[00:03:53] <XXCoder1> hey CaptHindsight what ya think http://hackaday.com/2014/07/11/400-diy-cnc-machine-is-surprisingly-simple/
[00:06:25] <CaptHindsight> XXCoder1: I like the glorified glue gun that used an actual $3 glue gun more
[00:06:44] <XXCoder1> lol yeah that clockwork glue gun is amazing
[00:06:55] <XXCoder1> I emailed guy to see if it would work with epoxy
[00:07:33] <CaptHindsight> you just use a syringe or a dispense valve for epoxy
[00:08:39] <CaptHindsight> or microvalves or inkjet printheads for higher speeds and higher res
[00:11:23] <CaptHindsight> I wonder if they use mills like that to make parts for these? http://autochunk.com/3224/2012/09/08/wooden-electric-cars-from-2012-china-eurasia-expo/
[00:11:50] <XXCoder1> probably some
[00:11:57] <XXCoder1> likely not bamboo parts
[01:16:07] <The_Ball> jdh, lol, just read up now
[02:02:38] <Deejay> moin
[06:49:30] <mutley_> mornink
[06:49:50] <mutley_> so, after all my issues, i made this http://imgur.com/ZVV7XSY
[06:50:56] <kfoltman> that's a lot of plastic dust! ;)
[06:54:27] <archivist_herron> radius and error ?
[06:54:47] <mutley_> heh i was more talking about the centricometer (if that is the correct name)
[06:54:54] <mutley_> radius and error?
[06:55:30] <archivist_herron> the radius of the tip from the rotation
[06:55:54] <archivist_herron> pk to pk deviation when you try it
[06:56:25] <mutley_> 50mm distance between hole centres
[06:56:35] <archivist_herron> often called a tramming tool
[06:56:41] <mutley_> aha ok
[06:57:14] <archivist_herron> if you google you see all the double dti versions
[06:57:36] <mutley_> not sure if it would have error? something im missing? i figure "if" the holes i drilled have error, it will be consistent as it is spun around in the spindle...this is made to go into the spindle
[06:58:26] <mutley_> the steel 8mm bar is dead straight
[06:59:08] <archivist_herron> when you travel a circle it should be +- 0
[07:01:25] <mutley_> yes understood. but the as i understand in my mind, the bar is dead straight, however even if it were bent, since it is in the spdindle any error in the bar would simple travel round as it turns in the spindle therby actually giving zero error
[07:01:55] <mutley_> however, if the bar itself were to rotate, lets say in a bearing, then yes, any error or deviation from straighness in the bar would result in an error
[07:01:57] <archivist_herron> yes the bar is a dont care
[07:02:01] <mutley_> would that understanding be right?
[07:02:47] <archivist_herron> the result shows the axis to table error
[07:02:50] <mutley_> or are you asking Radui and Error ie....what error do i measure on my spdinle with it? in which case id have to answer....dont know yet,
[07:03:11] <archivist_herron> not played with it yet!
[07:03:35] <mutley_> ok, but as a "tool" its a pretty fixed item, theres not really anything i need to adjust on it, its a fixed bar, the grub screws hold it in place so i can adjust
[07:03:52] <mutley_> no, ive only just made it and something was running onj the machine
[07:04:07] <mutley_> about to check it within the hour :) very excited....ooooo cant wait
[07:07:47] <jdh> mutely: what is the cam looking thing in the pic?
[07:07:57] <mutley_> i should add however, the penny dropped in relation to all the setup and adjustments, spindle squareness, perpendicity etc to the table, all makes perfect sense now
[07:08:12] <mutley_> cam looking thing? you mean in the black plastic?
[07:08:24] <jdh> yeah
[07:08:38] <jdh> looks like a rotating cam lock sort of something
[07:08:41] <Smidge204__> There's a half-gear in the upper left of the photo
[07:08:46] <jdh> or that
[07:10:18] <jdh> I need clamping/spoilboard inspiration
[07:12:20] <Smidge204__> ?
[07:13:34] <jdh> I have a similar table. I have not come up with a good method of mounting work and not damaging the table.
[07:14:33] <Smidge204__> Seems like a reasonable method there for smallish work - sacrificial part slightly larger than the work, T-bolt clamps...
[07:15:35] <jdh> 97.54% of the time I cut outside profiles
[07:15:43] <Smidge204__> Aaah
[07:16:13] <Smidge204__> Then it's either a vacuum table or you'll need to be aboe to cut a hole in the work and clamp through that
[07:16:39] <jdh> and plastic spoilboard gets burrs so it isn't flat afterward
[07:17:07] <jdh> I probably just need to make/buy a bunch more T nuts
[07:17:49] <mutley_> just stick something underneath, i often use little bits of 3mm ali plate dotted around the place, leaving space, tbh i dont see outside profiles being an issue, even hardboard or simialr wood
[07:18:10] <jdh> the only issue is having to clamp from the inside.
[07:20:59] <kfoltman> so, no problems using a t-slot table and step clamps?
[07:21:13] <kfoltman> I finally need to upgrade from foam pads :)
[07:21:15] <Smidge204__> Oh
[07:21:30] <jdh> probably not. It's just a pain
[07:21:31] <Smidge204__> How about using a shimplate that's smaller than the work?
[07:21:45] <Smidge204__> No problem with the tool putting burrs on it
[07:21:49] <kfoltman> jdh: ?
[07:22:04] <kfoltman> jdh: t-slot is just a pain?
[07:22:04] <jdh> moving clamps around is a pain.
[07:22:10] <jdh> <- lazy
[07:22:17] <kfoltman> yeah, but you have pain either way
[07:22:20] <Smidge204__> Then you could mill out some hollows on it and hook that up to a vacuum
[07:22:25] <kfoltman> foam pads = pain
[07:22:28] <jdh> I want to cut some parts that are close to the bounds of my working area.
[07:22:29] <kfoltman> vacuum bed = pain
[07:22:44] <Smidge204__> life = pain
[07:23:10] <kfoltman> a painless solution would probably be super expensive (vacuum bed with lots of independently switchable outlets)
[07:24:17] <kfoltman> moving clamps around doesn't sound *that* bad, in theory
[07:24:19] <jdh> the part has 4 holes in the middle so I can just do those first then bolt down. But I need something underneath to bolt to so I don't have to re-reference
[07:25:04] <Smidge204__> External jig?
[07:25:44] <jdh> I'll probably just drill through into the spoilboard and bolt to that.
[07:26:03] <kfoltman> but where will you put the nuts?
[07:26:16] <CaptHindsight> Enco 20% off everything day + free shipping
[07:26:16] <jdh> but, new machine, new spindle, and new plastic supplier so I have no idea on speeds/feeds either.
[07:26:48] <jdh> kfoltman: no nuts, just tap or screw into the spoilboard there.
[07:26:57] <kfoltman> oh
[07:27:04] <kfoltman> spoilboard made out of...?
[07:27:12] <kfoltman> alu? plastic? wood?
[07:27:17] <jdh> probably particleboard
[07:27:24] <kfoltman> can that be tapped?
[07:27:40] <jdh> if you don't want it to hold very long/well
[07:27:52] <kfoltman> I see!
[07:28:24] <jdh> wood screws are easier
[07:28:44] <kfoltman> right
[09:05:19] <Tom_itx> oh the woes of fixturing...
[09:05:56] <jdh> yeah, it would be a lot easier if you didn't have to hold things
[09:25:11] <CaptHindsight> or just think about how the part should be and it just appears, that would save a ton of time and effort
[09:32:05] <ssi> 07:57 < jdh> 97.54% of the time I cut outside profiles
[09:32:08] <ssi> jet cutting :P
[09:33:24] <_methods> CaptHindsight: i'm glad thats not reality because my back yard would be full of a bunch of shit that dosn't work
[09:33:56] <_methods> hell it's already full of that lol
[09:55:49] <PetefromTn_> Morning folks!!
