Hi everybody, I have a prusa i3 hephestos and I'm trying to setup an auto leveling system by servo. I followed the Zennmasterm instructions but my servo doesn't move. I tested the voltage and It's okey but I can't move my servo with M280 M401 or M402 commands. Any ideas? I tried older and newest versions of marlin and firmware, I feel like i'm mental with this problem, everybody can move the servby PepperCiervo - Prusa i3 and variants
