[00:12:03] <Thadius> anyone awake?
[00:12:16] <Thadius> or at least zombie'esque?
[00:13:10] <Jymmm> Rrrrrrrrrrrrrrrrrrrrhjjshhggggggggggggh
[00:13:42] <Thadius> when i configured and set home for each axix at 0.0 when linuxcnc asks me to home, what essentially is it asking for? that i verify all positions are at my set home locations?
[00:14:26] <Jymmm> do you have homing switches?
[00:15:26] <Thadius> i do not
[00:15:45] <Thadius> plan to install limit switches, but entirely different
[00:15:46] <Thadius> no?
[00:15:57] <Jymmm> correct
[00:16:17] <Jymmm> thought some wire them so the server both purposes
[00:16:44] <Jymmm> Realize that 0.0 is not necessarily the HOME position.
[00:17:00] <Jymmm> it could be a relative one, not absolute.
[00:17:14] <Jymmm> It could be an offset of something else.
[00:17:17] <Thadius> well in my config for "home location" thats what I put in for each axis.
[00:17:50] <Thadius> so when its asking me to "home" what essentially does it want? is it related to machines with homing switches only?
[00:18:07] <Jymmm> what is asking you to home?
[00:18:34] <Thadius> before starting a project in linuxcnc, it says you must home before starting
[00:19:28] <Jymmm> Right, so you move your axis to a starting position, or HOME.
[00:19:38] <Jymmm> axises (plural)
[00:19:42] <Jymmm> bbl
[00:19:46] <Thadius> ok, thanks
[00:24:54] <djdelorie> Thadius: Homing just tells linuxCNC where the axis is *physically* relative to the physical limits of its motion
[00:25:29] <djdelorie> it's "go in this direction until you see this signal, then you'll be at this known position in the A..B physical range"
[00:26:12] <djdelorie> that way, linuxcnc can avoid breaking your new toy by driving it off the end
[00:27:42] <KimK_ibmlaptop> Thadius: As you plan your home switches (& limit sws, if used), the Integrator Manual homing section may be helpful: http://www.linuxcnc.org/docview/html/config/ini_homing.html
[00:28:01] <KimK_ibmlaptop> Hi djdelorie
[00:28:05] <djdelorie> hi
[00:36:40] <Tecan> hey hey
[00:36:56] <Tecan> was wondering if these no / nc switches will work for emc ?
[00:37:16] <Tecan> the fridge kind
[00:37:46] <djdelorie> for limit switches? sure
[00:37:50] <Tecan> if i click invert on pin 10 it works but the homing goes the opposite direction
[00:38:05] <Tecan> the homing is inverted too ...
[00:38:45] <djdelorie> in a default "home" operation, it goes forward until the switch is "activated", then backs off until the switch releases, then goes forward slower until activated
[00:39:17] <djdelorie> home direction is controlled by the sign of the "homing speed" value
[00:49:19] <Tecan> worked like a charm
[00:49:46] <Tecan> whats with the home switch direction ? theres same and opposite
[00:50:10] <djdelorie> same is as I described above; opposite just backs off until the switch releases
[00:50:38] <Tecan> aha :)
[00:50:40] <djdelorie> most switches have a "hysteresis" so the close and open positions are not the same; that option decides which position is "home"
[00:51:48] <djdelorie> also, one edge might be more reliable. In my system, the debounce software means that only closures are predictably located
[01:04:28] <KimK_ibmlaptop> Tecan, meet Thadius. Thadius, meet Tecan. You guys are working on the same thing, it appears.
[02:14:15] <DJ9DJ> moin
[02:15:56] <Tecan> :)
[02:17:50] <Tecan> the last thing to do is setup pwm for ma laser
[02:18:06] <DJ9DJ> hi all, happy easter ;)
[02:18:19] <Jymmm> DJ9DJ: Happy Easter!
[02:18:29] <DJ9DJ> tnx :)
[02:20:13] <Jymmm> anyone do any sheetmeatal work?
[02:26:46] <alex4nder> hey
[02:33:02] <archivist> I do sheet metal not sheetmeatal http://www.collection.archivist.info/archive/DJCPD/PD/2010/2010_07_27_tinware/
[02:40:08] <Loetmichel> mornin'
[02:45:14] <Jymmm> archivist: Aluminum and by hand, is there some simple method of joining two ends into a ring temporarily?
[02:45:50] <Jymmm> aluminum flashing to be specific.
[02:45:55] <archivist> make a clamp
[02:46:22] <Jymmm> This needs to be self contained
[02:50:31] <Loetmichel> archivist: did you solder that?
[02:50:41] <archivist> Loetmichel, yes
[02:50:46] <Loetmichel> tin or silver?
[02:51:19] <archivist> normal 60 40 electronics solder
[02:51:33] <Loetmichel> tin/lead (electronics solder) or silver solder ?
[02:51:46] <Loetmichel> ah, and its sturdy enoufh?
[02:51:49] <Loetmichel> enough
[02:52:14] <archivist> for models yes
[02:52:21] <Loetmichel> 7 have made a outrigger for a big hexaCopter
[02:52:42] <archivist> the boiler is not intended to be a working boiler
[02:53:06] <Loetmichel> but in 6040 it wasnt sturdy enough, wil do it again as soon as i have some means of holding the parts that can withstand 900°c with silver solder...
[02:53:21] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=8946
[02:53:28] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=8926
[02:53:35] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=8902
[02:54:31] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=8929
[02:55:10] <Loetmichel> maximilian_h: hihi, my exexex-girlfriend was also called bonsai ;-)
[02:56:23] <Jymmm> Loetmichel: So your XXX girlfriend?
[02:56:37] <Loetmichel> Jymmm: harhar
[02:56:46] <archivist> just seen some interesting metal bending on http://www.billcarterwoodworkingplanemaker.co.uk/12.html
[02:56:52] <Jymmm> Loetmichel: Say it out loud "Triple X"
[02:56:59] <Loetmichel> lets say: a looooong time ago ;-)
[02:57:36] <Jymmm> Loetmichel: so your really old XXX girlfriend
[02:58:43] <Jymmm> Loetmichel: (you kinda fell into that, I was just helping you along =)
[02:59:32] <Loetmichel> Jymmm: [gnicker]
[03:00:53] <mazafaka> Herculesses of EMC are on a sugar topic today, khe-khe-khe
[03:01:17] <Jymmm> archivist: I'm trying to come up with a pot stand/wind break/trangia burner stand that can fit into the cooking pot
[03:01:18] <Loetmichel> archivist: that wood planes look like MUCH work
[03:01:47] <Loetmichel> whats tragina?
[03:02:00] <Jymmm> Loetmichel: alcohol stove
[03:02:10] <Loetmichel> and if there is a burner involved: better use brass solder or weld the parts ;-)
[03:02:25] <Loetmichel> ah, like the ones made of soda cans?
[03:02:47] <Jymmm> not the same, http://patentpending.blogs.com/photos/uncategorized/capture06142005124727_pm.jpg
[03:03:03] <Loetmichel> ah, but similar
[03:03:12] <Loetmichel> oh, german writing on the lid?
