[00:22:45] <eric_unterhausen> I ordered something from Misumi, they tried to fax something to me
[00:22:49] <eric_unterhausen> who does that anymore?
[00:23:43] <Chemeleon> its getting rare, but hasnt completely died out yet for some reason
[00:23:49] <eric_unterhausen> I figured lying to them about my fax number wouldn't be a big deal
[00:23:57] <eric_unterhausen> they tried to fax me 5 times

[00:33:22] <nspiel> what is the correct way to make the headers that go on the mesa boards? I have the headers with wires in them but i want to take the wires out and put new ones in
[00:35:28] <cradek> be careful to not pull the pins out or break any plastic tabs when you remove the old wire. there is a special tool for crimping it, but a bench vise or a machine vise both will work fine.
[00:35:45] <cradek> I bet they're really not meant to be reused, but we've all done it anyway.
[00:37:57] <eric_unterhausen> there would have to be a really good reason for me to take the wires out of a 50 pin ribbon cable
[00:39:23] <Jymmm> Most ppl just roll the connector into the cable to shove it thru a 1/2" or so hole

[00:43:29] <nspiel> problem is I dont have a bench vice haha
[00:48:24] <nspiel> can u crimp them with pliers or something like that
[00:48:35] <Jymmm> Not reliably
[00:49:47] <Tom_itx> in a pinch i've slammed a drawer shut on em
[00:49:52] <nspiel> is the tool called a wire crimping tool or something else
[00:49:52] <nspiel> lol
[00:49:54] <nspiel> tom
[00:49:58] <Tom_itx> it works
[00:52:38] <Jymmm> IDC Crimper iirc
[00:53:46] <Jymmm> yep, that's it

[01:51:51] <pcw_home> nspiel: I did a detailed list of how to connect the two 7I25s to one 7I43 connector, it should be findable in the IRC logs
[01:53:46] <nspiel> sorry to be a noob but what are the IRC logs?
[01:53:54] <Tom_itx> logger[mah]_
[01:53:54] <logger[mah]_> Tom_itx: Log stored at
http://linuxcnc.mah.priv.at/irc/%23linuxcnc/2013-08-20.html
[01:53:56] <Tom_itx> that
[02:03:27] <nspiel> but wasnt it just detailing connecting the 7i43 via the split 50 wire connector? I already did that.I am now working on wiring that setup to my robot arm
[02:05:09] <pcw_home> OK, so this is just wiring the7I25 encoder and motor connectors?
[02:05:21] <nspiel> yep
[02:05:32] <nspiel> but im making the female headers to connect to the robot
[02:07:05] <nspiel> it basically has a giant parallel output port on the back breaking out to a connector with a big ribbon cord that i have to pull all the encoder power and signals from then wire that to the 7i25s

[15:22:08] <archivist> hmm I want to gear axes together, this gearing completely unrelated to spindle and I do not want to restart ie not in hal but in gcode, hence can then be a gear measuring machine
[15:23:20] <cradek> you want to move a couple axes proportionally? can't you just do that with coordinated motion?
[15:23:36] <archivist> eg jog xyz to get the dial indicator onto a tooth, jog B and A rotates in gear so that the dti measures error or lack of it
[15:25:21] -!- tchaddad has quit [Remote host closed the connection]
[15:25:35] <cradek> earlier you said gcode - but you mean some kind of manual jogging?
[15:25:46] <cradek> not quite seeing what you want yet
[15:26:52] <archivist> if I manually jog B I want A to move also, if measuring a bevel then xy relate as well
[15:27:24] <archivist> it could make some part programming easier too
[15:30:02] <archivist> to be able to do the cone roll from
http://www.collection.archivist.info/archive/DJC/BK/BK2918/page_0087t.jpg or similar

[15:35:15] <archivist> I am at the stage of thinking I am getting the involute right on the bevels, they mesh ok, but there is an angle error I need to diagnose
[15:35:42] <archivist> skunkworks__, nah straight bevels is all I have to do
[15:35:49] <skunkworks__> ah
[15:36:00] <skunkworks__> Saw the pictures - very nett
[15:36:01] <skunkworks__> neat
[15:36:28] <archivist> not neat enough to extract payment for them though :(
[15:36:58] <skunkworks__> how many do they need?
[15:37:13] <archivist> only one pair
[15:38:51] <archivist> when making clock gears we would approximate stuff to get "near enough", not sure on bevels where the approximations are and where I have to get it right

