Ansonsten mit deiner Skizze müsstest du im Arduino Programm die GRBL umschreiben:

In der Config.h zu finden ("//" muss entfernt werden, um es zu aktivieren)
// By default, Grbl sets all input pins to normal-high operation with their internal pull-up resistors // enabled. This simplifies the wiring for users by requiring only a switch connected to ground, // although its recommended that users take the extra step of wiring in low-pass filter to reduce // electrical noise detected by the pin. If the user inverts the pin in Grbl settings, this just flips // which high or low reading indicates an active signal. In normal operation, this means the user // needs to connect a normal-open switch, but if inverted, this means the user should connect a // normal-closed switch. // The following options disable the internal pull-up resistors, sets the pins to a normal-low // operation, and switches must be now connect to Vcc instead of ground. This also flips the meaning // of the invert pin Grbl setting, where an inverted setting now means the user should connect a // normal-open switch and vice versa. // NOTE: All pins associated with the feature are disabled, i.e. XYZ limit pins, not individual axes. // WARNING: When the pull-ups are disabled, this requires additional wiring with pull-down resistors! //#define DISABLE_LIMIT_PIN_PULL_UP //#define DISABLE_PROBE_PIN_PULL_UP //#define DISABLE_CONTROL_PIN_PULL_UP
