[03:47:58] <Deejay> re
[06:20:17] <jthornton> morning
[06:31:34] <Jymmmm> jthornton: Ug
[06:33:37] <kfoltman> is there any generator to create gcode for making provisional rack and pinion?
[06:35:15] <kfoltman> nevermind: http://hessmer.org/gears/InvoluteSpurGearBuilder.html
[06:48:53] <Loetmichel> i would have suggested https://woodgears.ca/gear_cutting/template.html
[06:49:10] <Loetmichel> that can do rack an pinion, involute, even chains
[06:49:16] <Loetmichel> in the download version
[06:50:51] <SpeedEvil> The free version does comedy gears :)
[06:51:39] <Loetmichel> i made this with it: http://www.cyrom.org/palbum/main.php?g2_itemId=11714
[06:51:43] <Loetmichel> works perfectly
[06:52:00] <SpeedEvil> What are they?
[06:52:02] <SpeedEvil> - material
[06:52:04] <Loetmichel> (had to do it three times to get it backlash-less though) ;)
[06:52:26] <Loetmichel> resin-infused paper, 1/8" thick
[06:52:35] <Loetmichel> a.k.a "Pertinax"
[06:52:58] <SpeedEvil> LASER?
[06:53:02] <Loetmichel> milled
[06:53:13] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=11711
[06:53:18] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=11702
[06:53:28] <Loetmichel> 0.8mm 2 flute mill bit
[06:53:33] <SpeedEvil> Teeny bit is teeny
[06:54:01] <Jymmmm> Loetmichel: Find a girl with split ends that sues a LOT of hairspray
[06:54:08] <Jymmmm> uses*
[06:54:16] <Loetmichel> ?
[06:54:31] <Jymmmm> Loetmichel: Loetmichel: 0.8mm 2 flute mill bit
[06:54:50] <Loetmichel> still dont get ist
[06:54:53] <Loetmichel> it
[06:55:10] <Jymmmm> Loetmichel: Loetmichel: 0.8mm 2 flute mill bit --> Loetmichel: Find a girl with split ends that sues a LOT of hairspray
[06:57:09] <Loetmichel> still dont get it
[06:57:23] <Jymmmm> http://naturalmollire.com/wp-content/uploads/2011/11/2.png
[06:57:39] <Loetmichel> ah
[06:57:41] <Loetmichel> hrhr
[06:57:53] <Loetmichel> i even have 0,4mm 2 flute bits ;-)
[06:58:15] <Jymmmm> for?
[06:58:19] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=11933
[06:58:25] <Loetmichel> for milling small parts ,-)
[06:58:42] <Jymmmm> like?
[06:58:55] <Loetmichel> spmall clockwork geears for example
[06:58:56] <SpeedEvil> gears would be a great exampel
[06:59:07] <Jymmmm> ah
[06:59:20] <Loetmichel> they have not enough cutting depth for the 6mm pertinax, though
[06:59:34] <SpeedEvil> Well, flip over...
[07:00:40] <Loetmichel> i've used a siamond disc to do this: http://www.cyrom.org/palbum/main.php?g2_itemId=14403
[07:01:04] <Loetmichel> ... but i doubt my hands would be steady enough to do it with a 0,4mm bit ;-)
[07:01:13] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=14451
[07:02:03] <Loetmichel> diamond
[07:02:15] <Loetmichel> these mill bits are tungsten carbide, of course ;-)
[07:14:54] <kfoltman> Loetmichel: thanks, bookmarked
[07:17:07] <kfoltman> SpeedEvil: flip over and *align*, good luck with that :P
[07:17:29] <kfoltman> besides, 0.8mm bit is not THAT tiny
[07:17:58] <kfoltman> SpeedEvil: http://i.imgur.com/KCZ0y72.jpg that's with 0.8mm
[07:19:04] <kfoltman> Loetmichel: sharpening a 0.8mm endmill handheld? wow
[07:25:10] <SpeedEvil> kfoltman: well, three holes...
[07:37:29] <kfoltman> (hmm, it doesn't look like sharpening, grinding a 0.8mm bit from a 2mm bit? or?)
[07:42:13] <ssi> jthornton: morn
[07:42:30] <jthornton> morning
[07:42:58] <Loetmichel> kfoltman: grinding down the shaft for deeper cuts
[07:43:13] <kfoltman> ahhhh
[07:43:19] <Loetmichel> as i said:i doubt that will work freehand with a 0.4 bit
[07:43:54] <kfoltman> if at all - it might make the bit too brittle
[07:43:58] <ssi> jthornton: I dunno if you saw my msg from last night, but I brought home two 55gal plastic barrels AND a 40 gal water heater last nighT: )
[07:43:58] <Loetmichel> <. has kind of a tremor sometimes
[07:44:39] <Jymmmm> ssi: Goin off grid huh?
[07:44:42] <jthornton> no, I missed that. what's the volume of your water table?
[07:45:12] <Loetmichel> kfoltman: i DO engreaving bits sometimes
[07:45:26] <jthornton> will the plastic barrels fit under your table laying down?
[07:45:50] <ssi> jthornton: 33.5gal by calculation
[07:45:54] <ssi> yea I'm pretty sure they well
[07:45:55] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=10097
[07:46:03] <kfoltman> Loetmichel: that's much simpler though? (of course, still far from simple)
[07:46:03] <ssi> I'll just make a little cradle to hold one
[07:46:06] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=10097
[07:46:26] <kfoltman> hartkeks?
[07:46:28] <kfoltman> hard cake?
[07:46:32] <Loetmichel> oh
[07:46:40] <Loetmichel> sorry, wrong löink
[07:46:51] <jthornton> the plastic barrels might be the easy plum if they have two bungs, use the bottom bung for fill and drain of the liquid and the top bung for pressure/vent
[07:47:02] <ssi> yeah that's what I'm thinking
[07:47:14] <kfoltman> Loetmichel: you probably wouldn't grind that with diamond wheels ;)
[07:47:16] <ssi> one of them is a sealed lid, and one bung already has a ballcock in it
[07:47:20] <ssi> the other is a solid bung
[07:47:26] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=8961
[07:47:31] <Loetmichel> oh, i do
[07:48:16] <kfoltman> Loetmichel: those are just resharpened, or did you fabricate them?
[07:48:39] <Loetmichel> made out of old broken tc bit shafts
[07:48:43] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=8958
[07:49:15] <kfoltman> could be nice for PCB milling
[07:49:54] <kfoltman> so, you took a broken bit, ground off the leftovers, and ground the engraver bit off the remaining part of the shaft?
[07:50:07] <Loetmichel> yes
[07:50:10] <Loetmichel> https://www.youtube.com/watch?v=4iaFb6WInuw
[07:50:26] <Loetmichel> its easy if you know how
[07:51:12] <Loetmichel> ... took me about 20 to get it right the first time, though
[07:51:30] <Loetmichel> :-)
[07:51:40] <kfoltman> 20 tries?
[07:51:44] <Loetmichel> yes
[07:51:52] <kfoltman> what's the blue liquid?
[07:52:03] <Loetmichel> but i am in no short supply of broken sahfts
[07:52:08] <Loetmichel> windex
[07:52:39] <Loetmichel> just for cooling
[07:53:04] <Loetmichel> gets a little hot at the fingers
[07:53:59] <kfoltman> hmm, can you CNC *that*? :D
[07:55:37] <kfoltman> would probably need too many axes
[07:56:38] <Loetmichel> not sat all
[07:56:57] <Loetmichel> needs a rotational axis for the bit
[07:57:13] <Loetmichel> and maybe a means of tilting this axis
[07:57:16] <Loetmichel> done for
[07:57:59] <Loetmichel> so a 5 axxis or 4 axis with manual tilt will do
[07:59:10] <Loetmichel> it also works for cylindrical cuttes: http://www.cyrom.org/palbum/main.php?g2_itemId=12967
[07:59:14] <Loetmichel> cutters
[08:00:39] <Loetmichel> ... if you have a steady hand ;-)
[08:00:49] <kfoltman> cylindrical cutters?
