[01:23:47] <pink_vampire> any life here?
[01:24:19] <yasnak> yup
[01:24:32] <yasnak> all nighter
[01:24:36] <yasnak> stupid holidays
[01:24:39] <yasnak> and hurricanes
[01:34:28] <pink_vampire> here there is no hurricanes
[01:51:17] <Crom> Marco
[01:51:41] * Crom pokes pink_vampire
[01:51:56] <pink_vampire> ?
[01:52:10] <Crom> seeing if you were really
[01:52:19] <Crom> seeing if you were real
[01:52:33] <Crom> ala ghost busters
[01:52:45] <pink_vampire> omg O_o
[01:53:51] <pink_vampire> i need to find a solution for a door hing
[01:53:55] <Crom> well... gonna try the nano PWM generator tommorrow
[01:54:06] <Crom> what kind of door?
[01:55:16] <pink_vampire> cabinet door
[01:55:29] <pink_vampire> made out of wood
[01:55:36] <Crom> to replace a broken one?
[01:56:13] <Crom> you look at woodgears.ca hinges that his dad made at their cabins?
[01:56:33] <Crom> mat waddell how ever you spell it
[01:57:46] <pink_vampire> i can't see anything about hinges
[01:58:04] <Crom> I hung a baby gate using a 1x2 with notches in it with holes drilled into the ends to slip pins in.. bottom one I used gaff tape to keep it in
[01:58:21] <Crom> youtube hang on lemme get the link
[01:58:55] <pink_vampire> thanks
[02:00:26] * archivist points at local hardware store hinge department
[02:00:47] <Crom> switching computers... this one is tooo damn slow
[02:02:50] <Crom_> this one is mainly latches but he does have hinges in there https://www.youtube.com/watch?v=bE5t-yOg6R4
[02:04:14] <Crom_> this one is pretty much just hinges https://www.youtube.com/watch?v=t1H7lj1zN_A
[02:07:47] <pink_vampire> lets see
[02:33:52] <Crom_> geez praying mantis are mean! they don't care what size you are... They'll take you on! 2nd one to jump on me in the last month
[02:37:47] <Deejay> moin
[03:45:12] <yasnak> hey, not so much machining but i need a better backup solution
[03:46:21] <yasnak> running windows 2008 r2, about 1tb or so of total backup but could grow. to keep it simple i'm wondering if I could put a virtualized windows 7 computer on the server and backup the servers to it using a network share. then use backblaze on the windows 7 and back that share up. think it would work? lol
[03:47:23] <archivist> just install linux
[03:57:26] <JesusAlos> Hi dear
[03:57:33] <yasnak> lol
[03:57:40] <yasnak> if i could i would
[03:57:46] <yasnak> if people could just learn new things...
[03:57:47] <yasnak> :/
[03:58:36] <JesusAlos> I'm looking for a CAM software for generate gcode for control this tools kind
[03:58:37] <JesusAlos> http://donektools.com/product/d1-drag-knife/
[03:58:40] <yasnak> love when my boss gets new machines, new cad/cam software new controllers and i gotta learn it all in a day. but the upgrade from windows 7 to windows 10 nearly killed these guys. helpless people annoy me
[03:59:10] <yasnak> jesus, linuxcnc would do it...
[04:00:56] <LeelooMinai> JesusAlos: Fusion360 maybe? It is CAD + CAM + other things, like simulation
[04:02:04] <archivist> there is a difference for drag cutting which is a lift at corners
[04:02:05] <LeelooMinai> You can define cutting tools there, so probably no problem with that tool - not 100% sure though
[04:02:56] <LeelooMinai> Right, I see, this is a bit weird I guess
[04:04:42] <LeelooMinai> hey had discussion about this: http://forums.autodesk.com/t5/computer-aided-machining-cam/trailing-knife-addon/td-p/5503439
[04:04:46] <LeelooMinai> They*
[04:06:24] <JesusAlos> The idea is do the cutting and folding lines
[04:08:38] <JesusAlos> LeelooMinai: Autodesk solutions is a little expensive for my project
[04:09:14] <LeelooMinai> Fusion360 is free for non-commercial use and I think pretty cheap even for commercial use
[04:09:24] <JesusAlos> yasnak: There a script for linuxcnc?
[04:09:41] <JesusAlos> Oh
[04:09:51] <JesusAlos> So I'll try
[04:10:56] <pink_vampire> http://donektools.com/
[04:11:13] <pink_vampire> very interesting
[04:11:26] <pink_vampire> http://donektools.com/wp-content/uploads/2012/07/knife-in-router2.jpg
[05:27:04] <jthornton> morning
[05:32:47] <unfies> o/
[05:39:35] <_methods> weee tropical storm
[05:47:14] <yasnak> haha, we're finally seeing the end of it
[05:59:10] <_methods> we're just getting the first bands now
[05:59:20] <_methods> not too bad so far
[05:59:46] <_methods> seems to be moving pretty fast so flooding won't be that bad i guess
[06:02:30] <unfy^work> rainsssssssssssss
[06:02:47] <unfy^work> i'd say i was jealous, but we're getting rain here in omaha, ne, usa :D
[06:03:13] <jthornton> no rain here for the next 4 days yea
[06:03:22] <XXCoder> here is very much definitely fall style weather
[06:03:36] <XXCoder> though it will bounce back a little for a week or so, then fall on from that
[06:05:40] <unfy^work> btw. a-fib sucks. hate it so much. *rage*
[06:05:47] <unfy^work> (atrial fibrillation)
[06:05:55] <_methods> supposed to be all sunshine once this swirly cloud thingy goes by
[06:06:13] <unfy^work> usually is, actually
[06:06:32] <unfy^work> if it's still got an eye wall and it passes over you, i'd suggest going outside and taking a look around. 'tis neat.
[06:06:39] <unfy^work> (have played in 3 or 4 hurricanes, personally)
[06:07:13] <_methods> a-fib thats not a good thing
[06:07:26] <_methods> you have a pace maker?
[06:07:39] <unfy^work> you can see pictures of eyewalls and stuff online, and videos, but like many things it just doesn't show the sheer beauty / scope of it
[06:08:03] <unfy^work> nah, lone a-fib (no other factors), and only recently has it gotten bad enough to warrant my attention.
[06:08:34] <_methods> you on meds?
[06:08:48] <unfy^work> i workout every day, been quit nicotine for 3 years, am late 30's, etc etc etc
[06:09:18] <unfy^work> not right now, cardiologist and I were both of the "lets wait and see" after the holter monitor figured out what it was... symptoms were going away / calming down etc
[06:09:38] <_methods> man that sucks
[06:10:29] <unfy^work> but, this week had another 45min fast paced episode that had me sitting in ER lobby just in case it got worse. then had trouble sleeping, and then was completely wrecked the next day (subconsciously tensing up, or just lots of adrenaline)
[06:10:52] <_methods> yeah sounds like a nasty feedback loop
[06:11:03] <_methods> anxiety about heart causes heart problem lol
[06:11:08] <unfy^work> yeah :D
[06:11:25] <unfy^work> since I know what it is, I consciously try to not worry about it
[06:11:34] <unfy^work> afib in of itself won't kill you etc heh
[06:12:36] <unfy^work> today (friday), might get to talk to cardiologist about stuff. i am fine with staying off meds 24/7 right now - as long as there are options for "recovery" after a bad episode
[06:13:32] <_methods> well you don't sound like a lifestyle change is going to fix it
[06:13:35] <unfy^work> can i take a xanax to calm me mentally ? and maybe... something else for physical stuff ? and then be fine ? cause if so - i'll take those once every 6-8 weeks instead of 24/7 meds
[06:13:40] <_methods> if you work out everyday and you're that young
[06:14:04] <unfy^work> i've seen something suggesting super dosing fishoil / omega-3 might help - i'll be asking about that as well
[06:14:22] <unfy^work> well... lifestyle change that would help ? de-stressing. looking around office.... *cough*
[06:14:35] <_methods> yeah i guess that would be one change
[06:14:39] <unfy^work> work is stupidly stressful. one reason why i'm leaving early next year :D
[06:14:47] <unfy^work> moving to TN \o/
[06:14:51] <_methods> but it's pretty hard to go through life without finding any stressors
[06:15:47] <unfy^work> with gym and hobbies and being a normally chill guy -- i can handle most stress :D this job has become too much after 16 years tho
[06:16:30] <unfy^work> sadly, i've not had much time to work on the hardware store CNC :(
[06:16:42] <unfy^work> still need to re-do the Z axis stuff, but just haven't had time
[06:17:06] <_methods> pretty sure health/body trumps cnc projects :)
[06:17:18] <unfy^work> cnc project is hobby which is relaxing (mostly)
[06:19:36] <unfy^work> here at work, boss did pick up a chinese 100-something watt laser cutter
[06:19:47] <unfy^work> was interesting to get to poke around it and see how it does things.
