[00:17:56] <rue_house> whats a practical expectation for step limit on a parallel port
[00:18:10] <rue_house> 100Khz?
[00:19:05] <rue_house> trick'er treat?
[00:20:56] <Jymmm> rue_house: 20K ns or less
[00:21:28] <rue_house> hmm
[00:21:39] <Jymmm> I'll let you do the math =)
[00:22:47] <rue_house> I have a dos machine, running raw C code on a 50Mhz 386, and the limit is around 1Khz or so..
[00:23:02] <rue_house> I learned to lothe how slow steppers are :)
[00:23:28] <rue_house> longer are the days of unipolar drivers tho
[01:21:10] <pink_vampire> sounds interesting
[01:21:15] <pink_vampire> rue_house:
[01:21:49] <rue_house> yes?
[01:22:04] <pink_vampire> yes
[01:23:36] <pink_vampire> rue_house: i'm also use parallel port
[01:24:40] <rue_house> I'm working on 2 things at once, for now, I have made a parallel port to arduino adapter
[01:29:12] <pink_vampire> why do you need the arduino?
[01:30:03] <rue_house> Idont ahve emc built yet, arduino can run g*bl
[01:34:32] <pink_vampire> hoo so you feed the signals from the arduino instead of the computer.
[01:34:59] <rue_house> maybe, I must play and learn
[01:35:45] <pink_vampire> how meany axis do you have?
[01:35:53] <rue_house> just 3
[01:36:42] <pink_vampire> and you need any advanced configuration?
[01:36:58] <rue_house> no
[01:39:35] <pink_vampire> so you can use the wizard
[01:39:44] <pink_vampire> 5 min and you done
[01:39:49] <rue_house> maybe I play
[03:31:11] <Deejay> moin
[03:53:22] <pink_vampire> https://www.kickstarter.com/projects/471038177/the-motto-time-without-the-clock
[03:53:47] <pink_vampire> should I make something like that?
[04:53:36] <XXCoder> pink_vampire: lol useless but why not
[05:12:36] <pink_vampire> i need very fine endmill for that
[05:12:38] <pink_vampire> XXCoder:
[05:12:46] <XXCoder> yeah
[05:12:56] <XXCoder> smallest I ever saw was 1/32 ball em lol
[05:13:20] <pink_vampire> i have 1/32 4f
[05:14:33] <pink_vampire> but it's a flat end mill
[05:14:50] <XXCoder> wonder if thats small enough to do that watch engrave
[05:15:04] <XXCoder> maybe better to use that pointy type
[05:30:50] <jthornton> morning
[05:31:21] <XXCoder> hey
[05:31:53] <jthornton> what's up this morning?
[05:31:54] <XXCoder> too bad I didn't have time to get a orange jumpsuit, or I'd have made an class D SCP worker
[05:32:57] <XXCoder> https://www.youtube.com/watch?v=Q_VpkXd1TKA heh
[05:33:01] <XXCoder> enjoy the classic
[05:35:44] <jthornton> oh light winds today, going to fly my foamie this morning
[05:44:01] <XXCoder> cool
[07:34:49] <gregcnc> pink_vampire 500-700USD iirc
[07:55:32] <newbie5000> what do I need to run a gantry plasma cutter under linuxcnc control?
[08:01:40] <_methods> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?GantryPlasmaMachine
[08:01:44] <pink_vampire> but that price is just for the spindle without the motor and the controller
[08:01:48] <pink_vampire> gregcnc:
[08:01:52] <gregcnc> yes
[08:03:25] <pink_vampire> do you think that i can get the nsk spindle but use other motor ?
[08:03:41] <pink_vampire> or i have to use also the nsk motor
[08:03:43] <gregcnc> _methods did you still have your costume on?
[08:03:52] <_methods> hahah yep
[08:04:09] <_methods> light coat of oil and an umbrella
[08:04:44] <gregcnc> thankfully coffee is already down the hatch
[08:04:51] <_methods> hahah
[08:05:50] <pink_vampire> gregcnc:
[08:06:02] <gregcnc> i haven't forgotten about you
[08:06:16] <_methods> zlog
[08:06:41] <pink_vampire> thanks
[08:16:08] <gregcnc> http://www.artcotools.com/nsk-nakanishi-nrr2651-lever-type-spindle.html
[08:17:05] <gregcnc> they are intended ot be used with their air motor, but pocket nc used a motor
[10:42:36] <MacGalempsy> anyone making chips?
