Back
[00:41:53] <XXCoder> failure heh
[02:47:45] <Deejay> moin
[02:49:20] <XXCoder> hey
[03:37:34] <XXCoder> editing videos to upload whee
[05:10:07] <XXCoder> https://youtu.be/sojJgCfDbp4
[05:10:08] <XXCoder> enjoy
[05:10:17] <XXCoder> archivist: check it out lol
[05:26:19] <jthornton> morning
[05:28:34] <XXCoder> jthornton: hey
[05:28:40] <XXCoder> did you see video link lol
[05:29:23] <jthornton> no
[05:30:12] <XXCoder> https://youtu.be/sojJgCfDbp4
[05:31:51] <jthornton> take shorter cuts and allow time for the nylon to cool
[05:32:25] <XXCoder> yeah, it was many problems, though I could have added bunch of M0s to help tool cool
[05:32:51] <SpeedEvil> Tool to cool surely?
[05:32:55] <XXCoder> it was my first nylon lol (outside work, which i got those disks)
[05:33:11] <SpeedEvil> Very sharp tooling and coolant?
[05:33:20] <XXCoder> work machine just dump shitton of coolant
[05:33:31] <XXCoder> SpeedEvil: yeah very sharp tool
[05:33:43] <XXCoder> rpm is an issue too, though its just too fast
[05:33:56] <jthornton> yea a single flute onshrud end mill
[05:33:59] <XXCoder> I tried to slow it down a bit but it jammed few times
[05:34:06] <SpeedEvil> Is there coolant on there?
[05:34:15] <XXCoder> nope, my machone dont have coolant anything
[05:34:24] <XXCoder> no air no nothing. I need to add air lol
[05:34:40] <XXCoder> though that vise was awesome!
[05:34:56] <SpeedEvil> Or just spray with a little garden sprayer even
[05:35:10] <XXCoder> cant spray anything in downstairs living room unfortunately
[05:35:14] <jthornton> another thing I do if possible is to machine a couple of flats on the od so it has better grip in the vise
[05:35:24] <XXCoder> I use cardboard boxes to keep chips limited but i clean up afterwards
[05:35:30] <SpeedEvil> sure you can spray
[05:35:32] <SpeedEvil> clean water
[05:35:43] <XXCoder> I still need to move it to garage lol
[05:35:54] <SpeedEvil> It's not perhaps the completely ideal coolant - but it's a hell of a lot better than nothing
[05:35:57] <XXCoder> SpeedEvil: yeah but then its near LOTS stuff I dont wanna get water
[05:36:15] <XXCoder> its hella inconvient place to run router :(
[05:36:16] <SpeedEvil> Also, you can in principle stick the nylon in the freezer
[05:36:41] <SpeedEvil> I don't know how much that'd help, but it seems like it might a little
[05:36:49] <XXCoder> I got an idea lol
[05:36:54] <XXCoder> dumb idea maybe?
[05:37:08] <XXCoder> AC running coldest possible, full blast down to stock and tool
[05:37:13] <XXCoder> air cooling
[05:37:19] <XXCoder> with really cold air
[05:37:29] <SpeedEvil> Probably not any more helpful than room air at very high speed
[05:37:51] <SpeedEvil> also - compressor will eject colder than room air
[05:38:08] <XXCoder> SpeedEvil: though if I did that project again, I would add lots M0 to cool tool
[05:38:23] <XXCoder> say dig down, go up, m0 for a bit, go down finish
[05:38:35] <XXCoder> since it cooled off it would finish hell of a lot cleaner
[05:38:46] <SpeedEvil> yeah
[05:38:46] <XXCoder> is there any gcode for say "wait for a minute"
[05:38:57] <SpeedEvil> pecking really hard
[05:39:11] <SpeedEvil> you want really big chips.
[05:39:29] <XXCoder> its on 1/16 microstepping, weirdly enough
[05:39:29] <SpeedEvil> Because heating is more-or-less proportional to inverse chip size
[05:39:38] <XXCoder> board setting is on 1/8
[05:39:49] <XXCoder> I got no idea why its like that
[05:40:19] <XXCoder> so glad I checked after repair (Y got loose and was slipping so badly)
[05:41:01] <XXCoder> SpeedEvil: yeah I guessed so, it was making fairly good chip sizes before I had to increase rpm to prevent jams (it wouldnt happen if it had waited)
[05:41:21] <XXCoder> nylon is weird
[05:41:47] <archivist> not allowing chip clearance, poor spindle motor
[05:42:21] <XXCoder> very poor spindle indeed. I learned a lot though heh
[05:45:01] <XXCoder> so guys peck would have done better?
[05:45:18] <XXCoder> though that em is NOT center cutting (reason why i picked spirl down cut)
[05:45:45] <XXCoder> I think it has trough tool coolant spray? it has hole.
[05:47:36] <XXCoder> lemme show one pic though
[05:47:39] <XXCoder> weird one
[05:48:28] <archivist> feel your machine more to detect stress
[05:48:40] <XXCoder> yeah
[05:48:51] <XXCoder> I was holding gantry to stabilize camera, and to feel that
[05:48:52] <SpeedEvil> peck I think would have done better - in that it can push the tool into the work harder and gives time for the tool to cool
[05:49:04] <XXCoder> http://picpaste.com/pics/IMG_20160611_220355-PMWqhDZY.1465726933.jpg
[05:49:21] <XXCoder> radioactive nylon lol
[05:49:35] <XXCoder> you can see the tool, still stuck on it.
[05:50:29] <XXCoder> http://picpaste.com/pics/IMG_20160611_220635-mQYwCLhm.1465727013.jpg melty fun
[05:50:51] <XXCoder> SpeedEvil: ok, might try that later, if I want better gage holder
[05:51:04] <archivist> that material stuck on the tool stops new chips travelling up the flutes, use a longer endmill on deep crap
[05:51:09] <XXCoder> ior work with nylon again (I do still have hmm 15? of those left.
[05:51:36] <XXCoder> I think as it got stuck it heated up and nylon loves to fuse when hot
[05:51:49] <archivist> stop mid job to clean up as well
[05:52:04] <XXCoder> I did that but I need to do that more too
[05:52:50] <XXCoder> mostly cleaned, tool finally extracted
[05:52:51] <XXCoder> http://picpaste.com/pics/IMG_20160612_010421-eBLCy49u.1465727154.jpg
[05:53:09] <XXCoder> huge chamfers lol
[05:53:28] <XXCoder> once I get my noma deburr tool I plan to try even it up a little
[05:53:39] <XXCoder> too bad it didnt finish bottom right
[05:53:42] <XXCoder> er left
[05:57:23] <__rob> wouldn't some coolant help on that nylon ?
[05:57:26] <__rob> and slower rpm
[05:57:58] <XXCoder> __rob: yep... and yep
[05:58:09] <XXCoder> my machine is still very crude
[05:58:18] <__rob> looks like its melting on
[05:58:25] <XXCoder> keep watching
[05:58:26] <__rob> onto the endmill
[05:58:45] <__rob> ohh dear
[05:58:55] <XXCoder> yeah
[05:58:59] <__rob> you just want chunky chips that are cold
[05:59:02] <__rob> I reckon
[05:59:07] <XXCoder> yeah been avised on it
[05:59:21] <XXCoder> I just felt like running something, I got tired of doing nothing with machine lol
[05:59:22] <SpeedEvil> Is sticking the nylon in the freezer a useless idea, or might it sometimes worik?
[05:59:22] <__rob> ohh, yea, not read through the above, just the video
[05:59:26] <SpeedEvil> 40C colder, ...
[05:59:46] <__rob> SpeedEvil, surely will just head up around the end mill stragith away
[06:00:04] <XXCoder> __rob: ironically Y axis "broke". I guess last time I tested it with steppers and stuff tuneup it loosened up one of coupler bolts
[06:00:29] <__rob> I've only really done abs as far as plastics
[06:00:34] <__rob> but that is great with slow rpm
[06:00:36] <__rob> and coolant
[06:00:37] <XXCoder> nylon is.. fun
[06:00:48] <__rob> big chips, nice finish
[06:00:57] <XXCoder> at work its easy because program is made by other people, and a shitton of coolant spraying on it
[06:01:17] <XXCoder> in fact I worked on one part, that is why i have lots of nylon pucks lol
[06:01:44] <XXCoder> its prep that just cuts disk out and leaves square slab with hole in it, prep for lathe
[06:01:57] <XXCoder> it makes some thin ring gasket or something
[06:04:01] <__rob> should try that with coolant
[06:04:08] <XXCoder> yeah too bad no coolant
[06:04:09] <__rob> for a cheap solution fish tank pumps work well
[06:04:24] <XXCoder> I was pondering using ac going full blast at ice cold temp as coolant
[06:04:26] <__rob> £15 and a food container
[06:04:38] <XXCoder> my machine isnt waterproof yet
[06:04:57] <__rob> right, but you can limit the flow to the work area
[06:05:21] <__rob> http://www.allpondsolutions.co.uk/aquarium/aquarium-equipment/aquarium-pumps/
[06:05:29] <__rob> had one of these running for about a year without problems
[06:05:33] <XXCoder> yeah, I rather wait till I make actual enclosure for controller and better position pc. pc is under macgine, not good idea when its flowing coolant of some kinf ;)
[06:05:37] <jthornton> XXCoder: are you making a bunch of them or just a couple
[06:05:42] <XXCoder> jthornton: one.