[06:20:18] <XXCoder> 100w?
[06:20:25] <XXCoder> what can it do, cut paper or?
[06:20:37] <unfy^work> it's primarily timing belt driven / moved which I still find weird
[06:20:46] <CaptHindsight> do all the ChinaCo laser cutters use glass tubes vs RF?
[06:20:53] <unfy^work> i know it can do 1/8 plexi. maybe thicker, not sure
[06:21:13] <unfy^work> i'm not the guy playing with it :(
[06:21:30] <unfy^work> it's a glass tube, just a CO2 laser iirc
[06:21:59] <unfy^work> think the guy was cutting some 1/4 plywood
[06:22:10] <_methods> yeah most of those 150w and lower are glass tubes
[06:22:20] <unfy^work> which is a bit fucked up given that we have an 8'x4' cnc router...
[06:22:38] <unfy^work> sorry, *shitty* 8x4 cnc router :P
[06:22:39] <_methods> yeah 1/4" plywood is probably about max for 100w
[06:23:07] <unfy^work> it'll be <150w, and >= 100w. not exactly sure what it was.
[06:23:38] <unfy^work> sadly, with how things work around here, they didn't get goggles for week(s) afterwards, and I'm not entirely sure they got the correct wavelength (facepalm)
[06:23:55] <XXCoder> unfy^work: im sure theres a way to test google
[06:24:04] <XXCoder> goggles
[06:24:14] <unfy^work> i'd assume a webcam
[06:24:33] <unfy^work> (much like webcam can see IR from remotes.... if it doesn't see anything through goggle, it is indeed blocking it?)
[06:24:50] <XXCoder> depends on freq range of laser and what cam can see
[06:24:56] <XXCoder> it must be within range
[06:25:45] <unfy^work> but - i kinda don't care too much. i nagged for many days about getting propper goggles, the boss finally ordered some (he never orders the right shit until the 4th time btw) ... so.... i've shut up about it and simply don't go near the room while it's powered up
[06:26:32] <enleth> unfy^work: those lasers are far infrared, completely different thing from IR remotes
[06:26:50] <enleth> unfy^work: no way you can see it with any garden variety imaging sensor
[06:26:53] <_methods> isn't the laser enclosed?
[06:27:09] <enleth> unfy^work: also, common silica glass blocks it completely
[06:27:09] <XXCoder> enleth: what would you use to test laser exposure?
[06:27:14] <unfy^work> methods: except for the clear plastic viewing area that takes about about 1/3 or 1/2 the area :D
[06:27:24] <enleth> unfy^work: so even normal eyeglasses will stop it
[06:27:40] <_methods> yeah i wouldn't worry too much
[06:27:42] <enleth> (they might get damaged, though)
[06:27:59] <enleth> basically, it's hard to find materials that *don't* block this wavelength range
[06:28:01] <unfy^work> enleth: really. i knew common glass would block IR stuff for say flir cams etc, didn't know they'd do same with most lasers
[06:28:02] <_methods> unless they're running it with the lid off
[06:28:18] <XXCoder> unfy^work: not most lasers. only deep IR
[06:28:23] <enleth> unfy^work: no, it's not "most lasers"
[06:28:23] <unfy^work> methods: i've seen what "safety" amounts in this building. i won't go near it :D
[06:28:27] <XXCoder> glass blocks deep ir
[06:28:30] <_methods> hahah
[06:28:42] <_methods> well i'll trust your judgement on that then
[06:28:50] <enleth> unfy^work: basically, the CO2 laser is more like a concentrated heat emanation than light
[06:28:59] <_methods> better safe than sorry......pirate style
[06:29:00] <XXCoder> I have seen near ir directly using my eyes. special googles (not powered but filters)
[06:29:02] <XXCoder> that was fun
[06:29:09] <XXCoder> everything looked... weird.
[06:29:16] <unfy^work> i had pics of what the tool room(s) looked like on local gun nut forum. everyone commented about OSHA and stuff, so I took the pics down to not cause waves :D
[06:29:34] <_methods> hahah
[06:29:54] <XXCoder> this method http://amasci.com/amateur/irgoggl.html
[06:30:56] <enleth> unfy^work: so the reason glass blocks FLIR's view is that a FLIR works in (more or less) the same far IR range as the CO2 lasers
[06:31:11] <unfy^work> enleth: what i was getting at
[06:31:20] <unfy^work> not realizing that, that is etc
[06:32:12] <enleth> unfy^work: oh, and the clear plastic window also blocks the beam completely
[06:32:27] <enleth> it might get burned through if something happens to reflect the beam properly
[06:32:32] <XXCoder> https://www.youtube.com/watch?v=ogRw4Htwvd0 enjoy. more or less what I saw
[06:32:40] <enleth> but you're going to see it being burned
[06:32:57] <enleth> also, it's not that easy to reflect the beam either
[06:33:46] <enleth> even a very well polished metal surface will get it completely out of focus when it hits the window
[06:34:13] <enleth> so it will start melting off a pretty big area, giving you plenty of time to back off and/or hit the red button
[06:34:32] <unfy^work> heh
[06:34:58] <enleth> the focal range is a couple centimeters from the lens, the window is like 20cm away
[06:35:25] <SpeedEvil> Also, your eyes cornea blocks CO2
[06:35:49] <SpeedEvil> this means that stray reflections are enormously less harmful (watt for watt) than visible.
[06:36:59] <enleth> well, yes, it's more likely to get a full recovery of an eye that got hit with a CO2 laser, even directly, because the retina is likely to be undamaged
[06:37:04] <SpeedEvil> A watt visible LASER hitting your pupil will cause major vision damage. A watt CO2 will not do much in comparison for glancing hits
[06:37:24] <XXCoder> I would wear googles period
[06:37:28] <XXCoder> one matching laser
[06:37:29] <SpeedEvil> True
[06:37:39] <XXCoder> I have only 3 senses (classical senses)
[06:37:41] <SpeedEvil> Or only operate in a light-tight box
[06:37:46] <unfy^work> indeed. eyesight too critical :D
[06:37:53] <XXCoder> so I am very much afraid of losing yet another
[06:37:55] <SpeedEvil> Light-tight box + internal cameras
[06:37:58] <SpeedEvil> cameras are cheap
[06:38:32] <enleth> XXCoder: normal machining goggles will be plenty enough for a small wattage CO2 laser then
[06:38:51] <XXCoder> co2 laser emits far IR?
[06:38:54] <SpeedEvil> XXCoder: yes
[06:38:59] <SpeedEvil> XXCoder: 10um, no visible light
[06:39:13] <SpeedEvil> Water starts to absorb 'all' light at ~1um.
[06:39:15] <enleth> a kilowatt CO2 laser is another story, but even then the "proper" laser grade goggles will be just a chunk of something thick that distributes heat very well
[06:39:20] <XXCoder> ok. if I ever get laser, I would completely enclose machine, use webcams
[06:39:23] <enleth> so you can see it getting melted before it burns through
[06:39:35] <CaptHindsight> CO2 is 10.6um wavelength
[06:40:00] <CaptHindsight> way above the visible spectrum
[06:40:03] <enleth> XXCoder: IMO a CO2 laser is the safest to work with as far as stray beam/reflection is concerned
[06:40:17] <XXCoder> interesting. ok
[06:40:22] <XXCoder> I always wanted a paper cutter
[06:40:22] <enleth> XXCoder: literally everything stops it, hardly anything reflects it well
[06:40:31] <XXCoder> cardboard, plastics. not much oast that
[06:40:36] <XXCoder> *past
[06:40:41] <enleth> XXCoder: so get yourself a 50W chinese laser
[06:40:54] <unfy^work> xxcoder: so far, they've had decent luck with the laser.