[09:57:17] <ssi> eypete
[10:20:08] <PetefromTn_> ssi EYEMAN!
[10:26:01] <ssi> wat's up
[10:26:04] <JesusAlos> hi
[10:26:56] <JesusAlos> I looking for a kind of cooler stepper motor kit
[10:27:10] <JesusAlos> any body know something about?
[10:27:53] <PetefromTn_> managed to sell my Astro van been wanting to get another fullsize Bronco..
[10:27:57] <JesusAlos> In Spain are hot days
[10:28:13] <PetefromTn_> looked at several ragged out trucks that the owners wanted crazy money for.
[10:28:38] <PetefromTn_> Yesterday I saw a real pretty one on Craigslist for a good price. Unfortunately it was in Charlotte NC.
[10:31:28] <ssi> my laser optics just came :D
[10:33:28] <PetefromTn_> I called the guy and he was like I need to get this sold because I am having to move into an apartment and I am only allowed one space for my two cars LOL...
[10:33:47] <PetefromTn_> So I got it for $2k instead of the $3k he was asking.
[10:34:18] <PetefromTn_> Drives nice with ICE COLD AC!! Sounds awesome...LOL
[10:35:00] <PetefromTn_> Here is a pic... http://i150.photobucket.com/albums/s83/matospeter/Petes%20Bronco%20Adventure/IMG_20140714_091528_zps2961742e.jpg

[10:35:49] <PetefromTn_> http://i150.photobucket.com/albums/s83/matospeter/Petes%20Bronco%20Adventure/IMG_20140714_091628_zps9fdae3d9.jpg
[10:37:27] <cradek> that's a nice one. 94?
[10:37:57] <chris33> hello anyone from the uk?
[10:38:39] <PetefromTn_> yeah it is a 93. I got it for a song I think. It has 160k on it.
[10:38:48] <cradek> the 351?
[10:39:02] <PetefromTn_> Runs and drives pretty nice. and has brand new BF goodrich Ats on it.
[10:39:13] <PetefromTn_> yeah 351 with towing package.
[10:39:19] <cradek> my ex has a 96 with 140k on it, and it still runs like new
[10:39:31] <gonzo__> there are a few here from uk. But as long as you don't wanbt to aks me questions. I know nowt
[10:39:41] <PetefromTn_> I love these trucks. I used to have an 89 Eddie Bauer.
[10:40:07] <PetefromTn_> Cannot wait to get the little things fixed and get a tag on it and pop the roof off so I can cruise around.
[10:40:21] <cradek> good for work, but lousy as an only vehicle - way too big and thirsty
[10:40:30] <PetefromTn_> It sounds MEAN with the 351 and I think it might have an aftermarket exhaust on it..
[10:40:49] <PetefromTn_> meh I don't drive all that much so it is no big deal.
[10:40:52] <cradek> heh
[10:40:58] <cradek> bbl
[10:40:59] <PetefromTn_> We have a trooper as well..
[10:41:09] <PetefromTn_> it gets most of the driving long distances.
[10:41:19] <PetefromTn_> This one will be lifted here soon on 35's LOL
[10:41:23] <PetefromTn_> cay..
[10:41:25] <PetefromTn_> CYA..
[10:41:34] <gonzo__> I thought fuel was cheap in the US?
[10:46:09] <PetefromTn_> I just paid 3.25 a gallon on the way back home from Charlotte NC to Tennessee with the truck and my wife's trooper following me.
[10:48:03] <cradek> gonzo__: it is, but americans with 6L engines don't think so
[10:52:17] <PetefromTn_> 5.8 actually LOL
[10:52:42] <CaptHindsight> ssi: good enough for your project or are they gold painted chipboard?
[10:52:49] <ssi> dunno yet :P
[10:52:52] <zeeshan|2> lol fuel gets expensiv efast on the rx7
[10:52:54] <ssi> looks ok so far
[10:52:58] <zeeshan|2> i get like 10 mpg on it
[10:53:00] <ssi> the mounts are cheap, but they look like they'll work
[10:53:08] <ssi> mirrors do look like silicon
[10:53:17] <ssi> haven't unwrapped the lenses yet
[10:53:49] <CaptHindsight> that was quick shipping, China Post is ~ 1 week longer
[10:53:56] <ssi> yeah I paid $30 for ems
[10:55:33] <CaptHindsight> but I still wait longer for Fedex smartpost when using Amazon and shipped from the US
[10:55:38] <zeeshan|2> http://azr.cdnmedia.autotrader.ca/5/photos/import/201406/0218/4609/3446a581-cf93-460b-ad4a-fd0c3fed1c43.jpg?w=800&h=600
[10:55:40] <zeeshan|2> does this look better
[10:55:40] <zeeshan|2> or
[10:55:49] <PetefromTn_> zeeshan|2 I would not mind having one of those RX7's they are sweet cars..
[10:56:06] <zeeshan|2> http://azr.cdnmedia.autotrader.ca/5/photos/import/201406/1215/5734/1c3521aa-59b0-4c7d-8a0a-589e35b49482.jpg?w=800&h=600
[10:56:22] <zeeshan|2> PetefromTn_: they dont make good daily drivers though
[10:56:35] <zeeshan|2> at least not for me :P
[10:56:36] <syyl> i love the ridicioulus airduct on the subarus :D
[10:56:43] <PetefromTn_> Not a big fan of the WRX... it would not be a daily driver either..
[10:56:50] <syyl> it looks all the time like this
[10:56:51] <syyl> :O
[10:56:58] <zeeshan|2> PetefromTn_: im planning to buy either one of these
[10:57:00] <zeeshan|2> as a daily driver
[10:57:03] <zeeshan|2> they make great daily drivers!
[10:57:07] <zeeshan|2> 27mpg
[10:57:10] <zeeshan|2> 265hp
[10:57:15] <zeeshan|2> AWD
[10:57:18] <zeeshan|2> perfect for the winter
[10:57:25] <ssi> I had a golf R last year
[10:57:30] <ssi> like a wrx but FAR nicer :)
[10:57:32] <PetefromTn_> I think they are kinda ugly.
[10:57:41] <zeeshan|2> white one
[10:57:43] <zeeshan|2> or grey one!
[10:57:48] <zeeshan|2> i like the grey one but it has more miles on it
[10:57:53] <zeeshan|2> but it has wide fenders
[10:57:57] <ssi> the wrx and evo X are both really cheap cars wrapped around an expensive drivetrain
[10:57:59] <syyl> i think i go for a subaru forester as next car
[10:58:00] <ssi> the R was much more refined
[10:58:03] <ssi> plus way goddamn faster
[10:58:47] <PetefromTn_> I'll just drive over it with my big bronco LOL...
[10:58:48] <ssi> but alas, I sold it
[10:59:05] <ssi> to buy a 57mpg diesel :P
[10:59:13] <zeeshan|2> the golf r comes with a haldex awd system
[10:59:17] <zeeshan|2> which is really a 4wd system
[10:59:21] <zeeshan|2> not full time awd
[10:59:28] <zeeshan|2> from what i've seen in tests
[10:59:51] <zeeshan|2> the 'quattro' ones are full time awd
[10:59:54] <zeeshan|2> or 4motion
[10:59:55] <ssi> it's electronically controlled viscous center diff
[11:00:04] <ssi> it can be made fulltime, and the balance adjusted
[11:00:10] <syyl> mhm
[11:00:20] <PetefromTn_> sounds like lotsa stuff to break man....expensive stuff.
