[00:05:36] <memleak> Hello. I'm building RTAI and EMC from scratch, all by hand, I spent the past few hours modifying the ipipe kernel patches and I went to run latency-test and I have two unknown symbols in rtapi.
[00:05:58] <memleak> floor and frexp. I'm using the EMC v2.5_branch tree from git.
[00:07:20] <memleak> kernel version is 2.6.38.8 and the problem in EMC seems to be in src/rtapi/rtapi_math.h
[00:09:14] <pfred1> I don't think rtai works on a kernel that new
[00:09:48] <A0Sheds> it does now :)
[00:10:23] <A0Sheds> now his problem is with EMC
[00:10:31] <pfred1> half the time it doesn't work to oswift on kernels it is supposed to work on
[00:11:04] <A0Sheds> thats why he's doing what he's doing :)
[00:13:02] <pfred1> I used 2.6.30.5
[00:38:05] <KimK> A0Sheds: What kind of wire edm unit? Tell us about it.
[00:39:54] <Jymmm> $8500 one
[00:44:46] <A0Sheds> KimK: old Elox unit
[00:47:39] <A0Sheds> http://imagebin.org/210436
[01:20:14] <KimK> A0Sheds: Thanks. But I thought you said wire unit. Isn't that a sinker?
[01:20:43] <KimK> A0Sheds: Or am I looking at it wrong?
[01:42:25] <KimK> A0Sheds: Oops, got to go, I'll check back later.
[04:59:30] <DJ9DJ> tag
[04:59:51] <DJ9DJ> good day! ;)
[05:19:46] * archivist looks out at the rain and disagrees
[05:29:08] <r00t4rd3d> http://millionshort.com/
[06:20:16] <archivist> does seem to find smaller sites
[06:22:42] <IchGuckLive> hi all i did it today in a matter of ... the Airfoil G-code generator for my XYUV Foam cutter ->http://www.youtube.com/watch?v=ApZLjXWWC6k
[06:23:00] <IchGuckLive> the collor is read but on youtube its blue ? ! O.O
[06:24:32] <IchGuckLive> i thik this will overrun my channel as the foamcutter modification to linuxcnc is requestet over 2K times
[06:24:57] <IchGuckLive> see you 19000 MESZ
[06:40:42] <r00t4rd3d> RTAI[hal]: ERROR, LOCAL APIC CONFIGURED BUT NOT AVAILABLE/ENABLED.
[06:41:15] <r00t4rd3d> Error when I try and run latency test
[06:42:56] <r00t4rd3d> Why on earth is so much personal information required to register on the forums?
[06:49:36] <jthornton> which forums?
[06:50:19] <r00t4rd3d> linuxcnc
[06:51:17] <jthornton> because we get from 50 to 100 spammers that try and register each day and we need a way to filter them out...
[06:51:28] <r00t4rd3d> come on
[06:51:43] <r00t4rd3d> thats a line of shit
[06:51:45] <jthornton> not much personal about city, state, country and zipcode
[06:52:11] <r00t4rd3d> then i fill it all out and the page just resets and blanks the entries
[06:52:20] <r00t4rd3d> when i clicked register lol
[06:53:10] <jthornton> what's your ip address? I can check for banned ip's
[06:53:23] <r00t4rd3d> holy shit now you want my ip ?
[06:53:47] <jthornton> not really I have other things to do
[06:54:04] <archivist> r00t4rd3d, I dont think you realise how bad the spam problem is
[06:54:43] <r00t4rd3d> a spammer can fill out first name last name address state city and country too
[06:54:55] <jthornton> hmmm very slow the last 10hrs only 27 spammers to filter out this morning
[06:55:23] <jthornton> LOL and you should see what they put in there
[06:55:55] <r00t4rd3d> on google search it says linuxcnc.com might be compromised
[06:56:01] <archivist> I think the wrong forum software was used, mine gets filtered automatically a bit
[06:56:33] <jthornton> yea it is a PIA to manage since we upgraded Joomla
[06:56:49] <archivist> r00t4rd3d, it was hacked a few days ago, not sure if fixed yet
[06:57:16] <r00t4rd3d> that makes me feel even better about entering all my personal data.
[06:57:22] <jthornton> r00t4rd3d, you also might be using one of the spam blocked usernames
[06:57:29] <r00t4rd3d> <----
[06:57:51] <jthornton> nope that's not on the list
[06:58:22] <archivist> does it look for partial like r00t
[06:58:39] <jthornton> looking
[06:59:12] <jthornton> ok, I see the problem it is the 00
[06:59:24] <r00t4rd3d> aww
[06:59:25] <jthornton> r00t4rd3d, stand by for a moment
[06:59:54] <archivist> jthornton, who is fixing the current hack, anybody?
[07:00:15] <jthornton> ok, I have removed that from the restricted registration you can register with numbers now
[07:00:31] <jthornton> I'm not even aware of the hack
[07:00:47] <r00t4rd3d> http://i.imgur.com/ncbCh.jpg
[07:01:08] <archivist> was reported by a few of us to alex_joni a week or two ago
[07:03:09] <r00t4rd3d> lol it went through
[07:03:15] <jthornton> I only have access to the front end
[07:03:22] <r00t4rd3d> i doubt a moderator is going to approve me though
[07:03:28] <jthornton> why?
[07:03:29] <r00t4rd3d> i lied in some fields
[07:03:48] <r00t4rd3d> obvious lies
[07:04:05] <jthornton> really I look for links to boots and porn and such and zip code of 123456
[07:04:19] <r00t4rd3d> i used 69696
[07:04:40] <jthornton> lol
[07:05:08] <jthornton> did you get the conformation e-mail?
[07:05:11] <archivist> there seems an assumption that all countries have zip codes!
[07:05:12] <r00t4rd3d> yeah
[07:06:53] <jthornton> ok, as soon as I finish blocking spammer ip's I'll take care of it
[07:09:16] <r00t4rd3d> i think i am beat with my error though
[07:09:56] <jthornton> ?
[07:10:17] <r00t4rd3d> I try and run the latency test and get a error.
[07:10:25] <r00t4rd3d> RTAI[hal]: ERROR, LOCAL APIC CONFIGURED BUT NOT AVAILABLE/ENABLED.
[07:10:38] <archivist> r00t4rd3d, have you but a question on the mailing list too
[07:10:54] <r00t4rd3d> no
[07:11:13] <jthornton> that sounds familiar as soon as I'm done blocking spammers I'll try and find that... I think it is on the wiki
[07:11:20] <r00t4rd3d> it is
[07:11:35] <r00t4rd3d> says to add lapic to grub for an option
[07:11:51] <r00t4rd3d> did it and still the same error
[07:13:04] <archivist> hmm I remember cradek talking someone through a similar thing in here a week or three ago, should be in the logs
[07:15:25] <ReadError> yo
[07:15:34] <r00t4rd3d> do you have a log and can you paste bin what he said?
