[00:00:12] <toastyde1th> though i am sure it's indespensible in some cases
[00:01:43] <JT-Shop> if you have nothing but a laser level and the need to see if something is flat or not it should work yes?
[00:02:04] <toastyde1th> oh, for sure.
[00:02:18] <toastyde1th> in the general sense
[00:02:33] <toastyde1th> I can't think of a situation where that's the metric, though
[00:02:47] <tjb1> JT-Shop: Honey, dinner is ready
[00:02:51] <JT-Shop> lol
[00:03:06] <toastyde1th> cutting rails, etc
[00:03:18] <toastyde1th> you know the general cross-sectional error
[00:03:23] <toastyde1th> but not enough to actually fix anything
[00:03:34] <tjb1> JT-Shop: I ordered THCAD today.

[00:17:16] <Tom_itx> laser levels are used in ship building
[00:17:44] <Tom_itx> assuredly a bit more accurate than the one above
[00:19:06] <tjb1> so as long as I give it the correct pins in HAL, I can just loadrt thc and be done?
[00:19:14] <JT-Shop> anyone want to help me wrestle the plasma water table back into place
[00:19:23] <JT-Shop> aye
[00:19:48] <toastyde1th> i will
[00:19:57] <toastyde1th> I was planning on going to the gym then I started drinking
[00:20:00] <toastyde1th> so i guess that's not happening
[00:20:08] <toastyde1th> might as well wrestle with a water table instead of deadlifts
[00:20:08] <tjb1> Is it setup to use the emcmot encoder?
[00:21:22] -!- Valen [Valen!~Valen@c122-108-45-139.blktn6.nsw.optusnet.com.au] has joined #linuxcnc
[00:21:57] <tjb1> http://www.linuxcnc.org/media/kunena/attachments/legacy/files/thc.comp
[00:22:42] <JT-Shop> ?
[00:23:07] <JT-Shop> http://linuxcnc.org/docs/devel/html/man/man9/thc.9.html
[00:24:04] <PCW> you will have to add the encoder comp and wire its velocity out to the thc comp
[00:25:40] <tjb1> Reading
[00:25:45] <tjb1> :)
[00:25:52] <PCW> the man page is a bit more specific than it needs to be (any encoder velocity signal should work)
[00:26:38] <PCW> you will also need to jumper the THCAD so it generates a frequency that the software encoder counter can read
[00:27:07] -!- Patang [Patang!~freenode@cm-] has joined #linuxcnc
[00:27:29] hdokes is now known as hdokes|werkin
[00:27:42] <tjb1> Which part determines where the jumper is set?
[00:27:47] <tjb1> The frequency the BOB can transmit?
[00:28:23] <PCW> probably your base thread frequency
[00:29:19] <JT-Shop> this? HAL Plasma Connections hm2_5i20.0.encoder.00.velocity => thc.encoder-vel
[00:29:28] <PCW> which determines how fast the inputs can be sampled
[00:30:17] <PCW> Yes. You may also need a low-pass filter to get enough resolution with the software encoder
[00:30:57] <PCW> encoder.velocity --> lowpass--> THC input
[00:30:59] <tjb1> So that would end up being something like parport.1.encoder.00.velocity => thc.encoder-vel
[00:31:04] <Valen> pcw or any other clever person, somebody was on here recently having issues with a rotary axis doing exact stop moves only not G64 P style, was that resolved?
[00:31:16] -!- mhaberler has quit [Quit: mhaberler]
[00:31:19] <tjb1> Valen, wasnt that Aero-Tec
[00:31:23] <Valen> yeah
[00:31:37] <Valen> I'm going to get a rotary soon so i'm somewhat interested too
[00:31:51] <PCW> Not that I know of, Andy had a nice video demo of the bug
[00:32:55] <Valen> I suggested a workaround for his paticular issue by using the rotary axis as a linear but its much less than ideal
[00:33:33] <PCW> JT-Shop, yes it should work with any encoder input tha has decent velocity estimation though you may need a low-pass filter
[00:34:11] <tjb1> PCW - parport.1.encoder.00.velocity => thc.encoder-vel?
[00:34:26] <tjb1> Well thats using parport 1 and it doesnt have an encoder pin so scratch that.
[00:34:36] <Valen> andypugh: you are playing with rotating ballnuts hrm?
[00:34:39] <PCW> Yes but like I said you will likely need a lowpass in there
[00:35:13] <Valen> My local hywin rep said the pre-made ones only come where the lead matches the diameter of the screw, IE the 25mm nut has a 25mm lead which is less than ideal
[00:35:35] <tjb1> PCW: software filter?
[00:35:39] <tjb1> http://linuxcnc.org/docs/html/man/man9/lowpass.9.html
[00:35:51] <andypugh> I am, and my machine already has one fitted and working.
[00:35:58] <PCW> Yep
[00:36:00] <JT-Shop> PCW: I'll make the wording less specific in the morning
[00:36:02] <Valen> home made or off the shelf?
[00:36:27] <andypugh> As I see it they are 100% equivalent and you should choose which way you go on the basis of other factors.
[00:36:43] <JT-Shop> at the time it was monkey see monkey do...
[00:37:02] <Valen> I figured the lube arrangement may well be different as could the returns given all that spinning
[00:39:41] <andypugh> This is option 1 (trailer wheel bearing) https://picasaweb.google.com/lh/photo/EqgIdXH-kCH8I90oYKfm2dMTjNZETYmyPJy0liipFm0?feat=directlink
[00:40:02] <andypugh> Inventor crashed part way through option 2
[00:40:58] <andypugh> (Not as complex as it might look, one casting, 2 turned parts)
[00:41:19] <andypugh> Green is the ballscrew
[00:41:35] <andypugh> Time to find out what is left of option 2
[00:41:38] <Valen> I'd probably just mill out the "casting"
[00:42:03] <Valen> the reason I'm interested is we are doing a half sheet mill/router and want some decent speeds
[00:42:10] <andypugh> It will cost me £25 if I make the pattern out of MDF.
[00:42:23] <Valen> thats dirt cheap, where are you getting the casting done?
[00:42:31] <andypugh> Birmingham
[00:42:52] <andypugh> It's cheaper than the blank in steel.
[00:42:57] <Valen> by the same token I can get 25mm offcut 6061 blocks for around $25 australian so its kinda a wash ;->
[00:43:06] <Valen> your casting it in iron or Al?
[00:43:14] <andypugh> That's 34mm thick.
[00:43:19] <andypugh> Cast iron
[00:43:24] -!- kmiyashiro has quit [Quit: kmiyashiro]
[00:43:24] <PCW> Is the spinning ball nut common in CNC machines?
[00:43:33] <Valen> nice
[00:44:27] <Valen> it isn't its used more commonly in high speed positioning systems, but I think it'll become more popular in milling type applications
[00:44:35] <andypugh> I am using castings partly because I want to keep the machine looking like Harrison made it. I am rather infected with the vintage vehicle ethos.
[00:44:47] <PCW> nicely avoids whipping for high speeds
[00:45:02] <Valen> rofl!
[00:45:22] <Valen> we are making our router/mill out of 4x4 RHS steel ;->
[00:45:42] <Valen> (the other machine the "mill" is going to be 400kg of epoxy granite)