[10:43:24] <archivist> two fried eggs and chips
[10:43:31] <archivist> and beans
[10:43:40] <MacGalempsy> yum. sounds like supper of champs
[10:44:24] <Demure_> Anyone know this connector? Thought it was JST SM series, but not a fit. 6 ways, 2.5mm pitch.
[10:44:25] <Demure_> i.imgur.com/bfRXVKi.jpg
[10:44:28] <Demure_> http://i.imgur.com/bfRXVKi.jpg
[10:45:00] <MacGalempsy> archivist: business pick up at all?
[10:45:14] <archivist> not really
[10:45:54] <archivist> Demure_, could be molex
[10:49:35] <Jymmm> Demure_: got different view angle?
[10:49:47] <Demure_> I haven't seen any Molex like it so far.
[10:49:53] <Jymmm> inside the connector
[10:49:55] <Demure_> Sure, What angle do you want, Jymmm?
[10:49:59] <Demure_> Ok
[10:52:01] <Demure_> http://i.imgur.com/UOa8B9l.jpg
[10:53:03] <Jymmm> I need to see it face on inside the connector
[10:55:00] <Demure_> http://i.imgur.com/kzTtTBp.jpg
[10:55:02] <Demure_> Better?
[10:55:32] <Jymmm> yes
[10:55:33] <MacGalempsy> archivist: do you mostly stick to the clocks and gears?
[10:56:55] <archivist> and a bit of archives
[10:57:10] <archivist> and anything else
[11:05:34] <MacGalempsy> over the last few years, i've seen a few of the reprapper get rich off making and selling parts
[11:14:15] <CaptHindsight> like the sellers of picks and shovels to the gold miners
[11:15:09] <archivist> but if you still have some scruples, kinda hard to sell shit to idiots
[11:29:14] <Jymmm> PT Barnum baby!!!
[11:34:54] <CaptHindsight> Jymmm: what do you store your scruples in?
[11:39:30] <Jymmm> CaptHindsight: recyclable contianer
[11:40:00] <CaptHindsight> Jymmm: paper or plastic?
[11:46:43] <Jymmm> plastic, as it breaks down in six months under UV light
[11:47:14] <Jymmm> BASTARDS... wont sell to california http://www.sportsmansguide.com/product/index/hq-issue-outdoor-wood-stove?a=1884248 and canceled my order last ight
[11:48:31] <Jymmm> Their "escalations" dept says theri "products dept" says because it has a flue is why.
[11:48:45] <Jymmm> Well a smoker has a flue, and they sell them to Calif.
[11:55:04] <jdh> smoker is made for outdoor use
[11:55:38] <Jymmm> jdh: So is that stove..."HQ ISSUE Outdoor Wood Stove"
[12:05:39] <MacGalempsy> CaptHindsight: good analogy on the gold miners. a few guys make hotends and such.
[12:06:18] <MacGalempsy> i wonder if the makersfaire have retail spaces?
[12:10:56] <IchGucksLive> hi
[12:11:59] <IchGucksLive> Demure_: ?
[12:12:08] <Demure_> Hello?
[12:12:13] <MacGalempsy> hi
[12:12:22] <IchGucksLive> hi is this the connector from the Stepper
[12:12:33] <Demure_> Yes, correct
[12:12:54] <Demure_> It's a Japanese VEXTA stepper
[12:14:39] <IchGucksLive> so you want to build a adapter as it is a 6wire to 4 wire i think
[12:14:39] <IchGucksLive> yes ofcause
[12:15:51] <Demure_> I want to find the other side of the adapter, so I can attach it to my existing wires.
[12:15:55] <Demure_> This would save me some work.
[12:16:11] <IchGucksLive> its a JST-xh 5s
[12:16:11] <Demure_> Also allow for easy replacement
[12:16:39] <IchGucksLive> where are you USA Europ ...
