It definitely looked like a penalty, but in FRC if it looks like a penalty and smells like a penalty, well, unfortunately it might not be. - Basel A [more]

Re: AndyMark RAW Box and Potentiometer

Watch speed and backlash.... That homing routine is ok for most FRC applications, in industrial servo systems, the homing routine is...

Advance toward switch high speed.
Trip switch,
reverse direction,
run slow,
release switch.
set zero.

This method puts the gear backlash behind you...
The direction you need to move off zero, the gears have already meshed to drive that direction.

Probably over kill if you only have the one gearset, but if you have multiple gears, the backlash adds up.