[00:45:50] <andypugh> Exactly. And it means that the motors are not waving about with the mass and wiring issues that introduces.
[00:46:43] -!- Dale has quit [Ping timeout: 245 seconds]
[00:46:50] <Valen> I think after the whipping (which is what I'm looking at it for, over 1200 I need like 25mm screws or a 10mm lead to avoid it at only 4m/minute) the biggest impact would be on inertia
[00:47:13] <andypugh> Z axis is already rotating-nut (and working rather nicely) https://picasaweb.google.com/lh/photo/VCb5Ne6S_UTuvtR3RB_QatMTjNZETYmyPJy0liipFm0?feat=directlink
[00:48:08] <andypugh> Y-axis is rotating-screw and waiting on an 8i20 reflash :-) https://picasaweb.google.com/lh/photo/cVGGhnwqpKdGbTQADaf9HdMTjNZETYmyPJy0liipFm0?feat=directlink
[00:48:37] <Valen> we are thinking (a little) about doing an inclined bed to try to preserve some space in the shop
[00:48:48] -!- elk has quit [Ping timeout: 245 seconds]
[00:49:20] <andypugh> I do wonder why folk don't use vertical Plasma cutters
[00:49:59] <Valen> problem is parts fall down
[00:50:03] <andypugh> (On the mill, all the handles just pull off, I expect they will be kept in the cupboard)
[00:50:10] <Valen> and mounting stuff onto it
[00:50:18] <Valen> we aren't always going to do full sheets
[00:50:21] <PCW> hard to make a water tray (though I guess you could make a water curtain)
[00:50:21] <JT-Shop> kinda hard to keep the water in the table with a vertical plasma cutter
[00:50:27] <andypugh> Valen: Yes, so your CAM knows which way is up.
[00:51:01] <JT-Shop> goodnight guys
[00:51:07] <andypugh> They have almost-vertical board saws in all the big DIY sheds
[00:51:14] <PCW> 'nite
[00:51:18] <Valen> catchya
[00:52:27] <andypugh> I just noticed that in the second photo the foundry pattern is in the background. I wish I had planned it that way.
[00:53:46] -!- Nick001-Shop has quit [Remote host closed the connection]
[00:53:50] <PCW> Neat that you have a place to do castings so inexpensively
[00:54:45] <Valen> anybody here would want $200 to pick up the phone
[00:55:04] <Valen> do you have an "in" with them or is that just their usual pricing?
[00:55:57] <toastyde1th> andypugh, do you do a lot of casting?
[00:56:27] <andypugh> I personally do none. (I used to when I had a foundry at work, though :-) )
[00:56:58] <andypugh> Hmm, another reason to go back to being an academic metallurgist.
[00:57:18] <Valen> lol
[00:57:36] <toastyde1th> oh
[00:58:51] <andypugh> That is their normal pricing. I actually send my patterns to a friend who is rebuilding a 1912 truck (oldest Dennis truck extant) who has a relationship with them, but it isn't special pricing.
[01:00:32] <andypugh> That part might actually be £30 but this was definitely £100 all-in: https://picasaweb.google.com/lh/photo/3nh6qw_vccyheS13Perwa9MTjNZETYmyPJy0liipFm0?feat=directlink
[01:00:48] <Valen> no minimum order or any of that crap?
[01:00:53] <andypugh> No,
[01:01:35] <PCW> It is nice to have cast iron castings on a cast iron machine (not so sure about the orange color)
[01:01:52] <andypugh> That's primer.
[01:02:14] <andypugh> Trying to look like proper red lead.
[01:02:43] <PCW> I guess thats gone with ROHs
[01:02:51] <PCW> RoHS
[01:02:58] <andypugh> Sadly so.
[01:03:36] <PCW> Did a funny Hostmot2 config for a X-ray detector today: 96 counters
[01:04:13] <andypugh> That's both quite a lot, and baffflingly few :-)
[01:05:49] <PCW> I guess the detectors are like Geiger counters so output pulses
[01:06:46] <PCW> might be a CAT-scan type of deal
[01:08:08] <andypugh> Aye, but I thought CAT scan used a lot more channels. Perhaps not.
[01:08:10] -!- hdokes|werkin has quit [Ping timeout: 255 seconds]
[01:10:19] <andypugh> (I spent a year working in a Medical Physics department)
[01:10:53] <PCW> not sure vaguely remember seeing a gutted one at a scrap yard seemed lik it had hundreds of scintilator/PMTs
[01:11:16] <andypugh> In fact, I sometimes think I should put my CV on the Wiki in the hope that people would stop telling me stuff I know. I dont
[01:11:17] <andypugh> 
[01:12:10] <andypugh> I don't know much about coding, I don't know much about CNC. I do know a lot about materials, mechanical design, fracture mechanics, imaging and Control.
[01:12:44] <andypugh> Oh, and FEA
[01:13:59] <andypugh> (I also know very little electronics)
[01:16:29] <andypugh> What sort of rate were the counters looking at? I guess that as the CAT detector rotates then it is the position that gives the spatial resolution, and the channels that give the density data?
[01:17:22] <PCW> They are 16 bit and polled at 20 ms so 12 MHz max
[01:17:28] <andypugh> Tomography is really rather clever.
[01:18:15] <PCW> sorry 3 MHz
[01:18:38] <PCW> pulses are 100 ns wide nominally
[01:19:09] <andypugh> 12Mhz sounds quite a lot in pixel-terms. even if the combined data is only worth one pixel per scan, that's a 12Mpixel picture in 1s
[01:19:29] <andypugh> Or a 3Mpixel image. Still pretty good.
[01:19:45] <PCW> just 3 and I'm not sure how close they come to the limit
[01:19:51] <PCW> OK material scientist can you figure out how to make a wire with a negative temperature coefficient of resistance? (for foam cutting with self regulating temperature)
[01:20:17] <Valen> use a regular PTC wire with a NTC termistor in it somewhere ;-P
[01:20:49] <FinboySlick> PCW: Come on dude... Give him a real challenge and ask for a wire with negative resistance.
[01:21:03] <andypugh> http://en.wikipedia.org/wiki/Tomography
[01:21:38] <PCW> FinboySlick: this is hard enough...
[01:22:18] <andypugh> Hmm, in theory any NTC material of sufficient strength would work.
[01:23:18] <andypugh> Actually, don't you need PTC?
[01:23:33] <Jymmm> FinboySlick: You call that a challenge? HA! Try a negative resistance wire that generates 2MW/Day on nothing more than Nitrogen and/or CO2
[01:23:43] <andypugh> The current in the wire is constant, so you want higher resistance in the cold bits?
[01:23:57] <FinboySlick> Jymmm: I'll go for N, co2 isn't that abundant.
[01:24:19] <PCW> Yes
[01:25:08] <andypugh> So, normal resistance wire is close, but could usefully be _more_ P
[01:25:42] <andypugh> No, sorry, I am upside-down.
[01:26:06] <PCW> It really seem the a PTC or resistance is a basic property of metals
[01:26:07] <andypugh> (or am I?)
[01:26:15] -!- L33TG33KG34R has quit [Quit: Leaving]
[01:26:24] <PCW> yes you want NTC but metals are all PTC