[16:58:52] <IchGuckLive> hi all B)
[16:59:07] <JT-Shop> last mystery solved for the PLC so it off to lunch
[16:59:44] <IchGuckLive> lunch is better to lanch O.O
[17:00:03] <Chemeleon> any of ya'll know of any popular blog type sites for cnc routers?
[17:01:14] <IchGuckLive> here ?
[17:01:29] <IchGuckLive> its live so what is wrong with that
[17:01:53] <Chemeleon> I'm trying to figure out if theres anywhere else I should send announcements about the cam software I'm releasing :)
[17:02:20] <Chemeleon> cnczone, mycncuk, and reddit so far, reddit by far has driven the most site traffic
[17:02:54] <IchGuckLive> cam is good is it open
[17:03:12] <Chemeleon> not open source, and windows only, but significantly cheaper than what everyone else sells
[17:03:23] <Chemeleon> www.diy-cam.com first program is a heightmap generator for 3d carving
[17:03:40] <Chemeleon> right now, working on support to convert the alpha map of an image to a profile cut path, so you can have it cut out carvings rather than just leave them square
[17:06:49] <MattyMatt> I'll sell you a blender script cheaper >:)
[17:07:10] <cradek> Chemeleon: my gentle advice is to be careful; free software advocates can be quick to call your announcements spamming. be sure you know your audience.
[17:07:40] <Chemeleon> cradek, yea, thats one of my main hesitations (and only linked it this time here because IchGuckLive was asking about it)

[17:10:50] <Chemeleon> from what I've been able to find for similar programs on windows, they're all either less capable, cost significantly more, or both
[17:11:07] <Chemeleon> and this one is mostly just kinda a warmup, planning several further projects
[17:11:25] <Chemeleon> but need it to sell well enough I can focus on them, rather than have to make them side projects while doing something else to earn a living :)
[17:11:26] <MattyMatt> what ties it to windows?
[17:11:46] <IchGuckLive> Chemeleon: on linuxcnc all is free
[17:11:50] <Chemeleon> currently, its .net and dx for the preview, I could port it to c++/opengl if I had to
[17:12:04] <Chemeleon> but my main reason for windows only, is I'm not comfortable selling on a platform I'm confident I can provide support for
[17:12:20] <cradek> perhaps you should try selling to mach users
[17:12:20] <Chemeleon> I've used linux and macs in the past, but if someone ran into a weird bug, it might stump me
[17:12:23] <jthornton> you might attract Mack users they like to pay and love windoze
[17:12:30] <Chemeleon> heh, yea :)
[17:13:16] <Chemeleon> most of my work in the past has been video game development, nearly every way you release there, you've got instant eyes on things due to new release lists, etc
[17:13:22] <IchGuckLive> i got no winddoof as far as 2008
[17:13:27] <Chemeleon> I miss that ease of getting peoples attention :)
[17:13:27] <IchGuckLive> since
[17:13:48] <IchGuckLive> there are alot of free stuff that make this height maps

[17:15:17] <MattyMatt> g1 z-1000
[17:15:26] <MattyMatt> easy :)
[17:15:44] <Chemeleon> yea - even if it wasnt my fault, just far too many ways to accidentally destroy things with controller software
[17:15:51] <Chemeleon> at least with gcode, I'm somewhat insulated from that
[17:16:09] <IchGuckLive> MattyMatt: haas wiss do this as you forgot the DOT
[17:16:16] <MattyMatt> a preview in the controller will show up any insane cam moves
[17:16:37] <jdh> axis doesn't really do a great job of preview for some things.
[17:16:49] <Chemeleon> yea, theres several times you can catch a gcode issue and its also a lot easiaer to notice if a bug causes one
[17:16:52] <jdh> it would be nice to be able to step through code
[17:17:16] <Chemeleon> bug in the controller could result in unexpected movement though
[17:17:22] <Chemeleon> liked the idea of my own, didnt like the scariness of it :)
[17:17:42] <MattyMatt> bug in controller wouldn't be your problem
[17:17:55] <IchGuckLive> im using now kinuxcnc since 2008 and never got a failue of the interpreter
[17:18:03] <jdh> I have
[17:18:10] <jdh> <- interpreter
[17:18:26] <Chemeleon> I've got an accurate previewer in this one, but I've had a couple friends request a more complex viewer only app - things like loading multiple gcode files with ability to move/rotate/scale, etc
[17:18:31] <jdh> all my problems have been my MDI typing
[17:18:35] <MattyMatt> only fail I have is infinite loops hard crash machine
[17:18:36] <Chemeleon> so thats probably going to be my next project before the big vector/vcarve one
[17:19:41] <Chemeleon> not sure theres really much market for it, but it should be a fairly quick project, and parts of it I'll need for other things anyway

