[07:04:51] <jthornton> dang I slept in
[07:08:41] <Loetmichel> jthornton: its sunday, so what? ;-)
[10:50:41] <MattyMatt> but he's the vicar
[10:51:02] <MattyMatt> (slow joke for slow day)
[11:15:08] <CaptHindsight> random punchlines?
[11:20:19] <Loetmichel> CaptHindsight: no, just 6 hrs delay ;-)
[11:20:23] <Loetmichel> 5
[11:22:12] <Loetmichel> [13:48] <jthornton> dang I slept in
[11:22:12] <Loetmichel> [13:52] <Loetmichel> jthornton: its sunday, so what? ;-)
[11:22:17] <Loetmichel> [17:34] <MattyMatt> but he's the vicar
[11:22:17] <Loetmichel> [17:34] <MattyMatt> (slow joke for slow day)
[12:27:55] <IchGuckLive> hi all B)
[12:28:55] <IchGuckLive> Loetmichel: what a day in the sun
[12:30:20] <Tom_itx> g'day
[13:03:07] <IchGuckLive> printallthething: that is the future!!
[13:03:50] <IchGuckLive> im off HAVE a nice Sunday where ever you are !!! ;-)
[13:34:40] <Jentrep> Any good books on CNC control architectures? :)
[13:47:13] <archivist> Jentrep, not found any yet
[13:47:25] <Jentrep> :9
[13:47:26] <Jentrep> *:(
[13:48:26] <archivist> what are you looking for though as there is plenty knocking about in reports and other similar docs
[14:34:19] <someone972> I just measured the backlash on my homebuilt machine and it appears to be 1/1000th of an inch
[14:35:48] <someone972> I'm quite happy with that, plus increments of 0.0005 inch should be plenty precise for what I'll be using it for (pcb milling and such)
[14:36:07] <JT-Shop> can you run two rotary phase converters to feed the same 3 phase buss?
[14:46:25] <archivist> that sounds a little desperate
[14:47:23] <archivist> you need to adjust the phase between the two else you will have enormous recirculating current
[14:56:25] <Jymmm> http://www.wimp.com/bestseconds/
[14:57:55] <JT-Shop> trying to reduce voltage drop when the 308 spindle kicks in
[14:58:25] <JT-Shop> I've been twiddling with it this morning and have it working up to 3k without tripping
[14:58:38] <JT-Shop> http://imagebin.org/286352
[15:00:35] <JT-Shop> http://pe.org.pl/articles/2013/3a/38.pdf
[15:05:09] <JT-Shop> anyway the 308 is running 2000% better than yesterday
[15:10:06] <archivist> that article has the converters driven in phase so they cannot get out, your rotary is different
[15:10:33] <JT-Shop> yea, I thought it might be a bad idea
[15:12:00] <archivist> dunno how you would bring them into phase before throwing the switch
[15:12:43] <JT-Shop> I used to run power generators on offshore rigs and we had to dial in the phase before adding a generator to the line
[15:13:06] <JT-Shop> we had a balance meter between the generators of some sort
[15:13:10] <archivist> my generator has lamps which you slow/speed the machine till they go out
[15:38:19] <archivist> spindle encoder wheel nearly cut for the 5 axis
[16:00:14] <Tom_itx> once they lock phase do they tend to stay there?
[16:22:31] <archivist> you have to adjust them to generate rather than be driven
[16:35:51] <Deejay> gn8
[20:32:05] <owhite> hello people. I'm running a mesa 5i20 card to drive steppers, and I was using pncconf to try to create configuration files for the mesa card, but it seems like it's mostly for setting up servos, not steppers.
[20:32:40] <owhite> am i misinterpreting the use of pncconf?
[20:33:16] <atom1> i honestly have never used it
[20:33:35] <atom1> you need to find a bit file for the card that uses steppers instead of servos
[20:33:53] <atom1> unless it's designed for servos
[20:34:16] <owhite> so the bit file is generated by pncconf or something else?
[20:34:23] <atom1> no
[20:34:40] <atom1> you can find them at mesanet.com under your board name
[20:35:33] <owhite> oh cool I'll look around. Thanks much.
[20:35:45] <atom1> looks like initially it's set up for servos
[20:37:41] <atom1> do you have a daughter card for it?
[20:38:36] <owhite> no I thought I could connect the 5i20 to my gecko 320s.
[20:39:20] <atom1> those are servo drives
[20:40:06] <owhite> yeah they drive servos but they only take stepper input. The 320s handle reading the encoders and driving the motors with step/dir input.
[20:40:36] <atom1> still should use a servo bit file
[20:40:59] <atom1> http://www.geckodrive.com/g320.html
[20:41:48] <atom1> pcw_home could verify that
[20:42:04] <owhite> what's pcw_hom?
