Yes but I’m not starting mine touching the work piece. I have a 6mm piece of metal on top of the work piece and then I lower the z axis until it touches the metal. That is my zero point. Because I have a dust show on mine and I can’t physically see the tip of the bit I’m using so I have to use this way. When the bit touches the metal piece it completes a circuit which turns on an led and then I know exactly where the bit is without being able to see it. But estlcam thinks I am touching the work piece when I start milling so I end up with the machine making all the cuts into air above the actual work piece.
