[00:17:14] <ssi> I'm going to build my own version of that

[00:36:52] <Connor> ssi, Wouldn't it be easier to just sell those servo's and buy new ones ?
[00:37:06] <ssi> maybe, maybe not
[00:37:25] <Connor> Looks like a complete pain in the ass to have to deal with.
[00:37:25] <ssi> I still haven't seen a replacement servo for sale
[00:37:29] <ssi> so I have no idea how much it'll cost
[00:37:36] <ssi> and no, it's not that much of a pain in the ass to have to deal with
[00:37:52] <ssi> it's a pain in the ass that someone's already solved this problem but prices it unrealistically
[00:37:56] <ssi> so I have to duplicate the effort
[00:38:14] <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
[00:38:28] <ssi> and it'll take a day or two of experimentation to get the firmware right
[00:38:52] -!- tronwizard [tronwizard!~tronwizar@24.229.167.126.res-cmts.sm.ptd.net] has joined #linuxcnc
[00:39:30] <Connor> I wonder why Fanuc decided to make the servo's like that...
[00:39:43] <ssi> to lock you into their drives
[00:41:01] <Connor> Been in the shop reworking the wiring in my enclosure..
[00:41:16] <Connor> prepping for the 5i25/7i76 install. :)
[00:41:52] <ssi> get it done
[00:41:56] <ssi> I got the vmc powered up today
[00:42:02] <ssi> it'll power up on single phase
[00:42:13] <ssi> but the servo drives require 185V 3phase, which comes from the autotransformer
[00:42:19] <ssi> so it comes up with a servo drive fault
[00:42:35] <Connor> and no 3 phase at the hanger right ?
[00:42:39] <ssi> correct
[00:42:47] <ssi> I got power pulled to it
[00:42:53] <ssi> all 6/3 on a 60a breaker
[00:43:03] <ssi> which is a bit small, but it'll have to do
[00:43:06] <Connor> you having 3 phase installed ?
[00:43:09] <ssi> no
[00:43:24] <ssi> vfds for the spindle and coolant pump, everything else will run on 1ph
[00:44:58] <Connor> So your going to have to get a phase converter?
[00:45:30] <Connor> Guess that depends on you keeping those servos...
[00:46:21] <ssi> um
[00:46:24] <ssi> vfds for the spindle and coolant pump, everything else will run on 1ph
[00:46:33] <ssi> means no 3 phase
[00:46:35] <ssi> no converter
[00:46:46] <Connor> VFDS can be 1 or 3 phase. :)
[00:46:52] <Connor> But. Okay.
[00:47:03] <ssi> vfds can all run on 1ph
[00:47:20] <ssi> pete's running his 15hp vfd on 1ph
[00:47:26] <Connor> Yes. I know.
[00:47:32] <Connor> But, you can also run them on 3 phase.
[00:47:36] <Connor> never mind...
[00:47:55] <ssi> why would I buy a $1500 phase converter just because you CAN run them on 3ph?

[00:55:30] <zeeshan> ssi
[00:55:36] <zeeshan> it'd prolly be cheaper to change the pump motor to 1 phase
[00:55:39] <zeeshan> instead of run vfd
[00:55:51] <zeeshan> you can scavenge 1 ph motors pretty cheaply

[01:01:03] <Tom_itx> ssi, 3 phase is cheaper for production machines but if you're not doing that it may not be practical
[01:07:01] <pcw_home_> Almost all encoders of newer drives are proprietary (there are at least 4 different serial encoder protocols)

[01:14:27] <ssi> pcw_home_: I'm gonna start laying out a board tonight or tomorrow
[01:14:38] <ssi> everyone keeps trying to talk me out of it but I think it's gonna be pretty straightforward
[01:14:50] <ssi> I think they're just jealous of my mad hacker skills :D

[01:15:00] <ssi> zeeshan: I have VFDs on hand
[01:15:13] <ssi> zeeshan: I have a 1/4hp one which might be a bit too small for the coolant pump
[01:15:25] <ssi> pump motor is labeled 290W, and the VFD is 200W
[01:15:50] <ssi> and it's an integrated gusher pump, so changing the motor likely isn't trivial
[01:15:52] <zeeshan> i have a brand new in package 0.5 hp eaton nvx series vfd
[01:15:53] <zeeshan> i need a 1hp
[01:15:58] <zeeshan> for my other drill press
[01:16:00] <zeeshan> hook me up
[01:16:01] <zeeshan> :-)
[01:16:02] <zeeshan> trADE??!
[01:16:32] <ssi> the only 1hp I have on hand is on the g0602
[01:16:47] <zeeshan> aw
[01:16:57] <ssi> how much you want for the 1/2hp?
[01:18:00] <zeeshan> honestly, keeping it for a trade
[01:18:01] <zeeshan> for 1hp
[01:18:02] <ssi> I paid like $30 for these 1/4hp vfds
[01:18:11] <ssi> I bought one for the coolant pump on the HNC, which is a 1/8hp motor
[01:18:15] <ssi> and it was so cheap, I bought a spare
[01:19:35] <zeeshan> now i know
[01:19:40] <zeeshan> why i accidently bought the 0.5 hp
[01:19:42] <zeeshan> when i was working there
[01:19:44] <zeeshan> its a 110V input
[01:19:51] <zeeshan> i didnt wanna run 240V
[01:19:54] <zeeshan> to the drill press
[01:20:23] <zeeshan> id be happy getting $140 for it

