12:29 AM rue_mohr: I wonder if thats large enough port for hte mecha pneumatic lines
12:29 AM rue_mohr: dont think so
12:33 AM rue_mohr: geez, some of these feedback scores are awefull
12:43 AM * rue_mohr : tea #8
12:43 AM rue_mohr: this explains why I'm out of milk by monday
12:55 AM rue_mohr: ok, thats some more for the postbox anyhow
02:13 PM zhanx: rue_mohr: my j head hot end was in the mail when i got home.

04:47 PM Tom_L: wtf are they up to now
05:19 PM rue_mohr: !?
05:19 PM rue_mohr: apr 1?
05:20 PM Tom_L: https://www.youtube.com/watch?v=quN37YskoaM
05:20 PM rue_mohr: gotta be an ampr 1
05:21 PM Tom_L: and it does walk to the job https://www.youtube.com/watch?v=7hEXwyJ2B78
05:21 PM rue_mohr: haha
05:22 PM Tom_L: seriously who would run debian under windows anyway?
05:49 PM Tom_L: how was class?
06:08 PM rue_mohr: subdued, which was nice
06:08 PM Tom_L: did you drug him?
06:08 PM Tom_L: same kid?
06:11 PM Tom_L: why did they stop putting PSU in cheap pc cases now?
06:11 PM rue_mohr: everyone hated them?
06:11 PM Tom_L: i use em
06:12 PM Tom_L: i need a case for a board i've got here
06:18 PM Tom_L: aww crap.. i completely forgot about one i've got behind the desk
06:20 PM Tom_L: wtf board is in it now though?
06:24 PM rue_mohr: ?
06:27 PM Tom_L: asrock
06:27 PM Tom_L: huh
06:28 PM Tom_L: i can use that to test what i need
06:38 PM Tom_itx: https://www.ebay.com/p/5-Axis-CNC-Breakout-Board-With-Optical-Coupler-for-Mach3-Stepper-Motor-Driver/508333082?iid=191812777725&_trkparms=aid%3D222007%26algo%3DSIM.MBE%26ao%3D2%26asc%3D44040%26meid%3Db11df40493e54bc0bc84f4c840c21ada%26pid%3D100005%26rk%3D5%26rkt%3D6%26mehot%3Dpp%26sd%3D152656202014%26itm%3D191812777725&_trksid=p2047675.c100005.m1851
06:38 PM Tom_L: you ever try any of those?
07:01 PM rue_mohr: dont need to, have marlin
07:01 PM rue_mohr: and its parallel, why would I?
08:03 PM Tom_L: what do you use on your mills?
08:22 PM rue_bed: marlin
08:22 PM Tom_L: avr 2560?
08:41 PM rue_bed: y
08:42 PM rue_bed: ewait
08:42 PM rue_bed: no
08:42 PM rue_bed: the2560 isthe printer
08:42 PM rue_bed: the cnc is just uno
08:42 PM rue_bed: m328
08:43 PM Tom_L: i had an idea for you but you would't go for it anyway
08:46 PM rue_bed: do tell!
08:46 PM rue_bed: sounds like the parALLel port makes mach3 slow as a snail
08:47 PM rue_bed: when I upgraded armyofevilrobots machine from mach3 to GRBL it was WAY faster
08:47 PM rue_bed: sorry I use grbl, not marlin
08:47 PM rue_bed: cant wake up today
08:47 PM rue_bed: and cant sleep
08:50 PM Tom_L: it would involve linuxcnc
08:50 PM rue_bed: yep
08:50 PM Tom_L: but i haven't talked you into that and doubt i can
08:50 PM rue_bed: they make a version of bamcam for linux
08:50 PM Tom_L: i know
08:51 PM rue_bed: was going to try it before buying a windows liscence
08:51 PM Tom_L: it's not that great
08:51 PM rue_bed: no, but its better than eve3ry thng else
08:51 PM rue_bed: which is sad
08:51 PM Tom_L: there's one they've been working on but i can't remember the name
08:52 PM rue_bed: I beyt its stl of other 3d nmpodle files only'
08:52 PM Tom_L: feel like reading a bit?
08:52 PM rue_bed: no
08:52 PM rue_bed: want to either be awake or asleep, this in between thing sucks
08:53 PM Tom_L: well decide and get back when you decide awake as an option
08:55 PM Tom_L: i wonder what the chinese use for a dac on that cheap board
08:55 PM rue_mohr: resolver
08:55 PM rue_mohr: ?
08:55 PM Tom_L: for spindle control
08:56 PM Tom_L: isolated 0-10V analog voltage output can be controlled with the corresponding analog interface converter to control the spindle speed. Output port P1 port.
