[03:23:24] <r00t4rd3d> Jymmm
[04:03:31] <r00t4rd3d> I blew my bicycle engine up last night. Lost a ring and it got caught up in my exhaust port, locked my piston right up.

[05:57:31] <DJ9DJ> lol
[05:58:11] <DJ9DJ> we have about 62 degree F here
[05:58:14] <DJ9DJ> right at the moment
[06:21:49] <paideia> can I convert a grayscale bitmap to 3d gcode?
[06:22:50] <paideia> like, using a grayscale bitmap to encode a relief-type of 3d structure and then generate the corresponding gcode?
[06:23:26] <r00t4rd3d> paideia,
http://microcarve.microcarve.biz/
[06:24:31] <paideia> r00t4rd3d, thanks for the suggestion but I was looking for an open source solution
[06:27:16] <Valen> theres a filter or something in EMC to do that
[06:29:53] <jthornton> paideia, image to gcode comes with linuxcnc
[06:30:34] <jthornton> paideia,
http://linuxcnc.org/docs/html/gui/image-to-gcode.html
[06:30:40] <paideia> jthornton, and it takes the intensity values to be the height values?
[06:31:06] <paideia> indeed
[06:31:11] <paideia> thanks!
[06:32:52] <jthornton> paideia, I've not used it, I just know it is there
[06:35:02] <paideia> interesting, the linuxcnc guys are using asciidoc for doc?
[06:35:15] <jthornton> yes, I am
[06:35:45] <paideia> :)
[06:37:02] <paideia> can I install this image2gcode without a linuxcnc?
[06:37:50] <jthornton> I would assume you can run it standalone
[06:40:49] <paideia> jthornton, would you know how I can download it?
[06:42:33] <jthornton> you might look in the linuxcnc wiki for it
[06:42:47] <jthornton> do you know where that is?
[06:44:03] <paideia> just googled it, got here so far,
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Cam
[06:44:21] <paideia> there is a link there about image-to-gcode but it's again only doc
[06:44:48] <paideia> there must be a place with the source code of all the programs shipped with linuxcnc
[06:45:32] <jthornton> yes, the git.linuxcnc.org I think is the url
[06:45:40] <paideia> indeed, just found it
[06:45:58] <paideia> but that way I don't think I can easily download only the program I'm interested in
[06:46:21] <jthornton> dunno I aways get the entire thing
[06:46:45] <jthornton> you could drill down and find it on the git web and copy and paste I assume
[06:47:08] <jthornton> http://git.linuxcnc.org/gitweb
[06:47:08] <paideia> I guess you're assuming it's a standalone script
[06:47:24] <paideia> if that's the case, indeed, let me see
[06:48:17] <jthornton> that's what I'm guessing yes
[06:50:48] <paideia> gosh.. I really need to learn git
[06:51:49] <jthornton> ok
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Git
[06:53:10] <paideia> thanks
[06:53:20] <paideia> going to study this a bit
[06:53:24] <jthornton> np
[07:12:01] <gmagno> hey, you know if I can run image to gcode (
http://www.linuxcnc.org/docs/2.4/html/gui_image-to-gcode.html) in a non linuxcnc os? Where can I donwload the scripts?
[07:14:05] <Valen> if you have an install of emc you could pull it out
[07:14:06] <Valen> i presume
[07:14:41] <gmagno> I have. Where should I find these scripts?
[07:16:50] <gmagno> I mean, the folder path
[07:18:30] <gmagno> hmm
[07:18:34] <gmagno> this is only one script
[07:18:46] <gmagno> it's in /usr/bin as it should of course
[07:44:32] <ReadError> i wish there was a tool to load gcode
[07:44:41] <ReadError> and do size measurements
[07:44:44] <ReadError> from point to point ;/
[07:44:51] <jdh> get a probe
[07:45:08] <jdh> how many dives this year?
[07:45:12] <jdh> <urk>
[07:46:07] <ReadError> jdh: a probe?
[07:46:10] <ReadError> i want to see it in the code
[07:46:22] <ReadError> so i can lay out my clamps and stuff properly
[07:46:31] <ReadError> i mean i could do it in the CAD program
[07:46:37] <ReadError> but when im in the basement i dont have all that
[07:47:54] <jdh> oh
[07:47:56] <jdh> nevermind.
[08:41:52] <gmagno_> I'm trying to run "image-to-gcode" python script on my laptop and I'm getting this error "ImportError: No module named rs274.author" what module is this??
[08:41:53] <gmagno_> :P
[08:49:00] <jdh> is your laptop running windows?
[08:57:50] <JT-Shop> from rs274.author import Gcode
[08:57:57] <JT-Shop> import rs274.options
[08:58:11] <JT-Shop> looks like you need a couple more files
[08:58:34] <cradek> that's part of linuxcnc, more or less
[08:58:52] <JT-Shop> ah ok
[08:59:19] <cradek> % dpkg -S rs274/author.py
[08:59:20] <cradek> linuxcnc-sim: /usr/share/pyshared/rs274/author.py
[09:01:25] <JT-Shop> ah found it lib/python/rs274/author.py
[09:01:29] <JT-Shop> thanks cradek
[09:02:41] <jdh> I have a livecd installed in a virtualbox on my windows computer
[09:08:16] <r00t4rd3d> that sounds pretty horrible.
[09:09:11] <jdh> the windows box?
[09:09:17] <r00t4rd3d> the setup
[09:09:31] <jdh> ^shrug^ works fine for the intended use.
[09:09:58] <jdh> I have another vbox loaded with XP for trying 'questionable' software.
[09:10:01] <r00t4rd3d> do a wubi install with the linuxcnc iso
[09:10:30] <r00t4rd3d> it will install ubuntu like a program
[09:10:30] <jdh> and reboot every time?
[09:11:13] <r00t4rd3d> what do you need windows for?
[09:11:27] <jdh> stuff
[09:11:30] <r00t4rd3d> lol
[09:11:51] <JT-Shop> same reason I have windoze on this computer
[09:12:22] <r00t4rd3d> jdh splurge on a intel atom d525
[09:12:39] <jdh> and 2 more monitors, another kb, another mouse?
[09:12:49] <r00t4rd3d> kvm switch
[09:14:23] <jdh> that's a lot of hardware to throw at a minor problem.
[09:15:05] <r00t4rd3d> i would not call having to run a lincnc in virtualbox minor.
