[02:09:50] <Deejay> moin
[06:16:42] <jthornton> 19f this morning
[06:18:39] <skunkworks_> warmer here.. (21)
[06:18:42] <skunkworks_> :)
[06:22:15] <jthornton> they are calling for snow for the weekend... yuck
[07:06:32] <Tom_itx> 19F
[07:06:35] <Tom_itx> heat wave here
[07:11:25] <mk0> here, in greenland, yup ))
[07:14:34] <PetefromTn_> Jeez man we are looking at a HIGH of 30 today here....
[09:08:59] * Loetmichel just handed the ups delivery driver a packet... he nearly let it fall to the ground if i handt catched it... should i have said that there is a APC UPS in there? a 3kVA one? ;-)
[09:10:44] <Loetmichel> ... it was only 38kg... weakling working for UPS ;-)
[09:13:53] <zeeshan> would the primary side of a vfd be considered a "non inductive/slighty inductive load"
[09:13:57] <zeeshan> almost resistive? :P
[09:15:08] <Loetmichel> depends if its power factor correted or not
[09:15:14] <Loetmichel> if not its vastly capacitive
[09:15:28] <zeeshan> <- is trying to buy a contactor
[09:15:34] <zeeshan> but needs to know if i should go for ac1 rating or ac3
[09:15:37] <zeeshan> for my current
[09:17:20] <Loetmichel> derate resistive load by at least 50%ac3 or even
[09:17:25] <Loetmichel> or the contacts will burn
[09:27:23] <zeeshan> http://www.ebay.com/itm/381048592984?_trksid=p2059210.m2748.l2649&ssPageName=STRK%3AMEBIDX%3AIT
[09:27:25] <zeeshan> bought that
[09:27:28] <zeeshan> its a little bit big
[09:27:30] <zeeshan> but will do the job
[09:29:37] <archivist> hmm are you switching a power station?
[09:29:47] <zeeshan> lol no
[09:29:49] <zeeshan> look at the ac3 rating of it
[09:29:54] <zeeshan> for 240v
[09:30:18] <zeeshan> 77A :P
[09:30:31] <zeeshan> i needed 60A-65A when compensating for power factor correction
[09:30:34] <zeeshan> on the VFD primary
[09:38:18] <cradek> people have interesting feelings about software: http://www.practicalmachinist.com/vb/haas/hacking-hsm-haas-machines-294065/
[09:40:21] <zeeshan> lol
[09:40:24] <zeeshan> i like the last post
[09:40:34] <zeeshan> hahahah
[09:45:04] <CaptHindsight> it's interesting how the training from the music industry has most people thinking theft vs copyright or contract violation
[09:45:58] <cradek> CaptHindsight: true
[09:46:46] <CaptHindsight> very funny post
[09:46:51] <cradek> CaptHindsight: people have all sorts of training that tells them they don't own things they buy
[09:46:56] <archivist> the pricing models of the sellers will get them a bad press too
[09:47:06] <zeeshan> let me clarify
[09:47:14] <zeeshan> are you guys pro "paying for software"
[09:47:15] <zeeshan> or against?
[09:47:43] <archivist> I sit on all 5 sides of the fence :)
[09:47:47] <zeeshan> hahah
[09:48:33] <zeeshan> student version of these software is so cheap
[09:48:41] <zeeshan> and almost anyone can get it :P
[09:48:51] <zeeshan> i don't understand why the need for haxin
[09:48:55] <CaptHindsight> are you guys pro "paying for software" or for killing puppies?
[09:49:38] <archivist> zeeshan, lock in method, that is only available for real students/colleges etc
[09:50:00] <zeeshan> nahh
[09:50:09] <zeeshan> autodesk inventor is the easiest to get a student version for
[09:50:15] <archivist> company I worked for started a "training company"!
[09:50:29] <zeeshan> all you do is go to their website, put a university/college name
[09:50:33] <zeeshan> and put a botch student number
[09:50:40] <zeeshan> bam, inventor for like 80$
[09:50:41] <CaptHindsight> I wasn't aware that Haas sells features via unlock codes
[09:50:47] <zeeshan> CaptHindsight: they do
[09:50:57] <zeeshan> same with fanuc
[09:51:07] <jdh> z: that is a license violation.
[09:51:15] <zeeshan> jdh too bad
[09:51:17] <zeeshan> i'm a student :)
[09:51:18] <CaptHindsight> are they the same vendor that has GPS built in so that the machine only works at the installed location?
[09:51:26] * zeeshan is student for life
[09:51:35] <jdh> if you are going to do that, why not just get a haxq0red version. It is faster to download anyway
[09:51:53] <zeeshan> cause its way easier to get owned like that especially if youre in the US
[09:52:51] <CaptHindsight> they are selling and leasing cars now with remote kill switches, if you're too late on the payments the cars stops running
[09:53:03] <zeeshan> lol
[09:53:56] <zeeshan> man
[09:54:07] <zeeshan> im kinda a bit annoyed. the senior lab engineer says "it cant be done"
[09:54:22] <CaptHindsight> I should start selling the same for appliances
[09:54:24] <zeeshan> when it comes to using a different lens, to zoom closer to what i'm trying to measure
[09:54:46] <zeeshan> i go into the manual, and it clearly says you can measure down to a 15x20 mm measuring "Volume"
[09:54:54] <zeeshan> with +/- 4mm depth of field
[09:55:04] <CaptHindsight> late on the bill for the fridge, oops too bad, no cold food for you, or the TV, microwave etc etc
[09:56:49] <CaptHindsight> when will there be a push back?
[09:57:52] <mozmck> heh, you mean you're not beside yourself with excitement over IoT?
[09:58:00] <vapula> unless you buy a license to use a good/software, you're free to hack it around. However, you're never free to make copies, and you void your warranty, like with any other good
[09:58:38] <Rab> CaptHindsight, municipal utilities often aren't allowed to disconnect vital services under some circumstances.
[09:58:52] <vapula> if you buy a license to use a good/software, you're supposed to keep it in good shape
[10:00:42] <Rab> IMO it's just simpler to use free software, even when it's inferior to corresponding payware.
[10:03:16] <mozmck> that' what I do, and I suspect why a lot of people are using things like linuxcnc.
[10:05:18] <Rab> Ironically I have a paid Cadsoft Eagle license because it was the only realistic EDA option for a free OS 12+ years ago...now friends are trying to get me to use Kicad, but it's hard to give up the productivity.
[10:05:49] <Rab> Not a big fan of Kicad.
[10:06:12] <archivist> kicad seems to be gaining momentum
[10:06:34] <mozmck> productivity? My boss switched from Orcad to Kicad and has found it better in many respects - and he's used Orcad for years.
[10:07:39] <Rab> I would like to see Kicad improve and become more of a contender...recent trial didn't leave me wanting to switch.
[10:08:11] <skunkworks> wow - I have not heard orcad for years..
[10:08:21] <skunkworks> we had a demo in the early 90's
[10:08:22] <Rab> mozmck, EDA seems to be a very personal thing. A lot of people can't seem to figure Eagle out, for example.
