Motor

Scale

• 1 step ~= 9.6 um (micro-meters).

• 104,167 steps = 1 meter.

Speed

• 1 meter, 180rpm, 1 step/stage, debug on => 2:53min.

• 1 meter, 180rpm, 1 step/stage, debug off => 2:53min.

• 1 meter, 200rpm, 1 step/stage, debug off => 2:36min.

• Speeds above 200rpm visibly cause the motor to lose steps.