[01:26:43] -!- gambakufu has quit []
[01:27:11] <PCW> semiconductors are NTC (and brittle)
[01:27:57] <PCW> No idea there were so many kinds of tomography
[01:28:56] <Valen> its good stuff
[01:29:28] <andypugh> Wiki says that NTC has been normal in underfloor heating since 1971.
[01:29:49] <Valen> I'm suprised its not used more, with modern cpus and gpus the heavy lifting should be almost trivial now
[01:30:16] <Valen> so rather than xray a fracture, why not CT it ;->
[01:30:28] <andypugh> dose.
[01:30:58] <Valen> modern detectors are that sensitive you could almost get a CT from backround radiation
[01:31:04] <Valen> might take a while but still
[01:31:15] <andypugh> Definitely a point
[01:32:54] <Valen> andypugh: got any pics of your Z?
[01:33:45] <andypugh> You mean other than the one I posted earlier?
[01:33:46] <Valen> what PCW is really trying to do is have the entire wire at the one temp regardless of the thermal load sucking heat out of various bits
[01:33:46] <jdh> we got all new whole body monitors in our change rooms last weekend. Trapped radon in synthetics set them off.
[01:33:53] <Valen> I must have missed the Z
[01:34:00] <Valen> lol
[01:34:04] <kwallace> One company I interviewed for made cooking surfaces that used the AC skin resistance and the material properties to control temperature. Heat would only go to the part of the surface that was cooler.
[01:34:27] <andypugh> This is it out of the machine: https://picasaweb.google.com/lh/photo/VCb5Ne6S_UTuvtR3RB_QatMTjNZETYmyPJy0liipFm0?feat=directlink
[01:34:32] <Valen> I like that many nuke stations have banned bannanas from their sites as the radioactive potassium in them sets off their detectors
[01:34:55] <Valen> that is one massive ass screw?
[01:35:00] <Valen> ball nut rather
[01:35:05] <andypugh> 32mm
[01:35:14] <Valen> got an image of it in place?