[10:08:26] <mozmck> It's still around.
[10:08:41] <mozmck> I tried Eagle for a day and gave up when I found Kicad.
[10:08:45] <CaptHindsight> I've had Orcad since V1. Most vendors supply us with Orcad schematics. They were purchased by Cadence
[10:09:08] <jdh> the sparkfun eagle tutorial did wonders for me.
[10:09:08] <archivist> I used PCAD for years
[10:09:09] <mozmck> I have known several long time EDA guys who have switched to kicad.
[10:09:38] <mozmck> It has it's quirks, but it is much better than it used to be. The push and shove routing now is pretty nice.
[10:10:31] <mozmck> I'm not wild about the way it gets footprints from Github by default, but you can change that and install them locally.
[10:10:40] <Rab> Yeah, that's insane.
[10:11:32] <archivist> the other insanity is having outdated foot prints locally
[10:11:43] <archivist> you cannot win
[10:12:02] <CaptHindsight> Inetl/AMD/ TI etc still supply Orcad Capture and Spectra/Allegro PCB files with reference designs, sometimes I see Altium files
[10:12:04] <mozmck> heh! outdated doesn't matter if they are correct.
[10:12:11] <Rab> I assume there's got to be a way to make designs depend on a bundled local copy of footprints, so they don't break on other people's installations?
[10:12:52] <mozmck> When you install them locally you can update them any time you want from Github. It just doesn't do it every time you open the pcb editor.
[10:13:31] <Rab> mozmck, agreed...I don't trust anybody else's footprints by default, with Eagle or anything else.
[10:13:53] <mozmck> The footprints are saved in the pcb file.
[10:14:28] <CaptHindsight> can you import gerbers into Eagle or Kicad?
[10:14:43] <mozmck> You can actually get a pcb file and save footprints out of it if you don't have them in your local libraries.
[10:14:53] <Rab> CaptHindsight, not AFAIK.
[10:15:04] <mozmck> there is a gerber import in kicad - I've used it.
[10:15:40] <Rab> mozmck, does it generate nets from plotted paths? Or what?
[10:15:49] <mozmck> it was pretty helpful bringing an older board over I needed to retain some of the layout.
[10:16:08] <CaptHindsight> do you still have to match trace lengths manually?
[10:16:28] <mozmck> No net, just pcb.
[10:16:54] <mozmck> CaptHindsight: I *think* so - but I'm not sure. I've never had to do that yet.
[10:18:20] <CaptHindsight> somebody was talking about a 1.6GHz DDR3 layout and they matched them all manually
[10:18:26] <CaptHindsight> not my idea of fun
[10:18:41] <mozmck> sounds tedious!
[10:30:55] <ssi> I like eagle; it was a learning curve, but once I really learned it well it's pretty good
[10:35:23] <zeeshan> hey guys
[10:35:35] <zeeshan> i need to put 0.005" diameter dots
[10:35:39] <zeeshan> about 0.020" apart
[10:35:44] <zeeshan> white dots
[10:35:46] <zeeshan> what do you suggest?
[10:36:00] <jdh> cnc dot applique
[10:36:27] <zeeshan> hehe
[10:36:27] <cradek> how many times do you need to do it?
[10:36:36] <zeeshan> grid of them
[10:36:39] <zeeshan> over a 2"x2" span
[10:36:44] <cradek> eek
[10:36:48] <Rab> Mill dimples w/conical cutter, fill with paint?
[10:36:56] <cradek> that's not a bad idea
[10:36:58] <zeeshan> other option is using a speckle pattern
[10:37:01] <cradek> if it's very flat that might work
[10:37:05] <zeeshan> yes its very flat
[10:37:14] <zeeshan> rab i was thinking of a stencil too
[10:37:24] <Rab> zeeshan, what material?
[10:37:29] <zeeshan> it just i think needs the extra hassle of cleaning it after
[10:37:36] <zeeshan> its a polymer
[10:37:43] <pcw_home> paint with white photo-resist
[10:37:45] <zeeshan> http://1.bp.blogspot.com/-V_6Zl8xRZZE/TygOEUyCZtI/AAAAAAAAAcU/fKVCc_7MJIE/s320/SpeckleInPlane.tiff
[10:37:51] <zeeshan> honestly a speckle pattern like this
[10:37:56] <pcw_home> expose to pattern/develop
[10:37:56] <zeeshan> (inverted so white dots)
[10:37:58] <zeeshan> would work really well too
[10:38:13] <zeeshan> PCW: EXCEllent
[10:38:24] <zeeshan> so basically photo etching
[10:38:26] <pcw_home> speckle spray paint?
[10:38:49] <zeeshan> pcw_home: the paint can i have seems to spray big dots
[10:38:53] <zeeshan> im thinking its something to do with the nozzle
[10:38:58] <zeeshan> and my technique
[10:38:59] <pcw_home> or industrial ink jet
[10:39:06] <Rab> zeeshan, what are the speckles for?
[10:39:21] <zeeshan> http://i.imgur.com/ZGgDoQz.png
[10:39:25] <zeeshan> notice the dimple? :P
[10:39:30] <zeeshan> http://i.imgur.com/NhXnKsa.png
[10:39:51] <zeeshan> im trying to use aramis to pick up some changing dimples (my smp films are "self healing")
[10:39:56] <zeeshan> so i need to track the change over time
[10:40:04] <zeeshan> but if you look at the analysis
[10:40:07] <zeeshan> you can see missing parts
[10:40:19] <zeeshan> cause the software can't pick up the facets cause my pattern is too crappy
[10:40:43] <zeeshan> its a combination of pattern too crappy and not enough zoom i'm thinking
[10:41:10] <pcw_home> there are inkjet printers that can do this
[10:41:21] <pcw_home> (not cheap though)
[10:41:36] <zeeshan> even if i have to send out my samples to get em speckled
[10:41:38] <zeeshan> im willing to do that
[10:42:04] <zeeshan> i'm going to try to get a different nozzle
[10:42:15] <zeeshan> then if that fails, try photo paint
[10:42:27] <zeeshan> if that fails, same stencil with paint
[10:43:22] <zeeshan> pcw_home: google isnt coming up with speckle ink jet
[10:45:10] <zeeshan> hey what about silk screening?
[10:45:15] <zeeshan> using the same stencil
[10:45:31] <Rab> That's stenciling.
[10:45:50] <zeeshan> i havent seen the process before
[10:45:55] <zeeshan> looks like they just need a stencil?
[10:46:05] <Rab> You could use a silkscreen burned with your pattern, but since it's simple dots I think you might be better off with a stencil.
[10:46:19] <zeeshan> i like the idea of burning
[10:46:28] <zeeshan> that removes the possibility of the paint rubbing off during the test
[10:46:42] <Rab> By burned I mean photoexposed resist.
[10:48:00] <Rab> Silkscreen uses resist on a fine mesh. Paint penetrates mesh but not resist: http://en.wikipedia.org/wiki/File:Ssc.jpg
[10:49:08] <Rab> So it's inherently limited in resolution. Obviously there are high-resolution industrial silkscreening processes, eg PCB mask/silk.
