[00:07:32] <JymmmEMC> yo
[00:10:31] <skunkworks> yo?
[00:10:46] <JymmmEMC> yo ho ho and a bottle of TEQUILIA!
[00:11:55] <skunkworks> That sound good. I am wiped. They guys came today to backfill the frostwalls. That wasn't supposed to happen until tomorrow.
[00:12:18] <skunkworks> That required me to get the foam on the frostwalls quicker than expected.
[00:12:42] <skunkworks> we are getting a winter storm here tomorrow so they wanted to get it done today
[00:12:54] <JymmmEMC> well, that's cool.
[00:13:01] <JymmmEMC> at least they were thinking ahead
[00:13:12] <skunkworks> one more thing to cross off the list
[00:13:16] <skunkworks> yes
[00:13:37] <JymmmEMC> backfill. as in sunked garage?
[00:13:43] <JymmmEMC> sunkin
[00:13:45] <Skullworks-PGAB> * Skullworks-PGAB wants a snow free weekend
[00:14:16] <skunkworks> the frost wall have to be below frost line here - 4 feet
[00:14:17] <JymmmEMC> Skullworks-PGAB: head south fo the equator
[00:14:36] <JymmmEMC> skunkworks: what does that serve?
[00:14:45] <JymmmEMC> other than pipes freezing
[00:14:51] <skunkworks> no heaving
[00:15:12] <JymmmEMC> the concrete itself you mean?
[00:15:24] <JymmmEMC> I'm confused
[00:15:28] <Skullworks-PGAB> yeah 25 degrees and falling with snow overnight forecast.
[00:16:29] <JymmmEMC> Shit, this might be worht it... rated at 16A instead of the 10A I see everywhere else http://www.campbelldesigns.com/parallel-port-relay-board.php
[00:16:51] <Skullworks-PGAB> I'm heading to Los Angeles for christmas - much warmer.
[00:17:05] <JymmmEMC> Skullworks-PGAB: bring your shorts with ya
[00:17:20] <Skullworks-PGAB> I always do...
[00:17:24] <JymmmEMC> =)
[00:17:26] <christel> [Global Notice] Hi all! To those of you relying on tor for connections to freenode I am terribly sorry to inform you that non tor-gpg (http://freenode.net/irc_servers.shtml#tor) connections have been blocked. This block may be in place for at least a number of days while we try to deal with systematic abuse. Again, I apologise for the inconvenience and hope that we will find a solution soon. Thank you for using freenode and have a good day!
[00:17:54] <Skullworks-PGAB> must get in some quality jacuzzi time.
[00:18:18] <JymmmEMC> Skullworks-PGAB: No clothing allowed in the jacuzzi
[00:19:38] <Skullworks-PGAB> that depends on which - that would not fly at one friends apt building with kids running around.
[00:20:07] <JymmmEMC> Too bad the US is so weird about nudity, unlike EU
[00:21:09] <JymmmEMC> Though, some ppl look better with their clothes on , than off =)
[00:21:20] <Skullworks-PGAB> very true
[00:21:38] <toastydeath> naked people are a sin
[00:22:04] <JymmmEMC> toastydeath: ?
[00:23:21] <JymmmEMC> Man, I wish cambpbell put out for detailed specs
[00:23:27] <JymmmEMC> more
[00:23:55] <JymmmEMC> Like which pins his relay board uses
[00:23:58] <Skullworks-PGAB> jym you plan on buying both the breakout and the relay expansion brd?
[00:24:18] <JymmmEMC> Skullworks-PGAB: I'm thinking about it, would save some wiring
[00:24:25] <Skullworks-PGAB> 1 sec
[00:25:57] <JymmmEMC> It's the only relay board I've seen that does > 10A. I need at least 13A for the initial spike.
[00:26:32] <JymmmEMC> Though I have to email him and ask is that resistive or inductive rating.
[00:30:42] <Skullworks-PGAB> I think thats the continuous rating
[00:31:11] <Skullworks-PGAB> http://www.lococnc.com/catalog/product_info.php?cPath=21_43&products_id=36 is a cheap relay board
[00:31:16] <fenn> JymmmEMC: it's the impedance rating! :)
[00:31:43] <JymmmEMC> Skullworks-PGAB: 7A on that relay board =(
[00:31:47] <JymmmEMC> fenn: are you sure?
[00:31:59] <JymmmEMC> for an inductive load I mean.
[00:32:16] <fenn> i'm just yanking your antenna
[00:32:26] <JymmmEMC> k
[00:32:54] <JymmmEMC> I have a relay here that's rated at 20A resistive load, but much less for an inductive load is why I ask.
[00:33:29] <archivist> arcing on opening the contacts
[00:34:05] <archivist> due to back emf from the inductance
[00:34:29] <JymmmEMC> archivist: it makes sense, just most relays are not labeled for inductive load.
[00:35:07] <archivist> motor relays are allways inductive rated
[00:35:16] <JymmmEMC> really?
[00:36:53] <Skullworks-PGAB> use a 7a to switch a 20A SSR
[00:37:28] <JymmmEMC> Skullworks-PGAB: I'm trying to KISS, I could use a SSR directly w/o a relay board.
[00:38:58] <Skullworks-PGAB> http://www.mpja.com/prodinfo.asp?number=16596+RL
[00:39:22] <Skullworks-PGAB> that could be switched directly
[00:39:36] <JymmmEMC> Skullworks-PGAB: http://cgi.ebay.com/Solid-State-Relays-SSR-24-220V-DC-40A-Heat-Sink_W0QQitemZ230196341640QQihZ013QQcategoryZ78207QQcmdZViewItem
[00:40:06] <JymmmEMC> comes with heat sink too
[00:42:48] <Skullworks-PGAB> I need a SSR that DPDT
[00:42:52] <JymmmEMC> Their verbage confuses me a bit though.... "Load could not be inductive type" I thought you COULD use SSR with an inductive load?
[00:43:35] <archivist> ssr can be triggered with the back emf
[00:43:48] <archivist> hence the restriction
[00:43:55] <skunkworks> JymmmEMC: yes - keeps the concrete from moving around
[00:44:14] <JymmmEMC> archivist: so, it's NOT a good idea to use a SSR on a spindle?
[00:44:22] <JymmmEMC> On/OFF
[00:44:26] <Skullworks-PGAB> Jym - Item location: nanjing,jiangsu, China
[00:44:51] <archivist> if rated for motors it would be ok
[00:45:02] <Skullworks-PGAB> be ready for a 6-8 week delivery time
[00:45:03] <JymmmEMC> Skullworks-PGAB: Yeah, so I'm not sure if it's just the chinglish, or something else.
