[00:00:07] <aa-danimal-shop> did they give any info like teeth # or pitch?
[00:00:10] <alex_joni> clytle374: used a couple: Lenze, Stoeber, ..
[00:00:20] <aa-danimal-shop> i didnt see anything
[00:00:24] <alex_joni> I suspect the names aren't familiar for you.. mostly german brands
[00:00:39] <JT-Hardinge> no but I could count the new one for the Z when it comes in... it is the same as the X
[00:00:50] <aa-danimal-shop> i figured they wouldnt do that because then noone would buy their $30 belts when you can buy the same one for $4 lol
[00:00:51] <JT-Hardinge> it's 1" wide
[00:00:54] <clytle374> I've seen them, but can't place them.. Where are you at was going to be the next question.
[00:01:03] <aa-danimal-shop> ah ok, mine are 3/4" wide
[00:01:08] <alex_joni> eastern europe
[00:01:44] <alex_joni> http://www.lenze.com/lenze.com_en_active/020_Products/020_Servo_drives/010_Servo_Umrichter/020_Servo_System_ECS/Produkt_ECS_Servosytem.com.jsp?cid=0b0164e08009090b
[00:02:09] <clytle374> I think I saw them on a highspeed mold detailing machine.
[00:03:17] <alex_joni> not cheap
[00:04:04] <clytle374> Quality usually isn't.
[00:05:22] <clytle374> Us Americans aren't generally smart enough to buy things that last anymore.
[00:06:01] <alex_joni> I'm sure my customers would buy cheaper stuff given the chance
[00:06:12] <alex_joni> luckily they don't have to chose
[00:06:37] <alex_joni> anyways.. off to bed for me (2am)
[00:06:47] <JT-Hardinge> goodnight Alex
[00:07:38] <clytle374> night
[00:11:10] <owhite> hello people. If I wanted to perform a G4 dwell. Is it accurate down to the milliseconds? Could I do: "G4 P0.0002" ?
[00:12:44] <JT-Hardinge> I doubt it
[00:13:55] <aa-danimal-shop> i'm pretty excited, my new process and fixtures for making chainrings worked awesome
[00:14:03] <aa-danimal-shop> :)
[00:14:28] <JT-Hardinge> cool, got any photos?
[00:14:36] <aa-danimal-shop> it's nice having the lathe, it saves me a ton of time
[00:14:46] <JT-Hardinge> which one?
[00:14:52] <aa-danimal-shop> the HNC
[00:14:58] <JT-Hardinge> :)
[00:15:02] <aa-danimal-shop> no pics yet
[00:15:11] <JT-Hardinge> mine eats up a ton of my time
[00:15:33] <aa-danimal-shop> the main part of the lathe fixture is just a 7.5" face plate i made
[00:15:57] <JT-Hardinge> you have an A2-5 mount?
[00:16:03] <JT-Hardinge> spindle nose
[00:16:31] <aa-danimal-shop> there's arbors and caps that hold the chainring to the faceplate, locating on a close tollerance 1" hole in the center
[00:16:41] <aa-danimal-shop> no, i have the hardinge 4" taper
[00:17:00] <aa-danimal-shop> 4 degree taper*
[00:17:15] <aa-danimal-shop> like the old toolroom lathes and whatnot
[00:17:40] <JT-Hardinge> short nose mount?
[00:17:53] <aa-danimal-shop> yea, it's pretty short
[00:18:10] <JT-Hardinge> I bet it is an A2-5 like mine
[00:18:22] <aa-danimal-shop> got about a 4 degree taper, and a t shaped groove in it which a pin slides in
[00:18:24] <aa-danimal-shop> no
[00:18:40] <JT-Hardinge> no, not like mine then
[00:18:46] <aa-danimal-shop> this is a hardinge proprietary design
[00:18:56] <aa-danimal-shop> usually only seen on manual lathes
[00:19:01] <aa-danimal-shop> i have an odd one
[00:19:13] <aa-danimal-shop> the chuckers usually have a threaded spindle nose
[00:19:51] <JT-Hardinge> I guess you could get anything you want when you buy it new :)
[00:20:02] <aa-danimal-shop> lol true
[00:20:15] <aa-danimal-shop> granted i didnt buy it new, so i got stuck with this
[00:20:33] <JT-Hardinge> yeppers
[00:23:57] <owhite> would anyone have a suggestion for how I could execute a G code for a very short duration of time, something in the millisecond range?
[00:25:13] <JT-Hardinge> owhite: what are you trying to do?
[00:26:25] <owhite> well. I run a laser, I start the laser using gcode M64 P2 and shut it off with M65 P2.
[00:27:06] <owhite> and I'd like to do....M64 P2; G4 P.002; M65 P2;
[00:27:21] <owhite> the purpose is that I need a pulse of the laser in order to do some testing.
[00:27:34] <JT-Hardinge> what part of the world are you located?
[00:27:45] <owhite> baltimore md.
[00:28:18] <JT-Hardinge> look for migte in the AM is from Europe and does lasers
[00:28:27] <JT-Hardinge> I might have spelled his nick wrong
[00:28:35] <owhite> ok.
[00:28:37] <JT-Hardinge> mitge maybe
[00:29:11] <clytle374> Probably have to build or interface a pulse generator
[00:29:27] <JT-Hardinge> one second I'll jump in the wayback machine and get the correct nick
[00:29:37] <owhite> yeah I was hoping to have a quick solution.
[00:29:59] <clytle374> How accurate do you need to be?
[00:30:02] <owhite> this test I got to run is sort of one time thing.
[00:30:05] <owhite> not accurate.
[00:31:01] <JT-Hardinge> micges_work and micges
[00:31:17] <owhite> thanks JT-hardinge
[00:31:45] <JT-Hardinge> dang did I guess wrong on micges nick
[00:32:33] <JT-Hardinge> your just wanting to pulse the laser for a short duration
[00:32:49] <owhite> JT: yes.
[00:32:59] <owhite> on ...20 millisec....off.
[00:33:38] <JT-Hardinge> how about a m64 g0 x0.00001 then m65 on next line
[00:34:03] <JT-Hardinge> or 62/63
[00:34:10] <owhite> oh, hm.
[00:35:05] <clytle374> Can stepgen run that tight?
[00:35:05] <JT-Hardinge> * JT-Hardinge goes back to ladder logic
[00:35:29] <JT-Hardinge> well maybe one too many zeros
[00:35:59] <JT-Hardinge> worked here
[00:37:03] <JT-Hardinge> I think
[00:40:52] <owhite> thanks people.
[00:42:43] <aa-danimal-shop> yay for G64 P###
[00:47:14] <aa-danimal-shop> woohooo!! the new process gets rid of the pain in the ass burr i had before. this will save me about 5 minutes each part!
[00:49:16] <JT-Hardinge> your having too much fun Dan
[00:51:21] <aa-danimal-shop> JT-Hardinge, it's a big deal to me. these are parts i make day in and day out.
[00:51:46] <aa-danimal-shop> :)
[00:53:03] <pfred1> aa-danimal-shop everytime you say day in day out I want to hear this song: http://www.youtube.com/watch?v=tRnWYALFPCw
[00:54:35] <aa-danimal-shop> lol
[00:55:02] <aa-danimal-shop> good tune
[00:55:28] <pfred1> if Ian wouldn't have killed himself you'd have never heard of U2 and a few other bands
[00:56:33] <aa-danimal-shop> ugh, i dislike U2
[00:56:56] <pfred1> well JD was a LOT better but alas once Ian died it was no more
[00:57:08] <aa-danimal-shop> yea
[00:57:20] <aa-danimal-shop> bono is a douche
[00:57:40] <pfred1> I'm sure fame ruined him sruff can go to ones head
[00:57:44] <pfred1> stuff even
[01:01:59] <JT-Hardinge> aa-danimal-shop: COOL
[01:05:22] <aa-danimal-shop> JT-Hardinge, once i finish my quick change pallet system, i'll snap some pics
[01:38:30] <pfred1> * pfred1 fritters away some time in http://www.cnczone.com/forums/showthread.php?p=747620#post747620
[01:48:47] <pfred1> I'm starting to feel it I think I'm really starting to feel it over here http://img690.imageshack.us/img690/9582/ppbbr4brd.png
[01:49:26] <aa-danimal-shop> dooooo ittttt
[01:49:50] <pfred1> aa-danimal-shop well whenever I design something eventually I just get this overwhelming urge to have it then I make it
[01:50:25] <pfred1> aa-danimal-shop andi have to say it is coming on strong for me now
[01:50:31] <aa-danimal-shop> lol
[01:50:37] <aa-danimal-shop> DOOOO ITTTTTTT!
[01:50:48] <pfred1> this buffer is bad assed!
[01:51:08] <pfred1> I tweaked a few things one cannot start the build too soon
[01:52:11] <DaViruz> 1Kohm @ 33V = 1 amp and 33 watts.
[01:52:14] <DaViruz> what?
