[00:00:05] <SWPLinux> no, 7:50AM flight, arriving around 9:something, which is too late for the morning sessions tomorrow
[00:00:20] <Jymmm> SWPLinux: they would put you in a hotel in LA for the night?
[00:00:49] <SWPLinux> if I asked for it, I bet they would. and dinner + breakfast too
[00:01:01] <Jymmm> eeeesh
[00:01:13] <atom1> 1st class?
[00:01:30] <Jymmm> SWPLinux: Yeah, free drink vouchers too
[00:01:39] <SWPLinux> might be first, you never know. see you

[00:12:24] <Connor> Why do people like belt vs gears on spindles ? Noise?
[00:13:35] <atom1> less backlash maybe?
[00:13:39] <atom1> noise too
[00:13:50] <Connor> Backlash on a spindle?
[00:14:08] <jdhNC> noise, speed, gear breakage
[00:14:10] <atom1> if you're tapping it's important
[00:14:13] <TekniQue> backlash can be important
[00:15:20] <Connor> I'm looking to see what will be upgraded and changed on my mill
[00:15:26] <jdhNC> everything?
[00:15:47] <Connor> Well, X and Y will get CNC'd first.
[00:15:53] <jdhNC> I was hoping grizzly would call or email friday and tell me my g0704 was shipping
[00:15:59] <Connor> then the Z, and then probably changing out the spindle.
[00:16:32] <jdhNC> I bid $260 on that white gavin
[00:16:38] <jdhNC> oops
[00:16:50] <Connor> huh?
[00:17:06] <jdhNC> I have an annoying tendency to type in the wrong channel
[00:18:05] <atom1> it can be entertaining sometimes
[00:47:07] <Connor> Okay, So, I want to upgrade my bed on my router.. I'm looking at two options.. build one from 80/20 or using a 24" x 24" alum plate and drilling and tapping it..
[00:47:09] <Connor> thoughts ?
[00:47:57] <jdhNC> plywood torsion box?
[00:49:41] <Connor> Huh?
[00:50:31] <jdhNC> rigid, flat, inexepensive table
[00:51:23] <Connor> I don't think that would be much better than the MDF one I have now..
[00:53:52] -!- ries [ries!~ries@] has joined #emc
[00:53:58] <Jymmm> I dont get it, build a new router? or table top for existing one?
[00:54:33] <Connor> Replace the MDF Table (spoil Board)
[00:54:46] <Connor> with Alum or 80/20
[00:54:51] <Jymmm> Ok, how does 80/20 fir into that picture?
[00:54:56] <Jymmm> fit
[00:55:15] <Connor> They have 1" x 3" with 3 T slots.. you bolt them together side by side..
[00:57:19] <Jymmm> If you bolt them together, you'll close off the opening to insert/remove bolts in the slots
[00:57:30] <Jymmm> Unless you mill an openng
[00:57:52] <Connor> They have T nuts that you can insert through the slot and twist.
[00:58:13] <Jymmm> desn't sound very strong, but ok.
[00:58:13] <Connor> You can also drill access holes in the sides and bolt them that way
[00:59:25] <Jymmm> I guess it's all really going to depend on what type of material you'll be using mostly.
[01:04:19] <jdhNC> stil need a spoilboard?
[01:05:08] <Jymmm> If you're milling wood and want less split out on the back side
[01:08:42] <Jymmm> jepler: you around by chance?
[01:12:24] <Jymmm> Plane jsut went from 30,000 ft to 6100 feet in 5 seconds! lol
[01:12:34] <Jymmm> Talk about a bumpy ride!
[01:13:16] <Jymmm> Also went from 198 to 280 MPH in 5s too!!!
[01:14:06] <atom1> wtf happened?
[01:14:26] <atom1> i bet that got homeland all stirred up
[01:14:29] <Jymmm> nose dive???
[01:14:55] <Jymmm> Oh now up to 391mph in 20s
[01:15:02] <Jymmm> and back up to 15oooft
[01:15:58] <elmo40> don't worry... I make parts for those planes ;)
[01:16:21] <Jymmm> I think it's just amazing that you can track a plane live like this
[01:16:46] <atom1> bud in seattle took his gps on a plane ride and logged it
[01:18:31] <Jymmm> now at 22K and 413mph
[01:19:32] <Jymmm> http://codepad.org/6SySaq7G
[01:20:52] <Jymmm> where in the hell do they get the data from?
[01:21:30] <atom1> who's pasting it?
[01:22:01] <Jymmm> just some website
[01:22:03] <atom1> 0 kts 34,000 feet
[01:22:06] <atom1> that's bogus
[01:23:40] <Jymmm> they even tell you when it was scheduled to leave the gate and when it actually did
[01:24:37] <Jymmm> * Arrival Gate Changed From 74 To 73
[01:25:05] <Jymmm> # Baggage Claim Changed To 1