[17:22:21] <MattyMatt> aewallin was doing a neat voxel preview, so you could see the result as well as the tooolpaths
[17:24:10] <Chemeleon> I experimented briefly with a very basic voxel setup initially, but decided for heightmaps just a normal mesh was simpler
[17:24:28] <Chemeleon> going to need something more complex for the vector app though since you can seperate pieces, etc
[17:24:34] <IchGuckLive> anderswallin is way ahad of you
[17:24:46] <Chemeleon> not sure yet if I'm just going to improve my mesh algorithm, or try voxels again for it
[17:25:01] <IchGuckLive> and his TTT is the burner itself
[17:25:18] <Chemeleon> voxels definitely have some benefits, but given the detail levels involved, not sure they're real practical

[17:41:33] <IchGuckLive> NP
[17:41:56] <Chemeleon> any idea how well that voxel preview does when you get into smaller scale stuff like a 1/16" bit?
[17:43:43] <MattyMatt> voxels can go to any resolution. it'll just get slower and memhungrier
[17:44:12] <Chemeleon> true
[17:44:25] <MattyMatt> rammier
[17:44:36] <Chemeleon> guess the better question is can it do high detail without completely killing view performance
[17:44:44] <Chemeleon> though even then, you can go adapter to lower detail when moving
[17:45:21] <Chemeleon> go adapter? not really sure what I was typing there :)

[17:46:17] -!- c60 [c60!~nils@50.93.63.136] has joined #linuxcnc
[17:46:51] <MattyMatt> voxels aren't worse than the million gl_Line()s in the toolpaths
[17:47:32] <MattyMatt> they probably are when drawn in GL tho
[17:47:59] <MattyMatt> you can't use the software rendering tricks like raycasting games
[17:49:05] <Chemeleon> I'll probably play around with voxels sometime in the next couple weeks
[17:49:12] <Chemeleon> even if I decide to stick with mesh, its fun code to write :)
[17:50:26] <MattyMatt> I had an idea for a hybrid system, simple meshes at the deepest level of voxels, so when your cutter make a million tiny polys in a tiny space, they are easy to simplify
[17:50:45] <Chemeleon> sort of like caching the voxels to mesh?
[17:51:35] <MattyMatt> yeah, and no poly extends beyond the voxel, so worst case is "panic and clear voxel"
[17:51:55] <Chemeleon> makes sense, especially if you can detect areas the bit will no longer modify
[17:52:04] <Chemeleon> I also want to setup some more realistic shaders when I work on the viewer app, so you can do things like preview how light would bleed through a lithopane
[17:52:33] <Chemeleon> most of my work on games was in art and graphic rendering, so that stuff is fun
[17:52:34] <MattyMatt> blender is good at that sort of thing, once you have a mesh
[17:52:37] <Chemeleon> and makes for cool screenshots :)
[17:53:06] <Chemeleon> sure, but last I checked, blender wont do an accurate simulation of a gcode file obeying bit geometry first :)
[17:53:13] -!- tmcw has quit [Remote host closed the connection]
[17:53:49] <MattyMatt> true that. voxels objects in blender would help
[17:54:40] <Chemeleon> the other "big" thing I want of the viewer, is the ability to rearrange the post-simulation parts, so you can do a final assembly of the work to show clients, with proper materials, etc
[17:54:48] <MattyMatt> I have more important hacks to blender on my todo tho. persistent parametric objects would make it a lot more like solidworks etc
[17:55:02] <Chemeleon> I've not yet come across a way to simulate and them assemble a project to see what the final result would be, ie for signs glued up of multiple pieces
[17:55:26] <Chemeleon> I can do it pre-gcode in 3dsmax of course, but then you've got a disjoint that might hide flaws
[17:57:31] <MattyMatt> trial and error seems best. getting a faithful rep of optical properties of a material would be a job in itself
[17:58:19] <MattyMatt> until perspex sellers offer 3ds material properties as a download :)
[17:59:45] <Chemeleon> yea, I figure what I'll likely do, is just cut materials like corian to various thicknesses, and adjust the shader until it visually matches what I'm holding in hand
[17:59:51] <Chemeleon> but leave values exposed so users can tweak things as wanted
[18:00:43] <MattyMatt> I just tweak blender's default shader values. it does the job for me
[18:01:20] <MattyMatt> I can tell the diff between brass and wood onscreen. that'll do me

[18:15:30] <Chemeleon> footprint would be by something like 18x28", so a touch big by desktop standards perhaps, but I have a *very* big desk, so it'll fit fine :)

