I totally disassemble the 3D printing module because the filament was not going through the heating head.
I found out that it was the motor that should guide the filament and push him down that was not working. (Green lines are not smooth, is it normal ?)
Anyone have some clues why the motor is not turning ? Should it be turning freely because mine is absolutely not turning (parts are too close to each others) ?
How to repair it ??
PS : it stops working unexpectedly. Nothing wrong before this issue.