[07:17:29] <jthornton> logger[mah], log
[07:17:30] <logger[mah]> jthornton: Log stored at http://linuxcnc.mah.priv.at/irc/%23linuxcnc/2012-05-01.html
[07:17:38] <jthornton> you can search it iirc
[07:17:56] <jthornton> logger[psha], log
[07:17:56] <logger[psha]> jthornton: Log stored at http://psha.org.ru/irc/%23linuxcnc/2012-05-01.html
[07:18:02] <jthornton> or this one I forget
[07:18:26] <Tom_itx> r00t4rd3d i want your cc number too
[07:18:33] <Tom_itx> and the security code for it
[07:18:38] <jthornton> lol
[07:18:53] <jthornton> Tom_itx, you need the expiration date for Willy too
[07:20:18] <archivist> r00t4rd3d, cradek | 2012-04-20 21:17:52 | no APIC, boot with the "lapic" boot parameter to force-enable it.
[07:20:51] <r00t4rd3d> yeah i tried that
[07:21:57] <r00t4rd3d> i think the mini itx motherboard i was trying it on is just junk
[07:22:09] <r00t4rd3d> old
[07:22:18] <r00t4rd3d> is a better term i guess
[07:22:57] <jthornton> try 8.04 on older hardware
[07:23:02] <r00t4rd3d> it does run windows 7 and mach3 just fine though
[07:23:16] <r00t4rd3d> yeah i downloaded that this morning
[07:23:19] <jthornton> mach will run on anything without complaining
[07:23:33] <r00t4rd3d> make emc2 do that
[07:23:41] <jthornton> welcome to the forum Willy Wonka from tub lover
[07:23:46] <r00t4rd3d> lol
[07:24:34] <jthornton> emc has to actually work so it is a bit more picky than winblows and mack
[07:25:27] <jthornton> then there is Ubuntu which is ok most of the time with most hardware
[07:25:28] <r00t4rd3d> Now I am all for agrument but windows 7 and mach 3 are working fine here, Ubuntu and LinuxCNC, not so well.
[07:26:01] <r00t4rd3d> I am a Ubuntu master, google r00t4rd3d+Ubuntu
[07:26:58] * jthornton goes to cook a piece of toast
[07:26:58] <r00t4rd3d> I normally can get anything to work.
[07:29:25] <Tom_itx> maybe you're trying too hard. it's pretty simple to install
[07:29:41] <r00t4rd3d> it installed fine
[07:29:42] <Tom_itx> even i did it
[07:30:14] <r00t4rd3d> running linuxcnc stuff is another story
[07:32:56] <jthornton> I had one computer that I had to install 8.04.4 on as 8.04.0 would not work
[07:33:06] <jthornton> then install the real time kernel
[07:34:48] <r00t4rd3d> im trying 8.04 now
[08:37:12] * JT-Shop needs to practice not getting sucked into kindergarten logic arguments...
[08:40:35] <ReadError> hello
[08:42:07] <pcw_home> olleh
[08:44:26] <JT-Shop> hallå
[08:44:46] <JT-Shop> 你好
[08:45:38] <A0Sheds> JT-Shop, "I'm rubber you're glue..."
[08:46:34] <JT-Shop> LLOOLLL
[08:47:50] <ctjctj> I've looked through most of the docs but can't find the concise answer. I want to place a file of o subroutines where AXIS will read it every time it starts. Does everything that SUBROUTINE_PATH points to get read in?
[08:48:24] <micges> cześć :)
[08:50:41] <JT-Shop> http://www.youtube.com/watch?v=La21jYGIQ8k
[08:51:17] <JT-Shop> ctjctj: no
[08:51:25] <JT-Shop> only when called
[08:53:36] <ctjctj> How do I load those subroutines to work with another ngc file? I.e. CAM program produces tons of gcode type stuff, but I want to do some things via the mdi(?) such as o100 call which is suppose to do some setup stuff for me.?
[08:54:11] <JT-Shop> you should be able to do o100 call in the MDI
[08:55:01] <JT-Shop> the subroutine gets loaded when you call it
[08:55:19] <ctjctj> I'm sorry, I'm being unclear. I have "project.ngc" and "library.ngc" library.ngc resides in SUBROUTINE_PATH. when does library.ngc get loaded? (I'm now very confused)
[08:58:19] <ctjctj> nvm. Tested and got something to work the way I wanted it to. Thank you anyway.
[08:59:11] <JT-Shop> ctjctj: glad you got it to work
[08:59:50] <JT-Shop> ctjctj: was this unclear? http://linuxcnc.org/docview/html/gcode/o-code.html#_calling_files
[08:59:55] <ctjctj> answer: in a directory in your SUBROUTINE_PATH place files. Each file contains exactly one subroutine. The files name should match the subroutine name (o100 becomes 100.ngc). Then call this as "o100 call" documented sort of in 16.6
[09:00:41] <ctjctj> JT-Shop: Yes, it was unclear as it doesn't explain what the search path is. Nor that you can not load a "library file" per say"
[09:01:27] <JT-Shop> darn, I can't link to the ini confg section from there but I'll put a note
[09:01:49] <JT-Shop> not sure what you mean by a library file???
[09:02:31] <ctjctj> Plus the sim/axis/axis.ini does not contain a SUBROUTINE_PATH. SUBROUTINE_PATH only appears in *.ini files where other panels or interfaces are used.
[09:03:02] <JT-Shop> yea, sims may not contain all possible options
[09:03:36] <ctjctj> As a programmer a library is a collection of functions/subroutines. I expected to be able to place a single file with all of my defined subroutines someplace and have AXIS load it or search it when I make o calls.
[09:04:16] <JT-Shop> it will load subroutines as called but not every subroutine
[09:04:24] <JT-Shop> this is G code not C
[09:05:05] <ctjctj> Understood. But "load as called" does not express how the subroutines are found and the section does not even mention SUBROUTINE_PATH.
[09:05:17] <ctjctj> Got to run, I'll check back when I am back to the keyboard.
