[00:14:28] <roycroft> the little kiln i just bought will melt aluminum
[00:14:57] <roycroft> aluminum melts at 660c
[00:15:03] <roycroft> you can melt it with a propane torch

[00:40:46] <jdhNC> ctj: they are "those green plug in phoenix connector things"
[01:12:07] <r00t4rd3d> http://www.ebay.com/itm/PHOENIX-CONTACT-1792058-MVSTBR-2-5-6-ST-plug-/190560554527?pt=LH_DefaultDomain_0&hash=item2c5e4b4e1f
[01:12:14] <r00t4rd3d> in new york and cheaper then digi
[01:14:58] <jdhNC> if you just need one, I have a 6 sitting here.
[01:15:23] <r00t4rd3d> "combicon plug"
[01:15:31] <r00t4rd3d> I guess is the proper name for them
[01:16:14] <jdhNC> there are lots of names. Lots of places make them. McMaster has them
[01:31:32] <ctjctj> thank you r00t4rd3d I've got it covered now. You guys got me to the right place which is what I was asking for.
[01:32:16] <ctjctj> In the mean time I'm finding programming in g-code/o-code to be frustrating at best and dangerous to equipment at worse
[01:33:29] <ctjctj> Stupid little things like 38.5 will break contact with my touch plate but there is still spring so the g0z(up) gives me "probe fired during non-probe mdi"
[01:48:27] <cradek> maybe you need to debounce it?
[02:01:36] <ctjctj> Mechanically or electronicly?
[02:02:29] <r00t4rd3d> did you make your touch plate?
[02:03:13] <ctjctj> yep. wire to piece of pcb board. other end to ground. alligator clip to bit, other end to in.motion pin.
[02:04:25] <r00t4rd3d> there is so much i need to learn
[02:04:55] <ctjctj> Same here.
[02:04:59] <r00t4rd3d> think i am just gonna smoke crack instead
[02:06:42] <r00t4rd3d> I hate myself for liking The Big Bang Theory on TV.
[02:07:11] <jdhNC> she used to be hot and you used to want to be 'that guy'?
[02:09:06] <ctjctj> Ok. why did my feedspeed for rapids drop suddenly? Makes no sense to me...
[02:09:30] <jdhNC> did you change feed override or max speed?
[02:13:06] <ctjctj> nope.
[02:13:41] <ctjctj> Everything seemed to be working correctly. Then I did a g54 g1z0.85f2 and after that all movement was "slow"
[02:13:58] <Aero-Tec> KimK: are you around?
[02:14:08] <Aero-Tec> got up for a bit
[02:14:15] <jdhNC> G0 is slow, or just all G1?
[02:14:20] <ReadError> i gotta admit
[02:14:26] <ReadError> i been trying alot of drafting programs
[02:14:30] <Aero-Tec> will stick around awhile
[02:14:31] <ReadError> the best by FAR is solid works
[02:14:37] <ReadError> its super intuitive
[02:14:47] <Aero-Tec> I use solid works
[02:14:53] <Aero-Tec> great program
[02:14:58] <ReadError> wish they had a hobby version
[02:15:02] <Aero-Tec> not cheap
[02:15:02] <ctjctj> g0 is slow.
[02:15:05] <ReadError> 12k....
[02:15:06] <ReadError> jesus
[02:15:21] <ReadError> its like come on guys, i dont need all the motion stuff
[02:15:25] <ReadError> just gimme the modeling!
[02:15:47] <ReadError> Aero-Tec, what do you use to convert to gcode?
[02:15:49] <ReadError> thats where im at now
[02:15:52] <jdhNC> I went to a design review last week for a new machine we are having built. Their mechanical guy had done it all in SW and made it look really impressive (cylinders extending, everything moving, etc)
[02:15:54] <Aero-Tec> there are some hacked versions out there
[02:15:56] <ReadError> pycam seems to have issue
[02:16:04] <ReadError> Aero-Tec, ;)
[02:16:10] <Aero-Tec> I have bob cam for solid works
[02:16:17] <ReadError> oh? does it work nicely?
[02:16:28] <Aero-Tec> but I hand code most of my stuff
[02:16:37] <ctjctj> Problem started with a G28.1 which sets my goal. G28 Z3 which should raise the Z to abs 3in but it didn't. Just took off for the goal xyz
[02:16:48] <ctjctj> pycam is not may favorite software. :-(
[02:17:09] <ReadError> its good for some stuff
[02:17:21] <ReadError> but for instance, i have a 0.125" endmill
[02:17:29] <ReadError> and it doesnt do my 0.125 holes
[02:17:37] <ReadError> i just want it to drill down...
[02:17:57] <ctjctj> Got my code output good g-code for profiles (inside, outside, on) but then got burned out trying to draw a stupid graphic for the UI to show climbing vs. conventional cutting.
[02:18:06] <Aero-Tec> use cam for fancy 3D models, but even then I only cam the fancy curves and contours, the rest is hand coded
[02:18:13] <ReadError> i dont like how it resets everything when your restart it
[02:19:23] <Aero-Tec> yes bob cam for solid works is nice, but then again not cheap
[02:19:35] <ReadError> is there a ....version?
[02:19:45] <jdhNC> I've never used G28. Might be hazardous the way I leave things around.
[02:20:50] <Aero-Tec> I started machining for myself, but every thing I needed was so expensive that I started machining for others so I could afford the nice programs
[02:20:52] <ReadError> visualmill made a nice path
[02:21:00] <ReadError> but its payware....
[02:21:01] <ctjctj> I'm using it to move to the "tool touch plate" Seemed like the "right" way to do it. Looks like I should just use a couple of g53 g0 lines. Less fancy more reliable
[02:21:47] <Aero-Tec> BTW, bob cad cam had a stripped down version of solid works for $1500 I think that was what it was
[02:22:06] <ctjctj> Aero-Tec: I wish I could sell things but the software is so expensive I decided to write the software myself. Slow going. I know *how* to do most of the things I want to do. It is now just a small mater of programming it.
[02:22:32] <Aero-Tec> I was dealing with the solid work rep and then BOB cad offered me this deal
[02:22:45] -!- FinboySlick [FinboySlick!~shark@squal.net] has joined #linuxcnc
[02:23:52] <Aero-Tec> my solid works rep was shocked and also felt ripped as he could not offer me anything even close to it and he had also never even heard of that version that BOB cad was offering
[02:24:49] <ReadError> hmmmmm they have a trial apparantly
[02:24:57] <ReadError> <3 vmware esxi snapshots
[02:25:21] <ReadError> wonder if it is full featured or the gimp version
[02:28:36] <Aero-Tec> I write most code using variables and subs. like planing a surface, size of mill bit, start of x end of x, start of y and end of y, hit go and it is done all through preprogrammed sub
[02:29:05] <jdhNC> you should make a full featured conversational programming interface for me.
[02:29:06] <Aero-Tec> it is a gimp version, no 2D stuff and a few other things
[02:30:06] <Aero-Tec> maybe we should start a group
[02:30:29] <Aero-Tec> one that does programmable Gcode
[02:30:57] <Aero-Tec> just punch in some numbers and hit go
[02:31:43] <ctjctj> Aero-Tec: I'm scared to do that. I'm afraid that I'll find out that everybody else's g-code interpreter does it just a little bit differently.
[02:31:55] <jdhNC> but only one matters.
[02:32:06] <ctjctj> I'm afraid to go look and find out that o codes are only linuxcnc.
[02:32:13] <ctjctj> jdhNC: *GRIN* that is one way of looking at it.
[02:32:51] <Aero-Tec> I wrote my own code for drilling, facing reducing the dia in the lathe, boring, it is all done with subs and a few variables, punch in the values and load the sub and hit go