[20:42:25] <owhite> oh, a irc user.
[20:42:27] <atom1> he's here
[20:42:28] <owhite> sorry.
[20:42:32] <atom1> sometimes
[20:43:02] <atom1> so i'm doubting you can use those drivers with steppers
[20:43:37] <pcw_home> the 320s are step/dir drives so you need a step/dir FPGA config
[20:43:53] <owhite> yep.
[20:44:01] <atom1> but they still won't work with steppers will they?
[20:44:07] <pcw_home> (and 320s are DC brush motor drives)
[20:44:29] <owhite> yes, the 320 drive brushed servos.
[20:44:57] <atom1> you said you wanted to drive steppers
[20:45:11] <pcw_home> so you just need a suitable configuration file
[20:45:40] <owhite> atom1: I'm sorry I must have said something that was confusing. I am ultimately driving servos.
[20:45:47] <atom1> ok
[20:45:51] <owhite> But with the g320s I just need step/dir.
[20:46:25] <owhite> pcw_home: would I use the on board stepgen functions on the 5i20, or not?
[20:46:26] <atom1> well pcw can probably help you find the right file
[20:46:51] <owhite> that'd be great.
[20:47:44] <owhite> pcw_home: this discussion started because I was wondering if I should use pncconf to create my configuration files. but it generates files for _servos_, not steppers.
[21:00:22] <atom1> i believe you want to use the pwmgen functions for driving your drivers
[21:00:49] <atom1> there are 4 types if you read the hostmot2 docs
[21:01:39] <atom1> 1) is pwm on Out0 and direction on Out1 which i think is what you want
[21:02:30] <owhite> got it. thanks.
[21:05:05] <Jeebiss> Hello! I am hoping to get some insight on making a RaspberryPi based CNC machine.
[21:05:38] <Jeebiss> From what I have read, the Pi by itself will not suffice, and I'll need to offload some of the work to a seperate microcontroller.
[21:05:54] <Jeebiss> Whoops.
[21:06:07] <Jeebiss> Has anyone ever tried such a set up?
[21:06:41] <Tom_itx> some have done it on a beaglebone
[21:08:32] <Jeebiss> I dont know the specifics of how the actual CNC software works, so I am not sure what part would need offloaded to a MC
[21:11:44] <jdh> Pi doesn't seem a useful target
[21:12:11] <owhite> gonna run. thanks people.
[21:14:44] <Jeebiss> jdh: what do you mean?
[21:15:04] <jdh> not much IO, sucky graphics.
[21:15:11] <jdh> the only thing it has going for it is price
[21:15:33] <jdh> better, why would you pick a Pi? What attributes does it have that would make you pick it?
[21:16:21] <Jeebiss> Im really just going off the fact that I already own one.
[21:16:26] <jdh> heh
[21:16:35] <jdh> do you have an x86 based computer also?
[21:16:58] <Tom_itx> chock it up to experience and find another platform :)
[21:17:00] <jdh> I'd suggest seeking another solution for your Pi to solve.
[21:17:15] <jdh> I have two of them.
[21:17:24] <Tom_itx> you didn't learn the first time?
[21:17:28] <Jeebiss> I guess my laptop could be the controller
[21:17:45] <jdh> nah, they are fine for what I want. I just don't want htem to be halfassed cnc controllers hooked up to a uC
[21:17:56] <Jeebiss> Haha
[21:17:56] <jdh> linuxcnc doesn't play nice with almost all laptops
[21:18:02] <Jeebiss> Oh
[21:18:10] <Jeebiss> Wellll, then my old desktop may be suited
[21:18:20] <jdh> much more likely
[21:18:26] <Jeebiss> I guess I have needed a reason to turn it back on
[21:18:50] <Jeebiss> Hmmm, so how would my computer interface with motor driver boards?
[21:18:59] <Jeebiss> Or would I still need to use a uC?
[21:19:18] <jdh> there is no need for a uC with linuxcnc
[21:19:34] <jdh> depends on your drivers. P-port or mesa cards or Pico, or ...
[21:19:49] <Jeebiss> I was originally looking at these
[21:19:49] <Jeebiss> http://www.pololu.com/product/2133
[21:20:00] <Jeebiss> But they are seeming increasingly irrelevant
[21:20:11] <jdh> not much power
[21:20:42] <Jeebiss> Hmmm, I have no guage for the power Ill need.
[21:21:04] <Jeebiss> My plan is to use my dremel as the rotary part, so that probably limits me to fairly slow speeds.
[21:21:13] <Tom_itx> another bad call
[21:21:21] <jdh> dremels have a lot of runout usually.