[01:52:33] <pfred1> DaViruz what do you think it is?
[01:53:23] <DaViruz> i'll have to read the rest of the thread before i make an ass out of myself
[01:53:29] <pfred1> last i checked 33^2/1000 = 1.089
[01:54:16] <DaViruz> that is the formula for power yes
[01:54:25] <pfred1> DaViruz guy used a bleeder on a cap 1K ohm
[01:54:26] <DaViruz> which gives you 1.089W
[01:54:37] <DaViruz> and 33mA
[01:54:42] <pfred1> DaViruz but it was only a 20 watt resistor
[01:54:57] <DaViruz> which is way overkill since it only puts out 1W
[01:55:01] <pfred1> DaViruz w=exi
[01:55:17] <DaViruz> yes
[01:55:27] <pfred1> whats 1 times 33?
[01:55:37] <DaViruz> current is not 1
[01:55:52] <pfred1> why isn't it?
[01:55:53] <DaViruz> current is voltage/resistance
[01:56:04] <pfred1> DaViruz try squaring the v
[01:56:19] <DaViruz> no, that will not give me current
[01:56:25] <DaViruz> that will give me power
[01:56:35] <DaViruz> power = v*v*i
[01:56:40] <DaViruz> current = v*i
[01:56:43] <Jymmm> 1 *.033
[01:57:08] <pfred1> ack! I used the wrong formula my bad
[01:59:40] <pfred1> DaViruz thanks for catching that I thought the resistor looked beefy but it didn't add up
[01:59:49] <DaViruz> wow, what i just typed is totally wrong too ;)
[01:59:58] <DaViruz> as it turns out
[02:00:18] <DaViruz> i get confused when not using si variables
[02:00:19] <pfred1> DaViruz really what i do is put an LED and dropepr there so I can watch it glow down
[02:00:40] <pfred1> DaViruz and it doesn't take that long to bleed off
[02:00:59] <pfred1> and you don't toss away all sorts of your supplies power doing it either
[02:01:01] <DaViruz> power = V*V/R, current = V/R, is what i intended to say
[02:01:30] <DaViruz> oh well
[02:01:37] <pfred1> DaViruz I mean this guy has a marginal supply so I figured why waste more of what he doesn't have?
[02:01:45] <DaViruz> yeah that's true
[02:02:19] <pfred1> he has 270 oz/in bipolar steppers and it sounds like he's getting 50 IPM on 10 TPI
[02:02:52] <pfred1> now either he bent those leads like pretzens when he built his machine or there is something else going wrong
[02:03:22] <pfred1> and i know when I started messing wiht steppers power supply was an issue
[02:03:42] <pfred1> steppers just don't peform well unless you give them all the power they want
[02:04:07] <aa-danimal-shop> hell even my big stepper machine can do over 120ipm
[02:04:28] <aa-danimal-shop> i can even get 150ipm out of it, but it stalls if i really abuse it
[02:04:39] <pfred1> 270 oz/in bipolars should really move a router
[02:04:47] <aa-danimal-shop> yea
[02:05:25] <pfred1> sounds like the guy ripped a power supply out of an old printer and used it sort of as is
[02:05:26] <aa-danimal-shop> mine are nema 43 1350oz/in, they're slow as hell in comparison
[02:05:38] <aa-danimal-shop> lol i saw that
[02:05:46] <pfred1> and there was some extra circuitry going on
[02:05:52] <pfred1> get rid of it!
[02:06:39] <pfred1> go with the basics unless you know what you're doing and have a damned good reason for doing so too
[02:07:13] <pfred1> trans bridge filter and go
[02:08:05] <aa-danimal-shop> lol
[02:08:18] <aa-danimal-shop> i dont know crap, so i stuck with the PS that was in my machines
[02:08:33] <pfred1> well if something works don't fix it
[02:08:44] <aa-danimal-shop> yea
[02:08:47] <pfred1> but if it don't toss all the extra junk
[02:09:23] <aa-danimal-shop> i tossed 780lbs of antique controller lol
[02:09:29] <pfred1> thats basic problem solving 101 simplify
[02:09:49] <pfred1> break something down into managable components and go from there
[02:10:04] <JT-Hardinge> aa-danimal-shop: OK Dan can't wait to see them
[02:10:22] <pfred1> reduce your variables
[02:10:28] <aa-danimal-shop> JT-Hardinge, i might patent it
[02:10:37] <JT-Hardinge> Cool
[02:11:37] <pfred1> http://www.tinaja.com/patnt01.asp
[02:12:31] <pfred1> my man Don doesn't believe in patents
[02:14:23] <DaViruz> nor web design, apparantly ;)
[02:14:29] <pfred1> this one sounds entertaining: http://www.tinaja.com/glib/patnthor.pdf
[02:14:48] <pfred1> DaViruz hey don't crack on Don he wrote the TTL Cook book!
[02:17:18] <DaViruz> i'm pretty sceptical towards patents myself to tell the truth
[02:19:54] <pfred1> DaViruz it sounds like Don got burned a few times by the practice and has become a lifelong advocate against them
[02:20:22] <pfred1> these days with China I mean why bother?
[02:20:29] <DaViruz> yeah i got that impression as well :)
[02:20:44] <pfred1> you're a national hero over there if you steal something and produce it
[02:21:04] <pfred1> submiting a patent just makes their life easier
[02:28:09] <pfred1> DaViruz html isn't Don's thing too bad the web isn't postscript?
[02:29:14] <DaViruz> well, it's the colors and the cloudy background that got me
[02:29:21] <DaViruz> the overall layout was nice enough
[02:29:41] <pfred1> I've never known his site to change in appearance since the mid 90s
[02:30:10] <DaViruz> yeah it had a mid-ninetys-feel to it :)
[02:30:16] <pfred1> his big thing seems to be magic sinewaves not that i understand what he's talking about with them
[02:30:26] <pfred1> http://www.tinaja.com/magsn01.asp
[02:30:40] <pfred1> but he's very pumped about them whatever they are
[02:39:21] <pfred1> should i ask Don a magic sinewaves question? like can I make a stepper motor driver with them or something?
[02:40:46] <DaViruz> yes but it will only work with magic steppers
[02:41:20] <pfred1> hmm seems Don likes 3 phase stepper motors
[02:44:27] <pfred1> damn Don was into the LMD18245 back in 1996
[02:44:58] <pfred1> make that 1995 http://www.tinaja.com/glib/muse93.pdf
[03:00:27] <dmz_> i need a drive for a dc spindle motor
[03:00:59] <dmz_> 7.5hp
[03:02:13] <pfred1> dmz_ your needs are not immodest
[03:02:39] <pfred1> or rather not modest I should say!
[03:03:01] <aa-danimal-shop> 7.5hp will cut some cheese
[03:03:37] <pfred1> dmz_ steal one out of one of these: http://www.metaefficient.com/wp-content/uploads/tesla-electric-car.jpg
[03:04:40] <pfred1> dmz_ they're all dead now so no one will miss any
[03:05:37] <pfred1> I swear spam gets weirder by the day doesn't it?
[03:06:32] <pfred1> I'm almost tempted to open this one up but I fear its not what I think it is ---> Grow tomatoes as big as grapefruits
[03:06:56] <dmz_> i bought a mill off ebay with fanuc controls and the spindle drive was missing
[03:07:35] <dmz_> it was big, had a whole box about 2ft x 3ft to itself
[03:07:40] <pfred1> dmz_ if you hurry maybe you can find that auction too!
[03:08:29] <pfred1> fleabay the Internet scam artist magnet site
[03:08:38] <dmz_> i dont know the part number plus it connects to ancient 1979 fanuc controls..
[03:08:58] <dmz_> i was hoping to put it on emc
[03:10:34] <pfred1> dmz_ can't just forget about the speed control for now and simply run the motor?
[03:12:01] <dmz_> its a dc permanent magnet motor
[03:12:53] <pfred1> dmz_ I think the operative word is motor as in anything that spins will do
[03:15:11] <dmz_> a battery charger will spin it, barely tho
[03:16:05] <pfred1> how many volts does it operate at?
[03:16:57] <pfred1> seriously why not scrap the motor and put in an AC motor with a VFD like everyone seems to use today?
[03:17:20] <dmz_> not sure, its way up in the air, havent climbed up and looked
[03:17:39] <dmz_> i think the ammeter goes up to 150a
[03:17:54] <dmz_> looked at the nameplate
[03:19:34] <dmz_> that might be cheaper plus im sure i could run it faster, its limited to 3k rpm now
[03:19:56] <dmz_> if it worked it would be anyway
[03:20:24] <aa-danimal-shop> doesnt dc have more torque?
[03:20:38] <pfred1> at low speed I think
[03:20:48] <aa-danimal-shop> yea
[03:20:59] <aa-danimal-shop> i bet a dc motor would be better
[03:21:02] <pfred1> it'd cost you a mint to make a controller for that motor
[03:21:10] <aa-danimal-shop> buy one.
