[00:19:13] <dmess> hi all
[01:44:50] <jepler_> jepler_ is now known as jepler
[12:46:14] <BigJohnT> If you set G64 P0.001 in a program does it get set back to just G64 without a P value after M2?
[12:53:45] <alex_joni> nfc
[12:54:22] <BigJohnT> ?
[12:54:28] <alex_joni> nf fscking clue
[12:54:34] <alex_joni> no ..
[12:54:43] <BigJohnT> LOL
[12:55:11] <BigJohnT> I could not tell by looking at the active g code list...
[13:00:19] <alex_joni> it might be not working correctly atm
[13:06:41] <cradek> hi from some other state - I forget which - it was late
[13:06:49] <cradek> I'm off
[13:07:00] <BigJohnT> ok
[13:07:57] <alex_joni> haha
[13:24:05] <_epineh> Hey all
[13:24:20] <BigJohnT> hey
[13:25:01] <_epineh> got my machine goin ! :_)
[13:26:07] <BigJohnT> cool, got pics?
[13:26:35] <_epineh> ya but only on cnczone
[13:27:13] <BigJohnT> what's the link
[13:27:14] <_epineh> nice to be able to talk here on the machine's controller PC :)
[13:27:26] <_epineh> 1 min...
[13:28:10] <fenn_> fenn_ is now known as fenn
[13:28:11] <_epineh> http://www.cnczone.com/forums/showthread.php?t=22101
[13:28:25] <_epineh> it has been a long build
[13:30:32] <BigJohnT> cool machine
[13:31:15] <_epineh> thnx, its a bit slow using threaded rod but it is quite heavy and rigid
[13:31:41] <BigJohnT> how does it cut?
[13:32:12] <_epineh> no prob, had it working using steppers but just tonight got it going using servo
[13:32:16] <_epineh> 's
[13:32:28] <BigJohnT> cool
[13:32:37] <_epineh> I milled a few PCB's and they turned out well
[13:32:59] <_epineh> so it mustn't be too out of shape
[13:33:08] <_epineh> haven't done aluminium yet
[13:34:23] <_epineh> gotta get my head around offsets now, not used to having a working machine, lol
[13:35:00] <BigJohnT> tool diameter offsets?
[13:35:58] <_epineh> nah, just zeroing, I was using Deskcnc previously and it zero's a little differently to EMC
[13:36:11] <_epineh> I just have to RTM
[13:36:35] <BigJohnT> for touching off on the edge of the part?
[13:37:39] <_epineh> yeah, I want to zero the machine coords, not set an offset
[13:37:54] <_epineh> I don't have homing switches installed yet... on the to do list
[13:37:58] <rayh> _epineh, Do you have real home switches on it?
[13:38:07] <rayh> Oh you read my mind.
[13:38:13] <_epineh> heh
[13:38:37] <rayh> If not, just put the tool where you want zero and press home.
[13:38:39] <_epineh> it is still a work in progress
[13:38:42] <BigJohnT> home/limit switches are nice
[13:39:57] <BigJohnT> morning Ray
[13:40:34] <_epineh> ahh, that did it, I thought it would try to do a homing move if I did that
[13:40:37] <rayh> Hi John
[13:41:04] <BigJohnT> _epineh: only if you set up homing in your ini file
[13:41:08] <rayh> I was wondering how you'd set up your ini for homing. I
[13:41:30] <rayh> oops. typoing again.
