hi, recently we bought fiber laser with X, Y1, Y2 axis driven by Panasonic MINAS-A6 servos. Problem is that when we cut circle the shape is rather oval. All other shapes are perfect. CW direction cut makes deformation to the right side, CCW cut makes deformation to opposite side.
We think the problem is in synchro between X, Y1 and Y2. Therefore we downloaded parameters from all three drives to make a backup and found some differences:
