[00:51:01] <MacGalempsy> yo
[01:12:27] <archivist> yasnak, barcodes, wifi barcode scanner, and a bit of php and mysql, that becomes a multiuser location database with maps if needed
[01:12:40] <yasnak> \^^
[01:13:03] <archivist> yasnak, similar to the way my books and manuals are done :)
[01:13:26] <yasnak> so uh
[01:13:28] <archivist> http://www.collection.archivist.info/shelfview.php?src=artitle&locid=197
[01:13:31] <yasnak> :P
[01:13:58] <archivist> http://www.collection.archivist.info/shelfview.php?src=artitle&locid=595
[01:14:38] <MacGalempsy> too much time...
[01:15:20] <archivist> I just bought a reel of ready made unique number labels
[01:15:47] <yasnak> yeah looking into this all now
[01:15:55] <LeelooMinai> Considering the nickname it all makes sense
[01:15:55] <yasnak> bought bartender labeling software as well as zebra\
[01:15:56] <archivist> each location gets a label too
[01:16:13] <yasnak> got three thermal label printers but ill get a dedicated one for the labeling
[01:16:25] <yasnak> and then a wireless barcode scanner for warehouse and tool room
[01:16:28] <archivist> I didnt like the price of zebra printers
[01:16:50] <yasnak> cuz front office sucks at keeping track of lot numbers, it will help everyone lol
[01:16:54] <archivist> I got a wireless scanner for £20 second hand
[01:17:21] <archivist> also have a Symbol scanner next to pc
[01:19:51] <archivist> there is some "fun" for items within items(containers) in locations
[01:30:36] <archivist> yasnak, a stock check script updates where things are/marks them as lost
[02:37:25] <Deejay> moin
[02:38:47] <yasnak> mornin
[02:39:10] <yasnak> archivist, i'll get back to ya on that. need to head home for a solid 3 hours nap before work :P
[02:39:39] <archivist> okdoky
[05:50:22] <jthornton> morning
[05:50:32] <XXCoder> yo
[06:33:58] <abetusk> I've just used pstoedit to convert a ps file to an emc2 gcode file but I see all these (what I assume are) emc2 position variables (i.e. "G01 X[#1003*4.26935] Y[#1004*594.665]"). Is there a tool I can use to evaluate all those variables to make a flat gcode file?
[06:34:19] <abetusk> Please excuse my ignorance, I don't use linuxcnc...
[06:37:18] <jdh> a calculator
[06:38:44] <abetusk> jdh, so I have to create a tool myself to do this?
[06:42:24] <jthornton> http://linuxcnc.org/docs/2.7/html/gcode/overview.html#gcode:expressions
[06:42:27] <jthornton> yep
[08:22:11] <unfy> morning
[09:18:43] <MacGalempsy> morning
[09:23:27] * JT-Shop should be doing something I'm sure of it
[09:26:50] <MacGalempsy> considering going to metric interface on the cnc...
[09:29:06] <MacGalempsy> well, make another setup
[09:41:35] <jdh> .001 is such a convenient number
[09:42:33] <jdh> reasonable accuracy for most things and easy to think of
[11:11:11] <yasnak> jdh, so you tolerance everything at 0.001"? i hope you're in grinding
[11:11:48] <gregcnc> microns are more fun
[11:12:00] <jdh> reasonable for most
[11:12:08] <archivist> try a tolerance of a 1mm dia press fit :)
[11:12:47] <yasnak> i mean, idk. production machining and 0.001" mix best with $
[11:13:04] <archivist> not that any documentation ever specs tiny press fits
[11:14:41] <CaptHindsight> http://www.industrial-lasers.com/content/dam/ils/online-articles/2012/06/1206ILSfa32f14.gif
[11:17:35] <MacGalempsy> well, scored a few things so far
[11:17:43] <MacGalempsy> 6x6 magnetic sine plate
[11:18:04] <MacGalempsy> a precision horizontal drill press
[11:18:13] <gregcnc> http://www.businessinsider.com/the-worlds-first-edible-drone-2016-9
[11:18:16] <MacGalempsy> trying to get the pulse edm right now at 300
[11:20:06] <CaptHindsight> few nm precision machining with ion beam http://www.jcnabity.com/fibmill1.htm
[11:33:59] <MacGalempsy> 45 seconds left...
[11:34:56] <MacGalempsy> got it
[11:36:23] <MacGalempsy> so that is 3 pieces for $1k
[11:36:59] <SpeedEvil> MacGalempsy: yay!
