Cut/Etch Settings for LaserCutterSophia

Using a power of 10 appears to do nothing, 11 and up should give some useful effect. If it doesn't seem to be etching at all (it's going over the area, but isn't making any impression) then check you don't have a double-line in the path (seems to sometimes happen with Inkscape when you do stroke-to-path)

Using power of 50 or below is typically better than using 50-100