[10:49:13] <[cube]> Laser printer on PnP blue as resist, 8.5x11 tiling pattern?
[10:49:40] <zeeshan> i knew you guys would know some techniques
[10:49:44] <zeeshan> you pcb experts
[10:49:58] <zeeshan> when i got told "you can't do any better than a speckle spray can pattern"
[10:50:02] <zeeshan> i refused to believe that
[10:50:08] <dgarr> zeeshan: dots? halftones using conical cutter, depth controls diameter: http://www.panix.com/~dgarrett/phpv2/02-Halftones/
[10:50:13] <Rab> Yeah, that's a crock.
[10:50:41] <zeeshan> dgarr: i dont have a size perspective
[10:50:45] <zeeshan> how big is that wood part?
[10:50:45] <Rab> dgarr, neat!
[10:51:12] <dgarr> overall diam is about 3 in typ, larfest dot diam 0.040 typ
[10:51:35] <zeeshan> 1mm dots hmm
[10:51:42] <[cube]> if you wanna go budget, you could lay out a roll of dollar store rubber grip mat and spray paint over it
[10:51:44] <Rab> zeeshan, the governing question is, what's the minimum reliable penetration you can get with a conical cutter.
[10:52:07] <[cube]> http://images.esellerpro.com/2347/I/264/89/antislip%20mat.JPG
[10:52:14] <zeeshan> cube too big
[10:52:18] <zeeshan> the dots gotta be max 0.005"
[10:52:26] <[cube]> ah
[10:52:27] <zeeshan> 0.12mm
[10:52:52] <Rab> You could print out your pattern and poke holes in the paper with a pin. Use that as a paint stencil.
[10:53:04] <CaptHindsight> zeeshan: how thick are they?
[10:53:06] <zeeshan> Rab: i bet if its sharp you can do consistent depth
[10:53:15] <zeeshan> CaptHindsight: what do you mean
[10:53:17] <JT-Shop> dgarr that is amazing
[10:53:20] <Rab> Overhead transparency film prob give a cleaner result.
[10:53:31] <zeeshan> rab ROFL
[10:53:33] <zeeshan> thats an excellent idea
[10:53:46] <CaptHindsight> zeeshan: photopolymer and a projector
[10:54:09] <Rab> dgarr, impressive that it's mapped consistently over a curved surface.
[10:55:15] <CaptHindsight> zeeshan: how thick are the parts that you need to nark?
[10:55:26] <zeeshan> like .080"
[10:55:48] <CaptHindsight> how many parts?
[10:55:56] <zeeshan> not sure yet
[10:56:10] <CaptHindsight> ballpark 10, 100, 100k
[10:56:15] <zeeshan> 20
[10:56:20] <ssi> http://atlanta.craigslist.org/nat/bfs/4759412643.html
[10:56:20] <ssi> neat
[10:56:45] <CaptHindsight> photopolymer and dlp projector
[10:56:52] <Rab> dgarr, is this your site? Really cool pieces!
[10:57:00] <jdh> ssi: we have tube straightners that look like huge versions of that. They are amazing to watch run
[10:57:34] <ssi> I bet
[10:58:05] <CaptHindsight> zeeshan: coat the parts with a white photopolymer, then you project the pattern onto the surface, and then rinse away the uncured resin
[10:58:26] <zeeshan> CaptHindsight: what kind of company will have this equipment?
[10:58:40] <CaptHindsight> you can use any DLP projector
[10:59:06] <zeeshan> so i put this photopolymer on the surface
[10:59:13] <zeeshan> then basically send an image for a little while from a dlp projector
[10:59:22] <zeeshan> (speckle pattern maybe)
[10:59:25] <CaptHindsight> yes, you project for 2 seconds
[10:59:33] <zeeshan> hmm.. sounds simple :P
[10:59:43] <CaptHindsight> any pattern than you can put on the screen
[10:59:53] <CaptHindsight> the projector is a display
[10:59:54] <zeeshan> resolution is good as the dlp
[11:00:37] <CaptHindsight> yes, if it's a 1024 x 768 projector then you just divide the projected area by the pixel res
[11:01:50] <CaptHindsight> so 2" (50.8mm) / 1024 = 50microns per pixel
[11:02:31] <zeeshan> thats pretty damn good
[11:02:41] <CaptHindsight> your dots are ~127um
[11:03:02] <zeeshan> whats the name of a commonly used photopolymer?
[11:03:36] <CaptHindsight> I make them. I can send you some.
[11:03:45] <zeeshan> :D
[11:03:46] <CaptHindsight> you won't need much
[11:04:20] <zeeshan> let me try just simple nozzle change
[11:04:23] <zeeshan> and ill try your method next
[11:05:27] <CaptHindsight> or you could use a syringe and nozzle to dispense the drops
[11:05:50] <CaptHindsight> then cure in sunlight
[11:06:23] <CaptHindsight> or led flashight <420nm
[11:07:12] <CaptHindsight> or a pneumatic valve and nozzle
[11:07:22] <JT-Shop> dgarr, I have a persimmon tree that didn't do so well this year. It measures 24" in circumference waist high. Is it big enough to do anything with?
[11:10:18] <roycroft> persimmon wood is awesome
[11:10:27] <roycroft> it's a beautiful wood, very dense, and really tough
[11:10:53] <roycroft> i would use it to make mallets and perhaps wooden plane bodies
[11:11:19] <roycroft> traditionally it was used for golf club heads
[11:14:16] <dgarr> JT-Shop: that is a good size, the problem is always getting it dry without splittting, i only make small stuff now days (largest dimension under 10 in)
[11:15:25] <JT-Shop> do you have a way to dry the green wood?
[11:17:41] <JT-Shop> a medium flat rate box is 11" x 8 1/2" x 5 1/2"
[11:17:54] <dgarr> no kiln, just process green cut wood immediately, cut out the pith, cut blocks to size, coat end grain with an endgrain sealer, take your chances
[11:19:35] <CaptHindsight> zeeshan: since you are measuring distortion you could print a crosshatch over the entire surface, it would be easy to measure any change
[11:21:20] <tjtr33> dgarr, those are beautiful. cnc? i found this http://www.halftone.com.br/
[11:22:06] * JT-Shop heads inside for some rabbit food
[11:25:16] <dgarr> tjtr33: i had not seen that site, but method is same, my machine is xzc and can apply on a curved surface, so a little different
[11:25:55] <tjtr33> are the holes drilled normal to the surface? do you use some software?
[11:27:38] <dgarr> not normal since it is only a 3 axis machine, but curvature is modest so it doesn't matter, i write the code: just drill depth proporional to dot diameter
[11:28:12] <tjtr33> i've done lithophanes, this looks a _lot_ quicker :) thanks!
[11:30:24] <ssi> got dacron stretched on the seat bottom frame last night
[11:30:24] <ssi> https://pbs.twimg.com/media/B2au4V3IQAAFHeu.jpg:large
[11:34:00] <seb_kuzminsky> dgarr: hi, thanks for your work on jog no feed-override, can you please put it in 2.7 but not in 2.6?