[13:42:10] <BigJohnT> here is how I used one switch for limit and homing on the X and Y axis http://i47.photobucket.com/albums/f163/johnplctech/Plasma%20Cutter/Plasma006.jpg
[13:42:46] <rayh> brb
[13:43:05] <BigJohnT> mmmm, bacon smell drifting down the stairs
[13:47:03] <BigJohnT> bbl
[13:47:41] <archivist> * archivist just knibbled bacon fries
[13:47:42] <_epineh> I still have to read up a little
[13:48:11] <_epineh> and install homing switches
[13:48:52] <_epineh> oops
[13:51:01] <_epineh> well its been a long day here, I am going to crash, thanks for the help :)
[13:52:16] <_epineh> bye
[14:37:46] <fragalot> mmm bacon
[14:39:58] <fragalot> BigJohnT: that plasma cutter looks great o.0
[14:45:20] <BigJohnT> fragalot: thanks
[14:45:33] <fragalot> how much time did you put into that thing
[14:46:01] <BigJohnT> I really don't know how many hours I spent on the construction
[14:46:16] <BigJohnT> I started last winter I think
[14:49:42] <BigJohnT> did you see the videos
[14:49:45] <fragalot> no?
[14:50:15] <BigJohnT> http://wiki.linuxcnc.org/cgi-bin/emcinfo.pl?Videos#Plasma_cutting
[14:54:23] <fragalot> is that the real speed?
[14:55:08] <fragalot> (first vid)
[14:55:30] <BigJohnT> yes, it will go > 500 IPM
[14:55:49] <fragalot> that last vid is quite impressive,.. nice smooth motion,...
[14:56:04] <BigJohnT> thanks
[14:56:22] <fragalot> I'm jealous
[14:56:23] <fragalot> :p
[14:56:25] <anonimasu> :)
[14:56:37] <BigJohnT> :)
[14:56:49] <fragalot> * fragalot makes miniature copy with a magic marker and lego technics
[14:57:53] <BigJohnT> take some pictures
[14:58:08] <fragalot> hehe, i'd need lego technics first
[14:58:08] <fragalot> :p
[14:58:28] <fragalot> I'm just hunting down my autodesk cd's so i can whip up a design
[14:58:38] <alex_joni> fragalot: check out alibre :)
[14:58:47] <fragalot> *googles*
[14:59:13] <fragalot> *downloads*
[14:59:13] <alex_joni> win only, but free for 3D stuff
[14:59:54] <fragalot> I used to make a 3D mockup in C4D, and then do the schematics in autocad,.. if i decided to make a schematic :/
[15:00:28] <fragalot> I'm the type of person that just, sketches something out, roughly, and then starts making it up as he goes,.... then end up beeing stuck, give up, go home, go back, pick up the angle grinder,.... :p
[15:00:45] <alex_joni> :-)
[15:05:42] <fragalot> lovely, download speed going up, and so is the time remaining
[15:05:45] <fragalot> *confused*
[15:46:03] <fenn> extra special relativity
[15:48:17] <alex_joni> spatial
[16:08:43] <fragalot> alex_joni: mm, I like alibre sofar
[16:08:54] <fragalot> does it produce decent schematics?
[16:10:47] <fragalot> need to get used to working the 3D view hto :p
[16:11:53] <archivist_ub> I hardly can think 2d anymore
[16:12:37] <fragalot> I just mentally convert 2D schematics to 3D aswell,.. makes things easy :)
[16:17:28] <dmess> Hi all
[16:18:13] <dmess> has any one used Paypal on an Ubuntu system??? my box dont seem to like it
[16:18:36] <fragalot> works for me on Gentoo, so don't see why ubuntu wouldn't
[16:21:08] <anonimasu> paypal?
[16:21:31] <anonimasu> that should work for any browser that supports ssl
[16:30:56] <rayh> I've done some paypal work with 8.04 here.
[16:31:11] <fragalot> /CALC 800-(2x17)
[16:31:15] <fragalot> wups,s orry
[16:45:07] <dmess> im on 6.06...
[17:08:01] <dmess> and set to use ssl 3.0
[17:10:44] <fragalot> O.O
[17:10:48] <fragalot> alibre just closed on me
[17:10:49] <fragalot> >.>
[17:29:23] <anonimasu> :/
[17:29:34] <anonimasu> you should enable the auto backup feature.