[12:17:38] <IchGucksLive> http://www.ebay.com/sch/i.html?_from=R40&_trksid=p2050601.m570.l1311.R9.TR12.TRC2.A0.H0.XJSt-XH.TRS0&_nkw=jst-xh+5s&_sacat=0
[12:17:46] <Demure_> Are you sure? It doesn't have the two pins on either side like the XH series
[12:18:07] <Demure_> *on either side of the top
[12:18:24] <IchGucksLive> mesure the pinwide
[12:18:32] <Demure_> 2.5mm
[12:18:39] <Demure_> Or with of the pin?
[12:18:44] <IchGucksLive> then its not a xh
[12:18:57] <IchGucksLive> they got 2mm
[12:19:10] <IchGucksLive> then its a molex
[12:19:14] <Demure_> It looks almost identical to JST-SM, which I bought but they do not fit
[12:20:15] <IchGucksLive> http://www.reichelt.de/index.html?ACTION=446&LA=446
[12:20:17] <archivist> hirose is another connector maker
[12:22:07] <IchGucksLive> Demure_: do you got the connecting plan
[12:22:27] <IchGucksLive> as you cand see the colorcodes under the black tape
[12:22:53] <Demure_> Not really, but would that matter? The people who make the connector are probably not the ones to decide how it gets used
[12:23:23] <Demure_> I'll have a look at hirose
[12:23:33] <archivist> I would cut that connector off and wire direct
[12:23:34] <Demure_> It makes sense to be a japanese connector
[12:23:48] <Demure_> That'll be my next move
[12:24:04] <Demure_> Just figured if I could find the connector easily I'd crimp 'em and be done with it
[12:27:08] <IchGucksLive> Demure_: the vexta usily hase that one http://heimwerkermarkt-tretter.de/6wire.jpg
[12:27:38] <IchGucksLive> so yellow and white is unconnected
[12:27:52] <Demure_> Correct
[12:27:55] <IchGucksLive> but you can easy mesure it
[12:28:07] <IchGucksLive> as it is half ohm
[12:28:23] <Demure_> Thanks, I know :) I'll just cut 'em off and solder.
[12:28:51] <IchGucksLive> why going for that low torqe
[12:29:11] <IchGucksLive> its only at 1.8Nm 90oz
[12:29:32] <IchGucksLive> same size can give you 3Nm 425oz
[12:30:03] <IchGucksLive> at prived 4wire and good Amps
[12:30:10] <IchGucksLive> ,-9
[12:30:23] <Demure_> They'll be reduced by the belt 2.5 times, I have even lower motors on my lathe and have had no issues.
[12:30:29] <Demure_> I have them around and figured I'd give them a try
[12:30:35] <Demure_> I can always upgrade easily
[12:53:24] <Demure_> Also they're 240oz, not 90oz, I don't recall linking to the motor specs.
[13:00:46] <nubcake> Hello
[14:00:10] <CaptHindsight> Jymmm: how far er yah from the Oregoni border?
[14:02:32] <Jymmm> CaptHindsight: 450 miles, 150 from nevada
[14:02:34] <CaptHindsight> Jymmm: mebe whatcha needs is another shippin locashun
[14:03:07] <_methods> you're not allowed to burn things in cali now?
[14:03:15] <Jymmm> CaptHindsight: Oh yeah, already thought of that. Just going to Nevada is driving over the mountain and it's winter time
[14:03:16] <Demure_> Thanks archivist: It was a Hirose connector. :)
[14:03:17] <CaptHindsight> they are in St. Paul
[14:03:17] <_methods> the whole damn state is on fire all the time
[14:03:31] <Jymmm> CaptHindsight: They have a retail location in NV
[14:03:39] <_methods> what's a camp stove gonna do that the burning embers of the state won't
[14:03:46] <CaptHindsight> _methods: but that is organic fire and smoke
[14:03:56] <Jymmm> _methods: They are CYA since it says "wood stove", but missed the whole "OUTDOOR" part.
[14:03:58] <_methods> it's ok to vent billions of gallons of methane
[14:04:02] <_methods> but no camp stoves
[14:04:22] <Jymmm> _methods: It says "WOOD STOVE" and that's all they are seeing
[14:04:29] <_methods> lol
[14:04:32] <_methods> ermahgerd
[14:04:37] <_methods> wood stove!!!!!!
