Grid Artifact Lines by Dithering

Hello everyone! :slight_smile:

I have recently purchased TotemS Laser with 40W (input) and 5.5W diode.
Naturally, first thing I tried with LightBurn was the dithering of white tiles via Northon Method.

I am positively surprised by the method, but I am very disapointed by the outcome of dithering.

Somehow there are grid-lines, in a very repetitive manner. Has anyone experienced this?

Settings tested:
Speed: 1000mm/min - 2000mm/min
Power: 2W - 4W
Interval: 0.05mm - 0.15mm
Dithering: Jarvis

Thanks for support!
