Description:

Wiring should only be handled when instructed to do so by an Airwolf 3D technician. Wire coloring may vary.

This is a detailed wiring diagram of the RAMBo Circuit Board, with instructions on how each component connects to the board, fuse locations, and other information relevant to its use on Airwolf 3D AXIOM Series.


The only difference in this wiring diagram is the extruder motor wire is now with the ERC wire bundle and not separate on it's own.
