[00:32:55] <Spida> anybody with experience of running a small router in an appartment?
[00:33:03] <Spida> acustic isolation?
[00:34:33] <danimal_laptop> if you use an actual palm router for the spindle, it's pretty loud
[00:36:08] -!- Turtl3boi has quit [Ping timeout: 252 seconds]
[00:36:19] <andypugh> I know quite a lot about noise isolation
[00:37:07] <danimal_laptop> nagging girlfriend?
[00:40:35] <andypugh> danimal_laptop: Babbit bearings are good. In fact I hope to start making them soon
[00:40:56] <andypugh> And the noise thing? That's my job, or was.
[00:41:08] <danimal_laptop> they aren't all that great for high speed machining
[00:41:37] <danimal_laptop> can't really hang with the speeds needed for carbide with a lot of materials
[00:43:13] <andypugh> Are you sure about that? I thought that part of the reason that they are used pretty much universally in crankshafts is that they cope better than rolling bearings at high peripheral speeds.
[00:44:32] <danimal_laptop> maybe with some clearance
[00:44:58] <danimal_laptop> but do you really want .002" bearing clearance in your spindle?
[00:45:19] <andypugh> At high speeds they need to be hydrodynamic, ie pressurised oil.
[00:45:20] <danimal_laptop> i thought it had more to do with the impact of the combustion
[00:45:42] <danimal_laptop> thats messy
[00:46:18] <andypugh> I am pretty sure that gearboxes hooked up to gas turbines (12" journals at 30,000 rpm) are always white metal.
[00:46:48] <danimal_laptop> ok, but for a 100 year old lathe, it sucks
[00:47:03] <danimal_laptop> from experience
[00:47:40] <andypugh> I would be surprised if they were white metal, they tended to use lapped spindles and brass/bronze
[00:47:49] <danimal_laptop> it's babbit
[00:47:59] <andypugh> Well, its
[00:48:13] <danimal_laptop> it's a lead-like metal
[00:48:14] <andypugh> a fun job to re-metal and re-bore :-)
[00:48:55] <danimal_laptop> definitely not brass or bronze
[00:49:24] <danimal_laptop> split bearings, you adjust tension with shims
[00:49:33] <andypugh> I admit that I have been looking for roller bearings in my next lathe, but it seems that the super-precision lathes used tapered (adjustable) plain bearings for a long, long, time.
[00:49:53] <Tom_itx> andypugh have you figured out how to make the babbit bearings yet?
[00:50:18] <andypugh> I am pretty much sure about all of it apart from sourcing the metal.
[00:51:26] <andypugh> My dad has a few ingots of Atlas grade MB, but I think that is for railway use, and probably lead-based rather than tin-based.

[00:54:22] <Tom_itx> http://www.uamet.com/p2.htm
[00:56:02] <mozmck> I think the old babbit always had lead in it.
[00:56:10] <andypugh> Lots of companies supply it, but I don't actually want 100kg.
[00:56:20] <Tom_itx> yeah
[00:56:21] <mozmck> You melt and pour it around the shaft.
[00:56:33] <Tom_itx> what lead tin mix is it?
[00:56:40] <Tom_itx> does it also have copper in it?
[00:58:03] <andypugh> For hogh speed and load they tend to be 88-92% tin, plus a bit of antimony and, yes, copper to give a nice crystal shape.
[00:58:16] <mozmck> Let me look, I have some articles on it. I helped a guy pour babbit for an old table saw.
[01:00:56] <mozmck> www.metalwebnews.org/ftp/bearing-book.pdf
[01:01:13] <Tom_itx> http://www.rotometals.com/Babbit-Bearing-Alloys-s/2.htm
[01:01:20] <Tom_itx> that lists several formulas
[01:01:52] <Tom_itx> cheap bars too
[01:02:22] <andypugh> 1927. A bit new-fangled for the application :-)
[01:02:45] <andypugh> But thanks, we might be printing and keeping that
[01:03:13] <mozmck> Yeah, apparently Mr Babbit did not use lead. All the stuff I've seen has lead and most of is good for pretty high speed. Our table saw bearings had lead in them and that is high speed and load.
[01:04:18] <Tom_itx> that one i linked lists 8 or 10 mixes
[01:04:26] <Tom_itx> some with no lead
[01:04:29] <mozmck> hmm, not 30,000 rpm though
[01:06:28] <Tom_itx> is antimony soft?
[01:06:52] <mozmck> I don't remember what antimony is...
[01:08:46] <mozmck> From Wikipedia: Antimony is a silvery, lustrous gray metal that has a Mohs scale hardness of 3.
[01:09:25] <Danimal_garage> i thought it was what you pay your wife after a divorce
[01:10:33] <mozmck> same hardness as copper.

[02:10:29] <Valen> we have a 3kw one and you can talk over it
[02:10:44] <Valen> though less so when its actually cutting

[02:11:39] <Tom_itx> that stuff you cast it in probably helps doesn't it?
[02:12:17] <Valen> i think we fired it up without that and it wasnt bad
[02:12:38] <Valen> we have a dent in a bearing as well which isnt helping the noise level ;->
[02:12:54] <Tom_itx> how'd that happen?
[02:13:04] <Valen> nfi, probably ran into something
[02:13:21] <Valen> we aren't exactly gentle ;-> we have broken alot of tools lol
[02:13:27] <Tom_itx> heh
[02:14:19] <Valen> but yeah, they aren't loud by themselves
[02:15:36] <andypugh> I have broken 2 tools tonight. One, sadly, never got to the workpiece, it hit a clamp due to inadequate safe-height. That's a brand-new tool which never got to cut metal, which seems sad.
[02:16:24] <Valen> http://www.youtube.com/watch?v=R_udQwy1hJk is it cutting some aluminium
[02:16:31] <Tom_itx> andypugh worth regrinding?
[02:16:45] <andypugh> Snapped off at the chuck
[02:16:51] <Tom_itx> aarg
[02:17:15] <Valen> you can hear the difference as i go from behind the plastic shower screen, i mean oh&s aproved safety screen to line of sight with it
[02:17:47] <Valen> http://www.youtube.com/watch?v=7ABNOf_fmEQ is it cutting glass, you can hear me talking around it
[02:17:51] <andypugh> Tom_itx: 2.5mm solid carbide, not a financial disaster.
[02:19:18] <Valen> we got something like 300 ~2-3mm carbide tools from china for ~$150 as i recall
[02:20:01] <andypugh> I still think you should use Valenite exclusively.
[02:20:11] <Valen> of course we broke the 6mm brand name performance coated roughing cutter in preference to one of those