[03:03:12] <archivist> and not aluminium as it melts
[03:03:13] <Jymmm> No, different.
[03:03:23] <Jymmm> Loetmichel: swiss
[03:03:29] <Jymmm> .SE
[03:03:29] <Loetmichel> i see
[03:03:55] <Jymmm> It can also be snuffed out to conserve fuel
[03:04:04] <archivist> rivet your joints
[03:04:06] <Jymmm> and you can store 3ox inside it.
[03:04:20] <Loetmichel> Jymmm: i've seen this one with the center reccess made of sodacans on youtube also
[03:04:21] <Jymmm> archivist: it has to roll up and be stored in the cook pot
[03:04:33] <Loetmichel> just without the screw-on-lid ;-)
[03:04:49] <Jymmm> Loetmichel: Yes, there are LOTS of beer can stoves of various designs, they are different.
[03:04:56] <archivist> you dont roll up metal
[03:05:44] <Loetmichel> archivist: oh, i can think of a pot sand made of 0,2mm stainless that could be rolled up...
[03:05:49] <archivist> unless its withing its elastic limit, ie a spring
[03:06:01] <Loetmichel> or stored flat and rolled up to do its job
[03:06:17] <Loetmichel> s/sand/stand
[03:07:15] <Jymmm> click on video http://www.traildesigns.com/stoves/caldera-cone-system
[03:08:48] <Loetmichel> yeah, thats the way i thougt of
[03:09:34] <Jymmm> Loetmichel: What I'm TRYING to tell you, is yes they sorta kinda "look" the same, but they are all different.
[03:10:08] <Jymmm> vise grips, channel locks, needle nose are all "pliers", but they are not the same.
[03:11:14] <Loetmichel> if i understand it right the burner in your picture works by heating up the rim with its flame, thereby heating the center reccess which in course heats up and vaporizes the fuel
[03:11:38] <Loetmichel> so the soda can burners work on the same principle as the one you showed, thats what i meant
[03:12:06] <Jymmm> Again, they are not the same. There are even big differences on the soda can stoves.
[03:12:18] <Loetmichel> yes, i've seen
[03:12:41] <Loetmichel> i dont want to annoy you so lets say you are right ;-)
[03:13:09] <Jymmm> *sigh*
[03:13:36] <Loetmichel> ;-)
[03:14:40] <Loetmichel> dont take me TOO seriously, i dont do myself ;-)
[03:15:14] <Jymmm> Loetmichel: Well, you were trying to simplify it a little too much is all.
[03:16:16] <Jymmm> Having made three different soda can stove designs, they are NOT all the same.
[03:16:57] <Jymmm> I wouldn't want someone to think that they are all the same, get/make one and be disappointed.
[03:18:45] <Jymmm> Oh, and for the record.... When they say that burning wax is non-toxic, they lie and can kiss my ass!
[03:51:27] * archivist wonders if rob_h knows a uk supplier of 2" dia cup grinding wheels
[03:51:50] <rob_h> cromwelltools?
[03:53:04] <archivist> they only seem to list a 100mm dia one
[03:53:29] <rob_h> if stuck they might source one for you, 1-2days probly.
[03:55:13] <archivist> I could drop into the Derby branch and wind up the counter intelligence :)
[03:55:37] <archivist> for a little tool post grinder I found
[03:56:22] <Loetmichel> [10:09] <Jymmm> Oh, and for the record.... When they say that burning wax is non-toxic, they lie and can kiss my ass! <- depends on what burning wax is
[03:56:23] <rob_h> yea seems a small size to find
[03:57:44] <Loetmichel> real bee wax / stearine / paraffine IS non-toxic
[03:57:57] <Loetmichel> the alcohol gels: i dont know.
[03:58:25] <Loetmichel> esbit (c) is definetly not really good to the health if ingested
[03:58:29] <archivist> rob_h, fount a taper cup http://www.midlandabrasives.com/cat_name/taper-cup-wheels.aspx
[03:59:13] <Loetmichel> hmmm, i think i could use a 60mm cup diamond wheel
[03:59:44] <Loetmichel> the dremel cutting disks i use to grind my engraving bits are a bit coarse
[04:00:25] <archivist> or get from america http://www.artcotools.com/dumore-grinding-wheels-recessed-wheels-c-811-p-1-pr-18334.html
[04:01:00] <archivist> 774-0034 is the part that fits
[04:01:20] <archivist> oops I mean 774-0053
[04:01:36] <rob_h> http://www.abtec4abrasives.com/grinding-wheels-40mm-1-12-up-to-80mm-3-diameter-276-c.asp
[04:02:43] <archivist> nice find rob_h :)
[04:03:05] <rob_h> not sure where else can look right now
[04:04:28] <rob_h> wunder if any one else in here in UK is going to the mach2012 show at NEC
[04:05:13] <archivist> wen is it
[04:05:21] <rob_h> 16 - 20
[04:05:32] <rob_h> this month
[04:07:35] <rob_h> problt take you all week to walk around it now its so big
[04:07:56] <rob_h> www.machexhibition.com
[04:11:06] <archivist> I just registered :)
[04:11:42] <rob_h> think we looking at tuesday or wed not sure yet depends what happens here
[04:12:07] <rob_h> want to look around drives and controls also
[04:12:37] <archivist> I hate seeing how much money I would like to spend :)
[04:12:50] <rob_h> erm yes
[04:13:21] <archivist> I know my hands will hurt from the weight of leaflets
[04:14:51] <archivist> hmm time to go out to play steam engines
[04:15:00] <rob_h> sounds good
[04:15:26] <archivist> http://www.middleton-leawood.org.uk/leawood/
[04:16:20] <rob_h> aah big one
[04:24:50] <archivist> yup, have to be there for 12 as we left the beam blocked up over winter
[04:30:39] <DJ9DJ> re
[07:08:01] <joe9> is there a vim syntax plugin for gcode? if there is, what is the file extension that it recognizes automatically?
[07:13:24] <Jymmm> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?action=browse&diff=1&id=Highlighting_In_Vim
[07:20:36] <joe9> Jymmm: thanks.
[07:20:46] <Jymmm> np
[07:33:19] <jthornton> what's the best/easy way to backup all my machines on my mixed Ubuntu/Winblows LAN to one or two places?
[07:33:34] <Jymmm> rsync
[07:33:43] <jthornton> thanks
[07:38:36] <Jymmm> jthornton: Also, consider rdiff-backup if you want incremental backups too http://www.nongnu.org/rdiff-backup/
[07:43:24] <Jymmm> jthornton: There's also http://www.bacula.org/en/
[07:44:48] <jthornton> thanks reading them now
[07:46:18] <Jymmm> jthornton: The simplest is rsync, as it just works. But if you delete/change a file and go to retrieve the original three months ago, you'll only have the latest version.
[07:47:06] <Jymmm> Speculating that you've seting rsync on a daily/weekly basis that is.
