I would like to engrave some translucent white acrylic with my 4W diode laser. It shipped with a black dry erase marker. If I don’t coat the plastic with the marker, nothing happens. My question are:
- What is the function of the marker?
- Is over-the-counter dry-erase the best product for the job?
- What about paper covering?
- If you use paper, should it be adhered to the plastic, or will the adhesive interfere with the laser?