[02:35:20] <Jymmm> Then hit the 24hr fried tofu and welding gas store!
[02:41:01] <danimal_laptop> yuck
[02:41:11] <danimal_laptop> i hope the welding place is open tomorrow
[02:41:30] <Tom_itx> if it's like here, maybe before noon but likely not
[02:43:56] <danimal_laptop> airgas is usually open on saturday i think
[02:44:27] <danimal_laptop> sucks, i had 3/4 of my enclosure welded, i was going to powdercoat it tonight
[02:45:39] <Tom_itx> argon?
[02:45:42] <Tom_itx> mix..
[02:46:00] <danimal_laptop> steelmix
[02:46:06] <danimal_laptop> for mig
[02:46:48] <danimal_laptop> i extended my enclosure 5" so i could add the touch screen
[02:47:40] <danimal_laptop> and keep the mpg and important butttons
[02:48:26] <danimal_laptop> i guess i can install ubuntu and play with touchy

[06:45:35] -!- ve7it has quit [Remote host closed the connection]
[07:17:07] <mrsun> is tapered gibs used to not have to have setscrews on the sides of the ways? :)
[07:17:25] <mrsun> like in areas where you cant have set screws for some reason .. be it space or whatever? :)
[07:31:59] <KimK> mrsun: Tapered gib pairs are far preferred over side setscrew gibs in any case except "lowest price". Tapered gibs can generate extremely powerful clamping forces (compared to setscrews) and can take much higher cutting force loads. They are also more stable because lower forces are reflected back to the adjusting rod.
[07:32:35] <mrsun> KimK, ahh ok =)
[07:32:46] <mrsun> good to know if i ever build something myself =)
[07:32:52] <KimK> You bet!
[07:34:05] <KimK> The shallower the taper the "better it works", until it doesn't do anything at all, lol!
[07:35:00] <KimK> Like everything in engineering, it's a compromise.
[07:42:46] <frysteev> hey guys,
[07:43:33] <frysteev> does anyone here have extern readouts on their machines?
[07:44:13] <Eartaker> frysteev, my screen gives me a readout....
[07:44:21] <frysteev> agreed,
[07:44:24] <KimK> on their EMC2 machines, you mean?
[07:44:26] <Eartaker> but I dont have a DRO if thats what ur asking
[07:44:48] <Eartaker> no need for DRO when you have CNC
[07:45:06] <frysteev> im looking at repurposing a readout, just wondeirng about how to get that data back out form emc, like maybe rs 232?
[07:47:44] <KimK> I would guess HAL should be able to do that. Creating your own component might make things easier, but I'll bet it could be done from stock components. What format does the display want?
[07:48:29] <frysteev> not sure yet, im reverse engineering somehting like this, basically making it into a dedicated remote for emc
[07:48:40] <frysteev> http://toronto.kijiji.ca/c-buy-and-sell-business-industrial-Heidenhain-TNC145-3-axis-CNC-controller-W0QQAdIdZ333498528
[07:48:56] <frysteev> i have access at one of those, that had a dead brain,
[07:51:50] <frysteev> just a project idea
[07:53:30] <frysteev> KimK: dont suppose you guys ever finish the resolver stuffs?
[07:53:36] <KimK> If you can figure out how they're driving the display, that might help, but it might not, as in cases where they let the microprocessor do row/column scanning (LEDs?) or it's some kind of odd driver chip (vacuum fluorescents?). I guess you could always keep the box and make a new board (even handwired?) with your "preferred" display. But it seems like a lot of work from here.
[07:54:06] <KimK> The DRO tab is so convenient, lol.
[07:54:49] <KimK> I believe Andy might have it finished, or 90% so?
[07:55:29] <frysteev> cool
[07:57:20] <KimK> (Where "it" is the Mesa 7i49 driver as far as using a resolver in "encoder mode" for position feedback.)
[07:57:37] <frysteev> only prob is my resolvers are the oppisite type i think grr
[07:58:31] <frysteev> i believe the mes 7149 is setup for transmitter resolvers and i have receiver resolvers
[07:58:46] <KimK> Mesa has a 7i49 manual online, I believe, so you could check the Mesa manual.
[07:59:02] <frysteev> i have read it,
[07:59:43] <frysteev> so the resolver board may not be any use... grr just my luck
[08:00:43] <KimK> Ah, OK, you've read it. What is the difference between transmitter and receiver resolvers? I don't think I've run across that distinction before for resolvers, only for selsyns, etc.
[08:01:46] <frysteev> http://en.wikipedia.org/wiki/Resolver_%28electrical%29
[08:01:59] <frysteev> half way down, i cant explain it better then that
[08:02:47] <frysteev> mine appear to be receiver resolvers, there is sine and cosine signals that travel to them, then a resultant that is computed

[08:11:54] -!- mhaberler has quit [Quit: mhaberler]
[08:15:15] <KimK> I would think you could use any ordinary resolver in either what they're calling a receiver or a transmitter circuit. One system drives the common coil (stator) and receives sin & cos results on the sin & cos windings. The other system requires driving the sin & cos windings 90 out of phase (not hard to do, since the freq never changes) and gets a result (two, really) on the stator. (Stator v. sin, stator v. cos). Dealers' choice, maybe?
[08:15:43] <KimK> Loetmichel: Good morning.
[08:16:57] <frysteev> it makes sence, but they list them as different physical types
[08:17:01] <KimK> Ask PCW when he's around, I'll bet he knows.
[08:17:54] <Loetmichel> KimK: i've seen both types of resolver, but the former more.
[08:20:30] -!- MattyMatt has quit [Ping timeout: 240 seconds]
[08:21:43] <KimK> The first one on the URL (transmitter?) mentions four leads, so you may be right. The second one (receiver?) doesn't say, but implies six leads, which is what I would consider "normal". When I wrote my descriptions above, I was figuring six leads for both, so I'm not sure about his four-lead resolver, I've not seen one of those in use.
[08:23:04] <KimK> (Not counting some kind of six-lead to four-lead commoning scheme, no fair, lol.)
[08:24:28] <Loetmichel> KimK: four lead and the 2 coils driven is usual i think
[08:25:20] <Loetmichel> i've seen 1 common and 3 coils or even internal sender electronics in the resolver
[08:26:27] <KimK> Loetmichel: Where does the output come from in the four-lead two-coil scheme? (It seems like one more coil is needed?)
[08:27:14] <Loetmichel> two coil?!?
[08:27:23] <Loetmichel> never seen that
[08:28:53] <Loetmichel> what i have seen (on time actually) is a 4 lead with one driven coil and one reciver coil and the second driven coil is gernerated inside the resolver by capacitor-phase-shift inside the resolver
[08:28:55] <KimK> I thought you said "four lead and the two coils driven is usual i think"?
[08:29:25] <Loetmichel> oh, sorry, that should state 4 lead and THREE coils
[08:30:24] <Loetmichel> one end of every coil commoned, the second end fed out
[08:31:05] <Loetmichel> ...
[08:31:18] <Loetmichel> i am not really awake 'til now i think
[08:31:33] <Loetmichel> 4 leads and two DRIVEN coils was correct.
[08:31:35] <frysteev> mine are 6 wire
[08:31:46] <frysteev> 2 driven coils
[08:31:52] <Loetmichel> two driven coils means one reciver coil, there are the 3 coils ;-)
[08:32:08] <KimK> OK, I agree, except I almost always see three coils as a six-lead device (in case all I/O is from small audio transformers and not commoned). Maybe that's a difference between USA and EU mfgrs?
[08:32:25] <Loetmichel> frysteev: if they are 6 lead you can use it both ways
[08:32:58] <frysteev> so i can use the 7149 theoretically when the mesa gurus on here finish their voodoo?
[08:33:06] <Loetmichel> one driven, two reciver AND two driven, one reciver, depending on your electronics

