When I boot the Flsun Cube F5 with an MKS Gen L v1.0 controller board, it boots fine; it beeps, and all the LEDs come on. When I heat the hotend it works beautifully, and once up to temperature, the extruder motor feeds just like it should.
However, when I turn on the heater of the build plate, it starts heating and after about 10-12 seconds the board, specifically the MOSFET at the heat bed connection quickly begins to get hot and starts to smoke. I feel if I let it continue, either the board would catch on fire or at least burn out the board.
Does anybody have any suggestions as to how to fix this? I still haven't tried the X, Y, and Z steppers yet, but that will be coming soon.
