I purchased from the pattern depot a pattern titled Cover Grapes Single Switch02. A cover for an electrical outlet box with no holes. The pattern measures 4.75 wide by 5.828 high. Using those dimensions I set my board size to 12.25 by 7.0 allowing 7.0 in length to stay under rollers and inserted the cover pattern onto the board and centered both axis. When I started the machine it measured the board and said that the length was 5.281 and asked if I wanted to scale to length. Knowing that something was wrong I aborted and checked all of the length measurement problems, brass roller, o-ring etc. I put masking tape on the board edge and got the same results. I then went to the calibration mode and measured the board length and it read out 12.25 the correct measurement so all appears ok with the haardware. What am I doing wrong???