[07:47:24] <jthornton> at least the latest version would normally be ok I guess
[07:47:44] <Jymmm> Yeah, something is better than nothing at all.
[07:48:36] <Jymmm> rdiff-backup is the alternative, then you CAN have that 3 moth old original, and the current revissed file
[07:48:56] <jthornton> mainly I'm interested in backing up my configs and subroutines automagicly
[07:49:48] <joe9> i use rsync for backing up the full machine. I am thinking about using a git repo for the backup.
[07:50:32] <joe9> jthornton: rsync and check out the exclude file. it can contain all the dirs/files that you do not want backed up.
[07:50:57] <jthornton> reading this now http://everythinglinux.org/rsync/
[07:51:08] <joe9> jthornton: if it is configs, then git is not a bad idea too. for my configs, i git the directory.
[07:51:23] <joe9> and, then rsync the root filesystem to a storage location
[07:51:28] <joe9> that is what I have now.
[07:51:46] <joe9> I am thinking of putting the root filesystem on git. not sure if that is a good idea though.
[07:52:33] <Jymmm> jthornton: Since rsync can use ssh, you don't need a "server" or daemon. A cron job as simple as rsync -r source destination would work.
[07:52:44] <joe9> too much duplication as I already git the important directories and files anyway.
[07:53:29] <jthornton> Jymmm, what is the syntax for the source over the lan?
[07:53:36] <Jymmm> the same
[07:54:32] <joe9> the "CNC Programming Handbook" by Peter Smid is a pretty extensive book.
[07:55:06] <joe9> it seems like a bible. anyone read it?
[07:55:09] <jthornton> say I have a computer named Plasma with an EMC2 directory what would the syntax be for that?
[07:55:30] <asdfasd> anyone good in HAL ?
[07:55:40] <jthornton> just ask the question
[07:55:58] <joe9> jthornton: there are some good examples online. i doubt it is simple enough to cover it in the chat.
[07:56:19] <joe9> the basic syntax is "rsync <ssh options> source destination"
[07:56:42] <joe9> jthornton: check out the --dry-run, it is very helpful
[07:56:47] <asdfasd> I made a button with pyvcp can I run a function touch_off()
[07:57:07] <jthornton> right, I see that in this tutorial but what is the syntax for the remote source
[07:57:35] <jthornton> or do I just do a pwd after navigating over to there?
[07:58:09] <joe9> jthornton: jthornton@plasma:/home/mine/emc2-dev for source
[07:58:22] <joe9> if you are on the destination
[07:58:31] <jthornton> ok, thanks
[07:59:34] <jthornton> so username@computername:/home...
[08:00:18] <joe9> yes.
[08:00:23] <jthornton> thanks
[08:00:34] <joe9> use --dry-run though
[08:00:42] <jthornton> ok
[08:00:43] <joe9> cannot emphasize that enough.
[08:01:07] <Jymmm> jthornton: READ FIRST http://www.comentum.com/rsync.html
[08:01:31] <Jymmm> jthornton: You CAN fuck up if you screw up the syntax
[08:02:19] <jthornton> ok
[08:04:22] <Jymmm> jthornton: And it's best of you setup and use keys instead of passwords if you want to automate this.
[08:04:35] <jthornton> keys?
[08:04:43] <Jymmm> ssh keys
[08:05:05] <DJ9DJ> re
[08:05:07] <Jymmm> so it can login automagically
[08:05:13] <jthornton> ok
[08:09:28] <Jymmm> jthornton: rsync is meant to be able to do a secure backup over the internet in an efficient manner.
[08:09:52] <Jymmm> but can also backup directories, hdd's, etc
[08:11:28] <ReadError> rsync is like a smart scp
[08:11:42] <Jymmm> jthornton: For example. you can have two hdd's in a server. and you daily rsync one hdd to the other. Then you ALWAYS have a 24hour old backup no matter what.
[08:12:35] <Jymmm> jthornton: If you have a problem with the main hdd. You just swap the hdd cables and bootup and you're up and running again like you were 24hr ago.
[08:13:06] <Jymmm> Or you can mount that backup hdd and recover 24hr old file(s)
[08:22:33] <jthornton> can you list the host names on a LAN in the terminal somehow?
[08:22:43] <jthornton> local host names
[08:24:28] <joe9> jthornton: check the /etc/hosts file.
[08:26:57] <ReadError> i dont think you can list them like that though..
[08:27:02] <ReadError> you can run your own dns server
[08:27:43] <jthornton> I'm making progress "ssh: connect to host hardinge.local. port 22: Connection refused"
[08:27:44] <ReadError> i think samba does some hostname type stuff?
[08:28:14] <jthornton> better than "ssh: Could not resolve hostname hardinge: Name or service not known"
[08:28:36] <ReadError> do ping hardinge.local
[08:28:44] <ReadError> make sure it resolves to an ip
[08:28:55] <ReadError> then you can do telnet hardinge.local 22
[08:29:00] <ReadError> see if you get the banner
[08:30:05] <jthornton> telnet: could not resolve harding.local/22: Name or service not known
[08:30:11] <jthornton> ping worked
[08:30:21] <ReadError> whys it say /22?
[08:30:27] <ReadError> on linux the syntax is like
[08:30:31] <ReadError> telnet hostname port
[08:30:41] <ReadError> telnet 127.0.0.1 22
[08:30:49] <jthornton> dunno I typed telnet hardinge.local 22
[08:31:44] <jthornton> tried telnet hardinge.local. and got this telnet: Unable to connect to remote host: Connection refused
[08:31:56] <jthornton> seems to want a period after local
[08:31:57] <ReadError> this is on linux?
[08:32:07] <jthornton> ubuntu 10.04
[08:32:10] <ReadError> ah
[08:32:20] <ReadError> you using local nameserver?
[08:32:39] <jthornton> what is that?
[08:33:45] <jthornton> I just have an 8 port router and everyone plugs into that...
[08:35:08] <jthornton> maybe I need to set up ssh keys now
[08:35:34] <ReadError> well you need to establish a connection first ;)
[08:35:36] <ReadError> ide stick to ips
[08:35:41] <ReadError> worry about hostnames later
[08:37:13] <jthornton> the remote is another Ubuntu 10.04 do I need to do something there to have it not refuse the connection on 22?
[08:39:15] <ReadError> on the remote
[08:39:19] <ReadError> do lsof -i :22
[08:39:25] <ReadError> make sure its listening on *
[08:39:30] <ReadError> and check iptables
[08:39:53] <jthornton> ok, breakfast is ready so I'll do that in a bit
[08:39:54] <Valen> your trying to ssh in?
[08:40:07] <jthornton> I think so
[08:40:40] <jthornton> rsync -avz -n -e ssh john@hardinge.local.:/home/john/emc2 /home/john/test
[08:41:07] <jthornton> ssh: connect to host hardinge.local. port 22: Connection refused
[08:41:10] <Valen> what are you trying to do?
