Ehm ... I found it!
Here ...
void new_pid() {
//Compute error
pid.Compute();
rot.Compute();
// Convert PID output to motor control
MotorAspeed = compensate_slack(youtput, output, 1);
MotorBspeed = compensate_slack(youtput, output, 0);
motorspeed(MotorAspeed, MotorBspeed); //change speed
I change MotorBspeed = compensate_slack(youtput, output, 0); which has value "0" into 1 and it shows WOW - my jimmy stop going crazy anymore ![]()