[11:00:26] <syyl> we beat the crap out of a golf 4motion back in the army ;)
[11:00:36] <ssi> PetefromTn_: fast ain't cheap :P
[11:00:45] <zeeshan|2> who wants to drive an old ass pos
[11:00:48] <zeeshan|2> thats slow these days
[11:00:49] <zeeshan|2> not me
[11:00:55] <zeeshan|2> i've done that enough with my 03 eclipse
[11:00:55] <syyl> it was "ok" :D
[11:00:57] <zeeshan|2> slow ass pos
[11:01:05] <zeeshan|2> though it's served me well!
[11:01:07] <zeeshan|2> 400,000 km
[11:01:28] <zeeshan|2> if it wasn't so rusted to shit, i'd consider keeping it
[11:02:23] <PetefromTn_> ssi I did not tell you about my trip to meet some locals the other day did I...
[11:04:21] <ssi> no
[11:06:35] <PetefromTn_> I was invited to an audio DIY meeting with some guys in Knoxville. Went to this guys house and he had a whole crapload of custom build audio speakers, amps, etc. etc. quite a few nice commercially made bits too. We listened to some amazing music on everything from LPs, to high definition CD,s to reel to reel, to you name it. '
[11:06:41] <PetefromTn_> It was really interesting.
[11:07:58] <PetefromTn_> Got to meet a couple local fellows who are gurus of speaker technology and amps design. One of them is the guy who designed the Bazooke tube for car audio guys. He is also responsible for quite a few patented speakers for home audio and has many awards for car audio tournaments as well. Really cool guy.
[11:09:19] <PetefromTn_> Also met this one guy who is a guru of tube amps and spoke quite a bit about those too. Both of these guys invited me to their homes to experience their custom built audio stuff. Cannot wait to see what they have. Some really nice guys too..
[11:12:53] <ssi> nice
[11:52:11] <ssi> https://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-xap1/t1.0-9/10407468_10100428305664522_2026491756060572455_n.jpg
[11:52:23] <ssi> https://fbcdn-sphotos-a-a.akamaihd.net/hphotos-ak-xpf1/t1.0-9/10385468_10100428305669512_308744044102259593_n.jpg
[11:55:16] <jdh> that's some Z height
[11:56:08] <zeeshan|2> nice
[11:59:35] <marmite_> http://valapuro.se/~marmite/warez/musik/stor.png i have a really huge scan :D
[12:00:52] <ssi> jdh: "some"?
[12:01:21] <jdh> some massive
[12:01:34] <ssi> there's like 2" of Z :P
[12:01:43] <ssi> and it's not motorized
[12:01:49] <ssi> marmite_: way too big :P
[12:01:53] <jdh> height, not adjustment
[12:02:00] <marmite_> ssi: :D yeah
[12:02:03] <Tom_itx> ssi, agreed
[12:02:06] <marmite_> well i wanto cad so
[12:02:13] <marmite_> so thought that a huge is better then to small :D
[12:02:16] <ssi> hehe
[12:02:32] <ssi> jdh: no I'm saying there's 0-2" between the nozzle and where the bed will be :P
[12:02:35] <Tom_itx> if you want to show it make it small
[12:04:21] <Tom_itx> ssi, how thick is the material you will be cutting?
[12:04:31] <Tom_itx> is 2" enough?
[12:04:53] <IchGuckLive> hi all
[12:05:13] <IchGuckLive> hi JesusAlos
[12:05:26] <IchGuckLive> today last bullrun with a big blood toll
[12:07:19] <ssi> Tom_itx: yea i think 2" should be plenty
[12:07:21] <ssi> hey ich
[12:07:59] <IchGuckLive> ;-9
[12:08:08] <ssi> IchGuckLive: https://fbcdn-sphotos-a-a.akamaihd.net/hphotos-ak-xpf1/t1.0-9/10385468_10100428305669512_308744044102259593_n.jpg
[12:08:12] <ssi> IchGuckLive: https://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-xap1/t1.0-9/10407468_10100428305664522_2026491756060572455_n.jpg
[12:08:56] <IchGuckLive> realy nice co2 setup
[12:09:01] <ssi> it's getting there :)
[12:09:09] <ssi> still a lot of variables to figure out
[12:09:12] <IchGuckLive> keep your air flow oil free
[12:09:14] <ssi> mostly mirror/tube mounts and alignment stuff
[12:09:39] <ssi> I probably should get a small air pump to dedicate to the laser
[12:09:42] <ssi> rather than trying to use shop air
[12:09:47] <IchGuckLive> the lense shoudt handle some offset
[12:10:10] <Tom_itx> ssi, this is for a laser?
[12:10:13] <ssi> Tom_itx: yeah
[12:10:20] <Tom_itx> for some reason i was thinking plasma
[12:10:25] <IchGuckLive> are you going for timingbelt at 0.1-0,254mm step
[12:10:40] <Tom_itx> thanks to the H U G E png i gotta reboot now
[12:10:54] <ssi> IchGuckLive: well for starters I'm using direct drive timing belt, MXL belt with 20 tooth pulleys, and it works out to 0.008"/step, which is kinda too big
[12:11:15] <ssi> about 0.2mm?
[12:11:25] <ssi> I may design some belt reductions for it tho
[12:11:51] <IchGuckLive> my laser point is 0.1mm
[12:11:55] <ssi> I saw a pretty nice design, lemme find it
[12:12:03] <IchGuckLive> that works out fine for path mode
[12:12:14] <ssi> https://lh5.googleusercontent.com/-BbDuItj7Znw/UuoQa1HvqWI/AAAAAAAALbk/MORKitksLl4/w1394-h785-no/IMG_20140128_215425129_HDR.jpg
[12:12:16] <IchGuckLive> but on picture you need 3/4 overlap
[12:12:31] <ssi> I'm probably going to be doing mostly path cutting
[12:12:44] <IchGuckLive> if you go 1/2 you got darker pictures w
[12:13:04] <IchGuckLive> thats very impressive
[12:13:09] <ssi> yeah looks pretty nice
[12:13:11] <Tom_garage> zlog
[12:13:12] <ssi> I can probably make something like that
[12:13:41] <ssi> I need to get the 3d printer set back up
[12:13:46] <ssi> make those spacers, as well as some cable chain
[12:13:54] <IchGuckLive> are you able to get the lense moved toward part for pont diameter correction
[12:14:23] <ssi> yeah the head has a couple inches of travel, the lens can move up and down relative to the head bounce mirror
[12:14:31] <IchGuckLive> 3D printer is good on 0,254mm as filament is big
[12:14:53] <ssi> so what I'm picturing is that the lens will focus the spot to some fixed distance below the nozzle
[12:14:55] <IchGuckLive> ssi think over a distance calibration
[12:15:07] <ssi> and then the nozzle gets moved down til it's that height above the material
[12:15:11] <ssi> set it with a feeler gauge or something
[12:15:13] <ssi> that about right?
[12:15:16] <Tom_itx> ssi did you machine those or print them?
[12:15:24] <ssi> Tom_itx: the belt reductions? they're not mine
[12:15:29] <Tom_itx> oh
[12:15:30] <IchGuckLive> for cut yes
[12:16:00] <IchGuckLive> on laser engrave you got at high power within 0.5mm problems n focus
[12:16:03] <ssi> Tom_itx: I want to make something similar... I will probably plasma cut the aluminum, then manually mill the precise parts like bearing bores, and 3d print the spacers
[12:16:24] <ssi> IchGuckLive: I don't follow
[12:16:28] <IchGuckLive> ok
[12:16:37] <IchGuckLive> cut is ok
[12:16:38] <Tom_itx> i'd machine the spacers to make sure they're as nice as the rest of it
[12:17:08] <ssi> Tom_itx: 3d printed is fine... thickness tolerance will be pretty good, they're lightweight, and not structural
[12:17:16] <Tom_itx> heck, machine the back side as one piece with the pocket
[12:17:22] <ssi> wasteful :)
[12:17:32] <ssi> and I don't have a cnc mill
[12:17:41] <Tom_itx> i thought you did
[12:17:43] <ssi> nope
[12:17:52] <ssi> I have everything else, but no mill
[12:17:53] <ssi> it's sort of sad
[12:17:59] <Tom_itx> it's high time...
