Graphtec FC2100-50 Position alarm error

Hi team,

I have two Graphtec Plotters that I would like to repair. The machines give the message of Position alarm error.
Manual states to power off / on but the error does not go away. I checked whether there is any debris on the cutterhead sensor.

I would really appreciate it if someone who has experience leads me to the right direction on how to solve the issue.

Best,
Kaydee

When the machines are turned off - make sure the head carriages can move freely - move them by hand and see if there are any rough spots.

Position alarms are down to the servo motors these machines use - they tell the motor to move, and have a sensor to tell the machine how much the motor has turned.

Errors can be caused by bad cables, bad motors, drivers or sensors. If you've got 2, might be worth swooping around a motor at a time to see if problems fix themselves.

Most of the time it's either the driver or the cable.
