#emc | Logs for 2007-05-19

[03:02:57] <dmwaters> {global notice} Good day all! It's that time again, I've got 4 major rotation servers to upgrade. They've been out of rotation for a while so shouldn't be too noisey, but will cause some major disturbence as this effects the tor servers to. I will give further notice in wallops, so /mode your_nick +w if you are interested. Thank you for your patience, and thank you for using freenode!
[03:06:03] <Unit41> hmmm
[03:39:44] <Ziegler[out]_> hey all
[03:39:52] <Ziegler[out]_> Ziegler[out]_ is now known as Ziegler
[03:40:11] <Ziegler> things seem to be running ok on a 64 MB ram computer
[03:41:42] <Ziegler> need to slice off some of the extra fat that xubuntu uses.. but I think axis will work
[03:42:20] <Ziegler> anything in particular I should check on that low memory might cause a problem with?
[03:42:20] <Unit41> lol
[03:42:31] <Ziegler> :D
[03:42:47] <Unit41> use xfce or something
[03:42:56] <Ziegler> xubuntu already uses that
[03:43:12] <Unit41> aha
[03:43:20] <Ziegler> I think I might even strip that off and have xinit start emc2 directlu
[03:43:24] <Ziegler> directly*
[03:43:46] <Unit41> nice, but is it going to be fast enoug for RT ?
[03:43:56] <Ziegler> I dunno
[03:44:09] <Ziegler> thats the kernal I am using
[03:44:22] <Unit41> worth seeing anyway even if you gotta build a board to preprocess the gcode for the mill
[03:44:44] <Ziegler> I am using a hobby cnc board for a wood router
[03:44:58] <Ziegler> accepts step / direction
[03:45:26] <Ziegler> I need to run some latency tests yet.. but I will leave that for tomarrow
[03:45:31] <Unit41> I have bipolar pwm
[03:45:58] <Unit41> aliencnc on ebay
[03:46:12] <Ziegler> good purchase?
[03:46:16] <Unit41> its a great board for 100 bux
[03:46:24] <Unit41> 4 axis
[03:46:44] <Ziegler> this unipolar board I have is also 4 axis
[03:46:48] <Unit41> allegro chip
[03:47:00] <Unit41> a3977 iirc
[03:47:13] <Ziegler> that might be the same chip my board uses
[03:47:20] <Unit41> is it an mcp403 ?
[03:47:24] <Unit41> mc403
[03:47:43] <Unit41> thats another good ebay board
[03:48:30] <Ziegler> I really need to find another computer
[03:48:48] <Ziegler> damn think is only like 500 mhz 65 meg ram
[03:48:54] <Ziegler> 64*
[03:49:12] <Unit41> im in worse shape than you
[03:49:25] <Unit41> my only good computer for emc has a fried printer port
[03:49:26] <Ziegler> guy who dumped it on me said it was a p4 256
[03:49:39] <Ziegler> $15 at new egg will help ya there
[03:49:52] <Unit41> ??
[03:49:58] <Ziegler> get a pci card
[03:50:03] <Unit41> ah
[03:50:20] <Unit41> atm im running turbo cnc
[03:50:21] <Ziegler> when I first started playing with emc
[03:50:32] <Ziegler> I was going to build my own circuit
[03:50:39] <Ziegler> and let EMC do the indexing
[03:50:55] <Ziegler> for 4 axis.. I was going to need another para port
[03:51:25] <Unit41> in reality if you built a board to preprocess everything you would not even need realtime to do the milling
[03:51:47] <Ziegler> for sure
[03:51:50] <Ziegler> http://www.newegg.com/Product/ProductList.aspx?Submit=ENE&DEPA=0&Description=parallel+port&x=0&y=0
[03:52:27] <Ziegler> I am only about 75% complete with my router table
[03:52:36] <Ziegler> hehe.. looks like I just left

[03:55:32] <Unit41> cheaper on the bay
[03:56:06] <Unit41> I ended up getting the model lowe down without the gcode processor
[03:58:10] <Unit41> is it illegal to post shematics of commercial pcb's ?
[03:58:24] <Unit41> re stuff
[04:09:36] <Unit41> yep
[04:09:49] <Unit41> its only one driver portion of it anyway
[04:10:10] <chr0n1c> redesign the circut and make a new board?
[04:10:17] <chr0n1c> that does the same thing?
[04:10:24] <chr0n1c> move traces around n stuff?
[04:10:49] <Unit41> im deffinatly going to make something
[04:11:09] <Unit41> that allegro sollution is pretty decent though
[04:11:17] <Unit41> works on uni and bi
[04:12:57] <Unit41> http://www.students.tut.fi/~kontkant/a3977.php.html
[04:15:14] <chr0n1c> that's a nice page
[04:15:28] <Unit41> cept that one is wayy more complex than the aliencnc ones
[04:16:05] <Unit41> it only has one transistor per board
[04:17:13] <Unit41> I connected my stepper motors wrong and melted one axis completely
[04:17:36] <chr0n1c> oh my
[04:18:06] <Unit41> the guy I bought it from told me to send it back for a free replacement even
[04:18:34] <Unit41> wont even send it away
[04:18:41] <chr0n1c> is that your page unit 41?
[04:18:49] <chr0n1c> i'd like to see that eq prog
[04:18:55] <Unit41> not mine
[04:18:58] <chr0n1c> working on my pc*
[04:19:26] <Unit41> mine's over here www.cosmodio.net
[04:19:50] <chr0n1c> ohh
[04:20:27] <chr0n1c> nice header...
[04:21:00] <Unit41> some good recipe's in the forum
[04:51:34] <ds2> TGIF!
[04:52:05] <Unit41> TGFF
[04:54:19] <Unit41> are you doing it rite now ?
[05:08:28] <ds2> chilling
[09:02:09] <Rugludallur> morning
[10:20:54] <lerneaen_hydra> 'lo
[11:01:16] <Rugludallur> it's really nice to see the "limit" outlines in the 3d view in axis now

[11:29:09] <Rugludallur> hmm no idea what that is :P
[11:29:33] <chr0n1c> 1018 cold rolled (drawn) steel
[11:29:59] <Rugludallur> ahh ok
[11:30:19] <chr0n1c> they take hot roll and draw it through a finishing die after they blast the scale off
[11:30:31] <chr0n1c> and it comes out pretty and square

[12:07:53] <anonimasu> hi
[12:10:03] <chr0n1c> yo
[12:10:22] <chr0n1c> good morning
[12:10:35] <chr0n1c> (morning here)
[12:10:46] <anonimasu> it's afternoon here
[12:11:14] <chr0n1c> hmm.. where ya at?
[12:40:36] <Guest840> hi !
[13:37:48] <skunkworks> DanielFalck: how are you?
[13:39:07] <Ziegler> I got emc2 and axis working on a 450 mhz 64 MB machine last night... any potential issues besides latency I should check into?
[13:39:41] <CIA-8> 03jepler 07TRUNK * 10emc2/docs/src/gcode/main.lyx: strengthen the language against R-format arcs and give an example of 180 degree R-format arc badness

[13:40:54] <skunkworks> Ziegler: how did you do that? impressive. in my experience the live cd will not install on anything less than 256mb. people have mentioned that after the install they have removed the memory and it runs fine.
[13:41:07] <Ziegler> skunkworks: I installed xubuntu instead
[13:41:22] <skunkworks> ah - cool
[13:42:05] <Ziegler> I was trying to do it net-less last night.... but I got tired of screwing around, so I stuck a eth0 card in and got it done
[13:42:40] <Ziegler> Im still trying to stip off all the windows managers and the sort... so that startx just opens up emc
[13:43:10] <Ziegler> maybe I should just leave them on and make a custom xinit
[13:44:37] <Ziegler> 3 or 4 years ago I was playing with EMC on gentoo... but I dunno if I ever had the kernel right... or mabe real time support wasnt really supported back then
[13:44:56] <Ziegler> I look around at the wiki a bit... but is there any info on doing a non-debian install
[13:45:16] <Ziegler> about getting the kernel right?
[13:46:05] <skunkworks> * skunkworks is not a linux person. I know there is info on builing a kernel. you would have to look at the wiki page index.
[13:46:16] <Ziegler> ok cool
[13:48:43] <DanielFalck> skunkworks: I'm really getting into python programming these days
[13:49:16] <DanielFalck> I'm working on some things related to apt/vapt and cam
[13:49:28] <skunkworks> Very cool.
[13:52:28] <skunkworks> DanielFalck: I like your emc post on cnczone. <samco
[13:54:15] <DanielFalck> good. I haven't done much with emc lately,except install it on this computer and use sim mode. But, I will be using it again for some interesting things, hopefully soon
[13:54:48] <DanielFalck> I have been using it to check tool path with the apt/vapt cam stuff a lot lately
[13:55:04] <DanielFalck> using Axis
[13:55:22] <skunkworks> * skunkworks loves axis.
[13:57:32] <Ziegler> I sorta like it too
[13:57:35] <Ziegler> ;P
[13:58:01] <Ziegler> spent a few hours ago 2 or 3 weeks ago writting a small image-to-gcode program
[13:58:10] <Ziegler> got done and was going to test it in axis
[13:58:34] <Ziegler> to see the tool path... when I went to open the nc file... I noticed axis could open image formats too
[13:58:46] <Ziegler> hehe ... nice filter
[13:59:38] <Ziegler> oh well.. web-bassed image-to-gcode was still fun to work on
[14:03:19] <skunkworks> don
[14:03:23] <skunkworks> oops
[14:03:30] <skunkworks> don't you hate that ;)
[14:04:02] <DanielFalck> that return key is a bit close isn't it : )
[14:04:04] <Ziegler> I was very happy to see the feature... dont know how I missed it
[14:05:16] <skunkworks> I know I have said 'wouldn't it be nice if emc....' and someone comes back and says 'it does'
[14:05:23] <Ziegler> lol
[14:09:06] <Ziegler> im still trying to learn about how emc does probin
[14:09:10] <Ziegler> probing
[14:10:46] <skunkworks> http://www.linuxcnc.org/handbook/RS274NGC_3/RS274NGC_33a.html#1001097
[14:10:51] <Ziegler> I think I can rig up a small piezo with a switching transistor
[14:11:23] <Ziegler> solder a needle (probe) to the piezo...