[12:18:02] <ssi> yeah well... hehe
[12:18:07] <ssi> I have a g0704 that I started converting
[12:18:12] <ssi> but it's a long way from done
[12:18:44] <Tom_itx> is that a stepper driver board in the pics?
[12:18:50] <ssi> yeah
[12:18:52] <ssi> again, not my picture :)
[12:18:54] <Tom_itx> must be from some reprap thing
[12:19:05] <Tom_itx> are those nema 17 or 23?
[12:19:06] <ssi> but I remember seeing that particular board at maker faire and talking to the guys that make it
[12:19:09] <ssi> 17
[12:19:18] <ssi> I'm going to try to run this machine on 17s
[12:19:18] <Tom_itx> maybe a bit small... who knows
[12:19:27] <ssi> I ordered some 65ozin keling nema17s
[12:19:28] <Tom_itx> get those good ones at least
[12:19:39] <ssi> if they are sluggish, I'll upgrade to some short 160oz 23s
[12:19:57] <ssi> I wish nema 17 size servos were common and inexpensive!
[12:20:12] <ssi> if I had servos I wouldn't worry about reductions, I'd just get good encoders
[12:20:13] <Tom_itx> http://www.aliexpress.com/store/product/5pcs-NEMA17-78-Oz-in-CNC-stepper-motor-stepping-motor-1-8A/704350_554160664.html
[12:20:15] <Tom_itx> 78 in oz
[12:20:23] <Tom_itx> alot of reprappers use those
[12:21:11] <Tom_itx> about as cheap as you can find
[12:21:17] <ssi> yea I have some similar motors
[12:21:38] <ssi> I'm mostly underwhelmed by them being driven by reprap hardware
[12:21:41] <ssi> pololus etc
[12:21:48] <ssi> I ordered some proper drives and I'm gonna run them at 48V
[12:21:55] <Tom_itx> good
[12:21:56] <ssi> I'm hoping that peps them up quite a bit :)
[12:22:02] <ssi> if not I'll get 23s
[12:22:09] <Tom_itx> most of the drivers i've seen in reprap are underpowered imo
[12:22:15] <ssi> but the 23s on my plasma table are WAY overkill, and that's a much heavier machine
[12:22:25] <ssi> I can run that machine at 3000ipm
[12:22:26] <ssi> heh
[12:22:37] <Tom_itx> yeah, you're not gonna have alot of force on x and y
[12:23:11] <Tom_itx> is it also reduced?
[12:23:21] <ssi> sorta
[12:23:33] <ssi> when I originally built it, it was all rack and pinion with 1" pinions and 3:1 reductions
[12:23:35] <IchGuckLive> 23 is good
[12:23:37] <ssi> homebuilt
[12:23:42] <ssi> I rebuilt the X axis recently and made it belt drive
[12:23:45] <ssi> and now it's not reduced
[12:23:47] <ssi> but it really needs to be
[12:23:51] <IchGuckLive> with some gearing most powerfull
[12:23:57] <ssi> Y axes are still rack and pinion
[12:24:01] <IchGuckLive> at woarm a masterpice
[12:24:55] <ssi> Tom_itx: have you seen any inexpensive chinese servo motors with encoders?
[12:25:00] <IchGuckLive> im on 30:1 and still big speed
[12:25:04] <ssi> seems like there's tons of steppers, but not many servos
[12:25:12] <IchGuckLive> but 3:1 is a hell of speed
[12:25:35] <Tom_itx> ssi, no
[12:25:46] <ssi> about the only thing I'm aware of is the servo motors that keling sells
[12:25:52] <ssi> I've never seen one in person
[12:25:54] <Tom_itx> find a copier repair shop and get some
[12:26:03] <ssi> copier repair eh?
[12:26:35] <Tom_itx> http://tom-itx.no-ip.biz:81/~webpage/motors/motor3.jpg
[12:26:43] <Tom_itx> those had HEDS 9000 series on em
[12:26:47] <Tom_itx> from copiers
[12:26:48] <Tom_itx> free
[12:26:56] <ssi> nice
[12:26:59] <ssi> what voltage are they?
[12:27:02] <jdh> what's the rationale for mounting steppers 45 degrees?
[12:27:10] <ssi> jdh: no clue :P
[12:27:11] <Tom_itx> i'm not sure on the voltage
[12:27:23] <Tom_itx> they'll turn with a 1.5v battery though
[12:27:25] <ssi> jdh: also I dunno how he tensions those belts... personally I'd make a slotted nema mount so the motor can slide to tension belt
[12:27:49] <ssi> Tom_itx: I was thinking about buying some of these
[12:27:50] <ssi> http://www.ebay.com/itm/Parker-Nema23-Brushless-Servo-Motor-5000-line-Encoder-24v-Brake-Cables-CNC-/221452433393?pt=LH_DefaultDomain_0&hash=item338f97f7f1
[12:27:58] <ssi> not quite as cheap as I'd like, but they are probably quite nice
[12:29:55] <ssi> but like... something like this: http://www.walkerindustrial.com/V0050-211-A-000-Applied-Motion-Products-p/V0050-211-A-000.htm?shoppingcom
[12:29:59] <Tom_itx> they have a brake
[12:30:00] <jdh> I have a machine with some of those parkers
[12:30:06] <ssi> but chinese and $50 instead of $361
[12:30:16] <ssi> would be nice for these little belt drive tables
[12:33:56] <CaptHindsight> those ebay Parkers are a steal if they haven't been dropped or burned out
[12:34:09] <ssi> yeah
[12:34:18] <ssi> there's always a bunch of those parkers in the surplus place in california that I like
[12:34:35] <ssi> but I never buy any cause they're always just a bit too much money to spend for a "maybe someday I'll use these" purchase
[12:34:40] <CaptHindsight> I get them from a place up in Minnesota
[12:35:00] <ssi> last time i was there I bought a 74" piece of 25mm thk rail with four trucks for $200 :P
[12:35:26] <Tom_itx> l8r...
[12:35:28] <CaptHindsight> I tried to use the cheapo stuff from keiling but it's more trouble than it's worth even on proto machines
[12:35:34] <ssi> the servos?
[12:35:37] <ssi> I haven't tried them
[12:35:52] <ssi> I'm suspicious of them though, mostly because they don't come with encoders premounted
[12:35:55] <ssi> and that can be a hassle
[12:36:18] <ssi> I've used keling steppers and drives, and they're fine
[12:36:47] <CaptHindsight> or out of the box the screws holding them together are red oxide coated or stripped, loose etc
[12:37:38] <CaptHindsight> if he wasn't a half hour drive I wouldn't even bother
[12:38:44] <IchGuckLive> all the stuff is getting cheeper and cheeper as 3D printing hits the masses
[12:39:02] <ssi> yep
[12:39:04] <ssi> that's a good thing :P
[12:39:39] <CaptHindsight> Haier was working on a cheap FDM printer
[12:40:08] <CaptHindsight> they mass produce appliances
[12:40:21] <ssi> yea I have a bunch of their cheap window AC units :
[12:40:22] <ssi> :P
[12:41:09] <CaptHindsight> if your window AC was only $200 just thinks about how low cost they can sell a printer
[12:41:15] <ssi> yep
[12:42:02] <jdh> cheap ones are more like $120 aren't they?
