[00:58:49] <mozmck> SWPadnos: only got 2 MPGs at the auction...
[00:59:08] <SWPadnos> cool
[00:59:31] <SWPadnos> I remembered that I actually need a part, but a little too late
[01:00:30] <mozmck> what?
[01:00:52] <SWPadnos> the hydraulic cylinder for a Johnson model J horizontal bandsaw
[01:00:58] <mozmck> I got a little tooling
[01:01:26] <mozmck> didn't get any hydraulics, but there were some there that went dirt cheap. everything did.
[01:01:34] <SWPadnos> bummer
[01:01:45] <SWPadnos> the cylinder is like $950 from Kysor Johnson
[01:01:55] <SWPadnos> which is 3x what I paid for the entire saw
[01:02:05] <mozmck> most everything. I have quite a few cylinders from various things, what size is it?
[01:02:13] <SWPadnos> I don't know exactly
[01:02:43] <mozmck> What's wrong with it? I've rebuilt a number of hydraulic cylinders successfully.
[01:03:00] <SWPadnos> well, that's a good question too :)
[01:03:07] <SWPadnos> I did replace the seals and hydraulic oil
[01:03:20] <SWPadnos> I think the valve is broken or something
[01:03:46] <SWPadnos> (it's one of those that you adjust downfeed with, and the oil gets recirculated through a no-pressure tube)
[01:04:09] <mozmck> Oh, is the valve in the cylinder?
[01:04:17] <SWPadnos> on the bottom
[01:04:57] <mozmck> I would think that should be fairly simple - can you get it apart?
[01:05:11] <SWPadnos> yes, I've disassembled and reassembled it
[01:05:35] <SWPadnos> it's been a while though, which is part of the reason I forgot I need one
[01:06:40] <mozmck> huh, so I guess it drops too fast. Seems like a valve like that would just be a small hole with a needle valve - or maybe a ball with a spring and screw to adjust the tension.
[01:07:04] <SWPadnos> it's a needle valve, I thin
[01:07:06] <SWPadnos> k
[01:07:48] <mozmck> I may keep the MPGs. got two fanuc control panels with one on each, along with joysticks and buttons etc.
[01:08:05] <SWPadnos> nice
[01:09:09] <mozmck> They had some cnc lathes there that didn't sell at $100
[01:09:14] <mozmck> needed work
[01:10:21] <SWPadnos> wow
[01:10:35] <mozmck> one roku roku vmc that didn't sell either, but it was missing some parts
[01:10:35] <SWPadnos> hmmm. maybe it was the Jabsco coolant pump that was $1000-ish
[01:10:44] <SWPadnos> the cylinder might have been only $500-ish
[01:10:50] <mozmck> still ouch!
[01:11:00] <SWPadnos> yeah
[01:11:31] <mozmck> I got one of the drive cradek was looking for and some bt-40 tooling
[01:11:43] <mozmck> but no dc stuff that I saw
[01:12:09] <skunkworks_> nice!
[01:12:30] <mozmck> My boss came down and bought a small mill that didn't sell - for $75!
[01:12:42] <SWPadnos> wow - the manual is online now: http://www.dakecorp.com/manuals/Model_J Series.pdf
[01:12:54] <SWPadnos> err, plus appropriate %20's
[01:13:04] <SWPadnos> like this: http://www.dakecorp.com/manuals/Model_J%20Series.pdf
[01:13:11] <mozmck> skunkworks_: I think there are a few cat 40 pieces in there - do you need them?
[01:13:37] <skunkworks_> our big brown and sharp is 50 taper
[01:14:07] <mozmck> ok. I don't even know what all is in that box - it's not all the same.
[01:14:20] <skunkworks_> that is the fun part :)
[01:15:03] <mozmck> If I had more money and a way to move stuff I'd have bought all the broken machines and sold parts and scrapped the rest!
[01:21:11] <mozmck> heh, here's one that might be interesting - SWEO motion controls, input 240 volts, 54 amps, output 240 vdc 66 amps rms
[01:27:12] <mozmck> SWPadnos: looks like that cylinder has a ball and spring. maybe the spring is broken or something is stuck?
[01:27:36] <SWPadnos> I think the yoke is broken actually
[01:27:53] <SWPadnos> it also doesn't hold up, so that's also a problem
[01:29:24] <mozmck> ahh
[01:29:27] <SWPadnos> ok, yes - one side of the yoke is broken, though it's the top part, so the head will still rest on it
[01:33:26] <mozmck> you interested in that SWEO unit? looks like it is a DC servo drive
[01:33:38] <SWPadnos> sounds a bit big ;)
[01:33:47] <SWPadnos> and very efficient - 66A out and 54A in
[01:35:08] <mozmck> yeah, it's big, but that's what you wanted right? more than 80v and 20a... it would be cheap if you're interested.
