[00:00:03] <Connor> the X and Y adjust the electrode so to speak ?
[00:00:04] <XXCoder> curious if any of you guys ever ran a CMM
[00:00:06] <Connor> to make contact ?
[00:00:15] <tjtr33> its just like a file, big bastard then down to riflers
[00:00:30] <tjtr33> not contact, more like 'to reach'
[00:01:00] <tjtr33> yes x&y adjust the elctrode cross section ( in effect)
[00:08:35] <Tom_itx> XXCoder there were two of them at the shop i was at for a while
[00:08:45] <Tom_itx> i didn't do alot with them though
[00:09:00] <Tom_itx> one manual and one automatic
[00:09:01] <XXCoder> cool. I saw one for first time last fridat
[00:09:05] <XXCoder> it was pretty cool
[00:09:10] <Tom_itx> they are
[00:09:27] <Tom_itx> they float on air bearings
[00:09:51] <XXCoder> I guess for extreme precision
[00:09:55] <ChuangTzu> what is an edm orbiter
[00:12:33] <XXCoder> Tom_itx: onder if it can be used to find new object shape
[00:12:44] <XXCoder> or only can work with known model in solidcam?
[00:14:43] <tjtr33> ChuangTzu,
http://www.youtube.com/watch?v=a9MDKTVMQwQ
[00:17:01] <ChuangTzu> tjtr33: what does it do?
[00:17:13] <ssi> hi
[00:17:55] <tjtr33> make a tool seem larger than it really. kinda like a boring head
[00:24:33] <zeeshan> hi ssi
[00:24:38] <zeeshan> what are you upto
[00:24:39] <XXCoder> yo
[00:39:47] <ssi> zeeshan: winding down
[00:40:12] <ssi> I bought a 20t shop press and a big blast cabinet for the airport shop today
[00:40:22] <ssi> got my coolant pump housing powder coated and rebuilt with new bearings
[00:41:48] <zeeshan> nice
[00:41:57] <zeeshan> dont you have a job!
[00:42:02] <zeeshan> youre always working on your machines!
[00:42:02] <zeeshan> ;D
[00:42:40] <ssi> yeah actually I managed to keep my job
[00:42:43] <ssi> so that's a good thing
[00:42:48] <ssi> they laid off 10% of the workforce this week
[00:42:59] <zeeshan> eek
[00:43:14] <ssi> http://money.cnn.com/2014/10/06/media/turner-broadcasting-reductions/
[00:43:39] <zeeshan> you work at a news station?
[00:44:07] <ssi> it's more than a news station :P
[00:44:10] <zeeshan> o
[00:44:31] <zeeshan> if they got rid of nancy grace
[00:44:35] <zeeshan> everything would be okay
[00:44:53] <zeeshan> any progress on your cnc?
[00:45:04] <ssi> coolant pump is about it
[00:45:07] <ssi> I ordered my vfd
[00:45:11] <zeeshan> waiting on the boards?
[00:45:28] <zeeshan> i wish i could order my vfd
[00:45:30] <ssi> yeah, but worse than that
[00:45:32] <zeeshan> i found a killer deal on ebay
[00:45:37] <zeeshan> http://www.ebay.ca/itm/Sumitomo-VFD-AC-1-Phase-5-HP-Max-3-Phase-10-HP-Max-200-240-Volts-/171388500859?pt=LH_DefaultDomain_0&hash=item27e78cfb7b
[00:45:40] <ssi> I'm waiting on servo drives :(
[00:45:42] <zeeshan> sensorless vfd too
[00:45:50] <zeeshan> 345!!!
[00:45:53] <zeeshan> dirt cheap
[00:46:11] <zeeshan> why your drives are nfg?
[00:46:29] <ssi> because parker are a bunch of ridiculous assholes
[00:46:45] <zeeshan> i wonder if bosch drives
[00:46:51] <zeeshan> are easy to work with
[00:47:18] <zeeshan> these guys were trying to help me decode this:
[00:47:19] <zeeshan> http://i.imgur.com/7chGqM1.jpg
[00:47:57] <ssi> looks straightforward
[00:48:01] <ssi> DC servos
[00:48:12] <zeeshan> with a brake
[00:48:16] <zeeshan> iit looks like
[00:48:28] <ssi> ya
[00:48:36] <ssi> and tachometers
[00:48:50] <zeeshan> there seems t obe 2 switches
[00:48:52] <zeeshan> not sure what thats for
[00:48:55] <zeeshan> anf the FG
[00:49:02] <zeeshan> we wer e thinking i^2t is a temp sensor
[00:49:05] <zeeshan> *anf = and
[00:49:27] <zeeshan> are tachometers part of resolvers
[00:49:28] <zeeshan> or encoders?
[00:49:32] <zeeshan> could be either?
[00:49:55] <ssi> tachometers are what you need for velocity feedback for velocity mode drives
[00:50:06] <zeeshan> but what im asking is
[00:50:19] <zeeshan> are the tachs inside the servo through an encoder?
[00:50:24] <zeeshan> like an optical disc that rotates
[00:50:28] <zeeshan> and outputs a velocity?
[00:50:31] * zeeshan has no clue
[00:50:43] <ssi> mostly that vintage I think they're tachogenerators
[00:50:53] <ssi> they put out a voltage proportional to the speed they're spinnig
[00:50:59] <zeeshan> ah
[00:51:10] <ssi> my hnc has tachogenerators
[00:51:15] <ssi> and they get dirty and unreliable
[00:51:17] <ssi> have to be cleaned out
[00:51:20] <zeeshan> ah
[00:51:23] <zeeshan> theyre inside the servo housing?
[00:51:27] <ssi> no
[00:51:30] <ssi> on the hnc they're not
[00:51:44] <ssi> the servo is coupled to the ballscrew via a belt reduction
[00:51:48] <zeeshan> i took one of the ervos off so far
[00:51:52] <ssi> the ballscrew is coupled on the end to another belt pulley
[00:51:54] <zeeshan> its like 50lb
[00:51:57] <zeeshan> same here
[00:52:01] <ssi> or gear rather, which drives the resolver and the tachogenerator
[00:52:05] <zeeshan> it looks like a 2:1 ratio
[00:52:20] <zeeshan> oh so youre saying the resolver + tachgenerator
[00:52:29] <ssi> they're separate doohickeys
[00:52:30] <zeeshan> will be in line with the ball screw
[00:52:36] <ssi> mine aren't
[00:52:41] <ssi> they have little pinion gears
[00:52:48] <ssi> and they're held in mesh with a bigger pinion gear
[00:52:51] <ssi> in this big round assembly
[00:52:58] <ssi> then the whole round assembly is clocked on the ballscrew
[00:53:08] <ssi> and you can rotate all of the above to change the angle references
[00:53:11] <ssi> for home fine-tuning
[00:53:29] <ssi> it's fairly complex mechanically :P
[00:53:47] <zeeshan> interesting
[00:53:52] <zeeshan> my machine has scales
[00:53:56] <zeeshan> for home positioning
[00:54:09] <zeeshan> you havent seen it yet
[00:54:10] <zeeshan> but it fits!
[00:54:22] <zeeshan> http://i.imgur.com/Y042d8q.jpg
[00:55:19] <ssi> you have too much crap
[00:55:20] <ssi> the car's gotta go
[00:55:29] <zeeshan> i just move it out
[00:55:32] <zeeshan> if im doing a lotta work
[00:55:35] <zeeshan> otherwise it doesnt bother me
[00:55:44] <ssi> I don't even have to move my airplane out of t he way to use the vmc :)
[00:55:44] <XXCoder> just adjust your time lord garage to have 50x50 more feet
[00:56:27] <zeeshan> im gonna reposition the mill
[00:56:34] <zeeshan> it's back faces my brown tool box
[00:56:38] <zeeshan> it'll save me 22" of space
[00:56:57] <zeeshan> its 72" how it sits
[00:57:02] <zeeshan> vs 50" the other way
[00:57:44] <ssi> I'd leave it as is honestly
[00:57:50] <ssi> so you can fixture long parts along X
[00:58:04] <zeeshan> i do work on long shafts sometimes
[00:58:06] <zeeshan> keyways mostly
[00:58:07] <zeeshan> hm
[00:58:14] <zeeshan> okay then ill tuck it more back
[00:58:17] <XXCoder> thats whay she said
[00:58:17] <zeeshan> after the big ass control cabinet is gone
[00:58:30] <zeeshan> http://i.imgur.com/js7pUBj.jpg
[00:58:36] <zeeshan> you can see the retarded old school computer
[00:58:36] <ssi> I had to space my vmc 2' away from the wall so I had access to the control cabinet on the back, and the swarf window on the right side
[00:58:39] <zeeshan> and big ass control cabinet
[00:58:43] <zeeshan> ill move it further there
[00:59:05] <ssi> I have an 11x11' square carved out for the vmc
[00:59:06] <zeeshan> that control cabinet will be garbage in a couple weeks
[00:59:21] <zeeshan> nice
[00:59:51] <ssi> what's the spindle taper?