[06:05:55] <XXCoder> might make another one after I understand nylon more
[06:06:04] <XXCoder> or after I add hella coolant system
[06:06:13] <jthornton> cut each hole to a depth of 1/8" then wait to cool then repeat
[06:07:03] <jthornton> and if you can drill the holes first
[06:07:31] <SpeedEvil> Stick a pot of water with ice-cubes in it next to the work, and alternate cutting that with the work
[06:07:36] <XXCoder> more tool changes, it sucks on tool change atm
[06:07:43] <XXCoder> SpeedEvil: thats decent idea
[06:08:43] <XXCoder> though I'd have to turn spindle on and off myself lol
[06:08:48] <XXCoder> thats what sucks about spindle
[06:09:11] <XXCoder> unless just leave it spinning it will spray some
[06:09:19] <jthornton> the nylon is what you want to keep cool by taking shallow cuts and allow time to cool or put some water in the holes
[06:09:52] <XXCoder> one of things I need to do is rewire motors
[06:10:01] <XXCoder> current system works but very not waterproof
[06:10:09] <jthornton> the nylon does not cool very fast like a metal would
[06:10:17] <XXCoder> I also want nice easy disconnect/connect connectors
[06:10:30] <XXCoder> jthornton: yeah it has more heat capactity.
[06:10:50] <XXCoder> floating iceberg has more heat than hot coffee
[06:10:57] <SpeedEvil> HEat propagates very slow through nylon
[06:11:08] <SpeedEvil> you're only heating the top ~10um or whatever when you cut.
[06:11:22] <XXCoder> SpeedEvil: yeah chips was very hot lol burnt me a little
[06:11:26] <SpeedEvil> Unless you start making a liquid layer which rapidly stirs heat efficiently in
[06:11:34] <XXCoder> at slower rpm part it wasnbt bad
[06:11:47] <XXCoder> later ow, more heat AND it flungs em out more lol
[06:12:44] <SpeedEvil> Once your tool starts getting to melting point of the material, it can be hard not to transition to friction stir machining
[06:14:04] <jthornton> dang found a place to get press brake dies
[06:15:26] <jthornton> http://stores.ebay.com/riteway-brake-dies?_trksid=p2047675.l2563
[06:16:59] <XXCoder> BRAKE DIES!!
[06:17:10] <XXCoder> heh
[06:17:19] <XXCoder> anyway thanks for explains all
[06:17:41] <XXCoder> my next plan is to engrave something on bamboo floor sample
[06:17:49] <XXCoder> any tips on bamboo?
[06:18:58] <XXCoder> __rob: thanks on fountain/fish pump tip, will check into it when machine more waterproof and well placed. :)
[06:19:01] <jthornton> https://www.onsrud.com/
[06:19:58] <jthornton> https://www.onsrud.com/plusdocs/Doc/index.html?model.code=wood
[06:20:32] <archivist> their standards are so high they cannot speeel standard "Our dies are made with the latest of modern equipment to stardards higher than...read more"
[06:20:50] <XXCoder> wow higher than rwead more
[06:20:51] <jthornton> lol
[06:20:59] <XXCoder> amazing. its hard to beat read more
[06:21:11] <XXCoder> them tools is expensive lol
[06:21:22] <XXCoder> used to shitty tool prices I guess
[06:22:00] <XXCoder> I rather break $5 tool (I broke one today) than $35 one
[06:28:52] <jthornton> I'd rather use a $35 tool and not break it lol
[06:29:01] <XXCoder> indeed
[06:29:05] <XXCoder> not at that stage yet
[06:29:15] * jthornton goes back to debian file sharing 0.001
[06:29:33] <XXCoder> april 24 2014 was day i got my first cnc part. lol
[06:29:42] <XXCoder> cnc electrics incluyding tb6560
[06:29:50] <XXCoder> geez. 2 years now
[06:30:11] <XXCoder> first year was very slow (and wasted since I dont use half of parts :)
[06:37:06] <jthornton> hot damn I finally guessed enough times to share files from debian!
[06:38:42] <XXCoder> oh yeah
[06:39:06] <XXCoder> SpeedEvil: about adding delays I remember one job that required me to polish part before removing it by cutoff
[06:39:51] <XXCoder> programmer was smart, guy added very slow tool movement, I guess .001 ipm or something for half minute so I can hit pause and it will leave part spinning
[07:01:39] <rene-dev> PCW Im looking for an easy way of inverting the smartserial tx pin in hostmot
[07:02:23] <rene-dev> PCW I tried inverting iobits in the top module
[07:27:43] <jthornton> http://gnipsel.com/images/press-brake/Press%20Brake%20Base.JPG
[07:44:56] <archivist> jthornton, I want one but....small
[07:47:11] <jthornton> small is good too, I'm making this one to fit my 50 ton press which is 35" wide on the inside so a 34" wide press brake with 30" dies
[07:48:53] <archivist> heh kit on ebay http://www.ebay.co.uk/itm/SWAG-12-TON-Press-Brake-DIY-Builder-Kit-/252393136173
[07:52:06] <jthornton> I have one similar to that but 26" wide and no repeatability
[07:52:47] <jthornton> I'm getting real dies and punches and making the rest
[07:54:31] <archivist> so far been using a vice for my tinware bending
[07:58:35] <pcw_home> rene-dev: not sure if doing it in hal is too late
[07:58:37] <pcw_home> Why do you need to invert the polarity?
[07:59:00] <jthornton> I have a brake a gentleman made for radio enclosures, very neat
[08:05:08] <Magnifikus> so "if" i use can open servos with interpolated positions, is it viable to reduce the cycle time of the RT to 100Hz?
[08:05:11] <Magnifikus> cause The control system must not transmit PDOs more often than every 4 ms,
[08:05:57] <Magnifikus> i dont really see a problem with that update rate but not sure about circles for example
[08:06:06] <archivist> "open servo" that sounds like an oxymoron
[08:06:18] <Magnifikus> nah can open
[08:06:44] <jthornton> http://gnipsel.com/images/press-brake/Press%20Brake.JPG
[08:06:53] <jthornton> just need to figure out back stop and down stop
[08:08:28] <zeeshan> will you use that in your hyd press
[08:08:41] <Tom_itx> when it can't go no mo it will stop
[08:08:44] <rene-dev> pcw_home not in hal, in vhdl
[08:09:27] <rene-dev> pcw_home I need to invert it because I made a board with wrong diff pairs
[08:31:22] <jthornton> might need to do a reload to see the updated one http://gnipsel.com/images/press-brake/Press%20Brake.JPG
[08:31:30] <jthornton> back gauge added
[08:33:04] <jthornton> thinking of an over the top down stop
[08:42:47] <jthornton> refresh and see down stops
[08:45:29] <Jymmm> jthornton: https://www.youtube.com/watch?v=mn1GsAJcpok
[08:49:12] <jthornton> saw that it's a junk brake
[08:49:35] <jthornton> I have a crappy one now...
[09:02:44] <pcw_home> rene-dev: if this is just a temporary hack I would just add it to the sserial pin assignment section of hostmot2.vhd
[09:44:30] <Polymorphism> Build went.... ok so far.
[09:44:34] <Polymorphism> Ran into some problems last night
[09:44:38] <Polymorphism> had to call it at midnight
[09:44:43] <Polymorphism> going to attack the problem again today
[09:44:53] <rene-dev> pcw_home problem is im using a 7i76e, and need the builtin slave to work
[09:45:07] <rene-dev> pcw_home so I cant just invert all the tx pins
[09:46:01] <Polymorphism> couldnt get the bearing pressed onto 1605 ballscrew, then accidentally freed some of the balls while messing around with it. So now I get to reassemble the ballnut//screw somehow. Then I can go back to dealing with the bearing issue
[09:46:29] <Polymorphism> it is starting to take form even with this setback
[09:51:14] <JT-Shop> I need to rethink my plasma touch off stratigity
[09:51:25] <JT-Shop> strategy
[09:55:25] <Polymorphism> so irritating
[09:55:35] <Polymorphism> Shouldnt have to buy a 200 dollar press to put this bearing on
[09:55:41] <Polymorphism> yet here I am, about to leave for harbor freight
[09:55:58] <SpeedEvil> hammer
[09:56:16] <archivist> threaded rod and plates
[09:56:33] <zeeshan> hammer works :P
[09:57:09] <archivist> hammer gets stuff out of line and even tighter :)
[09:57:16] <zeeshan> start it square :P
[09:57:31] <archivist> then it gets out of square
[09:57:45] <archivist> rounded edges
[09:58:10] <zeeshan> man
[09:58:14] <zeeshan> im sitting on my ass watching amovie
[09:58:23] <zeeshan> and the fixture and cnc mill are doing its job
[09:58:32] <zeeshan> took forever to get to this point, but its all perfectly tuned now :D
[09:58:41] <SpeedEvil> Get a hydraulic press, and make the money back from youtube views.
[09:58:47] <zeeshan> SpeedEvil: ROFL
[09:59:25] <archivist> I should have added ads to one of mine that got to 600k views
[09:59:33] <zeeshan> which one archivist
[09:59:36] <zeeshan> thats a lot of views!
[10:01:24] <archivist> https://www.youtube.com/watch?v=HAtziCsUj5Q
[10:01:41] <zeeshan> very nice!
[10:02:44] <_abc_> Hello. What's the root / su password set to in the linuxcnc live wheezy iso?
[10:02:47] <_abc_> It is not 'live'
[10:03:41] <JT-Shop> you set the password when you install
[10:03:49] <JT-Shop> what are you trying to do?
[10:05:44] <_abc_> I never said 'install'
[10:06:00] <_abc_> I have graphics problems with the iso and am trying to fix it from console.
[10:06:04] <_abc_> Module snafu.
[10:06:14] <_abc_> I read somwhere 'sudo passwd root' should work. Does it?
