Plug-in interface for External stepper Drivers

Maybe I should change the values of the resistors (12k,8.1k,3.3k,100k) to have a proper digital level. Why does it use Schottky diodes, shouldn't they be zener diodes, to protect against voltage peak?

Plug-in interface for External stepper Drivers

Hi Kent Hunter, Perhaps the expander driver - Ramps Mks Gen Tb6600 4.5A can be useful. https://articulo.mercadolibre.com.ar/MLA-841849829-driver-expansor-ramps-mks-gen-ideal-tb6600-45a-_JM Greets, Mar