[18:37:46] <Chemeleon> and the couple that dont, the central hallway zigzags, clipping off a corner
[18:38:22] <Chemeleon> I do kinda wish I could break the desk somehow, as I'd like the excuse to build one "properly" now that I know what I'm doing
[18:38:32] <Chemeleon> but the floor would give way before anything would break that desk :)
[18:38:58] <MattyMatt> crosscut saw
[18:39:06] <MattyMatt> good exercise
[18:39:08] <Chemeleon> heh
[18:39:38] <Chemeleon> the one issue, is its only desk surface, no enclosed storage
[18:39:48] <Chemeleon> that picture was the only time it was ever truly clean and neat :)
[18:40:09] <Chemeleon> just picked up a couple dressers cheap at a local auction though, so starting to use them for storage, seems like it should solve most of the issue
[18:41:18] -!- vladimirek has quit [Ping timeout: 264 seconds]
[18:41:29] <Chemeleon> had planned to build some rolling drawers to fit under the desk, but these were cheaper than material cost
[18:42:27] <MattyMatt> that's what I've done, plus a room with floor to ceiling shelves all round
[18:42:54] <Chemeleon> yea, I've got plans for a ton of built ins here eventually
[18:42:56] <MattyMatt> does your tablet have a wacom-style pen?
[18:43:05] <Chemeleon> its the usual issue with old houses, no closets
[18:43:12] <Chemeleon> yea, thats an older wacom cintiq
[18:43:17] <MattyMatt> sweet
[18:43:29] <Chemeleon> was a splurge one year when I wanted more of a tax writeoff at the end :)
[18:44:04] <Chemeleon> my intuos 6x8 was reaching the point where it was too beat up to keep using, wanted a bigger tablel anyway, and between the tax writeoff, cost of a larger intuos, etc, the premium for it wasnt *too* bad
[18:44:27] <MattyMatt> my sister needs that, she's an artist but couldn't handle the plain pad
[18:44:37] <Chemeleon> these days, I'm using a surface pro (MS's tablet)
[18:44:51] <Chemeleon> works just as well as the cintiq ever did, but Im not tied to my desktop
[18:45:01] <MattyMatt> I'm still using an aiptek :) nice big one tho, 18x12 iirc
[18:45:03] <Chemeleon> the bigger screen on the cintiq is nice, but the surface's is plenty big enough to be usefulu
[18:45:19] <Chemeleon> though lately, I seem to have lost the pen for it :\
[18:45:30] <Chemeleon> I swear, wacom pens can move themself
[18:46:14] <MattyMatt> yep I lost my first aiptek one
[18:46:22] <MattyMatt> in a one room apartment
[18:46:29] <Chemeleon> heh
[18:46:46] <Chemeleon> I've turned around, found the pen missing, only to find it 15 feet away without me having walked over there
[18:46:59] <MattyMatt> I think people pick them up, try to write with them, then throw them away
[18:47:28] <Chemeleon> and unfortunately, while the surface pro uses wacom tech, it uses their tablet line of pens, not compatible with the intuos style pens
[18:47:29] <MattyMatt> "stupid biro"
[18:47:33] <Chemeleon> heh

[18:49:33] <Chemeleon> their last desktop, burst into fire while she was playing solitair
[18:49:49] <Chemeleon> she went to get a cat scan on a shoudler injury a few weeks ago, and the machine died
[18:49:56] <Chemeleon> fixed itself the moment she left the room
[18:50:39] <Chemeleon> and I once was printing a 70ish page word doc, about halfway through she stepped near the printer, and it went from normal text to wingdings looking stuff

[19:16:55] <Jymmm> QUESTION: I have a lot of thin lightweight flat material (48"x24" or smaller) that needs to be stored flat too, but can't really "stack" it, because you know the one you want is always on the bottom. I was thinking of some sort of "sandwich" thing, then I could store that on a shelf, pull out and flip thru accordion style, and pull what I need. Any suggestions???
[19:17:27] <Chemeleon> how thin/what material?
[19:17:34] <MattyMatt> remember Athena posters?
[19:18:27] <Jymmm> 1/2" thick would be the max, 1/4" on average. Acrylic sheet, cardboard, foamboard, etc
[19:18:42] <MattyMatt> big in the 70s/80s, they had a couple of neat shop fittings for browsing, but maybe not quite 48x24
[19:18:43] <Jymmm> lightweight I guess is relative here =)

