08:55 AM rue_mohr: I need to put togethor a project folder for it!
10:20 AM polprog: server upgraded
06:04 PM rue_mohr: ok
06:12 PM Tom_L: !ok
06:14 PM rue_mohr: http://ruemohr.org/~ircjunk/projects/coilwinder/slide.htm
06:15 PM rue_mohr: I thoguht I took more pics
06:15 PM rue_mohr: I was sure I had one before the mods
06:16 PM rue_mohr: it used to just have a single interrupter, and used a mechanical counter
06:16 PM rue_mohr: I had put a parallel port thing on it at some point with some relay control, but I dont recall writing any software
06:17 PM Tom_L: was that plastic case part of the motor?
06:17 PM rue_mohr: 3d print
06:17 PM Tom_L: nice
06:17 PM rue_mohr: I made a backbox for it to fit that driver board
06:17 PM rue_mohr: cut out on cnc

09:42 PM rue_mohr: ok
09:43 PM rue_mohr: polprog, hows that fpga?
09:44 PM Tom_L: what's up?
09:44 PM rue_mohr: me!
09:45 PM Tom_L: pretty amazing
09:45 PM rue_mohr: got the 48" drillbit made for work
09:45 PM rue_mohr: had to tig it, out of oxygen for brazing
09:45 PM Tom_L: brazed an extension on it?
09:45 PM Tom_L: mmm
09:45 PM rue_mohr: yea
09:46 PM Tom_L: had a guy tig some cast iron for me a while back
09:46 PM Tom_L: normally i have those brazed
09:46 PM rue_mohr: did it hold?
09:46 PM Tom_L: must have...
09:46 PM rue_mohr: hard to tig, it all just bubbles away
09:46 PM Tom_L: haven't heard back from the client
09:46 PM Tom_L: the guy seemed to know his shit
09:47 PM rue_mohr: k
09:47 PM Tom_L: had all sorts of cool projects goin
09:47 PM rue_mohr: :)
09:47 PM Tom_L: told him about linuxcnc and was very interested
09:47 PM Tom_L: he had a little tabletop mill
09:47 PM rue_mohr: I'm gonna go play with a 6 phase charge pump
09:47 PM rue_mohr: oh, did anyone in #cnc have a cnc plasma cutter?
09:47 PM Tom_L: a bunch of fab shop machines
09:47 PM Tom_L: lots do
09:47 PM Tom_L: jt has one
09:47 PM rue_mohr: k
09:48 PM rue_mohr: they using linuxcnc or other?
09:48 PM Tom_L: linuxcnc
09:48 PM Tom_L: with torch height control etc
09:48 PM rue_mohr: cause I need some metal cut, and it MIGHT be easier to use linuxcnc
09:48 PM rue_mohr: easier/cheaper
09:48 PM rue_mohr: er, say that again
09:48 PM rue_mohr: cause I need some metal cut, and it MIGHT be cheaper to build a cnc plasma then get it done by the one shop that has one
09:49 PM Tom_L: could be
09:50 PM Tom_L: the mesa guy has both a low v and high v thc control
09:51 PM Tom_L: workin on a cnc program my kid hand wrote so i can cut it tomorrow maybe
09:51 PM Tom_L: he did one at the vo'tech and wants a couple more
09:52 PM Tom_L: you ever use notepad ++ ?
09:54 PM rue_mohr: I recall It was ok
09:55 PM Tom_L: i'm wondering if it does split window
09:55 PM Tom_L: to compare 2 files
09:55 PM rue_mohr: hmm, dont recall
09:55 PM rue_mohr: I remember syntax hilighting
10:05 PM Tom_L: https://www.youtube.com/watch?v=mOg5C_TusdM&feature=youtu.be
10:05 PM Tom_L: linuxcnc thc demo
10:05 PM rue_shop1: hahahah
10:05 PM rue_shop1: just flat
10:06 PM Tom_L: pretty cool though
10:06 PM rue_shop1: something super simple that is like a T-square you just clip to a table
10:06 PM rue_shop1: yea
10:10 PM Tom_L: that guy does alot of experimenting with linuxcnc to help improve it
10:11 PM Tom_L: was instrumental in getting it working decent on rpi4 too
10:20 PM rue_shop1: most of my issue with linuxcnc is interfacing with it
10:21 PM rue_shop1: grbl is easy
10:27 PM Tom_L: you can use parallel port if you want and have step & direction but it's slower
10:27 PM rue_shop1: yea
10:27 PM rue_shop1: its slow enough to make people frustrated
10:28 PM Tom_L: just depends if you need the additonal features it has
10:28 PM rue_shop1: when the guy who was using mach3 on a parallel port saw how fast I got that machine going on grbl, he was amazed
10:28 PM Tom_L: i'm not saying grbl is bad but it is lacking
10:29 PM rue_shop1: oh indeed
10:29 PM Tom_L: for quick and dirty it's hard to beat
10:29 PM rue_shop1: I dont think there is a version thats really suitable for a plasma cutter
10:29 PM rue_shop1: tho
10:29 PM rue_shop1: wtf are they using for all those laser engravers
10:29 PM Tom_L: you can use linuxcnc if you want
10:30 PM rue_shop1: the parallel port I/F is the issue
10:30 PM Tom_L: i dunno what china puts in them stock
10:30 PM Tom_L: for $59 you can have a parallel port mesa card with 72 io
10:30 PM rue_shop1: well, I have a box of parallel cables
10:31 PM Tom_L: that's what i'm using
10:31 PM Tom_L: you'd have to build in your own isolation protection though
10:32 PM rue_shop1: thought you had the fpga board
10:32 PM Tom_L: i do
10:32 PM rue_shop1: not using it for yours?
10:32 PM Tom_L: i am
10:32 PM Tom_L: i have several of them
10:32 PM Tom_L: some were given to me to test
10:32 PM rue_shop1: :) k
10:32 PM Tom_L: http://store.mesanet.com/index.php?route=product/search&search=7i90
10:32 PM Tom_L: that's the one on my mill
10:33 PM Tom_L: along with a 7i47S daughter card
10:33 PM rue_shop1: yea, its an expensive route
10:33 PM Tom_L: http://store.mesanet.com/index.php?route=product/search&search=7i47s
10:34 PM Tom_L: that's all i have
10:34 PM Tom_L: that one has spindle control
10:34 PM rue_shop1: again, I'm comparing against 1-2hrs shop time for the guys who have one
10:34 PM Tom_L: i know
10:34 PM Tom_L: but
10:34 PM Tom_L: if you built it, i'm sure you would find other uses for it
10:35 PM rue_shop1: its quality, I'm not gonna argue that
10:35 PM Tom_L: and that would offset the cost
10:35 PM rue_shop1: I cant, I dont have room for it
10:35 PM Tom_L: :)
10:35 PM rue_shop1: I dont have a plasma cutter and I dont have room
10:35 PM rue_shop1: I'd be giving it to a guy who has a cutter
10:35 PM rue_shop1: ... to get my parts made...
10:38 PM X704 is now known as tiwake
11:08 PM X704 is now known as tiwake
11:35 PM polprog: rue_mohr: oh, havent done that since then :/
11:43 PM rue_shop1: polprog, which?