[08:33:44] <KimK> Loetmichel: Excellent, that's kind of what I suspected. Loetmichel & frysteev: Thanks for making me think about it!
[08:33:55] <KimK> frysteev: Yes, I believe so.
[08:34:00] <frysteev> woot!
[08:34:21] <frysteev> there is extension adapters for the mesa boards right?
[08:34:35] <Loetmichel> as a matter of fact i dont like the resolvers
[08:34:42] <frysteev> like if i wanted to have the 7149 remote of the anything i/o board?
[08:34:52] <KimK> If you're in doubt (and you don't have the 7i49 yet) maybe PCW will test one of your resolvers if you send it to him.
[08:34:53] <Loetmichel> i am more for direct drive and encoders for position feedback
[08:37:01] <Loetmichel> if one could live with a (max 120°) jump of the rotor at driver start a resolver isnt really needed, even for synchronous three phase servos
[08:37:36] <KimK> frysteev: In most (all?) cases, Mesa's servo boards must be within 5ft (max ribbon length) of the PC and its interface card. But the resolver cables can be as long as reasonably needed.
[08:37:55] <frysteev> cool
[08:38:18] <Loetmichel> hmmmm
[08:38:19] <frysteev> i SOOOO wanna use the resolver board cuz then i can get rid of 6RU of equipment in my conversion
[08:38:26] <Loetmichel> i dont own a mesa board.
[08:39:09] <Loetmichel> but 5 ft ribbon cable with ttl signals on it sounds like "shi* waiting to happen" to me.
[08:39:40] <KimK> You'll want a minimum of three shielded pairs, maybe with an overall isolated shield if you can get it, if not, OK.
[08:40:18] <frysteev> right now all the resolvers travel through one sheilded umbilical to the controller
[08:40:31] <frysteev> twisted pains but not individually shileded
[08:40:52] <Loetmichel> that sounds like the more reasonable cabling
[08:40:59] <KimK> Oh, that's right, you're reusing an existing install. Doh!
[08:41:16] <Eartaker> Loetmichel, what boaards do you have?.
[08:41:19] <Eartaker> boards
[08:42:13] <Eartaker> I have PMDX boards, Gecko drivers, and AMT102 encoders
[08:43:11] <Loetmichel> Eartaker: i use the lpt port ever since because on my private projects steppers are big enough
[08:43:38] <Loetmichel> ... but i had my share of EMI fuc* already
[08:43:44] <KimK> Loetmichel: Yes, 5 ft is said to be the max recommended. But apparently it's fine. Interlaced grounds are used. (That's why only 24 "raw" bits per 50-pin ribbon.)
[08:43:47] <Turtl3boi> hey man
[08:43:49] <Eartaker> I use the lpt port to but that goes to the PMDX board
[08:43:53] <Turtl3boi> sup Eartaker
[08:44:02] <Turtl3boi> sup Dr. Buchen
[08:44:04] <Eartaker> Turtl3boi, not shit
[08:44:10] <Turtl3boi> k
[08:44:14] <Eartaker> lol
[08:44:44] <Eartaker> Turtl3boi, U
[08:44:44] <Loetmichel> i even had to teach my bosses wife to NOT switch the flourescents of in the workshop if the Router is running... ALL motors would make a jump if switched back on :-)
[08:44:45] <Eartaker> ?
[08:44:59] <Turtl3boi> not much man, i'm stuffed still from thanksgiving leftovers
[08:45:11] <Eartaker> nice
[08:45:34] <Eartaker> Loetmichel, sounds like you need a larger cap for your DC power supply
[08:45:37] <Turtl3boi> still tryin to think about that ZX45 you told me about
[08:45:54] <Eartaker> ahh yeah or the PM45
[08:46:02] <Turtl3boi> yeah
[08:46:07] <Eartaker> I love mine
[08:46:21] <Loetmichel> no, that was gone as i plugged a booster/optoisolater board directly into the PC end of the lpt
[08:46:23] <Eartaker> you have to figure out what you want to do with it... then go from that
[08:46:42] <Turtl3boi> you *love* it?
[08:46:46] <Loetmichel> so it was directly coupled EMI not power supply related
[08:46:54] <Turtl3boi> you don't wish you had a bridgeport constantly?
[08:47:03] <Eartaker> lol I dont "love " it but def like the machine lol
[08:47:30] <Eartaker> Turtl3boi, maybe in the future but there is no way for me to fit one in my garage
[08:47:31] * Loetmichel has no "eisenschwein" (iron pig) machines.
[08:47:47] <Loetmichel> my machines are lightweigt and mostly made of WOOD
[08:48:11] <Eartaker> Loetmichel, http://www.eartaker.net/machining/milling/zx45.php
[08:48:14] <Turtl3boi> by "eisen schwein" he means anything not german or swiss made