[14:04:47] <Jymmm> I already called the local AQMD, they dont have an issue iwth it.
[14:05:03] <Jymmm> _methods: Non EPA stove are restricetd sales
[14:05:43] <Jymmm> Had it said "cmap stove" or "tent stove" it be no problem
[14:05:53] <_methods> ah
[14:06:06] <CaptHindsight> critter kooker
[14:06:18] <_methods> makes sense....like dog yoga
[14:06:36] <Jymmm> CaptHindsight: thats acceptable too. the AQMD hads no issue with wood cooking devices
[14:06:53] <_methods> need to build that wall around california not mexico
[14:07:35] <Jymmm> Nah, just shoot all the dumbasses that want to regulate everytihng.
[14:07:42] <_methods> i'll have to talk to the donald about getting that addition built
[14:08:00] <CaptHindsight> we need to file suit against Califor nye aye fer all its fire pollutin
[14:08:10] <Jymmm> _methods: did you get a permit to tlak about getting an addition?
[14:08:20] <_methods> hahah
[14:08:46] <Jymmm> _methods: Sadly, that really is not far behind
[14:08:50] <_methods> yeah did you guys get a permit to light your state on fire every year lol
[14:09:05] <_methods> back charge you
[14:09:14] <_methods> too bad you're broke
[14:09:53] <CaptHindsight> _methods: did they finish installing the lower abdomen body scanners (crotch cams) outside all the bathrooms yet?
[14:10:05] <_methods> i don't live in cali who knows
[14:10:11] <_methods> you'll have to ask Jymmm
[14:10:43] <_methods> Jymmm: had those installed voluntarily years ago
[14:10:50] <_methods> and he has the criminal record to prove it
[14:10:56] <CaptHindsight> lol
[14:11:11] <_methods> hahah
[14:13:37] <CaptHindsight> howza supplier done supposed to know what kin be shipped to CA and what kant?
[14:16:03] <Jymmm> CaptHindsight: THAT, I'm still trying to find out myself, as well as the actual regulation/status that they are "conforming" to.
[14:16:14] <Jymmm> statue*
[14:21:56] <CaptHindsight> Jymmm: does California still have the "agricultural" checkpoints on the highways?
[14:25:50] <Jymmm> CaptHindsight: I think all states do. There is one on the Arizona side too.
[14:26:10] <Jymmm> at least on I10 that is.
[14:34:37] <jdh> they are trying to save your life
[14:34:38] <IchGucksLive> hi
[14:34:55] <Jymmm> jdh: Ha!
[14:35:07] <Jymmm> jdh: yur funny
[14:35:16] * jdh nods
[14:35:25] <jdh> but, reallly they are
[14:35:27] <Jymmm> jdh: https://www.youtube.com/watch?v=r_DwZfyXAXI
[14:35:55] <Jymmm> jdh: How is a OUTDOOR wood stove different that a bbq?
[14:35:56] <IchGucksLive> nubcake: hi
[14:36:07] <IchGucksLive> did you got one day off nubcake
[14:36:25] <jdh> don't confuse the issue wuth your version of facts
[14:36:44] <Jymmm> jdh: Dont split hairs =)
[14:37:21] <Jymmm> jdh: Even the local regulatory agency say's it's "ok" for use =)
[14:39:09] <IchGucksLive> i wish you a wonderfull day Gn8 im off for today
[14:57:04] <miss0r> So now, the "remake" of the beat up drillpress table is complete. before: http://picpaste.com/table_old-fLRYHdWb.jpg After: http://picpaste.com/table_new-xqAq94pY.jpg I'm pretty happy with it.
[14:57:37] <miss0r> archivist ^^ (and yes, I ran out of M6x20 bolts - one short)
[14:57:38] <miss0r> enleth ^^
[15:05:08] <miss0r> for anyone else interrested: tell me the before picture is not the worst case of drillpress table abuse you have ever seen?
