[00:03:10] <t12> i'm going to attempt to fix my headstock alignment with moglice
[00:03:49] <t12> apply moglice, put it on V ways, align spindle while its setting
[00:04:03] <t12> i wonder if this will work/be a disaster
[00:05:07] <t12> air bubbles will be hard to avoid
[00:05:39] <Tom_itx> vaccuum
[00:05:49] <t12> vacuum where?
[00:06:06] <Tom_itx> where you need it
[00:06:15] <t12> dont think i could seal around it
[00:06:25] <t12> the headstock V's were angle grinder fit
[00:06:40] <t12> i think their idea of headstock alignment was to leave the corners alone, make the rest concave
[00:06:50] <t12> then warp the entire headstock with bolt tension
[00:06:55] <t12> until its kinda aligned

[00:09:09] <MacGalempsy> never used moglice, but t12 that sounds like a potential disaster
[00:09:26] <t12> figure failre case i can grind out the moglice and i'll be where i started
[00:09:38] <t12> other option is to scrape it in
[00:09:47] <MacGalempsy> scraping is free
[00:09:58] <MacGalempsy> and if you over do it, then try moglice
[00:10:01] <t12> well, need carbide sharpening dodads
[00:10:13] <t12> wavy prolly +-.010 so LOTS of scraping
[00:10:22] <MacGalempsy> oh
[00:10:23] <t12> gotta go make, scrap prism refs
[00:11:00] <t12> gonna release compound on the bed, it seems fine
[00:11:15] <MacGalempsy> possible to remove and take in?
[00:11:22] <t12> the lathe?
[00:11:32] <t12> its all chinese project junk
[00:11:41] <t12> hence the fucked ways in the first place
[00:11:51] <Sync> t12: align before applying
[00:12:01] <Sync> drill a hole and inject
[00:12:22] <t12> hum
[00:12:25] <t12> i guess that is traditional way
[00:13:18] <Sync> you will also need to scrape the moglice
[00:13:27] <Sync> otherwise you will not get oil to stick to it
[00:13:38] <t12> this is static mount
[00:13:44] <Sync> then use DHW
[00:14:06] <MacGalempsy> what is the price on the moglice?
[00:14:11] <t12> cheap
[00:14:21] <t12> i think the whole order plus other junk is like $100
[00:14:23] <t12> and shipping
[00:14:32] <t12> this is a pretty small surface
[00:14:35] -!- mhaberler has quit [Quit: mhaberler]
[00:14:48] <Sync> careful, both of them need a min thickness
[00:15:02] <MacGalempsy> if it is that much, dont mix too much
[00:15:11] <MacGalempsy> 15min pot time
[00:15:11] <t12> whats the failure mode when thickness is wrong?
[00:15:18] <t12> i guess i can go measure it up
[00:15:34] <Sync> it will not really stick and not harden properly
[00:15:43] <Sync> or rather, it will harden
[00:15:45] <t12> i guess the headstock ways are already ground to shit, more wont hurt too much
[00:15:49] <Sync> but will be flexible
[00:15:57] <t12> gotcha
[00:16:04] <Sync> the best idea is to shim a gap for dhw
[00:16:23] <Sync> or insert a few grub screws
[00:16:46] <t12> like just lift the headstock off the bed however far and inject into that gap
[00:17:03] <t12> i guess i'll just need to shim up the tailstock to match but that's not too bad
[00:17:26] <t12> thnx for the advice
[00:17:34] <t12> i should have just tried the most conventional idea first :)

[00:28:41] <MacGalempsy> awesome
[00:29:04] <malcom2073_> Yep, gotta run power through some contactors for estop purposes, tidy up some wiring, and it should be ready to cut metal
[00:31:03] <Tom_itx> seems walmart still has steppers, just not at the 'clearance' price that it was
[00:32:47] <malcom2073_> Haha yeah, $122 iirc

[01:50:09] <t12> * DWH can be used as a near zero clearance filler under plates or between flush mounted components to fill
[01:50:12] <t12> potential gaps, providing 100% contact. In some areas (around screw holes) there will be physical contact
[01:50:15] <t12> between the surfaces, the DWH fills all other gaps. This technique is not recommended if there will be frequent
[01:50:18] <t12> disassembly of the components.
[01:50:21] <t12> ahh cool
[01:51:51] <t12> lol this table of thickness limits and application types
[01:52:03] <t12> and all permutations are the same numbers
[01:52:45] <PetefromTn_> Hey folks
[01:52:50] <PetefromTn_> whatsgoinon?
[01:53:16] <PetefromTn_> I have been helping my wife paint the entire living room and kitchen today so not been on here
[01:54:07] <PetefromTn_> but now I am trying to machine the exhaust flanges prototype
[01:54:29] <PetefromTn_> and I THOUGHT I had some 3/8-16 countersunk capscrews here but now I can't find them anywhere
[01:54:53] <PetefromTn_> but I found some button head screws
[01:55:17] <PetefromTn_> I wanted to use the countersunk screws to sort of located the part on the fixture
[01:56:01] <PetefromTn_> but the button heads are a good bit smaller than the holes I am locating with so I was trying to figure out some sort of thing I can put on the screw shank to take up the slack in the holes
[01:56:12] <PetefromTn_> so far I am coming up blank ;)

