[00:17:29] <andypugh> I have a 4-pin connector rated 10A on my motor, rated 10A. The max wire size for the connector is 20AWG / 0.5mm2. How does that work then?
[00:17:53] <Tom_itx> same way FET leads works
[00:18:15] <Tom_itx> s/FET/MOSFET
[00:18:43] <andypugh> I think I will be using 1.5mm2 wire and only crimping the cores that fit….
[00:19:12] <Tom_itx> that's where it will get warm then
[00:21:25] <andypugh> It’s for motor power
[00:21:31] <andypugh> to a servo.
[00:21:52] <andypugh> If it’s running 10A for very long then I have the wrong motor
[00:22:53] <andypugh> It’s interesting, I have two very different motors from the same company. A tiny 630W and a huge 1000W.
[00:23:47] <andypugh> (Well, when I say huge, it’s still a 1-hand lift)
[00:27:57] <andypugh> https://picasaweb.google.com/lh/photo/JSYaMjYTNx4jJj6TvWRmrdMTjNZETYmyPJy0liipFm0?feat=directlink
[00:28:14] <andypugh> Little one 630W big one 1000W
[00:28:44] <andypugh> I reckon that most folk with angineering knowledge would assume a bigger ratio
[00:29:16] <Tom_itx> not wanting to load here
[00:30:19] <andypugh> Does it work for anyone else?
[00:31:45] -!- sumpfralle has quit [Ping timeout: 240 seconds]
[00:37:17] <bobo___> workes here. nicely done andypugh
[00:38:57] <andypugh> The big one is twice as large in all dimensions, so ought to be 2500W really. (Assuming that power density scales with the area available to dump heat, rather than volume)
[00:43:50] <trentster> ok a bit more success
[00:44:21] <trentster> I now have the fwd voltage dropping to zero when forward is not clicked and being pulled up to 12.7V when fwd is enabled
[00:44:21] <trentster> the vfd hz increaes when I increase the spindle rpm, yet still no spindle movement, the only time I get a bit of movement is when I click the stop button in the panel and for a second it fires the spindle up
[00:44:21] <trentster> The only led that is illuminated on the vfd display is "Analog"  but "FWD" does not illuminate on the vfd display even when the voltage on fwd pin is pulled high or low.
[00:45:10] <trentster> I am almost there - but man! setting up a VFD for the first time is like 100X harder than getting my 400w spindle working via pwm
[00:45:22] <trentster> Any suggestions for me at this stage?
[00:45:45] -!- Twist [Twist!~twist@heap.pbp.net] has joined #linuxcnc
[00:45:58] <andypugh> It sounds like the “enable” is inverted
[00:46:45] <andypugh> ‘appen as maybe the VFD needs the FWD input connected to GND to start the spindle
[00:47:28] <bobo___> andypugh so what are the Mfg. specifications as to continuous loading of those two servo motors
[00:47:38] <trentster> the control pins on the vfd don't seem to have a dedicated "enable"
[00:47:39] <trentster> https://monosnap.com/file/MqYQ3vrLQjPwcT40DBelnBjLgG0hm9.png
[00:48:20] <andypugh> I was using “enable” generically
[00:48:47] <andypugh> bobo___: I would have to go through the docs.
[00:50:19] <andypugh> It’s not like I chose them on spec, they just came along and look like they will do the job.

[00:57:54] <andypugh> Well, the VFD doc on the right clearly indicates that you connect FWD to GND to start the spindle
[00:58:00] -!- theorbtwo has quit [Remote host closed the connection]
[00:58:41] <andypugh> Did you use Stepconf?
[01:01:02] <andypugh> The breakout board docs there don’t make it especially clear what the output is, or which terminal is which.

[01:05:24] <trentster> let me link to my current config
[01:05:39] <andypugh> Try inverting the sense of the FWD pin
[01:05:56] <andypugh> (it’s a tick-box on the parport config tab)

[01:07:22] <FAalbers> killer-sim: if you're setting up a new ocean sequence or shot - I strongly recommend using OceanParticulate container v2 - the surge and swell prim is much easier to control
[01:07:47] <FAalbers> Oops ! Ignore that ! Wrong channel !
[01:07:52] <trentster> andypugh: yeah I tried inverting the FWD pin already - me thinks
[01:07:54] <andypugh> Wrong channel? But I am fascinated to know what the right channel was
[01:08:01] <trentster> let me try again just to make 100% sure
[01:08:39] <trentster> I do check with voltmeter that when I click fwd the voltage is pulled up from 0 -> 12V
[01:08:55] <trentster> tested this on the vfd side itself
[01:11:10] <FAalbers> andypugh, It's NDA ! :)
[01:11:31] <andypugh> NDA?
[01:11:43] <FAalbers> Non Disclosure Agreement
[01:11:56] <FAalbers> Can't tell ...
[01:11:58] <roycroft> if he tells you he will have to kill you

