[00:57:30] <ssi> Connor: in addition to quadrature
[00:57:35] <ssi> the grey code is the commutation signal
[01:22:50] <Connor> ssi What' exactly is that used for ?
[02:17:12] <Deejay> moin
[07:35:57] <jdh> I think geminis use ecoder for comutation, after finding the halls
[07:43:43] <ReadError> http://www.cncrouterparts.com/images/2012-03-08%2006.47.52.jpg
[07:43:52] <ReadError> is there a standard as to how high these things are?
[07:56:37] <ReadError> ahh seems to be 1/2" to the center
[08:05:27] <elmo401> there is no standard...
[08:08:47] <Jymmm> how high?
[08:11:39] <ReadError> yea, cncrp doesnt publish dimensions
[08:12:06] <ReadError> but I have one its just hard to get too, was able to figure it out
[08:12:27] <ReadError> doing a 4 axis wire cutter and they come monday but im still making parts for it
[08:20:29] <Jymmm> so there are no drawings or specs?
[08:24:53] <Jymmm> ReadError: I'd guess no more than double the leadscrew diameter
[08:26:29] <Jymmm> ReadError: 4 axis wire cutter?! What you cutting wire on a bevel? lol
[08:27:03] <Jymmm> ReadError: slicing it lengthwise?
[08:27:57] <Jymmm> ReadError: Making decrotive swans out of it?
[08:35:41] <SpeedEvil> http://www.telegraph.co.uk/culture/culturepicturegalleries/7916457/Pencil-sculptures-miniature-masterpieces-carved-into-graphite-by-Dalton-Ghetti.html
[08:35:47] <SpeedEvil> but in wire
[08:37:03] <ReadError> Jymmm hot wire'ing some wings
[08:37:34] <Jymmm> ReadError: hot wire foam cutter?
[08:39:21] <ReadError> http://www.youtube.com/watch?v=g7sJmPijP_0#t=54
[08:44:42] <Jymmm> ReadError Like I said, HWFC. Now, THIS is a foam cutter...
https://www.youtube.com/watch?v=typOpfYqjdk
[08:45:28] <Jymmm> or this
https://www.youtube.com/watch?v=JP2EzntCOgY
[08:45:38] <Jymmm> I cant find the one I was thinking of
[08:45:40] <malcom2073_> ReadError: That's nuts loud lol
[08:47:52] <ReadError> last of the parts will be here monday
[08:48:42] <Jymmm> ReadError: what are you using for heat control?
[08:49:01] <ReadError> variac
[08:49:09] <ReadError> and a transformer
[08:49:10] <Jymmm> AC?
[08:49:20] <ReadError> well ac->dc
[08:49:41] <ReadError> I have a lab PSU but I use it for a bunch of other stuff
[08:49:51] <Jymmm> you're gonna fry your xfmr using a variac (eventually)
[08:50:23] <ReadError> hmm im open to suggestions
[08:50:40] <Jymmm> Try it, just keep an eye on it.
[08:50:57] <Jymmm> Much better than a dimmer switch =)
[08:51:29] <Jymmm> Oh wait, nm I was thinking dimmer when you said variac
[08:52:06] <Jymmm> ReadError: The issue with AC, is that it vibrates the hot wire =)
[08:52:06] <ReadError> ahh yea, with the dimmer you need a load I think
[08:52:26] <ReadError> yea I heard it buzzed, so far ive only used DC
[08:52:56] <Jymmm> cool
[08:54:00] <ReadError> was thinking about using a SSR and driving it using pwm
[08:54:17] <Jymmm> ReadError: And I can't tell you why, but even though it's the same wattage, altering the voltage can make a difference.
[08:54:29] <Jymmm> PWM = pulsing the wire =)
[08:55:25] <ReadError> if I use the transformer to go to DC that should solve it right?
[08:56:14] <Jymmm> mains -> variac -> xmfr -> bridge -> caps -> hotwire
[08:57:01] <Jymmm> You could use a ceilign fan dimmer if you want to go cheap at least for a test.
[08:57:21] <Jymmm> err ceiling fan speed control
[08:58:02] <Jymmm> I did see one digital heat control, but I haven't looked in a while
[08:59:46] <Jymmm> ReadError: Not sure if you are aware of this, but wattage is not the amount of het produced, but the ability to recover from heat lose in the cutting process and bringthe wire back up to the desired cutting temp as quickly as possible.