[08:48:58] <Eartaker> nice
[08:49:02] <Loetmichel> Turtl3boi: no, by eisenschwein i mean anything above 1 ton of cast iron ;)
[08:49:13] <Eartaker> mine is 1/2 ton
[08:50:37] <Loetmichel> ... the one in the picture (which i build for my ex boss) has about 300 kg... for 1500*1020*160mm travel ;-)
[08:50:38] <Eartaker> Turtl3boi, I would love to have bridgeport or a clone but for me I know I have to move from this house in 3 years so there is no point right now for that size of a mill. Plus I don't need anything that big right now.
[08:51:42] <Eartaker> the largest thing I have made so far on it is a set of frame chassis for a 1/8 scale RC truck
[08:51:49] <Loetmichel> was a PIA to move out as ex-boss has sold the company, because the workshop was in the basement, and getting the macine bed out on the stairs with two ppl was "difficult" to say the least.
[08:52:02] <KimK> I'm going to wander off. Thanks for the chat, everybody.
[08:52:02] <Eartaker> http://www.eartaker.net/projects/tvps.php
[08:52:12] <Loetmichel> cu, KimK
[08:52:36] <Eartaker> Loetmichel, what do you make?
[08:52:45] <Loetmichel> hmm?
[08:52:50] <Loetmichel> with taht macine?
[08:52:53] <Eartaker> this is just a hobby for me
[08:52:57] <Loetmichel> that machine?
[08:52:59] <Eartaker> yeah
[08:53:09] <Loetmichel> parts for model planes
[08:53:11] <Eartaker> nice
[08:53:22] <Eartaker> I fly heli;s
[08:53:24] <Eartaker> heli's
[08:53:42] <Eartaker> u in the US?
[08:53:43] <Loetmichel> the company has sold hinges, motor mounts, helicopter parts and illuminating for model planes/helocopters
[08:53:48] <Loetmichel> german
[08:53:50] <Eartaker> ahh
[08:54:21] <Eartaker> I need to find someone close who also does CNC
[08:54:23] <Eartaker> ...
[08:54:43] <Turtl3boi> Eartaker I really want to make a nice rock crawler RC truck
[08:55:07] <Eartaker> Turtl3boi, I never got into rock crawling but I know there is a huge market for it
[08:55:07] <vitaeear> hi EMCusers. !!i , i want to modifiy hal_manualtoolchange , to autoclose his window when "change" pin go to 0. i dont know python , i have made somes tries without success . any idea?
[08:55:56] <Turtl3boi> eartaker do you live near southern cali?
[08:56:01] <Eartaker> Turtl3boi, but of thats the scale of parts you want to make then a 45 size machine would work great
[08:56:15] <Eartaker> Turtl3boi, nope im in WA
[08:56:17] <Turtl3boi> yeah i really don't need that big of a rig i'm thinking
[08:56:22] <Turtl3boi> oh ok coo
[08:56:42] <Eartaker> Turtl3boi, if the 45 is to big look at the g0704
[08:56:58] <Eartaker> http://www.grizzly.com/products/G0704
[08:57:19] <Eartaker> there are CNC kits for this machine
[08:58:08] <Loetmichel> Eartaker: wouldn help you if i would live in the us. the big machine is gone. as boss sold the company i had no intention of moving from Offenbach to berlin. so i quit.
[08:58:21] <Loetmichel> and my own machine is very small
[08:58:42] <Eartaker> Loetmichel, I just wondered
[08:58:43] <Loetmichel> http://www.cyrom.org/palbum/main.php?g2_itemId=12304
[08:58:51] <Turtl3boi> Is Berlin a bad place to live?
[08:59:09] <Loetmichel> Turtl3boi: no, but its about 600km from my home
[08:59:18] <Eartaker> damn
[08:59:25] <Turtl3boi> offenback is near the river main
[08:59:27] <Loetmichel> and my wife has a job HERE
[08:59:37] <Turtl3boi> oh wait is it near frankfurt
[08:59:40] <Loetmichel> it is
[09:00:19] <Loetmichel> ... and as my WIFE is the one here who brings the big money in....
[09:00:21] <Loetmichel> ;-)
[09:00:26] <Turtl3boi> hahaha
[09:00:42] <Turtl3boi> you have one of those flexible keyboards
[09:02:10] <Turtl3boi> so Loetmichel where do you live now
[09:02:17] <Turtl3boi> i mean where do you *work* now
[09:02:20] <Loetmichel> yeah, great if hot swarf get everywhre... bat for typing ;-)
[09:02:27] <Turtl3boi> are you the machinist at a corporation now
[09:02:54] <Turtl3boi> btw do you guys realize I am Quack?
[09:02:57] <Loetmichel> i live still in Offenbach am main near frankfurt and work now in a company which makes computers for the military as a production manager
[09:03:23] <Turtl3boi> computers?
[09:03:29] <Turtl3boi> so you're an electronics guy now
[09:03:29] <Loetmichel> PCs
[09:03:38] <Loetmichel> i was since ever
[09:03:41] <Turtl3boi> you basically build the case and cooling solution
[09:03:53] <Turtl3boi> or do PC board layout?
[09:03:55] <Loetmichel> but a electronics guy who knows how to build a CNC
[09:04:02] <Turtl3boi> oh so you're like me more
[09:04:07] <Loetmichel> Turtl3boi: both
[09:04:08] <Turtl3boi> i'm electronics as well
[09:04:19] <Turtl3boi> interesting
[09:04:30] <Turtl3boi> lemme know if you ever visit the US for a tradeshow or something
[09:04:31] <Loetmichel> not the cooling, but the EMI-shielding
[09:04:50] <Loetmichel> we make Tempest-shielded /rugged computers
[09:05:00] <Turtl3boi> fanless computers?