[17:30:04] <anonimasu> :)
[17:32:25] <fragalot> i did ;)
[17:32:32] <fragalot> its just,.. not nice of it to just close on me :p
[17:38:10] <jmkasunich> new toy: http://www.hgrindustrialsurplus.com/search-products/product-detail.aspx?id=21-217-073&searchtable=2&sortExpression=&SortASC=&pageSize=50&currentPageIndex=0
[17:40:03] <fragalot> \o/
[17:40:35] <jmkasunich> like all grinders, it weights about twice as much as you'd think
[17:40:44] <jmkasunich> gotta figure out how to unload it and get it in the basement
[17:40:55] <fragalot> I don't even know why i'm currently designing a plasma cutter / plotter / mill thingy... I know i won't make it anyways after i'm done
[17:40:58] <fragalot> >.>
[17:41:09] <fragalot> jmkasunich: yeah, machines tend to do that :p
[17:41:54] <fragalot> I got surprised by the strength of sheet metal a while back.. 2mm thick, tried to bend it 90 degrees.... even standing onto it, and jumping with 2 people didn't work, lol
[17:42:20] <jmkasunich> there was a really nice larger one there - I was sorely tempted, but it would have been a "rent a trailer to get it home" and "keep it in the garage and fight rust" one
[17:42:32] <fragalot> haha
[17:42:58] <fragalot> somehow, things don't rust in my garage.. kinda weird
[17:43:07] <jmkasunich> unfortunately they do in mine
[17:43:13] <jmkasunich> especially in the sprin
[17:43:16] <jmkasunich> spring
[17:43:37] <jmkasunich> 1800 lbs of cold cast iron winds up dripping wet on the first warm moist day
[17:43:47] <fragalot> :/
[17:47:07] <archivist_ub> time to insulate the garage nice toys only allowed
[17:47:20] <fragalot> haha
[17:47:29] <jmkasunich> one of these days - insulation and heat
[17:48:41] <jmkasunich> my other purchase: http://www.hgrindustrialsurplus.com/search-products/product-detail.aspx?id=12-275-094&searchtable=2&sortExpression=&SortASC=&pageSize=50&currentPageIndex=0
[17:48:46] <jmkasunich> 400W, 50,000 RPM
[17:49:21] <fragalot> sad that most things are only made for 30k rpm huh
[17:49:21] <fragalot> :p
[17:49:43] <jmkasunich> the motor is a 300Hz 3-phase induction motor, to be used with a VFD
[17:50:21] <fragalot> o.0 the things in the picture just looks like an oversized dremel
[17:50:46] <jmkasunich> in a way they are
[17:51:06] <jmkasunich> but a dremel has a brush motor, and mediocre bearings
[17:51:20] <fragalot> and no gears in it,.. direct drive
[17:51:28] <jmkasunich> this has an induction motor, about 3x the power, and approx 3:1 step up gears to a nice spindle
[17:51:47] <archivist_ub> ive had a dremel commutator segment fly off
[17:51:57] <fragalot> 3x more power, and stepping up the speed 3x via gears just ends up in less power doesn't it
[17:52:07] <jmkasunich> no
[17:52:37] <jmkasunich> power is the product of speed and torque, when you step up speed, torque drops, but the product remains the same
[17:52:56] <fragalot> point taken
[17:53:17] <fragalot> (altho gears aren't 100% effective, thus,.. I win! :p)
[17:55:23] <jmkasunich> off to mow the grass :-(
[17:55:47] <BigJohnT> its too hot for that here
[17:55:56] <archivist_ub> whats grass?
[17:56:01] <fragalot> it's always bad weather to do it :;p
[17:56:24] <jmkasunich> its too hot here too, but I didn't do it last week
[17:56:26] <fragalot> archivist_ub: a type of infestacious plant that we've agreed on using to cover plain dirt
[17:56:44] <archivist_ub> * archivist_ub uses weeds
[17:56:45] <BigJohnT> grass is what comes before bushes that come before trees if you don't mow it...