[01:32:13] -!- elmo40 has quit [Ping timeout: 272 seconds]
[01:32:30] <PetefromTn_> hello
[01:33:06] <PetefromTn_> whats goin' on in the linuxCNC world today hehe
[01:34:35] * LeelooMinai discovered today that making square holes in industrial polycarbonate enclosures sucks
[01:34:39] -!- anth0ny has quit [Client Quit]
[01:35:06] <LatheBuilder> I just joined the room tonight. Sorted out some of my machine startup troubles.
[01:35:22] <LatheBuilder> how did you end up cutting them?
[01:35:43] <LeelooMinai> I made holes in corners then use Proxxon with tiny diamond blades:)
[01:36:02] <LeelooMinai> I needded a hole fore mesa db-25 connector
[01:36:07] <PetefromTn_> they needed to be perfect squares then..
[01:36:35] <LeelooMinai> It ended up to be fine, but that stuff is pretty tough
[01:36:54] <LeelooMinai> Drills great though
[01:37:53] <pcw_home_> looks like 4 bit Gray code table lookup will have a 50% chance of 0 error or +-7.5 degree error
[01:40:39] <LeelooMinai> https://www.flickr.com/photos/100017731@N03/15450801801/ <- This will be by cnc electronics box
[01:41:20] <LeelooMinai> Only I will need to devise some circulation for it
[01:41:26] <pcw_home_> (7.5 degrees commutation angle error is insignificant)
[01:42:19] <LeelooMinai> Maybe make big round holes and put some air-filter-like material on the inside
[01:45:32] <zeeshan> LeelooMinai:
[01:45:52] <zeeshan> how about drilling a hole
[01:45:55] <zeeshan> then filing away the square? :P
[01:46:12] <zeeshan> polycarb is a pretty soft material so it doesnt take much force
[01:46:34] <LeelooMinai> zeeshan: DB-25 is not exactly square, you know:)
[01:46:50] <zeeshan> yes
[01:46:59] <zeeshan> laying it out
[01:47:01] <zeeshan> and filing :D
[01:47:23] <LeelooMinai> I made 4 holes in the corner, then cut along them with thin 5cm diamond blade, then used a file, yes
[01:47:23] <zeeshan> LeelooMinai: back in the day when i didnt have fancy equipment
[01:47:30] <zeeshan> and i had to make a 2.5" hole in stainless steel tubing
[01:47:42] <zeeshan> i used your method
[01:47:43] <Tom_itx> i've filed a few and cnc'd a few
[01:47:46] <zeeshan> drill a crap load of holes!
[01:48:06] <zeeshan> now its just plasma cut or hole saw
[01:48:17] <zeeshan> or mill it away :D
[01:48:34] <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
[01:48:45] <LeelooMinai> And i think they make bullet-proof glass from it:)
[01:49:59] <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
[01:50:41] <zeeshan> my rear window on the rx7
[01:50:44] <zeeshan> is made out of lexan
[01:50:45] <zeeshan> polycarb
[01:50:53] <zeeshan> it works really well
[01:50:58] <zeeshan> i wish it didnt scratch as easy
[01:51:25] <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
[01:51:50] <zeeshan> for how big of a piece
[01:51:52] <LeelooMinai> Yes, well, it scratches easier than glass
[01:52:04] <LeelooMinai> Just 30x40x15cm like on the picture
[01:52:18] <Tom_itx> is that deep enough to fit everything?
[01:52:29] <LeelooMinai> Just the right size to stuff it with psu, 3x stepper drivers, some relay and that mesa card
[01:52:58] <LeelooMinai> Yes, I already played with arrangement and everything will fit nice
[01:53:09] <Tom_itx> and get rid of the heat generated?
[01:53:15] <LeelooMinai> Had to buy alu plate though to put as the base to fix everythin
[01:53:23] <zeeshan> im ghetto
[01:53:26] <zeeshan> mine went right into the box
[01:53:29] <zeeshan> without the mounting plate ;d
[01:53:39] <LeelooMinai> The alu plate will act as a nice radiator, but I will make some big ventilation holes on the sides
[01:53:55] <Tom_itx> i used the plate on mine but wish i'd have used din rails
[01:54:03] <zeeshan> i did use din rails
[01:54:09] <zeeshan> only for the fuse holders though
[01:54:19] <LeelooMinai> I aactually bought din adapter for the mesa card, but since I have the plate, I will not use it
[01:54:32] <zeeshan> are you using standoffs
[01:54:35] <zeeshan> for the mesa board
[01:54:46] <LeelooMinai> Yes, I will have standoffs on the plate
[01:54:55] <LeelooMinai> Just normal ones like in motherboards
[01:55:04] <zeeshan> ah
[01:55:23] <LeelooMinai> Tomorrow I will be drilling and tapping them I think
[01:55:24] <Tom_itx> http://tom-itx.ddns01.com:81/~webpage/cnc/psu/control8.jpg
[01:55:52] <zeeshan> whats up wit hthe big ass tranformers
[01:55:52] <zeeshan> :D
[01:55:54] <Tom_itx> mostly used or surplus
[01:55:54] <LeelooMinai> Hmm... what are those 3 transformers?
[01:56:08] <Tom_itx> 48v 18A
[01:56:21] <Tom_itx> no torroid
[01:56:21] <zeeshan> where be the drives
[01:56:31] <Tom_itx> behind the heatsink in the door
[01:56:35] <zeeshan> ah
[01:56:38] <Tom_itx> just ^^ up there
[01:56:43] <zeeshan> you guys are all fancy
[01:56:51] <zeeshan> with your seperate boxes for computer, steppers
[01:56:54] <Tom_itx> i got that enclosure cheap
[01:57:00] <zeeshan> i shoved all that crap in one place
[01:57:01] <zeeshan> :P
[01:57:07] <LeelooMinai> Tom_itx: So ho have the fan, but where is the hole for the air to come in? :)
[01:57:11] <Tom_itx> zeeshan no separate box... i have a sherline
[01:57:18] <zeeshan> oh
[01:57:22] <Tom_itx> LeelooMinai in the bottom
[01:57:30] <LeelooMinai> Under tha plate?
[01:57:53] <Tom_itx> the bottom has holes in it
[01:57:53] <LeelooMinai> Hmm, I guess that's not a bad idea
[01:58:05] <Tom_itx> comes up across the transformers and out
[01:58:15] <LeelooMinai> Maybe I will go this way too
[01:58:37] <Tom_itx> i put some risers on the box so it will circulate
[01:58:55] <zeeshan> where did you buy that wire loom
[01:58:56] <zeeshan> blue one
[01:59:00] <zeeshan> i need that for my car harness
[01:59:10] <Tom_itx> local surplus
[01:59:14] <LeelooMinai> Right, my box had already 4 standoff in the corners to mount the plate
[02:00:19] <LeelooMinai> I should probably buy some loom like that - don't have any