[09:05:27] <JT-Shop> right that is an ini item
[09:05:49] <JT-Shop> best I can do atm is to put a note about subroutine paths
[09:06:37] <JT-Shop> now we have exploding transformers on the forum
[09:13:24] <JT-Shop> archivist: http://www.google.com/safebrowsing/diagnostic?site=www.linuxcnc.org
[09:15:12] <archivist> JT-Shop, but google is seeing viagra on the site
[09:16:19] <archivist> may not be serving malicious stuff it is serving spam
[09:17:04] <archivist> ttp://support.google.com/websearch/bin/answer.py?hl=en&sqi=2&ei=ae2fT7T_BIiu8APzu6maAQ&answer=190597&?sa=X&ved=0CCsQpwgwAA
[09:17:11] <archivist> +h
[09:20:54] <jthornton> where do you see that it sees viagra?
[09:26:53] <archivist> a google search http://www.archivist.info/cnc/Screenshot-v.png
[09:27:38] <jthornton> oh I see it now
[09:27:40] <cradek> I set my user agent to googlebot, which made it show up for me last time. it's not there now. maybe there was something but it's fixed now?
[09:28:10] <archivist> that pict was just now for me
[09:29:19] <jthornton> my google turned up a cialis one
[09:29:22] <archivist> jymm and pcw also tried changing user agent the other day and saw the problems
[09:29:43] <cradek> ok but I'm trying to understand whether there's a problem right now
[09:30:21] <cradek> I think the answer is no?
[09:30:27] <pcw_home> Pretty sure it was fixed a week or so ago at least the massive breakage
[09:30:43] <cradek> ok thanks
[09:31:14] <archivist> who fixed and did they say they fixed!
[09:31:30] <archivist> else /me is sceptical
[09:31:31] <cradek> I think alex did something
[09:31:32] <pcw_home> unless someone can find a non-cached link thats bad
[09:31:37] <jthornton> the cialis link is this http://www.google.com/url?sa=t&rct=j&q=linuxcnc&source=web&cd=6&ved=0CEkQjBAwBQ&url=http%3A%2F%2Fwww.linuxcnc.org%2Findex.php%2Fdownload%2F21%2F&ei=PvGfT8zxGeKoiAKahqnEAQ&usg=AFQjCNEsRUuQyXnxoEBkdzElvhAP8Nw-eQ&cad=rja
[09:32:33] <jthornton> index.php/download/21
[09:33:23] <jthornton> linuxcnc.org/index.php/download/21/ seems to be the infected file
[09:33:26] <pcw_home> looks ok to me (googlebot user agent)
[09:33:31] <cradek> same here
[09:33:48] <cradek> I actually used "Googlebot"
[09:34:05] <jthornton> I just used a regular google search and it came up
[09:34:17] <cradek> yes but that reports the past
[09:35:01] <Jymmm> alex_joni worked on it, but I dont' recall when
[09:36:42] <jthornton> if google bot crawls your website every few seconds why is a google search so old?
[09:38:56] <cradek> I don't think it does that
[09:38:56] <archivist> in the old days google took a few months to updates its caches and indexes, it is faster now but not instant
[09:39:26] <archivist> for news sites it's exceedingly fast
[09:40:21] <jthornton> if alex_joni fixed a week or two ago shouldn't the caches and indexes be updated by now
[09:40:42] <Jymmm> jthornton: not necessarily
[09:41:10] <Jymmm> jthornton: http://www.google.com/intl/en/help/features_list.html#cached
[09:41:12] <archivist> depends on the allowed crawl rate and how google feels etc
[09:41:23] <jthornton> lol
[09:42:17] <archivist> I watch googles rates on my pages, from a few hundred pages a day to 30k pages a day
[09:42:27] <jthornton> well it's above my pay scale to try and fix that
[09:43:58] <archivist> I have google webmaster tools setup on my stuff
[09:45:07] * jthornton heads back to the shop
[09:46:12] <Jymmm> Ok, I was helping alex_joni on April 22, and google indexed it on April 26. So cradek, I'm guessing we missed something and that there is still some infection somewhere.
[09:47:42] <FredrikHson> hi i was wondering if its possible to run a forth axis without having to home it just manually zeroing it out or if theres some reliable way to make a homing switch for a rotary axis that does not require an encoder or something similar
[09:47:58] <cradek> Jymmm: thanks
[09:48:14] <cradek> FredrikHson: if you set homing velocities to zero, you can home by just manually positioning it
[09:48:41] <cradek> if you have index, you can home ONLY to index too
[09:48:50] <Jymmm> cradek: I'd manually walk thru the db for backdoors.
[09:49:03] <FredrikHson> ok good building my forth axis from some old robot arms using harmonic drives :D
[09:49:07] <cradek> I've let alex know and I hope he works on it soon
[09:49:48] <Jymmm> k
[09:52:49] <Jymmm> alex_joni: grep 'insideblock'
[09:57:12] <JT-Shop> wow joomla current version is 2.5 and we are using 1.5.25
[10:01:25] <JT-Shop> Joomla! 2.5 will be a so called long term release and it will be the Joomla! state of the art until July 2013
[10:02:02] <JT-Shop> User registrations with CAPTCHA
[10:06:58] <archivist> FredrikHson, I currently use a machine level and jog to level then home one of my rotaries, the other is generally a dont care where 0 is
[10:11:08] <Tom_itx> JT-Shop did you find the problem with your psu?
[10:11:21] <Jymmm> alex_joni: Just FYI... http://docs.joomla.org/Vulnerable_Extensions_List
[10:12:12] <FredrikHson> archivist: might do something simpler actually just mill a thin line or something in the casing and the plate that holds the chuck and manually jog it till its close enough
[10:12:57] <FredrikHson> its really only relevant if i shut the machine down before i am done not that i plan on doing that
[10:23:12] <Jymmm> alex_joni: you can also grep for 'eval' and 'iframe'
[10:23:56] <ctjctj> What is "inverse time feed mode" and what sets it?
[10:25:51] <JT-Shop> g code changes to inverse time feed mode
[10:26:42] <JT-Shop> http://linuxcnc.org/docview/html/gcode/gcode.html#_g93_g94_g95_feed_rate_mode_a_id_sec_g93_g94_g95_mode_a
[10:26:59] <ctjctj> thank you.
[10:27:06] <JT-Shop> np
[10:28:11] <JT-Shop> ctjctj: btw I updated the call section http://linuxcnc.org/docview/html/gcode/o-code.html#_calling_files
[10:29:36] <ctjctj> Thank you JT-Shop. That is very helpful. (I'm working from the PDFs mostly but I see the change on your HTML)
[10:30:37] <JT-Shop> the pdf's would have to be downloaded again to get the update which is automagic
[10:30:58] <ctjctj> And I'm beginning to see how you(plural) sort of divide things up. G code is over here in user space. HAL stuff is over there in the integrators side of things.
