You have: 4.444 pulses per degree of motor shaft movement. Manual is meant to say: x pulses per degree of end effector movement. The difference between both: number that corresponds to gear reduction ratio between motor and end effector. If I understand correctly, You have some kind of reducer right after the motor, so the SCALE parameter should be 4.444 * [ratio] Viesturs ------------------------------------------------------------------------------ Write once.