[09:01:52] <Jymmm> ReadError: Then, alter the feed speed to accomidate the cutting accuracy
[09:02:14] <Jymmm> ReadError: Hi/lo humidity can change settings too
[09:02:28] <Jymmm> ambiant temp, etc
[09:04:59] <Jymmm> ReadError: Could use a variac + car charger =)
[09:05:04] <ReadError> I got the variac already
[09:05:07] <Jymmm> a dumb one that is
[09:05:14] <ReadError> need to figure out the part after that though
[09:05:30] <Jymmm> just use a cheap car charger
[09:05:44] <Jymmm> or two of them
[09:07:38] <Jymmm> is series/parallel as you see fit
[09:08:22] <Jymmm> 24@2A, 12V@4A, etc
[09:10:13] <ReadError> http://www.amazon.com/Meanwell-Approved-Waterproof-Transformer-Warranty/dp/B00GIF45DY/
[09:10:20] <ReadError> would something like this work okay?
[09:10:43] <ReadError> hmm thats constant though
[09:10:48] <ReadError> dont know much at all about AC
[09:10:59] <Jymmm> No, those are always overrated for what they are.
[09:11:27] <Jymmm> and 2.5A is a lil low
[09:11:33] <Jymmm> imo
[09:12:02] <Jymmm> You could use a PC PS, they have 12v, 5v, and 3.3v at high amperage
[09:15:29] <ReadError> I have a server PSU down there now
[09:15:43] <ReadError> was using a ESC + servo tester
[09:19:42] <Jymmm> ReadError: Honestly , it's just a hot wire, use what you got. Do use a xmfr for isolation, and could add a bridge easily enough
[09:20:08] <Jymmm> ReadError: Just keep an eye on the xfmr heat build up
[09:23:03] <Jymmm> ReadError: I made a 4ft bow w/o xmfr. it hummed and shocked the shit out of myself as I was barefoot and touching one end =)
[09:24:57] <Jymmm> ReadError: One thing I thought about is using those RC motor speed controls. they're high amperage
[09:25:53] <Jymmm> ReadError: Kinda like this
http://hobbyking.com/hobbyking/store/__58264__Flycolor_30_Amp_Multi_rotor_ESC_2_4S_with_BEC.html
[09:26:52] <Jymmm> ReadError: I have NFC if it'll actually work, just a thought
[09:31:16] <ReadError> http://www.amazon.com/Honeywell-AT140A1000-40Va-120V-Transformer/dp/B000K2EC7K/
[09:31:19] <ReadError> grabbed that
[09:31:35] <ReadError> http://www.amazon.com/gp/product/B00CQLL3G6/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1
[09:31:37] <Jymmm> 40Va is low
[09:32:02] <Jymmm> that might give you 34W
[09:32:08] <ReadError> hm
[09:32:15] <ReadError> trying to find something on amazon
[09:32:47] <Jymmm> Why? Just hit a flea market, yard sale, thrift store and scavanged something
[09:32:49] <Tom_itx> couple mosfets under pwm control
[09:34:15] <Tom_itx> Jymmm barefoot touching 110vac?
[09:34:16] <Tom_itx> :D
[09:34:52] <ReadError> not too much around here like that
[09:35:03] <Jymmm> Tom_itx: Eh, better than when I touched 400V due to not being isolated (not my fault, it was miswired)
[09:36:42] <Jymmm> ReadError: yu can find a cheap car charger?
[09:37:17] <ReadError> i have one here I can try
[09:37:35] <Jymmm> 12V @ 10A = 120W
[09:37:49] <ReadError> will lowering the AC voltage let me modulate the DC output?
[09:38:03] <Jymmm> if it's a linear charger, yes =)
[09:38:38] <Jymmm> if it's a smart charger, it might be a PITA
[09:39:24] <ReadError> it looks pretty dumb, theres a 3 pos switch and a voltage gauge
[09:39:38] <Jymmm> no reverse polarity protection?
[09:39:53] <ReadError> hm not that I know of
[09:39:59] <ReadError> would have to check though
[09:40:00] <Jymmm> Then try it
[09:40:28] <Jymmm> does it have a 10A setting?
[09:43:09] <ReadError> think it goes to 6A
[12:29:30] <koss> anyone used one of these? seems like a good price
http://www.amazon.com/exec/obidos/ASIN/B000CRE7Q4/fpv-20/
[12:42:20] <skunkworks> something similar came on my craftsman chop saw. worked weel
[12:42:21] <skunkworks> well
[12:44:56] <MrL> hey, in this page
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?UpdatingTo2.6 it tells me to add linuxcnc archive key to apt key ring but when i try obtain it the key server timesout, what to do?
