[02:33:08] <spastic_teapot> Hello everyone.
[02:33:31] <spastic_teapot> Is anyone here familiar with electroplating?
[03:41:27] <SWPadnos_> SWPadnos_ is now known as SWPadnos
[07:35:03] <tomp> handy tool for all those incompatible acad versions w$ only

[07:47:52] <KimK> Is anybody around that can try sending me a small test file? I seem to be having trouble receiving IRC file transfers from a friend, and a comparison might help troubleshooting.
[07:55:01] <fragalot_> hmm
[07:55:12] <fragalot_> apparently, my laptop runs at 16819Mhz
[07:55:14] <anonimasu> KimK: use something like "filebin.ca" instead
[07:55:35] <anonimasu> KimK: and look over what your client tinks your external ip are
[07:55:58] <fragalot_> http://omploader.org/vd3pt/Screenshot.png -- win?
[07:57:00] <anonimasu> ^_^
[07:57:11] <anonimasu> hm, I need to make a adapter plate for the grinder today
[07:57:46] <anonimasu> toolpost grinder
[07:57:50] <fragalot_> 48Ghz now, lol
[07:59:11] <KimK> anonimasu: thanks, but I'm trying to troubleshoot my IRC client. It is offering me the file transfer OK, I just can't get "accept" to work.
[07:59:38] <anonimasu> did you read what I just said?
[07:59:53] <anonimasu> check what your client thinks your ip are
[08:00:58] <KimK> I'll look, but don't think that's an issue or I wouldn't have the beginning of the transfer
[08:01:57] <anonimasu> * anonimasu sighs
[08:02:22] <anonimasu> http://www.irchelp.org/irchelp/rfc/dccspec.html
[08:02:44] <anonimasu> the request goes over ctcp(ie over the irc server)
[08:03:05] <fragalot_> lappy locked up
[08:03:08] <anonimasu> whereas the actual file transfer goes directly to your client from the other computer(direct client to client)

[08:29:19] <alex_joni> alex_joni has changed the topic to: Welcome! EMC (Enhanced Machine Controller) is a linux-based opensource CNC control. | Latest release: EMC 2.2.7 |
http://www.linuxcnc.org |
http://wiki.linuxcnc.org
[09:05:55] <archivist> oooo 2.2.7 :)
[09:21:57] <anonimasu> hmm
[09:38:17] <anonimasu> *yawns*
[09:38:34] <archivist> * archivist waits for coffee
[09:38:49] <anonimasu> :)
[09:39:06] <anonimasu> hm, too bad I've got a lesson in a it otherwise I could be machining stuff all day long :)
[09:39:44] <anonimasu> maybe fit some time to stick the grinder adapter plate in the mill .)
[09:39:45] <archivist> I just run update on the working box /me a trusting person
[09:40:14] <anonimasu> hehe
[09:40:51] <archivist> I dont see bugs thrown around like some projects I could mention
[09:41:01] <anonimasu> :)
[09:41:18] <anonimasu> I wonder how good I could grind a toolholder
[09:42:18] <archivist> how good can you dress the wheel and how good are your bearings
[09:43:11] <anonimasu> better then 0.013 that the china tooling specifies -_-
[09:43:57] <anonimasu> :)
[09:45:05] <archivist> I notice a cyclic error on the headstock of the Schaublin lathe, needs new bearings
[09:45:34] <anonimasu> * anonimasu nods
[09:46:11] <archivist> but its worn out, bed, broken screw thread tumbler, brokend screws in tailstock cant adjust
[09:46:42] <anonimasu> I see :/
[09:46:58] <anonimasu> I'm excited about my scraper arriving ^_^
[09:47:03] <archivist> could cnc and add error compensation to fix
[09:47:16] <anonimasu> for the cyclic error?