[21:21:22] <Tom_itx> dremels weren't made to be spindles
[21:21:26] <jdh> but, depending on whatyou want to do, it might work.
[21:21:53] <Jeebiss> Haha, well thats the last of my ideas to cross off the list.
[21:22:00] <jdh> nah
[21:22:01] <Jeebiss> What would make a better spindle?
[21:22:15] <jdh> depends on what you want to do
[21:22:59] <Jeebiss> Im not trying to make anything too extreme. I want to be able to cut 6mm plywood, acrylic, and stuff like that
[21:23:13] <Jeebiss> Maybe thin metals, but thats really stretching it.
[21:23:53] <jdh> there are lots of inexpensive spindles on eBay. Where are you?
[21:24:01] <Tom_itx> you don't want a high speed spindle for plastic
[21:24:10] <Tom_itx> it'll just burn it
[21:24:28] <jdh> not if you move fast
[21:24:36] <Jeebiss> Do they make variable speed spindles?
[21:24:42] <Tom_itx> sure
[21:24:46] <Jeebiss> jdh: im in Ohio, USA
[21:25:14] <jdh> lots of variable speed spindles on ebay
[21:25:15] <pcw_home> owhite: yes you use the stepgen function for G320s
[21:25:25] <jdh> or keling
[21:25:41] <Jeebiss> jdh: what do you consider a "inexpensive"?
[21:26:41] <jdh> http://www.ebay.com/itm/221268429297
[21:26:49] <Tom_itx> pcw_home stepgen or pwmgen?
[21:26:50] <jdh> not an endorsement, just the first one I saw
[21:27:23] <Jeebiss> Oh wow, thats more that I was thinking "inexpensive" meant haha
[21:28:02] <Jeebiss> I was hoping to spend roughly 150-200 on m entire project x_x
[21:28:20] <Tom_itx> good luck
[21:28:31] <Jeebiss> Well, thats where the existing dremel and pi came in
[21:28:48] <Jeebiss> Im seeing this may be getting more and more expensive at each step, if done correctly
[21:28:57] <jdh> sure
[21:29:13] <Jeebiss> So my next though, is it worth building the rig and using my dremel, and later upgradin to a proper spindle?
[21:29:37] <jdh> on the bright side, if you spend all your money playing with cnc toys, you won't have to waste money on females or social activities.
[21:29:38] <archivist> dremel has a rather loose bearings
[21:30:08] <jdh> Dremel would be fine to play with. I wouldn't get too attached to it.
[21:30:48] <Jeebiss> jdh: Is changing it out later on a pratical plan?
[21:31:00] <jdh> it's a good thought
[21:31:25] <jdh> and changing out the motors, drivers, bearings, screws,etc.
[21:31:27] <Jeebiss> So for the sake of cost cutting, for now ill use my dremel to play with, and upgrade later on, liiiike after taxes come back haha
[21:31:58] <jdh> http://www.artichoke.org/router.jpg
[21:32:05] <jdh> that was my first CNC cutting
[21:32:31] <Jeebiss> Looks like a dremel!
[21:34:12] <Jeebiss> Well for the sake of being thorough, should I also throw out my plan of using heavy duty drawer slides as the axies
[21:34:42] <jdh> whatever works for you
[21:34:49] <zeeshan> jdh nice
[21:35:06] <zeeshan> is that just a regular thrreaded lead screw
[21:35:16] <jdh> yeah, plain acme screw
[21:35:25] <zeeshan> oh its acme
[21:35:29] <zeeshan> not 60 deg
[21:35:35] <zeeshan> :)
[21:35:46] <Jeebiss> I was hoping to get the majority of my components at the hardware store
[21:35:55] <jdh> go for it
[21:36:04] <jdh> if it sucks, it's not a big deal.
[21:36:32] <Jeebiss> other then wasted money
[21:36:47] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/null_zps16ba25c6.jpg
[21:36:55] <zeeshan> im in the process of converting my lathe to cnc
[21:36:55] <zeeshan> :D
[21:37:07] <zeeshan> ive been looking everywhere for a decently priced set of ballscrews
[21:37:18] <zeeshan> with end supports
[21:37:30] <zeeshan> at least a 1.25" diameter ballscrew
[21:37:34] <jdh> what lathe?
[21:37:42] <zeeshan> a chinese one :P
[21:37:52] <jdh> I'm in the process of converting my chinese 9x20
[21:38:03] <zeeshan> i cant find a pic of it quickly
[21:38:05] <zeeshan> but its this one:
[21:38:09] <zeeshan> http://www.busybeetools.com/products/LATHE-12IN.-X-36IN.-2HP-GEAR-HEAD.html
[21:38:11] <zeeshan> that i bought used
[21:38:21] <jdh> cool
[21:38:31] <zeeshan> whiuch one is yours?
