type_2 ist doch ein Quadratur-Signal. Wäre hier type_0 im 'velocity' mode nicht besser geeignet?
Code:
stepgen has two control modes, which can be selected on a channel by channel basis using ctrl_type. Possible values are "p" for position control, and "v" for velocity control. The default is position control, which drives the motor to a commanded position, subject to acceleration and velocity limits. Velocity control drives the motor at a commanded speed, again subject to accel and velocity limits. Usually, position mode is used for machine axes. Velocity mode is reserved for unusual applications where continuous movement at some speed is desired, instead of movement to a specific position. (Note that velocity mode replaces the former component freqgen.)
