[00:51:20] <Loetmichel> mornin'
[01:00:26] <abetusk> me gloating: http://imgur.com/myfrO
[01:07:44] <s1dev> anyone here play the violin, viola, or cello?
[01:07:55] <s1dev> wrong channel!
[02:04:06] <DJ9DJ> moin
[03:17:48] <Loetmichel> sooo.... Workdesks in front of the Measurement chamber have now Power sockets, too... and again connected while powered... dindt find the corresponding fuse ;-)... anyway, works, and no insurance man has seen it ;-)
[03:37:02] <archivist> the laws about wiring are getting silly
[03:38:19] <archivist> I was fixing some wiring up at a farm yesterday, while doing the portable items is legal, when I do the sockets next its probably illegal
[03:38:35] <archivist> even though it will be to a good standard
[06:01:58] <jthornton> http://www.cnccookbook.com/MTLaserMetrology.htm
[11:02:27] <gmouer> did you guys get that issue with the multi axis machine and smooth motion sorted out yesterday? that was some real interesting subject matter
[11:03:05] <archivist> I dont think he is sorted yet
[11:04:11] <gmouer> I picked up a trick watching using halscope to plot a velocity curve during actual cutting, slick idea
[11:06:00] <archivist> we used that when I had a problem screw cutting, made it easy to pinpoint the problem
[11:08:30] <gmouer> andypugh: my friend is going forward with his VMC retrofit with redcap motors. Right now he is sorting out the fanuc spindle motor and getting it to behave with his baldor flux-vector drive. Soon it will be on to taming the redcap motors.
[11:09:36] <andypugh> Sounds exciting :-)
[11:10:39] <archivist> andypugh, what is your ballscrew that you want rotating nut for?
[11:10:59] <archivist> speed or grunt
[11:11:09] <gmouer> the VMC is a Kryle, a beaufiful machine but no longer made, mid 90's vintage. Redcap motors on all axis and the toolchanger. Your BLDC component is making it all possible. Thanks much.
[11:12:05] <andypugh> The X axis on my Mill. And the reason I want to do it that way is for neatness of installation and so that the motor is fairly stationary (rather than waving about on the end of the bed with cables flapping in the breeze)
[11:14:36] <gmouer> my friend has old bridgeport boss with a rotating nut on the X, my bridgeport has a conventional screw and the motor hung out the end of the X. That motor lines up nicely with the knees and sometimes more important body parts.
[11:14:50] <archivist> just I have a screw and nut needing a use, probably too fat though
[11:41:32] <Connor> What's the best way to install a clean LinuxCNC ? Is there a iso with 2.5.1 on it ?
[11:41:51] <jdh> liveCD, update as needed.
[11:43:14] <Connor> so. 2.4.7 latest live Cd then.
[11:43:27] <jdh> 2.5.0 I think
[12:10:16] <IchGuckLive> hi all N)
[12:10:18] <IchGuckLive> :D
[12:10:49] <IchGuckLive> the bif freez is coming tonight 5F is expected
[12:26:11] <IchGuckLive> not many postings today
[12:26:43] <IchGuckLive> Aero-Tec: all parts milled ? Springs made
[12:29:26] <IchGuckLive> Rhinoucerus anounced today the new cam relese update for rhinocam 2012
[12:29:42] <Aero-Tec> still working on it
[12:30:05] <Aero-Tec> will report on things as I find out more info
[12:30:11] <IchGuckLive> also they got the new pricelist out Autsch 10.000USD for the master release
[12:30:49] <IchGuckLive> Aero-Tec: sdid you remove all this junk lines from the g-code
[12:31:30] <Aero-Tec> I have in one version of the code
[12:31:41] <Aero-Tec> it did nothing
[12:31:51] <Aero-Tec> no change whatsoever
[12:32:05] <Aero-Tec> or that I noticed
[12:32:08] <IchGuckLive> are you on 2.4.3
[12:32:20] <Aero-Tec> 2.5 I think
[12:32:25] <Aero-Tec> will have to check
[12:32:39] <Aero-Tec> I know I updated the lathe, not sure of the mill
[12:32:52] <Aero-Tec> will check right now
[12:32:53] <IchGuckLive> NP
[12:33:09] <Aero-Tec> if not 2.5 I will update and see if that helps
[12:36:01] <Aero-Tec> so what is the latest lock down version?
[12:36:05] <Aero-Tec> 2.51?
[12:36:27] <Aero-Tec> lathe is 2.51, mill 2.46
[12:37:02] <IchGuckLive> http://buildbot.linuxcnc.org/
[12:37:12] <IchGuckLive> why not up to date with 2.6.pre
[12:37:22] <Aero-Tec> would there be a big change in the way G64 and G93 work in the new version?
[12:38:09] <IchGuckLive> they are working all the time on it
[12:38:27] <Aero-Tec> would there not be more bugs in 2.6?
[12:38:46] <Aero-Tec> was thinking lock down would be more solid
[12:38:52] <IchGuckLive> not on your usige level
[12:39:11] <IchGuckLive> robot kinetic maybe
[12:39:35] <IchGuckLive> but you get some nice extras
[12:40:15] <Aero-Tec> after going through hell with mach and not knowing what was going to happen when I hit run or continue I am some what gun shy of anything that will or may go nuts and do it's own thing
[12:40:27] <Aero-Tec> cool
[12:40:48] <Aero-Tec> so 2.6 would be good for me to use and have no problems?
[12:41:14] <IchGuckLive> juast master pppa
[12:41:29] <Aero-Tec> what cool extras does it have?
[12:42:00] <Aero-Tec> what is master pppa?
[12:42:34] <IchGuckLive> Grid §D some new coding interpreter rewritings
[12:42:58] <IchGuckLive> 10.04 ?
[12:43:29] <Aero-Tec> I am running a intel P4
[12:43:32] <IchGuckLive> "deb http://buildbot.linuxcnc.org/ lucid master-rt" put this into your packetspource
[12:43:43] <Aero-Tec> so I am not up to date with linux
[12:43:50] <Aero-Tec> will have to check the version
[12:44:07] <Aero-Tec> it would be the version that came with 2.4
[12:52:44] <IchGuckLive> Aero-Tec: type "lsb_release -a" in a terminal without quotes
[12:54:31] <Aero-Tec> can I have 2.5 and 2.6 installed and ready to run st the same time?