[10:31:50] <JT-Shop> yes, the plan is to consolidate all info to one pdf so links can be made to anywhere
[10:50:09] <ctjctj> Ok, is there a simulated probe input configuration somewhere? (sorry for being so noob)
[10:56:35] <micges> PCW: hi
[10:57:28] <micges> PCW: what's the version of webpack used for linuxcnc firmwares?
[11:01:49] <pcw_home> I use 13.x for Spartan3 and above and 9.2 for old Spartan 2 stuff
[11:02:11] <micges> thanks
[11:03:40] <pcw_home> I think 13.4 is current
[11:05:27] <micges> yes
[11:13:20] <alex4nder> hmm, building all of the RTAI bits on Debain testing wasn't actually that hard.
[11:21:06] <Jymmm> alex_joni: FYI... there's also the #joomla channel for help as well.
[11:24:48] <Tom_itx> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Touch_Probe
[11:25:16] <Tom_itx> mmm he left
[11:33:26] <joe9> ReadError: you around?
[11:35:35] <JT-Shop> Tom_itx: yea it is broke!
[11:41:54] <ReadError> hey joe9
[12:05:39] <IchGuckLive> hi all around the globe
[12:06:01] <Jymmm> which globe?
[12:06:11] <djdelorie> we only have the one...
[12:06:15] <Tom_itx> Jymmm is on his own planet
[12:06:43] <Jymmm> Tom_itx: DAMN RIGHT! (Scotty beamed me up, cuz this place sucks!)
[12:06:52] <IchGuckLive> did you all see my new airfoil generator ? -> http://www.youtube.com/watch?v=ApZLjXWWC6k
[12:07:29] <IchGuckLive> but on windows its read on linux it is a blue frame dident know why on youtube
[12:08:16] <Jymmm> djdelorie: We HAD 9 planets, then some bastard fscked it all up and we now only have 8!
[12:08:33] <jthornton> IchGuckLive, cool
[12:08:50] <skunkworks__> eh - pluto wasn't a planet.
[12:08:53] <IchGuckLive> the ninth wars not weart to be a planet Jymmm

[12:09:10] <Tom_itx> pluto is an alien drone
[12:09:16] <IchGuckLive> jthornton: thanks did you see the color red or blue
[12:10:13] <Jymmm> Tom_itx: Nah, Pluto is fscking goofy is all <rimshot>
[12:11:17] <jthornton> I'm not sure
[12:11:25] <Jymmm> red
[12:12:07] <jthornton> pj oy
[12:12:16] <jthornton> oh it's nap time then
[12:12:46] <IchGuckLive> thanks i need to overcome some issues with the fata differences of the profiles where to ad the Extra points
[12:13:00] <IchGuckLive> but it works so far
[12:22:56] <IchGuckLive> Folks i need your help as you all know im not the perfect english man are the Data Files on the edu page free of use ? ->http://www.ae.illinois.edu/m-selig/ads/coord/
[12:43:06] <pcw_home> pointy sheep: http://www.mnn.com/earth-matters/animals/stories/photo-sheep-parade-through-hungarian-village
[12:44:57] <andypugh> You wouldn't want to argue with them.
[12:49:01] <pcw_home> supposedly a quite friendly breed (but not available here)
[12:52:18] <pcw_home> http://bayarea.ebayclassifieds.com/livestock/petaluma/american-blackbelly-sheep-rams/?ad=18405421
[12:52:20] <pcw_home> are the rams of the type of sheep we have, but I am forbidden to have a ram here by SO
[12:52:21] <pcw_home> (she thinks I will get careless and butted)
[12:55:45] <andypugh> I assume that "hydraulic rams" are called that for a reason.
[12:57:01] <Jymmm> andypugh: Sounds better than "hydraulic goats"
[12:57:25] <andypugh> OK, i back tracked and founs some very cute piglets.
[12:58:22] <alex4nder> sup
[13:00:10] <Jymmm> andypugh: Bringing on the cuteness... http://i39.tinypic.com/6jhvkl.jpg
[13:00:11] <archivist> large hydraulic rams needed for http://en.wikipedia.org/wiki/Anderton_Boat_Lift
[13:00:42] <andypugh> Not to be confused with the Anderton Boar Lift
[13:01:11] <archivist> I went on it the last year of electric operation

[15:27:04] <sliptonic_shop> After upgrading to 2.5.0 the custom config I'm using to do raster engraving on my laser broke. It's giving me this error: http://pastebin.com/fahMe9Qs
[15:28:06] <sliptonic_shop> The config is based on one documented on buildlog. Code is here: https://github.com/bjj/2x_laser
[15:29:37] <micges> sliptonic_shop: stat.origin was splitted into stat.g5x_offset and stat.g9x_offset
[15:31:46] <sliptonic_shop> micges: Thanks. I'm not much of coder so I might need a bit more to go on. Can you point me to some documentation?
[15:32:21] <micges> I'll look
[15:32:44] <micges> for now just simply rename stat.origin to stat.g5x_offset and it should work
[15:34:22] <micges> I think there is no documentation about this module
[15:34:27] <micges> only source code
[15:34:40] <sliptonic_shop> o.k. I'll try. Thanks.
[15:52:40] <rob_h> nice new video of chnc in action http://www.youtube.com/watch?v=rrLSZy5pwI4
[15:53:47] * Jymmm and JT-Shop would much rather see a nice old chnc in action!
[15:53:52] <syyl_> are you running it with oil as a cooleant?
[15:54:13] <rob_h> yes
[15:54:24] <syyl_> isnt that a horrible mess? :D
[15:54:32] <andypugh> g54x_offset
[15:54:33] <rob_h> depends on oils
[15:54:43] <syyl_> but its running nice
[15:54:52] <rob_h> this one not too bad.. not quite sure on it, might try something else later
[15:54:58] <rob_h> but i had a 205 drum of it, was free so
[15:55:00] <andypugh> Ignore me, typing in the wrong window
[15:55:14] <Jymmm> \ignore andypugh
[15:55:28] <Jymmm> done =)
[15:55:50] <andypugh> I like the idea of oil as coolant, no need to worry about tramp oil skimming.
[15:55:56] <rob_h> that it
[15:56:01] <rob_h> that lthe sits for month some times no use
[15:56:07] <rob_h> so coolant always goes off in it
[15:56:09] <alex4nder> aww yah, the PS3 controller is acting as LinuxCNC pendant and mouse replacement.
[15:56:10] <rob_h> was a pain
[15:56:15] <andypugh> I think Mobil do one meant for spindle lube, way lube and coolant. Sounds ideal.
