[01:13:58] <Arduno> Hi
[01:15:49] <Arduno> Hello All
[02:28:20] <mrsun> hmm, thinking of buying double the strength steppers just to be sure they can drive the mill good =)
[02:28:45] <mrsun> these can at low speeds (1.85Nm steppers) so maybe a couple of 3Nm could kick the mill into some higher speeds :P
[03:38:44] <archivist> larger steppers can be slower
[04:09:38] <Loetmichel_> mrsun:: @ 3Nm i would consider brushed servos.
[04:10:04] <Loetmichel_> MUCH more dynamic, not much mor expensive.
[04:10:06] <Loetmichel_> +e
[04:29:48] <mrsun> archivist, well compared to about 200mm/min i think they would go a bit faster, same frame also =)
[04:31:03] <archivist> higher torque also means higher inductance of the motor coils and that reduces the maximum rpm of the motor a bit
[04:32:17] <mrsun> archivist, yeah
[04:32:19] <mrsun> true =)
[04:32:27] <mrsun> but minimizes the risk for stalling also =)
[04:32:40] <mrsun> that is stalling at lower speeds .. :P
[04:32:44] <archivist> I agree that a lot of the sellers dont quote max rpm where the torque is at a minimum too
[04:32:46] <mrsun> the only problem realy is the rapids
[04:32:56] <mrsun> kinda booring to wait on rapids that is going 100mm/min :P
[04:34:28] <archivist> also increase supply voltage will give a better top speed
[04:35:03] <mrsun> yeah, but with my motors according to the geckos calculations im almost at top voltage
[04:35:06] <mrsun> 40V
[04:36:42] <archivist> are you just accelerating too fast
[04:37:12] <mrsun> archivist, might be also =)
[04:38:01] <mrsun> 40.47 is the maximum voltage im allowed to feed them :P
[04:38:17] <mrsun> or its the optimal
[04:38:22] <mrsun> and im at 40 .... close enough :P
[04:39:32] <archivist> voltage is ok
[04:39:44] <mrsun> i guess i could tinker with the acceleration stuff
[04:39:53] <archivist> try slower acceleration but higher max speed
[04:40:24] <archivist> must deal with my car MOT
[06:36:54] <Jymmm> When buying a car, is there much of a difference between (lets say ) 20K and 30K miles versus 25K and 50K miles?
[06:37:31] <archivist> non run in yet
[06:37:35] <archivist> not
[06:37:46] <Jymmm> When looking thru classifieds that is.
[06:38:20] <Jymmm> archivist: Ok, I can see that.
[06:38:42] <Jymmm> 50k and 75K ?
[06:38:44] <archivist> mine has 185k on the clock
[06:39:30] <archivist> and must dash soon, it is booked in for its annual test at 1pm
[06:40:00] <Jymmm> http://i44.tinypic.com/6tn5kw.jpg
[06:40:47] <Jymmm> archivist: annual test meaning smog check?
[06:42:02] <archivist> they check all safety items, emissions is only part of the test
[06:42:11] <Jymmm> ah, ok.
[06:42:28] <Jymmm> do they put it on a dyno?
[06:44:04] <archivist> rolling road to test brakes
[06:45:18] <Tom_itx> or 2k with no oil?
[06:45:25] <Tom_itx> all depends on maintenance i think
[06:45:51] <Jymmm> In Calif, then even pressure test the gas cap. Toss it on a dyno, and plug into the computer to test emissions.
[06:46:17] <Jymmm> But, no safety checks of anything.
[06:47:02] <Jymmm> Other than if the CHECK ENGINE light is functional/on.
[06:47:34] <Tom_itx> that is generally done when you insert the key
[06:48:08] <Jymmm> Tom_itx: True, but some will pull the lightbulb to disable it =)
[06:48:39] <Tom_itx> you'd know something was wrong though
[06:49:15] <Jymmm> CHECK ENGINE Light on == Instant Smog Failure.
[06:49:16] <Tom_itx> i pulled the gas cap on one i was a bit afraid to remove
[06:49:21] <Tom_itx> to fuel
[06:49:30] <Tom_itx> it was under rather high pressure
[06:49:42] <Jymmm> Tom_itx: from what?
[06:49:51] <Tom_itx> i don't know, it wasn't my vehicle
[06:49:55] <Jymmm> ah
[06:50:14] <Tom_itx> i cracked the cap open and it bled off air for probably 10 sec or more
[06:50:48] <Jymmm> ouch
[06:50:50] <Tom_itx> i probably should have heeded the opportunity and ignited it
[06:51:00] <Jymmm> heh
[06:51:10] <Jymmm> FIRE IN THE HOLE!!!!!!!!!!!!!!!!!!!!!!
[07:06:35] <Jymmm> In looking at this
http://i44.tinypic.com/1zyzoma.jpg, if you were selling, and had 62K what would you choose?
[07:08:03] <Tom_itx> 'other'
[07:08:16] <Jymmm> Buuuuuuuuuuuuuuuuuuzzzzzzzzzzzzzzz
[07:08:23] <Jymmm> Wrong answer, try again.
[07:08:30] <Tom_itx> it hasn't reached 75k yet
[07:08:39] <Jymmm> so
[07:08:44] <Tom_itx> it may not reach 75k
[07:09:07] <Jymmm> so, which would you choose form the option given?
[07:09:10] <Jymmm> from
[07:09:46] <Tom_itx> from option 1 it sort of indicates less than so maybe 75k?
[07:10:14] <Jymmm> Ok, and if it was 26K ?
