Whlie I have always had a general idea about what a 3D printer produces and understood the cnc part of it. I have never looked into building my own from scratch. Till recently anyway. I'm hoping someone can give or direct me to a general parts list. Not to start a debate, but what style of frame would you suggest. I have in mind a cubed frame where most servos and hardware are placed under work area. Thank you for your help ahead of time.