[14:12:03] <Ziegler> when the piezo is moved from the needle... it can trigger the transistor
[14:13:29] <Ziegler> interesting skunkworks.. havnt come across that page yet
[14:14:02] <Ziegler> I knew about the 38.2
[14:14:45] <Ziegler> where do I get the program emcprobe?
[14:14:50] <Ziegler> or is that built in now
[14:16:55] <Ziegler> Im looking to probe more on the standpoint of scanning parts in
[14:27:58] <skunkworks> emcprobe was for emc1
[14:31:44] <Ziegler> ah... so its built in now?
[14:38:51] <DanielFalck> look at the file testprobe.ngc in the gcode examples directory that comes with emc2
[14:39:20] <DanielFalck> I think you can run it in sim mode and simulate a switch closure with hal
[14:39:39] <DanielFalck> I tried it out a month or so ago and it was nice
[14:40:40] <DanielFalck> it's in 'emc2/nc_files/gcode/
[16:31:41] <Ziegle1> Ziegle1 is now known as Ziegler
[16:57:12] <Jessxxxx> I know this is just a bit off topic, but is someone willing to field a g-code question?
[16:58:02] <Ziegler> I might be able to answer
[16:58:37] <Jessxxxx> I've got a bunch of x-y vectors that I want to repeat as a group, decrmenting z each iteration until a given number of loops have been performed.
[16:58:49] <Ziegler> sure
[16:58:54] <Jessxxxx> is there a simple looping method in g-code?
[16:58:57] <Ziegler> yup
[16:59:02] <Ziegler> one sec
[16:59:06] <Jessxxxx> *smiles*
[17:00:18] <Jessxxxx> btw, my pass height needs to stay consistent. just my cut depth will decrement.
[17:00:56] <Ziegler> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Oword
[17:01:10] <Ziegler> http://www.linuxcnc.org/handbook/gcode/g-code.html
[17:01:37] <Ziegler> let me open one of my program for a simple loop of code
[17:01:44] <Jessxxxx> i looked at the second link already. To be honest, I was boggled.
[17:01:53] <Ziegler> ok no problem
[17:02:14] <Jessxxxx> examples are great. that's how I learn.
[17:03:11] <NightHawk_Eng> Hi to all. I've got a problem installing EMC2 2.1.5 on a RTAI patched kernel
[17:03:15] <Jessxxxx> is "o" standard g-code, or something special for emc? I'm hoping to port my code
[17:03:30] <Ziegler> I dont think its just emc
[17:03:36] <Jessxxxx> k
[17:04:00] <Ziegler> look at this: http://pastebin.ca/497104
[17:04:17] <Jessxxxx> i'm there
[17:04:32] <Ziegler> o101 and 0100 are loops
[17:05:01] <Ziegler> I close them at lines 113 and 115
[17:05:29] <Ziegler> if you look at line 9 O101
[17:05:48] <Ziegler> I want it to loop while variable #4 is less than 3
[17:06:15] <Jessxxxx> ok... I think I get it.
[17:06:17] <Ziegler> line 112.. increments variable number 4
[17:06:26] <Ziegler> #4 = [#4+1]
[17:06:34] <Jessxxxx> icky variable names... Is that a g-code thing?
[17:06:39] <Ziegler> ya
[17:06:42] <Jessxxxx> blech
[17:07:02] <Ziegler> it starts the loop... runs the code... increments the varabile... runs the loops again... etc
[17:07:11] <Jessxxxx> so, just enclose their usages in square brackets?
[17:07:12] <Ziegler> you can now use those variables to control depth
[17:07:28] <Jessxxxx> I got it. Thanks ziegs...
[17:07:37] <Ziegler> I cant rember if the brackets are nessicary
[17:07:46] <Ziegler> necessary *
[17:07:55] <Jessxxxx> I'll give it a go. I might be back.
[17:07:58] <Jessxxxx> tyvm
[17:07:59] <Ziegler> cool
[17:24:01] <Jessxxxx> ziegs, one more? what's the g-code to re-reference all axes? g28 just seems to move to home. I want to move to home and re-zero everything.
[17:24:24] <Ziegler> oooohh... um
[17:25:36] <Ziegler> I cant remeber off hand... but I am looking
[17:25:43] <Jessxxxx> thx
[17:26:49] <Ziegler> http://linuxcnc.org/docs/2.1/html/gcode.html
[17:26:58] <Ziegler> g92 maybe?
[17:27:15] <Ziegler> or g10
[17:30:08] <Jessxxxx> those just seem to reset the logicals, not actually toggle the home switches.
[17:30:36] <Ziegler> can you re-explain what it is you are aiming for?
[17:30:55] <Jessxxxx> yes
[17:31:16] <Ziegler> G0 X0Y0Z0 will go home
[17:31:29] <Jessxxxx> to copensate for lost steps, I want to re-zero the machine after each loop
[17:31:45] <Ziegler> I see
[17:31:49] <Jessxxxx> but just moving to x0y0z0 wont accomplish that.
[17:31:56] <Ziegler> you are right
[17:32:03] <Jessxxxx> I need to actually toggle the home switches
[17:32:09] <Jessxxxx> and then re-zero
[17:32:10] <Jessxxxx> .
[17:32:20] <Ziegler> g28 doesnt do that?
[17:32:29] <Jessxxxx> it doesn't seem to.
[17:32:35] <Jessxxxx> it just moves to 0
[17:32:47] <Jessxxxx> the switches do get toggled
[17:32:50] <Jessxxxx> dont
[17:33:10] <Ziegler> what happens if you make the switches at like -1
[17:33:14] <Ziegler> and do a g28
[17:33:20] <alex_jon1> hi guys
[17:33:31] <Ziegler> (force the switches to trigger) Hi alex_joni
[17:33:49] <alex_jon1> hi Ziegler
[17:33:59] <alex_jon1> you related to Nichols?
[17:33:59] <Ziegler> alex_joni I have axis working on a 64 MB computer
[17:33:59] <Jessxxxx> (my machine "zeros" as it moves off the switch. so to zero, i need to pass over the switch and then move back off.
[17:34:05] <Jessxxxx> hi alex
[17:34:11] <Ziegler> no sorry alex_joni
[17:34:16] <alex_jon1> Ziegler: just kidding
[17:34:23] <alex_jon1> there's a method for tuning PIDs
[17:34:28] <alex_jon1> called Ziegler-Nichols
[17:34:32] <Ziegler> oh hehe
[17:35:13] <alex_jon1> let me kill my other personality
[17:35:15] <robin_sz> meep?
[17:35:46] <robin_sz> I finally have a machine to try EMC on ...
[17:35:47] <alex_jon1> are we well robin_sz ?
[17:35:52] <Ziegler> I dont know Jessxxxx... one of these other guys will
[17:35:52] <robin_sz> we are :)
[17:36:03] <alex_joni> glad to hear that
[17:36:17] <alex_jon1> alex_jon1 is now known as alex_joni
[17:36:18] <Jessxxxx> other guys? any ideas?
[17:36:35] <alex_joni> Jessxxxx: about what?
[17:36:39] <alex_joni> I missed the beginning
[17:36:49] <robin_sz> in the beginning ...
[17:36:52] <Ziegler> LOL
[17:36:53] <robin_sz> there was nothing
[17:37:05] <robin_sz> and then stuff arrived
[17:37:06] <Jessxxxx> i'm looking for a g-code that will re-reference all axes. not just move to zero.
[17:37:08] <Ziegler> he wants to move home and zero to make up for missing steps
[17:37:16] <alex_joni> Jessxxxx: there is no such g-code yet
[17:37:17] <robin_sz> a GCODE?
[17:37:24] <robin_sz> * robin_sz hoeps there wont be
[17:37:24] <alex_joni> Jessxxxx: BUT..
[17:37:25] <Jessxxxx> robin, is that like a divine UPS man?
[17:37:39] <alex_joni> you can always write a custom M-code, that will trigger homing using halui
[17:37:49] <Jessxxxx> ok.
[17:37:51] <Ziegler> hmm I wanna hear about this
[17:37:58] <Jessxxxx> thats what i needed to know!
[17:37:58] <alex_joni> Ziegler: about what?
[17:38:07] <Jessxxxx> ty vm
[17:38:12] <alex_joni> Jessxxxx: I suggest you read about halui
[17:38:17] <robin_sz> Jessxxxx, the normal way a machine (any machine) works is that the interpreter should be locked out of running a program until the axes have been zeroed
[17:38:18] <alex_joni> and HAL if you didn't already
[17:38:26] <robin_sz> otherwise ANYHTNIG could happen
[17:39:08] <NightHawk_Eng> Ehi guys, I've got a problem installing emc 2.1.5 from source
[17:39:18] <Jessxxxx> robin, I was gonna be looping a bunch, and I want to re-zero between iterations to compensate for lost steps.
[17:39:22] <alex_joni> NightHawk_Eng: go on
[17:39:27] <robin_sz> alex_joni, I now have a machine I can try emc on ... should be fun
[17:39:33] <robin_sz> alex_joni, 2 axes
[17:39:34] <NightHawk_Eng> the rtai_rtapi.c : 128 returns an error. negative value
[17:39:34] <alex_joni> robin_sz: indeed so
[17:39:44] <robin_sz> alex_joni, 2 axes, X and A
[17:39:48] <NightHawk_Eng> anyone know whar kind of problem is.
[17:39:49] <alex_joni> NightHawk_Eng: what distro?
[17:39:51] <alex_joni> what RTAI?
[17:39:55] <alex_joni> what compiler?
[17:39:58] <alex_joni> etc :)
[17:40:24] <NightHawk_Eng> Slackware 11, with kernel successfully patched with RTAI 3.5 Magma
[17:40:36] <robin_sz> Jessxxxx, the real answer is not to lose steps
[17:41:51] <robin_sz> alex_joni, I have a semi-auto non-ferrous saw I'm going to try and automate
[17:41:59] <Jessxxxx> *smiles at robin*
[17:42:24] <alex_joni> NightHawk_Eng: I heard about a couple of people having issues with 2.6.20
[17:42:25] <Jessxxxx> hun, I'm using steppers from old floppy drives. occassionally I lose steps!
[17:42:31] <alex_joni> but that mught be a different story
[17:42:40] <robin_sz> yeuuwww
[17:42:49] <alex_joni> (just in case if you get it running and it freezes, you know why)
[17:42:56] <Jessxxxx> (I'm cheap, but I'm not easy!)
[17:43:04] <alex_joni> but until then.. can you pastebin the last couple of lines from the build process?
[17:43:10] <robin_sz> Jessxxxx, yeah, Ive seen the photos
[17:43:20] <Jessxxxx> biatch!
[17:43:53] <Jessxxxx> well, thx for the help. I'm heading back to the shop.
[17:43:54] <Jessxxxx> ttys
[17:44:10] <alex_joni> Jessxxxx: np
[17:44:19] <NightHawk_Eng> alex-joni : gcc 3.4.6
[17:44:28] <alex_joni> can you pastebin the last couple of lines
[17:44:29] <alex_joni> from the build process?
[17:44:30] <Ziegler> alex_joni: I have emc2 installed on a 450 mhz 64 mb ram computer...
[17:44:37] <alex_joni> Ziegler: nice to hear that
[17:44:39] <Ziegler> what sort of things do I need to pay attention to
[17:44:43] <alex_joni> did you use the default install?
[17:44:45] <Ziegler> besideds latency
[17:44:52] <alex_joni> Ziegler: patience from the operator
[17:44:59] <alex_joni> *grin*
[17:45:13] <robin_sz> alex_joni, automatic saws are $$$ ... I got a small upstroker, with pneumatic clamping for reasonable money, going to try and add an X axis and *maybe* set the angle too
[17:45:19] <Ziegler> I couldnt alex_joni... I had to use xubuntu and stick a eth0 in the machine to do an online install of emc2
[17:45:36] <alex_joni> Ziegler: that barely counts as default install :D
[17:45:41] <alex_joni> but it still is ..
[17:45:43] <NightHawk_Eng> alex_joni : I've done the ./configure --enable-run-in-place && make clean && make %% make setuid
[17:45:48] <Ziegler> im still trying to strip the machine
[17:45:51] <alex_joni> sudo make setuid
[17:46:12] <Ziegler> but I think its at least usable now
[17:46:20] <NightHawk_Eng> alex_joni : the module hangs here : module_param(msg_level, int, S_IRUGO | S_IWUGO); -> line #128 of rtai_rtapi.c
[17:46:21] <alex_joni> Ziegler: nice
[17:46:35] <alex_joni> NightHawk_Eng: what's the exact error message?
[17:46:35] <NightHawk_Eng> alex_joni : it hangs just before the last command :)
[17:47:12] <NightHawk_Eng> I'll power on the pc and I'll tell you the exact error message
[17:47:14] <alex_joni> hangs how?
[17:47:23] <alex_joni> ok, I'll wait
[17:47:27] <NightHawk_Eng> please wait 5 min
[17:47:31] <NightHawk_Eng> many thanx!
[17:48:16] <NightHawk_Eng> I've got the pc with linux on another floor! :)
[17:50:42] <alex_joni> no problem
[17:53:09] <NightHawk_Eng> the make command is running now. I'm waiting for the error message
[17:53:19] <chr0n1c> well, i sold my psp on ebay... so i can buy some aewsome steppers for the hobbycnc board... keling.com the best place still?
[17:53:35] <chr0n1c> awesome steppers*
[17:54:17] <Ziegler> they more expensive from hobbycnc?
[17:54:52] <Ziegler> what is keling.com?
[17:55:19] <chr0n1c> http://www.kelinginc.net
[17:55:37] <chr0n1c> i had the wrong addy in m head
[17:55:39] <Ziegler> http://www.kelinginc.net/
[17:55:44] <Ziegler> hehe just found it
[17:56:30] <chr0n1c> hey so tommorrow is my birthday...
[17:56:36] <Ziegler> I got a hobbycnc board with the steppers
[17:56:42] <chr0n1c> yay me.. 28, another year down the drain!
[17:56:56] <chr0n1c> i only bought the diy solder 4 axis board
[17:57:45] <Ziegler> http://images.myonlinesite.com/cnc/log.html
[17:57:54] <Ziegler> thats what I am working on
[17:58:07] <NightHawk_Eng> alex_joni : OK, here you are the exact error:
[17:58:11] <chr0n1c> i read that.. nice writeup
[17:58:45] <Ziegler> lots of grammar errors and spelling problems...
[17:58:50] <Ziegler> but it helps me keep track
[17:59:12] <chr0n1c> my html editor has a spell check.. i try to remember to use it
[17:59:22] <jepler> chr0n1c: happy birthday
[17:59:28] <chr0n1c> i didn't notice any big errors
[17:59:33] <chr0n1c> ty jep!
[18:00:01] <chr0n1c> ler
[18:00:04] <Ziegler> * Ziegler should get a spell checker for his text editor
[18:00:25] <chr0n1c> lol, what do you use to code the site Ziegler?
[18:00:32] <Ziegler> vim
[18:00:35] <chr0n1c> ohh..
[18:00:46] <chr0n1c> i use coffeecup (for windows)
[18:00:56] <Ziegler> Ive used that... long time ago
[18:01:02] <chr0n1c> it works the same way my brain does when i am coding html
[18:01:03] <NightHawk_Eng> alex_joni : /CNC/emc2/src/rtapi/rtai_rtapi.c:128 :error : size of array 'type name' is negative
[18:01:19] <NightHawk_Eng> it quits the directory and returns to prompt
[18:01:46] <Ziegler> been using kate a bit more... makes ftp updates to the site a bit easier
[18:02:06] <chr0n1c> coreftp
[18:02:15] <chr0n1c> .. what i use to uplaod pages
[18:02:18] <Ziegler> that a text editor?
[18:02:21] <chr0n1c> upload
[18:02:27] <Ziegler> or just ftp
[18:02:29] <chr0n1c> it's an ftp client
[18:02:39] <chr0n1c> free.. works great for basic ftp stuff
[18:02:58] <Ziegler> kate... I can hit the save button and it uploads the text to the website.... I bet I can install a spell checker for it
[18:03:19] <alex_joni> NightHawk_Eng: strange.. let me check
[18:03:21] <alex_joni> 2.1.5 you said?
[18:03:25] <chr0n1c> yup i think i have seen one when doing one of the many linux installs
[18:03:45] <NightHawk_Eng> yes 2.1.5
[18:04:21] <jepler> NightHawk_Eng: are you using linux 2.6.12-magma, or some other version?
[18:04:29] <Ziegler> I really need to hit the hardware store to pickup some more materials for my gantry
[18:04:33] <NightHawk_Eng> alex_joni : the line where it hangs i think is here "module_param(msg_level, int, S_IRUGO | S_IWUGO);"
[18:04:40] <alex_joni> jepler: with 3.5 magma
[18:05:11] <chr0n1c> lunchtime! see ya at mcd's
[18:06:06] <jepler> probably something changed in the kernel headers between 2.6.12-magma and this version -- you should troubleshoot.
[18:06:50] <alex_joni> NightHawk_Eng: I looked at 2.6.17 and both S_IRUGO and S_IWUGO are positive numbers
[18:06:51] <NightHawk_Eng> Chr0n1c : in italy is 8_00PM dinner time!!!
[18:07:11] <alex_joni> NightHawk_Eng: can you look at linux/source/include/linux/stat.h ?
[18:07:23] <NightHawk_Eng> of course
[18:07:24] <alex_joni> and tell me what numbers you see there (around line 50-60)
[18:07:36] <NightHawk_Eng> wait the floor time :)
[18:07:39] <jepler> I'd try getting rid of the #ifdefs there and use RTAPI_MP_INT which "should" work regardless of kernel version.
[18:09:43] <alex_joni> hmm.. they didn't change
[18:10:17] <alex_joni> might be compiler related
[18:10:32] <alex_joni> gcc 3.4.6 as NightHawk_Eng reported
[18:10:57] <jepler> ah, well who knows..
[18:11:15] <jepler> * jepler wanders off
[18:12:44] <alex_joni> NightHawk_Eng: can you try to replace RTAPI_MSG_INFO with 3 a few lines above?
[18:13:19] <alex_joni> in rtai_rtapi.c line 123
[18:13:43] <NightHawk_Eng> hey guys. I'm not a code guru as you but I've foune the S_IRUGO and S_IWUGO commented with # a no number related under stat.h
[18:14:08] <NightHawk_Eng> ok I'll try to replace the line
[18:14:18] <alex_joni> they are defined there by |-ing together some other stuff
[18:14:29] <alex_joni> but I don't think the error message comes from that
[18:14:30] <jepler> In C, a line beginning "#" is not a comment
[18:15:10] <NightHawk_Eng> jepler : I'm embarassed :(
[18:15:10] <JymmmEMC> #include stdio.h
[18:15:19] <ds2> uh
[18:15:21] <alex_joni> 20:53 < NightHawk_Eng> alex_joni : /CNC/emc2/src/rtapi/rtai_rtapi.c:128 :error
[18:15:22] <alex_joni> : size of array 'type name' is negative
[18:15:30] <alex_joni> the error is really strange
[18:15:33] <ds2> hey Jymmm, you going to the maker faire?
[18:15:48] <JymmmEMC> ds2: is that today?
[18:15:50] <alex_joni> as the code on line 128 is module_param not module_param_array
[18:16:13] <ds2> Jymmm: yes, and tomorrow
[18:16:32] <JymmmEMC> ds2: Damn... very doubtful =(
[18:17:07] <ds2> i might go up there
[18:17:29] <NightHawk_Eng> RTAPI_MSG_INFO modified with 3. I'll give make to see what happens
[18:17:31] <NightHawk_Eng> ?
