05:17 AM XXCoder: yo
06:40 AM XXCoder: andypugh: whats funny is that captions usage is 80% by not deaf. only 20% use captions and are hard of hearing or deaf
06:42 AM XXCoder: execllent video however
07:45 AM cloudevil_: https://smile.amazon.co.uk/gp/product/B08D9L7GY8 Well, the one I ordered arrived, and I ordered another. Cosmetically it was fine, I did not do close inspections.
07:46 AM cloudevil_: (the 5c collet chuck for 14 quid)
10:30 AM CaptHindsight[m]: http://linuxgizmos.com/3d-printer-board-runs-linux-on-allwinner-a64/
10:37 AM CaptHindsight[m]: I case you haven't been following the forums on running the stepgens on the ARISC core, this board can run Linux on the big ARM cores and stepgens on the tiny one
10:39 AM CaptHindsight[m]: I/In
10:53 AM cloudevil_: neat
10:58 AM JT-Shop: drilling depth per rev for imperial the rule of thumb is 0.001" per 1/16" of diameter +-0.001" on the total, is there a rule of thumb for metric drills?
11:00 AM Tom_L: per rev or per tooth?
11:00 AM JT-Shop: per rev
11:00 AM Tom_L: it would likely be the same just converted to some foreign measure :)
11:03 AM * JT-Shop just found a folder marked Bob Cad and that brings back some horrible memories
11:04 AM Tom_L: roflmao
11:04 AM Tom_L: oh the memories
11:06 AM Tom_L: https://www.itc-ltd.co.uk/wp-content/uploads/2015/11/drilling_speeds_and_feeds.pdf
11:06 AM Tom_L: doesn't give a rule of thumb but has ranges for different drills
11:06 AM Tom_L: you can use your own thumb
11:09 AM JT-Shop: thanks
11:11 AM cloudevil_: 15mm/m+0.05?
11:16 AM Tom_L: JT-Shop, will your pocket routine cut more and less than 4 sides?
11:17 AM Tom_L: haven't had a chance to try it
11:18 AM JT-Cave: it's pretty simple 4 sides and corner radius
11:18 AM Tom_L: still quite useful, just wondered
11:18 AM Tom_L: it gets rather complicated after that
11:20 AM JT-Cave: you could rotate the g code for an angled pocket
11:20 AM Tom_L: yes i was thinking just that
12:18 PM * JT-Shop found a Toshiba micro plc in an enclosure from the hospital and found the software too!
12:22 PM andypugh: XXCoder: I was largely inspired to make the video silent as I had thr garage door open and there were birds singing outside, it all felt relaxed and peaceful. That and really not wanting to bother trying to speak coherently.
12:23 PM andypugh: If I do it again I will probably add the captions in the YouTube interface, then I can correct the typos.
12:37 PM * robotustra thinking about pocket routine
12:44 PM drdoc: what happened to $otherPlace?
01:19 PM drdoc: CaptHindsight[m]: I run Klipper on my 3D printer
01:20 PM drdoc: it's a decent system built on a sane concept
01:45 PM CaptHindsight[m]: I know the dev from my old LinuxBIOS days
03:56 PM XXCoder: andypugh: lol ok. :)
04:53 PM JT-Shop: wow this little toshiba plc will do pwm pulse and direction
05:02 PM JT-Shop: well if nothing else got done today I finished painting my #13 post maul
05:09 PM Tom_L: JT-Shop, any luck with the servo?
05:10 PM JT-Shop: nope, ran it on the bench with 48vdc and measured ~9v on the tacho and `-9v when swapping leads on the armature
05:10 PM JT-Shop: I could take the Y servo off perhaps and see that that tacho puts out with 48vdc
05:10 PM Tom_L: is that lower than normal?
05:10 PM JT-Shop: I have no clue
05:11 PM JT-Shop: the power supply puts out 170vdc
05:11 PM Tom_L: well you'd at least have a reference then
05:18 PM CaptHindsight[m]: 1/70,000 boat person per rev. (in made up standard boat people size 5' 10")
05:20 PM CaptHindsight[m]: 1.778 meters
05:21 PM CaptHindsight[m]: 25.4um per rev
