Have you tried running a glass plate? If you still need to adjust placement it is a machine issue.( calibration ) If everything is good your conversion software needs looked at. That's all I have without knowing the CAD software and Machines

As fortune might have it, many CAD mfgrs use .pcb for their files. Just for a few: Zuken Visula, Pads Power-PCB, ACT CAM-350 and derivatives. Why not: * Read it into your present CAD system [assuming it's one that can read .pcb files] * Generate