[08:06:26] <kfoltman> carbide inserts?
[08:09:58] <ssi> holy crap I'm sore :/
[08:10:10] <Jymmmm> ssi: TMI
[08:10:17] <Loetmichel> kfolterman: "one flute"
[08:10:48] <Loetmichel> look at the pic
[08:11:07] <Loetmichel> it works like a 2mm 2 flute, just wit one cutting edge
[08:11:27] <Loetmichel> great for plastics and wood
[08:11:42] <Loetmichel> not so good for hard steel and aluminium, though
[08:12:56] <Loetmichel> needs a steady hand to do it without a grinding jig, .
[08:13:16] <Loetmichel> ans a few tries to get it right
[08:13:35] <Loetmichel> but as i said: i am in no short supply of broken carbide bits ;-)
[08:20:47] <ssi> Jymmmm: you know you love it
[08:21:02] <Jymmmm> ssi: Love to hate.
[08:21:48] <Jymmmm> JT-Shop: jthornton awake?
[08:22:03] <ssi> I went whitewater kayaking yesterday and my shoulders are angry
[08:22:34] <Jymmmm> ssi: You are suppose to be IN the kayak, not under it =)
[08:23:34] <jthornton> since 5 am
[08:23:41] <ssi> actually managed to stay in most of the day
[08:23:47] <Jymmmm> jthornton: PM
[08:24:16] <ssi> despite being in the absolute wrong boat
[09:17:49] <IchGuckLive> ssi: online ?
[09:23:17] <IchGuckLive> hi tronwizard
[09:25:54] <IchGuckLive> changing nick will effect all chanels inside server !
[09:26:43] <tronwizard> hello
[09:27:07] <IchGuckLive> @ all today the HeekscncCadCam is published to run on 14.10
[09:27:21] <IchGuckLive> Hi tronwizard
[09:27:56] <IchGuckLive> where are you located in our World imin germany
[09:29:14] <tronwizard> eastern PA. US
[09:29:36] <IchGuckLive> nice place to live
[09:29:46] <IchGuckLive> so do you already have a cnc
[09:29:58] <tronwizard> not yet, trying to scratch build
[09:30:27] <IchGuckLive> so what type do you going to build Plasma mill Lathe
[09:30:42] <tronwizard> lathe first
[09:30:43] <IchGuckLive> or even a robot
[09:30:50] <IchGuckLive> ok
[09:31:05] <tronwizard> then mill
[09:31:07] <IchGuckLive> lathe is best to retrofit a already good one for good results
[09:31:30] <ssi> ya I'm here
[09:31:45] <IchGuckLive> ssi: did ypou got the sheetcam post to work
[09:31:51] <IchGuckLive> like you liked it to be
[09:34:20] <IchGuckLive> tronwizard: i think Jt is right at your hometownes corner you shoudt connect in here some later this wek when all the folks of your nearby region are online
[09:34:37] <tronwizard> will do
[09:35:11] <IchGuckLive> tronwizard: what is the goal to meet with the lathe making parts for ?
[09:35:39] <tronwizard> just general purpose, probably robotics
[09:35:45] <IchGuckLive> that desides the way the mashine shoudt look like or getting build
[09:35:52] <ssi> IchGuckLive: more or less, yes
[09:36:05] <IchGuckLive> ssi: its allways thart way
[09:36:13] <SpeedEvil> https://www.youtube.com/watch?v=ZNHVeCUQxeY - just a general purpose lathe
[09:36:13] <IchGuckLive> more or less
[09:36:32] <ssi> it's pretty hacky
[09:36:41] <IchGuckLive> agree
[09:36:41] <ssi> basically the post is now incapable of making a Z negative move
[09:36:49] <ssi> only the touchoff and THC can do that
[09:37:13] <IchGuckLive> sheetcam plasma will never make a Z-
[09:37:18] <IchGuckLive> so dont worry
[09:38:18] <IchGuckLive> ssi i did a spring load on the torch that acts as a fail movement of the thc
[09:38:35] <IchGuckLive> as your THC can move the mashine down till break
[09:38:50] <IchGuckLive> its a 3mm way to zero
[09:39:17] <IchGuckLive> so if it goes down on workheight in action it will be stopt
[09:39:28] <IchGuckLive> all the mashine goes E-stop
[09:40:04] <IchGuckLive> therfor i used the M160 M161 with usercomment COMP settings
[09:40:25] <IchGuckLive> the plasma Your hypertherm got also M66 M67 access to the axis
[09:40:34] <IchGuckLive> via 5i24
[09:40:36] <IchGuckLive> 25
[09:41:06] <ssi> I use M66 for arc transfer
[09:41:09] <IchGuckLive> so all the sheetcam G4 are now Taken off by M66
[09:41:13] <ssi> I don't know what M160/161 is
[09:41:26] <ssi> it'd be userdef I gues
[09:41:40] <IchGuckLive> for me its sets THCUD-enabled
[09:42:23] <IchGuckLive> True and Fase
[09:42:27] <IchGuckLive> False
[09:42:44] <IchGuckLive> so the THC is not working bevor M5
[09:42:58] <ssi> oh I see
[09:43:06] <IchGuckLive> and is on only after retched Zworkflow
[09:43:38] <IchGuckLive> Zworkflow can only be retched if the torch has firered after pircing
[09:44:10] <IchGuckLive> so workflow here
[09:44:23] <IchGuckLive> Move to new Start point Z safe Height
[09:44:36] <IchGuckLive> wait if plasma is ready to fire
[09:44:45] <IchGuckLive> go to pirce height
[09:44:51] <IchGuckLive> M3
[09:44:58] <IchGuckLive> wait if arc is ok
[09:45:07] <IchGuckLive> go to workpice height
[09:45:19] <IchGuckLive> enable THC
[09:45:28] <IchGuckLive> move path
[09:45:33] <IchGuckLive> disable THC
[09:45:38] <IchGuckLive> M5
[09:45:44] <IchGuckLive> Safe Height
[09:46:05] <IchGuckLive> new staert point
[09:46:34] <IchGuckLive> this works on hypertherm the full workday with near no ED
[09:46:57] <IchGuckLive> it takes 2min to load and unload the sheeds
[09:47:17] <ssi> "wait if plasma is ready to fire" what does this consist of
[09:48:01] <IchGuckLive> your plasma has a blow out time that triggers a relay and that can be used to see if it ready to take the next shot
[09:48:22] <IchGuckLive> The air afterflow at Arc Stops
[09:49:01] <IchGuckLive> lets say you make a 1inch Sqare array
[09:49:16] <IchGuckLive> 10x10 so 100 cuts
[09:49:54] <IchGuckLive> your hypertherm will not cut them all as it takes time from stop to next start and your plasma may be quicker then that
[09:50:01] <IchGuckLive> so m3 does not firer
[09:55:00] <IchGuckLive> ok im off till 7pm berlin time see you later
[09:56:28] <ssi> I don't think my machine has an output for that
[09:57:03] <ssi> also I wonder if I should be pausing at the end of cuts before rapiding to the next pierce for afterflow...
