K40 engraving lighter stripes
Hello, on my Brand new K40 i'm experiencing power losses during engraving. It appears as lighter stripes or areas. No matter the speed (tried from 100 to 600mm/s), laser power, material or engraving orientation nor position on the work area. Focus and alignment seems fine, cut is perfect all over the surface. Attached picture is an example.
Any hint would be appreciated.
Thanks
