[00:00:17] <XXCoder> HMM I see a problem
[00:00:26] <XXCoder> yours do not blend at bottom
[00:00:31] <zeeshan> what blend
[00:00:38] <Wolf_> http://i.imgur.com/Uac1MdJ.png?1
[00:00:50] <zeeshan> i win win win!!
[00:00:51] <zeeshan> :D
[00:01:10] <XXCoder> probably acceptable for whatever its used for though zeeshan lol
[00:01:13] <Wolf_> I was done when you linked it lol
[00:01:42] <Wolf_> just didn’t have a web browser open for imgur lol
[00:01:52] <XXCoder> :)
[00:03:57] <XXCoder> zeeshan: http://picpaste.com/19Qwr9M-pzwrwh1S.png
[00:04:00] <zeeshan> you win i did it wrong anyway :P
[00:04:08] <zeeshan> y es
[00:04:14] <Wolf_> lol
[00:04:37] <XXCoder> Wolf_: how did you dermine length so it blends properly?
[00:04:41] <XXCoder> I just did visual
[00:04:49] <zeeshan> XXCoder: offset a plane
[00:04:54] <zeeshan> from the centerline
[00:04:57] <zeeshan> and use pierce?
[00:05:02] <zeeshan> ( dunno if you have pierce)
[00:05:15] <XXCoder> dunno too. freecad is nice but not magical
[00:06:00] <zeeshan> http://i.imgur.com/gRZuaS8.png
[00:06:02] <zeeshan> like that
[00:06:28] <Wolf_> http://i.imgur.com/s9U9dYE.png?1
[00:06:37] <Wolf_> I did it totally different
[00:07:15] <XXCoder> interesting
[00:08:14] <zeeshan> you removed material?
[00:08:35] <Wolf_> I drew the top down and then used extrude cut to make the shape lol
[00:08:44] <zeeshan> thjat works :D
[00:08:57] <XXCoder> I did this before https://hackadaycom.files.wordpress.com/2013/12/engineeringdrawing.png
[00:09:05] * Wolf_ really has no cad training
[00:09:06] <XXCoder> took me while to figure some stuff lol
[00:09:09] <XXCoder> like that slot
[00:09:17] <zeeshan> wolf
[00:09:24] <zeeshan> here's a test to see if you've done it right
[00:09:59] <zeeshan> go to your first sketch
[00:10:03] <zeeshan> change 56 to 88
[00:10:23] <zeeshan> if it breaks
[00:10:25] <zeeshan> er
[00:10:30] <zeeshan> change 56 to 45
[00:10:39] <Wolf_> oh yeah, it will break :P
[00:10:45] <XXCoder> mine broke yeah
[00:10:49] <zeeshan> 88 will break cause its self intersecting
[00:10:53] <zeeshan> but it shouldnt break w/ 45
[00:10:59] <XXCoder> the support didnt change with base chanhge
[00:11:25] <zeeshan> try to figure out why it breaks
[00:11:28] <zeeshan> and fix the constraints
[00:11:37] <Wolf_> hmm
[00:12:39] <Wolf_> its constrained...
[00:13:10] <Wolf_> but I did fuck up on the bottom slot, should have did that as a extruded cut with a center point constraint
[00:13:51] <Wolf_> and the holes as well
[00:14:35] <Wolf_> oddly I have learn a lot by downloading product cads from mcmaster carr lol
[00:16:13] <zeeshan> hehe
[00:16:16] <zeeshan> dont stress
[00:16:24] <zeeshan> i come across this on our standard products at work
[00:16:32] <zeeshan> a 2 min change becomes a 2 hour job
[00:16:39] <zeeshan> its frustrating
[00:16:59] <zeeshan> for some reason a lot of people like to draw
[00:17:04] <zeeshan> from bottom corner
[00:17:08] <zeeshan> instead of making it symmetric
[00:17:39] <Wolf_> yeah, I have started to use the mirror function a lot
[00:17:53] <zeeshan> when i got taught in school, my instructor (really good) said:
[00:18:12] <zeeshan> symmetry, least # of steps, check if it breaks when you change a possible design change dimension
[00:18:27] <zeeshan> if you can follow those, your model will be really robust
[00:19:19] <Wolf_> it makes it easy as hell in SW with use of math functions in the parameters entry boxes too
[00:19:37] <zeeshan> yes
[00:19:42] <zeeshan> but honestly, i dont usuaully use those
[00:19:50] <zeeshan> unless im making different instances of the same thing
[00:20:04] <zeeshan> an example would be like a bolt that changes length
[00:20:05] <zeeshan> but thats it
[00:20:15] <zeeshan> 99% is constraints
[00:20:34] <zeeshan> it all depends at the end of the day what youre trying to do :P
[00:20:44] <zeeshan> we have enclosure doors at work which have different options:
[00:20:54] <Wolf_> I mean for the base parts, like 75mm wide part just shove 75/2 in the length
[00:20:58] <zeeshan> 2 lights, 3 lights, fan cutout, interlock cutout, breaker cut out
[00:21:08] <zeeshan> doors will have a combination of those
[00:21:09] <Wolf_> cause i’m lazy
[00:21:15] <zeeshan> its all formulas mostly for that
[00:21:37] <zeeshan> you could do that
[00:21:47] <zeeshan> but right click on the width line and select mid point
[00:21:59] <zeeshan> and then constrain it using vertical or horizontal constraint to the origin
[00:22:49] <Wolf_> yup
[00:23:08] <Wolf_> slowly learning that stuff as I need to change things I have drawn up lol
[00:23:32] <zeeshan> only way to learn cad :P
[00:23:47] <zeeshan> if you get time
[00:23:51] <zeeshan> and if you havent already
[00:23:57] <zeeshan> do all of the included solidworks tutorials
[00:24:07] <zeeshan> they'll really make you pro
[00:24:11] <Wolf_> found its real fun when you have a multi part assembly and you have something constrained to a odd corner then change one part...
[00:25:59] <Wolf_> was a “wtf did I mess up” moment looking at ! on every part in the stack
[00:26:10] <zeeshan> hehe
[00:27:02] <Wolf_> done right it is nice tho, take the first part and change the radius on the corners for instance and not have to mess with 3 different parts
[00:27:28] <zeeshan> its awesome when it all grows and shrinks together
[00:27:35] <zeeshan> and all the assembly parts are in harmony
[00:27:55] <Wolf_> http://i.imgur.com/Q1gnbtV.png?1 :D
[00:28:32] <zeeshan> nice
[00:28:38] <zeeshan> lots of mcmaster carr parts:d
[00:28:43] <zeeshan> that stepper mount is crazy looking
[00:28:45] <zeeshan> i like
[00:28:48] <Wolf_> yeah
[00:29:00] <Wolf_> thats for the X2
[00:29:15] <Wolf_> air spring counter weight
[00:31:43] <zeeshan> nice
[00:31:48] <Wolf_> http://i.imgur.com/PzlxMyZ.png?1 parts count looks high but the coupler is 3 parts, bearing block 2x bearings and 2 nuts, counter weight pulley 2x bearings and 2 dowels 
[00:32:37] <zeeshan> nice
[00:32:56] <Wolf_> except that the china eBay vendor sent me a sleeve of bearings with 1 5mm and 9 4mm bore lol
[00:33:28] <Jymmm> SpeedEvil: Tom_itx: Well, wood stove fire #3. You HAVE to get that that firebox HOT and it can take a while to get there. Also, remember NOT to use semi-seasoned wood... EVER! lol
[00:34:32] <Wolf_> and this is a good example to why to model first then make parts http://i.imgur.com/GgJEngr.png?1 lol
[00:38:18] <Jymmm> "For the past six years, Volkswagen has been cheating on the emissions testing for its diesel cars. The cars' computers were able to detect when they were being tested, and temporarily alter how their engines worked so they looked much cleaner than they actually were. When they weren't being tested, they belched out 40 times the pollutants. Their CEO has resigned, and the company will face an expensive recall, enormous fines and worse. "
[00:38:22] <Wolf_> … added the stepper, couplers and ball screw to that model after I made the parts and was looking at it and it didn’t look right
[00:43:29] <XXCoder> Wolf_: nice but why is it offset
[00:43:45] <Wolf_> cause measure once, cut twice
[00:44:16] <XXCoder> lol ok
[00:44:23] <Wolf_> messed up on the measurement stack on paper
[00:44:50] <XXCoder> lol https://d2t1xqejof9utc.cloudfront.net/screenshots/pics/5dddfd5e79c698f1094cb420cb4697d0/original.png
[00:45:10] <Jymmm> Hell yeah! https://www.propublica.org/article/library-support-anonymous-internet-browsing-effort-stops-after-dhs-email
[00:45:36] <Jymmm> Wolf_: And if it's still too short, cut it again until it's not!