[12:54:44] <Aero-Tec> could switch between them as needed
[12:55:06] <IchGuckLive> yes if you go for a git rep
[12:55:08] <Aero-Tec> If I try 2.6 would like to be able to go to 2.5 if needed
[12:55:44] <IchGuckLive> if you remove the ppa from source and then reinstrall via synaptic it goes back
[12:56:18] <IchGuckLive> it is nessesary to know if you are on 10.04 or 8.04
[12:56:49] <IchGuckLive> this is realy a MUST
[12:57:01] <Aero-Tec> I am very green to linux and EMC so I have no idea what you just said
[12:57:10] <Aero-Tec> will run the term code now
[12:57:13] <Aero-Tec> BRB
[12:57:39] <Aero-Tec> I understand about version 10 and 8
[13:00:10] <Aero-Tec> 10.04
[13:00:27] <Aero-Tec> I used to setup wed servers using linux
[13:00:35] <Aero-Tec> all remote work
[13:00:44] <IchGuckLive> :D B)
[13:00:45] <Aero-Tec> term and GUI interface
[13:00:48] <Aero-Tec> all redhat
[13:01:13] <Aero-Tec> never did it sitting in front of the computer
[13:01:28] <Aero-Tec> have no idea how to recompile
[13:01:51] <IchGuckLive> so use the ppa
[13:02:00] <IchGuckLive> did you use synaptic
[13:02:01] <Aero-Tec> I do know allot of what I do not know
[13:02:07] <Aero-Tec> no
[13:02:14] <Aero-Tec> have no idea what that is
[13:02:22] <IchGuckLive> type sudo synaptic in to a terminal
[13:02:38] <IchGuckLive> this is the packet manager
[13:03:03] <IchGuckLive> there are all the nice 250.000 free programms of linux
[13:03:14] <IchGuckLive> just a Hook away
[13:03:28] <Aero-Tec> is emc 2.6 one of them?
[13:03:38] <IchGuckLive> yes
[13:03:41] <Aero-Tec> cool
[13:03:44] <Aero-Tec> BRB
[13:04:08] <IchGuckLive> you need to ad the packetsource from buildbot and reload
[13:04:26] <IchGuckLive> then search for linuxcnc and give it a hook
[13:05:50] <IchGuckLive> press packet
[13:06:01] <IchGuckLive> then source then tirdparty
[13:06:37] <IchGuckLive> hit add and copy "deb http://buildbot.linuxcnc.org/ lucid master-rt"
[13:06:56] <IchGuckLive> into it without quotes ofcause
[13:08:45] <IchGuckLive> Aero-Tec: only update the linuxcnc nothing else maybe the doc
[13:10:43] <IchGuckLive> Aero-Tec: did you need the smi fix on your p4 then it migt be also be fixed after the newone is installed as this file is cleared
[13:13:16] <Aero-Tec> yes to SMI fix
[13:13:34] <IchGuckLive> the new version will clear this file
[13:13:46] <Aero-Tec> so I will have to redo it?
[13:13:56] <IchGuckLive> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?FixingSMIIssues
[13:14:01] <Aero-Tec> or will I nees SMI fix for the new version?
[13:14:37] <IchGuckLive> ->"/etc/linuxcnc/rtapi.conf
[13:14:50] <IchGuckLive> not more emc
[13:15:13] <Aero-Tec> right
[13:15:40] <Aero-Tec> will the update remover the EMC dir, or del the files in it?
[13:15:41] <IchGuckLive> did you manage synaptic
[13:15:47] <IchGuckLive> no
[13:16:00] <Aero-Tec> would save me doing a copy save so I have the mods made
[13:16:06] <Aero-Tec> I had it
[13:16:12] <Aero-Tec> but no linux cnc
[13:16:25] <Aero-Tec> had emc2 1.2.4.7
[13:16:37] <Aero-Tec> or something like that
[13:16:43] <IchGuckLive> if you have made changes to the standar configs in the linuxcncn folder then it is renewd
[13:16:57] <Aero-Tec> came back to tell you and I saw what I need to do to fix that
[13:17:27] <IchGuckLive> im off at :15
[13:18:00] <Aero-Tec> off for the day or will you be back later?
[13:18:20] <Aero-Tec> I will most likely be longer then 10 min
[13:18:23] <IchGuckLive> no finish for today its late here
[13:18:33] <Aero-Tec> where are you?
[13:18:34] <IchGuckLive> Berlin time
[13:18:44] <IchGuckLive> Germany
[13:18:45] <Aero-Tec> cool
[13:19:00] <Aero-Tec> thanks for all your help
[13:19:10] <IchGuckLive> NP
[13:19:11] <Aero-Tec> wish I had more time
[13:19:30] <IchGuckLive> there will be a time you might help me
[13:19:47] <Aero-Tec> I look forward to it
[13:19:54] <Aero-Tec> if I can help
[13:20:48] <Aero-Tec> will you still be logged on so I can send you info with private IRC?
[13:21:02] <IchGuckLive> no
[13:21:14] <IchGuckLive> all systewm shutdown O.O
[13:21:46] <Aero-Tec> I keep mine up 24-7
[13:22:51] <Aero-Tec> I can get back to work faster and have every thing exact as I left it
[13:24:02] <Aero-Tec> what time do you usually log in?
[13:24:52] <Aero-Tec> your new updates you gave me may work better in the new version
[13:25:25] <Aero-Tec> I had to undo all of it as the mill did not want to work as well with your setings
[13:26:14] <Aero-Tec> setting to 15000 made emc complain, so did 20000, had to go back to 25000
[13:26:15] <IchGuckLive> im herre from 1900-2015 Berlin time
[13:26:45] <IchGuckLive> 25k needs a recalculation of the step
[13:27:18] <Aero-Tec> will the update make it where 1500 will work?