[09:05:24] <Loetmichel> one ore two of our models are fanless, too
[09:05:36] <Loetmichel> but more emphasis on tempest shielding
[09:06:09] <Loetmichel> http://www.cordsen.com/index.php/tempest/tempest-level-a/workstation/16-tempest/tempest-level-a/workstation-a/105
[09:06:25] <Eartaker> Turtl3boi, no i didnt know u were quack lol
[09:06:26] <Loetmichel> our latest development, nearly complete my design
[09:06:34] <Turtl3boi> ROFL
[09:06:52] <Turtl3boi> but you did seem to remember the conversation we had about your ZX45 and recommending me the PM45
[09:07:17] <Eartaker> yeah I remember conversations but not so much who with lol
[09:08:25] <Turtl3boi> is the tempest some sort of RF shielding mesh?
[09:08:26] <Eartaker> there was another guy on here asking about the 45 though
[09:08:34] <Turtl3boi> hahaha ok i see
[09:08:44] <Turtl3boi> I wonder if Loetmichel realized I was Quack
[09:08:51] <Turtl3boi> especially after I said Dr. B
[09:09:31] <Loetmichel> Turtl3boi: i dont remember any conversation with quack
[09:09:40] <Turtl3boi> hahahahahah wtf
[09:09:41] <Loetmichel> so no, i didnt realize
[09:09:50] <Turtl3boi> i guess you don't care to remember anyone in IRC
[09:09:55] <Loetmichel> _ getting older
[09:09:57] <Turtl3boi> you just like socializing
[09:10:11] <Turtl3boi> you're not old i'm old
[09:10:14] <Eartaker> lol
[09:10:16] <Loetmichel> that is a far stretch in guessing
[09:10:20] <Turtl3boi> i'm 52
[09:10:30] <Turtl3boi> but i act like i'm 30
[09:10:32] <Eartaker> im 25....
[09:10:33] <Turtl3boi> err maybe 25
[09:10:41] <Turtl3boi> damn........
[09:10:45] <Turtl3boi> young little bugger
[09:10:47] <Eartaker> lol
[09:10:58] <Eartaker> one who needs another beer.... brb
[09:11:00] <Loetmichel> no, i just have so much conversation partners that i sometinmes have to look in the scrollback
[09:11:02] <Loetmichel> ;-)
[09:11:05] <Turtl3boi> geeeeeez
[09:11:30] <Loetmichel> Turtl3boi: so you have about 10 years lead to me.
[09:11:33] <Eartaker> =]
[09:11:45] <Turtl3boi> if you want I will learn Deutsch Sprache that way you will remember me better
[09:12:55] <Loetmichel> HRHR
[09:12:58] <Eartaker> mein quack...
[09:13:16] <Loetmichel> no, i think my english is good enough to talk here
[09:13:24] <Eartaker> what?
[09:13:25] <Loetmichel> so no need for you to learn german
[09:13:27] <Eartaker> i dont understand u
[09:14:00] <Eartaker> ^ guy thinks he knows English...
[09:14:06] <Eartaker> lol j/k
[09:14:16] <Loetmichel> and as i said the last time: i am NO doctor
[09:14:43] <Turtl3boi> k
[09:14:46] <Loetmichel> Eartaker: seriously better than YOUR german i presume ;-)
[09:14:49] <Eartaker> I need a 400w high pressure sodum bulb
[09:14:57] <Turtl3boi> actually i do speak quite a bit of german
[09:15:00] <Eartaker> Loetmichel, much better
[09:15:08] <Turtl3boi> you have to remember there are lot of german immigrants in the US
[09:15:19] <Turtl3boi> and a lot of them spoke german not too long ago
[09:15:33] <Loetmichel> Turtl3boi: i know.
[09:15:41] <Eartaker> Turtl3boi, in that theory we should all speak Spanish...
[09:15:42] <Turtl3boi> a lot of the pastries and desserts my grandmother makes have german names so i had to learn
[09:15:45] <Eartaker> here in the US
[09:15:57] <Turtl3boi> i know some spanish too actually, after living so close to the border
[09:15:57] <Loetmichel> Still i think my english good enough to talk here
[09:16:16] <Turtl3boi> never said your english is bad, just thought you would remember me better if i spoke german
[09:16:21] <Turtl3boi> ;)
[09:16:40] <Eartaker> Loetmichel, if you wouldnt have said you were in Germany I would have though US from your english
[09:16:44] <Eartaker> thought
[09:16:47] <Loetmichel> hrhr, dont think so, i have some "not german" friends i talk a lot with
[09:17:10] <Loetmichel> its just that i have so much conversation partners that sometimes one gets lost in memory ;-)
[09:17:54] <Connor> Loetmichel: So, when you talk/type english.. do you think in german then translate into english ?
[09:18:27] <Eartaker> Connor, I have always thought the same about people
[09:18:51] <Eartaker> Loetmichel, do you?
[09:18:52] <Loetmichel> Eartaker: i had always much talk with english/american service ppl, so that will help to stack up the language a bit ;-)
[09:19:05] <Loetmichel> Connor: no, i think in english
[09:19:07] <Eartaker> Loetmichel, ahhh
[09:19:12] -!- cncbasher [cncbasher!~quassel@cpc15-hart9-2-0-cust101.11-3.cable.virginmedia.com] has joined #emc
[09:19:17] <Loetmichel> like i think in german if i talk german
[09:20:06] <Connor> that's cool.. How old when you started learning english ?
[09:20:18] <Loetmichel> schoool, about 10 years
[09:20:27] <Turtl3boi> holy crap
[09:20:31] <Turtl3boi> that's quite a young age
[09:21:06] <Connor> studies show that if you learn languages before the age of 6, they're stored in different part of the brain than if you learn them after..
[09:21:08] <Loetmichel> but i've read english manuals since i was 6 and have learned the letters ;-)
[09:21:52] <Connor> time for bed. later.
[09:22:05] <Loetmichel> 'cause my dad was production manager in an(other) computer company as well, and brought home some of them
[09:22:50] <Turtl3boi> do you realize how many part-german people i know
[09:23:03] <Turtl3boi> there are so many part german people in mexico too
[09:23:04] <Loetmichel> so i learned quickbasic just before learning the german written language ;-)
[09:23:33] <Turtl3boi> one time my teacher asked the class to raise their hand if you are part irish or part german or part italian etc....
[09:23:40] <Turtl3boi> like 80% of the class said they were part german
[09:23:47] <Loetmichel> hrhr
[09:24:03] <Turtl3boi> so many mexicans i know are actually 1/4 or 1/2 german it's hilarious
[09:24:09] <Loetmichel> that could be misleading.
[09:24:26] <Turtl3boi> could be
[09:25:16] <Loetmichel> my wife says she has many american/australian colleagues which say "i am part german" and if asked the cant speak ONE word german because the imigrants were 3 generations ago.
[09:25:47] <Loetmichel> (she works for SAP in a worldwide management-team)
[09:26:26] <Turtl3boi> yeah but there are some families in mexico which still do polka music
[09:26:38] <Turtl3boi> of course lots of people don't study german anymore haha
[09:26:49] <Turtl3boi> not a super easy language at all, probably one of the hardest actually
[09:27:19] <Turtl3boi> that's it Eartaker, i think the ZX45 is the best value
[09:27:23] <Loetmichel> strange thing: the american colleagues put her in the irish corner for her "dialect", the english ones put her to australia, and the australian ones have no idea ;.)
[09:27:31] <Turtl3boi> i hope i can find one used though instead of brand new from bolton
[09:27:37] <Eartaker> Turtl3boi, DO IT
[09:27:44] <Turtl3boi> lol irish corner? wtf
[09:27:46] <Eartaker> or call PM
[09:27:58] <Turtl3boi> well the PM is a bit weaker right
[09:28:12] <Eartaker> as in the motor?
[09:28:45] <Eartaker> 1.5hp
[09:29:00] <Eartaker> but even with t 2hp on the bolton I replaced it
[09:29:03] <Eartaker> with a 3 phase
[09:29:47] <Eartaker> there are 2 build threads with the bolton version you can follow if you want
[09:29:49] <Eartaker> well 3
[09:29:53] <Eartaker> on cnczone
[09:30:35] <Turtl3boi> which one has the single phase option
[09:30:44] <Turtl3boi> i don't want to require a 3 phase converter
[09:30:51] <Eartaker> both
[09:31:00] <Turtl3boi> do you personally have the single phase option?
[09:31:06] <Turtl3boi> do you run it off the 240V outlet?
[09:31:25] <Eartaker> I personaly HAD the single phase one from bolton...
[09:31:26] <Loetmichel> hmm, i should do something useful and clean um my workshop now... ;-)
[09:31:28] <Eartaker> 120v
[09:31:56] <Eartaker> I replaced the motor with a 2hp 3 phse so I could control the spindle via CNC
[09:32:25] <Turtl3boi> why does that require 3 phase?
[09:32:32] <Eartaker> now I run it with 220single phase and it gets converted to 208 3 phase
[09:32:36] <Turtl3boi> why couldn't YOU control the spindle speed with 120v
[09:32:44] <Eartaker> you cant control speed
[09:33:01] <Turtl3boi> Loetmichel let me know if you have plans to visit US so i can talk to you about Haas
[09:33:16] <Turtl3boi> so 3 phase allows speed control?
[09:33:29] <Eartaker> you need a 3 phase for variable speed control and to do that you need a variable frequency drive
[09:34:12] <Eartaker> you dont change the speed of the motor by changing voltage but by changing the freq
[09:34:20] <Loetmichel> will not happen anytime near 'cause i hate the airport security that much
[09:35:04] <Turtl3boi> of course, i wish i could be strip searched by a hot airline officiator
[09:35:14] <Turtl3boi> but that won't happen since i look like a fat computer nerd
[09:35:23] <Eartaker> lol
[09:35:31] <Turtl3boi> yeah actually i hate flying man
[09:35:43] <Loetmichel> a company which grants itself the rght to confiscate my laptop just for industrial espionage will NOT see anything of me soon.
[09:35:48] <Turtl3boi> i don't even travel because for one it takes a lot of money and for two i tend to get sick
[09:36:10] <Loetmichel> i dont geht sick
[09:36:26] <Turtl3boi> because you have a smokestack which kills bacteria
[09:36:28] <Loetmichel> i was at the navy for my military service.
[09:36:47] <Turtl3boi> you smoke a lot. smoking kills bacteria and fungus
[09:36:55] <Loetmichel> hrhr
[09:37:08] <Turtl3boi> do you ever catch a flu virus or cold?
[09:37:32] <Loetmichel> i just ignore small inconveniences like spanish flu ;-)
[09:37:35] <Eartaker> I have never had the flu.... I have never smoked... I get a cold maybe once a year...
[09:38:22] <Eartaker> ok im out... ttyl
[09:38:37] <Turtl3boi> later Eartake
[09:38:46] <Loetmichel> and you're right, i AM smoking like a coal plant ;-)
[09:38:46] <Turtl3boi> hey i let you take my ear for a while there
[09:39:12] <Loetmichel> cul8ter, Eartaker
[09:39:21] <Turtl3boi> hahaha man i wish you would quit the smoking
[09:39:28] <Loetmichel> why?
[09:40:22] <Turtl3boi> oh you know, it's not good for the lungs
[09:40:28] <Turtl3boi> does your wife smoke too?
[09:41:10] <Loetmichel> so what. i work with carbon fibre, i do any kind of bad for the healt work. if i was destined to die from it i would be dead already.
[09:41:13] <Loetmichel> no
[09:41:20] <Loetmichel> health
[09:41:31] <Loetmichel> my wife doesnt smoke
[09:42:13] <Turtl3boi> reduce the smoking a bit slowly day by day
[09:42:33] <Turtl3boi> do a lot of ppl still smoke in frankfurt?
[09:45:00] <Loetmichel> hmmm
[09:45:17] <Loetmichel> dont know. in my company its about 50:50
[09:45:26] <Turtl3boi> wow ........
[09:45:28] <Loetmichel> but that MAY be not representative
[09:45:29] <Turtl3boi> that's a lot
[09:45:49] <Turtl3boi> it's becoming less and less "cool" to smoke in the US
[09:45:56] <Turtl3boi> although I still see a lot of people smoking