[01:26:43] <atom1> i was rather impressed our pilot made up an hour inflight
[01:26:54] <Jymmm> heh
[01:27:01] <Jymmm> lead foot
[01:27:02] <atom1> i forget the flight now but it was in the south somewhere
[01:27:10] <atom1> he just smiled at me
[01:27:15] <elmo40> you can get tracking info from many different sites.
[01:27:17] <elmo40> http://www.flightstats.com/go/Home/home.do
[01:27:27] <atom1> he happened to be sitting in the lobby by us beforehand
[01:27:33] <elmo40> http://flightwise.com/flighttracking/
[01:28:30] <Jymmm> but where do they get the data from is what I want to know

[01:29:36] <elmo40> the airport?
[01:29:43] <elmo40> it is public knowledge.
[01:29:43] <atom1> maybe they're monitoring the flight data from the terminals
[01:30:17] <atom1> just like noaa data. you just gotta know how to translate it
[01:30:41] <Jymmm> atom1: You have a link to the raw flight data, like NOAA has?
[01:30:49] <atom1> no
[01:31:21] <Connor> Well.. right now, by bed IS my spoil board.. I normally put a 1/4" MDF over top of it...
[01:31:34] <Connor> If I use a Alum plate or 80/20.. I'll use do the same..
[01:31:41] <elmo40> don't spoil the bed!
[01:31:43] <Jymmm> I use 3/4"
[01:31:55] <Connor> My Bed is 3/4" MDF
[01:31:56] <elmo40> at work we use 2" Al ;)
[01:32:16] <Jymmm> my spoiler is 3/4"
[01:32:37] <Jymmm> screw messing with warping
[01:32:59] <Connor> What about your bed?
[01:33:13] <Jymmm> spoiler sits on 80/20
[01:33:20] <Jymmm> well clamps to it
[01:33:40] <Connor> solid? or just a 80/20 frame?
[01:33:51] <Jymmm> frame
[01:34:26] <Connor> okay, yea, see.. That's what I never understood.. Your bed == Spoil board.
[01:35:15] <Jymmm> t-nuts
[01:35:44] <atom1> http://www.fly.faa.gov/flyfaa/usmap.jsp
[01:35:44] <Connor> I have something like those.. They're designed for MDF though.
[01:35:55] <atom1> the flight ontime data would be airline specific
[01:36:21] <Connor> Insert Nuts..
[01:36:31] <Connor> and then I have 4 T-slots.
[01:37:21] <Connor> I want to replace with 1/2" Alum sheet drilled and tapped with 1/2" of MDF
[01:37:58] <Jymmm> atom1: DAMN that website is fast

[19:03:52] <anonimasu> I were looking at them before, it seems the digitals have 0.03 repeatability....
[19:03:53] <anonimasu> -_-
[19:04:56] <anonimasu> tho, my suspicion is that any chinese that claims 0.01 is lying.
[19:07:43] <archivist> .01 what!
[19:09:02] <anonimasu> mm
[19:09:24] <anonimasu> the "digimatic absolute" ones seem to be 0.01mm
[19:24:57] * anonimasu is damn close to ordering one NOW!
[19:27:26] * JT-Shop has several of the mitutoyo calipers and has yet to break one
[19:27:42] <anonimasu> im sick of china calipers
[19:27:48] <anonimasu> they never ever repeat worth crap

[19:28:56] <anonimasu> I think im not gonna buy the carbide jaw:ed one tho they are too expensive
[19:29:32] <anonimasu> err im not..
[19:31:51] <anonimasu> seems like all the china ones are extremely sensitive to external pressure
[19:32:47] <anonimasu> so if you measure and you press a bit too hard you get +/- 0.05
[19:33:47] <archivist> adjust gibs on them
[19:34:57] <anonimasu> how?
[19:35:09] <anonimasu> scrape it in shape again?
[19:35:19] <anonimasu> and make a insert to go inside?
[19:35:26] <archivist> adjuster screws
[19:35:36] <anonimasu> :)
[19:35:50] <archivist> often work loose
[19:36:04] <archivist> even on mitutoyo ones
[19:39:11] <anonimasu> I dont think my china ones have adjuster screws even
[19:42:21] <anonimasu> I love forums