[10:07:26] <_abc_> Plain sudo with empty pwd does not work
[10:08:36] <archivist> sudo name
[10:08:48] <archivist> then password at the prompt
[10:09:25] <Polymorphism> SpeedEvil, lol
[10:10:24] <Polymorphism> cool vid archivist
[10:11:13] <_abc_> what name? ;)
[10:11:53] <Duc_mobile> Polymorphism: hows the building going
[10:12:50] <Polymorphism> Duc_mobile, so-so. The lower frame///gantry sides+ back are together. Ran into some issues with the ballscrews though. Couldnt get the bearing to go on for y axis, maybe z. Then accidentally freed some of the balls messing around with it
[10:13:13] <Polymorphism> so today my project is to reassemble the 1605 ballscrew following youtube videos of similar but different screws
[10:13:19] <Polymorphism> then I'm back to figuring out how to get the bearings on
[10:13:34] <Polymorphism> may just purchase a press as they want 30 per bearing at my local shop
[10:13:48] <Polymorphism> another builder of the machine said he sanded the shaft a bit, but that seems... wrong? I don't knoiw
[10:13:51] <Polymorphism> maybe thats what I need to do
[10:14:15] <Polymorphism> once I get beyond this issue I can finish the machine in a few more hours, then its the electronics
[10:17:06] <yasnak> http://wfla.com/watch-us-live/
[10:17:11] <Duc_mobile> dead blow hammer and taking your time sometimes works
[10:17:17] <yasnak> 50 dead, 53 injured
[10:19:29] <Polymorphism> I hope I didnt ruin the ballnut
[10:19:40] <Polymorphism> got a bad feeling those balls never will go back, plus I just read this "As a minor warning, some ballscrews with the zero backlash option (preloaded balls) alternate two sizes of balls to make it run smoother. So one ball is 2mm, the next 2.005mm, the next 2mm etc. It acts like a cage pushing the bigger balls into the loaded zone with less friction.
[10:19:40] <Polymorphism> So removing all the balls and putting them back after a cleaning will not always make the screw as good as new"
[10:19:48] <Polymorphism> hope I dont have that type
[10:20:39] <Polymorphism> yasnak, http://2ndrun.tv/news_directory/national/cnn/ all the free news
[10:20:46] <Polymorphism> or should I say all the news free =D
[10:21:04] <Polymorphism> actual live stream from the sat no paywall or limited preview crap
[10:21:46] <Polymorphism> Duc_mobile, I'll try that first. I do have a deadblow
[10:22:18] <yasnak> weird
[10:22:37] <yasnak> site says YOUR IP ADDRESS: MY VPN & Has Been Logged
[10:22:40] <yasnak> doesn't show anything
[10:24:03] * JT-Shop has no idea what _abc_ is talking about
[10:24:29] <JT-Shop> so I think my setting G92 Z in my touch off is screwing me up
[10:32:32] <Polymorphism> sounds like it might be RIT
[10:56:25] <_abc_> 50 dead?!
[10:56:54] <_methods> high score
[10:56:59] <Polymorphism> Trump 2016
[10:57:34] <Polymorphism> this is radical islamic terrorism
[10:57:54] <_methods> they need to make grenade launchers legal now so it's easier to get that high score
[10:58:37] <Polymorphism> https://throwflame.com/
[10:58:40] <Polymorphism> how about a flamethrower?
[10:58:54] <Polymorphism> already legal =D
[11:02:31] <_abc_> Wow how could a single person achieve that score. Nobody jumped him?
[11:04:38] <Polymorphism> lets not call it a score, thats in really poor taste
[11:04:43] <Polymorphism> but yes, people are cowards
[11:04:49] <Polymorphism> and either run or watch it happen
[11:05:42] <Polymorphism> on a lighter note, I could really use a ballscrew expert right now. I fucked up the ballnut on my 1605 by unscewing it too far and some balls fell out. Can I put these back in? are they all the same size? do I need a new ballnut...
[11:06:03] <malcom2073> Polymorphism: Yes you can put them back in, be sure they're clean with no grit in them
[11:06:22] <malcom2073> If they fell on the floor, you should clean them with alcohol and regrease once they're back in
[11:06:34] <Duc_mobile> _abs_: most people are programeed to run from that sound and not even sure I would run towards it. thats a unique person
[11:06:38] <Polymorphism> not onto floor just out of the interal tracks and it wont spin now
[11:06:56] <Polymorphism> so I think it needs to come all the way off maybe
[11:07:03] <Polymorphism> unless I can feed them back in somnehow
[11:07:06] <malcom2073> Is this a preloaded nut?
[11:07:11] <Polymorphism> I'm not sure =\
[11:07:16] <malcom2073> Find out
[11:07:22] <Polymorphism> k
[11:07:37] <Polymorphism> http://g03.a.alicdn.com/kf/HTB1AJunIVXXXXbTXFXXq6xXFXXXe/TBI-1605-C7-1150mm-ball-screw-5mm-lead-with-SFU1605-ballnut-of-BK12-BF12-set-end.jpg
[11:07:39] <Polymorphism> it looks like that
[11:07:48] <malcom2073> That tells nothing though
[11:07:51] <Polymorphism> ok
[11:07:53] <Polymorphism> I was afraid of that
[11:07:56] <malcom2073> You can't tell byl ooking at it, the mfg spec sheet should tell you
[11:08:04] <malcom2073> If its a cheapchinese one: Probably not
[11:08:10] <malcom2073> In which case, clean, reload, and go
[11:08:16] <Polymorphism> I paid extra for it, so I hope its not too cheap
[11:08:27] <Polymorphism> I'll ask george
[11:08:38] <Roguish> Poly: yes, you can put the balls back into the ballnut. just be clean and careful,'
[11:08:49] <malcom2073> It would've specified, since preloaded screws cost more
[11:09:52] <Polymorphism> I asked george, I;ll know later today
[11:10:20] <Polymorphism> some missing parts also. c clips and nuts. George is shipping them out tomorrow, so customer service is good so far
[11:10:36] <Roguish> Poly: that does not look at all like a pre-loaded nut screw.
[11:10:51] <Polymorphism> ok
[11:11:07] <Polymorphism> can I feed them back in without taking the nut off of the screw?
[11:11:14] <Polymorphism> or does it need to come totally apart now
[11:11:24] <Polymorphism> I was trying to answer this with youtube but they seem to be different scews
[11:11:35] <malcom2073> Right, there's a wide variety of designs
[11:11:38] <Roguish> ya can't hurt it by trying.
[11:11:42] <malcom2073> Don't force it
[11:11:47] <Roguish> Don
[11:11:52] <Polymorphism> ok
[11:12:06] <Roguish> Don't force it. like malcom2073 said.
[11:12:26] <Polymorphism> I'll take a look after lunch
[11:13:36] <Polymorphism> One other thing, attaching the linear rails to the profiles required leveling them at both ends and center. I got it within .1mm on both sides but I don't know if thats good enough
[11:13:48] <Polymorphism> I would want to go back and make it right now before I go any further with the build if thats an issue
[11:13:55] <Polymorphism> although I'm not sure how I would get it much better
[11:14:00] <Polymorphism> all the other rails have ledges to sit on
[11:14:08] <Polymorphism> so its just this axis thats an issue
[11:14:52] <Polymorphism> the long one
[11:14:56] <Polymorphism> not sure if thats called X or Y
[11:15:14] <Polymorphism> http://forums.azbilliards.com/attachment.php?attachmentid=407949&stc=1&d=1452266839
[11:15:18] <Polymorphism> as seen in this pic, side rail
[11:15:35] <Roguish> Poly: it all depends on what your goal is for the entire project. .1mm = .004 in. not too bad considering you are using extruded structure.
[11:16:41] <Roguish> if you are trying to get sub-micron accuracy, you will not make it. be realistic.
[11:18:15] <Roguish> how do you plan on getting the two side rails parallel? what is your accuracy target for parallelism?
[11:18:25] <Polymorphism> I have no idea, its very upsetting actually
[11:18:31] <Polymorphism> because this wasnt mentioned prior to spending all this money
[11:18:37] <Polymorphism> he said it just bolts together and I only need a ruler
[11:18:41] <Polymorphism> I consider that a lie at this point
[11:18:45] <malcom2073> Nah it's nota lie
[11:18:55] <Polymorphism> the other two axis the rail presses against a ledge
[11:18:55] <malcom2073> If you don't care much about accuracy, you can bolt it together and it should work
[11:18:59] <Roguish> what's it going to be used for?
[11:19:22] <Polymorphism> routing control panels and cutting PCBS for LQFP .4mm pitch
[11:19:27] <Polymorphism> also hardwood carving
[11:21:06] <Polymorphism> it was quite difficult even with me and a friend leveling those rails... I'm not sure how to get them better or parallel to both sides without a special method or tool
[11:21:18] <Roguish> the word working probably doesn't need to high an accuracy. if the pcb's are small, it's still probably ok, because the accuracy over a small distance is much better that over the full length.
[11:22:32] <Roguish> generally, one fixes one rail, with the other still 'loose', then moves a fixture with blocks on it along and tightens the loose rail as you go.
[11:23:30] <Polymorphism> ah I see how that would ensure they are fairly paralellel once one side is leveled
[11:24:26] <Roguish> same issue with the ball screw. it should be 'parallel' to the rails.
[11:26:01] <Roguish> it they rails and screw aren't parallel, they will bind. if the assembly runs back and forth freely without noticable binding, then they are parallel.
[11:26:15] <Polymorphism> it slides back and forth free right now
[11:26:23] <archivist> get a machinists level
[11:26:58] <archivist> and a machinists square
[11:27:31] * Polymorphism googles
[11:28:54] <roycroft> you can probably get the long rails parallel within about 0.100" almost by eye, and certainly with a ruler
[11:29:10] <archivist> and read a few resources on machine measurement to get better
[11:29:11] <roycroft> over 48" that's only 0.002" per inch
[11:29:28] <Roguish> a good square will help in aligning (squaring) the other 2 axes. but bring those in best by tramming, I think.
[11:30:20] <Polymorphism> he claimed I wouldnt need to do any of that
[11:30:32] <Roguish> the initial setup of the long axis rails establishes the basic plane to work everything else from.