[02:00:47] <LeelooMinai> I wonder if they make one that shrinks under temp
[02:00:59] <gammax> Hey everyone
[02:01:10] <CaptHindsight> LeelooMinai: https://www.flickr.com/photos/100017731@N03/14239031355/in/photostream/ I like your indicator lamp. No tiny led's for you!
[02:01:21] <zeeshan> Tom_itx: does your loom split
[02:01:52] <LeelooMinai> CaptHindsight: lol, that was to test the board that has triac on to control some mains devices:)
[02:01:57] <Tom_itx> you could poke wires out the side if you need to
[02:02:03] <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.
[02:02:06] <zeeshan> ah cool
[02:02:10] <Tom_itx> i didn't plan to
[02:02:39] <zeeshan> damn LeelooMinai
[02:02:44] <LeelooMinai> CaptHindsight: Bit note my MacGyver ffc-connector from a clamp:)
[02:02:48] <zeeshan> im jealous. you has a nice xscope
[02:03:18] <LeelooMinai> zeeshan: I am poor and that scope is the famous entry level scope for poor hobbyists
[02:03:26] <zeeshan> its digital
[02:03:28] <zeeshan> 2 channel
[02:03:31] <zeeshan> and like 150 mhz
[02:03:34] <zeeshan> good enough for what i need!
[02:03:38] <LeelooMinai> You can buy it for $300+ or so
[02:03:44] <Tom_itx> LeelooMinai i've got a similar light :D
[02:03:49] <LeelooMinai> And mod it to be 100MHz with simple firmware hack
[02:04:13] <zeeshan> so you make it basically into the other model they have
[02:04:14] <Tom_itx> http://tom-itx.ddns01.com:81/~webpage/toaster_oven/blinktest2.jpg
[02:04:15] <zeeshan> the 100mhz one?
[02:04:17] <LeelooMinai> But they have new model now with 4 channels, also pretty good price
[02:04:17] <Tom_itx> for my toaster oven
[02:04:38] <gammax> You talking about the o scope?
[02:04:54] <LeelooMinai> Tom_itx: For reflow?
[02:05:01] <zeeshan> gammax: yes
[02:05:34] <gammax> I bought the sds7102
[02:05:37] <Tom_itx> LeelooMinai yes
[02:05:43] <gammax> Wanted to have warranty and bigger screen
[02:06:00] <gammax> 400 bucks out the door a year ago
[02:06:39] <zeeshan> i cant bring myself to spend that much on a tool ill rarely use
[02:06:41] <LeelooMinai> Tom_itx: I made one of those few years ago too (reflow controlers,) when I was learning ee: http://imgur.com/7xDGY
[02:06:47] <zeeshan> i mostly need it for diagnoising car problems

[02:07:05] <LeelooMinai> Hacked some nokia display for it:)
[02:07:17] <zeeshan> LeelooMinai: are you in school for EE?
[02:07:21] <zeeshan> or hobby
[02:07:21] <gammax> zeeshan, well you can use the computer based one for easy stuff.... I think it uses sound card.
[02:07:34] <LeelooMinai> No, I am, hmm... I guess "retired programmer"
[02:07:46] <gammax> LeelooMinai: thats awsome!
[02:07:46] <zeeshan> gammax: portable is important
[02:07:48] <Tom_itx> LeelooMinai, nice.. all i've got is an lcd
[02:07:48] <LeelooMinai> EE is just my hobby, and I made CNC too when I was at it
[02:07:59] <zeeshan> LeelooMinai: cool
[02:08:11] <Tom_itx> http://tom-itx.ddns01.com:81/~webpage/toaster_oven/toaster_oven_index.php
[02:08:17] <Tom_itx> there's the whole project
[02:08:29] <LeelooMinai> I needed something more tangible then programming, but I still program a lot (for my microcontroller projects)
[02:08:53] <zeeshan> programmers make good money :P
[02:09:30] <LeelooMinai> Tom_itx: I see you put that insulation stuff into your oven - I did that too: stole some from basement walls:)
[02:10:18] <LeelooMinai> It sheds tiny glass fibers though
[02:10:22] <gammax> Tom_itx: have any extra control boards? :D Would love to make one!
[02:10:48] <Tom_itx> that's one i didn't send off.. i homebrewed it
[02:10:57] <Tom_itx> i doubt i have another good one
[02:11:18] <Tom_itx> the schematic is there i think
[02:11:36] <gammax> That a pic on there?
[02:11:46] <Tom_itx> atmega168
[02:11:58] <Tom_itx> 48 or 88 would be big enough
[02:12:10] <Tom_itx> oh and the lcd has a 2313 behind it for serial lcd
[02:12:15] <gammax> program up there aswell?
[02:12:50] <Tom_itx> it may be there somewhere
[02:13:13] <Tom_itx> alot of guys use thermocouples
[02:13:19] <Tom_itx> i used a PT100 sensor
[02:13:35] <LeelooMinai> Is't that thermocouple too, just platinum one?
[02:13:42] <Tom_itx> for that it's linear enough just to use the internal 1.1v reference
[02:13:50] <Tom_itx> i suppose
[02:14:04] <LeelooMinai> I just used cheap k type - works fine for those temps
[02:15:37] <Tom_itx> i don't do ROHS with it but i suppose it could
[02:15:47] <gammax> Tom_itx: you getting involved in the multi purpose Pick and place machine development?
[02:15:52] <Tom_itx> i didn't write the profile for that
[02:16:00] <Tom_itx> no
[02:17:05] <gammax> http://hackaday.io/project/963-%24300-Pick-and-Place-%2F-3D-printer
[02:17:54] <tjtr33> or http://firepick1.github.io/ some talk about it recently on these chats
[02:18:01] <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.
[02:18:25] <gammax> yeah they need help programming some of the motion stuff.
[02:18:36] <gammax> was gonna see if anyone wanted to help out
[02:19:08] <tjtr33> i am wrestling with matrix math now, not good enuf to lead others ;)
[02:19:14] <Tom_itx> at one point i was gonna make a delta pick n place but i probably don't need it now
[02:19:28] <gammax> lol
[02:19:40] <gammax> they need help with motion and the camera for detection.
[02:19:55] <gammax> My next goal after that project will be getting a 3d scanner for projects.
[02:21:10] <gammax> and also converting my hardinge lathe mate into linuxcnc
[02:21:54] <PetefromTn_> does your hardinge have leadscrews?
[02:23:26] <gammax> ball
[02:24:14] <gammax> Thankfully!
[02:26:08] <LatheBuilder> are estop contactors normally run with latching circuits and started with a few second long pulse?
[02:27:09] <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.
[02:28:09] <LatheBuilder> that must be what I am missing. Is servo enable out of a Mesa 7i77 only a 1 - 3 second long pulse?
[02:29:11] <PetefromTn_> I don't understand the question it is instantaneous on mine.. just press the button and servos are enabled.
[02:29:46] <LatheBuilder> rethinking my question. servo enable shouldn't be, but estop out is perhaps...off to check
[02:30:55] <gammax> Im in search of a mesa cards if anyone knows of some for sale! :D
[02:31:08] <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.
[02:31:39] <gammax> lathe, what kind of drives are they?
[02:31:43] <gammax> LatheBuilder: ^^
[02:32:08] <LatheBuilder> dc servos, +/- 10VDC. Servo dynamics
[02:32:43] <gammax> can you give a model?
[02:32:56] <gammax> maby they need more than a momentary pulse
[02:33:34] <LatheBuilder> my machine came from a boutique builder back in the late 80's. the servo drive itself isn't the problem.
[02:33:44] <PetefromTn_> are they faulting when they enable and then shutting down?
[02:34:43] <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.
[02:35:49] <LatheBuilder> working through how it is meant to run. (not my area of expertise, learning as I go).
[02:36:13] <gammax> LatheBuilder: any sites with photos/write ups on it?
[02:36:49] <LatheBuilder> Manually triggering the master control contactor powers up all the drives, vfd included.
[02:37:26] <LatheBuilder> no
[02:39:23] <LatheBuilder> main question is this: machine tools usually only have 1) estop circuit enabled - meaning concactors latched, ready for next action and
[02:39:29] <tjtr33> http://www.mesanet.com/pdf/parallel/7i77man.pdf page 14, looks like enable is level not pulse
[02:41:15] <LatheBuilder> 2) drive enable, including servo amp and vfd