[00:45:26] <JymmmEMC> Skullworks-PGAB: I've gotten shipments from china in 8 days
[00:46:26] <Skullworks-PGAB> I have ordered direct from china before - on single part orders they filled in the customs paperwork as a free sample/gift
[00:46:40] <JymmmEMC> I emailed Campbell, so we'll see about his relay board.
[00:46:52] <JymmmEMC> Skullworks-PGAB: Yeah, same here.
[00:47:01] <Skullworks-PGAB> he responds pretty fast usually
[00:54:19] <Skullworks-PGAB> I have an SCR based DC speed control - it does not provide a way to reverse the motor
[00:55:13] <Skullworks-PGAB> was going to use a DPDT to handle polarity switching
[00:56:51] <Skullworks-PGAB> with a pair of beefy diodes to protect the SCR from back EMF
[01:00:36] <Skullworks-PGAB> The Online Tool for Precision Vectorization - http://vectormagic.stanford.edu/
[01:15:03] <fenn> is it any better than potrace?
[01:16:32] <Skullworks-PGAB> don't know - I have been avoiding graphic issues since I have someone I can pawn the work off on..
[01:17:39] <Skullworks-PGAB> I a G code writer - not a master of solid models or graphics
[01:17:56] <eric_U> anyone know a cheap source for lm297s?
[01:18:30] <Skullworks-PGAB> why 297's?
[01:18:49] <eric_U> cause I already have 298's
[01:19:16] <Skullworks-PGAB> there are better things to drive a 298
[01:19:34] <eric_U> not if you bought a board that takes 297's
[01:19:46] <Skullworks-PGAB> true
[01:19:57] <eric_U> what else would you use?
[01:21:33] <Skullworks-PGAB> just like the current limiting and micro step options -
[01:21:54] <Skullworks-PGAB> not sure if it was a LM6203 or some such
[01:22:23] <Skullworks-PGAB> one is listed in the 298 data sheet - let me dig it up here
[01:22:25] <eric_U> I have some drives that seem to use a pic or the like
[01:26:15] <Skullworks-PGAB> LM6506
[01:26:36] <Skullworks-PGAB> to handle current chopping
[01:26:52] <Skullworks-PGAB> so no resistors..
[01:27:28] <Skullworks-PGAB> drive it with a PIC to provide microstepping
[01:27:54] <Skullworks-PGAB> or drive it with a 297 in half step
[01:28:08] <fenn> i wonder if the ADC on a PIC or similar chip would be fast enough to do current sensing on a microstepping drive
[01:28:20] <fenn> iirc its about 15khz sample rate
[01:28:34] <eric_U> msp430 is supposed to be able to sample at 200kHz
[01:29:30] <eric_U> but do you really have to sample that fast? Low pass filter etc
[01:30:29] <fenn> well, 15khz is about 1 sample per step
[01:30:42] <fenn> per full step
[01:32:07] <fenn> the scheme i came up with was to use PWM or some crude r2r DAC to set the desired current level, and then a simple comparator to actually switch the bridge on and off
[01:35:51] <eric_U> well, this is just a throw away project, I bought boards from pminmo
[01:36:13] <fenn> might as well finish it
[01:36:53] <eric_U> I want to be able to make circuit boards, so it's not really throw away
[01:36:58] <eric_U> just not high performance
[01:37:16] <fenn> jameco has l297 for $5.19, so i dunno if that's cheap
[01:37:27] <eric_U> that's better than mouser
[01:37:53] <fenn> futurlec $3.80 but you will be waiting a few weeks
[01:38:07] <eric_U> tempting
[01:38:17] <eric_U> what's the deal with them?
[01:38:24] <fenn> and they have a hidden money conversion charge because they're based in australia
[01:38:36] <eric_U> i see, can't afford it then
[01:38:54] <eric_U> U.S. Peso to Australian Dollar is a big problem
[01:39:01] <fenn> i'm pretty happy with jameco for most things
[01:39:34] <eric_U> as long as surplus is ok, which it is
[01:41:10] <eric_U> I miss midwest surplus
[01:41:20] <eric_U> http://www.midwestsurplus.net/
[01:43:17] <jmkasunich> It's true - dogs do have cold noses: http://jmkasunich.com/pics/hot-dog.jpg
[01:44:28] <fenn> what are you doing with an infrared camera?
[01:44:39] <fenn> (besides taking pictures of your dog)
[01:44:42] <jmkasunich> looking for heat leaks
[01:45:05] <fenn> i assume you're renting it - how much does that cost?
[01:45:22] <jmkasunich> borrowing it from work
[01:48:16] <jmkasunich> crappy door: http://jmkasunich.com/pics/back-door.jpg
[01:48:33] <jmkasunich> more crap: http://jmkasunich.com/pics/sliding-door.jpg
[01:49:17] <fenn> seems like it would be smarter to look at the house from the outside
[01:49:25] <jmkasunich> gonna do that too
[01:49:33] <jmkasunich> different approaches for different things
[01:49:57] <jmkasunich> for example, if you are looking for air leaks to weatherstrip (like around doors and windows) it is much clearer from inside
[01:51:38] <jmkasunich> the family room is absolutely horrible
[01:51:47] <jmkasunich> it has beautiful solid wood paneling
[01:51:53] <jmkasunich> with apparently nothing behind it
[01:52:05] <jmkasunich> there is cold air leaking in at half the joints
[01:52:16] <fenn> can you blow in cellulose from the attic?
[01:52:26] <jmkasunich> no attic in that area
[01:52:40] <jmkasunich> plus, unknown vintage wiring, possible knob-n-tube
[01:52:45] <fenn> yum
[01:52:57] <jmkasunich> not a good idea to blow in around knob-n-tube wiring
[01:53:10] <jmkasunich> the worst leaks are at the baseboards and window frames
[01:53:31] <jmkasunich> I'm gonna remove the boards and window trim and see if some great-stuff foam helps
[01:55:27] <jmkasunich> * jmkasunich takes a pry bar into the family room.... this could be messy
[01:57:28] <fenn> my solution to the cold house problem is to get a new house :\
[01:57:46] <jmkasunich> that takes a lot of money
[01:57:59] <jmkasunich> besides, I'd have to move several tons of tools and machinery
[01:58:33] <fenn> you are a better cobbler than I :)
[02:00:59] <skunkworks> for the windows - use the low expanding stuff
[02:02:51] <skunkworks> (otherwise you may never get them open again;))
[02:53:53] <LawrenceG> friday night an all the mice are frozen in their beds....