[01:45:00] <trentster> any other suggestions folks?
[01:46:05] <trentster> Anyone know a person in AU/Melbourne I can pay to come and help me with this - to be quite honest - I am frankly getting to the end of my teather with it!
[01:48:37] <andypugh> Take the wires out of the FWD terminals. Twist them together. What happens then
[01:51:18] <trentster> andypugh: you want me to remove the wires on the vfd side that run from the relay and join them? or you saying vica versa?
[01:51:45] <andypugh> Are they conected to the relay?
[01:52:17] <andypugh> I am speculating from one picture…
[01:52:30] <trentster> yes, andypugh did you see the detailed diagram I linked to you earlier?
[01:53:05] <trentster> this one https://monosnap.com/file/rDt2X3xxdQkKz1ZTVDja29FiHq7rb7
[01:53:15] <andypugh> Yes, I saw that.
[01:53:46] <andypugh> It isn’t terribly detailed about what the magic pixies in the breakout board are doing
[01:54:12] -!- rob_h has quit [Ping timeout: 256 seconds]
[01:54:36] <andypugh> But taking the spindle on/off wires out of the BoB and physically connecting them is pretty unabiguous
[01:55:47] <andypugh> The relay _looks_ to be connected (optionally) to the B-DIR pin,
[01:55:58] -!- asdfasd has quit [Ping timeout: 272 seconds]
[01:56:17] <andypugh> So I have no idea what the spindle on/off putputs do
[01:56:23] <andypugh> (outputs)
[01:56:44] <Jymmm> I liked putputs better
[01:56:58] <trentster> the bob supports pwm to analog 0-10v control.

[01:57:18] -!- Akex_ has quit [Quit: Connection closed for inactivity]
[01:57:29] <trentster> pin 17 on bob is connected to the relay internally as well. Pin 17 in LCNC is configured for Spindle FWD
[01:57:39] <trentster> not much else to it at the moment than that
[01:57:56] <trentster> from a LCNC side, all appears to be working.
[01:57:59] <andypugh> What makes you think that P17 is connected to spindle on?
[01:58:18] <trentster> If I switch on spindle relay is pulled high and FWD pin of VFD is as well
[01:58:35] <andypugh> Disconnect the wires from spindle-fwd.
[01:58:42] <trentster> if I increase rpm the voltage on 0-10V output increases and so does the frequency displayed on the VFD
[01:58:52] <trentster> except spindle no spin
[01:58:55] <andypugh> Put a multimeter across those terminals. What do you see?
[01:59:13] <trentster> The only time it spins is for 2 second when I click the spindle stop button in LCNC UI
[01:59:32] <andypugh> Do you see a “switch” in resistance mode? Do you see a voltage in voltage mode?
[02:00:07] <trentster> andypugh: I have put a multimeter on the FWD wires it is at 12.7V when pulled high and when spindle is switched off its at 0V
[02:00:24] <andypugh> It seems that the 0-10V speed part is working, but the FWD wiring isn’t
[02:00:37] <trentster> how so?
[02:00:37] <andypugh> Realtive to what?
[02:01:15] <trentster> disclaimer: I have very little experience with electronics and schematics, and this is the first external VFD I have setup.
[02:01:18] <andypugh> Just humour me. Disconnect the wires and connect them to each other.
[02:01:36] <trentster> previous spindle was a 400w and had a vfd that was controlled by digital pwm
[02:01:41] <trentster> that worked without issue
[02:01:58] <trentster> ok hang ten I have to run out to the garage
[02:02:03] <andypugh> So the VFD sees a short circuit from GND to FWS
[02:02:07] <andypugh> FWD
[02:02:15] <trentster> yes it does indeed.
[02:02:57] <trentster> When I click FWD in linuxcnc ui I hear the relay click, and on the multimeter connected to the pin on the VFD I See the voltage change from 0 —> 12.7V
[02:03:29] <andypugh> Which voltage. Measured between which points?
[02:04:12] <trentster> However the only led that is illuminated on the VFD is "analog" the "FWD" led does not illuminate, I am not sure if that is only from manual control via vfd panel or if it should illuminate via external as well
[02:05:17] <andypugh> I have only your picture to go by. But there is no evidence that the relay has anything to do with the Spindle On/Off terminals
[02:05:46] <trentster> andypugh: I put the N (black) probe of the multimeter on the GND terminal of the VFD and the L (Red tip) on the FWD pin of the VFD which is pin 8
[02:06:19] <trentster> archivist: uses the same BOB, and this is how he got his to work, albeit he uses a different VFD
[02:06:50] <trentster> this is how I am seeing the voltage being pulled up when I enable spindle FWD in linuxcnc
[02:07:03] <trentster> is that definitive enough or still unclear?
[02:07:28] <andypugh> You don’t want the voltage to change from 0 to 12,7. You want the opposite
[02:07:59] <andypugh> For Spindle FWD you want terminal 8 brought down to GND
[02:08:06] -!- gavlee [gavlee!~gavlee@poker.plus.com] has joined #linuxcnc
[02:08:31] <trentster> oh really hmmmm
[02:08:38] <andypugh> And, as an experiment, you can do that by shorting two wires together. Did that work yet?
[02:08:53] <trentster> ok let me swap the side of the relay then that will accomplish that
[02:09:08] <trentster> well I have not tried yet - been chatting to you ;-)
[02:09:13] <trentster> Garage is outside.
[02:09:19] <trentster> hang ten :-)
[02:09:28] <andypugh> Get on with it, it’s 2am, I want to sleep!