[02:43:25] <LatheBuilder> tjtr33>> ya, that's the odd bit. I must not be latching the estop contactors prior to drive enable
[02:43:36] <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
[02:44:11] <tjtr33> the first shows the basic latch wiring ( not linuxcnc at all, just relay logic )
[02:45:00] <LatheBuilder> Thanks! printing it out and walking out to the shop to trace the estop coil circuit
[02:45:04] <tjtr33> and a couple hundred millisecs is plenty, a firm push of button, a tap might fail to register

[03:39:34] <PetefromTn_> always nice to get good news

[03:43:56] <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

[04:43:28] <ssi> weeee here we go
[04:43:51] <PetefromTn_> a little late for a party no hehe
[04:45:26] <ssi> yeah I'm screwy like that
[04:45:31] <ssi> at 11 I was dead tired
[04:45:36] <ssi> wanted nothing more than to get home and go to bed
[04:45:47] <ssi> now here I am, showered and fresh, and my mind is back in high gear
[04:46:28] <ssi> so here's what I think I can do, which'll be kinda awesome
[04:46:32] <PetefromTn_> I am kinda like that... I have always been a night person anyway. Sometimes I cannot sleep and stay up all night working on projects
[04:46:40] <ssi> my drives have those amp champ series II connectors on thew
[04:46:50] <ssi> theyr'e designed to be molded in cable plugs
[04:46:57] <ssi> and they're a bitch to solder
[04:47:03] <ssi> they make PCB mount versions
[04:47:29] <PetefromTn_> are you talking about that high density connector like on my drives
[04:47:29] <ssi> I think what I might do is design a PCB which carries the mating connectors
[04:47:32] <ssi> yeah
[04:47:42] <ssi> the PCB would snap onto the drive, and provide terminal blocks to wire to
[04:47:43] <ssi> AND
[04:47:48] <ssi> a cpld to do the fanuc conversion
[04:47:54] <ssi> all in one convenient package :)
[04:47:54] <PetefromTn_> They already make those.
[04:48:05] <PetefromTn_> oh yeah not with the fanuc part
[04:48:17] <ssi> right
[04:48:31] <ssi> and on the other side, I can put a D-sub connector
[04:48:37] <ssi> which mates directly to the cable coming from the motor
[04:49:13] <ssi> then the only thing I really need to be concerned about is mechanical security of that board
[04:53:24] -!- zeitue has quit [Ping timeout: 250 seconds]
[04:53:27] <PetefromTn_> sounds like a reasonable solution
[04:53:34] <ssi> yeah
[04:53:42] <ssi> a bit more crap to figure out in terms of mechanical fitment
[04:53:51] <ssi> but could be worthwhile to reduce the wiring headache
[04:54:20] <ssi> give me phoenix blocks and/or D-sub any day of the week
[04:54:29] <ssi> these amp champ connectors are not my favorite
[04:54:44] <ssi> not low-volume friendly
[04:54:52] <PetefromTn_> like I said when I was working on my drives I was in search of a breakout board to avoid doing that high density soldering on the cables and they had them available so I suppose it would work without alterior mechanical support
[04:55:06] <ssi> yeah maybe
[04:55:17] <ssi> I'll put some mounting holes on it, and if I need to build a bracket I will
[04:56:47] <PetefromTn_> after soldering them all up tho it was not as difficult as I had initially imagined really. Just a wire at a time
[04:56:56] <ssi> yeah it's not the end of the world
[04:59:21] <PetefromTn_> I finally crawled under my house today and moved the cable wire so we can put the cable modem and wireless router near my flatscreen. This allows me to plug the ethernet directly into the TV so we have all the onscreen options like netflix etc without having to load up the wifi on the blu ray player.
[05:00:09] <ssi> nice :)
[05:00:11] <ssi> http://www.digikey.com/product-detail/en/5175887-4/A115315-ND/2203262
[05:00:16] <ssi> PCB mount version of that connector
[05:00:19] <ssi> they're not inexpensive
[05:01:08] <PetefromTn_> they also had the kind you press into a flat cable too as I recall

