Use a BLACK cardstock paper to place on the engraving surface.
When measuring processing distance, MAKE SURE YOU MEASURE AGAINST THE CARDSTOCK PAPER AND NOT THE ACRYLIC.
Peal the acrylic and DO NOT touch the surface.
Place on the cardstock paper and mark the processing area.
You can use the setting I mention above but a good range is between 13 - 18% and 450 - 500 mm/s
After engraving, wash with running water and a drop of dish washer liquid.
DO NOT WIPE. Place it on paper towel to dry.
You can gently wipe the rest of the water with the cloth for cleaning eyeglasses.
