kinda hard to tell without poking at it 16:15:58 it's just funny to see computers, generators, lab equipment, and wood shavings ... 16:16:51 hey, can you gouy take a look at these, and tell me what size motor you think they're for? 16:17:01 http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=7588770751 16:17:37 the motor mounting holes just don't look quite far enough apart to be NEMA42 16:18:30 yeah probably nema30 or whatever 3" is 16:18:40 34 16:18:57 they look nice, other than that 16:19:01 ok each nub on the belt is probably 0.2" 16:19:15 er, drat not 0.2" 16:19:23 could be, either 1/5" (XL), or 3/8" (L) 16:19:50 hmmm - actually, the bearings are 7204, so they're 1.85" or so OD 16:20:08 47 mm, I think 16:20:13 ack $750 for those 16:20:23 yeah - it's a great deal if they fit ;) 16:20:29 are you serious?! 16:21:08 maybe i'll get into the motor bracket business 16:21:09 yes 16:21:23 they're amazingly expensive for BP sized mills 16:21:44 you'd think people that make stuff all day would know how to make their own brackets.. sheesh 16:21:56 Anilam sells their mounts (only) for $1900 for X+Y, and $1600 for Z 16:22:07 well - chicken and egg problem 16:22:16 bah 16:22:32 birdbrain problem.. don't know how to crank the handles 16:22:42 plus, look at the amount of metal missing - I'd have to buy a block of Al that's 8x4x14, then mill away more than half of it 16:23:01 that's a lot of CNC time, and a big hunk of metal 16:23:03 you're not making a space shuttle you know 16:23:13 (the metal alone would be in the $125 range) 16:23:24 I know that 16:23:33 i would make it out of 1/2" plate and weld the guards on it 16:23:44 the bearing position needs to be very precise 16:24:40 if you mount the motor extending out from the table (for the X axis), then you need two mounting surfaces that are at least 1.5" apart, because the motor shaft is pointing in the opposite direction from the ballscrew shaft 16:25:00 so you have two plates, plus "risers" 16:25:09 plus the beraing mount 16:25:12 bearing 16:25:50 I've started a design that just attaches to the existing bearing mount, but even that's a pain, and starts out with a large block of metal 16:27:12 the motor crashes into the table if it's pointing left? 16:27:42 er, with the motor to the left of the belt/pulley when in front of the machine 16:29:42 most mounts (this one included) point the motor body away from the spindle (shaft toward the spindle) 16:30:09 I'm trying to design one that has the motor parallel to the table, and in front of it 16:31:03 it's not that easy, because it blocks the front slot, and there's not a lot of room between the table and the Y handle (if you leave it on) 16:55:33 acemi has joined #emc 18:05:06 hi. 18:07:04 les_w: there goes a VF-9 for the low low pricee of $70k 18:08:16 anyone ever made thier own spindle? 18:11:01 yeah.. i hear semi trailer taper roller bearings work pretty well for the price 18:11:11 hmmm 18:11:25 i just used bronze bushings though.. go figure 18:11:35 I'm planning on doing small stuff, so I'll need a pretty fast spindle 18:11:40 ah 18:11:52 also, those Centent stepper drivers are still at $50, if anyone needs some 18:11:55 angular contact ball bearings are prolly your best bet 18:11:56 just dont out-bid me. 18:12:27 the guy has 18 of them, I'm the only bidder so far. 18:12:41 well they ain't goin anywhere quick 18:12:51 yeah, I'm kind of suprised. 18:13:16 I got my gingery mill book, it looks pretty decent 18:14:11 i wanna tenCent stepper driver.. 18:14:27 heh. 18:14:39 if he re-lists the rest cheaper I may get an extra set. 18:15:30 any opinions on a fixed spindle ofer an X-Y table versus a moving spindler over a 'X' sliding table? 18:15:52 I'm thinking the fixed-position(except Z) spindle will be more rigid. 18:16:17 i like the van norman design 18:16:25 * bill2or3 googles 18:16:41 x/y table, knee, quill, sliding ram in Y 18:16:50 and the head swivels 90 degrees to be vertical or horizontal 18:17:10 so you can slide the ram all the way back and the knee up for extreme rigidity 18:19:07 hmm. 18:45:14 sigh.. there goes my centrifuge for $3000 18:45:22 it's not even worth $500 18:46:14 boo. 18:46:27 what do you need a centrifuge for? 18:46:32 nothin.. 18:46:49 sounds like most of the crap I buy. 19:06:30 acemi has left #emc 19:28:15 robin_sz: are you around? 20:22:45 alex_joni: no not at the moment 20:34:29 websys has quit 20:52:17 fenn halve a look for "butler elgamill" on the 'net .. sounds similar to your design 20:52:53 oh hi robin 20:53:28 wow that's big 20:53:42 actually got some prussian blue on my hands today 20:53:49 5 meter table.. 20:53:57 had to make a jacobs taper adapter 20:54:43 got it close by tapping the compound angle....then prussian blue and die stones for an exact fit 20:54:47 fenn; they come in various sizes, but the ram for the head, that swivels on a 45 degree facet is interesting ... 20:54:50 jmk had a page about the van norman 12 but it's down now.. 20:55:28 how did it come out les? 20:55:36 hey les 20:56:10 not seen yo about much .. buyt then I am rarely on 20:56:17 too much work these days : 20:56:20 ) 20:56:34 the taper adapter? blue spots on the whole surface... 20:56:36 haha 20:57:45 Well I have had a break while my piezo stuff is made over on your side of the pond 20:58:05 ok. 20:58:20 still looking good to go is it?

