Extruder Servo Twitches

Was in the process of replacing the servo for the 3D-printing module and wanted to test out whether the servo was actually working. On the 3.2.0 firmware, I sent GCODE varying the E and (speed) F value. However the servo just moves back and forth.

Is this the intended behavior for extrusion, or should the servo be rotating in one direction??

Hello,I’m very sorry, we have stopped the maintenance and support of uarm 3.2.0 firmware, so you need to spend some time on development and research by yourself, thanks for your understanding.
