Help for MOTOR 2.2 Kw and control board optimum BF46 milling machine

Sorry to have to say this, but your lack of understanding of electronics means you are clutching at straws. Almost certainly one or more of your output MOSFETs is faulty. Simple resistance measurements may not reveal which as it may only fail under stress. Your only option is to replace them all with known good NEW ones, you cannot assume the ones in the other board are good. Even then there may be some other failed component which will cause one or more of the new MOSFETs to fail, e.g. a dodgy high-side driver, leaving you back at square 1. You need more knowledge and more equipment than a multimeter to fault find this board.

Question: the GND wire on the hall sensor pack that you had to resolder. Was that disconnected after the fault or did it become disconnected when you disassembled the motor?