[03:21:34] <aa-danimal-shop> it'd probably be similar to a dc servo drive, right?
[03:21:42] <pfred1> aa-danimal-shop I doubt they give them away to everyone who walks through the door and bats their eyes either!
[03:21:49] <dmz_> i have the hp/rpm curve for a smaller one, it can put out 3hp at 100rpm
[03:21:55] <dmz_> aa: yea
[03:22:14] <pfred1> so the motor is direct drive to the spindle?
[03:22:28] <aa-danimal-shop> just look for a big servo amp... i've seen them for relatively cheap
[03:22:28] <dmz_> no it has 2 gears
[03:23:21] <pfred1> whats 1 HP 750 watts?
[03:23:48] <pfred1> 5625 watts
[03:25:12] <pfred1> at 220V its still 25.5 amps!

[03:26:17] <pfred1> dmz_ at least you have a nice big project case to put your motor driver in sounds like you're going to need it too
[03:26:23] <aa-danimal-shop> they got lots of crap
[03:28:57] <pfred1> dmz_ I think I found your missing motor drive: http://www.hgrindustrialsurplus.com/sub/product_detail.aspx?id=14-117-337&searchtable=1&sortExpression=&SortASC=&pageSize=50&currentPageIndex=0&searchNAP=
[03:31:24] <pfred1> aa-danimal-shop they appear to love money too
[03:33:17] <dmz_> that place is cheap
[03:33:25] <dmz_> cheaper than ebay for sure
[03:33:40] <pfred1> dmz_ I donno checked their ebay page out?
[03:33:51] <pfred1> http://stores.ebay.com/hgrauctions__W0QQ_pgnZ4Q3frefidQ3dstoreQQ_sacatZhgrauctionsQ5fQ5fW0Q51Q51Q5farmrsQ5A1QQ_sidZ831677214QQ_trksidZp4634Q2ec0Q2em14
[03:33:51] <dmz_> nope
[03:36:00] <pfred1> 1 SET THK SSR25XW3SSE+1170LK LINEAR RAIL ASSEMBLIES,NEW Starting bid:US $3.99
[03:36:51] <pfred1> thats cheap!
[03:36:54] <dmz_> i was just looking at that
[03:37:10] <dmz_> not a set tho
[03:37:22] <dmz_> 2 look the same, the rest oddball
[03:38:48] <pfred1> almost 4 foot
[03:39:14] <Guest827> Trying to get the spindle index pulse working is kicking my butt.
[03:40:12] <Guest827> I can see it working on the breakout board and in HALmeter, but the example g33 program just sits there waiting for an index pulse.
[03:40:56] <dmz_> the mill i have that needs the spindle drive has about 40" x travel 20"y 20"z
[03:42:35] <pfred1> I think the longest i can continiously mill on my machine is 13 1/2"
[03:42:49] <pfred1> in X of course
[03:45:28] <pfred1> getting thse sure would simplify my machine build
[03:51:31] <tom3p> a pair of rails usually has 1 edge/lip for 1 rail to butt up against, the 2nd rail can just be on a flat surface the 1st rail is held straight by the edge, the 2nd will follow 1st..
[03:52:10] <tom3p> and that lip is difficult for hobbyists to machine (40" straight)
[03:55:06] <pfred1> tom3p you're saying there's a lip on one rail?
[03:55:58] <tom3p> theres a lip on the surface where the rails mount. one rail butts up lengthwise along the lip. that makes 1 rail straight
[03:56:15] <pfred1> on the bottom?
[03:56:25] <tom3p> its only 2mm or so high, and many many pusher blocks push the rail up against it
[03:57:11] <tom3p> bottom? its on the machine bed that the rail bolts to
[03:57:43] <pfred1> so there is no lip on the rail?
[03:59:20] <tom3p> correct, see page 12 here http://www.nookindustries.com/pdf/NookProfileRail.pdf
[04:00:18] <tom3p> the lip is often ground, and the inside corner in relieved. tho i disagree with the picture ( i'd only have the lip on 1 rail )
[04:01:42] <tom3p> and the cheap trick for the pusher blocks ( expensive ) is to use a taper headed machine screw and a dowel pin. as the screw bears, the dowel pin inder the tapered head pushed into the rail, up against the lip
[04:02:29] <tom3p> the normal mounting bolts hold the rail down, the tapered head screws & the lip make the long wiggly rail straight
[04:02:50] <tom3p> anything 1" cross section and 40" long is wiggly ;)
[04:04:03] <tom3p> ah, page 17 shows how the lip is used with pushers
[04:04:19] <pfred1> well I could probably make it a little less wiggly than the MDF and roller skate bearings I'm going to use
[04:04:26] <tom3p> yep
[04:05:07] <tom3p> you can just mount it w/o the rail and get a lot of benefit ( sorry lost prespective )
[04:05:10] <pfred1> but I'm not going to buy them anyways maybe a few machines down the road? I am watching the auction though curious to see what they go off for
[04:05:17] <tom3p> w/o the lip
[04:05:38] <pfred1> something tells me they'll go up from the $3.99 opening
[04:05:46] <tom3p> watch to see the final price
[04:05:50] <pfred1> yes
[04:06:26] <tom3p> i just spent a whole day removing the rail, bearings and leadscrews from a machine that was going to scrap. i want going to let that stuff get trashed
[04:06:38] <pfred1> what I'd so is make the table screw down one side and move the table down and screw the rails down as I go
[04:06:39] <tom3p> and i aint gonna sell a whole day for a couple bucks
[04:07:39] <tom3p> nail 1 rail down, check as best you can that it's straight, then loose mount the 2nd rail and make it parallel, nail it down
[04:08:11] <tom3p> you can make parallel by mounting an indicator to a bearing block on rail1 touching rail2
[04:08:27] <pfred1> yeah that'd be a good way to go too
[04:08:41] <Dave911> Does anyone know where there are screenshots of the "Touchy" interface on the web?
[04:08:45] <pfred1> make one straight and truck an indicator down the other one
[04:10:07] <tom3p> making rail1 straight is the trick... mount the indicator from a bearing block ON rail1 TO another bearing block on rail1. move the pair along the length, any deviation means a bend
[04:10:17] <pfred1> well all I need to do now is make my parts list http://img690.imageshack.us/img690/9582/ppbbr4brd.png
[04:12:03] <tom3p> connectors?
[04:12:32] <tom3p> nice pic, what program is that?
[04:12:37] <pfred1> tom3p I snipped a parallel port wire that goes on a PC going to wire it direct
[04:12:51] <pfred1> Eagle with the colored option
[04:13:26] <pfred1> schematic http://img11.imageshack.us/img11/1819/ppbb4sch.png
[04:13:26] <tom3p> ah, a pigtail, and I didnt know eagle made such nice output, thx
[04:14:18] <pfred1> I was going to use the 26 pin double header but I figured why bother?
[04:15:24] <pfred1> just another connector to worry about
[04:16:08] <pfred1> I'm thinking for strain relief I'll slot the perfboard and slide the ribbon cable through it
[04:16:26] <pfred1> maybe hot glue it
[04:16:58] <tom3p> in years of servicing machines, the connections ranks as problem #1. less connections is good. a couple holes and a tie wrap is cheap to do on a pcb
[04:17:24] <pfred1> yeah why put another one on I don't need?
[04:17:43] <pfred1> ribbon already has more than enough wire
[04:18:25] <tom3p> its a toss between being able to isolate a problem ( disconnect ) or make a problem ( have two mating lines )
[04:19:06] <pfred1> well I'll still be able to unplug the female DB-25
[04:19:06] <Dave911> cradek: Is there a write up on the Touchy interface anywhere on the web? I thought there was something on the Wiki, but I couldn't find anything with a search.
[04:19:42] <skunkworks> hmm - were does the red wire go? http://www.electronicsam.com/images/KandT/conversion/ratsnest.JPG
[04:19:45] <cradek> more specifically what kind of write up?
[04:19:48] <skunkworks> hwere
[04:19:50] <pfred1> but the riser out of PCs is DB-25 to a 26 pin double header
[04:19:50] <skunkworks> where
[04:20:20] <cradek> how to set it up? how to use it?
[04:20:40] <cradek> pretty screen shots?
[04:20:45] <pfred1> skunkworks yummy
[04:21:07] <cradek> heh, good thing you won't need most of them! ... I hope
[04:21:27] <pfred1> cradek most people shouldn't be let anywhere near wires!
[04:22:03] <pfred1> I had a car like that once i gutted the whole harness and started from scratch
[04:22:58] <pfred1> * pfred1 likes the original green paint color better than the blue ....
[04:23:45] <skunkworks> cradek: yes - most of them.. Expecially if we get the accupins working
[04:25:54] <cradek> I hope you can do that
[04:26:08] <skunkworks> that will be phase II ;)
[04:26:56] <pfred1> skunkworks what was wrong with the institutional green the machine was painted it is so soothing?
[04:27:09] <pfred1> blue is jarring
[05:45:56] <dmz_> skunkworks: is that on a matsuura?
