Sculpfun S9 owner and retired. Built a 60 inch Bismarck ship from plans using birch and balsa wood. Tired of using jigsaws and hand carved tools. Bought plans for the USS Constitution and started working with my new Sculpfun S9. Until I came to a snag. The measurement cut and the measurement from pdf converted to svg don’t match. Purchased a laser cut Sedgwick file on a Christmas house. That went well. Need all the help I can get. No wiz to this but patience is a virtue. Help is appreciated. James