[13:27:21] <Aero-Tec> maybe
[13:27:30] <Aero-Tec> 15000
[13:27:44] <Aero-Tec> times up
[13:27:46] <Aero-Tec> later
[13:28:03] <IchGuckLive> http://www.google.de/url?sa=t&rct=j&q=linuxcnc%20steptimingcalculator&source=web&cd=1&cad=rja&ved=0CC8QFjAA&url=http%3A%2F%2Fwiki.linuxcnc.org%2Fuploads%2FStepTimingCalculator.ods&ei=UIbHUILQL6KH4ASIrYCIDg&usg=AFQjCNFWYyA5VVjNMEx7FGXkIY_FVvdqzw
[13:56:33] <Jymmm> Tomorrow 12-12-12, will be the last sequential date you will ever see.
[13:58:34] <jdh> I plan on seeing the next one.
[13:58:47] <Tom_itx> so celebrate it at 12:12 PM
[13:59:13] <archivist> that would be 12 seconds early
[13:59:28] <Tom_itx> or 12:12 AM if you're up
[13:59:45] <Tom_itx> gotta start early when you're old
[14:00:27] <Jymmm> lol
[14:00:42] <Jymmm> jdh: 01-01-01 ?
[14:02:31] <jdh> yep.
[14:04:40] <andypugh> It's a good plan with a 20% chance of success.
[14:04:57] <andypugh> (20% of people are currently immortal)
[14:05:59] <Jymmm> MORTAL COMBAT!!!
[14:06:02] <archivist> just play god and rework the calender
[14:06:33] <sliptonic> Whoa! Linuxcnc just lost control of my cnc router and destroyed a piece of stock. Never saw that happen before.
[14:07:11] <archivist> define "lost control"
[14:07:21] <Jymmm> Of Mayan decent? Write the new calendar! Due date 2012-12-20
[14:08:01] <sliptonic> I've run the same job about 10 times in the last few days. This time, about half way through, the Y axis just kept on going in one direction.
[14:08:02] <cpresser> Jymmm: better: convince people to pay you money for it :)
[14:08:19] <Jymmm> cpresser: Good idea!!!
[14:08:32] <sliptonic> The backplot shows the spindle sitting in the middle not moving but the gantry was cruising at feed speed right through the material and on down the table.
[14:08:45] <sliptonic> No error.
[14:08:48] <Jymmm> cpresser: Too bad Billy Mays isn't around still
[14:09:44] <archivist> sliptonic, cable problem to the direction pin? or noise to the clock pin, check cable screens and wiring
[14:10:29] <archivist> I have also seen vfd noise get into the clock of a stepper driver
[14:11:11] * Jymmm lol @ archivist, that's funny
[14:12:13] <Jymmm> sliptonic: Are you aware that linuxcnc does NOT need a GUI to run a job?
[14:12:27] <archivist> ?
[14:12:53] <sliptonic> Hmmm. Cables look fine. Y axis motor is fixed so no cable flex. Environment is dustier than normal. No VFD on this machine. Jymmmm: yes
[14:12:54] <archivist> that has NO relation to his problem
[14:13:04] <Jymmm> sliptonic: k
[14:14:01] <Jymmm> archivist: I don't know that; maybe the GUI locked up as he said it wasn't moving on the screen but was on the machine.
[14:14:35] <sliptonic> GUI was still responsive. I hit estop there before the gantry hit the max limit.
[14:14:43] <archivist> sliptonic, here I am on about cables to the drivers rather than the driver to motor
[14:15:24] <Jymmm> and only ground one end of any shielding
[14:15:41] <sliptonic> One parallel cable from pc to controller.
[14:16:26] <Jymmm> sliptonic: Is the connector isolated on one end?
[14:17:33] <Jymmm> sliptonic: is the parallel cable shielded?
[14:17:52] <sliptonic> Jymmm: Same cable I've been running for 3 years. Shielded.
[14:21:32] <archivist> with the "right" kind of flexing I have seen cable fail in about 10 minutes, 3 years may be a long time for an amount of flexing of a cable
[14:26:12] <skunkworks> http://groups.yahoo.com/group/mach1mach2cnc/message/137742
[14:26:29] <cpresser> sliptonic: anyway, you will have to check your wiring and stepper motor-driver.
[14:26:58] <cpresser> or restart the machine and take a look at halscope and attach a multimeter to the par-port.
[14:35:09] <JT-Shop> skunkworks: did you see the guy with the hyd brake on the forum?
[14:35:25] <skunkworks> no - link?
[14:35:59] <JT-Shop> http://linuxcnc.org/index.php/english/forum/38-general-linuxcnc-questions/25937-newbie-question-about-press-brake
[14:45:22] <skunkworks> interesting... That is old school.
[14:56:16] <JT-Shop> didn't know if you could offer some insight to him about the hyd part
[14:57:56] <andypugh> Potentiometer feedback and proportioning valves, it will all look perfectly conventional to LinuxCNC
[14:58:16] <andypugh> The potentiometer feedback is actually likely to be the most difficult part.
[14:59:04] <cradek> at least a couple of our supported IO cards have adc
[15:53:25] <Jymmm> http://www.youtube.com/watch?v=7b05pf9Dqnw
[15:55:11] <DJ9DJ> gn8
[16:16:27] <cpresser> nice welding: http://www.youtube.com/watch?v=fB1BDrFzFY0&feature=player_embedded :P
[16:23:36] <tjb1> Is r00t4rd3d_ in jail yet?
[16:23:39] <tjb1> r00t4rd3d:
[16:38:21] <r00t4rd3d> ?
[16:49:25] <tjb1> PCW: Im calling.
[16:53:22] <r00t4rd3d> tjb1, wtf are you talking about?
