Hi Jim. When the blade gets hot it transfers heat to the plastic causing it to melt. If you move the blade faster the plastic doesn't melt as much and you may be able to get a better cut. But, moving the blade faster doesn't always make the best cut. Try putting clear box tape over the pattern. It allows you to see the pattern and the make up of the tape also seems to lubricate the blade allowing it to run cooler. It works great for Plexiglass but I've never used it on a cutting board. If the tape works, you should be able to use a smaller blade and slow down your cut.
Let us know if this works for you.