[09:47:17] <archivist> Lazy method
[09:47:21] <anonimasu> :p
[09:47:30] <anonimasu> if you had linear motors ;)
[09:47:31] <archivist> no that has to be new bearings
[09:48:01] <archivist> its like one large ball in the race
[09:48:15] <anonimasu> I know
[09:48:31] <anonimasu> if you have linear motors with a insane frequency response you can ~ to compensate ;)
[09:48:37] <anonimasu> against the spindle encoder ;p
[09:49:52] <anonimasu> * anonimasu is just kidding
[09:50:25] <archivist> and being an old flat belt driven design you cant get any poer to the cut
[09:50:32] <archivist> power
[09:51:07] <anonimasu> * anonimasu nods
[09:54:47] <anonimasu> brb
[09:54:48] <anonimasu> lunch
[09:55:34] <anonimasu> well in 5 minutes

[12:21:00] <piasdom> g'mornin all
[12:30:26] <anonimasu> morning
[12:32:20] <anonimasu> hm..
[12:42:09] <piasdom> sir ?
[12:43:02] <anonimasu> * anonimasu is pondering surface finished on small dia work
[12:43:10] <piasdom> k
[12:43:40] <archivist> define finish and what do do you call small
[12:43:58] <BigJohnT> piasdom: I got all the things fixed that you found, I think, thanks
[12:44:06] <archivist> we do near mirror at 1.mm
[12:44:14] <archivist> .1mm
[12:44:20] <piasdom> BigJohnT;NP
[12:45:05] <piasdom> BigJohnT:i was giving the page number in the doc, not from the reader
[12:45:15] <fragalot> *yawn*
[12:46:15] <BigJohnT> it is different for me as I'm looking at the chapters as seperate docs and they don't have page numbers yet...
[12:47:16] <piasdom> BigJohnT:oh ok...want me to go get the chapter and para ?
[12:48:00] <BigJohnT> yes if you can
[12:48:09] <piasdom> NP
[12:48:43] <anonimasu> archivist: 6mm or so
[12:48:58] <archivist> ah big :)
[12:49:18] <anonimasu> I get ground finishes on 50mm dia stuff :)
[12:49:18] <anonimasu> almost
[12:49:44] <anonimasu> 0.014 per rev of feed
[12:49:55] <archivist> I got some nice finishes last week on free cutting steel
[12:49:56] <anonimasu> err 0.14
[12:49:58] <anonimasu> sorry
[12:50:05] <anonimasu> 0.14mm/rev
[12:50:16] <BigJohnT> for example user manual G Code 13.4 Indirection gets me right to the spot :)
[12:50:30] <fragalot> finishing is for wussies. ^_^
[12:50:54] <anonimasu> I like cranking out stuff that looks like someone skilled made it :p
[12:50:57] <archivist> finishing is for bearing fits
[12:51:09] <anonimasu> yep
[12:51:19] <fragalot> nah. :p
[12:51:27] <archivist> and clocks to look "pretty"
[12:51:35] <anonimasu> :)
[12:51:39] <fragalot> archivist: if done right the first time, it already looks "pretty"
[12:51:41] <anonimasu> or parts to look pretty
[12:51:51] <anonimasu> * anonimasu sighs
[12:51:56] <fragalot> why am I even trolling on that subject
[12:52:00] <anonimasu> stop trolling
[12:52:06] <anonimasu> it dosent matter I want mirror finishes
[12:52:10] <archivist> fragalot, no machining marks to show on a clock
[12:52:12] <anonimasu> :p
[12:52:16] <fragalot> k, don't have anything better to do
[12:52:30] <anonimasu> figure my issue out ;)
[12:52:45] <anonimasu> ie I have nfc what feeds/speeds to use
[12:52:47] <fragalot> anonimasu: .1mm @ proper feed
[12:52:52] <fragalot> calculate it
[12:53:18] <anonimasu> my tooling states 0.14 :)
[12:53:27] <fragalot> then do .14 :p
[12:53:39] <anonimasu> but at what kind of speed..
[12:53:55] <fragalot> "calculate" or look it up in a table
[12:54:12] <archivist> material and cutter and coolant all effect
[12:54:12] <anonimasu> yes, im looking for the formula
[12:54:37] <anonimasu> construction steel free machining
[12:55:56] <anonimasu> finish changes with dia as it seems to me
[12:56:38] <archivist> yes the surface speed changes with dia, so adjust to keep near constant
[12:56:54] <anonimasu> how do you calculate it?
[12:57:06] <anonimasu> (I cant find the fomula in my machinists handbook)
[12:57:21] <archivist> not looking hard enough
[12:58:06] <anonimasu> gee, thanks alot for the help.