[15:05:40] <_methods> definitely not the worst
[15:07:08] <miss0r> realy? The middle has been fixed with epoxy at some point. There was a hole drilled so deep, it went through the table, through the leadscrew nut, and removed a few threads on the leadscrew itself. If not just the look of it, I think this point makes it the worst
[15:08:05] <miss0r> What have you seen that you think takes the cake?
[15:08:21] <_methods> wow i've seen some real wrecked tables at auctions
[15:08:31] <_methods> imagine that over whole milling machine tables
[15:08:56] <miss0r> I cannot possibly concieve what goes through the head of people
[15:09:10] <_methods> apparently not much
[15:09:55] <_methods> it's usually the machines that were in some maintenance area where the insane maintenance guys try to "machine" parts
[15:10:26] <_methods> i would imagine the machines were probably not in the best shape to begin with
[15:10:36] <_methods> that's why they got gifted to the maintenance shop
[15:10:52] <miss0r> other great news. I just caught a mouse in a trap on the ceiling of the shop. This second. But the noise i've heard is still somewhat there. There is another one up there... FREK
[15:11:32] <miss0r> That is true. I think this was in a machine school before my dad bought it on auction some years back. Now I have it :)
[15:11:55] <_methods> yeah i've seen some school tables that were pretty bad too
[15:12:43] <miss0r> and this is not the school where you go to be a machinist. This is probally more the equevalent of 'metal shop' in a highschool
[15:24:45] <CaptHindsight> _methods: how else do you know if the hole you have drilled goes all the way through?
[15:25:03] <CaptHindsight> you might have just made a blind hole
[15:25:13] <miss0r> lol
[15:25:20] <CaptHindsight> and then the nails will bend when you hammer on them
[15:25:54] <miss0r> that is indeed a problem.
[15:26:09] <CaptHindsight> measure twice, drill once!
[15:26:24] <djdelorie> no, measure twice, use a cnc machine to drill hundreds of times...
[15:28:34] <miss0r> djdelorie: I use a another system "measure twice, setup CNC. Acknowledge error, measure again, everything seems right, but the parts does not fit. Have a cold beer and go to bed" - method
[15:29:03] <djdelorie> oh sure. Don't we all have a large collection of "art" in our shops?
[15:30:12] <miss0r> In danish we use the same word for subject(as in human subject/person of interrest) and workpeice. I have a box labeled "suspect subjects" with all kinds of paper weights in it :)
[15:30:28] * djdelorie once worked at a hybrid facility that was built because of the difference between "fits on paper" and "fits during assembly"
[15:31:47] <djdelorie> apparently, it was important for the manufacturing folks to drag an engineer down, point at a machine, and yell "Fine! YOU make it fit then!"
[15:36:06] <andypugh> djdelorie: Odd, my place of work was moved 20 miles away from the manufacturing plant to stress “how important is it _really_ to get the engineer down here awau from his job to sort out your technical issue”
[15:36:42] <djdelorie> I didn't say that facility lasted very long ;-)
[15:40:59] <andypugh> This is that G-code I was talking about last night in action: https://www.youtube.com/watch?v=7swEpeDI36g
[15:41:54] <Deejay> is it POM?
[15:42:03] <andypugh> It’s a candle :-)
[15:42:15] <Deejay> lol
[15:42:18] <Deejay> ooooookay ;)
[15:42:24] <Tom_L> what you makin andy?
[15:42:48] <andypugh> I used a candle because a tool-crash (probbaly) won’t break the tool.
[15:43:15] <andypugh> And I would rather mess up a re-meltable candle than a £50 lump of brass.
[15:43:16] <Tom_L> right
[15:43:56] <andypugh> It’s going to be part of a needlessy-elaborate clock.
[16:11:05] <zhivko> Hi guys!
[16:11:35] <zhivko> Is there some good instructions how to calculate feeds for g93 mode?
[16:11:53] <zhivko> I want to do this move on 4 axis cnc:
[16:12:00] <andypugh> Its basically just maths.