[13:18:01] <ssi> jdh: the geminis do in fact use the encoders for commutation once they index
[13:18:08] <ssi> but it needs something for the first revolution
[14:22:46] <CaptHindsight> ssi: does DHALL just disable the generation of a HALL error and doesn't disable the need for HALL signals to the drive?
[14:23:54] <CaptHindsight> aligning the HALL sensors to the motor shaft requires a scope on the Parker AC servos
[15:00:53] <sivu> hmm i have some problem with pwmgen
[15:00:58] <sivu> it just doesn't output anything
[15:02:07] <sivu> loadrt pwmgen output_type=0
[15:02:07] <sivu> addf pwmgen.make-pulses base-thread
[15:02:07] <sivu> addf pwmgen.update servo-thread
[15:02:07] <sivu> net pwm-enable => pwmgen.0.enable
[15:02:07] <sivu> net blink-pwm <= pwmgen.0.pwm => classicladder.0.in-10
[15:02:09] <sivu> setp pwmgen.0.pwm-freq 2.0
[15:02:12] <sivu> sets pwm-enable true
[15:02:22] <sivu> output is always 0
[15:18:34] <pcw_home_> 0 output is probably expected unless pwmgen.0.value is set to something
[15:20:46] <sivu> crap, that was left out when i copied the lines
[15:21:10] <sivu> in the meantime i got this done with siggen
[16:42:53] <Deejay> gn8
[17:02:23] <XXCoder> so. much. wtf.
https://i.chzbgr.com/maxW500/5018498048/hAE2A06F3/
[17:06:59] <pcw_home_> track&field / non track&field ?
[17:38:41] <tjtr33> XXCoder,
http://thiswastv.files.wordpress.com/2013/02/basil_manuel_upstairs.png?w=300&h=229 stairs went from this floor to this floor in Fawlty Towers
[19:19:08] <ssi> CaptHindsight: yeah I'm pretty sure there needs to be a hall signal in order to get them moving until it picks up the encoder index
[19:33:01] <jdh> DIY hall
[19:36:28] <ssi> jdh:
http://pico-systems.com/osc2.5/catalog/product_info.php?products_id=8
[19:36:34] <ssi> I'm going to build my own version of that
[19:36:45] <ssi> because I flat refuse to give him $450 for $10 worth of CPLDs
[19:56:12] <Connor> ssi, Wouldn't it be easier to just sell those servo's and buy new ones ?
[19:56:26] <ssi> maybe, maybe not
[19:56:45] <Connor> Looks like a complete pain in the ass to have to deal with.
[19:56:45] <ssi> I still haven't seen a replacement servo for sale
[19:56:49] <ssi> so I have no idea how much it'll cost
[19:56:56] <ssi> and no, it's not that much of a pain in the ass to have to deal with
[19:57:12] <ssi> it's a pain in the ass that someone's already solved this problem but prices it unrealistically
[19:57:16] <ssi> so I have to duplicate the effort
[19:57:34] <ssi> but it'll take me a day to lay out the board, I can build a hundred of them for less than he charges for one
[19:57:48] <ssi> and it'll take a day or two of experimentation to get the firmware right
[19:58:50] <Connor> I wonder why Fanuc decided to make the servo's like that...
[19:59:03] <ssi> to lock you into their drives
[20:00:21] <Connor> Been in the shop reworking the wiring in my enclosure..
[20:00:36] <Connor> prepping for the 5i25/7i76 install. :)
[20:01:12] <ssi> get it done
[20:01:16] <ssi> I got the vmc powered up today
[20:01:22] <ssi> it'll power up on single phase
[20:01:33] <ssi> but the servo drives require 185V 3phase, which comes from the autotransformer
[20:01:39] <ssi> so it comes up with a servo drive fault
[20:01:55] <Connor> and no 3 phase at the hanger right ?
[20:01:59] <ssi> correct
[20:02:07] <ssi> I got power pulled to it
[20:02:13] <ssi> all 6/3 on a 60a breaker
[20:02:22] <ssi> which is a bit small, but it'll have to do
[20:02:26] <Connor> you having 3 phase installed ?
[20:02:29] <ssi> no
[20:02:44] <ssi> vfds for the spindle and coolant pump, everything else will run on 1ph
[20:04:18] <Connor> So your going to have to get a phase converter?
[20:04:50] <Connor> Guess that depends on you keeping those servos...
[20:05:41] <ssi> um
[20:05:44] <ssi> vfds for the spindle and coolant pump, everything else will run on 1ph
[20:05:53] <ssi> means no 3 phase
[20:05:55] <ssi> no converter
[20:06:06] <Connor> VFDS can be 1 or 3 phase. :)
[20:06:12] <Connor> But. Okay.