[00:45:59] <XXCoder> yeah just cut at negative distance. no problem!
[00:48:37] <Wolf_> heh, that part doesn’t look that bad to cad out either XXCoder
[00:48:59] <XXCoder> yeah will try it when done changing part so changing stuff does not break it
[00:50:08] <zeeshan> competition ??
[00:50:09] <zeeshan> https://d2t1xqejof9utc.cloudfront.net/screenshots/pics/5dddfd5e79c698f1094cb420cb4697d0/original.png
[00:50:10] <zeeshan> ?!?
[00:50:10] <zeeshan> ;D
[00:50:19] <Wolf_> lol
[00:50:23] <zeeshan> lets do it!!!!!!1
[00:50:25] <zeeshan> then its bed time
[00:50:42] <Wolf_> naa, I need to get more parts done for the mill
[00:51:01] <zeeshan> darn :P
[00:51:04] <zeeshan> okay early bed time
[00:51:14] <Wolf_> still need to finish the Z axis and Y axis blocks
[00:51:34] <Wolf_> err Z axis ball nut mount...
[00:51:51] <Wolf_> and Y axis ball screw bearing block
[00:52:12] <Wolf_> and then hope that the sad little x1 can make the parts w/out fucking up
[00:54:21] <Wolf_> ouch found a single phase motor for that chain hoist, $500
[00:57:00] <Wolf_> fail wrong price, $599 + $40 shipping
[01:01:59] <XXCoder> dang
[01:04:41] <Wolf_> goes in something close to this http://www.ebay.com/itm/COFFING-EC-2016-3-10-Electric-Chain-Hoist-2000-lb-10-ft-/381010203568?hash=item58b5fa53b0:g:OqEAAOSwN81WDeYv
[01:14:23] <voxadam> Can anyone recommend good software for modeling the physical layout of Stewart platforms, deltas, and other parallels?
[01:20:10] <archivist> voxadam, I think you need a good solid modeller package for that
[01:21:38] <archivist> but, with linuxcnc you can model it in vismach
[01:22:14] <archivist> including the cotrol software that the others could not do
[01:25:03] <voxadam> archivist: Thanks.
[01:25:09] <archivist> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Vismach
[01:25:32] <voxadam> I just discovered a program called V-Rep. that looks interesting.
[01:26:00] <XXCoder> what the heck
[01:26:21] <XXCoder> freecad is padding something completely unrelated
[01:26:27] <XXCoder> to sketch I was working on
[02:17:32] <Deejay> moin
[02:22:27] <Wolf_> morning
[02:22:38] <XXCoder> hmm
[02:22:39] <XXCoder> https://d2t1xqejof9utc.cloudfront.net/screenshots/pics/5dddfd5e79c698f1094cb420cb4697d0/original.png
[02:22:55] <XXCoder> I cant find the though hole at top angled part diameter
[02:22:59] <XXCoder> 19 is outer diameter
[02:24:29] <Wolf_> 32mm counter sink with 9mm depth, 19mm center bore +/- 0.05mm
[02:26:10] <_PmK_> hello
[02:26:38] <XXCoder> 32 mm?
[02:26:42] <_PmK_> is someone here that has a little knowledge about hal-programming?
[02:26:44] <XXCoder> hm lemme try see that
[02:27:09] <XXCoder> 32 mm is as large as part so dont think so?
[02:27:18] <Wolf_> nope
[02:27:23] <Wolf_> 32mm radius
[02:27:29] <XXCoder> just noticed
[02:27:30] <Wolf_> part is 64mm wide
[02:27:34] <XXCoder> part is 64 mm wide not 32
[02:27:42] <Wolf_> :)
[02:30:28] <XXCoder> 32 rad I think you mean 16 rad
[02:30:29] <_PmK_> hmm. maybe im just asking.. i have connected an encoder to my mill. when i start the gui gmoccapy (or axis.. gui doesnt matter) the encoder is on value 0. is it possible to set the encoder to a value before connecting it? its connected to feed and spindle-override and its not very nice if you start the machine and forget to rotate the encoder to 100% ..
[02:30:33] <XXCoder> or 32 diameter
[02:35:44] <Wolf_> 32 rad for the nose on that plane
[02:39:10] <XXCoder> indeed
[02:39:25] <XXCoder> I did groove on "nose" and now on side
[02:39:32] <XXCoder> bottom isnt clear where groove ends
[02:39:39] <XXCoder> so I assume all way though I guess
[02:47:29] <XXCoder> Wolf_: dang that parts hard lol
[02:47:48] <XXCoder> everythings done besides that dual part on flat part
[02:47:54] <XXCoder> as well as chamfers everywhere
[03:00:35] <wicki> hi *
[03:02:52] <wicki> anybody in here, who can tell me, where to find an iso-image of "Latest releases: 2.7.1" ?
[03:03:17] <wicki> 2.7. results in segfault at startup :-(
[03:04:54] <XXCoder> hey Wolf_ that image
[03:05:04] <Wolf_> http://www.linuxcnc.org/linuxcnc-2.7-wheezy.iso ?
[03:05:18] <XXCoder> it says 51 mm height from top to surface top at back but I may be getting it wrong?
[03:06:24] <Wolf_> 90mm up the 60° part, then 51mm+32mm rad
[03:06:37] <wicki> Wolf: 2.7. does not boot here - segfault at start of xserver
[03:08:07] <wicki> 2.7.1 is anounced - but I am unable to find it
[03:08:13] <XXCoder> Wolf_: no, the other end - the dual round connectors, I'm been trying to figure the overall height including curved top
[03:08:37] <Wolf_> oh, 51mm to the centerline of the bore
[03:08:44] <XXCoder> at that end it says 51 but it doesnt show where other point is.
[03:08:49] <XXCoder> one is center of holes
[03:09:19] <XXCoder> I tried bottom of part to center bore, looks correct
[03:09:31] <Wolf_> so to teh top would be 51mm+19mm
[03:09:38] <XXCoder> indeed
[03:09:53] <Wolf_> wicki: that was the link out of the 2.7.1 docs...
[03:15:01] <XXCoder> pretty close to done lol
[03:15:28] <XXCoder> due to no curved surface sketch support i gonna cheat for tiny holes on top.
[03:17:08] <wicki> wolf: a little bit strange, isn't it? link to 2.7.1 results in an 2.7. image ?
[03:17:48] <Wolf_> .1 part of the update is for teh cnc soft no the os
[03:32:35] <wicki> now I have tried 3 different PCs: linuxcnc-2.7-wheezy.iso does not boot - segfault at start of X-server. only on an virtual machine the image ist running.
[03:41:21] <XXCoder> dammit
[03:41:25] <XXCoder> I changed one design
[03:41:29] <XXCoder> rest isnt updating to it
[04:38:09] <archivist_herron> wicki, the iso follows later, just run your normal system update and linuxcnc should be updated too
[04:49:13] <wicki> archivist: oki - I'm trying to install 2.7 on a virtual machine now. on real hardware, the x-server is crashing.
[05:11:43] <XXCoder> hmm forgot who we was chatting about on eink stuff in here?
[05:11:50] <XXCoder> because heres interesting stuff https://youtu.be/02O9sXL1Rr4
[05:12:41] <fenn> me
[05:15:54] <XXCoder> cool
[05:15:56] <fenn> anyone could make these demo products if they would actually sell the displays
[05:16:45] <fenn> the technology has been around forever, it's been limited mostly by bad licensing strategies
[05:24:55] <fenn> the screen update is actually a lot faster than their demo
[05:25:11] <XXCoder> some of screens is quite fast
[05:25:21] <XXCoder> almost enough to play movie
[05:25:28] <XXCoder> grayscale one but yeah
[05:25:33] <fenn> yes i have seen people playing sonic the hedgehog at 15 fps
[05:25:45] <fenn> uses lots of battery if you do that though
[05:25:51] <XXCoder> I bet
[05:27:06] <fenn> i want to do wallpaper that you "paint" on images with an electric "digital paint" roller
[05:27:23] <Wolf_> one thats used in the pebble smartwatch refreshes fast
[05:27:34] <XXCoder> yeah
[05:27:56] <XXCoder> very fast for not using norefresh type
[05:28:16] <fenn> i might have to make my own e-ink though, the company has had 20 years to sell it and it's still impossible to buy
[05:28:31] <XXCoder> how is it made anyway
[05:29:16] <fenn> microfluidic encapsulation of beads in a droplet of liquid and then again in a hardening polymer i think
[05:30:37] <fenn> if three channels join, the two outer channels become the outer layer
[05:32:00] <fenn> like this http://youtu.be/0sde48D2eFs
[05:33:35] <XXCoder> hmm
[05:34:02] <fenn> the bead is coated on one side with a positively charged ink, and it's free to spin inside the fluid so it aligns with an externally applied electric field
[05:34:33] <XXCoder> ahh
[05:34:40] <XXCoder> but how does it do 256 shades of gray
[05:45:26] <XXCoder> http://36.media.tumblr.com/a0187a09d4ae915852a8e313f0c680fd/tumblr_ntutkw9r2B1rrqskho1_r1_1280.jpg darn I need to mow my pool
[05:45:37] <fenn> this makes it look like there are a lot of beads per capsule, and gray scales are caused by some of the black beads being near the top https://en.wikipedia.org/wiki/File:Electronic_paper_(Side_view_of_Electrophoretic_display).PNG
[05:45:41] <XXCoder> http://terriblerealestateagentphotos.com/
[05:46:00] <XXCoder> interesting
[05:46:14] <XXCoder> and wow it has rare antilight ;) (black ray)
[05:47:01] <fenn> oil stain
[06:18:17] <XXCoder> fenn: its possible it is dead end tech, with just advert signs. because there is new tech that works in both sunlit and inside
[06:18:27] <XXCoder> it even has larger range colors than basic RGB
[06:18:43] <XXCoder> newbie tech still though, lets see if it gets to market.
[06:20:32] <SpeedEvil> fenn: It's depressing.
[06:21:07] <SpeedEvil> fenn: It would be so awesome to just be able to take a PCB, laminate on some e-ink film, some transparent conductive plastic, and yo've got a segmented display of arbitrary shape
[06:21:38] <XXCoder> SpeedEvil: Sony once showcased watch that shows face in ink... and entire band too
[06:21:48] <XXCoder> nothing come of it so far
[06:22:37] <fenn> xxcoder are you talking about the qualcomm/mirasol technology?
[06:23:38] <XXCoder> looks like yes
[06:23:48] <fenn> well i dunno what the hell their problem is
[06:24:11] <fenn> spend $2B and nothing to show for it but a single ebook reader
[06:24:59] <SpeedEvil> Mirasol I don't think can work
[06:25:10] <SpeedEvil> It's a fundamentally flawed technology - from what I remember
[06:25:22] <SpeedEvil> It works in principle OK if tehre is a single bright point-source of light.
[06:25:26] <SpeedEvil> Otherwise, not.
[06:25:30] <fenn> http://teleread.com/chris-meadows/mirasol-pixel-qi-where-are-they-now/
[06:25:32] <XXCoder> interesting
[06:25:38] <SpeedEvil> One of those things that works well for demos.
[06:26:42] <fenn> when i use an e-ink display i'm either 1) outside, or 2) sitting in my reading chair with an overhead lamp
[06:27:00] <fenn> so i don't see the problem
[06:27:09] <SpeedEvil> I live in scotland.
[06:31:45] <XXCoder> interesting http://www.amazon.com/Pixel-Qi-Model-3Qi-01-backlight/dp/B00IYWBODI/ref=sr_1_1?s=pc&ie=UTF8&qid=1445252850&sr=1-1&keywords=Pixel+Qi
[06:32:30] <XXCoder> https://www.adafruit.com/products/1303
[06:32:35] <XXCoder> kit with raspberry
[06:32:40] <XXCoder> or maybe not raspberry
[06:33:01] <Topy44> quick engineering question, i am designing a changeable-head-system for a 3d printer
[06:33:16] <fenn> kinematic mount!
[06:33:18] <Topy44> i need to design a mechanism to quickly and securely fasten the heads to the x carriage
[06:33:25] * fenn turns on the broken record
[06:33:47] <Topy44> traditional cartesian printer
[06:34:27] <Topy44> the mount should be lasercutable or at least 3d printable
[06:34:34] <malcom2073_> Topy44: Thingiverse has stuff for that I'm sure
[06:34:38] <SpeedEvil> Use one head, and exchange the nozzles
[06:34:40] <Topy44> nothing good that i could find
[06:34:48] <malcom2073_> I'd use a camlock, similar to how camera mounts work though, not sure how laser cuttable that is
[06:34:48] <Topy44> SpeedEvil: no i have mutliple hotends and extruders
[06:34:55] <fenn> Topy44: http://www.g2-engineering.com/technology-kinematics
[06:34:55] <Topy44> for 1.75mm and 3mm and so on
[06:35:07] <Topy44> malcom2073_: you mean like a dovetail thing?
[06:35:14] <malcom2073_> Topy44: Yes
[06:35:26] <Topy44> fenn: i do not see how this relates to my question
[06:35:35] <fenn> the goal is to have repeatable positioning, yes?
[06:35:38] <Topy44> malcom2073_: thats what i thought too, but yeah, not really laser-cuttable
[06:35:39] <Topy44> well
[06:35:40] <SpeedEvil> fenn: then your fu is weak.
[06:35:49] <Topy44> Z positioning has to be repeatable
[06:35:55] <Topy44> XY is not critical
[06:36:02] <Topy44> (1mm or so is good enough)
[06:36:22] <Topy44> Z is important because of the Z end stop, so it should be precise to about .05mm
[06:36:32] <fenn> the page is exactly what i wanted, just read it
[06:37:28] <malcom2073_> Topy44: Your printer's Z likely isn't accurate to 0.05 fwiw, especially if it's unsupported smooth rod :P
[06:37:42] <malcom2073_> But yeah, dovetail and camlock
[06:37:50] <malcom2073_> 3d printable though
[06:37:53] <Topy44> i'd argue it is actually
[06:38:28] <SpeedEvil> Topy44: have you computed the beam sag?
[06:38:33] <malcom2073_> Topy44: Get a dial indicator, then press one finger gently on the rail, just rest it on it. a 300mm span of 10mm rod flexes significantly more than 0.05mm if you lay a pen on it.
[06:38:35] <Topy44> Z uses a ballscrew plus smooth rod for positioning
[06:38:51] <Topy44> malcom2073_: ofc
[06:39:06] <Topy44> but that doesn't matter
[06:39:12] <fenn> i've seen 20 micron layer height prints, looked ok
[06:39:19] <Topy44> as the z end stop is part of the x carriage
[06:39:31] <SpeedEvil> fenn: that means you have 20 micron repeatability at a given point.
[06:39:38] <fenn> yes
[06:39:47] <SpeedEvil> fenn: it does not mean you have 20 micron flatness across the bed
[06:39:52] <fenn> certainly not
[06:39:56] <malcom2073_> Topy44: My point is: It'sgoing to be as accurate as anything you solid mount down (dovetail/camlock for instance) :)
[06:39:58] <Topy44> the important thing is that the position of the hotend to the end stop is repeatable
[06:40:26] <SpeedEvil> this is somewhat more important because if you're swapping hotends, the weights may vary
[06:40:28] <Topy44> yes, dovetail/camlock does sound good, however its not laser cutable
[06:40:43] <malcom2073_> True, ask in #reprap, they're better at coming up with hacks instead of solutions though
[06:40:44] <Topy44> SpeedEvil: again, the endstop sensor is _on the carriage_
[06:40:52] <Topy44> so any bend in the x axis will be compensated
[06:41:31] <Topy44> malcom2073_: the very reason i am asking here and not in #reprap :)
[06:42:23] <SpeedEvil> Steel ball bearings registering in holes, drawn up by a bolt may be quite adequate
[06:42:24] <malcom2073_> Limiting yourself to laser cutting is going to make it difficult, since you can't do angle cuts with lasers. You could do some sort of bolt-down thing with captive nuts glued in, but it'd be harder to swap
[06:42:38] <fenn> Topy44: kinematic triple V mounts are usually made by embedding dowel pins into something; in your case the "something" is a laser cut sheet with rectangular holes for the dowel pins
[06:42:48] <Topy44> actually that could work, yes
[06:42:52] <fenn> the dowel pins provide the v-groove that the ball bearings sit in
[06:43:02] <malcom2073_> Dowel pins are a good idea for repeatable positioning
[06:43:10] <malcom2073_> Dowels to align, bolts to secure
[06:43:16] <fenn> malcolm that's not what i'm saying at all
[06:43:28] <malcom2073_> fenn: I didn't say it was
[06:43:43] <malcom2073_> You're using them sideways
[06:43:51] <fenn> it's frustrating when everyone is trying their hardest to ignore what i'm saying
[06:44:01] <Topy44> i'm not :(
[06:44:18] <Topy44> trying to understand your suggestion
[06:45:00] <Topy44> hm, i guess if i make a nice jig i could laser cut dovetails
[06:45:14] <Topy44> or the dowel pin setup
[06:45:15] <Topy44> hrm
[06:45:21] <Topy44> yeah this gives me some ideas
[06:45:25] <malcom2073_> I think fenn is suggesting instead of dovetails, use three dowels, two to form the "v", and one to go in it
[06:45:26] <malcom2073_> ?
[06:46:54] <fenn> this is what you're trying to build using laser cut parts instead of anodized aluminum blocks: https://www.thorlabs.com/images/TabImages/Breadboard_Component_Seat_A1-540.jpg
[06:47:35] <fenn> those discs are neodymium magnets but you could instead use a cam in the center to provide holding force
[06:53:57] <Jymmm> Eh, alignment pins and wingnuts.
[06:55:47] <Jymmm> Repeatable positioning and quick to swap out.
[07:03:50] <Tom_itx> Jymmm, the pioneers knew... the first 10 min after building a fire cleared out all the spiders and bugs. if anything was still living after that it was warmed by the fire
[07:04:18] <fenn> whatever doesn't kill you makes you stranger
[07:04:28] <XXCoder> lol
[07:04:32] <Jymmm> Tom_itx: First 10m was the smoke filling the room? lol
[07:04:40] <Tom_itx> uh huh
[07:04:46] <Jymmm> that's funny =)
[07:05:04] <fenn> the trouble with precision mounting of things with heaters in them is that they expand in use unpredictably with temperature changes
[07:05:10] <Tom_itx> if anything remained, they used hedgeballs to kill the rest
[07:05:45] <Jymmm> if anything was left, I wouldn't be sticking around to find out wth it was!
[07:07:01] <Jymmm> It's kinda like the horror films... When the demonic house says "G E T O U T", you don't stick around, you GTFO
[07:08:36] <fenn> jymmm this one's for you: https://www.youtube.com/watch?v=d6E6Pu3a5qM
[07:11:16] <Jymmm> fenn: Hmmm, I don't get the refernce
[07:11:39] <Jymmm> still on first cup too =)
[07:12:24] <fenn> fire is the catalyst!!!
[07:12:32] <Tom_itx> use napalm to start fires?
[07:13:09] <Jymmm> Well, if I just wanted fire, I have safety fuse. 100% waterproof too =)
[07:13:32] <Jymmm> as in "burns under water"
[07:13:48] <XXCoder> just make sure your car wont suddenly stall and hard to start at plot convient time
[07:14:58] <Jymmm> XXCoder: lol
[07:15:30] <Jymmm> XXCoder: That's what the hoverboard is for
[07:15:36] <XXCoder> lol yep
[07:15:59] <XXCoder> I bet there would be hoverbicycle
[07:16:07] <XXCoder> works like bicycle but real smooth ride.
[07:16:20] <Jymmm> XXCoder: What, you think you're ET?
[07:16:31] * XXCoder call home
[07:17:27] <XXCoder> quick, design a CAD out of this! http://www.lhup.edu/~dsimanek/3d/ring-gear.gif
[07:17:50] <Jymmm> done!
[07:17:55] <fenn> it's not even animated
[07:19:42] <XXCoder> Jymmm: well?
[07:20:02] <Tom_itx> XXCoder, now machine it
[07:20:14] <XXCoder> not without cad model lol
[07:20:15] <Jymmm> XXCoder: running the job now, dont get your panties in a bunch!
[07:20:38] <XXCoder> lol
[07:21:07] <XXCoder> sigh dunno why this part 2 edge refuse to be chanfered without part disappearing
[07:21:16] <XXCoder> I literally chamfered all other edges.
[07:21:45] <Jymmm> XXCoder: Ok, done... https://www.youtube.com/watch?v=0v2xnl6LwJE
[07:22:06] <XXCoder> lol saw that before
[07:22:16] <XXCoder> wrong impossible object ;0
[07:22:37] <Jymmm> XXCoder: Hey, you cam your way, I'll cam mine biotch!
[07:22:44] <XXCoder> lol
[07:24:33] <fenn> http://boingboing.net/2011/04/06/mobius-gear-a-one-si.html
[07:25:11] <XXCoder> nice
[07:25:59] <XXCoder> any of you expert with freecad?
[07:27:10] <fenn> i've used opencascade libraries enough to distrust freecad
[07:27:20] <Jymmm> https://www.youtube.com/watch?v=W07ADwmuj8A
[07:28:17] <XXCoder> it says failed to create fillet (but must be executed)
[07:28:20] <fenn> seriously jymmm? this is in literally every puzzle book ever
[07:29:09] <Jymmm> fenn: I'm just not nerdy enough to have every own/read a puzzle book I guess =)
[07:29:17] <Jymmm> ever*
[07:30:02] <fenn> a farmer wants to cross a river with a fox, a chicken, and a bag of grain...
[07:30:22] <Jymmm> 42
[07:30:27] <Jymmm> The answer is 42
[07:30:42] <fenn> you are going 80 miles per hour. how long does it take to go 80 miles?
[07:31:11] <XXCoder> 5 hours. police takes a long time to write ticket.
[07:31:27] <fenn> is that your final answer?
[07:31:31] <XXCoder> yep
[07:32:45] <Tom_itx> uphill or down?
[07:33:29] <Jymmm> yes
[07:33:39] <Tom_itx> what would really matter is if you were going east or west
[07:37:00] <XXCoder> is temp -40F or -40C?
[07:37:33] <Jymmm> -40k
[07:44:00] <Jymmm> LOL this looks cool... https://www.youtube.com/watch?feature=player_detailpage&v=o3bMSNWoeFw#t=542
[07:44:58] <XXCoder> lol fail
[07:53:44] <_methods> stuck in human feces
[07:54:05] <XXCoder> trying to surf in it
[08:35:40] <Sync> hmm zeeshan I've been looking at 321 stainless today, it might be ok but I'm having trouble to source it in thin pipes
[08:44:43] <Wolf_> http://www.walmart.com/ip/NEMA-24-2-Phase-Robot-Lathe-CNC-Stepper-Motor-76mm-4A-311oz.in-w-Driver/47002373 and go :P
[09:44:16] <enleth> do you have any experience with in-place taper reconditioning?
[09:45:07] <_methods> how bad is the taper?
[09:45:37] <enleth> not totally fucked but looks bad
[09:45:48] <_methods> you have a spindle wiper?
[09:46:05] <_methods> are tools hangin up when it does a tool change?
[09:46:15] <enleth> as in, the angle is OK, no bellmouthing, but lots of scratches and pitting
[09:46:20] <_methods> or is it so bad it can't complete?
[09:46:49] <_methods> well i wouldn't do anything crazy unless it was actually interfering with tool changes
[09:47:00] <enleth> it's too loose I think, due to uneven surface
[09:47:01] <_methods> and get a spindle wiper
[09:47:06] <_methods> oh
[09:47:18] <_methods> cat 40?
[09:47:26] <enleth> and I guess there are high spots in there
[09:47:36] <enleth> QC30
[09:47:47] <fenn> use a rounded abrasive stick to take off the high spots?