[17:56:53] <jmkasunich> it keeps down the weeds, which is good because the weeds gro faster than the grass does
[18:00:51] <fragalot> I prefer fire.
[18:00:51] <fragalot> :)
[18:16:41] <fragalot> what do you guys reckon the torque should be of a stepper motor for a desktop sized CNC mill (axis)
[18:22:06] <BigJohnT> that would depend on the friction, cutting loads, gear ratios, etc.
[18:22:21] <archivist_ub> and size of mill
[18:22:40] <BigJohnT> I built a 10' desk once
[18:23:26] <archivist_ub> Im using 180 nm for x,y and 330nm for Z and dunno for A
[18:23:41] <archivist_ub> 220nm for Z
[18:24:08] <BigJohnT> is that holding torqe?
[18:24:15] <archivist_ub> yes
[18:25:54] <archivist_ub> Im in this weekend to finish the Z so I can screw mill
[18:26:09] <BigJohnT> the only problem with that value is it is a measure of standing still not how much work it can do
[18:26:15] <BigJohnT> cool got any pics
[18:27:01] <archivist_ub> not yet and doing some server rework to get sites and pics backup
[18:35:42] <jmkasunich> hmm, this looks almost exactly like my grinder:
[18:35:42] <jmkasunich> http://www.nolansupply.com/bysubcategory.asp?category=Machinery&supercategory=Grinders+%2D+Surface+%2D+Targa&subcategory=Targa+Hand+Operated+Surface+Grinder&type=False&specs=True
[18:35:47] <jmkasunich> except its a mirror image
[18:35:54] <jmkasunich> I wonder if they flipped the photo?
[18:36:05] <jmkasunich> same brand, same size.....
[18:36:17] <jmkasunich> 451 lbs - no wonder its hard to move around
[18:45:32] <BigJohnT> * BigJohnT is off to make parts for upgrading the plasma floating head
[19:18:30] <jmkasunich> there it is: http://www.use-enco.com/CGI/INSRIT?PARTPG=INLMKD&PMPXNO=16720603&PMAKA=619-2879
[19:19:23] <jmkasunich> I paid exactly 10% of the list price ;-)
[19:19:36] <jmkasunich> </gloat>
[19:23:28] <archivist_ub> lucky bar steward
[19:24:41] <jmkasunich> needs a magnetic chuck still
[19:26:00] <jmkasunich> and a stand or bench to put it on
[19:26:07] <jmkasunich> and a spot in the basement
[19:26:18] <jmkasunich> the last will probably be the hardest part
[19:26:29] <mshaver> can anyone tell me if the hostmot2 files (.bit, etc.) are in 2.2.5, or only in trunk?
[19:26:41] <jmkasunich> trunk only I believe
[19:27:00] <mshaver> ok, i'll get that!
[19:27:01] <jmkasunich> I think the plan is to put them in 2.2.6 when that is released, in a week or two
[19:27:12] <mshaver> good!
[19:29:14] <mshaver> do I understand it correctly that with hostmot2, there's no need to make a separate .bit file for every configuration of step gens, pwms, etc? That these can all be selected and mapped to 5i20 pins at runtime?
[19:29:54] <jmkasunich> I believe its something like that
[19:30:02] <mshaver> ok
[19:30:12] <mshaver> I can only hope...
