[00:03:43] <JymmmEMC> alex_joni: Enjoy!
[00:49:11] <AzRockCrawler> Any HAL gurus about?
[00:50:36] <tom1> ´╗┐if any of the emc crew from galesburg wanna see Johnny Olson, a Khaen player, he's at Wat Lao Buddharam in hampshire illinois tonight. i'm running in from detroit to see him.
[00:56:47] <AzRockCrawler> I am getting this error during load of EMC2: test2.hal:134: pin 'spindle-phase-A' does not exist
[00:57:09] <AzRockCrawler> BUT...here is line 133: newsig spindle-phase-A bit
[00:57:19] <AzRockCrawler> this is 134: net spindle-phase-A => encoder.0.phase-A
[00:57:41] <AzRockCrawler> So, I can't tell why halcmd is complaining...anyone have clues?
[01:57:25] <renesis> guys, guys
[01:57:40] <renesis> wtf do i do with like 1/2" of sawdust in an electronics cab?
[01:58:02] <renesis> most of it is maybe 18" from the electronics racks
[01:58:15] <renesis> boss was like, compressed air it
[01:58:48] <renesis> im like, yeah great blow the dust into the equipment
[01:59:01] <renesis> but they have a shopvac
[01:59:31] <renesis> theres no way a shopvac at that range will ESD the controller circuits, yeah?
[02:00:44] <renesis> i guess i could dustpan it out
[02:01:04] <skunkworks> any time you move air - there is a posibillity of esd
[02:01:17] <renesis> yeah thats why i dont wanna blow the dust off the gear
[02:01:43] <renesis> its mostly ok, the cab was open a crack and a bunch fell into the edge opposite the electronics
[02:02:12] <renesis> was like that when i got there, i found the key and locked it so it shouldnt get worse
[02:03:30] <renesis> hmm, ill scoop it out with a dustpan i guess and just lock it
[02:06:30] <AzRockCrawler> Use a big low inductance ground strap from the board (anywhere) to honest to goodness EARTH ground, and have at it with the shop vac.
[02:08:45] <AzRockCrawler> I think there is just as much potential for ESD brushing something against something else. Friction can create change in potential.
[02:09:00] <AzRockCrawler> * AzRockCrawler shrugs
[02:09:06] <AzRockCrawler> maybe
[02:09:09] <AzRockCrawler> :D
[02:16:24] <renesis> a resistor between a cmos and that ground strap is enough to blow it out
[03:58:08] <chr0n1c> yo cnc'ers!
[03:59:41] <renesis> hai
[03:59:52] <JymmmEMC> None here, try [middle of nowhere in some barn]
[04:00:40] <renesis> this chan is actually about open Command and Conquer platform development
[04:00:45] <renesis> okay no rly
[04:00:50] <renesis> i dunno what this chan is about
[04:01:12] <JymmmEMC> http://www.emc.com/utilities/globalsiteselect.jhtml?checked=true
[04:23:36] <chr0n1c> http://www.ohiopctech.com/cpg/thumbnails.php?album=11 <- the circuit board milled for my function generator project (awesome huge pics if you click to zoom in)
[04:59:27] <fenn> AzRockCrawler: spindle-phase-A is a signal, not a pin
[05:00:08] <fenn> net needs two pins to connect together, and a name for the connection
[05:00:14] <fenn> you only gave it one pin
[05:00:34] <fenn> er, i think
[05:05:48] <fenn> hm. works here. dunno what's wrong with yours. maybe put the hal files up on pastebin.ca?
[05:59:49] <chr0n1c> ok.. if anyone is still awake out there... can i still use the paralell port for different things when i don't have my machine plugged in? i read that emc changes something with the port but i can't find it now..
[06:07:57] <chr0n1c> "cat /proc/ioports" returns no parallel port?
[06:08:05] <chr0n1c> :|
[06:15:17] <AzRockCrawler> sri fenn, was away
[06:15:23] <AzRockCrawler> Yes, figured that all out -- thanks.
[06:15:27] <AzRockCrawler> Works too BTW.
[06:16:23] <micges> chr0ni1c: what "lsmod | grep "par" " say ?
[06:16:51] <AzRockCrawler> problem was me. Did not account for the opto-isolated ground on the input side. Made grounds common, got sig to PC, and EMC picked up the counts easily.