[15:56:34] <rob_h> yea not made no more
[15:56:38] <rob_h> 400 number one i think 401
[15:56:49] <rob_h> was on mailing list talked about
[15:57:00] <JT-Shop> did you sort out the spindle?
[15:57:11] <rob_h> no not yet
[15:57:22] <rob_h> its doing 3000rpm in that vid
[15:57:25] <JT-Shop> using blood for coolant?
[15:57:39] <rob_h> yea when u out just pop down to local blood bank
[15:57:48] <JT-Shop> LOL
[15:59:54] <rob_h> oil is much cleaner to work with on the parts i find.. and better finish finding too. unless just new ac servos and all the TLC it has had
[16:00:26] <andypugh> It seems that Mobilmet 404 replaced Mobilmet Omicron.
[16:00:51] <andypugh> That was a document from 2010
[16:01:56] <DJ9DJ> gn8
[16:05:09] <andypugh> Ah, looks like you now want 440 for a tri-purpose oil: http://www.mobil.com/UK-English/Lubes/PDS/GLXXENINDMOMobilmet_440.aspx
[16:06:11] <rob_h> just what it is like on misting too on steel, i found on steel what i got there would produce abit of mist
[16:06:19] <rob_h> but filter mist on machine took care of that
[16:08:16] <Tom_itx> what is that crap red lube in the video?
[16:08:20] * JT-Shop is fly cutting a piece of 3" wide steel to taper from 3/8" to 1/8" thick
[16:09:28] <rob_h> Tom_itx, its neating cutting oil that happens to be a red colour.. others are clear. some other shades.. depends what you buy
[16:09:44] <syyl_> i like the red :D
[16:12:33] <JT-Shop> I have a small 1/4hp steam engine kit to build from castings. I've machined cast iron very little any suggestions are welcome.
[16:13:18] <andypugh> It's easy to machine, but makes a mess.
[16:13:56] <syyl_> vac cleaner is nice when machining cast iron
[16:14:08] <syyl_> and you can machine it dry
[16:14:18] <JT-Shop> I have a vac next to the BP
[16:15:09] <Tom_itx> i've seen red oil before just wondered
[16:15:26] <JT-Shop> iirc it makes little tiny chips
[16:15:36] <Tom_itx> the stuff we used was water based and blueish in a concentrate and milky when mixed
[16:16:17] <Tom_itx> i forget what it was
[16:16:30] <Connor> I need to clean out my shop vac before it explodes. :)
[16:16:55] <Jymmm> Connor: toss a match in it, that' clean it out easiest
[16:17:17] <Connor> Yea, but, I want to be able to use after.
[16:17:20] <Connor> :)
[16:17:34] <syyl_> seems like it needs a blowout hatch ;)
[16:17:44] <syyl_> for save exploding
[16:17:45] <Jymmm> You can, as an example of how NOT to clean out a shop vac
[16:17:51] <Connor> Anyone use a vortex infront of their shopvac ?
[16:18:13] <JT-Shop> the base http://imagebin.org/210551
[16:18:33] <Jymmm> syyl_: anybody can make something explode, buy purrrty colors is an art!
[16:18:40] <Jymmm> but
[16:18:53] <Connor> I was thinking of getting one, but, I think I need to get a metal one vs a plastic one.. I think the plastic would be scared up and torn to shreds after a while of being used.
[16:19:09] <Jymmm> JT-Shop: base of?
[16:19:21] <andypugh> Do pay attention Jymmm
[16:19:41] <Jymmm> andypugh: too po, see I can't even afford the 'or'
[16:22:06] <JT-Shop> Jymmm: Model No 6 Steam engine
[16:22:19] <Jymmm> ah
[16:23:18] <Jymmm> all I have is a bench grinder with a so-so wheel, whats the easiest way to thin the edge of a blade?
[16:23:56] <Jymmm> iirc 1065 carbon steel
[16:27:55] <andypugh> I don't think you have the right tool for the job, if you want a neat result.
[16:30:54] <JT-Shop> now to figure out how to hold the base to flatten the bottom
[16:31:53] <andypugh> machine vice and toolmakers jacks?
[16:33:24] <JT-Shop> I have some edge clamps that might work... I need some toolmakers jacks
[16:34:30] <andypugh> You can use nuts and bolts. But you only get so much adjutment, obviously. Do you have long-connector nuts as part of a hold-down set?
[16:36:41] <JT-Shop> no, just the run of the mill hold down set
[16:37:05] <JT-Shop> would you machine the bottom flat first then the top?
[16:37:23] <JT-Shop> seems the bottom is a bit out of level compared to the top
[16:37:38] <andypugh> I would definitely make a reference face of the bottom.
[17:07:56] <alex4nder> sigh
[17:08:15] <alex4nder> hal_input is consuming 50% of this machine's CPU
[17:09:03] * JT-Shop hands alex4nder a cold beer
[17:09:42] <alex4nder> this playstation controller is outputting multi-touch events (?)
[17:14:37] <alex4nder> ... sure enough.. the HID description calls them out as such.
[17:26:31] <JT-Shop> Jymmm: cardboard wheels
[17:56:17] <JT-Shop> what a mess that was
[18:39:22] <andypugh> Am I stil here?
[18:39:43] <micges> yes, you don't ;)
[18:41:26] <micges> (my friend after 6 years of learning english could only say 'Yes, I don't' and 'Do you wanna eat my plane?' :))
[18:41:59] <andypugh> Not a gifted linguist then?
[18:42:16] <micges> rather not
[18:43:49] <skunkworks__> houston...
[18:44:12] <JT-Shop> I'd have to say that is more than I can say in French, Spanish and Portuguese... I do know a couple of words in each
[18:44:36] <skunkworks__> I can count to 20 in french
[18:44:44] <skunkworks__> maybe
[18:45:02] <JT-Shop> I can order 3 eggs and ask for my buddies steak to be well cooked in french
[18:45:44] <JT-Shop> turn off the water in Poruguese... count to 3 and say yo caro taco bell
[18:46:32] <JT-Shop> and my wife an the MIL both speak Spanish all the time...
[18:46:59] <JT-Shop> Sam how is the ... going?
[18:47:59] <skunkworks__> other than the flu... good.
[18:48:16] <skunkworks__> how about you? Internet still working?
[18:48:33] <micges> after 3 days in hungary I could say only one word: 'barlang' - cave
[18:49:30] <JT-Shop> yea, most bugs have been worked out of the satellite connection
[18:50:03] <djdelorie> my son just came back from a week in Italy. He said they all speak English over there. "You know, like spaghetti, lasagna, rigatoni..."