[00:59:52] <ssi> BT30?
[00:59:56] <zeeshan> iso40
[01:00:15] <zeeshan> it definitely has a pneumatic tool changer
[01:00:19] <zeeshan> but i dont know what it uses
[01:00:20] <zeeshan> a stud
[01:00:22] <zeeshan> or what..
[01:00:30] <ssi> where's the tool carousel?
[01:00:38] <zeeshan> it doesnt have an automatic tool changer
[01:00:41] <ssi> oh
[01:00:42] <zeeshan> i mean manual
[01:00:44] <zeeshan> but pneumatic..
[01:00:45] <ssi> just a power drawbar
[01:00:46] <zeeshan> yea
[01:00:57] <ssi> yeah it needs a power drawbar for a 40 taper spindle
[01:01:04] <ssi> I guess that's what the dunce cap has in it :)
[01:01:09] <ssi> where's the spindle motor?
[01:01:14] <zeeshan> that green thing
[01:01:16] <zeeshan> on the top back
[01:01:40] <zeeshan> i think theres a big shaft
[01:01:46] <ssi> odd
[01:01:47] <zeeshan> that runs through the entire column
[01:01:51] <zeeshan> yea
[01:01:52] <ssi> bevel gears in the spindle head
[01:01:53] <ssi> ?
[01:01:55] <zeeshan> i thinkso
[01:02:00] <zeeshan> thats the only thing that would make sense
[01:02:00] <ssi> weird
[01:02:17] <zeeshan> hey at least
[01:02:22] <zeeshan> it's got a tag saying made in switzerland
[01:02:29] <zeeshan> so it's good be good right?
[01:02:29] <zeeshan> :D
[01:02:30] <ssi> they love gears
[01:02:31] <ssi> heh
[01:02:33] <zeeshan> *gotta
[01:02:39] <ssi> it oughta keep good time at least
[01:02:40] <zeeshan> yea until one explodes
[01:03:38] <zeeshan> ha
[01:03:40] <zeeshan> going through the pics
[01:03:43] <zeeshan> found this:
[01:03:52] <zeeshan> http://i.imgur.com/wJmZCy2.jpg
[01:03:56] <ssi> is that the Y motor on the side?
[01:03:59] <zeeshan> so it uses a bosch tr10 amplifier
[01:04:01] <ssi> more damn bevel gears?
[01:04:05] <ssi> or rack and pinion, or what?
[01:04:16] <zeeshan> no
[01:04:20] <zeeshan> no rack and pinion
[01:04:30] <zeeshan> the y iis the head moving
[01:04:41] <zeeshan> theres a motor and pulley system
[01:04:43] <zeeshan> in there
[01:04:58] <zeeshan> you cant see it any of the pics
[01:05:00] <zeeshan> its kind of buried
[01:05:03] <ssi> looks like a mechanical nightmare
[01:05:13] <zeeshan> nahh
[01:05:20] <zeeshan> whats more of a nightmare
[01:05:23] <ssi> which incidentally I think is my new nickname for you
[01:05:25] <zeeshan> is figuring out where everything is going
[01:05:28] <ssi> "Zeeshan, the mechanical nightmare"
[01:05:30] <zeeshan> haha
[01:05:33] <ssi> :D
[01:06:49] <zeeshan> fuck
[01:06:57] <zeeshan> theres 3-3phase motors in this thing
[01:07:02] <zeeshan> water pump
[01:07:03] <ssi> I'm sure
[01:07:06] <zeeshan> hydraulic pump and spindle motor
[01:07:08] <ssi> mine's full the fuck up with 3 phase motors
[01:07:17] <zeeshan> the waterpump i can replace
[01:07:17] <ssi> the cooling fan on top of the spindle motor is 3 phase
[01:07:25] <zeeshan> but im really hoping the hydraulic one is a 0.5hp.
[01:07:49] <zeeshan> haha
[01:07:52] <zeeshan> how big is this fan
[01:08:29] <ssi> not really sure
[01:09:21] <zeeshan> 1hp?
[01:09:33] <zeeshan> i guess when youre running 3 phase
[01:09:36] <ssi> I'd be surprised
[01:09:39] <zeeshan> might as well
[01:09:44] <zeeshan> run everything as 3 phase
[01:09:50] <zeeshan> have you considerd a rotary phase converter?
[01:09:51] <ssi> https://pbs.twimg.com/media/BzuWwY0IQAAMEfd.jpg
[01:09:54] <ssi> see the big red cap?
[01:09:57] <ssi> that's all fan I think
[01:09:57] <ssi> heh
[01:10:14] <ssi> VFDs are cheaper than rotary phase converters :P
[01:10:25] <zeeshan> i guess you can replace it
[01:10:28] <zeeshan> with a regular fan
[01:10:32] <zeeshan> im sure its something standard
[01:10:40] <ssi> nah I'll run it
[01:10:45] <ssi> worst case, vfd
[01:10:48] <ssi> best case, start cap or something
[01:10:54] <zeeshan> yea
[01:10:58] <zeeshan> <- is learning german
[01:11:00] <zeeshan> gleichstrommotoren
[01:11:02] <zeeshan> means dc motors!
[01:11:09] <ssi> :)
[01:11:16] <ssi> bleistiftspitzer
[01:11:20] <ssi> means pencil sharpener!
[01:11:27] <zeeshan> rofl
[01:13:18] <zeeshan> dude
[01:13:20] <zeeshan> is it possible
[01:13:25] <Connor> ssi: So, you got different servo drives coming ?
[01:13:26] <roycroft> just remember to indicate the pencil before you attempt to sharpen it
[01:13:31] <zeeshan> that you have servos that only work with tachometers?
[01:13:44] <zeeshan> and nothing else?
[01:13:49] <toastydeath> i always used a collet closer to great success
[01:13:51] <toastydeath> for pencil sharpening
[01:13:55] <ssi> Connor: I have some AMC drives coming
[01:13:55] <toastydeath> no need to indicate
[01:13:59] <roycroft> you have a pencil collet?
[01:14:02] <XXCoder> ssi:
https://www.youtube.com/watch?v=EKL6elkbFy0
[01:14:04] <ssi> I'm not sure if what I bought is what I'll end up running permanently tho
[01:14:10] <Connor> ssi Cool. I thought you was short on $$$
[01:14:11] <toastydeath> for hex pencils you just pick the closest hex collet
[01:14:17] <ssi> Connor: I am
[01:14:18] <toastydeath> and round ones, obviously just pick a round collet
[01:14:27] <Connor> ssi: Credit Card Huh? :)
[01:14:27] <ssi> Connor: two of the drives I got were about $75 apiece
[01:14:33] <roycroft> what about lumber pencils?
[01:14:44] <ssi> Connor: yeah actually I stuck the VFD on a credit card
[01:15:18] <toastydeath> if i was sharpening lumber pencils frequently i imagine i'd have to machine a soft collet
[01:15:24] <toastydeath> not a big deal
[01:15:27] <toastydeath> still annoying though
[01:15:49] <Connor> Looking at your spindle.. you have PDB ON, PDB OFF, and Tool Inserted sensors..
[01:15:57] <Connor> not sure if you have a 180 out sensor like pete's
[01:16:30] <ssi> I think mine might be 1:1
[01:16:32] <ssi> not really sure yet
[01:16:38] <ssi> but the spindle motor itself is rated to 10k
[01:16:45] <Connor> Wow.
[01:16:46] <zeeshan> toastydeath: dont be cnc sharpening!
[01:16:51] <ssi> 15hp, 10krpm
[01:16:52] <ssi> weeee
[01:17:02] <toastydeath> cnc sharpening is the way to go
[01:17:20] <ssi> Connor: the books say something about a broken tool sensor
[01:17:21] <toastydeath> it was shop policy that all "home projects and stupid programs" be kept with O numbers in the 7000s
[01:17:24] <ssi> not sure how that works exactly :P
[01:17:29] <zeeshan> why would this cnc mill
[01:17:32] <zeeshan> have a hydraulic pump?