[09:15:17] <r00t4rd3d> -a i guess
[09:15:22] <jdh> I don't have to, I can go look at one of my 3 linux boxes.
[09:16:00] <r00t4rd3d> now im just lost.
[09:16:11] <r00t4rd3d> CAN ANYONE HEAR ME?
[09:16:14] <jdh> or, I can just pop up the vbox where I am.
[09:16:33] <r00t4rd3d> are you doing simulations or something?
[09:16:39] <r00t4rd3d> or just messing around
[09:17:21] <r00t4rd3d> if you have 3 linux boxes why are you vbing it on windows ?
[09:17:44] <jdh> $d00d wanted to run image-to-gcode on his laptop. The error looks like he didn't have linuxcnc installed.
[09:18:31] <jdh> I have it because it is trivial and I have wanted to play with linuxcnc stuff while I was sitting at my winbox.
[09:22:56] <JT-Shop> jdh: I just typed image-to-gcode in a terminal on a computer with the livecd and it just works
[09:31:48] <jdh> JT: works for me too.. I assume his laptop is windows and he just copied image-to-gcode only.
[09:32:20] <jdh> which prompted my "I run linuxcnc-sim in a vbox on my winbox"
[09:33:13] <cradek> if in a virtual machine, linuxcnc-sim will work much better than the regular linuxcnc package
[09:34:13] <paideia> jdh, goncalao?
[09:34:27] <jdh> and a merry goncalao to you!
[09:34:37] <paideia> ok, you're not goncalao
[09:34:40] <paideia> :)
[09:34:55] <paideia> sorry, who asked the question about image-to-gcode?
[09:35:18] <micges> gmagno
[09:35:25] <paideia> ah ok
[09:35:41] <paideia> so I guess it's about the rs274.author module?
[09:36:22] * JT-Shop knew Andy would anwser that one :-)
[09:36:29] <paideia> I'm also trying to run image-to-gcode as a standalone
[09:36:38] <paideia> script
[09:36:45] <paideia> and I'm missing that dependency
[09:36:54] <paideia> is it easy to solve
[09:37:02] <JT-Shop> they are in the git
[09:37:27] <paideia> ok
[09:37:37] <jdh> or install linuxcnc-sim
[09:38:06] <paideia> might do that eventually, but right now just wanted to test that script
[09:38:12] <JT-Shop> paideia:
http://git.linuxcnc.org/gitweb?p=linuxcnc.git;a=tree;f=lib/python/rs274;h=953eee28845dd5e7c18f045c4ec0d46e5a59e674;hb=refs/heads/v2.5_branch
[09:38:47] <paideia> cool!
[09:38:51] <JT-Shop> btw, if you type image-to-gcode > myfile.ngc in the terminal the output goes to your file
[09:39:09] * JT-Shop goes back to work
[09:42:07] <Jymmm> JT-Shop: no nap?
[09:51:29] <JT-Shop> maybe later Jymmm
[09:51:38] <Jymmm> =)
[10:28:05] <gmagno> paideia, ramirao
[10:28:10] <gmagno> tou aqui
[10:30:06] <gmagno> paideia, ok those are good news from JT-Shop
[10:43:20] <r00t4rd3d> now back to my Family Guy carving.....
[10:56:15] <ReadError> new motor?

[11:48:04] <jthornton> Sweet! I finally got a working Glade3/Python framework up and running that I understand :-)
[11:49:06] <ReadError> Loetmichel: u still mess with the multirotors?

[12:20:22] <IchGuckLive> Hi all
[12:26:30] <skunkworks> http://www.youtube.com/watch?v=YSnNtgZrfyU
[12:31:22] <cradek> haha, xemc on a widescreen
[12:33:28] <cradek> that sure looks like a lot of work. I wonder if any of it is of use for the general population.
[12:34:39] <IchGuckLive> all homemade
[12:35:35] <IchGuckLive> 2.5.0
[12:35:42] <skunkworks> it looks like a conventional linuxcnc setup... (no offloading of motion)
[12:36:16] <skunkworks> just seems like a lot of work when atom+mesa 'just works'
[12:38:27] <cradek> aside from the work, I don't understand sacrificing the modern UI(s) in order to accomplish the goal of using a very low powered CPU - I don't see what the gain is in doing that
[12:38:53] <Jymmm> axis is a resource whore =)
[12:38:59] <cradek> maybe if you intended to build a very large number of them?
[12:39:28] <cradek> Jymmm: sure it is, mostly because of the preview, but so?
[12:40:07] <Jymmm> offload it to 2nd cpu/cores, and dedicate primary to the real work
[12:40:27] <Jymmm> and not the "fluff"
[12:40:48] <skunkworks> heh - which you can do with isolcups...
[12:40:49] <cradek> well that's exactly what you can get with our current scheme
[12:41:20] <cradek> (even though it's not really necessary with any old PIII or faster)
[12:41:23] <Jymmm> skunkworks: which I shouldn't even have to be aware of.
[12:41:39] <cradek> Jymmm: oh you're being that way again! I see.
[12:41:44] <skunkworks> then you should not be using linux ;)
[12:41:59] <cradek> Jymmm: you're a resource whore on this channel.
[12:42:08] <Jymmm> cradek: "that way"?
[12:44:52] <Jymmm> cradek: So, what way is that?
[12:54:31] <pcw_home> This is neat, I can talk to the Ethernet FPGA card from home
[12:55:41] <jdh> does it require a dedicated ethernet port?
[12:55:54] <pcw_home> For real time, yes
[12:57:05] <pcw_home> for regular utility stuff, no
[12:57:23] <IchGuckLive> i run 8hr a day on IBMA50 with no steploss at all
[12:57:42] <jdh> so you would need dual ethernet for that + regular tcpip
[12:57:47] <pcw_home> >01420001
[12:57:49] <pcw_home> > fecaaa55
[12:57:51] <pcw_home> not that exciting yet but that the HostMot2 cookie
[12:59:28] <micges> nice
[12:59:59] <pcw_home> >84420804
[13:00:01] <pcw_home> > c00100004d4553413749383010000000
[13:10:36] <JT-Shop> Sweet my Panasonic PLC programming software just added a PLC simulator so you can test code without being connected for the most part
[13:12:00] <jdh> nifty
[13:12:45] <pcw_home> how do you simulate external inputs? buttons?