[05:04:01] <PetefromTn_> have you figured out how you are going to install the PC and monitor?
[05:04:48] <ssi> no, not yet
[05:04:54] <ssi> I don't have the same nice pendant you do
[05:04:58] <ssi> mine's that stupid box
[05:05:06] <ssi> I may make a whole new pendant
[05:05:15] <PetefromTn_> yeah but it gives you lots of room
[05:05:28] <ssi> it's the wrong shape tho
[05:05:29] <PetefromTn_> you can do that too of course
[05:05:33] <ssi> short and deep
[05:06:03] <PetefromTn_> it would be cool to remove that whole thing and make something very tight to the front of the enclosure somehow.
[05:06:08] <ssi> yeah
[05:06:11] <ssi> I may put the PC in the back
[05:06:15] <ssi> and run vga/kb cables back
[05:06:39] -!- zeitue [zeitue!~z@67.221.138.10] has joined #linuxcnc
[05:06:44] <ssi> and for whatever front panel work I do, I'll get that mesa smart-serial pendant IO board
[05:06:59] <PetefromTn_> that would work too
[05:07:22] <ssi> that's not really a priority in my brain right now :)
[05:07:49] <ssi> priority goes: axes, spindle, operator station, toolchanger :D
[05:07:54] <PetefromTn_> thats funny it was one of the first things I did when I started.
[05:07:57] <ssi> yeah
[05:08:40] <PetefromTn_> It was kinda fun gutting the whole electronics cabinet...
[05:08:55] <PetefromTn_> You should have seen the huge pile of wires I tore out of there.
[05:09:05] <ssi> did you leave the transformers in the back? I forget
[05:09:15] <ssi> I don't think I really need them for anything
[05:09:19] <ssi> other than maybe making 110V
[05:09:29] <PetefromTn_> The main transformer is still underneath the cabinet but It does not get used anymore
[05:09:35] <ssi> mine are top left
[05:09:37] <ssi> there's two of them
[05:10:22] <PetefromTn_> mine had two as well one was inside the cabinet the big one with the different power taps is still underneath that big box on the back.
[05:10:41] <PetefromTn_> I should take it out and sell the damn thing maybe I can get a few bucks for the pendant I want hehe
[05:10:50] <ssi> heheh yeah
[05:10:55] <ssi> hell it's worth something just in copper
[05:10:59] <PetefromTn_> probably enough copper in ther.
[05:11:04] <PetefromTn_> LOL
[05:11:20] <PetefromTn_> its a pretty big one for what it is really.
[05:11:28] <ssi> bah the mechanical drawings in the gemini manual don't show the precise positions of the centronics connectors :(
[05:11:42] <ssi> have to get them pretty well dead nuts in the layout or it won't fit
[05:12:01] <ssi> maybe I should make a board for just the 26 pin feedback connector with the cpld on it
[05:12:14] <ssi> and then either do a separate board for the drive io connector or just handwire it

[13:59:50] <ssi> nah mine's an old singer 591 industrial machine
[14:00:00] <ssi> it's like a sailrite 111, but without the walking foot sadly
[14:00:04] <mozmck> 591, that's not even walking foot
[14:00:08] <mozmck> yeah.
[14:00:29] <mozmck> Not worth near $1000, but don't tell jdh that!
[14:00:35] <ssi> shhh, I'm trying to get jdh to buy it so I can get a walking foot machine ;)
[14:00:36] <jdh> sewing machine geekery... next thing you know there will be sewing machien pr0n
[14:01:00] <ssi> machines are machines!
[14:01:02] <mozmck> I have a pfaff 145, but I'm sure my wife won't part with it.

[14:01:27] <mozmck> and an old singer walking foot - oscillating hook.
[14:01:36] <mozmck> Nice!
[14:01:50] <mozmck> I may be one day if I can get time to get working on it.
[14:02:07] <ssi> well that was an intermediate project while I waited for the vmc
[14:02:19] <ssi> now I have the vmc, the upholstery will probably go untouched :)
[14:02:28] <mozmck> My wife has done some car upholstery on our cars.
[14:02:49] <ssi> https://scontent-a-mia.xx.fbcdn.net/hphotos-xfp1/v/t1.0-9/10672253_10100490548539302_6407225546292985700_n.jpg?oh=133d4623b69296b2b3cb4d91698ce09f&oe=54BE9D52
[14:03:02] <mozmck> neat.
[14:03:13] <mozmck> I would like one, but don't want something too large.
[14:03:22] <ssi> yeah it's not small
[14:03:23] <ssi> heh
[14:03:29] <mozmck> don't let the FAA know you have that in there!
[14:03:30] <ssi> and vmcs don't come much smaller than that
[14:03:37] <ssi> faa doesn't care
[14:03:40] <ssi> there's an airplane in there too
[14:03:55] <syyl> hey
[14:03:58] -!- sumpfralle [sumpfralle!~lars@on1.informatik.uni-rostock.de] has joined #linuxcnc
[14:04:01] <syyl> there are tabletop vmcs :)
[14:04:16] <syyl> defiance made one
[14:04:29] <mozmck> ok :) they are trying to make new rules about what you can do/have in your hangar I hear - don't know too many details.
[14:04:43] <ssi> yeah they are trying to
[14:05:06] <ssi> also, my hangars aren't on county land, they're privately owned
[14:05:14] <ssi> so the rules wouldn't apply to me even if they'd passed them
[14:05:43] <mozmck> good. I did see it had to do with getting federal money to help build the hangars or something.
[14:05:51] <ssi> what sucks about the rule they're trying to pass, is it's worded such that homebuilt airplanes don't count as airplanes til they're certificated
[14:06:03] <ssi> but folks're fighting that part
[14:06:11] <ssi> I don't mind the rule, there's lots of people using hangars as storage units
[14:06:12] <mozmck> Fed takes our money, gives a little back with strings attached.
[14:06:13] <ssi> and that needs to quit
[14:06:21] <mozmck> I see.
[14:06:32] <ssi> they're extremely cheap in terms of storage space
[14:06:54] <ssi> $100/mo for a 10x10x10 storage unit, or $300/mo for a 42x37x25 hangar
[14:06:54] <mozmck> huh, didn't know that.
[14:07:10] <mozmck> Makes sense.
[14:07:26] <ssi> problem is, folks figure that out and rent hangars for storage
[14:07:32] <ssi> then there's waiting lists at airports to get into hangars
[14:07:38] <ssi> the airport I'm at is 65 miles from my house
[14:07:44] <ssi> there's an airport 1.5 miles from my house
[14:07:46] <mozmck> ouch!
[14:07:49] <ssi> but it has a fifteen year hangar waiting list
[14:07:53] <mozmck> I knew there were waiting lists.
[14:12:15] <ssi> argh
[14:12:25] <ssi> I bought a cheapy external hdd enclosure the other day