[16:56:46] <tjb1> r00t4rd3d: Be careful with copyrighted stuff
[16:57:16] <r00t4rd3d> lol
[16:59:16] <tjb1> You be laughin till bubba finds you
[17:11:09] <r00t4rd3d> Im bubba
[17:11:33] <rob_h> well i now have a 4 axis powertooled lathe to retrofit after christmas :)
[17:11:39] <toastyde1th> that's awesome
[17:11:48] <r00t4rd3d> I got so much work to cnc for people its not funny
[17:11:48] <toastyde1th> 4 axis = two turret, or four axis = xyz + c
[17:11:54] <rob_h> two turrets
[17:12:42] <rob_h> at moments its a Index on spindle with pin lock, but thinkings i can servo that easy
[17:15:24] <rob_h> plus one of the fanucs on the mill deicded to die today so one other jogs to try and fix
[17:20:22] <JT-Shop> evening rob_h
[17:20:30] <rob_h> Hi there
[17:20:35] <rob_h> do u need some xmas work?
[17:20:39] <JT-Shop> hows it going
[17:20:48] <JT-Shop> I actually have some work in the shop
[17:21:49] <rob_h> not too bad here, never a dull day
[17:23:17] <JT-Shop> I'm reworking the plasma water table and putting the slats inside
[17:23:38] <rob_h> sounds fun
[17:23:44] <JT-Shop> http://imagebin.org/238865
[17:24:19] <jdh> did you cut the slat slots on the table?
[17:24:26] <JT-Shop> the water table was an add on after a few cuts lol
[17:24:44] <JT-Shop> on the back side or the slat supports?
[17:25:02] <jdh> I'm not sure what that means.
[17:25:12] <jdh> the slots in teh pieces
[17:26:02] <rob_h> are you sure u made it big enought tho? as u know u ways want that extra 1" for a job
[17:26:37] <JT-Shop> jdh: yes I milled the vertial slots in the slat supports
[17:26:57] <andypugh> First job for the water table, make the next set of slats...
[17:27:16] <jdh> they all look like slats to me, except for the outer frame
[17:27:17] <JT-Shop> I've had the water table for 4 years but the slats were above it
[17:30:49] <jdh> http://www.bidspotter.com/forms/staticitem.php?photo=15247649&gallery=20107
[17:31:47] <toastyde1th> you could make a water table like a turret punch
[17:31:59] <toastyde1th> no slats at all!
[17:32:54] <JT-Shop> cutting totally unneeded but aesthetically pleasing drain openings http://imagebin.org/238974
[17:33:10] <JT-Shop> dunno what that looks like
[17:33:28] <toastyde1th> ?
[17:33:53] <JT-Shop> <toastyde1th> you could make a water table like a turret punch
[17:35:09] <toastyde1th> on a turret press/punch, the cutter stays still and the material moves
[17:35:10] <toastyde1th> http://www.youtube.com/watch?v=XuIjIcgBPlY
[17:35:20] <JT-Shop> ah ok
[17:35:32] <toastyde1th> often they're integrated with lasers, too
[17:35:53] <toastyde1th> i'm pretty sure this one is
[17:36:41] <toastyde1th> nope, nvm
[17:38:20] <JT-Shop> I'm sure it would be more cost effective to continue down the path I'm on
[17:39:26] <toastyde1th> certainly less space
[17:41:16] <JT-Shop> while I'm not as challenged as archivist for space I don't have much left
[17:41:37] <rob_h> thats what u need next JT, a sheet loader, then u put ur feet up
[17:41:56] <JT-Shop> have to come through the wall...
[17:42:27] <rob_h> i dout it would be the first time done
[17:43:29] <rob_h> has any one ever converted a turret punch onto linuxcnc
[17:44:01] <JT-Shop> dunno
[17:44:25] <JT-Shop> I'd bet someone has somewhere in the world
[17:44:41] <rob_h> guys down road from us keep asking me about theres if its convertable
[17:44:56] <rob_h> as fanuc 6T is quite costly to keep fixing now days
[17:44:58] <JT-Shop> I don't see why not
[17:45:12] <JT-Shop> move to XY and punch right?
[17:45:15] <rob_h> now just the way u need to hit and move i guess
[17:45:42] <rob_h> yea thats easy just when u nibble need a cycle for it or something
[17:46:09] <toastyde1th> i'm pretty sure turret punches are too expensive to operate on a hobby scale
[17:46:21] <rob_h> im not talking hobby
[17:46:26] <toastyde1th> "hey guys look at my emc roll grinder"
[17:46:34] <toastyde1th> "pls implement crowning"
[17:47:04] <rob_h> every one needs a turret punch tho, keeps the neighbours happy at night
[17:47:12] <JT-Shop> lol
[17:48:17] <rob_h> or is that what a big power press is for
[17:48:31] <toastyde1th> forging hammer
[17:48:37] <toastyde1th> 5t drop weight
[17:49:03] <toastyde1th> that would be really funny to see an elctrohydraulic drop hammer on emc

[18:07:47] <JT-Shop> any thoughts on this http://bbs.homeshopmachinist.net/threads/18917-Qualitative-flatness-testing-cheap-%28pics%29
[18:08:28] <toastyde1th> cool idea, except the laser level is unqualified
[18:08:58] <toastyde1th> i read that article earlier and thought it was ingenious as shit
[18:10:19] <toastyde1th> he's got the reference plate, which is critical
[18:11:07] <JT-Shop> I think it is one step above a HF laser
[18:12:09] <toastyde1th> the issue i have with that method is that once you have an appropriately qualified surface (which i argue his is not), you already have a faster and easier method to check flatness of parts
[18:12:33] <toastyde1th> though i am sure it's indespensible in some cases
[18:14:04] <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?
[18:14:24] <toastyde1th> oh, for sure.
[18:14:39] <toastyde1th> in the general sense
[18:14:54] <toastyde1th> I can't think of a situation where that's the metric, though
[18:15:07] <tjb1> JT-Shop: Honey, dinner is ready
[18:15:12] <JT-Shop> lol
[18:15:27] <toastyde1th> cutting rails, etc
[18:15:38] <toastyde1th> you know the general cross-sectional error
[18:15:43] <toastyde1th> but not enough to actually fix anything
[18:15:54] <tjb1> JT-Shop: I ordered THCAD today.
[18:16:33] <tjb1> Pleasantly surprised that they offered student pricing
[18:17:39] <JT-Shop> I'm still waiting for my epicurean delight...
[18:18:38] <tjb1> Where is the thc.comp located?
[18:24:49] <JT-Shop> que?