[19:19:00] <Jymmm> MattyMatt: never heard of them
[19:19:10] <MattyMatt> probably UK only
[19:19:13] <Jymmm> ah
[19:19:21] -!- CptHS has quit [Client Quit]
[19:19:39] <Jymmm> Oh and rubber/silicone sheets too
[19:19:54] <Jymmm> I guess those are kinda heavy due to their density
[19:20:15] -!- CptHS [CptHS!~LostLunch@96.25.134.150] has joined #linuxcnc
[19:20:29] <Chemeleon> if you want something fancier, whats coming to mind currently, are the poster displays stores like walmart have, might be similar to what you meant about accordian style
[19:20:44] <Chemeleon> but I would think most sheetgoods, you could just slide into a cubby on edge?
[19:20:54] <Jymmm> Chemeleon: But those are vertical is the only problem
[19:21:14] <MattyMatt> lotsa very thin shelves/drawers?
[19:21:19] <Chemeleon> oh, whoops, missed you wanted it stored flat but not stacked :)
[19:21:19] <Jymmm> Chemeleon: these ahve to store flat - horizontal
[19:21:36] <MattyMatt> athena's most famous image. PNSFW
http://ecx.images-amazon.com/images/I/617zlePqwcL._SL1000_.jpg
[19:21:41] <Chemeleon> agreed with matt - lots of shelves to store sorted by type is probably simplest
[19:21:52] <Chemeleon> if they were a bit smaller, I'd say maybe just a toolbox
[19:22:00] <Chemeleon> but getting one that'd hold 24x48" would be pricey
[19:22:03] <Jymmm> MattyMatt: Ah, I remember that poster well =)
[19:22:35] <Jymmm> Yeah, I was thinking blueprint drawers, but they are too $$$ and too deep
[19:24:07] <MattyMatt> adjustable shelves? use the 1/2" stock as the shelves :)
[19:24:23] -!- caprico has quit [Ping timeout: 250 seconds]
[19:25:41] <Jymmm> I have these now;
http://www.affordableshelving.com.au/images/wireshelf-main.jpg
[19:26:02] <Jymmm> 18" Deep x 48" Wide shelf
[19:27:54] <MattyMatt> those knock-off snap-on tool cabinets have big flat drawers, some of them
[19:28:13] <MattyMatt> and when you get bored, it's still a good tool cabinet
[19:28:30] <MattyMatt> they cost $$$ too tho :p
[19:29:51] <MattyMatt> best idea. drill 2 small holes in each sheet, then hang from ceiling by 2 threads each
[19:30:59] <MattyMatt> put a light + blowing air = art installation
[19:37:18] <Chemeleon> heh
[19:39:59] -!- syyl_ws has quit [Quit: Verlassend]
[19:41:29] <Jymmm> Eh, fuck it... I found a piece of 1/2" MDF that's 36" x 31". I'll rip it down to 36x24, cut a notch on the bottom side and just clamp it to the chrome racks as an overhang.
[19:41:57] -!- CptHS has quit [Ping timeout: 248 seconds]
[19:42:12] <Jymmm> I'll just deal with the "what I need is on the bottom of the pile" crap =)
[19:42:28] <Chemeleon> matt's mention of air might help there
[19:42:46] <Chemeleon> if you have an air compressor, and can kinda wiggle the nozzle under the edge, a could burst should help break that surface suction effect
[19:42:58] <Chemeleon> could = quick
[19:43:33] <Jymmm> Chemeleon: some stuff is too dense, but nice idea =)
[19:43:47] <Chemeleon> just means you need a bigger air compressor ;)
[19:43:58] <Chemeleon> there is very little that cant be solved by buying bigger tools :)
[19:44:56] <Jymmm> I dont have any air compressor. Just a N2 tank =)
[19:45:57] <Jymmm> But it'll do 2000 PSI =)
[19:46:10] <Chemeleon> if the sheets are all the same size in one direction, another option would be to make a box with just a series of dados on the two side walls
[19:46:20] <Chemeleon> close together, maybe 1/4" gap or so
[19:46:27] <Chemeleon> and 1/4" spacers you can sit in the middle to keep things from sagging
[19:46:45] <Chemeleon> easier and less material than building a bunch of shelves at least
[19:46:51] <Jymmm> Chemeleon: The material iself is acrylic, it'll sag from the weight/heat
[19:47:00] <Chemeleon> yea, hence the spacers :)

[19:47:08] <Jymmm> Noooooooooooooooooooooooooooo
[19:47:09] <Chemeleon> sorta like stickering wood
[19:47:43] <Chemeleon> hmm, actually, slightly flawed - you'd still have to have a continous stack from the bottom
[19:47:51] <Chemeleon> so you'd have to move one from above down if you pulled one from below
[19:47:57] <Jymmm> I'll just with the stacking
[19:48:15] <Jymmm> ^deal
[19:48:57] <Jymmm> The gorilla rack (which is what I'm storing them on now) is going with the CNC Router
[19:49:22] <Jymmm> And it's too damn heavy for me to want to keep/replace it.