[19:46:16] <anonimasu> I have only setup blocks for that
[19:46:38] <anonimasu> but, it seems like a easier way to buy a proper caliper then guess :)
[19:48:16] <archivist> one day they may make a caliper with force measurement so you know the pressure is the same as when on your calibration block
[19:48:33] <anonimasu> that would be nice

[20:01:06] <jdhNC> heh... new G0704 date is now May 20
[20:06:28] <Connor> Yea.

[20:24:20] <jdhNC> I'd prefer a heavier machine, but the heavier X3/SX3 have much smaller tables
[20:25:04] <Connor> jdhNC: FRom what I've read, Heavier X3 isn't better.. the open frame vs the BF20 style... BF20 style is much better.
[20:26:09] <Connor> JT-Shop: Yea.. I don't have a front end loader.. or a engine host or anything.. I'll have to barrow a furniture dolly to get it up my driveway.. then.. figure it out from there.. it'll have to be removed from the crate in my car port..
[20:26:21] <Connor> my shop is only 11' x 7'
[20:26:42] <jdhNC> I started to rent a bobcat today, but it turned out to be $145 for a half day
[20:27:36] <jdhNC> so I figured... me, my son, a wheelbarrow, some shovels... really bad decison
[20:27:53] <Connor> what was you moving ?
[20:28:00] <JT-Shop> it's not the equipment as much as improvise adapt and overcome
[20:28:02] <jdhNC> about 5 cubic yards of dirt
[20:28:21] <jdhNC> that stuff is heavy, and I'm old and decrepit
[20:28:23] <Connor> oh
[20:30:35] <archivist> just do it one bite at a time, same as eating an elephant
[20:35:35] <JT-Shop> yep
[20:35:50] <atom1> kinda like putting on a roof

[20:40:47] <Jymmm> You can plug in most anything to it (checking for onboard serial)
[20:41:19] <Jymmm> Oh shit, is DOES come with paraport, it's just a header
[20:41:30] <Jymmm> and serial too
[20:41:37] <Jymmm> hawt damn!
[20:42:05] <Connor> use PCI card though.. just in case you short something.. parport card easier to replace than whole mobo
[20:42:09] <Jymmm> and a TURBO SWITCH!!! WOOHOO
[20:42:20] <Jymmm> Connor: Sure =)
[20:42:40] <Jymmm> I have a dual paraport pci card around here somewhere
[20:43:20] <Jymmm> The only thing I can see missing is IDE