[01:17:44] <toastydeath> so i just kept the lathe program for "sharpen pencil" up there
[01:17:47] <zeeshan> to lubricatre the ball screws
[01:17:47] <ssi> zeeshan: I imagine because it has hydraulics :)
[01:17:48] <zeeshan> ?
[01:17:51] <Connor> That's probably one of those prox sensors I was just talking about.
[01:18:04] <zeeshan> ssi dont be a smart ass
[01:18:04] <ssi> probably
[01:18:05] <zeeshan> :)
[01:18:20] <ssi> I seriously doubt they'd use a hydraulic pump for lubrication
[01:18:36] <ssi> I'm very happy none of my machines have hydraulics
[01:18:57] <zeeshan> hm
[01:19:03] <zeeshan> im wondering where theyd be using hydraulics
[01:19:09] <zeeshan> maybe the tool changer is hydraulic
[01:19:13] <zeeshan> and not pneumatic..
[01:19:16] <zeeshan> that'd be weird.
[01:19:22] <ssi> very possible
[01:19:26] <DaViruz> my tool release is hydraulic
[01:19:34] <zeeshan> okay
[01:19:35] <Connor> Could be Hydraulic Boost.
[01:19:36] <ssi> the dunce cap looks too skinny to have a proper pneumatic drawbar
[01:19:40] <zeeshan> that explains why there is a stainless steel braded line
[01:19:41] <zeeshan> going to it..
[01:19:45] <DaViruz> it deoesn't bother mee except the pump mackes noise
[01:19:51] <zeeshan> ssi whats a dunce cap
[01:19:58] <Connor> that tall green thing
[01:20:07] <DaViruz> i also have a hydraulic vise which is nice sometimes
[01:20:20] <zeeshan> if we're gonna make fun of my machine
[01:20:23] <zeeshan> can we please do it in style?
[01:20:28] <zeeshan> that's a tapered dildo.
[01:20:33] <zeeshan> not a dunce cap.
[01:20:54] <zeeshan> i mean seriously
[01:20:57] <ssi> Connor: my machine came with a spare drawbar cylinder
[01:21:01] <zeeshan> these guys put up a hydraulic pump, reservoir
[01:21:03] <ssi> Connor: which I think would work for the griz ;)
[01:21:07] <zeeshan> just so they could have a compact tool changer?
[01:21:08] <zeeshan> wtf..
[01:21:15] <Connor> ssi Nice.. You sure? Looks a little big....
[01:21:50] <DaViruz> are pneumatic tool release cylinders more common? i think most i've ever seen have been hydraulic
[01:21:50] <zeeshan> ssi
[01:21:53] <zeeshan> do you have pics of your entire machine?
[01:22:04] <zeeshan> daviruz well the diy guys all really do pneumatic
[01:22:29] <ssi> Connor: yeah it might be a bit too big
[01:22:31] <DaViruz> understandable. i'm going pneumatic on my home built as well
[01:22:46] <ssi> zeeshan: what sort of pics
[01:22:52] <DaViruz> mostly because i happened to find some really nice big bore short stroke cylinders
[01:23:01] <zeeshan> like the whole machine
[01:23:02] <zeeshan> from far away
[01:23:03] <zeeshan> :D
[01:23:08] <zeeshan> to give an idea of its size
[01:23:32] <ssi> https://pbs.twimg.com/media/BzuZ7sSIYAAtckC.jpg:large
[01:23:44] <zeeshan> looks lonely
[01:23:55] <ssi> not now that there's an airplane in there
[01:23:56] <zeeshan> but damn
[01:23:58] <zeeshan> that doesnt take much space
[01:24:04] <ssi> heh
[01:24:11] <ssi> that's a 42'x37' hangar
[01:24:12] <Connor> ssi: zeeshan: PetefromTn: I hate all of you.. and your big a$$ space.. and you big a$$ machines...
[01:24:19] <ssi> the wing cutouts are 11x17'
[01:24:21] <zeeshan> connor
[01:24:22] <zeeshan> wtf
[01:24:22] <zeeshan> mate
[01:24:26] <Connor> :)
[01:24:26] <zeeshan> did you even see the pic i posted of my garage
[01:24:33] <zeeshan> where do you see big ass space!
[01:24:49] <zeeshan> ssi i didnt mean to hurt your manhood size
[01:24:50] <Connor> zeeshan: My shop is a 11' x 7' ROOM.
[01:24:58] <zeeshan> i was trying to say it fits perfect in your shop
[01:25:03] <zeeshan> :-)
[01:25:21] <ssi> I'm just trying to tell you it's not small
[01:25:24] <Connor> I have about 2' x 3' area to roll a chair around in.. If that much.
[01:25:31] <zeeshan> i never said it was!
[01:25:32] <ssi> it would take up all the space where your car is
[01:25:45] <zeeshan> you said it has 11'x11'
[01:25:46] <zeeshan> dedicated
[01:25:49] <ssi> https://pbs.twimg.com/media/BzuaWTqIcAAyZ_f.jpg:large
[01:25:50] <zeeshan> i know its big :)
[01:25:58] <ssi> with the freshly powdercoated chip/coolant trays
[01:26:08] <zeeshan> ricer!
[01:26:15] <zeeshan> looks great
[01:26:25] <zeeshan> whyd you pick white though
[01:26:28] <ssi> they're grey
[01:26:34] <zeeshan> i woulda made em black
[01:26:38] <zeeshan> so you never have to clean em again
[01:26:39] <zeeshan> :-)
[01:26:41] <ssi> heh
[01:27:24] <XXCoder> https://www.youtube.com/watch?v=dmvjScTx3lI
[01:27:27] <XXCoder> way too insane
[01:27:38] <XXCoder> im no lathe expert but iusnt that way too thick cut?
[01:27:42] <roycroft> black shows dirt more than any other color
[01:27:55] <zeeshan> XXCoder: i was doing that cut
[01:27:57] <zeeshan> on my lathe!
[01:28:24] <zeeshan> too bad it wasnt stainless
[01:28:25] <zeeshan> :(
[01:28:57] <XXCoder> is the cutting bit side magnetic?
[01:29:40] <zeeshan> this guy makes me mad
[01:29:44] <zeeshan> hes got stainless to waste
[01:29:45] <zeeshan> :-(
[01:29:49] <Connor> OKay... So, How bad is it to run USB and SATA parallel to 120v AC ?
[01:29:56] <XXCoder> yellow hot steel
[01:29:57] <ssi> hardinge AHCs make me sad
[01:30:06] <zeeshan> connor how lon of a run?
[01:30:08] <Connor> I'm pretty sure neither of them are shielded.
[01:30:19] <Connor> in side my enclosure.. maybe 18" ?
[01:30:21] <ssi> Connor: shouldn't be a problem at all
[01:30:26] <zeeshan> most of thsoe computers signals
[01:30:35] <zeeshan> have error checking
[01:30:37] <zeeshan> so its not a big deal
[01:30:49] <ssi> 60Hz ac isn't gonna induce that much noise in it
[01:30:57] <zeeshan> ssi
[01:30:58] <ssi> if it was high current stepper motor wires it'd be worse
[01:31:02] <zeeshan> arent the signals differential too?
[01:31:05] <ssi> cause they have fast edges that make lots of noise
[01:31:23] <ssi> I don't know if sata is differential
[01:31:26] <ssi> pretty sure usb isn't
[01:31:31] <Connor> those will run perpendicular to these.. so I'm good.
[01:31:45] <zeeshan> connor
[01:31:49] <zeeshan> you should have a speerate enclosure
[01:31:52] <zeeshan> for your computer!
[01:31:55] <zeeshan> and your drivers!
[01:31:57] * zeeshan is trolling
[01:32:04] <Connor> zeeshan: Not going to happen.
[01:32:08] <zeeshan> whenever someone says
[01:32:16] <zeeshan> "noise will be a problem"
[01:32:18] <Connor> I've had ZERO issues with it.
[01:32:19] <zeeshan> just show em my pic
[01:32:19] <zeeshan> !
[01:32:27] <XXCoder> he ruined the tool on lasrt inbe
[01:32:31] <XXCoder> last one
[01:32:38] <zeeshan> http://i.imgur.com/OOBcfTB.jpg
[01:32:41] <zeeshan> VFD in there too!