[16:12:16] <zhivko> G01 X-0.000 Y180.000 Z106.353 A-0.000
[16:12:16] <zhivko> G01 X0.891 Y29.990 Z106.353 A270.000
[16:12:28] <andypugh> You need to work out the distance of each move, then work out how long that should take
[16:12:47] <zhivko> so x,y,z are almost same point but rotational axis changes from 0 to 270 degrees
[16:12:58] <zhivko> yes this is problem
[16:13:12] <zhivko> if x,y,z are practically same distance is 0
[16:13:13] <andypugh> The answer can’t be calculated without knowing where the ais of roation is.
[16:13:20] <zhivko> and then I get HUUUGE feed rate
[16:13:42] <zhivko> axis of rotation in my case is y axis
[16:13:58] <andypugh> But where on the Y axis?
[16:14:30] <zhivko> so basically I am developing this plasma pipe cutter - so rotation is always whole Y axis
[16:14:38] <zhivko> so basically I am developing this plasma pipe cutter - so rotation axis is always whole Y axis
[16:14:54] <andypugh> Is it valid to assume that the axis of rotation is always at Y=0?
[16:15:48] <zhivko> yes exactlyy
[16:17:13] <zhivko> @andy hmm... how do you mean y=0, you need axis and axis is not defined by just one coordinate
[16:17:27] <zhivko> so axis of rotation is Y axis...
[16:17:27] <andypugh> OK, so your total travel distance is approximately (2.pi/360)*dA = dY + dX + dZ
[16:17:59] <andypugh> Sorry, (2.pi/360)*dA*Y + dY + dX + dZ
[16:18:43] <zhivko> hm... why *Y ?
[16:18:59] <andypugh> Because that’s the radius of motion
[16:19:12] <zhivko> i thought it should be sqrt(x^2 + z^2) ?
[16:19:29] <andypugh> It should, if you are being exact
[16:19:36] <zhivko> no, rotation A rotates around Y
[16:19:53] <zhivko> and radius that rotates is defined by x and z coordinate
[16:20:10] <andypugh> But we aren’t even considering which _direction_ A is turning relative to the other moves, so adding Pythagarous in seems a bit over-keen
[16:20:20] <andypugh> Oh
[16:21:21] <andypugh> Maybe you need this? https://www.youtube.com/watch?v=d0ffiCekhpE
[16:21:22] <zhivko> an dI think it should be: + sqrt(dY^2 + dX^2 + dZ^2) - isnt it ?
[16:22:17] <zhivko> an dI think it should be: (2.pi/360) *dA * sqrt(x^2 + z^2) + sqrt(dY^2 + dX^2 + dZ^2) - isnt it ?
[16:22:35] <andypugh> Sounds about right.
[16:23:32] <zhivko> OH yea... I will try it... thanks Andy!
[16:24:11] <andypugh> It has the advantage that it exists, and will modify your G-code.
[16:24:30] <andypugh> It’s not 100% perfect for you, but could probably be modified.
[16:24:45] <zhivko> I am generating my own gcode - so I need to alter my code
[16:38:26] <zhivko> andy: hmm.. the * sqrt(x^2 + z^2) part - x and z should be from first (before rotation) or last point (after rotation) ?
[16:40:03] <andypugh> Yes, you need to keep track of where you are moving to, and where from.
[16:40:14] <djdelorie> and along which path
[16:41:41] <pfred1> I wish i knew where cmake plans on installing to
[16:42:50] <zhivko> So I have both points - which one to use? it seems any of them have same radius - right? so I can use any of them
[16:43:40] <djdelorie> it helps if you think of the surface you're moving along as "unrolled" from the part - the radius changes the distance around the circumference but not the distance along the axis
[16:43:55] <djdelorie> and rotation likewise only changes the distance around the circumference
[17:02:32] <nubcake> http://www.ebay.de/itm/Drehbank-Frasmaschine-Leitspindeldrehmaschine-Premium-6133-400V-1-1-kW-NEU-25047-/391216719534?hash=item5b165566ae:g:rKMAAOSwImRYDgsl anyone knows if this thing's any good at all or just overpriced? never heard of that manufacturer before.
[17:06:58] <andypugh> Stabilo? I think I have actually heard of them, but not as a lathe maker.
[17:07:22] <andypugh> https://en.wikipedia.org/wiki/Schwan-Stabilo
[17:07:42] <andypugh> The lathe might work well for sharpeening pencils :-)
[17:08:59] <andypugh> It looks a bit better than the other lathes of that class. A locking handle for the tailstock is nice, but it is still a very tall, narrow tailstock.
[17:11:05] <andypugh> nubcake: Does it have power cross-feed? That would be unusual and rather “premium” in the class.
[17:29:19] <Flipp_> anyone know of a supplier for spur gear stock?
[17:29:43] <Deejay> gn8
[17:30:13] <Tom_L> stp-si
[17:30:20] <Tom_L> sdp*
[17:32:28] <Tom_L> http://www.sdp-si.com/products/Gears/Index.php
[17:32:40] <Tom_L> 3/4 down
[17:40:20] <andypugh> Flipp_: http://www.hpcgears.com/n/products/15.toothed_bar_stock/toothed_bar_stock.php
[17:41:17] <Flipp_> tom_l and andypugh: thanks! hard to find that stuff O.o
[17:41:48] <andypugh> If you have a LinuxCNC mill, you can make your own gears.
[17:42:05] <Flipp_> now here's another hunt I've been on: *internal* spur stock (e.g. for the ring gear in a planetary setup)
[17:42:26] <andypugh> Hmm, that’s harder to make your own too
[17:42:38] <Flipp_> yeah
[17:42:55] <Flipp_> andypugh: yeah, I've got a g0704, but it's manual (for now)
[17:43:01] <Flipp_> will eventually convert it
[17:43:22] <andypugh> HPC do internal gears too, but not long lengths: http://www.hpcgears.com/n/products/6.internal_gears/internal_gears.php
[17:43:47] <archivist> I did a model for someone to laser cut internal gears
[17:44:04] <andypugh> I was wondering about suggesting that
[17:44:17] <archivist> shaping for random gear length
[17:44:48] <archivist> Flipp_, what size?
[17:45:19] <Tom_L> sdp may have that too
[17:45:48] <andypugh> Yeah, HPC may be inconveniently in the UK. But then we have no idea whaere you are?
[17:46:26] <Flipp_> archivist: something along this size: http://www.banebots.com/product/P80P-GR3-SP.html
[17:46:36] <Flipp_> yeah, sorry, I'm over here in the States
[17:47:43] <Tom_L> mcmaster might have what you want too
[17:47:45] <archivist> that is probably broached if it is made in qty
[17:48:13] <Flipp_> Tom_L: checked McM. they do have a bit, but sadly no metric :(
[17:48:21] <andypugh> The weak £ might make HPC a good bet even though they are in the UK
[17:49:10] <archivist> tooling is very expensive for internal gears
[17:49:28] <Flipp_> archivist: yeah, I'm looking at broaches and they're in the hundreds :/
[17:49:36] <Flipp_> andypugh: that's... actually a good point :)
[17:49:54] <andypugh> You need a shaving machine to make internal gears properly
[17:50:22] <andypugh> (Which would be pretty easy to make from scratch and then run with LinuxCNC)

[18:09:03] <JT-Shop> hmm my weld table is in Earth City MO
[18:28:57] <nubcake> n8 everyone
[19:32:07] <zeeshan> hi
[19:50:19] <zeeshan> anyone here work with stainless a lot?
[19:50:22] <zeeshan> machining it
[19:52:33] <rue_house> oh I hyate stinless
[19:52:46] <rue_house> its soft, till you work on it
[19:52:52] <rue_house> then its harder than anything
[20:04:44] <Tom_L> zeeshan what you workin on?
[20:04:50] <zeeshan> nothing
[20:04:55] <zeeshan> trying to learn a better recipe for stianless
[20:04:58] <Tom_L> it work hardenes pretty easy
[20:05:13] <zeeshan> looks like people can get away with 5000 rpm
[20:05:18] <zeeshan> (about 400-500 sfm)
[20:05:21] <zeeshan> w/ 1/2" end mill
[20:05:29] <zeeshan> with .005ipt , 1.25" doc
[20:05:33] <zeeshan> .04-.05 step over
[20:10:56] <Tom_L> pretty health cut
[20:11:28] <zeeshan> i'd like to try some recipes on it
[20:11:47] <Tom_L> get plenty of 4flute cutters to test with
[20:11:53] <zeeshan> lol
[20:12:00] <zeeshan> im going to use the pow-r-mill
[20:12:02] <zeeshan> cutters from imco
[20:12:05] <zeeshan> im in love with their cutters
[20:12:16] <Tom_L> any coating on em?
