[02:13:20] <Deejay> moin
[02:17:37] <Crom> I'm waiting on some 3mm and 4mm end mills for finishing my 80% AR lower
[05:55:24] <Demure_> My Emco 5's independent 4-Jaw chuck has reversible jaws, which is a necessity for larger diameters, however then the inner grip becomes stepped, so while the jaws can grab 12mm, when reversing them they can only grab 5mm, which seems silly for larger diameters (Say 50mm, sticking out 90-100mm), right?
[05:55:59] <sync> nah, it's enough
[05:56:59] <Demure_> Really? What max RPM would you say for 50mm dia, 90mm lenght grabbed by 5mm?
[05:57:51] <Demure_> No headstock possible sadly.
[05:59:22] <jdh> inside jaw a Vee, outside a radius?
[06:00:31] <sync> as much as you need
[06:00:39] <Demure_> What do you mean with that, jdh?
[06:00:52] <jdh> the profile of the jaw
[06:00:57] <Demure_> Ah, yes, inside jaw is a V shape and the outside is a radius
[06:01:03] <sync> obviously you should not be taking incredibly hard cuts but eh
[06:01:07] <Demure_> So when reversed it's clamping with the radius which would make more sense for inner clamping
[06:01:18] <Demure_> It's a small lathe, no hard cuts happening anyway :)
[06:07:44] <jthornton> morning
[06:07:59] <XXCoder> yo
[06:08:08] <XXCoder> jthornton: check this out lol https://www.thingiverse.com/thing:1804112
[06:08:27] <XXCoder> cant do that shit with cnc that cuts anything :P
[06:10:00] <jthornton> wonder what he is trying to fix?
[06:10:12] <XXCoder> jthornton: he?
[06:10:22] <jthornton> going to pick my hot glue kit up at the post office today
[06:10:29] <XXCoder> should say "you" lol
[06:10:42] <jthornton> the z anti-wobble decoupler
[06:10:48] <XXCoder> yeah look at who made it
[06:11:07] <jthornton> lol I just woke up and still foggy
[06:11:35] <jthornton> ok, what did you fix with that?
[06:11:35] <XXCoder> np
[06:11:51] <XXCoder> it stops screw wobblyness from affecting print
[06:12:22] <jthornton> the screw is not straight?
[06:12:40] <XXCoder> its chinese
[06:12:49] <jthornton> oh
[06:12:49] <XXCoder> im surpised its not a loop ;)
[06:12:54] <jthornton> lol
[06:13:00] <XXCoder> ugh https://www.kickstarter.com/projects/hindtechnology/masso-the-all-in-one-cnc-controller
[06:13:09] <XXCoder> insane price :P way too expensive
[06:13:30] <jthornton> saw that the other day
[06:14:27] <XXCoder> got to admit its pretty cool but so pricy
[06:14:42] <jthornton> if it was modular it would be a good thing but you break one bit you loose the whole package
[06:14:53] <jthornton> he should look at the AD Click
[06:15:21] <XXCoder> im still waitiong for 3 tb6600s and BOB
[06:16:35] <jthornton> from china?
[06:17:26] <XXCoder> yeah
[06:17:37] <XXCoder> then I evenually need to figure some stuff
[06:17:47] <XXCoder> spindle control mainly
[06:20:50] <jthornton> I'll see how much fun the kit is after while when I pick it up
[06:21:38] <XXCoder> you will run into bunch issues like I did lol
[06:21:39] <archivist> Demure_, if something sticks out too far use tailstock support
[06:21:55] <jthornton> how did the 2020 beam support work out?
[06:22:08] <XXCoder> I suggest first thing to print is my decoupler, and 90 degree support
[06:22:25] <XXCoder> its very good. you just need one since other side have limit switch on way anyway
[06:22:34] <_methods> jdh: looks like you better put up your umbrellas
[06:22:49] <XXCoder> I plan to modify design so can bolt sides too for even stronger connection.
[06:23:03] <XXCoder> though honestly it dont really need that
[06:23:24] <jthornton> guess I better order some filament today
[06:23:53] <XXCoder> yeah throw away chinese filiment
[06:24:09] <XXCoder> use it to test shit you dont wanna waste quality filiment on
[06:24:09] <jdh> umbrellas up. boat double tied and insured
[06:24:25] <_methods> looks like it's gonna stay out away from us
[06:24:27] <XXCoder> I haven't thrown mine away but I plan to
[06:24:33] <_methods> you guys get blasted all the time
[06:24:54] <Jymmm> "...all future updates will be emailed for free" Um, EMAILED? Yeah... NOT!
[06:24:58] <jdh> charleston could be worse
[06:25:05] <_methods> we'll see
[06:25:17] <_methods> so far it's lookin like it's stayin out awya
[06:25:42] <_methods> very thoughtful of it to come thru on a weekend
[06:25:52] <_methods> very considerate hurricane
[06:26:14] <Jymmm> Eh, blow me!
[06:26:19] <XXCoder> Jymmm: reminds me of one isp that had tech support, email only
[06:26:25] <XXCoder> figure it out
[06:26:38] <jthornton> I wonder if part of the problem is the end of the leadscrew is not machined?
[06:26:49] <Jymmm> XXCoder: Or the software limited qty of axis
[06:27:24] <XXCoder> that kicker I linked to?
[06:27:31] <XXCoder> isnt it limited by connectors anyway?
[06:27:34] <jdh> morning models skirt the coast
[06:27:42] <_methods> yeah
[06:27:52] <Jymmm> XXCoder: Yeah. Shit like that is why ppl are moving away from vmware
[06:27:55] <_methods> another boatload of rain
[06:28:12] <XXCoder> nice and rainy week here
[06:28:32] <Jymmm> XXCoder: You have to create an account, and login just to get an update.
[06:28:40] <XXCoder> what?
[06:28:45] <XXCoder> what if they go tits up
[06:29:00] <_methods> looks like they're predicting only cat2 by time it hits us
[06:29:01] <Jymmm> XXCoder: vmware company products, even for the free stuff
[06:29:01] <jdh> best outlook shows heading inland by you
[06:29:23] <Jymmm> XXCoder: Your phucked?
[06:29:25] <XXCoder> im not too sure what you mean by "vmware"
[06:29:39] <Jymmm> XXCoder: htp://vmware.com/
[06:29:47] <Jymmm> bah
[06:29:51] <Jymmm> XXCoder: http://vmware.com/
[06:29:58] <XXCoder> I know what it is, virtual machine software
[06:30:03] <XXCoder> thats why im bit confused
[06:30:15] <XXCoder> they have weird license or something?
[06:30:47] <Jymmm> XXCoder: Vmware company policy is that even to get docs, you MUST have an account
[06:30:52] <XXCoder> ahh
[06:31:21] <Jymmm> XXCoder: Go from OSX 01.9 to 10.10, you PAY for an update.
[06:31:28] <Jymmm> 10.9*
[06:31:48] <Jymmm> XXCoder: go from 10.10 to 10.10.5 you PAY for an updte
[06:32:32] <Jymmm> XXCoder: and they WILL (and have) disabled your older version you bought if you update your OS
[06:32:49] <XXCoder> geez
[06:33:26] <Jymmm> XXCoder: Not disable, just "You can't run this is this version", so basically a "Fuck you and have a nice day"
[06:34:24] <Jymmm> XXCoder: I had to convert VM's other to vbox for a few friends who all updated to the lastest OS
[06:34:52] <XXCoder> seriosuly thats like "any change? blow me or it dont work"
[06:35:04] <XXCoder> way too sensive to breakage for corprate relibability needs
[06:35:38] <Jymmm> XXCoder: Oh they got you covered, as long as the check doesn't bounce.
[06:37:45] <Jymmm> XXCoder: The thing is virtualization is what's in. You can run an entire corp on two pachines, and virtualize it all
[06:37:54] <Jymmm> machines*
[06:38:10] <XXCoder> yeah though fewer machines mean more crippling when one goes down
[06:38:37] <Jymmm> Not at all, the two machines (hardware) is for redundancy.
[06:39:06] <XXCoder> depends on how many 9s reliability you need really
[06:39:09] <Jymmm> cripling? nope, just revert from snapshot and you're back up and running
[06:40:11] <Jymmm> XXCoder: That's marketing hype (the 9999.99999%), NOBODY can guarntee anything, and if they do, what you don't pay the host for a month, but lose $2m in revenue?
[06:40:53] <XXCoder> I know of setups where there is entire backup server cluster, in completely different city, ready to instantly take pver
[06:41:02] <XXCoder> thats 5 9s if I recall
[06:41:05] <XXCoder> 99.999%
[06:41:14] <XXCoder> thats maybe 5 minutes a year
[06:42:06] <Jymmm> XXCoder: Eh, thats common, we had in calif , tx, ny, and uk concurrently. doens't mean shit if theres a fuber cut =)
[06:42:15] <XXCoder> indeed
[06:42:16] <Jymmm> fiber*
[06:42:34] <XXCoder> I remember that time chinese had 6 fiber cables cut by boat guys
[06:42:45] <XXCoder> acciently. maybe.