[11:43:31] <ReadError> hm crap
[11:43:41] <ReadError> is there a way to return to a previous touchoff?
[11:44:24] <Connor> You know the number ?
[11:45:00] <Connor> It would be nice if lcnc kept a touch-off history..
[11:45:04] <Connor> I've had that happen a few times.
[11:45:24] <Connor> have the wrong axis selected when you touch off.
[11:45:40] <Connor> typically happens with my Z because I'm having to raise and lower it..
[11:48:57] <ReadError> well basically, i re-touched off (was supposed to be z)
[11:49:02] <ReadError> but it was actually x
[11:49:11] <ReadError> ran, came back a mess ;9
[11:49:26] <ReadError> just hit some top clamps, not a big deal
[11:49:45] <ReadError> i can try to use the drill hole
[11:49:57] <ReadError> but was just wonderin if there was a better/easier way
[11:49:59] <Connor> Yup.. that's the exact thing I've done.
[11:50:03] * jthornton just made a touch off Z button so no mistooks can be made
[11:50:10] <seb_kuzminsky> ReadError: there's not currently a way to do that, sorry
[11:50:39] <Connor> You need to re-indicate using a edge finder if measurements are critical.
[11:50:49] <seb_kuzminsky> but it's a good idea, and if you wanted to open a feature request for it go here: http://sf.net/p/emc/feature-requests
[11:51:08] <ReadError> would be a lovely feature, its not the 1st time ive done it
[11:51:13] <seb_kuzminsky> this would be a GUI issue, so make sure to include in the feature request which GUI you're using
[11:51:15] <ReadError> probably wont be the last
[11:51:42] <Connor> I would love a /2 function too..
[11:52:00] <seb_kuzminsky> Connor: what do you mean?
[11:52:00] <Connor> so you can indicate on left side of part.. touch off.. indicate on right hand side of part...
[11:52:13] <Connor> then hit /2 function to get the center.
[11:52:17] <seb_kuzminsky> you can use math in the touch-off dialog
[11:52:36] <seb_kuzminsky> touch off X=0 on the left, go indicate the right, and touch off (whatever the DRO says)/2
[11:52:49] <seb_kuzminsky> i use that all the time
[11:52:50] <Tom_itx> what happened to the machinists that use x y as a reference and did a bit of math?
[11:53:11] <Connor> Tom_itx: Nothing.. but.. time is money..
[11:54:07] <Tom_itx> it's not that difficult to know your block size and touch off one corner
[11:54:46] <Connor> I'm using a new method that increases the accuracy by x2 on finding the edge.
[11:54:50] <archivist> you often cannot get the vernier on to a part when in the machine
[11:55:26] <Connor> indicate on both sides, divide by 2. cut's the error down by 1/2
[11:55:58] <cradek> you can type an expression into the AXIS touch off box, so if you want /2 type /2
[11:56:18] <Connor> Didn't know that.
[11:56:19] <cradek> that way you don't need a special button for each possible divisor
[11:56:19] <jthornton> http://linuxcnc.org/index.php/english/forum/40-subroutines-and-ngcgui/18421-probe-for-center-of-material
[11:57:15] <Connor> Okay... looking for a good ball end mill.. .25" Will be running it in cast iron.. how many fliutes? Finish.. Brand ?
[11:57:17] <archivist> try touching off this :) http://www.collection.archivist.info/archive/DJCPD/PD/2013/2013_08_11_bevel/IMG_1632.JPG
[11:57:35] <Rab> Tom_itx, it's difficult if your workpiece isn't flat. I've been engraving Hammond die-cast boxes, which are very poor tolerance-wise...often have to measure several different points on the lid and try to average, per-box.
[11:59:48] <Tom_itx> i can see that. we ran forgings alot and finding an average fixture location sometimes took a bit of thought
[12:00:21] <archivist> I found the Z error by looking at the offset of the grooves on the part under a microscope
[12:01:14] <Connor> So, any recommendations on the ball endmill ?
[12:01:31] <Connor> Milling oil groves in my saddle
[12:08:16] * SpeedEvil puts on some appropriate country and western.
[12:11:09] <Loetmichel> *HA* operation: success! ... patient: lives! ... lets see how long that ecig lasts now... "2200mAh" (more like 1000mah) out, 2900mAh sony in... ;-) -> http://www.cyrom.org/palbum/main.php?g2_itemId=15374&g2_imageViewsIndex=1
[12:12:21] <ssi> lol nice
[12:18:02] <t12> ecigs have become really popular here
[12:18:20] <t12> all the young programmers now stand in circles on the corners using them instead of cigs
[12:23:37] <Loetmichel> its less dangerous to health for sure.
[12:23:49] <Loetmichel> and less annoying to the bystanders either
[12:23:52] <Loetmichel> and cheaper...
[12:24:12] <Loetmichel> and i am dowm from 18mg/ml nicotine to 6mg/ml nicotine in about a year
[12:24:26] <Loetmichel> another half and i can try to quit it altogether
[12:26:23] <SpeedEvil> yeah - it makes ingesting nicotine go from about as dangerous as competitive motorbike racing to comparable with coffee
[12:26:53] <SpeedEvil> i'm almost at the point I'd class attempts to ban e-cigs as manslaughter.
[12:31:37] <jdh> why not just use patches
[12:31:54] <jdh> or get a insulin pump like thing to pump it straight in.
[12:34:44] <Loetmichel> jdh: because patches dont work
[12:35:02] <Loetmichel> tried quitting with paches and "cold" multiple times
[12:35:12] <Loetmichel> only the e-cig did the trick.
[12:35:33] <Loetmichel> because most of the addictance is behavior, not real cold turkey
[12:36:01] <Loetmichel> and the e-cigs are simialr in use to real cigs, so you dont have to change bahaviour abruptly
[12:36:53] <Loetmichel> ... i still caught myself on the balcony with the ecig in one hand and alighter in the other multiple times the first weeks after switching ;-)
[12:36:55] <jdh> so your nicotine lowering isn't modifying your behaviour though
[12:37:32] <Loetmichel> you could say that
[12:37:47] <jdh> so, how fucking stupid do you have to be to be <40 or so and smoke?
[12:37:47] <Loetmichel> still its better than smoking the real thing ;-)
[12:38:10] <Loetmichel> hmm, no idea, i smoke since 12, and am now 45
[12:38:49] <Connor> Okay... so, no one can recommend a good .250" Ball nose endmill for cast iron ? :(
[12:39:20] <jdh> Connor: pretty much any HSS?
[12:39:29] <jdh> why not 1/8" for an oil channel?
[12:39:53] <Connor> jdh: Just going with what other's have used..
[12:40:03] <Connor> and I've heard the Cast Iron can be hard on endmills
[12:40:11] <Connor> or at least ball nose
[12:40:38] <jdh> I have only done the saddle on mine and it cut great
[12:40:51] <jdh> 0.5" flat mill though
[12:41:15] <jdh> you could do it with a knife or a scribe
[12:41:20] <Connor> jdh: Something about the way the bottom for the end mill works..
