I'm not sure I'd call that bugs. It's really working out calibration and you need to know how to do that anyway. I didn't have any bugs that I know of but I did learn how to flash my RAMPS, adjust my Z-steps, fine tune my E-steps, etc. I know there are two camps, Buy Built VS Build. Both are valid. I just think that if you are at all "handy" you'll enjoy the build process and will learn everything about your printer. Don't get me wrong, I can appreciate spending $2000 on a nice, fancy, shiny printer and getting prints off of it from day one.

Either way, the important thing is to just "get one" and get rolling. It's a fantastic experience and one that's not a fad. It's going to be around awhile. It's exciting to be part of something that's still in its infancy. I can't wait to see where we are in 5-years.