[07:10:25] <Tom_itx> 30
[07:10:55] <Tom_itx> by the time the hooptie sells it'll have 30 on it
[07:11:00] <Jymmm> Ok, so you would be "honest" in your disclosure, and not try to pick the "best looking one" ?
[07:11:49] <Tom_itx> they would be more impressed finding one with less than advertised and may consider that for the rest of the evaluation
[07:12:16] <Tom_itx> even though the wheels were bent and front glass cracked etc
[07:13:04] * jthornton thinks spammers are dumber than a trained monkey
[07:13:09] <Jymmm> From a "dumbass" perspective, and many ppl just dont read. If they have 29,000 they may see 2x,xxx and select that because it "looks close" without actually reading.
[07:14:11] <Tom_itx> hello jt
[07:14:13] <Jymmm> It's a whole Usability thing.
[07:14:31] <jthornton> morning tom
[07:14:34] <Jymmm> jthornton: Nah, it's a SpamBot thing and the developer who wrote it
[07:14:37] <Tom_itx> Jymmm, run 2 ads
[07:14:54] <Tom_itx> see which one bites
[07:15:01] <Jymmm> Tom_itx: This is more a usability study
[07:15:14] <jthornton> I don't think so Jymmm it has capticia or what ever it is called
[07:15:48] <Jymmm> jthornton: Captcha's anymore are easily bypassed, the newest thing that seems to work is a simple question now.
[07:15:49] <Tom_itx> what has happend in my absence?
[07:16:39] <Jymmm> jthornton:
http://www.zdnet.com/blog/security/inside-indias-captcha-solving-economy/1835
[07:16:57] <jthornton> my water pipe broke at the pit-less adapter :/
[07:17:14] <Tom_itx> funny, my sewer pipe broke yesterday
[07:17:21] <Tom_itx> in the wall
[07:17:22] <Jymmm> pit-less adapter? what's that?
[07:17:29] <Jymmm> Tom_itx: Ewwwwwwwwwwwwwwwwwwwwwwwwww
[07:17:33] <Jymmm> tinky!
[07:17:39] <Tom_itx> kitchen
[07:17:46] <Tom_itx> not quite as bad
[07:17:47] <jthornton> it goes through the well casing
[07:18:09] <Tom_itx> brass adapter where the pump attaches
[07:18:10] <Jymmm> jthornton: what's a well casing?
[07:18:16] <Tom_itx> plastic pipe
[07:18:29] <Jymmm> Tom_itx: plastic froze?
[07:18:33] <Tom_itx> a pump is dropped in
[07:18:37] <Tom_itx> apparently
[07:18:46] <Tom_itx> not any water in it though
[07:18:55] <Jymmm> Tom_itx: At what level in the ground?
[07:19:03] <Tom_itx> must have been the expansion contraction over the years
[07:19:25] <Jymmm> oh nm. you said in wall
[07:19:26] <Tom_itx> Jymmm, which are you talking about?
[07:19:34] <jthornton> a well casing is a steel pipe that goes into the ground and holds the dirt back
[07:19:46] <Jymmm> jthornton: ty
[07:19:48] <Tom_itx> jt's pitless adapter is brass
[07:20:06] <Tom_itx> with a mating part to attach a pipe to
[07:20:12] <jthornton> http://www.catskillhouse.us/blog/files/paulthurst41_pitless_adaptor.jpg
[07:20:22] <Tom_itx> the well pump pipe attaches to it
[07:20:31] <Jymmm> jthornton: I thought you wee on swamp land, you can have a water well there too without the concern of containination?
[07:20:40] <jthornton> the pump and pipe hang on the left part and the right part goes through the casing
[07:20:40] <Jymmm> s/wee/were/
[07:21:04] <jthornton> I'm on a hill
[07:21:13] <jthornton> swamp to the east of me
[07:21:26] <jthornton> and Ark is to the south
[07:21:41] <Tom_itx> you didn't loose the pump did you?
[07:21:44] <Jymmm> and water level of well is where?
[07:21:51] <Tom_itx> alot of ppl tie a rope to the pipe
[07:22:16] <jthornton> no it broke on the outside
[07:22:22] <Tom_itx> ahh
[07:22:42] <Tom_itx> i helped a friend fix one that sprung a leak midway down the well of all places
[07:22:56] <jthornton> rains stopped but that part of the hill stayed wet so I had a hmmm moment then got a shovel
[07:23:12] <jthornton> then I got a big yellow shovel...
[07:23:16] <jthornton> then it got dark
[07:23:35] <Jymmm> LOL... BIG yeallow shovel, that's retty good
[07:23:56] <Jymmm> jthornton: We need to get you some BIG ASS SPOT LIGHTS
[07:24:15] <Jymmm> or as you put it... big yellow flashlight
[07:24:49] <jthornton> yea, a big one for sure 12,500 lbs without me sitting on her
[07:25:26] <jthornton> http://www.tractordata.com/backhoe-loader/000/0/0/2-john-deere-310a.html
[07:25:36] <Jymmm> jthornton: A couple of these should do ya...

[07:26:21] <jthornton> don't need water that bad to work after dark... I just used some of my RO beer water
[07:27:21] <Jymmm> As long as you're not driving and take a abth in it before hand.
[07:27:24] <Jymmm> bath
[07:32:57] <Jymmm> Which looks better/ makes more sense/ less confusing / more intuitive/ etc... a)
http://i44.tinypic.com/1zyzoma.jpg or b)
http://i43.tinypic.com/35cr87c.jpg
[07:34:03] <Jymmm> Think slimeball, dumbass when looking at them too.
[07:35:41] <Tom_itx> a
[07:36:38] <Jymmm> Tom_itx: Is that from a SELLER or BUYER perspective?
