[18:48:00] <cradek> requiring apic is biting our ass
[18:59:03] <jepler> sigh
[18:59:12] <jepler> it's a little late to revisit that question :(
[18:59:47] <micges> jepler: hi
[19:00:34] <jepler> hi micges
[19:00:55] <micges> I have small problem: I want to disable joint mode in my gantry machine
[19:01:11] <cradek> that sounds like a large problem
[19:01:17] <micges> can I easly do that without messing with code?
[19:01:24] <cradek> nope
[19:01:49] <cradek> also too late: I think telling people to use kins for gantries is bad for this reason - it keeps coming up
[19:02:20] <micges> last time I had problem that gui was in teleop mode but halui wasn't
[19:02:24] <cradek> the real problem with the apic thing is people aren't noticing it until after they install
[19:02:34] <cradek> ... possibly wiping out their working hardy install
[19:03:21] <jepler> I don't understand what it means to have a non-trivkins system without joint mode
[19:03:50] <jepler> if you want to command two motors with one motor-pos-cmd, then use trivkins and write it in hal
[19:04:54] <alex_joni> jepler: I think they want it only for "after" homing
[19:05:26] <micges> yes
[19:07:18] <micges> and using hal messing to do two motors on one axis on stepper machine isn't good thing
[19:09:04] <jepler> well, I don't know how much code you'll have to change, but I'm sure you'll have to change some code to achieve your goal
[19:09:41] <alex_joni> maybe add a pin to prevent modeswitch
[19:09:46] <alex_joni> and assert it when homed
[19:09:52] <alex_joni> and clear it when you unhome
[19:11:15] <micges> alex_joni: cool idea
[19:11:40] <jepler> you have your pick of where to prevent what you don't want: UI, task, or maybe motion..
[19:12:22] <micges> I think easiest will be in motion
[19:12:55] <micges> rest of code will think that everything was ok, but mode wouldn;t switch
[19:13:49] <alex_joni> motion seems like the simples hack
[19:14:21] <micges> and add this to automatic assert halui.mode.teleop after homing
[19:14:25] <micges> it should work
[19:17:34] <micges> thanks guys, speaking aloud helps
[19:22:20] <alex_joni> most of the time