[11:37:08] <MacGalempsy> yeah. pretty stoked.
[11:37:12] <SpeedEvil> MacGalempsy: new total? $100k?
[11:37:24] <MacGalempsy> well, maybe not that much
[11:37:30] <MacGalempsy> but maybe $10k
[11:37:41] <SpeedEvil> :)
[11:37:58] <gregcnc> what are you gearing up for?
[11:38:20] <archivist> a full garage
[11:38:38] <SpeedEvil> gregcnc: what - there has to be a purpose to buying tools?
[11:38:39] <MacGalempsy> http://www.thebranfordgroup.com/ Rando Auction Lots 70 99 103
[11:38:43] <SpeedEvil> I've been doing this all wrong!
[11:39:03] <MacGalempsy> gregcnc: I am trying to get the stuff together to have a small plastic injection shop
[11:39:14] <roycroft> the purpose of buying tools is to justify building new extensions to the shop
[11:39:15] <gregcnc> cool
[11:39:30] <MacGalempsy> with the EDM, I can cut the electrodes on the CNC
[11:39:59] <SpeedEvil> And use EDM to machine tooling for the CNC
[11:40:04] <MacGalempsy> the other aspect is capital investment, i figure if things dont work out, I can sell some of this stuff for a lot more than I have into it
[11:40:49] <MacGalempsy> the guy at the shop said the little drill press can drill a 0.003 hole
[11:41:00] <MacGalempsy> I thought that was pretty cool
[11:42:21] <MacGalempsy> what good is an edm sonic vibrator?
[11:42:42] <SpeedEvil> I assume to kill bubbles
[11:43:01] <MacGalempsy> ah. ok. there is one here that no one is bidding on for $10
[11:44:22] <archivist> grabbing the cheap stuff because nobody knows what it is :)
[11:45:03] <MacGalempsy> yeah. I think that is good. maybe ebay some of the old stuff
[11:45:35] <archivist> sometimes it is just no competing buyers, got a cheap renishaw probe that way
[11:46:04] <MacGalempsy> awesome. each place had giant CMM, but I think neither got sold
[11:46:08] <MacGalempsy> so huge
[11:49:00] <archivist> go make an offer before the crap man does
[11:49:05] <archivist> scrap
[11:49:20] <MacGalempsy> i dont even have anywhere to put them, let alone move them
[11:50:16] <archivist> my CMM had no competition on ebay, I did have access to a van at the time
[11:50:35] <MacGalempsy> these ones have like 6' tables
[11:50:39] <MacGalempsy> heavy!
[11:51:03] <archivist> mine is a lot smaller but not too light
[11:51:27] <MacGalempsy> now I need to start rearranging the garage...
[11:51:38] <archivist> I calculated around 250 kg for the granite
[11:53:08] <MacGalempsy> granite is usually 2.65g/cm^3 depending on the accessory minerals. funny how a black plutonic rock that is hard is named granite...
[11:54:17] <MacGalempsy> http://www.sandatlas.org/qapf-diagram/
[11:54:48] <MacGalempsy> probably more like a gabbro
[11:56:04] <CaptHindsight> MacGalempsy: when will the New Madrid break loose and swallow up the Midwest?
[11:56:27] <MacGalempsy> well it did release in the late 1800s and the mississippi flowed backwards
[11:56:31] <MacGalempsy> so it could happen again
[11:56:37] <MacGalempsy> it is a failed rift valley
[11:57:09] <CaptHindsight> what would it be like if it didn't fail?
[11:57:31] <MacGalempsy> it would be similar to the persian gulf
[11:57:51] <MacGalempsy> the mississippi river would be a separation between continents
[11:58:20] <MacGalempsy> luckily, southern arkansas and louisiana were ripped away to SA and northern africa
[11:58:43] <CaptHindsight> so in the future the Mississippi river banks will become beach fronts?
[11:58:54] <MacGalempsy> no it already failed
[11:58:58] <CaptHindsight> ah
[11:59:00] <MacGalempsy> so they major stresses are gone
[11:59:46] <CaptHindsight> is the Gulf of Mexico likely a meteor crater?
[12:00:29] <MacGalempsy> CaptHindsight: close, you have heard of the Chixlabub crater?