[01:57:37] <Wolf_> :P
[01:58:31] <PetefromTn_> hehehe smartass
[01:58:48] <PetefromTn_> still don't have a lathe
[01:59:02] <PetefromTn_> if I had a lathe I would already be done with the issue

[02:09:37] <Wolf_> well, this should be interesting, gonna try to revive a Mp9 renishaw and interface it with OMM unit and a Mi4 box
[02:13:52] * zeeshan wants a probe
[02:14:42] <Wolf_> well I got the mp9 for $75, OOM for $84
[02:14:47] <Wolf_> OMM*
[02:15:46] <zeeshan> how
[02:15:50] <Wolf_> ebay
[02:16:08] <zeeshan> ive never seen them go less than 400
[02:16:30] <Wolf_> Mp9 was listed as parts/not working
[02:16:34] <zeeshan> ah
[02:16:41] <zeeshan> havent seen it like that either
[02:16:44] <Wolf_> not sure why the OMM went for so low lol
[02:17:44] <Wolf_> http://www.ebay.com/itm/291587543328
[02:18:09] <zeeshan> nice
[02:18:14] <zeeshan> link to mp9?
[02:18:15] <zeeshan> :D
[02:18:28] <MacGalempsy> well shit
[02:18:47] <Wolf_> http://www.ebay.com/itm/111779639915
[02:19:18] <zeeshan> cheap
[02:19:41] <Wolf_> doesn’t look like its been crashed too hard
[02:19:57] <MacGalempsy> my x motor is not acting right. I messed with some tuning, then it started having problems. no crashes. then it started working right, then hit the eswitch and now it wont start back up. so I took off the motor cover and messed with the connection and its started
[02:21:23] <Tom_itx> Wolf_, the switches are all you need right?
[02:21:24] <MacGalempsy> ran it for a bit, then hit the estop, now it wont start again. I thought it was a connection issue but that doesnt seem to be the case
[02:21:25] <Tom_itx> on that
[02:21:35] <MacGalempsy> any ideas?
[02:21:44] <Tom_itx> if the probe switches are good you can hook it up
[02:21:45] <Wolf_> Tom_itx: ?
[02:21:58] <Tom_itx> that link said for parts
[02:22:01] <Wolf_> yeah, at worst just convert it to wired probe
[02:22:10] <Tom_itx> did you get it?
[02:22:21] <Wolf_> at best get it working with the OMM
[02:22:37] <Wolf_> yeah, I sent a offer in at $70 and they took it lol
[02:23:51] <Tom_itx> been abused a bit
[02:24:16] <zeeshan> tom did you have a carrying case
[02:24:24] <zeeshan> *do ; for your telescope
[02:24:29] <Tom_itx> oh, no
[02:24:33] <Tom_itx> i keep it in the box
[02:24:39] <Tom_itx> with the packing
[02:24:42] <zeeshan> hm
[02:24:47] <zeeshan> my tube and base seperate
[02:24:51] <Tom_itx> since i don't use it all that much
[02:24:52] <zeeshan> so im thinking of getting a case for the tube
[02:24:55] <Tom_itx> 3 boxes
[02:25:00] <zeeshan> because i cant fit it in the car
[02:25:01] <zeeshan> assembled
[02:25:05] <Tom_itx> yeah
[02:25:19] <Tom_itx> lense box
[02:25:24] <Wolf_> some day I need to try my scope out
[02:25:26] <zeeshan> do you keep air?
[02:25:27] <Tom_itx> stand and scope
[02:25:30] <zeeshan> a can of air
[02:25:34] <zeeshan> to clean your lens
[02:25:34] <Tom_itx> naw
[02:25:35] <zeeshan> etc
[02:25:41] <zeeshan> just blow w/ your mouth?
[02:25:42] <zeeshan> :D
[02:25:44] <Tom_itx> i have one somewhere but not for that
[02:27:23] <Tom_itx> i wanted to get a filter to look at the sun but never have
[02:27:33] <zeeshan> :D
[02:30:55] <Wolf_> is it bad that I’m not even sure what telescope I have lol