[07:36:59] <Tom_itx> observer
[07:38:52] <Jymmm> I'm just not sure. If a seller bad a car with 74,999, would he choose 50K becasue it's not 75K, and would a buyer choose 50K, thinking 25,001 to 49,999 ?
[07:39:25] <Jymmm> s/bad/had/
[07:40:22] <Jymmm> That's potentially a 50K difference.
[07:45:31] <SWPadnos> just put the range on all the lines
[07:45:34] <SWPadnos> 0-999
[07:45:37] <SWPadnos> 1000-4999
[07:45:42] <SWPadnos> 5000-9999
[07:45:44] <SWPadnos> etc
[07:46:04] <SWPadnos> and "over 200,000" or "200,000 or more" for the last one
[07:46:23] <SWPadnos> Jymmm, ^^
[07:46:26] <SWPadnos> see ya
[07:46:27] <Jymmm> Yeah, that makes the most sense. TY
[07:46:30] <SWPadnos> sure
[07:46:33] <SWPadnos> see ya :)
[07:46:39] <Jymmm> SWPadnos: Bu Bye
[07:51:00] <Jymmm> SWPadnos: Hmmm, the only catch to that is if a buyer is milling to look at cars that have "50K or less" they may be locked into 25,001 - 50,000 and not see the one at 24,999
[07:51:12] <Jymmm> s/milling/willing/
[07:52:10] <Jymmm> Maybe I need to have two different mileage charts - one for seller, one for buyer.
[08:06:43] <jdhNC> "up to xx miles"
[08:09:11] <Jymmm> jdhNC: I like it.
[08:12:24] <Jymmm> jdhNC:
http://i41.tinypic.com/25qabte.jpg
[08:16:14] <jdhNC> 20,40,60,100,150,200
[08:16:56] <Jymmm> I'm missing 40K, but other than that?
[08:17:35] <jdhNC> you don't need 1,5,10,15,25,30, etc
[08:18:05] <Jymmm> Think motorcycle as well
[08:18:10] <alex_joni> bike?
[08:18:30] <jdhNC> why would you mix bikes and cars
[08:18:32] <alex_joni> kick scooter?
[08:18:33] <Jymmm> 25K on a MC is like 100K in a car =)
[08:18:46] <jdhNC> the market doesn't overlap
[08:18:52] <jdhNC> http://www.jeffgordonchevy.com/used-cars.aspx
[08:19:03] <jdhNC> they have good pick lists (mileage, price, etc)
[08:19:14] <alex_joni> dandy horse?
[08:20:03] <Jymmm> alex_joni: wth is that?! lol
[08:20:31] <alex_joni> http://en.wikipedia.org/wiki/Dandy_horse
[08:21:00] <Jymmm> alex_joni: LOL
[08:23:50] <Jymmm> alex_joni: that's just Dandy
[09:25:12] <mikegg> http://vimeo.com/6699835
[09:25:22] <mikegg> this guy cuts cast iron like its butter
[09:32:44] <awallin> no flood coolant for demos is nice..
[10:07:20] <mikegg> awallin: you converted a gibbed machine to linear ways, right?
[10:07:29] <mikegg> http://www.ebay.com/itm/IKO-LINEAR-WAY-LWHS15C2R1800B-A-LR-MARK-7-8-CT018-0026-/160496828416?pt=LH_DefaultDomain_0&hash=item255e5b4000#ht_500wt_1180
[10:07:34] <mikegg> i've got the itch
[10:07:40] <mikegg> gibbed ways suck
[10:09:16] <mikegg> I think I could cut those rails up into three pieces and buy 8 more blocks...
[10:09:37] <jdhNC> can you cut them?
[10:10:20] <mikegg> well, I think so. those have a special anti-corrosion coating. not sure if that would interfere
[10:10:52] <mikegg> normally you can. with like a chop saw
[10:11:50] <jdhNC> not hardened?
[10:12:06] <mikegg> there is an IKO distributor about half an hour north of Atlanta. I'd probably buy the blocks from them and ask if they would cut them for me
[10:12:15] <syyl> pretty hard
[10:12:19] <syyl> use an anglegrinder
[10:12:24] <mikegg> yeah, they're hardened. right
[10:12:27] <syyl> with a thin cutoff disc
[10:13:07] <syyl> and do a good job on deburring afterwards, or you will get problems sliding new blocks on
[10:16:39] <awallin> miegg: yes, we used 15mm iko rails. I think gibbed ways might work on big machines with heavy tables. but not on small machines
[10:18:57] <mikegg> my ways are worn, so I get a good servo tune in the middle, and high following error at the ends
[10:19:18] <mikegg> frustrating
[10:45:31] <joe9> mikegg: are you from atlanta? I am from Atlanta and am looking for someone who can do a one-off cnc job around here. wondering if you have any thoughts, please?
[10:47:12] <mikegg> how big is the part? Yeah, I live in Atlanta.
[10:47:37] <mikegg> If I can't do it, I can refer you to someone who can
[10:47:43] <joe9> mikegg, small one. 8cm x 8cm and another 10cm x 10cm
[10:48:04] <mikegg> do you have a 3d file for it?
[10:48:20] <joe9> mikegg: not yet, but, I can make one or any file, if that helps.
[10:48:25] <joe9> how much would you charge?
[10:49:17] <mikegg> I'd have to look at it. I usually charge ~$25/hr
[10:49:33] <joe9> setup costs?
[10:49:57] <mikegg> well, is it something I can easily clamp in a vice?