[06:24:15] <dmz_> http://www.hgrindustrialsurplus.com/sub/product_detail.aspx?id=30-955-001&searchtable=1&sortExpression=&SortASC=&pageSize=50&currentPageIndex=3&searchNAP=true
[06:24:28] <dmz_> $999 for a fanuc robot?
[06:24:49] <pfred1> dmz_ just imagine what its missing!
[06:25:32] <dmz_> yea machine moving company on each end plus truck shipping
[06:26:13] <dmz_> then parts on top of that
[06:34:21] <maxbots> Hi Folks, I'm having a problem, and hoping one of you may be able to offer me some advice.
[06:34:41] <maxbots> I'm running a G code file, and everything seems to be going along just fine
[06:35:08] <maxbots> Then midway through an op, it seems to just randomly loose it's place.
[06:35:52] <maxbots> The cutter is offsetting a couple inches aways from where it should be.
[06:36:15] <maxbots> The same problem hapened twice with the same file, and occurred at the same location.
[06:37:02] <maxbots> The onscreen display shows the cutter where it is supposed to be, but it is actually offset by a couple inches
[06:37:08] <nmen> nmen is now known as numen
[06:37:32] <maxbots> Anything I should look for that might explain such a problem?
[06:40:50] <maxbots> Here's the entire gcode file: http://pastebin.com/9FbAMLUu
[06:41:42] <maxbots> The error is happening midway through the third 2 1/2 axis facing op, which starts at line N1168
[06:47:32] <maxbots> biab... Gonna go run it again and see if I can note more accurately where the problem is occuring.
[07:10:03] <nmen> nmen is now known as numen
[07:17:39] <maxbots> Ok, well as you probably could have predicted, it worked perfectly that time.
[07:17:53] <maxbots> Only difference is I rebooted between runs.
[08:09:33] <nmen> nmen is now known as numen
[09:26:45] <MattyMatt> sweet. 2 broken 500mhz pc, but one revived 1.2 athlon w 512MB. liveCD now works :)
[09:30:17] <MattyMatt> now I just need to rig a standby switch to the ATX psu, and fashion a high amp ribbon cable for the Z motor out of mains flex and duct tape, and I'm ready for testing
[09:51:34] <nmen> nmen is now known as numen
[11:54:55] <renesis> emc on 500mhz sucks
[11:55:24] <renesis> well, livecd ubuntu emc at least
[12:00:01] <Jymmm> how much ram?
[12:00:30] <Jymmm> you need at least 256MB minimum for LiveCD
[12:20:54] <Valen> oh btw if any of you guys want DDR or SDRAM lemme know I've got a box of the stuff, just depends on shipping.
[12:29:30] <numen> does anyone have sdram 256 or 512mb with only 4chips?
[12:43:43] <Dave911> cradek: Hi.... Just an introduction, how it works, screen shots etc. I saw a write up but it didn't show any screen shots ..
[12:48:33] <Dave911> If you have a Fanuc robot like that, that thing would probably be worth it just for the parts.... I wonder if they will power it up where it is to see how functional it is... As I recall their loading fees are very reasonable.
[13:17:07] <MattyMatt> numen I doubt it. 512MB was a lot for sdram, I think mine is 16 chips
[13:18:34] <MattyMatt> yeah 16
[13:24:54] <numen> but it should be posssible to get with 4 chips
[13:25:27] <numen> this would be 64mx16 chips
[14:02:40] <MattyMatt> I doubt they actually make it anymore, it'll be all old stock
[14:27:01] <MattyMatt> bleh, no trace of a hal file for my HY-TB4DV-M driver
[14:27:49] <MattyMatt> who do I send it to when I've written it? these boards are all over ebay
[14:30:08] <MattyMatt> it needs a proper English manual writing too :)
[14:41:36] <clytle374> MattyMatt, might find an old guy in England that can still do proper English;)
[14:41:55] <the_Lamb> the_Lamb is now known as robotito
[15:38:12] <cradek> MattyMatt: what is it?
[16:01:22] <alex_joni> sounds like a 4 axis stepper control board
[16:01:50] <alex_joni> 12-36V, 3A/motor
[16:05:16] <jackc> i have one of those
[16:05:26] <jackc> MattyMatt: the stepconf makes it work perfectly
[16:05:59] <jackc> MattyMatt: all you need to care about is the pinout and the dip switches, the english is easy enough there
[16:06:10] <jackc> oh, and amp-enable
[16:30:17] <jackc> MattyMatt: if you have issues yell at me when im around, out and about for a bit now.
[16:37:39] <JT-Hardinge> don't you just hate it when you do a bunch of ladder and forget to save it :/
[16:37:47] <skunkworks_> heh
[16:37:59] <skunkworks_> cradek warned me about that...
[16:38:30] <atmega> save early, save often.
[16:38:43] <JT-Hardinge> heh
[16:39:10] <JT-Hardinge> good thing is it has only been a few minutes since I did that so I just might remember what I did :)
[16:39:35] <atmega> my lesson from 1980 or so, I always remember
[16:49:17] <alex_joni> save early, save often, and make a lot of backups
[16:49:37] <atmega> yeah, saving crap on top of your working copy isn't so hot
[16:49:52] <alex_joni> JT-Hardinge: you could just use git ;)
[16:50:00] <skunkworks_> I don
[16:50:01] <atmega> no git interface to the ladder editor?
[16:50:08] <skunkworks_> I don't git it.
[16:51:06] <JT-Hardinge> I have enough trouble with git :P
[16:53:19] <skunkworks_> JT-Hardinge: you seem to do just fine :)
[16:53:43] <JT-Hardinge> once I get all my little helpers setup I'm ok LOL
[17:04:24] <JT-Hardinge> SWEET! My Turret works and I only forgot to save it like 11 times :/
[17:06:44] <skunkworks_> sweet!
[17:08:08] <JT-Hardinge> and Axis correctly warns me if I try and load a tool not in my tool table :)
[17:11:31] <JT-Hardinge> not much left to sort out before making some chips :)

[19:11:27] <Danimal-office> JT-Hardinge, how's it going?
[19:12:40] <Danimal-office> Jymmm, both overpriced
[19:12:56] <Danimal-office> i paid $400 for that same grinder
[19:14:15] <Danimal-office> granted mine doesnt have the dro, but IMO that's useless on a manual grinder.
[19:14:45] <cradek> dro on a surface grinder?
[19:15:11] <Danimal-office> yea
[19:15:14] <Danimal-office> pointless
[19:15:37] <Danimal-office> i can *kinda* see it on an automatic unit
[19:16:11] <Danimal-office> but really, on a manual? it's not like you're feeding all that fast in the y axis. not too hard to keep an eye on the dial
[19:16:55] <JT-Hardinge> Danimal-office: good I have the turret going
[19:17:02] <Danimal-office> great!
[19:17:15] <Danimal-office> did you have to adjust the magnet at all?
[19:17:25] <JT-Hardinge> no
[19:17:32] <Danimal-office> cool
[19:17:52] <Danimal-office> did you use the hal component for the turret, or did you do it in ladder?
[19:18:08] <JT-Hardinge> I did the ladder like I normally do plc ladder
[19:18:22] <Danimal-office> cool
[19:18:27] <JT-Hardinge> I haven't tried the comp yet
[19:18:40] <Danimal-office> if it aint broke, dont fix it lol
[19:18:53] <Danimal-office> so you basically have a working machine, now huh?
[19:19:09] <Danimal-office> do you have a chuck or collets for it, and the tool holders?
[19:19:38] <Danimal-office> btw, does yours use oil or water solulable coolant?
[19:19:58] <JT-Hardinge> some odds and ends to go like the e-stop chain, the pressure switches, mount the monitor and keyboard clean this mess up etc
[19:20:07] <JT-Hardinge> I don't have a clue :)
[19:20:30] <JT-Hardinge> there is a copy of my ladder on the forum if you want to take a gander at it
[19:20:57] <JT-Hardinge> I have to run so talk to you later
[19:21:30] <Danimal-office> ok cool thanks
[19:21:32] <Danimal-office> adios
[19:22:22] <Danimal-office> cradek, what do you think it would take to get our machines water-solulable coolant worthy?
[19:23:00] <Danimal-office> better sealing on the compartments for the turret and resolver/tach stuff?
[19:24:09] <Danimal-office> brb, gotta restart this pc
[19:32:31] <Danimal-office> back
[19:32:46] <cradek> Danimal-office: no idea. I think the oil is needed for the Z slidey parts.
[19:33:09] <Danimal-office> it doesnt have a lube system for z?
[19:33:24] <cradek> yeah but I think the water would wash it all off
[19:34:12] <Danimal-office> hmm
[19:34:25] <Danimal-office> doesnt seem to wash it off the mill's ways
[19:34:29] <clytle374> Do they have wipers?
[19:34:32] <Danimal-office> yes
[19:35:05] <cradek> you have coolant running over your mill's ways?