[08:41:30] <jthornton> set up a backup of all my machines to this computer
[08:41:31] <Valen> as in the end goal
[08:41:33] <Valen> ahh
[08:41:44] <Valen> got ssh installed on them all?
[08:41:49] <Valen> as in the server
[08:42:14] <Valen> (openssh-server)
[08:42:21] <Valen> you should then be able to ssh to the server
[08:42:22] <jthornton> that I don't know
[08:42:27] <Valen> its not by default
[08:42:30] <Valen> you need to install it
[08:42:35] <jthornton> then no
[08:42:51] <Valen> you might need rsync server too
[08:43:00] <jthornton> so does this computer need the ssh server or the remotes
[08:43:01] <Valen> nfi though i never really use rsync

[09:00:28] <ReadError> otherwise..
[09:00:38] <ReadError> not sure if it runs in this build
[09:04:26] <joe9> sorry, for asking this again. what is the opinion on the "CNC Programming Handbook" by Peter Smid. Is it outdated or still recommended?
[09:07:47] <JT-Shop> never read it myself
[09:07:59] <JT-Shop> is it on the web?
[09:13:10] <joe9> JT-Shop: yes, ebookie.
[09:13:18] <JT-Shop> free?
[09:13:27] <joe9> is there any other book that is recommended for someone getting started with CNC stuff?
[09:13:40] <joe9> yes
[09:13:59] <JT-Shop> sorry, I graduated from the School of Hard Knocks and we didn't have a book
[09:14:11] <JT-Shop> got a link?
[09:15:04] <joe9> no, i don't. i got it a few days ago and i do not have history.
[09:19:42] <ReadError> joe9: can you share it?
[09:19:47] <ReadError> bored at work need me some readin!
[09:20:44] <Thadius> good morning all
[09:22:11] <ReadError> mornin
[09:22:15] <ReadError> you ordered the fireball?
[09:57:52] <mazafaka> JT-Shop: I today have added a flue damper (just some flat disc with holes which rotates and closes the outlet to maybe 50%) and haven't found much differences. Wood chunks probably burn for a little longer.
[09:58:47] <JT-Shop> cool
[10:02:42] <mazafaka> cool, but had to make the stove more vertical because 2-mm thick stainless steel construction has changed its size because of some huge amount of heat once
[10:05:56] <JT-Shop> I warped the insides of my Wonderwood with too hot a fire when I had no insulation in the garage... and I was cold
[10:10:15] <mazafaka> I open the door of the stove to let the heat to go to the room, it's the only way to get hot air of cold garage (-10 Celsius up to +20 Celsius)
[10:12:54] <mazafaka> I think it is right to open it only on some time, otherwise some amount of fumes will go inside, anyway. When Live coals appear, they can heat up the air of the room very quickly. I also have learned to put less amount of wood into the stove, and later add regularly.
[10:13:18] <DJ9DJ> re
[10:14:17] <mazafaka> Now need to take a rest. Dogs played with the trash bin, I gathered various plastic trash all around the apartment this morning.
[10:18:36] <DJ9DJ> hmm, is that the new way of searching easter eggs? ;)
[10:19:47] <ejang> New emc2er, check in
[10:30:29] <mazafaka> I think it's a brand new way to have a funny pastime at home for a dog ;)
[10:33:38] <JT-Shop> lol
[10:37:43] <mazafaka> the dog even goes home when I say so...

[10:39:25] <mazafaka> This aluminum sheet will be closer to the walls later, I think the stove overheats on the sides of the corner.
[10:40:38] <mazafaka> And on this photo it's seen how tricky it is to prevent the chain from touching the swingarm and frame: http://www.flickr.com/photos/ilyagalkin/6910917350/in/photostream/

[10:40:50] <psha> wrong window :]
[10:44:03] <mazafaka> psha is fan of aeon flux
[11:41:46] <joe9> there is no backlash on the X, Y or Z axis with my new taig.
[11:42:23] <joe9> i measured it with a HF dial indicator and moving 5 cm on the axis. is that a good measurement?
[11:42:33] <joe9> or, should I be considering larger distances?
[11:43:47] <Jymmm> Move in a 10cm square 4 times may be better
[11:44:59] <mazafaka> Why not 40 times then?
[11:45:42] <Jymmm> just depends on how anal one may be.
[11:51:30] <JT-Shop> sounds too good to be true... how did you measure the backlash?
[11:53:14] <alex4nder> hey
[11:53:49] <JT-Shop> all this talk makes me sleepy
[11:53:51] <alex4nder> joe9: there's always backlash.. how sure are you that your measurement tools are working and/or precise enough?
[11:54:05] * JT-Shop goes to take a nap
[11:55:17] <Jymmm> Happy Bunny Day!!!
[11:55:24] <alex4nder> yes
[11:55:32] <alex4nder> brunch in an hour.
[11:56:30] <ReadError> w00t over halfway done at work
[11:56:36] * ReadError starts his 5 hour countdown
[12:12:19] <joe9> jymmm: alex4nder: ok, thanks.
[12:12:50] <joe9> jt-shop, put the dial indicator at the end of the axis. moved the axis away by 10 cms and back to 0 (where it was)
[12:27:13] <IchGuckLive> happy Easter to all of you wherever you are
[12:27:20] <joe9> http://groups.yahoo.com/group/taigtools/message/23417?var=1&p=3 is how I measured backlash.
[12:29:16] <IchGuckLive> joe9: are your mashining parts that pricise so you need backlash into the ini
[12:29:46] <joe9> IchGuckLive: my plan is to mill pcb's.
[12:29:58] <joe9> the traces are atleast 15mils
[12:30:02] <IchGuckLive> therfor its not nessesaty
[12:30:14] <joe9> oh, ok. thanks. I did not know that.
[12:30:29] <IchGuckLive> what is your backlash
[12:30:29] <archivist> joe9, it does matter!
[12:31:08] <joe9> i cannot measure backlash with my dial indicator.
[12:31:31] <IchGuckLive> joe9: 0.002inch is good if you got this
[12:31:45] <archivist> joe9, if you have ball screws there should be no measurable backlash
[12:31:53] <joe9> the dial indicator has a granularity of 0.001 inch
[12:32:01] <archivist> IchGuckLive, 2 thou is bad
[12:32:20] <IchGuckLive> archivist: for pcb good
[12:32:41] <archivist> no not good for pcb either imo
[12:33:09] <joe9> this is what I bought https://www.a2zcorp.us/store/ProductDetailNP.asp?Cguid={4C4BECA4-849D-4CA8-ADF4-24E6A8AA98C4}&ProductID=6034&Category=Taig:Mill%20Machine
[12:33:32] <joe9> "Ball bearings in lead screw bearing block, Bronze Leadnuts,"
[12:33:53] <joe9> not sure if those ball bearings are the reason that I am not able to measure backlash.
[12:34:40] <joe9> archivist: immeasurable backlash good, I presume?
