The laser control issue is a red herring, that is just distracting people. The HAL lines you wrote in your initial post should work just fine, whether you use the Z to control the laser or completely ignore it. Get to the bottom of that problem FIRST, then start thinking about the next step. Too much speculation, not enough data!