[20:06:23] <ssi> vfds can all run on 1ph
[20:06:40] <ssi> pete's running his 15hp vfd on 1ph
[20:06:46] <Connor> Yes. I know.
[20:06:52] <Connor> But, you can also run them on 3 phase.
[20:06:56] <Connor> never mind...
[20:07:15] <ssi> why would I buy a $1500 phase converter just because you CAN run them on 3ph?
[20:14:50] <zeeshan> ssi
[20:14:56] <zeeshan> it'd prolly be cheaper to change the pump motor to 1 phase
[20:14:59] <zeeshan> instead of run vfd
[20:15:11] <zeeshan> you can scavenge 1 ph motors pretty cheaply
[20:20:23] <Tom_itx> ssi, 3 phase is cheaper for production machines but if you're not doing that it may not be practical
[20:26:21] <pcw_home_> Almost all encoders of newer drives are proprietary (there are at least 4 different serial encoder protocols)
[20:28:17] <pcw_home_> at least the 4 bit Fanuc commutation info is straightforward
[20:33:47] <ssi> pcw_home_: I'm gonna start laying out a board tonight or tomorrow
[20:33:58] <ssi> everyone keeps trying to talk me out of it but I think it's gonna be pretty straightforward
[20:34:10] <ssi> I think they're just jealous of my mad hacker skills :D
[20:34:20] <ssi> zeeshan: I have VFDs on hand
[20:34:33] <ssi> zeeshan: I have a 1/4hp one which might be a bit too small for the coolant pump
[20:34:45] <ssi> pump motor is labeled 290W, and the VFD is 200W
[20:35:10] <ssi> and it's an integrated gusher pump, so changing the motor likely isn't trivial
[20:35:12] <zeeshan> i have a brand new in package 0.5 hp eaton nvx series vfd
[20:35:14] <zeeshan> i need a 1hp
[20:35:18] <zeeshan> for my other drill press
[20:35:20] <zeeshan> hook me up
[20:35:21] <zeeshan> :-)
[20:35:22] <zeeshan> trADE??!
[20:35:51] <ssi> the only 1hp I have on hand is on the g0602
[20:36:07] <zeeshan> aw
[20:36:17] <ssi> how much you want for the 1/2hp?
[20:37:20] <zeeshan> honestly, keeping it for a trade
[20:37:21] <zeeshan> for 1hp
[20:37:22] <ssi> I paid like $30 for these 1/4hp vfds
[20:37:31] <ssi> I bought one for the coolant pump on the HNC, which is a 1/8hp motor
[20:37:35] <ssi> and it was so cheap, I bought a spare
[20:38:55] <zeeshan> now i know
[20:39:00] <zeeshan> why i accidently bought the 0.5 hp
[20:39:02] <zeeshan> when i was working there
[20:39:04] <zeeshan> its a 110V input
[20:39:11] <zeeshan> i didnt wanna run 240V
[20:39:14] <zeeshan> to the drill press
[20:39:43] <zeeshan> id be happy getting $140 for it
[20:39:49] <zeeshan> http://ca-en.alliedelec.com/search/productdetail.aspx?SKU=70056991
[20:39:50] <zeeshan> its this one
[20:49:37] <LatheBuilder> good evening
[20:51:27] <LatheBuilder> hi PetefromTn_
[20:51:50] <PetefromTn_> hello
[20:52:26] <PetefromTn_> whats goin' on in the linuxCNC world today hehe
[20:53:55] * LeelooMinai discovered today that making square holes in industrial polycarbonate enclosures sucks
[20:54:26] <LatheBuilder> I just joined the room tonight. Sorted out some of my machine startup troubles.
[20:54:42] <LatheBuilder> how did you end up cutting them?
[20:55:03] <LeelooMinai> I made holes in corners then use Proxxon with tiny diamond blades:)
[20:55:22] <LeelooMinai> I needded a hole fore mesa db-25 connector
[20:55:27] <PetefromTn_> they needed to be perfect squares then..