[09:48:04] <_methods> i would get a spindle cleaner with teh right taper
[09:48:23] <fenn> you can check the fit with engineer's blue
[09:48:40] <fenn> it will tell you where you need to remove material
[09:49:42] <ssi> yeah it can be done but it'll be a slow iterative process
[09:49:53] <enleth> so far I had some dirty oil act as accidental engineer's blue and it looks bad
[09:50:10] <fenn> there's also the nuking from orbit option: CNC boring the taper with a CBN insert
[09:50:34] <ssi> or mount a die grinder in the vise and grind it
[09:51:19] <_methods> well bluing it will definitely highlight the high spots
[09:51:35] <enleth> I think what the commercial reconditioningservice does is mounting a tapered die grinder
[09:52:15] <_methods> you could do the same thing with fine sand paper on at cat30 wiper tool
[09:52:47] <enleth> with so much time invested into this mill, having someone do it for once sounds appealing
[09:53:14] <_methods> that is the high success rate path lol
[09:53:36] <ssi> I wonder what it'd cost
[09:53:45] <enleth> it's not a very interesting problem, it sounds like a tedious task and probably is easy to screw up and end up worse off
[09:53:58] <ssi> yep
[09:54:35] <ssi> I did my first aluminum pour on saturday!
[09:54:53] <ssi> https://scontent-atl3-1.xx.fbcdn.net/hphotos-xpa1/v/t1.0-9/12118888_10100797165231992_5455035055934594954_n.jpg?oh=12c809ada80c0a9dd47da601929c4e26&oe=56C2D231
[09:55:02] <enleth> it was fun to take this machine apart, put it together and fix mechanical and electrical problems, this isn't
[09:56:05] <fenn> ssi make blocks and cylinders so at least you can use them
[09:56:06] <enleth> ssi: nice. gas or electric?
[09:56:09] <ssi> propane
[09:56:29] <_methods> nice pour
[09:56:30] <Wolf_> some lapping compound, a drill and a toilet brush to fix that spindle? :D
[09:56:50] <Sync> if you trust the control you can just hard turn the taper enleth
[09:56:52] <ssi> I then spent a bunch of time making a flask, including turning alignment pins for it
[09:56:58] <Sync> and sneak up on it
[09:56:58] <ssi> making a screen, screening sand, mixing greensand
[09:57:06] <ssi> then I tried to make a mold, and learned a couple things:
[09:57:12] <ssi> 1) my sand is too dry
[09:57:38] <ssi> 2) 50lb sand isn't enough to fill a 12x10x11" flask
[09:57:55] <fenn> switch to lost foam, your back will thank you
[09:58:01] <renesis> damn, rly?
[09:58:09] <ssi> 3) I intended to route a "key" into the interior of the flask before assembling it, but I forgot. Without it, the entire mold dumps out the bottom when I try to pick it up :D
[09:58:20] <ssi> so I glued some 1/4" strips inside in place of the groove
[09:58:21] <renesis> i dont think lost foam eliminates the sand?
[09:58:29] <ssi> lose a little interior volume that way but it'll work
[09:58:48] <fenn> don't worry, the sand will fall out of the cope even with the key
[09:58:59] <Wolf_> lost foam/pla/wax means you don’t need to lift half the flask
[09:59:06] <Sync> anybody here with a yaskawa sigma 2 drive and an absolute encoder?
[09:59:14] <renesis> oooh, huh
[09:59:33] <renesis> but then its all up in your part!
[09:59:53] <ssi> I'll probably experiment with lost $x, but I want to do split pattern casting some too
[10:02:52] <ssi> also I probably made my first flask excessively large
[10:02:57] <ssi> I might oughta make another smaller one
[10:05:39] <_methods> go big or go home lol
[10:05:56] <ssi> I really really don't want to mix another batch of sand
[10:05:58] <ssi> that was an asshole
[10:06:25] <_methods> yeah casting stuff would be fun if it wasn't for all the fire and sand stuff
[10:06:35] <ssi> heheh
[10:07:45] <Sync> ssi: just buy premade casting sand?
[10:08:00] <ssi> if I could get it locally I would
[10:08:25] <ssi> or on amazon :P
[10:08:28] <ssi> plus it's quite expensive
[10:09:00] <_methods> says the guy with a pile of airplanes
[10:09:16] <ssi> yeah, I have four airplanes! in what universe would someone like me have MONEY?! :)
[10:09:24] <_methods> hahah
[10:09:25] <_methods> true
[10:09:50] <ssi> but seriously, 50lb of petrobond is like $100
[10:09:59] <ssi> and we've already established that 50lb doesn't fill my flask :(
[10:10:03] <_methods> dayum
[10:10:41] <ssi> mixing the sand isn't actually that awful, I used a heavy duty concrete paddle in a drill
[10:10:50] <ssi> what sucks about it is having to add the water slowly with a spray bottle and mix it in
[10:10:53] <ssi> takes forevers
[10:11:18] <Wolf_> cheap concrete mixer
[10:11:32] <Wolf_> via cragslist
[10:11:35] <ssi> at this point a cheap mixer would have paid for itself
[10:11:41] <ssi> between mixing refractory and sand
[10:12:22] <Wolf_> I got a harbor freight one, its had 3 pallets of concrete through it already lol
[10:12:32] <ssi> the smallest hf one is $149 I think
[10:12:34] <ssi> really not horrible
[10:13:03] <ssi> fenn: is fennetic.net you?
[10:14:41] <fenn> this seems like something i should be cagey about answering
[10:14:48] <ssi> lol
[10:15:06] <ssi> a page on that site came up when searching for petrobond prices, and there's quite a nice writeup about oil bonded sands
[10:15:21] <ssi> and you seem to have some experience with casting
[10:15:28] <ssi> it's a pretty easy logical jump to assume it might be yours :)
[10:15:36] <fenn> i've never done oil bonded sand
[10:15:47] <ssi> well then
[10:15:52] <ssi> someone's out there usurping your identity
[10:16:28] <Wolf_> yay my possibly busted ass probe shipped
[10:16:42] <fenn> ok furrywolf you can take off the disguise now
[10:17:25] <ssi> also it's probably fruitless to be cagey about your online endeavors when at some point you reference your irc handle and network, and also publish data on your sleep habits :D
[10:17:54] <fenn> i can neither confirm nor deny
[10:18:03] <Wolf_> lol
[10:18:09] <ssi> oh snap, Glomar'd
[10:18:37] <Wolf_> so anyone bother to mess with the path p stuff yet?
[10:19:06] <enleth> ssi: try a plaster mould maybe?
[10:19:15] <ssi> enleth: I'll make the sand work, no biggie
[10:19:25] <fenn> plaster has a nasty habit of exploding
[10:19:25] <_methods> zlog
[10:19:41] <ssi> I just need to fine tune my _methods
[10:19:44] <enleth> ssi: plaster is reusable-ish
[10:19:51] <_methods> heheh
[10:19:56] <enleth> if you are careful and lucky
[10:20:46] <skunkworks> https://groups.yahoo.com/neo/groups/mach1mach2cnc/conversations/messages/149207
[10:21:07] <skunkworks> but a lot of people have already paid for it..
[10:24:51] <_methods> oops
[10:35:09] <ssi> lol quote on this site is gold: "Start by building some casting flask that will hold the sand. Casting is far to macho to just call them sand boxes."
[10:36:18] <SpeedEvil> https://www.youtube.com/watch?v=s7DqwRKqyMk
[10:39:16] <ssi> quality entertainment
[10:41:08] <SpeedEvil> ssi: What're you trying to cast?
[10:41:27] <ssi> I don't have a single goal in mind
[10:41:42] <SpeedEvil> :)
[10:41:43] <ssi> there are a few little things I'd like to be able to make, a couple particular airplane parts
[10:41:50] <ssi> but it's just a nice technology to add to the shop
[10:42:14] <SpeedEvil> yeah.
[10:42:32] <SpeedEvil> I've wondered about vacuum casting
[10:42:48] <ssi> man if I had a vacuum furnace I would totally cast some titanium keys
[10:42:57] <Wolf_> cast up one of these http://www.conleyprecision.com/609.htm
[10:43:13] <ssi> Wolf_: totes 'dorbz
[10:43:15] <SpeedEvil> ssi: I've been pondering a large vacuum chamber for a bit.
