Z Ballscrews and TAZ X Carriage for AO-10x and Mendelmax Printers

This project expands on my previous Linear Z Rail for AO-10x project to incorporate a pair of Z Ballscrews, 10mm X rods, and the Taz 4 X Carriage assembly, allowing the AO-10x Series printers to utilize newer toolheads, up to and including the dual extruder. Before starting this, please ensure you have all the prerequisites of the AO-10x Linear Z rail project completed. You will reuse the Z motor mounts, and portions of the top Z railmount assemblies in this project. Those files have been included for convenience, but the instructions assume you have already completed that project.

You will also need several Aelph Objects / Lulzbot files which are not mine. I have linked to those open source files for convenience but I cannot upload them here. Those files may be found at:m http://download.lulzbot.com/TAZ/4.0/production\_parts/printed\_parts/TAZ\_printers/ with specific links on the instructions page.

Ballscrews are not inexpensive, but this should be the ultimate in precision upgrades for your printer. She may not print a whole basketball, but you’ll be able to print a really detailed softball!

This is a very intensive modification. Please only attempt this if you are very experienced in 3d printer frame upgrades and modifications. Everything except the Z endstop will print without support. Add heatset inserts to the ballscrew mounts and X motor and idler pieces as needed, also the X carriage.
