Currently I am cutting 3mm MDF at 30% power, 20 mm/s, 3 passes.
I have made test at 40% power:
-10 mm/s 1 pass - brown border
-10 mm/s 2 passes - blackest border
-20 mm/s 2 passes - not as black as 10x2, but darker than 10x1
In this 3 scenarios, the cut is ok (almost identical). The burn (stain?) “outside” the hole is almost identical also. Just change the color of the burned internal border.
Should I stick to 30%, avoid as pest the 40% power? Better more speed?
Any thought will be greatly appreciated.