[18:50:29] <micges> heh
[18:50:36] <JT-Shop> in Italy they don't eat Italian food I here
[18:55:29] <Connor> so, my first question is, what do I need to do to read the input from the RPM sensor?
[18:56:03] <Connor> 2nd, how do I adjust the PWM output to compensate for the difference in target speed vs current speed ?
[18:56:23] <JT-Shop> RPM sensor?
[18:56:37] <micges> Connor: what rpm sensor? tick per rotation or encoder?
[18:56:49] <Connor> tick's per rotation.
[18:57:01] <Connor> I think it's like 16
[18:57:32] <JT-Shop> any of this have any merit? http://linuxcnc.org/docview/html/examples/spindle.html#_spindle_feedback_a_id_spindle_feedback_a
[18:58:04] <JT-Shop> micges: diving in the lake caves?
[18:59:30] <micges> no, man made caves
[18:59:48] <micges> I like caves and I'm afraid of diving
[18:59:56] <JT-Shop> just googled it and it looks like a nice place
[19:00:39] <micges> it's great
[19:03:13] <micges> Tihany, on biggest peninsula of balaton
[19:03:31] <JT-Shop> yea, I see it
[19:04:32] <JT-Shop> http://en.wikipedia.org/wiki/File:Tihanycivertanlegi3.jpg
[19:05:11] <JT-Shop> not a cheap place to buy a house
[19:06:08] <micges> Budapest is at least twice cheaper that this
[19:09:30] <micges> JT-Shop: http://www.panoramio.com/photo/11724027
[19:11:11] <JT-Shop> was it used as a defensive position sometime in the past?
[19:11:58] <micges> yes
[19:12:21] <micges> and also by monks
[19:12:36] <JT-Shop> we have some caves on a local river that was used as a hospital during the civil war
[19:16:49] <micges> I was thinking that your area is rather flat
[19:16:59] <Tom_itx> hilly
[19:17:05] <Tom_itx> my area is flat
[19:17:07] <Tom_itx> :)
[19:17:28] <jdhNC> I like caves, and diving, and diving in caves.
[19:17:51] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/psu/heatsink3.jpg
[19:17:59] <Tom_itx> got the end cut for mounting
[19:18:10] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/psu/driver_wiring.jpg
[19:18:15] <Tom_itx> and started a little wiring
[19:18:31] <jdhNC> connor: did you ever get a clean signal off the encoder input?
[19:19:25] <JT-Shop> micges: I'm located on the foothills of the Ozarks
[19:19:40] <JT-Shop> not too far away it is flat as a pancake
[19:20:38] <micges> I see
[19:20:44] <JT-Shop> http://maps.google.com/maps?hl=en&bav=on.2,or.r_gc.r_pw.r_qf.,cf.osb&biw=1101&bih=907&q=215+rugby+lane+poplar+bluff+mo&um=1&ie=UTF-8&hq=&hnear=0x87d7a38420207e21:0x2b21b8d501c14e33,215+Rugby+Ln,+Poplar+Bluff,+MO+63901&gl=us&ei=V3ugT6qWFKWyiQKUsu2dAg&sa=X&oi=geocode_result&ct=image&resnum=1&ved=0CB0Q8gEwAA
[19:21:37] <JT-Shop> zoom out and you can see where the flat ground starts to the south east of me
[19:21:52] <jdhNC> JT: any where near Lake Wappappello?
[19:22:35] <JT-Shop> yea it is 5 miles north, 5 miles east, 5 miles south, 5 miles east, 5 miles north from me
[19:22:43] <jdhNC> heh
[19:22:58] <Tom_itx> fun driving country
[19:22:59] <jdhNC> there is a diveable cave there, close to 300ft deep though
[19:23:08] <JT-Shop> ain't no straight way to get there sept by plane and then you can't land
[19:23:19] <JT-Shop> really what part?
[19:23:42] <jdhNC> it's called cannonball cave, but really Davidson Spring
[19:23:55] <jdhNC> http://www.caveatlas.com/systems/system.asp?ID=830&co=US
[19:25:08] <JT-Shop> ok, way up close to greenvillle bridge almost ... by chiona?
[19:25:55] <jdhNC> there is a map on the 'location' tab. looks like south of greenville
[19:26:02] <jdhNC> I think every place has a greenville
[19:26:08] <JT-Shop> lol
[19:26:42] <jdhNC> I forgot to click 'finish order' for my ACB's
[19:26:56] <jdhNC> that woudl explain why I never got tracking numbers
[19:27:49] <pfred1> we have a Greenwood
[19:28:03] <jdhNC> where?
[19:28:15] <JT-Shop> ok it is upriver from Chiona Landing
[19:29:04] <jdhNC> water is freezing thoug
[19:29:26] <JT-Shop> just below my favorite sand bar
[19:29:32] <JT-Shop> kinda hidden
[19:30:02] <JT-Shop> cool
[20:02:52] <Jymmmm> Yeah, every place has a Chiona Landing too ;)
[20:08:00] <pfred1> Chiona Landing is the new Main St.
[20:08:46] <Jymmmm> Actually,I think 2nd St is more commona as many pace rename "Main St" to something else.
[20:09:25] * pfred1 used to live about a mile from the Main St.
[20:09:44] <pfred1> they'd film commercials on it
[20:09:51] <Jymmmm> =)
[20:10:15] <pfred1> Main St. Chatham NJ
[20:10:40] <skunkworks__> I live on 2nd street -- 2 blocks up from main st
[20:12:38] <jdhNC> we have dock st, water st, front st, 2nd, 3rd, etc.
[20:13:05] <pfred1> jdhNC just a regular bunch of real creative minds huh?
[20:13:28] <jdhNC> yep, no main st, but the main street is Market St.
[20:26:16] <JT-Shop> say goodnight Gracie
[20:30:15] <pfred1> goodnight Gracie
[20:38:17] <andypugh> So, there I was, not reading, and you start talking about caves. Typical.
[20:38:43] <andypugh> (Caving has been a hobby of mine for decades, I used to cave about 3x a week)
[20:39:15] <jdhNC> that't a lot of caving
[20:39:20] <andypugh> (student training trip, fun trip and digging trip every week)
[20:39:29] <jdhNC> in your case, cold and wet I would presume.
[20:39:40] <andypugh> Not counting weekend trips :-)
[20:39:57] <andypugh> Indeed. All my hobbies involve cold and wet.
[20:40:07] <jdhNC> I make 5-8 'caving' trips a year
[20:40:19] <andypugh> caving / sailing / enduro riding / skiing.
