[15:22:18] <jimfleig> Gearing in one form or another will accomplish the mechanical positioning. Spending enough money to be able to read position (a rotary scale, Farrand or equivalent) is another story.
[15:25:17] <jimfleig> I haven't figured out yet how to change the A and B axes displays to show only 3 decimal places.
[15:25:42] <cradek> you'd have to edit the source
[15:25:53] <cradek> why does it matter?
[15:26:50] <cradek> if you set the scale to be 1000 instead of 40 I think the three decimal places will agree
[15:27:01] <cradek> but again your rotary velocity might suffer
[15:27:37] <cradek> or if this is still just for your demo, just switch to commanded coordinates and worry about resolution later
[15:28:05] <cradek> you won't have steppers anyway, so working on step rate issues is a waste of time
[15:28:34] <cradek> step rate and step resolution
[15:30:19] <alex_jon1> alex_jon1 is now known as alex_joni
[16:03:00] <dmessier> resolution will sacrifice speed... and speed will sacrifice resolution
[16:12:09] <fenn> or.. just get some servos that can handle the job properly
[16:14:07] <anonimasu> agreed
[16:45:12] <jimfleig> Have a good day, all. Thanks for the help today.
[16:46:05] <robin_sz> meep?
[19:01:34] <Dallur> * Dallur has quit IRC (Read error: 142 (Brain non-functional))
[21:35:17] <les_w> oops.
[21:35:20] <les_w> hi robin.
[21:39:28] <robin_sz> hi les
[21:49:56] <robin_sz> I am *very* disappointed by the way ...
[22:11:36] <les_w> I was away. why are you disappointed?
[22:12:04] <robin_sz> I spent all that time finding a nice plane for you and you havent bought it!
[22:12:36] <robin_sz> http://www.everettaero.com/
[22:12:50] <les_w> ha
[22:12:51] <robin_sz> click "aeroplanes" on left ... then "harrier" ;)
[22:12:53] <les_w> looking
[22:14:01] <les_w> nice, well I investigated the robinson R22/backyard thing
[22:14:12] <les_w> until I saw the flight envelope.
[22:14:22] <robin_sz> heh
[22:14:40] <robin_sz> ghet a harrier ... those are not old ones either, FA2, new build, 1998
[22:14:48] <robin_sz> less than 1500 hours on the clock
[22:14:58] <les_w> ha
[22:14:59] <les_w> ok
[22:15:05] <robin_sz> that was a 15/20million plane no that lon ago
[22:15:16] <les_w> let's see if I have enough change in my pocket...
[22:15:27] <robin_sz> less than 50k :)
[22:16:16] <les_w> oops phone
[22:36:46] <Jymmm> If I have a small table that slides on rod and bronz brushings, what would be a good way to "lock" it at a certain position?
[22:44:06] <robin_sz> silver solder?
[22:44:44] <Jymmm> lol, no. I mean like a thumb tab, or lock lever =)
[22:45:06] <robin_sz> oh right
[22:45:20] <robin_sz> probably some sort of thumb tab or lock lever then
[22:45:58] <robin_sz> bore a hole through an alloy block, split it with a saw, make a clamp
[22:47:14] <Jymmm> like some sorta of clam shell?
[22:47:30] <robin_sz> maybe]