[12:42:26] <ssi> oh shit
[12:42:38] <ssi> CaptHindsight: I put in a "make offer" on three of those parker motors for $125 each and he accepted it
[12:42:50] <jdh> heh
[12:42:52] <CaptHindsight> \0/
[12:43:00] <jdh> the cables cost twice that
[12:43:06] <CaptHindsight> yeah
[12:43:23] <ssi> now I need to hunt down some AMC brushless drives
[12:43:45] <jdh> maint. guy was snipping tie wraps and got the encoder cable. motor took off
[12:43:47] <ssi> 200V ones I guess
[12:45:49] <ssi> dammit they're always all over ebay
[12:45:51] <ssi> but none today
[12:46:01] <ssi> 60V drives for $30 ::P
[12:46:01] <ssi> http://www.ebay.com/itm/Advanced-Motion-Controls-AMC-Brushless-PWM-Servo-Amplifier-Analog-Drive-BE12A6B-/180798465469?pt=LH_DefaultDomain_0&hash=item2a186da5bd
[12:46:11] <CaptHindsight> I usually use them with the Gemini drives
[12:46:34] <ssi> I've got some experience with the amc drives and like them
[12:46:38] <ssi> but I'll look for geminis
[12:46:49] <ssi> http://www.ebay.com/itm/Parker-Compumotor-GV-U3-6-12-Gemini-Servo-Drive-Refurb-/170679973834?pt=LH_DefaultDomain_0&hash=item27bd51b7ca
[12:46:52] <ssi> that?
[12:47:27] <CaptHindsight> the geminis match and have profiles you just download
[12:47:39] <CaptHindsight> so very little to no tuning
[12:48:00] <ssi> so loop is closed in the drive?
[12:49:08] <CaptHindsight> yes, those, check the numbers to see if they have matching profile, you just connect over serial with free software
[12:49:31] <ssi> and then just send them position commands?
[12:49:58] <CaptHindsight> +- 5V
[12:51:04] <CaptHindsight> I run the encoder back to the mesa cards
[12:51:19] <CaptHindsight> it also runs to the Gemini for Hall
[12:51:29] <ssi> oh ok
[12:51:36] <ssi> so it's not closing position loop in the drive
[12:51:40] <ssi> just torque and maybe velocity
[12:51:44] <CaptHindsight> yes
[12:52:32] <ssi> what do you use for a power supply for those?
[12:52:50] <CaptHindsight> 120VAC
[12:53:12] <ssi> oh the drive is its own 170V supply isn't it
[12:53:18] <ssi> nice
[12:53:34] <CaptHindsight> yes, the bigger drivers are 240VAC
[12:53:43] <ssi> so the ones on ebay that are $75 are the U3E
[12:53:52] <CaptHindsight> I usually use the 340V servos
[12:53:52] <ssi> which is 3A continuous, 7.5A peak
[12:54:33] <ssi> that's too small a drive
[12:54:35] <ssi> Continuous Current = 5.5 amps
[12:54:36] <ssi> Peak Current = 16.6 amps
[12:54:38] <ssi> that's the motor specs
[12:54:44] <ssi> 170VDC
[12:54:53] <CaptHindsight> yeah, since it lower voltage
[12:54:58] <ssi> so I probably need a U6
[12:55:04] <ssi> which is 6A continuous, 15A peak
[12:55:44] <CaptHindsight> http://divapps.parker.com/divapps/emn/prior_version_compumotor/cat/english/pgs95_113_gem_servo.pdf
[12:55:55] <jdh> are there high voltage AMC drives?
[12:56:06] <ssi> yeah they make a 200V drive
[12:56:10] <ssi> but there's none on ebay right now :(
[12:56:18] <ssi> I bought three of them for the atrump mill conversion I did
[12:56:42] <CaptHindsight> yes U6's are 6A cont and 15A peak
[12:56:42] <ssi> http://www.ebay.com/itm/Parker-Compumotor-GV-U6E-Gemini-GV-digital-servo-driver-6-amp-1-7-kw-sinusodial-/371081161027?pt=LH_DefaultDomain_0&hash=item5666292943
[12:56:45] <ssi> that's a lot of damn money :(
[12:57:22] <IchGuckLive> ssi: from nema 23 to this is a big event
[12:57:45] <CaptHindsight> oh well, no ebay bargains today on the U6's :(
[12:57:49] <ssi> http://www.ebay.com/itm/Parker-Computmotor-GV-U3-6-12-E-NK-Gemini-Servo-RS-232-485-/201075651349?pt=LH_DefaultDomain_0&hash=item2ed10af315
[12:57:53] <ssi> I think those are U6s
[12:58:10] <CaptHindsight> http://www.ebay.com/itm/Parker-Nannifin-Corp-GV6-U12E-NK-Gemini-Compumotor-Servo-Drive-/281360072313?pt=LH_DefaultDomain_0&hash=item41825dfe79
[12:58:13] <ssi> if you look at teh last picture, it's stamped overtop of some text
[12:58:13] <ssi> heh
[12:58:30] <ssi> ooh that's not bad
[12:58:30] <CaptHindsight> $110
[12:58:43] <CaptHindsight> and from Florida
[12:58:51] <CaptHindsight> 1 day shipping for you!
[12:58:58] <ssi> put in a make offer on it ;)
[12:59:16] <ssi> I could build a hell of a machine with all that
[12:59:16] <ssi> heh
[12:59:37] <IchGuckLive> make some profit first
[12:59:44] <CaptHindsight> yes, I find better used on ebay than anything new even from China
[13:00:06] <ssi> yeah... I've retrofit a few machines with AMC drives, but
[13:00:11] <ssi> finding motors is always tough
[13:00:18] <ssi> I have some MCG servos from ebay
[13:00:35] <CaptHindsight> the worst that ever happened was that UPS dropped a $5K positioner on the servo and bent the shaft and broke the encoder
[13:00:37] <IchGuckLive> why not R7 from omron
[13:01:37] <CaptHindsight> I didn't notice it until I tried to tune it, when I pulled the cover off the encoder the lens was scuffed and I could see the bent shaft
[13:01:47] <ssi> that sucks
[13:02:17] <IchGuckLive> unpackig a broken part is always a miss
[13:03:05] <IchGuckLive> ordert 12pc of M880 and only 10 are good
[13:03:18] <CaptHindsight> but i found a replacement servo for $200 the next day, so still a bargain
[13:05:39] <IchGuckLive> its getting summer outside for at least one wek
[13:05:54] <ssi> yeah it's definitely summer here
[13:06:00] <ssi> I went sailing yesterday and neglected sunblock
[13:06:05] <ssi> and I'm in real bad shape heh
[13:06:36] <IchGuckLive> ssi: did you feel the free enrgie supply
[13:06:41] <ssi> yep
[13:06:59] <IchGuckLive> so there ishope for the US
[13:07:07] <ssi> no, no there's not
[13:07:19] <CaptHindsight> tomorrows high here is only in the 60's
[13:07:30] <IchGuckLive> ;-(
[13:08:07] <CaptHindsight> so probably 90's well into in September again like last year
[13:08:24] <IchGuckLive> By the way we are world Champion in soccer :-)
[13:08:32] <ssi> highs are only upper 80s this week apparently
[13:08:35] <CaptHindsight> congrats
[13:08:51] <CaptHindsight> IchGuckLive: did the party stop there yet?