[01:38:12] <Valen> nice telescope thingo
[01:38:16] <andypugh> (the ball nut is above the top of the machine base, the motor is in the space below).
[01:38:21] <Valen> spring steel spiral?
[01:38:45] <Valen> so that huge cast looking bit is a housing/mount then?
[01:38:50] <andypugh> The spring cover was £50. Given what I already spent I decided to go for it.
[01:39:04] <Valen> probably worth it ;->
[01:39:19] <Valen> how are the ball nuts for ballance?
[01:39:40] <andypugh> Given that the plug in the second picture as £25...

[01:45:00] <PCW> And remember to tune to minimum PID error, not ferror
[01:45:19] <Valen> hrm?

[01:45:58] <andypugh> Oh noes! I prodded PCW's bugnear!
[01:46:08] <PCW> Yep
[01:46:31] <andypugh> Steady-state they ought to be the same.
[01:47:15] <PCW> It would not bother me except I get called on to help people tune things
[01:47:17] <PCW> yes steady state they are the same
[01:47:34] <Valen> i am curious about this tuning pid error, i haven't heard it mentioned
[01:48:06] <andypugh> Roger (With the Hardinge) is possibly the fussiest customer, but he is trying to make really tiny things.
[01:49:43] <PCW> Ferror is calculated differently than pid error (one sample different commanded position) mean you can tune the PID or tune for least Ferror but not both
[01:50:01] <andypugh> This website of his really is worth a look: http://www.f1-2000.co.uk Particularly the conrods and the fuel system.
[01:50:30] <PCW> I think this is a bug , not everyone agrees
[01:50:47] <andypugh> I am on the fence :-)
[01:51:15] <Valen> ferror i understand distance from commanded position to actual position, how is pid error different?
[01:52:51] <PCW> PID error is current commanded - current feedback Ferror is _next_ commanded - current feedback
[01:53:15] <Valen> ahh
[01:54:12] <PCW> so if you have a torque mode loop and you have enough I term to null out the PID error during a slew you will find tha you now have Ferror proportional to velocity/sample period
[01:54:32] <Valen> that could explain a few things
[01:55:15] <Valen> because I have noticed a ferror depending on velocity in cruise unless i add an assload of I
[01:56:13] <Valen> I think I'll try bumping up the cycle time for the servo thread, see if that helps things along
[01:57:38] <andypugh> Ooh! highlight of that F1-2000 website, thread-milling M2 threads in titanium using G-code because the machine can't do Y-horizontal interpoltion.
[01:57:39] <PCW> so at 240 IPM you have 4 mill error at 1 KHz sample rate when the PID is perfect
[01:58:15] <Valen> milling a 2mm thread, pretty game lol
[01:58:37] <andypugh> apparently 2mm taps just can't do Ti
[01:58:50] <PCW> I think the reason this has not caused loud complaints is that most retrofits use velocity mode drives and this error can be tuned around with FF1

[02:07:53] <L84Supper> how's that for reliability?

[05:29:23] <ssi> I'm still working through stupid turret pneumatic issues
[05:29:42] <ssi> I need to test the clippard valve that runs the airmotor and raises the turret
[05:29:56] <ssi> I guess I'll just cut its wires off midway and buttsplice them back on
[05:30:07] <ssi> I did find a place to buy the amp tools used
[05:30:13] <Jymmm> ssi: from molex type plugs?
[05:30:15] <ssi> $100 for the extractor and $75 for the insertor
[05:30:29] <ssi> Jymmm: no, these stupid amp taper pins... they're a screaming hassle
[05:30:33] <Jymmm> my extractor tools dont cost anywhere near that