[10:44:26] <ssi> what fo?
[10:44:47] <anomynous> welding without gas? ;D
[10:45:02] <SpeedEvil> Playing with stuff.
[10:45:26] <SpeedEvil> e-beam welding/3d printing/casting/melting
[10:45:34] <ssi> e-beam welding!
[10:46:03] <ssi> http://chestofbooks.com/crafts/popular-mechanics/The-Boy-Mechanic-700-Things-for-Boys-to-Do/index.html#.ViUKiLQrr8s
[10:50:10] <ssi> hahah
[10:50:10] <ssi> The first thing to make is a molding bench, as shown in Fig. 1. It is possible to make molds without a bench, but it is a mistake to try to do this, as the sand is sure to get on the floor, whence it is soon tracked into the house

[10:56:40] <fenn> e-beam welding for the boy mechanic
[10:56:44] <ssi> :D
[10:56:51] <fenn> start by disassembling your father's television set...
[10:57:15] <ssi> I watched an awful lot of youtube videos about making homemade Xray tubes
[11:01:19] <archivist> who needs to make when 1960s TVs had them in the line out stage
[11:04:36] <CaptHindsight> I've seen lost of cheap dental xray sources on fleabay
[11:04:43] <CaptHindsight> some will sell to anyone
[11:15:49] <DaViruz> a friend of mine made a xray machine using a rectifier tube for an xray-tube, it produced pretty decent images
[11:20:06] <DaViruz> https://www.flickr.com/photos/hochspannung/7214361060/
[11:20:26] <DaViruz> the black-white ones are the rectifier tube, the green ones are with a real xray tube
[12:16:41] <ssi> hm I think I got the wrong tracking number for my newegg motors
[12:16:48] <ssi> it says it's out for delivery in rockledge florida :P
[12:50:04] <skunkworks> https://groups.yahoo.com/neo/groups/mach1mach2cnc/conversations/messages/149214
[12:51:35] <skunkworks> Do I post and say - actaully the pci card is $89 - pcie is $109
[12:53:55] <archivist> no idea what the smoothstepper and others cost in comparison
[12:55:19] <archivist> I should have shown him my lathe on steppers screw cutting when he was here :)
[12:55:39] <skunkworks> you should have..
[12:55:52] <skunkworks> he mentiones the hobber every so often...
[12:56:46] <archivist> he emailed me a couple of weeks ago to ask about a few things
[12:58:22] <skunkworks> ethernet smooth stepper is a buffered motion controller for mach3-4. it is around 180 and emulates 3 printer ports. (high speed stepping)
[12:58:38] <skunkworks> although I think it still only does index threading
[13:02:14] <archivist> I must upgrade the hobbing setup to include the differential comp one day
[13:04:04] <archivist> then helicals can be done more correctly
[13:05:26] * Loetmichel did screw cutting on the C axis in the gantry router lately ;)
[13:06:38] <Loetmichel> https://www.youtube.com/watch?v=yDcCyF_gVoY <- was to cheap to buy an M16*2 thread cutter for 2 aluminium screws ;)
[14:03:43] <SpeedEvil> Loetmichel: It's aluminium.
[14:03:50] <SpeedEvil> m16 nut, impact driver
[14:04:17] <Loetmichel> SpeedEvil: have no impact driver
[14:04:24] <Loetmichel> and it was 7075
[14:04:34] <Loetmichel> i doubt that would go well with "forming"
[14:04:46] <SpeedEvil> :)
[14:09:15] <lair82> Afternoon Gentlemen, I am trying to setup sbackup on my mill to backup to my pc in my office, to keep the nc files on the machine relibly copied to another loaction, and am having issues completing the setup for the ssh connection. I set this up on my three turning centers, by just clicking on the generic stuff in the ssh box, filling it in to direct to my pc, and it just works. This version is bringing up this smaller box that needs

[14:12:16] <LatheBuilder2> pcw, 7i77 encoder inputs do not have internal pulldowns, correct? (when jumpered for single ended operation)
[15:03:24] <PetefromTn_> afternoon folks
[15:06:13] <XXCoder> hey'
[15:06:56] <PetefromTn_> hey coder
[15:12:25] <Wolf_> morning
[15:12:42] <XXCoder> hey
[15:13:00] <PetefromTn_> morning wolf
[15:15:16] <Wolf_> this is a first for me, 2 eBay orders screwed up in the past few days
[15:16:45] <PetefromTn_> you screwed up delivery orders or you had sellers screw up your order ;)
[15:17:06] <Wolf_> stuff I needed for the mill project
[15:22:19] <PetefromTn_> well that sux
[15:22:40] <PetefromTn_> did you not receive it or not received the correct items?
[15:23:20] <MrSunshine> anyone here repacked chinese ballnuts ?
[15:23:28] <PetefromTn_> I have
[15:23:31] <MrSunshine> those who do not have a unscrewable ball return
[15:23:34] <Wolf_> not yet…
[15:23:59] <Wolf_> have the ones with 2 plastic caps?
[15:24:00] <PetefromTn_> mine had the little ball return tube
[15:24:04] <PetefromTn_> unscrewable
[15:24:06] <MrSunshine> Wolf_: yeah
[15:24:23] <Wolf_> same here, I haven’t poked them yet either
[15:24:24] <MrSunshine> dont know how there are in there and i think i need to clean out my nuts from mdf dust
[15:24:31] <MrSunshine> tho new nuts are not expensive
[15:25:12] <MrSunshine> what i find on youtube is to repack them then insert the ballscrew
[15:25:14] <PetefromTn_> you can make little brushes for the nuts/screw interface or I have seen people just put a bunch of hot glue on there to sort of make a seal
[15:25:56] <MrSunshine> there is a nylon thingie there that scrapes up stuff some but maybe not all
[15:26:07] <Wolf_> if it was me, I would order 1 spare nut then attempt to repack them with better balls
[15:26:47] <MrSunshine> started to get some strange sounds on both X and Y axis that i ahvent had before and when moving Y axis i can hear a reoccuring sound over and over
[15:27:09] <Wolf_> clicking?
[15:27:35] <Wolf_> may want to check the preload AC bearings as well
[15:27:45] <MrSunshine> AC ?
[15:27:55] <Wolf_> angular contact
[15:28:14] <MrSunshine> not realy clicking sound
[15:28:41] <Wolf_> oh wait, thats my POS mill that makes the clicking ;D
[15:28:58] <MrSunshine> well i can unscrew the ballnuts from the machine and feel them also
[15:29:12] <MrSunshine> but i know something is moving, got 0.2mm about if i push the axis in play
[15:29:27] <MrSunshine> but i have to push hard
[15:29:49] <Wolf_> there is a end block with 2 bearings in it right?
[15:29:56] <MrSunshine> and it stays at +0.2mm .. then i tugg it and it goes back to 0 and stays there, i think its the nut holding the ballscrew in the fixed block
[15:30:06] <MrSunshine> Wolf_: yes, fixed end
[15:30:38] <Wolf_> http://i.imgur.com/GnZe96O.jpg but thats from a different design lol
[15:31:12] <Contract_Pilot> Hey all.
[15:31:15] <MrSunshine> ah you are the torque guy :P
[15:31:37] <Wolf_> yeah, 425oz in steppers on a X1 micro mill lol
[15:32:13] <MrSunshine> oz ...
[15:32:17] <MrSunshine> if i could slap you i would
[15:32:40] <Wolf_> I’m going to put some ~150oz ones on there soon
[15:32:45] <Wolf_> if they ever arrive
[15:33:07] <MrSunshine> high torque is a good thing imo .. less chance stuff stalls =)
[15:33:32] <andypugh> MrSunshine: I have done it with the plastic insert nuts
[15:33:46] <Wolf_> yeah I plowed a chunk of alum right though a 7/16” end mill, didn’t even slow down
[15:33:57] <MrSunshine> andypugh: any tips ? =)
[15:34:02] <Wolf_> broke the end mill in half lol
[15:34:07] <andypugh> Don’t be too afraid
[15:35:43] <andypugh> MrSunshine: Terribe photo, but: https://picasaweb.google.com/lh/photo/4UHtgZQZ8-sR_AE8DnpE2NMTjNZETYmyPJy0liipFm0?feat=directlink
[15:36:42] <Contract_Pilot> Anyone get their new egg order?