[21:17:28] <Jymmm> interesting.
[21:17:28] <Connor> Do you loose torque when using micro stepping ?
[21:17:38] <Connor> Jymmm: They have all kinds.
[21:17:58] <Connor> I use a external unit that you can just plug sata's into.
[21:18:03] <Connor> but, no IDE
[21:18:07] <MOGLI> yes torque is a problem... do you have any solution for it
[21:18:43] <Connor> Huh?
[21:19:01] <Connor> I was asking because I've been running at 1/2 stepping.. thinking of switching to 1/8 or 1/16
[21:19:05] -!- The_Ball [The_Ball!~The_Ball@123-2-12-83.static.dsl.dodo.com.au] has joined #emc
[21:21:05] <Jymmm> Connor: do you have a torque issue?
[21:21:18] <robin_sz> connor: the answer is ... yes and no ... steppers develop peak torque when a coil is fully energized, so when you start micro stepping there are points in the cycle where you are down to 70% of peak torque .. but you should not be running so cloes to torqu llimits anyway
[21:21:21] <Connor> Only when I increase the speed.
[21:21:25] <MOGLI> than its not a big problem i am using 1/32
[21:21:40] <robin_sz> Connor, what drives are you using?
[21:21:41] <Jymmm> and it's easy enough to switch to 1/8 and test it out. should smooth things too.
[21:22:07] <robin_sz> abd what voltage?
[21:22:43] <robin_sz> hello Jymmm
[21:22:50] <robin_sz> still around I see :)
[21:22:51] <Connor> I have a cheap Chinese TB6560.. Just made two mods to it.. Changed the cap from 330 to 1000pf to up the freq and removed the crazzy circuit that's suppose to reduce torque when no signle.
[21:23:00] <Connor> running at 24v..
[21:23:19] <robin_sz> quite low voltage, would explain the lack of torque at moderate speeds
[21:23:34] <Connor> after just removing the idler circuit.. I can push 200IPM
[21:23:41] <Connor> at 1/2 stepping.
[21:24:20] <Connor> these are 354oz-in torque steppers..
[21:24:36] <JT-Shop> holding torque
[21:24:43] * robin_sz nods
[21:24:43] <Connor> right.
[21:24:49] <Connor> holding torque.
[21:24:54] <robin_sz> at 24v that will fall off rapidly
[21:25:07] <robin_sz> whats max drive voltage with that board? 36v?
[21:25:18] <Connor> 32 or so..
[21:25:29] <robin_sz> consider buying some geckos?
[21:25:31] <Connor> or so I've read.
[21:26:14] <Connor> Why? It works.. I was just making these changes to get a little better performance out of it.. if I can put it in 1/8 stepping and still not have any missed steps.. I'm good.
[21:26:14] <robin_sz> there really is no substitute for volts when it comes to keeping torqu at high speeds
[21:26:23] <robin_sz> k
[21:26:47] <Connor> I was just wanting to know if using microstepping affected the torque.
[21:27:40] <Connor> also, what's the step time and step space do? I have those at 5000 each
[21:27:43] <robin_sz> can be the same as half stepping, but depepnds on the type of microstepping .. can be down to 70%
[21:28:19] <JT-Shop> good drivers like the Gecko203v morph from 10 microsteps at slow speed to full steps at high speeds
[21:28:27] <robin_sz> yep
[21:29:07] <Connor> I'll probably use Gecko's on the mill.. but, this is a little DIY MDF Router..
[21:29:08] <elmo40> lmao... FBI terrorist list includes a guy who used Linux :P http://qurl.org/V81
[21:29:28] <robin_sz> http://qurl.org/V81
[21:29:53] <JT-Shop> there is only so much silk you can get out of a sows ear...
[21:31:19] <robin_sz> damn right
[21:31:55] <JT-Shop> a G251 is a 203v but at 50v instead of 80v
[21:31:56] <Connor> okay, so what's step time and step space settings do in EMC ?
[21:32:00] <JT-Shop> $69
[21:32:37] <JT-Shop> step time is how long the pin is on and step space is how long it is off
[21:32:41] <jdhNC> are those any better than the 'digital' ones keling sells?
[21:32:47] <JT-Shop> unless you have your pins inverted

[22:09:32] <elmo40> so I guess the 1 from 1/3000 is a measurement of something. because there is a 0.5/3000 on ebay
[22:10:23] <elmo40> http://i.ebayimg.com/09/!CClZTt!!Wk~$(KGrHqZ,!lQEz+0SS5cDBNLm!ePnlw~~_3.JPG
[22:10:28] <elmo40> similar specs to that
[22:11:00] <elmo40> well, mine is the Beta 1/3000, that is Beta 0.5/3000, but they are both AC servos
[22:27:04] <Connor> Well.. I've got it up to 300IPM without loosing step MOST of the time... so, I'll setit down to around 200IPM and be done with it.. that's with 1/8 stepping.

[22:29:01] <Jymmm> Connor: what drives?
[22:29:23] <Connor> Using the Chinese crap board.
[22:29:38] <Jymmm> Connor: So they stall?
[22:30:03] <Connor> at 300IPM The Y stalled once since tweaking everything..

[22:30:31] <Jymmm> Gecko and OEM750's have mid-band compensation
[22:30:43] <Jymmm> to prevent stalling
[22:31:09] <Jymmm> OEM650 do NOT
[22:31:32] <Connor> Again, I'll use Gecko's on my mill.. this little thing doesn't warrant it..
[22:31:51] <Connor> I wanted to get the torque up so I could doe 1/8 vs 1/2
[22:34:48] <JT-Shop> to get the torque you have to raise the voltage

[23:54:53] <atom1> do you add an external resistor to the 203v for the current limit or is it a switch?
[23:55:05] <atom1> if so is 1% recomended?
[23:59:18] <Jymmm> atom1: what drive?
[23:59:28] <atom1> the gecko G203v
