I found out that when Graphtec comes out with a new model of plotter they stop making parts for the older plotters. Mechanically my plotter is in good shape, I just had the sensor for the pinch rollers go out and luckily it was the same sensor for the home and I was able to solder in a new sensor. I am worried that I may have another electronic problem that will not be so easy to fix. Is there anyone that has FC 7000-160 working boards, which I could purchase for backups?
