[00:44:57] <Lcvette> whats crackin
[00:45:23] <hazzy-m> not much
[00:45:31] <hazzy-m> been relaxing a bit
[00:45:45] <Lcvette> same, just watched a movie with the wife
[00:45:57] <Lcvette> the spy who dumped me
[00:46:00] <Lcvette> pretty funny
[00:46:43] <hazzy-m> I just watched an episode of Three's Company
[00:46:43] <hazzy-m> LOL
[00:47:29] <Lcvette> hahaha
[00:47:35] <Lcvette> old school
[00:47:42] <Lcvette> come and knock on my door
[00:51:12] <Lcvette> is the G0602 your only lathe?
[00:57:12] <hazzy-m> I have an HF 7x10 mini lathe as well, but I don't use it any more
[00:57:16] <hazzy-m> thinking about selling it
[01:02:40] <Lcvette> hahaha, me too
[01:02:45] <Lcvette> i use it all the time
[01:02:50] <Lcvette> used it today
[01:04:00] <hazzy-m> I used it on Thanksgiving for the heck of it, but the G0602 is so much more convenient
[01:04:02] <hazzy-m> even for small stuff
[01:04:12] <Lcvette> yeaH I BET
[01:04:21] <hazzy-m> But I did a LOT on the little lathe
[01:04:35] <hazzy-m> I did more with it than I have done so far on the G0602
[01:05:34] <Lcvette> I need to turn a big part for the rhino build and i am not thinking the HF7x10 is gonna handle it
[01:05:56] <Lcvette> bit long
[01:06:00] * hazzy-m uploaded an image: image.png (1706KB) < https://matrix.org >
[01:06:04] <hazzy-m> do you have another lathe?
[01:06:20] <hazzy-m> I could maybe knock it out for you ...
[01:06:47] <Lcvette> may take you up on it if i can't manage it on the HF
[01:07:33] <Lcvette> its a spacer for between the front and rear headstock plates
[01:08:04] <hazzy-m> how accurate does it need to be?
[01:08:35] <hazzy-m> could be an excuse to get my friends cylindrical grinder fired up ...
[01:08:43] <Lcvette> the only accurate part is the length
[01:08:55] <hazzy-m> ok
[01:08:57] <Lcvette> and face parrelelism
[01:09:19] <hazzy-m> what is the diameter?
[01:09:42] <Lcvette> since not sure just yet but between 3.5" and 3.75"
[01:10:03] <Lcvette> maybe 4"
[01:10:13] <hazzy-m> ok, you could do that an the 7x10 but it would take a while
[01:10:15] <Lcvette> its a hollow tube
[01:10:32] <Lcvette> its 8" long
[01:10:36] <Lcvette> lllol
[01:11:04] <Lcvette> and i would be chucking it on the inside
[01:11:25] <hazzy-m> oh, I see
[01:11:33] <hazzy-m> that might not be fun
[01:11:51] <Lcvette> not sure i could keep it stable enough to get the faces accurate and parallel
[01:16:09] * Lcvette uploaded an image: scv_1543717400786766008881.jpg (311KB) < https://matrix.org >
[01:17:37] <Lcvette> this is the headstock
[01:17:52] <Lcvette> they used deep groove roller bearings
[01:18:18] <Lcvette> im swapping out to Nachi Tapered Roller Bearings for more regidity and better runout
[01:18:44] <Lcvette> but the preload needs some better rigidity between the bearing mounting plates
[01:20:17] <hazzy-m> interesting, not castings
[01:20:25] <Lcvette> no weldment
[01:20:36] <Lcvette> bad weldmentneeds alot of fixin
[01:20:44] <Lcvette> not flat
[01:20:46] <Lcvette> AT ALL
[01:20:49] <hazzy-m> could build that in a few hours with a water jet
[01:21:05] <Lcvette> it would appear they tried
[01:21:14] <hazzy-m> haha
[01:21:44] <Lcvette> bed has about 0.009" of twist and bow in all sorts of directions
[01:22:00] <Lcvette> im having to cut the frame off and make a new one and machine it
[01:22:10] <Lcvette> i don't think they machined this one before plug welding it
[01:22:49] <hazzy-m> reminds me of my CNC tubing notcher: https://www.youtube.com
[01:22:54] <hazzy-m> oh, that is not good
[01:23:16] * Lcvette uploaded an image: scv_1543965816493751152499.jpg (513KB) < https://matrix.org >
[01:23:31] <Lcvette> yeah, the build leaves alot to be desired
[01:23:35] <Lcvette> it was a training lathe
[01:23:41] <Lcvette> not a make something real lathe
[01:24:39] <hazzy-m> it looks reasonably well thought out though, should be quite capable once you get it sorted
[01:25:09] <Lcvette> oh it will be a beast when im done with it
[01:25:35] <Lcvette> im switching out to an I-Beam frame design filled with Castinite
[01:25:46] <hazzy-m> nice!!