[01:32:47] <zeeshan> i had limit switch issues
[01:33:06] <zeeshan> pretty sure that toriod was emitting noise
[01:33:09] <zeeshan> wasn't the vfd for sure
[01:33:18] <ssi> I had issues on my plasma table, but the limit switches are in cable chain alongside stepper cables for like 20'
[01:33:22] <Connor> I don't have a VFD, and I'm using a switch PSU for the steppers.
[01:33:25] <ssi> a debounce component fixed it
[01:33:28] <zeeshan> do toriods emit noise?
[01:33:34] <ssi> not as much
[01:33:35] <zeeshan> psu
[01:33:43] <zeeshan> then what the hell was causing noise on my limit switcvhes
[01:33:45] <zeeshan> that i had to use debounce
[01:33:53] <Connor> the switches themselves.
[01:33:53] <zeeshan> it wasn't vfd, it wasn't transformer
[01:33:58] <zeeshan> nor was it the stepper drive
[01:34:00] <ssi> switches bounce
[01:34:03] <zeeshan> why
[01:34:04] <Connor> yup.
[01:34:11] <ssi> mechanical nightmare :)
[01:34:12] <zeeshan> how do they bounce
[01:34:14] <Connor> they make/break contact during the switching process.
[01:34:15] <zeeshan> haha shuddap
[01:34:19] <zeeshan> rofl that made me laugh
[01:34:36] <zeeshan> no i wouldn't even be close to closing em
[01:34:40] <zeeshan> and they'd be triggering
[01:34:48] <Connor> Weak or Cheap BOB.
[01:34:50] <ssi> yeah that's cable noise
[01:34:58] <zeeshan> its gotta be the bob
[01:35:06] <Connor> running parallel to the stepper motors ?
[01:35:07] <zeeshan> cause thats the only thing i couldnt test for
[01:35:07] <ssi> THE BOBS
[01:35:25] <zeeshan> connor yes
[01:35:26] <Connor> I have a issue with one of mine on my router...
[01:35:27] <zeeshan> but shielded cable
[01:35:34] <zeeshan> and the noise is there
[01:35:38] <zeeshan> whether the steppers are on/off
[01:35:42] <zeeshan> so i know its not the steppers
[01:35:47] <Connor> I'm using optical with a schmit trigger..
[01:36:11] <XXCoder> this is cool. fancy colors
https://www.youtube.com/watch?v=C4s4Cm8jmBs
[01:36:40] <zeeshan> does anyone know
[01:36:47] <zeeshan> if you can communicate using "Devicenet"
[01:36:48] <zeeshan> with linuxcnc
[01:37:22] <Connor> http://www.ivdc.com/cnc/case3.jpg
[01:37:33] <Connor> That's what my case looked like before I started work on it..
[01:37:48] <zeeshan> whats that stuff
[01:37:49] <zeeshan> on the very top?
[01:38:00] <zeeshan> with the black thing on it
[01:38:01] <Connor> Spindle Speed Controller.
[01:38:11] <zeeshan> ah okay
[01:38:22] <zeeshan> fancy twisted wires everywhere
[01:38:26] <Connor> with reverse ability, heat sink.. and under it is a large break resistor..
[01:38:38] <zeeshan> DC motor?
[01:38:40] <Connor> Yea.
[01:38:54] <zeeshan> holy cow
[01:38:56] <zeeshan> your motherboard is tiny
[01:39:01] <zeeshan> is that the atom mobo?
[01:39:04] <ssi> no YOUR motherboard is tiny
[01:39:09] <ssi> D:
[01:39:14] <zeeshan> ssi your face is tiny
[01:39:16] <Connor> I mounted it exactly the way your not suppose to.. manual specificly says mount it so that break is on top or side.. not on bottom.
[01:39:17] <XXCoder> thats whay she said
[01:39:22] <ssi> i ish
[01:39:23] <ssi> wish
[01:39:33] <Connor> Yes. It's a Atom 525D
[01:39:38] <zeeshan> shit dude
[01:39:39] <zeeshan> that's so small
[01:39:44] <zeeshan> i should look into that
[01:39:50] <zeeshan> but i already have a mobo ready to go
[01:39:56] <zeeshan> but if i get tied for space
[01:40:01] <Connor> 4GB Ram. 1 PCI Slot
[01:40:07] <zeeshan> dont you need like 2
[01:40:08] <zeeshan> for mesa
[01:40:12] <Connor> No.
[01:40:18] <Connor> 1 for the 5i25
[01:40:33] <Connor> has built in Ethernet, USB, and SETA
[01:40:52] <Connor> 4 USB on back, 2 USB headers
[01:40:53] <zeeshan> http://www.ebay.ca/itm/Sumitomo-VFD-AC-1-Phase-5-HP-Max-3-Phase-10-HP-Max-200-240-Volts-/171388500859?pt=LH_DefaultDomain_0&hash=item27e78cfb7b
[01:40:55] <zeeshan> is this the cheapest
[01:41:01] <zeeshan> ill ever find a brand new 10hp 3ph vfd?
[01:41:09] <zeeshan> i mean everywhere else i look
[01:41:11] <zeeshan> theyre 699
[01:41:15] <zeeshan> or 500 at least
[01:41:25] <zeeshan> connor nice
[01:41:27] <zeeshan> parallel port?
[01:41:45] <zeeshan> nm
[01:41:45] <Connor> Yes, it does have a built in pport too.. but, I have a 2ndary card in it at the moment..
[01:41:47] <zeeshan> i see a header
[01:41:56] <Connor> of course, I'm upgrading..
[01:41:59] <Connor> to the 5i25
[01:42:19] <Connor> yea, that machine has 3 pports on it right now.. the integrated one.. and the PCI which has 1 external and 1 on the header.
[01:42:31] <zeeshan> whats pushing you to do mesa
[01:42:34] <zeeshan> more i/o?
[01:42:40] <Connor> Yes.
[01:42:46] <zeeshan> nice
[01:43:00] <zeeshan> plus you said you were doing a rotary table
[01:43:00] <Connor> Plus.. I want some more exp with Mesa
[01:43:02] <zeeshan> so you need another axis
[01:43:08] <Connor> correct.
[01:43:28] <Connor> I have enough for it.. but.. I robbed my limit switches input for testing my touch probe.
[01:43:40] <zeeshan> haha
[01:43:57] <zeeshan> okay time for bed
[01:43:59] <Connor> but, adding I/O for the coolant pump, touch probes.. 4th axis... and spindle has a encoder on it..
[01:43:59] <zeeshan> GNITE!!
[01:44:07] <zeeshan> why i/o for coolant pump
[01:44:11] <zeeshan> so you can m8 from linuxcnc?
[01:44:16] <Connor> yea.
[01:44:23] <Connor> so the machine can turn coolant on/off
[01:44:32] <zeeshan> thats a luxury. :p
[01:44:45] <zeeshan> i personally dont like doing it through the control
[01:44:49] <zeeshan> even on big cnc machines
[01:44:52] <zeeshan> i always turned it on manually
[01:44:53] <Connor> When I get done with this machine.. it's going to have a PDB and a Tool changer.
[01:45:03] <zeeshan> but general people can forget
[01:45:06] <Connor> I already have the PDB built.
[01:45:41] <Connor> My only issue is.. I'm running out of room on the back for connectors..
[01:45:59] <zeeshan> are they 4 pin
[01:46:00] <Connor> I just have the DB9 and 2 of the 4 pin connectors left.
[01:46:12] <zeeshan> maybe you can change to 6 pin connectors
[01:46:14] <zeeshan> or even 8 pin
[01:46:43] <Connor> 5 x 4 pins, 1 connector for the spindle, 1 DB9, and 2 AC Euro plugs.
[01:47:30] <Connor> I might be able to make a larger plate.. or change out the Euro's for a a dongle style connector..
[01:47:46] <zeeshan> or get rid of one of your fans
[01:47:47] <zeeshan> :P
[01:47:51] <zeeshan> do you really need two?
[01:47:52] <zeeshan> :D
[01:48:09] <Connor> I have 1 open slot left.. but I was reserving that in case I needed to bring the 2nd Mesa port into the enclosure.
[01:48:16] <Connor> No. In fact, neither of them are wired up.