[05:31:49] <Jymmm> hang on, let me grab the PN from mine
[05:34:41] <Jymmm> ssi: Ok.... These are molex, and there are three sizes of them, but they look REALLY close to what you showed me. For the cheap price of them, you might give it a shot. I use them on all kinds of molex socket, much like the 4pin powe cords in PC's and even soem amp products...
[05:34:53] <ssi> I've got molex tools
[05:34:57] <ssi> they're not even close to the same thing
[05:35:00] <Jymmm> ssi: First one... Mine is RED http://www.alliedelec.com/search/productdetail.aspx?sku=70190780
[05:35:01] <ssi> the taper pins seat with a lot of force
[05:35:12] <ssi> and they have to be pulled out
[05:35:13] <Jymmm> well, these are spring loaded
[05:35:21] <ssi> the extractor pushes against the block and pulls the pin out
[05:35:29] <ssi> the molex ones push through... it's very different
[05:35:37] <Jymmm> well, use molex then =)
[05:35:57] <ssi> it's not like I decided that hardinge should use these taper pins back in the seventies :P
[05:36:10] <Jymmm> liar
[05:36:19] <Jymmm> retrofit them
[05:36:30] <ssi> sounds like a giant hassle
[05:36:35] <ssi> it may come to that one day, but I hope not
[05:37:05] <Jymmm> There are chea alternatives now... what abotu those pluggable screw terminal strips
[05:37:28] <ssi> for where these things are located, I'm not sure what a good alternative would be
[05:37:44] <Jymmm> are they sealed?
[05:37:57] <ssi> not really
[05:38:06] <Jymmm> then n biggy
[05:38:08] <Jymmm> no
[05:38:14] <ssi> but they're very dense and in a small space
[05:38:15] <Jymmm> or use the europena type
[05:38:25] <ssi> I might be able to do it with DB connectors
[05:38:33] <ssi> but I don't know how they'll hold up
[05:38:40] <Jymmm> just signals?
[05:38:47] <ssi> I believe so
[05:39:11] <Jymmm> db is okey if you have the crimpers
[05:39:16] <ssi> I do
[05:39:34] <ssi> I do avionics work; have all mil-spec db and molex tools
[05:39:36] <Jymmm> what gauge wire?
[05:39:56] <ssi> mostly small, 20-22 prolly
[05:40:41] <ssi> anyway, the electrical's not the real problem
[05:40:43] <Jymmm> Yeah, I'd do db, cheap preltiful
[05:40:46] <ssi> the real problem is the pneumatics
[05:40:49] <Jymmm> plentiful
[05:41:04] <Jymmm> size tubing?
[05:41:07] <ssi> I'm just hung up on electrical because I need to remove a clippard valve so I can test it
[05:41:08] <Valen> we run some battery chargers through DB connectors ;->
[05:41:34] <ssi> there's this machined aluminum valve block that the clippard valve screws to
[05:41:39] <Jymmm> ssi: tubing diameter?
[05:41:43] <ssi> 1/8 or so
[05:41:56] <ssi> I had it all apart and had to replace a check valve
[05:42:03] <ssi> and now that it's back together, the valve block is venting overboard
[05:42:13] <ssi> and i think it's cause the valve is stuck in the wrong position
[05:42:15] <ssi> but I'm not sure
[05:43:02] <Jymmm> ssi: Yeah, I have no idea on that. Not something I do mass quantities of. I'd usggest JT-Shop, ut he does the fancy shit, not the cheap stuff =)
[05:43:29] <Jymmm> ssi: Oh, what about drip irrigation stuff?
[05:43:32] <ssi> jt might know about what I'm up against, since he has a similar machine
[05:43:40] <ssi> what about drip irrigation stuff

[05:44:00] <ssi> I'm trying to fix a lathe, not make something from scratch
[05:44:10] <Jymmm> just one?
[05:44:16] <ssi> just one
[05:44:27] <ssi> we're not on the same page here somewhere
[05:44:28] <ssi> heh
[05:44:55] <Jymmm> WHAT THE HELL THEN?! You paid $500 for the lathe, you have to pay $4000 for that ONE part to make it work =)
[05:45:06] <ssi> yeah been there done that
[05:45:14] <ssi> several times
[05:45:27] <archivist> molex is crap for professional work anyway
[05:45:32] <ssi> the stupid little bellows coupler that couples the leadscrew reduction to the resolvers is $88
[05:45:47] <Jymmm> ssi: I just bought an inexpensive HF Radio, But I need a antenna tuner that costs more thanthe radio
[05:45:55] <ssi> my turret quit running, got into the pneumatics and discovered a broken checkvalve which I just replaced for $260
[05:46:05] <ssi> and when I put it back together, now it's broken in a different way
[05:46:12] <ssi> and I really have NFC what I'm doing with pneumatics
[05:46:12] <Jymmm> ssi: Hey, $20 at home depot =)
[05:46:24] <ssi> what's $20 at home depot?
[05:46:32] <Jymmm> your check value =)
[05:46:32] <ssi> certainly not this hardinge-made shuttle valve
[05:46:54] <ssi> it's not that kind of valve
[05:47:17] <ssi> there's a bore in the cross slide and there's a brass body oringed that slides into the bore, with a shuttle and a piston and a spring in it
[05:47:21] <ssi> all custom made
[05:47:21] <Jymmm> ssi: Are you restoring this lathe?
[05:47:35] <ssi> no I'm not restoring it
[05:47:40] <ssi> it's a running lathe minus the current broken
[05:47:45] <Jymmm> then ghetto it =)
[05:47:48] <ssi> I'm trying to get it back running so I can do a job that I bought metal for
[05:48:07] <Jymmm> ssi: You must become one with MAcGyver
[05:48:12] <ssi> oh believe me I'd ghetto it if I could, but I don't have a good way to
[05:48:20] <Jymmm> ah
[05:48:24] <ssi> about the only ghetto option I have right now is fuck the turret and run it as a gang tool machine
[05:48:28] <ssi> which is a terrible idea
[05:49:22] <Jymmm> ssi: Well, get the current job done any way you can to get it off your mind, then walk away and come up with a practical solution
[05:49:44] <ssi> I don't really have a good way to get the current job done without fixing the lathe
[05:49:54] <ssi> or else I would have already
[05:50:05] <Jymmm> ssi: I say that becasue the next broken thing comes along and you'll be back at this again.
[05:51:28] <Jymmm> ssi: Well, good luck either way
[05:52:00] <ssi> right now I'm up against trying to decipher the pneumo schematic (which I have fortunately) and figure out how it translates to the valve block
[05:52:10] <ssi> and figure out a way to test the clippard valve that runs the valve block
[05:52:22] <ssi> in order to test it, I feel like I need to disconnect it from the terminal block
[05:52:29] <ssi> which requires either stupid tools or cutting wires and butt splicing
[05:52:57] <ssi> I don't like either option
[05:53:28] <Jymmm> how many conductors?
[05:53:34] <ssi> just 2
[05:53:44] <Jymmm> what?!
[05:53:53] <ssi> not on the whole terminal block
[05:54:00] <ssi> it's a 48 position block I think
[05:54:06] <ssi> but the clippard valve is just two conductor
[05:54:19] <Jymmm> so 48 conductors total?
[05:54:24] <ssi> yes
[05:55:20] <Jymmm> 2x db25
[05:56:00] <Jymmm> ssi: heh, punch down block
[05:56:21] <ssi> that's really not a good idea

