If I power the board with 24vdc will that give 24vdc to the fans or will they be 12VDC?
I notice the Electronics side of the board is 7 amps. If I have 7 motors connected at 24vdc input and each motor can draw 1.6 amps. Along with two 40Watt 24vdc cartrige heaters. And 2 fans. Will the board handle it. The 7th stepper is on your external stepper card still powered from the 12v (24v) out and the 5vdc out on the board.

Donny

If you put 24V on 12V1 everything will be 24V. Don't jumper SRC12V in that case.

The 12V1 circuit is fused with a 12A fuse. Both extruders should use 1.7A each, so it's close to max I think. But I am not sure on how much the stepper drivers actually draw while running. Maybe someone else can answer that.

Ok no jumper. I have 12vdc fans on my extruders. I notice there is a 0 to 255 setting for speed in the firmware (Marlin) for the fans. If I set the max to 127. Will that limit the max voltage to 12vdc instead of 24? Or does it not work that way? What is the M codes to turn on each fan?

Donny

M codes depend on your firmware, M106 for fan 1 on Marlin. Don't think Marlin has support for two fans, but I can be wrong here.

PWM will put 24v is short burst through the fans. I won't advise that. Best is to use a power regulator 7812.
