Advanced Multicam Interested

I have tested clean on the multicam. I am interested in being cleared to use Sintra and other plastics/foams on the multicam CNC router. I was told at the initial class that there isn’t typically a lot of interest for Advanced multicam and the classes don’t fill up so they don’t get offered.

Is there some material I could read in lieu of taking the class? Or do I just need to research feeds and speeds and bits for the material I want to work with?

Also interested, particularly in having options for other bits (still wood).