[09:57:14] <ssi> would certainly add a lot of time to cuts with lots of pierces
[10:15:44] <kfoltman> Loetmichel: my most recent broken endmill was due to over-optimistic rapid in Z axis
[10:16:35] <kfoltman> no matter how high the Z axis seems to be, G91 G00 Z-60 is never a good idea
[10:17:52] <ssi> it's good to know where your safe heigh is :)
[11:11:07] <JT-Shop> my 1250 has a cool down after each cut about 5 seconds with air on
[11:11:44] <JT-Shop> ssi, you been following the conversation on the devel mailing list on the thcud component?
[11:17:02] <XXCoder> wow.
[11:17:12] <XXCoder> some people is retard on selling cars
[11:17:31] <XXCoder> 1986 car, needs parts to be complete, $2500
[11:17:42] <XXCoder> yeah and fairies might fly out of my ass
[11:18:32] <XXCoder> and wtf with night picture ones? must have really bad damage
[11:30:40] <Loetmichel> XXCoder: so? nobody presses you to buy them
[11:49:26] <Loetmichel> kfoltman: i have about 2kg of broken 1/8" tc bit shafts here ;-)
[11:49:38] <Loetmichel> ... and that is from about 4 years of milling.
[11:50:01] <Loetmichel> more than eough stuff to grind engraving bits/special mill bits ;-)
[11:52:02] <XXCoder> Loetmichel: yeah but still lols around
[11:54:15] <XXCoder> lol know guy just out large number in, but this is funny https://seattle.craigslist.org/sno/cto/4540960923.html
[11:55:06] <XXCoder> cheap at below 4 million bucks https://seattle.craigslist.org/see/ctd/4511904296.html
[11:55:43] <XXCoder> below 40 million I mean lol
[11:55:49] <XXCoder> https://seattle.craigslist.org/see/cto/4514979661.html might be better deal :P
[12:13:58] <IchGuckLive> hi all B)
[12:14:39] <XXCoder> hey supercncman
[12:14:58] <IchGuckLive> O.O
[12:15:06] <IchGuckLive> not me to many crashes
[12:16:06] <IchGuckLive> ssi: ?
[12:16:30] <XXCoder> lol
[12:16:53] <IchGuckLive> i like to do the drawinds and all the fun stuff
[12:17:11] <kfoltman> drawind is a drawing done by the wind? (-:
[12:17:26] <IchGuckLive> XXCoder: the mashining is not my thing only the things till press Rubn
[12:18:06] <IchGuckLive> kfoltman: http://www.youtube.com/watch?v=6NTa4EIMXAY There you go
[12:18:11] <IchGuckLive> German
[12:18:38] <IchGuckLive> windy constructions with gimp
[12:18:43] <IchGuckLive> and openclipart
[12:21:51] <XXCoder> still waiting for more parts bahh
[12:22:04] <XXCoder> shipping from chinese is so slow
[12:22:28] <kfoltman> XXCoder: what parts are you waiting for?
[12:22:34] <IchGuckLive> you got plenty of time till x-mas
[12:22:35] <XXCoder> coupler, motor mount
[12:22:57] <XXCoder> also ordered dial indictor and better digital caplier
[12:24:39] <SpeedEvil> http://www.banggood.com/LM16UU-16mm-Linear-Motion-Ball-Bearing-Carbon-Steel-Linear-Bushing-p-931396.html
[12:24:45] <SpeedEvil> what can possibly go wrong?
[12:24:46] <IchGuckLive> oh you getting professionell
[12:25:00] <XXCoder> 2 bucks lol
[12:25:51] <XXCoder> interesting https://scontent-b-sea.xx.fbcdn.net/hphotos-xpf1/t1.0-9/1468696_663396193730088_4009966441536232679_n.jpg
[12:25:59] <IchGuckLive> SpeedEvil: i use the LM20UU
[12:26:56] <kfoltman> SpeedEvil: I use the open bearing blocks for supported rails instead
[12:27:02] <kfoltman> the LM seem too hard to mount
[12:27:22] <kfoltman> like, what the hell am I suppose to do with those round things?
[12:27:27] <SpeedEvil> I'd wondered about that - using floating supports
[12:27:38] <IchGuckLive> they got a sceaw for tighten up
[12:28:05] <kfoltman> SpeedEvil: floating supports?
[12:28:31] <kfoltman> SpeedEvil: http://www.cnc4you.co.uk/index.php?route=product/product&product_id=411 that's the stuff I'm using
[12:28:47] <kfoltman> except mine are bought in China and pretty rough
[12:29:27] <SpeedEvil> kfoltman: Take a horizontal lever with a magnet on the right bottom side, a piviot in the middle and a stop on the top left.
[12:29:40] <SpeedEvil> the carridge can bang it out of the way
[12:31:02] <IchGuckLive> the 2m foam cutters got them inside
[12:31:04] <kfoltman> SpeedEvil: derp?
[12:31:18] <SpeedEvil> kfoltman: ?
[12:31:22] <SpeedEvil> y
[12:31:24] <kfoltman> SpeedEvil: I don't know half of the words :)
[12:32:05] <SpeedEvil> kfoltman: Ok, my spelling may be dodgy
[12:32:16] <kfoltman> SpeedEvil: no, I mean the mechanical terms
[12:32:18] <IchGuckLive> with the LmUU you only need a good straightr drill press to get realy good CHEEP moving CNC
[12:32:29] <SpeedEvil> kfoltman: they're not very mechanical.
[12:32:44] <IchGuckLive> ok on a 2inch hole you realy need a good drill press
[12:33:05] <XXCoder> heh was thinking about dimensions. wonder what 4d cnc would be like
[12:33:22] <kfoltman> IchGuckLive: you mean, simply making a hole with a drill press in a block of steel/aluminium and mount to that?
[12:33:30] <kfoltman> + drill and tap some mounting holes
[12:33:30] <XXCoder> it would be able to make holes in middle of solid material for one
[12:34:09] <kfoltman> few drill presses can handle diameters >16mm
[12:34:13] <IchGuckLive> i did drill all 4 pices in one shot so the holes are even in all 4 pices 2side and 2 running
[12:34:30] <SpeedEvil> https://en.wikipedia.org/wiki/Photodisintegration is an underused process in machining
[12:34:44] <kfoltman> and even LM12UU's outer diameter seems to be more than that
[12:34:55] <SpeedEvil> kfoltman: spade bit

[12:35:12] <kfoltman> SpeedEvil: that's for wood, isn't it?
[12:35:13] * SpeedEvil should stop trolling.
[12:35:22] <SpeedEvil> kfoltman: yes - I have used it for aluminium.
[12:35:34] <XXCoder> interesting machine
[12:35:37] <kfoltman> SpeedEvil: 2 bits per hole? might get expensive ;)
[12:35:41] <SpeedEvil> But the quality of hole is not really acceptable for anything
[12:35:58] <SpeedEvil> kfoltman: It's not actually bad - with a nice sharp bit and coolant
[12:36:07] <SpeedEvil> and the right predrilled hole.
[12:36:19] <kfoltman> I guess you could step-drill it or something
[12:36:32] <SpeedEvil> But it's more desperation than anything else that leads one to that
[12:36:49] <IchGuckLive> it is drilled as 12mm hole 25mmhole 30mm hole 35mm 38mm and then reamer 40H7
[12:36:50] <kfoltman> or evacuate the estate for 2 months and pocket-mill it ;)
[12:36:58] <IchGuckLive> in one position
[12:37:15] <IchGuckLive> it works fine
[12:37:23] * kfoltman never used reamers
[12:37:55] <IchGuckLive> http://www.youtube.com/watch?v=wT_ndXDZ0DU
[12:38:05] <IchGuckLive> casel in one shot
[12:38:07] <kfoltman> what's the advantage over the normal twist drill? accuracy/finish?