[12:34:49] <IchGuckLive> there is no backlash on this mashie
[12:34:51] <archivist> good
[12:35:30] <IchGuckLive> there is also a certificate coming with the mashine backlash messurments
[12:35:55] <joe9> IchGuckLive: i will ask for that.
[12:35:56] <joe9> thanks.
[12:36:03] <IchGuckLive> messured for eatch axis and spindle
[12:36:32] <IchGuckLive> 1K USD nice prise
[12:36:44] <joe9> i measured for the axes. but not the spindle.
[12:36:54] <joe9> X, Y and Z axes.
[12:37:12] <IchGuckLive> so gor fo non backlash in the ini
[12:37:42] <joe9> ok, thanks.
[12:37:56] <IchGuckLive> best to check is in real milling go zig zack L Form with minimal stepover
[12:38:13] <IchGuckLive> joe9: whats your cutter size
[12:38:16] <joe9> ok, thanks.
[12:38:22] <joe9> IchGuckLive: no idea, yet.
[12:39:54] <IchGuckLive> 0.0118 is good for pcb
[12:40:08] <joe9> ok, thanks.
[12:40:23] <IchGuckLive> thats 0.3mm isolation
[12:41:18] <IchGuckLive> good also for manuell resharp under magnifying glass
[12:41:59] <joe9> ok. thanks.
[12:46:13] <ssi> JT-Shop: around?
[12:51:22] <IchGuckLive> joe9: http://foengarage.de/pcb.jpg example
[12:51:49] <IchGuckLive> joe9: cheesMill with 0.5mm backlash
[12:52:38] <IchGuckLive> joe9: the drills does not fit the center of the millings
[13:19:52] <Cylly> *hrmpf* my cnc mill is NUCH to small... now i have to make the sync bar for the mill for my colleauge in the mounts...
[13:20:50] <Cylly> 'cause 450*80*8mm is a lot bigger than 200*110*110mm movement on my micro mill...
[13:20:57] <Cylly> MUCH
[13:21:08] <IchGuckLive> im off BY
[13:29:00] <Spida> how would a milled trace with backlash look like, and how without? any samplepictures?
[13:30:06] <JT-Shop> ssi, napping
[13:30:42] <archivist> Spida, cradek's without backlash http://timeguy.com/cradek/cnc/pcb
[13:31:07] <archivist> tracks between pads etc
[13:34:04] <JT-Shop> joe9, what is the accuracy of your test indicator?
[13:34:53] <Spida> archivist: how would it look like with backlash?
[13:35:55] <archivist> Spida, for cradeks board the track could be cut
[13:36:16] <archivist> all depends on amount of backlash
[13:36:42] <archivist> JT-Shop, <joe9> the dial indicator has a granularity of 0.001 inch
[13:47:22] <ReadError> what a good pendant controller?
[13:47:25] <ReadError> nothing too fancy
[13:50:15] <Loetmichel> ReadError: make one yourself?
[13:50:23] <ReadError> yea possible
[13:50:29] <Loetmichel> easiest way would be a gamepad
[13:50:39] <ReadError> i seen some for around 150
[13:50:46] <ReadError> but cant for the life of me find em again ;(
[13:50:50] <Loetmichel> a usb gamepad
[14:06:47] <JT-Shop> $20
[14:07:02] <JT-Shop> unless you want a MPG then it is more

[14:13:59] <ReadError> yea i want a wheel
[14:14:04] <ReadError> looks nice :)
[14:31:15] <ReadError> will EMC keep track of pulses generated via a MPG?
[14:40:56] <JT-Shop> what do you mean by "keep track of"?
[14:52:26] <JT-Shop> damm when I clean my glasses off the keyboard got much more dirty
[14:57:51] <Tom_itx> don't clean em
[14:58:28] <Tom_itx> sticking your head inside a cnc tends to do that
[15:01:52] <JT-Shop> I just get a face full of coolant when I open the door on the CHNC
[15:02:28] <Tom_itx> yup
[15:03:01] <Tom_itx> when i was running those bar machines it was virutally unavoidable
[15:05:19] <JT-Shop> almost got the irons done for the 6 pounder
[15:08:51] <Tom_itx> nice
[15:11:18] <ReadError> JT-Shop
[15:11:23] <ReadError> i mean keep track of the pulses
[15:11:27] <ReadError> so it knows where the tool is
[15:15:27] <JT-Shop> yes
[15:15:30] <Tom_itx> of course

[15:58:16] <asdfasd> and very quiet :)
[15:58:56] <Loetmichel> yes
[15:59:14] <asdfasd> my mill is large and not suitable for metals, but recently I milled some steel, such a horrible noise
[15:59:25] <Loetmichel> i have my workspk in the appartment
[15:59:30] <Loetmichel> loud would be bad
[15:59:40] <Loetmichel> workshop
[16:00:46] <asdfasd> I made a box around the mill, with sound insolation, much better
[16:02:04] <JT-Shop> I made a box around my BP once but it got in the way http://i47.photobucket.com/albums/f163/johnplctech/Machine%20Shop/HPIM0599.jpg
[16:02:26] <JT-Shop> for your enjoyment http://i47.photobucket.com/albums/f163/johnplctech/Machine%20Shop/HPIM0598.jpg
[16:03:59] <Spida> ouch
[16:04:16] <JT-Shop> didn't hurt anything but my feelings
[16:04:36] <Spida> and the tool.
[16:05:01] <asdfasd> I just struggled with mach3 for lathe and tool changes, there is something wrong when you change front and rear post tools, wrong calculations for offsets, how about EMC2? anyone changing tools with front and rear posts?
[16:05:11] <JT-Shop> yea, it did pretty good for about 3/8" but couldn't stand the presssure at 200IPM
[16:05:24] <JT-Shop> rob_h, does
[16:05:51] <JT-Shop> my CHNC is front only, rob_h has a superslant with both front and rear
[16:06:20] <JT-Shop> if he is about I've pinged him enough to get his attention for sure :-)
[16:07:02] <JT-Shop> trunnion irons done... now for some simple axle straps
[16:07:34] <Loetmichel> JT-Shop: OUCH!
[16:07:35] <asdfasd> I changed from mach3 to EMC on my mill, if I change on the lathe too, then I will fotgot about mach3...
[16:08:03] <djdelorie> JT-Shop: and you wonder why I keep asking about feed rates and chip loads :-)
[16:08:49] <Loetmichel> JT-Shop: did the same with a 3mm TC bit... but deeper and with 24kRPM
[16:08:58] <Loetmichel> ... and a machine with weak steppers.
[16:09:22] <Loetmichel> result: a tungsten mill bit welded to the vice ;-)
[16:10:20] <Loetmichel> was white hot in seconds and as i hit the emergency and the spindle stopped it was welded to the side of the vice ;-)
[16:10:32] <asdfasd> djdelorie: I never broke a tool because of wrong feed, but wrong coordinates and G0 .... and gone...