[05:58:43] <ssi> 20 thru
[05:58:58] <Jymmm> is the plastic amp shell cheap enough?
[05:59:06] <ssi> probably not
[05:59:12] <ssi> and the freakin pins are $5 each
[05:59:27] <Jymmm> Melt/heat the plastic shell
[05:59:33] <ssi> why?
[05:59:57] <Jymmm> dremel it off, then make a useable extension for it
[05:59:57] <ssi> I want to fix this thing, not ensure it never runs again
[06:01:05] <Jymmm> would those pins fit in a db25 shell?
[06:01:09] <ssi> no
[06:01:16] <ssi> they're solid taper pins
[06:02:09] <ssi> you can see the white wire at the top right that I already had to ghettofix by soldering to the pin

[09:39:09] yuvipanda is now known as BlindSidedPanda
[09:39:11] <V0idExp> Anyone using 7i43 board? I have a problem after LinuxCNC shutdown
[09:39:26] <V0idExp> It seems that the firmware, after shutdown, pulls-up all pins to HIGH
[09:40:49] <V0idExp> how can I force it to stay down? cause it seems that with HIGH drives are enabled after linuxcnc shutdown, and any electromagnetic disturbs make them move
[09:43:05] <Jymmm> All 7I43 pins are pulled up. Its for compatibility with I/O module racks (which are active low) and because the only pre-configuration option on FPGA pins is pullup or no pullup. This is described in the STARTUP STATE section of the 7I43 manual.
[09:44:01] <V0idExp> So, as I guess, the only way is to set that option in my drives' settings? My drives are programmable via a JTAG port, and they can optionally invert the pin logic

[18:19:41] <Bruce_Tamlzn> I inquired about a finished table here in Germany but the proprietary software is only in German

[18:23:42] <Bruce_Tamlzn> http://www.ib-weigelt.de/index.php?start.php
[18:27:41] <JT-Shop> if you use a Hypertherm and go with Mesa interface cards the THCAD card is $70 in the US
[18:27:59] <IchGuckLive> this is integreadet into workbench so linuxcnc needt this to go for a userdefined Mcode
[18:28:58] <JT-Shop> so for $300 you have a 5i25 7i77 and thcad, then you need drives and servos, power supply and a computer
[18:29:31] <JT-Shop> and a closed loop servo driven plasma table with torch height control

[20:01:09] <Connor> hehe. Yea. He helped me turn down a part for my G0704 conversion. I don't have a very good lathe. He's going to re-do my pulleys. Hopefully we can help each other out.
[20:02:02] <Connor> He's converting a Arrow 500 VMC to LinuxCNC and I'm going to help him out. He's never used LinuxCNC. He was using Mach3 with his RF-45 conversion he did before he sold it to buy that Arrow500
[20:02:45] <Connor> I need to do some research into 5i25+7i77 combo using the pnconf wizard thingie.

