To set-up stepper as servo motor, just follow the [[IONI & IONICUBE user guide]] and consider the stepper motor as servo motor. For a typical 1.8 degree/step two-phase stepping motor the correct motor type parameters are: | To set-up stepper as servo motor, just follow the [[IONI & IONICUBE user guide]] and consider the stepper motor as servo motor.

# Some motors also benefit from using third harmonic of this setting, Sin(12x) which may be enabled by setting it as TRF2 and doing same procedure for finding the optimum TRA2 value. | # Some motors also benefit from using third harmonic of this setting, Sin(12x) which may be enabled by setting it as TRF2 and doing same procedure for finding the optimum TRA2 value. | ||
'''Note:''' some motors do not receive significant benefit of these settings. In such case, it's recommended to leave these settings disabled (TRF1 & TRF2 = None and TRA1 & TRA2 = 0) to avoid making the smoothness actually worse. | '''Note:''' some motors do not receive significant benefit of these settings.