[18:25:18] <JT-Shop> it is installed with LinuxCNC
[18:26:22] <JT-Shop> http://www.youtube.com/watch?v=jGqrvn3q1oo
[18:29:37] <Tom_itx> laser levels are used in ship building
[18:30:04] <Tom_itx> assuredly a bit more accurate than the one above
[18:31:27] <tjb1> so as long as I give it the correct pins in HAL, I can just loadrt thc and be done?
[18:31:35] <JT-Shop> anyone want to help me wrestle the plasma water table back into place
[18:31:44] <JT-Shop> aye
[18:32:08] <toastyde1th> i will
[18:32:17] <toastyde1th> I was planning on going to the gym then I started drinking
[18:32:20] <toastyde1th> so i guess that's not happening
[18:32:28] <toastyde1th> might as well wrestle with a water table instead of deadlifts
[18:32:29] <tjb1> Is it setup to use the emcmot encoder?
[18:34:17] <tjb1> http://www.linuxcnc.org/media/kunena/attachments/legacy/files/thc.comp
[18:35:02] <JT-Shop> ?
[18:35:27] <JT-Shop> http://linuxcnc.org/docs/devel/html/man/man9/thc.9.html
[18:36:24] <PCW> you will have to add the encoder comp and wire its velocity out to the thc comp
[18:38:01] <tjb1> Reading
[18:38:05] <tjb1> :)
[18:38:13] <PCW> the man page is a bit more specific than it needs to be (any encoder velocity signal should work)
[18:38:58] <PCW> you will also need to jumper the THCAD so it generates a frequency that the software encoder counter can read
[18:40:02] <tjb1> Which part determines where the jumper is set?
[18:40:08] <tjb1> The frequency the BOB can transmit?
[18:40:43] <PCW> probably your base thread frequency
[18:41:40] <JT-Shop> this? HAL Plasma Connections hm2_5i20.0.encoder.00.velocity => thc.encoder-vel
[18:41:48] <PCW> which determines how fast the inputs can be sampled
[18:42:37] <PCW> Yes. You may also need a low-pass filter to get enough resolution with the software encoder
[18:43:17] <PCW> encoder.velocity --> lowpass--> THC input
[18:43:19] <tjb1> So that would end up being something like parport.1.encoder.00.velocity => thc.encoder-vel
[18:43:25] <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?
[18:43:40] <tjb1> Valen, wasnt that Aero-Tec
[18:43:44] <Valen> yeah
[18:43:57] <Valen> I'm going to get a rotary soon so i'm somewhat interested too
[18:44:11] <PCW> Not that I know of, Andy had a nice video demo of the bug
[18:45:15] <Valen> I suggested a workaround for his paticular issue by using the rotary axis as a linear but its much less than ideal
[18:45:53] <PCW> JT-Shop, yes it should work with any encoder input tha has decent velocity estimation though you may need a low-pass filter
[18:46:31] <tjb1> PCW - parport.1.encoder.00.velocity => thc.encoder-vel?
[18:46:47] <tjb1> Well thats using parport 1 and it doesnt have an encoder pin so scratch that.
[18:46:57] <Valen> andypugh: you are playing with rotating ballnuts hrm?
[18:47:00] <PCW> Yes but like I said you will likely need a lowpass in there
[18:47:34] <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
[18:47:55] <tjb1> PCW: software filter?
[18:48:00] <tjb1> http://linuxcnc.org/docs/html/man/man9/lowpass.9.html
[18:48:12] <andypugh> I am, and my machine already has one fitted and working.
[18:48:18] <PCW> Yep
[18:48:21] <JT-Shop> PCW: I'll make the wording less specific in the morning
[18:48:22] <Valen> home made or off the shelf?
[18:48:47] <andypugh> As I see it they are 100% equivalent and you should choose which way you go on the basis of other factors.
[18:49:04] <JT-Shop> at the time it was monkey see monkey do...
[18:49:23] <Valen> I figured the lube arrangement may well be different as could the returns given all that spinning
[18:52:02] <andypugh> This is option 1 (trailer wheel bearing) https://picasaweb.google.com/lh/photo/EqgIdXH-kCH8I90oYKfm2dMTjNZETYmyPJy0liipFm0?feat=directlink
[18:52:23] <andypugh> Inventor crashed part way through option 2
[18:53:19] <andypugh> (Not as complex as it might look, one casting, 2 turned parts)
[18:53:39] <andypugh> Green is the ballscrew
[18:53:55] <andypugh> Time to find out what is left of option 2
[18:53:58] <Valen> I'd probably just mill out the "casting"
[18:54:23] <Valen> the reason I'm interested is we are doing a half sheet mill/router and want some decent speeds
[18:54:30] <andypugh> It will cost me £25 if I make the pattern out of MDF.
[18:54:44] <Valen> thats dirt cheap, where are you getting the casting done?
[18:54:51] <andypugh> Birmingham
[18:55:13] <andypugh> It's cheaper than the blank in steel.
[18:55:18] <Valen> by the same token I can get 25mm offcut 6061 blocks for around $25 australian so its kinda a wash ;->
[18:55:26] <Valen> your casting it in iron or Al?
[18:55:34] <andypugh> That's 34mm thick.
[18:55:39] <andypugh> Cast iron
[18:55:45] <PCW> Is the spinning ball nut common in CNC machines?
[18:55:53] <Valen> nice
[18:56:47] <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
[18:56:56] <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.
[18:57:08] <PCW> nicely avoids whipping for high speeds
[18:57:23] <Valen> rofl!
[18:57:43] <Valen> we are making our router/mill out of 4x4 RHS steel ;->
[18:58:03] <Valen> (the other machine the "mill" is going to be 400kg of epoxy granite)
[18:58:10] <andypugh> Exactly. And it means that the motors are not waving about with the mass and wiring issues that introduces.