[02:14:44] <roycroft> you greenwegiatempusts are always getting ahead of yourselves
[02:15:01] <roycroft> here on the laid back, mellow west coast of the us we've only gotten around to 6pm
[02:15:52] <andypugh> Interesting map: http://blog.poormansmath.net/how-much-is-time-wrong-around-the-world/
[02:16:18] -!- morbo has quit [Ping timeout: 256 seconds]
[02:16:31] <andypugh> So, yes, the West Coast is largely on the right time
[02:17:10] <andypugh> Whereas most of Europe is very wrong.
[02:17:38] <andypugh> CET should start at the eastern border if France
[02:18:02] <roycroft> except for the majority of the year when we're on summer time
[02:18:14] <roycroft> but that's a whole different conversation
[02:18:31] <andypugh> Isn’t than normally exactly half of the year?
[02:19:09] <roycroft> we've stretched it
[02:19:26] <roycroft> iirc it's from the first sunday in march until the first sunday in november now
[02:19:34] <andypugh> I hate the idea of summer time. If you don’t like when the sun rises, do stuff at different time.
[02:19:53] <trentster> andypugh: nope makes no difference if I join the wires
[02:20:02] <andypugh> Oh
[02:20:16] <trentster> the spindle does not turn regardless of weather the voltage on FWD is 0 or if its 12.7V
[02:20:31] <trentster> that was the purpose of the test right?
[02:20:44] <roycroft> yes, that is correct
[02:20:50] <roycroft> we did the stretching a few years back
[02:21:28] <roycroft> it's the second sunday in march and the first sunday in november
[02:21:37] <andypugh> trentster: Is the VFD configured for FWD / REV + Analog control?
[02:21:43] <roycroft> it used to be the first sunday in april and the last sunday in october
[02:22:30] <roycroft> but we were on year-round summer time during the "energy crisis" of the '70s
[02:22:45] <trentster> andypugh: yes its configured for analog control and I have tried with both both FWD/REV enabled and with only FWD enabled. At the moment its only got FWD enabled in the VFD logic
[02:23:05] <roycroft> i'd rather be on summer time year-round than have to change the clocks around twice/year
[02:23:19] <trentster> you want me to repeat the test with both FWD/REV enabled and not just FWD.?
[02:23:54] <andypugh> trentster: I am afraid I have to go, but I would suggest making sure that the VFD works with a potentiometer and switches (maybe twisted-wire switches) first, then move on to getting the BoB to do the magic

[02:24:20] <trentster> could this issue be that it needs a resistor, the diagram there shows something about a resistor and 12V on GND

[10:17:01] <XXCoder> _abc_: maybe at thingverse?
[10:17:04] <_abc_> I saw a lot of diy folded bellows but no help with the thing used to shape it. It comes out sh*tty by hand.
[10:17:38] <_abc_> XXCoder: Not really, folding bellows and other origami (!) like activities are pleasant the 1st 2-3 times if you're a kid, after that, you want to really get on
[10:17:41] <archivist_> it is just care to get good bents
[10:17:45] <archivist_> bends
[10:17:49] <_abc_> Also this is not going to be paper but some plastic which needs to be scored
[10:18:09] <_abc_> archivist_: exactly. There are about 300 bends in a small bellows like I need, and I am not THAT perfect.
[10:18:15] <_abc_> Also I want to make about 12 of them.

[10:18:50] <archivist_> they get damaged in use too so dont be too fussy either
[10:18:52] <_abc_> I just want it to look good until I break even >;)
[10:19:10] <_abc_> Will use plastic sheet anyway, scored or folded + heated edges or such
[10:19:20] <_abc_> But I am looking for an idea for the initial folding.
[10:19:36] <archivist_> plastic may not be flexible enough
[10:19:48] <_abc_> It is. The ready made machines I use use that.
[10:19:58] <XXCoder> oh yeah! bellows
[10:19:59] <_abc_> But it is not a real bellows just a 'creased sheet'
[10:20:02] <XXCoder> sorry missed that lol
[10:20:12] <archivist_> vinyl or some other flexible
[10:20:16] * _abc_ bellows at XXCoder : BELLOWS
[10:20:24] <XXCoder> lol
[10:20:27] <_abc_> archivist_: it's semi hard vinyl or mylar or such
[10:20:32] <archivist_> he cannot hear you
[10:21:57] <XXCoder> felt him though lol
[10:22:23] <_abc_> http://www.cnczone.com/forums/diy-cnc-router-table-machines/15195-need-template-way-covers-bellows-origami.html nor am I the 1st one to worry about this.
[10:22:52] <XXCoder> did you check out third post 3 links?
[10:23:29] <_abc_> Heh can one use a CNC to score the sheet for said bellows... I think yes. On both sides, one by one...
[10:23:44] <_abc_> What tool would one use? I think a non spinning dull point?
[10:24:01] <_abc_> And something slightly compliant as backing like HDPE plate?
[10:24:02] <XXCoder> what material again?
[10:24:12] <_abc_> Some semi rigid vinyl or such
[10:24:14] <archivist_> I used to collect cameras, that is where I first messed about with them
[10:24:29] <XXCoder> maybe you could make a custom "pointy" tool
[10:24:37] <XXCoder> which can pus dragged around to score
[10:24:39] <_abc_> Yeah the 'bellows' for simple mill lead screws are simple concertina things, not 3d.
[10:25:00] <_abc_> XXCoder: Of course it would be custom. I'll dull the point on one of my scorers...
[10:25:14] <XXCoder> maybe hard rubber as backing
[10:25:24] <_abc_> I have HDPE plates.
[10:25:26] <archivist_> all the flold technically need to be done at the same time which is why a simple tool wont work easily
[10:25:29] <XXCoder> not too sure how firm base need to be
[10:25:40] <_abc_> Neither am I ... thus, asking...

