- G28 and G30’s behavior has been updated from the old NIST g-code standard to LinuxCNC’s. Previously when an intermediate motion was programmed, the NIST standard would move all axes to the final G28/30 stored coordinates. LinuxCNC states it only moves the axes specified in the command. For example, suppose G28’s stored position is (x,y,z) = (1,2,3) for simplicity, and we want to do an automated z-axis tool retraction and then park at the x,y location. `G28 G91 Z5` will first move the Z axis 5mm(or inches) up, then move Z to position 3 in machine coordinates. Next, the command `G28 G91 X0 Y0` would skip the intermediate move since distance is zero, but then move only the x and y axes to machine coordinates 1 and 2, respectively. The z-axis wouldn’t move in this case, since it wasn’t specified. This change is intended to make Grbl more LinuxCNC compatible while making commands, like the shown tool retraction, much easier to implement.