[12:41:31] <Connor> kinda scrapes instead of cuts..
[12:52:03] <_methods> gc1620 pluramill maybe
[12:52:46] <_methods> http://www2.coromant.sandvik.com/coromant/pdf/Metalworking_Products_061/main_d_18.pdf
[12:53:03] <_methods> the gc1620 is for iso k materials
[13:01:15] <Loetmichel> i know some bold people that are extremly boring
[13:01:29] <Loetmichel> dont know if it works the other way around
[13:03:24] <jdh> I ordered some cast iron last time I got some online metals stuff. I should try a few of mine.
[13:04:04] <jdh> 25% off orders $100 or more with code if anyone wants a code
[13:07:46] * SpeedEvil suspects shipping may be an issue.
[13:14:35] <jdh> it's not too bad for me.
[13:14:38] <jdh> and pretty speedy
[13:23:32] <SpeedEvil> yeah - UK
[14:01:48] <LeelooMinai> Hmm, what are the rules inside HAL files for in/out? It seems that from what perspective they are in or out changes depending on the context.
[14:02:12] <LeelooMinai> For example: http://i.imgur.com/5nF74sg.png
[14:04:30] <LeelooMinai> Seems like OUT there means "out of the component", right?
[14:04:38] <cradek> right
[14:04:52] <cradek> out of the component, to "halspace"
[14:05:08] <cradek> input-14 is the name of a wire or a screw or something on the hardware
[14:06:11] <LeelooMinai> Ok, also what are entries that look like [AXIS_1]DIRSETUP ? Are they going to be replaced by the GUI or something?
[14:06:53] <LeelooMinai> (they are inside my hal file)
[14:07:35] <LeelooMinai> Here's how they look: http://i.imgur.com/B0US7rI.png
[14:07:50] <cradek> that syntax means get the value from the ini file
[14:08:38] <LeelooMinai> What's the purpose of this separation?
[14:09:16] <cradek> some people like all the configurable tuning constants in the ini file
[14:09:38] <LeelooMinai> a, I see, so hal would describe non-changing hardware?
[14:10:24] <cradek> I'm not qualified to say how people like to use it
[14:12:06] <LeelooMinai> Hmm, my guess is that hal is supposed to be a "model" of all the hardware wired together, and ini file a way to adjust parameters for components
[14:12:27] <cradek> that's plausible
[14:12:55] <LeelooMinai> Ok, thx, I can roll forward then:)
[15:59:11] <Deejay> gn8
[17:03:27] <zeeshan> CaptHindsight you there?
[17:05:26] <CaptHindsight> http://3dprintingindustry.com/2014/11/13/flux-3d-printer-kickstarter/ heh it has a milling head module
[17:05:56] <CaptHindsight> now you can mill sour cream with <1" precision!
[17:13:20] <andypugh> Not _too_ sour, though :-)
[17:14:17] <CaptHindsight> why didn't I ever think of using magnets to hold my spindle?
[17:16:40] <CaptHindsight> zeeshan: I'm about to be gone
[17:17:29] <andypugh> Keith Fenner is selling a magnetic widget for holding a plasma torch. But that’s a genuinely good idea.
[17:19:54] <andypugh> Looking at it, I really like the magnet/ball joints on the Flux. That’s a clever idea. But perhaps not for milling.
[17:22:47] <Tom_itx> magnets hold the surface keyboard & charge plug in place
[17:23:14] <zeeshan> capta we'll talk later
[17:53:33] <Rab> The magnets are clever, but they aren't bearing surfaces. I'm skeptical of any serious longevity.
[17:55:15] <Rab> Reminds me of the sort of audacious flourish you see from design students who missed out on materials science.
[17:57:00] <Rab> Like that recent cartesian 3D printer which cantilevered all the axes through a series of hobby servo shafts.
[18:01:10] <JT-Shop> so if you hit a pop up with the plasma it just falls off
[18:11:32] <JT-Shop> LeelooMinai, http://linuxcnc.org/docs/html/hal/basic_hal.html
[18:21:48] * JT-Shop wanders inside now
[18:50:48] <andypugh> Rab: Well, the bearings will always be backlash-free. Eventually the bearing surface will be large and spherical, so the wear rate will reduce (though re-calibration might be needed). I think it might work rather well. If it doesn’t then the principle would also work with cast-iron cups rather than directly into the magnet, and hardened steel / cast iron pairs last really well in old-school lathe spindles.
[18:51:47] <andypugh> The ball/magnet idea has been used for quite a long time in the Renishaw test bar system.
[18:52:16] <andypugh> http://www.renishaw.com/en/test-theory-and-practice--6818
[18:52:46] <andypugh> (In fact the 3D printer might be in breach of a Renishaw patent)
[18:55:04] <zeeshan> so i didnt use the din rail adapters for the 7i77
[18:55:15] <zeeshan> then a vision came to me
[18:55:22] <zeeshan> https://www.flickr.com/photos/128539016@N05/15790564825/
[18:55:33] <zeeshan> https://www.flickr.com/photos/128539016@N05/15605738830/
[18:55:37] <zeeshan> din mounted comp power supply!
[18:55:37] <zeeshan> :D
[18:58:05] <andypugh> I was offered the chance to buy a few more of these https://picasaweb.google.com/lh/photo/AXPmMc9GjIwEuk-7UFsH6dMTjNZETYmyPJy0liipFm0?feat=directlink (24V 2kW supply). The guy wanted £20 each. I can’t recall why I didn’t bite his hand off.
[18:58:50] <zeeshan> thats a lotta power
[18:58:58] <zeeshan> the big ass blue one?
[18:59:02] <andypugh> (the second PSU underneath is now gone, all the other DC voltages are now from the 24V suply via little DC-Dc converters.
[19:03:48] <andypugh> Actually, I might be wrong, perhaps it is only 500W. Even then they are £400 new.
[19:04:08] <andypugh> (So I should have bought all 6 he was offering)
[20:55:19] <jdh> yep.
[20:55:56] <zeeshan> yep?
[20:56:10] <renesis> never.
[20:57:13] <jdh> nope
[21:12:10] <PetefromTn_> https://www.youtube.com/watch?v=vA0k8i9VPNA This is an impressive little benchtop mill I have never seen before. I like the rotary unit too.
[21:17:00] <tjtr33> PetefromTn_, i thinks its a Mactep MC51, seen 'em before, very nice.
[21:17:07] <Tom_itx> yeah i wouldn't mind that sitting in my garage
[21:17:24] <PetefromTn_> I like the base of the column on it
[21:17:26] <zeeshan> PetefromTn_: hvac status?
[21:17:30] <tjtr33> SMithy had a similar machine when the linuxcnc fest was held there, umpteen years ago
[21:17:36] <PetefromTn_> It is like what an RF45 should have been LOL
[21:17:48] <PetefromTn_> zeeshan You would not believe it man
[21:17:59] <zeeshan> didnt work? :/
[21:18:00] <PetefromTn_> I took that damn drawing all over town
[21:18:21] <PetefromTn_> everyone wanted an arm and a freakin' leg to cut and bend the damn thing
[21:18:28] <zeeshan> let me guess
[21:18:29] <zeeshan> 500$?
