Cutting Speeds

With my Roland, and 6mm convex and 8mm laminate, I used 250 gm of force to cut with a 45 degree blade, but should have used a 60 degree blade for less force and easier cuts.

 

I found that its not the speed but how the material lays in my plotter whiched caused the punches to rip. Try babysitting your cutter( keeping the material from bunching) keeping light tension on either end of the material and this should help. Best of luck