[10:26:07] <XXCoder> but strong enough to indent
[10:26:14] <_abc_> archivist_: I don't know. If I stretch the rectangular sheet on 2 end holders screwed down, I can in theory score it.
[10:26:27] <archivist_> hard rubber and a v in a press to crease
[10:26:36] <_abc_> v in a press?

[10:27:50] <archivist_> http://www.custompartnet.com/calculator/v-bending-force but replace the lower with a complient material

[10:28:17] <archivist_> plane is trivial
[10:28:44] <_abc_> archivist_: It turns out it is not trivial. One needs to pre-score on 2 sides, fold forcibly, and heat set the plastic folded.

[10:29:10] <_abc_> It needs to be mostly under tension or it will bulge out on compression and get in the way. I have nice end mill holes in some to show.
[10:29:50] <archivist_> just fold up then compress
[10:30:09] <_abc_> It doesn't want to stay in shape unless heated and allowed to set while compressed
[10:30:21] <archivist_> heat gun
[10:30:32] <_abc_> The next step is to do a 'U' bellows using the same setup later
[10:30:48] <_abc_> archivist_: indeed. But 1st it needs to be folded down and staying put while you grab the gun etc
[10:31:26] <archivist_> should be simple to clamp between some plates
[10:31:46] <_abc_> Yes... once persuaded to stop trying to get out, which it DOES want to.
[10:32:17] <_abc_> Folding 100 creases in an elastic PVC or Vinyl sheet requires some jig. I want ideas on said jig...
[10:34:10] <_abc_> Ah they call those accordion way covers
[10:34:50] <XXCoder> heated wire at base of hidged jig?
[10:35:03] <XXCoder> bend, hit button to briefly heat wire

[10:35:58] <_abc_> Also, what do seamstresses/tailors use to make plisse skirts ?
[10:36:18] <XXCoder> I hate zoom in and fade.
[10:36:29] <XXCoder> and that guy uses it just few billion times
[10:36:52] <_abc_> watch eedave movies and you'll immediately LOVE the quick slideshow mode this guy uses.
[10:37:14] <XXCoder> honestly its still better than camera on random springs mode.
[10:37:24] <_abc_> Ah he used some coating on it afterwards. I wonder if the Ikea curtains are Tyvek.
[10:37:51] <_abc_> I would not use Nitrocellulose spray paint on anything in a machine shop...
[10:38:01] <_abc_> But Polyurethane is an option...

[10:45:13] <_abc_> Apparently Ikea has a selection of these Plisse style blinds, not just the one in the video. Worth a visit.
[10:51:02] <XXCoder> theres other way I guess
[10:51:08] <XXCoder> roller
[10:51:17] <XXCoder> type that has spring it pull back in
[10:51:23] <_abc_> Roller + shavings / chips / swarf = fail
[10:52:08] <XXCoder> actually not when you arrange it so when it rolls while pulling in, as it turns chips are swept and or fall off
[10:52:15] <XXCoder> but then bit complex :P
[10:54:08] <_abc_> Problem is everyone talks about accordion folding paper which will hold shape and fabric which is sewn and ironed into place. Somehow, everyone shies away from doing that with plastic. No doubt, with very good reason.
[10:54:26] <XXCoder> you can always use sewing machine
[10:54:36] <XXCoder> correctly done it will hold shape
[10:54:46] <XXCoder> but man so much sewing.

[11:18:14] <_abc_> Having a machine which requires bellows large enough to stand in upright with lots of room to spare... I don't want that, but some in this channel might drool at the thought.
[11:20:03] <XXCoder> use those bellows as fancy door, with some cnc stuff
[11:20:12] <XXCoder> click button and it comes up
[11:20:41] <_abc_> Yeah the steel bellows can probably make you jump a block or so if they get loose with you in the way.
[11:22:39] <_abc_> I was once in an exhibition hall at a machinery fair, walked past a vertical turret/turntable mill so large I did not realize what it was until I had walked past it (it was like 10 booths wide)

[11:28:49] <_abc_> Even small mills require special flooring for weight and vibration reasons.