[02:33:05] <Tom_itx> more like that
[02:33:07] <Tom_itx> but older
[02:35:20] <Wolf_> I even have a T mount and what not for my dslr to use with it, haven’t even take it outside at night yet lol
[02:35:49] <Tom_itx> i have a camera mount
[02:36:07] <Tom_itx> somewhere..
[02:40:56] <zeeshan> wolf just admitted
[02:40:59] <zeeshan> he got his telescope to perv
[02:41:00] <zeeshan> !
[02:41:05] <zeeshan> =D
[02:41:13] <zeeshan> ok im going to go gazing
[02:41:15] <zeeshan> see what i can find
[02:41:19] <Wolf_> my (ex)gf saw that I had a 90mm Maksutov-Cassegrain on my amazon wish list and got me the nexstar… she didn’t know I had the 90mm Mak on there cause I wanted it to make a video spotting scope / camera lens
[02:41:30] <Tom_itx> zeeshan
[02:41:32] <Tom_itx> hint:
[02:41:37] <Tom_itx> look UP!
[02:41:52] <zeeshan> lol

[02:48:57] <Tom_itx> Saturn will disappear from the evening sky in November 2015 and will reappear in the morning sky in December 2015.
[02:49:02] <Tom_itx> better catch it while you can

[04:18:31] <XXCoder> bah
[04:18:32] <XXCoder> http://www.calgraphix.com/wp-content/uploads/2013/03/Engineering-drawing.png
[04:18:40] <XXCoder> I ran into problems designing that in freecad
[04:18:49] <Connor> What problem ?
[04:19:04] <XXCoder> not sure how to design the standoff for round attachment point
[04:19:35] <XXCoder> expecially the bottom part, it shows seamless connection to circle but not sure how to define stuff so it looks proper
[04:20:11] <Connor> I don't know much about freecad.
[04:20:29] <XXCoder> no plm
[04:21:13] <Wolf_> all I know is I could draw that up pretty quick in solidworks...
[04:21:13] <XXCoder> mine incorrectly has hole cenetr ~32mm away from specific edge
[04:21:18] <XXCoder> it should be 36
[04:21:48] <XXCoder> Wolf_: how do I figure length so edge to hole is correct angle AND support is flush with cyl?
[04:22:30] <Wolf_> eh?
[04:23:02] <XXCoder> diffult to explain hmm
[04:23:22] <Wolf_> that bottom upright?
[04:23:43] <Wolf_> er bottom edge of the upright part
[04:23:55] <Wolf_> support… thinger
[04:24:10] <XXCoder> yeah the part that attaches to cyl is problem to me
[04:24:45] <Wolf_> well, I know how I would draw it, but its probably not the right way lol
[04:25:34] * zeeshan tries to draw that
[04:25:45] <Wolf_> lol race?
[04:25:52] <zeeshan> lets do it!
[04:26:27] <XXCoder> whomever posts picture wins hmm props'
[04:29:44] <XXCoder> well I cheated and did a visual blend of support to cyl
[04:34:05] <zeeshan> what is this silly thing anyway
[04:34:21] <XXCoder> no idea
[04:34:29] <XXCoder> just googled engineering drawing
[04:35:30] <zeeshan> http://i.imgur.com/19Qwr9M.png.
[04:35:32] <zeeshan> done!
[04:35:44] <XXCoder> nice
[04:35:49] <Wolf_> dammit loading it right now
[04:36:21] <XXCoder> HMM I see a problem
[04:36:30] <XXCoder> yours do not blend at bottom
[04:36:36] <zeeshan> what blend
[04:36:42] <Wolf_> http://i.imgur.com/Uac1MdJ.png?1
[04:36:55] <zeeshan> i win win win!!
[04:36:55] <zeeshan> :D
[04:37:14] <XXCoder> probably acceptable for whatever its used for though zeeshan lol
[04:37:17] <Wolf_> I was done when you linked it lol

[04:40:41] <XXCoder> Wolf_: how did you dermine length so it blends properly?
[04:40:45] <XXCoder> I just did visual

