I have a designed I made see attached. The machine will first have me load a 90 carve right bit then the machine will ask me to load a 1/16 bit. The machine will not recognize the bit and keeps telling me to load a 1/16 bit. I do have the sign cutting package. I successfully carved a sign with the first file. I then added the centerline to the text carvings. it was at this point my problems began with the bit issue. I have attached the file and asking for help