[18:17:37] <alex_joni> NightHawk_Eng: yeah
[18:20:10] <NightHawk_Eng> done. waiting the critical point
[18:21:14] <JymmmEMC> http://makerfaire.com/pub/e/83
[18:21:23] <jepler> after changing one source file, you should be able to just type "make", not start all over again from configure. it should take a few seconds to test these changes.
[18:23:19] <NightHawk_Eng> nothing
[18:23:24] <NightHawk_Eng> the problem remains
[18:23:43] <NightHawk_Eng> jepler : I've sent make clean before make
[18:23:49] <jepler> no need for that either
[18:24:18] <NightHawk_Eng> the RTAI runs ok and the system is stable
[18:24:33] <NightHawk_Eng> latency is about 100000ns in kernel mode
[18:28:28] <NightHawk_Eng> Why I didn't study the C language!!! :)
[18:28:34] <NightHawk_Eng> ?!?!?!?!
[18:39:25] <alex_joni> NightHawk_Eng: odd
[18:41:26] <alex_joni> NightHawk_Eng: is this a 64-bit system?
[18:42:41] <Unit41> running 32 bit linux ?
[18:42:57] <Unit41> that live ubuntu emc will not even boot on 64 bit
[18:43:24] <Unit41> and emc seems to not wantto compile on suse 64
[18:43:48] <chr0n1c> the maker faire explains why the internet is so dead today...
[18:43:54] <chr0n1c> all the people are there!
[18:44:20] <Unit41> lol
[18:45:11] <Unit41> does most of the population actually use computers nowdays ?
[18:45:37] <chr0n1c> i'd say it's close to 50/50 in the us
[18:45:42] <chr0n1c> US
[18:46:12] <chr0n1c> at least that many people are on myspace... maybe they share computers
[18:46:49] <chr0n1c> every school has a computer class i can imagine
[18:47:21] <Unit41> the army of youth
[18:47:40] <Unit41> were all part of it
[18:47:44] <NightHawk_Eng> alex_joni : no is a 32bit system. Vanilla kernel patched with RTAI 3.5
[18:47:44] <Unit41> huhu
[18:48:10] <chr0n1c> * chr0n1c is a no-limit soldier, part of the hip-hop army
[18:48:44] <chr0n1c> uh.. j/k i'm no soldier, just a punk...
[18:49:08] <NightHawk_Eng> alex_joni : what is your local time?
[18:49:22] <Unit41> bulls on peraid
[18:49:38] <chr0n1c> that's a good song...
[18:49:59] <chr0n1c> i haven't listend to rage ina long time, i been listening to my own music...
[18:50:31] <Unit41> what the genere
[18:50:45] <Ziegler> is there a way in axis to edit the gerber without reloading it?
[18:50:53] <chr0n1c> http://noth1ng.com
[18:50:58] <chr0n1c> it's um.. crazy
[18:51:00] <chr0n1c> that's what it is
[18:51:06] <Unit41> I dabble too
[18:51:18] <Unit41> been getting ardour and lmms setup
[18:51:24] <Unit41> lmms seems hopeless
[18:51:25] <chr0n1c> it's industrialish/hip-hopish
[18:52:09] <alex_joni> NightHawk_Eng: 21:41 < NightHawk_Eng> alex_joni : what is your local time?
[18:52:15] <chr0n1c> i use reason and battery and record the output live with cooledit.. it's all running through a numark em360 mixer (with a kaoss pad) then back to the pc for recording
[18:52:25] <chr0n1c> sometimes fruity loops*
[18:52:32] <chr0n1c> i don't reall yplay any real instruments
[18:52:38] <Unit41> jesus that stuff is crazy
[18:52:45] <chr0n1c> thanks!
[18:52:59] <chr0n1c> we make random beats and skratch records to it...
[18:53:05] <Ziegler> got a question about axis...
[18:53:17] <Ziegler> last night I was able to open png files...
[18:53:20] <Ziegler> and jpegs
[18:53:25] <Ziegler> now that option isnt there
[18:53:44] <Ziegler> only gives me ngc
[18:54:48] <Unit41> that actually hurts my head to listen to
[18:54:52] <Ziegler> does that part of the app depend on something else?
[18:55:01] <Ziegler> like gdm?
[18:55:45] <alex_joni> Ziegler: no, it depends on the ini
[18:55:59] <alex_joni> there is some special stuff that defines filters in the ini
[18:56:05] <alex_joni> look at sim/axis.ini
[18:56:08] <alex_joni> under [DISPLAY]
[18:56:11] <Ziegler> hmm.. maybe I opened sim by accident last night
[18:56:19] <alex_joni> I'm sure you did
[18:56:25] <Ziegler> danke
[18:56:35] <Ziegler> also... is there a way to edit gerber in axis...
[18:56:40] <Ziegler> or do you still need to reload it
[18:56:47] <Unit41> i'll scratch mix is cool
[18:56:56] <alex_joni> Ziegler: you need to reload it
[18:57:01] <Ziegler> shucks
[18:57:07] <alex_joni> it'
[18:57:10] <Ziegler> thanks
[18:57:15] <alex_joni> it's quite easy
[18:57:30] <Ziegler> ya... just means I need a text editor open now too
[18:57:34] <alex_joni> there's a keyb shortcut for that :P
[18:57:39] <Ziegler> oh yeah?
[18:57:46] <Ziegler> and that is...
[18:57:50] <alex_joni> Ctrl-something
[18:57:53] <Ziegler> LOL
[18:57:56] <alex_joni> look under help
[18:58:23] <Unit41> thefunkinchr0nic
[18:59:09] <chr0n1c> thanks Ziegler
[18:59:16] <Ziegler> for?
[18:59:25] <chr0n1c> thanks for listening... and the compliments
[18:59:42] <Ziegler> 0_o?
[18:59:48] <Ziegler> ahh.. havnt gotten to yet
[18:59:51] <Ziegler> but I will
[18:59:56] <Ziegler> (very interested)
[19:00:15] <alex_joni> * alex_joni wants to listen too
[19:01:23] <chr0n1c> i find it random places
[19:01:36] <Ziegler> still cant find the "edit" button
[19:01:36] <chr0n1c> alex_joni: http://noth1ng.com
[19:02:43] <alex_joni> may I say it's odd?
[19:02:46] <Ziegler> reminds me a bit of primus
[19:03:37] <Ziegler> um maybe not
[19:03:39] <Ziegler> LOL
[19:03:46] <Ziegler> very cool tho
[19:03:50] <Unit41> who the hell would buy a demo disk for 8 bux chr0n1c ?
[19:04:10] <Ziegler> like how thick it is
[19:04:13] <Unit41> on your ebay store for console games
[19:04:16] <Ziegler> not much dead space
[19:05:45] <Ziegler> ctrl+r reloads .. what brings up the editor?
[19:06:11] <chr0n1c> yes, you may alex_joni
[19:06:16] <chr0n1c> i agree it is odd
[19:06:31] <chr0n1c> i just sold a loco roco demo today for 11.33
[19:06:34] <chr0n1c> no kidding
[19:08:03] <chr0n1c> people who collect game stuff and people who can't get to the stores to get free demo''s buy them i guess
[19:08:33] <chr0n1c> or someone who is thinking about buying the real game and doesn't want to spen 50 bux and decide they dont like it?
[19:08:54] <alex_joni> chr0n1c: I changed my impression of it
[19:08:59] <alex_joni> it's interesting
[19:09:11] <chr0n1c> cool, it's not something you can just hop in to
[19:09:21] <chr0n1c> like tequila, it's an aquired taste ;)
[19:10:33] <chr0n1c> not too many people have heard it.. the few who stumble on my site.. and some people on myspace..
[19:10:56] <chr0n1c> it started as me and a few buddies playing around with reason... and it was fun so i actually bought some equipment
[19:11:26] <chr0n1c> i need a singer/rapper/lyricist for it and i think we'll have something neat
[19:12:02] <jmkasunich> http://jmkasunich.dyndns.org/pics/lufkin-jig-bore-mics.jpg
[19:12:27] <jmkasunich> newest addition to my shop ^^^^^ $25!
[19:12:45] <Skullworks_PGAB> ebay?
[19:12:47] <chr0n1c> that'sa sexy set of tools there jmkasunich
[19:12:51] <jmkasunich> HGR surplus
[19:13:40] <jmkasunich> the bars would let me go from 0 to 34" in 1" increments
[19:13:50] <jmkasunich> just the thing for making up lead screw error comp tables
[19:14:06] <chr0n1c> only 34", lol
[19:14:17] <chr0n1c> my mics only go to 1
[19:15:31] <jmkasunich> I gotta make a trough for them, with a dial indicator mounted at one end
[19:15:44] <jmkasunich> I'm pretty sure I have a 0.0001 indicator around here
[19:16:08] <Skullworks_PGAB> Making wood cases for some of my tool "scores" is what I will do as my first projects as a learning tool for becoming an EMC operator...
[19:16:09] <chr0n1c> so you can tell your closing pressure?
[19:16:18] <alex_joni> hi jmkasunich
[19:16:30] <jmkasunich> chr0n1c: no, so I can use them to check machines
[19:16:52] <jmkasunich> you have a dial indicator at one end of the trough, clamp the trough and indicator mounting block to the table
[19:16:52] <chr0n1c> i c
[19:17:01] <jmkasunich> put a dowel pin in the machine spindle
[19:17:20] <jmkasunich> jog the machine carefully until the pin touches the indicator, take a reading
[19:17:45] <jmkasunich> then move the machine 1" away, insert a 1" calibrated rod in the trough, jog against the end of the rod, take a reading
[19:17:52] <jmkasunich> repeat with 2", 3", etc rods
[19:18:44] <chr0n1c> then you can chart out the backlash...
[19:18:44] <Skullworks_PGAB> fun part is keeping the stack under micro tension so as to effectively be 1 solid rod.