[16:10:56] <djdelorie> I broke two yesterday, but I was "testing the limits" so kinda expected to break them eventually
[16:11:34] <asdfasd> better keep the manufacturers recommentations
[16:11:48] <asdfasd> specialy on steel
[16:12:08] <djdelorie> resharpened pcb drills in fr4
[16:12:28] <asdfasd> on wood, plastic and other soft materials I use 4X recomended RPM and feed, and working perfect
[16:12:30] <djdelorie> mostly, though, it was the limits of how fast my machine can move before the shaking messes up the drill
[16:12:35] <JT-Shop> asdfasd, that is what happend to the vise in that photo G0 and X- something
[16:13:51] <asdfasd> yeah I guessed, because the broken surface looks like mine :)
[16:15:36] <asdfasd> sharp tools dont brake while cutting, only when somebody did something wrong, too bad if there is nobody to blame :)
[16:16:07] <djdelorie> if the XY changes while you're drilling, it's easy to snap an 0.0145" drill bit
[16:16:48] <Loetmichel> hrhr
[16:16:48] <asdfasd> if XY changes definitely have to blame somebody :)
[16:16:50] <djdelorie> and my carriage wobbles in XY if the Z feed is too fast
[16:17:00] <Loetmichel> the smallest i possess are 0,3mm
[16:17:01] <djdelorie> I blame nature for making weak trees :-)
[16:17:32] <djdelorie> 0145 is about 0.37mm

[16:18:03] <Loetmichel> and 0,4mm two flute mill bits (left) ;-)
[16:18:09] <asdfasd> my dad always say for the wooden CNC - beware with the woodworms :D
[16:18:48] <djdelorie> I have a tool called a "woodworm" but it's a screw chuck for a wood lathe
[16:19:25] <Loetmichel> my old mill was made from wood also
[16:20:04] <Loetmichel> ... more or less, it was "siebdruckplatte", plywood 20 sheets or so glued with melamine instad of white glue
[16:20:23] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=4935
[16:20:27] <asdfasd> first test on my mill was with dremel not very good, now I have good spindle but I didnt make any PCBs I can find a video with drilling
[16:21:05] <djdelorie> I use a dremel in a drill press for hand-drilling, but the runout on a dremel is pretty high
[16:21:14] <djdelorie> the cnc machine has a 56k rpm air spindle in it

[16:33:02] <Tecan> how many micro bits u break ?
[16:34:23] <asdfasd> none, actually I made only 2 PCB with the dremel, that was 4 years ago, since then no time for any electronics
[16:34:54] <Tecan> u need a pick an place machine :)
[16:35:54] <asdfasd> I need to win the lottery, then I can pick and place by hand, and slowly I will enjoy my hobby, but now... too busy
[16:37:57] <asdfasd> where I can attach a photo?
[16:38:54] <ReadError> just got a new dremel
[16:39:58] <DJ9DJ> gn8
[16:40:39] <Loetmichel> asdfasd: anny ad-free pickhoster and the link here
[16:40:48] <Loetmichel> any
[16:41:09] <asdfasd> I dont know any
[16:42:08] <asdfasd> somebody told me before a site where you upload an image and they give you a temporary link
[16:42:36] <ReadError> imgur.com
[16:42:42] <ReadError> best out
[16:43:04] <Tom_itx> imagebin
[16:43:09] <asdfasd> I found it imagebin
[16:43:37] <asdfasd> this is the second PCB, no video, only photo http://imagebin.org/207236
[16:44:22] <ReadError> why are the holes so far off?
[16:45:14] <asdfasd> no idea, probably bad fixing
[16:45:24] <asdfasd> they are all moved one way little bit
[16:46:56] <Jymmm> JT-Shop: jthornton ping
[16:47:25] <Jymmm> JT-Shop: jthornton
[16:47:57] <Jymmm> JT-Shop: jthornton Have you ever heard of "thermos cooking" before? It's kinda interesting. I tried a couple of things out and not too shabby.
[16:49:59] <Loetmichel> asdfasd: looks like a bnit to wide engraving bit
[16:50:12] <Loetmichel> my last milled pcb:
[16:50:28] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=804
[16:50:42] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=814 (chemically tinned)
[16:50:54] <Jymmm> that's icky! should I look at the photo now?
[16:51:00] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=819 <- other side
[16:51:16] <asdfasd> the bit was fine, but I made wrong settings on the G code generator, it made several passes
[16:51:32] <Jymmm> Loetmichel: looks nice!
[16:52:02] <Loetmichel> the parts pront ist printed mirrored on paper with a leser printer
[16:52:04] <Loetmichel> laser
[16:52:08] <Loetmichel> and then ironed on
[16:53:37] <asdfasd> Jymmm: "thermos cooking" sounds like "student toaster" 1 iron upside-down and you toast your sandwitch on it :)
[16:54:15] <Jymmm> asdfasd: I was able to COOL dried blackeyed peas in the thermos just using boiling water
[16:54:20] <Jymmm> err COOK
[16:54:44] <djdelorie> Loetmichel: toner will stick to the fr4 better if you sand it with 400 grit first; toner doesn't like sticking to smooth surfaces
[16:55:09] <Jymmm> asdfasd: it took 10+ hours, but I didn't have todo anything at all.
[16:55:45] <Loetmichel> djdelorie: tahts ok, fir the parts placement print some missing toner isnt really a drama
[16:56:08] <asdfasd> :)))))) yeah that remind me for my student life, a lots of time and limited posibilites, then people became really inventive :)
[16:56:27] <djdelorie> I know, just mentioning it. Also, knowing that, you learn why you can use transparencies for toner transfer - they're very smooth :-)
[16:56:31] <Jymmm> asdfasd: I tried 1 cup of brown rice at noon, checked it a few minutes ago, and needs maybe another 2hours or so.
[16:57:04] <Jymmm> asdfasd: Well, it's when you have limited fuel, etc
[16:57:35] <Jymmm> asdfasd: But the ease of it if you just plan ahead, seems to work really well.
[16:57:51] <alex4nder> hey
[16:58:31] <Jymmm> asdfasd: or if you go hunting, backpacking, hiking, etc and want a hot meal when you're done.
[16:58:49] <asdfasd> Jymmm: where are you from?
[16:58:57] <Jymmm> asdfasd: California
[16:59:02] * Tecan plugs in planet of the apes while setting up laser
[16:59:10] <asdfasd> Im from bulgaria
[16:59:16] <Jymmm> asdfasd: ah
[16:59:45] <asdfasd> now living in london, but still remember for my country, people really look ahead because of no money
[17:00:22] <Jymmm> asdfasd: Ah, yeah... just need boiing water and 8+ hours, plus a good thermos or two.
[17:00:52] <Jymmm> asdfasd: I SUCK at cooking rice without a rice cooker, and beans, oh hell, they take forever on the stove.
[17:01:14] <Jymmm> asdfasd: I'm going to try pinto beans next and see what happens.
[17:01:19] <alex4nder> haha
[17:01:19] <alex4nder> beans
[17:01:21] <alex4nder> come on man
[17:01:41] <Jymmm> alex4nder: They are the most difficult things to cook is why I used them as a test.
