Hi
I am trying to understand the cutting speeds and Laser diode power.
I have a Sculpfun 9 and have cut many pieces of 3mm MDF at a speed of 300 mm/m at an intensity of 80%.
I then tried to make a jigsaw puzzle. I stuck the picture onto the mdf using a spray adhesive. I used exactly the same settings and it did not cut through.
the only addition is a piece of paper glued onto the MDF

      At a guess the answer is the glue. Always best to do a test in situations like this. The glue used in plywood has a drastic effect on the cutting and could well be the same when applied to paper and MDF. Don’t seem possible, but some glue is very hard to cut through.