[18:59:11] <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
[18:59:33] <andypugh> Z axis is already rotating-nut (and working rather nicely) https://picasaweb.google.com/lh/photo/VCb5Ne6S_UTuvtR3RB_QatMTjNZETYmyPJy0liipFm0?feat=directlink
[19:00:28] <andypugh> Y-axis is rotating-screw and waiting on an 8i20 reflash :-) https://picasaweb.google.com/lh/photo/cVGGhnwqpKdGbTQADaf9HdMTjNZETYmyPJy0liipFm0?feat=directlink
[19:00:58] <Valen> we are thinking (a little) about doing an inclined bed to try to preserve some space in the shop
[19:01:41] <andypugh> I do wonder why folk don't use vertical Plasma cutters
[19:02:20] <Valen> problem is parts fall down
[19:02:23] <andypugh> (On the mill, all the handles just pull off, I expect they will be kept in the cupboard)
[19:02:30] <Valen> and mounting stuff onto it
[19:02:38] <Valen> we aren't always going to do full sheets
[19:02:42] <PCW> hard to make a water tray (though I guess you could make a water curtain)
[19:02:42] <JT-Shop> kinda hard to keep the water in the table with a vertical plasma cutter
[19:02:48] <andypugh> Valen: Yes, so your CAM knows which way is up.
[19:03:21] <JT-Shop> goodnight guys
[19:03:28] <andypugh> They have almost-vertical board saws in all the big DIY sheds
[19:03:35] <PCW> 'nite
[19:03:39] <Valen> catchya
[19:04:47] <andypugh> I just noticed that in the second photo the foundry pattern is in the background. I wish I had planned it that way.
[19:06:11] <PCW> Neat that you have a place to do castings so inexpensively
[19:07:05] <Valen> anybody here would want $200 to pick up the phone
[19:07:24] <Valen> do you have an "in" with them or is that just their usual pricing?
[19:08:18] <toastyde1th> andypugh, do you do a lot of casting?
[19:08:48] <andypugh> I personally do none. (I used to when I had a foundry at work, though :-) )
[19:09:19] <andypugh> Hmm, another reason to go back to being an academic metallurgist.
[19:09:39] <Valen> lol
[19:09:56] <toastyde1th> oh
[19:11:11] <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.
[19:12:53] <andypugh> That part might actually be £30 but this was definitely £100 all-in: https://picasaweb.google.com/lh/photo/3nh6qw_vccyheS13Perwa9MTjNZETYmyPJy0liipFm0?feat=directlink
[19:13:08] <Valen> no minimum order or any of that crap?
[19:13:13] <andypugh> No,
[19:13:56] <PCW> It is nice to have cast iron castings on a cast iron machine (not so sure about the orange color)
[19:14:13] <andypugh> That's primer.
[19:14:35] <andypugh> Trying to look like proper red lead.
[19:15:03] <PCW> I guess thats gone with ROHs
[19:15:11] <PCW> RoHS
[19:15:18] <andypugh> Sadly so.
[19:15:57] <PCW> Did a funny Hostmot2 config for a X-ray detector today: 96 counters
[19:16:33] <andypugh> That's both quite a lot, and baffflingly few :-)
[19:18:10] <PCW> I guess the detectors are like Geiger counters so output pulses
[19:19:07] <PCW> might be a CAT-scan type of deal
[19:20:29] <andypugh> Aye, but I thought CAT scan used a lot more channels. Perhaps not.
[19:22:40] <andypugh> (I spent a year working in a Medical Physics department)
[19:23:13] <PCW> not sure vaguely remember seeing a gutted one at a scrap yard seemed lik it had hundreds of scintilator/PMTs
[19:23:37] <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
[19:23:37] <andypugh> 
[19:24:31] <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.
[19:25:05] <andypugh> Oh, and FEA
[19:26:20] <andypugh> (I also know very little electronics)
[19:28:49] <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?
[19:29:43] <PCW> They are 16 bit and polled at 20 ms so 12 MHz max
[19:29:49] <andypugh> Tomography is really rather clever.
[19:30:36] <PCW> sorry 3 MHz
[19:30:58] <PCW> pulses are 100 ns wide nominally
[19:31:29] <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
[19:31:50] <andypugh> Or a 3Mpixel image. Still pretty good.
[19:32:06] <PCW> just 3 and I'm not sure how close they come to the limit
[19:32:12] <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)
[19:32:37] <Valen> use a regular PTC wire with a NTC termistor in it somewhere ;-P
[19:33:10] <FinboySlick> PCW: Come on dude... Give him a real challenge and ask for a wire with negative resistance.
[19:33:24] <andypugh> http://en.wikipedia.org/wiki/Tomography
[19:33:58] <PCW> FinboySlick: this is hard enough...
[19:34:39] <andypugh> Hmm, in theory any NTC material of sufficient strength would work.
[19:35:39] <andypugh> Actually, don't you need PTC?
[19:35:53] <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
[19:36:04] <andypugh> The current in the wire is constant, so you want higher resistance in the cold bits?
[19:36:18] <FinboySlick> Jymmm: I'll go for N, co2 isn't that abundant.
[19:36:39] <PCW> Yes
[19:37:28] <andypugh> So, normal resistance wire is close, but could usefully be _more_ P
[19:38:02] <andypugh> No, sorry, I am upside-down.
[19:38:26] <PCW> It really seem the a PTC or resistance is a basic property of metals
[19:38:27] <andypugh> (or am I?)
[19:38:45] <PCW> yes you want NTC but metals are all PTC
[19:39:32] <PCW> semiconductors are NTC (and brittle)
[19:40:18] <PCW> No idea there were so many kinds of tomography
[19:41:17] <Valen> its good stuff
[19:41:49] <andypugh> Wiki says that NTC has been normal in underfloor heating since 1971.
[19:42:10] <Valen> I'm suprised its not used more, with modern cpus and gpus the heavy lifting should be almost trivial now
[19:42:37] <Valen> so rather than xray a fracture, why not CT it ;->
[19:42:48] <andypugh> dose.
[19:43:18] <Valen> modern detectors are that sensitive you could almost get a CT from backround radiation
[19:43:24] <Valen> might take a while but still
[19:43:36] <andypugh> Definitely a point
[19:45:15] <Valen> andypugh: got any pics of your Z?
[19:46:05] <andypugh> You mean other than the one I posted earlier?