[06:43:13] <Jymmm> XXCoder: or there was a guy going to all the fiber point in the SF Bay Area and cutting fiber bundles
[06:43:49] <XXCoder> crazy. what was guy doing that for? did guy ever reveal that
[06:44:10] <Jymmm> He was only cutting Verizon fiber =)
[06:44:26] <XXCoder> revenge i guess
[06:44:32] <Jymmm> yeah
[06:46:03] <Jymmm> Most construction company go bankrupt if they are digging and cut a fiber, as it's $1m/hour typically, can be more too
[06:46:14] <XXCoder> owww
[06:46:17] <XXCoder> call before you dig
[06:47:59] <Jymmm> We had a fiber cut a couple of months ago, took out all cell and data up here on the ridge. It was a mismarked fiber that P&GE cut 100 miles away
[06:49:56] <Jymmm> by data, I mean *ALL* internet access, dsl, mobiles data, etc
[06:50:14] <jthornton> XXCoder: did you print the fan shroud for yours?
[06:50:35] <XXCoder> dual duct fan? yeah i had to remove iut, it ruined one print by falling off
[06:50:51] <XXCoder> its back to stock fan setup.
[06:50:54] <jthornton> wow falling off is not good
[06:51:09] <XXCoder> yeah it seriously misligned print
[06:51:10] <Jymmm> We were in the dark ages of no internets.... CONNECT 9600 BAUD
[06:51:32] <XXCoder> heh isnt phones across fiber nowdays too
[06:51:50] <Jymmm> XXCoder: in new buildouts yes
[06:51:59] <XXCoder> how long they fix
[06:52:26] <Jymmm> XXCoder: but I have a pots line too
[06:52:32] <Jymmm> XXCoder: 2 days
[06:52:40] <XXCoder> havent had one for over a decade
[06:53:00] <XXCoder> I had em for years before, because need one to call people using tty
[06:53:00] <Jymmm> Yeah, most dont.
[06:53:09] <XXCoder> and later internet access
[06:53:24] <XXCoder> then stopped after at&t@home
[06:53:25] <Jymmm> pots line work during a blackout =)
[06:53:38] <XXCoder> yeah it dont work for me, tty need power LOL
[06:53:58] <Jymmm> XXCoder: you need a line powered tty =)
[06:54:12] <XXCoder> ow that'd be serious challenge to design
[06:54:25] <XXCoder> but then last tty was designed in 2003 or so?
[06:54:28] <XXCoder> texting killed it
[06:54:32] <Jymmm> XXCoder: http://www.instructables.com/id/Phone-line-powered-flashlight/
[06:55:08] <XXCoder> heh that'd be nice blackout backup light
[06:55:12] <XXCoder> add light sensor and done
[06:55:19] <Jymmm> =)
[06:55:34] <Jymmm> but, like you said... nobody has pots line these days
[06:55:35] <XXCoder> is jack still powered when not set to a number?
[06:56:06] <Jymmm> not sure
[06:57:36] <Jymmm> jthornton: Are you still struggling near the end of each month (data wise) ?
[06:57:57] <jthornton> not lately
[06:58:11] <Jymmm> jthornton: they gave you more bandwith?
[06:58:12] <jthornton> turned off my wifes wifi on her phone lol
[06:58:18] <Jymmm> oh, hahaha
[06:58:38] <jthornton> also free time till 8am now
[06:58:49] <jthornton> so do all my surfing and downloading then
[06:58:53] <Jymmm> instead of 6am?
[06:59:09] <Jymmm> cool
[06:59:53] <jthornton> before free time was midnight to 4am or something like that
[07:00:02] <jthornton> new plan is 4am to 8am
[07:00:06] <XXCoder> mines 2 am to 5 am lol
[07:00:20] <Jymmm> eeeesh
[07:01:22] <Jymmm> XXCoder: you on satellite too?
[07:01:28] <XXCoder> nah
[07:01:32] <XXCoder> comcast
[07:01:57] <Jymmm> ah
[07:02:18] <XXCoder> been on it since it was att&t@home lol
[07:05:07] <XXCoder> "780ti Classified backplate"
[07:05:12] <XXCoder> "part for friend"
[07:05:14] <XXCoder> ummm
[07:05:25] <XXCoder> hope thats not goverment secret desigb plate :P
[07:05:40] <XXCoder> not that it shows anything useful
[07:05:46] <XXCoder> https://www.thingiverse.com/thing:1803984
[07:07:05] <jthornton> XXCoder: you are being followed...
[07:07:42] <XXCoder> oh that's all
[07:08:14] <jthornton> I have one of these to build a bigger printer http://www.reprapdiscount.com/mechanics/64-bulldog-xl-extruder.html
[07:08:35] <XXCoder> so you can then build even bigger printer?
[07:08:55] <jthornton> yea, once I get the hang of printing
[07:09:06] <XXCoder> I do want a delta but dunno lol
[07:09:19] <jthornton> looked at core xy but don't like the z much
[07:09:36] <XXCoder> supported one side if I recall
[07:09:47] <XXCoder> dont think can apply anti-wobble with that
[07:13:58] <jthornton> the bulldog xl I have can use 1.75 or 3mm filament
[07:14:19] <jthornton> just need a e3d for it and I'm ready to go
[07:14:19] <XXCoder> what about 1 cm filiment?
[07:15:35] <jthornton> thats pretty big lol
[07:15:46] <XXCoder> yeah and nonexistant lol
[07:15:49] <Jymmm> jthornton: you are going the glorified hot glue gun too? *sigh*
[07:16:11] <XXCoder> its just hot glue machine yeah but hella fun too lol
[07:16:34] <Jymmm> XXCoder: but shitty results (till you get into the $100K range)
[07:16:40] <XXCoder> yeah
[07:16:54] <XXCoder> I improved mine a bunch, its very nice now
[07:17:08] <XXCoder> anti-wobble was hassle but worth it
[07:17:51] <Jymmm> I dont want to know ;)
[07:18:12] <XXCoder> its just not something we worry about with cnc mill or routers
[07:18:17] <XXCoder> usually anyway
[07:18:21] <Jymmm> heh
[07:18:50] <XXCoder> and solution is impossiblke anyway, it disconnects X assembly from Z axis screw
[07:18:53] <Jymmm> I'd rather have the optical resin instead
[07:19:04] <XXCoder> if it tried to cut it would just randomly lift off and fall
[07:19:15] <XXCoder> its pure additive only solution
[07:22:16] <Jymmm> https://www.sculpteo.com/en/materials/polyjet-resin-material/
[07:23:03] <XXCoder> very nice, too bad its so expensive
[07:25:57] <Jymmm> XXCoder: https://www.youtube.com/watch?feature=player_detailpage&v=GJnoSPgJtE4#t=141
[07:27:07] <Jymmm> https://www.youtube.com/watch?v=O2thSsQrZUM
[07:27:57] <XXCoder> yeah seen that before
[07:28:05] <XXCoder> amazing but "ink" is expensive
[07:54:58] <Jymmm> XXCoder: $40K/year LEASE, min 3 years
[07:55:47] <Jymmm> Resin... $99/800mL and up from there =)
[08:08:45] * jthornton cools down after the work out
[08:11:26] <jthornton> http://www.thingiverse.com/thing:633074
[08:37:12] <gregcnc> lol https://www.instagram.com/p/BLFFRLWhefV/?hl=en
[08:38:42] <AndChat|234416> :D
[08:42:23] <gregcnc> it's interesting now that everyone can record stuff you get multiple angle of idiots being idiots https://www.yahoo.com/news/watch-ford-mustang-shelby-gt350-151601789.html
[08:54:04] <cradek> the curb actually stopped it
[08:54:46] <gregcnc> yeah, would have been injuries otherwise
[09:05:27] <archivist> and now he will have trouble claiming on the insurance har har
[09:25:06] <MacGalempsy> time for new rack abd pinion, a arms, rim, motor mounts, etc... ask me how i know :)
[09:28:54] <archivist> you broke something
[09:38:28] <cradek> pretty sure the combination of front wheel drive and traction control in my car would make doing that impossible
[09:48:24] <Demure_> Holy moly inserts can make a huge difference
[09:48:38] <Demure_> Had some Sandvik inserts designed for steel and was using them on brass and always got meh-surface finish
[09:48:54] <Demure_> Got some cheap-o eBay quality non-ferro inserts and I can hardly see any toolmarks
[09:49:47] <MacGalempsy> cool
[09:50:25] <archivist> for brass, learn to grind hss
[09:51:36] <Demure_> I'm worried about repeatability with HSS
[09:51:43] <archivist> I think insert prices are similar to printer ink :)
[09:52:16] <Demure_> The cheaper the better? <: I think the biggest change is that I now have some inserts meant for their task
[09:52:37] <Demure_> I've ordered a set of Korloy inserts for non-ferro so we'll see
[09:52:55] <Demure_> Either way I'm happy to find out it's not something machine-wise that was stopping me from getting good results
[09:56:53] <gregcnc> sharp edge inserts work well in all materials on small machines due to low cutting force.