[13:12:50] <jdh> I replaced a PLC cpu a few weeks ago, it was a newer faster rev, the faster sweep time screwed up some communications to 3rd party boards in teh backplane
[13:13:22] <JT-Shop> you can just click on the input and toggle the state
[13:13:25] <jdh> I override/toggle for simulation
[13:14:39] <JT-Shop> it does come with a warning about a few things like special timers and stuff but for general testing I don't have to take the PLC out of the smoker to test with
[13:17:52] <jdh> I have a spare plc at my desk for testing when needed. Works ok unless you need to test with weird io modules
[13:19:05] <JT-Shop> yea, the one I was doing via remote last week had a bar code scanner attached so could not test with that until I was live on the remote
[13:20:48] <r00t4rd3d> ReadError,

[13:20:52] <r00t4rd3d> im cutting atm

[13:47:05] <r00t-Shed> http://i.imgur.com/LNWa4.png
[13:47:06] <r00t-Shed> :)
[13:47:07] <cradek> Jymmm: sorry for being critical earlier. Sometimes it seems like the only time you pop out of lurk mode is to troll or when you're itching for a fight. I will try harder to assume good faith.
[13:48:09] <r00t-Shed> come out from under your foot bridge
[13:48:46] <Tom_itx> meh, Jymmm's just a troll
[13:49:39] <cradek> Tom_itx: I've known him a long time, and not always. maybe moreso lately. not sure what's up.
[13:49:55] <r00t-Shed> i think its bath salts
[13:49:57] <Jymmm> cradek: It's all good. I wasn't trying to troll, just aware that (as I call it) "fluff is a resource pig, and thinking that since emc doesn't (really) utilize multiple cpus/cores, that maybe the fluff could be offloaded to them, giving the 1ms timing described in the video better performance, and the fluff can do as it wants without interferance.
[13:51:21] <Jymmm> cradek: as far as Tom_itx goes, he's just trying to pull my chain is all (aka being funny)
[13:51:49] <cradek> you are mistaken about the facts of the matter: linuxcnc is multiple processes, and that means it uses multiple processors when they are available. you can even customize that usage. fluff/pig/etc is a matter of opinion and so I have no comment about that.
[13:52:21] <Tom_itx> cradek why are we urged to change the bios to one on the atom then?
[13:53:15] <cradek> that might be a case of hyperthreading? some people think that makes it worse. actual cores do help and you can even lock the realtime to just one of them, leaving the others free.
[13:53:21] <Tom_itx> yes
[13:53:31] <Jymmm> motion == work, everything else == fluff. the fluff *could* even be offloaded to a 2nd remote computer (which I've done and dramatically seen performance improvement on both sides of the coin)
[13:53:35] <Tom_itx> they recomended turning that off
[13:54:17] <cradek> my understanding is that hyperthreading is not multiple full cores, some parts of the CPU are shared, and that unsurprisingly turns out to hurt latency
[13:54:20] <Tom_itx> i think it gained a bit of performance but i don't think i'm loading it that much on mine anyway
[13:54:34] <cradek> I am not an expert on cpu technologies :-/
[13:54:38] <Jymmm> ... that's why I like keystick (less the lil quarks it has)
[13:54:44] <Tom_itx> i just do what i'm told
[13:54:49] <Jymmm> quirks
[13:54:51] <Tom_itx> unless i disagree and have good reason to
[13:55:11] <r00t-Shed> how hot do steppers normally get? hot to the touch?
[13:55:19] <Tom_itx> time to borrow a JT-Shop nap
[13:55:37] <cradek> r00t-Shed: you might be able to find a max temperature rating for your motors
[13:55:59] <Tom_itx> r00t-Shed since my driver / psu updates mine run rather cool
[13:56:02] <cradek> r00t-Shed: basic/dumb drives that don't chop can give you very warm motors
[13:56:05] <Tom_itx> prior to that they ran hot
[13:56:34] <Tom_itx> the gecko drives are right impressive in that regard
[13:57:10] <r00t-Shed> im guessing the tb6560 dont chop
[13:57:46] <Tom_itx> i dunno
[13:58:33] <r00t-Shed> my x axis is constantly moving and cool, my y axis is hardly moving and hot
[13:58:55] <cradek> it's normal for steppers to be hottest when not moving
[13:59:04] <cradek> they have the max current through them at that time
[13:59:25] <Tom_itx> the gecko has a 70% power reduction 1 sec after the last step pulse has been received. i attribute the 'coolness' partially to that
[14:01:34] <pcw_home> r00t-Shed: "im guessing the tb6560 dont chop"
[14:01:35] <pcw_home> They do (as do most step drivers) but you probably
[14:01:35] <pcw_home> do not have idle current reduction
[14:01:44] <cradek> looks like tb6560 is a bipolar chopper drive
[14:02:36] <r00t-Shed> would that be decay mode?
[14:03:21] <cradek> TQ1/TQ2 inputs seem like the current limit
[14:03:41] <r00t-Shed> pcw_home, how do I do that?
[14:04:14] <r00t-Shed> it is 95 out though too
[14:06:00] <pcw_home> if you have a separate input to lower the current you set it lower when not in motion
[14:06:40] <r00t-Shed> cradek, on the main page there is a blue box with xyz coordinates, what is that?
[14:07:04] <cradek> ?
[14:07:11] <r00t-Shed> http://www.linuxcnc.org/
[14:07:14] <Jymmm> tkemc?
[14:07:27] <Jymmm> or the other one I can't recall
[14:07:42] <cradek> oh right, that's (now known as) tklinuxcnc and is one of the previous generations of gui
[14:07:57] <r00t-Shed> oh
[14:07:57] <Jymmm> axis, tkemc, keystick, and ___________ ?
[14:08:07] <cradek> it's still in the distibution but doesn't really have a maintainer currently
[14:08:38] <r00t-Shed> where is the penguin code?
[14:08:55] <cradek> I think that's also in the distribution
[14:09:02] <cradek> it's called 3d_chips or similar
[14:09:10] <r00t-Shed> hmmmm
[14:09:29] <cradek> it's hard to cut: very plungey
[14:10:44] <r00t-Shed> i got some small balls
[14:10:57] <Jymmm> that's what she said

[14:42:49] <Loetmichel> sooo, 60 slot shields done... only 440 to go... $me is feeling a bit like Sisyphos ;-)
[14:49:30] <Jymmm> what is a "slot shield"?
[14:50:56] <jdh> outsource.
[14:59:09] <Loetmichel> Jymmm: the steel plates that cover the ends of Computer cards...