[03:07:26] <jepler> hi LawrenceG
[03:09:42] <jepler> LawrenceG: I am interested in whether estop works like you initially expected it to when you reverse this patch: http://cvs.linuxcnc.org/cvs/emc2/src/emc/usr_intf/stepconf/stepconf.py.diff?r1=1.16;r2=1.15
[03:20:19] <LawrenceG> Hi Jeff... havent tried it.... give me a minute to make the change..... hardware is still hooked up
[03:29:08] <LawrenceG> bbl... phone call
[03:30:26] <jepler> LawrenceG: I'm leaving for the night but I'll scroll back tomorrow
[03:30:34] <toastydeath> why do people throw a shitfit over the rules on practicalmachinist
[03:30:44] <LawrenceG> ok.... I'll post my results
[03:48:09] <LawrenceG> jepler: results: putting the old line back in makes estop work the way I think it should (like current documentation)
[03:48:33] <JymmmEMC> jepler: working on estop?
[03:49:36] <LawrenceG> jepler: F1, charge pump starts putting out pulses... user pulls in external estop loop, emc sees estop ok then allows F2 and so on.. pushing F1 estops external loop as expected
[03:51:58] <JymmmEMC> LawrenceG: where/how you seeing the chargepump pulses?
[03:52:30] <LawrenceG> I think the confusion is what the estop-in signal is.... does it reflect status of external estop loop? or is it a request from outside to estop?... I think it should be status... if user has a real estop loop, it should do the stopping without computer being involved
[03:53:29] <JymmmEMC> estop-in.notify
[03:53:46] <LawrenceG> JymmmEMC: pulses are on my pin17 which triggers the watchdog chip on my breakout board
[03:54:05] <JymmmEMC> LawrenceG: Right, but does it have an LED or something?
[03:54:31] <JymmmEMC> do you have a scope on the pin?
[03:54:57] <LawrenceG> yes... there is a flashing console light when the watchdog chip times out.
[03:55:17] <LawrenceG> and of course the estop relay bangs open
[03:55:38] <JymmmEMC> LawrenceG: console, as in CRT?
[03:56:23] <JymmmEMC> LawrenceG: do you have a wiring diagram for your setup? I need some ideas.
[03:56:36] <LawrenceG> sorry, I have a mini operators console with the estop mushroom and a lighted pushbutton (indicator for computer watchdog status and press for feed override)
[03:57:06] <JymmmEMC> LawrenceG: pics?
[03:57:18] <LawrenceG> JymmmEMC: i'll post some...
[03:57:22] <JymmmEMC> k
[03:58:03] <JymmmEMC> I still need to get pilot lights still, found some LED based ones that take various voltages I might consider. still need to figure out the control voltages I want to use though.
[03:59:01] <LawrenceG> http://imagebin.ca/view/2oVEhX.html is a fuzy shot of everything wired up on the bench
[03:59:13] <JymmmEMC> looking...
[03:59:54] <JymmmEMC> so, which is the chargepump iditot light?
[04:00:05] <LawrenceG> big transformer is +45 supply for steppers
[04:00:15] <LawrenceG> top of box is all a/c wiring
[04:00:20] <LawrenceG> bottom is all DC
[04:00:59] <LawrenceG> green push button is on steady when emc is running and F1 has been pushed to bring computer out of estop
[04:01:17] <LawrenceG> flashes if there is no charge pump pulses
[04:01:30] <JymmmEMC> how did you get it to flash?
[04:01:31] <LawrenceG> and is off if the computer is not powered up
[04:01:43] <JymmmEMC> and what doe sthe green button do?
[04:02:48] <LawrenceG> it is actually the ouput of the watchdog chip driving a solid state relay.... when light is on, there is steady voltage available to run the control power (estop) circuit
[04:03:49] <JymmmEMC> so, the chargepump signal is toggling an SSR?
[04:04:05] <LawrenceG> when the chargepump pulses stop, the watchdog chip drops its output low for about 1/2 second every second (it was made to reset a micro)
[04:04:28] <LawrenceG> this causes an estop
[04:04:44] <LawrenceG> let me post pdf of a/c wiring....
[04:04:48] <JymmmEMC> k
[04:04:56] <JymmmEMC> LawrenceG: I think I'm going to get this http://www.campbelldesigns.com/parallel-port-relay-board.php
[04:05:17] <JymmmEMC> LawrenceG: the contacts are rated for 16A, which is what I need. and a bit less wiring.
[04:05:50] <LawrenceG> now why wont imagbin take pdf's? says invalid format
[04:06:05] <JymmmEMC> try zshare.net
[04:06:10] <LawrenceG> can you open autocad .dwg files?
[04:06:28] <JymmmEMC> not atm
[04:08:37] <LawrenceG> hey zshare.net does the upload, but crashes the browser trying to pop up advertising
[04:08:55] <JymmmEMC> what browser?
[04:09:10] <LawrenceG> firefox
[04:09:24] <JymmmEMC> works for me
[04:09:36] <JymmmEMC> disable popups in it
[04:10:02] <LawrenceG> I get the link for the file... buts its trying to grab some more advertising...
[04:10:27] <JymmmEMC> no idea
[04:13:01] <LawrenceG> http://www.zshare.net/download/5287643ebb1c05/
[04:13:28] <LawrenceG> some womens magazine ad was blowing up firefox... worked in epiphany
[04:16:15] <LawrenceG> I havent updated the drawing yet for the grren light... it is actual feed from wire #1 at the top of the ladder instead of from the push button
[04:16:30] <JymmmEMC> LawrenceG: Ok, I see the two SSR connected to the on/off/auto switch. When they say "to pc..." that's really the sginal FROM the pc?
[04:17:25] <LawrenceG> top one is driven by the watchdog chip, bottom 2 are driven by the buffered i/o from the breakout board
[04:18:26] <LawrenceG> if you give me a second, I'll try and update the dwg...
[04:18:27] <JymmmEMC> LawrenceG: Right but the signal source is the PC TO the SSR, correct?
[04:19:05] <JymmmEMC> It's just a verbage thing, but the labels should say FROM PC, and not TO PC
[04:19:07] <LawrenceG> yes... PC parallel port -> breakout board -> SSR
[04:21:00] <LawrenceG> I will update that as well
[04:21:22] <JymmmEMC> and you only using a half bridge?