[09:57:38] <MacGalempsy> i hear the right rpm works good too
[09:58:53] <gregcnc> In production you'd be using coated steel inserts with coolant and this works just fine.
[09:59:10] <gregcnc> steel grade that is
[10:00:30] <MacGalempsy> archivist: any pickup in the work orders this week?
[10:09:11] <archivist> none
[10:16:00] <MacGalempsy> Time to start making stocking stuffers
[10:17:20] <MacGalempsy> does the UK do a lot of craft shows? here they are everywhere every weekend
[10:20:08] <archivist> that costs to exhibit and get to
[10:21:25] <SpeedEvil> archivist: what do you actually do? Do you have a 'this is what I do for money' page?
[10:21:38] * SpeedEvil cues 'Private Dancer'.
[10:22:27] <archivist> I have my gears.archivist.info page
[10:32:20] <MacGalempsy> ever consider battling clickspring on clock making? heh
[10:34:53] <archivist> you mean like http://www.collection.archivist.info/archive/DJCPD/PD/2008/2008_07_15_Webb_Clock/P1010009.JPG
[10:35:26] <MacGalempsy> :D
[10:36:58] <archivist> commissions like that are not common
[10:42:55] <MacGalempsy> make you tube videos and get the ad money :) your product will make you famous
[10:44:38] <MacGalempsy> that would mean you have to signup for a google account. lol
[10:44:48] <archivist> 600k views is not getting me work
[10:45:23] <MacGalempsy> you have 600k views?
[10:45:34] <archivist> on one vid
[10:45:47] <MacGalempsy> is your contact info in it?
[10:46:46] <archivist> people used to ask questions, not seen one in years
[10:47:06] <archivist> 660k https://www.youtube.com/watch?v=HAtziCsUj5Q
[11:06:56] * JT-Shop needs to quit playing with the HGM and get back to work lol
[11:10:10] <CaptHindsight> most people would think that they could just glue gun the gear
[11:11:16] <archivist> why cant you make it for ef all like the chines do
[11:11:40] <CaptHindsight> and how many people will actually fix an old machine vs replace it?
[11:12:02] <archivist> not many these days
[11:12:16] <archivist> which is silly
[11:12:24] <CaptHindsight> how many even know how to search for anything?
[11:12:35] <archivist> even fewer
[11:13:31] <CaptHindsight> I bet that if you had gearsgearsgearsgears.com a few % of the leads generated would be viable
[11:14:43] <pink_vampire> I just finished the main back plate for the bottom part of the panel.
[11:16:51] <pink_vampire> the part is fully functional. but it wasn't a new aluminum sheet, so it have some deep scratches and marks.
[11:17:30] <pink_vampire> any idea how to hide them?
[11:18:08] <pink_vampire> archivist: ?
[11:18:19] <CaptHindsight> a toy machine that made plastic gears back in the 50-70's would have been a big seller
[11:18:38] <MacGalempsy> sweet, just found the drims for this weekends forge project
[11:18:38] <archivist> pink_vampire, "finishing"
[11:18:50] <MacGalempsy> *drums. $8
[11:19:26] <CaptHindsight> *duino and Rpi are the Erector Sets of today
[11:19:44] <pink_vampire> I've tried to sand it down a bit, but it's too deep
[11:19:49] <CaptHindsight> and cnc glue guns
[11:19:58] <archivist> just keep sanding
[11:20:02] <pink_vampire> about paint. I never did any paint job
[11:20:07] <roycroft> are you going to paint this panel, pink_vampire?
[11:20:09] <archivist> start with coarse
[11:20:59] <roycroft> if so, then clean it really well, use some body filler (or even jb weld, but sanding that is a lot of work) to fill in the scratches, then sand smooth and paint
[11:21:10] <archivist> learning to go through the wet and dry grades to get shiny is well worth the effort
[11:21:49] <MacGalempsy> if it looks like crap without paint, it will likely look bad with paint unless sanded
[11:21:50] <roycroft> this is assuming the scratches are too deep to sand out
[11:21:50] <archivist> people dont realise the steps that makes sanding easier
[11:22:09] <roycroft> paint does not cover up flaws, indeed
[11:22:12] <roycroft> well
[11:22:14] <roycroft> most paint doesn't
[11:22:22] <roycroft> thick, hammered finish paint will hide a lot of stuff
[11:22:23] <archivist> belt sander, nothing is too deep :)
[11:22:31] <roycroft> but it looks like you're hiding stuff
[11:22:57] <pink_vampire> I'm thinking about cover it with vinyl sheet, but I can't find anything glossy large in a retail store
[11:22:59] <roycroft> a belt sander in the hands of an inexperienced person will usually do more harm than good
[11:23:03] <gregcnc> just spanding until thickness is 0.000, and get a new plate minus scratches
[11:23:16] <CaptHindsight> 3-4 heavy coats of thick primer :)
[11:23:20] <roycroft> a random orbital sander is a lot more user friendly
[11:23:43] <MacGalempsy> any thoughts on a 3 part vs 2 part furnace?
[11:23:55] <roycroft> pink_vampire: do you have any pictures of this scratchy panel?
[11:23:55] <archivist> I actually use flat sheets on a hard surface
[11:24:21] <pink_vampire> one sec. let my take a picture of it
[11:24:24] <roycroft> it would be easier to advise if we knew how deep the scratches are
[11:26:00] <archivist> get a set of http://www.metalclay.co.uk/3m-polishing-papers-12-sheets/
[11:26:09] <roycroft> aluminium is pretty soft stuff
[11:26:12] <roycroft> easy to sand
[11:26:22] <roycroft> but you need to start with open grit sandpaper
[11:26:32] <roycroft> or else it will clog up really quickly
[11:27:01] <CaptHindsight> how about chemical etching?
[11:27:12] * roycroft would argue that aluminium can be too easy to sand
[11:28:58] <CaptHindsight> http://www.finishing.com/148/47.shtml
[11:30:58] <pink_vampire> http://i.imgur.com/MIh0kZD.png
[11:31:53] <pink_vampire> the is is the problematic area
[11:32:02] <pink_vampire> this*
[11:32:53] <roycroft> do those scratches catch your fingernail?
[11:32:58] <archivist> minor marks
[11:33:27] <pink_vampire> archivist: i don't need it mirror finish, just nut very ugly.. after all it's just the plate that hold the power supply in the electrical panel
[11:33:45] <roycroft> you can easily attain a mirror finish if you wanted to
[11:34:03] <archivist> 80 grit, then 120 grit, then 240 then 800, 1200, 2000
[11:34:04] <roycroft> start with 80 grit sandpaper in a random orbital sander
[11:34:22] <roycroft> sand it until all the scratches are gone
[11:34:25] <gregcnc> close the panel door?
[11:34:27] <roycroft> then clean it
[11:34:42] <roycroft> so you remove any loose grit from the first sanding
[11:34:45] <roycroft> clean your sander as well
[11:34:53] <roycroft> i usually blow off the sander between grits
[11:34:55] <roycroft> then move to 120
[11:34:56] <pink_vampire> gregcnc: I have even light in the panel..
[11:35:07] <gregcnc> turn off the light as well
[11:35:12] <roycroft> sand with 120 until all the coarse swirl marks from the 80 grit are gone
[11:35:13] <pink_vampire> I have 220 and 800 grit
[11:35:18] <archivist> ew, someone subscribed to me on yooootooob
[11:35:26] <roycroft> then you don't have enough sandpaper :)
[11:35:35] <roycroft> after 120 then go to 180
[11:35:37] <roycroft> then 240
[11:35:41] <roycroft> 320
[11:35:43] <roycroft> 400
[11:35:44] <pink_vampire> archivist: link to your channel...
[11:35:47] <gregcnc> I'd get a wire wheel and just brush the rest to hide it
[11:35:50] <roycroft> then see what it looks like
[11:35:52] <archivist> you need a set of papers
[11:36:05] <roycroft> 400 grit will leave a nice, somewhat matte finish
[11:36:10] <pink_vampire> wire wheel don't work nice
[11:36:33] <roycroft> if you want a better finish then move to 600 grit, then 1000
[11:36:35] <gregcnc> A light in the cabinet is useful, shouldn't power be locked out while you're working in there?
