In some rare support edge cases, Orca could start extruding a new layer before moving to the correct Z height. This happened when two support layers were generated back-to-back and the next layer started exactly where the previous one ended. In that situation, there was no movement that naturally updated the Z position first. The code was clearing the “pending layer change” flag too early, so it lost track of the fact that a Z move was still required. This change ensures that if a layer change is still pending, Orca will always move to the correct Z height before the first extrusion of that layer. This guarantees that every layer starts at the correct height and fixes the missing / incorrect support layers seen in those edge cases.
