Just finished building a Prusa I3 MKS2 and so time to take my old I3 (P3 Steel XL) down and do a complete upgrade. Looking to make it a dual extruder and first question is best board to try. Duet WiFi seems to be a popular choice?
Current extruder is a titan + e3d hot end, best bet is to just double it up? Move on to a different extruder set-up?
