My cutter became inoperable, specifically, it could not move past the message to load media even after the pinch rollers were engaged. After consulting with Graphtec by email and phone, they determined that the motherboard needs replacing. Graphtec recommended that I ship the cutter to them and let them do it. I am located on Guam, so it would end up costing me well over a thousand bucks (mostly shipping costs).  I decided to order the motherboard and have a computer servicing company here install the motherboard. The technician at Graphtec was insistent that there are a couple of steps of calibration that only a certified graphtec technician would know how to do. Does anyone out there have an understanding of the "calibration" steps required upon replacement of the mother board? Any suggestions would be appreciated.