[13:09:04] <IchGuckLive> no its almost intensive
[13:09:16] <IchGuckLive> Beer running as river flow
[13:09:25] <CaptHindsight> IchGuckLive: national holiday? :)
[13:09:37] <IchGuckLive> and frees has been empty this morning
[13:09:51] <IchGuckLive> in France today yes
[13:10:05] <IchGuckLive> all the french came over for shopping
[13:10:24] <IchGuckLive> and got the cheep beer and Bratwurst"
[13:10:42] <ssi> awshit I gotta call mesa and order some goods and services
[13:10:58] <CaptHindsight> only 11am there
[13:11:02] <ssi> yeah
[13:11:09] <IchGuckLive> Psw is on holiday
[13:11:22] <IchGuckLive> as wee all bought to mutch stuff
[13:11:28] <ssi> whole company? or just pcw?
[13:11:33] <IchGuckLive> he now can go to Hawai
[13:11:40] <CaptHindsight> just PCW I'm sure
[13:12:25] <IchGuckLive> they lost to jump in 3D printer boards
[13:12:36] <IchGuckLive> one fits all
[13:12:43] <IchGuckLive> like tb6560
[13:13:26] <IchGuckLive> if you look on 1-2-3 there are sold in thausends by the day

[13:15:54] <JesusAlos> luck was us
[13:16:22] <IchGuckLive> has been a long night here
[13:16:54] <ssi> ordered
[13:17:02] <ssi> she said that the mail may have already come today
[13:17:07] <ssi> knew I should have called earlier! :D
[13:17:52] <IchGuckLive> ssi: all you need is mesa
[13:17:58] <ssi> yes I know
[13:18:01] <ssi> I love them so much heheh
[13:18:08] <IchGuckLive> all you hate is postal
[13:18:34] <ssi> nah usps can get stuff all 2500 miles from pcw to my house in 2 days
[13:18:38] <ssi> for $6
[13:18:40] <ssi> it's pretty amazing
[13:19:24] <IchGuckLive> waited on saturday for a big deliver called this morning as paid for saturday postal arrived Mon10AM not as usal 2pm ;-)
[13:19:38] <postaL> wtf did i do w/ anything?
[13:19:43] <ssi> ahahaha
[13:20:07] <IchGuckLive> postaL: you are great but not the postman
[13:20:13] <postaL> :)
[13:20:26] <ssi> I like my postman
[13:20:27] <ssi> he's nice
[13:20:39] <IchGuckLive> here we got only female
[13:20:50] <IchGuckLive> dogs byte only males
[13:20:56] <postaL> lol
[13:20:57] <CaptHindsight> fee mail?
[13:20:59] <postaL> where is "here"?

[13:22:06] <zoni1983> hi is it possible to send command on serial port ie tools change command
[13:22:28] <zoni1983> IchGuckLive: hi
[13:22:30] <anarchos2> frig. dhl (well loomis express, who ever that is) attempted to deliver my package while i was here...
[13:22:46] <anarchos2> must be a ninja driver with the door knocking power of a flea
[13:23:21] <anarchos2> now i call them and they said it'll take 24-48 hours to redeliver :(
[13:23:32] <ssi> You can connect the power buses of Gemini GV-U3n/U6n/U12n/H40n drives in parallel, through the V BUS+ and V BUS- terminals. With the buses connected in parallel, regenerated energy from one drive will be used by the other drives.

[13:24:47] <IchGuckLive> anarchos2: thats the way live goes
[13:25:18] <IchGuckLive> im pretti shure that he drove by saturday with the part but did not knock
[13:29:57] <IchGuckLive> ok im off BYE for today O.O
[13:32:59] <zoni1983> IchGuckLive: i have a machine with 24 atc and spindle gear there are too many io needed so i wand to send a serial command to micro controller which will handle all the function
[13:33:23] <ssi> CaptHindsight: looks like these drives can either be configured as step/dir OR as +/-10V cmd
[13:37:16] <zoni1983> any body there
[13:39:09] <jdh> where?
[13:41:05] <CaptHindsight> ssi: they have stepper versions as well but I've never used them

[13:43:48] <CaptHindsight> ssi: some versions have an internal PLC and may also be programmed for closed loop and canned cycles
[13:43:50] <kfoltman> this is SVG only and seems to have plenty of rough edges, but, meh, it's free

[13:58:17] <ssi> nice
[13:58:25] <ssi> ha that guy's already got my servos in the mail
[13:58:26] <ssi> :D
[14:13:27] <JT-Shop> we had lunch in a 737 Saturday in Walnut Ridge Arkansas. The air base was a WW2 Army Air Corp training base
[14:14:42] <ssi> lol nice
[14:33:01] <JT-Shop> crap my spindle lock button broke
[14:34:32] <Loetmichel> JT-Shop: what a spindle?
[14:34:41] <Loetmichel> router?
[14:35:04] <Loetmichel> they have usually 2 flats on the shaft, fitting a 13mm or 15mm wrench
[14:36:18] <JT-Shop> Hardinge CHNC lathe
[14:36:45] <Deejay> dont push the button while the spindle is running
[14:36:47] <Deejay> ;)
[14:38:12] <JT-Shop> can't push it the air cylinder forces it out while the spindle is turning
[14:39:08] <Deejay> ah :)
[14:42:37] <JT-Shop> and that is how I just popped it out to put the collet
[14:46:17] <anarchos2> random question: once upon a time i came across a build log of a guy that made a box that had GPS and an LCD would display hints about the next location and eventually the box unlocked once it got to a certain location. anyone happen to remember seeing that?
[14:46:23] <anarchos2> my google skills are failing me
[14:48:05] <anarchos2> ah, found it. it's called a reverse geocache box.
[14:48:20] <Tom_itx> http://gizmodo.com/5384893/gps-puzzle-box-only-opens-in-one-specific-location
[14:48:21] <Tom_itx> or that
[14:52:34] <anarchos2> yeah, thanks, i think that it the one i was thinking of
[14:52:57] <anarchos2> it is apparently a popular thing to make
[14:54:19] <zoni1983> hi
[14:55:32] <zoni1983> i need help
[14:56:06] <micges> zoni1983: ask away
[14:59:13] <zoni1983> i have a machine with 24 tool atc and spindle gear thete are too many io required i wanted to know if there is a way to send tool change command via serial port to plc or miro controller to change tool or gear
[15:01:27] <JT-Shop> what control hardware are you using the parallel port?
[15:03:09] <zoni1983> can i comunicater with microcontroller via parallel port
[15:03:27] <Tom_itx> or get a mesa card to plug in the parallel port
[15:03:34] <Tom_itx> to give you much more io
[15:04:22] <zoni1983> i already have mesa 5i20 and 7i48
[15:04:36] <JT-Shop> what hardware do you have now controlling your machine?
[15:05:29] <Tom_itx> add a smart serial card for more IO
[15:06:27] <zoni1983> JT-Shop: i have 5i20 and 7i48 for hurco bmc10
[15:06:38] <Tom_itx> using linuxcnc i assume
[15:07:00] <zoni1983> yes using linuxcnc
[15:07:22] <Tom_itx> a SS card would be ideal for a tool changer i'd think
[15:07:35] <Tom_itx> 7i84 or such
[15:08:32] <JT-Shop> so you could add a 7i37 card and get 8 outputs and 16 inputs
[15:08:59] <JT-Shop> then you could use classicladder to do your tool change
[15:09:14] <JT-Shop> zoni1983, do you have to orientate the spindle to change tools?