[02:35:26] <Aero-Tec> I used them in mach, but mach suck, no conditional branches, that made some things very difficult to program, but I was able to do it
[02:35:50] <Aero-Tec> had to think way outside the box
[02:36:00] <ctjctj> *nods* I can believe it.
[02:36:55] <ctjctj> I've not tested if you can do #31=1024 #[#31]=55 to be able to set #1024 to the value of 55
[02:37:09] <Aero-Tec> I very much look forward to using named variable and conditional branches
[02:38:07] <Aero-Tec> why not just use #1024=55
[02:38:22] <Aero-Tec> you taking a very long way around
[02:39:21] <Aero-Tec> I would have to check the manual, I am very new to EMC
[02:39:40] <ctjctj> Aero-Tec: think of a loop where #31 goes from 0 to 8 so that you can move all of a coordenate tuple in a loop rather than #31=#5061 #32=#5062... #39=#5069
[02:39:44] <Aero-Tec> in fact I just started yesterday with my lathe, mill is next
[02:40:30] <Aero-Tec> got mad at mach for the last time
[02:40:31] <ctjctj> in a fuller language it would be "for (int i=0; i<9; i++) a[i] = b[i];"
[02:40:42] <Aero-Tec> finaly made the jump to EMC
[02:41:09] <ctjctj> Aero-Tec: good for you. LinuxCNC is great. I've been playing with it for 4-5 years. Actually using it for about 6 weeks.
[02:42:30] <r00t4rd3d> o_O
[02:44:00] <r00t4rd3d> how do you play with it?
[02:44:04] <r00t4rd3d> Sim
[02:44:10] <ctjctj> Yep, sim.
[02:44:37] <ctjctj> But you don't see things the same way. Like just how important it is to be able to zero your tools *exactly* when you change tools.
[02:44:50] <ctjctj> Or how fast this thing can really make chips and move.
[02:44:55] <Aero-Tec> you know, with programmable Gcode one could do a ton of things like center of bolt pattern distance from center and number of holes, in just a few second you could have the whole thing programmed and running
[02:45:22] -!- demacus_ has quit [Read error: Operation timed out]
[02:45:22] <ctjctj> There might even be canned cycles for that.
[02:46:33] <Aero-Tec> that was just a example, but if that is a canned cycle in EMC that would be cool
[02:46:37] <ctjctj> r00t4rd3d: or another one that got me: There is no model for absolute positioning. This becomes an issue when you have motion commands that only work in a corrdenate system. I.e. does not accept a G53 prefix.
[02:46:48] <Aero-Tec> mach had no such thing
[02:46:57] <ctjctj> Aero-Tec: have you looked at some of the example nc files?
[02:47:17] <r00t4rd3d> you could have wrote that in Mandarin Chinese.
[02:47:18] <Aero-Tec> not yet
[02:47:36] <ctjctj> Aero-Tec: take a look. Lots of good exmaples.
[02:48:10] <Aero-Tec> well I very quick look, but not opened them, did open one or two
[02:48:38] <ctjctj> r00t4rd3d: the primary g code to move the cutter is "g0" and "g1" you give them a command like "g1 x3 y 4 z2" which says "move to the point (3,4,2) in a straight line at the current feed rate"
[02:48:43] <Aero-Tec> but did not look them over like I would like
[02:49:06] <ctjctj> but linuxCNC (and maybe others) has the concept of offset coordinate systems.
[02:49:17] <ctjctj> In computer graphics we call them "local coordinate systems"
[02:49:22] <Aero-Tec> I was looking for why EMC kept complaining about how I ended my Gcode
[02:50:19] <ctjctj> When you start linuxcnc you need to home your axis. This moves each axis to a known location and at that point you know the "absolute (global)" position of the cutter.
[02:50:22] <Aero-Tec> that is what Kin K is helping me with, he is looking over my code and trying to tack down what EMC does not like about it
[02:50:38] <r00t4rd3d> is it an absolute must i learn gcode?
[02:51:01] <r00t4rd3d> I perfer cp coding
[02:51:06] <ctjctj> That's what the home button in axis does. If it says "home all" it does it all automagically. If not then you jog the cutter to the right place and home each axis.
[02:51:08] <Aero-Tec> I did a quick and dirty conversion of some mach code, EMC did not like it at all
[02:51:17] <Aero-Tec> and I can not find out why
[02:51:36] <ctjctj> After that the machine/controller needs to know where your work is. That is done with "touch off"
[02:52:06] <ctjctj> you move the cutter to a place which going to be the zero for your work. You then "touch off" the x,y axis.
[02:52:13] <Aero-Tec> what is CP coding?
[02:52:25] <r00t4rd3d> Copy/Paste.
[02:52:28] <ctjctj> you don't need to learn g-code. Many people I'm sure never learn gcode. But it does make somethings much easier.
[02:52:34] <Aero-Tec> and yes it is of great help to know Gcode
[02:52:37] <Aero-Tec> lol
[02:53:16] <ctjctj> once you have touched of x,y,z you now have offsets. They are stored in a local coordinate system. G54 by default.
[02:53:25] <Aero-Tec> some just use cam to gen the Gcode
[02:53:50] <ctjctj> so now when you say "g1 x3 y2" it goes to (3,2) PLUS the G54 offsets.
[02:54:05] <Aero-Tec> but I can not imagine doing CNC and not knowing Gcode
[02:54:06] <ctjctj> This means that you don't have to put your work piece at the zero location of your machine.
[02:54:31] <Aero-Tec> you have to be able to speak the language the machines understands
[02:54:55] <Aero-Tec> that way you can tweak things and speed things up
[02:54:57] <ctjctj> r00t4rd3d: here's an example for you. You want to move your cutter out of the way for some reason. You can press keys and move the cutter head with the arrows and page up/page down till you get the cutter where you wnat it.
[02:55:42] <Aero-Tec> you know all the extra move most cam program generate? well it you know Gcode you can get rid of them
[02:55:50] <r00t4rd3d> I can use a PS2 controller to manually control my controller
[02:56:03] <ctjctj> or you can type "<F5> g53 g0z3 \rg53 g0x0y0" and send the cutter straight up and then over to the machines 0,0 location.
[02:57:03] <r00t4rd3d> how hard is it to like find a image on the net and carve into wood
[02:57:15] <ctjctj> how much do you want to pay?
[02:57:19] <Aero-Tec> if you just making one or 2 of any one thing then that is OK
[02:57:26] <r00t4rd3d> pay
[02:57:32] <r00t4rd3d> nothing
[02:57:55] <r00t4rd3d> myself im asking
[02:58:10] <Aero-Tec> but if your making thousands of one thing, trust me you will want to be able to speed it up as much as possible
[02:58:17] <ReadError> how often do you all lube your leadscrews ?
[02:58:35] <ctjctj> r00t4rd3d: there are lots of images on the net you can find and use. And emc can convert jpgs and other images to something that can be milled.
[02:58:55] <r00t4rd3d> i want to do inlays
[02:58:59] <ctjctj> But for most things you are going to want good 2d vector graphics which are harder to find.
[02:59:35] <ctjctj> in addition, if you are doing inlays you'll have to learn to make sure that you round corners correctly to let them inlay correctly.
[02:59:46] <ctjctj> Vectric has some great videos on lots of this stuff.
[03:00:04] <r00t4rd3d> I really need to finish my machine first
[03:00:11] <r00t4rd3d> my brain is over loaded with just that atm