[04:21:29] <JymmmEMC> and you are only using a half bridge?
[04:23:11] <LawrenceG> yes... with CT transformer it gives me about 45vdc... which is actually a little high for my 1.7v steppers
[04:48:51] <LawrenceG> Hi JymmmEMC ... I am still here... autocad in progress
[05:02:15] <LawrenceG> JymmmEMC: http://www.zshare.net/download/5288321c67251e/ updated... as built drawing
[05:14:29] <fenn> nice drawing
[05:20:05] <LawrenceG> fenn: thanks... with this stuff, I need to keep notes and its just as easy to design and build from good notes
[05:48:10] <JymmmEMC> I agree, and steal your ideas =)
[05:51:33] <LawrenceG> standard stuff modified to use stuff in my junkbox.... oh ya... "all smoke, fires, natural disasters resulting from the operation of said device(s) are the responsibility of the operator!"
[05:52:36] <JymmmEMC> No problem... have 15A resetable breakers already =)
[05:53:35] <LawrenceG> stepconf is pretty neat... been a few glitches that I am trying to work out.... my mist coolant control dissappeared from axis... need to find out what that keys off of
[05:54:53] <JymmmEMC> Oh hell....
[05:55:37] <JymmmEMC> The breakout board should be mounted on standoffs.
[05:55:37] <JymmmEMC> The relays should only be use up to 10 amps. The relays should work OK with
[05:55:37] <JymmmEMC> an inductive load.
[05:55:37] <JymmmEMC> For higher currents I recommend using a solid-state relay controlled by the
[05:55:37] <JymmmEMC> breakout board.
[05:56:03] <JymmmEMC> Then wth do you advertise 16A argh
[05:56:37] <LawrenceG> pcb traces for 16 amps get interesting
[05:57:07] <JymmmEMC> Maybe so, but I should n't have to ask about such things.... imagine someone not knowing.
[05:58:00] <JymmmEMC> We ALL know that relays in this context are gonna be controlling something inductive... be it a pump or motor
[05:59:07] <JymmmEMC> ok, Las Vegas is coming on bbl
[05:59:29] <LawrenceG> ttyl
[07:14:29] <LawrenceG> jepler: can you please have a look at patch http://pastebin.ca/803470 ... it adds compumotor device and coolant(s) to stepconfig
[07:18:58] <LawrenceG> jepler: next step is to get a lathe config working using stepconf.... it is current complaining of a previously connected signal
[08:12:31] <JymmmEMC> LawrenceG: what were you uisng the contactors for again? dorect to the outlets?
[13:03:58] <jlmjvm> alex_joni:good morning

[14:48:30] <jlmjvm> jepler:check this out
[14:48:34] <jlmjvm> http://pastebin.com/d7555240f
[14:49:29] <jepler> anything specific I am supposed to look at?
[14:50:07] <jlmjvm> no,it actually works,just wanted to show ya the progress
[14:50:18] <jepler> ok good
[14:52:33] <jepler> LawrenceG: pastebin.ca isn't loading right now so I can't look at whatever it was you pasted.
[14:58:54] <Dogfishguzzler> jepler: Yeah I'm really paying attention here lol
[15:18:55] <Dogfishguzzler> It's been years since I used IRC, forgive me for being ignorant.
[15:20:18] <Ziegler> hehe
[15:20:44] <Ziegler> Its not been years for me... and I still have problems in the ignorant arena.
[16:59:07] <jepler> it's nasty out there! about 1/4in ice on everything. yay winter weather.
[17:06:38] <JymmmEMC> even Calif got butt cold last night...
[17:07:27] <JymmmEMC> 36 was the low last night
[17:08:46] <JymmmEMC> jepler: do you have to plug in your car where your at?
[17:33:11] <jlmjvm> jepler:where do you live?
[17:46:19] <awallin> how about this for a toolpath ? :) http://www.jumpcut.com/view?id=B13D0C5CA03411DCBEEC000423CF382E
[17:53:36] <jepler> jlmjvm: nebraska
[17:53:42] <jepler> JymmmEMC: no it doesn't get that cold
[17:55:02] <jlmjvm> alabama
[18:01:39] <LawrenceG> jepler: did pastebin.ca come alive?
[18:02:15] <LawrenceG> logger_emc: bookmark
[18:02:15] <LawrenceG> Just this once .. here's the log: http://www.linuxcnc.org/irc/irc.freenode.net:6667/emc/2007-12-01.txt
[18:03:00] <jepler> LawrenceG: not from here
[18:04:10] <LawrenceG> hmmm.. seems to be hanging here as well... I'll see if I can repost to .com
[18:05:01] <LawrenceG> need to boot emc computer....
[18:11:52] <LawrenceG> jepler: http://pastebin.com/m4f709f5b
[18:13:38] <jepler> LawrenceG: thanks
[18:13:39] <LawrenceG> jepler: adds to tort.ngc for lost step detection... stepconf oem750 drive type, stepconf coolant additions
[18:14:25] <JymmmEMC> New standard response... http://imagebin.org/index.php?mode=image&id=12104
[18:14:43] <LawrenceG> jepler: the glade patch is a little messy as I poked around in some of the fields.... better to add manually
[18:15:41] <SWPadnos> SWPadnos says, jymmm is a nut-case
[18:16:01] <JymmmEMC> SWPadnos: who the hell are you?
[18:16:16] <SWPadnos> oh, allow me to introduce myself.
[18:16:22] <SWPadnos> I'm the traveling sick person
[18:16:37] <JymmmEMC> Ah, ok
[18:17:03] <SWPadnos> except I'm actually home for a few hours today
[18:18:13] <JymmmEMC> woohoo!
[18:18:21] <CIA-23> 03jepler 07v2_2_branch * 10emc2/nc_files/tort.ngc: make tort more useful for detecting lost position during its run
[18:18:43] <CIA-23> 03jepler 07TRUNK * 10emc2/nc_files/tort.ngc: merge from branch: make tort more useful for detecting lost position
[18:19:15] <JymmmEMC> SWPadnos: hope you feel better
[18:19:23] <LawrenceG> jepler: stepconf is quite a big project.... very nice to use for tweaking machine config
[18:19:25] <SWPadnos> me too
[18:20:40] <jepler> I started it because I thought it was pretty small .. but time is proving me wrong.
