... the mirrors are surface-coated metal mirrors out from old copiers.
My 'toolpath' is - "Pictures by PC" as CAD/CAM, exporting the NC-code as Isel NCP and processing it with Editasc10.
For a really big working area you'll need a laser with superb koherency and/or gigantic mirrors for a diode setup, as the focus quality is linear depending on distances and diameters in the optical head -- e.g. with a beam diameter of 8mm at the focussing lens in 15mm distance to the diode I'm receiving a really 'bad' focus of 0.4x0.01mm in 150mm distance ...