[12:58:08] <archivist> rpm*circumference = distance per min
[12:58:23] <anonimasu> ah, thanks
[12:59:00] <archivist> in whatever units you feel like
[13:00:23] <anonimasu> ends up at about 80m/min
[13:02:25] <anonimasu> but I still cant find it in my handook
[13:03:21] <anonimasu> (rather how to keep that constant on smaller dia work)
[13:04:28] <archivist> well most machines dont keep it constant just choose the best to suit, or adjust if you can
[13:04:46] <anonimasu> the question is how
[13:04:48] <anonimasu> :)
[13:04:55] <archivist> I tend to run as high a speed as I can
[13:05:34] <anonimasu> just keep the feed and increase the speed?
[13:05:52] <archivist> Schaublin is adjustable while running (but I rarely bother once cut is underway)
[13:10:08] <acemi> how to write to an I/O address in python? something like outb
[13:11:39] <alex_joni> acemi:
http://pyserial.wiki.sourceforge.net/pyParallel ?
[13:11:58] <alex_joni> or maybe
http://www.hare.demon.co.uk/ioport/ioport.html
[13:12:01] <acemi> not for serial or parallel port
[13:12:32] <archivist> see code for technique
[13:12:36] <alex_joni> it shouldn't matter..
[13:14:08] <acemi> alex_joni: do you mean to use pyserial module to write any I/O space
[13:14:20] <acemi> after changinf base address
[13:14:38] <alex_joni> ioport looks cleaner
[13:14:46] <alex_joni> I think it should work on any address..
[13:15:48] <anonimasu> archivist: I dont get how to keep it constant at 6mm dia stuff
[13:15:53] <acemi> ioport is not in debian repo. this is not a big problem but I prefere to use a standart module
[13:16:01] <anonimasu> archivist: decrease the feed per rev?
[13:16:11] <alex_joni> acemi: this was just a quick google
[13:16:28] <acemi> thanks
[13:17:38] <archivist> anonimasu, for all the tiny stuff here I just whack the lathe to top speed and adjust feed to "feel right"
[13:17:57] <anonimasu> hehe, I see
[13:18:16] <archivist> as also at that size deflection starts to be a problem
[13:18:20] <anonimasu> yep
[13:18:24] <anonimasu> brb
[14:38:02] <skunkworks_> stustev: how is the 5 axis machine doing?
[14:59:26] <jepler> acemi_: there's almost certainly no direct hardware I/O built into python.
[14:59:46] <jepler> there's also the problem of the permission for direct hardware access -- you can't make a .py file setuid root, and that's required for direct hardware I/O with inb/outb/etc
[15:14:06] <BigJohnT> http://www.cnczone.com/forums/showthread.php?t=67971
[15:15:21] <skunkworks_> I had one computer that when emc wasn't running - there was output from the printer port. It would run z right into the table.
[15:15:26] <skunkworks_> never did figure that out.
[15:15:31] <skunkworks_> just one computer.
[15:15:37] <cradek> open trash can, insert computer
[15:15:53] <skunkworks_> yeh - I think it is long gone.
[15:16:17] <skunkworks_> I know you guys had walked me thru a few things. but it didn't fix it.
[15:17:05] <SWPadnos> could have been some cups daemon thngs
[15:17:07] <SWPadnos> thing
[15:17:24] <archivist> windaz outputs carp on the parport on my box
[15:17:36] <jepler> SWPadnos: that's why we disable the regular kernel parport module
[15:17:46] <archivist> dont see it in ubuntu though
[15:18:10] <SWPadnos> jepler, I figured this was some time ago, since skunkworks_ said the machine is long gone :)
[15:18:26] <jepler> SWPadnos: wvlaeminck is reporting it to day though
[15:18:59] <SWPadnos> oh, interesting. is that in an email?
[15:19:16] <jepler> SWPadnos: the cnczone link above from bigjohnt
[15:19:25] <SWPadnos> oh. silly me - didn't notice it
[15:20:47] <jepler> I wonder if some system tristates all bits on its parport until probe_parport is loaded .. that plus a driver that lacks pull-up/down resistors on its inputs could exhibit a problem like this
[15:22:36] <skunkworks_> it was when I had the hermes. so - maybe a year ago.
[15:29:08] <skunkworks_> my drives where directly hooked to the printer port. the inputs to the drives where opto-isolated. It think it was actual logic.