[19:35:21] <Danimal-office> yea
[19:35:37] <Danimal-office> not intentionally, but it usually leaks some on there
[19:35:52] <Danimal-office> and all over the rest of the garage
[19:35:57] <cradek> that'd make me nervous :-)
[19:36:27] <Danimal-office> eh, they're prettyoverbuilt chromed box ways
[19:36:44] <clytle374> Rig up some covers, it should be good. Cutting oil in there isn't good either, unless you don't recirculate it.
[19:37:05] <Danimal-office> yea i could put on some bellows
[19:37:19] <Danimal-office> although the coolant eats those too lol
[19:37:33] <Danimal-office> it's just that the oil smokes up too much
[19:37:36] <clytle374> With good wipers, rust and parts hitting the ways will be your biggest concerns.
[19:37:46] <Danimal-office> my parts are kinda big
[19:38:10] <Danimal-office> yea
[19:38:23] <Danimal-office> it does seem to have pretty good wipers
[19:38:40] <Danimal-office> and not any areas for it to sit and pool up
[19:39:13] <clytle374> roll up covers can work okay too.
[19:39:47] <clytle374> depending on the machine obviously
[19:40:08] <Danimal-office> it may kill the lathe prematurely, but if it's used enough to wear it out, that means ii got my money's worth
[19:40:46] <Danimal-office> ways are perfect right now, so i got a few years lol
[19:40:52] <clytle374> What about the screws and thrust bearings?
[19:41:00] <Danimal-office> sealed up good
[19:41:30] <clytle374> Oil was often used because coolants used to suck soo bad
[19:41:43] <Danimal-office> i'm pretty sure the chnc's use water solulable coolant, and it's basically the same machine
[19:42:17] <clytle374> I've seen lots of cnc lathes with exposed ways run coolant.
[19:42:19] <Danimal-office> yea, i was thinking the warning label is on there because water solulable stuff wasnt so hot in the 70's
[19:42:38] <clytle374> there is a warning?
[19:42:41] <Danimal-office> yes
[19:43:32] <clytle374> I wonder if there is a dye you could add to be sure it doesn't get in the headstock
[19:43:46] <clytle374> never seen a specific warning before
[19:44:29] <clytle374> coolant in the headstock is real bad
[19:44:43] <Danimal-office> it says oil based cutting fluids reccomended for extended machine life
[19:45:25] <Danimal-office> doesnt say DO NOT USE WATER SOLULABLE COOLANT!!!!1!!11!
[19:45:53] <clytle374> oh, okay. Use good coolant! cheap stuff sucks
[19:46:09] <Danimal-office> yea
[19:46:19] <Danimal-office> trim sol
[19:46:28] <Danimal-office> is what i've always used
[19:46:36] <Danimal-office> smurf piss
[19:46:50] <clytle374> and check the headstock to be sure it isn't getting in there, can be real bad news.
[19:47:01] <clytle374> smurf piss is quality
[19:48:02] <Danimal-office> yea, expensive though. takes a lot of little blue guys to make up 5 gallons of it
[19:48:19] <clytle374> Smell like play-dough
[19:48:27] <Danimal-office> ha never noticed
[19:49:59] <clytle374> know where to get a cutter of gt2-2mm timing pulleys?
[19:50:07] <clytle374> cutter for
[19:50:11] <Danimal-office> no clue
[19:50:26] <clytle374> I can't get the pulleys I need.
[19:51:31] <clytle374> Had to change belt types since I found out the MXL belts are marginal at best
[19:52:27] <clytle374> more complicated profile.
[19:54:22] <Danimal-office> yea, sorry, i dont have a clue on that stuff
[19:55:02] <clytle374> seldom hurts to ask.
[19:59:17] <numne> numne is now known as numen
[20:22:34] <Guest459> Howdy all. Got a quick question on step config and micro stepping. Geting started guide says to use the value 2 for half stepping. I've got my stepper drives (Keling 4030) set to 1/64 micro stepping. Does that mean I plug in the value of 64 in the "Driver Micro Stepping" box?
[20:23:40] <cradek> yeah I think so
[20:23:58] <cradek> but if you want to go very fast, it might be better to set them to 4 or 8 or so
[20:24:37] <cradek> with this setting it takes 12800 step pulses to turn the motor one revolution - that's a lot of pulses and it will really limit your top speed.
[20:25:19] <Guest459> Okay, I'm not sure what speed I'll really end up with, but I'll start it at 1/8 microstep on the drivers first. Thanks!
[20:25:33] <cradek> welcome
[20:30:57] <Guest459> Also, I'm using a rack and pinion setup on the X axis, with a reduction of 3:1 from the stepper to the pinion. My mind seems to be brain dead this afternoon when it comes to math. The setup is supposed to give me 1.0472" per revolution. How do I convert that to revolutions per inch for the leadscrew pitch?
[20:31:27] <Guest459> Do I dived 1 by 1.0472?
[20:32:06] <Guest459> Oops, that should be divide, not dived...
[20:32:08] <clytle374> yes.
[20:32:13] <JT-Work> YES
[20:32:22] <JT-Work> dang caps lock key
[20:32:22] <Guest459> Thanks again!!!
[20:33:16] <JT-Work> Guest459: pay attention to the scale number and make sure that matches what you calculate
[20:34:58] <JT-Work> scale being the number of pulses to move one user unit
[20:36:05] <archivist> clytle374, they are hobbed so ask a hob manufacturer
[20:36:43] <numen> anyone here who has some sdram he dont needs?
[20:38:59] <Danimal-office> i have some ram, not sure if it's sdram, but it isnt ddr
[20:39:08] <Danimal-office> came out of a p3
[20:39:36] <numen> Danimal-office should be sdram if it was used with p3
[20:39:44] <numen> could you give me the chip numbers?
[20:40:24] <numen> cause i need 32M x16 chips
[20:41:08] <clytle374> archivist, thanks.
[20:41:28] <Danimal-office> not sure what i'm looking for
[20:41:36] <Danimal-office> what chip number?
[20:41:42] <Danimal-office> i'm not a computer guy
[20:41:57] <numen> the number which is printed on the top of the chip

[20:42:50] <numen> here you have the chips, the black ones next to the batterie, i need the number which is printed on the chip with white color
[20:43:04] <Danimal-office> 48lc32m4a2
[20:43:15] <numen> mhm these are 4bit chips...
[20:43:27] <numen> this dimm uses 16chips right?
[20:43:55] <Danimal-office> 18 for that one
[20:44:13] <numen> right, this is an reg ecc dim?
[20:44:43] <Danimal-office> hyb39s128800ct-7.5 for the second one...9 chips
[20:45:20] <numen> 16Mx8
[20:45:31] <numen> i need min 16Mx16
[20:45:45] <Danimal-office> and k4s280432d-tc75 for the third...18 chips
[20:46:26] <numen> 32Mx4
[20:46:53] <Danimal-office> thats all i got
[20:47:16] <cradek> if out of a P3 it's PC133 (or less likely PC100)
[20:47:17] <numen> none is right, thx for have a look at it
[20:47:24] <Danimal-office> pc133
[20:47:29] <Danimal-office> no prob
[20:47:41] <numen> i need for my nslu2
[20:47:50] <numen> which needs 16bit chips
[20:48:27] <Danimal-office> 16x72 wont work?
[20:49:57] <Danimal-office> one says 16x72 sdram
[20:50:21] <Danimal-office> 16mx72
[20:50:43] <numen> Danimal-office i dont need the whole bank, just 2 single chips of it
[20:51:03] <numen> but these chips have to be 16bit and the ones you gave me are 4 or 8bit
[20:51:35] <Danimal-office> i dunno, one has a sticker right on it that says 16mx72
[20:52:33] <numen> yes, but the sticker is for the whole dimm
[20:52:44] <Danimal-office> gotcha
[20:52:46] <Danimal-office> ok
[20:52:48] <numen> the nslu2 just use 2 of these 18 chips^^
[20:53:12] <Danimal-office> that one yas 9
[20:53:15] <Danimal-office> has
[20:53:19] <Danimal-office> but i gotcha
[20:54:03] <numen> it should just have 4 or 5chips
[20:54:05] <numen> i think
[20:54:08] <numen> but not shure
[20:56:24] <Danimal-office> it has 9
[20:56:46] <Danimal-office> i can count to at least 10, so i know it has 9 :)
[20:57:02] <numen> ^^
[20:59:59] <clytle374> numen, if you're going to be around a while, I'll go take a look in the barn.
[21:00:36] <numen> would be great
[21:01:00] <numen> what do you mean with a while? here its 10pm^^
[21:01:33] <Danimal-office> it's 1pm here
[21:01:41] <clytle374> I'm eating and it's pouring rain, ?
[21:02:09] <Danimal-office> it's 10am where he is
[21:02:16] <Danimal-office> i think.. or 11am
[21:02:30] <frallzor> http://www.vimeo.com/10096415 tadaaa my workplace :P
[21:03:20] <clytle374> 4pm here
[21:03:36] <Danimal-office> opps yea the other way around.