[12:00:43] <MacGalempsy> pretty recent work drilling the outer rim
[12:00:44] <CaptHindsight> just now
[12:01:01] <MacGalempsy> that is supposed to be the big one that wiped out the dinos
[12:01:12] <MacGalempsy> K-T boundary
[12:01:29] <gregcnc> I might crater my PC if I can't figure out how to stop the W10 "upgrade"
[12:01:56] <archivist> easy wipe it install linux
[12:01:57] <MacGalempsy> you will need to remove the Windows Update that has the procedure
[12:01:59] <CaptHindsight> kill the update service
[12:03:53] <gregcnc> i might just stop updates completely. i removed kb3035583 but it still wants to install
[12:04:11] <MacGalempsy> you removed, but did you delete the cached file?
[12:06:50] <MacGalempsy> just got the EDM sonic vibrator for $22
[12:07:07] <MacGalempsy> I might attach that to the bed like at the hotel!
[12:16:19] <MacGalempsy> so now the garage cleaning... breaktime first
[12:50:07] <CaptHindsight> http://www.ebay.com/itm/UltraHigh-Accuracy-CMM-/231943758341 $110K
[12:50:55] <abetusk> is there a grammar file anywhere for ngc?
[12:52:45] <gregcnc> http://linuxcnc.org/docs/2.7/html/ under G code programming
[12:54:18] <oussama> Hello , how can i solve this problem '' missing handler 'gremlin_readraw' "
[13:03:42] <oussama> can you help me please ?
[13:04:41] <archivist> abetusk, not sure the language is clean enough, you could read the rs274ngc.... sources of the interpreter
[13:06:42] <archivist> abetusk, but one was written as an experiment http://emc-developers.narkive.com/iIAhLI43/rs274ngc-bison-flex-parser-was-question-on-gcode-parsing
[13:09:34] <CaptHindsight> oussama: are you working with http://wiki.linuxcnc.org/cgi-bin/wiki.pl?Gremlin?
[13:10:11] <abetusk> archivist, thanks, that looks like it is or is close to the thing I want
[13:10:22] <archivist> some russian site pops up for gremlin_readraw is that spelled correctly?
[14:01:01] <developper> Hello , i have decelopped a new interface Linuxcnc but when i try to run it i found this problem " missing handler gremlin_redraw" how can i solve it ? help me please.
[14:02:05] <CaptHindsight> developper: post the link to your git tree so that people can review what you are doing
[14:04:15] <CaptHindsight> developper: try to stick to one nick or people might think that you are trolling
[14:33:16] <nikre> i have normally open limit switches and i get "joint X on limit switch error" when i trigger the limit switch manually. is this expected?
[14:33:29] <nikre> i invert limit switch pins
[14:33:53] <nikre> is this due to noise?
[14:54:04] <Cromaglious> I was getting that on a loose wire... i believe so
[15:36:43] <Crom> wow heekscad is slow
[15:36:57] <XXCoder> and crashy in my experence
[16:36:38] <CaptHindsight> new troll "gremlin_readraw"?
[16:54:54] <MacGalempsy> dang it is hot in the shade
[16:56:48] <MacGalempsy> a more organized stack
[16:56:49] <MacGalempsy> https://www.flickr.com/photos/58181938@N03/
[16:57:07] <MacGalempsy> got to figure out where to put that edm! lol
[16:57:18] <MacGalempsy> thinking the computer needs to move
[16:57:21] <Deejay> gn8
[16:57:40] <MacGalempsy> good night Deejay
[16:57:50] <Deejay> :)
[17:11:09] <Tom_L> what's the motor bracket for?
[17:11:55] <LeelooMinai> MacGalempsy: O, a real mountain bike with SID and all:)
[17:13:26] <MacGalempsy> Tom_L: the tetris shaped looking one?
[17:13:43] <Tom_L> ya
[17:13:49] <MacGalempsy> LeelooMinai: you want to buy the white one?
[17:14:02] <LeelooMinai> MacGalempsy: lol, no, I have my own:)
[17:14:24] <MacGalempsy> Tom_L: that is for the printer I am building, while learing to CNC machine
[17:15:16] <MacGalempsy> that one will have a nema 17 and an incorporated pillow block for the acme screw to seat into
[17:15:36] <MacGalempsy> they are connected with a GT2 belt
[17:27:00] * Tom_L blows the 5'oclock whistle, punches the timecard and plants his arse in the easy chair
[17:27:32] * Tom_L forwards all calls til tuesday PM
[17:27:47] * JT-Shop has entered happy hour
[17:28:02] <Tom_L> it's a very happy place ehh?
[17:28:06] <Cromaglious> yeah time for another cup of tea
[17:30:26] <Cromaglious> ubuntu installed now on the T60 now to try heekscad heekcam on it..