[01:35:28] <SWPadnos> what do you think the shipping would be to Vermont? ;)
[01:36:13] <SWPadnos> it also kind of depends on how the output voltage can be controlled - I have servos that are 160V/39A peak
[01:38:22] <mozmck> yeah, I don't know about that. it weighs right about 20lbs, so I would guess shipping at ~$25
[01:38:30] <mozmck> part number is 001-033-2
[01:38:35] <SWPadnos> I
[01:38:51] <SWPadnos> I'll have to look it up later - I should be laying out a PC board right now
[01:38:55] <mozmck> no it's 010-033-2
[01:39:12] <mozmck> me too actually
[03:21:47] <cradek> mozmck: hi!
[03:21:54] <cradek> holy crap, you found one? that's great!
[03:22:15] <cradek> I just got the drawbar and all the tool changer sensors/activators working... great progress tonight
[11:16:32] <mook> Hope everyone in channel is well and in the mood to help..........
[11:16:59] <mook> I am wondering about getting emc running on an old mmx system
[11:17:14] <mook> can anyone suggest a devel environment
[13:51:48] <alex_joni> mook: check if there's a TSC on the processor
[13:51:53] <alex_joni> otherwise I doubt rtai will work
[17:43:06] <cradek> yay, tool prep works
[17:44:04] <alex_joni> cool
[17:52:53] <alex_joni> pictures/videos?
[17:53:29] <cradek> nope
[17:53:47] <alex_joni> too bad ;)
[17:56:45] <skunkworks_> great|!
[18:04:46] <skunkworks_> are the drives still acting funky?
[18:05:24] <cradek> the only remaining drive problem is the fuse fault thing
[18:05:34] <cradek> I got good motion
[18:06:06] <cradek> just various other problems, you know how it is :-)
[18:07:02] <skunkworks_> heh - cool - and now you may have another drive from moses>
[18:07:05] <skunkworks_> ?
[18:07:20] <cradek> yes, sounds like
[18:07:29] <skunkworks_> very neat
[18:07:36] <cradek> not an exact match - but will be great to have a spare
[18:07:41] <skunkworks_> right
[18:07:42] <cradek> I think the one he found is one step bigger
[18:08:00] <cradek> need to make some lunch - bbl
[18:57:12] <micges> hello
[18:58:00] <SWPadnos> hi
[18:58:44] <micges> for exercise I've started moving iocontrol stuff to motion and I discovered something that seems to be unfinished estop functionality
[18:59:24] <SWPadnos> uh-oh
[18:59:28] <SWPadnos> (to both)
[18:59:56] <micges> on iocontrol it is message EMC_AUX_ESTOP_RESET_TYPE
[19:00:20] <micges> with comment: // doesn't do anything right now, this will need to come from GUI
[19:00:33] <micges> anyone knows sth about this ?
[19:01:37] <alex_joni> probably the comment is very old
[19:03:04] <micges> so what is it done about estop right now is complete?
[19:03:08] <SWPadnos> it seems to me that the message was supposed to reset estop, not generate it
[19:03:12] <alex_joni> right
[19:03:18] <alex_joni> and currently it doesn't
[19:03:31] <alex_joni> taks resets estop by changing status.io.estop
[19:03:42] <micges> but we have estop on and off
[19:04:11] <alex_joni> micges: estop on is F1
[19:04:34] <micges> I know
[19:04:35] <alex_joni> and estop_reset is probably the same as estop_off currently
[19:04:37] <SWPadnos> I'm not sure why iocontrol would need to know if estop is on or not
[19:04:57] <alex_joni> SWPadnos: because the HAL pins for estop are exported by iocontrol
[19:04:59] <SWPadnos> since most actual I/O is done in HAL, using enables or whatnot
[19:05:06] <SWPadnos> oh, well of course there's that :)
[19:05:54] <micges> ok thanks guys
[19:06:30] <alex_joni> * alex_joni heads to bed
[19:06:37] <alex_joni> if a certain someone allows me to
[19:06:44] <SWPadnos> waaaaaaa
[19:06:48] <SWPadnos> night :)
[19:06:57] <alex_joni> indeed
[22:39:39] <cradek> automatic tool throwing arm is working :-)
[22:46:37] <robh> grate, did u get spindle working cradek
[22:50:35] <cradek> it still faults when my A/C starts or stops
[22:51:45] <robh> with that overvolt
[22:52:28] <robh> what make? i know they can be very picky on voltage level in if its not right on money they will error with overvolt or phase error etc