[12:38:21] <kfoltman> IchGuckLive: castle ;)
[12:39:14] <IchGuckLive> this is the part that started the hole CNC boom here and around it is placed on top of the shop in mainstreet
[12:39:32] <IchGuckLive> stone coted
[12:41:14] <kfoltman> can this kind of hot wire machine cut harder plastics?
[12:41:36] <IchGuckLive> only EPS
[12:41:49] <kfoltman> EPS? e... polystyrene?
[12:41:52] <IchGuckLive> WDV1000 will brek the wire
[12:43:18] <XXCoder> I bet that wire cnc can make round stuff
[12:43:26] <XXCoder> just rotate while cutting I think
[12:43:51] <kfoltman> XXCoder: duh, that's what 5 axis drive is for
[12:44:52] <IchGuckLive> XXCoder: http://ww3.cad.de/foren/ubb/uploads/Magic33_de/saule_a_k.jpg ;-)
[12:45:02] <IchGuckLive> its fun to see the cnc shape it
[12:45:07] <XXCoder> nice!
[12:45:13] <IchGuckLive> only 5 cuts
[12:45:46] <IchGuckLive> the problem is to get the sand stick at that shape
[12:46:24] <kfoltman> meh, myself I have no use for foam materials, but for artists it has great potential
[12:46:38] <XXCoder> isnt foam also can be used for pour mold?
[12:46:55] <IchGuckLive> XXCoder: and then you can do masterpices like that http://ww3.cad.de/foren/ubb/Forum12/HTML/022092.shtml
[12:47:50] <IchGuckLive> XXCoder: you got Alu800 for that the mold is suposed to stand 5000pice
[12:48:26] <IchGuckLive> THE masteroice is cuted on that mashine as the castel is
[12:49:27] <IchGuckLive> its one block at 25Euros and sold at 350Euros
[12:49:40] <IchGuckLive> 2,5Hr work
[12:49:48] <XXCoder> interesting
[12:49:52] <XXCoder> well gonna go later
[12:52:59] <SpeedEvil> http://www.mauve.plus.com/Chinese-Lantern.jpg - sort-of-related
[12:53:11] <IchGuckLive> since economic issues here in Europ as Houses gone be packed it is nice to shape parts for better house styling
[12:53:52] <SpeedEvil> The bottom third was cast in a polystyrene mould made from a 60cm or so cube, hot-wire cut, and then reassembled into the appropriate shape and concrete filled
[12:54:05] <IchGuckLive> By the Way the new Heeks packet is upgreated today to meet the 14.10 install
[12:55:08] <IchGuckLive> SpeedEvil: yeah concreed molds is the moneymaker here 2
[12:55:25] <SpeedEvil> DIY - it's in my garden
[12:55:53] <IchGuckLive> use a robot to get a good big shape
[12:56:21] <IchGuckLive> i wil shure iss that system as i stad out this year from job
[13:00:32] <IchGuckLive> HERE is a good html for robot to G-code joint detaction
[13:01:29] <IchGuckLive> Einar1: hi
[13:01:53] <IchGuckLive> yesterday i final throwed all my Servo stuff in the garbage
[13:02:01] <SpeedEvil> ebay!
[13:02:09] <SpeedEvil> It's like garbage, but better!
[13:02:54] <IchGuckLive> as i dident get any single full turn out of the servo in nearly 2years and maybe 200 and more houres of work on it i spend neat 2000Euros on it and had nothing to show
[13:06:16] <IchGuckLive> ok im off BYE till tomorrow ;-)
[13:07:55] <archivist> tut tut
[13:19:38] <kfoltman> SpeedEvil: heh
[13:19:47] <kfoltman> SpeedEvil: "it's like garbage, but better and not free"
[13:19:59] <SpeedEvil> better if you've got stuff to sell
[13:20:19] <kfoltman> ah, yes, I skipped what IchGuckLive said about his servos
[13:20:37] <kfoltman> I should put some of my blue servos in the bin ;)
[13:23:45] <kfoltman> anyone ever used L293E for anything?
[13:23:55] <jdh> lots of people have.
[13:40:59] <ssi> jthornton: yea I saw the stuff on the list
[14:03:01] * JT-Shop thinks he farted around with sheetcam and wiped out the latest tools and lost the kerf width info
[14:03:24] <Jymmm> sheetcam = windows?
[14:04:31] <ssi> JT-Shop: onoes
[14:10:24] <Jymmm> ANALOG RULES!!! http://www.iflscience.com/plants-and-animals/what-do-tree-rings-sound-when-played-record
[14:11:56] * JT-Shop looks for some scrap 16ga to get some data from for the FC nozzle
[14:12:20] <JT-Shop> and I'm out of data bandwidth
[14:12:42] <Jymmm> JT-Shop: you have cell coverage there?
[14:12:59] <LeelooMinai> Jymmm: I am pretty sure that was done using digital:)
[14:13:18] <Jymmm> LeelooMinai: Bite me, it was analog damnit! lol
[14:13:33] <JT-Shop> yea, but only have 1GB of data shared on two phones
[14:14:24] <Jymmm> ah
[14:18:54] <Jymmm> I need to center in x and y axis 1.5" discs that have a slop tolerance. I know I can use a V slot in a fixture for at least one axis, but not the other. concentric stepped rings was suggested, but...
[14:19:21] <ssi> not stepped, tapered :P
[14:19:57] <Jymmm> the max fixture height is 1/8". I did find Thales' Theorem, and I'm wondering if somehow it could be applied to gets these discs "dead center" ?
[14:20:23] <Jymmm> I also need to flip the fixture over
[14:20:36] <Jymmm> with it's content still in place.
[14:21:12] <Jymmm> http://www.mathopenref.com/thalestheorem.html
[14:24:12] <Jymmm> Easier example: http://handmademusicclubhouse.com/forum/topics/how-to-find-the-center-of-a
[14:26:07] <Jymmm> I know there has to be a simple approach to this =)
[14:27:24] <Jymmm> ssi: yes yes, tampered, stepped, concentric, stacked, fluffed, folded, whatever =)
[14:27:47] <ssi> stepped implies that it'll fit a discrete set of different diameters very closely
[14:27:58] <ssi> tapered implies it'll fit any diameter within a min and max range
[14:28:02] <ssi> there's QUITE a big difference
[14:29:13] <Jymmm> ssi: If I used tampered, then the surface may not be level. stepped, it would be.
[14:29:18] * JT-Shop finds a kerf chart in the torch manual
[14:29:36] <Jymmm> tapered*
[14:29:47] <ssi> if you use a pair of outer tapered plates that make a V and inverted V, they will always be level and concentric
[14:30:43] <Jymmm> ssi: but not centered =)
[14:30:51] <ssi> concentric implies centered
[14:31:14] <Jymmm> ssi: Then I don't follow your descrition.
[14:31:14] <ssi> words, man. they mean things.
[14:31:27] <ssi> if you have a snow cone cup
[14:31:31] <Jymmm> ssi: Bah, words get in the way. pics man, pics!