[06:41:09] <unfy^work> and i'm pretty happy with what i've seen them spit out of it
[06:41:13] <XXCoder> theres so many 500w cheap. :P (chinese 500w = 50w actual probablu though)
[06:41:21] <enleth> just word of warning: you'll likely want to gut the electrical enclosure and re-wire it from scratch
[06:41:28] <CaptHindsight> the fiber type marking lasers (YAG) are 1064nm (1.064um)
[06:41:59] <SpeedEvil> http://www.ebay.co.uk/itm/50W-Laser-Tube-for-CO2-Laser-Engraver-Hermetic-Glass-Tube-1-2kg-fast-shipping-/401028255362?hash=item5d5f258e82:g:2GYAAOSwIwhWSuq5 - amuses me
[06:42:04] <enleth> XXCoder: chinese tubes should be de-rated by 20 to 40%, AFAIR
[06:42:17] <XXCoder> I'll assume 90% lol
[06:42:19] <SpeedEvil> Specifically the fact that I can add a 3 year warranty from squaretrade for 14.99
[06:42:25] <enleth> XXCoder: a 500W chinese laser will get you 300W at least
[06:42:42] <XXCoder> heh so 50w can do paper cardboard and plastics?
[06:42:48] <enleth> plywood too
[06:43:01] <XXCoder> interesting I guess I was picturing it wrong before
[06:43:01] <CaptHindsight> just expect to have to change the tube in a few hundred hours of use
[06:43:01] <enleth> up to 5mm or so if you use proper plywood
[06:43:04] <SpeedEvil> 50w is verging into the 'serious cutter' territory
[06:43:15] <SpeedEvil> with proper extra stuff
[06:43:26] <XXCoder> what about those laser doides? (not tube)
[06:43:41] <SpeedEvil> Diode cutters can work just fine, but focusing them is annoying
[06:43:51] <CaptHindsight> RF laser tubes last 1k's of hours
[06:43:57] <CaptHindsight> but you pay more
[06:44:16] <enleth> XXCoder: I've been cutting 5mm wood, plywood and polymers just fine with a 50W tube, and it needs to be dialed all the way down to the lowest setting it still fires on to cut multi-layer corrugated cardboard without setting it on fire
[06:44:36] <SpeedEvil> you tend to generally need to take the output from the diode stacks, and put them into fibres (with little lenses) and then take the fibre bundle and form an image from the end of that
[06:45:07] <SpeedEvil> http://www.ebay.co.uk/itm/6W-NUBM44-450nm-Laser-Diode-In-Copper-Module-W-Leads-Glass-Lens-/171841778046?pt=LH_DefaultDomain_0&hash=item280291717e - though I have one of these I got cheapish to play with
[06:45:40] <unfy^work> heatsink it plz
[06:45:44] <pink_vampire> lasers a bit scared me,
[06:45:55] <SpeedEvil> unfy^work: yes, you will absolutely need a heatsink.
[06:46:21] <pink_vampire> even with the glasses 50W in to your face it's not fun
[06:46:28] <unfy^work> pink: and spinning hunks of metal @ 10's of k's of rip'ems do not ?
[06:46:29] <SpeedEvil> he also has the same thing mounted on a 20mm copper slug
[06:46:31] <XXCoder> ahh
[06:46:39] <XXCoder> laser diodes are like 500mW
[06:46:49] <XXCoder> not much power compared to co2 tube for example
[06:46:50] <SpeedEvil> XXCoder: Well - no.
[06:47:02] <SpeedEvil> XXCoder: the above is 6W. And you can get very powerful diode array
[06:47:11] <XXCoder> looking
[06:47:24] <XXCoder> how long do diode last
[06:47:32] <CaptHindsight> you can get a cheap 445nm laser setup https://www.youtube.com/watch?v=gF4HG6v29UY
[06:47:43] <CaptHindsight> the Casio projectors
[06:48:06] <CaptHindsight> sorry 460nm
[06:48:21] <SpeedEvil> XXCoder: thousands of hours are typical
[06:48:30] <XXCoder> interesting
[06:48:30] <SpeedEvil> (if not overdriven, and properly cooled)
[06:48:37] <CaptHindsight> often on ebay used for $200
[06:48:51] <XXCoder> frankly I have router and printer ill wait till I use em a buch heh
[06:48:58] <enleth> pink_vampire: you'd have to stick your face inside the work area to get hit with a focused beam
[06:49:17] <SpeedEvil> http://www.ebay.co.uk/itm/Coherent-9015-3-240-808-FAC-High-Power-Laser-Diode-808nm-240W-/112009032885?hash=item1a144234b5:g:dP8AAOSwa81XR8nb - for example - 240W laser diode.
[06:49:58] <SpeedEvil> This likely has ~50 emitters, you need to have 50 fibers going from this into a bundle
[06:51:11] <SpeedEvil> In general, all wavelengths of LASER behave differently
[06:51:19] <unfy^work> ebay / banggood / take-your-pick-of-chinese-stuff do have the 500-5000mw engraver things that are cheap diode based for not a terrible lot amount of money. might be worth experimenting with etc
[06:51:50] <unfy^work> if anything, you'll get the carraige assembly out of it to put your own heads on :/
[06:52:25] <SpeedEvil> your average cheap 3d printer is a great platform for the blue diode above.
[06:52:35] <unfy^work> orrrrrr that
[06:52:40] <XXCoder> SpeedEvil: indeed I have 2020 version of prussia i3
[06:52:44] <unfy^work> and with the excellent Z positioninig, focusing is easier.
[06:52:57] <XXCoder> I finally got replacement nema17 stepper so it should be working soon
[06:53:04] <SpeedEvil> I cheated.
[06:53:07] <SpeedEvil> https://www.amazon.co.uk/Wanhao-i3-V2-Duplicator-3D-Printer/dp/B017EU3PF0/ref=zg_bs_6283030031_1 I got that.
[06:53:23] <SpeedEvil> I was going to go for a more in-depth search of what to buy and how to get it cheapest and best.
[06:53:31] <SpeedEvil> But 'already assembled' and 'tomorrow'
[06:54:07] <unfy^work> i've been thinking about building a kossel (?) based printer... but... time is something i aint got ._.
[06:54:23] <SpeedEvil> yeah.
[06:54:42] <pink_vampire> how can i make a key slot in to a hardened gear?
[06:55:04] <unfy^work> annnnnd now that i've got this 4.5 month old maine coon kitten -- nothing setup in the apartment would be safe (and i'd rather not store a 3d printer in detached garage)
[06:55:09] <SpeedEvil> pink_vampire: hardened all the way?
[06:55:17] <SpeedEvil> pink_vampire: that is - in the centre?
[06:55:21] <SpeedEvil> or round the edges
[06:55:23] <XXCoder> unfy^work: completely enclosed printer
[06:55:50] <pink_vampire> i want to modify the top gears on my machine
[06:56:11] <SpeedEvil> pink_vampire: I would wonder about a tight-fitting plug, and simply drill on the line
[06:56:23] <SpeedEvil> (with carbide)
[06:56:30] <unfy^work> xxcoder: kitten would be offended that I'm attempting to keep him out of something, thus this would be the result: http://3.bp.blogspot.com/-1RWGZTEE1Sg/URgUrEBoasI/AAAAAAAAAaM/XDM7mDZNoKY/s1600/cats+destruction+myfriendshome.jpg
[06:56:36] <unfy^work> wow, nice ugly URL
[06:56:56] <XXCoder> cool your cat helped decoate the room ;)
[06:57:04] <pink_vampire> on the motor i have 20T gear and it spin a shaft with 37T
[06:57:34] <pink_vampire> and that give me now 1000 rpm with 50% of motor power
[06:58:03] <SpeedEvil> pink_vampire: do you have oxy/ac?
[06:58:12] <pink_vampire> so i want to change it to something that give me about 3000 rpm
[06:58:19] <SpeedEvil> If so, in principle, you could simply heat the point to remove the temper in that area
[06:58:41] <SpeedEvil> What is the bore?
[06:59:04] <pink_vampire> the motor is 14m, and the shaft is 15mm
[06:59:15] <SpeedEvil> how much power is this?
[06:59:28] <pink_vampire> stock gear have a bore of 10mm and no key way
[06:59:45] <pink_vampire> 1hp max (i'm working with 50%)
[07:00:03] <pink_vampire> so about 1/2 hp
[07:00:20] <SpeedEvil> Do you mean you want to drill out the gear to 15mm too?