[11:30:03] <XXCoder> theres chinese one thats just $50 but has pulse generator and stfuf
[11:30:33] <_abc_> I know, but have you tried them? I tried those and the kind with one jog wheel and lots of buttons. Both suck.
[11:30:49] <XXCoder> still better than keyboard though
[11:31:19] <_abc_> Disagree. Just make a box with buttons wired to the keyboard's controller. You can use a spare controller/kbd usb type for this.

[11:31:42] <XXCoder> few buttons but theres knob for xyz and encoder wheel which is really all I need.
[11:31:54] <XXCoder> its wireless which cost a little bit more
[11:31:58] <_abc_> Have you tried it out? I have tried such a thing, did not like it.
[11:32:09] <XXCoder> what was wrong?
[11:32:42] <_abc_> I would not be surprized if there's be a phone app to do it now. Tilt phone to control xy, lower and raise to traverse Z, rotate to turn vertical axis table...
[11:33:11] <_abc_> XXCoder: awkward operation, unsuitable stepping for the jog wheel, you still have to push buttons a lot.
[11:33:28] <XXCoder> heh crash by dropping phone...
[11:33:42] <XXCoder> I had one, I certainly dont wanna see another crash.
[11:33:51] <_abc_> There already is a quite fancy phone based DRO. See TouchDRO on youtube. Free too.
[11:34:03] <_abc_> You had ONE crash? Rookie!
[11:34:30] * _abc_ frequently operates Chinese mills with no end stops and or end stops only on one end.
[11:35:04] <_abc_> XXCoder: you need a jog pendant like this http://www.k-mm.com/wp-content/uploads/2014/12/large_machining_121_control_picture5.jpg ...
[11:35:36] <XXCoder> it was... "fun" crash. chuck crashed into fixture, pushed it into next kurt jaw

[11:35:54] <_abc_> Okay that is not good.
[11:36:00] <XXCoder> yeah
[11:36:01] <_abc_> Programming error?
[11:36:16] <XXCoder> no, okuma does not change tools when tis first tool
[11:36:25] <XXCoder> and I forgot to change tools to first one for program
[11:36:26] <_abc_> hm?
[11:36:38] <_abc_> Oh. Ouch.
[11:36:40] <XXCoder> okuma suck on that
[11:36:59] <_abc_> I don't know Okuma at all but I'll remember that.
[11:37:13] <XXCoder> depends on year I bet
[11:37:17] <XXCoder> its somewhat old model
[11:37:24] <_abc_> More likely on sw version?
[11:37:32] <XXCoder> though its AWESOME on one way, it moves spindle for Z and Y
[11:37:36] <XXCoder> table only does X
[11:37:43] <XXCoder> means its always easy to reach parts
[11:37:47] <_abc_> Gantry?
[11:38:03] <_abc_> oh okay
[11:38:04] <XXCoder> no, it just moves down up and forward and back
[11:38:13] <XXCoder> strange design
[11:38:23] <_abc_> Well many manual older mills are exactly like that
[11:38:27] <XXCoder> but always easy to access table which is good if you has very heavy stock
[11:38:44] <XXCoder> not that okuma at work does many heavy poarts lol quite old

[15:15:13] <Tom_itx> well get the lead out!
[15:15:14] <zeeshan|2> and im getting overflow.. and i think its because i didnt make it a 2 part mold
[15:15:28] <archivist_> I certainly got rounded edges as it was open top
[15:15:35] <zeeshan|2> ah
[15:15:37] <zeeshan|2> im getting the same issue
[15:15:41] <zeeshan|2> and its not filling the entire mold
[15:15:45] <zeeshan|2> its cooling way too fast.
[15:15:53] <zeeshan|2> i think i need to preheat the mold to more than 100c

[15:17:33] <zeeshan|2> wouldnt that cause it to act like a riser also
[15:17:39] <zeeshan|2> i was thinking of using the sprue as the riser
[15:17:47] <archivist_> yes you watch that to know its full
[15:18:00] <zeeshan|2> why cant i just overflow the sprue
[15:18:15] <archivist_> it finds its level :)
[15:18:28] <zeeshan|2> also has anyone here used MD-7 trico corp coolant?
[15:18:32] <archivist_> keep filling as it cools
[15:18:36] <zeeshan|2> these idiots do not have mix instructions online
[15:18:42] <zeeshan|2> so i thought maybe i need to run it pure
[15:18:50] <zeeshan|2> but in my experience, it seems VERY wrong to run it pure because of it's viscoity
[15:18:58] <zeeshan|2> there is no instructions on their website or the jug on how to mix it

[15:19:14] <zeeshan|2> i was so frustrated yesterday night
[15:19:25] <zeeshan|2> okay ill make another plate
[15:19:34] <zeeshan|2> do you think i need to have a clamp mechanism or something to hold the 2 parts together
[15:19:38] <archivist_> get that mould pretty hot for decent cooling
[15:19:39] <zeeshan|2> its a small part
[15:19:51] <zeeshan|2> im wondering if it will lift the secondary mold
[15:19:56] <zeeshan|2> and cause flashing
[15:20:20] <archivist_> yes it will float off if you dont do something
[15:21:01] <zeeshan|2> i could put 2 pins on each mold, on 2 of the sides
[15:21:13] <zeeshan|2> and use some sort of cam action lock?
[15:21:22] <zeeshan|2> simplest thing i can think of on the top of my head
[15:21:26] <zeeshan|2> i dont wanna bolt the 2 plates together
[15:21:28] <archivist_> plaster board is dead cheap for that job
[15:21:28] <zeeshan|2> cause it gets hot :P
[15:21:43] <zeeshan|2> archivist we're making around 40
[15:21:46] <zeeshan|2> thats why we went with steel
[15:22:07] <zeeshan|2> its christmas present/ornament for coworkers
[15:22:30] <DaViruz> zeeshan|2: i don't think that stuff is supposed to be diluted
[15:22:31] <archivist_> I used plaster board to make a rectangular weight for a clock
[15:22:49] <zeeshan|2> daviruz you thinkso?
[15:22:49] <DaViruz> their other products have mixing instructions, and the specifications says they are water soluable
[15:22:54] <zeeshan|2> its wayooo to think
[15:22:58] <zeeshan|2> it is definitely water insoluable
[15:23:04] <zeeshan|2> it says that online
[15:23:17] <zeeshan|2> but i think youre supposed to mix it with make it an water-oil emulsified mixture
[15:23:24] <zeeshan|2> because the water provides the cooling
[15:23:26] -!- patrickarlt has quit [Client Quit]
[15:23:27] <zeeshan|2> the oil doesnt do much for cooling
[15:23:47] <zeeshan|2> 96% of the product is mixed parrafin based
[15:23:57] <archivist_> oil is an insulator and a killer in cooling circuits
[15:24:04] <zeeshan|2> yes archivist_herron
[15:24:10] <DaViruz> well they don't market it as a coolant, they market it in a lubricant
[15:24:18] <DaViruz> to be used with micro dispensing
[15:25:07] <DaViruz> "Compared to flood cooling, there is no coolant sump to maintain or used coolant to dispose of."
[15:25:20] <zeeshan|2> that doesnt mean anything though
[15:25:25] <zeeshan|2> thats comparing mql with flood
[15:25:31] <zeeshan|2> mql is supposed to evaporate
[15:25:42] <zeeshan|2> but there is oil emulsified coolants used in mql mostly
[15:25:55] <zeeshan|2> but youre right i have read literature where there is oil only also
[15:26:04] <zeeshan|2> but thats meant for like tapping and those type of slow ops

[22:09:44] <CaptHindsight> you could probably get a crate full of them in better shape for cheap but the shipping will be pricey
[22:09:59] <t12> i like the i found this washed up on the beach part
[22:10:54] <CaptHindsight> I just noticed that it's used and was under water
[22:11:10] <pcw_home> how do they know its a gyroscope?
[22:11:24] <t12> dunno
[22:12:19] <CaptHindsight> http://nuclearweaponarchive.org/Usa/Weapons/Airs1.jpg
[22:12:38] <pcw_home> looks more like a pressure vessel/accumulator
[22:13:18] <t12> hard to tell from the photos
[22:13:37] <t12> i think that owuld be dictated by if thats an electrical conduit at the bottom
[22:13:49] <t12> looks like a vacuum/gas fill port on the side of the big connector assembly
[22:13:57] <t12> would be very annoying to get into without destroying looks like
[22:15:02] <pcw_home> I dont see any reason for a gyroscope to be in a welded container
[22:15:15] <CaptHindsight> I think it directly translates as "Acme Missile Gyros"

[22:16:45] <t12> where theres two gears that appear to be coupled
[22:16:47] <t12> anti-backlash thing?
[22:16:52] <CaptHindsight> "might be the gyroscope or the fissionable material"
[22:17:27] <pcw_home> I guess it could be running in a vacuum
[22:17:59] <pcw_home> probably not something I need
[22:18:16] <CaptHindsight> maybe the plug on the side unscrews
[22:19:21] <t12> i finally i succeeded at gutting that astrotracker
[22:19:22] <t12> https://www.instagram.com/p/_LmUWwACgR/
[22:19:31] <t12> pretty intense device
[22:22:31] <CaptHindsight> http://theodoregray.com/periodictable/Samples/004.11/index.s12.html
[22:23:33] <CaptHindsight> http://theodoregray.com/periodictable/Samples/004.14/index.s12.html so they used to put them in spheres
[22:24:34] <CaptHindsight> http://theodoregray.com/periodictable/Samples/004.24/index.s12.html
[22:25:15] <pcw_home> is the astrotracker 2 axis (alt/azimuth)?
[22:25:32] <t12> yeah
[22:25:34] <t12> i think
[22:25:59] <t12> the lens rotates and pivots
[22:26:07] <t12> then the whole thing is motorized on two axis
[22:26:30] <t12> all controls seems to be synchro + servo feedback?
[22:26:31] <pcw_home> I had one from a ICBM a long time ago, it had direct drive brushed torque motors
[22:26:52] <t12> i dont quite understand the drive mechanisms theres at least 3 motor/synchro/resolvers
[22:26:58] <t12> per axis
[22:27:40] <pcw_home> maybe servo + fine/coarse syncros
[22:27:54] <t12> gradually i'll take good detail pics
[22:28:05] <t12> i dunno what the next step in high complexity mechanical machines would be
[22:28:15] <t12> maybe a mechanical fire control computer
[22:28:24] <t12> - the redundant mechanical/machines
[22:29:21] <JT-Shop-> can you use 24v with a probe like this to a 7i77? http://deepgroove1.com/stainlessprobe/stainlessprobe.htm
[22:30:28] <pcw_home> It _might_ wear the contacts faster (about 1 mA at 24V)
[22:31:23] <JT-Shop-> I guess I could use a parallel port input if I had one
[22:31:29] <pcw_home> I dont know enough about contact wear vs voltage to know for sure
[22:32:13] <JT-Shop-> I probably would not use it very much...
[22:32:22] <pcw_home> Yeah parallel port, free encoder input pin, 7I77 input and transistor or OPTO
[22:32:29] <JT-Shop-> but from time to time it would be handy
[22:33:45] <pcw_home> probably ok then (needs a 2 wire probe not 1 wire and ground)
[22:38:16] <JT-Shop-> I'm guessing he put that for the parallel port as an input
[22:40:24] <JT-Shop-> I'm thinking if there is no circuit in it then it is just a switch
[22:42:57] <CaptHindsight> JT-Shop-: do you use them to reverse engineer or align the machine?
[22:44:03] <JT-Shop-> both
[22:44:23] <Tom_itx> likely just 3 switches
[22:44:29] <JT-Shop-> like I have a part to duplicate and it would be nice to probe the taper at two levels and get the angle
[22:44:44] <JT-Shop-> like the basic renishaw probe
[22:44:50] <pcw_home> Yeah its a parallel port input with a pullup so normally low and high when tripped
[22:50:23] -!- gavlee has quit [Quit: How now Larry the cow?]
[22:52:03] <gregcnc> No luck figuring out what that taper was?
[22:52:41] <JT-Shop-> I'm pretty sure I know what it is but a probe would have been much easier
[22:53:09] <JT-Shop-> I need to check the hardness so while I'm at my buddies shop we can put it on the dmm
[22:54:23] <JT-Shop-> dang, I scared the deer away checking the battery on the crawler

[23:09:24] <Roguish> JT-Shop: are you considering a probe like you just posted?
[23:09:49] <JT-Shop-> well yes it has progressed past considering
[23:09:58] <Tom_itx> oops
[23:10:23] <JT-Shop-> we shall see
[23:10:30] <JT-Shop-> when it arrives
[23:10:58] <Roguish> I have been looking quite seriously. thought about making one, but time vs. cost it's not easy.
[23:11:12] <Roguish> who actually makes ti?
[23:11:14] <Roguish> it?
[23:11:50] <Tom_itx> if you decide to make one i'd sure consider gold plating the contacts
[23:12:22] <JT-Shop-> I don't know who makes it but like you time vs cost is the factor at this point
[23:12:46] <JT-Shop-> I've dropped the hammer on that one to see if it is as good as my BP
[23:13:14] <Roguish> i have some gold plated 'dumbbell' body piercing ornaments picked out at Amazon.
[23:13:33] <Tom_itx> good idea
[23:13:41] <Roguish> BP ==? bridgeport?
[23:14:31] <JT-Shop-> yea, series 1 with Anilam 3 axis CNC conversion
[23:14:39] <Roguish> only advantage to making one is that I would make a few extra parts for the occasional oops.
[23:14:59] <Roguish> sometimes I get the dropsies.
[23:15:25] <JT-Shop-> I have the 3-D cad for one just don't have time right now, trying to finish the shop and other things
[23:15:31] <Tom_itx> http://www.carbideprobes.com/
[23:15:36] <Tom_itx> you can get stylus there
[23:17:10] <JT-Shop-> maybe make the optical comparator into a dmm lol
[23:19:59] <JT-Shop-> I did manage to ride my new to me road bike yesterday, made some adjustments ready to ride
[23:20:38] <Tom_itx> why you switchin from trail to road now?
[23:21:19] <Roguish> good. I got in a quick 20 miler today. supposed to pour rain tomorrow. new tires last week. was into the 'milage plus' on the rear. (a spot of cords showing....)
[23:21:22] <JT-Shop-> not switching, just when the trail is messed up from rain or freeze thaw I can still ride
[23:22:29] <JT-Shop-> I'm jealous of my sister, they have hundreds of paved trails to ride and one that goes all the way to Alabama
[23:23:03] <JT-Shop-> yea rain here too tomorrow
[23:23:08] JT-Shop- is now known as JT-Shop
[23:23:11] <Tom_itx> same here supposedly
[23:23:17] <Tom_itx> been cloudy all day but dry
[23:23:29] <JT-Shop> hope to get the over the garage door shelves done
[23:23:57] <JT-Shop> that will give me 32 sq ft of storage
[23:24:19] <zeeshan|2> ITS MACHINING TIME MY FRIENDS!!
[23:24:30] <JT-Shop> YIPPIE!
[23:24:49] <zeeshan|2> its so nice to have a friend here whos int othe same stuff
[23:24:50] * JT-Shop is about to put on the chef hat
[23:24:53] <zeeshan|2> hes running the warm up program
[23:24:57] <zeeshan|2> and im upstairs doing some cam
[23:25:06] <Roguish> I made up a simple anvil for my Wilson hardness tester the other day.
[23:25:10] <JT-Shop> no one around here knows what I do lol
[23:25:23] <zeeshan|2> jt shop its hard find friends who are into same hobbies
[23:25:25] <rob_h> not even you !!
[23:25:28] <zeeshan|2> i see some people are strictly into machining
[23:25:35] <zeeshan|2> some are into going out
[23:25:41] <zeeshan|2> some are into hiking, but its to find a mix.
[23:26:01] <JT-Shop> yea rob_h sometimes I'm lost
[23:26:37] <Roguish> machining is fun, but ya gotta stay healthy. biking is sooo mush better/easier than running. and ya get to see more country side.
[23:26:46] <zeeshan|2> :)
[23:26:50] <JT-Shop> my neighbor is into Mtn bike an road bikes
[23:26:51] <zeeshan|2> i love hiking and astronomy
[23:27:11] <JT-Shop> so we ride together when we can
[23:27:16] <Tom_itx> you stare at the stars while riding??
[23:27:17] <Roguish> hike like you mean it.
[23:27:19] <zeeshan|2> JT-Shop: we ride together we die together !!!
[23:27:27] <zeeshan|2> fast and the furious.
[23:27:44] <JT-Shop> sometimes it's like that on the trail lol
[23:27:47] <Tom_itx> watching that atm..