[14:59:53] <Loetmichel> i had to find a place to get 2 line-signals out of the computer... on 500 systems. The NIC seems to be the best place ;-)
[14:59:59] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=13438
[15:01:12] <Loetmichel> so i am modifying the 500 plats of the gbit nics on my private CNC mill... because the company has none
[15:02:19] <Jymmm> Loetmichel: Um, you can buy /get those free
[15:02:57] <Loetmichel> Jymmm: on a nic?
[15:03:14] <Loetmichel> there is no slot free to mount a plate with JUST the audio ports
[15:05:00] <Tom_itx> warranty void
[15:05:01] <Tom_itx> :D
[15:05:23] <Tom_itx> good idea though
[15:05:58] <Loetmichel> dell made a little mistake: we ordered systems with five plug-in-cards... 2 graphics boards, a fiber gbit nic, a copper gbit nic and a soundcard...
[15:06:03] <Jymmm> Loetmichel: Front panel three 1/8" holes?
[15:06:16] <Loetmichel> we got delivered systems with 4 slots and without a soundcard...
[15:07:11] <Loetmichel> so we will mount a usb soundcard inside.. but have to get the signals in/out
[15:07:17] <Loetmichel> times 500 ;-)
[15:07:24] <Jymmm> Loetmichel: they have those itty bitty sound cards
[15:07:43] <Tom_itx> i think he's settled on a solution already Jymmm
[15:08:38] <Jymmm> No, he has 8% of a solution and 446 more to go =)
[15:08:39] <Tom_itx> what did you use to engrave the graphic?
[15:08:43] <Tom_itx> heh
[15:09:14] <Tom_itx> might be easier to make a punch / die once then stamp em all
[15:09:19] <Loetmichel> Tom_itx: a engraving bit ;-)
[15:09:31] <Tom_itx> quicker
[15:09:35] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=8958
[15:09:58] <Loetmichel> Tom_itx: may be
[15:10:08] <Tom_itx> those look like carbide
[15:10:15] <Loetmichel> but i have no means of hardening a silver steel rod here
[15:10:22] <Loetmichel> they are carbide
[15:10:25] <Tom_itx> flame harden the edge
[15:10:33] <Loetmichel> and handmade from broken mill bits ;-)
[15:10:37] <Tom_itx> we did that on some dies we made
[15:10:39] <Tom_itx> heh
[15:10:41] <Tom_itx> good idea
[15:10:48] <Jymmm> Loetmichel: What, no wooden desks to burn?
[15:10:50] <Tom_itx> what color stone works on carbide? white?
[15:10:59] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=8961
[15:11:01] <Tom_itx> i need to find one
[15:11:01] <archivist> green
[15:11:03] <Loetmichel> diamond ;-)
[15:11:04] <Tom_itx> ahh ok
[15:11:12] <Tom_itx> i'm too cheap for diamonds
[15:11:34] <archivist> and not all greens are the same :)
[15:11:43] <Tom_itx> i don't doubt that a bit
[15:11:44] <Loetmichel> Tom_itx: these 20mm cutting discs cost about 10 eur for 10 pcs...
[15:11:59] <Tom_itx> i have some broken carbide bits is all...
[15:12:04] <Loetmichel> some?
[15:12:11] <Loetmichel> i have about a kg over here ;-)
[15:12:12] <Tom_itx> like 2 or 3
[15:13:06] <Tom_itx> ok, i need to get this spindle encoder mounted and figure out how to display it in axis / halui / glade
[15:13:09] <Tom_itx> something
[15:13:39] <Tom_itx> so i have a better idea of my cutting speed/feed ratio
[15:15:03] <archivist> looks near impossible for me to fit a spindle encoder on my hobbing machine where its really needed, the thing has a reduction right angle drive in the head
[15:16:12] <Jymmm> archivist pics?
[15:16:12] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/psu/encoder_disk2.jpg
[15:16:17] <Tom_itx> that's what i got so far
[15:16:57] <Tom_itx> http://tom-itx.dyndns.org:81/~webpage/cnc/psu/encoder_disk1.jpg
[15:17:10] <Tom_itx> yes i know the center hole is off a bit
[15:17:31] <Tom_itx> first time cutting with the new setup and i had the wrong tool in the tool list
[15:18:16] <Tom_itx> i used a last word on the diameter to align it
[15:18:49] <archivist> Jymmm, not mine but

[15:38:10] <Jymmm> archivist: couldn't you drill a small hole and install an optical pickup ?
[15:57:47] <jthornton> anyone want to read my Glade3 Tutorial?
[15:57:56] <Tom_itx> sure
[15:58:00] <jthornton> http://gnipsel.com/glade/index.html
[15:58:19] <Tom_itx> i'm considering it for my spindle monitor just to get into it a little
[15:58:39] <jthornton> this is basic glade3 python
[15:58:57] <Tom_itx> right
[15:59:15] <Tom_itx> i'll read it here in a bit.. gotta do something first
[15:59:33] <jthornton> it has helped me to learn the basics of glade3 and how the signals work with python so that should translate to GladeVCP
[16:00:12] <Tom_itx> is glade installed by default or do i need to get it?
[16:01:12] <Jymmm> jthornton: how are you generating the web pages you have?
[16:01:31] <jthornton> you can use the add menu thing to add it
[16:01:49] <jthornton> ok ubuntu software center thingsy
[16:01:54] <jthornton> asciidoc Jymmm
[16:02:07] <Jymmm> that has an editor?
[16:02:37] <jthornton> gedit
[16:02:53] <Jymmm> ah
[16:02:58] <Jymmm> and the photos?
[16:03:12] <jthornton> screen captures
[16:03:26] <Jymmm> but gedit allows insertion of them?
[16:04:09] <jthornton> the html files are created with asciidoc from a text file that is created in gedit
[16:04:25] <jthornton> you use an 'image' tag to add the image
[16:04:39] <jthornton> it's quite simple once you have done it a million times
[16:04:43] <Jymmm> jthornton: Right, but does gedit give you an option to embed the photos in the document you originally create?
[16:04:57] <Jymmm> pre-asciidoc
[16:04:59] <jthornton> dunno
[16:05:40] <jthornton> I have a makefile that does the magic
[16:06:00] <Jymmm> huh?? that doens't make sense? How are you creating the original gedit document, THEN telling it where and what photos to put where?
[16:07:09] <Jymmm> anyhow....
[16:07:50] <Jymmm> I want to thread some SS tubing, but how to you "clamp" it without crushing/maring it?
