Are you sure the board is clamping tightly. If it moves during a run this can happen. Before reseting the machine. Go and check your feeders. If they are off the same amount....then the machine truly has a drift in that axis...if the feeders are stil

IF YOU READ FIDUCIAL MARKS THAT ARE PARALLEL TO EACH OTHER THE PLACEMENT WILL NOT BE AS GOOD. ONE OF THE PROBLEMS WITH THIS METHOD IS IT COMPLETELY THROWS OUT THE CONCEPT OF BOARD STRETCH IN ONE AXIS. THE OTHERS MAY VARY DEPENDING ON WHAT MACHINES YO