[21:03:44] <Danimal-office> 3 hours ahead
[21:03:54] <Danimal-office> how quickly i forget
[21:03:59] <numen> clytle374 where are u from?
[21:04:02] <clytle374> are these worth international shipping to yoy?
[21:04:02] <Danimal-office> frallzor, looks good!
[21:04:11] <clytle374> WV,USA
[21:04:22] <frallzor> 2/3 of 1/4 of all holes drilled now :P
[21:04:30] <frallzor> aka 2/12 :P
[21:04:54] <numen> wv?
[21:05:16] <clytle374> West Virginia
[21:05:24] <numen> ok^^
[21:05:33] <frallzor> 40 down, 200 to go
[21:05:56] <Danimal-office> lol
[21:06:05] <Danimal-office> damn lotta holes
[21:06:13] <frallzor> yuuup
[21:06:44] <frallzor> lotta holes *strokes the shotgun and lights a pipe*
[21:06:50] <frallzor> * frallzor is playing redneck
[21:07:51] <clytle374> pipe is out'a place
[21:08:08] <frallzor> *spits tobacco*
[21:08:11] <frallzor> better?
[21:08:38] <skunkworks_> cooks some meth?
[21:08:49] <frallzor> fondles an infant wife maybe? :P
[21:17:13] <MattyMatt> thanks for the replies earlier, guys. I had a nap
[21:19:54] <MattyMatt> it's stepconf time
[21:24:07] <bosko> Hello everyone!
[21:26:22] <clytle374> frallzor, yes
[21:26:34] <clytle374> skunkworks_, just trash at that point
[21:27:01] <clytle374> numen, sorry nothing but 8 and 16 chip sticks in the pc100 flavor
[21:27:44] <clytle374> frallzor, infant wife is limited to other countries.
[21:28:55] <MattyMatt> they don't know the law if they're infants
[21:29:04] <MattyMatt> chain em to the cellar
[21:29:36] <clytle374> numen, even looked through the table leg shims or target practice box. I have some old 486 memory though, big 8meg sticks.
[21:30:44] <MattyMatt> I've got piles of 64MB pc133/100
[21:31:23] <numen> clytle374 8chip could work, if they are duble sided
[21:31:25] <MattyMatt> they're the ones I collected after going round all my friends with the better ones I had :p
[21:31:51] <clytle374> numen, no single sided.
[21:31:57] <numen> MattyMatt only chips or complete dimms?
[21:32:06] <numen> clytle374 do you have chip number?
[21:32:11] <MattyMatt> complete dimms. all 8 or 16 chip
[21:33:18] <numen> MattyMatt 64mb are too small, these chips are allready soldred... need min 128mb dimm, better 256 or 512mb..
[21:33:26] <MattyMatt> I really don't think you'll find many 4 chip pre-ddr. it's too old
[21:33:30] <clytle374> hy57v658020a
[21:33:50] <clytle374> 48cl8m8a2
[21:34:36] <numen> MattyMatt these are possible to get, but not often used, cause they were expensive this time
[21:35:21] <numen> clytle374 these are both 8bit chips
[21:35:31] <clytle374> I know
[21:36:26] <numen> MattyMatt there exist 64M x16 chips such as 46cl64m16a2
[21:36:32] <MattyMatt> my DS cart has a 32MB 16 bit chip in
[21:36:55] <numen> but if you buy single chips they cost about 70$ each
[21:37:02] <numen> ds cart?
[21:37:42] <MattyMatt> nintendo devkit. they're about $20 now
[21:37:54] <numen> ok^^
[21:38:05] <numen> two of these chips would be nice^^
[21:38:59] <clytle374> numen, are you upgrading the board picuted earlier?
[21:39:39] <numen> clytle374 yes, this is the mainboard of a nslu2
[21:40:06] <clytle374> sadly I don't know what that is.
[21:41:26] <numen> nslu is something like a nas, but needs with usb connected memory device and is possible to run with debian
[21:44:44] <clytle374> I see.
[21:46:07] <Jymmm> SWPadnos: ping
[21:47:01] <SWPadnos> hi
[21:47:01] <alex_joni> lacks wifi though
[21:47:40] <MattyMatt> that's easily added
[21:47:53] <MattyMatt> through usb dongle if no other way
[21:48:25] <alex_joni> MattyMatt: yeah probably
[21:48:33] <alex_joni> I still prefer my asus wl-520gU
[21:50:14] <MattyMatt> I get cards with Realtek chips, because they are the only ones that can do Nintendo's bastardised version of the spec (generally known as nifi)
[21:51:52] <MattyMatt> I still think DS would make a good machine controller :) they're all the same so finite latency, and it has a touch screen
[21:53:11] <MattyMatt> you can even buy a thingy with fpga and 50 I/O lines
[21:53:26] <MattyMatt> that's $200 tho
[21:54:49] <bill2or3> and nintendo's would come choice of in 5 colors and 4 decorative graphics.
[21:57:08] <MattyMatt> they're quite tough for consumer goods. small screens are inherently less fragile
[21:57:44] <MattyMatt> smaller target area at least :)
[21:58:41] <MattyMatt> the new DSi lacks the gba slot though, so that would limit you to old ones in practice
[22:01:30] <MattyMatt> although you can buy an I/O card with ~12 lines for the new slot
[22:01:45] <skunkworks_> I would think the opas slot would more than make up for the lack of the sie write back.
[22:02:53] <MattyMatt> opas?
[22:03:17] <skunkworks_> * skunkworks_ is just making things up...
[22:08:22] <MattyMatt> ok :) point taken. I'm the only toymaker here
[22:08:40] <pfred1> MattyMatt what kinds of toys do you make?
[22:08:54] <MattyMatt> no big iron here until I get my own workshop
[22:09:15] <pfred1> MattyMatt oh you mean small format CNC?
[22:09:19] <MattyMatt> video games, and I'm planning to make robots
[22:09:35] <MattyMatt> and small format CNC :)
[22:09:39] <pfred1> MattyMatt thats what I call my CNC project sometimes too
[22:09:43] <pfred1> the robot
[22:09:50] <MattyMatt> it's accurate
[22:10:14] <pfred1> well I did the reverse art for my parallel port board
[22:10:52] <pfred1> this is going to be easy to assemble I think
[22:11:52] <pfred1> MattyMatt what'd you do for a parallel port break out board?
[22:11:59] <MattyMatt> damn no isa slot on my emc machine
[22:12:14] <pfred1> MattyMatt you want to use PCI anyways I think
[22:12:42] <MattyMatt> I have a VLB io card :p
[22:13:10] <pfred1> some PCI IO expansion cards are as little as $7
[22:14:41] <alex_joni> good night all
[22:14:43] <pfred1> though I only found recomendation for one particular board chip so far
[22:15:08] <pfred1> and the board i found said chip on isn'texactly the cheapest IO card I've seen
[22:15:19] <pfred1> it was $29
[22:15:48] <pfred1> which lead me to register at linuxcnc and ask a FAQ question there
[22:17:45] <MattyMatt> 2 port one on ebay :) http://cgi.ebay.co.uk/PCI-PARALLEL-PRINTER-2-PORT-CARD-SUPPORT-VISTA-FREE-S-H_W0QQitemZ110499638575QQcmdZViewItem
[22:18:28] <bill2or3> Does anyone know how to identify the tooth-profile of an unidentified timing pulley? (so I can get a matching belt..)
[22:19:32] <pfred1> bill2or3 I've read enough about timing belts to know that I don't know much about them or that there's a lot to them take your pick
[22:20:07] <bill2or3> heh. I guess I just look really closely, and make a best guess, huh?
[22:20:25] <pfred1> bill2or3 there are detailed documents about timing belts
[22:20:33] <pfred1> like 150+ pages long
[22:20:46] <pfred1> and from looking at them I figure there's 3 major kinds
[22:21:07] <pfred1> two with trapezoidal profiles and one with a round lock
[22:21:54] <pfred1> bill2or3 are the teeth basically square looking?
[22:22:30] <bill2or3> * bill2or3 gets a loupe
[22:22:37] <pfred1> they're tiny?
[22:22:52] <pfred1> that was going to be the second question
[22:23:02] <bill2or3> yeah, it's a pulley mounted on a nema23 tepper
[22:23:04] <bill2or3> stepper.
[22:23:30] <bill2or3> they look square, or very steep trapezoid.
[22:23:48] <pfred1> yeah the round lock ones are very round and not too tiny
[22:23:53] <MattyMatt> I guess pitch, width, and basic tooth shape are the only parameter that matter
[22:24:15] <pfred1> by and large there's only like 3 profiles I mena there's more but some interchange
[22:24:37] <pfred1> big and little square ones and the round lock
[22:24:57] <pfred1> he's got the little square one it sounds like
[22:25:28] <pfred1> let me see if I can find the one pdf file I have about it and the name
[22:25:41] <MattyMatt> yeah like a printer one. usually 2mm pitch but there's a few of them too
[22:26:36] <bill2or3> I dont have calipers here to measure , but it's a tiny pulley,
[22:26:38] <MattyMatt> japanese printers are all metric
[22:26:50] <bill2or3> maybe it'll be on the motor's datasheet, if I can find that.