[15:38:41] <BigJohnT_> dang lumpy internet
[15:40:27] <jymm> * jymm read that as: skunkworks_ | it was when I had the herpes. so - maybe a year ago.
[15:42:37] <jymm> skunkworks_: sorry

[16:10:04] <cradek> The guage is in good condition. It is in its origional wooden case.
[16:10:19] <SWPadnos> heh
[16:10:27] <SWPadnos> the half that's there looks good
[16:10:57] <BigJohnT> I'm guessing he don't know the difference :)

[16:12:51] <SWPadnos> well, the "guage" is in good condition. it's the other caliper arm that's missing
[16:13:47] <cradek> the origional guage?
[16:14:13] <cradek> I shouldn't laugh because I can't type either.
[16:14:18] <SWPadnos> that's unknown. we only know that the case is origional
[16:14:30] <skunkworks_> Is he selling the other part in a different auction? :)

[18:31:24] <anonimasu> ^_^
[18:31:25] <anonimasu> what's up?
[18:31:43] <anonimasu> I started cutting the mount for the grinder today
[18:32:08] <anonimasu> I'm just goind to make the part in my cam program and leave the machine running while I clean the lathe meanwhile, I think
[18:32:38] <anonimasu> :)
[18:40:11] <fragalot> +ITS ALIVE+
[18:40:28] <fragalot> :D I just got my parallel cable, and hooked the steppers up to the circuitry to give it a few runs on EMC.... :D
[18:40:48] <archivist> bought time too
[18:41:04] <archivist> :)
[18:41:06] <fragalot> Aye,..
[18:41:12] <fragalot> ordered the cable from dx.com, lol
[18:41:58] <archivist> 4 steppers?, play daisy.ngc
[18:42:08] <fragalot> XYZ
[18:42:13] <fragalot> 3 steppers
[18:42:35] <archivist> have to edit A from the file to play on 3 axis
[18:42:44] <fragalot> currently it's playing with spiral, as i only hooked one up to get the axis calibrated.. (the wires are just... sortof... twisted right now, lol)
[18:43:03] <archivist> bolt the buggers down
[18:43:49] <fragalot> haven't finished the machine itself yet
[18:44:07] <fragalot> they are just laying on the table, vibrating :p .. but i mean the wires are just twisted together instead of connecting them properly for now
[18:44:54] <archivist> * archivist put a bid in fleabay for a cnc engraver
[18:45:01] <fragalot> :o
[18:45:15] <archivist> £6 at the moment
[18:46:23] <fragalot> o.0
[18:46:29] <fragalot> where :p
[18:46:36] <fragalot> (I won't bid, don't have the money, just wanna see it)
[18:47:45] <archivist> http://cgi.ebay.co.uk/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWAX:IT&item=260312407320
[18:48:02] <archivist> * archivist notes another bid!!
[18:48:27] <fragalot> coincidence
[18:48:35] <fragalot> ooh, tiny
[18:49:06] <archivist> would make a small PCB making machine
[18:49:18] <fragalot> Aye, it'd be perfect for that
[18:50:14] <fragalot> bzzzzwhiiiiiiieeeeeeeeiiiiihhhwwrrrrr == sounds i'm hearing atm with the stepper motors laying down on sheet metal, lol
[18:59:54] <fragalot> I think my X axis is broken
[18:59:56] <fragalot> :(
[19:09:55] <anonimasu> hmm
[19:09:58] <anonimasu> 7 days to get a package from england
[19:10:31] <alex_joni> boat?
[19:11:07] <anonimasu> haha
[19:11:08] <anonimasu> no
[19:11:10] <anonimasu> air
[19:11:21] <anonimasu> I think
[19:15:50] <anonimasu> hm..
[19:15:59] <anonimasu> I wonder if toolfastdirect forgot to ship the scraper
[19:16:59] <fragalot> it got pwnt by customs
[19:17:00] <fragalot> :p
[19:17:53] <fragalot> gah, why isn't my X axis working :/ I don't feel like breaking the PCB out again :(
[19:18:18] <anonimasu> heh
[19:18:50] <anonimasu> :/
[19:22:07] <fragalot> it COULD be the enable pin, as i don't get any outputs from it
[19:22:56] <fragalot> nvm, I do
[19:23:17] <anonimasu> -_-
[19:23:24] <anonimasu> crap
[19:24:00] <fragalot> BigJohnT: expected signals show up on output pins of driver, hooking stepper up that works on the other axes doesn't. What is the problem. :p:p
[19:24:55] <BigJohnT> the knuter valve is stuck open
[19:25:08] <fragalot> I see. Do i fix that by replacing the flux capacitor?