[14:13:32] <mozmck> yeah, bummer
[14:13:32] <ssi> and an extremely full SSD and room needs to be made
[14:14:24] <jdh> I stuck a new HDD in my wife's computer the other day to let her do backups. It saw it and offered to RAID1 it so I just went with that.
[14:14:37] <mozmck> I have my OS on and SSD, and put symlinks in my home directory so most of my data is on an internal SATA HDD.
[14:14:38] <jdh> wonder if you can actually recover the raid if one fails

[14:28:28] <ssi> :)
[14:28:30] <ssi> what's happening
[14:29:01] <PetefromTn_> meh not much.. I gotta finish the damn parts I am making here and then my kids want me to climb up in the attick and get down the Halloween decorations...
[14:29:29] <jdh> that's what kids are for
[14:29:31] <jdh> send them up
[14:30:06] <PetefromTn_> well honestly they would love that but my damn attick stairway is kinda modded and steep due to the 9.5' plus ceiling in the shop.
[14:30:35] <PetefromTn_> it is a bit funky and I need to get it redone somehow.
[14:32:31] <FinboySlick> PetefromTn_: You mean to tell me the parts aren't done yet?
[14:32:49] <PetefromTn_> well that depends which parts are you talking about?
[14:33:11] <FinboySlick> Doesn't matter, so long as I'm putting useless pressure on you.
[14:33:25] <PetefromTn_> Oh well thanks I need more useless pressure in my life.
[14:33:47] <FinboySlick> :)
[14:33:56] <PetefromTn_> If you mean that job I did for that large local company recently that is done and gone and paid for and money spent heh
[14:34:24] <ssi> easy come, easy go :D
[14:34:36] <PetefromTn_> Hoping to hear back from them for more work but who knows.
[14:35:19] <PetefromTn_> they seemed to be happy with it and the designer guy said he wants to send me more work as soon as they have something who knows when that will be LOL
[14:36:42] <FinboySlick> PetefromTn_: You didn't spend it all on whiskey and um... ladies of the night, right?
[14:37:09] <PetefromTn_> yeah sorry man my life is not so interesting and has not been for a LONG time now....
[14:37:46] <PetefromTn_> when you have kids and bills and everything else that comes with it I am usually just lucky to cover the spread..hoping for better here tho! ;)
[14:39:05] <FinboySlick> PetefromTn_: Take comfort good sir, in my mind, your life is pretty epic.
[14:39:27] <PetefromTn_> Well I am glad you think so highly of me... LOL
[14:40:05] <PetefromTn_> Don't let me shit you here I am a happy guy with a home and family but I just wish the business was going a bit better...typical
[14:40:40] <PetefromTn_> It would be perfect I guess If I got more work in here and finally started reading DUNE!!
[14:40:52] <FinboySlick> PetefromTn_: Oh I know. I just like to *imagine* it epic.
[14:41:04] <PetefromTn_> yeah me too

[15:18:29] <ssi> that's what's on the drive
[15:18:30] <ssi> the feedback connector
[15:18:56] <ssi> what I wanted to do was get a pcb mount mating connector for that
[15:19:00] <PetefromTn_> I found that the connector on my TECO's was a japan spec less than common one over here..
[15:19:02] <ssi> and make the board plug directly into the drive
[15:19:24] <PetefromTn_> it LOOKED a lot like some more common ones but in reality it was not.
[15:19:36] <ssi> lovely
[15:19:39] <PetefromTn_> I would make sure you know exactly what connector it is before you get too far along..
[15:19:53] <ssi> I know exactly what connector it is
[15:20:06] <ssi> I even have some on hand, but they're soldercup