[15:36:57] <andypugh> If you look you can see that the little plastic cap has moved out and left a shoulder of steel for the balls to wedge against. I filled the plug-pockets with epoxy putty on the replacement nut (The nut fits in a bore) to hopefully prevent the same thing happening again.
[15:37:07] <Wolf_> man that Tasharina Corp is a odd bunch, they listed http://www.walmart.com/ip/47002373 again at $11 this morning, like 20 of them
[15:37:23] <Contract_Pilot> Mine is showing out for delivery in Houston TX i am in vancover, WA
[15:37:38] <Wolf_> lol
[15:37:43] <Wolf_> thats not good
[15:37:43] <XXCoder> lol
[15:37:44] * SpeedEvil is awaiting cancellation confirmation for 36 quadcopters at $1.99
[15:37:48] <XXCoder> also, vancouver sucks :P
[15:37:53] <XXCoder> lived there for long time
[15:38:03] <Wolf_> I got one of my new egg motors
[15:38:17] <andypugh> It is probably worth making a plug of ball screw root diameter with a tapered lead-in (and no centre hole to lose a ball in, as illustrated in my photo) but you can just put the balls in as you screw the screw in.
[15:38:20] <XXCoder> SpeedEvil: tiny ones? lol
[15:38:34] <Contract_Pilot> Wonder if they just got the tracking #'s mixed up.
[15:38:45] <SpeedEvil> XXCoder: yes. http://www.banggood.com/Eachine-H8-Mini-Headless-Mode-2_4G-4CH-6-Axis-RC-Quadcopter-RTF-p-975808.html
[15:38:53] <Contract_Pilot> My other one is at destination Albany NY
[15:39:34] <XXCoder> 14 bucks each now, guess they fixed it lol
[15:39:58] <SpeedEvil> yeah
[15:41:24] <Wolf_> 1 of 2 https://tools.usps.com/go/TrackConfirmAction.action?tLabels=LS152569395CN which I thought was 6 motors but the one oddball showed up alone in the mail today
[15:42:15] <Contract_Pilot> http://track.trackingmore.com/lesotho-post/en-LS152570371CN,LS152571258CN.html
[15:42:55] <Contract_Pilot> Neither of them tracking Numbers are in the right area.
[15:43:10] <Contract_Pilot> only 2 I got from new egg.
[15:44:26] <Wolf_> well the one in NY might just be one of the hubs
[15:45:19] <Wolf_> cause one of mine is worded the same but in CA
[15:45:50] <Wolf_> my other tracking number doesn’t even work
[15:45:59] <Contract_Pilot> But the one out for delivery in Texas?
[15:46:07] <Wolf_> that I dunno
[15:46:18] <Wolf_> could be USPS fuck up
[15:46:38] <Contract_Pilot> Sent them am e-mail via new egg system.
[15:46:51] <Contract_Pilot> they do now answer hahaha.
[15:47:00] <Contract_Pilot> Could be a USPS goof up.
[15:47:07] <Wolf_> I had something ship from <1hr away, it went to Fla, out for delivery, in/out of orlando 3x times, then back up to MD
[15:47:18] <Contract_Pilot> hahaha.
[15:50:47] <XXCoder> Wolf_: hardly the worse I saw. worse I saw was one guy who showed me picture of his package transit
[15:50:54] <XXCoder> it was orbiting his homecity
[15:51:24] <XXCoder> it went to 3 cities in turn 5 times in row before someone finally fixed it. none of those 3 cities is his home
[15:51:45] <XXCoder> it was "orbit" because it was going around and around his city
[15:53:24] <WZL> Hello from Argentina, does anybody know if there is a problem with the mesa store. I planned wrongly a purchase,thinking that would be a quick transaction but I can't get an estimated shipping date.
[15:56:31] <Wolf_> did you try emailing them?
[15:58:13] <WZL> yes several times, but there is no response
[15:58:48] <Wolf_> paging PCW / pcw_home
[16:00:47] <WZL> those are the mesa usernames in the irc chat?
[16:07:51] <MrSunshine> https://plus.google.com/photos/108164504656404380542/albums/5747722155741347649/5600023863571367666?pid=5600023863571367666&oid=108164504656404380542 hmm, this . .what is that ? is that an adjustment to make the X of the table go 90 degrees to the Y ?
[16:08:41] <MrSunshine> if so that is actualy quite neat .. never thought of that =)
[16:11:46] <enleth> that's one weird knee mill
[16:14:17] <LatheBuilder2> wzl, mesa customer service has been helpful the times I have talked to them on the phone. perhaps use skype or similar and phone the cust svc number?
[16:16:37] <MrSunshine> i think the X table is missing, looks like the swivel on a cross slide on a lathe, might be to be able to adjust the whole table out of or into alignment =)
[16:16:42] <WZL> I have this option in my "benchtop" mill but I never used it after the CNC conversion (is like this one http://molinarimaquinarias.com.ar/image051.jpg)
[16:19:54] <LatheBuilder2> wzl, what's your question?
[16:21:31] <WZL> I do not usually make telephone calls because I'm not confident enough of my english skills :( I have no doubt of the mesa support service. I'm afraid that they have not received my emails
[16:22:31] <WZL> I need to know the shipping date to tell it to the freight forwarder that will ship the package to my country
[16:22:40] <LatheBuilder2> i hear you. your written english is good. Mesa is on Pacific Time for what it's worth
[16:23:04] <WZL> right they are in california right?
[16:23:14] <LatheBuilder2> right
[16:23:19] <WZL> :)
[16:34:36] <Sync> WZL: if you still need help with the yaskawa drive, I know what is wrong with it
[16:34:50] <MrSunshine> https://www.youtube.com/watch?v=N1XwgdnA93I wth, is that how they did it in the olden days ? =)
[16:35:09] <MrSunshine> actualy quite and realy bad ass smart =)
[16:36:39] <WZL> YES !!!
[16:37:50] <WZL> I´m more than happy to hear that
[16:38:05] <Deejay> gn8
[16:38:30] <Sync> but you have to have very very good soldering skills to repair it without further damage
[16:39:46] <WZL> I am QFN good at soldering
[16:40:18] <zeeshan-lab> wow
[16:40:21] <zeeshan-lab> been a while
[16:41:44] <Sync> a desoldering iron is preferred
[16:42:02] <Sync> the problem are the capacitors near the gate drive hybrids
[16:42:03] <ReadError> chipquik
[16:42:18] <Sync> you need to swap those, and it'll be fine again
[16:42:30] <Sync> and mount a fan on the top of the drive
[16:42:36] <Sync> it is a stupid design
[16:43:21] <WZL> ok, electrolitics?
[16:44:08] <WZL> http://i.ytimg.com/vi/HkLvg1H0NtE/hqdefault.jpg
[16:44:40] <Sync> the small ones will need replacing, but I usually swap the big ones too
[16:45:06] <Sync> it is best to cut the capacitor away from the top and extract the pins seperately
[16:45:15] <Sync> as the holes are very tight
[16:45:50] <Wolf_> hot air gun works good for that sorta thing BUT sometimes will remove everything SMD as well
[16:45:57] <WZL> thanks a lot , I will try tonight. where are you from?
[16:46:32] <Sync> germany
[16:46:41] <Sync> you will need to replace them with high quality ones
[16:46:49] <Sync> 125°C preferred
[16:47:26] <WZL> I have a hot air rework station. In fact, I´m using the driver failure to bootstrap a lcnc conversion haha
[16:48:05] <WZL> do you know the value? may be I have some here in the office
[16:48:27] <Sync> maybe
[16:49:00] <andypugh> MrSunshine: That’s my mill. The table can swivel, and the X axis swivels with it.
[16:49:24] <MrSunshine> andypugh: yes, but Y is stationary ?
[16:49:36] <MrSunshine> its a kinda neat idea =)
[16:50:06] <MrSunshine> tho a well made machine would never have to be fixed for 90 degree i guess but its kinda neat that thing to be able to cut angles on big stuff =)
[16:50:10] <andypugh> It comes in very handy for one particular application, I can set the table to the hob angle when making gears: https://www.youtube.com/watch?v=PFTHY5U8v-U
[16:50:18] <MrSunshine> well, you can cut angles on big stuff anyways :P
[16:50:18] <MrSunshine> haha
[16:51:00] <andypugh> It started life as a manual machine, and that feature would have been handy for some jobs, I imagine.
