I am doing good with my Ortur and Liteburn after getting a working motherboard and grounding kit. I am making Grunge or Rustic type engravings in wood. Any suggestion here are good. One question is, does making 2 passes at a lower wattage better then one pass at a higher rating?
You can create test grids of different cuts, fills and settings and try on your material to find the sweet spot for your setup. This is the best way to answer as you can play with the results you are seeing. From here, “Grunge or Rustic type engravings in wood.” could mean something entirely different from what you have in mind.
