Ramps 1.4 fuses

Dear all,

I want power a Ranps 1.4 board with 24V. I read that I have to remove the D1 diode, check all capacitor ratings and replace the fuses.

In my case, I only want to drive the stepper motor's with the ramps board (no heating bed). I saw there was a 30V fuse connected to the 5A line and a 16V connected to the 11A line. If I were to remove the D1 diode and only use the stepper motor 5A power line, can I then just leave the fuses that are already on the board?
Or is it still recommended to replace the fuses?

Greetings, Robin

The 5A power in provides power to:
fans
hotends
vin (atmega2560 power supply)
and stepper motors

If you remove D1 then the mega is safe from getting to much voltage.
but what of the fans or the hotend?

You don't have to replace the 11A fuse if your not putting any power into that circuit.

Thank you for your response (aswell on the other topic).

I'm planning on only using the board to drive stepper motors for a robot arm I'm designing.