[01:48:28] <zeeshan> just river a plate in place of one
[01:48:33] <zeeshan> and you'll have tons more space
[01:48:34] <zeeshan> :P
[01:48:42] <zeeshan> *rivet
[01:48:57] <Connor> I'll use screws so I can remove the plate.. but, yea.. it might come down to that.
[01:49:13] <zeeshan> okay
[01:49:15] <zeeshan> must sleep
[01:49:16] <zeeshan> so tired!
[01:49:17] <zeeshan> gnite
[01:49:18] <Connor> I DO have a little room next to the DB9
[01:49:30] <Connor> I think that might be a SCSI knock out..
[01:49:34] <Connor> or DB25
[01:50:06] <ssi> :)
[01:52:42] <Loetmichel> mornin'
[02:31:14] <Deejay> moin
[02:56:22] <Jymmm> Deejay: I'm late, yu're fired!
[07:09:23] <Loetmichel> Jymmm: thats a bit of a problem, as he is a self employed farmer, last time i looked ;-)
[07:22:04] <IrrerIvan> hi there, i ran into some trouble setting up a joypad with Linuxcnc 2.6, maybe anyone can help me? For starters I would like to find out, how to set the jog value that also is displayed via a setp command
[07:46:44] <Jymmm> Loetmichel: Heh, nah, it's a running joke between us is all =)
[10:28:22] <archivist> so you want a large casting, come to England
http://www.bbc.co.uk/news/uk-england-south-yorkshire-29587196
[10:29:06] <malcom2073> Why would a pwmgen.n.pwm-freq 20 in the .hal file, result in it being 20 when I start linuxcnc?
[10:29:31] <malcom2073> setting it via halcmd after linuxcnc is running seems towork fine
[10:29:56] <archivist> are you confusing frequency with pwm
[10:30:29] <malcom2073> No, I'm trying to set the pwm frequency, not the duty cycle
[10:30:43] <malcom2073> if it's set to 0, it runs at full speed (whatever the thread is running at)
[10:30:52] <malcom2073> which is bad, since my SSR's can't handle that heh
[10:31:22] <archivist> your original question seems like it does exactly what you asked
[10:31:30] <malcom2073> Whups
[10:31:34] <malcom2073> Why would a pwmgen.n.pwm-freq 20 in the .hal file, result in it being 0 when I start linuxcnc?
[10:31:37] <malcom2073> ^^ proper question
[10:31:53] <malcom2073> You're right, I asked a stupid question the first time around :)
[10:32:07] <archivist> I am awake it seems
[10:32:12] <malcom2073> Indeed, I am not.
[10:32:25] <malcom2073> Nothing else in the hal file touches the pwm-freq, is there some other configurationI may be missing that could be setting it back to 0?
[10:32:37] <archivist> is it waiting to be enabled
[10:32:39] <malcom2073> Or, does changing things like max-dc, reset the pwm-freq to 0?
[10:32:50] <malcom2073> It is enabled before the pwm-freq is set in the hal file, should I enable it after?
[10:33:16] <archivist> order matters for some things, dunno about that one
[10:33:27] <malcom2073> I'll try moving it around, see if that helps
[10:35:08] <malcom2073> hmm, enablign before/after setting it doesn't seem to help, neither does setting it first, or last in the file
[10:35:27] <malcom2073> setting it via command line works after linuxcnc is running though, so something between loading the config file, and the UI coming up, is setting it to 0
[10:42:22] <malcom2073> Hmm, doesn't seem so
[10:46:31] <malcom2073> Can I do: setp wcomp.0.min <= encl.temp.measure - 20 where encl.temp.measure is a float signal?
[10:47:06] <malcom2073> or rather, net
[10:47:09] <malcom2073> not setp
[10:50:24] <zeeshan> hi!
[10:50:31] <malcom2073> Hi!
[10:51:23] <zeeshan> has anyone heard of the brand sumitomo?
[10:51:24] <zeeshan> http://www.sumitomodrive.com/
[10:51:25] <zeeshan> ?
[10:52:16] <zeeshan> http://www.ebay.ca/itm/Sumitomo-VFD-AC-1-Phase-5-HP-Max-3-Phase-10-HP-Max-200-240-Volts-/171388500859?pt=LH_DefaultDomain_0&hash=item27e78cfb7b
[10:52:18] <zeeshan> looking to buy one of these
[10:54:18] <jdh> sumitomo does everything
[10:54:44] <zeeshan> is it a good reliable brand
[10:55:22] <jdh> made for an elevator, I'd imagine is is good.
[10:56:39] <zeeshan> im looking at it how it communicates
[10:56:46] <jdh> the nameplate doesn't mention single phase input
[10:56:46] <zeeshan> it uses the devicenet protocol
[10:56:49] <zeeshan> using rs485
[10:56:54] <zeeshan> jdh yea its 3 phase
[10:56:57] <zeeshan> im using it on a 5 hp motor
[10:57:10] <jdh> you have 3phase power?
[10:57:14] <zeeshan> no
[10:57:20] <zeeshan> all vfds are 3 phase
[10:57:24] <zeeshan> you can run them off single phase
[10:57:30] <jdh> 11:37 < jdh> the nameplate doesn't mention single phase input
[10:57:35] <zeeshan> so?
[10:57:46] <zeeshan> [11:37:57] <zeeshan> all vfds are 3 phase [11:38:01] <zeeshan> you can run them off single phase
[10:58:06] <zeeshan> the ones that say single phase input
[10:58:09] <zeeshan> just have larger capacitors
[10:58:12] <zeeshan> and transistors
[10:58:27] <zeeshan> so whenever you buy a 3 phase vfd , and are trying to run say a 2 hp motor
[10:58:39] <zeeshan> you'd end up running a 4 hp drive if youre providing it single phase
[10:59:16] <Loetmichel> *gnah* what did i start as i helped my sister plan the wiring in her new house... i had just a call from my bother in law to be... 15 minutes of "whcih cable will go wehere and how much should i order for each component?"... i see a lot of masonary work coming to me... (as the walls in germany tend to be massive stone/bricks)... i should ask my boss for a few weeks off soon i fear ;-)
[10:59:51] <jdh> no, you should say "I'm sorry, I don't use windows so I can't really help"
[11:00:28] <jdh> (or the equivalent... that is what I do when friends/family ask about computer problems)
[11:00:49] <Loetmichel> ahem.
[11:01:13] <jdh> s/windows/residential wiring/
[11:02:11] <Loetmichel> my sister may be a hairdresser by profession... but she has worked the last 4 years as an WIn/linux Admin... so she can pretty much hold her own there... (and if not she asks me for telephone support)... but electric wiring requires a "facharbeiter" in germany i.e. someone who has the certificates to do it...
[11:02:18] <Loetmichel> ... which would be me ;-)
[11:02:45] <jdh> time sink.massive.
[11:03:02] <zeeshan> lol
[11:49:16] <zeeshan> "Two very different types of lathes typically used to turn two types of materials. What are they ? (do not use "and" or comma...just name the two, soft material first, one space between names. [If you have trouble with this email don@practicalmachinist.com but be prepared with a short bio on yourself so I can tell you are not a spammer. ]"
[11:49:21] <zeeshan> wtf is this question asking me
[11:49:43] <zeeshan> i wrote aluminum steel
[11:49:46] <zeeshan> and thats not the answer.
[11:51:05] <Rab> wood/metal :P
[11:51:09] <zeeshan> i tried that too
[11:51:09] <zeeshan> lol
[11:51:11] <zeeshan> "wood metal"
[11:51:12] <zeeshan> failure
[11:52:32] <Rab> Haha, maybe wood is considered "harder" since it's less ductile? (Lignin fracturing rather than displacing.)
[11:52:38] <Rab> Beats me.
[11:52:38] <zeeshan> i tried both ways :P
[11:52:55] <zeeshan> trying to restore my password prac. machinist form
[11:52:56] <zeeshan> forum
[11:54:30] <archivist> types of lathes, not types of material!
[11:54:44] <archivist> read the question
[11:55:00] <zeeshan> oh
[11:55:04] <zeeshan> engine and turret ?
[11:56:44] <zeeshan> engine turret doesnt work nor does turret engine work :P
[11:56:58] <archivist> hand turning for wood, engine for metal
[11:57:42] <archivist> but as a hand turner of metal I dispute that question
[11:57:49] <zeeshan> haha

[11:58:35] <XXCoder> wood lathe and metal lathe
[11:59:06] <zeeshan> yea
[11:59:07] <archivist> pole lathe is made of wood and turns wood
[11:59:10] <zeeshan> but tyhe thing doesnt work

[11:59:19] <zeeshan> trying to restore my password
[11:59:23] <zeeshan> but that way is so retarded.
