Cutting Hartco 425 with Roland GX 300

I don't have a roland but I found my settings by using the "test" funtion on my Graphtec.

I used 180 force and it cut the holes perfectly.

Hi, I have a Roland Camm-1 cutter and I am wanting to cut some Hartco material for rhinestone templates.My question is what to set the machine on. My machine just has a little slider button on the right end of the machine with numbers, 2 4 6 8 , etc. I don't know which one would be best to set it on for this material. Also, should I do 2 cuts or passes? Thanks,Vicky