[14:31:32] <ssi> and you put a golf ball in it
[14:31:34] <ssi> it'll be centered
[14:31:39] <ssi> if you put a tennis ball in it, it'll be centered
[14:31:40] <Jymmm> ok
[14:31:59] <ssi> if you put a quarter in it, it'll be centered, and also likely level
[14:32:02] <Jymmm> ssi: these are not balls, they are discs, like a silver dollar
[14:32:08] <Jymmm> poker chip
[14:32:11] <ssi> yes I know
[14:32:38] <ssi> the only problem with this scheme is the fact that the surface of each chip will be at a different height depending on the diameter
[14:33:29] <Jymmm> ignoring that for a moment... I understand the V-groove, but only in the X axis, what about Y ?
[14:33:45] <ssi> snow cone cup
[14:33:52] <ssi> it's a V groove in the Z direction
[14:33:56] <ssi> it'll center in X and Y
[14:33:58] <Jymmm> 1/8" tall snow cone?
[14:34:02] <ssi> sure
[14:34:10] <ssi> or at least a slice of one
[14:34:15] <Jymmm> the chip will tilt
[14:34:19] <Jymmm> \
[14:34:25] <Jymmm> instead of --
[14:34:31] <ssi> where the diameter of the hole at the bottom of the plate is slightly smaller than the smallest chip, and the diameter at the top is slightly larger than the largest chip
[14:34:53] <Jymmm> \ /
[14:35:11] <Jymmm> or < >
[14:35:17] <jdh> sort and/or cull the chips
[14:35:23] <ssi> each plate is \ /, together they make < >
[14:35:30] <Jymmm> But that is only a single axis, what about the other?
[14:35:38] <ssi> sigh
[14:35:38] <ssi> never mind
[14:38:02] <Jymmm> ssi: are you talking sandwichin two plates together?
[14:38:34] <Jymmm> Top / \
[14:38:41] <Jymmm> Bot \ /
[14:38:49] <Jymmm> and the chip in between?
[14:38:51] <ssi> yen
[14:38:54] <ssi> yes
[14:39:04] <Jymmm> ssi: How do you fasten them together?
[14:39:16] <ssi> I dunno, scotch tape
[14:39:19] <ssi> figure it out
[14:39:37] <ssi> and here I prepared a series of pictures to try to beat it into you
[14:39:47] <Jymmm> scotch tape will tdo the edges, and thw chips in the middle of the fixture will slap around.
[14:40:34] <Jymmm> the compression of the tw plaes is what keeps the discs centered. it has to be consistant across all the 25 holes
[14:40:40] <Jymmm> two*
[14:40:50] <ssi> https://pbs.twimg.com/media/BrUhocjIcAESlCx.jpg
[14:40:55] <ssi> https://pbs.twimg.com/media/BrUhrI3IEAIxXjV.jpg
[14:40:59] <ssi> https://pbs.twimg.com/media/BrUhvz1IYAAa0ye.jpg
[14:41:01] <ssi> all centered
[14:41:03] <ssi> all level
[14:41:14] <Jymmm> If I can't "fasten" them evenly across the whole surface, then some will be loose
[14:41:42] <Jymmm> Yes, this pics are your "snow cone" example. I get that.
[14:41:48] <Jymmm> those*
[14:41:51] <ssi> yeah now you get it
[14:42:00] <ssi> somewhere around the time I was trying to upload all those it finally dawned on you :P
[14:42:07] <ssi> I wasn't about to let it go to waste
[14:42:16] <jdh> could you show me again, but this time in red?
[14:42:24] <jdh> and make them perpendicular?
[14:42:32] <Jymmm> But the compression acros the whole sirface has to have even tension between top/bottom
[14:42:33] <ssi> sorry the only colors I have right now are gold and silver
[14:42:44] <ssi> use little spring fingers on the top of the plate instead of a top plate
[14:42:50] <ssi> that just holds the edges down on four points
[14:43:01] <ssi> or a big belleville washer
[14:43:02] <ssi> something
[14:43:06] <ssi> I dunno, use your massive brain
[14:43:17] <jdh> undocumented immigrants
[14:45:43] <Jymmm> ssi: Again, 1/8" height, and top/bottom (flipped) heights have to be even.
[14:45:56] <ssi> yes I understand all this
[14:46:18] <ssi> at the end of the day you're going to have to sort and batch the chips
[14:46:21] <ssi> make a sorting plate to do that
[14:46:47] <ssi> if you use this method and batch the chips, you can use the same fixture for all of them, and heights will be consistent
[14:47:45] <Jymmm> I am not going to "sort" 1000 chips
[14:47:50] <ssi> ok
[14:48:28] <Jymmm> (I eventually want to automate the process, but need a fixture til then)
[14:49:54] <Jymmm> And I do understand your idea, but if I get an oversied chip, it's gonna snap when fastened down, or "bow" the plates.
[14:50:23] <Jymmm> if there are undersized chip near it, they will slop around.
[14:50:26] <ssi> maybe you should just let another contractor do this job :P
[14:50:55] <Jymmm> ssi: But you are not acknowledging what *I* am saying.
[14:51:07] <Jymmm> ssi: Maybe you don't "get it"
[14:51:16] <ssi> ok, I don't get it
[14:51:31] <archivist> he understands your confusion
[14:51:32] <Jymmm> ssi: And you don't have to be a smartass about it either.
[14:51:37] <ssi> I'm not being a smartass
[14:51:40] <ssi> I'm being realistic
[14:51:55] <ssi> I think if you did what I'm suggesting and did some presorting, you'd have some success
[14:52:06] <ssi> but if presorting is out of the question, then by all means come up with a better way to do it
[14:52:16] <ssi> but personally I'm not smart enough to come up with a foolproof solution without sorting
[14:52:21] <ssi> so, sorry for that
[14:52:47] <archivist> add springs per unit
[14:53:21] <ssi> three or four spring fingers should hold it level and centered in a tapered hole
[14:53:35] <ssi> if the chips in one batch are all roughly the same diameter, they should all have the same height
[14:53:41] <Jymmm> ssi: It has nothing to do with that, it's just that approach isn't preacticla for this application.
[14:53:52] <Jymmm> ssi: till you flip the fixture over.
[14:53:58] <ssi> it'll work upside down too
[14:54:10] <ssi> just need to have spacers to hold the plate off the spring fingers
[14:54:30] <Jymmm> which would change the surface height
[14:54:41] <ssi> sure, but it'll be consistent for the batch
[14:54:51] <ssi> perhaps I don't understand the limitations of your machine
[14:55:01] <ssi> is there one and only one Z height you can focus on?
[14:55:09] <Jymmm> laser focus == consistant height, both sides
[14:55:32] <ssi> so how do you engrave a 1/8" piece and then later a 3/16" piece?
[14:55:37] <Jymmm> yes, a single height for all 100
[14:55:39] <ssi> do you have to shim everything up to that magic height?
[14:57:11] <Jymmm> I have a tolerance across the entire table I have to work within
[14:57:20] <ssi> you're not answering the question
[14:57:33] <ssi> I understand that for one operation, you have to run one focal height
[14:57:43] <ssi> what I'm asking is, for a second operation, can you not run a different height?
[14:58:01] <Jymmm> on the same batch or different job?
[14:58:16] <ssi> same batch, second operation
[14:58:23] <ssi> for all practical purposes, it could be a different job
[14:58:23] <Jymmm> yes
[14:58:46] <XXCoder> heys
[14:58:47] <Jymmm> well different job, differen heights
[14:58:53] <XXCoder> ssi any luck with selling?