[20:55:55] <LeelooMinai> It ended up to be fine, but that stuff is pretty tough
[20:56:14] <LeelooMinai> Drills great though
[20:57:13] <pcw_home_> looks like 4 bit Gray code table lookup will have a 50% chance of 0 error or +-7.5 degree error
[20:59:59] <LeelooMinai> https://www.flickr.com/photos/100017731@N03/15450801801/ <- This will be by cnc electronics box
[21:00:40] <LeelooMinai> Only I will need to devise some circulation for it
[21:00:46] <pcw_home_> (7.5 degrees commutation angle error is insignificant)
[21:01:39] <LeelooMinai> Maybe make big round holes and put some air-filter-like material on the inside
[21:04:52] <zeeshan> LeelooMinai:
[21:05:12] <zeeshan> how about drilling a hole
[21:05:15] <zeeshan> then filing away the square? :P
[21:05:32] <zeeshan> polycarb is a pretty soft material so it doesnt take much force
[21:05:54] <LeelooMinai> zeeshan: DB-25 is not exactly square, you know:)
[21:06:10] <zeeshan> yes
[21:06:19] <zeeshan> laying it out
[21:06:21] <zeeshan> and filing :D
[21:06:43] <LeelooMinai> I made 4 holes in the corner, then cut along them with thin 5cm diamond blade, then used a file, yes
[21:06:43] <zeeshan> LeelooMinai: back in the day when i didnt have fancy equipment
[21:06:50] <zeeshan> and i had to make a 2.5" hole in stainless steel tubing
[21:07:02] <zeeshan> i used your method
[21:07:03] <Tom_itx> i've filed a few and cnc'd a few
[21:07:06] <zeeshan> drill a crap load of holes!
[21:07:26] <zeeshan> now its just plasma cut or hole saw
[21:07:37] <zeeshan> or mill it away :D
[21:07:54] <LeelooMinai> Well, I would not say it's "soft" - I tried to make cuts on it with a cutter, and it was not that easy
[21:08:04] <LeelooMinai> And i think they make bullet-proof glass from it:)
[21:09:19] <LeelooMinai> I guess the most advantage of having those enclosures made from it, that it's almost impossible to just smash something to it and make it crack, like normal plastic
[21:10:01] <zeeshan> my rear window on the rx7
[21:10:04] <zeeshan> is made out of lexan
[21:10:05] <zeeshan> polycarb
[21:10:13] <zeeshan> it works really well
[21:10:18] <zeeshan> i wish it didnt scratch as easy
[21:10:45] <LeelooMinai> I picked it up in some store that sells old stuff and it was $30, but I looked it up and they used to sell those for $250 - pretty crazy for such small box
[21:11:10] <zeeshan> for how big of a piece
[21:11:12] <LeelooMinai> Yes, well, it scratches easier than glass
[21:11:24] <LeelooMinai> Just 30x40x15cm like on the picture
[21:11:38] <Tom_itx> is that deep enough to fit everything?
[21:11:49] <LeelooMinai> Just the right size to stuff it with psu, 3x stepper drivers, some relay and that mesa card
[21:12:18] <LeelooMinai> Yes, I already played with arrangement and everything will fit nice
[21:12:29] <Tom_itx> and get rid of the heat generated?
[21:12:35] <LeelooMinai> Had to buy alu plate though to put as the base to fix everythin
[21:12:43] <zeeshan> im ghetto
[21:12:46] <zeeshan> mine went right into the box
[21:12:49] <zeeshan> without the mounting plate ;d
[21:12:59] <LeelooMinai> The alu plate will act as a nice radiator, but I will make some big ventilation holes on the sides
[21:13:15] <Tom_itx> i used the plate on mine but wish i'd have used din rails
[21:13:23] <zeeshan> i did use din rails
[21:13:29] <zeeshan> only for the fuse holders though
[21:13:39] <LeelooMinai> I aactually bought din adapter for the mesa card, but since I have the plate, I will not use it
[21:13:52] <zeeshan> are you using standoffs
[21:13:55] <zeeshan> for the mesa board
[21:14:06] <LeelooMinai> Yes, I will have standoffs on the plate
[21:14:15] <LeelooMinai> Just normal ones like in motherboards
[21:14:24] <zeeshan> ah
[21:14:43] <LeelooMinai> Tomorrow I will be drilling and tapping them I think
[21:14:44] <Tom_itx> http://tom-itx.ddns01.com:81/~webpage/cnc/psu/control8.jpg
[21:15:12] <zeeshan> whats up wit hthe big ass tranformers
[21:15:12] <zeeshan> :D
[21:15:14] <Tom_itx> mostly used or surplus
[21:15:14] <LeelooMinai> Hmm... what are those 3 transformers?
