Orbiter Toolhead board (Orbitool) for orbiter 2 and Smart orbiter 3
should a tool-board magic smoke come out because of user error? Why? Should a tool-board be destroyed by a fault in your 3D printer? Why? My answer is NO! And this is what this tool-board is all about!
We are hobbyist, professionals and let’s face it, we do mistakes, and when the magic smoke shows up everybody is disappointed, even if we know it’s a user fault. In this board, I promise you the magic smoke is kept inside extremely tight!
This toolhead board allows you to use USB communication directly to the Raspberry PI to minimize the cables from the toolhead to the MCU.