[21:18:37] <PetefromTn_> so I decided to just buy some sheetmetal and make them
[21:18:59] <PetefromTn_> I did have to shorten the drawing because the only sheetmetal I could find reasonably priced was 24x36
[21:19:19] <PetefromTn_> so after shortening them enough to add in the damn tabs for joining it to the existing ducting
[21:19:29] <PetefromTn_> I have a drawing to work from now.
[21:19:41] <PetefromTn_> I got enough to make both of them I think
[21:19:53] <zeeshan> sweet man
[21:19:55] <PetefromTn_> so tomorrow morning we will be laying it out and bending it here in the shop
[21:19:57] <zeeshan> definitely post some pics of them when youre done
[21:20:06] <zeeshan> it's kind of a cool shape
[21:20:07] <zeeshan> hehe
[21:20:11] <zeeshan> especially with the offset
[21:20:28] <PetefromTn_> I ALMOST got on here and asked you if you could make them again in 23 or 22 inch length but I think I have the drawing modified correctly
[21:20:35] <Tom_itx> PetefromTn_ i needed a part just like that video is cutting a while back
[21:21:03] <PetefromTn_> yeah they will probably not be all that pretty when I finish them because I will not have access to a proper bender
[21:21:16] <PetefromTn_> and I am going to have to lay it out all by hand
[21:21:27] <zeeshan> it might be worth printing it out on a plotter?
[21:21:28] <PetefromTn_> but it will be worth it to save the cost of having them made
[21:21:31] <zeeshan> do you guys have a staples there?
[21:21:38] <PetefromTn_> I wish I had a damn plotter LOL
[21:21:40] <PetefromTn_> sure
[21:21:41] <zeeshan> its like 5-6 bux here to print it out on a plotter
[21:21:42] <zeeshan> up here
[21:21:44] <Tom_itx> http://tom-itx.ddns01.com:81/~webpage/temp/thread1.jpg
[21:21:44] <zeeshan> @ staples
[21:21:53] <PetefromTn_> it is like 24x28"
[21:21:53] <XXCoder> wookdgears has something called bigprint program
[21:21:53] <zeeshan> it'll save you a shitload of time
[21:21:57] <Tom_itx> looks quite similar to the part in the video
[21:22:04] <XXCoder> it uses regular paper to make large print areas
[21:22:07] <zeeshan> PetefromTn_: another thing ive done
[21:22:11] <zeeshan> is cut it intos ections
[21:22:15] <zeeshan> and joined the papers together
[21:22:21] <zeeshan> kinda like XXCoder is saying
[21:22:22] <PetefromTn_> Tom_itx That looks like a cool acme thread or somethign
[21:22:24] <zeeshan> but manually
[21:22:38] <Tom_itx> 3 tpi
[21:22:46] <XXCoder> make sure to make it overlap a little so you has room to tape
[21:22:47] <Tom_itx> regular thread
[21:22:49] <XXCoder> edge to edge sucks
[21:22:53] <PetefromTn_> ya know I may call them and ask them what they would charge to print the sucker
[21:23:19] <Tom_itx> ~1.25 diameter or so
[21:23:26] <PetefromTn_> I am going to add tabs on both pieces
[21:23:38] <PetefromTn_> Oh yeah I also cut it in half so I can make it in two halves
[21:24:05] <PetefromTn_> and I shortened it enough to add in the joining tabs for where it will intersect the original ductwork
[21:24:27] <PetefromTn_> what sucks is it is cold as shit here right now
[21:24:37] <PetefromTn_> tomorrow is not supposed to be much better.
[21:25:00] <PetefromTn_> so I will be having to do it all in the shop as much as possible then taking it outside.
[21:25:45] <PetefromTn_> I was looking at one of these machines today. Wish I had some spare change to buy one.
[21:25:51] <PetefromTn_> http://www.northerntool.com/shop/tools/product_623_623
[21:26:02] <PetefromTn_> Thanks for the idea of printing it at staples
[21:26:08] <PetefromTn_> that will make it a lot easier
[21:26:29] <zeeshan> i was suprised at how cheap they were to print out big drawings
[21:26:42] <zeeshan> but they're still not as cheap as free :(
[21:26:55] <PetefromTn_> yeah if it is like $5 It would be worth it just so I don't mis measure the shit.
[21:27:14] <XXCoder> yeah them sheets is expensive. $5 is worth it
[21:27:25] <zeeshan> isnt hvac stuff
[21:27:29] <zeeshan> aluminized sheets?
[21:27:36] <zeeshan> aluminized steel
[21:27:39] <zeeshan> or is it aluminum
[21:27:42] * zeeshan doesnt know
[21:27:50] <PetefromTn_> no its galvalized steel sheet
[21:28:04] <zeeshan> is it more expensive vs mild steel?
[21:28:14] <Tom_itx> about the same
[21:28:19] <Tom_itx> maybe a bit more
[21:29:01] <PetefromTn_> actually it was not that expensive
[21:29:11] <PetefromTn_> the 24x36 sheet was less than ten bucks
[21:29:16] <zeeshan> hah
[21:29:17] <PetefromTn_> but I need four of them
[21:29:33] <PetefromTn_> Wish i could swing buying that northern tool thing
[21:29:42] <PetefromTn_> Looks like it would make this a piece of crumb cake
[21:29:54] <zeeshan> PetefromTn_: honestly man
[21:29:55] <PetefromTn_> there is actually one on the local craigslist for $400.00
[21:29:59] <zeeshan> when you go to shops and get quotes for that
[21:30:04] <zeeshan> doesnt it make you mad?
[21:30:12] <zeeshan> i mean if you were a clueless person
[21:30:14] <zeeshan> it might be okay
[21:30:21] <PetefromTn_> They wanted $95.00 each piece
[21:30:23] <zeeshan> but youre well versed in how things get made
[21:30:26] <PetefromTn_> plus materials
[21:30:38] <zeeshan> lol
[21:30:51] <zeeshan> i mean if it was my shop, i'd think of it like this
[21:30:54] <zeeshan> "stack 4 sheets"
[21:30:58] <zeeshan> "shear outside shape"
[21:30:59] <PetefromTn_> honestly I was more upset when one shop quoted me $35.00 over the phone after I explained what I needed
[21:31:02] <zeeshan> "bend"
[21:31:04] <zeeshan> 1hr job
[21:31:15] <zeeshan> $60 for materials
[21:31:29] <PetefromTn_> and when I showed up to pay and order it they basically tripled the price saying they did not understand what I meant
[21:31:32] <zeeshan> 120 for bending
[21:31:46] <zeeshan> wow
[21:31:46] <zeeshan> lol
[21:31:56] <renesis> they are not trying to make frens
[21:32:06] <PetefromTn_> I don't mind paying for good work but jeez man it is a simple sheetmetal tube
[21:32:24] <zeeshan> i honestly would pay upto 200bux for that work
[21:32:27] <PetefromTn_> I honestly wondered if they just priced it like they did not want to be bothered with it.
