6/21/19 - M2 Dual Upgrade Kits have been discontinued.
Whether for practical or aesthetic purposes, the Dual V4 Extruder Upgrade enables your M2 3D printer to extrude two different filament materials while printing a single object. Our dual extruder upgrade kit includes complete assembly instructions and requires a 24-volt M2.
Please note that you will need to upgrade your firmware before using this product. Please visit http://firmware.makergear.com to download the correct firmware.
The Dual V4 Extruder Kit is NOT compatible with the M2 Rev G (that we are currently shipping).