[19:30:27] <jmkasunich> there are some limits - for example, I don't think the pin mapping is arbitrary
[19:30:57] <jmkasunich> a certain pair of pins can be step or pwm, but if you choose step, the now unused pwm generator can't be reused on other pins
[19:31:34] <mshaver> but hopefully it's flexible enough to allow mapping them to 7i34 and 7i37 boards
[19:31:40] <mshaver> that will work for me
[19:31:49] <jmkasunich> I assume the pin assignments were made with those boards in mind
[19:32:12] <mshaver> i only need 2 or 4 step gens, 1 pwm, a couple of encoders and the rest gen i/o
[19:32:25] <jmkasunich> should be a piece of cake
[19:32:40] <mshaver> i hope... ;)
[19:48:56] <jmkasunich> anybody have experience running a surface grinder? I'm gonna be building a bench, and I'm wondering what is a good height
[19:49:51] <jmkasunich> for lathes, the rule of thumb is spindle centerline about elbow high
[19:50:05] <jmkasunich> wondering if there is something similar for grinders
[20:00:34] <mshaver> the B&S #2 grinder I have at home is one piece, floor to spindle. the top of the chuck is fairly high (I could measure it when I get home), I think the idea is that the just ground surface should be near the eye so as to be easy to see. The control height ought to be elbow height or slightly lower to make it comfortable to operate when standing straight up.
[20:01:37] <jmkasunich> good point - I was leaning toward table top at elbow height, but cranks at elbow height is probably better
[20:01:49] <jmkasunich> the one I got is a bench model, like this: http://www.use-enco.com/CGI/INSRIT?PARTPG=INLMKD&PMPXNO=16720603&PMAKA=619-2879
[20:02:24] <anonimasu> hmm, are they good?
[20:02:36] <jmkasunich> are what good?
[20:02:57] <anonimasu> the enco grinders?
[20:03:08] <jmkasunich> dunno - the one I just bought is surplus
[20:03:12] <anonimasu> ok
[20:03:21] <anonimasu> going to cnc it?
[20:03:23] <jmkasunich> made in 1990, tiawan label
[20:03:33] <jmkasunich> seems identical to the one in that photo
[20:03:44] <jmkasunich> not planning to CNC it (at least not anytime soon)
[20:04:12] <jmkasunich> I got it because the price was right (10% of the enco price ;-)
[20:04:41] <jmkasunich> single phase 120V spindle motor, no special electric needs
[20:12:34] <jmkasunich> anonimasu: you just got a grinder didn't you?
[20:12:53] <anonimasu> no, im still waiting for sweden to wake up from vacation times
[20:12:59] <anonimasu> I cant get it shipped until next week
[20:13:00] <jmkasunich> heh
[20:13:20] <anonimasu> unless I hire some freight company to do it.. and that's $$$
[20:13:20] <anonimasu> :p
[20:13:33] <jmkasunich> yours is much bigger than bench top isn't it?
[20:13:36] <anonimasu> yeah
[20:14:06] <anonimasu> it's a pretty big machine I think 900kg.. or so
[20:14:24] <jmkasunich> this one is ~200kg
[20:14:40] <jmkasunich> what work size? this one is 300mm x 150mm
[20:15:15] <anonimasu> I have no idea
[20:15:20] <anonimasu> 900x400 or something
[20:15:22] <anonimasu> I think
[20:15:23] <anonimasu> mm that is
[20:16:25] <jmkasunich> that is big
[20:16:36] <jmkasunich> 36 x 16"
[20:16:39] <jmkasunich> huge even
[20:16:51] <jmkasunich> that is a lot more than 900kg I bet
[20:17:53] <anonimasu> dunno.. a ton or so
[20:17:53] <anonimasu> :)
[20:17:55] <anonimasu> I think
[20:17:59] <jmkasunich> heh - here is a 900x400
[20:18:00] <jmkasunich> http://www.machinestock.com/site/msdatasheet.php?machineno=1065-2710&lang=uk
[20:18:08] <jmkasunich> it weighs 4.2t
[20:19:40] <anonimasu> I cant remember the exact size though it was pretty big..
[20:19:50] <jmkasunich> do you have maker name or model?
[20:20:32] <anonimasu> PODHAJSKY
[20:21:36] <jmkasunich> heh, the only mention of that name google could find was you
[20:22:04] <jmkasunich> you posted this pic:
[20:22:05] <jmkasunich>
[20:22:09] <jmkasunich> that is not 900x400
[20:22:19] <anonimasu> I cant remember the travel.