[11:59:35] <XXCoder> I suspect there is more specific names
[12:00:28] <archivist> the question is retarded because you can turn wood on a metal cnc lathe
[12:00:45] <XXCoder> but not reverse
[12:01:01] <XXCoder> so far I know anyway
[12:01:34] <zeeshan> haha thats true
[12:02:04] <archivist> I am pretty sure I could hand turn metal on a wood lathe
[12:02:08] <Tom_itx> you can shape metal on a wood lathe
[12:02:13] <zeeshan> you can even turn metal
[12:02:17] <zeeshan> on a metal lathe by hand
[12:02:27] <zeeshan> its a bit dangerous :P
[12:02:28] <archivist> spinning lathe too
[12:02:35] <XXCoder> http://www.woodworkingtalk.com/f6/why-no-turning-metal-wood-lathe-23565/
[12:03:01] <CaptHindsight> http://en.wikipedia.org/wiki/Metal_lathe#Types_of_metal_lathes Center lathe / engine lathe / bench lathe
[12:03:18] <zeeshan> i give up on the answer
[12:03:21] <zeeshan> im not restoring my password
[12:03:21] <zeeshan> !!!
[12:03:29] <XXCoder> essay it is then lol
[12:04:45] <CaptHindsight> Toolroom, turret, capstan, gang-tool, multispindle, cnc, swiss, combination, mini, micro, wheel, lathe, oil country are how wikipedia lists them
[12:05:12] <zeeshan> The answer given for the random question was incorrect.
[12:05:13] <zeeshan> !
[12:05:53] <CaptHindsight> why didn't he just post the answers and then ask for the question?
[12:06:05] <zeeshan> haha
[12:06:09] <zeeshan> cause he's retarded
[12:06:14] <zeeshan> its so frustrating
[12:06:44] <XXCoder> zeeshan: there is lternate way
[12:06:54] <XXCoder> just write short summary about yourself and email
[12:06:57] <zeeshan> no
[12:07:00] <CaptHindsight> or ask "I have my own idea of how to categorize lathes, how do I categorize them into only two categories?"
[12:07:01] <zeeshan> i dont have time for that non sense
[12:07:08] <zeeshan> summary about myself
[12:07:09] <zeeshan> ..
[12:07:09] <zeeshan> ROFL
[12:07:16] <zeeshan> "i am noob, give me password."
[12:07:18] <XXCoder> you probably took more time figuring answert than that already
[12:08:20] <zeeshan> :D
[12:08:26] <zeeshan> time for FOOD!@
[12:08:39] <zeeshan> and youre right
[12:08:42] <CaptHindsight> how many kinds of wrenches are there? (BTW I am always right, very important and take myself very seriously)
[12:08:42] <zeeshan> i wasted more time guessing :P
[12:08:52] <zeeshan> 987498
[12:09:28] <XXCoder> capt more than there is atoms in universe. ;)
[12:09:35] <CaptHindsight> sounds like whoever wrote that recovery question would make a great public school teacher
[12:09:40] <Tom_itx> there are but two kinds of wrenches
[12:09:48] <Tom_itx> the right one for the job and the wrong one
[12:11:05] <syyl_ws> you can still bang with the wrench on stuff
[12:11:10] <syyl_ws> then its the right one ;)
[12:12:07] <CaptHindsight> they still teach that gravity pulls on things /end rant
[12:13:57] <archivist> well gravity does not push
[12:16:13] <syyl_ws> its just an inverted pull
[12:16:14] <syyl_ws> ;)
[12:17:10] <SpeedEvil> The earth sucks
[12:19:00] <syyl_ws> :D
[12:22:20] <CaptHindsight> my suggestion: "Read my mind and tell me what I'm thinking. [If you have trouble with this email don@practicalmachinist.com but be prepared with a short bio on yourself so I can tell you are not a spammer. ]"
[12:25:15] <kfoltman> notverypracticalmachinist.com
[12:32:04] <syyl_ws> haha
[12:32:10] <syyl_ws> practical machinist is awesome
[12:32:11] <syyl_ws> :D
[12:32:24] <syyl_ws> some people there got a pretty good sized stick up there but..
[14:43:37] <nofxx> anyone running solidworks on vmware? vbox crashes the photoview =/
[14:45:24] <CaptHindsight> I've had problems with some versions of Solidworks on Winders
[14:45:34] <t12> i run it in fusion
[14:45:35] <t12> poorly
[14:46:18] <nofxx> all works nice, it's even fast, but photoview crashes... no fun hehe
[14:46:50] <nofxx> what's getting me frustated is that it works 1/20 times you try
[14:47:08] <Jymmm> google it, you cna't be the only one with the issue.
[14:47:40] <nofxx> Jymmm, didn't came here first, guarantee you..
[14:47:57] <humble_sea_bass> i keep my thinkpad from college around just for solidworks in shop
[14:48:14] <Jymmm> nofxx: So you contacted vmware tech support and asked?
[14:48:21] <humble_sea_bass> because SW in a VM is nothing but tears
[14:48:38] <Jymmm> humble_sea_bass: hardly, mine is fine.
[14:48:47] <ReadError> i only run SW in a VM...
[14:48:53] <ReadError> works 100%
[14:48:56] <nofxx> humble_sea_bass, cad world is stuck in the 90's , who uses windows nowdays? damn
[14:49:13] <humble_sea_bass> i guess I have an armada of bad laptops
[14:49:21] <nofxx> Jymmm, got virtuabox, don't wanna install all again in vmware to verify it won't work
[14:49:29] <nofxx> was asking here first, but lets try some search too
[14:49:39] <ReadError> vbox kinda sucks compared to vmware
[14:49:41] <ReadError> just sayin
[14:49:49] <ReadError> or parallels
[14:49:51] <ReadError> =
[14:50:40] <nofxx> btw, freecad is really nice, give it 2 or 3 years I guess won't be much for inventor or solidowrks
[14:50:59] <nofxx> for now there's no assembly...
[14:51:06] <nofxx> bugged branch only*
[14:51:58] <nofxx> maybe 5.. hehe, need to take my hat off, 3D cad software is tricky
[14:52:53] <humble_sea_bass> 2 or 3 years nad it will fork
[14:52:58] <ReadError> solidworks was the easiest for me to pick up
[14:53:04] <ReadError> stuff just made sense
[14:53:10] <humble_sea_bass> because someone used MIT license vs GNU
[14:53:13] <ReadError> dont see any point in switching at this point
[14:53:33] <humble_sea_bass> solidworkds is the cats pajamas
[14:53:49] <nofxx> humble_sea_bass, it's LGPL, imho MIT/LGPL way better than GPL, why do you think otherwise?
[14:54:03] <nofxx> ReadError, true, more intuitive
[14:54:23] <humble_sea_bass> 7there isnt enough weed on earth to fall for your troll nofxx
[14:54:24] <nofxx> or least surprise*
[14:54:54] <nofxx> humble_sea_bass, there is... DWTFYW.. my personal favorite ;)
[14:55:53] <nofxx> humble_sea_bass, or honey B or tangerine dream
[14:56:46] <humble_sea_bass> anyhow. solidworks...
[14:57:45] <ReadError> nofxx seeing as its been around for 12 years
[14:57:56] <ReadError> duno how you expect it to be at SW level in 2
[14:58:37] <humble_sea_bass> sw is just the siemens nx engine with a custom interface
[14:58:45] <nofxx> ReadError, it's getting attention just 2, 3 years from now
[14:59:00] <nofxx> ReadError, and got somehow usable... now with the userbase things go faster
[14:59:34] <nofxx> ReadError, also, if you try it you going to start using with no issues, it's really "based" on solidworks hehe
[15:00:19] <nofxx> actually it's a game of synonyms dictionary hehe...
[15:00:52] <nofxx> boss -> pad , cut -> pocket
[15:02:30] <nofxx> pretty much the same the rest... loft, sweep, fillet, mirror, booleans
[16:03:05] <zeeshan> fak
[16:03:10] <zeeshan> i scavenged some money and bought that vfd
[16:03:19] <zeeshan> only one left now
[16:03:29] <zeeshan> it was selling like hot cakes at the price
[16:06:25] <jdh> do hotcakes sell quickly
[16:07:21] <zeeshan> yes
[16:07:29] <zeeshan> delkicious hotcakes
[16:07:33] <zeeshan> http://www.plccenter.ca/Buy/SUMITOMO%20MACHINERY%20INC/HF43027A5?redirect=true
[16:07:37] <zeeshan> this drive goes for like 1k
[16:07:46] <zeeshan> hes got a bunch of them brand new for 345
[16:15:41] <jdh> WARNING: DO NOT USE WITH SINGLE PHASE
[16:16:15] <zeeshan> ??