[03:00:35] <r00t4rd3d> ctjctj, you have a pic of your machine?
[03:00:38] <ctjctj> ReadError: You got that right.
[03:00:55] <r00t4rd3d> well i am good with coding and computers/software/linux so....
[03:01:02] <Aero-Tec> your machine will have to be nice and rigid to do good inlays
[03:01:05] <ReadError> r00t4rd3d, i do linux all day
[03:01:11] <ReadError> but its like the machining part
[03:01:16] <r00t4rd3d> ive used linux for 20+ years

[03:15:13] <ctjctj> Then the FP Basic came out and used their own FP routines which didn't run as fast or as accurately as the ROM versions.
[03:15:26] <ctjctj> Did you get to play with the KIM II?
[03:15:37] <Aero-Tec> no
[03:15:37] <ctjctj> Or the Poly Science boxes?
[03:15:58] <Aero-Tec> played with a Sinclare
[03:16:25] <ctjctj> We use to fix the home built PolySci boxes. Customers would buy kit boards for memory cards for S100 bus. Then we'd have to fix them.
[03:16:50] <ctjctj> It was like $500-$1000 for an 8K bytes (that's right 8192 bytes) of memory.
[03:16:57] <ctjctj> Yeah, the Sinclare came a little bit later.
[03:18:04] <Aero-Tec> and lets not forget the old commodores the 64 and 128
[03:18:10] <Aero-Tec> they were fun
[03:18:25] <ctjctj> KIM was a cool 6502 embedded board. had 1k of memory on it. 16 key hex key pad and a 8(?) digit LED display. Plus some IO ports. We used it to do a solar house embedded controller system.
[03:18:57] <ctjctj> Yep, the Commodore 64 with the chiclet keys.
[03:19:10] <Aero-Tec> sounds very much like the Sinclare
[03:19:31] <ctjctj> KIM was 6502 and I think the sinclare was 6900 or 8080 based?
[03:20:09] <ctjctj> Yeah, Z80 based.
[03:20:39] <Aero-Tec> yep
[03:20:56] <Aero-Tec> I have some of them around here somewhere
[03:21:55] <Aero-Tec> I should look, I may still have the Sinclare round here some where
[03:22:19] <ctjctj> 6502 was running at 1Mhz but was a pipeline design with one instruction completing per cycle. The 8080/Z80 was non-pipelined and took multiple cycles to do *anything* Plus 6502 was more risc based than the z80/8080. I use to have fun getting the 6502 do things faster than those over clockec z80s running at 5Mhz (normal was 4mhz)
[03:22:26] <Jymmm> Aero-Tec: Say What? you have SOME?! As in plural???
[03:23:28] <Aero-Tec> Z80 and 8080
[03:23:30] <Aero-Tec> yes
[03:23:47] <Aero-Tec> maybe even some 6502s as well
[03:23:53] <ctjctj> Neat thing about the 6502 was that it had an imcomplete set of extra registers that you could use. I wrote some code to that was "protected" by using the extra registers. They didn't decompile and unless you had analyzed the chip you wouldn't know what they did.
[03:24:06] <Jymmm> Aero-Tec: Shhhhhh, your age is showing again, cover that up ;)
[03:24:25] <Aero-Tec> I was a tec, did repair work so I had a whack of them around
[03:24:29] <ctjctj> Well, the registers were complete. You just couldn't do everything with them because some op codes were used for strange things.
[03:24:54] <Jymmm> Aero-Tec: I'm just teasing =)
[03:25:18] <Aero-Tec> lol
[03:25:22] <Aero-Tec> no problems
[03:25:28] <Aero-Tec> yes O am a old fart
[03:25:31] <Aero-Tec> I
[03:26:10] <Jymmm> Aero-Tec: Well hurry up and make that cnc controlled walker already before you forget how to !
[03:26:41] <Aero-Tec> good old assembly, I loved programming in assembly, lost art now days
[03:27:10] <ctjctj> *grins* must be why I like doing embedded code. Even if they mostly use C
[03:27:11] <Jymmm> so it software development
[03:27:25] <ctjctj> Jymmm: that is just sad.
[03:27:33] <Jymmm> that's why there's 17,000 versions
[03:27:46] <Jymmm> 12.025.774
[03:28:22] <ctjctj> but I'm off. Likely be back tomorrow with other memory dumps and begging for help with gcode
[03:28:26] <Aero-Tec> I was thinking I should make a cool wild chair for when I get old
[03:28:43] <Jymmm> you ever notice that FF jumped from v9.0 to v10.0 to v11.0 to v12.0 ???
[03:29:07] <Aero-Tec> whats FF?
[03:29:29] <Jymmm> Aero-Tec: with self tracking so you just push one button and takes you home when our drunk
[03:29:37] <Jymmm> FF == Fire Fox
[03:29:55] <Jymmm> the web browser
[03:30:05] <Aero-Tec> I use fire fox
[03:30:25] <Aero-Tec> thought we were still talking programming language
[03:30:45] <ReadError> Jymmm, dont forget 4
[03:31:00] <ReadError> wasnt there a big jump after 4?
[03:31:24] <Jymmm> we are, I'm saying that devleopers today dont write good code, they just say "will get it in the next version" but FF has jumped MAJOR VERSIONS in the last year.
[03:31:36] <alex4nder> hey
[03:32:01] <Jymmm> no 11.2 or 11.5, straight from v11.0 to v12.0
[03:32:02] <Aero-Tec> KimK: you around?
[03:33:12] <Jymmm> Aero-Tec: make sure that the padign on your chair can be tossed in the washer and that the stuff that makes it run is IPX7 rated for water and dust proof!
[03:33:16] <Jymmm> padding
[03:33:50] <Jymmm> then you can just hose that sucker off any time!

[03:37:43] <alex4nder> anyone have a recommendation on a coolant sump pump?
[03:37:49] <Aero-Tec> not good for stairs
[03:38:29] <ReadError> alex4nder, what cam software do you use?
[03:38:33] <ReadError> to convert stl-> gcode
[03:38:47] <alex4nder> that depends on what I'm doing
[03:38:51] <alex4nder> usually I don't do that.