[07:00:26] <SpeedEvil> And then put a keyway on it?
[07:00:37] <pink_vampire> yes
[07:01:06] <pink_vampire> but the the gear on the motor is made out of brass, and the gear on the shaft is plastic
[07:01:30] <unfy^work> i should prolly get going. another light cardio day while still recovering from a-fib earlier in the week. ciao & tnx guys o/
[07:01:40] <SpeedEvil> pink_vampire: where does 'hardened' come in?
[07:01:46] <SpeedEvil> unfy^work: good luck
[07:02:17] <pink_vampire> if i'm getting a new gear it's going to be hard
[07:03:01] <pink_vampire> so other way it maybe to make my own gear out of aluminum or cold rolled steel
[07:03:22] <SpeedEvil> A hardened gear to run against plastic?
[07:03:25] <SpeedEvil> Or brass?
[07:03:36] <pink_vampire> no no no
[07:08:01] <CaptHindsight> http://www.3ders.org/articles/20160901-winsun-china-unveils-fully-3d-printed-public-toilets-at-da-yang-mountain-suzhou.html
[07:09:09] <XXCoder> fancy.
[07:09:34] <XXCoder> even come with "trees"
[07:11:52] <_methods> finally a fitting use for 3d printers
[07:12:53] <CaptHindsight> to collect your bio-extrusions
[07:13:40] <XXCoder> yep we all 3d print hotdogs
[07:15:55] <SpeedEvil> http://turdtwister.com/
[07:24:47] <_methods> 3d print the turd twister
[07:30:46] <archivist> then it will need polishing!
[07:32:16] <XXCoder> turd is polishable
[07:32:33] <XXCoder> in least what i recall from one article lol
[07:32:50] <malcom2073> Mythbusters did that one
[07:32:51] <XXCoder> https://www.discovery.com/tv-shows/mythbusters/videos/polishing-a-turd-minimyth/
[07:32:55] <XXCoder> yeah
[07:32:55] <malcom2073> yeah
[07:33:15] <XXCoder> https://www.youtube.com/watch?v=yiJ9fy1qSFI for people who want youtube
[07:34:59] <malcom2073> It still gets me, that competitive turd polishing is a thing
[07:35:29] <malcom2073> If it exists, there are people that do it for fun.
[07:35:51] <SpeedEvil> malcom2073: elections
[07:36:02] <_methods> hahah
[07:36:15] <_methods> politics = competitive turd polishing
[07:36:34] <malcom2073> I'm not convinced there is any polishing involved
[07:36:54] <SpeedEvil> Oh there is, for most candidates
[07:37:01] <SpeedEvil> they have a team of people working on their image
[07:39:16] <_methods> polishing to a bright orange shine
[07:39:18] <_methods> lol
[08:00:22] * JT-Shop heads out for a morning ride
[08:04:09] <XXCoder> if you cant sleep because you lack nightmares... https://www.youtube.com/watch?v=tAqpGZw5TT0
[08:57:40] <miss0r> Is it just me or is grbl somewhat shitty?
[08:57:57] <jdh> #linuxcnc
[08:58:04] <malcom2073> miss0r: Not just you.
[08:58:09] <malcom2073> It's "good enough".
[08:58:31] <miss0r> i'm just running this x-carve in air cut, and I think the steppers are sounding funny/uncrontrolled
[08:58:42] <archivist> someone tested and compared id, it breaks the odd acceleration rule
[08:58:46] <malcom2073> grbl assumes that infinite acceleration is not only possible, but recommended.
[08:59:13] <archivist> in other news a bag of shite
[08:59:16] <miss0r> that makes sense. this is why it sounds funny
[08:59:27] <_methods> storm hitting you yet jdh
[08:59:49] <jdh> I'm in north florida at the moment. came through last night
[08:59:54] <malcom2073> miss0r: grbl works if your machine is flimsy, or really really slow. Otherwise it's not much use
[09:00:18] <miss0r> malcom2073: this is an x-carve - it qualifies for both
[09:01:04] <miss0r> I am going to see what the quality is of the project I am planning here. if it is poor, I will install the stepper controller I have laying around and run linuxcnc
[09:01:20] <malcom2073> Yeah
[09:01:25] <_methods> ah you ran down to meet it
[09:01:55] <_methods> heavier bands just starting to land here now
[09:09:13] <miss0r> is this another one of thoes crazy storms you guys are having?
[09:12:43] <_methods> hurricane/tropical storm now
[09:14:08] <miss0r> how bad is it, compared to cathrina/kathrina. I visited the south some time after and saw the damage
[09:19:20] <jdh> I drove through the outer bands coming down yesterday.
[09:20:05] <miss0r> what is it named?
[09:20:06] <_methods> it's not bad so far
[09:20:08] <_methods> hermine
[09:20:23] <_methods> but it won't be where i'm at
[09:20:27] <_methods> florida took the steam out of it
[09:20:52] <_methods> just going to be some rain here and some moderate winds
[09:22:33] <miss0r> we had a hurricane here in Denmark back in '99. It did some damage and the sealevels went up 22 feet or so. They are still talking about it all the time, and comparing what is happending in the US with it. which is silly, as we have/have never had anything compared to what you shrug off as windy weather :)
[09:23:41] <miss0r> and they keep saying "the water levels were probally even higher, but the meter broke" :)
[09:23:51] <_methods> well i don't really worry too much unless it's cat4 or cat5
[09:24:07] <_methods> cat3 and below is just a good excuse for a hurricane party
[09:24:53] <miss0r> Me neither. I live in a somewhat secluded area, every time the wind blows a little, some electrical cables fall down/gets ripped out of the ground by the roots of a tree falling over. So I have a backup generator.
[09:25:16] <miss0r> if a cat(insert any number here, even -5) hits, we have problems :)
[09:27:16] <_methods> we get so much lightning around here the grid is fairly reliable, most of it is underground and what isn't is well bonded in the southeast us
[09:27:35] <_methods> the rural areas can be a bit less reliable
[09:27:45] <CaptHindsight> what's the simplest way to get an analog voltage as feedback for motor position into Linuxcnc?
[09:28:07] <miss0r> analog/digital converter
[09:28:19] <CaptHindsight> I'm using a capacitive sensor for position
[09:28:31] <CaptHindsight> miss0r: duh
[09:28:34] <archivist> or maybe v-f converter
[09:28:45] <CaptHindsight> 1Khz bandwidth
[09:29:10] <archivist> actually use the C oscillator direct
[09:29:44] <archivist> like the old HP pen plotter did
[09:29:56] <CaptHindsight> is there a mesa board with a driver with ADC?
[09:36:03] <CaptHindsight> the 7i87 has 12b ADC's
[09:39:00] <CaptHindsight> 12bits across 120mm (120/4096 = 29um
[09:40:01] <Deejay> +)
[09:42:03] <CaptHindsight> maybe I'll have to make a 16bit ADC with a smart serial interface
[09:43:07] <CaptHindsight> pcw_home: do you have a higher res ADC than the 7i87?
[09:45:13] <pcw_home> No but i'm thinking of adding one based on the TI AD1262/3
[09:46:32] <pcw_home> sorry ads1262/3
[09:46:51] <CaptHindsight> 7i87 at 16b has a bandwidth of 200hz?
[09:57:04] <pcw_home> yes
[09:57:05] <pcw_home> what resolution, speed, and number of channels do you need?
[10:00:11] <Simonious> morning gang
[10:02:47] <CaptHindsight> pcw_home: just 2 channels, 14bits, 1Khz
[10:10:51] <CaptHindsight> controlling 2 http://www.camtech.com/index.php?option=com_docman&task=doc_download&gid=318 galvo motor with capacitive position sensor
[10:14:57] <pcw_home> 1 KHz feedback is probably not enough you probably need a DSP
[10:15:22] <CaptHindsight> not running them anywhere near full speed
[10:19:53] <CaptHindsight> sintering plastic vs light show
[10:21:50] <pcw_home> Might work for slow corrections, but note, you are dealing with a device 10 to 100 times higher mechanical
[10:21:52] <pcw_home> bandwidth than a normal CNC machine so needs a faster feedback loop to be stable with high gain feedback
[10:32:12] <enleth> pcw_home: does Mesa make a daughter card that could be used for data acquisition on 20-40 12bit or better ADC channels at 20kHz or better?
