I have my rotary setup and runs fine if only using fill setting. However if i change to fill and line or just line and the rotors has to go back and forth while marking the line seem to shift off in the X and Y axis direction about .1 inch. I have slowed down the acc and max speed. I have also calibrated the rotary and read through the LB setting for the rotary but can seem to find the smoking gun.
Can you clarify? Is it shifting along X or shifting along Y? One axis drives the rotary while the other is moving the laser head.