[21:32:30] <zeeshan> anything more than that, i know i am getting ripped
[21:33:03] <PetefromTn_> but I went to three different local shops and it was the same shit basically most did not want to mess with it.
[21:33:23] <zeeshan> they dont need your business
[21:33:24] <zeeshan> youre a little guy
[21:33:44] <zeeshan> i remember when i used to take aluminum piping for welding
[21:33:46] <PetefromTn_> When I told them that I already had a damn .dxf CAD drawing of it made in solidworks they laughed and said they have been there before and not had good experiences with it so they did not want to make it form the drawings.
[21:33:47] <zeeshan> 8 welds..
[21:33:54] <zeeshan> $45 per weld
[21:33:58] <zeeshan> (tig welding)
[21:34:17] <PetefromTn_> Fuckers..
[21:34:33] <zeeshan> experiences liek this
[21:34:39] <zeeshan> is the reason we end up with big ass machine tools in our garage
[21:34:39] <zeeshan> haha
[21:34:52] <PetefromTn_> Oh well I will make it myself and it will be as good as I know how to make it
[21:34:59] <PetefromTn_> should be more than fine
[21:35:15] <PetefromTn_> just wish I had a reasonable brake here to do the bends easier
[21:35:28] <PetefromTn_> going to have to do it the cave man way again ;)
[21:35:32] <zeeshan> since you're going fairly thin stuff
[21:35:35] <zeeshan> cant you use an angle iron
[21:35:41] <zeeshan> to help you bend @ each bend line
[21:35:46] <zeeshan> and just bend by hand?
[21:35:53] <PetefromTn_> yeah clamping an angle to the bench and bending from there
[21:35:57] <PetefromTn_> its thin shit
[21:36:03] <PetefromTn_> should be pretty easy
[21:36:33] <PetefromTn_> I might be able to clamp two pieces of short angle together or something
[21:36:40] <PetefromTn_> I will figure something out.
[21:37:00] <PetefromTn_> I can probably bend it by hand almost against a straight edge it is so thin.
[21:37:23] <PetefromTn_> That little mill is pretty cool.
[21:37:46] <PetefromTn_> I like how wide the Z dovetail looks and how the Z column base is triangulated outward.
[21:38:03] <PetefromTn_> It also looks belt driven from the factory
[21:38:16] <PetefromTn_> much nicer than an RF45 comes
[21:38:30] <PetefromTn_> Has Connor been in here today?
[21:38:48] <jdh> http://knoxville.craigslist.org/tls/4754065282.html
[21:38:49] <PetefromTn_> He spent the last two days in my shop working on his 0704
[21:39:11] <PetefromTn_> LOL yeah I saw that
[21:39:17] <PetefromTn_> sucks to be broke
[21:39:29] <PetefromTn_> after buying this damn air conditioning unit and all the stuff to install it
[21:39:33] <PetefromTn_> and the new to me CNC lathe
[21:39:36] <jdh> http://knoxville.craigslist.org/tls/4726206367.html
[21:39:41] <PetefromTn_> and paying for gas and trailering it here
[21:39:44] <jdh> that guy is delusional
[21:39:47] <PetefromTn_> I am basically broke as shit
[21:40:03] <PetefromTn_> yeah that is not gonna happen
[21:40:13] <PetefromTn_> maybe under a grand if it is pristine
[21:40:25] <PetefromTn_> he has been selling those for awhile now
[21:40:55] <Connor> Dang it..
[21:41:04] <Connor> I'm a little aggravated..
[21:41:17] <Connor> I got one of those HB04 pendants (wired, not wireless)
[21:41:48] <Connor> and it's not working quiet right.. The mpg isn't registering direction change consistently.
[21:41:49] <PetefromTn_> whassammatta?
[21:42:12] <PetefromTn_> oh really I was hoping it was really nice and precise
[21:42:16] <Connor> I thought maybe because I was running it in the sim
[21:42:18] <PetefromTn_> It looks like a nice unit
[21:42:43] <Connor> but, no.. i checked it out on my real time machine.. and it's still acts just as strange.
[21:42:54] <PetefromTn_> what is it doing?
[21:43:13] <Connor> It'll start counting up.. and the just switch to down... for 5-10 clicks.. and then back up..
[21:43:41] <Connor> I'm not sure if it's a driver issue, the mpg encoder, or firmware on the pendant.
[21:43:50] <PetefromTn_> you mean you turn the wheel in the same direction and it sometimes goes in the wrong direction?
[21:43:55] <Connor> yes.
[21:44:01] <PetefromTn_> damn that is not good
[21:44:06] <Connor> No. It's not.
[21:44:26] <zeeshan> ownt
[21:44:27] <PetefromTn_> does it switch between axes correctly?
[21:44:29] <zeeshan> :P
[21:44:42] <Connor> and the unit I wanted was the 16-button version.. they sent the newer one.. paid $30.00 more
[21:44:50] <Connor> thinking I was getting the 16-button version.
[21:45:05] <Connor> I think I'm going to send this one back and order another from a different vendor.
[21:45:22] <PetefromTn_> https://www.youtube.com/watch?v=HiCpUB6TpdA
[21:45:31] <Connor> Yes, it switches correctly between axis..
[21:45:52] <PetefromTn_> does it malfunction in any axis?
[21:45:59] <Connor> yes.
[21:46:14] <PetefromTn_> maybe there is something wrong with the encoder wheel wiring
[21:46:32] <Connor> I checked it.. it looked good.
[21:46:41] <Connor> I'll double check it.
[21:46:45] <PetefromTn_> you took it apart?
[21:46:53] <Connor> 6 screws. :)
[21:47:02] <PetefromTn_> damn
[21:47:12] <Connor> not the wheel, just the pendant.
[21:47:21] <PetefromTn_> you could probably easily check the wheels function with a meter
[21:47:37] <Connor> I'm not sure it's a standard MPG..
[21:47:40] <PetefromTn_> to make sure it is outputting the correct
[21:47:44] <PetefromTn_> oh really
[21:47:58] <Connor> it's Has F, B, VCC, GND
[21:48:03] <PetefromTn_> they are basically made using magnets
[21:48:15] <Connor> F instead of A ??
[21:48:38] <PetefromTn_> who knows..
[21:53:09] <PetefromTn_> What's a good filetype to take over to Staples to print this sucker?
[21:53:25] <Connor> pdf
[21:53:34] <PetefromTn_> are you sure?
[21:53:48] <Connor> what are you printing ?
[21:53:50] <Connor> and how big?
[21:53:57] <PetefromTn_> how do I make it 1-1 for them
[21:54:07] <PetefromTn_> it's about 24x28 or so inches
[21:54:18] <Connor> Oh. I have no idea.
[21:54:51] <zeeshan> PDF
[21:55:40] <PetefromTn_> if it is drawn full scale in the .dxf and I just convert to .pdf will it turn out right?
[21:57:37] <tjtr33> that benchtop, Мастер it looks like english but those are russian letters, made in the Ukraine
[21:59:32] <PetefromTn_> where do you get that macrep from?