[15:09:41] <zoni1983> i was thinking it would be very easy if a dedicated plc or micro controller is handling such funchtion as tool change
[15:10:02] <zoni1983> yes i have to orient spindle
[15:11:40] <zoni1983> i and using 2 7i37 , 32 inputs are not enough for tool change
[15:13:01] <JT-Shop> you could communicate with the plc with the parallel port if the plc was happy with 5v inputs
[15:13:17] <JT-Shop> most I've used want 120vac or 24vdc inputs
[15:14:13] <JT-Shop> or better use the 7i37 i/o to communicate with the plc
[15:15:02] <MrSunshine> just use a level converter? =)
[15:15:08] <zoni1983> JT-Shop: how to comunicate via 7i37
[15:15:11] <Tom_itx> JT-Shop, does the 5i20 support SSerial
[15:15:24] <JT-Shop> BCD or gray code
[15:16:07] <kfoltman> WEEEEEEEE http://i.imgur.com/1RPWRNn.jpg
[15:17:43] <zoni1983> can u give me example of bdc and gray code
[15:17:49] <JT-Shop> Tom_itx, I don't think so
[15:18:13] <Tom_itx> mine 7i43 / 47 didn't either but i added it
[15:18:26] <zoni1983> Tom_itx: no 5i20 does not have ss
[15:18:31] <Tom_itx> don't know if you can do that on the 5i20 or not
[15:18:43] <Tom_itx> you might ask PCW
[15:18:44] <PCW> The 5I20 supports sserial
[15:18:48] <JT-Shop> maybe if PCW was here
[15:18:50] <Tom_itx> :)
[15:18:53] <JT-Shop> oh there he is :)
[15:19:07] <ssi> all you gotta do is start talking about mesa gear and he appears
[15:19:09] <ssi> like magic :D
[15:19:11] <Tom_itx> that's the way i'd go i think
[15:19:13] <JT-Shop> lol
[15:20:01] <Tom_itx> the 7i84 gives you 16 out and 32 in
[15:20:21] <Tom_itx> split field voltage
[15:22:51] <PCW> Theres even a 7I77 config for the 5I20
[15:22:53] <PCW> (the 5I20's FPGA is not very big so there's a limit on sserial channels)
[15:23:27] <ssi> is there room on the 7i43 400k to do a single-sserial 7i77 firmware?
[15:23:47] <ssi> or maybe epp is too slow
[15:24:21] <PCW> 7I43-400 can have 16 or so channels but like you say the 1 MB/sec transfer rate takes it toll
[15:24:32] <ssi> yea not surprising
[15:25:21] <Tom_itx> i modded mine for it but i had to dump another function or i'd get synthesis errors
[15:25:24] <Tom_itx> timing...
[15:25:35] <PCW> at a KHz ist not terrible so a few channels is OK (most sserial devices are about 2 or 3 32 bit transfers each)
[15:25:58] <Tom_itx> i'd think it would be ideal for a tool changer
[15:26:15] <Tom_itx> not that timing critical
[15:26:32] <PCW> Yeah remote 24V I/O (good to 100 usec or so)
[15:40:39] * JT-Shop needs to cover up the shingles on the shop that I damaged with the back hoe yesterday
[15:41:08] <ssi> wopps
[15:41:35] <JT-Shop> yea the facia is a mess too
[15:44:31] <JT-Shop> I'm just glad is was not the dozer that hit the shop LOL
[15:47:21] * SpeedEvil needs to work out how he's going to attach the 20*1200*2400*150mm foam boards to his roof.
[15:54:39] <CaptHindsight> heh, ebay LPT cable 99 cents with $5.00 flat shipping shows up with $2.33 POSTAGE DUE
[15:56:28] <anarchos> url? i need a new lpt
[15:59:08] <CaptHindsight> was the last one, but I did find ot-5-Axis-CNC-Breakout-Board-for-Stepper-Motor-Driver-with-DB25-Cable-/111149514180 cable and breakout board for $15
[15:59:32] <CaptHindsight> http://www.ebay.com/itm/Hot-5-Axis-CNC-Breakout-Board-for-Stepper-Motor-Driver-with-DB25-Cable-/111149514180
[16:01:31] <anarchos> nice
[16:01:50] <CaptHindsight> not the longest cable but it works
[16:15:51] <MrSunshine> hmm for a "=0" funciton would "G92 X0" be more apropriate than "G10 L20 P0 X0" ?
[16:17:27] <Deejay> gn8
[16:17:29] <cradek> those do different things
[16:17:34] <cradek> what are you trying to do?
[16:18:26] <MrSunshine> well its on the pendant, to set the workpiece offset
[16:19:18] <MrSunshine> so i got a 0 0 0 (Homed position) then my workpiece might be at X20 Y20 Z12, so i jog there with the pendant then press the "=0" button to tell linuxcnc that its X0 etc
[16:20:24] <cradek> you probably want to use the g54 type fixture offset for that, which means using G10
[16:20:32] <MrSunshine> problem i have right now is that it actualy works with "G10 L20 P1 X0" but then all my "toolpaths" will be offset from the actual plot in axis gui =)
[16:20:58] <cradek> yeah, you have to either set it in AXIS or hit reload
[16:21:08] <MrSunshine> hmm
[16:25:35] <MrSunshine> but should i use "P0" or "P1" ? manual states that "P0" is the active coordinate system
[16:26:06] <cradek> well which one do you want it to set?
[16:27:02] <MrSunshine> i dont know :/ still kinda a noob on all this =)
[16:27:13] <MrSunshine> i guess the one that linuxcnc starts up with? :P
[16:27:52] <MrSunshine> G54 is that the "base" coordinate system ? =)
[16:29:48] <ssi> I'm gonna have to come up with some cleverness to figure out how to properly square this machine
[16:34:08] <MrSunshine> hmm P1 seems to set G54 so i guess thats fine that
[17:41:45] <CaptHindsight> http://www.ebay.com/itm/261392222841 hard to beat these for only $1.89ea IN:3V-40V, Out 1.25-30V 3A, buck only
[17:42:43] <ssi> dang
[17:43:07] <CaptHindsight> the digikey 100 pc price is $3.98ea just for the IC
[17:43:38] <CaptHindsight> even the 1K pc price is higher than the complete module
[17:43:40] <ssi> ordered ten of them :P

[17:45:41] <CaptHindsight> http://www.ebay.com/itm/231168922785 also handy for only $2.79ea 2 Channel DC 5V Relay Module With Optocoupler
[17:46:59] <CaptHindsight> even cheaper than the single channel relay board http://www.ebay.com/itm/331140197731
[17:50:16] <ssi> jeez I can use that too
[17:52:05] <CaptHindsight> http://www.ebay.com/itm/321302843841 4 channel with optos for $4.26 and 8 channel http://www.ebay.com/itm/131156821727 for ~$7ea
[17:53:48] <CaptHindsight> I ordered a bunch of each since I always seem to end up with some machine at 2am that needs just one more relay to get a feature working
[17:54:12] <CaptHindsight> or just handy for protos or testing things
[17:54:44] <ssi> yeah same h ere
[17:54:51] <ssi> I end up cobbling together annoying bullshit
[17:55:20] <ssi> I have a 3-32VDC opto switching 48V through dropping resistors to run a 48V dpdt mechanical relay to decouple my torch probe
[17:55:30] <ssi> because it's what I could build with crap I could get at frys and crap I had on hand
[17:55:45] <ssi> sry that should have read 24V dpdt relay
[17:56:39] <CaptHindsight> I wouldn't use them for a life support system, but they work :)
[17:57:35] <CaptHindsight> they all use the relays from this supplier http://www.songle.com/en/
[17:58:27] <CaptHindsight> they don't last as long as Omron or similar but they come in handy
[17:58:53] <ssi> bleh I'm having an annoying issue with the plasma machine
[17:59:08] <ssi> after a few pierces it'll stop in the middle of a job and fail to fire, flashing the parts in place fault LED
[17:59:20] <ssi> I'm thinking maybe it's oil/crud building up in the consumables
[17:59:31] <ssi> I'm about to try cleaning all the consumables very well
[18:01:23] <CaptHindsight> start there and hope that's it
[18:01:45] <CaptHindsight> intermittent problems are always a pain
[18:03:24] <Tom_itx> CaptHindsight, i got those buck regs _with_ a 7seg led for like $5 as well as some of the ones you posted
[18:03:51] <CaptHindsight> Tom_itx: does the LED show the output voltage?
