Steve, EMC2 does it the same way. After a work offset and tool call, I like the next block to include G43 Hx G00 Z1. and watch the tool as it approaches the part surface (in single block). A check with a 1 inch gage block at that point gives me a little peace of mind.

(Actually, I think flicking from preview to >DRO tabs forces and update) Dunno about emc's tool offset behaviour but Mach doesn't apply the offset until the next G1 or G0 move following the M6 line. That is by design. Perhaps EMC behaves in the same way?
