I have V2.1 of the Laser Interface PCB. I inadvertantly placed CR2 in backwards which I think reverse biased it and put 24V at the drain of Q3 MOSFET which in turn ( I believe) caused it to short. My question is, in order to complete the test out of this board, can it be operated without damage with the Q3 removed while I wait for more to come?
