I'm trying to run in line a xeikon 50d and a lasermax 50 unwinder. I'm having a lot of trouble getting the web to remain centered, and the torque of the xeikon motors to remain at a constant. Is the xeikon 50d not updated enough to use the unwinder with? I'm pretty sure it was being used on a xeikon 5000, but having a lot of trouble on the 50d. Any help would be greatly appreciated.