[11:30:35] <Polymorphism> ":NO need to square machine. Every part is pocketed , pined or has ledge to sit on leaving machine square without need of any gauges"
[11:30:39] <archivist> I have started a web page on measuring ones machine, very incomplete so far http://www.archivist.info/cnc/machine_measurement/
[11:30:54] <archivist> rofl
[11:30:59] <Polymorphism> guess that statement is a lie
[11:31:03] <Polymorphism> I will be noting this in my forum review
[11:31:13] <Polymorphism> hundreds of dollars of extra tools required, etc
[11:31:21] <Polymorphism> I feel very misled
[11:31:29] <Polymorphism> but nothing I can do now but press forward
[11:31:46] <archivist> well depends if assembile their way is within spec they give
[11:32:12] <Roguish> hang on Poly. bear in mind what the purpose of the machine is for.
[11:32:12] <roycroft> you won't need hundreds of dollars of extra tools
[11:32:16] <Polymorphism> I used a caliper with depth guage against the top of the profile to try to level the rails
[11:32:20] <Roguish> archivist: exactly.
[11:32:42] <roycroft> and i would suggest you focus on getting the thing dialed in, and not on leaving negative reviews
[11:32:44] <archivist> I used to work for a kit supplier, I do know the variable ability of the kit assemblers :)
[11:32:49] <roycroft> get it working first, then see how you feel
[11:33:00] <Polymorphism> k
[11:33:22] <Polymorphism> I probably have to take the gantry sides and back off again if I'm going back to try to level those rails better
[11:33:46] <Polymorphism> but I'm not sure how I would do that
[11:34:06] <Polymorphism> I had a freidn hold the rail and tap it gently to adjust while I tightened
[11:34:10] <Roguish> in the linear motion business, it's called 'installed straightness'
[11:34:11] <Polymorphism> using caliper depth guage along the rail
[11:34:14] <Tom_itx> the accuracy is in your hands
[11:34:20] <Tom_itx> pass or fail
[11:34:25] <Polymorphism> well that sucks
[11:34:26] <Polymorphism> its bad design
[11:34:32] <Polymorphism> hhis new model has a ledge for this rail too
[11:34:33] <Roguish> what's stiffer? the rails or the frame? which one forms to the other?
[11:34:50] <Polymorphism> the frame is stiffer I think
[11:34:56] <Roguish> it's not a bad design, it's an inexpensive design.
[11:35:13] <Tom_itx> bad understanding of the design
[11:35:31] <Polymorphism> I feel like I'm going to end up with less accuracy than if I'd just bought a 6040
[11:35:34] <Polymorphism> and THAT is worrisome
[11:35:40] <Polymorphism> as I spent 3x more
[11:35:45] <Polymorphism> so I need to get as much out of this as I can
[11:35:57] <Tom_itx> spend some more yet
[11:36:00] <Tom_itx> that will fix it all
[11:36:03] <Roguish> what's a 6040? got a link?
[11:36:16] <Polymorphism> Roguish, http://www.ebay.com/itm/CNC-Router-Engraver-Milling-Machine-3D-Engraving-Cutting-4-Axis-6040-Desktop-/121937895581
[11:36:26] <Jean__> hello group; somebody speak in french for help I am a new user ( in pv please) ??
[11:36:28] <Tom_itx> or take what you have and work with it to make it what you want
[11:37:44] <Roguish> same issues with the 6040. 1st problem is they're all aluminum. 1/3 the stiffness of steel for the same geometry, and thermally crappy.
[11:37:49] <Tom_itx> btw poly, what did you buy?
[11:37:59] <Polymorphism> http://www.xzerocnc.com/raptor.htm
[11:38:02] <Polymorphism> the small version of this
[11:38:19] <Polymorphism> 12.5x30"x5" work area
[11:38:38] <Polymorphism> and there is no going back now
[11:38:40] * Polymorphism feels sick
[11:38:47] <Polymorphism> have to stay positive now. Have to make this work
[11:38:47] <Roguish> Tom_itx is correct. assemble it carefully and use it.
[11:38:59] <Tom_itx> i'm not wild on gantry design anyway
[11:39:33] <Polymorphism> I will attempt to do so
[11:39:37] <Polymorphism> the other rails are easy
[11:39:45] <Polymorphism> I just held them tight againt the ledge and tightened down
[11:39:56] <Polymorphism> so on these long rails I need a machinists level?
[11:40:02] <Polymorphism> level the frame, then use the machinists level on the rail?
[11:40:23] <Polymorphism> or are you suggessting that off by about .15mm is "ok"
[11:40:24] <Tom_itx> or a dial indicator on a granite plate
[11:40:36] <Polymorphism> I have a clamping dial indicator
[11:40:38] <Polymorphism> I just purchased
[11:40:45] <Polymorphism> but wasn't sure how it would help with this
[11:40:49] <Polymorphism> and I have no granite plate
[11:41:31] <roycroft> is the problem that the bed is uneven?
[11:42:05] * _abc_ set up 2 diy machines using only a machinist's right angle squre/ruler for pcb engraving and simple case work, and both have been working for a long long time.
[11:42:06] <Tom_itx> http://www.judgetool.com/series570digitalheightgage-1.aspx?gclid=CMP3xJvxos0CFQ6naQodu7gN-w
[11:42:11] <Tom_itx> on a granite plate
[11:42:59] <_abc_> Overkill in setting up the machine is easily achieved. Hobby machines have runouts and other problems which are not fixable by using better measuring gear.
[11:43:41] <roycroft> i don't know what software you're using, but i know the routed pcb folks run some code that essentially generates a topo map of the bed so they can compensate for irregularities
[11:44:03] <Polymorphism> yeah Z probing
[11:44:06] <Polymorphism> I was going to do that for my PCBs
[11:44:06] <_abc_> Yes I implemented that too, manually, but am not using it, it is okay without
[11:44:30] <_abc_> The small machine does 120x170mm iirc
[11:44:38] <_abc_> no need to correct over that.
[11:44:59] <Polymorphism> so the more of the work area I want to use the more critical the leveling is
[11:45:07] <Polymorphism> as the error across a small area is very small
[11:45:12] <_abc_> http://www.reuters.com/article/us-tesla-safety-idUSKCN0YW2CF more usa nda/weird agreements.
[11:45:14] <roycroft> correct
[11:45:29] <_abc_> Yes, area/linear travel is important
[11:45:46] <Tom_itx> measure an arc at 1" and measure it at a mile and notice the difference
[11:46:16] <Tom_itx> it may appear straight at 1"
[11:47:01] <Tom_itx> ^^ over exageration
[11:47:07] <Tom_itx> for a point
[11:47:32] <_abc_> Most hobby machines will be up to 210x297mm or so work area, that's an A4 sheet size, relatively easy to keep straight and to level using one pass of levelling milling. I skipped that *too*.
[11:47:37] <roycroft> assuming you will be moutning this thing on a stand and it will never move once mounted, you can level it with the spindle as well
[11:48:10] <roycroft> _abc_: pcbs need to be routed to a precise depth
[11:48:16] <_abc_> And yes I will never make a MDF machine again. Fwiw.
[11:48:19] <roycroft> they're actually quite particular about that
[11:48:24] <_abc_> roycroft: I noticed ;)
[11:48:37] <Jean__> someone to know sudoers file error?
[11:48:39] <roycroft> wood carving, engraving, etc. not so much
[11:48:49] <_abc_> But one can relatively easily make the bed flat and straight to 0.05mm over 210x297 or so
[11:49:09] <_abc_> Wooden machines always change by themselves. Humidity, strain, etc.
[11:49:29] <_abc_> The wooden machine I made had to be tightened on the frame machine screws every day, before use.
[11:49:39] <_abc_> Will not happen again.
[11:49:45] <Tom_itx> heh
[11:49:53] <roycroft> those aluminium extrusions will move every time you pick them up though, so you really need to mount the thing on a permanent stand if you're going to make it really flat
[11:50:16] <Polymorphism> _abc_, this bed is 300x760mm
[11:50:41] <_abc_> Okay so you have a little more work to do. As roycroft said, aluminum is not the most rigid material around
[11:51:34] <roycroft> you can go to the 80/20 website and look up how much sag per foot unsupported extrusions have
[11:52:12] <_abc_> And 50um sag on 760mm span is very possible.
[11:53:00] <Polymorphism> thats still .05mm
[11:53:05] <Polymorphism> I couldnt get it better than .15mm
[11:53:11] <Polymorphism> and unsure of parallelism
[11:53:13] <_abc_> Yes, twice as thick as the copper on a pcb...
[11:53:22] <_abc_> (more than)
[11:56:35] <_abc_> 10 days till the brexit vote. Am curious how it will work out.
[11:57:53] <roycroft> polling is pretty close
[11:58:05] <roycroft> cameron is in desperation mode
[11:58:08] <_abc_> http://nypost.com/2016/05/30/brexit-vote-is-britains-chance-to-declare-indepenence/ ... a view from afar.
[11:58:31] <roycroft> he's going around saying brexit will mean another indyref
[11:59:15] <_abc_> I guess with all the love he enjoys, his best bet to make people vote 'stay in' would be to *advocate* exit...
[11:59:27] * _abc_ is not a brit btw
[12:00:16] <_abc_> Anyway we want this hurdle behind us, it sends all sorts of shockwaves into the currency exchange rates and other things.
[12:00:27] * _abc_ we the non brits in eu
[12:03:27] <roycroft> i'm not a brit either
[12:03:50] <roycroft> boris will likely be the next pm
[12:04:08] <roycroft> an boris is on a uk-wide get-us-the-hell-out tour
[12:06:04] <Polymorphism> Getting some help from george
[12:06:11] <Polymorphism> ~30 mins replies on a sunday, not bad.