[10:32:29] <enleth> a combo of two daugter cards to get 40 channels would be OK
[10:34:37] <archivist> 1.6 MB a sec
[10:37:45] <enleth> derp, wait, 5kHz or better
[10:42:42] <pink_vampire> hi
[11:07:34] <pcw_home> 20 KHz is tough for a LinuxCNC servo thread
[11:08:42] * JT-Shop just got back from a 20 mile ride
[12:04:43] <wasutton3> is there a way to have my cnc automatically home after the completion of a job?
[12:05:41] <cradek> no, but it can go to a certain known location at the end of the program if you put that in the gcode
[12:06:13] <cradek> that's pretty normal (especially lift the tool all the way up at the end)
[12:06:53] <ktchk> add line at the end of program g53 g0z0x0y0 will home the spindle
[12:10:26] <wasutton3> ktchk, cradek gotcha. I knew i could add that to the gcode, just didn't know if it was a hidden option or no
[12:11:03] <MacGalempsy> finally, got the drives tuned pretty dang good
[12:11:24] <MacGalempsy> there is still a little spike of 0.00009" at the beginning
[12:11:35] <ktchk> that is the duty of the gcode generator not linuxcnc
[12:12:04] <Simonious> I may be wrong, but g53 z0x0y0 seems like a bad plan, i suggest g53 z0 followed by g53 x0y0 so there is less change of dragging the tool through the work
[12:12:19] <Simonious> *chance
[12:12:31] <enleth> pcw_home: it's not even for linuxcnc, just looking for a DAQ board for a non-CNC project
[12:12:41] <ktchk> right it will go in angle and cut the wall
[12:19:07] <Simonious> linuxcnc supports 9 work coordinate systems at this time?
[12:19:26] <cradek> yes
[12:20:55] <Simonious> This doesn't really affect me, but it seems for the programmer it would have been very little effort to extend this to 2 orders of magnitude larger?
[12:21:04] <FloppyDisk525> A little late JT-Shop, but nice ride... I did a little swimming this AM and smell a bit like a pool...
[12:23:29] <pink_vampire> if i need 1:1 gear ratio, there is any effect to the numbers of tooth?
[12:24:31] <pink_vampire> 50T to 50T or small 200T to 200T, give the save ratio, but is there any advantage?
[12:24:44] <roycroft> it will last longer with more teeth, generally
[12:24:55] <roycroft> oh, same diameter
[12:25:05] <FloppyDisk525> Don't go so small you're tighter than the belt bend radius.
[12:25:45] <FloppyDisk525> I suppose you could get all technical and look at the inertia of a disk for the pulley, but it'll probably be negligible.
[12:26:54] <MacGalempsy> pink_vampire: a better way to ask is 1:1 ok or is 1:1 ok?
[12:27:52] <MacGalempsy> i agree, its neligible
[12:30:57] <archivist> pink_vampire, all to do with tooth strength, so very fine teeth are less strong, but also can have less backlash, so it is a choice
[12:34:31] <pink_vampire> backless is not important
[12:34:59] <pink_vampire> I'm more concern about noise
[12:35:40] <archivist> for edm I dont think noise is a problem
[12:37:59] <pink_vampire> it's for my spindle
[12:38:18] <JT-Shop> FloppyDisk525: we had to work hard the whole way... head wind both directions go figure
[12:38:59] <archivist> pink_vampire, for spindle low count for strength, helical for quiet
[12:39:35] <pink_vampire> what about round?
[12:40:10] <archivist> gears are round
[12:40:25] <pink_vampire> http://i.imgur.com/paEAjWC.png
[12:40:35] <pink_vampire> something like that
[12:40:44] <archivist> rubbish shape
[12:40:47] <pink_vampire> very easy to machine
[12:40:53] <archivist> very noisy
[12:41:02] <pink_vampire> why?
[12:41:11] <archivist> violate the rules of gearing
[12:41:33] <pink_vampire> what do you mean??
[12:41:33] <archivist> absolute junk
[12:42:02] <pink_vampire> but why
[12:42:06] <MacGalempsy> i am using GT2 pulleys and drive belts on my machine
[12:42:25] <archivist> learn about how gears transfer load from tooth to tooth
[12:42:30] <MacGalempsy> maybe if you start to square off the teeth
[12:42:40] <archivist> involute
[12:42:45] <pink_vampire> i don't want to use pulley
[12:43:17] <pink_vampire> is there a "name" for my gears?
[12:43:28] <archivist> buy them in do not mess about
[12:43:29] <FloppyDisk525> For a spindle, pulley and belt would be fine... GT2 is a nice profile, you could also go MXL or XL...
[12:44:22] <Simonious> pink_vampire: you may find a nice gear generating tool here: http://woodgears.ca/
[12:44:53] <pink_vampire> i want to just get higher ratio between the gears now is 1:1.85 and i want to get it to 3:1
[12:45:15] <archivist> wood gears are no good for power transmission
[12:46:09] <pink_vampire> i want to make them out of metal aluminum is very easy to machine
[12:46:20] <pink_vampire> now it's brass and plastic
[12:46:38] <archivist> aluminium is a poor gear material
[12:47:05] <pink_vampire> i know
[12:47:15] <pink_vampire> it is very soft
[12:47:39] <pink_vampire> i have brass sheet but it's too thin
[12:47:52] <Simonious> http://woodgears.ca/gear_cutting/template.html
[12:47:54] <archivist> buy them
[12:47:57] <pink_vampire> and i have cold rolled steel bar
[12:48:09] <Tom_itx> use a round wood center with pegs driven in the edge
[12:48:21] <archivist> fsk wood gears
[12:48:49] <SpeedEvil> Nothing wrong with wood gears - for a very limited range of powers and speeds
[12:49:05] <archivist> wood is TOTALLY wrong for this application
[12:49:17] <SpeedEvil> For 1/2 horse - just no
[12:49:19] <pink_vampire> the smallest end mill that i have for the thickness is 1/8"
[12:49:38] <archivist> do not endmill gears
[12:50:29] <archivist> unless you know how to generate the involute and have a rotary table
[12:50:30] <Tom_itx> JT-Shop, i named my dog 'twenty miles', now i can say i walk 20 miles every day
[12:50:57] <pink_vampire> i don't have horizontal milling machine / 4th axis / rotory table etc..
[12:51:02] <JT-Shop> lol
[12:51:13] <archivist> then just buy standard gears
[12:51:45] <pink_vampire> archivist: but i can find something that fit between the centers
[12:51:49] <archivist> http://www.hpcgears.com/
[12:51:58] <pink_vampire> and also with the right hole
[12:52:17] <archivist> there are many gear makers out there with off the shelf gears
[12:52:35] <Tom_itx> check stock drive products
[12:52:38] <pink_vampire> i need 14mm for the motor + key, and 15mm for the other shaft
[12:52:46] <Tom_itx> sdp-si com iirc
[12:53:43] <archivist> ask them for the bores you want, small extra cost
[12:53:48] <pink_vampire> what is "mod"
[12:54:29] <archivist> gears are two basic standards MOD (metric) or DP (inch)
[12:55:12] <pink_vampire> i think my machine use metric
[12:55:28] <archivist> probably mod 1
[12:55:38] <MacGalempsy> https://www.flickr.com/photos/58181938@N03/29408808055/in/dateposted-public/
[12:56:20] <archivist> pink_vampire, tell me the OD and number of teeth of a current gear
[12:56:31] <MacGalempsy> got one of the brackets roughed out for the 3d printer. for my first multi setup part, I think it cam out pretty good. one side is about 2mm short, but the rest fall in spec
[12:57:08] <MacGalempsy> learning what was done wrong is part of the fun, as long as wrong wasnt catostrophic.
[12:57:48] <archivist> if catastrophic redo from start
[12:58:05] <pink_vampire> the small gear is 20T and it's 28mm OD. the larger gear is 37T and it's 49.27mm OD.
[12:59:01] <archivist> about 1.25 mod
[12:59:37] <pink_vampire> I can't measure the distance between the centers.
[12:59:43] <archivist> probably 1.3, just looking at a table not calculating
[12:59:44] <MacGalempsy> the finish quality isnt too good, so maybe the bit is dull
[13:00:29] <pink_vampire> I wish i know how it work
[13:02:06] <archivist> pink_vampire, on that HPC site is a pdf with all the maths to calculate gears
[13:02:16] <MacGalempsy> so doing that manual PID tune this morning I had to do PID and FF1 and FF2
[13:03:07] <MacGalempsy> roughing out the Oscillation period with HALScope made the ziegler-nichols method a snap.