[11:36:46] <archivist> my first mirror finish was at school on a name tag we had to make
[11:36:51] <roycroft> and after 1000 grit then you can switch to a polisher with a lambswool pad
[11:37:16] <roycroft> you must work progressively through the grits
[11:37:29] <roycroft> and you must remove all swirl marks from the previous grit before moving on to the next one
[11:38:11] <archivist> going up through the grades is faster than trying with the wrong grade
[11:38:21] <roycroft> if you take shortcuts it will look horrible
[11:38:27] <roycroft> and what archivist said
[11:39:06] <roycroft> you can get sanding disks up to 320 grit for a random orbital sander
[11:39:08] <archivist> must be 1966 ish, is when I first did it
[11:39:14] <roycroft> beyond that it's time for wet/dry paper and hand sanding
[11:39:45] <roycroft> but with the finer grits, if you've prepared the surface properly, it should only take a couple minutes per grit
[11:40:44] <roycroft> if you skip a grit it could take a half hour to get a good finish with the next grit, and you would consume many sheets of sandpaper
[11:40:48] <roycroft> so don't skip a grit
[11:43:18] <archivist> and... file--->burnisher for some work
[11:43:39] <roycroft> when you finish with the 80 grit you'll have removed all the scratches and you'll be left with a surface that is uniformly covered with fairly large peaks and valleys
[11:43:58] <roycroft> if you keep sanding with 80 grit you'll be wearing down the peaks, but also deepening the valleys
[11:44:21] <roycroft> when you move to 100 grit you'll be knocking down the peaks and not getting into the valleys
[11:44:43] <roycroft> but if you skip 100 grit and move on to 180 grit you'll onlyl be nicking the tops of the peaks
[11:45:05] <roycroft> and it will take a long, long time to wear them down to where they're appreciably closer to the valleys
[11:46:25] <roycroft> and if you keep going without wearing down the peaks eventually you'll have very smooth, shiny plateaus sitting above the valleys
[11:46:39] <roycroft> and the surface will look shiny but full of microscratches
[11:46:58] <roycroft> your goal is to keep knocking down the peaks until they are level with the valleys
[11:50:10] <Jymmm> roycroft: explosives work pretty good for that ;)
[11:51:09] <CaptHindsight> https://www.etsy.com/listing/273693974/bulk-100-mixed-bronze-steampunk-gear?ref=market what people expect to pay for small gears
[11:52:05] <Jymmm> CaptHindsight: too expensive... https://www.etsy.com/listing/460588684/bulk-50-mixed-bright-silver-steampunk?ref=related-1
[11:52:54] <CaptHindsight> Jymmm: those are only silver
[11:53:25] <Jymmm> I have spray paint
[11:53:36] <CaptHindsight> sounds complicated
[11:53:51] <CaptHindsight> is any sanding involved?
[11:54:47] <Jymmm> CaptHindsight: Nah, just sulfuric acid bath
[11:55:23] <CaptHindsight> for you or the parts?
[11:55:55] <Jymmm> for relaxation
[11:58:22] <CaptHindsight> nevermind, looks like somebody discovered star lock washers instead of gears for steampunk
[11:59:18] <CaptHindsight> almost 3 million views for wood gear making https://www.youtube.com/watch?v=oNuhr3htNWs
[12:00:09] <CaptHindsight> cut by eye and printed template
[12:01:38] <CaptHindsight> I bet a cheap cnc machine to cut wood gears would be popular
[12:03:20] <CaptHindsight> people need step by step guides as well
[12:03:34] <Demure_> It's not just 3 Million views just for the gears: It's also Matthias Wandel
[12:04:19] <Demure_> There's actually a video on that channel of him doing the template on a scrollsaw vs the same template on a CNC router
[12:04:57] <CaptHindsight> looks like he has several videos of machines made from wood
[12:05:51] <Demure_> Yup, guy's pretty good with wood
[12:05:59] <archivist> jeeeeesus low grade
[12:06:03] <Demure_> Mostly known for his wood-working pantograph machine
[12:06:16] <CaptHindsight> I can envision an entire series using progressively better materials
[12:06:20] <Demure_> He's more of a doesn't-matter-how-it-looks, if-it-works-it-works
[12:06:34] <CaptHindsight> but I get it, WOOD
[12:06:42] <archivist> I can hear how bad the mesh is
[12:06:53] <gregcnc> wow he has ~270M channel views
[12:07:03] <Demure_> He's one of the most popular woodworkers on YouTube
[12:07:15] <Demure_> I've used his generators a few years ago when I got started with machine working, did the job back then and most of the other gear software was far too complex for me at that point
[12:07:37] <Demure_> Just exported the result straight to PDF for lasercutting
[12:13:33] <CaptHindsight> hasn't anyone come up with a gimmick using cheap composites?
[12:15:06] <archivist> the trouble is all the crap techniques like that, make people expect a good gear to be as cheap
[12:15:55] <CaptHindsight> maybe gears as art
[12:16:33] <gregcnc> people just have no idea what good is
[12:16:48] <gregcnc> when good enough is dirt cheap
[12:16:56] <CaptHindsight> Brand is good
[12:17:06] <CaptHindsight> they have been well trained
[12:17:45] <Jymmm> CaptHindsight: composites? Such as?
[12:17:46] <MacGalempsy> Brand names = good?
[12:18:06] <Jymmm> MacGalempsy: Yeah, like Spark-O-Matic
[12:18:30] <gregcnc> anyone use gearotic motion?
[12:18:48] <MacGalempsy> heh.
[12:18:57] <MacGalempsy> Yugo is a brand name
[12:19:17] <CaptHindsight> MacGalempsy: not just any brand
[12:19:34] <MacGalempsy> ok. was waiting for that
[12:19:34] <CaptHindsight> it depends on the marketing propaganda
[12:20:56] <CaptHindsight> especially status symbols
[12:26:25] <Jymmm> CaptHindsight: composites? Such as?
[12:27:00] <CaptHindsight> Jymmm: wood waste and PVA
[12:27:09] <Jymmm> ah
[12:27:25] <gregcnc> oh mdf extrusion machine
[12:28:17] <CaptHindsight> paper waste and PVA
[12:44:10] <IchGucksLive> hi
[12:46:36] <IchGucksLive> reinstalling the wheezy pc's to 12.ß4
[12:47:50] <CaptHindsight> IchGucksLive: problems with Wheezy?
[12:54:07] <IchGucksLive> ubuntu man is not debian
[13:05:52] <roycroft> indeed, it is not
[13:16:20] <IchGucksLive> somone knows where i can get the mnue inside the open frame not in top panell
[13:19:58] <IchGucksLive> indicator-appmenu deinstall ;-)
[13:22:43] <IchGucksLive> found my loving synaptics HAPPY
[13:23:00] <CaptHindsight> what was the idea behind Ubuntu? Start out with a easy to use Linux distro that worked on most PC's and then slowly boil it like the frog (change and rename most everything)....
[13:23:13] <IchGucksLive> its like Win98se the best is missed all over
[13:24:26] <CaptHindsight> and start selling features? or what?
[13:29:06] <roycroft> ubuntu was an attempt to graft the cruftiness of windows onto debian
[13:29:29] <roycroft> because people don't feel comfortable working with operating systems that are efficient and non-problematic
[13:30:30] <gregcnc> like cars you have to control yourself?
[13:30:54] <roycroft> yes
[13:31:13] <IchGucksLive> i like not to update and that is not how the world works
[13:31:15] <gregcnc> but you'll be able to watch movies instead
[13:31:25] <CaptHindsight> did they have too much lead in the company drinking water?
[13:31:29] <roycroft> it's much more preferable to sit back, watch pr0n, eat cheetos, and crash into a truck and die, blaming it on the software, than to actually be alert, attentive, and operate a vehicle safely by oneself
[13:32:40] <gregcnc> I imagine I'll be the ahole on the road 30 years from actually driving his car
[13:32:57] <gregcnc> will traffic police cease to exist?
[13:34:16] <roycroft> aah, there's the rub
[13:34:26] <roycroft> the thing that may make self-driving cars a big fail is that they will refuse to speed
[13:34:31] <roycroft> and people will not accept that
[13:34:42] <roycroft> they will also refuse to cut people off
[13:35:04] <roycroft> road rage must not be eliminated
[13:35:09] <roycroft> it is our god-given right
[13:35:16] <gregcnc> until people vote to raise limits because iDrive will be so safe
[13:35:22] <roycroft> it can only be replaced by automated, programmabile road rage
[13:35:28] <roycroft> people don't vote on speed limits
[13:35:37] <gregcnc> no you'll just facebook you rage
[13:35:40] <roycroft> state departments of transportation make those decisions
[13:35:47] <roycroft> and they ignore the will of the people
[13:35:53] <gregcnc> uh those are people
[13:35:59] <roycroft> no
[13:36:02] <roycroft> they are bureaucrats :)
[13:36:04] <gregcnc> our limits increased recently
[13:36:25] <roycroft> our state legislature voted several years ago to authorize raising the speed limit in some rural areas
[13:36:39] <roycroft> our dot reluctantly did so to a very limited degree this year
[13:36:46] <roycroft> and only under pressure from the legislature
[13:38:05] <gregcnc> good will bea cheaper because robotrucks will work 24/7
[13:38:47] <gregcnc> and drones will deliver tacos right to your mouth
[13:38:50] <gregcnc> i can't wait
[13:39:00] <roycroft> we don't need no stinking drones
[13:39:07] <roycroft> there will soon be a taco cart on every corner!