[20:13:43] <skunkworks> Does z have to move to do a tool change? or does the arm move vertially?
[20:13:48] <skunkworks> vertically
[20:15:07] <Connor> http://www.youtube.com/watch?v=bSXR3FsN0EE&feature=plcp
[20:15:47] <Connor> It's CAT40 too, so, the spindle has to be indexed correctly too for the locking lug.
[20:15:47] <skunkworks> ugh.
[20:16:42] <Connor> skunkworks: ugh? :(
[20:17:52] <skunkworks> well - you are going to learn a lot.. In my opinion - the hardest part is going to be the z move during the tool change. TO make work seamlessly I think you would have to look seriously at gcode remapping.
[20:18:46] <Connor> I played around with the 2.6 sim with the tool change stuff.. I had it working using Z movements for a rack based system.
[20:21:10] <skunkworks> Neat - how did you do it? disconnecting motion from the axis and moving them in hal?
[20:21:15] <Connor> and that's similar to how I'm going to have mine done.. Though, I'm using Tormach tooling, so no need to index the spindle.
[20:21:28] <Connor> I dunno.. It's with the 2.6 stuff.
[20:21:45] <skunkworks> oh - I have not looked at that - maybe there is something setup already
[20:22:26] <Connor> something called remap

[20:23:45] <skunkworks> ok - so it shoudl be a cake walk :)
[20:24:32] <Connor> I hacked it to do a 4 tool rack setup.. it lowers the Z. moves the tool into the rack. raises the Z and moves over the next tool. drops down, then moves it out and the goes to home.
[20:28:12] <skunkworks> nice - you are not going to have any issues helping out pete
[20:28:41] <Connor> I've never done MESA. :( But, That shouldn't be a huge deal.
[20:29:19] <skunkworks> no - it is pretty easy - if you understand hal - it is all pins.. (and it sounds like the wizard works well - I have never used it)
[20:29:51] <Connor> Yea, the part I need to figure out is getting the wizard to see the 5i25 and 7i77 cards.
[20:30:17] <Connor> and does firmware have to up uploaded to them prior to running the wizard ?
[20:30:48] <skunkworks> umm - I think the firmware is there.. Didi you update to the latest linuxcnc version?
[20:31:10] <Connor> yes, he's running 2.6.blahblah from the repo
[20:31:55] <skunkworks> well - that is a good question. I though it should just work. exspeccially with 2.6
[20:32:45] <skunkworks> I have the older 5i20 which the firmware does get loaded during the run of linuxcnc. The 5i20 - the firmware comes installed IIRC
[20:32:50] <Connor> That was my thinking.
[20:33:10] <skunkworks> andy or peter may chime in here..
[20:38:29] <skunkworks> for sure I think the 7i77 needs field power to be recognized - but the 5i25 should be seen
[20:39:24] <PCW> You also need to download the latest xml files for pncconf to 'see' the 5I25/7I77
[20:39:36] <skunkworks> yay peter!
[20:39:48] <PCW> (look in the pncconf section of the forum)
[20:42:38] <PCW> and yes the 5I25 has on card firmware storage (you can change or update it with the mesaflash utility)

[20:43:05] <gene77> Hey guys
[20:43:24] <skunkworks> gene!
[20:44:44] <gene77> yup its me. Out here freezing my feet
[20:45:53] <gene77> I am asking trhe spindle for 600 rpm, what is the time between index pulses?
[20:48:12] <gene77> according my my calc it should be 100ms between pulses, right?
[20:48:56] <gene77> halscope says its 240 millisecs
[20:51:25] <gene77> Somewhere, I don't have the right full scale vs rpm ratio set, according to halmeter, 409 rpms is the best I can get, yet the spindle in low gear, can do around 1250 and sounds like it is.
[20:56:01] <gene77> So I put it in high gear and my accel ramp promptly cleared the fuse, put a 4 amp in and slowed the ramp 50%, and promptly shook my coffee cup off the table making several pieces out of it.
[20:56:21] <gene77> Heck It wasn't even dirty enough to need rebored yet...
[20:57:20] <gene77> But while it shook everything loose, it did show 100 mx index pulses. I think halscope is funkity

[21:11:16] <PCW> This should get straightened out when the 5i25 bitfiles get added to the linuxcnc repository (so there's a place for the xml files to go)

[22:26:54] <gene77> I adjusted the encoder.0.position-scale upward by 1.5, and it now reads 120 rpm for an index every 500 milliseconds. Kewl, but when I crank it up to what s/b 600 rpm, I show arund 250 in the halmeter, and taking the math to the calc says its actually spinning 1270 rpms!

[23:06:38] <Aero-Tec> updating to 2.5 did not fix the stopping problem
[23:06:58] -!- cevad has quit [Quit: Leaving]
[23:07:06] <Aero-Tec> skunkworks: you around?
[23:08:35] <Aero-Tec> any emc gurus?
[23:09:00] <Aero-Tec> was wondering if updating to 2.6 would be wise to do
[23:09:28] <Aero-Tec> I run my machines for profit so I need them working and reliable
[23:10:06] <roh> try on a fresh hdd.., then you can swap back without worrying
[23:10:08] <cradek> you mean master (there are no 2.6 releases yet). if you sorely need a feature that is not in 2.5, then the answer is maybe. otherwise the answer is very clearly no.
[23:10:10] <JT-Shop> unless you need a feature on 2.6, 2.5 is more stable
[23:10:10] <Aero-Tec> someone said that what the basic stuff I am doing that 2.6 would not be any problem
[23:10:29] <cradek> to me it sounds like that's answering the wrong question
[23:10:35] <Aero-Tec> what does 2.6 have that 2.5 does not?
[23:10:58] <roh> i still have a machine on 2.3.1 and its fine.. so no worries.. when its fine for you, dont touch it besides security updates
[23:11:02] <cradek> there is no 2.6. master has many many features that are under development/testing
[23:13:00] <Jymmm> ...broken as hell ;)