[12:06:49] <Polymorphism> I'm not going to leave a bad review, but I do feel I should mention anything left out or special tools or methods required. To help others in the future
[12:07:45] <Tom_itx> you want the accuracy of a $250k machine that costs 1.4k
[12:07:57] <Tom_itx> not gonna happen
[12:08:36] <Polymorphism> I've actually sunk over 3 grand into this now, its kind of insane
[12:08:54] <Polymorphism> I just want the most accuracy I can reasonably get, so I don't have to rebuild it later
[12:08:55] <Tom_itx> that's peanuts in the cnc world
[12:09:06] <Tom_itx> a small tooling package for a cnc would cost that much
[12:09:46] <Polymorphism> that may be true, this is a large expense for my business at this point though
[12:10:08] <roycroft> take a deep breath, polymorphism
[12:10:15] <roycroft> you can make it work well
[12:10:29] <roycroft> there are a lot of folks here who have heaps of experience with cnc machinery
[12:10:36] <Tom_itx> i agree but just realize what you have
[12:10:52] <Polymorphism> ok
[12:10:58] <roycroft> there's probably 1000 years worth of machining experience ion this channel
[12:11:10] <_methods> that put him on ignore
[12:11:18] <_abc_> $3k is the price of a 3.5 axis Chinese mill, with 2kW water cooled spindle and up to 600x800x60mm work volume. Nothing to see here.
[12:11:29] <Duc_mobile> and you balked at my price for the router table
[12:11:30] <Duc_mobile> stuff adds up quick
[12:11:37] <_abc_> Delivered and set up too, those 3k
[12:11:45] <Tom_itx> _methods problems?
[12:11:54] <_methods> me?
[12:11:58] <Polymorphism> I think I'm going to take a break from this for a bit, worked till midnight last night and all morning today researching
[12:12:07] <_methods> no roycroft said there was 1000 years of cnc experience in here
[12:12:08] <Polymorphism> maybe a clear head will be better when I come back to it
[12:12:22] <_methods> and i said yeah 1000 years of experience that put that moron on ignore
[12:12:23] <roycroft> no, i said there's 1000 years of machining experience here
[12:12:27] <_abc_> _methods: it's probably true.
[12:12:48] <_abc_> Hey let's agree that we agree.
[12:12:48] <Polymorphism> _methods, still trolling after all this time
[12:12:51] <Polymorphism> no surprise there
[12:13:25] <Tom_itx> i fear the build will be as painful as the buy
[12:13:40] <_abc_> It's okay, everyone has to start somewhere and learn.
[12:13:52] <_abc_> It's the bit**ing that is unpleasant to bear out.
[12:14:03] <Duc_mobile> could always be worse
[12:14:27] <Polymorphism> Tom_itx, I could have had all the mechanical parts together in one night if it werent for the leveling + ballscrew bearing issue
[12:14:38] <Polymorphism> once I solve that I expect to have it built in one more night
[12:14:58] <Polymorphism> The electronics will be easier, that's what I'm more used to working with
[12:15:00] <Duc_mobile> at times its good to have two projects so breaks can be taken
[12:15:17] <_abc_> Yes, split the mistakes evenly over several projects ;)
[12:15:21] <Polymorphism> xD
[12:15:46] <_abc_> Taking breaks is important, I do that when I get stuck, move on to chores or something else. When back, the OBVIOUS is always staring me in the face. Almost always.
[12:15:59] <Duc_mobile> _abc_: also give time to clear the mind
[12:16:04] <_abc_> Working with a "twin" as a team is a win, but very few people have that luxury.
[12:16:30] <Duc_mobile> thats why I play with the wifes cat when Im pissed
[12:19:57] <Jean__> I'm lookin for cnc verital table 4 x 8 (built your cnc) you have a recommandation?
[12:20:37] <_abc_> 4 x 8 what? Meters? Inches?
[12:20:53] <Duc_mobile> guessing feet
[12:20:55] <Jean__> feet
[12:21:14] <_abc_> 4 x 8 x ??
[12:21:40] <Duc_mobile> thats a pretty good size. for a router or real mill
[12:21:47] <Jean__> 16 inch elevation
[12:21:54] <_abc_> About a twin you can work with, to find his bugs so he can find yours: http://www.theregister.co.uk/2016/04/12/pair_programming_the_most_extreme_xp_practice/
[12:22:38] <_abc_> I don't think there are Chinese mills that big but I may be wrong.
[12:22:55] <malcom2073> Pair programming is an awesoem thing, and very hard to find
[12:22:59] <_abc_> Also Jean__ needs to spec for what. Steel/general machining, wood/plastic etc
[12:23:00] <Jean__> from texas, builtyourcnc
[12:23:41] <Jean__> https://buildyourcnc.com/item/cnc-machine-greenLean-v1
[12:23:43] <_abc_> malcom2073: One assumes in a consultant life one can 'pair' up with some other consultant and get things done like that. Associated or not, local or remote...
[12:24:35] <_abc_> That website does not play well with my browser
[12:24:37] <mase-tech> Polymorphism: link to your blog plz
[12:24:46] <malcom2073> _abc_: I've done that before, it's much better when you're equals, which as consultants you never are
[12:25:03] <_abc_> malcom2073: True. A remote one can help like that.
[12:25:07] <Jean__> but before to buy I want ton use on demo mode linuxcnc with cambam and other application and I have a lot of bugs
[12:25:18] <Duc_mobile> that would be nice. Hell just a helper
[12:25:38] <_abc_> That is a 100% wooden machine Jean__ ?
[12:25:41] <Polymorphism> mase-tech, I have pictures but no blog yet, I will post them up soon
[12:25:54] <Jean__> yes wooden
[12:26:16] <Polymorphism> wow those are some big prices
[12:26:33] <Jean__> local is on atmosphere egal 20 C, humidty 60%
[12:26:39] <_abc_> Jean__: you need to process only wood and plastic right?
[12:27:00] <_abc_> And not very precise.
[12:27:12] <Jean__> wood I am a woodworker
[12:27:16] <_abc_> ok
[12:27:35] * _abc_ has some choice words to web designers who build sites like that
[12:28:04] <Jean__> but who run linuxcnc ?
[12:28:21] <_abc_> 16 in tall volume means you can put in a complete coffee table in there I think. And a lot of decent sized sculptures, lying on a side.
[12:34:53] <Duc_mobile> Im not to big of a fan of machines made out of wood
[12:38:52] <SpeedEvil> Various interesting treatments drastically reduce the movement of wood with humidity
[12:39:33] <SpeedEvil> Simply heating in atmospheric steam to 180C for 1h or so dramatically reduces movements.
[12:39:48] <Jean__> when we control the athmospher, wood is stable fix dimension
[12:40:30] <SpeedEvil> It's irrelevant as long as you'vbe done the sums and made sure it's OK for your app
[12:40:52] <SpeedEvil> Cast iron is great, and you can even put it in a woodstove and it'll come out exactly the same shape.
[12:41:05] <SpeedEvil> It is rather harder to manufacture, and slightly heavier though
[12:42:08] <Jean__> a lot pf factor can change the precision! other of the casing of the machine!
[12:42:27] <SpeedEvil> Quite.
[12:45:17] <maxcnc> hi from a wet Germany
[12:45:32] <Polymorphism> hi from a cold USA
[12:45:53] <maxcnc> oh the US took another hit today acording to Cnn
[12:46:32] <Polymorphism> the shooting, yeah
[12:46:38] <Polymorphism> they need to legalize concealed carry in clubs, etc
[12:46:38] <maxcnc> Polymorphism: is the mill running
[12:46:48] <Polymorphism> or the owners need to allow it
[12:46:53] <Polymorphism> maxcnc, not yet
[12:46:55] <Polymorphism> I had some problems.
[12:46:59] <maxcnc> more weapons all the usa needs
[12:47:03] <Polymorphism> agreed
[12:47:19] <maxcnc> from kindergarden to coroner service
[12:47:20] <Polymorphism> I had some trouble leveling the side rails, and also the ballscrew bearing wouldnt go on, and then I dropped balls out of it
[12:47:23] <Polymorphism> so now I'm fixing it
[12:47:34] <malcom2073> Need less guns in the hands of nuts, more guns in the hands of good people. you can't have either here though
[12:47:46] <maxcnc> bad behavier
[12:48:42] <maxcnc> Polymorphism: Rule number 5 Ballscrews of mashine only in middle mount
[12:54:33] <Polymorphism> @_@
[12:57:44] <maxcnc> im off Gn8
[13:02:58] <Polymorphism> gn
[13:13:06] <enleth> Polymorphism: do you have a micrometer to measure the ball bearings? Even if the nut you have uses two sizes, a micrometer will easily tell the the difference.
[13:13:22] <enleth> the hardest part might be popping the return channel cover off
[13:13:46] <Polymorphism> I don't =\ I almost picked one up
[13:14:00] <Polymorphism> only got the dial indicator though, and a simple level
[13:15:05] <enleth> a micrometer can be many decades old and still in perfect working condition so don't be afraid to look for used ones on ebay
[13:15:48] <Polymorphism> ok, will do
[13:16:15] <enleth> (actually even a misaligned one will be capable of sorting ball bearings - it should still be repeatable even if the reading's off)
[13:16:27] <archivist> my best micrometers are all old ones
[13:38:15] <pink_vampire> hi
[13:38:34] <Deejay> hi
[13:40:04] <Polymorphism> http://2ndrun.tv/news_directory/national/cnn/hi
[13:40:33] <pink_vampire> hi Deejay
[13:45:12] <Polymorphism> fdb
[13:47:37] <Deejay> i agree
[13:50:16] <Polymorphism> fdm printer vs sla.. hm
[13:50:17] <pink_vampire> did you saw that http://www.cnn.com/2016/06/12/us/orlando-nightclub-shooting/index.html
[13:50:23] <Polymorphism> yes, crazy
[13:50:38] <Polymorphism> he swore allegiance to isis right before the shooting
[13:51:24] <pink_vampire> this is just insane
[13:51:44] <Polymorphism> worst shooting in american history
[13:52:02] <Polymorphism> and most death in one event since 9/11, or something like that
[13:53:43] <pink_vampire> I'm watching the videos, that just crazy.