[21:15:28] <Tom_itx> 48v 18A
[21:15:41] <Tom_itx> no torroid
[21:15:41] <zeeshan> where be the drives
[21:15:51] <Tom_itx> behind the heatsink in the door
[21:15:55] <zeeshan> ah
[21:15:58] <Tom_itx> just ^^ up there
[21:16:03] <zeeshan> you guys are all fancy
[21:16:11] <zeeshan> with your seperate boxes for computer, steppers
[21:16:14] <Tom_itx> i got that enclosure cheap
[21:16:20] <zeeshan> i shoved all that crap in one place
[21:16:21] <zeeshan> :P
[21:16:27] <LeelooMinai> Tom_itx: So ho have the fan, but where is the hole for the air to come in? :)
[21:16:31] <Tom_itx> zeeshan no separate box... i have a sherline
[21:16:38] <zeeshan> oh
[21:16:42] <Tom_itx> LeelooMinai in the bottom
[21:16:50] <LeelooMinai> Under tha plate?
[21:17:13] <Tom_itx> the bottom has holes in it
[21:17:13] <LeelooMinai> Hmm, I guess that's not a bad idea
[21:17:25] <Tom_itx> comes up across the transformers and out
[21:17:35] <LeelooMinai> Maybe I will go this way too
[21:17:57] <Tom_itx> i put some risers on the box so it will circulate
[21:18:15] <zeeshan> where did you buy that wire loom
[21:18:16] <zeeshan> blue one
[21:18:20] <zeeshan> i need that for my car harness
[21:18:30] <Tom_itx> local surplus
[21:18:34] <LeelooMinai> Right, my box had already 4 standoff in the corners to mount the plate
[21:19:39] <LeelooMinai> I should probably buy some loom like that - don't have any
[21:19:58] <zeeshan> http://images.palcdn.com/hlr-system/WebPhotos/82/820/8209/8209264.jpg?_v=5a94e708-b43a-47fc-b9d2-56110847a5a6
[21:20:02] <zeeshan> its a lot better than this crap
[21:20:07] <LeelooMinai> I wonder if they make one that shrinks under temp
[21:20:19] <gammax> Hey everyone
[21:20:30] <CaptHindsight> LeelooMinai:
https://www.flickr.com/photos/100017731@N03/14239031355/in/photostream/ I like your indicator lamp. No tiny led's for you!
[21:20:41] <zeeshan> Tom_itx: does your loom split
[21:21:12] <LeelooMinai> CaptHindsight: lol, that was to test the board that has triac on to control some mains devices:)
[21:21:17] <Tom_itx> you could poke wires out the side if you need to
[21:21:23] <gammax> Been a long time since being hear! But good news! Buying a house and it has a 2 car garage! :D All my machinery ( currently in a 24ft box truck) Is getting setup in there! Also have plans on buying a vmc under 10k in a year or so.
[21:21:26] <zeeshan> ah cool
[21:21:30] <Tom_itx> i didn't plan to
[21:21:59] <zeeshan> damn LeelooMinai
[21:22:04] <LeelooMinai> CaptHindsight: Bit note my MacGyver ffc-connector from a clamp:)
[21:22:08] <zeeshan> im jealous. you has a nice xscope
[21:22:38] <LeelooMinai> zeeshan: I am poor and that scope is the famous entry level scope for poor hobbyists
[21:22:46] <zeeshan> its digital
[21:22:48] <zeeshan> 2 channel
[21:22:51] <zeeshan> and like 150 mhz
[21:22:54] <zeeshan> good enough for what i need!
[21:22:58] <LeelooMinai> You can buy it for $300+ or so
[21:23:04] <Tom_itx> LeelooMinai i've got a similar light :D
[21:23:09] <LeelooMinai> And mod it to be 100MHz with simple firmware hack
[21:23:33] <zeeshan> so you make it basically into the other model they have
[21:23:34] <Tom_itx> http://tom-itx.ddns01.com:81/~webpage/toaster_oven/blinktest2.jpg
[21:23:35] <zeeshan> the 100mhz one?
[21:23:37] <LeelooMinai> But they have new model now with 4 channels, also pretty good price
[21:23:37] <Tom_itx> for my toaster oven
[21:23:58] <gammax> You talking about the o scope?
[21:24:14] <LeelooMinai> Tom_itx: For reflow?
[21:24:21] <zeeshan> gammax: yes
[21:24:54] <gammax> I bought the sds7102
[21:24:57] <Tom_itx> LeelooMinai yes
[21:25:03] <gammax> Wanted to have warranty and bigger screen
[21:25:20] <gammax> 400 bucks out the door a year ago
[21:25:59] <zeeshan> i cant bring myself to spend that much on a tool ill rarely use
[21:26:01] <LeelooMinai> Tom_itx: I made one of those few years ago too (reflow controlers,) when I was learning ee:
http://imgur.com/7xDGY
[21:26:07] <zeeshan> i mostly need it for diagnoising car problems
[21:26:15] <zeeshan> diagnosing
[21:26:17] <LeelooMinai> Tom_itx:
http://imgur.com/JlXZW
[21:26:25] <LeelooMinai> Hacked some nokia display for it:)
[21:26:37] <zeeshan> LeelooMinai: are you in school for EE?
