I am using my new KFlop+KStep with open loop step motor and KMotion SW 4.29 and I found some strange behavior, so I decided to simplify things to make an experiment. Straight to the point:
a) I attached a small pointer to the shaft of a lonely Stepping Motor in order to have a reference.
b) Using KMotion Step Response Screen (using Step Size = 1000) pressing "Move" button a couple of times the pointer do not return to initial position. More you press bigger is the error .
c) Changing acceleration, velocity, motor nothing change, i.e. you get the error is still there.
d) Changing Step Size to -1000 instead of 1000 the movement is reversed, but the error increments to the same side as before.
