The laser is a 1 watt IR and focusable. It will burn wood up to 1.25" inches away, not enough power for metal. I use it to
mainly burn graphics in wood. I set the height by hand at .750", focus it and set Z axis to 0. Dark wood burns easly but light
wood like birch needs some carbon rubbed on it. I do my graphics in Inkscape with line width set to .003" and save as DXF
file type. In Cambam I have a style for the laser setting the clearence at .001", cut depth at -.001" and feed at 4"/min. With
only .002" up and down motion the laser goes on and off and stays in focus. Cambam makes the gcode file. Ben