[11:05:23] <archivist> something like that :)
[11:07:20] <mrsun> archivist, well i think ill find the 0.05 acceptable realy, just should scrape the underside of the table as that part has just been raw machined from factory
[11:07:32] <mrsun> big grooves in it where the dovetail cutter has gone :/

[11:12:58] <awallin> straight to 0.05 doesn't mean much if you don't tell us the unit and over what distance you are measuring

[11:16:31] <Loetmichel> hmmm, little one...
[11:16:31] <mrsun> but scraping down 0.05mm i have to hog some metal =)
[11:17:15] <archivist> check your measuring too
[11:17:16] <Loetmichel> 0,05 mm would be GREAT if correct.
[11:17:31] <Loetmichel> but i think you should measure again with some load on it
[11:17:44] <archivist> .05 is 2 thou inches, not that good
[11:17:45] <Loetmichel> like a big aluminium block clamped down
[11:17:49] <mrsun> Loetmichel, measuring now on a plane surface
[11:18:28] <archivist> what grade plane though :)
[11:18:33] <Loetmichel> if its the one with the wide table (400 in x) you will notice that the table can war more tan 2mm depending on the force the clamps generate
[11:19:13] <Loetmichel> [12:17:18] <Loetmichel> 0,05 mm would be GREAT if correct. <- it is. for a x1 or clone ;-)
[11:19:31] <mrsun> archivist, hehe, said grade 1 but in the measurment paper i got with it the values were under the threshold for grade 0