[10:50:15] <mikegg> or am I going to have to mill a fixture to hold it?
[10:51:00] <joe9> it has 22 holes for drilling and a cut-off portion. I think it can be clamped easily. it is a pcb, that I want cut and drilled to a specific size.
[10:51:36] <joe9> I could etch it myself or, could also add the etching to the cnc too. Don't know about that, yet.
[10:51:41] <joe9> need to figure it out.
[11:04:36] <mikegg> joe9: these guys are up on peachtree industrial
[11:04:38] <mikegg> http://www.t-tech.com/
[11:04:55] <mikegg> they might make it for you
[11:05:49] <joe9> mikegg: ok, cool. as an alternative to getting it done by you, you mean?
[11:07:18] <mikegg> yeah, I used to work there. They are probably better equipped for PCB milling. I'm still happy to take a crack at it...
[11:07:19] <joe9> mikegg: did you buy your cnc or build it?
[11:07:53] <mikegg> bought used, and overhauled
[11:08:22] <joe9> mikegg: ok, cool. do you have any suggestions for buying a small cnc machine so I can do something like that myself?
[11:08:34] <joe9> something like the QC5000
[11:08:57] <mikegg> ask them if they'll sell you a used machine
[11:09:11] <mikegg> otherwise, a taig is not bad for small stuff
[11:09:27] <joe9> what is "taig"?
[11:09:43] <bill20r3> a small benchtop mill.
[11:09:44] <mikegg> you could probably get one without the controller, and retrofit for EMC2
[11:09:48] <mikegg> err linuxCNC
[11:10:06] <joe9> that was my next question. thanks.
[11:10:33] <joe9> mikegg: I do not expect an exact answer, but, how much would something like that cost?
[11:10:49] <joe9> just for an approximation, so I know if it is within my reach.
[11:10:55] <joe9> bill20r3: thanks.
[11:10:56] <mikegg> from T-Tech?
[11:11:13] <joe9> or, anyone from that matter. something cheap
[11:11:51] <mikegg> I haven't been over there in a while. They used to have PILES of old machines lying around
[11:12:29] <mikegg> I'd offer them like $500 for a used machine without a controller
[11:12:39] <joe9> ok, thanks a lot.
[11:12:52] <joe9> i presume that will give me something like this:
http://www.taigtools.com/cmill.html
[11:13:06] <joe9> if I add the controller to it, I mean.
[11:13:20] <mikegg> well, kinda
[11:13:48] <mikegg> T-Tech's machines are a little different than Taig
[11:14:20] <mikegg> look on ebay for Taig's
[11:14:33] <mikegg> you can search closed auctions to see what they are going for
[11:15:26] <joe9> mikegg: ok, will do. "T-Tech's machines are a little different than Taig" -- Do you mean it in a good way? or, are they just different?
[11:15:40] <joe9> I think the QC3000 is good enough for me.
[11:15:50] <mikegg> they are designed strictly for machining PCBs
[11:16:02] <mikegg> so if that's all you plan to do, fine
[11:16:13] <joe9> oh, good to know. yes, that is what I plan on doing.
[11:16:25] <mikegg> Taig is a little more versatile
[11:18:23] <jdhNC> joe9: you just want a PC board cut out?
[11:18:52] <joe9> jdhNC: drilled and cut-out for now. But, would love to even just use it for cutting traces too.
[11:19:04] <joe9> then I would not have to use the etchant chemicals.
[11:19:39] <joe9> jdhNC: my pcb is 8cm x 8cm and 10 cm x 10 cm
[11:19:51] <jdhNC> you could do that with a relatively cheap router
[11:20:17] <jdhNC> 2-side? what size components?
[11:21:21] <joe9> will google up on routers. smd components.
[11:21:25] <joe9> jdhNC: single side.
[11:21:58] <joe9> jdhNC: I am having trouble with the cutting and the drilling as I am finding it hard to align the drill press with the hole.
[11:22:36] <joe9> It takes me more than a few mins just to get the alignment correct.
[11:23:10] <joe9> I am hoping that using a cnc oslt will help in this regard. The pcb also has a cut-off portion that needs to be removed.
[11:24:18] <jdhNC> have you checked online PCB houses? they are surprisingly cheap
[11:24:26] <joe9> I am using a dremel currently to remove the cut-off portion. As you can imagine, the cuts are not precise with the dremel. and I think the cnc will make it more accurate and smooth'ish.
[11:24:54] <joe9> i think they charge around $15 for 3 boards.
[11:25:06] <joe9> dorkbotx and pcb-pool, you mean?
[11:25:57] <jdhNC> whomver, there are lots of them.$15 qualifies as pretty cheap IMO
[11:27:51] <joe9> mikegg: how much would a controller cost? (approximately, just a guess) for linuxcnc?
[11:27:59] <joe9> for the QC 3000.
[11:28:01] <mikegg> uh
[11:28:32] <mikegg> you can spend as much or as little as you want
[11:29:14] <mikegg> I
[11:29:25] <mikegg> I'd use mesa gear and budget about $500
[11:29:51] <mikegg> for a power supply, stepper drivers, limit switches, 7i43....
[11:30:09] <joe9> oh, ok. $500 for just the controller, you mean? or, $500 for both the used QC 3000 + $500 for the controller.
[11:30:18] <Jymmm> If steppers...
http://www.geckodrive.com/g540-p-39.html
[11:30:22] <joe9> if I can get the QC for that price.
[11:32:09] <mikegg> what you think fellas? $500 to build a 3-axis stepper controller
[11:32:41] <Jymmm> $300 to BUY the one I linked to
[11:33:11] <mikegg> you can interface with that one through the parallel port too, eh?
[11:33:12] <Jymmm> and you get a nice breakout board, VFD, chargepump, etc
[11:33:23] <Jymmm> yep
[11:33:38] <jdhNC> you can get a g540 for $229
[11:33:38] <mikegg> I dunno, hardware stepgen > software stepgen
[11:33:44] <mikegg> I think
[11:33:49] <bill20r3> $229 now? with 4 drivers? sheesh.
[11:33:51] <bill20r3> cheep
[11:34:16] <bill20r3> that's pretty tempting, I'm tired of dealing with pololus on my reprap
[11:34:33] <Jymmm> bill20r3: and mid-band dampening too
[11:35:29] <bill20r3> my last diy machine used centent cn0142's, much nicer than the tiny-chips.
[11:37:41] <jdhNC> looks like htey are back to $239
[11:38:33] <joe9> jdhNC: do you have any specific router in mind? small enough to cut the pcb's? dremel router stand, perhaps?
[11:38:52] <jdhNC> runout on dremel usually sucks
[11:39:31] <jdhNC> might check cncworld in the pcb milling section
[11:39:45] <joe9> jdhNC: cool thanks. will do.
[11:39:57] <bill20r3> joe9, I just got a cnconabudget spindle to replace my Proxxon(like a dremel, but better). It's much quieter. Upside, it was cheap, but the downside is that it took a month to get.
[11:40:01] <jdhNC> I've seen people say the cheap chinese routers do ok. Not sure about how small you can do traces though
[11:40:05] * JT-Shop waits for the pvc glue to cure...
[11:40:19] <Jymmm> JT-Shop: 30s =)
[11:40:20] <syyl> bill20r3, you forgott, that the proxxon has good collets
[11:40:27] <syyl> steel, hardened and ground
[11:40:36] <bill20r3> yep, and 3-jaw
[11:40:47] * bill20r3 wonders if proxxon collets fit in a dremel.
[11:40:53] <joe9> jdhNC: I am not doing the traces with the router. I can use the router to cut the pcb.
[11:41:04] <joe9> can I use the router to drill holes?
[11:41:08] <bill20r3> yes.
[11:41:32] <bill20r3> you can even use the milling bit to make pilot-hole divots, it helps a lot.

[11:43:04] <jdhNC> that was my first attempt at a board... crude, but worked for what I needed
[11:43:13] <joe9> jdhNC: that is cool.
[11:43:19] <joe9> and, all that with a router?
[11:43:31] <Jymmm> joe9: This is cradek's pcb...
http://timeguy.com/cradek-files/cnc/pcb/dscn6119.jpg
[11:43:33] <jdhNC> yeah, and a 1/6" end mill
[11:43:38] <jdhNC> 1/16"
[11:43:43] <JT-Shop> 2hr for full cure
[11:43:48] <jdhNC> heh... his is much nicer!
[11:43:52] <joe9> Jymmm: that is cool.
[11:44:03] <Jymmm> http://timeguy.com/cradek-files/cnc/pcb/stepdriver2.jpg
[11:44:19] <Jymmm> http://timeguy.com/cradek/cnc/pcb
[11:44:25] <joe9> googling for cncworld takes me to a games site.
[11:44:47] <TekniQue> Jymmm: good results, I didn't think it was possible with such a huge bit
[11:44:48] <jdhNC> oops... znczone
[11:44:58] <jdhNC> or cnczone
[11:45:01] <TekniQue> 1/16" is a pretty big mill for this type of work
[11:45:10] <Jymmm> TekniQue: That's cradek's work.
[11:45:31] <jdhNC> 1/16" is huge, but that's not much of a board... and I drew it in autocad
[11:45:43] <joe9> jdhNC: thanks.
[11:46:33] <syyl> thats also milled
[11:46:35] <syyl> http://dl.dropbox.com/u/24396704/port4_1.jpg
[11:46:38] <Jymmm> 1/16" was to CUT OUT the pcb
[11:46:52] <syyl> with a v-shaped single point cutter
[11:46:54] <joe9> jdhNC: what router and mill did you use? specific models, please (if you do not mind), so I can buy them myself..
[11:47:08] <jdhNC> you don't want this one
[11:47:39] <jdhNC> it's a mostly plastic gantry router with acme screws and a roto-zip
[11:48:26] <TekniQue> Jymmm: ah, nevermind
[11:48:34] <TekniQue> what router bit was used to route it?
[11:48:43] <TekniQue> 60 degree chisel?
[11:48:53] <Jymmm> TekniQue:

[12:43:22] <jdhNC> anyone know anything about sanyo denki stepper drives?
[12:43:44] <Jymmm> Made in Japan ?
[12:44:21] <jdhNC> dunno.

[13:26:35] <skunkworks> umm yah?
[13:29:29] <joe9> Sarah Forester 502 291 6522
[13:29:29] <joe9> Laura Spaulding 502 585 9642
[13:29:38] <joe9> oops sorry wrong paste.
[13:30:00] <joe9> i have no idea why it pasted that stuff. very sorry. I might have pressed "shift-insert" oslt.
[13:30:34] <mrsun> hmm, any of them cute? ;P
[13:30:50] <joe9> i have no idea. haven't seen them.
[13:30:59] <joe9> they are nice folks, though.
[13:31:11] <Tom_itx> should we call them?
[13:31:18] <joe9> please do not do that.
[13:31:31] <mrsun> haha =)
[13:31:40] * mrsun runs for the phone .... mohhaaahaha
[13:31:43] <Tom_itx> some channels would ignore that request
[13:31:49] <Tom_itx> i think you're fairly safe here
[13:35:13] <FinboySlick> joe9: Are they cute?
[13:35:38] <joe9> FinboySlick: don't know. haven't seen them.
[13:36:33] <FinboySlick> Oh well... I'll keep it safe and settle for my mancrush on Jymmm.
[13:37:57] <FinboySlick> (he's supposed to respond now, the silence is becoming uncomfortable)
[13:38:19] <jdhNC> perhaps he's too excited to type
[13:38:27] * Tom_itx snickers
[13:38:35] <FinboySlick> jdhNC: That's what's making me uncomfortable.
[13:38:58] <jdhNC> http://www.bansuriworld.com/sites/bansuriworld/files/imagecache/400x500/photos/testimonials/laura.jpg
[13:39:02] <jdhNC> that's laura
[13:39:10] <jdhNC> in case you want to trade him in
[13:39:35] <FinboySlick> jdhNC: Did you google the phone number or something?
[13:39:48] <jdhNC> that would be creepy, wouldn't it.
[13:40:14] <FinboySlick> jdhNC: Thanks for sparing me the accusation ;)
[13:40:54] * FinboySlick hmms... 'judgement' would likely be a better word.
[13:41:16] <jdhNC> I did go to Louisville, KY once for a dart tournament though (where she teaches yoga)
[13:49:27] <joe9> guys, leave them alone.
[13:49:35] <joe9> they are nice folks.
[13:49:46] <jdhNC> and limber
[13:53:02] * FinboySlick is picking on Jymm, not on the girls.
[13:53:10] <FinboySlick> But he's too excited to respond.
[13:53:25] <jdhNC> I'm picking on joe9 for the accidental paste
[13:53:26] <JT-Shop> everyone picks on Jymmm
[13:53:58] <FinboySlick> JT-Shop: He earns it well as far as I can tell.
[14:00:09] <skunkworks> JT-Shop: did you figure out your error codes?
[14:02:27] <JT-Shop> I backed up on and went with the simple one and it almost works now
[14:04:40] <JT-Shop> the only thing it doesn't do is work...
[14:06:01] <Gromits> Should I be able to run both PYVCP and Gladevcp at the same time?
[14:08:08] <Gromits> I have an existing config with pyvcp in it. I run gladevcp and get these errors:
[14:08:14] <Gromits> (gladevcp:17069): libglade-WARNING **: Expected <glade-interface>. Got <interface>.
[14:08:16] <Gromits> (gladevcp:17069): libglade-WARNING **: did not finish in PARSER_FINISH state
[14:08:18] <Gromits> **** GLADE VCP INFO: Not a libglade project, trying to load as a GTK builder project
[14:08:19] <Gromits> Xlib.protocol.request.QueryExtension
[14:24:58] <Gromits> I can run gladevcp separately on the command line and the panel comes up, but not if i try to run it from with .ini file...
[14:38:38] <Gromits> I delete my .ui file and redid it. Now gladevcp works. Very odd since I haven
[14:39:04] <Gromits> have only used glade to build that file...
[14:54:20] <Gromits> Ah, there appears to be a bug with the Container: Layout in Glade. If I use that container then the panel doesn't show up in Axis. If I use a different container (like Vertical Box) it works fine.
[14:54:43] <Gromits> Glad I could have this conversation with myself ;-)
[14:54:59] <Gromits> It was nice chattin' with ya all.
[14:55:04] <jdhNC> glad to help.
[15:06:51] <PCW> Wow neat to be able to generate a 45 ns strobe with bit banging (6 instructions @ 133 MHz)
[15:22:47] <skunkworks> PCW: whatcha doing?
[15:24:12] <PCW> Byte bangind data to/from a Ethernet chip with an embedded 8 bit uproc in a FPGA
[15:25:29] <skunkworks> cool
[15:26:39] <PCW> Still in the bearskins and stone knives environment, need to reload FPGA for every code tweak
[15:27:51] <alex4nder-> love them bootstraps.
[15:28:20] <mrsun> gah got tools for the lathe today, and they freakin do not fit :/
[15:28:31] <mrsun> have to tilt them fully forward to even get close to the center of the workpiece ... sigh
[15:28:47] <PCW> This is pretty painful but i probably will add a UART so I can run a a little monitor
[15:29:28] <PCW> right now its HostMot2 I/O connected to LEDs
[15:31:17] <skunkworks> wow
[15:32:11] <PCW> binary debugging...
[15:32:34] <jdhNC> just like the good old days!
[15:32:42] <alex4nder-> the reason forth was invented.
[15:35:52] <PCW> We use a version of forth sometimes for this but I only have 2K of code space so its
[15:35:54] <PCW> LoaddX MyMAC
[15:35:55] <PCW> ldib E_MARL
[15:35:57] <PCW> jsr EtherWW
[15:35:58] <PCW> etc etc etc
[15:45:04] <alex_joni> PCW: cool
[15:46:49] <PCW> At least with decent macros assy lang is not too terrible though it does feel a bit like building a bridge with grains of sand
[15:48:33] <alex4nder-> yah
[15:48:50] <alex4nder-> I've done some really basic bringup.. and it's fun doing things like run a kernel out of processor cache, before RAM works.
[15:50:36] <PCW> Yeah we did a custom PPC CPU for a customer and the boot code loaded from NAND flash into the cache to start the boostrap
[15:51:24] <PCW> then probe/enable the DDR RAM and continue
[15:58:43] <skunkworks> does anyone have a simple bootstrap circuit? To run a relay or such?
[15:58:55] <skunkworks> I see a few using the 555 timer...