[01:25:50] <Lcvette> 4" I Beams
[01:25:57] <Lcvette> 3/8" wall
[01:26:16] <hazzy-m> with the castinite that will be very stout
[01:26:19] <Lcvette> and redesigned the x and z
[01:26:34] <hazzy-m> so your building a new lathe?
[01:26:35] <hazzy-m> lol
[01:26:53] * Lcvette uploaded an image: ST8 Lathe Rendering.JPG (454KB) < https://matrix.org >
[01:27:24] <hazzy-m> sweet!
[01:27:33] <Lcvette> kinda
[01:27:45] <Lcvette> reusing alot of things
[01:27:53] <Lcvette> but replacing alot too
[01:28:10] <Lcvette> some things they did really well
[01:28:20] <Lcvette> wome thingsd they failed miserably at
[01:28:28] <Lcvette> spindle they knocked out of the part
[01:28:37] <Lcvette> turret is stout
[01:28:43] <Lcvette> drive is clunky
[01:28:46] <Lcvette> but its stout
[01:28:58] <Lcvette> servo will cure that though
[01:29:35] <Lcvette> so a gorgeous D1-4 5" camlock spindle with 1.5" bore
[01:29:43] <Lcvette> but then used shit bearings
[01:29:47] <Lcvette> lol
[01:30:15] <Lcvette> they used thompson round rod linear stages for the axis
[01:30:25] <Lcvette> with ground ballscrews
[01:30:31] <Lcvette> lol
[01:31:11] <Lcvette> but then for the end bearings they used a double row single ac bearing for more radial loading then thrust
[01:37:46] <hazzy-m> round linear bearings? strange choice
[01:38:10] <hazzy-m> does not sound like they were cheap, but odd choices
[01:38:24] <Lcvette> yeah they did some things to make production simple like use the preassembled linear stages
[01:38:44] <hazzy-m> ah, that makes sense
[01:39:01] <hazzy-m> well, I think I better hit the hay here
[01:39:08] <hazzy-m> night!
[01:39:20] <Lcvette> same here! night man
[08:41:46] -!- jthornton has joined #hazzy
[08:42:28] <Lcvette> motning
[08:42:31] <Lcvette> morning
[08:43:34] <jthornton> morning
[08:51:27] <jthornton> hazzy-m: any clue how I can run GPIO.cleanup() on exit from my pyqt4 chicken control? https://paste.ubuntu.com
[09:29:48] <hazzy-m> Qapplicatuon as an about to exit signal
[09:48:08] <jthornton> thanks, I'll look that up... I did find out that ctrl c does not exit the app because qt is running in c
[10:08:36] <hazzy-m> on PyQT5 it would be `QApplication.instance().aboutToQuit.connect(self.do_shutdown)`
[10:08:57] <hazzy-m> and then do the GPIO cleanup in the do_shutdown method
[10:10:11] <hazzy-m> you can exit a QT app with `ctrl + \`
[10:12:45] -!- JT-Shop has quit [Remote host closed the connection]
[10:14:00] -!- JT-Shop has joined #hazzy
[10:17:01] <hazzy-m> jthornton: sorry, was on moble and did't see your paste
[10:17:02] <hazzy-m> all you need is `app.aboutToQuit.connect(GPIO.cleanup)`
[10:17:35] <hazzy-m> put it after you you define the app, but before you run it
[10:23:01] <JT-Shop> ok thanks
[13:52:43] <Lcvette> whats cracking?
[15:09:10] <jthornton> hazzy-m: finally got it to work and this is the condensed code https://paste.ubuntu.com
[15:10:13] <jthornton> the full code if your curious https://paste.ubuntu.com
[15:27:42] <JT-Shop> Lcvette: eggs lol
[16:01:56] <hazzy-m> on close event should work most of the time, but what if the app is by some other means than closing he window, does the close event fire?
[16:18:54] <Lcvette> JT
[16:19:15] <Lcvette> You're not wrong
[16:19:18] <Lcvette> Lol
[16:19:33] <Lcvette> Wife and I decided on breakfast for dinner
[16:19:40] <hazzy-m> LOL
[16:19:57] * Lcvette uploaded an image: VectorImage_2018-12-07_041947.jpg (66KB) < https://matrix.org >
[16:20:28] <hazzy-m> 👍
[16:51:46] <JT-Shop> it won't fire if you do ctrl / but the X and the exit button work
[16:53:22] <hazzy-m> did you try: app.aboutToQuit.connect(GPIO.cleanup) ?
[16:53:38] <hazzy-m> that should always fire
[17:24:35] <jthornton> I tried that but could not get it to work, I must have done something wrong
[17:24:36] <Lcvette> I talked to jeff
[17:25:15] <hazzy-m> it might not work in PyQt4
[17:25:19] <jthornton> GPIO.cleanup() is a GPIO method not something I wrote
[17:25:24] <hazzy-m> how is he?
[17:25:32] <hazzy-m> right
[17:26:35] <jthornton> https://stackoverflow.com
[17:26:50] <jthornton> that page suggests that it works with pyqt4
[17:27:15] <jthornton> I'll try again in a bit
[17:27:42] <hazzy-m> that indicates that is whould work
[17:27:44] <hazzy-m> hmm
[17:27:59] <Lcvette> He's been working in the shop
[17:28:12] <hazzy-m> should + would = whould
[17:28:14] <hazzy-m> LOL
[17:28:59] <Lcvette> Be doesn't have a laptop so for Linux right now but will set one up to work on the gui this weekend
[17:29:19] <Lcvette> Told about the progress and how awesome it is coming together
[17:29:19] <hazzy-m> Hurray!!
[17:29:48] <Lcvette> Hurray
[17:30:15] <Lcvette> Think we'll have a Christmas miracle?
[17:42:39] <Lcvette> Hazzy, for the atc manual function buttons, those are mostly just snail strings of mdi code, is that something easy to setup that I can d do and work on?
[17:42:56] <Lcvette> Small not snail
[17:42:58] <Lcvette> Lol
[17:44:30] <jthornton> alright the chickens are on the roost time to blow up some programs
[17:44:45] <Lcvette> Booooooom
[17:45:44] <hazzy-m> yes. those should be easy if all it is is MDI commands
[17:46:33] <Lcvette> I think that's all it is as that's how it's moved in gmoccapy currently
[19:03:01] <Lcvette> Hazzy, do I just copy the zero button format?
[19:03:30] <hazzy-m> yes
[19:03:57] <Lcvette> K
[19:04:52] <jthornton> hazzy-m: altendky gave me the clue I needed to get this to work https://paste.ubuntu.com
[19:06:17] <jthornton> works the same as the other way and ctrl \ just does a Quit (core dumped)