[04:40:53] <zeeshan> XXCoder: offset a plane
[04:40:58] <zeeshan> from the centerline
[04:41:01] <zeeshan> and use pierce?
[04:41:06] <zeeshan> ( dunno if you have pierce)
[04:41:19] <XXCoder> dunno too. freecad is nice but not magical
[04:42:04] <zeeshan> http://i.imgur.com/gRZuaS8.png
[04:42:06] <zeeshan> like that
[04:42:32] <Wolf_> http://i.imgur.com/s9U9dYE.png?1
[04:42:41] <Wolf_> I did it totally different
[04:43:19] <XXCoder> interesting
[04:44:18] <zeeshan> you removed material?
[04:44:39] <Wolf_> I drew the top down and then used extrude cut to make the shape lol
[04:44:48] <zeeshan> thjat works :D
[04:45:01] <XXCoder> I did this before https://hackadaycom.files.wordpress.com/2013/12/engineeringdrawing.png
[04:45:09] * Wolf_ really has no cad training
[04:45:10] <XXCoder> took me while to figure some stuff lol
[04:45:13] <XXCoder> like that slot
[04:45:21] <zeeshan> wolf
[04:45:29] <zeeshan> here's a test to see if you've done it right
[04:46:03] <zeeshan> go to your first sketch
[04:46:07] <zeeshan> change 56 to 88
[04:46:27] <zeeshan> if it breaks
[04:46:29] <zeeshan> er
[04:46:34] <zeeshan> change 56 to 45
[04:46:43] <Wolf_> oh yeah, it will break :P
[04:46:49] <XXCoder> mine broke yeah
[04:46:53] <zeeshan> 88 will break cause its self intersecting
[04:46:57] <zeeshan> but it shouldnt break w/ 45
[04:47:03] <XXCoder> the support didnt change with base chanhge
[04:47:29] <zeeshan> try to figure out why it breaks
[04:47:32] <zeeshan> and fix the constraints
[04:47:41] <Wolf_> hmm
[04:48:44] <Wolf_> its constrained...
[04:49:14] <Wolf_> but I did fuck up on the bottom slot, should have did that as a extruded cut with a center point constraint
[04:49:56] <Wolf_> and the holes as well
[04:50:39] <Wolf_> oddly I have learn a lot by downloading product cads from mcmaster carr lol
[04:52:17] <zeeshan> hehe
[04:52:20] <zeeshan> dont stress
[04:52:28] <zeeshan> i come across this on our standard products at work
[04:52:36] <zeeshan> a 2 min change becomes a 2 hour job
[04:52:43] <zeeshan> its frustrating
[04:53:03] <zeeshan> for some reason a lot of people like to draw
[04:53:08] <zeeshan> from bottom corner
[04:53:12] <zeeshan> instead of making it symmetric
[04:53:43] <Wolf_> yeah, I have started to use the mirror function a lot
[04:53:57] <zeeshan> when i got taught in school, my instructor (really good) said:
[04:54:16] <zeeshan> symmetry, least # of steps, check if it breaks when you change a possible design change dimension
[04:54:31] <zeeshan> if you can follow those, your model will be really robust
[04:55:23] <Wolf_> it makes it easy as hell in SW with use of math functions in the parameters entry boxes too
[04:55:32] -!- aventtini6 [aventtini6!~sad@5-12-129-90.residential.rdsnet.ro] has joined #linuxcnc
[04:55:41] <zeeshan> yes
[04:55:47] <zeeshan> but honestly, i dont usuaully use those
[04:55:54] <zeeshan> unless im making different instances of the same thing
[04:56:08] <zeeshan> an example would be like a bolt that changes length
[04:56:09] <zeeshan> but thats it
[04:56:19] <zeeshan> 99% is constraints
[04:56:38] <zeeshan> it all depends at the end of the day what youre trying to do :P
[04:56:49] <zeeshan> we have enclosure doors at work which have different options:
[04:56:58] <Wolf_> I mean for the base parts, like 75mm wide part just shove 75/2 in the length
[04:57:02] <zeeshan> 2 lights, 3 lights, fan cutout, interlock cutout, breaker cut out
[04:57:12] <zeeshan> doors will have a combination of those
[04:57:13] <Wolf_> cause i’m lazy
[04:57:19] <zeeshan> its all formulas mostly for that
[04:57:41] <zeeshan> you could do that
[04:57:51] <zeeshan> but right click on the width line and select mid point
[04:58:03] <zeeshan> and then constrain it using vertical or horizontal constraint to the origin
[04:58:53] <Wolf_> yup
[04:59:12] <Wolf_> slowly learning that stuff as I need to change things I have drawn up lol
[04:59:36] <zeeshan> only way to learn cad :P
[04:59:51] <zeeshan> if you get time
[04:59:55] <zeeshan> and if you havent already
[05:00:01] <zeeshan> do all of the included solidworks tutorials
[05:00:11] <zeeshan> they'll really make you pro
[05:00:15] <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...
[05:02:03] <Wolf_> was a “wtf did I mess up” moment looking at ! on every part in the stack
[05:02:14] <zeeshan> hehe
[05:02:45] -!- dimas_ has quit [Read error: Connection reset by peer]
[05:03:06] <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
[05:03:32] <zeeshan> its awesome when it all grows and shrinks together
[05:03:40] <zeeshan> and all the assembly parts are in harmony
[05:04:00] <Wolf_> http://i.imgur.com/Q1gnbtV.png?1 :D
[05:04:36] <zeeshan> nice
[05:04:42] <zeeshan> lots of mcmaster carr parts:d
[05:04:47] <zeeshan> that stepper mount is crazy looking
[05:04:49] <zeeshan> i like
[05:04:52] <Wolf_> yeah
[05:05:04] <Wolf_> thats for the X2