[21:39:14] <jdh> jet 9x20
[21:39:44] <zeeshan> oh!
[21:39:47] <zeeshan> thats a nice lathe
[21:39:54] <Jeebiss> This is going to be more of a project then I originally intended it seems.
[21:40:01] <jdh> I could probablyfigure out how to do the X axis on a 12x
[21:40:05] <zeeshan> jdh are you running steppers?
[21:40:19] <zeeshan> so far ive got 2x 1200oz steppers
[21:40:25] <zeeshan> and then an index/tachometer for the spindle
[21:40:28] <zeeshan> so i can thread
[21:41:02] <jdh> that's a lot of stepper
[21:41:20] <jdh> I think I got 482oz for the Z, something smaller for X
[21:41:51] <jdh> no room for a ballnut in a 9x crossslide so I'll have to stick on the side
[21:42:14] <archivist> encoder on my lathe spindle http://www.collection.archivist.info/archive/DJCPD/PD/2013/2013_08_04_starturn_encoder/IMG_1631.JPG
[21:42:46] <jdh> mine will look simlar to that
[21:43:17] <zeeshan> i wanted to go overkill
[21:43:27] <zeeshan> so i can really run high ipm without skipped stepps
[21:43:30] <zeeshan> i like your triggle wheel!
[21:43:33] <Tom_itx> seems you did
[21:43:56] <zeeshan> jdh i have the exact same problem.
[21:43:59] <jdh> https://picasaweb.google.com/112430417093824344570/9x20#5947064813899265538
[21:44:01] <zeeshan> most people end up putting the ball screw on the side.
[21:44:10] <zeeshan> i might make room for it
[21:44:15] <jdh> my encoder wheel... haven't mounted it yet.
[21:44:34] <Tom_itx> archivist, turned out nice
[21:44:36] <zeeshan> i have no electronics on mine
[21:44:36] <jdh> teh cross-slide could be an inch taller with room for the ballscrew, but I don't think I can make one.
[21:44:53] <zeeshan> why not?
[21:44:55] <zeeshan> do you have a mill?
[21:45:11] <jdh> zeeshan: ball screw on headstock side?
[21:45:15] <archivist> Tom_itx, that is original factory fitted, but easy to copy
[21:45:16] <jdh> I have a small mill
[21:45:25] <zeeshan> no ballscrew for x-axis
[21:45:30] <zeeshan> for the cross slide
[21:45:42] <Tom_itx> archivist, not the wheel you were cutting?
[21:45:43] <jdh> Z ballscrew was cheap and easy
[21:45:57] <jdh> I have an X one also, but I just can't bring myself to bolt it on the side.
[21:46:00] <zeeshan> did you use premade end supports
[21:46:05] <zeeshan> that you just mounted onto your lathe?
[21:46:06] <archivist> Tom_itx, no I am making a copy of that for the mill
[21:46:39] <Tom_itx> ahh i see
[21:46:42] <jdh> zeeshan: yeah, I made plates that mounted to the existing holes and mounted the screw ends to that
[21:47:03] <zeeshan> question for you
[21:47:08] <zeeshan> your tacho/index wheel
[21:47:19] <zeeshan> are you using an optical based sensor?
[21:47:21] <zeeshan> or mag
[21:47:38] <archivist> you can see two slotted optos on there
[21:47:46] <jdh> I'm using optical for AB and mag for index
[21:47:49] <zeeshan> sorry im looking at the copper wheel
[21:47:51] <Tom_itx> yeah
[21:47:55] <zeeshan> on the google photos
[21:48:02] <zeeshan> whos trigger wheel is that? :D
[21:48:10] <jdh> that's mine
[21:48:18] <zeeshan> http://www.cnc4pc.com/Store/osc/product_info.php?cPath=25&products_id=129
[21:48:24] <zeeshan> im using that kit for my tacho
[21:48:33] <zeeshan> see what i don't understand is why do you guys use a billion slots
[21:48:42] <zeeshan> why not just 1 slot
[21:48:55] <jdh> more is better
[21:48:57] <zeeshan> it just needs to pick one pulse up to syncronize for threading
[21:49:08] <archivist> 1 slot has to guess for the rest of that rev
[21:49:27] <zeeshan> my problem is if i make a trigger wheel myself
[21:49:39] <zeeshan> and i dont put the slots in the correct position
[21:49:45] <archivist> you will get drunk threads is the spindle slows due to cutting load
[21:49:45] <zeeshan> that'll bring in some dirty error :(
[21:49:58] <zeeshan> i'd have to get it cut on the waterjet
[21:50:16] <zeeshan> or if i can get away with 4 equally spaced slots i can do that within 1 thou on the mill
[21:50:26] <zeeshan> or you guys can sell me one of yours :)
[21:50:43] <jdh> 1 thou is way more than enough
[21:51:01] <jdh> print it, center punch, drill press
[21:51:16] <zeeshan> id use the dro
[21:52:36] <zeeshan> jdh your lathe looks very similar to mine
[21:52:47] <zeeshan> i like how you've mounted the z axis ballnut to the carriage
[21:52:53] <zeeshan> i might copy your design.
