Filament purge cutter not moving

As the title says the filament purge cutter doesn't move during a filament change. The nozzle moves back and forth but the cutter doesn't move at all. I can move it manually no problem. I have factory reset the printer, power cycled it and used compressed air to blow any filament out. The filament change happens but it leaves a mess and doesn't adhere right to the print. I have an ad5x and am lost. Any help would be appreciated.