[18:21:16] <SWPadnos> JymmmEMC, you may need to be sitting down for this, but I'm actually sick enough that I've skipped dinner for the last 6 days
[18:21:38] <JymmmEMC> ouch, that seems to be going around
[18:22:44] <SWPadnos> it was a little funny on one of the flights I was on - I was coughing a lot, then I got a nosebleed on top of it all. I'm sure the person next to me thought I had something like TB
[18:23:19] <jepler> LawrenceG: spotted one problem: now the drive type defaults to parker instead of other .. easy to fix
[18:24:40] <CIA-23> 03jepler 07v2_2_branch * 10emc2/debian/changelog: stepconf fixes and improvements: parker oem750 driver timings. fix coolant mist/flood pins.
[18:24:41] <CIA-23> 03jepler 07v2_2_branch * 10emc2/src/emc/usr_intf/stepconf/ (stepconf.glade stepconf.py): stepconf fixes and improvements: parker oem750 driver timings. fix coolant mist/flood pins.
[18:25:29] <CIA-23> 03jepler 07TRUNK * 10emc2/src/emc/usr_intf/stepconf/ (stepconf.glade stepconf.py): merge from branch: parker driver timings, coolant pins
[18:25:41] <jepler> LawrenceG: thanks
[18:26:55] <eric_U> tomp here?
[18:27:41] <eric_U> oh, he's not even logged in
[18:27:50] <JymmmEMC> SWPadnos: Or a biological weapon
[18:28:20] <SWPadnos> oh yeah - the "12 Monkeys" scenario
[18:28:21] <eric_U> doesn't sound good, I've never skipped dinner that long
[18:28:36] <eric_U> you can call me late, just don't call me late for dinner
[18:28:49] <JymmmEMC> SWPadnos: any international flights you on?
[18:28:58] <SWPadnos> no
[18:29:19] <SWPadnos> I got sick in NY, then went to Indianapolis and Miami
[18:29:21] <JymmmEMC> bummer, i could have said your canook and then enacted the war time bs
[18:29:23] <SWPadnos> via Chicago
[18:29:56] <SWPadnos> then my uncle died, so I'm headed out to Maryland tonight so I can go to the funeral tomorrow
[18:30:05] <JymmmEMC> sorry to hear that
[18:30:27] <SWPadnos> yeah - he was a really cool guy. 80 years old though
[18:31:11] <JymmmEMC> ah
[18:32:50] <SWPadnos> JymmmEMC, we'll need to set up some time to get your machine running. I'm thinking January is a good time
[18:33:08] <SWPadnos> I thought about doing it this year, but I think I'd like to rest a little
[18:33:35] <LawrenceG> jepler: I will beat on stepconf today for lathe config.... I am glad to help with patches
[18:34:21] <jepler> LawrenceG: I expect to encounter the following problem: stepconf doesn't ask the maximum speed at which you want to track the spindle. It bases the base_period choice off the step rate required. so you have no way of making sure base_period is low enough to track the spindle
[18:35:23] <jepler> bbl
[18:36:18] <LawrenceG> jepler: ok, I will keep an eye open.... I have hardware for pwm of spindle speed and also spindle encoder feedback.... I take it that the current config is NOT using this for servoing speed control, but just for locking co-ordinated moves
[18:55:53] <Dogfishguzzler> You guys no anything about small stepper motors? How can I tell if it's bipolar, unipolar etc?
[18:55:58] <Dogfishguzzler> know*
[18:56:17] <SWPadnos> if it has 4 wires, it's bipolar
[18:56:26] <SWPadnos> 5 wires probably means unipolar
[18:56:26] <Dogfishguzzler> ok, it does.
[18:56:31] <SWPadnos> ok
[18:56:32] <Dogfishguzzler> I got them from a printer
[18:56:58] <SWPadnos> you can use a battery to find out the coil configuration
[18:57:10] <SWPadnos> like a D cell or even an AA for small motors
[18:57:19] <Dogfishguzzler> Now, can I some how use the control board from the printer? Maybe jumper the cable the way you do when you play with floppy steppers?
[18:57:39] <Dogfishguzzler> For use with EMC of course
[18:57:40] <SWPadnos> depends on the control board
[18:57:47] <SWPadnos> probably not, but maybe
[18:57:53] <Dogfishguzzler> Can you point me to some docs?
[18:58:05] <SWPadnos> on the control board?
[18:58:18] <Dogfishguzzler> On how to modify them, acually nm.
[18:58:30] <SWPadnos> heh - nope
[18:58:32] <Dogfishguzzler> Now that I know they are bipolar I can build a board
[18:59:31] <Dogfishguzzler> Lol one more question for ya, Iv'e looked at a few schematics. Do you know where I might find a quick and dirty design for experimentation?
[18:59:56] <SWPadnos> fora bipolar driver - there are probably some simple designs on the CCED yahoo group
[19:00:06] <SWPadnos> CCED = CAD_CAM_EDM_DRO
[19:00:20] <Dogfishguzzler> Thanks, I will check that out.
[19:00:29] <SWPadnos> also, jepler here has a simple driver I think - look around on axis.unpy.net (I think)
[19:00:36] <Dogfishguzzler> Sucks I can't use the printers board
[19:00:57] <SWPadnos> you might be able to, but you'd have to figure out how it gets commands from the micro in the printer
[19:01:23] <Dogfishguzzler> Yeah thats sounds harder than building one.
[19:01:24] <SWPadnos> step/dir, quadrature, serial commands, velocity commands, etc.
[19:01:27] <SWPadnos> probably
[19:01:44] <Dogfishguzzler> I'm not that bored lol.
[19:05:20] <Dogfishguzzler> axis.unpy.net has lots of good stuff. Good link man I owe you a beer.
[19:06:35] <eric_U> I just bought some of the pminmo l297/l298 boards for experimentation
[19:06:55] <eric_U> you can also hang out on ebay, if my ebay skills were sharper that would have been cheaper
[19:07:25] <eric_U> missed a couple of drivers for $20 because I had to go to the Mil's house on thanksgiving
[19:09:02] <eric_U> problem with printer boards is that they have been engineered to save the last $.000001 cent
[19:09:17] <eric_U> no general purpose applicability
[19:19:10] <Dogfishguzzler> I'm looking around now for schematics that are really part intensive. I'm thinking of just buying a board and being done with it.
[19:19:25] <Dogfishguzzler> that arent' parts intensive*
[19:21:54] <eric_U> it can be done with a darlington array and some resistors
[19:22:57] <alex_joni> hey SWampy :)
[19:23:05] <alex_joni> back already?
[19:25:53] <Dogfishguzzler> eirc: Do you think I could build the circuit on an experimenters board or would I need to go all out and solder to pcb?