[21:52:54] <zeeshan> :)
[21:53:02] <jdh> I copied someone elses
[21:53:07] <zeeshan> copy of a copy.
[21:53:18] <jdh> mine is currently all bolt on to existing holes
[21:53:19] <zeeshan> how are you planning to cover your ball screw?
[21:53:35] <jdh> there is a slot cut out for an aluminum cover
[21:53:49] <zeeshan> one of those fancy telescoping style covers?
[21:53:49] <jdh> just the top though
[21:54:05] <jdh> nah, just a strip of aluminum
[21:54:24] <zeeshan> that ball screw of yours looks like a 1.25" diameter one
[21:54:26] <zeeshan> is it?
[21:54:34] <jdh> 25mm
[21:54:38] <zeeshan> fak
[21:55:05] <jdh> $100ish machined, supports, bearings, ballnut
[21:55:14] <zeeshan> linearmotion on ebay?
[21:55:17] <zeeshan> https://lh5.googleusercontent.com/-Pc1L4NlwY6E/Uf3Fi_HJwgI/AAAAAAAACWM/fp-TmcUaQnM/w672-h896-no/20130803_224817_Tall+Pine+Ct.jpg
[21:55:20] <jdh> yeah
[21:55:27] <zeeshan> looks like you got rid of your quick change gear box
[21:55:32] <zeeshan> and used the pre-existing holes?
[21:55:35] <jdh> no need for it
[21:55:37] <zeeshan> yes
[21:55:45] <jdh> yeah, there is another one behind the motor
[21:55:53] <zeeshan> i think thats a mart way to do it. you can trust the hole locations along with the dowels
[21:55:56] <zeeshan> to ensure 100% alignment
[21:56:01] <zeeshan> *smart
[21:56:21] <zeeshan> you kinda went overkill with the plates though lol
[21:56:31] <jdh> 1/2"
[21:56:36] <zeeshan> thats expensive stuff :P
[21:56:45] <Tom_itx> not so bad surplus
[21:56:46] <jdh> $15ish for that
[21:56:54] <zeeshan> thats pretty cheap
[21:56:56] <archivist> cheap at a scrap yard
[21:57:01] <zeeshan> i have tons of 1/2" steel plate
[21:57:18] <jdh> that's new from onlinemetals
[21:57:26] <zeeshan> you actually ordered from that plate?
[21:57:28] <zeeshan> *place
[21:57:28] <zeeshan> haha
[21:57:33] <zeeshan> they're expensive!
[21:57:36] <jdh> either them or onlinemetals
[21:57:55] <zeeshan> am i retarded
[21:58:02] <zeeshan> i can't see your end supports for the ball screws
[21:58:08] <jdh> yeah, no pics
[21:58:13] <zeeshan> :(
[21:58:14] <jdh> not even the cut-out in that pic
[21:59:07] <jdh> I acutally bought that plate for another project but didn't use it
[21:59:18] <zeeshan> are you keeping all your handles to move the carriage/cross slide
[22:00:39] <zeeshan> yesterday i scored the biggest deal ever
[22:00:47] <zeeshan> i picked up a 3hp 3phase weg motor for 60$
[22:00:59] <zeeshan> thing is brand new. and costs 650
[22:01:02] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/null_zps7d8376e1.jpg
[22:01:08] <jdh> I have them. I had teh Z screw made to stick off the end and machined for a handle.
[22:01:50] <zeeshan> im going to throw that along with an eaton mvx vfd and a 0-10v step/dir board to get linuxcnc to control the speed
[22:02:01] <jdh> that's a lot of motor
[22:02:10] <zeeshan> i need it
[22:02:22] <zeeshan> with the 2hp motor and drilling 2" holes the machine starts bogging down
[22:02:49] <jdh> https://picasaweb.google.com/112430417093824344570/9x20#5968220668391937810
[22:03:04] <zeeshan> thank you
[22:03:19] <zeeshan> left side is the free end
[22:03:20] <zeeshan> or fixed
[22:03:35] <zeeshan> nm
[22:03:36] <jdh> fixed, with pulley
[22:04:13] <zeeshan> this might sound silly
[22:04:20] <Jentrep> Hey people are on :)
[22:04:33] <zeeshan> but i notice that you drilled holes into the aluminum plates you made to locate your end supports
[22:04:56] <Jentrep> axis - one of the nine degrees of freedom, x, y, z, a, b, c, u, v, w these refer to axes in Cartesian space, which may or may not match up with joints (see below). On Cartesian machines they do match up, but for hexapods, robots, and other non-Cartesian machines they don't.
