A Z-Upgrade complete overhaul for VCORE 4.0/4.1

The Z-Upgrade replace the original Z system with a ballscrews driven system.

More precise, more reliable over time, it offers a very high repeatability and a perfect consistancy in layer staking compared to a trapezoidal screw.

Maintenance-free and made to last in a production line. No wobble over Z.

Proofed design since 2021. More than 450+ happy users

Lifetime support and warranty over the parts

Integrated design pushed further to maximize fonctions and size to keep the whole print Z volume

Following the feedbacks, tests, assemblies, this version is born to simplify, and solve all the little things from the 3.x versions.

Parts count reduced, hardware quantity reduced, steps of assembly reduced, price reduced!

The Spring Guard from the previous revision, but better!

Springs guard will secure the balls, and will delete the possible eventuallity of them escaping the mechanism.

This can happen when lifting the bed or the PEI, or over a short over-acceleration on a Z motion by exemple.

This modification will allow a better Z accelerations (Tilt+Mesh faster)

Avoid time lost in looking for the balls which fell of.

This solution won't mess with the anti-wobble capability.

This last version allow an easier assembly, and a simplified bed arm design

New mod, new applications:

Z-Upgrade has been designed to fit all the needs: From standard stock 300mm machine to extreme 1000mm build with resilient conception in mind, the Z-Upgrade 4.0 fits for every need.
