Arduino with NXT servo position won't stabilize?
I'm using the arduino PID and encoder libraries to run an NXT servo for position. Problem is, it won't move quickly to where I want, or accurately, or without oscillating all at the same time (and never for accuracy). I need it to go to exact encoder points with minimal oscillation or delay (I plan on using it in a delta bot.) I know it's not the best motor for the job, but 1) I already have enough, it costs me nothing more, 2)they're very accurate, and I know they CAN be run just fine (the NXT itself works great).
I've looked on websites and stuff for tuning, but nothing I found works, because of the weirdness of the motor itself (which can start quickly, but takes up to 400 milliseconds to stop). The best tuning parameters I found so far are 5.5, 15, 0.75 (P,I,D).