[19:25:41] <BigJohnT> yes, but you must be careful not to spill any anti-matter out
[19:25:55] <fragalot> wait
[19:26:04] <fragalot> the dark matter is under the minimal level
[19:26:32] <fragalot> so anyways, the X axis just holds and randomly jumps a spot.. the Y and Z work fine
[19:26:35] <fragalot> work great, even :D
[19:26:59] <anonimasu> driver/motor?
[19:27:47] <BigJohnT> worked once? or new install?
[19:28:04] <fragalot> L297-298 + ITC-CNC-1 motor (1.8°/200step, 12V running at 24V, .39A)
[19:28:12] <fragalot> BigJohnT: new "testbed" :p
[19:28:28] <fragalot> it's just motors running free & the driver i made for it, still working on the machine itself
[19:30:45] <fragalot> fyi, I'm just unplugging the motor from one axis, plugging it into the other, so it's no thte wiring that gets messed up.. Has to be the PCB, or the breakout board
[19:30:57] <BigJohnT> yep
[19:30:57] <fragalot> if only my scope wasn't so damn useless
[19:32:00] <fragalot> other than that, it's handling tort.ngc quite well sofar without heating up
[19:36:36] <BigJohnT> * BigJohnT heads out to the factory
[19:44:13] <skunkworks_> fragalot: without mass hooked to the stepper - you might get resonence stalling.
[19:44:17] <skunkworks_> resonence?
[19:44:25] <skunkworks_> without any micorstepping
[19:44:37] <fragalot> it didn't stall
[19:45:22] <skunkworks_> http://lumenlab.com/brainchild/
[19:45:43] <fragalot> mmph, the LM317's sure get hot..
[19:46:15] <fragalot> hahahhaha
[19:46:45] <fragalot> dude, that "torch test" made obama look way better than it was at first
[20:16:35] <fragalot> http://www.instructables.com/id/3D-chocolate-printer-made-from-LEGO/ that's the way, uhu uhu, I like it, uhu uhu
[20:19:28] <archivist> some people have more time than sense :)
[20:28:53] <fragalot> :D I wonder if it actually worked
[21:13:46] <anonimasu> hm
[21:13:50] <anonimasu> I like scraping stuff.
[21:15:14] <archivist> * archivist posts 5 tons to sweden for scraping
[21:15:42] <anonimasu> hehe
[21:16:00] <anonimasu> it'll be fun once I get proper paint to do it too..
[21:16:26] <archivist> I wonder how long you will like scraping for
[21:17:03] <anonimasu> lol
[21:17:13] <anonimasu> I like the fact that the surface ends up as good as the effort you put into it
[21:17:31] <anonimasu> :p
[21:18:06] <SWPadnos> I prefer a nonolinear quality:effort ratio
[21:18:31] <anonimasu> hehe
[21:18:31] <skunkworks_> exponential?
[21:18:45] <SWPadnos> well, I'm not that demanding
[21:18:49] <anonimasu> hmm
[21:19:37] <archivist> start with the classic 3 surface plates, make flat
[21:20:20] <anonimasu> I'm going to start with a straightedge
[21:20:28] <anonimasu> or a surface plate
[21:20:30] <anonimasu> :)

[21:33:37] <tomaw> [Global Notice] Hi all. That split has taken services and 10k with it. We're currently investigating the cause and hope to have it resolved soon. Further updates via wallops (/mode <nick> +w). Thanks!
[21:52:09] <christel> [Global Notice] Hi all! Terribly sorry for that (fairly substantial) split! Unfortunately one of our sponsors experienced routing issues affecting our secondary US hub, Services and one of our largest MRS servers.. The issues are hopefully fixed for now, but if you have some spare connectivity and hardware, perhaps you should consider helping us not keep all our eggs in one basket! Again, sorry and thanks for using freenode!