[19:46:07] <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
[19:46:07] <jdh> we got all new whole body monitors in our change rooms last weekend. Trapped radon in synthetics set them off.
[19:46:13] <Valen> I must have missed the Z
[19:46:21] <Valen> lol
[19:46:24] <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.
[19:46:48] <andypugh> This is it out of the machine: https://picasaweb.google.com/lh/photo/VCb5Ne6S_UTuvtR3RB_QatMTjNZETYmyPJy0liipFm0?feat=directlink
[19:46:52] <Valen> I like that many nuke stations have banned bannanas from their sites as the radioactive potassium in them sets off their detectors
[19:47:15] <Valen> that is one massive ass screw?
[19:47:21] <Valen> ball nut rather
[19:47:26] <andypugh> 32mm
[19:47:34] <Valen> got an image of it in place?
[19:49:24] <andypugh> Above: https://picasaweb.google.com/lh/photo/-R-_lHTLAgQoSoQ_-iSQ19MTjNZETYmyPJy0liipFm0?feat=directlink below: https://picasaweb.google.com/lh/photo/aYPO3qxw_rZ5vjw9A4-CS9MTjNZETYmyPJy0liipFm0?feat=directlink
[19:50:33] <Valen> nice telescope thingo
[19:50:36] <andypugh> (the ball nut is above the top of the machine base, the motor is in the space below).
[19:50:42] <Valen> spring steel spiral?
[19:51:05] <Valen> so that huge cast looking bit is a housing/mount then?
[19:51:11] <andypugh> The spring cover was £50. Given what I already spent I decided to go for it.
[19:51:24] <Valen> probably worth it ;->
[19:51:39] <Valen> how are the ball nuts for ballance?
[19:52:00] <andypugh> Given that the plug in the second picture as £25...
[19:53:08] <andypugh> I think balance is irellevant in this case. Given what they are connected to, and how fast they actually turn.
[19:53:29] <Valen> I am going to be doing ~1000RPM or more to hit 4 meters a minute
[19:53:45] <kwallace> This is a knee mill and the motor is in the foot?
[19:54:03] <andypugh> My Z is 2000m/min at the moment, and that scares me.
[19:54:27] <andypugh> (f-error is a bit big, but part of that is Chris's Axis bug)
[19:56:04] <andypugh> I though I had 0.18mm steady state error, which is horrible, bit actualy Chris had made Axis convert twice,and it was really .007mm)
[19:56:42] <andypugh> I was really scratching my head about why the PID wasn't doing anything,
[19:57:11] <Valen> heh oops
[19:57:21] <PCW> And remember to tune to minimum PID error, not ferror
[19:57:40] <Valen> hrm?
[19:57:48] <andypugh> kwallace: Yes. Motor inside the base, rotating nut. I wanted an almost-invisible conversion.
[19:58:18] <andypugh> Oh noes! I prodded PCW's bugnear!
[19:58:28] <PCW> Yep
[19:58:52] <andypugh> Steady-state they ought to be the same.
[19:59:36] <PCW> It would not bother me except I get called on to help people tune things
[19:59:38] <PCW> yes steady state they are the same
[19:59:54] <Valen> i am curious about this tuning pid error, i haven't heard it mentioned
[20:00:26] <andypugh> Roger (With the Hardinge) is possibly the fussiest customer, but he is trying to make really tiny things.
[20:02:04] <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
[20:02:21] <andypugh> This website of his really is worth a look: http://www.f1-2000.co.uk Particularly the conrods and the fuel system.
[20:02:50] <PCW> I think this is a bug , not everyone agrees
[20:03:07] <andypugh> I am on the fence :-)
[20:03:36] <Valen> ferror i understand distance from commanded position to actual position, how is pid error different?
[20:05:11] <PCW> PID error is current commanded - current feedback Ferror is _next_ commanded - current feedback
[20:05:36] <Valen> ahh
[20:06:32] <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
[20:06:52] <Valen> that could explain a few things
[20:07:35] <Valen> because I have noticed a ferror depending on velocity in cruise unless i add an assload of I
[20:08:33] <Valen> I think I'll try bumping up the cycle time for the servo thread, see if that helps things along
[20:09:59] <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.
[20:10:00] <PCW> so at 240 IPM you have 4 mill error at 1 KHz sample rate when the PID is perfect
[20:10:35] <Valen> milling a 2mm thread, pretty game lol
[20:10:57] <andypugh> apparently 2mm taps just can't do Ti
[20:11:11] <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
[20:11:44] <andypugh> I recently bought a set of taps, everything from 4.5mm to 0.7mm :-)
[20:11:46] <Valen> Ti will often work harden which will pose an issue
[20:11:59] <PCW> bbl gents
[20:13:58] <Valen> catchya
[20:17:43] <andypugh> Well. Looks like Inventor/Windows lost everything, so roatating nut V2 will be tomorrow.
[20:17:54] <Valen> windows, king of fail
[20:17:54] <andypugh> Night all
[20:18:05] <Valen> night, thanks for the images
[20:19:10] <L84Supper> I backup any CAD at least every few hours on Windoze
[20:20:06] <L84Supper> Solidworks even has a 20 minute nag timer now reminding you to backup the file you are working on...
[20:20:14] <L84Supper> how's that for reliability?
[20:20:40] <Valen> wont autosave?
[20:20:54] <L84Supper> it has that as well
[20:20:58] <toastyde1th> lol that always seems so absurd
[20:21:14] <toastyde1th> we have 200+ gb of storage and a network connection
[20:21:33] <toastyde1th> yet a several hundred dollar piece of software can't figure out how to adaquately recover from failure
[20:21:51] <toastyde1th> yet an open source database can do that fairly gracefully
[20:22:37] <L84Supper> over the years I've only lost data to either a virus or a corrupted HD controller
[20:22:45] <Valen> nasty
[20:47:15] <Jymmm> linux dont have virus
[20:48:51] <Valen> there have been
[20:50:02] <alex4nder> yes.
[20:50:45] <Tom_itx> if it's code, it can be hacked
[23:21:45] <ssi> ugh, I sometimes wonder wtf I was thinking screwing around with old machines
[23:23:01] <ssi> anyone have any tips on how to remove amp taper pins from terminal blocks withoun the $600 removal tool?