[13:39:19] <gregcnc> but there will be a robot behind it
[13:39:31] <roycroft> no, there will be a mexican behind it
[13:39:36] <roycroft> an ILLEGAL mexican
[13:39:41] <roycroft> serving us delicious tacos
[13:40:14] <Jymmm> drone taco delivery... WOOHOO
[13:40:28] <CaptHindsight> self driving/flying
[13:40:34] <gregcnc> so you're saying you want robot wall builders?
[13:40:50] <Jymmm> I'm saying I WANT TACOS!!!
[13:40:54] <gregcnc> pilots are in airplanes only to place blame at this point
[13:41:11] <Jymmm> gregcnc: and a peace of mind for the passangers
[13:41:25] <Jymmm> gregcnc: woould YOU get on a drone controlled plane?
[13:41:46] <CaptHindsight> well people really aren't necessary, there are too many already
[13:41:49] <gregcnc> compared to an intoxicated pilot who might have slept last night?
[13:42:06] <Jymmm> gregcnc: or one that flies into the hudson river
[13:42:22] <gregcnc> emergency is a problem
[13:42:29] <Jymmm> yep =)
[13:42:41] <CaptHindsight> what they really need is a way to extract all your wealth and resources right from birth, preferably earlier
[13:42:51] <Jymmm> lol
[13:43:21] <gregcnc> didn't previous generations do that already?
[13:43:48] <IchGucksLive> Gn8
[13:44:56] <CaptHindsight> gregcnc: but they lost control for a while
[13:45:45] <gregcnc> the key is to figure out how to trick them into giving it back to you for some menial tasks
[13:45:51] <CaptHindsight> you need enough people to feel the power of controlling them, what else is life about?
[13:50:07] <SpeedEvil> To crush your enemies, to see them driven before you, and to hear the lamentations of their women!
[13:50:40] <CaptHindsight> amen
[13:50:59] <CaptHindsight> the good ol days
[13:52:54] <CaptHindsight> lamentated women
[14:02:40] <Jymmm> veneer womens? No thanks
[14:04:09] <gregcnc> how do you know when to stop tapping with a NPT tap?
[14:05:13] <Jymmm> when the tap breaks?
[14:05:49] <gregcnc> next time I'll be more clear
[14:05:49] <SpeedEvil> just back off a quarter turn after it breaks
[14:06:13] <gregcnc> tapping NPT is strange
[14:06:49] <enleth> gregcnc: test fit the other part until it goes in deep enough, mark the depth on the tap
[14:07:30] <gregcnc> that's only half the tap length it seems
[14:13:10] <enleth> gregcnc: well, you could tap a very deep thread, then cut a very long outside thread on a section of pipe or whatever and use that
[14:13:50] <gregcnc> If it was important I suppose there are gages for this.
[14:16:51] <Jymmm> gregcnc: Since you know the depth it should be, and threads are in "TPI", could you give an estimate and take off 10% ?
[14:19:58] <Jymmm> gregcnc: as a baseline that is
[14:35:32] <Crom> dang it.. missing my 4mm collet... just ordered on for $1.79
[14:35:36] <Crom> one
[14:37:37] <Crom> I do have my 3mm collet so once the 3 and 4mm endmills show up I can use the 3mm
[14:40:46] <CaptHindsight> who stocks continuous duty cycle rotary solenoids? ~24V, 90 deg, <1in/lb
[14:41:33] <CaptHindsight> http://www.newark.com/ledex/h-2414-029/solenoid-rotary-continuous/dp/20M1287 $90 just seems high

[14:45:50] <Jymmm> 1.5
[14:45:58] <CaptHindsight> mid-grade
[14:57:49] <Jymmm> CaptHindsight: ghetto grade
[15:00:35] <CaptHindsight> guaranteed to arrive, no returns
[15:29:36] <Jymmm> to arrived damage?
[16:06:01] <CaptHindsight> Jymmm: parts so old new stock that the part numbers have been forgotten
[16:12:30] <CaptHindsight> gregcnc: right down the road http://www.guardian-electric.com/careers.html
[16:16:07] <Crom> just ordered 5 more 3mm 3x3x9x75 2 flute carbide endmills $27
[16:17:25] <gregcnc> capthindsight driven by there so many times never even knew they were there
[16:19:42] <CaptHindsight> same here
[16:21:04] <CaptHindsight> gregcnc: ever use Dura-Bar?
[16:21:22] <gregcnc> yes I picked up 100lb this summer
[16:21:41] <CaptHindsight> do they sell direct?
[16:25:17] <Jymmm> YAY! Taxes are done
[16:25:37] <Jymmm> Well, as soon as I mail em that is
[16:26:32] <gregcnc> they have a minimum order of $100 way cheap my order was $1/Lb
[16:27:05] <gregcnc> any distributor was twice that
[16:28:34] <gregcnc> i found this place today if you need ground plate steel www.flatground.com in elgin but it seems Mcmaster is just a few bucks more. probably sourced there
[16:35:53] <CaptHindsight> nice, was looking at space down the street from there
[16:42:19] <Crom> this is promising... http://www.shapeoko.com/forum/viewtopic.php?f=30&t=6311
[16:51:16] <gregcnc> If you're using Linuxcnc do you need the arduino?
[16:51:52] <Crom> yep... you can read the pwm from linuxcnc, and have it be the base for your rpm...
[16:52:21] <Crom> the nano regulates the pwm going into the speed control to maintain the RPM
[16:53:54] <CaptHindsight> or http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Closed_Loop_Spindle_Speed_Control
[16:53:58] <gregcnc> you read the index signal to get RPM.
[16:54:33] <Crom> my machine is slow enough... I can off load rpm monitoring to the arduino
[16:55:24] <CaptHindsight> has anyone done this with fishing weights and a webcam?
[16:56:36] <CaptHindsight> the fishing weights are mounted on arms with springs that counteract the centrifugal forces of the weights as they spin
[16:57:25] <CaptHindsight> the higher the rpm the higher the weights spin, the camera measures the height of the rotation and outputs the pwm to the motor

[17:27:35] <Frank_2> hello guys, it has been some time since last time
[17:27:43] <Frank_2> (not comming to bother ya) heh
[17:45:46] <CNCdrew> help
[17:45:52] <CNCdrew> oops. Sorry
[17:46:52] <CNCdrew> I am converting a machine from mach3/smoothstepper to LinnuxCNC
[17:46:59] <JT-Shop> hi Frank_2
[17:47:37] <CNCdrew> I am nearly done (thanks to all ) but am seeing less than desired speeds on my motors
[17:47:53] <CNCdrew> the old machine was configured for 8th stepping
[17:48:22] <CNCdrew> but I am seeing that I cant get much speed/velocity/acceleration without skipping steps.
[17:48:51] <CNCdrew> would modifying the machine to use half steps increase my potential speed
[17:49:32] <JT-Shop> depends on what it is now
[17:50:19] <CNCdrew> its 8th stepping
[17:50:28] <JT-Shop> yes
[17:52:19] <CNCdrew> would you advise that approach?
[17:53:44] <CNCdrew> It doesnt use ball screws (on X and Y) but a gear and keyway setup. so 1 turn of the motor travels over 4 inches
[17:53:59] <JT-Shop> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Stepper_Motor_Speed_Limitations
[17:54:14] <JT-Shop> try to figure out the maximum rpm you can spin the stepper
[17:54:27] <JT-Shop> http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Stepper_Formulas
[17:55:09] <andypugh> CNCdrew: Was it faster with Mach3?
[17:55:50] <CNCdrew> it was faster with mach3
[17:56:15] <CNCdrew> it is setup simmilar to this.
[17:56:16] <CNCdrew> http://static1.1.sqspcdn.com/static/p/408937/4119421/1262809601917/Arty+3.jpg?asGalleryImage=true&token=UERWxbyfkqYRDV49CFhjhhfLHDI%3D
[17:57:37] <CNCdrew> where one turn of the stepper moves the axis about 4 inches. It also seems to 'slip' easily if pushing against it while configuring the axis in stepconf
[17:57:42] <andypugh> If it was faster with Mach3+smoothstepper and now you are using LinuxCNC + Parport (?) then the problem might well be insufficient step rate.
[17:58:14] <andypugh> Though you probably need to be sure that the step length / step space are the same as before too.
[17:59:01] <CNCdrew> how do I make sure step length / space are same as before?
[17:59:04] <andypugh> If you _only_ changed the software and stil have the same motors, drives, and other hardware, that is.
[17:59:17] <andypugh> CNCdrew: You would use the same settings.
[17:59:57] <andypugh> How did you create the config? Was it by importing the Mach3 XML file into LinuxCNC Stepconf?