[20:43:08] <andypugh> I really need to take up "sleeping"
[20:43:33] <jdhNC> plenty of time for that later.
[20:43:33] <pfred1> andypugh drill a hole in your roof and pray for rain
[20:44:22] <jdhNC> how much oversize do you bore a hole to fit a 3/8" shaft
[20:46:43] <andypugh> Press fit? Sliding fit? Running fit?
[20:47:05] <jdhNC> timing belt pulley on a motor shaft.
[20:47:11] <jdhNC> sliding?
[20:47:27] <andypugh> How is it clamped?
[20:47:46] <jdhNC> two set scews, 90degrees on the pulley, but just one flat on the shaft
[20:48:04] <andypugh> Eeew!
[20:48:52] <andypugh> I would say only use one screw, onto the flat.
[20:49:11] <andypugh> And bore half a thou oversize?
[20:49:22] <jdhNC> heh, I'm not that good.
[20:49:30] <jdhNC> I'll go for nominal and hope :)
[20:50:09] <jdhNC> one should read part dimensions before buying them.
[20:50:24] <andypugh> Just keep boring with no extra cut till it slides on. if it is in a lathe you can try the motor on without taking the pulley out of the chuck.
[20:50:54] <andypugh> For bonus credit bore the hole D-shaped to suit the shaft.
[20:51:20] <jdhNC> how does one do that? broach?
[20:51:26] <andypugh> CNC?
[20:51:49] <jdhNC> if I could cut metal, I wouldn't need to cut metal.
[20:52:23] <andypugh> Not a serious suggestion, sorry. But it is plausible: http://youtu.be/T4q8gCpeY1A
[20:53:53] <jdhNC> nifty.
[20:54:19] <andypugh> A way of getting a lot of torque from a D-shaped shaft (though sadly with high backlash) is to drill a second hole offset from the first and drop a fairly large diameter dowel in.
[20:55:05] <andypugh> I used that to drive some pinion shafts from windscreen wiper motors in my Robotwars robot.
[20:55:58] <andypugh> Partly because there was no access to the pinions for setscrews, and partly because I hate and distrust setscrews anyway)
[20:57:04] <andypugh> Right, sleep time.
[21:01:40] <Tom_itx> what is considered a good press fit on a 1/4" shaft?
[21:01:58] <Tom_itx> and how much expansion can i expect by heating the aluminum that will fit over the shaft?
[21:02:14] <Tom_itx> (and cooling the shaft)
[21:05:58] <pcw_home> aluminum is 12 uI/inch/deg F so boiling temp would get you 0.3 mills
[21:08:40] <pcw_home> (~130F over ambient) ~350 oven would get you ~double that
[21:08:51] <toastydeath> yeah, our alum oven was 400 f
[21:09:07] <toastydeath> for press fits
[21:10:01] <toastydeath> you'd have to look at the strain information for alum to get the friction, I don't know any of that offhand
[21:10:55] <pcw_home> got to do it fast or you heat up the shaft
[21:12:01] <pfred1> I use some aluminum flashing to keep my tablesaw fence from sliding
[21:12:14] <pfred1> makes all the difference over steel on steel let me tell you
[21:12:32] <jdhNC> I have some liquid He at work... would do wonders for cooling the shaft
[21:13:15] <pfred1> compared to steel aluminum slides like crap
[21:14:58] <Tom_itx> i've done it before with larger shafts
[21:15:54] <Tom_itx> ie timing gears on engines
[21:16:38] <pcw_home> Yeah a 1/4 shaft is going to heat up pretty fast (though aluminum has almost twice the coefficient of expansion of steel)
[21:16:52] <Tom_itx> i may set the hub on the hotplate and have the shaft cool and ready to go
[21:17:10] <Tom_itx> i'll have the depth i want it to slide pre set
[21:17:21] <Tom_itx> i know you only get one shot at it
[21:17:58] <pcw_home> You do want to get it right the first time...
[21:18:10] <Tom_itx> yeah or make a spare :)
[21:19:00] <Tom_itx> will 400F anneal the aluminum?
[21:19:05] <Tom_itx> it's T6 material
[21:19:27] <pcw_home> thats a Q for google
[21:19:34] <Tom_itx> heat treat isn't my strong suite
[21:19:51] <Tom_itx> i have a book i could check

[21:21:09] <gene__> Hi guys; I should report the the loss of a stack for mdi command I reported for my lathe setup, also is the same for the mill. No idea if that makes it easier or not, but since theres more mill than lathes, I expect it should make it easier to test.
[21:21:40] <Thetawaves> jdhNC, liquid he would be good if you could avoid condensate forming
[21:22:39] <jdhNC> it freezes
[21:23:10] <Connor> jdhNC: Sorry, was out playing with the machine.. I'm by passing the external display.. and have input into EMC...
[21:23:21] <Connor> Trying to understand the values it's returning.
[21:23:37] <Connor> this is just a basic counter.. no index.. 16 per reveolution.
[21:23:44] <Connor> what do I need to look at to get the RPM ?
[21:24:07] <Connor> I'm seeing the velocity like 7.28 etc etc.. way to low to be the RPM.
[21:24:26] <jdhNC> could be pulses per sec.
[21:24:33] <jdhNC> nah, too low
[21:24:47] <Connor> Well.. that was with it set for around 500.. so, that's close.
[21:25:10] <Connor> let me go throw a python component on to see.. brb
[21:25:41] <djdelorie> might be revolutions per *second*
[21:26:25] <gene__> Also, the wiki page, for the devel version, needs to specify those measurements that effect the thread depth, need to be entered in radius diffs, not diameters. Don't ask me how I know, but it just took me 2 hours to cut a great thread once I had a sharp tool because the diameter reduction was 2x intended, and it was only qadvanceing the bit about .0002 per pass. Duh.
[21:26:29] <jdhNC> could be anything, who knows what he set it for
[21:26:47] <djdelorie> MTBF in years ?
[21:27:02] <jdhNC> revs per micro-fortnights
[21:27:14] <gene__> Conner, I suspect that is RPS, it is here anyway. Multiply by 60 for rpms.
[21:27:29] <jdhNC> gene: what is that in metric
[21:27:46] <djdelorie> milliseconds per pulse works out about right; 500 rpm would be 7.5 mS if there's 16 pulses per rotation
[21:28:26] <gene__> revs & time aren't diff because its metric
[21:28:53] <jdhNC> 60 doesn't sound very metric. I think you shoudl use 100 seconds, or 1000 anyway.