[03:39:09] <ReadError> pycam messes it up ;/
[03:39:20] <alex4nder> yah, I definitely wouldn't do that with STL.
[03:39:25] <alex4nder> I'd program that manually.
[03:39:37] <jdhNC> I'd drop it in cut2d and be done in 30 seconds
[03:39:54] <alex4nder> or that
[03:40:57] <ReadError> payware ;(
[03:41:03] <ReadError> is the demo full feature?
[03:41:07] <alex4nder> write the g-code yourself
[03:41:09] <alex4nder> it's easy
[03:41:27] <alex4nder> and you should learn how all that stuff works anyway
[03:41:37] <Jymmm> Aero-Tec: And whatever you do, make sure you allow for this... http://vimeo.com/31008456
[03:41:40] <ReadError> i just learned a bit of solid works today ;/
[03:41:46] <jdhNC> demo doesn't save gcode except for the demos. I bought a copy
[03:41:52] <ReadError> solidworks was very intuitive
[03:41:59] <ReadError> unlike many of the other apps
[03:42:04] <ReadError> which have a steep learning curve
[03:42:13] <jdhNC> I've never found any cad program to be intuitive
[03:42:24] <ReadError> solidworks really is
[03:42:26] <ReadError> it felt natural
[03:42:31] <ReadError> and doing what i wanted was easy
[03:43:07] <Aero-Tec> Jymmm: cool toy but not good on land. lol
[03:43:25] <alex4nder> ReadError: Looking at your drawing, I see a 180 degree arc, a 360 degree arc, a 30 degree arc (?) and 8 peckdrills
[03:43:31] <Aero-Tec> yes solid works is great, that is what I use
[03:43:33] <alex4nder> er 2 30degree arcs
[03:43:36] <jdhNC> I ran across some software this week that was even more non-intuitive. Survey software for a cesium magnetometer (boat towed)
[03:43:40] <Jymmm> Aero-Tec: Sure it is, just add water!
[03:44:30] <Jymmm> Aero-Tec: if you were wondering.... $98,000 USD
[03:44:42] <Aero-Tec> is that all
[03:45:06] <Aero-Tec> some guy made a conversion for his jet ski
[03:45:11] <Aero-Tec> worked well
[03:45:21] <Jymmm> Aero-Tec: Yep! But if you go out to havasu, you can get an hours or so for about $400, that includes training
[03:45:24] <Aero-Tec> much cheaper way to go
[03:45:51] <Aero-Tec> have you tried it yet?
[03:46:10] <Jymmm> I wish, I'd pay the $400 gladly
[03:46:28] <Jymmm> It's a once in a lifetime thing
[03:46:38] <Aero-Tec> make one
[03:47:00] <Jymmm> Nah, wouldn't use it more than once, $400 is cheaper
[03:47:01] <Aero-Tec> find a friend with a jetski and make a adapter
[03:47:28] <Aero-Tec> one hour would not be enough
[03:47:42] <Aero-Tec> would want to play longer with it
[03:47:55] <Aero-Tec> wonder what the second hour would cost
[03:48:05] <Aero-Tec> no training needed
[03:52:43] <Aero-Tec> I am off to bed soon
[03:52:58] <Aero-Tec> still feeling lousy

[05:08:45] <Connor> trying to find some good pictures of people limit switches installed...
[05:10:06] <r00t4rd3d> what controller do you have
[05:11:00] <Connor> huh?
[05:11:17] <r00t4rd3d> like a gecko or tb6560
[05:11:28] <Connor> Keling 5056
[05:12:15] <roycroft> have you tried going to images.google.com and typing "limit switch installation"?
[05:12:28] <r00t4rd3d> or youtube
[05:12:30] <Connor> looking on the cnczone right now..
[05:12:41] <r00t4rd3d> ive learned alot from youtube
[05:12:43] * roycroft notes the non-answer
[05:13:01] <Connor> but, yes, I've done goggle search too
[05:13:21] <roycroft> i just went to the google images site, typed that in, and got heaps of useful results
[05:14:09] <roycroft> but i don't know exactly what you're trying to learn from the images you're seeking, so perhaps that is not the most useful query for you
[05:14:25] <r00t4rd3d> finding someone alive on irc who has done it though is that much better
[05:14:45] <roycroft> generally, yes
[05:14:50] <Connor> I have a slew of micro switches, all wither levers.. non with rollers..
[05:15:26] <Connor> trying to see if anyone has used non roller kind.. planning on one switch for X and one for Y (center mounted)
[05:16:13] <Jymmm> Connor: WTH?! It's LIMIT switch, not CENTER switch.
[05:17:12] <Connor> Jymmm: You put switch in middle.. You put stops on either end.. and your done. ??
[05:17:29] <Jymmm> again, it's LIMIT
[05:17:52] <Jymmm> you have reached the limit, the end, there is no more.
[05:18:15] <roycroft> right - you put two switches on each axis
[05:18:36] <Jymmm> If you want a HOME switch in the middel, so be it.
[05:18:38] <Jymmm> middle
[05:19:03] <roycroft> you use all nc switches, and connect them in series
[05:19:21] <roycroft> if ever that circuit opens, you stop
[05:19:26] <Connor> Yes, I know all that.. WTF does it matter were the switch is at as long as it trips at the end of the travel ?
[05:19:57] <Jymmm> key word, END, not MIDDLE.
[05:20:00] <roycroft> a dp switch could work
[05:20:00] <Connor> We're talking a Mill, not a router..
[05:20:13] <roycroft> center closed
[05:20:16] <roycroft> left or right open
[05:20:20] <Connor> http://www.micro-machine-shop.com/RF_power_feed_limit_switch.jpg
[05:20:25] <Connor> example image.
[05:20:26] <roycroft> you could do that with one switch on each axisw
[05:21:02] -!- cmorley has quit [Ping timeout: 260 seconds]
[05:21:08] <roycroft> ok, that's a kind of nc dp switch
[05:21:30] <Connor> Is a micro or optical sensor in there.. and gets tripped in either direction.
[05:21:49] <Connor> http://media.digikey.com/photos/CK%20Comp%20Photos/11TL604,%2011TL602.jpg
[05:21:52] <roycroft> so that's what you have?
[05:22:12] <Connor> No. I just have a micro.. but I can make a enclosure.
[05:22:36] <roycroft> two switches in the enclosure, one facing right and one facing left?
[05:24:13] <Connor> No, just one. I guess I need to get some ones with rollers.. or bend the lever rounded..

[10:03:03] <Loetmichel> a bit much material for a reprap?
[10:03:27] <Loetmichel> but: nice construction!
[10:10:48] <alex4nder> so .. I made my own oil-based coolant
[10:10:55] <alex4nder> I'm wondering how well this is going to work.
[10:15:10] <Thetawaves> canola oil has been working well for me
[10:15:41] <alex4nder> you flooding your mill with it?
[10:15:52] <Thetawaves> i'll try peanut oil next, but it is more expensive
[10:15:55] <Thetawaves> yeah, flood
[10:16:00] <alex4nder> nice
[10:16:06] <alex4nder> any bacteria problems?
[10:16:23] <Thetawaves> none, there is no water in the mix.
[10:17:04] <Thetawaves> it made my cuts burr free
[10:17:09] <Thetawaves> it was amazing.
[10:17:47] <Thetawaves> i think the burs are mostly chips cold welding to the material behind the cutter, the oil flushes it away
[10:18:22] <alex4nder> what kind of pump are you using?
[10:18:37] <Thetawaves> a simple 300gph pond pump
[10:18:42] <alex4nder> nice
[10:18:43] <Thetawaves> because i already had it
[10:19:02] <Thetawaves> it pumps oil pretty well if you have a pig enough hose on the output
[10:19:07] <Thetawaves> big*
[10:19:30] <Thetawaves> for the same price you can get a positive displacement pump that will really pump oil at walmart
[10:20:08] <Thetawaves> if money is involved, definitely get the positive displacement pump
[10:20:48] <alex4nder> yah, the pond pumps I saw had a lot of bypass under any real restriction
[10:22:09] <Thetawaves> i use cooking oil because my machine is in my dining room... just feels a whole lot safer
[10:22:27] <Thetawaves> not because i need cheap oil or think it's superior cutting fluid
[10:23:18] <alex4nder> right. which machine?
[10:23:46] <Thetawaves> 3020T engraving machine

