    Default GRBL 1.1 ARDUINO uno pinouts

    with regards to limit switch pinouts I have seen some places noting pin 9,10 and 11 for X,Y and Z limit switches
    https://blog.protoneer.co.nz/grbl-ar...or-pin-layout/
    and some articles stating pins 9,10 and 12.

    What is right???

    Depends which version of Grbl you are using. Pin 11 is used for PWM, so the Z axis swapped from pin 11 to pin 12 when PWM support was added.

    On the arduino uno R3 and GRBL version 1.1f the pins are 9,10 and 12 as stated in the GRBL Wiki.

    If you use a different GRBL version, you have to follow the documentation for that version.

    If I remember correct, the 9,10,11 pinout was for an older GRBL version. The protoneer link is dated 2013/01/30!
