Challenging, yes. But rewarding.
I've only had my printer for a year and so far only run 4 rolls though it. My biggest problem on anything hobby related is availability, there is no one locally selling (unless it's really popular) so I need to order everything overseas with sky high shipping and customs tax...
Also, I can't print good quality until I do something with the aluminum bed, it's warped.
Thinking back, the biggest fail I did was designing too much before I got the printer. "I can design this now and then I'll just send to the printer when it arrives, it's easy"
Man, was I wrong... But did learn a lot from that mistake.