[16:16:29] <jdh> on that page
[16:16:57] <jdh> oh, I misread that... it really says Estimated Retail Price - $1,630.00
[16:17:11] <zeeshan> you really need to take a regular 3 phase vfd
[16:17:14] <zeeshan> and put in 1 phase in it
[16:17:49] <zeeshan> https://www.google.ca/search?q=single+phase+3+phase+vfd&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:en-US:official&client=firefox-a&channel=sb&gfe_rd=cr&ei=a-s6VNfeKKPE8gf174CoBQ
[16:17:55] <jdh> I have, but they all have singlephase nameplates
[16:18:07] <zeeshan> well that just means the components in them
[16:18:09] <zeeshan> can handle the extra load
[16:18:19] <jdh> but... for my uses, the price is not so important.
[16:18:34] <zeeshan> for me price is everything
[16:18:38] <zeeshan> and finding a single phase 5 hp drive
[16:18:41] <zeeshan> is almost impossible
[16:18:48] <zeeshan> basically all vfds work the same way
[16:18:57] <zeeshan> ac power in, rectified to DC
[16:19:13] <zeeshan> that voltage then gets sent to switching amplifiers
[16:19:25] <zeeshan> thats how it modifies the sine wave output
[16:19:53] <zeeshan> so instead of going through 3 bridge rectifiers
[16:20:05] <zeeshan> its going through one, and its seeing more power
[16:20:13] <zeeshan> that's how i see it working
[16:21:41] <pcw_home> The issue with running on single phase is ripple (and ripple current in the filter capacitors)
[16:22:22] <zeeshan> yes
[16:22:31] <zeeshan> but thats why you derate the 3 phase vfd by 2
[16:22:38] <zeeshan> 10hp 3phase for 5 hp single phase
[16:22:48] <zeeshan> so that the caps can handle the ripple thats happening every 120 deg
[16:24:26] <zeeshan> http://www.practicalmachinist.com/vb/transformers-phase-converters-vfd/how-avoid-de-rating-3phase-only-vfds-152794/
[16:24:27] <zeeshan> ha interesting
[16:24:39] <zeeshan> this thread talks about using a 5 hp 3 phase to run off 1phase
[16:24:42] <zeeshan> to drive a 5 hp motor
[16:24:55] <zeeshan> by using an external bridge rectifier and cap
[16:25:03] <Deejay> gn8
[16:27:30] <zeeshan> too hardcore for me :P
[16:33:58] <pcw_home> If the DC bus was brought out you could probably add capacitors and not have to de-rate for single phase
[16:34:00] <pcw_home> 3 phase makes everything easy since power is always suppled (instead of going away 120 times a second)
[16:34:01] <pcw_home> (and even without filter capacitors you have only a small amount of ripple)
[16:37:51] <zeeshan> pcw_home: is it true
[16:38:13] <zeeshan> that you could technically provide DC voltage directly to the switching amplifiers
[16:38:19] <zeeshan> and have it work correctly?
[16:38:28] <zeeshan> and by pass the entire filtering/rectifying circuit
[16:38:31] <zeeshan> (input side)
[16:57:57] <pcw_home> Sure, the VFD runs on DC , but a 3 phase rectifier is the most economical way to get large amounts of DC power
[17:05:09] <zeeshan> ah
[17:07:39] <pcw_home> (most economical for low ripple DC power I should say)
[17:07:40] <pcw_home> single phase is fine if you dont care about the ripple but filtering single phase is expensive
[17:09:27] <pcw_home> (since with single phase, your capacitors have to supply the total load power for a brief time120 times a second)
[17:18:55] <zeeshan> they must be beefy capacitors
[18:06:38] <Jymmm> zeeshan: corn fed capacitors?
[18:30:08] <zeeshan> Jymmm: yes
[18:30:51] <Jymmm> zeeshan: Non GMO ?
[18:30:57] <zeeshan> nope!
[18:30:57] <zeeshan> :P
[18:31:03] <Jymmm> Bastard!
[18:31:04] <zeeshan> don't need mutant vfd
[18:31:28] <Jymmm> zeeshan: if it's non-go that WOULD be mutan vfd
[18:31:35] <Jymmm> non-gmo*
[19:18:00] <somenewguy> I am learning python. yay me
[19:18:24] <somenewguy> am I better served dealing w/ 2.x since I assume that is what linuxcnc is using for hte forseeable future?
[19:33:15] <maZer`-> hi all
[19:34:11] <maZer`-> i build a custom mdi script wich i can run over pyvcp, is there a way i can insert code that will ask me every time like "are you sure you want to run this command?"
[19:34:17] <maZer`-> yes | no :D
[19:53:26] <maZer`-> noone idea :(
[19:56:01] <jdh> no clue
[19:57:13] <tjtr33> maZer`-, i think its possible. because you could write a python M1xx code, and that code could ask for the response.. I been looking to see if it was a 'good' idea, and cant find anything saying 'here's how' nor cani find 'dont do that'
[19:57:19] <tjtr33> so give it a try
[19:58:38] <tjtr33> hmm can write it bash too
[19:58:38] <jdh> you could, perhaps, have one pyvcp button that said 'run this script' that actually just enables another button that says, "yes, I really do want to run this script and crash the spindle"
[19:58:56] <tjtr33> but dont exec it right away
[19:59:06] <tjtr33> alway do the frkn M$ are you sure
[19:59:19] <maZer`-> big thanks
[19:59:46] <jdh> and after the third crash after someone clicked 'yes', pop up another one that says "are you really really sure"
[19:59:53] <maZer`-> haha
[20:00:14] <jdh> after you run it 10 times, the 11th time you will hit the 'are you sure' by rote.
[20:00:31] <maZer`-> i have a script that will touch the tool length, and i just want to ask for "you want to write this value into tool table?" :)
[20:04:22] <tjtr33> still unsure if its a good idea, but i do wrap bash command scripts with 'zenity' a tiny gui
[20:08:27] <jdh> if you are using pyvcp, I would assume you could do that in pyvcp by enabling/disabling other options. But, I've never written any pyvcp :)
[20:09:47] <maZer`-> ahh ok
[20:09:47] <maZer`-> :D
[20:12:32] <maZer`-> and just last question
[20:13:22] <maZer`-> is there a way to switch to a absolute coordinate system that also absolute from the home ? also a coordinate system that is not to be able to be zerod
[20:14:20] <jdh> like G90?
[20:15:00] <maZer`-> ahhm no because that will only switch the mode i will travel
[20:15:16] <maZer`-> i mean to switch to a coordinate system that is not changeable by user
[20:15:40] <maZer`-> default is g54 i think
[20:28:50] <tjtr33> http://linuxcnc.org/docs/devel/html/gcode/gcode.html#sec:G53-Move-in
[20:29:37] <maZer`-> AHHHH yes big big big thanks! i searched this
[21:25:37] <ssi> HI
[22:08:25] <ssi> pete
[22:08:38] <PetefromTn_andro> Hello
[22:09:08] <ssi> it's dead in here tonight
[22:09:17] <ssi> I was hoping to put some heads together about this weird fan grease issue :)
[22:10:28] <PetefromTn_andro> Well I already told you what I thought but I'm open for discussion LOL
[22:10:47] <ssi> what did you tell me?
[22:11:20] <PetefromTn_andro> In our text session earlier Today
[22:11:25] <ssi> yeah I just re-read it
[22:11:33] <ssi> you said that it looks like yours, but yours didn't have grease
[22:12:00] <PetefromTn_andro> I seriously doubt it has anything to with keeping chips out really
[22:12:19] <ssi> what in the world is it there for?
[22:12:34] <ssi> there's a metal ring that was snapped into the housing below the fan that seems to be there to keep the grease in place
[22:12:48] <ssi> the grease was packed like 1" thick all around the outside of the housing, and the tips of the blades drag through it
[22:12:48] <PetefromTn_andro> I honestly don't think it is supposed to have that grease in it
[22:12:52] <ssi> super weird
[22:12:58] <ssi> where the hell did it come from then?