[10:24:17] <alex4nder> ah cpp;
[10:24:20] <alex4nder> er cool
[10:24:34] <alex4nder> nice and small
[10:24:52] <alex4nder> what're you doing with it?
[10:25:22] <Thetawaves> engraving... i made some designs in plate aluminum
[10:25:35] <Thetawaves> and circuit boards, lots of circuit boards
[10:25:45] <alex4nder> nice
[10:26:37] <Thetawaves> i am in the process of upgrading from 200w to 300w spindle motor
[10:26:46] <Thetawaves> :D
[10:28:01] <Thetawaves> i can fit 1/4" endmills in that thing
[10:29:56] <Thetawaves> so sorry alex4nder, what did you make your fluid out of?
[10:31:56] <alex4nder> the mix I'm going to test tomorrow is: water, mineral oil, tide ultra laundry detergent, and redline water wetter
[10:32:24] <Thetawaves> scary
[10:32:33] <Thetawaves> i was researching home made cutting fluid on google
[10:32:54] <jthornton> what are you cutting?
[10:33:03] <Thetawaves> and one of the main results was a cdc report about how this machinist got flesh eating bacteria in his hand while changing the cutting fluid
[10:33:06] <alex4nder> aluminum and steel
[10:33:32] <jthornton> for aluminum you just need some water with dish soap in it
[10:34:00] <Thetawaves> what about your machine tools?
[10:34:02] <alex4nder> jthornton: that's basically what this is
[10:34:38] <alex4nder> the mineral oil and water wetter are there to counter act rust and corrosion
[10:34:39] <jthornton> what is the mineral oil for?
[10:34:45] <jthornton> ah ok
[10:35:57] <jthornton> I use sodium nitrite in my plasma water to stop any corrosion
[10:36:18] <alex4nder> Thetawaves: you can get flesh eat bacteria from a spider bite.
[10:36:34] <Thetawaves> flesh eating bacteria is very rare.
[10:39:36] <Thetawaves> ok my mistake
[10:39:38] <Thetawaves> "Flesh-eating bacteria" is a misnomer, as the bacteria do not actually "eat" the tissue. They cause the destruction of skin and muscle by releasing toxins (virulence factors), which include streptococcal pyogenic exotoxins. S. pyogenes produces an exotoxin known as a superantigen. This toxin is capable of activating T-cells non-specifically, which causes the overproduction of cytokines and severe systemic illness (Toxic shock syndrome).
[10:39:59] <Thetawaves> and there are a few families of bacteria capable of this
[10:40:24] <Thetawaves> apparently the infection is the really rare part
[10:41:17] <jthornton> we have billions of brown recluse spiders that have a hemotoxin venom
[10:42:33] <Thetawaves> HAHA
[10:42:34] <Thetawaves> Jeff Hanneman, guitarist for the thrash-metal band Slayer, contracted the disease in early 2011. He was allegedly infected after being bitten by a spider.[22]

[13:32:01] <jdhNC> Center format arcs are more accurate than radius format arcs
[13:32:05] <jdhNC> Why is that?
[13:35:56] <ctjctj> jdhNC: Because you state explicitly the points where you want the arc to end.
[13:36:12] <ctjctj> jdhNC: whereas the other is a calculated end point.
[13:37:10] <jdhNC> ok, so the end point is more accurate, doesn't that make the radius less accurate?
[13:37:34] <ctjctj> Not really.
[13:38:02] <jdhNC> why not, the center of the arc radius is calculated.
[13:38:40] <ctjctj> Do you care if the center of the arc is off by 1/1000 in a 2 inch circle?
[13:38:52] <ctjctj> Not really, you care where the cutter runs.
[13:39:39] <jdhNC> guess I'd have to see the actual error to know if I cared.
[13:40:35] <ctjctj> They are different types of calculations is the best answer I can give. I'd have to go dig into the math a little more in order to answer better. But the gist is that using angles isn't as accurate.
[13:41:29] <ctjctj> If your angle is off by 1/1000 and your radius is 10 inches then your final point is going to be off by 1/1000 * 10 or 1/100.
[13:41:44] <jdhNC> why would your angle be off at all?
[13:42:04] <ctjctj> because you are using floating point numbers going in to sin/cos functions.
[13:43:07] <jdhNC> bah, computers are perfect!
[13:43:17] <freespace> best lie we have ever told
[13:43:19] <jdhNC> for some approximation of perfect.

[13:45:34] <ctjctj> The issue is the multiplication affect. Every point you define is off by a value less than epsilon. You can make epsilon as small as you want but the smaller it gets the harder it is to do. But anytime you can multiply epsilon your error gets that much bigger. :-(
[13:46:02] <jdhNC> I understand the math, not not sure how much it matters.

[16:09:41] <Jymmm> jdhNC: Say yo had a level, and it was off by 100th of a degree. Now, you're building a cider block wall and you use that level to make sure the wall is perfectly straight. When you build up the wall to 30 some-odd feet, it's gonna be tilted out.
[16:11:31] <Jymmm> ...as the errors are cumulative.
[16:11:36] <archivist> there is a chance you reverse the level so it should average out straight
[16:12:18] <archivist> but no one uses a level without checking it do they
[16:12:40] <Jymmm> True, especially if you happen to know that is exactly how you check the accuracy of a level, most don't =)

[19:28:14] <SolarNRG> I'm giving up on the microwave idea, I'm sure there is a way to do it, now I'm going into induction
[19:28:21] <archivist> does the microwave still heat water
[19:28:24] <SolarNRG> I can do solder with a soldering iron
[19:28:25] <SolarNRG> Yes
[19:28:27] <SolarNRG> It does
[19:28:59] <Jymmm> if you cant melt solder with a microwave, your not going to melt any other metals that I'm aware of

[19:29:39] <SolarNRG> OK FORGET microwave.... I have really tried
[19:29:45] <Jymmm> as far as induction goes, your cheapest bet is a replacment element from an induction cooktop
[19:29:55] <archivist> try woods metal

