This is intended for GRBL which doesn't use arduino's bootloader, so changing the pins would require writing the firmware through the icsp port not something everyone can do. But maybe I should switch to solder jumpers to save space / time / cost.
Should all three ms pins of the driver go through the pulldown resistor? I notice ramps only does it to ms1