[11:20:41] <mrsun> or waity
[11:20:47] <mrsun> long Y and short X maybe it is :P
[11:21:01] <mrsun> in out is longer then usual, but X is original i think :P
[11:22:39] <Loetmichel> archivist: xou can buy the x1 and its clones over here at every hardware store
[11:23:51] <Loetmichel> and depending on the label on int (and the quality check) it is a moderate to REALLY bad mill. i even have seen one where the chines have forgotten do mill the t-slots in the table ;-)
[11:24:16] <mrsun> Loetmichel, i hope if its quite good for a X1 that its my doing as ive been scraping the ways of it to make it straight, hell took me a week to make the Y slides straight :P
[11:24:17] <Loetmichel> (slots were cast in, but no "t"-milling)
[11:24:33] <mrsun> one of them was quite straight other one was dipping like hell =)
[11:24:58] <Loetmichel> mrsun: ok, if you reworking it: good job ;-)
[11:25:19] <mrsun> Loetmichel, had as the table bound up so i had to have the gibs lose for it to work :P

[12:36:49] <Valen> are you milling or drilling IG-garage
[12:36:52] <Valen> ahh drilling
[12:37:03] <Valen> there is a special sharpening you need to do to drill fiberglass
[12:37:09] <Valen> i cant rember what it is though lol
[12:37:12] <IG-garage> Valen: we were first drilling then turning it
[12:37:26] <Valen> my dad used to to fiber glassing for a living and used to show people
[12:37:56] <IG-garage> Valen: I know, but the cutting edge itself becomes round too soon comparing to the regular steel
[12:38:01] <Loetmichel> IG-garage: i hope you had evac for the dust?
[12:38:07] <IG-garage> Loetmichel: yes
[12:38:42] <Loetmichel> Valen: fibre glass/ carbon only with tungsten carbide drills
[12:38:54] <IG-garage> I opened the window a little (in winter, -10 celsius degree), and turned on the dust mask
[12:38:59] <Loetmichel> HSS is gone in seconds
[12:39:13] <IG-garage> co-workers were itching, but i'm a tough guy
[12:39:22] <Loetmichel> bah
[12:39:31] <IG-garage> Loetmichel: exactly a HSS
[12:39:41] <Loetmichel> IG-garage: fibreglass dust is cancerinducing, you know that?
[12:39:59] <IG-garage> Loetmichel: i did not breath with it
[12:40:27] <IG-garage> used dust mask and fresh air for not feeling the smell.
[12:41:02] <Loetmichel> and now every surface in your workshop is covered with cancer inducing dust
[12:41:06] <Loetmichel> great.
[12:41:57] <IG-garage> yeah
[12:42:13] <Valen> IG-garage: i know what your talking about, but if you sharpen the drill with a different profile it wont become blunt anywhere near as quick
[12:42:28] <IG-garage> Valen: why not?
[12:42:51] <Valen> like you use different rake and such for plastic and steel, using a bit with a cutting profile appropriate for steel in glass wont work very well
[12:43:06] <IG-garage> I sharpened drill bit about 80-90 degrees
[12:43:34] <Valen> i just don't know off the top of my head what the difference was
[12:44:07] <IG-garage> and close to the end of the work, i was starting to sharping it closer to regular 120 degrees to prepare bits for steel
[12:44:24] <Valen> but he would go to a place and they would be bitching about fiberglass because it would dull their drills he would show them how to sharpen them for the glass and whilst still somewhat agressive it wasn't an issue anymore
[12:44:34] <IG-garage> anyway, we needed to make out the order.
[12:46:41] <IG-garage> he could sharpen it at unusual way, e.g. make something like stairs out of the back surface of the the drilling bit.
[12:47:54] <IG-garage> and feedrate should be quite aggressive but moderate for the drill to not push out the last layer of the laminate. That's all I know for a while.
[12:53:14] <IG-garage> Loetmichel: you can read that article in English by now

[16:49:49] <danimal_laptop> whole screen
[16:50:15] <Jymmm> danimal_laptop: are there drivers for it?
[16:50:17] <danimal_laptop> Jymmm: i thought so but im not able to get online yet with this pc
[16:50:33] <Jymmm> danimal_laptop: Ah, might be a config thing to correct that
[16:50:47] <danimal_laptop> not sure how to get the wireless working so i need to buy a new network cable
[16:50:57] <A2Sheds> it needs to be recalibrated
[16:50:59] <sliptonic> Has the site been hacked again? http://img6.imagebanana.com/img/0kjlkq8t/LinuxCNC.orgHomeChromium_016.png
[16:51:06] <danimal_laptop> Jymmm: yea, thats what im guessing
[16:52:58] <A2Sheds> did you try changing your dns? try 8.8.8.8 google open dns
[16:53:43] <danimal_laptop> A2Sheds: didnt see anything in the manual for calibrating it on the monitor
[16:54:43] <A2Sheds> what type of touch screen? resistive?
[16:54:45] <SWPLinux> that's a rendering problem, possibly due to something like noscript (or other settings)
[16:54:54] <danimal_laptop> i dunno, it's an elo

[16:56:31] <A2Sheds> somebody must have reported it as a phishing site to opendns

[17:00:55] <A2Sheds> ELO 5 wire
[17:01:43] <A2Sheds> http://www.elotouch.com/Support/Downloads/dnld.asp
[17:02:56] <A2Sheds> ELO has prebuild drivers for unbuntu but they are probably not going to work since EMC has a custom kernel
[17:03:20] <A2Sheds> you'll have to get the source and compile against the EMC ubuntu kernel

[17:05:14] <A2Sheds> or try the generic Linux driver
[17:05:21] <danimal_laptop> i fixed it
[17:05:34] <danimal_laptop> i found someting on google telling how to invert it
[17:06:09] <A2Sheds> swap the sense wires? :)
[17:06:37] <A2Sheds> I imagine you'll still want to calibrate the panel

[18:50:32] <Tom_itx> what gives?
[18:50:37] <danimal_laptop> works pretty bitchin
[18:50:46] <danimal_laptop> huh?
[18:50:53] <Tom_itx> what did you do?
[18:51:00] <danimal_laptop> got my touch screen working
[18:51:06] <danimal_laptop> and calibrated
[18:51:13] <Tom_itx> i know but how did you flip it over?
[18:51:39] <danimal_laptop> just entered some crap in terminal that i found in a google search
[18:51:50] <danimal_laptop> http://ubuntuforums.org/showthread.php?t=1460948
[18:55:36] <danimal_laptop> so these elo monitors work pretty good with ubuntu, fyi
[18:55:59] <Tom_itx> good to know
[18:56:07] <danimal_laptop> i got the kiosk model so i can mount it behind a pannel
[18:57:18] <Tom_itx> i have an ldvs i wanted to use but it got cracked in shipping