[22:04:57] <zeeshan> the distances of the holes apart along the axis of the ball screw
[22:05:08] <Jentrep> Is that definition correct? :/
[22:05:12] <zeeshan> did that distance have to be accurate?
[22:05:52] <zeeshan> or is 10-15 thou acceptable since the free end will just displace
[22:06:29] <Jentrep> how are the 9-axis part of a cartesian coordiante system? >_>
[22:06:55] <jdh> the spacing along the Z is not critical
[22:08:34] <jdh> I mounted a dial indicator on the cross-slide and aligned the rest to minimize error. A 1m long chinese ballscrew is not so straight
[22:08:54] <skunkworks> Jentrep: yes.. What is your real question?
[22:09:01] <zeeshan> hehe
[22:09:13] <Jentrep> skunkworks: so a 9-dimensional space? >_>
[22:09:37] <Jentrep> Why 9-axis? D:
[22:10:09] <Jentrep> its's not (x, y, z, a , b, c, u, v, w)
[22:10:28] <skunkworks> Jentrep: you can do pretty much whatever you want - but conventional setup is xyz are obvious - abc are rotational axis around xyz. uvw are usually setup as axis in the tool direction.
[22:10:30] <Jentrep> it's {(x, y, z), (a, b, c), (u, v, w)}
[22:10:43] <skunkworks> *Along the tool direction
[22:10:53] <Jentrep> axis in the tool direction?
[22:11:15] <zeeshan> think about a robot arm
[22:11:26] <zeeshan> the end effector can move in the u v w
[22:11:29] <jdh> is this a question or pedantism?
[22:12:10] <Jentrep> i am a noob :P
[22:12:12] <Jentrep> Sorry D:
[22:12:18] <zeeshan> jdh do you have a mill?
[22:12:36] <Jentrep> So in terms of a: Gyro + Accelerometer + Compass
[22:12:56] <Jentrep> We assign each sensor a 3-axis parameter?
[22:13:23] <jdh> zeeshan: http://tinyurl.com/ock5kpa
[22:13:38] <zeeshan> pretty :D
[22:13:55] <zeeshan> they make cnc kits for that mill
[22:13:58] <zeeshan> looks like g0704
[22:14:05] <Jentrep> what the hell is that?
[22:14:10] <jdh> yeah, I just made Hoss-parts
[22:14:43] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/null_zps1f93328f.jpg
[22:14:44] <zeeshan> thats my baby
[22:14:57] <zeeshan> while im shopping for ball screws for the lathe
[22:15:12] <zeeshan> i've been looking at retrofit ball screws for this mill -- almost impossible to find.
[22:15:18] <syyl--> looks like a bridgeport with a tumor on its head ;)
[22:15:23] <zeeshan> haha
[22:15:28] <zeeshan> thats the vfd enclosure
[22:15:34] <zeeshan> didn't know where else to put it
[22:15:51] <jdh> on the wall
[22:15:54] <zeeshan> i picked up this mil for literally 700$.
[22:16:02] <zeeshan> jdh: what if i move? :D
[22:16:09] <syyl--> thats a good price, theres nothing to it..
[22:16:17] <jdh> I don't have space for that.
[22:16:18] <zeeshan> i spent more on the vfd
[22:16:34] <Jentrep> Why are you guys so obsessed with milling? :o
[22:16:40] <zeeshan> Jentrep: CAUSE ITS AWESOME!!!
[22:16:52] <zeeshan> and this is the first channel where i can talk to others with similar tastes
[22:16:57] * zeeshan is a happy camper right now.
[22:17:17] <jdh> I have that bandsaw, kind of.
[22:17:19] * Jentrep just like robotic arms :3
[22:17:22] <zeeshan> most of my friends are into cars and could care less about machining
[22:17:23] <Jentrep> *likes
[22:17:35] <zeeshan> Jentrep: i used to program fanuc / abb robotic arms
[22:17:43] <zeeshan> they were fun
[22:17:45] <Jentrep> zeeshan: tell me EVERYTHING! O_O
[22:17:51] <zeeshan> you take a pendant
[22:17:53] <zeeshan> and program!
[22:17:59] <Jentrep> pendant?
[22:18:10] <zeeshan> you know, the hand controller? :P
[22:18:15] <Jeebiss> Ookay, back to noob question asking.