[22:13:09] <ssi> it's way too much clean grease to have gotten there from years of filthy use
[22:13:16] <ssi> it's seriously like a whole tube of grease
[22:13:25] <ssi> there's no zerks or anything
[22:13:29] <ssi> it's on the inside of a plastic housing
[22:13:29] <PetefromTn_andro> I have no idea man. Especially if the blades hit the grease
[22:13:35] <ssi> so weird
[22:13:47] <ssi> the spindle motor itself is a big square can, and the top of it when you remove the fan housing is sealed
[22:13:58] <ssi> and it's covered in a layer of grease that looks like it was slung there by the fan
[22:14:07] <PetefromTn_andro> Yeah that's similar to mine
[22:14:22] <ssi> well you've got the shaft coming out the top, right?
[22:14:26] <ssi> for the resolver/encoder?
[22:14:53] <PetefromTn_andro> I wonder if a previous owner did it for some strange reason
[22:15:40] <ssi> https://pbs.twimg.com/media/Bzy4ZygIUAAwqG-.jpg:large
[22:15:53] <PetefromTn_andro> Yeah it has a stub shaft for the resolver encoder and a dust seal in the top of the housing
[22:16:01] <ssi> yeah mine doesn't have that
[22:16:07] <ssi> there's an encoder, but I'm not sure yet where it is :)
[22:16:38] <PetefromTn_andro> Those slots in the sides are for air flow
[22:16:42] <ssi> yeah
[22:17:01] <PetefromTn_andro> So I cannot imagine any reason to have grease in the area
[22:17:11] <ssi> well I brought the housing and fan home
[22:17:16] <ssi> I'm gonna throw it in the parts washer and clean it out
[22:17:28] <ssi> I hope the plastic housing is kerosene safe :P
[22:17:41] <PetefromTn_andro> Is your encoder on the spindle somehow?
[22:17:46] <ssi> not sure!
[22:17:54] <ssi> it's certainly not on the top of the motor
[22:18:12] <ssi> but on the electrical box on the side of the motor, up at the top, the 3ph for the spindle and the 3ph for the fan and the encoder cable all terminate
[22:18:27] <PetefromTn_andro> Well it could be under that cover on top of the motor possibly
[22:18:47] <ssi> could be
[22:19:08] <PetefromTn_andro> It looks like it might unscrew
[22:19:14] <ssi> yeah it does
[22:19:28] <PetefromTn_andro> Does the three phase wiring go in that area
[22:19:30] <ssi> you can see I knocked the grease off one of the pan head screws on the lower left
[22:19:44] <ssi> I think it might go in the wide spot on the left side
[22:20:41] <PetefromTn_andro> WTF?
[22:20:45] <ssi> lol
[22:21:10] <PetefromTn_andro> It said disconnected for timeout or something like that
[22:21:37] <ssi> yeah that happens
[22:21:45] <PetefromTn_andro> Oh okay
[22:22:26] <PetefromTn_andro> My kids are going to school Tuesday after falling break here
[22:22:39] <ssi> I'm wondering if tomorrow is a work holiday
[22:22:39] <PetefromTn_andro> Fall
[22:22:55] <PetefromTn_andro> What's tomorrow again?
[22:22:59] <ssi> columbus day
[22:23:04] <PetefromTn_andro> Aah
[22:23:18] <PetefromTn_andro> Should be anyway LOL
[22:24:16] <PetefromTn_andro> Had a guy that bought a rifle from a former customer. Contact me about some parts he wants made.
[22:24:26] <ssi> nice
[22:24:31] <ssi> I have a small job for the laser
[22:24:46] <ssi> bunch of endcaps for podponics's light extrusion, out of 1/4" acrylic
[22:24:52] <PetefromTn_andro> Yeah I know him and we shot together several times before
[22:25:10] <PetefromTn_andro> Sweet
[22:25:27] <PetefromTn_andro> any word on that other job?
[22:25:34] <ssi> no, still waiting to hear back from davidson
[22:25:47] <ssi> forrest is still designing the rectifier board, which is what goes in those bxes
[22:25:59] <PetefromTn_andro> Okay
[22:26:05] <ssi> my guess is they'll drag their feet until the boards are back and assembled, and then suddenly it'll be a mad rush to get them done
[22:26:08] <ssi> that's sort of how they operate
[22:26:23] <PetefromTn_andro> you'll probably have your machine working by the time it's ready LOL
[22:26:27] <ssi> might :P
[22:26:43] <ssi> I dunno, I got set back a week with this drive debacle :P
[22:26:51] <ssi> I should have my VFD this week though, and a couple of the AMC drives
[22:26:58] <PetefromTn_andro> Oh just a week..
[22:27:07] <ssi> set back a week, yes
[22:27:11] <PetefromTn_andro> Sigh
[22:27:14] <ssi> because I have to wait for drives to be shipped
[22:27:21] <ssi> doesn't mean I'll be done in a week
[22:27:30] <ssi> just means it'll take at least a week longer than it would have otherwise :P
[22:27:46] <ssi> and the drives I bought may not even work for me
[22:27:47] <PetefromTn_andro> Take your time and do it right man
[22:28:26] <ssi> ...
[22:28:28] <ssi> k never mind
[22:28:29] <ssi> going to watch tv
[22:29:36] <PetefromTn_andro> Did I say something wrong?
[22:30:19] <ssi> the implication that I'm not "doing it right" is somewhat insulting
[22:30:51] <PetefromTn_andro> Where did I imply that you were not doing anything right?
[22:31:02] <ssi> three minutes ago

[22:55:07] <gammax> Evening all
[22:55:54] <gammax> Anyone selling some mesa cards?! :D
[22:57:42] <somenewguy> I think mesa is
[23:01:35] <somenewguy> should I be learning how to use python2 or 3? I'm lazy and want to commit. it seems like everything i play w/ that mentions python mentions 2, but linuxcnc is most important to me
[23:03:02] <gammax> im lookin for some used ones or scratch dent!
[23:10:00] <gammax> Cant decide if i should try to repair my lathemate hardinge or just swap to linux cnc
[23:11:32] <zeeshan> linuxnc
[23:11:33] <zeeshan> cnc
[23:11:49] <zeeshan> starting to fall in love with the mill
[23:12:00] <zeeshan> it puts my manual mill to shame!
[23:12:01] <zeeshan> http://i.imgur.com/WOEAa3v.jpg
[23:12:04] <zeeshan> those ways are beefy
[23:12:26] <zeeshan> im in the process of cleaning up the years of dirt on this thing
[23:12:53] <somenewguy> oh baby
[23:13:20] <XXCoder> beefy indeed
[23:13:24] <XXCoder> its cnc mill?
[23:13:26] <zeeshan> yea
[23:13:29] <zeeshan> the bottom way
[23:13:33] <zeeshan> has a v
[23:13:37] <zeeshan> well
[23:13:45] <zeeshan> \- that type of shape
[23:14:10] <zeeshan> http://i.imgur.com/BJwxuvO.jpg
[23:14:40] <zeeshan> about the same for the z i'd say
[23:14:46] <zeeshan> slightly bigger
[23:15:16] <XXCoder> damn its big
[23:15:23] <XXCoder> how much did you pay again?
[23:15:29] <zeeshan> 2k
[23:15:46] <zeeshan> i was taking it apart
[23:15:48] <zeeshan> to check out the ways
[23:15:51] <zeeshan> and theyre pretty mint
[23:15:55] <XXCoder> pretty cheap but then no idea
[23:18:24] <zeeshan> i wish there was some way to jog the motors
[23:18:35] <zeeshan> so i can take it apart more easily
[23:18:45] <zeeshan> i guess i can disconnect the servos
[23:18:53] <zeeshan> which i should do anyway to test them off the machine
[23:19:56] <zeeshan> they were definitely using this machine to drill pcbs
[23:20:07] <zeeshan> i found a replica of a circuit board
[23:20:09] <zeeshan> on the table.
[23:20:09] <zeeshan> lol
[23:20:17] <zeeshan> bastards drilled like 1mm holes in one spot of it
[23:22:39] <somenewguy> you gonna finish wiring it?
[23:25:33] <zeeshan> somenewguy: after i take it all aprt first
[23:25:37] <zeeshan> i wanna go over everything
[23:25:45] <somenewguy> oh no i mean the circuit board they left for you
[23:25:53] <somenewguy> ;)