[14:59:00] <ssi> XXCoder: nah, haven't really been trying
[14:59:05] <XXCoder> lolmok
[15:07:03] <JT-Shop> ssi, just cutting some really bent crap 16ga and the thc comp is not following as well as I thought it did on the way back down from a hump
[15:07:28] <ssi> JT-Shop: I dont' have a good picture of how well mine is following
[15:07:49] <ssi> I know it's moving, but I'm using that needle gauge you had in your vcp and it bounces all over the place
[15:11:36] <JT-Shop> the volts
[15:11:46] <ssi> yes
[15:12:18] <JT-Shop> I was just watching the top of the torch and could see it jump at one point and on the downhill run the kerf got wider and it didn't seem to go down as much
[15:12:25] <ssi> ahh
[15:12:37] <JT-Shop> glad I'm cutting scrap
[15:12:58] <ssi> I wonder why it's not following
[15:13:03] <ssi> the jump sounds odd
[15:14:23] <jthornton> there was a small kink in the material
[15:17:15] <XXCoder> lol https://www.youtube.com/watch?feature=player_embedded&v=o_XaJdDqQA0
[15:17:30] <XXCoder> dont do that with your router computer. it might take your router with it too ;)
[15:19:52] <zee-Lathe> bah
[15:20:09] <zee-Lathe> anyone have a screnshot of what spindle a and spindle index should look like in hal scope
[15:20:31] <ssi> index really can be anywhere
[15:20:38] <ssi> a and b need to be 90 degrees out of phase from each other
[15:20:42] <zee-Lathe> i dont have b
[15:20:46] <zee-Lathe> only index and a
[15:21:16] <zee-Lathe> lemme take a screenshot
[15:32:58] <zee-Lathe> laggg
[15:33:17] <XXCoder1> yeah
[15:36:23] <zee-Lathe> http://i.imgur.com/1UQvGLN.png
[15:36:27] <zee-Lathe> does that look normal?
[15:36:45] <zee-Lathe> or should i invert the spindle-index signal?
[15:42:13] <JT-Shop> to test your index signal http://www.gnipsel.com/linuxcnc/tuning/encoder.html
[15:57:56] <XXCoder> https://imgur.com/a/NGbmh
[15:57:58] <XXCoder> not bad!
[16:05:40] <archivist> erm /me may have spotted a flaw
[16:06:37] <XXCoder> what flw?
[16:07:32] <archivist> couplers, is the stepper the bearing for the drive screw
[16:09:28] <XXCoder> hmm
[16:09:31] <XXCoder> yeah
[16:10:47] <archivist> you have three bearings in a rigid line, so the coupler/screw has to flex
[16:11:16] <zeeshan|2> thanks JT-Shop i will try that out
[16:11:31] <archivist> expect couplers to come loose at some stage
[16:13:06] <zeeshan|2> spindle-speed-in is in RPS
[16:13:12] <zeeshan|2> but it fluctuates a lot
[16:13:14] <zeeshan|2> is that normal?
[16:13:17] <zeeshan|2> especially at high rpm
[16:13:25] <zeeshan|2> (fluctuates in hal monitor)
[16:14:13] <archivist> you can to teh maffs to convert to rpm and also pass the signal through a low pass filter
[16:14:23] <zeeshan|2> huh
[16:14:27] <zeeshan|2> :)
[16:16:21] <XXCoder> https://www.youtube.com/watch?feature=player_embedded&v=UxXSHDdlh_E lol

[16:18:36] <XXCoder> captoned too. bonus!
[16:22:35] <XXCoder> lol nice
[16:28:16] <zee-Lathe> JT-Shop, i tried your guide
[16:28:30] <zee-Lathe> it stays false?
[16:28:58] <XXCoder> brb updating irc client
[16:36:28] <zee-Lathe> parport.0.pin-10-in and encoder.0.phase-Z both go "FALSE" when the encoder is on the empty spot on the encoder disc
[16:38:47] <XXCoder> I hate how updates kill gtk+ theme
[16:38:54] <XXCoder> I had to restore it each time
[16:43:01] <zee-Lathe> update spindle-index,encoder.0.phase-Z is TRUE when the encoder plate slot for index is lined up with the encoder
[16:43:13] <zee-Lathe> but spindle-index-enable remains false

[16:59:22] <SpeedEvil> (not really)
[16:59:43] <XXCoder> easy
[16:59:52] <XXCoder> first, own a country.. a first world one.
[17:00:38] <XXCoder> second step is easier. "Make me this!"
[17:01:31] <SpeedEvil> Actually - $600K isn't that much
[17:01:40] <SpeedEvil> in context.
[17:01:52] <SpeedEvil> Compared to the cost of say a similarly specced spacesuit
[17:01:53] <XXCoder> guess so. I'd rather buy house and car though
[17:02:16] <SpeedEvil> Pizza and poop hatch - and why'd you need a house?
[17:05:41] <zee-Lathe> man what is going on here!!
[17:05:42] <zee-Lathe> grr
[17:05:49] <zee-Lathe> encoder position is outputting right
[17:11:07] <jfigie> I would like to make a exosuit to help me lift heavy objects
[17:14:33] <jfigie> I need it to lift my vise on and off my machine. I can do it now but what about when I am 70?

[17:17:16] <jfigie> neodymium magnets?
[17:17:25] <XXCoder> room crane
[17:18:23] <jfigie> that sounds too practical :)
[17:18:36] <XXCoder> powered by fusion
[17:19:10] <jfigie> fusion from metal chips as fuel
[17:19:35] <XXCoder> fusion loses energy in materials at iron and heavier atoms
[17:19:43] <XXCoder> fission is better
[17:20:01] <XXCoder> in fact, iron is base, you cant gain energy by fusion or fission with it
[17:28:05] <XXCoder> also: stars died so we can exist.
[17:28:09] <XXCoder> think of them please!
[17:28:10] <XXCoder> ;)
[17:30:02] <jdh> I didn't ask them to die for me.
[17:30:13] <jdh> a little presumptuous, don't you think?
[17:30:16] <XXCoder> lol
[17:32:45] <XXCoder> seriouslu though if not for stars and fusion we wouldnt be around
[17:45:12] <Jymmm> XXCoder: s/stars and fusion/porn/
[17:45:27] <XXCoder> lol
[17:45:47] <Jymmm> XXCoder: that soldering is on sale for $16 this week
[17:45:55] <Jymmm> FYI
[17:46:14] <XXCoder> yeah cant buy it for now, my car now dumps water pretty quick.
[17:46:27] <XXCoder> I fixed one hose. well "fixed" but its still leaking somewhere else
[17:46:30] <Jymmm> ouch, sorry to hear that.
[17:46:58] <Jymmm> is it a hose or radiator/pump?
[17:47:02] <XXCoder> didnt expect it, it have had p1744 error for ford contour thats "code of death"
[17:47:03] <Jymmm> or sensor
[17:47:17] <XXCoder> jose was part of it, something else elsewhere
[17:47:43] <Jymmm> Code P1744:
[17:47:43] <Jymmm> Torque Converter Clutch System Stuck In Off Position
[17:47:54] <XXCoder> yep
[17:48:02] <XXCoder> it breaks tranmission evenually
[17:48:06] <Jymmm> ah
[17:48:19] <Jymmm> I can help you find the leak if you want
[17:48:24] <Jymmm> it's easy
[17:48:51] <XXCoder> use glow in dark fluid? ;)
[17:48:57] <Jymmm> Nah
[17:49:52] <Jymmm> Get a Presetone Radiator flush kit and install it.
[17:50:08] <XXCoder> spend money? when it has code of death?
[17:50:39] <Jymmm> https://answers.yahoo.com/question/index?qid=1006042607609
[17:50:58] <Jymmm> Ok, then strip it and scrap it for $500.... PROFIT!