[17:02:09] <alex4nder> why?
[17:02:32] <Jymmm> alex4nder: Dreid beans take FOREVER to rehydrate, and then cook.
[17:02:35] <Jymmm> Dried
[17:02:43] <alex4nder> you put them in water in the fridge, wait a day or two, and cook
[17:02:51] <alex4nder> they're autopilot food
[17:02:54] <Jymmm> alex4nder: And they ferment
[17:03:14] <asdfasd> Jymmm I guess your next hollyday will be on the moon :)
[17:03:14] <alex4nder> only if you leave them above temperature
[17:03:16] <Jymmm> alex4nder: and what if you dont have a frig?
[17:03:22] <alex4nder> Jymmm: you dig a hole
[17:03:30] <alex4nder> like when you're camping
[17:03:32] <Jymmm> alex4nder: if you're hiking?
[17:03:44] * alex4nder shrugs.
[17:03:45] <Jymmm> like 5 mile hike
[17:03:48] <alex4nder> I've cooked lobster while camping.
[17:03:58] <alex4nder> carrying those fuckers on your back for 7 hours
[17:04:08] <Jymmm> lol
[17:04:52] <alex4nder> Jymmm: my dad was telling me that when he was a teenager, they used to hike into the canadian outback, and cook pies and shit on the fire.
[17:05:05] <Loetmichel> [23:53] <Jymmm> alex4nder: And they ferment <- hrhrh, in germany we say "jedes boehnchen gibt sein toenchen" ("every bean gives a sound") ;-)
[17:05:11] <Jymmm> alex4nder: Yeah,I've seen that done a LOT using dutch ovens.
[17:05:16] <alex4nder> Loetmichel: haha, that's a different problem.
[17:05:45] <Jymmm> Loetmichel: Beans, beans, the musical fruit. The more you eat, the more you toot!
[17:06:03] <Loetmichel> Jymmm: like that `, yeah
[17:06:20] <alex4nder> speaking of fermenting
[17:06:44] <alex4nder> I need to start some sauerkraut today
[17:06:50] <Loetmichel> alex4nder yes, a beer to the serrano ham hre would be nice ;-)
[17:07:23] <Loetmichel> <- eating serrano ham pure, direct from the leg...
[17:07:27] <Jymmm> But I could see thermos soup, pastas, and a few other things if you get creative with it
[17:07:41] <alex4nder> Loetmichel: lucky bastard
[17:07:44] <Loetmichel> wifey has been generous yesterday and made me a gift
[17:07:50] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13045
[17:07:54] <alex4nder> Loetmichel: I had hawaiian ham today, but yours looked better
[17:08:34] <Loetmichel> <- getting some more, that stuff is addictive ;-)
[17:09:18] <alex4nder> I wonder if I can buy one online.
[17:09:49] <alex4nder> Loetmichel: if you don't mind me asking, how many euros was your leg?
[17:10:54] <Thadius1> anyone have a good link for engraving and micro end mills?
[17:11:01] <Jymmm> yes
[17:11:22] <Loetmichel> 65 eur for 6.5 kg
[17:11:31] <alex4nder> damn
[17:11:32] <alex4nder> you suck
[17:11:39] <Jymmm> Thadius1: http://www.precisebits.com/applications/pcbtools.htm
[17:11:39] <alex4nder> it's 33 euros/kg here.
[17:12:11] <Loetmichel> Thadius1: which country?
[17:12:24] <Loetmichel> i buy my mills at www.mmetoolshop.de
[17:12:45] <Jymmm> Thadius1: http://www.thinktink.com/stack/volumes/voli/store/mechmill.htm
[17:12:47] <Loetmichel> sometimes a bit slow in delivery but very cheab and reliable tools
[17:13:15] <Thadius1> ty Jymmm
[17:13:24] <Jymmm> Thadius1: np
[17:14:00] <asdfasd> I wish I have more time Im sure I can improve a lot the PCBs
[17:14:18] <asdfasd> what softuare you are using for G code
[17:18:07] <Thadius1> and thanks Leotmichel as well
[17:19:59] <Loetmichel> Thadius1: my last delivery: http://www.cyrom.org/palbum/main.php?g2_itemId=13000
[17:22:23] <asdfasd> the only I found when I made these 2 pcbs 4 yars ago was a g code plugin for eagle
[17:23:06] <asdfasd> any new and better?
[17:25:47] <Loetmichel> asdfasd: i use target 3001
[17:26:01] <Loetmichel> which can output gcode out of the box ;-)
[17:26:11] <Loetmichel> ... and read eagle files ;-)
[17:27:33] <asdfasd> 250 points for free....
[17:27:37] <asdfasd> not too bad
[17:48:38] <asdfasd> it looks fine, a bit complicated but I made one G code from the examples
[19:00:24] <Tecan> how do i figure out pully teeth and leadscrew pitch for a belt drive ?
[19:03:39] <Tecan> revolutions per inch... im just not sure yet
[19:04:49] <Tecan> callipers ?
[19:05:17] <asdfasd> you mean for emc settings?
[19:05:25] <Tecan> yes
[19:06:15] <asdfasd> what I did is to calculate my steps per mm on the machine
[19:06:31] <asdfasd> then I setup a screw pitch 1mm
[19:06:41] <asdfasd> and I entered my steps per mm
[19:06:56] <Tecan> 1 revolution = 45 mm
[19:07:27] <asdfasd> how many steps you have to make that 1 revolution
[19:07:43] <Tecan> so leave pully teeth as 1 ?
[19:07:54] <asdfasd> yes
[19:10:11] <asdfasd> drive microstepping also 1
[19:10:48] <asdfasd> and motor steps per rev, you can enter the calculated step per mm for your machine
[19:11:20] <Tom_itx> the pulley ratio can be calculated from the teeth
[19:15:12] <asdfasd> oh sorry you are doing in inches
[19:21:51] <djdelorie> could you set your screw pitch to *be* the "inches per revolution", and leave the steps/rot alone?
[19:22:44] <djdelorie> i.e. with a 5 tooth/in belt, and a 20 tooth gear, that's 4in per rot. Set your "screw" to 1/4 TPI (not 1/4" pitch) ?
[19:29:28] <jdhnc> end up the same.
[19:30:18] <mrsun> i set my screwt o 2mm lead (im metric), steps to 200 (my steppers has 200 steps/rev) and microsteping to wahtever microstepping i have
[19:30:22] <mrsun> gear ratio 1:1
[19:30:39] <mrsun> as im directly coupled to the leadscrew
[19:32:46] <djdelorie> leadscrews are easy, just fill in the numbers. It's timing belts that are tricker
[19:33:01] <asdfasd> I think you can do the same with timing belt
[19:33:20] <asdfasd> you can enter these 45mm as pitch
[19:34:11] <asdfasd> but finally is calculated as steps per unit, and then entered in ini file
[19:36:56] <Tecan> to print the emc logo it keeps saying that its going to hit my limit switch.. gaa
[19:37:27] <Tecan> should home switch location be negatice or the table travel ?
