When using SI to perform Optical Dissector workflow, or Nucleator, the servomotor of the axis 1, that is the X-axis, many times has moved by itself until the end of axis. So, I have missed the work. I think that it coluld be due a bad contact in the pins of the VGA gate. The problem initialy improved when I disconnected and reconnected the axis-1 VKA gate after turning off the control module. Now, the problem became habitual, and this maneuver does not solve the problem anymore.

There are a number of issues that could cause something like this. Please open a support case ( and we’d be happy to assist.