[23:28:17] <JT-Shop> he's just a youngster at 60 so I try to make him catch the old man lol
[23:28:49] <JT-Shop> the butthole is the boss as I understand
[23:28:52] <Roguish> I get to be 60 in 12 days. better than the option, I think.
[23:29:04] <Roguish> at least for a while..
[23:29:14] <Tom_itx> zeeshan|2 get your casting done?
[23:29:25] <JT-Shop> yea, I used to think 60 was old till I passed it up
[23:29:36] <Tom_itx> makes me feel good...
[23:30:09] <Tom_itx> and here i thought i was old
[23:30:28] <JT-Shop> I'm 15 lbs from being at my target weight so I'm pretty stoked
[23:30:50] <JT-Shop> just glad to be in control of my gravitational attraction again
[23:30:59] <Tom_itx> i was too until i tore into this pizza.. now i'm not gonna check
[23:31:28] <JT-Shop> yea, I still tear pizza up but not often
[23:31:42] <Tom_itx> same here
[23:31:52] <JT-Shop> wife is even losing eating like me
[23:32:18] <Tom_itx> but she's in Ga so i figured i'd treat myself and kid

[23:35:30] <JT-Shop> give me some steak tartar or carpaccio
[23:36:01] <Tom_itx> not bad for flavored cardboard
[23:36:09] <Roguish> that probe kinda looks like this one: http://www.cadcamcadcam.com/probe-tp100probe.aspx
[23:36:10] <JT-Shop> lol
[23:36:39] <JT-Shop> it does
[23:36:49] <Roguish> steak tartar with ice cold vodka. out of this world
[23:37:32] <JT-Shop> I'm a good cognac on a cold night guy
[23:38:11] <JT-Shop> remy martin is a favorite
[23:38:20] <Roguish> just don'
[23:38:25] <_methods> no courvosier?
[23:38:32] <Roguish> just don't add coka a cola to it.....
[23:38:45] <JT-Shop> to cognac?
[23:38:58] <_methods> coke and cognac lol
[23:38:59] <JT-Shop> courvosier is ok
[23:39:06] <Tom_itx> Roguish this was simple to make: http://tom-itx.no-ip.biz:81/~webpage/emc/probe_index.php
[23:39:16] <Roguish> haven't you ever heard of remi and coke? it's stickly ghetto.
[23:39:31] <Tom_itx> but i lacked a good way to index the holes for the probe part so it's a tad bit off
[23:39:43] <Roguish> Tom_itx: thanks. bookmarked it.
[23:39:45] <JT-Shop> no, never tried to add anything to remy
[23:39:59] <JT-Shop> Tom_itx: nice
[23:40:04] <Tom_itx> i made 2 or 3 a couple different sizes
[23:40:10] <Tom_itx> i wanted a small one for the sherline
[23:40:40] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/emc/probe_holder.jpg
[23:40:47] <Tom_itx> those holes are off a tiny bit
[23:40:53] <JT-Shop> time to cook some pad thai
[23:41:02] <JT-Shop> goodnight
[23:41:04] <Tom_itx> if i had an indexer i could have done better
[23:41:06] <Tom_itx> later JT-Shop
[23:41:12] <Roguish> most designs like that have radial set screws to adjust the runout.
[23:41:21] <Tom_itx> gonna fire up catia here soon