[05:07:52] <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 
[05:08:42] <zeeshan> nice
[05:09:00] <Wolf_> except that the china eBay vendor sent me a sleeve of bearings with 1 5mm and 9 4mm bore lol
[05:09:32] <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
[05:10:36] <Wolf_> and this is a good example to why to model first then make parts http://i.imgur.com/GgJEngr.png?1 lol
[05:14:22] <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. "
[05:14:26] <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
[05:19:33] <XXCoder> Wolf_: nice but why is it offset

[05:21:40] <Jymmm> Wolf_: And if it's still too short, cut it again until it's not!
[05:22:04] <XXCoder> yeah just cut at negative distance. no problem!
[05:24:41] <Wolf_> heh, that part doesn’t look that bad to cad out either XXCoder
[05:25:03] <XXCoder> yeah will try it when done changing part so changing stuff does not break it

[05:27:06] <zeeshan> darn :P
[05:27:08] <zeeshan> okay early bed time

[07:06:37] <XXCoder> or 32 diameter
[07:11:48] <Wolf_> 32 rad for the nose on that plane

[07:38:56] <wicki> anybody in here, who can tell me, where to find an iso-image of "Latest releases: 2.7.1" ?
[07:39:21] <wicki> 2.7. results in segfault at startup :-(
[07:40:58] <XXCoder> hey Wolf_ that image
[07:41:08] <Wolf_> http://www.linuxcnc.org/linuxcnc-2.7-wheezy.iso ?
[07:41:22] <XXCoder> it says 51 mm height from top to surface top at back but I may be getting it wrong?
[07:42:27] <Wolf_> 90mm up the 60° part, then 51mm+32mm rad
[07:42:41] <wicki> Wolf: 2.7. does not boot here - segfault at start of xserver
[07:44:11] <wicki> 2.7.1 is anounced - but I am unable to find it
[07:44:17] <XXCoder> Wolf_: no, the other end - the dual round connectors, I'm been trying to figure the overall height including curved top
[07:44:40] -!- nofxx has quit [Ping timeout: 244 seconds]
[07:44:41] <Wolf_> oh, 51mm to the centerline of the bore
[07:44:48] <XXCoder> at that end it says 51 but it doesnt show where other point is.
[07:44:53] <XXCoder> one is center of holes
[07:45:23] <XXCoder> I tried bottom of part to center bore, looks correct
[07:45:35] <Wolf_> so to teh top would be 51mm+19mm
[07:45:42] <XXCoder> indeed

[09:48:45] <fenn> me
[09:51:58] <XXCoder> cool
[09:52:00] <fenn> anyone could make these demo products if they would actually sell the displays
[09:52:49] <fenn> the technology has been around forever, it's been limited mostly by bad licensing strategies
[10:00:58] <fenn> the screen update is actually a lot faster than their demo
[10:01:15] <XXCoder> some of screens is quite fast
[10:01:25] <XXCoder> almost enough to play movie
[10:01:32] <XXCoder> grayscale one but yeah
[10:01:37] <fenn> yes i have seen people playing sonic the hedgehog at 15 fps
[10:01:48] <fenn> uses lots of battery if you do that though
[10:01:55] <XXCoder> I bet
[10:03:10] <fenn> i want to do wallpaper that you "paint" on images with an electric "digital paint" roller

[10:03:38] <XXCoder> yeah
[10:04:00] <XXCoder> very fast for not using norefresh type
[10:04:20] <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
[10:04:34] <XXCoder> how is it made anyway
[10:05:20] <fenn> microfluidic encapsulation of beads in a droplet of liquid and then again in a hardening polymer i think
[10:06:41] <fenn> if three channels join, the two outer channels become the outer layer
[10:08:04] <fenn> like this http://youtu.be/0sde48D2eFs
[10:09:39] <XXCoder> hmm
[10:10:06] <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