[16:51:10] <Sync> sorry, can't find the value currently WZL
[16:52:37] <WZL> Don't worry sync you already made that good action of the day
[16:55:44] <WZL> I will try and return with news.
[16:57:56] <Tom_itx> WZL, see the smart ones are here now :)
[16:58:39] <Sync> just be careful that you don't damage the board with static
[16:58:55] <Sync> you can also work around the issue by turning the acceleration way down
[16:59:01] <Sync> but it will not position that way
[17:03:31] <WZL> I already try that (acceleration) it works better but usually fails at deceleration
[17:05:46] <WZL> Tom_itx : I see. I will frequent more this place.
[17:20:49] <JT-Shop> I'm Back!

[17:34:58] <zeeshan-lab> :D
[17:36:32] <zeeshan-lab> zeeshan@zeeshan-daq:~/apparatus$ uptime 18:12:24 up 111 days, 2:32, 3 users, load average: 0.07, 0.06, 0.05
[17:36:40] <zeeshan-lab> lol this poor lab comp
[17:36:43] <zeeshan-lab> been up for too long
[17:37:48] <PetefromTn_> Hey JT glad you made it back safely
[17:38:04] <jthornton> me too, we are a couple of tired puppies lol
[17:38:30] <jthornton> had a great time and it was good to meet up with you and put a face to the nick
[17:38:45] <PetefromTn_> yeah you too
[17:39:27] <jthornton> have you been to the italian rest in the valley?
[17:39:35] <PetefromTn_> no
[17:39:48] <jthornton> damm good pizza and italian cooking
[17:39:54] <PetefromTn_> oh yeah
[17:41:54] <malcom2073_> So question: I have a 5tpi ballscrew, 1.8degree per step motor, and 1/10th microstepping. Yet when I enter this into stepconf, it moves twice as far as it should
[17:42:20] <malcom2073_> Am I doing something wrong, or could be 1/10th microstepping drive actually be set to 1/5th (in which case, documentation is wrong)
[17:43:25] <jthornton> or double lead
[17:43:30] <zeeshan-lab> direct drive?
[17:44:32] <malcom2073_> Direct drive, what's double lead?
[17:44:37] <malcom2073_> These are 4 wire steppers fwiw
[17:44:47] <zeeshan-lab> 2 threads
[17:44:54] <zeeshan-lab> on the same lead screw
[17:44:54] <malcom2073_> Ohhhh
[17:45:16] <malcom2073_> Some oil and a rag should let me figure that out
[17:45:18] <zeeshan-lab> man im running my test apparatus
[17:45:21] <malcom2073_> clean it up, and run oil on a thread while spinning
[17:45:25] <zeeshan-lab> after 2 months
[17:45:25] <malcom2073_> yeah?
[17:45:29] <zeeshan-lab> and damn it works!
[17:45:39] <zeeshan-lab> its been sitting idling for so long, poor thing
[17:47:06] <malcom2073_> Nope, looks like single lead, 5 turns makes for 5 threads
[17:48:15] <PetefromTn_> zeeshan-lab hey man guess what
[17:48:19] <jthornton> what is the scale number that the wiz came up with?
[17:48:30] <zeeshan-lab> sup
[17:48:43] <PetefromTn_> it was a big day at the shop today LOL
[17:48:58] <PetefromTn_> ya know that motor that I have been doing all that machine work on?
[17:49:15] <zeeshan-lab> yes
[17:49:20] <PetefromTn_> lightened and clearanced rotors, studding, etc. etc.
[17:49:30] <PetefromTn_> well she fired up for the first time today!!
[17:49:36] <malcom2073_> jthornton: 10000steps/inch
[17:49:47] <PetefromTn_> I was chewin' my fingernails the whole time ;)
[17:50:05] <malcom2073_> 200 steps per rev, * 5 revs per inch * 10 microsteps == 10k
[17:50:09] <zeeshan-lab> nice man!!
[17:50:15] <zeeshan-lab> that musta been sweet to watch
[17:50:17] <PetefromTn_> she sounds MEAN
[17:50:32] <jthornton> does a 0.5 move make the stepper move one revolution?
[17:51:00] <PetefromTn_> its so revvy and nasty sounding LOL we were all grinning from ear to ear when it fired off...
[17:51:43] <PetefromTn_> I got a short vid..
[17:52:07] <malcom2073_> jthornton: No, a 0.5 move makes it move 2.5 revolutions or so
[17:53:10] <jthornton> sorry my math was wrong lol 0.2"
[17:53:38] <malcom2073_> Yep, 0.2 moves one revolution
[17:54:08] <jthornton> how far did the table move?
[17:54:28] <zeeshan-lab> PetefromTn_: any videos
[17:54:28] <malcom2073_> Huh... weird
[17:54:31] <malcom2073_> it's moving 0.2
[17:54:36] <malcom2073_> But in stepconf, it was moving twice as far as it should
[17:54:39] <malcom2073_> Oh I'm a total idiot
[17:54:44] <malcom2073_> 0.5 test area == 0.5 in either direction!
[17:54:45] <malcom2073_> :/
[17:54:52] <Wolf_> hah
[17:54:54] <jthornton> lol
[17:55:09] * malcom2073_ hangs head in shame, and runs linuxcnc test program in 3 axises to cheer myself uip
[17:55:09] <malcom2073_> :P
[17:55:12] * zeeshan-lab slaps
[17:56:09] <PetefromTn_> zeeshan yeah I got a short vid but not sure how to post it
[17:56:20] <Wolf_> could be worse I set my machine up first time and changed the step multiplier on the driver without power cycling and couldnt figure out why it wouldnt travel right distance
[17:56:36] <malcom2073_> heh
[17:58:48] <malcom2073_> NExt step, get air hooked up so I can operate the drawbar and get a tool in it!
[17:59:17] <zeeshan-lab> throw it on youtube
[17:59:29] <malcom2073_> 2 axis movement is on youtube
[17:59:43] <malcom2073_> 3 isn't anything special, just the quill whirring when it goes up and down :P
[18:03:08] <zeeshan-lab> andypugh: there? :D
[18:07:43] <zeeshan-lab> http://imgur.com/a/yfqc8
[18:07:58] <zeeshan-lab> check out the weird fractures
[18:12:31] <malcom2073_> Got air hooked up, we'll see if the lines hold pressure or explode heh
[18:13:20] <Wolf_> lol, that sounds promising
[18:13:50] <malcom2073_> They sat outside for over a year, possibly in the sunlight, plastic hard lines heh
[18:14:38] <Wolf_> least those are cheap to replace
[18:15:19] <malcom2073_> Yeah, probably get a roll of that stuff fairly cheap. That's on my shortlist to replumb anyway, I garuntee this line dryer and pressure regulator are shot heh
[18:15:52] <Wolf_> I had 200 feet of 3/8” plastic air line…
[18:16:25] <Wolf_> ended up running it from my garage down to the house lol
[18:17:07] <andypugh> zeeshan: Briefly
[18:19:42] <malcom2073_> lol
[18:23:02] <andypugh> zeeshan: Too late, time for me to log.
[18:23:12] <malcom2073_> Newp, hose failed at one of the brass compression fittings
[18:41:48] <malcom2073_> hmm, if I disable the spindle brake, I think I have enough air lines here todo this
[18:42:01] <malcom2073_> Don't need that anyway, Just have to be careful when running the impact drawbar heh
[18:54:02] <malcom2073_> whew
[18:54:12] <malcom2073_> just ran the knee up a foot and a half
[18:54:17] <malcom2073_> I need a knee motor
[18:59:00] <Jymmm> malcom2073_: you get exercise this way =)
[19:26:22] <malcom2073_> Jymmm: Psh
[19:26:28] <malcom2073_> I'm going CNC to *avoid* physical labor :-P

[23:58:27] <wolfmanjm> hi, I am trying to drive some Sumptor MB450 drivers from the parallel port. everythign looks like it is toggling, except the step signal goes from 5v to 1.2v which means it doesn;t step. do you need to use level converters or clever wirin gto get these to work?
[23:58:49] <wolfmanjm> (they are similar to leadshines)
