      Dumb question: If you run a gcode file on RRF that has commands to go beyond the axis limits set in config.g, does the firmware substitute the maximum or minimum ordinate vale for that axis and apply appropriate acceleration and jerk, etc., , or does it ignore the firmware limit and allow the machine to execute the travel move beyond the axis limit? I suspect it's the former, but I can see where the latter might be a possibility, for example, if the axis limits were used only for homing the machine, as the endstops are used only for homing the machine.

        @mrehorstdmd RRF checks whether a coordinate is reachable by a given kinematics within it's axis bounds and limits moves accordingly.

        If you have different axis limits between homing and moving, you should end your homing files by moving somewhere legitimate for the movement range during non-homing-operations and redefine your axes after that.