[15:59:14] <skunkworks> bootstrap? watchdog...
[15:59:48] <alex_joni> bootstrap the watchdog?
[15:59:55] <skunkworks> watchdog.
[16:00:02] <skunkworks> hi alex
[16:00:08] <alex_joni> hey samco
[16:00:23] <skunkworks> there was a good conversation on the email list - but none of the links seem to work
[16:00:51] <Tom_itx> thank the name change for that
[16:01:10] <alex_joni> skunkworks: what links?
[16:03:57] <skunkworks> like
http://www.wallacecompany.com/machine_shop/Shizuoka/watchdog-1a.png
[16:04:12] <PCW> What about just a simple charge pump into a low power relay or MOSFET
[16:05:53] <jarray52> Does Linux CNC work with off the shelf equipment?
[16:06:15] <alex_joni> no, just on the shelf
[16:06:17] <alex4nder-> haha
[16:06:19] <alex4nder-> jarray52: yes
[16:06:35] <alex4nder-> I took me 30 minutes to learn linuxcnc and get it working with my new mill
[16:06:48] <alex4nder-> and nothing was really custom
[16:06:57] <jarray52> alex4nder: So, I could buy a CNC mill from Ebay and then hookup Linux CNC to work with it?
[16:07:27] <alex4nder-> jarray52: yes, that is possible. will it work on a lark, without planning? probably not.
[16:07:29] <skunkworks> so - cap - into a r/c circuit - voltage across the cap is what activates the ssr or such?
[16:08:13] <skunkworks> jarray52: what kind of cnc mill? do you mean one with a dead control?
[16:08:38] <skunkworks> *voltage across the r/c cap
[16:08:41] <jarray52> skunkworks: I don't have a mill. I'm planning on buying one to use with LinuxCNC.
[16:10:32] <PCW> 2 diode charge pump, input cap much smaller than output cap (so it takes many cycles to enable output)
[16:10:33] <PCW> drain resistor across output cap. If paranoid use 2 caps in series for input cap (as a short here will enable output
[16:10:35] <PCW> with no input change if input is stuck high)
[16:18:30] <jarray52> alex4nder: In particular, I'm thinking about getting this mill and using it with LinuxCNC. Ebay typically has many other mills similar to this one. I'm wondering if they would work.
http://www.ebay.com/itm/170674537943
[16:19:29] <skunkworks> PCW: thanks. will play around
[16:20:53] <alex4nder-> jarray52: are you an experienced machinist?
[16:21:37] <jarray52> alex4nder: No.
[16:22:58] <alex4nder-> jarray52: I'm a noob myself, and knowing what I know now, I wouldn't recommend you start with a machine that large.
[16:23:14] <alex4nder-> obviously one size does not fit all
[16:23:29] <JT-Shop> jarray52: have you viewed the wiki page on supported electronics
[16:23:47] <jarray52> alex4nder: More of a C++ and python programmer. I'd like to build parts weighing between 5 and 100 pounds.
[16:24:02] <jarray52> JT-Shop: Where is it?
[16:24:14] <alex4nder-> jarray52: I would start with parts that weigh between .25 and 10 lbs.
[16:24:19] <alex4nder-> and work your way up
[16:24:33] <JT-Shop> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?LinuxCNC_Supported_Hardware
[16:26:01] <JT-Shop> looks like they might be velocity drives if so should be a fairly easy refit
[16:27:33] <jarray52> JT-Shop: I just want to check if I understand things correctly. After buying a CNC mill such as the one I linked, I need to remove the electronic controllers and then add supported electronic controllers in the supported hardware list and wire the servos/motors/other electronics to the compatible controllers.
[16:27:39] <JT-Shop> this is a good sign "Everything works and it comes with controler and lots of manuals and an extra drive."
[16:28:47] <JT-Shop> usually you need something like a Mesa 5i20 + daughter card to interface with the feedback and drives on the machine
[16:29:51] <jarray52> JT-Shop: How does Linux CNC determine the geometry of the machine?
[16:30:05] <bill20r3> you tell it.
[16:30:18] <jarray52> self measuring could be an expensive and disastrous operation.
[16:30:31] <jarray52> not to mention dangerous
[16:30:31] <JT-Shop> ??
[16:30:35] <alex4nder-> ..
[16:31:02] <alex4nder-> jarray52: have you watched any videos on any of this stuff, or hung out in any machine shops?
[16:31:04] <JT-Shop> I don't understand your statement
[16:32:01] <jarray52> JT-Shop: If one inputs the wrong geometry, the spindle could crash into the table or do something else disastrous. Right?
[16:32:28] <jarray52> alex4nder-: How would I hang out in a machine shop? I would like to do that.
[16:32:46] <JT-Shop> yes, you can program the machine to crash
[16:33:05] <alex4nder-> jarray52: machinists like beer
[16:33:18] <jarray52> alex4nder-: Good plan. =)
[16:33:21] <alex4nder-> sometimes you can tempt them with it, they will let you do things, like hang around them
[16:33:23] <syyl> and a good hunk of meat
[16:33:46] <syyl> food and beer, you are the machinists best friend...
[16:33:56] <JT-Shop> jarray52: do you have any clue as to what tooling cost for a CNC mill?
[16:34:09] <jarray52> JT-Shop: No.
[16:34:25] <JT-Shop> vises, tool holders, cutting tools etc can cost you 5k in a heartbeat
[16:34:31] <alex4nder-> yah
[16:34:46] <JT-Shop> oh and collets
[16:34:49] <jarray52> JT-Shop: For the machine I linked?