[21:59:55] <tjtr33> add a 1" circle in a 1" square to the drawing, so you can check the scale & aspect is correct
[22:00:24] <PetefromTn_> yeah but that is AFTER they print it and I will have to probably pay for it if it is wrong
[22:00:30] <tjtr33> Мастеp http://www.madein.dp.ua/view.aspx?type=ja&lang=2&jaid=77
[22:01:26] <PetefromTn_> don't see any pictures of the machine there
[22:01:34] <tjtr33> yeah but you measure the parts you make too. and thats after you make 'em. just a way to check before you pass it onto next guy
[22:02:05] <tjtr33> PetefromTn_, its not made anymore, Andreas got a nice old machine
[22:03:31] <PetefromTn_> aah
[22:04:05] <PetefromTn_> I know that Seig was working on a 7 sized machine that had a similar base casting
[22:05:00] <PetefromTn_> http://www.amadeal.co.uk/acatalog/Syil%20X7%20CNC.jpg
[22:05:24] <tjtr33> just check smithy, they have different castings again, but some new stuff to compete with tormach
[22:05:56] <PetefromTn_> really huh
[22:06:09] <tjtr33> that Seig has a decent sized saddle
[22:07:37] <PetefromTn_> they put siemens controls on them apparently
[22:09:13] <zeeshan> PetefromTn_: yes to your question
[22:09:20] <PetefromTn_> There was a time that I would have been very interested in a machine like that
[22:09:41] <PetefromTn_> but now that I have the VMC it is no longer
[22:10:03] <PetefromTn_> besides the prices on those chinese mills is amazingly high now for whatever reason.
[22:10:19] <PetefromTn_> yes to what question?
[22:10:19] <Tom_itx> demand?
[22:10:27] <zeeshan> ] <PetefromTn_> if it is drawn full scale in the .dxf and I just convert to .pdf will it turn out right?
[22:10:36] <zeeshan> http://www.staples.com/sbd/content/copyandprint/engineering-prints.html
[22:10:36] <PetefromTn_> Ok
[22:10:37] <zeeshan> btw
[22:10:40] <zeeshan> its cheaper for you us bastards
[22:10:42] <zeeshan> 3.89
[22:10:44] <zeeshan> for a 24x36 lol
[22:11:05] <PetefromTn_> Damn that is cheap actually
[22:11:16] <PetefromTn_> makes the idea of buying a plotter seem a bit less important
[22:11:25] <zeeshan> try to order online
[22:11:28] <zeeshan> so you dont have to wait there in person
[22:11:31] <PetefromTn_> I know the consumables on the damn things are pricey
[22:11:37] <zeeshan> yea man its not worth it
[22:11:46] <zeeshan> at least not with the frequency i print drawings
[22:11:48] <zeeshan> for me
[22:12:11] <PetefromTn_> well since this is the first time I have ever had to print anything this large I guess it is even less so for me.
[22:12:28] <PetefromTn_> but yeah it will sure as hell make my life a helluva lot easier
[22:12:55] <PetefromTn_> I am right now working on the drawings adding the tabs and whatnot so I can rivet or screw it together
[22:13:08] <zeeshan> everyone has a different method but what i do for quick layout is
[22:13:16] <PetefromTn_> should have it done here soon and then I can see about sending it out for print
[22:13:19] <zeeshan> i tape it to the work piece
[22:13:24] <zeeshan> then use a center punch
[22:13:30] <zeeshan> 4 marks per line
[22:13:35] <PetefromTn_> yup
[22:13:38] <zeeshan> then i scribe using a scribe and straight edge
[22:13:41] <PetefromTn_> that is kinda what I was thinking
[22:13:56] <PetefromTn_> this drawing is pretty simple once you cut it in half
[22:14:03] <PetefromTn_> hang on
[22:14:41] <tjtr33> posterize it? and tape it together using std size paper http://manpages.ubuntu.com/manpages/lucid/man1/pdfposter.1.html
[22:14:41] <zeeshan> connor
[22:14:43] <zeeshan> hi!
[22:14:48] <PetefromTn_> http://i.imgur.com/UC7HB1W.jpg
[22:15:11] <zeeshan> haha
[22:15:15] <zeeshan> wow that does look a lot easier split up
[22:15:21] <PetefromTn_> yeah
[22:15:25] <PetefromTn_> just a couple bends
[22:15:29] <PetefromTn_> on each piece
[22:15:38] <Connor> zeeshan: Yea?
[22:15:39] <PetefromTn_> gotta add in the tabs
[22:15:51] <zeeshan> connor did you see my butchering of the mesa din rail brackets? :P
[22:16:02] <Connor> No. What did you do to them ?
[22:16:20] <zeeshan> https://www.flickr.com/photos/128539016@N05/15790564825/
[22:16:21] <zeeshan> dun dun dun
[22:16:29] <zeeshan> https://www.flickr.com/photos/128539016@N05/15605738830/in/photostream/
[22:16:29] <zeeshan> :D
[22:16:49] <zeeshan> hax
[22:17:07] <Connor> Um.. okay. Why didn't you put the mesa on din ?
[22:17:16] <zeeshan> easiet to bolt it on
[22:17:57] <Connor> That other DIN rail looks too close to the top one..
[22:18:00] <PetefromTn_> they make din mounts for the 7i77
[22:18:07] <zeeshan> Connor: it is
[22:18:08] <PetefromTn_> they are pretty nice
[22:18:13] <zeeshan> i gotta shift it down to where the fuse holders are
[22:18:18] <zeeshan> theres a line marked
[22:18:29] <zeeshan> its just too cold in the garage and im tired
[22:18:34] <zeeshan> ill turn on the heat tommo and go do it
[22:18:48] <zeeshan> i want at least the mesa and computer powered up tomorrow.
[22:19:00] <Connor> Well.. dang it.. I'm just not happy.. paid $30.00 more for the older style unit..got the newer style.. and the MPG encoder isn't working right.. it doesn't count correctly.
[22:19:32] <zeeshan> connor im honestly worried
[22:19:35] <zeeshan> cause i was going tobuy that style.
[22:19:49] <zeeshan> you think you got a defective one?
[22:20:00] <Connor> I think so.. lots of people use these..
[22:20:06] <Connor> I've not seen any reports of it doing this.
[22:20:30] <zeeshan> missing counts
[22:20:35] <zeeshan> sounds like its got a shitty wheel on it
[22:20:54] <Connor> not missing counts.. just missing changed direction.
[22:21:08] <Connor> Like I said, I don't think it's a true quadrature encoder..
[22:22:36] <zeeshan> ok bed time
[22:22:37] <zeeshan> too tired
[22:22:37] <zeeshan> cu
[22:23:15] <PetefromTn_> cya
[22:31:05] <PetefromTn_> kinda excited to have this printed tomorrow
[22:31:15] <PetefromTn_> gonna be cool to take it exactly as drawn to metal
[22:31:32] <PetefromTn_> and be able to bend it precisely where it needs to be bent