[19:25:54] <eric_U> rough motion with steppers means you have to change the step/dir hold times?
[19:26:12] <eric_U> you could definitely use a experimenters board
[19:26:36] <Dogfishguzzler> Now to find a good schematic that I can follow lol
[19:26:37] <eric_U> I meant to ask about rough motion with Geckos
[19:27:01] <jlmjvm> what kinda gecko
[19:27:26] <eric_U> 201
[19:27:30] <alex_joni> eric_U: what motors, what's your voltage?
[19:27:44] <eric_U> sorry, I'm trying to help somebody on cnczone
[19:27:52] <eric_U> http://www.cnczone.com/forums/showthread.php?t=47905
[19:28:15] <eric_U> he talks about changing accel and speeds
[19:28:20] <eric_U> but not hold times
[19:32:33] <jlmjvm> check the input,output scale
[19:33:48] <jlmjvm> also the accel times
[19:34:13] <jlmjvm> too high a number will stall a stepper
[19:36:14] <eric_U> scale would have the same effect as too high accel value
[19:45:38] <Dogfishguzzler> Quick question about the kits on hobbycnc. I noticed they do not come with a 10A transformer, what's the transformer for anyway?
[19:48:46] <jepler> http://en.wikipedia.org/wiki/Transformer
[19:49:52] <SWPadnos> http://imdb.com/title/tt0418279/
[19:50:24] <jepler> (it provides electrical isolation and lowers the voltage to a range acceptable by the motor driver)
[19:51:21] <Dogfishguzzler> Oh, I knew that lol. For some reason I thought it was for something else.
[19:51:44] <Dogfishguzzler> They should have put in my terms and said power supply
[19:52:35] <Dogfishguzzler> I can find one good link with schematics for controlling and driving bipolar steppers. These things seem as good as useless.
[19:52:44] <Dogfishguzzler> I cant'* find one good link
[19:57:02] <eric_U> you kids are very funny
[19:57:09] <eric_U> no get off my lawn
[19:57:15] <eric_U> now
[19:59:35] <eric_U> Dogfishguzzler: stepper drivers are out there, simple ones that work are pretty common
[19:59:41] <eric_U> problem comes when you want performance
[20:00:09] <eric_U> then you would be silly not to buy a gecko
[20:01:53] <Dogfishguzzler> Yeah at this point I would like to not buy anything. This is my chance to learn that way when I do want performance I'll have some clue as to what that means.
[20:15:42] <notranc> the best thing to do is learn from others: http://www.stepperworld.com (tutorials)
[20:16:02] <Skullworks-PGAB> Dogfishguzzler: Did you say the stepper was a 5 wire?
[20:16:07] <notranc> search for stepper motor driver on google and you'll find links like http://www.doc.ic.ac.uk/~ih/doc/stepper/control2/connect.html
[20:25:08] <eric_U> notranc: that's pretty funny, I have a board just like that in my basement
[20:27:26] <eric_U> my milling machine just refused a connection, I'm going to go give it a kick
[21:05:23] <eric_U> don't understand why I can't enable sshd on my emc machine, grumble
[21:05:51] <alex_joni> any errors?
[21:06:12] <eric_U> I did /etc/ssh/sshd restart
[21:06:28] <eric_U> I guess I have to fix configuration somehow?
[21:06:38] <alex_joni> did it work before?
[21:06:48] <eric_U> I have had it working
[21:07:20] <eric_U> don't remember how, I thought it was just apt-get install sshd and then it worked
[21:07:27] <eric_U> but it's been a few months
[21:07:56] <Skullworks-PGAB> Os Alex, was there a bug (bad file) on the LiveCD or just a bad checksum figure?
[21:08:17] <Skullworks-PGAB> * Skullworks-PGAB is typing dislyxic
[21:08:24] <Skullworks-PGAB> So
[21:12:25] <acemi> /etc/init.d/ssh restart
[21:13:22] <acemi> and the package name is openssh-server
[21:14:53] <alex_joni> Skullworks-PGAB: bad checksum figure
[21:15:02] <alex_joni> afaik the livecd runs & installs fine
[21:18:31] <Skullworks-PGAB> I think I might wipe my old Breezy box and start fresh.
[21:20:07] <Skullworks-PGAB> I'll but it on my 2008 to-do list.
[21:20:35] <Skullworks-PGAB> * Skullworks-PGAB really needs his first cup of coffee
[21:36:55] <notranc> eric_U first thing to check is log files. /var/log/auth.log in ubuntu case. second, try to run daemon manually with -d and -D options; also read man sshd pages
[21:41:02] <Dogfishguzzler> Skullworks-PGAB: No it's 4 wire.
[21:41:56] <eric_U> turns out that ssh doesn't work if you use the wrong IP address, who knew?
[21:42:23] <notranc> no kidding?
[21:42:52] <eric_U> that's just wrong, linux is so user-unfriendly
[21:42:53] <eric_U> :)
[21:43:21] <alex_joni> eric_U: you just need to populate /etc/hosts with all misstypings of the host name you mean
[21:43:26] <notranc> that's why DNS was invented. has nothing to do with "linux" or unix
[21:43:47] <eric_U> notranc: sorry, just being silly
[21:43:57] <Skullworks-PGAB> PEBKAC
[21:44:09] <notranc> I know but I'm very seriuos all the time :-)
[21:45:05] <eric_U> I don't know if my router will set up a dns table
[21:45:42] <eric_U> need a new one anyway

[21:46:12] <CIA-23> 03tissf 07TRUNK * 10emc2/src/po/fr_rs274_err.po: French translation
[21:46:27] <notranc> My router is Linux box with "everything", dns, www, dhcp, mysql, email, so life is good
[21:46:40] <eric_U> I'd like to keep the power draw down
[21:47:19] <eric_U> plus I am mostly wireless
[21:47:27] <eric_U> too lazy to pull that many wires
[21:47:30] <notranc> that's a compromise, have everything at home in my garage or pay somebody else for hosting
[21:47:54] <alex_joni> eric_U: get a NSLU
[21:48:28] <alex_joni> NSLU2 to be precise :)
[21:48:52] <eric_U> I have some of those at work, used for wireless network bridges
[21:49:16] <alex_joni> you can put debian on one, along with dns, www, dhc, whatever
[21:49:39] <eric_U> I suspect that is what they are doing, stinkin' things are closed source
[21:50:10] <alex_joni> nope
[21:50:22] <alex_joni> http://www.nslu2-linux.org/
[21:50:26] <eric_U> sorry, I meant the ones I'm using at work
[21:50:59] <alex_joni> eric_U: that's why I said a "nslu2" not any router :)
[21:51:40] <eric_U> I was thinking open-wrt since it has wireless built in
[21:51:54] <alex_joni> that works too :)
[21:52:12] <alex_joni> although this one seems a bit more extendible (with 2 USB's)
[21:52:18] <alex_joni> one for a wireless stick, the other for a HDD
[21:52:31] <CIA-23> 03tissf 07v2_2_branch * 10emc2/docs/src/gcode/tool_compensation_fr.lyx: French translation
[21:52:39] <eric_U> range of wireless stick might not be enough
[21:52:57] <eric_U> would be nice to have a hard drive

[22:20:29] <cradek> whee!