[13:54:36] <mase-tech> I am sad and pray for the dead INNOCENT people in america
[13:55:49] <zeeshan> yea its nasty
[13:55:52] <zeeshan> i dunno why people do it
[13:56:02] <mase-tech> because they are enemies
[13:56:08] <mase-tech> we are in war
[13:56:12] <zeeshan> so tell them go back to in their own country
[13:56:15] <zeeshan> if they hate usa so much
[13:57:05] <mase-tech> Agree, I am german, we already have to much of them
[13:57:19] <zeeshan> i'm pakistani
[13:57:28] <zeeshan> i'm so far from radical beliefs its not even funny
[13:57:34] <zeeshan> i'd love to join the army and kill some of these pieces of shits
[13:58:01] <gregcnc> when you believe you must kill others in the name of god what will the result be?
[13:58:16] <zeeshan> they think they'll go to heaven
[13:58:22] <zeeshan> no moron that kills people is going to heaven
[13:58:36] <zeeshan> you better have a damn good reason to kill someone. it's not something to take lightly
[13:58:37] <mase-tech> Maybe as pakistani u know that the christian minority of pakistan is afraid of their muslim countrymen
[13:58:50] <zeeshan> mase-tech: yes i know
[13:58:55] <zeeshan> thats why ill never go back to that shit hole
[13:58:55] <mase-tech> they even afraid to marry offical
[13:59:00] <zeeshan> you can pay me a billion dollars
[13:59:02] <zeeshan> i wont go back
[13:59:11] <zeeshan> i love canada
[13:59:14] <Polymorphism> =D
[13:59:15] <zeeshan> best country in the world!
[13:59:23] <Polymorphism> canada is nice
[13:59:31] <zeeshan> i like usa too
[14:08:01] <Polymorphism> my cnc is from canada =D
[14:10:57] <pink_vampire> my cnc is from china but I got it from grizzly PA,
[14:11:41] <zeeshan> Polymorphism: which one
[14:16:17] <Polymorphism> zeeshan, xzero raptor mini
[14:16:31] <zeeshan> cool
[14:53:34] <enleth> huh, original 600mm Mitutoyo calipers for $500
[15:10:51] <JT-Shop> my Ultimate Spyder seat was made in Canada
[15:48:14] <jdh> aren't spyders canadian?
[15:50:15] <Tom_itx> manufactured by Bombardier Recreational Products
[15:50:24] <Tom_itx> french company
[15:50:27] <Tom_itx> i suspect
[15:55:32] <jdh> quebec I thought
[15:56:31] <jdh> they make johnson/evinrude outboards also
[16:11:35] <Deejay> gn8
[16:36:03] <pink_vampire> plastic 3000mm min
[16:36:07] <pink_vampire> soooo fun
[18:04:43] <Frank_10> hi
[18:05:44] <XXCoder> hey
[18:12:29] <andypugh> Quiet night
[18:14:56] <XXCoder> yeah
[18:15:15] <XXCoder> andypugh: did you see video? I played around a little with my cnc machine
[18:15:19] <XXCoder> it wasnt a success
[18:15:24] <XXCoder> but fun anyway
[18:16:00] <andypugh> No, I didn’t see it. Link?
[18:16:12] <XXCoder> sure a sec
[18:16:54] <XXCoder> https://youtu.be/sojJgCfDbp4
[18:17:37] <XXCoder> pictures http://picpaste.com/pics/IMG_20160612_010421-eBLCy49u.1465727154.jpg http://picpaste.com/pics/IMG_20160611_220355-PMWqhDZY.1465726933.jpg http://picpaste.com/IMG_20160611_220635-mQYwCLhm.jpg http://picpaste.com/pics/IMG_20160611_220635-mQYwCLhm.1465727013.jpg
[18:18:41] <andypugh> It’s bizarre, I can’t normally smell a Youtube video :-)
[18:18:54] <XXCoder> lol
[18:19:31] <XXCoder> I still wonder about that real weird glow. I think it acciently acted as retrorefective matter
[18:19:41] <XXCoder> so most light went back to camera
[18:20:02] <andypugh> Lubricant might have helped
[18:20:22] <XXCoder> and many other stuff like coolant yeah
[18:20:38] <XXCoder> had a big discussion in here while ago lol
[18:21:35] <[cube]> i wonder if blowing air on the plastic would help
[18:21:59] <XXCoder> yeah, I was thinking about using AC for super cool air
[18:22:13] <[cube]> i'm running an airline into cnc shed this week
[18:22:18] <[cube]> i'll experiment on some acrylic
[18:22:31] <[cube]> air isnt cool but i think compressor air would be neough
[18:22:41] <XXCoder> AC air not cool? lol
[18:22:46] <XXCoder> AC makes real cold air
[18:22:47] <[cube]> no i mean from my compressor
[18:22:55] <XXCoder> ahh ok lol
[18:22:57] <[cube]> its just ambient temp i guess?
[18:23:00] <[cube]> ac would be a plus
[18:23:18] <[cube]> but i could easily rig up a mount + solenoid on the spindle
[18:23:24] <XXCoder> I still wonder what would happen if I input output from AC into compressor
[18:23:28] <[cube]> to activate air gun
[18:23:58] <[cube]> just bought 10 sheets of 1/4" acrylic :x
[18:24:05] <[cube]> so i need to find a good reliable way to machine it
[18:24:07] <[cube]> without melting
[18:24:30] <XXCoder> other guy recommanded water pump for fountain as water coolant pump
[18:24:42] <XXCoder> you'd have to re-oil surfaces if its not aluminium
[18:24:48] <XXCoder> so it dont rust
[18:24:51] <[cube]> yea i cant do coolant on mdf machine :/
[18:25:02] <SpeedEvil> [cube]: Air works
[18:25:07] <XXCoder> mines alum but location is real bad
[18:25:09] <[cube]> nice
[18:25:11] <SpeedEvil> [cube]: mist coolant can work too
[18:25:18] <[cube]> i imagine the air will make it messy
[18:25:29] <XXCoder> [cube]: surface it with water repellant first
[18:25:32] <[cube]> wonder if i wcan direct the air to blow chips into vac
[18:25:33] <SpeedEvil> [cube]: is this a MDF cutting machine, or a machine made of MDF or both?
[18:25:35] <XXCoder> mist shouldnt affect it too much
[18:25:46] <[cube]> whole machine is mdf
[18:25:55] <SpeedEvil> What does it cut
[18:26:00] <XXCoder> you
[18:26:02] <XXCoder> ;)
[18:26:03] <[cube]> it does cut mdf, among other woods
[18:26:13] <[cube]> and im experimenting with plastics right now
[18:26:14] <SpeedEvil> A surface on the top of the 'real' deck will make it waterproof to casual misting
[18:26:17] <[cube]> namely acrylic
[18:26:25] <[cube]> yeah i have tremclad on it
[18:26:33] <[cube]> but not on the inner parts
[18:26:35] <XXCoder> SpeedEvil: surifical plate nice
[18:26:40] <[cube]> if liquid seeps in there its over
[18:27:09] <XXCoder> would you be able to bolt down a plastic or metal bin
[18:27:17] <XXCoder> just for misting jobs
[18:27:31] <[cube]> yea im not even gonna go there
[18:27:39] <XXCoder> SpeedEvil: wish there is ultrasonic misting system
[18:27:44] <XXCoder> even finer particles
[18:27:50] <XXCoder> though not too good on lungs
[18:27:57] <SpeedEvil> XXCoder: https://www.youtube.com/watch?v=H16NYnHZ_s0 - water free coolant system?
[18:28:05] <XXCoder> looking
[18:28:44] <SpeedEvil> hmm.
[18:28:55] <XXCoder> fire lol
[18:29:03] <SpeedEvil> It's a pity CO2 dust wasn't harder to make
[18:29:04] <[cube]> i have one of those on my bedside table
[18:29:07] <[cube]> as humidifier
[18:29:13] <[cube]> its like my 3rd one
[18:29:16] <[cube]> they dont last long
[18:29:27] <[cube]> i think if you put anything in there exdcept distilled water it reduces the life
[18:31:04] <XXCoder> yeah might be hackable into water cooling sprayer
[18:31:19] <XXCoder> but nah will get water fountain or something
[18:31:35] <XXCoder> maybe it will work with wd40 lol
[18:31:38] <SpeedEvil> Mist cooling can work quite well
[18:31:47] <[cube]> while back i remember seeing those venturi (sp?) air coolers? was really neat
[18:31:49] <XXCoder> [cube]: thats idea for you too. wd40.
[18:31:57] <SpeedEvil> http://www.ebay.co.uk/itm/Pump-Action-Pressure-Sprayer-5L-8L-10L-For-Water-Fertilisers-Pesticides-Ect-/221894212405?var=&hash=item33a9ecfb35:m:m4uaumHMUkVlJzcbYFbskww
[18:32:14] <SpeedEvil> [cube]: vortex tube
[18:32:21] <[cube]> ya
[18:32:22] <[cube]> http://www.vortec.com/Content/Images/uploaded/homeslides/slide3.png
[18:32:26] <[cube]> really neat
[18:32:32] <[cube]> might try and make one on the lather
[18:32:34] <[cube]> *lathe
[18:32:49] <[cube]> XXCoder: no need for ac if you use a vortex
[18:32:59] <XXCoder> just dont bring it into airport, they might see word "gun" and jail you
[18:33:09] <[cube]> lol
[18:33:17] <SpeedEvil> The vortex tube is very inefficient
[18:33:35] <[cube]> might be okay for low pressure cooling on the bit
[18:33:50] <XXCoder> basically no air compressor here
[18:33:51] <[cube]> and the heat exhaust i can use to heat the shed in winter lol
[18:34:19] <XXCoder> (I said basically because my bro do own big one, but its at inconvient location AND too big)
[18:34:43] <XXCoder> SpeedEvil: your link + 5 gal tank of wd40
[18:34:45] <[cube]> you can get small ones under $100 but they're loud and not sure if you can get a concstant stream out of them
[18:34:46] <XXCoder> nice idea
[18:35:06] <SpeedEvil> XXCoder: Plus a shed full of nitrogen?
