have been using an old but faithfull graphtec fc2200-90 for nearly 20 years...
untill recently when had to change a snapped drive belt then when we went to power up again....
there is no initialization routine...only the y bar moves very slowly down the table untill it get to the other end and stops
no pressing of any buttons other than the power button can stop this motion
has a sensor gone or something else.... would hate to bury this old faithfull just yet
any thoughts ??
