I’ve changed the speed and preasure, but It still doesn’t cut anything.

What is every thing you need to use it.. mine came with 3 mats. i know you need cartridges what else do you need? do you need like ink and stuff?

I just bought the cricut expression and I was wondering what I need to get for it it didn’t cone with any cartridges. I have no expierience with them and don’t know much about it besides what it does but I don’t know how to make it do what it does lol I will figur it out though. I know I need the different cartridges but I don’t know if it needs ink or nything else. What would you guys suggest I get for it? Is the design studio software good? I have expierience scrapbooking just not with this machine any suggestions I would appreciate. Thanks