[18:02:11] <CNCdrew> I didn't import the mach3 XMX file - partly because there wers some issues on the old machine (probe/home switch problems)
[18:03:42] <CNCdrew> I just created a new setup in stepconf - used the defaults for my keling 4030 and tried to setup from scratch.
[18:04:27] <CNCdrew> but I could try to import the XML and see what I get.
[18:05:59] <CNCdrew> would you advise I try to change the microstepping setting?
[18:08:40] <CNCdrew> I read the page: http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Stepper_Motor_Speed_Limitations
[18:10:14] <CNCdrew> Most was above my head. :)
[18:10:52] <CNCdrew> andypugh: thanks for the suggestions. I will try to import the mach XML and see what I get
[18:12:05] <CaptHindsight> CNCdrew: post your current config.ini
[18:13:05] <CaptHindsight> 1 turn = 4 inches. How many steps per rev on those motors? Are you using 1/8 microstepping?
[18:13:24] <CNCdrew> I am not at the shop pooter now. Will post the config.ini this evening
[18:14:25] <CaptHindsight> 200 steps per rev?
[18:15:30] <CNCdrew> yes. 200 steps per rev
[18:16:00] <andypugh> CNCdrew: What did your base-period end up as, and how does that compare to step-rate at max speed?
[18:16:15] <CNCdrew> yes. Its setup for 8th stepping. Wondering if that should change
[18:16:33] <andypugh> We haven’t enough information yet to say.
[18:16:41] <CaptHindsight> when you command it to move 1cm or 1" is that the movement you measure?
[18:16:42] <CNCdrew> base-period was under 8000
[18:17:12] <CNCdrew> how do I determine step-rate at max speed
[18:17:35] <andypugh> STEP_SCALE x MAX_VELOCITY
[18:18:23] <AndChat|234416> hey hey
[18:19:00] <AndChat|234416> ;)
[18:19:34] <CaptHindsight> CNCdrew: JT-Shop posted the links to the relevant docs with the formulas
[18:19:49] <CNCdrew> thanks
[18:20:23] <andypugh> CNCdrew: You will fnd those two parameters in the INI file you have created
[18:20:39] <MacGalempsy-> :) hello
[18:26:06] <JT-Shop> andypugh: did you sort out your gkt question?
[18:30:54] <FloppyDisk525> I just don't see how they use Hiwin rails and a price of $199 and make money? https://www.kickstarter.com/projects/854865943/cetus3d-at-199-get-all-you-need-to-start-3d-printi/?3ders
[18:31:20] <FloppyDisk525> Plus steppers, plus controller, plus assembly? So cheap, I'm missing something...
[18:32:51] <Kevin`> cheap clone linear rails aren't TOO espensive, and they are using them in place of frames
[18:33:20] <Kevin`> I don't see anything groundbreaking there though
[18:33:28] <Kevin`> IMO wait to see if the company suceeds
[18:33:37] <Kevin`> $200 may not be enough for profit
[18:33:57] <Kevin`> there's plenty of similar printers you can buy right now without pre-ordering
[18:34:37] <Kevin`> I like that minimalist design though
[18:40:28] <FloppyDisk525> minimalist design is nice, some of the marketing further down is nice as well... Selling the 'what you can do w/ it'
[18:44:11] <andypugh> JT-Shop: Not elegantly.
[18:44:31] * JT-Shop is just wrapping up assembling this one https://www.aliexpress.com/item/Full-Metal-Frame-3D-Printer-Professional-3d-Color-Printer-with-8GB-SD-Card-LCD-One-Roll/32705186296.html?spm=2114.13010608.0.0.RAhBEI
[18:44:52] <JT-Shop> I saw some stuff about the builder iirc
[18:45:42] <malcom2073> JT-Shop: What do you think about it?
[18:45:54] <malcom2073> I was eyeing that one up, rather than spending the $200 to get my other printer running again heh
[18:46:41] <andypugh> JT-Shop: My problem has been making the layout re-sizable.
[18:46:50] <JT-Shop> well, the printed parts are printed, the injection parts are good, the water jet cut acrylic parts are really good
[18:47:18] <andypugh> I have ended up saving the original position of every element then re-calculating where they need to be
[18:47:20] <malcom2073> How are the linear parts? Screws pretty straight, and bearings smooth?
[18:47:55] <JT-Shop> the linear bearings are a bit noisy imho but lets see after a print
[18:48:24] <JT-Shop> gtk should just resize when you resize the window
[18:48:58] <andypugh> JT-Shop: Not with a gtkFixed container
[18:49:45] <andypugh> I could probably re-parent every element with an Alignment.
[18:50:06] <andypugh> But that’s a lot of work.
[18:50:18] <JT-Shop> I've not used a gtkFixed container
[18:50:26] <JT-Shop> are you using Glade?
[18:50:36] <andypugh> Yes
[18:51:10] <andypugh> And that’s a problem in itself, as it’s really hard to select the thing you want when there is an image filling the window
[18:51:36] <JT-Shop> do you have a copy of what your doing online?
[18:52:21] <andypugh> complete config here: https://forum.linuxcnc.org/forum/41-guis/26550-lathe-macros
[18:53:22] <andypugh> The game is to make it re-size and leave the numbers where they belong.
[18:54:20] <JT-Shop> just looking at the first post the numbers that point to the image?
[19:09:44] <andypugh> Maybe.
[19:09:59] <andypugh> Not quite sure if we are on the same wavelength?
[19:10:24] <andypugh> The first post is the latest version.
[19:11:01] <andypugh> (Well, not the version I am working on recently, but the one that worked)
[19:14:32] <FloppyDisk525> JT-Shop - are you planning on running that 3d printer w/ linuxcnc or the merlin (or whatever comes w/ it). For the price, you can't hardly beat it...
[19:17:05] <CaptHindsight> andypugh: any thoughts on what interface you would start with if you wanted to see SVG slices in a window like Axis
[19:17:45] <andypugh> I have actually don that....
[19:17:51] <CaptHindsight> would you start with AXIS, Gmoccapy etc?
[19:18:25] <andypugh> I would probably start from scratch, assuming that it’s for a DLP so it won’t need G-code
[19:19:14] <CaptHindsight> well lets not remove g-code since the printer might be doing more than just moving the Z while projecting an image
[19:19:38] <andypugh> Have you seen https://www.youtube.com/watch?v=ChKmIHP7G_U ?
[19:19:41] <CaptHindsight> thats the corner the reprapists get themselves into
[19:20:45] <CaptHindsight> didn't see that until now
[19:21:56] <andypugh> I am trying to send you the files in anoter window. But I don’t think it is working
[19:22:10] <CaptHindsight> heh, nope, never has
[19:24:20] <Kevin`> CaptHindsight: corner?
[19:25:13] <Frank_2> andy, to help me remember which was your method of removing rust by soaking in ***** for a long period of time?
[19:25:15] <CaptHindsight> Kevin`: not leaving it general purpose and not keeping it flexible, not being aware of what they really need to do
[19:25:25] <Frank_2> ops enter before writing
[19:25:44] <CaptHindsight> reinventing the wheel
[19:25:46] <Frank_2> could you please help me remember ... bla bla.. hehe please?
[19:26:14] <Frank_2> something with enzymes was
[19:26:22] <Kevin`> CaptHindsight: in what way, using limited processing power for machine control? most reprap machines use pretty standard g-code control
[19:26:29] <CaptHindsight> coming up with things like marlin and printrun, pronterface etc
[19:27:11] <malcom2073> Frank_2: evaporust is amazing
[19:27:43] <Frank_2> malcom2073: i dont think i have that brand in my country
[19:27:49] <andypugh> Frank_2: Molasses
[19:27:50] <Frank_2> i was going to soak in vinegar...
[19:27:53] <Frank_2> that!
[19:28:20] <andypugh> Molasses 10:1 with water
[19:28:30] <Frank_2> thanks, ill google to get some more info, i knew that really worked
[19:28:35] <Frank_2> :D
[19:28:40] <CaptHindsight> andypugh: ah, I think I have a copy of that from you from last year
[19:45:02] <andypugh> Anyway, time to sleep.
[19:49:54] <CaptHindsight> Frank_2: have you tried naval jelly?
[19:51:24] <Frank_2> capt! i dont think i have that here
[19:52:22] <Frank_2> thats why i asked about the molasses, they are everywhere :D
[19:52:37] <Frank_2> i will just soak everything and let it work for a week or more
[19:52:51] <CaptHindsight> Coca Cola
[19:55:09] <Frank_2> thats cheap
[19:55:31] <CaptHindsight> try both
[19:55:32] <Frank_2> mollases 250ml 10$
[19:58:28] <roycroft> better to try to convert the rust via electrolysis first, before eating it away
[19:58:56] <CaptHindsight> roycroft: he seems to have very limited resources
[19:59:33] <roycroft> electrolysis requires a battery, some wire, a piece of steel, a plastic tub/bucket, and some kind of salt
[19:59:38] <CaptHindsight> molasses and Coke seems to be available
[19:59:40] <roycroft> alligator clips help
[20:00:16] <CaptHindsight> https://www.youtube.com/watch?v=d9-CnodnzDQ Does Coca Cola work as a de-rust?
