The Laser4DIY laser structuring machine is controlled via USB. You need a CNC control program capable of talking to a GRBL compatible CNC controller, we use LightBurn at the moment. The basic configuration (without optical amplifier) produces laser light with an average power of 0.25 W at λ= 532 nm. This corresponds approximately to a pulse energy of 20 µJ and a peak power of approx. 9 kW. We are using 2 passes with 40 mm/min each to create reliable, electrically isolating ablations. The width of the ablation is approx. 15-20 µm, which enables very fine details.
