Silhouette Studio - Test Cut - Beginner Tutorial 

You would approach the cutting speed the same way. If you have an intricate design and a piece of scrap big enough, you could slice the piece of artwork into 4 separate pieces and do a different speed for each and see what works best. Just make sure that you put a different color on each outline so you can turn them off/on as necessary. And, yes, if I were to try cutting cardboard, I would use the same method. This method will work for any substrate that you might use. Some you might get on the first try, others might take 6 or 7 test cuts before you nail it down. Thank you for watching!