[19:18:55] <jmkasunich> thats what the indicator is for
[19:21:20] <Skullworks_PGAB> I got a set og gage pins and gage blocks from work - they were going to toss them because the cost to get them re-certified (as per ISO9002) cost as much as getting a new set.
[19:21:40] <chr0n1c> hey Unit41, do you have any of your music online?
[19:22:05] <jmkasunich> cool, I can actually test stuff to 58"
[19:22:24] <Unit41> yes but its in a remote section of the internet non accessable to commonfolk
[19:22:25] <jmkasunich> I had a 12", 6", and two 3" rods already
[19:22:39] <chr0n1c> oh...
[19:22:52] <Unit41> I have some tracker stuff and some alien guitar recordings
[19:23:08] <Unit41> does your dcc work ?
[19:23:10] <chr0n1c> lol, i love aliens playing guitar
[19:23:23] <chr0n1c> i tihink dcc works i never used it
[19:23:27] <alex_joni> Unit41: make it available online :P
[19:23:28] <chr0n1c> not on this pc
[19:23:33] <NightHawk_Eng> Bye guys!!! see you tomorrow!!!
[19:23:34] <chr0n1c> unit41
[19:23:39] <Unit41> i'll rapidshare it
[19:23:41] <chr0n1c> http://soundclick.com
[19:24:07] <chr0n1c> see ya NightHawk_Eng
[19:25:08] <Skullworks_PGAB> My pluto_ hit the local Post Office about 6am, too late to get on the couriers route :(
[19:25:33] <chr0n1c> Skullworks_PGAB, tell em you wanna come pick it up!
[19:25:50] <Skullworks_PGAB> they've gone home
[19:25:56] <chr0n1c> doh!
[19:26:05] <Skullworks_PGAB> they lock up at 12 noon local here
[19:26:14] <Skullworks_PGAB> on SAT
[19:26:26] <chr0n1c> i think they close at noon here also on sat
[19:26:31] <Unit41> http://rapidshare.com/files/32233122/workinit-racemusic.ogg.html
[19:27:13] <Skullworks_PGAB> I'm thinking of making a breakout board for the pluto
[19:27:21] <chr0n1c> oh unit41: http://ohiopctech.com/rdbragg <- my boss' band, he does real shows every weekend.
[19:27:36] <SWPadnos> it's probably not much harder to just make a new pluto with screw terminals ...
[19:28:09] <Skullworks_PGAB> I was thinking that too
[19:28:42] <chr0n1c> wow, what kind of effects are on the guitar?
[19:28:54] <Skullworks_PGAB> but I'm not good at fine SMT work.
[19:29:09] <chr0n1c> it sounds like osmething i would come up with in reason...
[19:29:12] <chr0n1c> something*
[19:29:52] <Unit41> I made it with audacity
[19:30:01] <Skullworks_PGAB> Could even go crazy and make a dual unit...
[19:30:03] <chr0n1c> ahh vst's?
[19:30:14] <Unit41> auto wah with reversal
[19:30:23] <Unit41> normalised and noised
[19:30:44] <chr0n1c> put a drum beat behind it and you got a song!
[19:30:51] <Unit41> its for my video game
[19:31:08] <chr0n1c> oh... interesting.. you writing one?
[19:31:23] <Unit41> me and a few
[19:31:59] <chr0n1c> for a while people were telling me everything i made sounded like it came froma video game soundtrack (when i was using fruityloops a lot)
[19:32:10] <jmkasunich> hmm... 1/2x1/2x1/8 aluminum angle is only $8.91 for an 8' piece from mcmaster....
[19:32:11] <chr0n1c> when i switched to reason, the comments got better
[19:32:18] <Unit41> lol
[19:32:21] <jmkasunich> I bet the shipping for 8' is gonna be a bit more than that
[19:32:34] <chr0n1c> about 9 bux
[19:32:41] <Skullworks_PGAB> * Skullworks_PGAB quotes "Serenity" - Sure would be nice to have some grenades...
[19:33:20] <Skullworks_PGAB> JMK - shipping will cost more...
[19:33:38] <chr0n1c> best to order two pcs
[19:33:58] <chr0n1c> that way the shipping isn't more than your parts
[19:34:10] <Skullworks_PGAB> might be better to check your local metal supplier - they can deliver by truck full lengths.
[19:34:27] <SWPadnos> 8 feet - go to Home Depot
[19:34:36] <SWPadnos> it'll be more expensive, but no shipping/delivery charge
[19:34:40] <chr0n1c> i mean tell me.. that you couldn't find another use for some extra alum. angle...
[19:35:05] <Skullworks_PGAB> Home depot stuff may not be straight anymore...
[19:35:30] <chr0n1c> lowes only carries 1/8
[19:35:33] <Unit41> http://rapidshare.com/files/32234703/workinit.ogg.html
[19:35:35] <chr0n1c> i wanted 1/4
[19:35:38] <Unit41> thats the origional
[19:35:49] <Unit41> and its months old
[19:35:59] <Unit41> like 8
[19:36:00] <jmkasunich> SWPadnos: good point, they might have that size
[19:36:13] <jmkasunich> probably only in 3 or 4 ft lengths, but thats really all I need anyway
[19:36:15] <SWPadnos> conveniently cut into 2 foot lengths ;)
[19:36:48] <chr0n1c> Unit41, they sound a lot different!
[19:37:06] <jmkasunich> what would really be nice is say 3/4 x 3/4 square bar with a groove down the length
[19:37:10] <jmkasunich> like a really long V-block
[19:37:27] <chr0n1c> what about 80/20
[19:37:39] <chr0n1c> they have some 3/4" or 1" i think
[19:37:38] <jmkasunich> that stuff is silly expensive
[19:38:19] <SWPadnos> if you'd like some 1" square 80/20, I can bring it to Fest
[19:38:35] <SWPadnos> I've got a bunch of 30-42" lengths, plus various connecting plates
[19:38:42] <jmkasunich> what kind of profile is it?
[19:38:51] <SWPadnos> their model 1010
[19:38:56] <jmkasunich> I'm looking for something with a groove that I can set 5/8" rods in
[19:39:11] <SWPadnos> hmmm - with a 1/4-20 screw in the end?
[19:39:15] <jmkasunich> * jmkasunich checks the web
[19:39:17] <Skullworks_PGAB> but there is a surplus outlet for selling rems/dropings from the leftovers of when people order exact cut sizes.
[19:39:20] <chr0n1c> we used to cut it to length.. then drill, tap and cbore it together with 1/4-20's.. skipped the whole connecting plate
[19:40:41] <SWPadnos> it's this stuff, but not that lengthhttp://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=330115157256
[19:40:48] <SWPadnos> it's this stuff, but not that length: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=330115157256
[19:40:56] <SWPadnos> there are links to the profile
[19:41:38] <chr0n1c> the center hole is ready to runa 1/4-20 tap into it
[19:41:44] <chr0n1c> at least on the 2" stuff
[19:41:47] <SWPadnos> these are already tapped
[19:42:02] <SWPadnos> some have 45 degree cuts - we used them as frames for a trade show display many years ago
[19:42:30] <chr0n1c> it works aweome for machine enclosures.. with lexan in the channel inside the box
[19:42:37] <SWPadnos> yep
[19:42:50] <jmkasunich> SWPadnos: I might take you up on that...
[19:42:55] <SWPadnos> I thikn I may even have some of the hinges, so I could make a nice door
[19:42:59] <jmkasunich> gotta figure out how wide the slot is tho
[19:43:12] <SWPadnos> lemme check
[19:43:22] <chr0n1c> 80/20 should have dims on the website
[19:43:25] <jmkasunich> 0.255
[19:43:37] <SWPadnos> yep
[19:43:48] <SWPadnos> 0.256 with my chinese calipers ;)
[19:44:09] <chr0n1c> caripers?
[19:44:17] <SWPadnos> caripels
[19:44:56] <chr0n1c> * chr0n1c hides in the corner
[19:45:09] <SWPadnos> * SWPadnos hides in the colnel
[19:45:42] <Skullworks_PGAB> * Skullworks_PGAB builds a fort from stacked up 286/386 PC's
[19:45:53] <SWPadnos> * SWPadnos has a fort from old AOL CDs
[19:46:12] <chr0n1c> hey i made a cd tower lamp from old aol cd's
[19:46:34] <chr0n1c> and some old coaster cdrs that never made it.
[19:47:39] <Skullworks_PGAB> my mom (70 yrs old...) climbs up in the fruit trees and hangs AOL cd's - the wind moves them and the reflections scare off the birds...
[19:47:42] <jmkasunich> for my purposes, the slot would be better if it was something like 0.44" wide
[19:47:58] <chr0n1c> jmkasunich, you can mill it
[19:48:17] <SWPadnos> it's anodized, but you should be able to mill it wider
[19:48:22] <chr0n1c> run a 5/8 ballnose through the slot
[19:48:24] <jmkasunich> it would be a pain in the butt, because I want a piece that is twice as long as the travel on my mill
[19:49:01] <SWPadnos> make a set of guide pins, and feed it through the horizontal mill
[19:49:02] <chr0n1c> i've milled some crazy crazy stuff with it
[19:49:06] <JymmmEMC> ds2: Ok, I'm planning on going tomorrow, but I have to go straight to work afterwards.
[19:49:12] <SWPadnos> it has tracks on all four sides, so a guide is pretty easy
[19:49:13] <chr0n1c> once i did the nested bubes in a pc. of 1" sq
[19:49:20] <chr0n1c> nested cubes*
[19:49:29] <SWPadnos> I prefer nesting in boobs
[19:49:40] <JymmmEMC> I perfer boobs
[19:49:57] <chr0n1c> yeah.. um... the cnc's don't have boobs tho
[19:49:58] <JymmmEMC> perky ones!
[19:50:17] <JymmmEMC> chr0n1c: abd how do you think they designed the inserts, huh?