[16:08:18] <cradek> Jymmm: turn a bar that fits inside of it
[16:08:44] <Jymmm> cradek: ok, that tkes care of the crushing, what about marring it?
[16:08:50] <cradek> or just use a collet - they don't tend to crush tubes if the pressure is set right
[16:08:58] <Jymmm> ah
[16:09:00] <cradek> again, collet
[16:09:06] <cradek> how big?
[16:09:19] <Jymmm> 1/8 to 1/2"
[16:09:39] <andypugh> Cast a block of Woods metal round it, machine, melt off Woods metal.
[16:09:40] <Jymmm> (eventually nested)
[16:09:42] <cradek> for that size you could sure get 5c collets and a collet block
[16:11:49] <jthornton> Jymmm, the gedit document is a plain text file you use image::nameofimage.png[] to put an image into the html
[16:12:07] <jthornton> google asciidoc cheat sheet
[16:12:19] <Jymmm> jthornton: Do *YOU* do that from within gedit or afterwards?
[16:12:33] <jthornton> do what?
[16:12:51] <Jymmm> jthornton: insert images in your documents
[16:13:14] <andypugh> It's like writing html, you just put in a tag
[16:13:17] <jthornton> I type image::nameofimage.png[] where I want the image to be
[16:13:32] <Jymmm> jthornton: in gedit, or after gedit?
[16:13:46] <Jymmm> in your make fiel thingy
[16:14:06] <jthornton> the image::nameofimage.png[] just is part of the text in gedit
[16:14:32] <Jymmm> jthornton: ok, so you're manually inserting images into the gedit document. got it. thanks.
[16:15:25] <jthornton> no not really putting images in just the markup command
[16:15:26] <jthornton> http://pastebin.com/nNccbqW2
[16:16:09] <Jymmm> jthornton: yes I understand, I didn't mean/say embedding images, just inserting (the image tag) in the gedit document.
[16:16:41] <jthornton> yes, then asciidoc puts the proper tag into the html
[16:17:18] <rob_h> any one in UK want a hardinge HNC ? >>
http://www.ebay.co.uk/itm/HARDINGE-NC-LATHE-/150856673527?pt=UK_Home_Garden_PowerTools_SM&hash=item231fc228f7
[16:17:32] <Jymmm> jthornton: =)
[16:17:48] <cradek> are these HNCs breeding or what
[16:17:57] <jthornton> lol seems that way
[16:18:14] <Jymmm> factory shut down?
[16:18:33] <jthornton> well crap they won't mail it you have to pick it up
[16:18:34] <cradek> tape reader lit up and displays on - wonder if it actually works
[16:18:41] <rob_h> says it does
[16:18:56] <rob_h> hass a issue with an offset now and then it says if i rember
[16:19:05] <cradek> works *before* moving anyway
[16:19:16] <andypugh> Do they take an actual chuck, or are they collet only?
[16:19:24] <archivist> bah cant afford
[16:19:34] <cradek> you can get 5" chucks for them
[16:19:46] <archivist> looks nice condition too
[16:19:54] <rob_h> yea fairly common fitting on them
[16:19:55] <andypugh> I suspect I would have a bit of a hard time unloading at my end.
[16:20:05] <cradek> on top of the control is a place you're supposed to write the offsets so you can re-enter them when it forgets them. original factory equipment.
[16:20:31] <rob_h> on our CHNC and superslant we have power chuck for them.. they work off the closer
[16:20:33] <cradek> the top is full of D cell nicads and a battery charger
[16:21:06] <rob_h> if any one wants a spare cabnet we have one it used to work also
[16:21:07] <andypugh> If I bought it I would _have_ to scrap the original control just to fit it in my workshop.
[16:21:15] <Jymmm> andypugh: Not at all. you just need the Super JT Unloading System... For 300 easy paymants of $19.95 you will receive the complete system, Call now, operator standing by!
[16:21:16] <cradek> andypugh: the spindle's not supposed to be painted on the front...
[16:21:24] <rob_h> its apain in ass to program anyways
[16:21:37] <cradek> andypugh: the parts you actually want from the control are quite small
[16:22:12] <archivist> time to extend the workshop andypugh
[16:22:15] <andypugh> It has a crazy toolholder and no tailstock too, IIRC?
[16:22:24] <cradek> yes no tailstock
[16:22:32] <andypugh> I think I am talking myself out of it
[16:22:37] <cradek> the turret is pretty nice actually
[16:22:46] <jthornton> same tool holder as the CHNC I think
[16:22:47] <Jymmm> archivist: It fit in your angles corner backyard expansion =)
[16:22:52] <Jymmm> angled
[16:23:05] <archivist> simply no money
[16:23:15] <andypugh> Hmm, but my dad has a ton of space..
[16:23:17] <rob_h> depends on center high but yes u can swop the tooling
[16:23:54] <Jymmm> archivist: Well, the seller IS "StonerJeffery" and I see lots of grass in your area, I'm sure you could come to a trade =)
[16:24:05] <jthornton> I think they can be fitted with 1/2" or 3/8" or 10mm turret plates
[16:24:08] <andypugh> I have this NCbox needing something to control :-)
[16:24:26] <cradek> and we all know you love resolvers
[16:24:39] <rob_h> lo
[16:24:40] <archivist> Jymmm, what part of no money dont you understand
[16:24:44] <rob_h> plus 5C collets are cheap ;)
[16:24:45] <andypugh> Resolvers are much under-appreciated
[16:25:38] <Jymmm> archivist: (I meant barter, but it it was just a joke)
[16:25:59] <andypugh> WillemCMD as talking about an application needing 1/10000 of a turn positioning. Which sounds more like a job for a resolver than an encoder.
[16:26:00] <archivist> the joke wears exceedingly thin
[16:27:10] <andypugh> Talking of resolvers, these look like a bargain at the price:

[16:37:31] <Tom_itx> JT-Shop was it a 'how to make webpages' tutorial?
[16:37:56] <jthornton> no
[16:38:08] <Tom_itx> just catching up on the scroll :)
[16:38:12] <jthornton> glade3 python tutorial
[16:38:56] <jthornton> http://gnipsel.com/glade/index.html
[16:39:06] <Tom_itx> i'm looking at it
[16:39:23] <jthornton> do a refresh, I just added some content
[16:39:42] <Tom_itx> use this: © for your copywright
[16:40:06] <jthornton> ok
[16:41:09] <jthornton> Tom_itx, looks the same as (C)
[16:41:23] <andypugh> "copywright" sounds like a Chinese craftsman
[16:41:35] <Tom_itx> -w
[16:41:54] <Tom_itx> it should be the copyright symbol
[16:43:18] * jthornton goes back to the shop
[16:48:58] <Connor> andypugh: A Resolver ?