[19:38:16] <asdfasd> depends of your machine configuration
[19:41:11] <asdfasd> with wrong settings it is homing in wrong direction
[19:41:38] <Tecan> oh i see its wanting my z axis when there is none
[19:44:34] <asdfasd> you dont have Z?
[19:50:54] <jdhnc> uhm. Yeah!
[19:51:14] <pfred1> um, OK?
[19:51:30] <Tom_itx> jdhnc, did that sub stuff work ok?
[19:53:30] <jdhnc> mostly. had some Z issues after swapping to g55
[19:55:35] <Tom_itx> z should have been set the same
[20:21:40] <Tecan> how come the spindle wont turn off when done ?
[20:21:49] <Tecan> the pwm keeps comming
[20:21:59] <Tom_itx> did you tell it to shut off?
[20:22:23] <Tom_itx> M5
[20:22:24] <Tecan> no but i turned everything on without my special glasses
[20:23:21] <Tecan> how do i tell it that ?
[20:23:29] <Tecan> i see the mdi command box
[20:24:01] <Tom_itx> there should be a spindle on off button there somewhere iirc
[20:24:25] <Tecan> hmm it was already pushed in
[20:24:47] <Tom_itx> maybe your logic is backwards
[20:25:10] <Tom_itx> i had to invert most of mine
[20:27:14] <Tecan> yes that worked
[20:27:51] <Tecan> whats pdm mode for pwm rate ?
[20:28:15] <Tecan> then it says speed 1 and pwm 1
[20:28:21] <djdelorie> pulse dithering mode?
[20:28:28] <Tecan> weird
[20:29:13] <Tecan> pulse density modulation
[20:42:32] <Tecan> well it worked
[20:42:43] <Tecan> went through like 5 sheets of paper
[21:01:02] <Tecan> http://i.imgur.com/eP9tk.jpg
[21:03:26] <pfred1> Tecan looking good
[21:19:27] <WillenCMD> hey everybody, hope all had a good easter
[21:20:41] <WillenCMD> does anyone know if anyone has had luck using the altera cyclone 2?
[21:22:34] * djdelorie is a xilinx guy...
[21:23:55] <WillenCMD> yes but cost is a issue, mesa cards are great but the cyclone ii is a fourth the price
[21:23:55] * pfred1 wants multiple cursors
[21:24:17] <pfred1> how come we only have one?
[21:24:27] <pfred1> we have 2 hands
[21:25:09] <WillenCMD> screw a mouse, i want to use my mind
[21:25:23] <pfred1> I seen that in a store once
[21:25:30] <WillenCMD> i watched a tv show about it
[21:25:33] <pfred1> this band yo ustrapped to your head
[21:26:09] <WillenCMD> using it on paralyzed patients, takes a long time to calibrate, but it maps brain wave changes
[21:27:47] <pfred1> computers have rendered me effectively paralyzed anymore
[21:28:04] <pfred1> I sit in front of them long enough I might as well be
[21:28:47] <djdelorie> One expects gaming accessory stores to start offering catheters for gaming chairs, so you never have to get up...
[21:29:16] <pfred1> nah you need the idiocracy easy chair with a flush handle on the side
[21:29:20] <WillenCMD> i solved that, i just married a nurse
[21:29:40] <pfred1> go away 'batin!
[21:29:45] <WillenCMD> iv fluids, plus cath= gaming 24/7
[21:30:10] <pfred1> I played a MUD once for just about 3 days straight
[21:30:17] <Jymmm> gamin 24/7 == divorce
[21:30:37] <WillenCMD> emc2 24/7 == divorce also, it gets lonely in my basement
[21:30:58] <WillenCMD> good thing i use virtual machine for developing and testing
[21:31:53] <WillenCMD> i hooked an ip-cam up to my mill so i can monitor long gcode runs without disturbing the emc2 computer :)
[21:32:29] <pfred1> I almost bought a webcam at the flea market yesterday
[21:33:07] <WillenCMD> i unhooked the ir, wired it to a relay, and i can toggle the estop via the web interface
[21:33:15] * pfred1 bought this instead http://i.imgur.com/r5W20.jpg
[21:34:15] <pfred1> that SImpson is in some tough shape
[22:03:41] <Tecan> awe sweet got the pwm working
[22:09:53] <Tecan> dam image to gcode wont work because it wants a y axis
[22:10:07] <Tecan> i only have x and z
[22:11:31] <djdelorie> lie to it :-)
[22:12:06] <Tecan> why when the source code is there
[22:12:48] <djdelorie> you have to add the lie-to-me option to the sources :-)
[22:13:26] <djdelorie> are you using a slice through an image to run a lathe?
[22:31:41] <Tecan> http://i.imgur.com/9SY1q.jpg
[22:58:12] <Tecan> i might just pull all my hair out tonight
[22:58:19] <Tecan> been wanting to go bald for a while
[22:58:55] <Tecan> Graster needs to be updated or is it obsolete ?
[23:09:55] <Tecan> not needed i guess
[23:14:40] <Thadius1> hello all
[23:23:17] <Tecan> thadius1 your working on laser too ?
[23:23:36] <Thadius1> working on cnc mill
[23:23:45] <Tecan> you like to party ?
[23:23:54] <Thadius1> back in my youth lol
[23:24:06] <Thadius1> not so much anymore
[23:24:15] <Tecan> ok we'll just mill stuff then
[23:24:22] <Tecan> good sounding ?
[23:24:26] <djdelorie> mill party!
[23:24:47] <Tecan> not a run of the mill party though
[23:24:57] <Tecan> this'll be epic mill party
[23:25:59] <Tecan> i think the laser is making me blind
[23:26:22] <djdelorie> do not look into laser with remaining eye
[23:26:48] <Tecan> even looking at the burning part with protective glasses on
[23:26:56] <Tecan> things get blurry after
[23:27:37] <Thadius1> man, ordering all my stuff tonight
[23:27:49] <Thadius1> v90, spindle, software, ect ect
[23:28:15] * djdelorie is putting together a shopping list for lathe accessories...
[23:28:48] <djdelorie> the tricky part is matching up modern accessories with a 90-year-old lathe
[23:28:54] <Thadius1> yikes
[23:30:08] <djdelorie> this thing even predates threading dials ;-)
[23:35:29] <Tecan> who does python here ?
[23:35:51] <Tecan> im trying to find from rs274.author import Gcode
[23:36:04] <Tecan> need to make image to gcode run standalone
[23:36:21] <Thadius1> anyone mess with "Meshcam" by any chance?
[23:36:50] <Tecan> sounds like windows junk
[23:37:35] <Thadius1> CAD/CAM software thats been around since 2008 i believe
[23:49:32] <alex4nder> hey
[23:49:49] <alex4nder> Thadius1: I've used MeshCAM.. it's 'ok'
[23:56:38] <Tecan> sweet
[23:56:42] <Tecan> got it isolated
[23:57:32] <Thadius1> ty Alex