[18:58:03] <Tom_itx> can't find one to replace it
[18:58:25] <Tom_itx> not surplus anyway and i'm not gonna get a new one
[18:58:55] <Tom_itx> i had a chance to get several 17" touch pannels for like $65
[18:59:03] <danimal_laptop> nice
[18:59:11] <Tom_itx> had no room for them at the time or use

[19:15:43] <danimal_laptop> so when i rebooted the computer, it reverted back to the old calibration settings
[19:16:06] <danimal_laptop> any way to keep it from doing that so i dont have to reset it every time i reboot?
[19:17:44] <IchGucksLive> jepler: ?
[19:18:01] <alex4nder> danimal_laptop: what calibration tool are you using?
[19:18:18] <IchGucksLive> someone Know about axis.py
[19:18:26] <IchGucksLive> widgets.menu_view.configure((".menu.view",'_ "Show XYUV Plane"'),state=DISABLED)
[19:19:02] <danimal_laptop> i just change the settings in terminal
[19:19:12] <danimal_laptop> i dont know if there's a tool involved
[19:19:34] <FinboySlick> danimal_laptop: Can you pastebin what you do in terminal?
[19:19:46] <alex4nder> danimal_laptop: just add the configuration to your xsession or whatever.
[19:20:10] <danimal_laptop> xinput set-int-prop "Elo TouchSystems Inc. Elo TouchSystems IntelliTouch 2500U" "Evdev Axis Calibration" 32 990 3686 936 3341
[19:20:16] <danimal_laptop> something like that
[19:21:34] <alex4nder> danimal_laptop: I don't have my Ubuntu install in front of me, but couldn't you just add a system-wide script in /etc/X11/Xsession.d to do that configuration?
[19:21:58] <danimal_laptop> i dont know, im reading on that now, thanks
[19:22:03] <danimal_laptop> im a linux newb
[19:22:15] <FinboySlick> danimal_laptop: You can apparently do that with an InputClass section in xorg.conf
[19:22:24] <alex4nder> or that
[19:22:34] <danimal_laptop> cool thanks
[19:22:52] <syyl> uhm
[19:23:04] <syyl> do i need a index signal for rigid tapping?
[19:23:04] <syyl> Oo
[19:23:08] <FinboySlick> the inputclass method is probably the 'proper' way to do things, but I'm not entirely familiar with it with respect to your device.
[19:23:21] <syyl> or is a/b signal enough
[19:23:37] <alex4nder> FinboySlick: it's proper because the X server will use it regardless of startx/gdm/xdm/whatever.
[19:23:49] <alex4nder> but it's annoying because it's X configuration.
[19:24:55] <danimal_laptop> isnt xorg.conf for display properties?
[19:25:40] <alex4nder> yah, but your X server acts as the central point for all input/graphics.
[19:27:50] <FinboySlick> Things moved quite a bit with respect to that. For a while, they used a hardware abstraction layer for xorg device configuration, now they moved away from it in favor of something else. In that sense, I'm not 100% sure xorg.conf is actually the proper proper place for this. It might be udev now for all I know, so that settings are applied once the device is detected.
[19:27:51] <alex4nder> for your home/limit switches, do people tend to run them in the same cable as the stepper motor coils, or external?
[19:33:31] <awallin> if you have small/medium steppers then there will probably not be much noise/trouble with running switch-wires close to the motor wires
[19:34:07] <alex4nder> yah, I've got little 166 oz/in steppers
[19:35:00] <IchGucksLive> awallin: Progress is flowing
[19:35:21] <awallin> IchGucksLive: you are modding AXIS some more?
[19:35:44] <IchGucksLive> alex4nder: http://www.mechmo.de/5-achsen.mp4
[19:35:49] <syyl> i think i messed my spindle encoder up...

[19:36:07] <IchGucksLive> awallin: till it works my way
[19:36:17] <syyl> i get more than one index signal per revolution of the main spindle..
[19:36:29] <IchGucksLive> awallin: now g17.1 is implemented
[19:36:45] <awallin> syyl: 1:1 coupling somewhere at the top of the spindle-shaft is better if possible?
[19:36:50] <alex4nder> IchGucksLive: what're you using to the steppers?
[19:37:06] <syyl> i know, but there was no space for that...

[23:34:39] <alex4nder> anyone have an opinion on half or full winding wiring with a unipolar (6 wire) stepper but with a bipolar (4 wire) drive?
[23:35:12] <alex4nder> my steppers are 166 oz/in, and my machine is a taig with 20 TPI screws
[23:36:03] <alex4nder> I think I'm just going to do half winding.
[23:37:59] -!- crib has quit [Ping timeout: 245 seconds]
[23:38:37] <ssi> can you do that? I thought you had to have a unipolar drive for unipolar motors
[23:38:41] <ssi> but it's been awhile since I looked at it :/
[23:38:54] <alex4nder> I'd just be leaving off half the coil on each phase.
[23:39:07] <alex4nder> so lower inductance, but less windings
[23:39:22] <alex4nder> so more power into the stepper, and better high-speed
[23:39:49] <ssi> what's the downside
[23:39:57] <ssi> less max current capacity?
[23:39:58] <alex4nder> lower low-speed torque
[23:40:19] <alex4nder> but I've got 20 TPI screws, so is that enough mechanical advantage to make that not matter?
[23:40:31] <alex4nder> like, do I want more speed?
[23:40:37] <ssi> what kind of machine is it?
[23:40:40] <alex4nder> a taig
[23:40:47] <ssi> probably be fine
[23:40:50] -!- uwe_ [uwe_!~uwe_@dslb-188-105-018-016.pools.arcor-ip.net] has joined #emc
[23:40:52] <ssi> the torque really just gains you acceleration
[23:41:22] <ssi> if it was a plasma machine that needs to be able to cut sharp corners without slowing down, you need a pile of accel
[23:41:25] <ssi> on a mill you really don't
[23:41:34] <alex4nder> hmm, ok.
[23:41:37] <alex4nder> I'll try it out half-winding.
[23:41:54] <alex4nder> I've got enough power supply to run the steppers at max current, so that's fine.
[23:42:10] <ssi> is your supply voltage more matched to the half-winding inductance?
