A patreon request: make a guide on how to add a second Z axis to an Ender 3. In this video we achieve that, showcasing three methods to get the gantry level. This includes a mechanical belt driven kit from TH3D, adding a 2nd stepper motor in parallel, and a 2nd firmware controlled stepper with G34 auto z levelling.

If you were looking to do this upgrade, hopefully one of these methods will be suitable for you!

Everything in this video was purchased with my own money. The links all point to TH3D for convenience only. 3D printed versions of the concept are linked below.
