When you cannot find your focus height tool, there is always the option to cut a new one. We have made the drawings, all you have to do is import the drawing into your lasersoftware, place the material in the machine and cut the drawing.
We made two different drawings with different designs. Focustool steps has small, straight surfaces, on which you can rest the nozzle of the laserhead. Focustool is a smooth triangle with height-markings each millimeter.