[22:18:17] <Jentrep> nope don't know
[22:18:36] <zeeshan> jdh: thats another project on the go
[22:18:40] <zeeshan> needs a coolant pump and speed control
[22:18:59] <Jentrep> zeeshan: you haven't told me everything yet :P
[22:19:06] <zeeshan> Jentrep: take pendant
[22:19:08] <zeeshan> sit on robot arm
[22:19:17] <zeeshan> set to cartesian mode,
[22:19:23] <zeeshan> move +z
[22:19:28] <zeeshan> done!
[22:19:39] <Jentrep> O_o
[22:20:10] <zeeshan> honestly if you really want to learn about robots
[22:20:16] <zeeshan> its kinda hard to read random shit off the internet
[22:20:19] <zeeshan> it's better just to take a course
[22:20:44] <Jentrep> well tell me! :O
[22:22:10] <zeeshan> basically abb and fanuc have their own robot programming languages
[22:22:16] <zeeshan> same with mitsubishi..
[22:22:41] <zeeshan> but the pendants are almost the same. you can move the robot in cartesian, joint, tool mode
[22:23:01] <zeeshan> you move the robot to a certain position, store the point
[22:23:07] <zeeshan> and refer to it in your program
[22:23:16] <zeeshan> thats it in a nut shell :P
[22:24:18] <zeeshan> jdh:
[22:24:19] <zeeshan> https://lh4.googleusercontent.com/-JY4oKNKKKzM/UfCOPUpGylI/AAAAAAAACQ0/y0os28H016A/w1195-h896-no/20130724_222123_Tall+Pine+Ct.jpg
[22:24:28] <zeeshan> wheres your carriage!
[22:25:15] <Jentrep> zeeshan: do those companies sell small arm dev kits? :P
[22:25:36] <zeeshan> no
[22:25:36] <Jentrep> zeeshan: and did any of those companies get bought out by Google? :(
[22:25:40] <jdh> part of it is there
[22:25:46] <zeeshan> jdh, wtf mate.
[22:25:52] <zeeshan> i didn't know i could get rid of that whole bottom piece
[22:25:56] <Jentrep> I hate Google now. :(
[22:26:08] <zeeshan> Jentrep: look at polulu or something like that
[22:26:14] <zeeshan> i think they have mini robot arms
[22:26:15] <Jentrep> Why?
[22:26:20] <Jentrep> Oh cool will do :)
[22:26:24] <Jentrep> THANKS! ^_^
[22:26:37] <roycroft> just now?
[22:26:47] <Jentrep> zeeshan: don't let Google steal you D:
[22:26:55] <roycroft> you should have started hating them as soon as they came upw with their don't be evil motto
[22:26:58] <zeeshan> google can steal me for the right price!
[22:27:04] <roycroft> because that's when they started being evil
[22:27:05] <jdh> you dont need any of that for cnc
[22:27:20] <zeeshan> jdh you've motivated me to go remove that whole section
[22:27:32] <zeeshan> https://lh3.googleusercontent.com/-eCTINXxBJz4/UfCNez3NZGI/AAAAAAAACP0/75v6CS2lPWQ/w1195-h896-no/20130724_193258_Tall+Pine+Ct.jpg
[22:27:36] <zeeshan> what were you doing in your gear box?
[22:28:06] <zeeshan> actually nm
[22:28:09] <jdh> reference pics, in case I wanted to put it back
[22:28:16] <zeeshan> that looks like the qcgb
[22:28:25] <zeeshan> mine is a lot different
[22:29:11] <zeeshan> http://i130.photobucket.com/albums/p252/turbozee84/qcgb_zpsdc44d397.jpg
[22:30:04] <Jentrep> what is that thing? ^^
[22:30:29] <zeeshan> transmission to change speeds
[22:30:36] <zeeshan> so you can make different threads on a lathe
[22:35:24] <zeeshan> well that was easy
[22:35:38] <zeeshan> 4 socket head cap screws removed and the whole thing dropped down
[22:35:41] <Jentrep> zeeshan: found this :P http://www.toolingu.com/definition-470120-81947-teach-pendant.html
[22:35:51] <zeeshan> i for some reason always thought it was a necessary part.