[20:01:25] <Jymmm> CaptHindsight: white vinegar does for sure
[20:02:10] <Jymmm> Frank_2: a week?! vinegar takes just one day
[20:02:23] <Jymmm> and removes laytex paint too
[20:02:27] <CaptHindsight> we need a volunteer to side by side use them and make a youtube
[20:03:05] <roycroft> has beachbumpete been around lately?
[20:03:08] <Frank_2> really? one day? its *really* rusty
[20:03:11] <Jymmm> dont need a cide by side, I've removed a lot of rust lately using vine]gar that I now keep a soaking jar handy
[20:03:16] <roycroft> i wonder how he's faring with a major hurricane headed his way
[20:03:21] <CaptHindsight> roycroft: several times a week
[20:03:37] <roycroft> it looks like carolina will get the brunt of it
[20:03:46] <roycroft> but florida is going to see some pretty nasty weather
[20:03:48] <CaptHindsight> he did not seem too concerned yet
[20:04:04] <roycroft> is he on the gulf side or the ocean side?
[20:04:05] * roycroft forgets
[20:04:15] <Jymmm> Frank_2: Well, 16 hours. Then I take a wire brush to it, and go for another soak if there is any remaining.
[20:04:19] <CaptHindsight> it was the night before it landed on Haiti
[20:04:25] <CaptHindsight> ocean side
[20:04:37] <roycroft> then friday will be an exciting day for him for sure
[20:04:39] <Frank_2> the price of vinegar seduces me lol
[20:06:05] <CaptHindsight> should we play chemist and compare vinegar (acetic acid + water) to Coke (Phosphoric acid + water)?
[20:06:06] <Jymmm> Frank_2: I just had a steel garage door trim that I found rusting out at the bottom. took it down to bare metal using vinegar and it removed the paint all at the same time. Then used oil based enamel paint.
[20:07:29] <roycroft> coke also has a lot of carbonic acid
[20:07:48] <Jymmm> As a first thought... what would make a motion light not turn on, but stil senses motion?
[20:08:06] <CaptHindsight> bad lamp
[20:08:20] <Jymmm> I have it disconnected and sitting in frot of me
[20:08:27] <CaptHindsight> bad lamp driver/switch
[20:08:29] <Jymmm> there are two bulbs.
[20:08:50] <Jymmm> the led blinks as I move in front of it.
[20:09:17] <Jymmm> and it did (not any longer) go back to normal if I unplugged it for 5 minutes.
[20:10:01] <roycroft> all three are weak acids, but iirc acetic acid is the weakes of the three
[20:10:12] <roycroft> weakest
[20:10:39] <CaptHindsight> concentration is different
[20:11:24] <roycroft> i'm talking about same molarity
[20:11:29] <CaptHindsight> vinegar has maybe 8-10% acid
[20:11:40] <roycroft> you can adjust molarity by diluting the acid
[20:12:01] <roycroft> but iirc, phosphoric acid is the strongest of the three, and acetic acid the weakest
[20:12:33] <kyle___> heh, that 15 ton injection molder in santa clara ended up selling for $460
[20:13:08] <nubcake> night everyone
[20:16:08] <CaptHindsight> distilled Diet Coke
[20:17:02] <kyle___> wouldn't that be water...?
[20:17:21] <CaptHindsight> depends on what you save
[20:19:31] <CaptHindsight> Diet Coke reduction
[20:20:01] <roycroft> waterish
[20:20:10] <gregcnc> tannic acid does OK
[20:20:30] * roycroft still votes for electrolysis first
[20:20:43] <roycroft> once you remove the metal it's very difficult to put it back
[20:20:46] <CaptHindsight> Frank_2: do you have the materials?
[20:21:03] <CaptHindsight> or access to them for electrolysis?
[20:21:10] <Frank_2> ups was absent srry let me read
[20:21:55] <roycroft> calcium carbonate makes an excellent salt for electrolysis
[20:22:01] <CaptHindsight> https://www.youtube.com/watch?v=y4yYF8gSHdA Rust removal by Electrolysis
[20:22:06] <roycroft> but sodium bicarbonate (baking soda) also works well
[20:22:39] <Frank_2> the materials?? steel
[20:22:47] <Frank_2> i dont have a car battery charger
[20:22:55] <roycroft> you can use a battery
[20:23:08] <roycroft> i don't know how big this piece is that you need to convert/derust
[20:23:24] <CaptHindsight> http://www.instructables.com/id/Electrolytic-Rust-Removal-aka-Magic/
[20:23:27] <roycroft> but if it's small even a 9v battery will do
[20:23:53] <Frank_2> its like a C channel but 2'' x 2'' x 1/4''
[20:24:01] <Frank_2> 1 meter
[20:24:02] <roycroft> that's pretty small
[20:24:03] <Frank_2> aprox
[20:24:04] <Frank_2> 3 feet
[20:24:05] <roycroft> oh
[20:24:06] <gregcnc> a 2.5kW lab supply works too
[20:24:07] <roycroft> not so small
[20:24:08] <Frank_2> hehe
[20:24:25] <Frank_2> 220v ac doesnt?? :D
[20:25:13] <gregcnc> just don't try to light the bubbles that form on top.....
[20:25:39] <CaptHindsight> https://www.youtube.com/watch?v=CLaBFkeHG0A waiting for Walmart to carry these :)

[20:32:42] <gregcnc> http://www.skyfirecnc.com/picshow.asp?id=36 linuxcnc/mesa in the works. starting at only 1$
[20:33:14] <gregcnc> these guys really seem to be making a fair effort
[20:36:21] <MacGalempsy_> got the drum and refractory figured out https://flic.kr/p/MrH8bS
[20:36:48] <MacGalempsy_> the drum gets cut down to 20" and it takes 10gln of refractory cmnt
[20:37:59] <MacGalempsy_> the base and top are 4" thick and the center has 3" walls
[20:38:16] <MacGalempsy_> 8"x12" chamber
[20:38:57] <gregcnc> bbq aluminum fro dinner this weekend?
[20:40:11] <MacGalempsy> maybe the following weekend. the drying process takes about a week
[20:40:24] <MacGalempsy> then the curring process is another day or two
[20:40:41] <MacGalempsy> gregcnc: you bring the aluminum
[20:41:28] <gregcnc> I have a 50lb of Mic6 here but doesn't need recasting
[20:42:36] <MacGalempsy> my buddies are coming over and we are going to make 2 this weekend and a third horizontal unit for a knife making setup
[20:43:09] <CaptHindsight> gregcnc: I think operate from a secret moonbase
[20:43:15] <MacGalempsy> drum $8. cement $50 (for all 3),
[20:43:23] <gregcnc> fuel?
[20:43:35] <MacGalempsy> propane for the first iteration
[20:43:42] <CaptHindsight> gregcnc: can you find an actual address?
[20:43:42] <MacGalempsy> propane and a blower
[20:44:03] <gregcnc> there is a US source
[20:49:06] <CaptHindsight> gregcnc: didn't find an address here either http://www.skyfirecnc-usa.com/index.html
[20:49:30] <CaptHindsight> just Decatur, Alabama
[20:53:10] <gregcnc> hmm no phone number is troublesome. The guy in china had a thread on cnczone on the build of the first few machines.

[20:56:19] <CaptHindsight> they are not too far from the airport
[20:56:27] <CaptHindsight> it's industrial around there
[21:00:04] <CaptHindsight> I was wondering when somebody there was going to offer Linuxcnc
[21:02:24] <CaptHindsight> heh, that thread is about it being a possible scam
[21:03:01] <gregcnc> oh I haven't looked at it in years
[21:03:30] <zeeshan> nice
[21:03:33] <zeeshan> all those machines are $1
[21:03:36] <zeeshan> need to order a few
[21:04:23] <zeeshan> man
[21:04:27] <gregcnc> it's a lot of effort to scam money from machinists
[21:04:30] <zeeshan> i've been using hsm for inventor
[21:04:36] <gregcnc> wannabemachinists
[21:04:44] <zeeshan> theres a bunch of features in it that im suprised mastercam is so shit at
[21:05:41] <zeeshan> the "similar holes" feature is awesome in hsm!!!!!!!!!
[21:05:57] <zeeshan> it automatically picks up hole top and hole bottom
[21:06:10] <zeeshan> but it lacks in the customization of tool paths
[21:06:11] <zeeshan> =/
[21:06:47] <CaptHindsight> the problem is designing a machine that aligns itself
[21:07:17] <zeeshan> aligns itself?