[17:31:12] <Tom_L> is it any good?
[17:33:00] <Crom> model name : AMD Turion(tm) X2 Dual-Core Mobile RM-72
[17:33:14] <Crom> 1050Mhz is not fast enough for heekscad
[17:34:33] <Crom> trying on the T60 2.33Ghz dual core
[17:35:03] <Tom_L> i meant heekcad cam
[17:35:29] <Crom> dunno yet.. can't get it to do anything since the computer is too slow
[17:35:36] <CaptHindsight> Crom: maybe you can buy time on the super computers at Sandia or Los Alamos
[17:35:58] <Tom_L> i offload my light work to it
[17:35:59] <Crom> or buy a octocore 4Ghz machine..
[17:36:35] <CaptHindsight> does Heeks only run as a single thread?
[17:37:19] <Crom> don't think so
[17:39:13] <Crom> I don't have a windows machine available to me. Wife and housemate have one
[17:40:18] <Crom> so no fusion 360 for me
[17:50:20] <MacGalempsy> sounds like a good reason for a windows virtual box
[17:52:26] <XXCoder> virtual box dont always work
[17:52:44] <XXCoder> fusion 360 needs bit more video memory than it can provide, expecially if 3d accerated
[17:53:09] <XXCoder> I asked devs severial times but they ALWAYS say "256 mb is all you need"
[17:53:21] <CaptHindsight> does virtulbox have GPU pass-through?
[17:53:22] <XXCoder> yeeah like 512k ram is all you need lol
[17:53:48] <XXCoder> capt nope because having 2 OS control gpu memory and features will never work
[17:54:10] <XXCoder> same reason virtual os needs its own image of hard drive
[17:56:23] <XXCoder> CaptHindsight: HOWEVER
[17:56:26] <XXCoder> there is a way
[17:56:47] <Crom> I'm trying to CAM a AR-15 lower with z0 being the top of the area where the trigerr control group goes and Y0 is the center of the rear take down pin and X0 is the left side of the receiver edge. Mag well is i Y+ Z- is down, X+ goes to the right side of the receiver using a 1" long 1/8" flat end mill
[17:56:49] <XXCoder> add another video card, and use vbox feature to allow os use that, and host os cannot use that one
[17:59:12] <CaptHindsight> XXCoder: the answer is YES
[18:00:54] <XXCoder> well havent found a way to do so and host still have access to video
[18:02:15] <CaptHindsight> semantics
[18:03:17] <CaptHindsight> watch out for the "gremlin_readraw"
[18:07:07] <MacGalempsy> most of the GPU stuff in Fusion is cloud based, or so I have been led to believe
[18:07:37] <XXCoder> surpising works well lol http://picpaste.com/pics/IMG_20160909_153412-qW5B5Rr5.1473460720.jpg
[18:07:45] <XXCoder> nylon puck with hole + battery
[18:07:53] <XXCoder> it rotates just fine
[18:08:00] <MacGalempsy> heres the edm I just picked up on ebay for $10.5k
[18:13:16] <Crom> git cloning heekscad and heekscnc
[18:20:21] <XXCoder> MacGalempsy: pics or didnt happen heh
[18:20:25] <CaptHindsight> LOL https://hardware.slashdot.org/story/16/09/09/2042212/smartphones-can-steal-3d-printing-plans-by-listening-to-the-printer
[18:21:04] <MacGalempsy> http://www.ebay.com/itm/Hansvedt-EDM-/172288425749?hash=item281d30bf15:g:~0sAAOSwdzVXm8FX
[18:21:13] <CaptHindsight> "a smartphone on a bench about 8 inches away from a 3D printer could allow someone to reconstruct a simple object being printed with 94 percent accuracy." that better than what a 3d printer can with a native file
[18:21:27] <XXCoder> capt old story but funny indeed
[18:21:40] <XXCoder> interesting mac
[18:21:56] <MacGalempsy> that one doesnt have the x/y/z dro
[18:22:09] <MacGalempsy> got mine for 600 :D
[18:22:54] <XXCoder> ah interesting machine
[18:23:22] <MacGalempsy> one machine closer to making vintage land cruiser plastic parts
[18:24:07] <MacGalempsy> they had some cool small silicon injection machines down there.
[18:24:26] <MacGalempsy> someone could make some nice phone cases with that
[18:26:01] <XXCoder> I suppose
[18:26:15] <XXCoder> but then theres like one less than infinity phone case makers
[19:44:01] <Cromaglious> I SURVIVED!!!! step daughter drove accoss town and back..
