RST ROM is how to firmware reset.
You not select PORT as I show in picture. When you not select PORT and give power to laser board laser go full power.
Problem is you not select port to connect laser to computer.
Try swapping the driver between X/Y and see if the problem follows, then you know for sure the driver is bad. They are very cheap to replace or you can try to get replacement Mana SE board from the seller.
