I'm looking for a way to build a height control for my fibre laser cutter (1500W) that will automatically adjust the height based on an initial setting. Something that will sense the surface metal to be cut, and adjust the cutter head to 1/16 inch for example. This is to prevent the head from crashing into the material, and improve the cut. If anyone knows of a how to video or source for a stand-a-lone unit, please advise. Thanks for your assistance! Otis