[18:04:09] <Tom_itx> it's switchable
[18:04:12] <Tom_itx> in or out
[18:04:27] <CaptHindsight> so buck boost?
[18:04:34] <Tom_itx> buck iirc
[18:04:36] <Tom_itx> no boost
[18:04:46] <CaptHindsight> oh the readout
[18:04:49] <Tom_itx> but the display shows input or output
[18:04:51] <CaptHindsight> thats handy
[18:05:14] <Tom_itx> i got a handfull of each
[18:06:18] <Tom_itx> http://www.ebay.com/itm/LM2596-Voltage-Regulator-Module-DC-DC-Adjustable-Regulated-Power-Supply-Modules-/390883973942?pt=LH_DefaultDomain_0&hash=item5b02801b36
[18:06:25] <CaptHindsight> hmm, the 6mm to 1/8" collet adapter is too small to use for a 1/4" router! $2.19 down the drain :)
[18:06:29] <Tom_itx> beat that
[18:07:06] <CaptHindsight> US $1.51 current bid with free delivery
[18:07:19] <CaptHindsight> they should just put them in cereal boxes
[18:07:31] <Tom_itx> cracker jacks
[18:09:18] <ssi> lol
[18:09:52] <CaptHindsight> the buy it now is only $3.41
[18:10:01] <Tom_itx> just bid on it
[18:10:09] <Tom_itx> they have multiple entries for it

[18:11:09] <Tom_itx> i think that's closer to what i got
[18:11:13] <Tom_itx> 2 pushbutton
[18:11:27] <Tom_itx> one switches the display from input to output and the other blanks it
[18:12:19] <CaptHindsight> those LEDs must have a small micro in them
[18:12:29] <Tom_itx> possibly
[18:13:09] <CaptHindsight> unless it's hidden underneath
[18:13:29] <Tom_itx> the connectors cost that much
[18:14:31] <CaptHindsight> any connector that's popular there gets copied
[18:15:07] <CaptHindsight> you walk in or send a sample and for a blanket order or $1K you're in business
[18:16:25] <ssi> I really don't understand how they get some of this stuff so cheap
[18:16:47] <ssi> seems like raw materials cost exceeds the price of some of this stuff
[18:17:40] <CaptHindsight> when your whole shop is 2m^3 your overhead is pretty low
[18:18:29] <Tom_itx> i'd made one of those myself before i realized i could get them much cheaper there... http://tom-itx.no-ip.biz:81/~webpage/misc_stuff/5v_switcher.jpg

[18:20:26] <Tom_itx> ahh
[18:20:30] <CaptHindsight> some cheap micro with an AD
[18:21:00] <Tom_itx> looks like it's got a couple regs on it itself...
[18:21:38] <CaptHindsight> maybe a voltage reference
[18:21:51] <ssi> it's hilarious that it's cheaper these days to make a digital meter with a microcontroller and ADs than a mechanical meter movement
[18:23:19] <CaptHindsight> make a suit with those displays running with noise for input

[18:32:28] <JT-Shop> how about a scope
[18:32:45] <ssi> for laser power readout?
[18:32:56] <ssi> would need a current probe and that's a hell of an expensive 20mA panel meter ;)

[20:43:51] <anarchos> net remote-speed-medium or2.1.in0 input.0.btn-thumb

[20:44:55] <anarchos> net joy-x-jog halui.jog.0.analog <= input.0.abs-x-position
[20:47:42] <anarchos> there was two parts of the tutorial, first for setting the jog speed, second for actually jogging. first part does not work, second part does, but second part doesn't work if i comment out the first part...

[21:42:48] <XXCoder1> including the cable chain
[21:42:50] <ssi> I think i'm gonna put those parker motors I bought on the 704

[22:08:28] <XXCoder1> cool though
[22:10:02] <ssi> XXCoder1: they can be combined
[22:10:07] <ssi> that's why I ordered four lengths
[22:10:15] <ssi> 160" should be more than enough for the laser table
[22:11:26] <XXCoder1> aliexpress 5.92 bucks per meter
[22:12:15] <XXCoder1> other one 4.40 per meter free sh
[22:12:49] <CaptHindsight> if you can wait
[22:12:57] <XXCoder1> yeah thats flaw
[22:14:31] <ssi> I'm not big on waiting
[22:17:06] <CaptHindsight> I've been waiting for a cpu from Florida for a week. Fedex smartpost must be the slowest post as well
[22:17:15] <XXCoder1> lol
[22:17:33] <XXCoder1> my record for INSIDE usa only is over 30 days
[22:17:34] <jdh> the fedex part is fine, its when they drop it off at USPS that it disappers
[22:17:37] <XXCoder1> what a mess.
[22:18:19] <CaptHindsight> heh, yeah I've watched a few of my packages bounce around the country
[22:18:23] <ssi> heh
[22:18:44] <XXCoder1> it got lost, delayed 4 times, lost, then delayed again
[22:18:48] <XXCoder1> orbited couple cities
[22:18:49] <CaptHindsight> get within a few miles then suddenly pop up in Seattle or something
[22:22:48] <XXCoder1> heh worse from me was from my home to italy
[22:22:51] <XXCoder1> 45 days
[22:22:59] <XXCoder1> no idea why it was so damn slow
[22:23:10] <CaptHindsight> and then attempt delivery after 6pm to a business when it gets here
[22:23:47] <anarchos> my package is in alaska right now
[22:23:57] <CaptHindsight> US to the UK gets lost most often
[22:24:04] <XXCoder1> really?
[22:24:11] <XXCoder1> I sent so many there
[22:24:13] <XXCoder1> none lost
[22:24:43] <CaptHindsight> US to Germany asks the most questions about what is inside when it gets to their Customs Clearance
[22:25:14] <CaptHindsight> US to France gets lost most often before it leaves the US
[22:26:16] <CaptHindsight> I've people around London have to go their post office 2-3 times before it magically turns up in the corner or similar after 2-3 weeks
[22:26:18] <anarchos> i've never had a package get lost before. one time a package I sent to myself before I moved to New Zealand arrived after I got back (6 months later!)
[22:26:38] <XXCoder1> I think record is around 60 years
[22:26:46] <XXCoder1> lost postage lol
[22:27:03] <XXCoder1> it was delivered to wife, man it was for died years before
[22:27:15] <CaptHindsight> after 6-7 years I give it up as lost :)
[22:27:29] <XXCoder1> my hard drive I mailed is still lost
[22:27:34] <XXCoder1> 20 years now
[22:27:40] <XXCoder1> Probably get it back after I die
[22:27:58] <XXCoder1> well 18 years more like but yeah
[22:28:24] <CaptHindsight> I had UPS drive over one with a truck. They listed it as accidentally crushed by a truck :)
[22:28:46] <XXCoder1> ow
[22:28:56] <XXCoder1> my worse was one from germany
[22:29:07] <XXCoder1> it was bent in half. it wasnt made to be, being a box and all
[22:29:17] <XXCoder1> thankfully my $400+ order was all intact
[22:29:25] <XXCoder1> very rare parts