[15:23:13] <ssi> it's ok
[15:23:15] <ssi> I'm just bitching
[15:23:22] <ssi> they don't seem to make what I want
[15:23:27] <PetefromTn_> well we are here to listen
[15:23:35] <ssi> I suppose my best bet is to get IDC plugs and some ribbon cable
[15:23:37] <PetefromTn_> so keep wit yer bitchin'
[15:23:44] <ssi> and terminate the other end with a regular IDC header
[15:24:01] <PetefromTn_> that is what PCW was going to do for me with my connectors.
[15:24:06] -!- vapula has quit [Quit: Leaving]
[15:24:21] <ssi> on the board I'll put a 26 pin IDC header AND I'll put footprints for phoenix terminals
[15:24:30] <ssi> and then I can use whichever comes out to be more convenient
[15:28:05] <PetefromTn_> that might actually make positioning your custom fancy FANUC fixit board in a convenient place a bit easier
[15:30:26] <ssi> yeah it will
[15:33:40] <PetefromTn_> http://knoxville.craigslist.org/mcy/4668418934.html I can't decide is this is really cool or what. I think it would be fun as hell to ride tho..
[15:34:09] <ssi> lol
[15:34:11] <ssi> too much money
[15:34:27] <PetefromTn_> Oh yeah it is too much money but the question is....is it cool?
[15:34:43] <ssi> eh
[15:34:47] <ssi> marginally :)
[15:34:59] <PetefromTn_> Honestly I think it is... but I am an old scooter guy from way back...
[15:35:39] <PetefromTn_> when I was a kid I had a Yamaha Riva 180 scoot and rode the balls off that thing for years. Lots of fun.
[15:39:31] <nofxx> please...get a real bike!
[15:39:45] <PetefromTn_> I'd ride that thing around LOL... I bet it is fun to ride.
[15:40:04] <PetefromTn_> I have HAD plenty of "REAL" bikes... about 15 actually.
[15:40:45] <nofxx> PetefromTn_, which kind of rides you like?
[15:40:55] <nofxx> trail/sport/custom
[15:41:19] <PetefromTn_> Well honestly I am a sportybike kind of guy. Personally I love a nice big ducati twin but never had one yet.
[15:41:54] <ssi> I rode a friend's 999 supersport for awhile
[15:41:55] <ssi> that was fun
[15:41:58] <ssi> and another friend's 848
[15:42:14] <nofxx> 2 man... 996/998 was always my dream
[15:42:27] <nofxx> have a 600RR, love it, but going to go trail... where I live roads sucks
[15:42:30] <PetefromTn_> That 999 is a beauty.. especially in black
[15:42:40] <nofxx> thinking about a tiger800 or maybe 1200, bmw or triumph
[15:42:50] <ssi> https://fbcdn-sphotos-c-a.akamaihd.net/hphotos-ak-xaf1/v/t1.0-9/536471_864222938852_1275719035_n.jpg?oh=275aacb89dac3bf2fb6995d4173a60a1&oe=54AA8956&__gda__=1421856369_513a0f62b702352a0895ca671625af8f
[15:43:02] <ssi> sorry it was a 900 supersport
[15:43:30] <PetefromTn_> yeah I like the 900SS actually quite a bit. They did suffer from head set cracks tho apparently.
[15:43:41] <nofxx> need to experiment that ducati twin someday... I can believe it'll be fun as 4 cyls
[15:43:56] <nofxx> can't*
[15:43:58] <ssi> nofxx: I had a triumph daytona 675 triple
[15:44:01] <ssi> and it was best of both worlds
[15:44:08] <ssi> torquey as piss, but rev'd to 14,500
[15:44:30] <nofxx> ssi, was going to be my next bike! love it
[15:45:18] <nofxx> but going trail hehe
[15:45:29] <nofxx> tired of braking!
[15:45:36] <ssi> I loved the 675
[15:45:42] <ssi> I had it the first year it was out
[15:45:43] <ssi> '07
[15:46:46] <nofxx> ssi, also by triumph.. the rocket! hah need to ride it someday
[15:47:36] <PetefromTn_> If I get another bike it will PROBABLY be an older bike to build into a cafe racer...
[15:47:46] <ssi> yeah
[15:47:51] <ssi> I won't get another bike
[15:47:54] <ssi> that part of my life is over :)
[15:49:16] <PetefromTn_> https://www.youtube.com/watch?v=oGadGdk75tc Not sure why but this bike gives me a stiffie LOL...
[15:50:09] <ssi> looks odd with the tank so high

[15:52:32] <ssi> bring it home to experiment with
[15:52:40] <ssi> I wish I'd done that yesterday :/
[15:53:23] <PetefromTn_> It would be a good idea to do that set it up and get it to lock down right OFF the machine is much safer anyways.
[15:53:50] <ssi> yeah
[15:53:58] <ssi> which motor would be easiest to pull?
[15:54:07] <PetefromTn_> Damn I wanted to run the machine this morning but it is looking really stormy outside.
[15:54:45] <PetefromTn_> on my machine the X was easiest just removed two covers and take it off..
[15:54:51] <PetefromTn_> dunno about your machine.
[15:54:55] <ssi> probably X
[15:54:58] <ssi> Y is buried inside the machine
[15:55:04] <ssi> Z is very high
[15:55:04] <ssi> heheh
[15:55:28] <ssi> maybe I'll run down there and try to pull one real quick
[15:55:31] <PetefromTn_> didn't you say you had a small forklift?
[15:55:37] <ssi> at home, yes
[15:55:42] <PetefromTn_> oh
[15:55:48] <ssi> why?
[15:56:13] <PetefromTn_> well that is how I first supported the millhead when I removed the motor at the guys shop to get the machine over here.

[15:57:52] <PetefromTn_> yeah like I said I was able to CRANK the head up by removing the bolts to the Z motor and turned the entire Z motor on it's flat mount to lift the millhead up. It actually worked pretty well.
[15:59:12] -!- quiqua has quit [Quit: quiqua]
[15:59:15] <PetefromTn_> that way you can get the head up off the table and then set it where you need it. To be able to access the table motors. If it is like mine you need the table all the way to the right.
[16:01:33] <ssi> oh shit
[16:01:36] <ssi> that's gonna be a hassle :P

[16:02:08] <PetefromTn_> Actually once the millhead is off it you can just push it...
[16:02:12] <PetefromTn_> physically I mean.
[16:02:12] <ssi> gotcha
[16:02:27] -!- FreezingCold has quit [Ping timeout: 272 seconds]
[16:02:51] <ssi> might be easier to try to pull the Y motor
[16:02:57] <ssi> I can get to the Y motor to remove the bolts
[16:03:01] <ssi> but I'm not sure what the coupler is
[16:03:06] <ssi> if the coupler just slips apart, it'll be easy
[16:03:12] <ssi> but if there's a setscrew or something I dunno how to get to it
[16:03:27] <PetefromTn_> mine were crimped on as I said before.
[16:03:35] <ssi> crimped?
[16:03:48] <PetefromTn_> which may mean if yours are similar and you removed the motors you cannot put them back without replacing the coupler.
[16:04:08] <ssi> I hope that's not the case :/
[16:04:23] <PetefromTn_> yeah it had like a steel tube and the shaft had like a wide keyway in it... then they crimped the tube into the keyway sorta kinda thing.
[16:04:34] <PetefromTn_> I was unable to reuse them but I did not plan to...
[16:04:46] <ssi> odd
[16:05:03] <PetefromTn_> It did have a large collar with a large setscrew that holds the crimp in.
[16:05:17] <PetefromTn_> I have no idea what they call that kinda coupling...
[16:05:20] <PetefromTn_> never seen it before.
[16:05:25] <ssi> oh well
[16:05:32] <ssi> I'm gonna get on the road, go try to pull one
[16:05:42] <ssi> and stop by forrest's work on the way back and pick up a cpld eval board to screw with
[16:05:45] <ssi> bbiab

[20:42:06] <ssi> Hall-less Startup on Gemini
[20:42:06] <ssi> It is possible to run motors on the Gemini without hall effect sensors. Please contact the Applications Engineers for the custom operating system.
[20:42:09] -!- PCW [PCW!~chatzilla@99.88.10.65] has joined #linuxcnc
[20:42:09] <ssi> NOTE: This feature will not work with an Emergency brake. The brake will not allow the drive to "wake and wiggle," or "wake and twitch", also known as "wake and shake". The purpose of the wake and twitch is to allow the drive to move the rotor (or platen for linears) in very small increments to determine the exact location in the electrical cycle. The Gemini drive then commutates the motor from the encoder feedback.
[20:42:15] <ssi> The standard operating system uses the hall effect sensors to determine the rotor (or platen) location at initialization and continues to look at the hall-effects until a transition occurs.