[10:54:47] <XXCoder> newbie tech still though, lets see if it gets to market.
[10:56:36] <SpeedEvil> fenn: It's depressing.
[10:57:11] <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
[10:57:41] <XXCoder> SpeedEvil: Sony once showcased watch that shows face in ink... and entire band too
[10:57:52] <XXCoder> nothing come of it so far
[10:58:41] <fenn> xxcoder are you talking about the qualcomm/mirasol technology?
[10:59:42] <XXCoder> looks like yes
[10:59:52] <fenn> well i dunno what the hell their problem is
[11:00:15] <fenn> spend $2B and nothing to show for it but a single ebook reader
[11:01:03] <SpeedEvil> Mirasol I don't think can work
[11:01:14] <SpeedEvil> It's a fundamentally flawed technology - from what I remember
[11:01:26] <SpeedEvil> It works in principle OK if tehre is a single bright point-source of light.
[11:01:30] <SpeedEvil> Otherwise, not.
[11:01:33] <fenn> http://teleread.com/chris-meadows/mirasol-pixel-qi-where-are-they-now/
[11:01:36] <XXCoder> interesting
[11:01:42] <SpeedEvil> One of those things that works well for demos.
[11:02:46] <fenn> when i use an e-ink display i'm either 1) outside, or 2) sitting in my reading chair with an overhead lamp
[11:03:03] <fenn> so i don't see the problem
[11:03:12] <SpeedEvil> I live in scotland.

[11:08:39] <XXCoder> kit with raspberry
[11:08:44] <XXCoder> or maybe not raspberry
[11:09:05] <Topy44> quick engineering question, i am designing a changeable-head-system for a 3d printer
[11:09:20] <fenn> kinematic mount!
[11:09:22] <Topy44> i need to design a mechanism to quickly and securely fasten the heads to the x carriage
[11:09:28] * fenn turns on the broken record
[11:09:51] <Topy44> traditional cartesian printer
[11:10:31] <Topy44> the mount should be lasercutable or at least 3d printable
[11:10:38] <malcom2073_> Topy44: Thingiverse has stuff for that I'm sure
[11:10:42] <SpeedEvil> Use one head, and exchange the nozzles
[11:10:44] <Topy44> nothing good that i could find
[11:10:52] <malcom2073_> I'd use a camlock, similar to how camera mounts work though, not sure how laser cuttable that is
[11:10:52] <Topy44> SpeedEvil: no i have mutliple hotends and extruders
[11:10:58] <fenn> Topy44: http://www.g2-engineering.com/technology-kinematics
[11:10:59] <Topy44> for 1.75mm and 3mm and so on
[11:11:11] <Topy44> malcom2073_: you mean like a dovetail thing?
[11:11:18] <malcom2073_> Topy44: Yes
[11:11:30] <Topy44> fenn: i do not see how this relates to my question
[11:11:39] <fenn> the goal is to have repeatable positioning, yes?
[11:11:42] <Topy44> malcom2073_: thats what i thought too, but yeah, not really laser-cuttable
[11:11:43] <Topy44> well
[11:11:44] <SpeedEvil> fenn: then your fu is weak.
[11:11:53] <Topy44> Z positioning has to be repeatable
[11:11:59] <Topy44> XY is not critical
[11:12:06] <Topy44> (1mm or so is good enough)
[11:12:26] <Topy44> Z is important because of the Z end stop, so it should be precise to about .05mm
[11:12:36] <fenn> the page is exactly what i wanted, just read it
[11:13:23] -!- skunksleep has quit [Ping timeout: 264 seconds]
[11:13:32] <malcom2073_> Topy44: Your printer's Z likely isn't accurate to 0.05 fwiw, especially if it's unsupported smooth rod :P
[11:13:46] <malcom2073_> But yeah, dovetail and camlock
[11:13:54] <malcom2073_> 3d printable though
[11:13:57] <Topy44> i'd argue it is actually
[11:14:32] <SpeedEvil> Topy44: have you computed the beam sag?
[11:14:37] <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.
[11:14:39] <Topy44> Z uses a ballscrew plus smooth rod for positioning
[11:14:55] <Topy44> malcom2073_: ofc
[11:15:10] <Topy44> but that doesn't matter
[11:15:16] <fenn> i've seen 20 micron layer height prints, looked ok
[11:15:23] <Topy44> as the z end stop is part of the x carriage
[11:15:35] <SpeedEvil> fenn: that means you have 20 micron repeatability at a given point.
[11:15:42] <fenn> yes
[11:15:51] <SpeedEvil> fenn: it does not mean you have 20 micron flatness across the bed
[11:15:55] <fenn> certainly not
[11:16:00] <malcom2073_> Topy44: My point is: It'sgoing to be as accurate as anything you solid mount down (dovetail/camlock for instance) :)
[11:16:02] <Topy44> the important thing is that the position of the hotend to the end stop is repeatable
[11:16:30] <SpeedEvil> this is somewhat more important because if you're swapping hotends, the weights may vary
[11:16:32] <Topy44> yes, dovetail/camlock does sound good, however its not laser cutable
[11:16:47] <malcom2073_> True, ask in #reprap, they're better at coming up with hacks instead of solutions though
[11:16:48] <Topy44> SpeedEvil: again, the endstop sensor is _on the carriage_
[11:16:56] <Topy44> so any bend in the x axis will be compensated
[11:17:35] <Topy44> malcom2073_: the very reason i am asking here and not in #reprap :)
[11:18:27] <SpeedEvil> Steel ball bearings registering in holes, drawn up by a bolt may be quite adequate
[11:18:28] <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
[11:18:42] <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
[11:18:52] <Topy44> actually that could work, yes
[11:18:56] <fenn> the dowel pins provide the v-groove that the ball bearings sit in
[11:19:06] <malcom2073_> Dowel pins are a good idea for repeatable positioning
[11:19:14] <malcom2073_> Dowels to align, bolts to secure
[11:19:19] <fenn> malcolm that's not what i'm saying at all
[11:19:32] <malcom2073_> fenn: I didn't say it was
[11:19:47] <malcom2073_> You're using them sideways
[11:19:55] <fenn> it's frustrating when everyone is trying their hardest to ignore what i'm saying
[11:20:05] <Topy44> i'm not :(
[11:20:22] <Topy44> trying to understand your suggestion
[11:21:04] <Topy44> hm, i guess if i make a nice jig i could laser cut dovetails
[11:21:18] <Topy44> or the dowel pin setup
[11:21:19] <Topy44> hrm
[11:21:25] <Topy44> yeah this gives me some ideas
[11:21:29] <malcom2073_> I think fenn is suggesting instead of dovetails, use three dowels, two to form the "v", and one to go in it
[11:21:30] <malcom2073_> ?
[11:22:58] <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
[11:23:39] <fenn> those discs are neodymium magnets but you could instead use a cam in the center to provide holding force
[11:30:01] <Jymmm> Eh, alignment pins and wingnuts.
[11:31:50] <Jymmm> Repeatable positioning and quick to swap out.