[19:50:19] <SWPadnos> damn - no boobs
[19:50:29] <SWPadnos> and metal ones wouldn't be all that great anyway
[19:50:36] <chr0n1c> cold i bet
[19:50:37] <JymmmEMC> SWPadnos: ask madonna
[19:50:47] <SWPadnos> hmmm. no thanks
[19:50:53] <JymmmEMC> wuss
[19:51:00] <Skullworks_PGAB> hairy pitts
[19:51:06] <Skullworks_PGAB> noooo
[19:51:17] <chr0n1c> someone machine a 3d vagina in 6061
[19:51:35] <JymmmEMC> chr0n1c: yo get the mold
[19:51:41] <chr0n1c> :| custom bored enrty points
[19:51:43] <JymmmEMC> (pun intended)
[19:51:45] <chr0n1c> entry*
[19:52:22] <JymmmEMC> ds2: http://robogames.net/rules/combat.php
[19:52:37] <Skullworks_PGAB> to make a mold we'd have to do 3D probing... no ones going to sit still for that.
[19:52:44] <jmkasunich> SWPadnos: how long did you say the pieces you have are?
[19:52:54] <chr0n1c> do it while she is sleeping
[19:53:00] <SWPadnos> I think the square-ended ones are 30 and 42 inches
[19:53:21] <SWPadnos> but I'm not positive - some of those may have 45 degree bevels at the end
[19:53:24] <SWPadnos> one sec
[19:53:53] <JymmmEMC> jmkasunich: FWIW the SMB kernel periodically says "Badness...." upon shutdown. grub is verbose nosplash vga=791
[19:54:31] <Skullworks_PGAB> SMB?
[19:54:39] <Skullworks_PGAB> or SMP?
[19:54:40] <JymmmEMC> SMP
[19:54:50] <Skullworks_PGAB> k
[19:54:59] <SWPadnos> ok - the long ones are 47" or so, the snorter ones are 29.5
[19:55:03] <SWPadnos> shorter
[19:55:16] <Skullworks_PGAB> did you get that working smoothly yet?
[19:55:28] <jmkasunich> snorter ;-)
[19:55:40] <SWPadnos> yeah -my typoing problem seems to be getting worse
[19:55:52] <JymmmEMC> snorter.... any remember the movie Heavy Metal? LOL
[19:55:59] <SWPadnos> yes
[19:58:47] <JymmmEMC> ds2: http://makerfaire.com/pub/e/86
[20:01:27] <JymmmEMC> I gotta go charge up camera and video batteries before I forgot

[20:02:33] <JymmmEMC> yep, today and tomorrow
[20:03:07] <JymmmEMC> but, the robot wars seem to be on going...

[20:48:01] <JymmmEMC> * JymmmEMC hands robin_sz a t
[20:48:21] <robin_sz> one of my guys did a weekend there just last week
[20:48:27] <robin_sz> well, 3 days
[20:48:35] <JymmmEMC> robin_sz: was he able to walk ?

[20:48:52] <JymmmEMC> lol
[20:49:07] <robin_sz> he went for the girls, not the weed
[20:49:21] <JymmmEMC> I was JSUT gonna ask that
[20:49:32] <robin_sz> 8 in 3 days apparently
[20:49:40] <chr0n1c> thanks JymmmEMC, maybe next year
[20:49:43] <JymmmEMC> courtesans  or cannabis =)
[20:50:05] <chr0n1c> i'd go for both...

[20:51:43] <robin_sz> prague is supposed to be good too
[20:51:48] <JymmmEMC> WAY TOO HIGH HUMIDITY for me to even think about Pacific Rim
[20:52:36] <chr0n1c> a friend told me to consider a paid trip to ibiza soon.. he wants to go and has some extra cash...
[20:53:15] <anonimasu> that's nice

[20:53:41] <chr0n1c> yeah i was like dude.. i hope you aren't tryin to fcuk me
[20:54:38] <chr0n1c> it would be a shame to get down there and have him be all dissapointed cuz i'm not gay or something... lol

[20:55:11] <anonimasu> now that's scary
[20:55:24] <chr0n1c> yeah.. i was assured it was not liek that though
[20:55:40] <chr0n1c> i didn't think so but i had to bring it up
[20:55:47] <JymmmEMC> If you even have to ask/think that should tell you something.
[20:56:22] <chr0n1c> i would ask anyone who offeres to pay my way to a sweet vacation resort that question... ;)
[20:56:37] <JymmmEMC> Some friends you have.

[21:00:10] <alex_joni> robin_sz: bad weather there?
[21:00:12] <robin_sz> almost as bad as NYC
[21:00:23] <robin_sz> alex_joni, nah, its just a crowded hell-hole
[21:00:38] <JymmmEMC> robin_sz: 25 pounds to drive in isn't it?
[21:00:44] <robin_sz> shrug
[21:00:51] <robin_sz> 6 I think
[21:00:58] <JymmmEMC> ah
[21:01:06] <robin_sz> nothing really
[21:01:12] <robin_sz> compared to the gas to get there
[21:01:25] <robin_sz> its 120 miles each way
[21:01:34] <robin_sz> 240 miles ... 40 to the gallon
[21:01:45] <robin_sz> 6 gallons?
[21:01:55] <robin_sz> £32 ... $64 to you
[21:02:21] <JymmmEMC> LOL, it takes me $70 a week to fill up
[21:02:39] <JymmmEMC> and your bitching abuout $64 for a day trip
[21:03:05] <chr0n1c> nyc is sooo dirty
[21:03:16] <robin_sz> nyc IS dirty ...
[21:03:16] <chr0n1c> but there is a lot of awesome graffitti
[21:04:34] <chr0n1c> * chr0n1c spent 4 days in NYC taking pics for a dayton, ohio local band when they did a show there
[21:04:40] <chr0n1c> free paid trip!
[21:04:51] <chr0n1c> (i love my camera)
[21:04:59] <chr0n1c> *it takes me lots of fun places
[21:05:45] <robin_sz> ive been twice
[21:05:49] <robin_sz> its sorta OK
[21:06:00] <robin_sz> but so dirty and so .. well, backward
[21:06:27] <chr0n1c> i found out people are actually nice there, not like they say "ny ppl are rude"
[21:06:42] <robin_sz> we spoke to very few of them to be honest
[21:07:33] <chr0n1c> http://www.kelinginc.net/KL34H280-45-8A.pdf <- considering this motor
[21:08:00] <chr0n1c> what's the conversion factor from oz-in to the actual amount of weight the motor could move?
[21:08:24] <chr0n1c> like say would that motor move the gantry on my 24"x48" table?
[21:08:27] <robin_sz> chr0n1c, multiply by either 2013
[21:08:40] <robin_sz> or alternatively, divide by 123.5
[21:08:56] <Unit41> I hate that kelinginc guy
[21:09:05] <chr0n1c> so that would be a big diff. robin_sz
[21:09:05] <Unit41> fucking makes me mad
[21:09:25] <robin_sz> chr0n1c, so, my answer was clearly silly, right?
[21:09:27] <Unit41> when I was down and low I spent my last 500 on stepper moters and a driver
[21:09:50] <Unit41> customs kept my motors and this kelinginc guy never replaced them
[21:10:06] <Unit41> he got 300 cdn of my money
[21:10:06] <robin_sz> why should he?
[21:10:11] <chr0n1c> customs is something that still baffles me
[21:10:30] <chr0n1c> i mean go through the stuff and make sure it doesn't have drugs or guns in it and send it on the way!
[21:10:31] <robin_sz> just pay the duty
[21:10:36] <Unit41> he told me after if I withdrew my negative feed back he'd replace them if I coverd the shipping cost
[21:10:49] <robin_sz> sounds VERY fair
[21:10:52] <Unit41> now its impossable for me to remove the feedback
[21:10:56] <chr0n1c> that des sound fair
[21:11:02] <Unit41> and I'll never see them
[21:11:03] <robin_sz> no, you can mutually withdraw feedback
[21:11:04] <chr0n1c> does*
[21:11:09] <Unit41> no its been too long
[21:11:13] <Unit41> 2 years now
[21:11:15] <robin_sz> oh, oh well
[21:11:26] <Skullworks_PGAB> shouldn't leave feedback until a deal is finally finished....
[21:11:35] <robin_sz> shrug
[21:11:40] <Unit41> itd been 3 months
[21:11:48] <robin_sz> I never leave feedback UNLESS the seller leaves feedback first
[21:11:55] <Unit41> nothing came and I just left it
[21:12:02] <Unit41> feedback that is
[21:12:08] <chr0n1c> feedback is just silly unless the sale was bad
[21:12:37] <robin_sz> Unit41, it is YOUR responsibility to pay the customs duty, not his
[21:12:43] <chr0n1c> i mean otherwise you are just smoochin someones pooper
[21:12:45] <Skullworks_PGAB> I've bought from John 3x - never any problems - always fast and at a good price.
[21:12:51] <Unit41> no it was not a matter of paying customs
[21:12:59] <Unit41> it never got to its destination
[21:13:12] <robin_sz> how do you know customs kept them then?
[21:13:15] <Unit41> I phoned customs and they said they would have sent them back by now
[21:13:23] <Unit41> he said nothing came
[21:13:30] <robin_sz> how do you know customs kept them then?
[21:13:45] <Unit41> cause they never came to either of us
[21:13:51] <robin_sz> err
[21:13:55] <Unit41> maybe a discruntled employee ?
[21:13:59] <robin_sz> so the carrier could have lost them?
[21:14:06] <Unit41> ya
[21:14:19] <robin_sz> so "customs kept them" was just a guess?
[21:14:22] <Unit41> its too bad they were nice motors too
[21:14:30] <Unit41> and now im blocked from his sales
[21:14:48] <robin_sz> chr0n1c, there is no answer to the question "how much will this motor move"
[21:14:59] <Skullworks_PGAB> blocked on ebay?
