There seems to be some confusion by some people on what the step multiplier is for. Some people want the system to have the highest possible resolution of the encoder ( or encoder X 4 as in the viper) , so they want to run no multiplier ( 1 ).

On a servo system the system works off feedback error. If there is no error, then the drive puts no power to the motor.
Rarely under cutting and moving a machine with any friction can the drive keep a zero error.

On the bench with no friction or load, the motor will respond to a 1X multiplier, but on the machine and cutting, its just an illusion and requires very high steprates to get any speed.

On our machines i never run it less than 4X.