[17:51:51] <XXCoder> I poured antislip fluid in tranmission
[17:51:58] <XXCoder> it should be fine for a bit
[17:52:08] <Jymmm> but that's spending money =)
[17:52:21] <XXCoder> limited money
[17:52:22] <zee-Lathe> when i do setp lowpass.0.gain 0.01 and then net spindle-velocity => lowpass.0.in and then monitor lowpass.0.out
[17:52:34] <zee-Lathe> even though lowpass.0.in is registering 3.231
[17:52:37] <Jymmm> if could be a faulty wire/valve, ford harnesses are not always the best.
[17:52:46] <zee-Lathe> lowpass.0.out is 0. no matter what lowpass.0.in is.
[17:52:50] <zee-Lathe> any ideas? ;/
[17:52:54] <Jymmm> no money to test it either.
[17:54:08] <zee-Lathe> oh i needed to addf lowpass.0 servo-thread
[17:54:09] <zee-Lathe> to make it work
[17:56:26] <MrHindsight> does the stepgen for each axis still need a little extra % over the trajectory planner?
[17:56:34] <MrHindsight> or did that get fixed?
[17:57:13] <Jymmm> HAHA https://www.youtube.com/watch?v=sHzdsFiBbFc
[18:40:58] <CaptHindsight> http://www.automationtechnologiesinc.com/products-page/breakout-boards/kl-db25-breakout-board beware they used a common ground for each opto input but also tied a pullup resistor to 5V+ for you, so you're stuck with using 5V on your switches or having to use another buffer/relay etc to use 24V
[18:42:21] <CaptHindsight> great, 5V logic on your limit and home switches. No wonder people have so many problems setting up their machines
[18:44:11] <zeeshan|2> CaptHindsight:
[18:44:16] <zeeshan|2> whats wrong with 5v on limit switches?
[18:44:30] <humble_s1a_bass> 3.3 IS MUCH MORE COMMON
[18:44:45] <CaptHindsight> maybe nothing on a tiny toy machine, but not in an industrial environment
[18:44:57] <zeeshan|2> i agree
[18:45:01] <zeeshan|2> industrial is 24VDC standard
[18:45:15] <zeeshan|2> less chance of accidental noise trip
[18:45:45] <CaptHindsight> but this board doesn't tell you that they used pullups on the opto inputs
[18:46:19] <zeeshan|2> i think pullups are pretty standard
[18:46:30] <zeeshan|2> cause if they didnt have pullups, people would be burning their boards :p
[18:46:31] <CaptHindsight> what the F*** is the point of even using optos if the 5V and ground is common to both side of the optos?
[18:47:02] <zeeshan|2> haha
[18:47:05] <zeeshan|2> are you serious?
[18:47:18] <CaptHindsight> yes, it's moronic
[18:47:58] <zeeshan|2> okay lightning stopped
[18:48:03] <zeeshan|2> can finally test out threading
[18:48:48] <CaptHindsight> I can see having series resistors on the inputs to limit current through the diodes
[18:49:11] <zeeshan|2> usually they put 1k ohm resistors
[18:49:44] <CaptHindsight> but why the pull-ups?
[18:50:23] <zeeshan|2> im not an electronics expert, but from what ive expierenced, its to mainly limit current
[18:50:29] <zeeshan|2> and ensure the transitor switches correctly
[18:50:40] <CaptHindsight> thats what the series resistors are for
[18:52:09] <zeeshan|2> hey is there a way to test spindle and z axis motion?
[18:52:15] <zeeshan|2> say i manually rotate the spindle
[18:52:25] <zeeshan|2> is there a way to proportionally move the z
[18:58:31] <XXCoder> hey CaptHindsight
[19:00:00] <CaptHindsight> XXCoder: yes?
[19:00:06] <XXCoder> whats up man
[19:00:17] <CaptHindsight> just workin
[19:00:48] <XXCoder> nice :)
[19:00:59] <CaptHindsight> and checking out all the cheap breakout boards from China/ebay/Keiling etc etc
[19:01:09] <CaptHindsight> no to poor docs
[19:01:14] <CaptHindsight> wrong info
[19:01:20] <XXCoder> fun
[19:01:25] <CaptHindsight> a real mess for noobs
[19:02:03] <XXCoder> yeah thats why I wrnt for kit lol
[19:02:06] <CaptHindsight> I've been trying them since they come with a cable and board for practically the same price as the cable alone
[19:02:35] <CaptHindsight> I'll put it up on the wiki when I get a chance
[19:03:19] <CaptHindsight> http://www.automationtechnologiesinc.com/wp-content/plugins/download-monitor/download.php?id=240
[19:03:23] <XXCoder> that is poretty cheap
[19:03:32] <CaptHindsight> look at the info it comes with ^^^
[19:03:54] <CaptHindsight> with no explanation of the jumpers
[19:04:37] <XXCoder> text in all directions. nice lol
[19:04:43] <CaptHindsight> I think the grounds are tied no matter what jumper setting and the 5V can be isolated from one side of the optos to the other BUT....
[19:05:17] <CaptHindsight> the caps on the opto side are only rated for 16V, so only good for 12V logic max
[19:05:56] <CaptHindsight> so forget about 24V logic unless you want to add another layer or buffers/relays/level translators
[19:06:03] <CaptHindsight> or/of
[19:06:15] <XXCoder> making something out of "free" board and stuff?
[19:08:46] <CaptHindsight> no, just testing, I can't make anything with this junk, except junk :)
[19:09:08] <XXCoder> make gluegun machine
[19:09:13] <XXCoder> laser? lol
[19:10:34] <MrHindsight> it can be really depressing
[19:10:53] <MrHindsight> this is the stuff I'd see at the hackerspaces
[19:13:38] <zeeshan|2> guys i9ve seen this video before
[19:13:42] <zeeshan|2> where someone is moving the spindle on a lathe
[19:13:45] <zeeshan|2> and the Z axis moves along
[19:13:52] <zeeshan|2> i'm not sure how to test :p
[19:14:00] <zeeshan|2> i have all my encoder stuff working
[19:14:04] <zeeshan|2> and im about to test g33
[19:16:05] <zeeshan|2> so im gonna do g33 z-1. k.0625 as in the manual
[19:16:19] <zeeshan|2> so if i put a dial indicator, i should only see 1" movement on the dial indicator
[19:16:26] <zeeshan|2> over 16 turns
[19:47:01] <MrHindsight> ok, so there is one jumper on the http://www.automationtechnologiesinc.com/products-page/breakout-boards/kl-db25-breakout-board to separate 5V on the LPT side of the optos to VCC on the other side, but I don't see any way to isolate the grounds
[19:47:54] <MrHindsight> still 16V rating on the caps so 12V logic max on the diode side of the optos
[19:48:24] <MrHindsight> I guess you could swap the caps for a higher voltage to go 24V
[19:48:46] <MrHindsight> still a common ground though to both sides
[20:17:46] <jfigie> MrHindsight: even if the grounds are not separated you may still be OK. I think It is pretty normal to have grounded I/O power supplies for industrial controls. You just need to make sure you have really good low impedance grounds.
[20:25:01] <Tom_itx> ot.. anybody use a surface?
[20:25:51] <jfigie> surface plate?
[20:26:05] <Tom_itx> ms surface
[20:26:39] <XXCoder> Surface tablet? ;)
[20:27:18] <ssi> I use surfaces for all sorts of stuff
[20:27:22] <ssi> writing, eating dinner...
[20:27:23] <ssi> etc
[20:30:18] <XXCoder> walking...