[18:37:02] <[cube]> http://www.ebay.ca/itm/Vortex-Cold-and-Hot-Air-Gun-Cold-Air-Gun-Dry-Cooling-Gun-Flexible-Tube-130mm-/252251665407?hash=item3abb5ef3ff:g:qFgAAOSwFqJWmIxA
[18:37:04] <[cube]> not a bad price
[18:37:28] <SpeedEvil> What wattage is your spindle?
[18:37:52] <XXCoder> mines 500w lol (using euro adopotor 750w)
[18:37:53] <SpeedEvil> If your cooler wattage output is not a lot more than your spindle watts, then it's probably not worth it over more cooler airflow
[18:38:17] <[cube]> hmm
[18:38:21] <[cube]> its a Bosch 1618
[18:38:22] <SpeedEvil> And a 2kW compressor cooler might put out ... 100w? of cooling.
[18:38:28] <XXCoder> guys at work I use round stone to sand some fixtures and vise tops
[18:38:31] <XXCoder> whats it called
[18:38:33] <[cube]> 12 amp
[18:38:35] <SpeedEvil> die grinder
[18:39:01] <XXCoder> its not tool grinder its hand type
[18:39:07] <[cube]> i've got a massive compresser here
[18:39:13] <[cube]> about 8ft tall
[18:39:40] <andypugh> Needs compressing :-)
[18:39:45] <[cube]> hehe
[18:39:46] <[cube]> might be worth the experiment
[18:39:58] <XXCoder> compressed compressor
[18:40:07] <[cube]> at that price i could get one for the lathe and mill too
[18:59:33] <XXCoder> [cube]: https://www.youtube.com/watch?v=P76NyJYaSO8
[19:09:18] <XXCoder> [cube]: yeah it uses riciouslu little water
[19:09:27] <XXCoder> it will last long time off one bottle
[19:14:33] <[cube]> nice yeah
[19:14:49] <[cube]> keep in ming the 'stream' of mist isnt that powerful
[19:14:58] <[cube]> not sure how much that matters
[19:15:04] <XXCoder> yeah but then its better than nothing
[19:15:11] <XXCoder> and it will not soak everything
[19:15:19] <arauchfuss> andypugh: Won that auction
[19:15:23] <[cube]> also make sure you can direct it downward
[19:15:27] <arauchfuss> thanks for the advice
[19:15:31] <XXCoder> arauchfuss: good now send it to me ;)
[19:15:33] <[cube]> all the ones i've used seem to only shoot the mist up
[19:15:45] <XXCoder> it has tube so it can be modified
[19:15:51] <[cube]> ah
[19:15:53] <arauchfuss> hah
[19:16:06] <XXCoder> won what anyway :)
[19:16:18] <andypugh> arauchfuss: Cool. I saw it on my suggestions page with no bids and thought you hadn’t bothered.
[19:16:25] <[cube]> XXCoder: another solution....
[19:16:38] <[cube]> could be turning those air duster cans upside down lol
[19:16:41] <arauchfuss> $68 for a renishaw mp3 probe
[19:16:49] <Duc> nice and cheap
[19:16:49] <[cube]> at $2-$2 a can...they'd have to be for special uses
[19:16:54] <arauchfuss> waited till the last 15 min
[19:17:31] <[cube]> *$2-$3
[19:17:36] <XXCoder> crazy
[19:17:43] <[cube]> use a servo to control the flow
[19:17:52] <[cube]> prob get only 1 use out of it per can
[19:17:55] <XXCoder> maybe just connect fountain pump at low power lol
[19:18:10] <[cube]> i'll test it just holding the can over spindle...
[19:18:15] <[cube]> see what happens :P
[19:18:32] <[cube]> i usually buy them in 6-packs
[19:18:32] <arauchfuss> getting a silent compressor in next week.
[19:18:51] <arauchfuss> hope to get a misting system up and running soon
[19:18:59] <[cube]> nice
[19:19:56] <XXCoder> arauchfuss: got link to entry? curious about what you won
[19:20:46] <arauchfuss> http://www.ebay.com/itm/RENISHAW-MP3-PROBE-/262472830722?hash=item3d1c998f02:g:B4QAAOSwKfVXDv~H
[19:21:27] <XXCoder> interesting'
[19:21:37] <XXCoder> I want to make one evenually
[19:22:19] <arauchfuss> andypugh: posted a pic of his probing system based on an mp3
[19:33:48] <membiblio> Evening - Can you do pocketing, using pycam, if your design originated in a 2d tool such as librecad?
[19:36:12] <andypugh> I can’t remember if PyCAM imports 2D
[19:36:27] <andypugh> Pretty sure SheetCAM can do it.
[19:37:27] <membiblio> Andypugh I can search google for SheetCAM but my question is - SheetCAM instead of pycam, which everyone has been recommending? :)
[19:38:06] <andypugh> SheetCAM costs money. PyCAM is Free
[19:39:01] <andypugh> I want to like PyCAM, I nearly started working on it, but it really is very, very slow.
[19:39:04] <membiblio> We already use librecad and freecad and have not yet mastered pycam so I'm not sure it's time to spend cash on a guess :)
[19:39:19] <XXCoder> freecad has cam functions
[19:39:33] <XXCoder> 0.17 has revamped it but havent tried so dunno if any good.
[19:39:36] <membiblio> Hello XXCoder
[19:39:46] <XXCoder> hey
[19:40:09] <membiblio> We are using 0.16 and saw large, for the better, changes from 0.14 to 0.16
[19:40:23] <XXCoder> 0.17 is even better
[19:40:32] <XXCoder> suggest try install freecad-daily
[19:41:37] <membiblio> I'll look for extruding, I think, tutorials. Basically I'd like to route out using LinuxCNC the area around letters leaving the letters on a back of material. I think this is called extruding in CAD terms, right?
[19:42:29] <XXCoder> in 3d modeling making shapes then extending into 3d is extuding yes
[19:42:54] <membiblio> So XXCoder - what does freeCAD do on the CAM front? (So I know what to go looking for) Gcode output?
[19:43:07] <XXCoder> look at Path module
[19:43:44] <membiblio> I see it. Is there any documentation or just experiment?
[19:43:49] <XXCoder> 0.17 Path have been massively updated
[19:43:53] <XXCoder> so dunno
[19:44:12] <membiblio> For the better?
[19:44:14] <XXCoder> docs suck as its still on 0.13 which is very different
[19:44:22] <XXCoder> apparently yes
[19:44:25] <XXCoder> I havent tried 0.17
[19:44:37] <XXCoder> gui there handles better than 0.16
[19:44:57] <membiblio> Very Cool Really
[19:45:35] <XXCoder> though its still not quite ready. quite unpolished
[19:46:25] <membiblio> Hey you turned me onto this don't move until I'm done :)
[19:47:33] <andypugh> If you can bear to use non-free, non-Free, not open-source software that doesn’t actually cost any money, it’s hard to see beyond Fusion360 at the moment.
[19:47:44] <XXCoder> it is
[19:47:55] <XXCoder> I used fusion 360 to make my gage holder
[19:48:29] <XXCoder> what sucks is cloud based storage
[19:48:41] <XXCoder> means they can look at your designs and laugh at it
[19:48:45] <XXCoder> or maybe resell it
[19:49:04] <membiblio> andypugh - I'm 51 and just freaking tired of closed source stuff, software has bitch slapped me for the last time cuz I'm just tired :)
[19:49:14] <enleth> FYI it works rather nice on VirtualBox with 3D accelreation (Dell E7440, integrated Haswell graphics, recent linux Intel driver, Windows 7 in the VM)
[19:49:32] <XXCoder> enleth: it works with no acceleration too
[19:49:35] <XXCoder> though slow
[19:49:43] <enleth> (and of course Guest Additions installed with the experimental Direct3D support)
[19:49:59] <enleth> well, it does, but with accelreation it's not slow anymore
[19:50:07] <enleth> for an integrated graphics card, that is
[19:50:13] <XXCoder> enleth: got any tips on making my r9 270 acceration work?
[19:50:27] <andypugh> membiblio: Yes, and their pricing model (free) does look a bit like a ploy to kill the competition (including the open-source stuff)
[19:50:32] <enleth> XXCoder: natively on Linux or in VirtualBox?
[19:50:36] <XXCoder> both
[19:50:53] <XXCoder> right now acceration on linux "kinda works"
[19:51:09] <XXCoder> firefox dont work with it, so do some games
[19:51:18] <enleth> well, I don't have a linux box with an AMD GPU at the moment, but a friend has r9-280x and I think it works just fine for him
[19:51:37] <XXCoder> whats he use
[19:52:20] <enleth> probably debian, he was using gentoo until quite recently but switched to debian on everything, I guess this includes his desktop PC
[19:52:30] <XXCoder> no drivers wise lol
[19:52:45] <membiblio> andypugh - I gave up MS around January and using Linux Mint (Because it is comfortable but true ubuntu would have been fine as well) and have never been more happier or in control of my destiny. MS has totally screwed the world with W10. JMHO
[19:53:03] <enleth> XXCoder: I'm almost sure it's not the closed source drivers
[19:53:09] <XXCoder> membiblio: they just released service pack 2 with windows 10 fun stuff in it :(
[19:53:15] <andypugh> membiblio: Aye. Luckily Fusion runs on my Mac :-)
[19:53:21] <XXCoder> so I cant update to pre-windows 10 service pack anymore
[19:53:24] <enleth> XXCoder: also, he's using Xen and PCI passthrough for the card
[19:53:26] <XXCoder> enleth: ok
[19:53:33] <enleth> but that doesn't change much
[19:53:58] <enleth> XXCoder: I can ask, I'll be buying this card from him soon anyway
[19:54:09] <XXCoder> ok
[19:54:43] <andypugh> membiblio: Well, actually, I get a free home license for Inventor as a perk of my job, so I use that under Win7 on a VM, and have rather lost track of the FOSS options because of that.