[06:17:34] <micges> chr0n1c: what "lsmod | grep "par" " say ?
[06:19:11] <chr0n1c> parport 44428 2 ppdev,lp
[06:19:14] <chr0n1c> hmmm...
[06:19:21] <chr0n1c> so one of those is my lpt1?
[06:20:37] <micges> don't know
[06:21:02] <micges> but ppdev could be
[06:21:25] <micges> what number of lpt do you have ?
[06:21:28] <chr0n1c> lol, i used to be a dos/win expert...
[06:21:36] <chr0n1c> i know it's set @ 0x378
[06:21:39] <chr0n1c> in bios
[06:22:01] <chr0n1c> and it works in win for this lcd...
[06:22:10] <chr0n1c> i know it works, i just can't find it!
[06:22:12] <chr0n1c> :D
[06:22:52] <micges> do you have lpt on addon card ?
[06:23:04] <chr0n1c> linux is way more laid out and expansive than win as far as options and ways to do things.. i get lost
[06:23:12] <chr0n1c> it's the built in motherboard
[06:23:36] <chr0n1c> built into the mobo lpt port
[06:24:18] <chr0n1c> * chr0n1c googles
[06:28:06] <chr0n1c> ppdev?
[06:28:16] <chr0n1c> * chr0n1c tries that
[06:38:24] <chr0n1c> :)0
[13:03:01] <BigJohnT> anyone ever made an air dryer from an air conditioner coil and fan?
[13:04:27] <fenn> for an air compressor?
[13:04:42] <BigJohnT> yes
[13:05:09] <fenn> no but it sounds like a 'fun' project :)
[13:05:29] <BigJohnT> I've seen a few examples where guys used an oil cooler then the thought came to me why not use an air conditioner coil and fan
[13:05:56] <fenn> how would you seal around the coils at 90 psi?
[13:06:11] <fenn> i'm picturing some kind of welded box
[13:06:28] <BigJohnT> silver solder just like when you do ac tubing
[13:06:48] <BigJohnT> run the air through the inside of the coils
[13:07:29] <fenn> oh, just solder another tube parallel to the tubing?
[13:07:58] <BigJohnT> no, use a scrap coil and fan from a broken ac unit
[13:08:07] <fenn> is this air that's under pressure or ambient pressure?
[13:08:17] <BigJohnT> under pressure
[13:08:32] <fenn> then how do you contain it?
[13:08:46] <BigJohnT> instead of freon going through the coil my compressed air will before it gets to the tank
[13:08:56] <fenn> then what cools the tubing?
[13:09:15] <BigJohnT> the small fan that came with the ac unit
[13:09:39] <fenn> is there any freon in the system at all?
[13:09:57] <BigJohnT> no, just using the condenser coil
[13:10:15] <fenn> so this is more like an intercooler than a proper refrigeration dryer
[13:10:24] <BigJohnT> yes exactly
[13:10:27] <fenn> ok
[13:11:14] <BigJohnT> however you now have me thinking about using a working window unit as a refrigeration dryer...
[13:11:44] <fenn> i think you'd have to cycle it like an automatic defrost freezer
[13:11:57] <fenn> but it would pull in a lot more water than a freezer
[13:12:31] <BigJohnT> you have to have an auto dump valve for the condensate tank
[13:13:41] <BigJohnT> cause old farts like me can't remember to dump it
[13:13:48] <fenn> oil coolers have bigger pipes than air conditioner coils
[13:14:27] <fenn> oh nevermind, i'm thinking of the condenser coil
[13:14:45] <fenn> * fenn looks
[19:20:32] <dmess> hi all
[20:35:38] <kcbanner> hey all
[20:35:55] <kcbanner> I know this might be offtopic, but I'm looking for open-source plans for a simple PCB milling machine
[20:37:11] <anonimasu> whois kcbanner
[20:37:24] <anonimasu> I've seen you somewhere else :P
[20:37:56] <kcbanner> anonimasu, me too
[20:37:59] <kcbanner> hmm
[20:38:21] <kcbanner> anonimasu, I frequent #archlinux, #ruby, #avr, #electronics...
[20:41:04] <anonimasu> sorry I dont know of any opensource plans
