There is a good chance your main board is ok. Think about what is going on here. Driving the long screws into the motor windings will have either broken one or more windings (open circuit) and/or shorted turns by damaging insulation (reduced resistance). The SOC will throw an error for both during the initialisation routine.
If you really want to be satisfied remove the motors and inspect visually, the damage will be obvious. You can also measure the resistance between motor windings, all readings should be very close.
I see so thats why it dont "send" power to the motors because the initial self check. It knows that something is broken in the motors.
I have already tried to check it visual. And i see marks. But it is so small space to look into. I need maybe dissasmble motor completely to check for sure. Thats why i'm asking if there is another solution to know.
But I think I will solder off the motor and check the windings resistance. Or can I measure them while connected to board someway. So I don' solder off the fancy factory solders on a working motor.