[23:15:02] <Aero-Tec> master is broken?
[23:15:16] <Aero-Tec> master, yes master
[23:15:18] <Aero-Tec> lol
[23:15:40] <Aero-Tec> reminds me of some horror flick
[23:16:06] <Aero-Tec> Dracula, and the like
[23:16:34] <Aero-Tec> is there a list of what they are doing to master?
[23:17:02] <JT-Shop> you might read the git log
[23:17:13] <Aero-Tec> but if it is broken I will not want to use it
[23:17:33] <Aero-Tec> the one I did read only went to 2.5
[23:17:51] <JT-Shop> you don't want to use it unless you have to have something in master
[23:19:15] <Aero-Tec> http://wiki.linuxcnc.org/cgi-bin/wiki.pl
[23:19:17] <Aero-Tec> ok
[23:20:21] <Aero-Tec> that is what I thought, so even tho I was told to use master I chickened out and did 2.5

[23:21:27] <tjb1> I normally dont read chat, its just open all the time
[23:21:43] <Aero-Tec> so I re did the SMI edit to the new config file for the upgrade
[23:21:50] <JT-Shop> worked out quite well
[23:22:08] <Aero-Tec> what else do I need to edit for the upgrade to 2.5?
[23:22:20] <JT-Shop> from?
[23:22:23] <tjb1> I like it, thcad should be here next week but I have to send g540 back saturday

[23:26:08] <Valen> JT-Shop: is it just me or is filling a bunch of mild steel with water feeling like a bad idea in terms of rust
[23:26:15] <Valen> Aero-Tec: (with your g64 issue)
[23:27:47] <Aero-Tec> the update did not change anything
[23:28:07] <Aero-Tec> have some new configs to do to see if that helps
[23:29:05] <Aero-Tec> like changing b axis to z axis and see if that blends well
[23:29:51] <Aero-Tec> I was going to see if making b axis linear would help but s guru here said it would not help
[23:29:56] <tjb1> Valen: I believe JT is using the "plasma quench" mix
[23:29:58] <JT-Shop> Valen: it is not just H2O... I've added sodium nitrite for rust and physan 20 for critters
[23:30:14] <Valen> ahh ok i was kinda wondering there lol
[23:30:38] <Valen> it should help if g64 works on 3 axis machines
[23:30:43] <Valen> how many axies do you have Aero-Tec?
[23:30:53] <JT-Shop> the sodium nitrite actually removes rust slowly
[23:30:59] <Aero-Tec> also have to try making the steps closer to the same, so instead of steps per deg I will do steps per rev
[23:31:26] P46_ is now known as fixItMark
[23:31:33] <Valen> what was the title of your post to the mailing list?
[23:32:28] <Aero-Tec> I want to do 5 moves of lin axis X and rot axis B with out stopping
[23:32:46] <Aero-Tec> does g64 work on 3 axis moves?
[23:32:55] <Aero-Tec> my mill has 4 axis
[23:33:03] <Aero-Tec> but no Z right now
[23:33:07] <Valen> that was our thinking
[23:33:17] <Valen> that its working on linear axies but not the rotary
[23:33:21] -!- servos4ever has quit [Quit: ChatZilla 0.9.85 [SeaMonkey 2.0.11/20101206162726]]
[23:33:55] <Aero-Tec> I took the Z apart when using mach, need to add it now that I have linuxcnc
[23:34:36] <Aero-Tec> you would think g64 would work with 3 axis
[23:34:53] <Aero-Tec> if so, making b linear should work
[23:35:06] <Valen> its not the number of axies, I think its the rotary vs linear axis issue
[23:35:21] <Valen> if you have 2 linears already you could test it straight away
[23:35:44] <Aero-Tec> that was why I was going to make B linear, but someone here said it would make no difference
[23:36:12] <Aero-Tec> will still try it and see
[23:36:14] <Valen> i just meant you could test it simply with no changes, see if that is the issue
[23:36:20] <Aero-Tec> so 3 things to try
[23:36:36] <Aero-Tec> make B steps per rev
[23:36:40] <Valen> well yeah just make it a linear axis and run the same g code ;->
[23:36:44] <Aero-Tec> make B linear
[23:36:56] <Aero-Tec> and move B to Z

[23:38:03] <Aero-Tec> have done the SM edit
[23:38:05] <Valen> fairy nuff
[23:38:28] <Aero-Tec> now have to rename the dir and edit the ini
[23:38:39] <Aero-Tec> looks like I do not have to edit the HAL
[23:39:24] <Aero-Tec> looks like renaming the dir and edit to INI is all that is left to do

[23:50:18] <Aero-Tec> even the new version that 2.5 put into linuxcnc dir
[23:50:38] <Aero-Tec> do I have to edit that as well?
[23:50:58] <Aero-Tec> it did start up and is running
[23:51:14] <Aero-Tec> I did not edit the INI yet or anything
[23:51:26] <Valen> if its running and moving its probably ok lol
[23:51:27] <Aero-Tec> just did the SMI edit in the rtapi.conf file
