I had been cutting out many different projects and went to start a new one and all of a sudden it wasn't cutting anymore. It was acting like it was cutting, going through all the motions and such but the blade never actually cut anything. Its as if the carriage is broken or something. I tried doing a test square, same thing goes through the motions but no cut. I tried the pressure nothing. I hadn't done anything different with the machine when it stopped. I am stuck. Please help.