[19:55:05] <XXCoder> andypugh: freecad is getting really good
[19:55:06] <enleth> andypugh: lucky guy
[19:55:14] <XXCoder> cam still some issues but good too
[19:55:25] <membiblio> andypugh - I understand :) Really
[19:55:31] <XXCoder> issues is mostly in docs, there is dreath of docs for it :(
[19:55:50] <membiblio> W10 does run aok in a VM but I'd prefer never to launch the VM
[19:56:17] <andypugh> Bizarrely, I only really use (free) Fusion for the special 3D toolpaths that Fusion has but my version of Inventor doesn’t.
[19:57:11] <enleth> membiblio: there's also OpenSCAD, although it's... different
[19:57:40] <XXCoder> membiblio: https://www.youtube.com/watch?v=c4JUnB1AHdY&feature=youtu.be this might help a little though its still bit older version
[19:57:47] <enleth> membiblio: great for parametric modeling if you're into that kind of thing but the workflow is unlike any other CAD software
[20:16:01] <XXCoder> wow!
[20:16:02] <XXCoder> http://futurism.com/videos/this-new-simple-looking-cell-could-double-generated-energy/
[20:16:33] * SpeedEvil bets it can't.
[20:17:02] <SpeedEvil> Oh - TPV - right
[20:17:16] <XXCoder> TPV?
[20:17:29] <SpeedEvil> thermophotovoltai
[20:17:30] <SpeedEvil> c
[20:17:33] <XXCoder> ahh
[20:18:33] <XXCoder> SpeedEvil: recently USA solar power went over 50%
[20:18:42] <XXCoder> making it majority of power generated
[20:18:56] <XXCoder> for a bit anyway, it will be more and more
[20:19:12] <XXCoder> and if this pans out, it will push solar a long way
[20:23:37] <XXCoder> hey bum
[20:24:18] <enleth> XXCoder: ok, I was wrong, he's using fglrx
[20:24:27] <XXCoder> I'm using same
[20:24:28] <enleth> and he says it works fine
[20:24:41] <XXCoder> its firefox thats relaly annoying me
[20:24:47] <XXCoder> it blacklisted by video card
[21:29:12] <Polymorphism> I got the bearing on
[21:29:39] <Polymorphism> lightly sanded the shaft and then cleaned it, until it slid on snug
[21:29:39] <XXCoder> its a bear to get bearing on hhe
[21:29:54] <Polymorphism> I didnt put the balls back
[21:29:58] <Polymorphism> 9 balls are out
[21:30:02] <Polymorphism> it seems to work without them
[21:30:06] <Polymorphism> george saiud its probably ok
[21:30:13] <Polymorphism> I assembled the Z axis
[21:30:17] <Polymorphism> but put the mounts backwards
[21:30:19] <Polymorphism> so need to redo it
[21:30:43] <Polymorphism> so no problems right now except for concerns about the levelness of the side rails, and some missing hardware on its way
[21:30:46] <XXCoder> forgot what you finally decided to buy
[21:30:50] <Polymorphism> xzero raptgor
[21:30:51] <Polymorphism> mini
[21:31:27] <XXCoder> ahh yea
[21:31:38] <XXCoder> I finally ran mine again yeserday
[21:31:54] <XXCoder> project was a failure lol but it was fine too
[21:32:08] <Polymorphism> lol
[21:32:12] <Polymorphism> what were you making?
[21:32:13] <XXCoder> nylon is mean material
[21:32:33] <XXCoder> gage holder. https://youtu.be/sojJgCfDbp4 if curious
[21:33:11] <XXCoder> it was also project to test new vise, it rocked.
[21:33:45] <Polymorphism> nice, looks solid
[21:34:06] <XXCoder> pretty cheap, its made to be drill press vise lol
[21:34:07] <Polymorphism> what is the rpm
[21:34:12] <Polymorphism> its too fast?
[21:34:12] <XXCoder> rotations per second
[21:34:21] <Polymorphism> I mean how many does it run at
[21:34:33] <XXCoder> oh not too sure, first it was I guess 15,000 rpm
[21:34:50] <XXCoder> later on I ramped it up to I guess 20,000, still not full power (27,000)
[21:38:18] <XXCoder> I also played around with openshot, hence the effects lol
[21:38:27] <XXCoder> I dont think I will use transitions next time
[21:39:24] <Polymorphism> but it still worked so its not a total failure
[21:39:31] <XXCoder> indeed
[21:39:41] <XXCoder> even if it was a total failure i learned a lot
[21:39:45] <XXCoder> and that vise rocks
[21:39:55] <XXCoder> sure its really not fancy one like kurt
[21:40:01] <XXCoder> but it fits in my small router!
[21:41:31] <Polymorphism> where do I get one
[21:41:43] <XXCoder> amazon
[21:42:56] <XXCoder> irwin vise
[21:43:25] <XXCoder> its a drill press vise
[21:44:24] <XXCoder> my gage holder is magic http://picpaste.com/pics/IMG_20160611_220355-PMWqhDZY.1465784242.jpg
[21:45:17] <Polymorphism> that picture is utterly meaningless to me
[21:45:19] <Polymorphism> please explain
[21:45:31] <Polymorphism> it just looks overexposed
[21:45:34] <Polymorphism> I can't tell what anything iss
[21:45:38] <Polymorphism> is that a stovetop
[21:46:31] <XXCoder> lol its gage holder. somehow camera flash make part really shine
[21:46:54] <XXCoder> http://picpaste.com/pics/IMG_20160611_220635-mQYwCLhm.1465784229.jpg
[21:47:17] <Polymorphism> ah nice, I see it now
[21:47:48] <XXCoder> yeah, it does look better after cleaning but still has melted spots and such lol
[21:48:13] <XXCoder> http://picpaste.com/pics/IMG_20160612_010421-eBLCy49u.1465784483.jpg
[21:48:55] <Jymmm> Mine is... a 2x4 =)
[21:49:06] <XXCoder> 2mmx4mm? ;)
[21:49:12] <Polymorphism> how many flute did youy use
[21:49:14] <Jymmm> dead tree
[21:49:19] <Polymorphism> for nylon
[21:49:19] <XXCoder> Polymorphism: 2 too many
[21:52:19] <XXCoder> lol https://youtu.be/5iTTNRE-njM
[21:54:11] <Polymorphism> hungry beast
[21:54:25] <XXCoder> I love how it picks toys up and drop em
[21:54:33] <XXCoder> looks like try touch as much as possible lol
[21:54:48] <Polymorphism> priorities
[21:54:58] <Polymorphism> had to go back
[21:59:24] <XXCoder> lol
[23:18:03] <Flipp_> lookin' to grind/sharpen some tooling. any thoughts on belt sander vs bench grinder?
[23:18:15] <Flipp_> (specifically lathe tool bits)
[23:18:57] <Jymmm> I see belt knife sharpeners
[23:19:12] <Tom_itx> belt will flex more
[23:19:21] <Jymmm> on the professional side that is
[23:19:45] <Flipp_> yeah. I'd love a rockwell 1", but that's a bit much for my lowly shop at the moment :/
[23:20:05] <Flipp_> tom_itx: true. some have a metal backing plate; does that seem to help?
[23:20:06] <XXCoder> Flipp_: woodgears has belt plan
[23:20:16] <Tom_itx> probably so
[23:20:28] <XXCoder> its makable with largely wood, and little bit of additional requirement like motor and belt itse;f
[23:20:46] <XXCoder> Flipp_: http://woodgears.ca/strip_sander/
[23:21:00] <Tom_itx> you will probably get more mileage out of a stone
[23:22:19] <Flipp_> xxcoder: nice. I've entertained the idea of making one myself, but I'd likely to be able to find a chinese one that's made better than my hand at wood :/
[23:22:19] <XXCoder> heh some of steps there you will have easier time because you own a lathe
[23:22:54] <Flipp_> tom_itx: think so? Interesting. I've heard equally many people suggest one or the other
[23:23:38] <Flipp_> tom_itx: belts seem like a good use for removing material at 90*. Feel like I'd have a hard time doing so with the curvature of a wheel
[23:24:16] <Flipp_> xxcoder: yeah. I've got the lathe and a decent manual mill (and a tormach at work), so I'm just looking for an accessory grinder for tooling
[23:24:35] <Jymmm> do realize most belt sanders are NOT setup for wet work
[23:25:26] <XXCoder> lol he owns same vise apparently http://woodgears.ca/strip_sander/strip198-b.jpg
[23:25:58] <Flipp_> jymmm: you mean with flood coolant?
[23:26:10] <Jymmm> Flipp_: Wel, like wet sanding
[23:27:20] <Flipp_> jymmm: yeah, true. I'm not expecting a mirror finish or anything; more just sharpening tools and the occasional removal of some stock from a part
[23:27:42] <Jymmm> Flipp_: I'm talking about heat build up changing the temper
[23:32:13] <Flipp_> ah, good point
[23:33:08] <Flipp_> is it common to do wet grinding on a bench grinder? I haven't noticed many videos of people doing actual wet sharpening, though I can see how it could affect the temper
[23:43:10] <enleth> Flipp_: there are special bench grinders for wet grinding, with the wheel in a small basin of sorts
[23:44:01] <enleth> more expensive and a bit finicky to use, I haven't seen one with both a water basin and a good rest yet
[23:44:17] <enleth> but if you find one, it's probably wort it
[23:44:20] <enleth> *worth
[23:59:37] <Jymmm> Test of various two-part epoxies.. https://www.youtube.com/watch?v=bM4IGweHT2k