[22:26:52] <MattyMatt> get the radis and count the teeth
[22:28:20] <MattyMatt> radius/circumference
[22:31:45] <JT-Hardinge> cradek: Danimal-office: does your lathe have a spindle brake?
[22:31:59] <Danimal-office> yes
[22:32:02] <Danimal-office> well, had
[22:32:12] <Danimal-office> i think we both took ours off
[22:32:40] <JT-Hardinge> ok
[22:32:50] <Danimal-office> i have a braking resistor, which is good enough
[22:32:56] <JT-Hardinge> I was just wondering how you handled it
[22:33:00] <Danimal-office> if it stops any faster, the chuck comes loose
[22:34:06] <pfred1> bill2or3 hey i found it I think
[22:34:11] <bill2or3> ?
[22:34:34] <pfred1> although stupid assed google couldn't
[22:34:41] <pfred1> let me put it on filebin
[22:35:01] <bill2or3> kk
[22:35:53] <pfred1> bill2or3 http://filebin.ca/kyfrj/Timing_20Belts.pdf
[22:37:07] <bill2or3> nice, that looks great.
[22:37:19] <pfred1> bill2or3 helps you figure it out?
[22:37:30] <bill2or3> yeah, I think it will.
[22:37:42] <pfred1> bill2or3 its pretty damned involved but to just figure out which it is it may help
[22:38:02] <bill2or3> once I get the sizes measured I'm going to hit sdp-si.com and see how many possible choices there are, that should narrow it down close enough to make a guess.
[22:38:34] <pfred1> seems to me its the 3 or 5 mm GTs ot that power lok
[22:39:14] <pfred1> power grip whatever it is
[22:42:39] <clytle374> Sounds like GTs, but I'm still confused. I think HTD is compatible with the GT2
[22:43:34] <pfred1> clytle374 it does seem like a couple mesh with each other to me too but timing belts are more complicated than they need to be
[22:44:15] <pfred1> best place i found for surplus for them seems to be amazon too go figure
[22:44:31] <pfred1> all the other surplus places act like they got gold or something
[22:47:17] <MattyMatt> htd is 1/5" not 5mm iirc
[22:47:48] <pfred1> MattyMatt says here 5mm
[22:47:54] <wendtmk> Hi everyone, question on the parallel port. Should it be set to epp, spp or ecp? Or something else?
[22:48:01] <bill2or3> epp afair.
[22:48:08] <pfred1> yeah EPP is what I see
[22:48:23] <clytle374> pfred1, I read that in a manual, don't ask where, I forgot.
[22:48:28] <pfred1> wendtmk but it should be more clear in the documentation
[22:48:59] <pfred1> clytle374 yeah I've been dealing with that recently myself and I guess they just assume everyone knows
[22:49:28] <MattyMatt> pfred yeah I was thinking of the other one Tooth form: MXL, 2.03mm (0.08") pitch
[22:49:50] <pfred1> MattyMatt you grabbed the pdf too?
[22:49:55] <wendtmk> Okay, thanks. I finally got my pooter hooked up to the controller box, and am walking through stepconf, and when I go to test each axis, nothing moves. using Keling 4030 drivers, cnc4pc bob, and wiring is per kelling instructions. When I power up, I can hear power getting to the steppers, but when I try to test the steppers after configuring, they're just locked up. No movement.
[22:50:09] <MattyMatt> pfred1 no, but I will :)
[22:50:33] <clytle374> I used the sdp-si sight to download the cad drawing of the pulleys to figure out whats what
[22:50:55] <pfred1> clytle374 that may be where i grabbed this pdf from I can't remember
[22:51:26] <pfred1> clytle374 all I know is its a lot more than i ever wanted to know about timing belts!
[22:51:30] <bill2or3> looks like about 10 teeth per inch.
[22:51:34] <MattyMatt> I got the info on HTD and MXL from http://www.motionco.co.uk/timing-belts-timing-belts-c-25_45_27.html
[22:52:08] <pfred1> bill2or3 section 7 page 13 gives nice tooth profiles
[22:53:28] <clytle374> This is good to http://www.hpcgears.com/newpdf/technical_timing.pdf
[22:53:28] <bill2or3> ah, that helps.
[22:54:02] <bill2or3> I have one of those toy microscope cameras at home, once I get some good pictures of the teeth I should be able to tell.
[22:54:09] <pfred1> * pfred1 wgets clytle374's URL ....
[22:54:52] <bill2or3> I think this motor is shot, bleh
[22:55:02] <pfred1> bill2or3 stepper?
[22:55:06] <bill2or3> it's all tight & hard to turn.
[22:55:08] <bill2or3> yeah, stepper
[22:55:14] <pfred1> bill2or3 hold the wires apart
[22:55:22] <bill2or3> I got two, the other one feels fine.
[22:55:33] <bill2or3> it's wired with a plug, so I assume the wires aren't touching.
[22:55:44] <bill2or3> anyway, it's tighter than that would cause.
[22:55:46] <pfred1> bill2or3 try this wire them color to color then turn the shaft on one
[22:55:58] <pfred1> bill2or3 if the other motor turns they're both good
[22:56:21] <bill2or3> I tried that on the other motor, just to get a feel for how tight it was, and the 'good' one feels a lot looser than the 'bad' one.
[22:56:21] <pfred1> bill2or3 no shorted stepeprs lock up
[22:56:38] <pfred1> the more they lock up the better they are!
[22:56:44] <MattyMatt> if the resistances look OK, plug it in and see. maybe it needs running in
[22:56:48] <bill2or3> heh
[22:57:01] <bill2or3> it's a used motor, so who knows what condition its in.
[22:57:11] <pfred1> you will
[22:57:26] <pfred1> phasing them without documentaiton is a pain
[22:57:30] <bill2or3> It's one of the vextas here --> http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=260561189835
[22:58:07] <pfred1> bill2or3 ah the good old blurry ebay ad picture deal?
[22:58:09] <bill2or3> they arrived still hooked into the drivers, & the plugs are labeled.
[22:58:23] <bill2or3> yeah, I lucked out because that picture is so crappy. :-)
[22:58:37] <pfred1> bill2or3 you'll find out
[22:58:45] <MattyMatt> nice buy :)
[22:58:59] <pfred1> MattyMatt yeah if its not all melted to slag
[22:59:12] <bill2or3> if I wire them color-to-color and turn the 'good' motor nothing happens, but if I turn the 'bad' motor, the good one moves, a little.
[22:59:24] <bill2or3> I bought it for the drivers anyway, so the motors are just frosting.
[22:59:25] <MattyMatt> 3 out of 4 is still a bargain
[22:59:27] <pfred1> bill2or3 that is not a good sign
[22:59:43] <bill2or3> they're in nice milled aluminum mountings, too.
[22:59:47] <pfred1> the one should mirror the other
[22:59:54] <bill2or3> yeah, I'm guessing it's shot.
[23:00:02] <bill2or3> Oh well, I can still use the pulley and mounting.
[23:00:21] <pfred1> are the drivers geckos?
[23:00:39] <bill2or3> Centents
[23:01:34] <bill2or3> what's teh failure-mode for steppers anyway? Do the bearings usually go bad, or is something else more common?
[23:01:56] <pfred1> I'd guess with amateurs hooking them up burnt windings
[23:01:58] <MattyMatt> I guess coils get so hot they deform
[23:02:10] <clytle374> Depends on how tight the belts were.
[23:02:34] <pfred1> lets face it there's a lot of ways to mess a stepper up
[23:02:47] <clytle374> Does the shaft flop around?
[23:02:51] <pfred1> I hear stay away from medical pulls too the radiation wrecks the motors
[23:03:03] <MattyMatt> ingress of dirt
[23:03:27] <clytle374> I doubt the radiation is an issue
[23:03:48] <pfred1> clytle374 I know a guy who does medical imaging he says stepeprs last like 6 months in the environment
[23:04:09] <pfred1> clytle374 he's one of 200 certified worldwide to do tech work on the systems so he should know
[23:04:20] <clytle374> Ever here those things chunck?
[23:04:47] <pfred1> clytle374 but they're as clean when they come out as when they go in :)
[23:04:49] <clytle374> Rads are too low to effect the motors. or are you talking xrays? Still shouldn't effect them
[23:05:01] <bill2or3> the shaft is not loose.
[23:05:05] <pfred1> clytle374 yeha he says rads ruin them
[23:05:26] <pfred1> they demagnetize maybe its in the MRI units they get messed up
[23:05:35] <pfred1> he works on those too
[23:05:50] <bill2or3> mri damage would make more sense.