[22:35:57] <zeeshan> haven't taken a lathe apart before
[22:36:02] <jdh> only connected to the screw
[22:36:15] <zeeshan> yea that rack needs to be removed too
[22:36:19] <zeeshan> all useless now
[22:36:33] <zeeshan> prolly reuse that for the cnc plasma cutter hehe
[22:37:13] <zeeshan> Jentrep: too much reading :P
[22:37:18] <zeeshan> i do enough reading everyday for school
[22:37:19] <Jentrep> oh lol :p
[22:37:53] <zeeshan> by law you can't touch an industrial robot at a plant without having gone through some sort of training course :P
[22:38:08] <Jentrep> Oh I guess I better do this in another country then ;P
[22:38:10] <jdh> that's a weird law
[22:38:15] <zeeshan> nah man
[22:38:33] <zeeshan> at the plant i was working at, a person got their arm fractured by a robot
[22:38:41] <zeeshan> this robot typically moved 500lb castings
[22:38:47] <zeeshan> so it can easily own a persons arm
[22:39:00] <zeeshan> guy was working on the robot without doing proper lockout procedure
[22:39:13] <zeeshan> so i think some sort of training is necessary :P
[22:39:29] <jdh> sure, LOTO training
[22:39:35] <zeeshan> #1 rule: always keep the teach pendant on you!
[22:40:28] <Jentrep> So that's what they forgot when they built Skynet
[22:40:31] <Jentrep> :P
[22:40:36] <zeeshan> hah
[22:41:41] <Jeebiss> holy crap, the more I read about CNC machines, the less I think I am qualified to make one x_x
[22:42:02] <zeeshan> jeebis you need at least a mill to make the parts
[22:42:09] <jdh> nah
[22:42:17] <Jeebiss> i have accesss to basic shop tools, not too much more
[22:42:28] <zeeshan> i'm all about precision
[22:42:29] <zeeshan> :)
[22:42:46] <Jeebiss> id love to be, but im no machinist
[22:42:48] <zeeshan> or you can buy a g0704 mill
[22:42:53] <zeeshan> and buy the kit for it
[22:43:10] <Jeebiss> i think we are on entirely different pages hahah
[22:43:21] <jdh> I made most of the parts out of delrin for mine (on router)
[22:43:35] <jdh> then after it was working, re-made them in aluminum on themill
[22:43:38] <zeeshan> Jeebiss: i think its fundamental to learn basic manual machining before diving into cnc
[22:43:48] <zeeshan> jdh isnt delrin expensive
[22:43:57] <Jeebiss> i would agree, but i have no tools to learn the fundementals on
[22:43:57] <jdh> ebay
[22:44:14] <zeeshan> Jeebiss: community college? :D
[22:44:15] <jdh> didn't need much. Just some motor mounts, spacers, etc.
[22:44:33] <jdh> if I didn't have to work, I'd spend a lot of time at the community college.
[22:44:43] <Jentrep> zeeshan: Coursera ;P
[22:44:45] <zeeshan> jdh why not make yourself a nice chunk of machining wax
[22:44:46] <Jeebiss> zeeshan: funny you mention, i start at the local community college tommorow
[22:44:50] <zeeshan> Jeebiss: nice!
[22:44:57] <zeeshan> im doing my masters at mcmaster
[22:45:02] <zeeshan> so i have access to the machine shop there
[22:45:04] <Jeebiss> Oh wow
[22:45:06] <jdh> a mcmaster master?
[22:45:09] <Jeebiss> lol
[22:45:13] <zeeshan> not mcmaster carr hahah
[22:45:20] <Jeebiss> oooh
[22:45:29] <zeeshan> mcmaster.ca
[22:45:29] <zeeshan> :)
[22:45:44] <Jeebiss> Im hoping to knock out my gen-ed stuff, and go to a proper college for EE
[22:46:00] <jdh> I like mcmaster.com
[22:46:04] <zeeshan> me too
[22:46:17] <zeeshan> the only thing i don't like is they dont ship to canada unless you're a big business or a university
[22:46:20] <zeeshan> :(
[22:46:46] <zeeshan> most of the stuff on mcmaster, i have like a list of 50 contacts locally
[22:46:54] <zeeshan> i like in hamilton, the manufacturing/steel town!
[22:47:03] <zeeshan> they have a whole store just for o-rings and gaskets
[22:47:29] <Jeebiss> Ah, im rigth accross the lake in Cleveland
[22:47:35] <zeeshan> haha nice
[22:47:42] <zeeshan> i always wished they would make a massive bridge across.
[22:47:48] <zeeshan> or run a ferry
[22:47:53] <zeeshan> apparently in the past there was a ferry.
[22:48:00] <Jeebiss> In may I am going to be doing a bike trip to Torronto, plan on stopping in Hamilton to visit some friends.
[22:48:27] <zeeshan> Jeebiss: i hope its not downtown hamilton
[22:48:33] <zeeshan> i stay away from there.
[22:48:47] <Jeebiss> Not sure, but Ill keep that in mind lol
[22:54:26] <Jentrep> Is there still a bunch of Standard Oil stuff in Cleveland? :P
[22:57:21] <Jeebiss> Not really heh