[20:22:30] <anonimasu> I found a desc of it .. it might be alot less. :p
[20:22:49] <jmkasunich> the travel seems to be about 3.5x the wheel diameter
[20:22:56] <jmkasunich> I'm guessing the wheel is 200mm max
[20:23:08] <anonimasu> * anonimasu has big issues remembering numbers accurately
[20:23:08] <anonimasu> :/
[20:23:21] <jmkasunich> I hope you have a strong forklift
[20:23:40] <jmkasunich> grinders are very heavy for their size
[20:23:48] <anonimasu> got a tractor for moving snow with
[20:23:53] <anonimasu> with forks..
[20:24:14] <jmkasunich> I bet that grinder is 1500kg, maybe 2000
[20:24:23] <anonimasu> * anonimasu nods
[20:24:26] <anonimasu> nice
[20:24:32] <anonimasu> I like heavy machines
[20:24:37] <jmkasunich> as long as you don't have to move them
[20:24:51] <anonimasu> yep
[20:25:49] <anonimasu> :)
[20:26:12] <jmkasunich> I was looking at a mitsui grinder at HGR - very nice quality, far better than the one I got
[20:26:14] <jmkasunich> only $900
[20:26:19] <fragalot> BigJohnT: desktop sized one,.. thinking 500x500x600 (w,l,h)
[20:26:20] <anonimasu> * anonimasu nods
[20:26:23] <jmkasunich> but sanity kicked in
[20:26:39] <anonimasu> mine was very cheap.. though I'll end up paying more for shipping :)
[20:26:51] <anonimasu> it's got a huydralic problem with the feed..
[20:26:59] <anonimasu> I like that alot
[20:27:12] <jmkasunich> problems = low prices
[20:27:19] <anonimasu> yep
[20:27:20] <fragalot> BigJohnT: doubt the holding torque has any importance, as it 'l be a worm-type thing
[20:27:22] <jmkasunich> the trick is finding machines with problems that we can fix cheaply
[20:27:30] <fragalot> jmkasunich: I love quicktech for that
[20:27:40] <jmkasunich> quicktech?
[20:27:42] <fragalot> the machines are cheap, replacement parts are cheap (and can often be pulled out of normal computer sxD)
[20:27:44] <anonimasu> huydralic cant be alot of different things(we do lots of hudyralics at work)
[20:27:57] <anonimasu> huydralic..
[20:27:57] <anonimasu> :p
[20:28:04] <jmkasunich> hydraulic
[20:28:05] <fragalot> jmkasunich: http://www.quick-tech.com.my/cncmachine.html taiwanese, but great service & good machines
[20:28:49] <jmkasunich> fragalot: a bit out of my class
[20:28:50] <fragalot> jmkasunich: there are 6 of those quicktech machines running out of 9, (the other 3 are Daewoo lathes, which SUCK if something breaks... stupid FUNIC or whatever it is called)
[20:29:15] <fragalot> jmkasunich: ah, thought you were looking at 'big' stuff.. sorry, didn't read up :p

[20:29:50] <jmkasunich> I was talking to anonimasu about his big grinder
[20:30:08] <fragalot> *nod* been since highschool that i've used one :p
[20:30:10] <jmkasunich> I don't have a heated ground level shop, so I can't really have any machines I can't get into the basement
[20:30:23] <anonimasu> im looking forward to getting it and making it work
[20:30:45] <jmkasunich> right now I'm procrastinating, because I need to clear a spot in the basement for the machine
[20:30:48] <jmkasunich> I hate cleaning
[20:30:59] <anonimasu> * anonimasu nods
[20:31:06] <BigJohnT> fragalot: I was over by the mill making parts
[20:32:00] <anonimasu> :)
[20:32:15] <jmkasunich> even this little grinder needs a 48" wide space
[20:32:24] <dmess> well ive ordered my 3 motors, and 3 axis controller and 2 I/O modules for 2 outputs each...