[19:56:55] <mk0> hly cow and this is not a joke. all our labs chiefs are from 40-s
[19:57:04] <archivist> Jymmm, yes
[19:57:24] <archivist> made a wooden bearing one day
[19:57:35] <mk0> they all hardly walk
[19:57:51] <alex4nder> hey
[19:58:04] <Jymmm> archivist: well, it is a moving part, so not really a fair comparison to a 100yo induction furnace
[19:58:36] <mk0> wooden bearing. you troll
[19:58:43] <Jymmm> lol
[19:58:44] <archivist> steaming tomorrow and monday
[19:58:54] <archivist> mk0, really not a joke
[19:59:39] <archivist> its the bearing for the outlet valve of the air pump
[20:00:16] <mk0> those, who operate equipment from 60-s do not ever joke
[20:00:37] <alex_joni> mk0: you were the one looking for foam?
[20:00:41] <mk0> i mean myself
[20:00:45] <alex_joni> it's in master
[20:00:53] <alex_joni> sim/axis/axis_foam.ini for an example
[20:00:57] <mk0> lookinf for foam in what sense?
[20:01:16] <mk0> nope, it was about xuyv-foam patch
[20:01:22] <alex_joni> yes
[20:01:31] <alex_joni> it's merged into master as of march
[20:01:31] <mrsun_> anyone got any good machining videos from youtube? .. maybe channels? :)
[20:01:37] <mrsun_> i need something to watch =)
[20:01:56] <mrsun_> hand machinists are the most fun to watch :P
[20:02:00] <syyl_ws> you know mr. mueller nicks videos?
[20:02:01] <mk0> hmm, i didn't see. i looked through several times but didn't see (
[20:02:06] <syyl_ws> about scraping, casting and a bit cnc
[20:02:09] <archivist> mrsun_, upset yourself with the fast tool changer on the brother cnc
[20:02:19] <mrsun_> archivist, already done ... :P
[20:02:31] <mrsun_> syyl_, seen :/
[20:02:41] <syyl_ws> :D
[20:03:07] <mrsun_> and KEFs ... and all of hoss, and all mrpete
[20:03:16] <syyl_ws> mh
[20:03:22] <syyl_ws> you could go to the shop
[20:03:30] <syyl_ws> machine something, make a video and watch that :D
[20:03:34] <mrsun_> syyl_ws, showered, naked and in bed :P
[20:03:47] <mrsun_> sleepy time here :/
[20:03:48] <syyl_ws> to much detail ;)
[20:04:03] <mrsun_> syyl_ws, pfft ... to much detail would be ... ;P
[20:04:20] <mk0> alex_joni, axis/axis_foam.ini for an example ! i read your post not carefully. Thanks!
[20:04:28] <mrsun_> syyl_ws, thats almost like a dare to say ... you know :P
[20:04:38] <syyl_ws> *runs away*

[20:04:52] <alex_joni> that's the config you might want to try
[20:05:17] <mk0> yep i will definitely
[20:05:31] <mk0> xchat shows smileys??? oh, no...

[20:21:53] <SolarNRG> Well thanks for your help and advice, I think it is not a good idea to have an induction melter as I won't be able to power it effectively
[20:22:17] <mk0> yes
[20:23:22] <mk0> and maybe solar cells too...[joking
[20:23:31] <alex_joni> In practice, foundries use between 500 and 800 KWh /mt to raise steel to a little above its melting point of 1535deg C.
[20:24:19] <Jymmm> alex_joni: Shit, my lil hand held honda generate can do 800KW, no problem!
[20:24:32] <Jymmm> and only on one gallon of gas!
[20:24:50] <SolarNRG> That's probably more power than comes into my entire home
[20:25:27] <Tom_itx> 800Kw?
[20:26:06] <mk0> do not joke with big energies, without knowing you may find yourself dead. that's really not a joke.
[20:26:21] <Jymmm> Tom_itx: do you know of any speech modules that wotk with an ardunio?
[20:26:36] <Tom_itx> txt to speech or speech
[20:26:44] <Tom_itx> i have a couple speech boards
[20:27:08] <Jymmm> Tom_itx: Something simple to replace idiot lights for the blind
[20:27:12] <Tom_itx> one is just a recorder
[20:27:37] <Tom_itx> use a buzzer and beep out morse code
[20:27:43] <Jymmm> a counter is what I'm after
[20:28:04] <Jymmm> Tom_itx: Fine, you learn braille, and I'll use CW
[20:28:41] <mrsun_> Jymmm, impossible to generate 800KW on 1 gallon of gas
[20:29:09] <Jymmm> mrsun_: Sure it is, and in a HAND HELD generator too!
[20:29:09] <mrsun_> 34 - 40KW or something
[20:29:22] <mrsun_> and thats raw heat energy
[20:29:31] <mrsun_> without counting the mechanical losses in your engine :P
[20:30:04] <Jymmm> mrsun_: Dude, it was a joke, and I said in a HAND HELD (less than 40lbs) generator
[20:30:21] <Jymmm> mrsun_: Dont be goin all MrScience on us now =)
[20:30:26] <mrsun_> Jymmm, haha =)
[20:30:44] <mk0> :DD
[20:31:00] <mrsun_> cant remember the exact kw content of gas :/
[20:31:06] <SolarNRG> 1 gallon, hmm maybe 800kw for 30 seconds!?
[20:31:21] <Jymmm> 30mS maybe
[20:31:23] <mrsun_> SolarNRG, you got about 9kw or so per liter of gasoline
[20:31:27] <mrsun_> in energy
[20:31:28] <SolarNRG> IF you had an engine efficient enough
[20:31:29] <alex_joni> Jymmm: yeah, but you don't have one mt of metal
[20:31:38] <Jymmm> mt ?
[20:31:38] <alex_joni> I assume mt is metric ton
[20:31:45] <alex_joni> which is about 2000lbs
[20:31:56] <SolarNRG> So you'll get that amount of power for less than 100miliseconds then
[20:31:58] <Jymmm> alex_joni: what do I need with all that?
[20:31:59] <SolarNRG> per litre
[20:32:01] <SolarNRG> or about half a second
[20:32:04] <SolarNRG> for a gallon
[20:32:19] <SolarNRG> This kid made a 150w induction loop
[20:32:25] <alex_joni> but 800kWh for 2000lbs means you might need only lots less for 1-2lbs
[20:32:26] <SolarNRG> Why Can't I make a 2KW loop
[20:32:31] <SolarNRG> I think that is reasonable
[20:32:35] <alex_joni> I'm sure it's not linear though
[20:32:37] <SolarNRG> But I don't understand how to make it
[20:33:09] <SolarNRG> Maybe a 2kw loop wouldn't be super duper fast at melting metals but would it not suffice?
[20:33:16] <Jymmm> SolarNRG: Dude, just do propane and a leaf blower like everyone else.
[20:33:27] <mk0> ))))
[20:33:27] <mrsun_> SolarNRG, but still ... you have still only burned 1 gallon of gas ... and that still has no more then the 34 - 40kw energy content :P
[20:33:28] <SolarNRG> I'm against using combustible gases
[20:33:48] <SolarNRG> kw is powe
[20:33:49] <Jymmm> SolarNRG: What do you think will be produced from the molten metal?
[20:33:52] <SolarNRG> kw/h is energy
[20:34:06] <mrsun_> ahh true .. im just trying to sound smart :P
[20:34:24] <SolarNRG> a toxic zinc oxide vapour
[20:34:47] <SolarNRG> I went down the all electric road with microwaves
[20:34:50] <SolarNRG> It didn't work
[20:34:54] <SolarNRG> But i'm sure induction loop will
[20:34:57] <mrsun_> god damn uranium-235 is energy dence =)
[20:35:14] <Jymmm> mrsun_: lick it!
[20:35:27] <mrsun_> 79 500 000 MJ / Kg =)
[20:35:40] <mrsun_> compared to 47.2 MJ / Kg for gas :P
[20:35:51] <Jymmm> mrsun_: Hawt Damn, think amazon carries it?
[20:35:59] <mrsun_> i would rather have antimetter
[20:36:11] <mrsun_> theoretical is 180 000 000 000 MJ / Kg
[20:36:15] <Jymmm> I'd rather have anti-matter
[20:36:41] <mrsun_> anti-mater :P
[20:36:42] <mrsun_> matter
[20:36:47] <mrsun_> antimatter!
[20:36:49] <mrsun_> wth =)
[20:36:51] <Loetmichel> hmm, but a bit difficult to contain ;-)
[20:36:54] <mrsun_> metter? .. wth is that
[20:37:01] <Jymmm> dont matter either way =)
[20:37:14] <Jymmm> mrsun_: you lick the 235, didn't you?
[20:37:20] <Jymmm> licked
[20:37:23] <mrsun_> Jymmm, im not telling
[20:37:32] <Jymmm> I think you just did =)
[20:37:36] <Loetmichel> see if he glows in the dark... ;-)
[20:37:52] <Jymmm> Cool, dead glowing skin cells!