They have 10k pull-ups, so I should be able to just hook the collector of the darlington right to the input and ground the emitter 21:13:00 you may get false trips from humidity 21:13:29 ? think 10k is a little high? 21:14:08 we had an isolated input on one baord that only needed 2 uA to trip it 21:14:14 roughly 21:14:27 really 21:14:33 I think it was 10k or 15k pull-ups to a +15V rail 21:14:48 if you're using 24V, keep that in mind 21:14:58 I usually use about 3k or so 21:15:11 no the stg jut pulls up to +5 21:15:19 ah - ok 21:15:33 the irled will be running from 24...with a series resistor 21:15:48 using 4n33 21:15:50 10k may be all right, just be aware that you might be surprised by how little it takes to trip 21:16:04 I'll watch that 21:18:00 I had some false home trips before...and NC limits switches would need excercising once in a while or they would open up 21:18:08 that was at 5v 21:18:20 24 should mane most of that go away 21:18:24 strange that aswitch would "fail open" like that 21:18:57 well it is a wiping contact...and it never gets tripped on the limit... 21:19:13 but fail open is safe... 21:19:18 sure - that's why it seems weird for it to opn up on its own 21:19:23 the machine will go into hard e-stop 21:19:45 sure, it's the safe way, but strange for the switch to just open from time to time ;) 21:19:54 yeah 21:21:02 actually as I recall it was e-stop switches in the limit switch chain 21:21:08 big red button... 21:21:17 have them all over the machine 21:21:25 they were surplus 21:21:31 never more than arms reach away, I would hope 21:21:47 new old stock but perhaps the contacts were corroded 21:21:59 right arm's reach 21:24:54 Jymmm has joined #emc 21:25:14 heh - I was just going to complain that the one time I want to talk to Jymmm, he's not here 21:25:33 err - I mean, Hi Jymmm 21:25:39 Jymmm has left #emc 21:25:42 Jymmm has joined #emc 21:25:46 bastid 21:25:51 Hi, Jymmm 21:26:15 SWPadnos: How can I be of service? 21:26:51 well, I'm looking for tickets to SJC, and I'm wondering how long it takes to get from other area airports (SFO, OAK) 21:26:58 also how much it costs for the stupid shuttles 21:27:43 Driving from SFO/OAK to SJC w/o any traffic is about 45 minutes. 21:28:09 Shuttles, no idea. 21:28:27 hmmm - actually, I can rent a car for the week for the cost of a shuttle ride plus part of the difference in airfare 21:28:40 I think one of the shuttle sites had $115 for the RT fare 21:29:14 http://www.sjc.org/travelers/d2d.php 21:29:17 I assume those are the only airports close enough to be worth looking at 21:30:01 right - I had seen that page - though I would actually want to go to the Hilton at the convention center 21:30:33 Well SFO is in South San Francisco, Mosconi Center is in San Francisco 21:30:45 a rental car would also solve the problem of how to get into SF for the House of Prime Rib ;) 21:30:54 I'm headed for McEnery 21:30:55 South San Francisco and San Francisco are two different cities 21:31:06 in San Jse 21:31:07 Jose 21:31:26 McEnery ?