[23:06:17] <clytle374> that would do it, rads used in medical stuff aren't big enought for metal cased motors
[23:06:44] <pfred1> clytle374 you got to remember the motor is in there 24/7 it takes a beating
[23:06:46] <MattyMatt> ohio has 2 nuclear plants
[23:07:10] <MattyMatt> fuel rod actuators would get a dose
[23:07:13] <pfred1> all I know is I wouldn't want medical pull stuff
[23:08:17] <clytle374> Still, if the motor wasn't inside a lead box with the bad stuff, it isn't going to hurt it. fuel rods are an extreme example
[23:08:20] <clytle374> blb
[23:08:20] <pfred1> there's a thread on cnczone about guys stripping commercial copiers they're getting fat hauls
[23:09:34] <Jymmm> Man, I wish I had the room for it... http://sfbay.craigslist.org/sby/tls/1641172166.html
[23:10:45] <pfred1> Jymmm looks more like a dust recirculator to me :)
[23:11:01] <MattyMatt> mount it outside at the roofline
[23:11:01] <Jymmm> why do you say that?
[23:11:18] <pfred1> MattyMatt so your neighbors can choke too?
[23:11:20] <Jymmm> As long as the bag isn't torn.
[23:11:52] <MattyMatt> even carpet vacuums are bagless these days
[23:12:18] <Jymmm> No, the BAG is for air release, the drum collects the dust
[23:12:24] <MattyMatt> vortex seperators work great for sawdust
[23:12:33] <pfred1> cyclones
[23:12:52] <MattyMatt> them :) no coffee since nap. rectifying
[23:13:19] <pfred1> this thing appears to be missing the vortex stage
[23:14:13] <pfred1> if the dust is really bad i put a box fan in a window
[23:15:47] <pfred1> Jymmm it is a nice motor impeller is probably nice too
[23:15:55] <Jymmm> pfred1: If it has blades under the lid, that's all it really needs.
[23:16:04] <Jymmm> For $50, not bad at all
[23:16:18] <Jymmm> can't get the drum or motor for that.
[23:16:41] <Jymmm> Heh, wonder how well it work for a vacuum table
[23:17:03] <Jymmm> 1HP should suck harder than a $3 whore on free BJ day!
[23:17:08] <pfred1> Jymmm you'd better get one of them alarm me pendants if yo utry that stunt!
[23:20:22] <pfred1> so does anyone here have any experience with PCI I/O cards and emc2?
[23:20:42] <skunkworks_> like?
[23:21:03] <pfred1> skunkworks_ like which work and which don't I want ot buy one
[23:21:08] <pfred1> or do they all work?
[23:22:10] <skunkworks_> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?EMC2_Supported_Hardware
[23:22:15] <skunkworks_> I like mesa..
[23:22:25] <skunkworks_> bbl
[23:22:26] <pfred1> skunkworks_ I mean parallel port cards
[23:24:28] <pfred1> I've seen the recomendationfor the netmos 9815 but I've only seen one card that has that chip on it
[23:24:46] <pfred1> I was just wondering if i have any other options is all
[23:31:14] <MattyMatt> you could make one out of ttl chips, if you had one of those PCI prototyping boards
[23:31:47] <pfred1> MattyMatt prices are reasonable enough for PC components
[23:32:00] <MattyMatt> yeah nobody solders anymore :)
[23:32:16] <pfred1> MattyMatt I solder just not when it isn't worth my time to do so
[23:32:32] <pfred1> MattyMatt if i can buy a board for $7 I cannot compete with that
[23:32:41] <MattyMatt> at $7, they are disposable
[23:33:04] <pfred1> but with the information i have I am just taking a shot in the dark for it working now
[23:33:16] <pfred1> for $29 I can get a board i know will work
[23:33:30] <pfred1> but I'd prefer having all of my options open to me
[23:34:08] <MattyMatt> I'd start with a $7 one fo sho, because if it burns out occasionally you can replace it
[23:34:28] <pfred1> ther is no guarantee the $7 one will work at all
[23:34:50] <pfred1> so it could be $7 down the drain
[23:35:04] <pfred1> and the time to get it and time to replace it too
[23:35:57] <pfred1> so far all I've seen is one line about one particular chip working well with EMC and I'm finding it hard to believe that someone doens't know of something else that works
[23:35:58] <MattyMatt> I can't see why it wouldn't. maybe the $29 has extra pins, or is especially noise resistant, but otherwise a parport is a parport
[23:36:22] <pfred1> far from it not all output 5 volts even
[23:36:56] <MattyMatt> they should do. old printers need 5V signals
[23:37:00] <pfred1> http://www.linuxcnc.org/component/option,com_xfaq/task,answer/Itemid,5/catid,7/aid,11/lang,english/
[23:37:15] <pfred1> that says others do not implement EPP correctly
[23:37:30] <pfred1> doesn't say which others but implies there are some that don't
[23:39:36] <MattyMatt> if it has a grater than 7/29 chance of working, it's a wise gamble
[23:39:36] <pfred1> oh well I didn't think it an unreasonable request for information I guess I was wrong
[23:40:33] <pfred1> typically I do not gamble unless the odds are 100% in my favor of winning
[23:40:43] <pfred1> and so far its been working pretty good for me
[23:42:39] <MattyMatt> and you get less clutter of semi-junk :)
[23:43:59] <MattyMatt> I'll gamble on anything except hard drives. I want them shiny & new and not via mail
[23:44:13] <pfred1> I guess I'll have to keep on looking for this one esoteric chip on a dead interface board that is getting harder and harder to find
[23:44:40] <pfred1> I found one but one isn't much of a choice to me
[23:44:46] <clytle374> cow is milked. I've got some stepper laying around from an old HP tape transport, maybe I should look and see if there are useful.
[23:45:17] <pfred1> clytle374 you use plug in parallel port card?
[23:45:30] <clytle374> no, mesa pci
[23:45:45] <clytle374> just thinking I should get them out of the barn
[23:45:55] <pfred1> clytle374 yes I'm just looking to go parallel port interface for now
[23:46:16] <Kirk_Wallace> Hello. I need a little reminder of how to install and run AXIS on a remote userland only networked PC.
[23:46:43] <pfred1> Kirk_Wallace you want to do a remote X session?
[23:47:11] <Kirk_Wallace> I want to stream NML.
[23:48:51] <Kirk_Wallace> I want to just install AXIS without any of the realtime stuff.
[23:49:10] <clytle374> you mean simulator mode?
[23:49:24] <pfred1> clytle374 he wants to run axis all by itself
[23:49:37] <pfred1> I think
[23:50:27] <clytle374> If remotely, I'm interested. remote X isn't so hot on my network
[23:50:46] <pfred1> clytle374 what seems to be the problem?
[23:50:57] <pfred1> clytle374 people been doing remote X sessions since the 80s
[23:51:23] <clytle374> slow performance. wireless 54 Mb/s
[23:51:30] <pfred1> in fact X was designed for it and thats the only way they used to do it
[23:51:44] <Kirk_Wallace> I am revisiting a setup I did a while back: http://www.wallacecompany.com/machine_shop/EMC2/remote_notes.html
[23:51:46] <clytle374> still sucks for me.
[23:52:20] <pfred1> clytle374 well we did have a lot simpler window managers back then
[23:52:26] <Kirk_Wallace> But this had a full install on both PC's
[23:52:57] <Kirk_Wallace> I would like to keep the remote as a standard PC
[23:53:27] <pfred1> Kirk_Wallace I'm not 100% sure but I believe axis is just a front end and needs a lot of EMC to run
[23:53:34] <pfred1> if not all of it in fact
[23:54:19] <clytle374> shouldn't be all that much, it will run without realtime. just need to link the 2 pieces together.
[23:54:30] <pfred1> Kirk_Wallace you know like there's 5 different front ends and axis is one of them?
[23:54:54] <bill2or3> clytle, have your tried vnc?
[23:55:16] <bill2or3> it worked better than X-forwarding for me.
[23:55:42] <Kirk_Wallace> TkEmc will run stand alone, but at the time some tweaks where made to AXIS, but I didn't follow up on it.
[23:56:01] <clytle374> bill2or3, no I haven't. But will now that you brought it up.
[23:56:18] <bill2or3> give it a shot.
[23:56:31] <bill2or3> set your wallpaper to a single color.
[23:57:04] <pfred1> bill2or3 real men run X Window with weave background!
[23:57:10] <clytle374> did that first off, window animations off is important too.
[23:57:51] <bill2or3> yes, and CDK
[23:58:08] <clytle374> CDK?
[23:58:14] <pfred1> if you ever want to get certifiable use TWM
[23:58:24] <bill2or3> a WM that was on SunOS, pre-twm
[23:58:33] <Kirk_Wallace> VNC worked for me too, but then the host need to run all of EMC2 plus VNC. It seems with streaming NML, I can shut down the host UI and save on resources.
[23:58:49] <pfred1> I ran TWM for about 2 weeks and got worried when I started actually enjoying it!
[23:59:22] <pfred1> I find it amazing that EMC2 uses Gnome
