I have a problem with PWM enabled mosfet outputs (1 for HotBed, 3 for Heat-End, 3 for fans). I checked with a meter and there is no voltage on any of them. The only thing that comes to mind is too low voltage to drive the mosfet because I use a 12V power supply. I was able to get all the stepper motors, limit sensors, temperature sensors and the display running. Everything works with this power supply. I also wonder how to properly connect the External MOS module V1.0

Spider's mosfet is driven by the onboard 12V (DC-DC), but the 12V circuit on the board requires a minimum input of 15V to work properly, So , if you power up the board with 12v power supply , you can close the pin "12v" and pin "24v" with a jumper.
Thanks a lot for your help it works. The photos show my motherboard running during the first tests. Everything works very well. I have already ordered a new 24V power supply and I treat this solution as a test. I don't want to overload the mosfets with too much current. I recommend this product to everyone.
