Single Extrusion Prints with MakerGear Dual extruder printers This video will show you how to slice for a single extruder on a MakerGear Dual extruder printer. While the video is shot for the M3-ID printer, the process is applicable to the Ultra One also. If you have not already, you will need to install the Simplify3D profiles for your printer before you print. Can't find what you're looking for?