[21:15:52] Cylly is now known as Loetmichel
[21:17:39] <kfoltman> hi Loetmichel
[21:17:51] <kfoltman> do you remember the feed/speed/depth for aluminium for proxxon?
[21:18:04] <kfoltman> 800mm/20krpm/0.15mm and 1.6mm bit = broken bit
[21:18:37] <kfoltman> pocketed holes went fine but the bit died within 4cm of a profiled slot
[21:19:15] <Loetmichel> forgot cooling?
[21:19:32] <kfoltman> I sprinkled some 3-in-1 liberally, but that hardly counts
[21:19:48] <Loetmichel> get yourself a pump spray and some car winter windshield cleaner
[21:20:04] <Loetmichel> works very good to cool smeary aluminium
[21:20:04] -!- jasen has quit [Quit: Page closed]
[21:20:39] <Loetmichel> an 1,6mm 2 flute bit ground for amuminium?
[21:20:49] <kfoltman> just a random PCB endmill
[21:20:52] <archivist> lube matters, metal sticks to the tool it stops cutting
[21:20:56] <Loetmichel> that should stand F1200 and hgiher at 20krpm
[21:21:05] <Loetmichel> and ub to 0,2mm deep
[21:21:15] <kfoltman> is it normal that the aluminium basically becomes a dust instead of a chip?
[21:21:26] <Loetmichel> for a proxxon: yes
[21:21:53] <kfoltman> I was going to reduce F to 400
[21:22:02] <kfoltman> maybe wrong type of bit
[21:22:17] <Loetmichel> archivist: actually windshield cleaner winter contains glycol, which lubes quite good
[21:22:43] <Loetmichel> or some other means of defrosting, which also seems to lube well
[21:23:00] <Loetmichel> kfoltman: use the sorotec aluminium bits
[21:23:12] <Loetmichel> WAY better than anthing made for PCbs
[21:25:39] <kfoltman> yeah, I used those 1.6mm ones just because I don't have many uses for them :)
[21:27:16] <kfoltman> Loetmichel: does it make sense to try a larger bit?
[21:27:52] <kfoltman> I have some 1/8" 'disposable' endmills
[21:27:54] <Loetmichel> no, it makes sense to use the bigges bit that fits and is made for the material in question
[21:28:32] <Loetmichel> the PCb bits have the wronge angles, too less chip room and are usually already dull when you buy them
[21:29:13] <Loetmichel> all things that are not taken well by the more smeary aluminium alloys
[21:29:26] <kfoltman> so, you mean, something like this? http://www.sorotec.de/shop/product_info.php/info/p439_end-mill-double-flute-alu--1-6mm.html
[21:30:17] <Loetmichel> yes
[21:30:23] <archivist> you will snap bits till you have some form of lube
[21:30:45] <Loetmichel> archivist: depends on his alloy
[21:31:03] <Loetmichel> al99.9: yes, will snapp even with aluminium bits
[21:31:26] <Loetmichel> AlMg3: will happily cut without any cooling/mist
[21:31:34] <archivist> copper alloyed with ally is nicer to machine

[21:35:00] <ssi> Adjective:Adjective
[21:35:11] <Loetmichel> i do
[21:35:22] <ssi> I saw a VR demo of it, looked like fun
[21:35:35] <Loetmichel> it is
[21:35:45] <Loetmichel> a bit expensive for the beta, but it is fun
[21:38:45] <kfoltman> Loetmichel: how did you mount those sheets? vacuum I suppose?

[23:22:05] <mblaszkiewicz> yes
[23:22:11] <mblaszkiewicz> it worked fine
[23:22:11] <PetefromTn_> Woah you have a BROTHER TC211? Sweet

[23:23:08] <mblaszkiewicz> it may go up for sale in a few moths cheap if I get it running and get a job or 2 through a buddy of mine
[23:23:25] <mblaszkiewicz> I'll need to upgrade

[23:25:20] <tjtr33> in axis, choose machine configuration, see if the devices & pins exist (maybe bad connections, wrong firmware, missing neccesary power)
[23:25:50] <mblaszkiewicz> I can't get it started now
[23:26:02] <jdh> are you sure you have power to the 7i77
[23:26:51] <mblaszkiewicz> yes all lights are on
[23:27:46] <jdh> cable to 7i77 is good?
[23:28:16] <mblaszkiewicz> this is weird I tried again and it just started
[23:28:30] <mblaszkiewicz> didn't even get off my chair
[23:28:53] <mblaszkiewicz> I think this machine is possesed
[23:29:10] <tjtr33> check all connections or call a priest
[23:29:31] <mblaszkiewicz> If things go right I might sell it for about 4 grand with the pc and any tooling I have for it at the time

[23:49:52] <PetefromTn_> When I was looking for my first VMC the older brother machines were some of the most attractive I was looking at. I nearly bought one from a guy in Texas.
[23:50:53] <PetefromTn_> If I did not need a CNC lathe and had already bought the VMC I have here I might have been interested. Do you have a build thread somewhere?

[23:52:50] <jdh> what makes it a drill/tap machine vs. a general purpose mill?
[23:53:15] <PetefromTn_> most are 30 taper and have sick fast rapids.. but most also have smallish travels
[23:54:09] <jdh> 300x220x200mm ?
[23:54:44] <PetefromTn_> something like that.
[23:54:52] <PetefromTn_> the older ones were smaller still.