[20:32:56] <dmess> now to make a manual hardinge WORK and make $$ in the dark...
[20:33:13] <anonimasu> :p
[20:33:21] <anonimasu> * anonimasu nods
[20:33:36] <anonimasu> I'd like a cnc lathe and design a bar feeder..
[20:33:48] <fragalot> hehe
[20:34:00] <fragalot> I'd like to make me a working desktop sized mill
[20:34:19] <fragalot> how much do you guess i'd have to spend on that, rough estimate
[20:34:36] <anonimasu> more then buying a used one would cost
[20:34:49] <archivist_ub> visit the scrap yard as I did, with a bit of scrounging as well
[20:34:49] <anonimasu> unless you have access to machines yourself
[20:35:10] <dmess> i have 2 cross slides to work with.... i got http://cgi.ebay.ca/ws/eBayISAPI.dll?ViewItem&ssPageName=STRK:MEWNX:IT&item=330254039921
[20:35:19] <fragalot> anonimasu: I have access to machines
[20:35:37] <fragalot> I just want something small to use at home :)
[20:35:40] <archivist_ub> then you can make connecting pieces
[20:36:08] <anonimasu> :)
[20:36:08] <dmess> i do too.. no problem for THIS goverment job... OR i could do it myself too
[20:36:33] <fragalot> right now i'm aiming for ~$200 or so?
[20:37:28] <dmess> this is the SWEETEST lathe head and accessory package available... i dont have them all but i WISH i did
[20:37:39] <fragalot> hehe
[20:37:48] <fragalot> used lathe chucks scare me
[20:38:09] <fragalot> a few years back, a big 35kg one worked itself free and took a chip out of my ear
[20:38:16] <dmess> i can get you a 110V the same as mine for 600 canadian
[20:38:40] <archivist_ub> pc is cheap to free, motor dirves can be made but I bought new at £25 ea 4 axis, steppers I bought 3 atv £30 and use an old free one, scrap ally about40, XY from a £20 machine, Z from a Lathe and the rest scrounged
[20:38:41] <fragalot> d110V, then i'd need to get a transformer too... :p 240 here
[20:38:59] <dmess> this is 230- 150 kg.. me and my son will attest to that
[20:39:07] <fragalot> dmess: haha :p
[20:39:23] <archivist_ub> * archivist_ub off to shops
[20:39:41] <dmess> woell hell i can sind it with MY motor and scab that one...
[20:41:09] <dmess> I still need a vfd or a 110v motor to run mine... i could do the rebuild within the next 2 weeks if your into it
[20:41:14] <acemi_> acemi_ is now known as acemi
[20:42:35] <dmess> mototr is currently OFF mine... i was supposed to go buy the other 1 TODAY... and it isnt over....where are you located??
[20:43:04] <fragalot> who?
[20:43:12] <dmess> you
[20:43:19] <fragalot> belgium...
[20:43:34] <fragalot> just a wee bit too far :p
[20:44:28] <dmess> 500-750 bucks canadian in shipping... your call...
[20:44:49] <fragalot> above my price range
[20:45:06] <fragalot> esp. since i still need to pay for a new washing machine out off my student pay >.>
[20:47:22] <dmess> but this IS a 2000 dollar headstock
[20:47:53] <fragalot> which is WAY above my price range :p
[20:48:16] <fragalot> basically all i'd use this lil' mill for is to make PCB's, and just.. goofing arround with it
[20:48:33] <fragalot> for the big stuff i can just go to my summer job and do it on the big machines
[20:49:08] <dmess> how big do you call big son
[20:50:05] <fragalot> 1270mmx600mm table
[20:50:22] <dmess> wel wait for my 'lil guy JUST for that..
[20:50:41] <fragalot> :p
[20:51:48] <dmess> thats a SMALL machine for me.... i've worked 8M x 6M x 3+M
[20:52:38] <fragalot> for ME that is bigger than I need :p
[20:52:49] <dmess> with rotary and head changers.. all the comforts of a cadillac
[20:54:20] <dmess> its hard to make SMALL parts on a BIG machine.... but bigger parts have been made on a small machine before....
