I am using a Univelop control board with a vexta stepper motor on my Z axis.
When I drive the axis in the up direction or the down direction sometimes the motor will drive in the wrong direction. Sometimes it will only drive in one direction and tapping the up or down keyy several times it will drive up and down with the same key.
What am I doing wrong and how do I correct this problem?