[21:15:02] <Unit41> ya
[21:15:02] <anonimasu> :/
[21:15:04] <robin_sz> chr0n1c, a tiny tiny clock motor can move 10,000lb
[21:15:08] <robin_sz> just slowly
[21:15:19] <JymmmEMC> Skullworks_PGAB: A seller can block bids from a buyer
[21:15:32] <anonimasu> heh
[21:15:48] <Skullworks_PGAB> true - have you tried ordering directly from his website?
[21:16:38] <robin_sz> chr0n1c, so there is no calculation for how much a motor of a certain soze can move
[21:16:38] <Skullworks_PGAB> John has really expanded his product line.
[21:17:16] <chr0n1c> ok.. i was wondering if i could estimate the total weight my gantry could be
[21:17:17] <robin_sz> chr0n1c, but, if you know the gearing and the rack/pinion or ballscrew, I can tell you how much force a certian torque will generate
[21:17:29] <robin_sz> but thats irrelevant
[21:17:33] <chr0n1c> **which is not built yet
[21:17:38] <Skullworks_PGAB> * Skullworks_PGAB is heading out to forage for food.
[21:17:44] <robin_sz> it could weigh 10,000lb and run on an air cussion
[21:18:00] <robin_sz> or weigh 100lb and run on V slides
[21:18:11] <robin_sz> friction is a different matter
[21:18:16] <Skullworks_PGAB> 10K lbs would have killer inertia...
[21:18:19] <anonimasu> yep
[21:18:29] <robin_sz> so, slow accels then
[21:18:36] <Skullworks_PGAB> and breaking
[21:18:46] <chr0n1c> yeah, i'm going to go with roller bearings for a first run i think...
[21:18:47] <robin_sz> if you know the friction and the speeds and the accels you want, it can be calculated
[21:18:58] <robin_sz> Skullworks_PGAB, s/breaking/braking/
[21:19:12] <chr0n1c> at least 4 per side
[21:19:20] <Skullworks_PGAB> * Skullworks_PGAB I knew I should have finished differential equations...
[21:19:21] <chr0n1c> i have 8 new bearings now
[21:19:44] <Skullworks_PGAB> * Skullworks_PGAB >>> off
[21:20:42] <chr0n1c> http://www.worldwidemetric.com/metcal.htm
[21:28:31] <Unit41> how fast could a person setup a threading lathe for 10'
[21:29:10] <Unit41> would I need to start with multiple rack n pinion sections then spin the first ballscrew ?
[21:29:41] <chr0n1c> they make lathes that big
[21:29:57] <Unit41> big $$ though
[21:29:59] <chr0n1c> roll it...
[21:30:14] <Unit41> roll ballscrew ?
[21:30:26] <chr0n1c> or make a single purpose threading machine for 10"
[21:30:31] <anonimasu> gah
[21:30:34] <chr0n1c> 10'
[21:30:35] <anonimasu> chr0n1c: forget it..
[21:30:40] <anonimasu> ^_^
[21:31:07] <chr0n1c> hmm
[21:31:47] <Unit41> they actually sell rolled ballscrew ?
[21:31:55] <chr0n1c> yes
[21:32:01] <Unit41> must be cheap then
[21:32:07] <chr0n1c> cheaper*
[21:32:11] <chr0n1c> than*
[21:32:11] <anonimasu> cheap/shitty
[21:32:23] <chr0n1c> still more expensive than acme
[21:32:58] <Unit41> I bought this half inch thread rod from canadian tire thats about 10'
[21:33:01] <chr0n1c> acme is cheap and you can get it in 12'
[21:33:06] <anonimasu> errgah..
[21:33:10] <anonimasu> acme is equally shitty too
[21:33:15] <Unit41> its too fine though
[21:33:21] <Unit41> the stuff I got
[21:33:28] <Unit41> takes forever to move stuff
[21:33:30] <chr0n1c> depends on what you are building
[21:33:35] <anonimasu> yeah
[21:33:49] <chr0n1c> bridgeports use like 1"-5 i think
[21:34:20] <chr0n1c> and you can get double start
[21:34:23] <anonimasu> does bridgeports do 3d contouring with acme screws?
[21:34:30] <chr0n1c> which makes it 1"-2.5
[21:34:48] <chr0n1c> um depends on how good you are with the handles...
[21:34:53] <Unit41> do you guys pick up that acme rod locally ?
[21:35:15] <chr0n1c> i had enco ship some to me in a tube
[21:35:19] <JymmmEMC> use-enco.com has cheap acme rod
[21:35:43] <Unit41> do they accept paypal ?
[21:36:16] <chr0n1c> i don't know... maybe the paypal temp debit card
[21:36:22] <chr0n1c> the virtual credit card thing
[21:39:30] <JymmmEMC> They accept money orders
[21:43:28] <jmkasunich> enco I'm sure accepts plain old credit cards, why mess with paypal?
[21:43:50] <chr0n1c> if enco doesn't have 12' http://mcmaster-carr.com does for some types
[21:44:12] <chr0n1c> he is in another country?
[21:44:40] <robin_sz> the paypal temp card is a great idea
[21:45:20] <chr0n1c> oh wait.. it's www.mcmaster.com
[21:45:33] <robin_sz> mcnuggetts?
[21:45:41] <chr0n1c> what's with me not being able to remember domain names?
[21:45:43] <jmkasunich> no, mcmaster
[21:45:47] <jmkasunich> the big yellow book
[21:46:04] <robin_sz> chr0n1c, you fried your brain on tequilla and "the worm"
[21:46:07] <chr0n1c> the king of mail order industrial components
[21:46:16] <chr0n1c> lol robin_sz
[21:46:21] <JymmmEMC> what size length acme?
[21:46:34] <chr0n1c> he was looking for 10'
[21:46:39] <JymmmEMC> http://www.use-enco.com/CGI/INLMK3?PMK0NO=817103
[21:46:50] <Unit41> what kind do I want
[21:46:52] <JymmmEMC> 6' max
[21:47:03] <chr0n1c> i found some 12' at mcmaster
[21:47:10] <chr0n1c> but only certain grades/types
[21:47:22] <robin_sz> 3" dia?
[21:47:23] <jmkasunich> heh, the UPS guy's gotta love that
[21:47:35] <jmkasunich> 12 foot long package jammed in his truck
[21:47:59] <JymmmEMC> I'd suspect freight
[21:48:03] <chr0n1c> my 6' tube came in perfect condition, i was surprised hey didn't bend it or something
[21:48:41] <JymmmEMC> MSC only has 6' too
[21:48:46] <Unit41> so how hard would it be to spin yer own thread rod ? I allready have 10' of fine 1/2 inch fine rod
[21:48:52] <jmkasunich> mcmaster has lots of 12' ones
[21:48:59] <Unit41> and an old washing machine motor
[21:49:02] <anonimasu> Unit41: very hard.
[21:49:14] <chr0n1c> Unit41, i'd jsut buy it unless you are building a plant
[21:49:14] <Unit41> I have a shop too
[21:49:25] <Unit41> live on a farm
[21:49:33] <jmkasunich> Unit41: are you going to use the rod as a leadscrew?
[21:49:49] <JymmmEMC> wait.... 12ft of 1/2" that sounds a lil too small
[21:49:58] <anonimasu> yeah
[21:50:11] <jmkasunich> unless you are using it in tension only, and very slow speeds
[21:50:34] <chr0n1c> if you did tension it 1/2" would be interesting to try on a 6' span
[21:50:42] <JymmmEMC> deflection calculator http://www.aps.anl.gov/asd/me/Calculators/ElasticBeam2.html
[21:50:59] <anonimasu> if it's worth doing it's worth doing it right
[21:51:19] <Unit41> so what do the encoder setups look like for emc ?
[21:51:31] <jmkasunich> what do you mean?
[21:51:35] <jmkasunich> they look like encoders
[21:51:38] <Unit41> I have a bunch I robbed from printers
[21:51:54] <JymmmEMC> http://www.engineersedge.com/beam_defl_even.htm
[21:51:58] <jmkasunich> what are you building?
[21:52:05] <Unit41> a rod threader
[21:52:09] <robin_sz> JymmmEMC, just download beamboy
[21:52:22] <robin_sz> Unit41, why?
[21:52:30] <jmkasunich> what kind of rods are you trying to thread?
[21:52:30] <JymmmEMC> robin_sz: tell Unit41 =)
[21:52:59] <Unit41> what
[21:53:13] <robin_sz> download beamboy ...
[21:53:16] <Unit41> ok
[21:53:20] <jmkasunich> forget beamboy
[21:53:23] <robin_sz> the universal beam deflection tool
[21:53:24] <chr0n1c> stationary tool.... a rod spinning and being fed through the tool, multiple passes and a second operation finish tool post kind of setup on another machine
[21:53:48] <jmkasunich> Unit41: what kind of rods are you planning to thread, and why?
[21:54:02] <robin_sz> jmkasunich, too tight to buy acme rod
[21:54:05] <Unit41> I just want my own threading lathe for anything
[21:54:12] <chr0n1c> tool post grinder kind of setup*
[21:54:12] <Unit41> looks fn handy
[21:54:15] <jmkasunich> is the 12' leadscrew for building a rod-threader that will be used to thread other rods?
[21:54:35] <robin_sz> just buy a lathe with threading?
[21:54:45] <anonimasu> heh, I guess you should buy the best screws you can buy.. if you want to make screws for other machines..
[21:54:53] <jmkasunich> or do you ultimately want to build a lathe, and you are talking about building a rod threader to make the threaded rod for the lathe leadscrew?
[21:55:04] <JymmmEMC> anonimasu: get screwed! =)
[21:55:28] <anonimasu> JymmmEMC: obviously making precision screws on your own is not all that easy..
[21:55:33] <robin_sz> * robin_sz wonders if he wil lbe buying the steel or making it himself
[21:55:36] <chr0n1c> i would rather just use the magic machine wand and poof some 10' ballscrews into my garage in alike 3 seconds
[21:55:51] <jmkasunich> chr0n1c: there is such a magic wand
[21:55:55] <anonimasu> chr0n1c: what kind of precision do you want?
