MakerGear "Twin Extruder"

thingiverse

This project showcases a magnetically-coupled dual extruder system consisting of two independent single extruders connected by a shared belt drive on one axis, which only requires specific X-axis belt movements to transfer control between the two extruders, utilizing existing standard electrical components and electronics in a dual-extruder setup. The innovative principle of magnetic coupling employed here is applicable across various printers, as demonstrated on a MakerGear M2, making it an excellent reference point for modifications across different printing systems. Converting a MakerGear M2 to the "twin extruder" configuration depends on its initial configuration, with costs estimated at around $250. Most components used are sourced from MakerGear due to the end result's similarity to two running v4 single extruders on the same rail, aside from parts requiring 3D printing that can be found on Thingiverse and the project website listed below.
