Yea your right Pavel. I’ve been going to TinkerCad for about a month now and drawing different stuff to practice. I enjoy it! I guess the software will be the biggest challenge in all this. STL, G-Code, CAD…..I’ve watched countless videos on YouTube trying to learn all I can! I don’t know what I would do without helpful websites and videos giving help with all the ins and outs! It’s great having a world of knowledge at our fingertips now!