[21:56:00] <jmkasunich> its called piles of money
[21:56:02] <anonimasu> 0.1mm?
[21:56:09] <robin_sz> its green and has pictures of dead presidents on it
[21:56:11] <chr0n1c> everyone: they are magic so they would be perfect
[21:56:35] <chr0n1c> dead-nuts magic poof ballscrews
[21:56:41] <chr0n1c> with my wand*
[21:56:55] <anonimasu> 0.00393"
[21:57:03] <anonimasu> chr0n1c: seriously.
[21:57:09] <anonimasu> what kind of precision do you want/expect?
[21:57:13] <JymmmEMC> for every three digits to the right of the decimal point, and commas to the price.
[21:57:25] <jmkasunich> anonimasu: I don't think chr0n1c is the one who is looking for really long screws
[21:57:39] <JymmmEMC> Unit41 is/was
[21:57:39] <anonimasu> ah Unit41.. that was perhaps..
[21:57:40] <anonimasu> :D
[21:57:40] <chr0n1c> Unit41 was looking
[21:57:53] <anonimasu> Unit41: what kind of precision do you want?
[21:58:02] <robin_sz> thers a good reason why they are hard to find in long lenghts
[21:58:02] <Unit41> plasma percision
[21:58:11] <jmkasunich> Unit41 has yet to coherently tell us what he is trying to do
[21:58:15] <anonimasu> Unit41: there's no such thing..
[21:58:15] <robin_sz> screws? on plasma?
[21:58:23] <robin_sz> * robin_sz shudders
[21:58:23] <chr0n1c> +/- .062
[21:58:29] <anonimasu> ugh
[21:58:36] <JymmmEMC> Unit41: Do you want to make 4-40 threads?
[21:58:42] <robin_sz> Unit41, one suggestion
[21:58:48] <robin_sz> either rack and pinion
[21:58:49] <robin_sz> OR
[21:58:55] <robin_sz> toothed linear belt
[21:58:55] <Unit41> chain
[21:59:12] <anonimasu> that'll clog up nicely too
[21:59:12] <robin_sz> I built my plasma with toothed linear belt
[21:59:15] <chr0n1c> bike chain is cheap
[21:59:22] <JymmmEMC> Unit41: Do you want to make 4-40 threads or smaller?
[21:59:27] <robin_sz> I built and sold about a dozen of them
[21:59:50] <Unit41> jymmm im not sure with all this technical numbers
[22:00:06] <JymmmEMC> Unit41: Do you know what a 1/4-20 bolt looks like?
[22:00:44] <Unit41> is that the standard ole homehardware 1/4 inch fine ?
[22:01:05] <Unit41> there are only 2 kinds I found
[22:01:09] <Unit41> fina and coarse
[22:01:12] <robin_sz> there is a damn good reason they dont sell 10' acme rod
[22:01:18] <robin_sz> bvecause it WOnT WORK
[22:01:29] <JymmmEMC> 1/4" diameter, 20 threads per inch. One of the most common bolts around SAE wise
[22:01:39] <robin_sz> WONT WORK
[22:02:07] <JymmmEMC> Unit41: Do you know the smallest size you want to create?
[22:02:27] <jmkasunich> Unit41: I don't want to hurt your feelings, but if you don't know what 4-40 or 1/4-20 threads are, you are in WAY over your head trying to build a 10 foot lathe
[22:02:27] <JymmmEMC> Unit41: or the largest size thread you want to create?
[22:02:31] <Unit41> just coarse
[22:02:38] <Unit41> I dont need fine threads
[22:02:45] <robin_sz> a plasma needs to do high speeds, you WILL NOT get it to high speeds on a 10' length of fine pitch rod
[22:02:46] <Unit41> maybe the handle of a broom or something
[22:02:59] <JymmmEMC> Unit41: Ok, gice us the diameter smallest and largest you want to create
[22:03:02] <JymmmEMC> give
[22:03:06] <jmkasunich> robin_sz: wtf does plasma have to do with anything?
[22:03:07] <anonimasu> Unit41: I dont usually say this but, you need to read some books.
[22:03:13] <jmkasunich> I thought he wanted to make a lathe
[22:03:14] <JymmmEMC> Unit41: ok broom handle is about 1"
[22:03:19] <robin_sz> jmkasunich, thats what hes tryingto build
[22:03:33] <jmkasunich> hes gonna thread things with a plasma?
[22:03:40] <robin_sz> <anonimasu> Unit41: what kind of precision do you want?
[22:03:40] <JymmmEMC> Unit41: how small? pencil size?
[22:03:45] <Unit41> ya
[22:03:48] <robin_sz> Unit41> plasma percision
[22:03:57] <JymmmEMC> pencil size is about 1/4" diameter
[22:04:13] <JymmmEMC> Unit41: I would HIGHLY suggest that you look at a bolt chart
[22:04:19] <robin_sz> jmkasunich, no hes trying to build a plamsa tabkle I think, but wants to make the acme screws rather than buy them
[22:04:37] <jmkasunich> oh
[22:04:48] <jmkasunich> well why the fsck didn't he say that in english
[22:04:58] <jmkasunich> I asked exactly that question, twice!
[22:05:02] <JymmmEMC> Wouldn't it be better to just use belts on a plasma table?
[22:05:12] <anonimasu> JymmmEMC: Yes
[22:05:22] <robin_sz> yes
[22:05:27] <robin_sz> or rack and pinion
[22:05:42] <Unit41> what kinda belt ?
[22:05:53] <chr0n1c> i'd go rack n pinion
[22:05:57] <JymmmEMC> robin_sz: He doens't know threads, I doubt R&P is gonna come into play on this.
[22:06:07] <chr0n1c> no belts to break that way*
[22:06:21] <robin_sz> belts are easier to align :)
[22:06:39] <Unit41> just use a belt off a hey bailer ?
[22:06:44] <anonimasu> * anonimasu goes away
[22:06:48] <anonimasu> this scares me
[22:06:53] <jmkasunich> Unit41: toothbelts
[22:06:55] <chr0n1c> * chr0n1c wonders how they will cut the hay
[22:07:16] <jmkasunich> Unit41: you really do need to read some books, or websites, or both
[22:07:45] <JymmmEMC> http://www.mcmaster.com/param/asp/PSearch2.asp?reqTyp=parametric&act=psearch&FAM=belts&FT_158=33429&desc=Synchronous+Belts&dscIDs=36264&sesnextrep=846965473497941&ScreenWidth=1600&McMMainWidth=872
[22:10:13] <Unit41> you guys will laugh at my mill but I'll go snapa few shots
[22:11:58] <JymmmEMC> LOL, I love it!!! (if you remember the board game) http://makerfaire.com/pub/e/216
[22:23:21] <Unit41> no pictures
[22:23:28] <Unit41> cant find my other rechargable
[22:23:44] <Unit41> found it
[22:25:33] <Unit41> in the mein time I'll just eat some mushrooms
[22:28:13] <Unit41> I bought em over a month ago but I know forsure there still good
[22:28:13] <Unit41> still taste ok
[22:28:39] <Unit41> whats thebest way to fasten that belt together ?
[22:29:01] <Unit41> or just lay it down in a strip and put ta gear on the stepper
[22:30:24] <robin_sz> umm
[22:30:33] <robin_sz> the belt goes on a rail
[22:30:37] <robin_sz> FACE DOWN
[22:31:00] <robin_sz> you have pulley, gear, pulley ..
[22:31:02] <robin_sz> like err
[22:31:07] <robin_sz> o O o
[22:31:28] <robin_sz> it goes under the first pulley, up over the gear, back down under the second pulley
[22:31:49] <robin_sz> do that on each side
[22:31:52] <robin_sz> connect to
[22:32:00] <robin_sz> the two gears on each side with a shaft
[22:32:21] <Unit41> neat idea
[22:32:39] <robin_sz> wanan see a picture or two?
[22:32:55] <Unit41> not unless you allready have them ready to see

[22:34:12] <robin_sz> white belts
[22:34:30] <robin_sz> see the connecting shaft going across underneath?
[22:35:15] <alex_joni> http://www.redpoint.org.uk/photos/machine2/DCP_1201.JPG <- you can see the belt better here
[22:36:26] <alex_joni> anyways. off to beuty sleep for me
[22:36:28] <alex_joni> night all
[22:36:34] <robin_sz> night
[22:36:57] <jmkasunich> goodnight
[22:37:00] <Unit41> its just sitting on it
[22:37:12] <Unit41> not all bunged in the cogs
[22:37:12] <robin_sz> no
[22:37:29] <robin_sz> the belt is teeth down
[22:37:32] <robin_sz> http://www.redpoint.org.uk/photos/upload/P1000840.jpg
[22:37:38] <robin_sz> thats whats inside basically
[22:37:56] <robin_sz> it goes like a letter omega
[22:38:22] <robin_sz> oOo under, over, under
[22:38:51] <robin_sz> the belt stays still, the carriage moves
[23:06:54] <Ziegler> anyone know what the latency of the hobbycnc board is?
[23:07:07] <SWPadnos> 20 ns?
[23:07:50] <Ziegler> you know where that value is listed?
[23:07:57] <Ziegler> seems reasonable
[23:08:04] <SWPadnos> no, but are you talking about a parport breakout board?
[23:08:58] <Ziegler> HobbyCNC.com
[23:09:54] <SWPadnos> uh - I'm not sure latency is a valid measurement for those driver boards
[23:10:25] <Ziegler> huh?
[23:10:36] <SWPadnos> I guess I'm not sure what you're asking :)
[23:10:57] <Ziegler> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?TweakingSoftwareStepGeneration
[23:11:04] <Ziegler> I have the latency of my comptuer
[23:11:19] <Ziegler> I am looking for the latency of my driver now so that I can combine the two
[23:11:42] <SWPadnos> ah - not latency, minimum step pulse / space durations
[23:11:57] <Ziegler> oh ok
[23:13:35] <SWPadnos> dunno. I'm not sure which driver chip they use, but that would be the place to look - get the datasheet from the manufacturer of the chip