[22:20:45] <alex_joni> yay release
[22:20:56] <JymmmEMC> Yeah Easter!
[22:21:24] <tomp2> i dont have tab completion in halcmd, what governs that? gnome terminal?
[22:21:36] <alex_joni> alex_joni has changed the topic to: Welcome! EMC (Enhanced Machine Controller) is a linux-based opensource CNC control. | Latest release: EMC 2.2.2 | http://www.linuxcnc.org | http://wiki.linuxcnc.org
[22:21:55] <Skullworks-PGAB> woot
[22:26:30] <eric_U> tomp, I posted your m5i20 spreadsheet on cnczone, is that ok with you?
[22:27:35] <tomp2> eric_u: fine, but lemme see url so i can review
[22:27:47] <eric_U> http://www.cnczone.com/forums/showthread.php?t=47939
[22:27:51] <tomp2> thx
[22:31:44] <tomp2> eric_U: the area near AK82 was a scar heap of signals i hadnt used
[22:31:52] <tomp2> scrap
[22:33:53] <eric_U> yeah, I saw that but it's very useful
[22:34:11] <eric_U> I was going to draw a schematic, but it's really tough, and not as useful
[22:35:47] <tomp2> hunt, you can draw connecting lines in OO spreadsheets, tho other users may loose that in translation to W$ formats
[22:35:53] <tomp2> hint
[22:36:08] <eric_U> that would be nice
[22:40:55] <Hugomatic> alex_joni: my Synaptic package manager is unaware of the existence of EMC 2.2.2. Is this normal or should I be doing something to see it?
[22:41:25] <eric_U> did you install the upgrade to 2.2.1?
[22:41:42] <eric_U> if not, you need to follow the steps on the wiki
[22:41:44] <Hugomatic> eric_U: yes, I have 2.2.1
[22:42:20] <eric_U> Hugomatic: I dunno then, I was too lazy to install 2.2.1, only went to 2.2.2
[22:43:01] <Hugomatic> Also, I don't see mention of 2.2.2 on the website. Am I stuck in the past?
[22:43:14] <alex_joni> Hugomatic: it will take a while to get to 2.2.2
[22:43:27] <alex_joni> the release bump was 20 minutes ago
[22:43:35] <tomp2> you're stuck in the present ;)
[22:43:44] <Hugomatic> :-)
[22:43:44] <alex_joni> (I expect it'll be at least a couple hours before the packages get uploaded, etc)
[22:43:46] <eric_U> I'm just stuck
[22:44:16] <eric_U> tomp2: have you run your yaskawa m5i20 setup?
[22:44:35] <tomp2> not yet
[22:44:54] <eric_U> I'd like to see my encoders running before I power the dacs
[22:45:46] <tomp2> i think you can, dont enable the dac, but power the amp and turn the shaft, you should see feedback w/o motor torque
[22:46:01] <eric_U> using Axis, correct?
[22:46:13] <tomp2> using halrun
[22:46:27] <eric_U> ok
[22:46:29] <tomp2> maybe axis, didnt think of that
[22:47:41] <tomp2> i'm very incremental with a new system. got one now that is huge and was at 500V netz when the customer ordered 440... i'am at limits of all trafos, so will trun on stage by stage manually
[22:47:59] <tomp2> turn
[22:51:26] <eric_U> I'm going incremental because the x axis is aimed at my head, and z is a pain if it hits the limits
[22:51:46] <eric_U> so I'm sticking to the y axis for now
[22:52:37] <tomp2> uncouple motor from axis for initial tests. you can check encoder direction and any tacho feedback without motor being 'on'
[22:52:53] <eric_U> that's a good idea :)
[22:53:08] <tomp2> you can check motor direction with motor 'on' but not connected,, you can be safe with a bit of time & effort
[22:54:01] <eric_U> but I wasn't going to enable the drives just yet anyway
[22:54:36] <eric_U> mostly because there are a large number of relays involved
[22:55:28] <eric_U> bbaIf be back after Indian food
[22:57:32] <tomp2> i'm missing tab completion in halcmd, what governs that? gnome terminal?
[22:59:55] <fenn> readline
[23:00:07] <jepler> tomp2: depends whether the right library was available at build time. did you build it yourself?
[23:00:27] <tomp2> nope, live cd a while ago, then cvs updates for emc
[23:00:52] <jepler> umm either you did build it yourself, or you don't mean cvs updates
[23:01:37] <tomp2> uhm, i mean i used cvs to get newer versions of emc, not update, but new rip installs in new directiories
[23:02:34] <jepler> if you are building emc from source you need to have the "readline" library installed.
[23:02:43] <tomp2> how to check?
[23:02:57] <alex_joni> tomp2: run configure again, and carefully read the screen
[23:03:11] <jepler> look at configure when you run it. here are the lines you would like to see: http://pastebin.com/m5497b148
[23:03:31] <jepler> debian/control.in lists the packages required to build and run emc; you are probably missing one
[23:04:15] <tomp2> thx will do ( i just uses synaptic to see i have readline 5.1-7build1)
[23:04:41] <jepler> perhaps you do not have the readline development package installed
[23:04:57] <tomp2> correct i dont
[23:05:01] <tomp2> will get thx
[23:06:33] <JymmmEMC> * JymmmEMC pokes LawrenceG
[23:11:47] <tomp2> got readline dev pkg, got configure output http://pastebin.com/dd880602, no got tab completion in gnome-terminal, got tab completion in many other apps.
[23:14:37] <alex_joni> tomp2: did you . scripts/emc-environment ?