[13:03:12] <MacGalempsy> at least for a ballpark
[13:03:26] <archivist> pink_vampire, http://www.hpcgears.com/n/left_menu/technical/technical.php see the gears section
[13:04:42] <archivist> sdp has something similar iirc
[13:04:57] <pink_vampire> what is iirc?
[13:05:13] <archivist> if i remember correctly
[13:05:26] <archivist> standard abr
[13:06:51] <pink_vampire> good to know
[13:06:56] <pink_vampire> :)
[13:07:41] <pink_vampire> https://lh5.googleusercontent.com/-1Ga7DuzTcv4/VRddqLxVnyI/AAAAAAAAy6U/oGi8MkQYQ9g/w1278-h719-no/20150328_190418.jpg
[13:07:49] <pink_vampire> this is the large gear
[13:09:14] * archivist never sees any google /flickr image
[13:09:40] <archivist> actually can see that one
[13:09:52] <archivist> replace with helical
[13:12:45] <MacGalempsy> helical endmill?
[13:12:58] <archivist> no helical gear
[13:16:24] <pink_vampire> the distance between the centers is 36mm
[13:17:02] <pink_vampire> and my goal is 3 to 1 ratio
[13:17:26] <pink_vampire> do you think it will work?
[13:17:56] <archivist> if you add another pair
[13:18:38] <pink_vampire> i cant
[13:18:52] <pink_vampire> i need to replace the originals
[13:19:07] <archivist> you can, means adding a pillar with an idler
[13:20:39] <pink_vampire> i can't just replace the one on the motor with large one lets say 30T and on the shaft to place a 10T gear?
[13:20:42] <Frank_18> guys im going crazy, cant find a ballscrew coupler that goes 19mm to 10mm, maybe someone can show me a webpage where they sell some stuff
[13:20:52] <Frank_18> i've searched mcmaster already
[13:21:17] <archivist> pink_vampire, your bearings will not like the extra speed either
[13:21:30] <pink_vampire> 19mm is 3/4"
[13:21:38] <pink_vampire> 3/4" is 19.05mm
[13:21:43] <Frank_18> yep
[13:21:59] <pink_vampire> looking for 10mm to 3/4"
[13:22:32] <Frank_18> hard
[13:22:47] <pink_vampire> the bearings rated to 4000-5000 rpm
[13:23:01] <pink_vampire> now i'm on 1000 rpm
[13:23:24] <pink_vampire> the speed of the motor before gearing is 1850 rpm,
[13:23:58] <pink_vampire> so 1850 times 3 put me on 5550 rpm
[13:24:08] <Frank_18> maybe i should just use pulleys
[13:24:44] <pink_vampire> frank just use the machine to make the hole larger
[13:24:46] * archivist expects a burnt motor and hot bearings
[13:24:57] <pink_vampire> archivist: why?
[13:25:13] <pink_vampire> it's 1000 rpm on 50% of the power
[13:25:25] <archivist> I have seen a chinese mill get hot at normal speeds
[13:25:44] <archivist> losses rise when you multiply speed
[13:25:52] <Frank_18> there is no machine yet, need the coupler to have the machine hehe, thanks thou,
[13:26:30] <pink_vampire> i mean use it manual with a boring head and dial indicator
[13:28:02] <pink_vampire> as long that i'm keep it at the 4000-4500 rpm i'm fine even without upgrade the original bearings
[13:28:37] <pink_vampire> archivist:
[13:29:01] <pink_vampire> i'm using only small endmils 1/8"-1/4"
[13:29:31] <pink_vampire> so the load on the motor is very low
[13:30:18] <renesis> guys, new noisia radio (is music for cnc machines, they like it it will increase your tool life and reduce all error to zero)
[13:30:22] <renesis> https://soundcloud.com/noisiaradio/noisia-radio-s02e36
[13:30:39] <archivist> the load of spinning a spindle is not to be sniffed at
[13:31:37] <pink_vampire> archivist: i'm not sure what do you mean
[13:32:12] <archivist> the loss of power in the spindle rises a lot with rpm
[13:32:33] <pink_vampire> i know
[13:32:40] <pink_vampire> but how much?
[13:32:59] <pink_vampire> is there a way to measure it?
[13:33:23] <archivist> depends on grease, how good the bearings are and adjustment
[13:34:18] <pink_vampire> i need to provide about 50W of rotation energy
[13:34:39] <archivist> for cheese cutting yes
[13:34:40] <pink_vampire> and the motor take 1/2 hp
[13:34:57] <pink_vampire> for 1/8" end mill 4F
[13:35:28] <archivist> steel milling at 5k rpm, maybe a "bit" more
[13:36:10] <pink_vampire> in general I'm taking 0.5mm DOC, and 150mm/min feed on aluminum
[13:36:23] <pink_vampire> and i'm happy with the cutting
[13:37:06] <archivist> download that pdf and choose any pair that fits
[13:37:30] <pink_vampire> how i know if it's fit?
[13:37:44] <archivist> dont come crying if wears out in a few minutes
[13:38:17] <pink_vampire> i only know the distance between the centers (36mm)
[13:38:24] <archivist> because PCD/2 of gear 1 +pcd/2 of gear 2 = centre distance
[13:39:23] <pink_vampire> and what mod i need?
[13:40:20] <archivist> I already stated, this will be noisy unless you use helical gears
[13:41:10] <pink_vampire> it's an experiment
[13:42:27] <pink_vampire> there is PARALLEL Helical and CROSSED Helical gears
[13:42:36] <pink_vampire> what is better?
[13:43:25] <archivist> spur or helical, crossed helical is shafts at an angle
[13:43:42] <archivist> helical
[13:44:01] <pink_vampire> i'm trying to see in google images
[13:44:48] <pink_vampire> http://blog.misumiusa.com/wp-content/uploads/2014/10/Helical-Gear.png
[13:44:58] <pink_vampire> this is the crossed?
[13:45:09] <archivist> http://hpcgears.com/n/products/13.helical_gears/helical_gears.php
[13:45:29] <archivist> yes that is crossed
[13:45:57] <pink_vampire> the larger the mod = ?
[13:46:21] <pink_vampire> larger tooth?
[13:46:37] <archivist> larger mod stronger tooth, noisier
[13:47:01] <pink_vampire> mmm
[13:47:26] <pink_vampire> so if i have 36mm
[13:48:17] <pink_vampire> i need to find something like 36 pdc on each gear to get 1:1 ratio?
[13:48:28] <archivist> PCD
[13:48:51] <archivist> yes
[13:50:22] <pink_vampire> so together the distance between centers is = to the half of the combine pcd of both gears?
[13:50:47] * archivist points at the technical pdf again
[13:51:35] <pink_vampire> I'm trying to see what you mean
[13:52:20] <archivist> all the calcs are in the technical pdf, make a spreadsheet experiment
[13:53:17] <archivist> like http://www.engineersedge.com/calculators/helical-gear-calculator.htm
[13:54:00] <archivist> that happens to be in DP
[13:55:17] <pink_vampire> i need to put 0.8 on the dp
[13:55:21] <pink_vampire> 1/1.25?
[13:55:47] <archivist> about 19 DP for your current pair
[13:56:30] <Crom> what the heck.. freecad is being removed by apt-get
[13:56:35] <Crom> grrrr
[13:56:48] <Simonious> classy
[13:57:25] <pink_vampire> with 0.8, i got 36.4665 inch
[13:58:00] <pink_vampire> i know it wrong, but is very close to the real value
[13:58:26] <archivist> 19DP nothing like real value at all
[13:59:05] <pink_vampire> i need to fined metric calculator like that
[14:00:00] <archivist> make it in a spreadsheet
[14:00:38] <pink_vampire> mmmm
[14:01:41] <pink_vampire> https://www.youtube.com/watch?v=Zi8_CLY3fAo
[14:02:01] <archivist> I have done a couple of online calculators but not for spur or normal helical yet
[14:02:41] <pink_vampire> you have an opportunity now..
[14:02:59] <archivist> too lazy
[14:03:20] * Simonious doubts archivist is lazy
[14:03:32] <Simonious> otherwise occupied perhaps?
