If you are having X2D filament feeding issues and filament retraction issues. It is due to over greased gears in the extruder. Took mine apart and cleaned the excess grease off the extruder drive teeth. Excess grease from factory. Once cleaned, filament feeding has been working without any Ams or machine safeties being tripped. Here’s a link to disassemble head.
I will admit there is way to many things that need removed to get to the extruder gear assembly. I have a p1S and cut my teeth on that first. But the dual nozzle heads are to be expected to have a more complex design. Just wish it was ease at to clean the extruder.
