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.

A lot of things has been reworked on this iteration compare to the previous Z-Upgrade:

• Simplification of parts designed, easier implementation.
• Direct bolt in upgrade.
• Number of total parts per kit reduced from 265+ to 175-. Harmonized hardware: less screws types, convenient if self-sourced. Manufacture time reduced, and price reduced.
• BK ballscrew support swapped to FK support with ANGULAR CONTACT bearing, no pre-disassembly this time
• Natively equipped with CNC Wobble X
• More dense integration of Wobble X in the arms
• Motor reduction 60:20 for a very high holding torque, even when the motor aren't active with a better tension margin. 
• Proofed for heavy custom bed, or bigger print volume machines. 
• Motor reduction + ballscrew allowing an insane precision over the Z motion, extreme constistencies, allow thin and repetable layer over time
• Still no maintenance needed (cleaning+thin lubrication once a year is enough)
• Updated Spring Guard design
• Reinforced arms possible with 5mm steel rods
• 1 version for ALL case scenario, available in 1605 and 1204 type ballscrews
• Overhaul design simplified for DIY; no supports needed, pins supports redesigned for more resilience, less material needed
• Everything included in the kit, no self soucing to do.
• Materials available: PA12-CF20 and PPS-CF20

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.

Details:

Manual (In progress)

BOM (In progress)

STEP/STL files Available on Printable

Kits printed in high quality annealed PA12-CF20 or PPS-CF20 with advanced in house process.

Compatibility:

ONLY for VCORE 4.0/4.1 CORE XY and HYBRID CORE XY

The Z-Upgrade fit exactly like the stock Z-System volume, it is then fully compatible with IDEX and VAOC. Only the 3mm holes on the bottom plates needs to be enlarged to 4mm