[14:03:43] <archivist> crossed helical http://www.archivist.info/gear/designcrossedhelical.php
[14:04:20] <pink_vampire> but I'm sooo cute.. and I have beautiful smile, how you can say no to that...
[14:04:35] <archivist> easy
[14:05:23] <Simonious> pics or it's a lie (do people still say that?)
[14:05:53] <MacGalempsy> live stream huh? where is the orgy dome?
[14:05:54] <archivist> I actually have a spreadsheet so that is why there is no online spur calculator
[14:06:21] <pink_vampire> :(
[14:06:48] <pink_vampire> i need a 3d printer
[14:06:57] <pink_vampire> no spindle
[14:07:05] <Simonious> I've got two here you can use.. they could use some tuning though
[14:07:33] <pink_vampire> where are lo located?
[14:07:39] <Simonious> Central Minnesota
[14:07:43] <pink_vampire> you*
[14:07:50] <pink_vampire> i'm in ny
[14:08:17] <Simonious> Been there once.. wandered around the Falls and the orchards.
[14:08:25] <archivist> I am in the dining room
[14:09:05] <pink_vampire> 25hours driving
[14:09:14] <archivist> near the arrow http://www.collection.archivist.info/shelfview.php?src=artitle&locid=197
[14:10:11] <pink_vampire> you don't have ocd
[14:11:33] <archivist> my kitchen says no, barcided library.....
[14:11:39] <archivist> barcoded
[14:12:27] <pink_vampire> will you marry me???
[14:12:44] <archivist> no!
[14:13:24] <pink_vampire> how can you do this to me???
[14:14:00] <archivist> I have managed to stay old free and single
[14:15:49] <Simonious> so if I use my now functioning HOME to home the machine and then position the toolhead at the work and do an xyz touchoff and hit run, will this work well? http://pastebin.com/P4MgBFhn
[14:16:51] <archivist> run it cutting air
[14:17:10] <witnit> maybe try building a simulator halfile you can test run all your work from office before going into shop floor
[14:17:54] <Simonious> witnit: I don't have the experience to know what that means.. I can simulate the run in fusion360 where the code was generated.
[14:18:34] <Simonious> archivist: is it normal to want to hand edit a few details on most generated gcode? maybe I need to do some editing of some configuration to modify how it is generated..
[14:19:10] <archivist> I dont use those cam programs anyway
[14:19:33] <witnit> I suspect you REALLY need to keep your hand hovering over the big red button
[14:19:38] <pink_vampire> i loooove cam
[14:19:50] <JT-Shop> new way covers are in but I don't feel like installing them...
[14:20:00] <Simonious> witnit: yeah, I dial the speed WAY down for a new run, do it in air and keep the button under hand
[14:20:10] <JT-Shop> my duct tape covers are prettier lol
[14:20:10] <archivist> cam does not deal with rotaries that well
[14:20:39] <Simonious> archivist: hand writing your code?
[14:21:03] <archivist> yes
[14:21:08] * Simonious nods
[14:21:19] <Simonious> I've done that for simple stuff, but I normally generate and then edit a little
[14:21:22] <archivist> using subroutines where I can
[14:21:38] <Simonious> makes good sense to me
[14:23:29] <archivist> end up short ish http://www.archivist.info/cnc/helical_worm2.ngc
[14:23:40] <pink_vampire> archivist: did you tried hand writing gcode for organic shapes?
[14:23:47] <archivist> and almost readable
[14:24:05] <archivist> I do regular shapes
[14:24:52] <Simonious> archivist: http://linuxcnc.org/docs/html/gcode/g-code.html#gcode:g64 is this helpful?
[14:25:59] <archivist> when you need it
[15:04:11] <witnit> Anyone really good with trivial kinematics or unusual toolpath generation?
[15:08:49] <pink_vampire> witnit: what do you mean?
[15:08:56] <witnit> Im pushing a spindle and shaft with one servo actuator on the "Z" plane, another actuator must move with it at the same rate since it is connected to the cutting tool. If either one speed up or slows down the cutter will move in and out on the "X" plane. Obviously normal X/Z lathe motion will not work for this.
[15:09:44] <witnit> x[actuator]===-----------|head ]^
[15:09:44] <witnit> z[actuator]===-----------|_____/
[15:10:12] <witnit> the cutting tool rides on a 27degree angle within the head.
[15:10:39] <witnit> so if both actuators move together no cutter movement, if one stops or they change speed the profiling ensues
[15:11:12] <andypugh> Do you want the G-code to be in X and Z?
[15:11:20] <witnit> yes like, lathe
[15:11:45] <andypugh> If so, then it’s an obviius application for custon kins. And JA-kins at that.
[15:11:46] <witnit> as this head is rotating around a center point and acting like a profiling roatry recess
[15:12:30] <witnit> this is where I need to understand how exactly I can translate normal lathe kins to this very unusual hardware
[15:12:38] <pink_vampire> witnit: do you have microphone?
[15:12:46] <witnit> yeah
[15:13:06] <pink_vampire> https://discord.gg/ANhbeZQ
[15:13:14] <pink_vampire> join here for sec
[15:14:40] <pink_vampire> I'm on the voice channel on the left
[15:16:39] <andypugh> I initally read “join here for sec” entirely incorrectly
[15:16:46] <witnit> hahahahahha
[15:17:02] <Deejay> lol
[15:17:27] <pink_vampire> andypugh: what do you mean????
[15:17:50] <witnit> ( ͡° ͜ʖ ͡°)
[15:18:04] <pink_vampire> ?
[15:18:30] <pink_vampire> any success?
[15:20:13] <witnit> I am not doing so well with this app hahah I will have to enable my audio through it in some way I thought it was right but to no avail
[15:20:43] <pink_vampire> do you have skype?
[15:23:01] <andypugh> witnit: Have you read: http://linuxcnc.org/docs/2.7/html/motion/kinematics.html
[15:23:05] <witnit> andypugh: https://ufile.io/ad355
[15:23:33] <witnit> yeah its a bit over my head until I start changing things and seeing how they work
[15:24:01] <Deejay> haha, ufile.io is blocked
[15:24:12] <witnit> sorry is it a shitty website?
[15:24:17] <andypugh> You basically just need to encode, in maths, how movements of the actuators lead to movements in space, and the reverse.
[15:24:17] <witnit> I dunno where to upload things
[15:24:44] <Deejay> firefox blocks this site. dunno know more
[15:24:52] <witnit> yeahhh I was hoping a I could compare the math in a similar design to a standard cartesian and go from there
[15:25:01] <witnit> where is a cool place to upload files jeesh
[15:25:03] <witnit> hahaha
[15:26:03] <witnit> http://s000.tinyupload.com/index.php?file_id=78678935199924033160
[15:26:06] <witnit> maybe that
[15:34:34] <witnit> I know the tools are there in a math formula and with proper coding I see how it works but i cant in my mind translate the relationships between joints, axis, and so forth.
[15:36:02] <witnit> Its like, IF the cutter needs to stay put then actuator must follow Z axis if not then they must move out of sync at given rates and im really hard to grasp the programming end of what I think I want in the physical
[15:36:05] <andypugh> What is the type of the file?
[15:36:12] <witnit> mp4?
[15:37:27] <andypugh> Favourites here are imagebin.ca for images, pastebin.ca for pasting simple text, and codepad.org for program code (as it highlights, and can even execute)
[15:40:32] <andypugh> MP4? maybe Youtube?
[16:18:18] <andypugh> Quite a colection of top-class tools: http://www.ebay.co.uk/itm/Various-machines-untested-/282157105171?hash=item41b1dfc013:g:md0AAOSwRGlXqFQ2
[16:21:08] <JT-Shop> I hate to see vintage machines sitting outside rusting...
[16:22:49] <andypugh> They don’t look too bad. Yet.
[16:23:29] <andypugh> My Holbrook looked terrible in photos, but actually scrubbed-up pretty well.
[16:25:04] * JT-Shop starts the holiday weekend an hour early
[16:25:59] <JT-Shop> my way covers came in today... need to install them
[16:26:57] <JT-Shop> I wonder if I should go to the trouble of writing the arc generator for the lathe over and use radius
[16:27:39] <Deejay> gn8
[17:20:19] <JT-Shop> I just got a package I ordered in June of 2016... usps at it's finest
[17:20:31] <yasnak> lol
[17:24:03] <JT-Shop> now I have to send it back as they have already replaced it...
[17:29:18] <pcw_mesa> We were in desperate need of 5I25/6I25 brackets and expected a USPS package from Taiwain
[17:29:20] <pcw_mesa> The USPS tried a Saturday delivery(so naturally no one was here) , and never tried again
[17:29:21] <pcw_mesa> Jess walked to the Post Office on a hunch and found that the package was there on a truck
[17:29:23] <pcw_mesa> waiting to be shipped back to Taiwan, so a lucky save
[17:29:55] <pcw_mesa> no notice, no re-try, nothing...
[17:30:04] <JT-Shop> wow, and I can believe it
[17:30:27] <JT-Shop> I sent a package to Canada and 4 days later it was "delivered" to me...
[17:33:35] * JT-Shop goes to check the deer feeder
[17:37:44] <pcw_mesa> JT-Shop: sorry I forgot to include the DPLL in theta last config i built, here a fixed one:
[17:37:46] <pcw_mesa> http://freeby.mesanet.com/7i92_7i76_7i85sd.bit
[17:46:30] <JT-Shop> thanks
[18:01:40] <Crom> heh Guberment at it's finest... Ive spent this afternoon following up on my VA claims... Joy Joy, NOT!
[18:02:33] <Crom> pcw_mesa, : you're right north of Hilltop mall right?
[18:10:03] <Crom> YEA! 1-2-3 blocks arrived!
[18:10:29] <Crom> ugh now I have to cut my 0.827" piece of AL
[18:20:04] <MacGalempsy> good evening.
[18:20:27] <MacGalempsy> what a PITA. HDDs went down...
[18:24:20] <pcw_mesa> Crom: yes a least for 10 months or so, a school bought the whole building complex here so we have to move by July
[18:26:13] <Crom> sheeshz.. That was actually a nice area of Richmond.. Giant Rd was pretty nice, don't know if they have class b buildings there
[18:27:20] <pcw_mesa> We're looking a a place in Pinole. You can walk to the bay from there so thats nice
[18:27:58] <Crom> My dad taught at the high school for a year there.. emergency shop teacher
[18:28:42] <Crom> Off San Pablo ave.. near the Nations?
[18:29:19] <pcw_mesa> the place we are looking at is close to Embers and Big O tires
[18:33:38] <Crom> niceoh yeah... just down the street from nations..
[18:34:06] <Crom> not that bad of area...
[18:35:15] <Crom> it's probably changed a bit in the last 15 years...
[18:35:53] <MacGalempsy> Drove thru Richmond at 0600 New Years Morning, was the best Bay Area traffic ever!
[18:37:12] <Crom> ugh... can't home the machine... bolt in the way
[18:37:25] <Crom> gotta change homing to other end.. ugh
[19:14:54] <Crom> wow this 3040 is slow in 6061
[19:15:47] <Crom> man... In-N-Out does not have the best burgers... Red Onion either pinole or el sobrante, #2 is nations
[19:16:47] <Crom> actually best ever is Joe's in San ANotnio, though she's probably dead now
[19:17:51] <Crom> I've been there when the health inspector's there.. His boss's boss is sitting at the counter having a burger... She passed..
[19:18:17] <Crom> you don't mess with prefection
[19:19:38] <Crom> hmm well... she might still be making burgers... she'd only be 90ish now
[19:22:42] <Crom> I'm bumbed... she died 3 years ago... A Neice took it over http://www.mysanantonio.com/food/restaurants/article/A-conversation-with-Susan-Prochnow-Joe-s-5336076.php
[19:23:44] <enleth> http://i.imgur.com/Fjv04N7.jpg possibly the ugliest power supply I've ever made but it works
[19:23:59] <enleth> who said hot glue couldn't be used to hold together a filter capacitor bank
[19:24:29] <enleth> it's enough as a temporary stopgap to power the ORAC's motors
[19:25:23] <Crom> If you are ever in San Antonio, you have to get a burger at Joe's! make believe you're a republican if you have too
[19:26:06] <tiwake> Crom: I just moved to lubbock, from oregon
[19:26:18] <Crom> looks like a transformer from a Yoocnc control

[20:08:19] <XXCoder> holy crap im home
[20:15:34] <Frank_18> am i crazy or i read somewhere that cable ties suck for tying cables lol
[20:16:49] <XXCoder> dunno?
[20:23:03] <malcom2073> They're really good at tying cables
[20:23:09] <malcom2073> They're really bad at a lot of other things
[20:25:18] <XXCoder> btw I read this when researching, it was hella funny. "Do not touch the silica while hot. When it is hot it can also become sticky to skin; so hot and sticky you'll wonder why it hasn't been weaponized."
[20:25:35] * Simonious snorts
[20:26:37] <Crom_> My wife has cracked it!! Teletubies is a kids 'The Prisoner'
[20:26:58] <XXCoder> nah theyre trapped aliens
[20:27:17] <XXCoder> notice how there is camera and even artifical sun that ensures they are constantly watched
[20:27:48] <XXCoder> nothing there is real because they dont want alien germs to get out
[20:28:54] <Crom_> prisoner also had cameras
[20:29:37] <Crom_> everything is planed
[20:29:44] <XXCoder> lol
[20:32:16] <Crom_> shades of truman
[20:32:33] <roycroft> i am not a number! i am a free man!
[20:33:55] <Crom_> best crossover.. Teletubie Borg
[20:34:32] <XXCoder> teletubbies + Alien facehugger = Barnie
[20:35:17] <XXCoder> err barney
[20:35:44] <Frank_18> i've literally jsut finished watching the truman show

[20:37:13] <XXCoder> ouch if borg ever adopted to magic lol
[20:37:15] <Crom_> My Little Pony Borg
[20:37:45] <XXCoder> they can then use magic to summon demons and borg-ize em
[20:38:02] <XXCoder> Federation would be so screwed
[20:38:21] <Crom_> gonna have to hop on my other computer and find that pic... Guy off the action man group did it years ago
[20:54:29] <XXCoder> https://youtu.be/GHiTDsFTFQQ
[20:54:36] <XXCoder> awesome I wanna one for fun lol
[20:54:44] <XXCoder> though its hard to use and store after few uses :P
[21:00:15] <Crom> another picture I want to find was connected to a very non-politically correct story.. It's a C-130 made up as a Short Bus, and the story is about the special troopers that use it.. Sgt Kenny, explained something about we can't got into the field for more than so many hours, then the troops need a nap, milk, and cookies
[21:00:40] <Crom> s/got/go/
[21:01:46] <Crom> AC-SB130 short bus C-130 with bb guns and air soft guns pointing out the side
[21:17:41] <enleth> Crom: my transformer? It was there originally, in the ORAC lathe. Single secondary, 54V across, several center taps I'm not even using
[21:18:48] <enleth> Crom: 70V rectified, which is perfect for the original motors (up to 90V, 75V recommended) and my new stepper drives (up to 80V), and much better than the original 35V used to drive those motors
[21:19:04] <enleth> (rectified and filtered, that is)
[21:50:24] <Crom_> looks like the one in my yoocnc
[21:50:47] <Crom_> nice
[21:51:14] <Crom_> mine is labeled, 18v and 36v
[22:17:58] <enleth> Crom: I'm pretty sure most toroidal traansformers of about any given size look more or less alike
[22:18:25] <XXCoder> they made it
[22:18:31] <XXCoder> 1,000 core cpu
[22:18:33] <XXCoder> insane.
[22:21:08] <MacGalempsy> this hdd recovery process sucks....
[22:37:14] <Tom_itx> been there
[22:37:26] <Tom_itx> fortunately i back things up
[22:39:27] <MacGalempsy> most of the good stuff was on a second drive. recovering the main disk now. it will be interesting to see how things work out. not too worried, but gets me thinking about a big jump drive
[22:41:08] <MacGalempsy> just glad there was a set of backup ssds ready to come online
[22:45:47] * enleth is waiting for a new workstation drive to replace one that died earlier this week
[22:46:16] <enleth> luckily nothing valuable wan on it, just the OS
[22:46:58] <MacGalempsy> just a few things in the my documents, but not much. hoping the other drive is still good.
[22:47:32] <MacGalempsy> there are 2 hours of recovery left, so im going to bed!
