Hi RICH,
My assumption according to attached:
If my HOME pos is Z0,X0 and I am currently at X2,Z-2 and want the tool to go to Z-1 before going home, program G28 Z-1 and there should be 2 moves.
Z will go to -1 THEN both axis will (should) go to HOME. I only get the first move.
G28.1 will (should) actually run the HOMING sequence for the specified axis.