[21:07:21] <CaptHindsight> you can't get labor there that would know how to do it properly without training them
[21:07:48] <CaptHindsight> zeeshan: yes, when assembled
[21:14:31] <CaptHindsight> it will be the same way here (usa) soon
[21:14:47] <CaptHindsight> skilled handy people are getting old
[21:36:07] <Crom> just epoxied 3 neodynium magnets into my spindle fan. Now to find a halleffect sensor
[21:48:36] <Erant> Hmmm. Has anyone ever written an auto-backlash detection module? I just realized that given my servo drives (and really any servo system) that should be doable. Reverse the screw until you're sure you've taken up any backlash, then slowly move forward until there's an increase in torque. (from you actually moving the table).
[21:50:30] <cradek> I have measured it directly by mounting a glass scale on the table and sending both encoder feedbacks to halscope
[21:50:50] <cradek> from that you could directly make a precise screw compensation table
[21:51:04] <cradek> I would not try to guess from servo current or similar, when I can measure directly
[21:51:46] <cradek> http://timeguy.com/cradek-files/emc/no-backlash.png
[21:51:53] <cradek> look I still even have the plot, wow
[21:56:14] <zeeshan> CaptHindsight: i doubt it
[21:56:27] <zeeshan> our companys manufacturing facility has some fairly young guys
[21:56:41] <zeeshan> and they're some of the best fabricators/machine builders/machinists i've come across
[21:57:39] <zeeshan> nice cradek
[21:57:47] <zeeshan> i'd be interested to see what it looks like under a cut
[22:06:23] <cradek> zeeshan: yes it seems like a lot of things could show up when cutting that aren't reflected in that plot
[22:06:46] <cradek> and you could totally measure those too! like how much ballnut preload is enough?
[22:07:17] <cradek> you can see my resolvers had a LOT more resolution than the scale
[22:18:57] <MacGalempsy_> http://www.industrydepot.com/store/product.php?productid=20522&cat=573&page=1
[22:19:20] <MacGalempsy_> wow. if we can pour the mast, then the rest is pretty cheap
[22:27:40] <BeachBumPete> jeez man cutting the hurricane shutter material they gave me for the house when we bought it was kind of a Beotch! LOL
[22:33:08] <MacGalempsy_> you all shuttered up?
[22:33:48] <BeachBumPete> not yet but we have everything cut to length. Will be waking up tomorrow morning and getting them installed.
[22:35:37] <MacGalempsy_> sounds like the party has already started!
[22:36:51] <roycroft> you have until friday noon
[22:37:07] <roycroft> i would not wait until the last minute though :)
[22:37:34] <BeachBumPete> no we don't we are execting to start feeling the effects and seeing the feeder bands by Thursday morning apparently
[22:38:58] <cncDrew> any tips for tuning accuracy?
[22:39:04] <MacGalempsy_> just enough time to board up and take a flight out of town
[22:39:24] <BeachBumPete> Oh we are not leaving
[22:39:35] <cncDrew> I was fairly sure I had the config correct - but when I say to move 1 inch - it is off a bit
[22:40:16] <MacGalempsy> steppers?
[22:40:22] <cncDrew> yes.
[22:40:41] <MacGalempsy> i must defer, I only have used servos
[22:41:12] <cncDrew> cool. Some day I will try that :)
[22:42:01] <roycroft> yes, it is a pretty big storm
[22:42:17] <roycroft> and it's moving really really slowly
[22:42:39] <roycroft> i can see it starting to arrive thursday morning and sticking around until saturday night
[22:42:57] <roycroft> iirc it is moving north at 6kt
[22:43:02] <roycroft> which is pretty damn slow
[22:43:11] <MacGalempsy> they evacuted most ppl from gitmo, I wonder if they make the terrorists stick around?
[22:43:20] <MacGalempsy> (if there are any left)
[22:43:20] <BeachBumPete> yeah it is kinda slow moving right now
[22:43:26] <roycroft> you mean the detainees?
[22:43:56] <roycroft> since none of them have had a trial, none of them are proven terrorists at this point
[22:44:05] <BeachBumPete> I have been to Gitmo several times
[22:44:33] <MacGalempsy> pleasure or incarceration?
[22:44:35] <roycroft> there's a whole bunch of houses there
[22:44:41] <roycroft> and a little town
[22:44:51] <roycroft> is that just for the military, or can civilians live there too?
[22:45:26] <BeachBumPete> I was there for Reftra twice and a few times we towed vessels that needed to be inspected by the DEA or other agencies there
[22:46:13] <BeachBumPete> there is some impressive diving on the leeward side along the cliffs
[22:46:31] <roycroft> geographically it's a pretty interesting place
[22:46:50] <roycroft> i've not been there, but i'm familiar with the topology
[22:47:38] <BeachBumPete> there were some really cool very purple octopi we saw there that glowed in the dark I used to have some pictures of them but I have no idea where they went to.
[22:47:53] <roycroft> turn the lights off
[22:47:56] <roycroft> and look for the glow
[22:48:24] <BeachBumPete> or rather they glowed very brightly in the light of the dive lights we used.
[22:49:10] <BeachBumPete> not sure they they actually glowed in the dark
[22:50:11] <MacGalempsy> Pete, have you noticed supermarkets running out of food yet?
[22:50:21] <BeachBumPete> yes actually
[22:50:37] <MacGalempsy> what all did you stockup on?
[22:50:39] <BeachBumPete> we went after work to try to buy some food supplies and it was already pretty picked over
[22:50:53] <BeachBumPete> we wanted the usual bread milk water cold cuts etc.
[22:51:37] <BeachBumPete> there was not much bread left
[22:51:38] <BeachBumPete> the meats were running low
[22:51:44] <BeachBumPete> then I went to Home Despot to buy the fasteners for the hurricane shutters and they were nearly all out.
[22:52:41] <MacGalempsy> i bet most of those places are not going to restock until the area is clear
[22:52:58] <MacGalempsy> any fast food places closed up?
[22:53:04] <BeachBumPete> no idea but we have enough stuff here now
[22:53:14] <roycroft> are the taco stands on every corner closing up?
[22:53:24] <BeachBumPete> no nothing really closed up. My work is closed tomorrow and thursday
[22:53:38] <BeachBumPete> what taco stands on every corner?
[22:53:54] <roycroft> i guess they're not all here yet
[22:54:05] <roycroft> but if clinton is elected that's what we'll have to endure
[22:54:07] <roycroft> yum!
[22:54:22] <BeachBumPete> there are a few taco trucks up in Fort Pierce that are really good tho
[22:55:07] <BeachBumPete> when we were living down in West Palm Beach there was a few Taco trucks and we used to go to one of them occasionally
[22:55:32] <roycroft> my experience is that they vary widely in quality
[22:55:32] <BeachBumPete> it was actually quite delicious!
[22:55:46] <BeachBumPete> but we only have taco bell and a few local mexican restaurants in this city
[22:55:51] <MacGalempsy> arent most of the latinos there de sur america?
[22:55:53] <BeachBumPete> Of that I have no doubt
[22:55:59] <roycroft> taco bell is not a restaurant
[22:56:04] <roycroft> because it does not serve food
[22:56:15] <BeachBumPete> I can't eat at Taco Bell
[22:56:20] <roycroft> cubans in south florida
[22:56:25] <BeachBumPete> but my kids love their taco
[22:56:31] <MacGalempsy> yeah, they dont really eat tacos like mexicans, right?
[22:56:34] <BeachBumPete> cubans make some good food
[22:57:04] <BeachBumPete> there is a cuban restaurant here we went to and it was really good. I cant remember the name right now
[22:57:05] <MacGalempsy> with their mouths yes, but the cuisine seems to be more traditional south american style
[22:58:14] * roycroft is actually enjoying one of the last mojitos of the year right now
[23:00:02] <MacGalempsy> mmmm. me gustaria uno mojito ahora
[23:00:34] <roycroft> mint starts dying back in late september here, sadly
[23:00:52] <roycroft> by week's end it will be mostly gone
[23:01:01] <roycroft> so no more mojitos until spring
[23:01:46] <roycroft> but soon it will be time to make glühwein
[23:02:37] <MacGalempsy> movie time guys. catch you all tomorrow!
[23:06:51] <Crom> got a 1/8" end mill with 1/4 shank 4 flute... gonna give it a whirl tomorrow
[23:07:46] <Crom> wish I had a windows machine to run fusion on... see if I could generate a slotting cut...
[23:37:41] <Erant> Crom: Aren't you still cutting aluminum?
[23:38:12] <Erant> A 4fl is going to get pretty clogged up. Been there, done that, ruined a really good cutter.
[23:40:47] <roycroft> gummy metals are tough to machine
[23:49:15] <Erant> I was actually about to order some 1/8" cutters. I want to try some 3 flute stubs.
[23:50:17] <Erant> If I can get the chips out, that's 1.5x the feed.
[23:50:39] <Erant> I have a 3/8" 3 flute rougher that I love, but not sure how that translates to smaller cutters...
[23:50:49] <Erant> Guess I'll find out.
