In particular the power supplys are borderline in these models, they fit lower wattage 300W PSU's that are absolutly maxed out with extruders and heat beds running. The Flashforge and others have 340w Psu's fitted. I belive the controller board has a 1280 cpu fitted insted of the 2560, so it is EOL as far as further firmware upgrades.
No, that is relativly simple, you use an ssr (solidstate relay) driven from the heatbed output of your main board, and hook up the heatbed and second psu on the switched side. its common practice.
