Stepmotor Module - Hard Limit

  • Hi,

    I'm working on a project with the M5Stack Core and the Stepmotor Module.
    GRBL 0.8c is pre-installed on the Module. It offers a "Hard Limit" Option ($16=1) to set a switch that turns off the motor when the "Home" Position is reached.
    Usually the Pin for the X-Motor-Hard-Limit would be "D9" on an Arduino. Does any one know how to connect an End-Switch on the Stepmotor Module since there is no D9 Pin?
