10:48 AM jthornton: how do you close an issue with a push?
11:26 AM hazzy-m: jthornton: add something like Fix #520, Fixes #520, Closes #520 to the commit message
11:29 AM JT-Shop: ok thanks
06:39 PM skunkworks: will a 5mbs datarate sp490 work?
06:39 PM skunkworks: pcw_home: ^
08:10 PM Tom_L: update to 2.8 went smooth, seems to work fine so far
08:11 PM hazzy-m: great!
08:11 PM hazzy-m: are you running wheezy or stretch?
08:11 PM Tom_L: what do i need to install to play with the new pyvcp stuff?
08:11 PM Tom_L: wheezy
08:12 PM Tom_L: py..vcp whatever it is..
08:12 PM hazzy-m: you need stretch :(
08:12 PM Tom_L: dammit!
08:12 PM hazzy-m: QtPyVCP
08:12 PM Tom_L: i have stretch on the test pc here
08:12 PM Tom_L: but the pc on the mill won't run it
08:12 PM hazzy-m: eventualy it will run on wheezy, but higher priorities at the moment ..
08:13 PM Tom_L: awww... c'mon :)
08:13 PM pcw_home: skunkworks: yes
08:18 PM skunkworks: pcw_home: did you see https://www.youtube.com/watch?v=i6rJsCKzUK0
08:19 PM skunkworks: smart serial for the win!
08:19 PM pcw_home: Yeah, nice you get spindle load for free
08:22 PM skunkworks: sure - but it would be cool-er to have power or hp...
08:22 PM skunkworks: I am trying to see if there is some sort of torque pin in the stmbl drive
08:40 PM pcw_home: well current*RPM*K = HP
08:43 PM hazzy-m: pcw_home: how do you find K, empirically?
09:07 PM pcw_home: You should be able to calculate pretty close with a 80-90% efficient guess for the motor
09:07 PM pcw_home: s/efficient/efficiency/
09:09 PM pcw_home: (motor torque constant is needed also)
09:33 PM skunkworks: with the realtime spindle connection - and current - and maybe hp - I wonder how fast you could turn the feed rate down (adaptive feed) if the spindle started loading
09:42 PM hazzy-m: https://youtu.be/pKnQU4dJ1-M
09:46 PM Tom_L: nice hazzy-m
09:51 PM hazzy-m: TurBoss and Lcvette are killing it!
10:20 PM Tom_L: what repo do i need to install qtpyvcp?
10:21 PM Tom_L: nm
11:10 PM Tom_L: https://www.youtube.com/watch?v=pKnQU4dJ1-M&feature=youtu.be
11:10 PM Tom_L: woops wrong channel
11:44 PM TurBoss: Tom_L: https://github.com/kcjengr/qtpyvcp