[16:34:53] <JT-Shop> yea
[16:35:13] <JT-Shop> I see a tool changer on it but don't see what type of holders it uses
[16:35:19] <syyl> for that hunk of bridgeport?
[16:35:29] <skunkworks> cool machine
[16:35:36] <syyl> looks sturdy :D
[16:35:58] <JT-Shop> my VMC uses BT30 holders
http://www.maritool.com/BT30-Tool-Holders
[16:36:32] <JT-Shop> so about $125 per holder with the pull stud
[16:36:52] <alex4nder-> jarray52: what do you want to make with it?
[16:37:29] <JT-Shop> I use these
http://www.glacern.com/gsv_690
[16:37:47] <syyl> mh
[16:37:52] <JT-Shop> crash course in milling
http://www.glacern.com/
[16:37:56] <syyl> those are not very expensive :o
[16:38:08] <JT-Shop> no, and I like them
[16:38:13] <syyl> looking good
[16:38:19] <Valen> crash and milling in the same line are scary
[16:38:28] <syyl> yeah
[16:38:30] <syyl> but it happens
[16:38:42] <syyl> and it will happen :\
[16:38:47] <JT-Shop> I have videos of both for your amusement
[16:39:11] * JT-Shop goes back to modeling the trail handle for the #1 Carriage
[16:39:12] <syyl> thats a nice, scary crash...
[16:39:12] <syyl> http://www.youtube.com/watch?v=tb1kUCb9avw
[16:39:38] <syyl> (happened on a trade show...)
[16:40:53] <alex4nder-> jarray52: you might check out taig
[16:41:25] <jarray52> JT-Shop: Thanks for the video links. I will most definitely check them out.
[16:42:11] <JT-Shop> in the privacy of my garage
http://www.youtube.com/watch?v=G4-lUNa0CpY
[16:42:26] <alex4nder-> syyl: oh shit
[16:42:55] <JT-Shop> after I got my shit together
http://www.youtube.com/watch?v=isTD6bDF_LI&feature=mfu_in_order&list=UL
[16:43:38] <alex4nder-> mill crash videos are so painful to watch
[16:43:55] <syyl> lathe crashes too
[16:44:05] <syyl> and executing one, is even more painfull :\
[16:44:10] <alex4nder-> yah. :(
[16:44:43] <alex4nder-> I was feeling like a badass the other day, and was demoing some trochoidal milling code I wrote, and broke the endmill mid demo.
[16:46:12] <syyl> but,when it works, it looks pretty cool :)
[16:46:33] <syyl> started a new project today...
[16:46:41] <syyl> http://dl.dropbox.com/u/24396704/wzw_spindel2.jpg
[16:46:48] <syyl> milling spindle with toolchanger...
[16:47:07] <syyl> direct chucking with a 6mm collet
[16:47:23] <syyl> and motor part of the spindle
[16:47:30] <alex4nder-> sick
[16:47:45] <syyl> even got the motor dissassembled ;)
[16:47:46] <syyl> http://dl.dropbox.com/u/24396704/2012-01-31_18-04-31_748.jpg
[16:48:07] <syyl> and the main shaft pressed out...
[16:49:49] <alex4nder-> rad, what're you going to use it for/with?
[16:54:29] <syyl> that spindle?
[16:54:36] <syyl> for endmills smaller 3mm
[16:57:05] <JT-Shop> neat!
[16:57:43] <JT-Shop> what are you using for pulling the collet in?
[16:58:08] <syyl> a stack of belleville washers
[16:58:14] <syyl> and pneumatics for release
[16:58:22] <syyl> but i still have to do the math there
[17:03:42] <JT-Shop> that is what my VMC uses with a double stack cylinder to release the holder

[17:06:31] <syyl> mine will be a bit smaller ;)
[17:06:59] <syyl> those look like a few thousand newtons of force...
[17:07:59] <skunkworks> I don't know exactly - but a 6ish inch cylinder pushed by 1200psi hydraulic
[17:09:07] <syyl> those springs can give incredible force...
[17:09:15] <syyl> "use the force luke!"
[17:10:00] <syyl> time to leave...
[17:10:02] <syyl> goodnight
[19:07:22] <JT-Shop> say goodnight Gracie

[19:23:56] <Jymmm> JT-Shop: ping
[20:16:52] <SWPadnos> Jymmm, for a buyer, you'd just use "up to 1000", "up to 5000", "up to 10000" ...
[20:25:01] <Lasivian> hiya
[20:28:30] <Jymmm> SWPadnos: Thanks, I'm still thinking all the possibilities =)
[20:28:37] <Jymmm> SWPadnos: How ya doin?
[20:37:36] <SWPadnos> ok
[21:06:16] <Gast608> Good evening folks - I have a question on gcode subroutines
[21:06:55] <Gast608> I am using the oword subroutine that Jeff Epler mashed up for me about 2 years ago
[21:07:42] <Gast608> I normally cut and paste code into one of the subroutines to create duplicate parts
[21:08:14] <Gast608> recently I have been playing with calling a file from in the subroutine
[21:08:28] <Gast608> it has work - mostly-
[21:08:58] <Gast608> it got cranky when I called a file with lots of gcode
[21:09:13] <Gast608> I am mostly calling small files and they will work
[21:10:10] <Gast608> Question: instead of contantly cutting and pasting into one of the suboutines, is it possible to pass the file name with the subroutine call?
[21:10:45] <Gast608> I did try to do this carefully adjusting the sub
[21:11:25] <Gast608> when I run it, my call line fails with "NEAR LINE XXX - Unknown Word Where Unary operation could be
[21:11:41] <Gast608> any suggestions?