[23:14:54] <tomp2> think so, will try again
[23:19:04] <tomp2> alex, that was it, i usually do hat, but was following the Hal Developer's Guide letter by letter, the tip-off was the message "This script is only useful on run-in-place systems." wasnt in the terminal history
[23:19:19] <tomp2> thanks
[23:23:30] <jepler> you may need to "make clean"
[23:24:15] <tomp2> jepler: it was just '. scripts/emc-environment' boner on my end
[23:24:16] <toastydeath> man, someone should make a mini-pizza feeder for the freezer, and have it so when you type in
[23:24:19] <toastydeath> "apt-get pizza"
[23:24:25] <toastydeath> it feeds a pizza into the oven
[23:25:30] <Ziegler> sounds like a great idea to me
[23:26:39] <tomp2> E: Couldn't find package pizza
[23:27:16] <toastydeath> hahah
[23:30:38] <dmess> looks like it could be a g-code for free kind of evening... name your control... we can flavour it... Heidenhein is a PITA
[23:33:06] <jepler> tomp2: which instructions did you follow "letter by letter" that led you astray?
[23:33:18] <alex_joni> jepler: he mixed rip and installed
[23:33:30] <alex_joni> the docs with the HAL tutorial refer to installed
[23:34:38] <dmess> http://imagebin.org/12110
[23:35:09] <tomp2> i used the Hal User Manual dated 11 28 2007 it sdidnt warn me to use . scripts/emc-environment in 2.1.2
[23:35:25] <dmess> http://imagebin.org/12111
[23:35:59] <tomp2> musky eats musky,,,, musky-bait
[23:36:11] <dmess> northern pike NOT a muskie
[23:36:19] <tomp2> big head
[23:36:31] <dmess> 55 lbs... 56 inches
[23:36:38] <tomp2> wah!
[23:36:58] <dmess> the 2nd one... with the hook in is 36 inches long
[23:37:11] <LawrenceG> * LawrenceG LawrenceG has slow reactions to a poke from JymmmEMC
[23:38:12] <dmess> i figur it would cost about 3200 dollars to paint and mount that fish...
[23:40:21] <tomp2> time for the 3D holographic recording of the catch & release... remember when i caught that monster pike, look in here , see how big it was!
[23:40:39] <dmess> its the painting time that KILLS on a fish with so much surface area.... but if it was feeding on 36" long bait.... no wonder its FAT... an over achiever out of the north Winnipeg river... canuck record so far as i know.. possibly world...
[23:41:35] <tomp2> if thats the class, (and it is huge ) maybe you can get museum to do it for donating the fish
[23:42:06] <dmess> 36 lbs is my largest to date.. i was a kid .. i thought i was binging home a whale....
[23:44:08] <tomp2> what do they call pike in europe? Zander something... still bigger than anything i'd seen
[23:44:12] <dmess> the next morning dad ( worked nights ) left 3 just like it in the tube for me to shower around in the AM.. i went out and lost a 50"... 3 or 4 times....
[23:44:18] <toastydeath> http://www.machinetools.com/MT/machines/index.tmpl?page=detail&ListingID=102328
[23:44:24] <toastydeath> i found what i want for christmas!
[23:45:40] <dmess> for free??
[23:45:55] <toastydeath> no
[23:46:00] <toastydeath> but i don't have any place to put it
[23:46:02] <toastydeath> so it doesn't matter
[23:46:08] <dmess> just shipping??
[23:46:10] <toastydeath> could cost 67,000
[23:46:18] <toastydeath> but in reality it probably costs around 2500-3000
[23:46:22] <dmess> could??
[23:46:46] <dmess> not a big install??? shipping???
[23:46:52] <toastydeath> not a big install at all
[23:47:01] <toastydeath> machine weight is about 7000
[23:47:10] <toastydeath> any rigger with a truck can move that
[23:47:15] <dmess> why 67,000
[23:47:16] <toastydeath> i could probably rent a wrecker
[23:47:35] <toastydeath> i was making a joke, the price isn't listed
[23:47:52] <dmess> id slap ya...
[23:47:56] <fenn> what's special about this lathe?
[23:48:02] <toastydeath> fenn: it's a great, great lathe
[23:48:18] <toastydeath> American was one of the very best lathe manufacturers
[23:48:28] <toastydeath> that's like a 20 hp machine
[23:48:34] <toastydeath> 15-20
[23:48:53] <toastydeath> accurate, too.
[23:49:13] <dmess> we couldnt use a machine like that effectively in CANADA due to new reg's
[23:49:19] <toastydeath> why not?
[23:49:44] <dmess> ive run one of them.. the are slick
[23:49:54] <toastydeath> what law got passed in canada
[23:50:00] <toastydeath> no guards?
[23:50:17] <dmess> manual machines... no guards.. etc.. etc..
[23:50:23] <toastydeath> yeah that's crappy
[23:50:39] <dmess> lockouts... manual chucks.. yadyad...
[23:51:05] <toastydeath> and a lot of the American lathes come with tracers
[23:51:11] <toastydeath> which makes them even cooler
[23:51:15] <toastydeath> rear toolpost tracers
[23:51:31] <fenn> yea you can almost pretend you've got a cnc lathe
[23:52:05] <toastydeath> and the CNC can almost pretend it's got the torque of that manual machine!
[23:52:16] <dmess> we now HAVE CAGES around a few LARGE gap-bed lathes... where a simple chip pull.. and carry on... now is a 45 minute reset and leave a mark on the part..
[23:52:53] <toastydeath> damn
[23:53:32] <dmess> we have SCRAPED 65000 US components due to this in the past..
[23:54:11] <dmess> f18 flower pots
[23:54:17] <toastydeath> that's some shitty nonsense man
[23:54:38] <dmess> or carrot pots as i like to use em for
[23:54:56] <dmess> no nonsense...
[23:54:56] <toastydeath> if we have a nest building up we just open the damn door and pull it out with a hook
[23:57:13] <dmess> we used too.. for the last 20 yrs... but last spring someone in ENGLAND at a sister plant WRAPPED up baddly... and the company sent out a directive.... NO... touching anything rotating...
[23:57:36] <toastydeath> that sucks
[23:57:59] <toastydeath> there have been many rat's nests that i've decided "hey, that's a bit tough looking, I won't be touching that"
[23:58:03] <toastydeath> but on a finish cut?
[23:58:13] <toastydeath> whatever.
[23:58:18] <dmess> ive designed dynafile tool post holders and its been a nightmare....
[23:59:05] <toastydeath> ?
[23:59:19] <dmess> even to simple break an edge with paper...
[23:59:27] <dmess> they cant
[23:59:46] <toastydeath> so now you have to use toolholders for SANDPAPER?