[19:44:16] <MacGalempsy> life is good
[19:45:18] <Cromaglious> she's 18 and got her license just after she turned 18 10 months ago... still not the greatest driver
[19:45:31] <roycroft> so
[19:45:43] <roycroft> 2towns have put out a seasonal cider
[19:45:47] <roycroft> unfilted pumpkin cider
[19:45:50] <roycroft> unfiltered
[19:45:57] <roycroft> i'm expecting extreme yum
[19:46:11] <Cromaglious> roycroft, wooo might have to get some of that for my wife
[19:46:27] <roycroft> are you in my part of the world?
[19:46:37] <Cromaglious> I'm in socal..
[19:46:50] <roycroft> i'm not sure they distribute that far south
[19:47:03] <roycroft> have you seen 2towns before?
[19:47:06] <Cromaglious> I'll be in Santa Cruz next weekend
[19:47:25] <Cromaglious> gotaa take the girl back to school
[19:47:39] <roycroft> you have a hippie daughter?
[19:47:43] <Cromaglious> heard of it.. I don't drink
[19:47:52] <Cromaglious> pretty much
[19:48:00] <roycroft> or is she a surfer girl?
[19:48:30] <Cromaglious> Faire brat... more at home in a bodice and peasant skirt
[19:48:45] <roycroft> if i were forced to work in the bay area i'd probably commute from santa cruz
[19:48:56] <Cromaglious> I'm from Richmond
[19:49:16] <roycroft> fortunately i don't feel compelled in any way to deal with that part of the world on a regular basis :)
[19:49:43] <Cromaglious> I'm up there 2-3 times a year
[19:49:52] <roycroft> it's an ok place to visit
[19:50:00] <roycroft> but way too crazy to live there
[19:50:08] <roycroft> even eugene is too big for me
[19:50:11] <XXCoder> http://picpaste.com/pics/IMG_20160909_171520-Tq0c1jtX.1473466729.jpg
[19:50:14] <XXCoder> its made
[19:50:14] <Cromaglious> folks are in Richmond, brother is in Walnut Creek and my step grandkids are in Sacremento
[19:50:33] <Cromaglious> I love the wilamette valley
[19:50:34] <XXCoder> its surpising pretty good though it has bad bridging issues on bottom
[19:50:50] <roycroft> i'm wishing i could scrape up $2 million really quick
[19:50:59] <XXCoder> you can do it slow way?
[19:51:03] <roycroft> there's a nice 300 acre piece of property nearby for sale
[19:51:06] <XXCoder> that'd be better than mosy people LOL
[19:51:08] <roycroft> it's a ranch
[19:51:12] <roycroft> has a big house and a shop
[19:51:20] <roycroft> and no neighbors anywhere nearby
[19:51:24] <Cromaglious> only took my grandma till the age of 61 to become a millionaire
[19:51:25] <roycroft> 'cuz it's 300 acres :)
[19:51:44] <roycroft> well i don't have much time to lose then
[19:51:51] <Cromaglious> win the lottery... ;/
[19:51:55] <XXCoder> lol
[19:52:01] <roycroft> that would require buying lottery tickets
[19:52:10] <Cromaglious> $4 a week for me..
[19:52:37] <Cromaglious> friday saturday superlotto, megamillions, and powerball
[19:52:48] <Cromaglious> could do $8 a week...
[19:53:05] <roycroft> i picked up a bunch of steel today
[19:53:10] <roycroft> most of it stainless
[19:53:19] <roycroft> one piece of allegedly 304 flat was rusty
[19:53:23] <roycroft> the guy swore it was 304
[19:53:33] <roycroft> i made him go get a magnet
[19:53:35] <roycroft> and the magnet stuck
[19:54:00] <roycroft> it was the end of the day and he wanted to go home
[19:54:21] <roycroft> he'd have gotten out of there faster if he had just gotten me the right piece when he realised he had grabbed the wrong one
[19:54:33] <roycroft> instead of arguing with me
[19:54:43] <XXCoder> rusty stainless steel lol
[19:54:53] <roycroft> oh, i've seen rusty stainless steel before
[19:55:02] <roycroft> i've made ss rusty before
[19:55:05] <roycroft> but you have to try
[19:55:06] <XXCoder> sure but then it should rust very slowly
[19:55:12] <roycroft> it doesn't happy by just sitting around in a steel yard
[19:55:23] <XXCoder> happen?