[20:31:36] <zeeshan|2> WOOHOO
[20:31:38] <zeeshan|2> threading works
[20:31:42] <ssi> woohoo! :)
[20:32:04] <zeeshan|2> making metric threads
[20:32:09] <zeeshan|2> with an inch base system sux :P
[20:32:13] <ssi> yep
[20:32:15] <zeeshan|2> i need to learn how to g-code properly
[20:32:24] <zeeshan|2> cause i should be converting the machine units to mm
[20:32:25] <zeeshan|2> not inches
[20:32:55] <ssi> I wrote an iphone app a couple years ago that allowed me to specify arbitrary UN threads and it'd give me depth of cut information to cut it perfectyl either manually on a 60 degree compound or CNC without
[20:33:05] <ssi> I never got around to doing the metric thread module for it
[20:33:08] <ssi> I should dust that code off
[20:33:23] <zeeshan|2> what i need to figure out
[20:33:30] <ssi> but it was great for doing stuff like rifle receiver threading, doing 0.010" oversized threads
[20:33:37] <zeeshan|2> is how to write a custom subroutine for siemens nx
[20:33:40] <ssi> so I could punch in 1.076-16 and it'd do the math for me
[20:33:44] <zeeshan|2> so it outputs the correct g33
[20:36:05] <zeeshan|2> https://www.youtube.com/watch?v=7vePhuVR3Lc
[20:36:15] <XXCoder> lol
[20:36:48] <XXCoder> wish I had lathe, would be cheaper to make bolts I need.
[20:37:02] <zeeshan|2> remember, lathes are useless
[20:37:03] <zeeshan|2> ?!
[20:37:03] <zeeshan|2> :D
[20:38:48] <XXCoder> heh
[20:39:18] <zeeshan|2> i really need a iscar thread+grooving tool
[20:39:20] <zeeshan|2> er
[20:39:24] <zeeshan|2> grooving + turning tool
[20:39:59] <jfigie> Nice video so if you use G21 wont you get metric threads?
[20:40:47] <zeeshan|2> well that will allow your program to be written in metric units
[20:41:04] <zeeshan|2> but the DRO is still in inches
[20:41:20] <zeeshan|2> so its a little confusing when you're trying to touch off the part
[20:41:38] <zeeshan|2> it'd be easier just to have a cam program do all the conversions
[20:41:41] <jfigie> but you can change the DRO from inch to metric
[20:42:09] <zeeshan|2> dont you have to modify the ini to do that?
[20:42:24] <jfigie> are you using axis
[20:42:28] <jfigie> ?
[20:42:29] <zeeshan|2> yes
[20:42:37] <jfigie> it is in the menu
[20:42:47] <jfigie> I do it all the time
[20:42:49] <zeeshan|2> okay, then writing in metric makes more sense!
[20:42:50] <zeeshan|2> :)
[20:43:15] <jfigie> but I don't have a lathe yet
[20:43:29] <ssi> XXCoder: https://fbcdn-sphotos-g-a.akamaihd.net/hphotos-ak-xaf1/v/t1.0-9/427402_795224676922_1395450746_n.jpg?oh=f5a3ed59e3ea67c90206de5218ebdca6&oe=54328BC6&__gda__=1410605025_ccb6993d1861ffc1124be080a7511a68
[20:43:36] <ssi> ew what a url
[20:43:37] <ssi> haha
[20:43:45] <zeeshan|2> that looks like a 1mm thread?
[20:43:45] <zeeshan|2> :)
[20:43:49] <XXCoder> nice
[20:43:57] <ssi> nah I think it's 1/4-28
[20:44:01] <ssi> I just didn't have on hand what I needed
[20:44:13] * zeeshan|2 is looking forward to making titanium bolts
[20:44:13] <zeeshan|2> !
[20:44:19] <ssi> comment I put on that picture: "When you desperately need a ten cent screw that you can't get right now, you are suddenly very glad to have a fifty thousand dollar machine shop."
[20:44:56] <ssi> https://scontent-a-mia.xx.fbcdn.net/hphotos-xaf1/t1.0-9/404679_780071893222_1375393474_n.jpg
[20:45:03] <ssi> rifle barrel I turned, threaded, and chambered from a blank
[20:45:52] <ssi> https://scontent-a-mia.xx.fbcdn.net/hphotos-xfp1/t1.0-9/303191_725209428042_2131740446_n.jpg
[20:45:55] <zeeshan|2> very cool
[20:45:56] <jfigie> so the blank was already riffled?
[20:46:01] <ssi> that's how to set up a rifle receiver to recut the threads and lugs
[20:46:06] <ssi> jfigie: yeah... rifling is not trivial
[20:47:38] <ssi> best bet is to buy a barrel blank that's already profiled too, because turning the profile is very hard
[20:47:52] <ssi> need a controlled or hydraulic follow rest or else they whip and chatter real bad
[20:48:55] <jfigie> makes sense I have not seen a controlled follower rest
[20:49:22] <ssi> https://scontent-a-mia.xx.fbcdn.net/hphotos-xfp1/t1.0-9/408793_770310160812_1144829503_n.jpg
[20:49:33] <ssi> turning a muzzle thread on 0602 using a steadyrest
[20:49:49] <ssi> cut an AR15 barrel down to 9.5"
[20:50:36] <ssi> lathes are fun :)
[20:50:57] <jfigie> yes I am getting ready to retro fit one
[20:51:06] <ssi> I've retrofit two lathes now
[20:51:14] <jfigie> clausing 14/50 NC
[20:51:22] <ssi> nice
[20:54:38] <jfigie> I am the third person to buy this lathe for retrofitting I plan to succeed.
[20:55:12] <jfigie> There are no controls. but the ways and ball screws look like the lathe has never been used
[20:55:52] <XXCoder> lol ssi
[20:56:23] <jfigie> paint on the bed chip pan etc is un scratched. Just covered with dirt
[20:57:37] <jfigie> DC servo motors work. I need to find some suitable servo drives.
[20:57:40] <XXCoder> http://www.govliquidation.com/auction/search?cmd=results&lvl1=7&lvl2=3416
[20:57:47] <XXCoder> $0 cheap lol
[20:58:05] <XXCoder> oh its bidding, still havent opened
[20:58:57] <ssi> http://www.ebay.com/itm/131228873143
[20:59:02] <ssi> go buy my mom's truck
[20:59:24] <XXCoder> sure. hey mind paying me $20,000 to help me buy it?
[20:59:29] <ssi> lul
[21:02:13] <XXCoder> lol https://seattle.craigslist.org/tac/tls/4533279949.html
[21:02:40] <ssi> hahaha
[21:02:52] <XXCoder> it'd be great pen lathe though
[21:04:10] <jfigie> wife wants more room in garage? really?
[21:05:13] <zeeshan|2> haha
[21:05:19] <zeeshan|2> clearly he doesnt know how to deal with awoman
[21:05:33] <XXCoder> wtf https://seattle.craigslist.org/tac/for/4514824271.html
[21:05:33] <jfigie> you cant even get a car in my garage. Fortunately she has her own garage.
[21:05:42] <XXCoder> its a lathe too?
[21:06:03] <ssi> um
[21:06:10] <ssi> looks like a buffer to me :P
[21:06:14] <jfigie> liberal definition
[21:06:45] <XXCoder> got a stupid? idea.
[21:06:56] <XXCoder> buy one of those, modify it into lathe one end type
[21:07:20] <jfigie> or maybe a problem translating buffer to English
[21:09:33] <XXCoder> maybe
[23:49:26] <PetefromTn> evening folks!