[23:39:29] <cradek> ssi: use sidecutters to cut the wire near the end of the pin, unscrew terminal blocks and discard, then use a soldering iron for reinstallation
[23:41:36] <ssi> I don't really want to have to redo the whole terminal block
[23:41:44] <ssi> I'm still working through stupid turret pneumatic issues
[23:42:03] <ssi> I need to test the clippard valve that runs the airmotor and raises the turret
[23:42:16] <ssi> I guess I'll just cut its wires off midway and buttsplice them back on
[23:42:27] <ssi> I did find a place to buy the amp tools used
[23:42:34] <Jymmm> ssi: from molex type plugs?
[23:42:35] <ssi> $100 for the extractor and $75 for the insertor
[23:42:50] <ssi> Jymmm: no, these stupid amp taper pins... they're a screaming hassle
[23:42:53] <Jymmm> my extractor tools dont cost anywhere near that
[23:43:01] <Jymmm> ssi: link?
[23:43:05] <Jymmm> or pic?

[23:44:10] <Jymmm> hang on, let me grab the PN from mine
[23:47:01] <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...
[23:47:13] <ssi> I've got molex tools
[23:47:17] <ssi> they're not even close to the same thing
[23:47:21] <Jymmm> ssi: First one... Mine is RED http://www.alliedelec.com/search/productdetail.aspx?sku=70190780
[23:47:22] <ssi> the taper pins seat with a lot of force
[23:47:33] <ssi> and they have to be pulled out
[23:47:34] <Jymmm> well, these are spring loaded
[23:47:41] <ssi> the extractor pushes against the block and pulls the pin out
[23:47:49] <ssi> the molex ones push through... it's very different
[23:47:58] <Jymmm> well, use molex then =)
[23:48:18] <ssi> it's not like I decided that hardinge should use these taper pins back in the seventies :P
[23:48:31] <Jymmm> liar
[23:48:40] <Jymmm> retrofit them
[23:48:51] <ssi> sounds like a giant hassle
[23:48:55] <ssi> it may come to that one day, but I hope not
[23:49:25] <Jymmm> There are chea alternatives now... what abotu those pluggable screw terminal strips
[23:49:48] <ssi> for where these things are located, I'm not sure what a good alternative would be
[23:50:04] <Jymmm> are they sealed?
[23:50:17] <ssi> not really
[23:50:27] <Jymmm> then n biggy
[23:50:29] <Jymmm> no
[23:50:34] <ssi> but they're very dense and in a small space
[23:50:35] <Jymmm> or use the europena type
[23:50:46] <ssi> I might be able to do it with DB connectors
[23:50:53] <ssi> but I don't know how they'll hold up
[23:51:01] <Jymmm> just signals?
[23:51:08] <ssi> I believe so
[23:51:32] <Jymmm> db is okey if you have the crimpers
[23:51:36] <ssi> I do
[23:51:55] <ssi> I do avionics work; have all mil-spec db and molex tools
[23:51:56] <Jymmm> what gauge wire?
[23:52:17] <ssi> mostly small, 20-22 prolly
[23:53:02] <ssi> anyway, the electrical's not the real problem
[23:53:04] <Jymmm> Yeah, I'd do db, cheap preltiful
[23:53:07] <ssi> the real problem is the pneumatics
[23:53:09] <Jymmm> plentiful
[23:53:24] <Jymmm> size tubing?
[23:53:28] <ssi> I'm just hung up on electrical because I need to remove a clippard valve so I can test it
[23:53:29] <Valen> we run some battery chargers through DB connectors ;->
[23:53:55] <ssi> there's this machined aluminum valve block that the clippard valve screws to
[23:53:59] <Jymmm> ssi: tubing diameter?
[23:54:04] <ssi> 1/8 or so
[23:54:17] <ssi> I had it all apart and had to replace a check valve
[23:54:24] <ssi> and now that it's back together, the valve block is venting overboard
[23:54:34] <ssi> and i think it's cause the valve is stuck in the wrong position
[23:54:36] <ssi> but I'm not sure
[23:55:22] <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 =)
[23:55:50] <Jymmm> ssi: Oh, what about drip irrigation stuff?
[23:55:52] <ssi> jt might know about what I'm up against, since he has a similar machine
[23:56:01] <ssi> what about drip irrigation stuff
[23:56:07] <Jymmm> echo echo
[23:56:14] <ssi> I don't know what you're suggesting
[23:56:20] <ssi> I'm trying to fix a lathe, not make something from scratch
[23:56:30] <Jymmm> just one?
[23:56:36] <ssi> just one
[23:56:48] <ssi> we're not on the same page here somewhere
[23:56:48] <ssi> heh
[23:57:16] <Jymmm> WHAT THE HELL THEN?! You paid $500 for the lathe, you have to pay $4000 for that ONE part to make it work =)
[23:57:27] <ssi> yeah been there done that
[23:57:35] <ssi> several times
[23:57:48] <archivist> molex is crap for professional work anyway
[23:57:52] <ssi> the stupid little bellows coupler that couples the leadscrew reduction to the resolvers is $88
[23:58:08] <Jymmm> ssi: I just bought an inexpensive HF Radio, But I need a antenna tuner that costs more thanthe radio
[23:58:15] <ssi> my turret quit running, got into the pneumatics and discovered a broken checkvalve which I just replaced for $260
[23:58:26] <ssi> and when I put it back together, now it's broken in a different way
[23:58:32] <ssi> and I really have NFC what I'm doing with pneumatics
[23:58:33] <Jymmm> ssi: Hey, $20 at home depot =)
[23:58:45] <ssi> what's $20 at home depot?
[23:58:52] <Jymmm> your check value =)
[23:58:52] <ssi> certainly not this hardinge-made shuttle valve
[23:59:15] <ssi> it's not that kind of valve
[23:59:38] <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
[23:59:42] <ssi> all custom made
[23:59:42] <Jymmm> ssi: Are you restoring this lathe?
[23:59:55] <ssi> no I'm not restoring it