[19:55:31] <roycroft> yes, happen
[19:55:43] <XXCoder> lol ok
[19:55:44] <roycroft> spray hot caustic on it and scrub it with a steel wool pad
[19:55:51] <roycroft> it will be rusty the next morning
[19:56:01] <XXCoder> well can do it to start rust for looks then stop it
[19:56:11] <XXCoder> I guess it would stay looking rusty but barelu rust any more
[19:56:21] <roycroft> once it starts rusting it will keep rusting
[19:56:28] <roycroft> after all, it is almost entirely iron
[19:56:46] <roycroft> once some iron is exposed to the surface it will continue to rust
[19:56:50] <XXCoder> oh really? interesting
[19:56:55] <roycroft> you can remove the rust
[19:56:57] <XXCoder> well gonna run later
[19:57:00] <roycroft> but then you have to repassivate it
[19:57:04] <Cromaglious> laterz
[19:57:07] <roycroft> usually you soak it in hot nitric acid
[19:57:16] <roycroft> ciaoder
[22:10:41] <XXCoder> got question
[22:10:53] <tiwake> got tablet
[22:10:55] <XXCoder> if i want a spindle that can be fully controlled by computer
[22:11:11] <XXCoder> speed ranging from sy 1000 rpm to 10,000 rpm or something
[22:11:24] <XXCoder> but keeping torque pretty good
[22:11:32] <XXCoder> what is best spindle for that
[22:11:45] <XXCoder> pwm to me it seems it loses power as it slows down
[22:11:46] <tiwake> XXCoder: rotation position? "rotate 90 degrees and hold for 3 seconds"?
[22:12:22] <XXCoder> no, rpm as well as stop and go
[22:12:37] <MacGalempsy> how about a large AC servo?
[22:12:52] <MacGalempsy> like 5hp or 10hp
[22:12:59] <XXCoder> 52 mm diameter?
[22:13:04] <tiwake> 10k RPM is pretty fast
[22:13:16] <XXCoder> yeah i would be fine with less
[22:13:42] <MacGalempsy> mine is a 2hp ac servo. the only bad part is that the PID control is all in the VFD, no external control
[22:13:42] <tiwake> there is a 2,000hp motor in the shop I'm working at... 900RPM :P
[22:14:15] <tiwake> I can hide inside the copper coil windings
[22:14:16] <MacGalempsy> my twin turbo is about 500hp and varies between 0 and 7krpm
[22:14:17] <tiwake> lol
[22:14:26] <XXCoder> there seem to be no VFD thats 52mm in diameter
[22:14:39] <XXCoder> only 80 mm or larger which is little big for my machine
[22:15:23] <XXCoder> nice http://ecmweb.com/content/understanding-variable-speed-drives-part-1 reading now
[22:15:29] <MacGalempsy> http://cncmakers.com/cnc/controllers/Spindle_Motor_Driver/Electric_spindle_motor.html
[22:15:35] <MacGalempsy> there is a 48mm
[22:15:41] <MacGalempsy> and 65
[22:16:09] <MacGalempsy> wouldnt you want to use a gear box or something?
[22:16:17] <MacGalempsy> or a belt pully?
[22:16:18] <XXCoder> I wonder too
[22:17:11] <MacGalempsy> my spindle motor is 5000max, but the spindle turns at 7500 due to gearing. I am led to believe through the literature that there is a belt in there
[22:18:04] <tiwake> XXCoder: if you want, I could ask my shop what VFD they use for the motors here
[22:18:05] <XXCoder> odd, torque loss at low rpm range is not menioned as con for PWM
[22:18:21] <tiwake> XXCoder: they all do that
[22:18:29] <tiwake> drop torque at low RPM
[22:18:32] <tiwake> by a lot
[22:18:46] <XXCoder> enough that it wouldnt be able to say cut alum or?