[21:29:01] <pcw_home> 100 centiminutes
[21:29:13] <jdhNC> yeah, that's it.
[21:29:19] <djdelorie> 10 hours per day, 10 days per month, 10 months per year... I can retire a lot sooner that way!
[21:29:20] <gene__> RPS=revolutions per second.
[21:29:29] <toastydeath> sucks that timekeeping came from the babylonians
[21:29:38] <toastydeath> and they used a base 60 system for most of their mathematics
[21:29:49] <gene__> chuckle, must be getting late.
[21:30:17] <pcw_home> actually 60/12 is kind of nice we just have 2 few fingers
[21:30:28] <djdelorie> well, they had five fingers per hand, and twelve hands per committee...
[21:30:35] <jdhNC> I could use a few more fingers.
[21:30:40] <pfred1> at least the metric weenies haven't gotten to our clocks yet
[21:30:44] <jdhNC> or at least a gripping hand.
[21:30:52] <gene__> 10 isn't enough
[21:30:59] <Connor_CNC> okay. on my mill :)
[21:31:07] <jdhNC> rocking
[21:31:17] <djdelorie> we have milliseconds, microseconds, picoseconds... but not kiloseconds or megaseconds. Whew.
[21:31:53] <gene__> and don't forget nanoseconds :)
[21:32:19] <pfred1> that is the time Mork runs on
[21:32:28] <djdelorie> "Hurry up! We haven't got all second, you know!"
[21:32:41] <pfred1> nano nanu
[21:32:44] <Connor_CNC> okay, so how do I link a hal pin to a bar, * 60 ?
[21:33:06] <gene__> Gotta run, my back signed off 2 hours ago. Cheers, guys
[21:33:25] <pcw_home> man scale
[21:34:00] <pcw_home> nite gene__
[21:37:23] <jdhNC> pcw: the .invert_output on my pwm pin fixed the high-after-exiting problem. Thanks!
[21:38:37] <pcw_home> Yeah theres usually a way...
[21:39:04] <pcw_home> also correct for watchdog bite
[21:39:18] <jdhNC> the relays on the board still spaz when speed is set to 1, but that's a board issue I suppose.
[21:39:50] <Connor_CNC> addf scale.0 servo-thread
[21:39:50] <Connor_CNC> net scale.0.in <= spindle-velocity
[21:39:50] <Connor_CNC> setp scale.0.gain 60
[21:39:50] <Connor_CNC> setp current-spindle-speed <= scale.0.out
[21:40:10] <Connor_CNC> something not right.
[21:41:26] <jdhNC> is spindle-velocity right?
[21:46:16] <Connor_CNC> net spindle-speed-DAC scale.0.out => current-spindle-speed
[21:46:42] <Connor_CNC> Pin 'current-spindle-speed' does not exist
[21:47:57] <pcw_home> "net" creates a new net with the leftmost name
[21:48:42] <Connor_CNC> got it.
[21:48:55] <Connor_CNC> net spindle-speed-DAC scale.0.out => pyvcp.current-spindle-speed
[21:49:08] <jdhNC> Connor: did you finish the Z?
[21:49:12] <Connor_CNC> yup.
[21:49:22] <jdhNC> cool, mpegs?
[21:49:43] <Connor_CNC> later.. I'll upload to youtube soon.
[21:50:29] <jdhNC> make me some ballnut mounts :)
[21:55:40] <Connor_CNC> okay.. how do I get the abs for this.. I.E. loose the decimal place ?
[21:58:05] <djdelorie> Connor_CNC: if it's mSec/rot you need to divide, not multiply. Does the number go *up* if you slow down the spindle?
[21:58:31] <djdelorie> or does it show the right RPM yet?
[21:58:33] <Connor_CNC> djdelorie: I've got the right values now.. I just want to loose the decimal palce.
[21:59:00] <jdhNC> format the value in the pyvcp side?
[21:59:02] <Connor_CNC> wait.. not even that.. I want to smooth it out.. it's bouncing all ove rthe palce.
[21:59:32] <jdhNC> how far all over?
[22:01:35] <Connor_CNC> 10-30 rpm
[22:01:51] <pcw_home> lowpass?
[22:04:58] <Connor_CNC> It's not too bad using the meter widget
[22:13:14] <Connor_CNC> looks like it's within 8-9 % of commanded speed.
[22:13:19] <Connor_CNC> which is a bit too far out..
[22:14:11] <Connor_CNC> is their a way to use the command speed vs the RPM and have it adjust the PWM output ?
[22:18:14] <jdhNC> PID
[22:20:31] <mattwj2002> hi guys
[22:20:39] <mattwj2002> I need help please
[22:20:44] <mattwj2002> anyone here?
[22:20:51] <jdhNC> ask
[22:20:58] <jdhNC> connor: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Closed_Loop_Spindle_Speed_Control
[22:21:56] <mattwj2002> do you know of any open source 5 axis (or 6 axis) prebuilt cnc machines similar to the reprap prusa?
[22:22:43] <jdhNC> cnc? or 3d printers?
[22:22:49] <mattwj2002> cnc
[22:22:57] <mattwj2002> subtracting instead of adding
[22:23:38] <jdhNC> open source hardware?
[22:23:49] <mattwj2002> that would be nice if possible
[22:24:10] <jdhNC> just clarifying whatyou were asking. dunno of any of any sort.
[22:24:46] <mattwj2002> jdhNC: do you have a list of cnc machines?
[22:26:19] <jdhNC> just mine.
[22:27:29] <mattwj2002> ok
[23:42:09] <Connor_CNC> I keep runnign into issue were I need to access a pin, but, it's already tied to something else.. how can I attach to a pin already attached?
[23:43:12] <djdelorie> for reading?
[23:43:59] <Connor_CNC> yea.. I have some pid and pwm stuff setup.. I now to do link them to a py widgit pin
[23:44:48] <Connor_CNC> net pid_feedback pid.0.feedback <= motion.spindle-speed-in <= scale.0.out
[23:44:48] <Connor_CNC> net pid_command pid.0.command <= motion.spindle-speed-out => sum2.0.in0
[23:45:32] <Connor_CNC> need to grab scale.0.out and tie to
[23:45:35] <Connor_CNC> pyvcp.current-spindle-speed
[23:48:20] <Connor_CNC> for what ever reason, the custom_postgui.hal can't access the pid_feedback or pid_command nets ??
[23:48:21] <dgarr> net pid_feedback => pyvcp.current-spindle-speed
[23:52:12] <djdelorie> in my .hal, it does each connection on a separate line, search for both-home-x in http://www.delorie.com/cnc/dj_cnc_1.hal