[20:54:32] <fragalot> 5-axle one with 24 tool changer
[20:54:39] <fragalot> dmess: exactly
[20:54:51] <fragalot> last time we had to do 3 meter long profiles,... just opened up the side windows :p
[20:55:40] <dmess> were you NEEDing to holad it with a crane?? been there got that scare
[20:55:59] <dmess> and scar
[20:56:23] <fragalot> it's a small shop,.. the forklift just fits
[20:56:35] <fragalot> and the machines have a 2mm clearance to the ceiling
[20:57:14] <fragalot> so, if you are working on it and forget a screwdriver ontop of it,.. Z moves up,.. *pop* hole in the ceiling :p
[20:57:46] <dmess> we got walls going up in the shop.. to make the 787 gear fit.. and the f/lifts refuse to use certian ieles..
[20:58:06] <fragalot> got that same problem
[20:58:08] <anonimasu> hm..
[20:58:21] <fragalot> the previous owner cheaped out on the fundations of the building, so one half is just inaccessible for the forklift
[20:58:58] <fragalot> (the tiles tend to drop ~10cm if you go over them with a forklift)
[20:59:13] <anonimasu> wow
[20:59:24] <dmess> we just shippe a superjet 100 MLG shipset with a check on EACH leg for 220,000 canidian
[20:59:38] <fragalot> :/
[21:00:36] <dmess> and now apperantly the new Bombarier c -series is a mus WIN
[21:00:46] <dmess> must
[22:04:35] <dmess> so would a laptop do my system any justice.. 2-3 axis lathe at best
[22:19:25] <jmkasunich> dmess: many laptops have issues with realtime
[22:30:57] <skunkworks> sort of the luck of the draw
[23:30:02] <skunkworks> fenn: I did't know if you saw this.. http://www.cnczone.com/forums/showthread.php?t=60818
[23:36:10] <skunkworks> I think this will be the test circut.. http://www.electronicsam.com/images/KandT/servostart/Newschem3.png
[23:36:23] <skunkworks> (yes I am still using an op-amp...
[23:36:25] <skunkworks> )
[23:36:34] <jmkasunich> shame on you!
[23:37:06] <skunkworks> well - I can't blame you if it doesn't work.. ;)
[23:37:14] <jmkasunich> right!
[23:37:32] <jmkasunich> do you already have some TL082's or something?
[23:37:57] <skunkworks> yes
[23:38:07] <jmkasunich> ah, that explains it
[23:38:21] <skunkworks> for some reason I had them from a previous audio amp experiement.
[23:39:34] <skunkworks> it was my first experience with thermal run-away.
[23:39:35] <skunkworks> ;)
[23:40:29] <skunkworks> I was using some big-ass darlington power transisters for the final stage.. 'as long as I kept them cool...'
[23:41:12] <jmkasunich> heh
[23:41:26] <jmkasunich> I wish I could find things around here
[23:41:54] <jmkasunich> somewhere I have a medium sized cleat (like you use to dock a boat)
[23:42:28] <jmkasunich> in the past I've screwed it to the floor above the head of the stairs, to anchor a block and tackle for lowering stuff down the steps
[23:42:48] <skunkworks> it is probably where you last put it...
[23:43:00] <jmkasunich> yeah, but where was that?
[23:43:03] <skunkworks> ;)
[23:43:25] <jmkasunich> I should just permanently bolt it to the floor
[23:43:35] <skunkworks> biab..
[23:43:35] <jmkasunich> nautical theme decor you know
[23:43:50] <skunkworks> in case the house rolls?
[23:44:19] <jmkasunich> floats away
[23:58:24] <DaViruz> is it neccesary to use linux 2.6.10 as described in RtaiSteps in the wiki, or could i use, say, 2.6.20?