[22:18:53] <tiwake> oh not that much
[22:19:26] <XXCoder> I doubt my 3d printed clamp would be able to stand up to such abuse anyway but yeah
[22:19:26] <tiwake> haas VF1 we had, had issues reaming a 1.5" hole at 200RPM
[22:19:31] <tiwake> tended to stall out
[22:19:32] <tiwake> heh
[22:19:44] <tiwake> 7.5hp rated motor
[22:19:54] <XXCoder> btw http://picpaste.com/pics/IMG_20160909_171520-Tq0c1jtX.1473466729.jpg
[22:20:24] <XXCoder> all those fillets make for surpising very strong clamp
[22:20:30] <XXCoder> but then its 3d printed lol
[22:21:14] <gennro> XXCoder, http://www.ebay.com/itm/ER11-Chuck-CNC-500W-Spindle-Motor-52mm-Clamps-Power-Supply-Speed-Governor-/322233221172?hash=item4b0698c034:g:Xn0AAOSwdzVXtqfk
[22:21:39] <XXCoder> thats pretty good gen
[22:21:58] <gennro> I wouldn't worry so much about being controlled by a computer
[22:22:02] <gennro> for a smaller machine
[22:22:23] <XXCoder> 0 to 15k rpm
[22:22:30] <MacGalempsy> the 3d printing class at the local tech college paid like $500 for a clamp like that for a router.
[22:22:42] <XXCoder> MacGalempsy: whaa
[22:22:50] <MacGalempsy> and there was a whole machine shop right next door
[22:22:53] <MacGalempsy> with daily classes
[22:22:57] <gennro> you can get PWM DC motor controllers to control those air cooled 52mm spindles
[22:23:02] <XXCoder> dang I can print some up for SAY $100 EACH OR SOMETHING LOL
[22:23:14] <XXCoder> oops
[22:23:24] <MacGalempsy> lol. I told the guy to call me if he needs any more special parts like that
[22:23:24] <XXCoder> gennro: yeah? got example link?
[22:23:31] <gennro> xxcoder one sec
[22:23:34] <MacGalempsy> told him I would do it for 400. lol
[22:23:36] <XXCoder> aw mac lol
[22:23:53] <XXCoder> mac though that clamp is my own design
[22:24:00] <gennro> http://www.ebay.com/itm/282098587686?_trksid=p2055119.m1438.l2649&ssPageName=STRK%3AMEBIDX%3AIT
[22:24:00] <XXCoder> I used fillets a LOT
[22:24:05] <MacGalempsy> no I mean like the one in the ebay article
[22:24:06] <XXCoder> made for strong design
[22:24:30] <tiwake> XXCoder: just get one of these http://www.artcotools.com/compete-nsk-e3000-series-spindle-system-60-000-rpm.html
[22:24:38] <gennro> that controller allows for a 1-10v input to control speed
[22:24:42] <XXCoder> gen so basically my tb6560 -> this pwm controller -> spindle
[22:24:52] <MacGalempsy> wow
[22:25:05] <MacGalempsy> what are you cutting?
[22:25:08] <XXCoder> 60k? thats nuts. my grinder is very slow compared to that
[22:25:09] <MacGalempsy> engraving?
[22:25:18] <tiwake> hehe
[22:25:32] <tiwake> to be fair, they also sell gear reducers
[22:25:37] <tiwake> 16:1
[22:25:39] <MacGalempsy> i was thinking about just using my air dremel
[22:25:49] <tiwake> dremel is junk
[22:25:58] <gennro> yup
[22:25:58] <MacGalempsy> unfortunately, there is only like 5gln in the compressor
[22:25:59] <XXCoder> no price
[22:26:05] <tiwake> price is ~3k
[22:26:08] <XXCoder> which means I cant afford it
[22:26:08] <tiwake> USD
[22:26:13] <MacGalempsy> dremel was used as a generic name
[22:26:16] <XXCoder> like I said... LOL
[22:26:30] <tiwake> did a lot of research
[22:26:41] <MacGalempsy> my air dremel was like $30 at harbor frieght. lolo
[22:26:48] <tiwake> thats pretty much the best platform to build a rotary engraving machine off of
[22:26:51] <XXCoder> my dermel is 1/3 that mac
[22:26:57] <XXCoder> its also 1/3 of quality
[22:27:05] <tiwake> oh much less quality
[22:27:16] <tiwake> I've used one of those NSK brushless motors
[22:27:17] <XXCoder> tiwake: no my dermel as compared to mac's
[22:27:22] <tiwake> oh gosh they are so nice
[22:27:53] <tiwake> super quiet, well balanced
[22:28:03] <MacGalempsy> it is a high quality one. Chicago Pneumatic. Hmmm must be made in USA? lol
[22:28:51] <XXCoder> I have actual dermel (dermel company one)
[22:28:55] <XXCoder> its very good indeed
[22:29:14] <MacGalempsy> ive had one and the little nylon gear seams to melt
[22:29:34] <MacGalempsy> once the edm gets here, i'm making an aluminum coupler
[22:29:37] <XXCoder> mines first generation so probably good quality, before they made all that qyality cuts
[22:29:49] <XXCoder> all companies seem to do that
[22:30:03] <XXCoder> including food ones "lets do one oz less"
[22:30:30] <MacGalempsy> http://www.ebay.com/itm/NSK-Planet-800-Super-Precision-High-Speed-Jig-Grinder-up-to-90-000-rpm-/112127982940?hash=item1a1b593d5c:g:8vUAAOSw6n5XuaV0
[22:30:37] <MacGalempsy> that 60k one is slow as shit
[22:31:46] <MacGalempsy> http://www.ebay.com/itm/NSK-Planet-2000-Super-Precision-High-Speed-Jig-Grinder-up-to-200-000-rpm-/112124792038?hash=item1a1b288ce6:g:mZcAAOSw6n5XuaoK
[22:31:50] <XXCoder> 90k rpm jeez
[22:31:54] <MacGalempsy> that 90k rpm is even slow
[22:33:40] <XXCoder> so its not at 90 as supposed to be at?