[16:49:28] <Tom_itx> JT-Shop looks good but i think i need glade to follow along
[16:49:43] <andypugh> I need more words to parse that into a question
[16:50:08] <Connor> Just looking at the item.. trying to figure out the difference between a resolver vs encoder...
[16:50:19] <Connor> not seen anyone talk much about resolvers...
[16:50:47] <andypugh> Well, it is actually rather a nice servo motor, which just happens to have resolver feedback.
[16:50:48] <JT-Shop> Tom_itx: you can add it from the Ubuntu Software Center on the main Ubuntu Menu
[16:51:22] <Connor> well.. that's what a servo is.. a motor with position feedback.. I get that.. It just happens to use a resolver instead of a encoder.
[16:51:34] <andypugh> Resolvers have theoretically infinite resolution, give absolute position feedback, and are immune to dirt and water. They are pretty tough too.
[16:51:49] <Tom_itx> JT-Shop i saw that. right now i need to find a pulley i lost
[16:52:03] <andypugh> On the down side, they are not at all easy to interface to digital systems.
[16:52:11] <JT-Shop> it's under the doo-dad
[16:53:03] <andypugh> You need to feed them a high-frequency sine wave on the primary terminals and measure the relative amplitudes of the two secondary signals.
[16:54:39] <Connor> I'm looking for a good servo unit that I can use for a 4th axis index/lathe
[16:55:34] <andypugh> Belt drive?
[16:55:51] <Connor> Haven't gotten that far yet.
[16:56:03] <Connor> If it's belt drive, I'll need to put a break on the spindle.
[16:56:10] <andypugh> Those might do, but are possibly slightly underpowered. And having just one Resolver on the machine might be awkward
[16:56:37] <Connor> It's AC.. and it's got the resolver.. so.. I don't think it's a good fit.
[16:57:23] <andypugh> No. It would suit my machine which already has 3 AC servos with resolvers. (and two brushless otors with encoders)
[16:57:42] <WillenCMD> so i got a keling digital stepper drive in today 8056D, it has a r232 port using an ethernet plug. Anyone built a cable for this, and messed with tuning the drive?
[16:57:55] <Connor> how do you convert the analog nature of the resolvers into digital?
[16:57:57] <andypugh> Though I am a cheap-skate and trying to use an Arduino for the Resolver position feedback
[16:58:13] <Connor> Ah. okay
[16:59:13] <andypugh> Connor:
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?ResolverToQuadratureConverter (But, actually, I am now sending absolute position via a serial link)
[16:59:33] <WillenCMD> is that fast enough to do pid?
[17:00:16] <andypugh> 1Mbps
[17:00:26] <andypugh> 12 bytes.
[17:00:32] <andypugh> Time will tell...
[17:00:44] <andypugh> Sorry, 6 bytes
[17:01:21] <andypugh> 10 bits of data sent as 3bits of header and 5 bits of data, so it can all be a bit non-synchronous.

[18:47:16] <JT-Shop> dang cast iron is nasty dirty to work with
[18:47:49] <r00t4rd3d> i got my classic usb nintendo controller working with linuxcnc to jog my all axis
[18:48:29] <Tom_itx> JT-Shop so is gunpowder but it doesn't seem to bother
[18:48:57] <andypugh> r00t4rd3d: Oddly tempting
[18:49:36] <r00t4rd3d> andypugh, 11 bucks
[18:49:36] <r00t4rd3d> http://www.ebay.com/itm/400304560914?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649
[18:50:23] <r00t4rd3d> then when im cutting i have nes emulator and play super mario bros
[18:50:54] <r00t4rd3d> or galaga
[18:51:58] <r00t4rd3d> so a smooth bore 3/8 couple wont tighten up on 3/8 rod
[18:52:44] <r00t4rd3d> i put a couple wraps of electrical tape on the end of the rod and that held for awhile.
[18:53:14] <JT-Shop> use duct tape, the real aluminum stuff not the other stuff
[18:53:27] <Jymmm> foil tape?
[18:53:32] <r00t4rd3d> tin tape
[18:54:21] <Jymmm> is there special dies for threading ss ?
[18:54:34] <Jymmm> or just use the typical ones?
[18:56:09] <r00t4rd3d> i tried to cut some ss the other day with a metal sawzall blade and it didnt even scratch it.
[18:56:47] <Jymmm> cut off wheel =)
[18:57:05] <r00t4rd3d> my buddy has a metal cutting chop saw, i used that
[18:57:11] <Tom_itx> Jymmm just make sure they're good dies
[18:57:16] <r00t4rd3d> basically a chop saw with a giant cut off wheel in it
[18:57:26] <andypugh> I normally use normal HSS dies, they work fine with SS
[18:57:50] <Jymmm> Tom_itx: I'm just going to buy a tap and die set as I need so many sizes and will only use it for this.
[18:58:23] <Tom_itx> i'm just saying i doubt a cheap chinese one would work that well
[18:59:01] <Jymmm> I'll hit the machinery shop here
[18:59:22] <Dew_> Hello
[18:59:27] <r00t4rd3d> ask for a tap, if they ask for what, tell them
[18:59:31] <r00t4rd3d> that ass
[18:59:45] <Jymmm> plus its such thin wall, I dont wanna screw em up =)
[19:00:30] <Jymmm> are there tapered dies?
[19:00:48] <Jymmm> nm
[19:00:49] <Tom_itx> pipe thread?
[19:00:50] <Tom_itx> yes
[19:00:56] <Tom_itx> lead in? yes
[19:01:14] <Jymmm> I need tapered taps, not dies.
[19:01:19] <Tom_itx> that too
[19:01:23] <Jymmm> cool
[19:01:23] <Tom_itx> for pipe thread?
[19:01:26] <Tom_itx> yes
[19:01:37] <Tom_itx> within reason
[19:01:39] <Jymmm> 1/8" - 1/2"
[19:01:43] <Tom_itx> yeah
[19:01:48] <Tom_itx> should be able to find them
[19:02:01] <Tom_itx> i've got a few 1/8"
[19:02:07] <Jymmm> cool, I'm making nested ss pole
[19:03:08] <Jymmm> gonna try using coupling nuts as the taper
[19:03:10] <Dew_> Does anyone here use FreeCAD to design before creating g codes? Just wondering what is your experience on this.
