running a job for the second year, 6mm plywood (engraving/cutting) . After +- 30 hours it starts to struggle with cutting. After changing to a new lens you are back cutting. (cleaning? spot in the middle stays) Hence, this thing was running days of 12h non stop... :) Put my last lens in today...few to go, done his job. Time for something else...at least 3x faster :D Grts,