[20:12:20] <zeeshan> tialn
[20:12:23] <zeeshan> i think
[20:12:29] <zeeshan> er pow-r-feed
[20:12:31] <Tom_L> good until you wear thru it
[20:12:58] <zeeshan> • New AlCrNX engineered coating shown to improve tool life exponentially
[20:12:59] <zeeshan> sorry
[20:13:01] <zeeshan> not tialn
[20:13:08] <Tom_L> now stop messin around with stainless and get that lathe goin!
[20:13:28] <zeeshan> duyde
[20:13:32] <zeeshan> still looking for manuals
[20:13:33] <zeeshan> :(
[20:13:38] <Tom_L> you gonna start makin headers or what?
[20:13:58] <zeeshan> ??
[20:19:36] <zeeshan> one of my part time business customers
[20:19:43] <zeeshan> (regular person i deal with)
[20:19:50] <zeeshan> gave me a whole bunch of titanium tubing scraps
[20:19:53] <zeeshan> along with titanium tig wire
[20:19:53] <zeeshan> lol
[20:20:00] <zeeshan> cause i mentioned to him a while ago that i'd love to try welding titanium
[20:23:10] <Tom_L> heh
[20:24:38] <Tom_L> did you see andy's video?
[20:24:41] <zeeshan> no
[20:24:42] <zeeshan> link
[20:25:20] <Tom_L> https://www.youtube.com/watch?v=7swEpeDI36g
[20:25:57] <zeeshan> andy is too intense
[20:25:57] <zeeshan> :P
[20:26:06] <Tom_L> very short code
[20:26:09] <Tom_L> subs
[20:26:14] <zeeshan> f that
[20:26:16] <zeeshan> cam it up
[20:26:17] <zeeshan> :D
[20:26:53] <Tom_L> good demo of what lcnc can do though
[20:29:06] <Tom_L> for a clock of some sort
[20:43:01] <pcw_home> As Andy explains CAM is dreadful if you need to change the cams (it doesn't work in cam space)
[21:57:39] <rue_house> I need to finish writing my cam program
[21:58:18] <rue_house> I'm planning on calling it amaturecam, after mastercam
[21:58:57] <Jymmm> slavecam
[21:59:04] <rue_house> oooo
[21:59:05] <Jymmm> servantcam
[21:59:25] <Jymmm> batercam
[21:59:32] <rue_house> ?
[21:59:39] <Jymmm> Master Bater
[22:00:08] <rue_house> aaaanyhow
[22:00:31] <rue_house> I can read lines and stuff from dxf files,
[22:00:34] <CaptHindsight> Jymmm: you forget to connect the stove pipe back to the outside of the house again?
[22:00:37] <Jymmm> oh, slave cam is fine, but not the thing that everyone on the planet does... uh huh.
[22:01:27] <rue_house> I cant understand why there isn't a free cam program out there that runs on linux and can pocket a 2d profile from a dxf file
[22:01:31] <Jymmm> Sorry to shock you folks, but yes, YOUR PARENTS HAD SEX WITH EACH OTHER... really, honest engine.
[22:01:43] <rue_house> and I dont know how to write code to pocket a circle
[22:02:04] <rue_house> or how to organize the stuff in a dxf into something that can be traced
[22:02:04] <Jymmm> I thought there was something to do that already built in
[22:02:08] <rue_house> but, I'll work on it
[22:02:14] <rue_house> dxf
[22:02:19] <rue_house> a 2d cad file
[22:02:25] <rue_house> not an stl
[22:02:59] <Jymmm> rue_house: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Simple_LinuxCNC_G-Code_Generators#Rectangular_Circular_Pocketing_Generator
[22:05:13] <rue_house> ...
[22:05:22] <rue_house> some of those are closer to my cam program than I am
[22:05:51] <rue_house> http://code.google.com/hosting/moved?project=dxf2gcode huh, vaporware