[19:03:45] <andypugh> I have tried it, but went back to familiar packages. It seems OK though.
[19:05:37] <Dew_> familiar packages?
[19:06:15] <r00t4rd3d> by package he means programs
[19:06:31] <Dew_> ah, i see
[19:07:21] <r00t4rd3d> blender is another one you can try. Not sure how to get from that to gcode though
[19:07:27] <Dew_> at my work I say scripts other guy says packages. He lives in another city. :)
[19:08:27] <andypugh> I have a free Autodesk Inventor license, and used to use it full-time as a job, so it's hard to change.
[19:09:05] <Dew_> I'm just starting to use FreeCAD and very little on linuxCNC. I'm planning on making a cnc router to use at home.
[19:09:10] <r00t4rd3d> autodesk is a nightmare
[19:09:33] <andypugh> Inventor is actually rather nice. I agree about AutoCAD
[19:09:53] <r00t4rd3d> oh
[19:10:07] <r00t4rd3d> i figured they renamed it
[19:10:28] <r00t4rd3d> years ago i tried that cad stuff
[19:10:44] <r00t4rd3d> they were sending me cds yearly
[19:11:13] <r00t4rd3d> they would go right in the garbage
[19:11:29] <Dew_> heh like AOL CDs?
[19:11:51] <r00t4rd3d> yeah
[19:13:08] <r00t4rd3d> andypugh, what format does that inventor save in?
[19:13:10] <JT-Shop> Dew_: you can use Qcad it's freeware and similar to acad
[19:13:13] <r00t4rd3d> stl dxf?
[19:13:52] <andypugh> Mainly their internal format, IPT, IDW, IAM.
[19:13:59] <JT-Shop> my favorite cam software is gedit
[19:14:02] <Dew_> I'm planning to hang around on irc to learn few things. Hope I can help out later. I haven't used IRC for about 11 years since I used to play UT99 alot.
[19:14:04] <andypugh> But it can export just about anything
[19:14:07] <r00t4rd3d> Ive have the most luck with LibreCAD
[19:14:36] <r00t4rd3d> have/had
[19:14:48] <Dew_> Can QCad and LibreCAD do 3D drawings?
[19:14:59] <r00t4rd3d> couldnt tell ya
[19:15:25] <JT-Shop> the freeware Qcad is 2-d
[19:15:43] <r00t4rd3d> 2.5d
[19:16:03] <JT-Shop> what kind of 3-d do you need?
[19:16:13] <r00t4rd3d> blender does 3d
[19:17:22] <andypugh> freeCAD does 3D, as does HeeksCAD
[19:17:24] <Dew_> Well I want to design a cnc router first in 3d model then eventually make some 3d parts.
[19:17:53] <andypugh> Alibre CAD is windows, and paid for, but does proper fully-working 3D
[19:18:15] <andypugh> Alibre for $99 is a decent buy if you can run Windows
[19:19:51] <Dew_> root- 2.5d?
[19:20:14] <Dew_> Maybe I ought to google that first :)
[19:20:36] <Dew_> The power of search engine
[19:21:16] <r00t4rd3d> most stuff you do on a cnc router is 2.5D, its not full 3d.
[19:21:22] <JT-Shop> here is a router that I working on in SolidWorks
http://imagebin.org/221204
[19:21:47] <JT-Shop> but I've changed it a lot since that photo
[19:22:10] <andypugh> You reminded me of a cartoon I saw, let me see if I can find it again:
http://www.free-power-point-templates.com/articles/wp-content/uploads/2011/12/i-have-powerpoint.jpg
[19:22:47] <Dew_> lol good one
[19:24:05] <Dew_> JT: that look good to start
[19:24:34] <Dew_> I'm going with v-groove bearings for x y z axis.
[19:25:58] <r00t4rd3d> start over
[19:27:46] <JT-Shop> v-groove bearings are expensive and some part is always scraping the ways
[19:28:43] <r00t4rd3d> Dew_, supported rails
[19:28:53] <JT-Shop> http://imagebin.org/221205
[19:29:38] <JT-Shop> http://imagebin.org/221206
[19:30:07] <r00t4rd3d> http://www.cncshop.com.au/images/SBR25S%20WM.JPG
[19:30:08] <Dew_> I already bought a set of them. :)
[19:30:14] <r00t4rd3d> aww
[19:31:47] <Dew_> How would v-groove scraping the ways? Does the bearing stop rolling and skid across the surface?
[19:31:54] <r00t4rd3d> yeah
[19:32:27] <Dew_> Now I can see that happening
[19:32:40] <JT-Shop> you have two flat surfaces that are not moving parallel to each other
[19:32:42] <r00t4rd3d> make sure you have a good dust collection system
[19:33:17] <JT-Shop> there will be some point that is moving equal to the movement and the rest will be skidding like dual tires on a truck
[19:33:24] <JT-Shop> during a turn
[19:34:50] <Dew_> I know skidding will not be good since it'll put a flat on some round surfaces.
[19:35:21] <r00t4rd3d> other people have used them with good results
[19:35:33] <Dew_> I guess I'll just have to keep an eye on them.
[19:35:47] <JT-Shop> they will work, so don't worry
[19:35:49] <r00t4rd3d> most people use some form of supported rails though, either homemade or bought.
[19:36:36] <JT-Shop> the photos of the router are a chap in Germany I think and he has good sucess with his design
[19:36:54] <JT-Shop> that's why I'm copying it :-)
[19:37:35] <r00t4rd3d> i would search for others who have used them and check out there designs
[19:37:43] <JT-Shop> I'm changing the rail supports to aluminum though
[19:38:27] * JT-Shop thinks he has the chef dey jour hat today
[19:38:27] <metal> whore!
[19:38:47] <JT-Shop> your making me dizzy now
[19:38:52] <Dew_> I saw the bearings setup in that image. Is there a place to adjust bearings to stay on contact?
[19:39:20] <JT-Shop> no, but I've been pondering if that is needed or not
[19:39:53] <r00t4rd3d> bigger holes and lock washers :)
[19:41:13] <Jymmm> JT-Shop: s/day/year/
[19:41:23] <Dew_> I would at least to make it adjustable. parts always wear down.
