Re: Prusa i3 to CNC Router - 10 years ago
To quote Dirty Harry, "A man has to understand his limitations." Understanding your equipment goes a long way here as well. I'll betcha that the I3 frame can do CNC work but one has to be cognizant of the limitations of the machine. I don't see it doing hogging out operations on 6061 aluminum billet.

I have replaced many a crimp connection and burnt wire because the cby itchytweed - Safety & Best Practices
