You are correct. The length and width are measured by two different sources. Width is by the Board Sensor and Length, by the Tracking Roller (brass wheel) until the compression roller drops and then the board sensor kicks on to find the ends of the board.
First question is, what is your head pressure?
Second, is your board flat, warped, bowed, have divits on bottom edge that rides on brass wheel?
Third, is the compression roller dropping down or is it pushing the board out the back of the machine?
Are you adding 7" and saying NO to stay under rollers?
Finally, did you put masking tape on edge that rides brass wheel?