[22:34:40] <MacGalempsy> why would someone need 200k rpm?
[22:35:37] <XXCoder> gear down for mad hps? :P
[22:35:38] <XXCoder> dunno
[22:36:03] <XXCoder> (no I got no idea why people use "mad" for lots)
[22:37:08] <MacGalempsy> so the shop reorganization is not done... that edm is 60x60x89, so the computer workstation needs to be modfied
[22:37:38] <MacGalempsy> wife is complaining about never parking in the garage again
[22:37:57] <XXCoder> build a shop
[22:38:14] <MacGalempsy> dont have the $$ right now
[22:38:29] <MacGalempsy> maybe if I sell the stuff I just bought at auction
[22:38:37] <XXCoder> the hardest part is floor
[22:38:44] <MacGalempsy> https://www.flickr.com/photos/58181938@N03/29536722886/in/dateposted-public/
[22:38:50] <XXCoder> rest you can literally buld it yourself for couple thousand bucks
[22:39:02] <MacGalempsy> so the workstation will likely move, maybe even inside
[22:39:17] <MacGalempsy> and the edm goes right in the corner. hope there is enough room
[22:39:46] <MacGalempsy> need to sell a couple of dirt bikes :D
[22:40:04] <MacGalempsy> well, they could go into the shed for the winter
[22:41:22] <XXCoder> http://www.ebay.com/itm/12V-24V-48V-110V-5V-110V-Max-10A-DC-Motor-Speed-Control-PWM-MACH3-Speed-Control-/291547916446
[22:41:24] <XXCoder> HMM
[22:41:28] <XXCoder> looks better with heat sink
[22:41:56] <XXCoder> but is spindle you linked me to dc also, and will work with it?
[22:41:57] <MacGalempsy> wow. that is pretty cheap
[22:42:19] <MacGalempsy> no idea
[22:42:32] <MacGalempsy> the 90k motor?
[22:42:36] <XXCoder> heck no
[22:42:44] <XXCoder> http://www.ebay.com/itm/ER11-Chuck-CNC-500W-Spindle-Motor-52mm-Clamps-Power-Supply-Speed-Governor-/322233221172
[22:43:37] <MacGalempsy> I would be worried about crappy bearing in that chinese motor
[22:43:53] <MacGalempsy> especially at such high rpm
[22:43:59] <XXCoder> well you linked me it lol
[22:44:07] <MacGalempsy> not that one
[22:44:33] <XXCoder> oh it was gennro
[22:45:01] <XXCoder> huh sale ends in 3 min lol
[22:45:07] <MacGalempsy> it just depends on what you want
[22:45:08] <XXCoder> just 4 bucks off whatever lol
[22:45:23] <MacGalempsy> you better jump on in
[22:45:33] <XXCoder> lol
[22:45:38] <XXCoder> yo gennro ?
[22:46:21] <MacGalempsy> http://www.zdnet.com/article/now-you-can-buy-a-usb-stick-that-destroys-laptops/
[22:47:45] <MacGalempsy> So tomorrow is the "local" makers faire, unfortunately the wife has an orchestra event for music class, so thats out of the question...
[22:51:47] <roycroft> usb sticks have always been able to destroy laptops
[22:52:01] <roycroft> you just need to pull the memory chip out and replace it with a small amount of thermite
[22:53:31] <MacGalempsy> gn8\
[23:39:38] <XXCoder> lol remember the sale?
[23:39:43] <XXCoder> it resumed after expire