[20:39:08] <mrsun_> Jymmm, oh :P
[20:39:09] <Loetmichel> hmm, i hop i havent bit off more than i can chew. anyone has milled slate from a Billard table?
[20:39:13] <mrsun_> thats far from what i was thinking
[20:39:13] <Jymmm> mk0: and #chemistry
[20:39:24] <mk0> :D no. he is really there
[20:39:28] <Loetmichel> i have to make the trophy stands out of an old Billard plate
[20:39:31] <Jymmm> mrsun_: perv

[20:39:40] <Jymmm> mk0: I know, and in ##chemistry too
[20:39:50] <Jymmm> mrsun_: Keep up the good work =)
[20:40:18] <Jymmm> Ok, I'm off (in more ways than one) for a bit!
[20:40:33] <mrsun_> fingers fell off?

[20:40:45] <Loetmichel> -h
[20:40:59] <mrsun_> Loetmichel, and as im swedish you think that would help me how? :P
[20:41:14] <Loetmichel> oh, sorry, i somehow have sorted you to germany ;-)
[20:41:21] <mrsun_> haha =)
[20:41:48] <mrsun_> Loetmichel, cause of the rimshot thing? ... its stuff that i think germans could do im their dirty dirty movies
[20:42:06] <Loetmichel> and sorry again, my swedish is about 25 jears not used

[20:43:26] <SolarNRG> I actually build stuff, I actually test stuff, I video what I do and I share my videos with people, how is this trolling?
[20:43:49] <alex4nder> wut
[20:43:50] <mrsun_> SolarNRG, making magnet engines etc? :)
[20:43:58] <mrsun_> magnet generators
[20:44:20] <SolarNRG> I wasn't very successful at that either mrsun, my magnets were misaligned and acted more as dampeners rather than bearings
[20:44:39] <Loetmichel> hmmm...
[20:44:47] <SolarNRG> The positioning of your holes must be very precise
[20:45:00] <Loetmichel> i dont get how ANYONE with an egineering backgound can belive in overunity machines.
[20:45:12] <Loetmichel> +b
[20:45:13] <SolarNRG> I will admit I failed to build one
[20:45:16] <Loetmichel> grrr
[20:45:19] <Loetmichel> -b+n
[20:45:21] <SolarNRG> I will also admit I have failed to melt metal in a microwave
[20:45:25] <mk0> SolarNRG, you're furthermore a grammar troll! i explode
[20:45:37] <alex4nder> SolarNRG: you actually tried the microwave? what happened?

[20:47:10] <mrsun_> omg so brittish!
[20:47:13] <mrsun_> it hurts =)
[20:47:27] <alex4nder> SolarNRG: you ever heard the term 'keep it simple'?
[20:47:33] <alex4nder> it's a good default
[20:47:42] <SolarNRG> I like rube-goldberg methods
[20:47:47] <mk0> my butt melts
[20:48:10] <alex4nder> if it's complex, it's probably not going to work
[20:48:25] <Loetmichel> SolarNRG: if it comes to overunity machines: it CANT be done. Physics lawas are loaws, not suggestions
[20:48:28] <Loetmichel> laws
[20:48:38] <SolarNRG> TBH most of my channel are failed experiments, although I can be proud that I have been honest with my results
[20:48:38] <alex4nder> well
[20:48:49] <alex4nder> Loetmichel: they're 'rules' with REALLY high probability. ;)
[20:49:27] <SolarNRG> A lump of enriched plutonium seems to defy thermodynamics, at first glance it is a rock that is hot and continues to get hotter and hotter and will stay this way for years and years and years... Then we re-wrote science to account for "nuclear fission"
[20:49:52] <SolarNRG> One energy I firmly belive in is solar steam turbine
[20:50:03] <Loetmichel> alex4nder: as far as we know they are "written in stone". Someone who will build a overunity machine has to invent a WHOLE new physics first
[20:51:00] <Loetmichel> SolarNRG: IF you can build a magnetic monopole you CAN build your overunity machine...
[20:51:13] <Loetmichel> but taht is also not supposed to happen ;-)
[20:51:32] <mrsun_> but if you take a N/S magnet and cut it in half
[20:51:34] <alex4nder> watching too much Fringe, I think
[20:51:41] <mrsun_> shouldnt you have one north pole magnet and one south pole magnet then ?
[20:51:45] <SolarNRG> I can turn 48 neodymium magnets into a sort of monopolar arrangement by bolting them all down with 3mm bolts
[20:51:51] <Loetmichel> mrsun_: ... you get 2 NS magnets with half the size
[20:52:02] <mrsun_> aww .... im not stupid ;P
[20:52:13] <mrsun_> ok maybe i am .. but not that stupid
[20:52:20] <alex4nder> ...
[20:52:20] <mrsun_> ofc you get one N magnet and one S magnet!

