Now, this situation is becoming ridiculous...
The new controller arrived today, I installed it in the machine... and nothing, no "m" of motor moving... but this time indicator LED (at one of processor's output) was ON..
All connections seems to be OK....
I applied external 12V to board and there is PWM on FET's gate.. so this time I have board with faulty FET.
Plan now is to transfer (probably) good FET from old board to new one and see what happens...
