Hi folks. Running into an issue with my setup flashed with GRBL 1.1f and not sure if this can be fix via configuration or if I have a faulty CNC Shield board. With nothing connected to the end stop pins, I'm getting a triggered alarm only on X. When I do a $5=1 command, I get a Y & Z alarm so it seems like only the X stop pins are inverted. Is there a way to invert only one axis? Some insight will be greatly appreciated. Cheers!