[21:26:41] <zeeshan> or hobby
[21:26:41] <gammax> zeeshan, well you can use the computer based one for easy stuff.... I think it uses sound card.
[21:26:54] <LeelooMinai> No, I am, hmm... I guess "retired programmer"
[21:27:06] <gammax> LeelooMinai: thats awsome!
[21:27:06] <zeeshan> gammax: portable is important
[21:27:08] <Tom_itx> LeelooMinai, nice.. all i've got is an lcd
[21:27:08] <LeelooMinai> EE is just my hobby, and I made CNC too when I was at it
[21:27:19] <zeeshan> LeelooMinai: cool
[21:27:31] <Tom_itx> http://tom-itx.ddns01.com:81/~webpage/toaster_oven/toaster_oven_index.php
[21:27:37] <Tom_itx> there's the whole project
[21:27:49] <LeelooMinai> I needed something more tangible then programming, but I still program a lot (for my microcontroller projects)
[21:28:12] <zeeshan> programmers make good money :P
[21:28:50] <LeelooMinai> Tom_itx: I see you put that insulation stuff into your oven - I did that too: stole some from basement walls:)
[21:29:38] <LeelooMinai> It sheds tiny glass fibers though
[21:29:42] <gammax> Tom_itx: have any extra control boards? :D Would love to make one!
[21:30:08] <Tom_itx> that's one i didn't send off.. i homebrewed it
[21:30:17] <Tom_itx> i doubt i have another good one
[21:30:38] <Tom_itx> the schematic is there i think
[21:30:56] <gammax> That a pic on there?
[21:31:06] <Tom_itx> atmega168
[21:31:18] <Tom_itx> 48 or 88 would be big enough
[21:31:30] <Tom_itx> oh and the lcd has a 2313 behind it for serial lcd
[21:31:35] <gammax> program up there aswell?
[21:32:10] <Tom_itx> it may be there somewhere
[21:32:33] <Tom_itx> alot of guys use thermocouples
[21:32:39] <Tom_itx> i used a PT100 sensor
[21:32:55] <LeelooMinai> Is't that thermocouple too, just platinum one?
[21:33:02] <Tom_itx> for that it's linear enough just to use the internal 1.1v reference
[21:33:10] <Tom_itx> i suppose
[21:33:24] <LeelooMinai> I just used cheap k type - works fine for those temps
[21:34:57] <Tom_itx> i don't do ROHS with it but i suppose it could
[21:35:07] <gammax> Tom_itx: you getting involved in the multi purpose Pick and place machine development?
[21:35:12] <Tom_itx> i didn't write the profile for that
[21:35:20] <Tom_itx> no
[21:36:25] <gammax> http://hackaday.io/project/963-%24300-Pick-and-Place-%2F-3D-printer
[21:37:14] <tjtr33> or
http://firepick1.github.io/ some talk about it recently on these chats
[21:37:21] <gammax> There almost done with major development but looking for coders if you can help! Will be a solder paste applicator, pick n place, 3d printer and something else.
[21:37:45] <gammax> yeah they need help programming some of the motion stuff.
[21:37:56] <gammax> was gonna see if anyone wanted to help out
[21:38:28] <tjtr33> i am wrestling with matrix math now, not good enuf to lead others ;)
[21:38:34] <Tom_itx> at one point i was gonna make a delta pick n place but i probably don't need it now
[21:38:48] <gammax> lol
[21:39:00] <gammax> they need help with motion and the camera for detection.
[21:39:15] <gammax> My next goal after that project will be getting a 3d scanner for projects.
[21:40:30] <gammax> and also converting my hardinge lathe mate into linuxcnc
[21:41:14] <PetefromTn_> does your hardinge have leadscrews?
[21:42:46] <gammax> ball
[21:43:34] <gammax> Thankfully!
[21:45:28] <LatheBuilder> are estop contactors normally run with latching circuits and started with a few second long pulse?
[21:46:29] <PetefromTn_> my estop is wired into a latching circuit that also has the limits and whatnot all hooked up to it. Servo enable latches it and any of the former open it.
[21:47:29] <LatheBuilder> that must be what I am missing. Is servo enable out of a Mesa 7i77 only a 1 - 3 second long pulse?
