Robo... All i can say is that i replaced the diodes on the powersupply side of the board... they got really hot and after some searching for the data sheets i discovered that the diodes are only rated at 3 amps each. = 6amps max 2 in parallel. So i replaced them with bigger ones. I do recomend that you use a fan for the cooling of the diodes and board. I bought mine from iWannabuy and it works 100%. Using it to power my new cnc foam cutter.
