Good day!
I use this driver to control suction cups, axis A and Z, using micro step 16.
After performing the Zero Axis, all suction cups are aligned. After starting the loop 100 times (G code Axis A: G0 A7 G0 A0 G0 A-7 G0 A0. G code Axis Z: G0 Z7 G0 Z0 G0 Z-7 G0 Z0), KMotion show me axis A = 0, Z = 0, but in fact both right suction cups are lower than left. If I run this cycle again, the difference between suction cups will increase.
As I understand, there is little deviation appeared in the controller-driver, and it is gathering in every cycle.
Why can this happen? How can I fix this?