08:57 PM rue_mohr: millions of maxim chips
08:57 PM rue_mohr: they love examples of isolated adcs
08:58 PM Tom_L: well that board is 5 bux and that would hook you up to linuxcnc via ethernet with one of these free boards i got
08:58 PM rue_mohr: you try it first
08:58 PM rue_mohr: I think ether net is a BAD idea for real time machine control
08:58 PM Tom_L: i'm going to with another board i got along side it
08:59 PM Tom_L: no
08:59 PM Tom_L: it works good
08:59 PM Tom_L: it offloads it all to the fpga
08:59 PM Tom_L: same board as what i have on my mill now but ethernet instead of parallel port input
08:59 PM rue_mohr: 9600 baud works fine
08:59 PM rue_mohr: machine cant keep up
09:00 PM Tom_L: that's why i was asking if you were ready to make a good cnc
09:00 PM rue_mohr: so you have used it
09:00 PM rue_mohr: ?
09:00 PM rue_mohr: not hat good!
09:00 PM Tom_L: i just got it and am setting up a hdd for it right now
09:00 PM rue_mohr: but the grbl thing is working great for me
09:00 PM Tom_L: np, i'll keep it for something then
09:01 PM Tom_L: that one has 34 io and the other one is 72
09:01 PM Tom_L: 1 db25 plug and a 26pin header
09:01 PM Tom_L: for 34
09:01 PM rue_mohr: ethernet is to get around the speed problems they had with usb?
09:02 PM Tom_L: no
09:02 PM Tom_L: usb won't work for RTAI
09:02 PM rue_mohr: mhm
09:02 PM rue_mohr: and yet, the 9600 baud serial I'm using works...
09:02 PM Tom_L: not without offloading it all
09:02 PM rue_mohr: right
09:02 PM Tom_L: depends where the interpreter is
09:03 PM rue_mohr: exactly
09:03 PM Tom_L: just gives you alot better performance
09:03 PM rue_mohr: I can already outperform the motors
09:03 PM rue_mohr: ...
09:03 PM rue_mohr: I know you get different features
09:04 PM Tom_L: so if you're happy with what you have, i'll never bring it up again
09:05 PM rue_mohr: not having any issues, the only goal I have is to get my spooler to talk to my pendent, so I can get things like "run program" on it
09:05 PM rue_mohr: and do position digitization
09:05 PM Tom_L: lcnc will do all that
09:05 PM Tom_L: spooler?
09:05 PM rue_mohr: I wrote a program that spools the nc file to grbl
09:06 PM Tom_L: ahh likd DNC
09:06 PM rue_mohr: send a line, waits for OK
09:06 PM Tom_L: we did DNC on some of the big machines that had little memory
09:06 PM rue_mohr: y
09:07 PM rue_mohr: :/ I wish more of my china packages had arrived
09:07 PM Tom_L: i got my one
09:07 PM rue_mohr: I have like 30
09:08 PM Tom_L: i didn't bring up the free boards, he asked me if i wanted em
09:08 PM Tom_L: i've helped document his stuff a bit
09:08 PM rue_mohr: you gonna redo the new machine?
09:08 PM Tom_L: i'm gonna test the ethernet board one of these days
09:08 PM Tom_L: it's a drop in replacement for the one that's in there now
09:09 PM Tom_L: ether instead of parallel port
09:09 PM Tom_L: just fix up the firmware and drop it in
09:09 PM Tom_L: http://store.mesanet.com/index.php?route=product/product&product_id=302&search=7i92m
09:09 PM Tom_L: that's the 34 io one
09:10 PM Tom_L: http://store.mesanet.com/index.php?route=product/product&product_id=62&search=7i80h
09:10 PM Tom_L: that's the other one
09:10 PM rue_mohr: cheap for anyone making a big expensive machine
09:11 PM Tom_L: they're being used on industrial machines as well
09:11 PM rue_mohr: y
09:11 PM rue_mohr: crap I was suppose d to go diagnose a big kiln for a glass shop
09:11 PM Tom_L: you can program it with different bit files for different io configurations
09:12 PM Tom_L: if you need more encoders etc or whatever
09:12 PM rue_mohr: hmm I need milk
09:12 PM Tom_L: that's where xilinx comes in
09:12 PM rue_mohr: after 8 tea last night, there is almost none left
09:12 PM rue_mohr: my alteara fpga programmer arrived
09:12 PM Tom_L: what tea do you like?
09:13 PM Tom_L: i got a xilinx jtag in the drawer
09:13 PM rue_mohr: orange pokey :)
09:13 PM Tom_L: i tried some vanilla something last night
09:13 PM Tom_L: didn't care much for it
09:13 PM rue_mohr: oh, well, for special events, the mint Stash tea
09:14 PM rue_mohr: damnit, i'm gonna be groggey for the rest of the day
09:14 PM rue_mohr: might as well dress back up and go get milk
09:15 PM Tom_L: gotta finish this debian 9 iso install and add preempt-rt to it
09:15 PM Tom_L: the ethernet boards require preempt-rt instead of rtai