[19:41:24] <JT-Shop> my Rev 4 gantry design
http://imagebin.org/221208
[19:41:43] <r00t4rd3d> that seems like it would be top heavy
[19:42:02] <Jymmm> JT-Shop: purpose of covers?
[19:42:05] <JT-Shop> well it seems so without the rest of the machine
[19:42:09] <JT-Shop> what covers
[19:42:16] <Jymmm> top and botom of the box
[19:42:23] <JT-Shop> support
[19:42:27] <r00t4rd3d> beer rest
[19:42:33] <Jymmm> sawdust collectors
[19:42:46] <r00t4rd3d> lego collection
[19:42:49] <JT-Shop> well that too
[19:42:56] <Jymmm> lots and lots of sawdust
[19:43:04] <r00t4rd3d> i hate that shit
[19:43:14] <r00t4rd3d> but i hate listening to a shop vac even more
[19:43:41] <Dew_> put on a muffler :)
[19:43:45] <JT-Shop> they should put the DB's on the outside of the box in bolt letters for shop vacs
[19:44:09] <JT-Shop> I have one that is quiet and one that sounds like a turbo with a bad bearing...
[19:44:12] <Jymmm> remote dust collector in sound proof box
[19:44:21] * JT-Shop wanders inside
[19:44:31] <r00t4rd3d> i got a mini shop vac thats some what quiet but i cant find the hose.
[19:45:06] <r00t4rd3d> my normal one sounds like a cheeta getting anal raped by long dong silver.
[19:45:30] <Dew_> heh
[19:46:21] <Dew_> bbl
[20:51:37] <gmagno> hello, someone knows what module is nf in image-to-gcode python script?
[21:11:26] <gene77> Silly Q (maybe). I need to do a continue at the last size in a loooong loop, by creating a variable in the loop to save progress. But it doesn't exist when I hit reload, so is an error.
[21:11:37] <gene77> How can I fix that?
[21:12:44] <jdh> there might be a normal way for that, but I don't know what it is. I think you could store it in one of the coordinate offset locations maybe?
[21:13:44] <jdh> look in your config file directory for rs274ngc.var
[21:14:44] <jdh> hmm. or linuxcnc.var, or whatever is in your .ini file
[21:15:20] <Jymmm> Gimme a three digit int that seems/sounds larger than it really is?
[21:15:23] <bill1123> hi
[21:15:31] <bill1123> feature request for linuxcnc:
http://www.franksworkshop.com.au/CNC/MachPCBDrill/MachPCBDrill.htm
[21:16:14] <ReadError> *mach* = ban
[21:17:38] <jdh> that doesn't look like something that needs to be part of linuxcnc (IMO)
[21:17:52] <bill1123> its a great featre
[21:17:54] <bill1123> feature
[21:18:07] <Jymmm> Can't see the purpose of it anyway. emc can just mill the whole pcb, no need to etch.
[21:18:18] <jdh> of a cam/cad/pcb type program. It isn't controller specific
[21:18:53] <bill1123> basically it is just to allow for XY angle misalignment and to compensate for it, thats very useful
[21:19:59] <bill1123> like if doing double sided PCB's when you turn it over, that would make it easier to align
[21:21:42] <jdh> I've seen someone elses article that had the same problem, he loaded the artwork in photoshop/gimp/wtf first and pre-skewed it before printing
[21:22:00] <ReadError> can you drill a few holes
[21:22:04] <ReadError> to touch off from?
[21:22:28] <Jymmm> registration mark(s)
[21:22:35] <Jymmm> is what that's called
[21:22:57] <Jymmm> used in 4/6 color process printing
[21:23:35] <bill1123> some cnc machines might be "bent" too on one or more axis, so that could be corrected
[21:23:58] <gene77> Ok, I will try that on the ne4xt run
[21:24:12] <Jymmm> https://www.google.com/search?q=registration+mark
[21:26:22] <toastydeath> doesn't emc have error maps already
[21:26:30] <toastydeath> I could have sworn it does
[21:27:54] <toastydeath> bill1123, also, xyz are interrelated so that you can't have one static error map
[21:28:21] <toastydeath> a lot of controls have XYZ correction per axis
[21:28:48] <bill1123> so you can use an error map to correct XY misalignment?
[21:28:58] <toastydeath> i.e. a drill 6" long will drill in XY a different place than a 3" drill will
[21:29:06] <toastydeath> because the Z axis causes X/Y error to wander
[21:30:56] <toastydeath> still, I thought emc already had error correction
[21:33:46] <bill1123> maybe it does
[21:33:48] <bill1123> not sure
[21:36:42] <cpresser> bill1123: grecode can do that.
[21:37:49] <cpresser> use the overlay option. an on top of that, it only needs two points :)
[21:38:28] <toastydeath> if error correction only needs two points to function, your leadscrew pitch is off
[21:40:18] <cpresser> toastydeath: its no error correction! its just a simple tool to align/scale gcode
[21:40:40] <toastydeath> ah
[21:40:58] <toastydeath> i don't use emc/mach/etc, i am used to fanuc and mitsubishi controls - they both have scaling/alignment g-codes
[21:41:08] <toastydeath> as well as patterning/rotation
[21:42:12] <bill1123> cpresser: where is the overlay function?
[21:42:29] <bill1123> ah in gredcode i guess?
[21:42:37] <cpresser> bill1123: read? its in the help!?
[21:42:58] <bill1123> so grecode isnt required?
[21:43:11] <cpresser> help of grecode
[21:43:24] <cpresser> it does the same as the app in the link ("matrix transformation for points in the ideal design world, to the points in the real world")
[21:43:33] <cpresser> simple math
[21:43:47] <bill1123> ok sorry was confused, thought the overlay option was in linuxcnc
[21:43:50] <cpresser> http://code.google.com/p/grecode/
[21:43:54] <cpresser> nope. grecode
[21:44:13] <bill1123> ya im readnig it already :)
[21:45:28] <bill1123> thanks for the link
[22:41:29] <WiillenCMdesign> anyone care to double check my math on something
[22:44:34] <r00t4rd3d> 2+2=4
[23:01:37] <WiillenCMdesign> lol no checking to see if encoder count to rpms to latency is correct
[23:14:21] <r00t-Shed> http://i.imgur.com/ouTOZ.png
[23:14:35] <r00t-Shed> what i do while waiting for cuts :)
[23:33:10] <r00t-Shed> building shit from source to apply a 57kb patch really irritates me
[23:33:46] <r00t-Shed> stupid wine