[14:22:09] <_methods> are tools hangin up when it does a tool change?
[14:22:19] <enleth> as in, the angle is OK, no bellmouthing, but lots of scratches and pitting
[14:22:24] <_methods> or is it so bad it can't complete?
[14:22:53] <_methods> well i wouldn't do anything crazy unless it was actually interfering with tool changes
[14:23:04] <enleth> it's too loose I think, due to uneven surface
[14:23:05] <_methods> and get a spindle wiper
[14:23:10] <_methods> oh
[14:23:21] <_methods> cat 40?
[14:23:30] <enleth> and I guess there are high spots in there
[14:23:39] <enleth> QC30
[14:23:50] <fenn> use a rounded abrasive stick to take off the high spots?

[14:25:57] <enleth> so far I had some dirty oil act as accidental engineer's blue and it looks bad

[14:32:54] <Sync> if you trust the control you can just hard turn the taper enleth
[14:32:56] <ssi> I then spent a bunch of time making a flask, including turning alignment pins for it
[14:33:02] <Sync> and sneak up on it
[14:33:02] <ssi> making a screen, screening sand, mixing greensand
[14:33:10] <ssi> then I tried to make a mold, and learned a couple things:
[14:33:16] <ssi> 1) my sand is too dry
[14:33:42] <ssi> 2) 50lb sand isn't enough to fill a 12x10x11" flask
[14:33:59] <fenn> switch to lost foam, your back will thank you
[14:34:05] <renesis> damn, rly?
[14:34:13] <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
[14:34:24] <ssi> so I glued some 1/4" strips inside in place of the groove
[14:34:25] <renesis> i dont think lost foam eliminates the sand?
[14:34:33] <ssi> lose a little interior volume that way but it'll work
[14:34:52] <fenn> don't worry, the sand will fall out of the cope even with the key
[14:35:03] <Wolf_> lost foam/pla/wax means you don’t need to lift half the flask

[20:05:16] <MrSunshine> but i know something is moving, got 0.2mm about if i push the axis in play
[20:05:31] <MrSunshine> but i have to push hard
[20:05:53] <Wolf_> there is a end block with 2 bearings in it right?
[20:05:59] <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

[20:09:49] <Wolf_> yeah I plowed a chunk of alum right though a 7/16” end mill, didn’t even slow down
[20:10:01] <MrSunshine> andypugh: any tips ? =)
[20:10:05] <Wolf_> broke the end mill in half lol
[20:10:10] <andypugh> Don’t be too afraid
[20:11:47] <andypugh> MrSunshine: Terribe photo, but: https://picasaweb.google.com/lh/photo/4UHtgZQZ8-sR_AE8DnpE2NMTjNZETYmyPJy0liipFm0?feat=directlink
[20:12:46] <Contract_Pilot> Anyone get their new egg order?
[20:13:00] <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.
[20:13:10] <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
[20:13:27] <Contract_Pilot> Mine is showing out for delivery in Houston TX i am in vancover, WA
[20:13:42] <Wolf_> lol
[20:13:46] <Wolf_> thats not good
[20:13:47] <XXCoder> lol
[20:13:48] * SpeedEvil is awaiting cancellation confirmation for 36 quadcopters at $1.99
[20:13:52] <XXCoder> also, vancouver sucks :P
[20:13:57] <XXCoder> lived there for long time
[20:14:07] <Wolf_> I got one of my new egg motors
[20:14:20] <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.
[20:14:24] <XXCoder> SpeedEvil: tiny ones? lol
[20:14:38] <Contract_Pilot> Wonder if they just got the tracking #'s mixed up.

[20:17:27] <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

[20:19:14] <Contract_Pilot> only 2 I got from new egg.
[20:20:29] <Wolf_> well the one in NY might just be one of the hubs
[20:21:22] <Wolf_> cause one of mine is worded the same but in CA
[20:21:54] <Wolf_> my other tracking number doesn’t even work
[20:22:03] <Contract_Pilot> But the one out for delivery in Texas?
[20:22:10] <Wolf_> that I dunno
[20:22:22] <Wolf_> could be USPS fuck up
[20:22:41] <Contract_Pilot> Sent them am e-mail via new egg system.
[20:22:55] <Contract_Pilot> they do now answer hahaha.
[20:23:04] <Contract_Pilot> Could be a USPS goof up.
[20:23:10] <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

[20:44:45] <MrSunshine> if so that is actualy quite neat .. never thought of that =)

[21:16:22] <zeeshan-lab> wow
[21:16:24] <zeeshan-lab> been a while
[21:17:48] <Sync> a desoldering iron is preferred
[21:18:05] <Sync> the problem are the capacitors near the gate drive hybrids
[21:18:06] <ReadError> chipquik
[21:18:22] <Sync> you need to swap those, and it'll be fine again
[21:18:33] <Sync> and mount a fan on the top of the drive
[21:18:40] <Sync> it is a stupid design
[21:19:24] <WZL> ok, electrolitics?
[21:20:11] <WZL> http://i.ytimg.com/vi/HkLvg1H0NtE/hqdefault.jpg
[21:20:43] <Sync> the small ones will need replacing, but I usually swap the big ones too
[21:21:09] <Sync> it is best to cut the capacitor away from the top and extract the pins seperately
[21:21:18] <Sync> as the holes are very tight
[21:21:54] <Wolf_> hot air gun works good for that sorta thing BUT sometimes will remove everything SMD as well
[21:22:01] <WZL> thanks a lot , I will try tonight. where are you from?
[21:22:36] <Sync> germany
[21:22:45] <Sync> you will need to replace them with high quality ones
[21:22:52] <Sync> 125°C preferred
[21:23:30] <WZL> I have a hot air rework station. In fact, I´m using the driver failure to bootstrap a lcnc conversion haha
[21:24:09] <WZL> do you know the value? may be I have some here in the office
[21:24:31] <Sync> maybe
[21:25:04] <andypugh> MrSunshine: That’s my mill. The table can swivel, and the X axis swivels with it.
[21:25:28] <MrSunshine> andypugh: yes, but Y is stationary ?
[21:25:40] <MrSunshine> its a kinda neat idea =)
[21:26:09] <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 =)
[21:26:14] <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
[21:26:21] <MrSunshine> well, you can cut angles on big stuff anyways :P
[21:26:22] <MrSunshine> haha
[21:27:03] <andypugh> It started life as a manual machine, and that feature would have been handy for some jobs, I imagine.
[21:27:14] <Sync> sorry, can't find the value currently WZL
[21:28:40] <WZL> Don't worry sync you already made that good action of the day
[21:31:48] <WZL> I will try and return with news.
[21:34:00] <Tom_itx> WZL, see the smart ones are here now :)
[21:34:43] <Sync> just be careful that you don't damage the board with static
[21:34:59] <Sync> you can also work around the issue by turning the acceleration way down
[21:35:05] <Sync> but it will not position that way