[21:15:42] <Loetmichel> mine has cost me about 500$ in parts
[21:15:53] <Loetmichel> and mills planetary gears just fine ;-)
[21:16:00] <SolarNRG> :o
[21:16:09] <mk0> mine too
[21:16:15] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=11702
[21:16:17] <SolarNRG> I love planetary gearboxes, you can have 2 motors or more driving a single rotor
[21:16:19] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=11711
[21:16:26] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=11714
[21:16:32] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=11714
[21:16:46] <SolarNRG> That's beautiful
[21:17:09] <SolarNRG> I don't think I'm clever enough to build one, I'd rathe buy one
[21:17:26] <mk0> buy???
[21:17:36] <SolarNRG> yeah, save up for a year
[21:17:40] <Loetmichel> i had to make the planets 3 times 'cause i didnt took the shrinking of the hollow gear into accound when pressed into the box
[21:17:41] <mk0> that;s not even 4000 pounds
[21:17:48] <mk0> it's 20
[21:17:49] <alex4nder> ReadError: the only thing that's hard is making a nice cut.. if you're doing 1/4" aluminum or something, you can't just make those arcs in one pass.
[21:18:03] <alex4nder> ReadError: so you have to employ some type of material remove strategy
[21:18:14] <ReadError> alex4nder, maybe 1/8th inch aluminum
[21:18:22] <ReadError> but i got some plastics i can use also
[21:18:23] -!- iwoj has quit [Quit: Computer has gone to sleep.]
[21:18:37] <alex4nder> ReadError: so I've been using a edge-milling strategy.. and keeping the chip load at like .002"
[21:18:42] <ReadError> i can cut the same path 3x ?
[21:18:45] <ReadError> at different depths
[21:18:50] -!- iwoj [iwoj!~iwoj@d23-16-234-107.bchsia.telus.net] has joined #linuxcnc
[21:18:53] <alex4nder> that's one strat, and it works
[21:18:54] <Loetmichel> ReadError: or 100 times...
[21:18:56] <Loetmichel> ;-)
[21:19:06] <alex4nder> but I like taking off 'tall' small pieces.
[21:19:11] -!- tlab [tlab!~tlab@c-98-223-22-156.hsd1.in.comcast.net] has joined #linuxcnc
[21:19:24] <alex4nder> so I run the cutter at the maximum depth, and shave off small pieces at a time
[21:19:28] <alex4nder> and I move at like 30 IPM
[21:19:35] <ReadError> pycam does the outside in the big hole fine
[21:19:44] <ReadError> but it doesnt want to 'drill' the other ones for some reason
[21:19:49] -!- mk0 has quit [Quit: Leaving]
[21:19:50] <alex4nder> just leave them out
[21:19:58] <alex4nder> and add them to the file manually
[21:20:01] <alex4nder> as a peck drill routine
[21:20:01] <ReadError> yea i could do another path for that
[21:20:01] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12760
[21:20:07] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12766
[21:20:11] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12773
[21:20:42] <Loetmichel> that was 300 times around ;-)
[21:20:46] <alex4nder> yah
[21:20:48] <alex4nder> that's one approach
[21:20:53] <alex4nder> I've been doing this..
[21:21:38] <alex4nder> Loetmichel: http://www.youtube.com/watch?v=ELfONtG_Zkk#t=1m
[21:21:50] <alex4nder> that's at .20 DoC
[21:22:19] <alex4nder> the chips were really consistent, and the machine really liked the constant load
[21:22:34] <Loetmichel> alex4nder: http://www.cyrom.org/pce/connectbar.avi
[21:23:09] -!- tlab has quit [Client Quit]
[21:23:20] <Loetmichel> http://www.cyrom.org/pce/lochknabbern.avi
[21:24:33] <alex4nder> cool
[21:25:04] <alex4nder> now we just need an opensource replacement to VoluMill, HyperMill, or SurfCAM. :P
[21:26:15] <alex4nder> ok
[21:26:25] <alex4nder> I'm going to go try to get 100 IPM out of my taig
[21:26:41] <ReadError> hmm
[21:26:45] <ReadError> i havnt tried any of those yet
[21:26:52] <ReadError> they have fully functional trials?
[21:27:10] <Loetmichel> alex4nder: hmmm, thats 2540mm/min, right?
[21:27:13] <Loetmichel> sounds easy
[21:27:35] <alex4nder> Loetmichel: easier said than done
[21:27:43] <alex4nder> most people run their taigs at < 60
[21:27:51] <alex4nder> w/ steppers
[21:28:01] <Loetmichel> the mini mill i have build does 3m/min if driven with 40V
[21:28:29] <Loetmichel> atm i have only 32V supply, so the maximum speed is about 2,5m/min
[21:28:49] <Loetmichel> and my steppers have only 1A/phase
[21:29:18] <Loetmichel> but: my mill has ball bnearings on round steel as ways
[21:29:26] <Loetmichel> not V-shape glide things
[21:29:55] <alex4nder> these screws are 20 TPI
[21:30:40] <ReadError> should i order some drill bits instead of cutting the holes with an endmill ?
[21:30:44] <r00t4rd3d> how can i cut tslot straight with a hacksaw?
[21:30:57] <alex4nder> r00t4rd3d: lube the saw with butter
[21:31:05] <ReadError> sounds like you need a router?
[21:31:10] <syyl_> tslot? hacksaw?
[21:31:16] <r00t4rd3d> lol
[21:31:18] <alex4nder> ReadError: endmill on that is fine
[21:31:20] <syyl_> there must be something in the air today
[21:31:47] <alex4nder> yah
[21:31:58] <alex4nder> it's cinco de mayo, everyone is drunk
[21:32:23] <r00t4rd3d> i dont drink
[21:32:33] <syyl_> you can cut a tslot with a hacksaw, if you exchange it with a milling machine and a tslot cutter...
[21:33:14] <r00t4rd3d> its only 1x1inch
[21:33:18] <alex4nder> or you could move to a buddhist monastery and bring the metal and a bastard file with you
[21:33:25] <alex4nder> and spend some time.. alone.
[21:33:51] <r00t4rd3d> i can probably do it in a vise
[21:34:05] <r00t4rd3d> and use the vise as my guide
[21:34:09] <alex4nder> alright.
[21:34:16] <syyl_> sell the hacksaw, take the money and go to a machineshop
[21:34:18] <syyl_> Oo
[21:34:23] <alex4nder> what is this for?
[21:34:30] <r00t4rd3d> just a spacer
[21:34:55] <alex4nder> why does it need to be a t-slot then?
[21:35:13] -!- iwoj has quit [Remote host closed the connection]
[21:35:14] <r00t4rd3d> cause i have an extra piece collecting dust
[21:36:06] <ReadError> alex4nder, how often do you lube the leadscrews?
[21:36:15] <alex4nder> whenever they're dry
[21:36:19] <r00t4rd3d> lol
[21:36:25] <ReadError> pretty hard to get to em
[21:36:36] <alex4nder> you mean X?
[21:36:38] <ReadError> i need a longer needle i think
[21:36:39] <ReadError> yea
[21:36:42] <alex4nder> yah, it blows
[21:38:23] <alex4nder> ok, bbl
[21:40:21] <r00t4rd3d> ReadError, goto the hardware store and buy a grease nipple and make a block
[21:41:10] <ReadError> still impossibru to get to

[21:43:06] <gene__> Hi guys, problem with g76 after I made close loop spindle speed work. It goes to a point at about the first cut depth, and sits forever waiting for a spindle index, which is there
[21:43:53] <gene__> Any idea what I might have messed up in the hal file that is stopping that?
[21:51:50] <alex4nder> r00t4rd3d: how would he make a block to grease the leadscrews on the underside of his table?
[21:55:00] -!- bedah has quit [Quit: gn8]
[22:00:03] <ReadError> so, i was talking with my dad
[22:00:11] <ReadError> he said they have whole bins of scrap metal at work
[22:00:15] <ReadError> some large pieces
[22:00:25] <ReadError> from f35 parts
[22:00:31] <ReadError> hes gonna grab me some ;)
[22:00:38] <alex4nder> nice
[22:00:39] <ReadError> surely they got some decent aluminum and such
[22:01:08] <ReadError> on problem is i wouldnt know what kind of aluminum it is
[22:01:29] <alex4nder> who cares
[22:01:34] <alex4nder> unless you're welding
[22:01:38] <alex4nder> or making critical parts
[22:01:41] <ReadError> ya
[22:01:42] <jdhNC> free is free.
[22:01:53] <alex4nder> my aluminum is the shitty household kind you get at Ace
[22:01:55] <ReadError> most aluminum i can cut at about the same rate?
[22:01:58] <alex4nder> it's like milling gummy bears
[22:02:20] <ReadError> i got a 36" of 1" bar
[22:02:26] <ReadError> i can cut a bunch of goodies with that
[22:02:29] <alex4nder> ReadError: I think you can pretty much crank your spindle speed up as high as you want.. the one worry you'll have is chips welding to your endmill
[22:02:29] <ReadError> 6061 i think
[22:02:32] <alex4nder> and smearing.
[22:02:42] <alex4nder> so a little lube goes a long way
[22:02:57] <ReadError> coolant would be nice
[22:03:00] <ReadError> but ide make a mess of it
[22:04:42] -!- petteriu has quit [Remote host closed the connection]

[23:01:57] <toastydeath> gummy aluminum is the biggest problem at low feed rates