[21:48:31] <PetefromTn_> I don't understand the question it is instantaneous on mine.. just press the button and servos are enabled.
[21:49:06] <LatheBuilder> rethinking my question. servo enable shouldn't be, but estop out is perhaps...off to check
[21:50:15] <gammax> Im in search of a mesa cards if anyone knows of some for sale! :D
[21:50:28] <LatheBuilder> when i power up my drives they come to life for a second or two and then drop. I am definitely missing something with the estop circuit.
[21:50:59] <gammax> lathe, what kind of drives are they?
[21:51:03] <gammax> LatheBuilder: ^^
[21:51:28] <LatheBuilder> dc servos, +/- 10VDC. Servo dynamics
[21:52:03] <gammax> can you give a model?
[21:52:16] <gammax> maby they need more than a momentary pulse
[21:52:54] <LatheBuilder> my machine came from a boutique builder back in the late 80's. the servo drive itself isn't the problem.
[21:53:04] <PetefromTn_> are they faulting when they enable and then shutting down?
[21:54:03] <LatheBuilder> I have a bank of contactors. One double contactor pair to run the estop circuit, one single large one (mcc) with overloads to feed the spindle vfd.
[21:55:09] <LatheBuilder> working through how it is meant to run. (not my area of expertise, learning as I go).
[21:55:33] <gammax> LatheBuilder: any sites with photos/write ups on it?
[21:56:09] <LatheBuilder> Manually triggering the master control contactor powers up all the drives, vfd included.
[21:56:46] <LatheBuilder> no
[21:58:43] <LatheBuilder> main question is this: machine tools usually only have 1) estop circuit enabled - meaning concactors latched, ready for next action and
[21:58:49] <tjtr33> http://www.mesanet.com/pdf/parallel/7i77man.pdf page 14, looks like enable is level not pulse
[22:00:35] <LatheBuilder> 2) drive enable, including servo amp and vfd
[22:02:45] <LatheBuilder> tjtr33>> ya, that's the odd bit. I must not be latching the estop contactors prior to drive enable
[22:02:56] <tjtr33> http://www.vdwalle.com/Norte/An%20Emergency%20Stop%20Circuit%20with%20EMC2.htm and a text only vrsn of the mazak solution
http://wiki.linuxcnc.org/cgi-bin/wiki.pl?MazakEstopChain
[22:03:31] <tjtr33> the first shows the basic latch wiring ( not linuxcnc at all, just relay logic )
[22:04:20] <LatheBuilder> Thanks! printing it out and walking out to the shop to trace the estop coil circuit
[22:04:24] <tjtr33> and a couple hundred millisecs is plenty, a firm push of button, a tap might fail to register
[22:57:23] <LatheBuilder> good news. my control schematic lied about what pin the estop relay was tied to. That's fixed now.
[22:58:51] <gammax> LatheBuilder: Glad to hear it!
[22:58:54] <PetefromTn_> always nice to get good news
[22:59:03] <LatheBuilder> now to trace the rest of the estop and enable circuit.
[22:59:18] <ssi> finally home
[22:59:36] <ssi> first time I've been home really since wednesday morning :P
[23:00:21] <LatheBuilder> there are more dependencies I do not understand yet. Concept yes, actual implementation in this control, no.
[23:00:28] <LatheBuilder> welcome home ssi
[23:03:16] <LatheBuilder> the machine builder did many things differently than dynapath suggested it seems. Now I start from a cleaner slate knowing that potentially most of the pinout is wrong...probably a better place to start from to get familiar
[23:03:50] <LatheBuilder> g'nite!
[23:04:05] <PetefromTn_> gn8 lathe
[23:04:19] <LatheBuilder> and thanks for suggestions
[23:04:30] <LatheBuilder> nite pete
[23:16:03] <ssi> PetefromTn_: how goes it
[23:16:49] <PetefromTn_> fine just sitting here working on a CAD drawing you>
[23:17:04] <ssi> just trying to get settled
[23:17:05] <ssi> heh
[23:17:18] <PetefromTn_> cool
[23:17:32] <PetefromTn_> my kids are off for fall break all this week
[23:18:03] <PetefromTn_> so I will be working in the shop but trying to entertain them a bit too
[23:19:53] <PetefromTn_> watching Galaxy Quest on Netflix... LOL I never realized Sigourney Weaver was such a babe hehe
[23:19:58] <ssi> heheh
[23:31:06] <tjtr33> nite all
[23:31:15] <PetefromTn_> Gnite
