetefromTn_Andro> jeez man for $65.00 it is almost not worth the trouble to make one.
[22:07:44] <Tom_itx> depends how many you plan to make
[22:08:13] <PetefromTn_Andro> that guy Tom from OX tools on YouTube made one and he shows it in one of his videos..
[22:09:16] <PetefromTn_Andro> LOL yeah right. If I had folks interested I would machine a damn back scratcher If I thought I could make some decent cash on it LOL
[22:09:45] <PetefromTn_Andro> nose hair picker
[22:10:19] <Tom_itx> http://www.a2zcnc.com/
[22:10:21] <PetefromTn_Andro> butt scratcher with bonus extended finger heheb
[22:10:30] <Tom_itx> they make a few taig and sherline things
[22:11:12] <os1r1s> Tom_itx: littlemachineshop would probably buy a bunch of someone made them
[22:11:29] <os1r1s> They resell stuff others make I believe.
[22:11:48] <Tom_itx> they likely wanna make most of the profits though
[22:12:12] <os1r1s> I think selling direct is ideal. But if you didn't want to bother, I'm sure you could offload a ton there
[22:13:26] <PetefromTn_Andro> well I gotta get to bed kids start school tomorrow morning and I gotta get em there in time LOL
[22:13:40] <PetefromTn_Andro> nite all
[22:14:07] <Tom_itx> later
[22:14:23] <PetefromTn_Andro> cya Tom ;)
[22:16:12] <asah> later pete
[22:20:09] <ssi> I saw a guy with a little IM machine at maker, was pretty cool
[22:20:15] <ssi> I wouldn't mind playing with IM sometime
[22:23:41] <Jymmm> IM machine?
[22:31:22] <ssi> injection molding
[22:38:54] <CaptHindsight> I'd expect low pressure injection molding to be more popular for DIY
[22:39:36] <CaptHindsight> the same hot melts may be used for FDM
[22:42:07] <os1r1s> This is the IM I'm using ... https://www.dropbox.com/s/55eie4v96d0i66c/IM150B.jpg
[22:44:32] <Jymmm> red handle to hold the mold in place?
[22:44:59] <os1r1s> Jymmm: Its a quick clamp to hold it. It comes with a normal low profile vise
[22:45:06] <os1r1s> But I like that better
[22:45:39] <Jymmm> os1r1s: What are you molding typically?
[22:46:09] <os1r1s> Jymmm: I'm just getting started with it. But I want to use it to do small electronic cases and trinkets for my kids.
[22:46:26] <Jymmm> os1r1s: ah
[22:46:34] <os1r1s> Jymmm: I lasercut a ton of cases now, and would like something a bit quicker/easier.
[22:46:52] <Jymmm> acrylic?
[22:46:59] <os1r1s> Jymmm: Yeah
[22:47:38] <Jymmm> os1r1s: Are you laser cutting acrylic then solvent welding them ?
[22:49:57] <os1r1s> Jymmm: These ... http://store.gadgetfactory.net/acrylic-case-by-os1r1s-papilio-pro/
[23:02:32] <Jymmm> os1r1s: Ah
