while I am 3D engraving some metal I want my z axis to move with the ammount of material i have taken of. I want to do this so the focus spot is always as small as possible. I know that you can move your z axis when you are working with a CO2 laser but why is it not possible with a fiber laser? (I know that you can do this in ezcad3.) In this way i could make parts that are more precise. can anybody help me or give me a tip?
