Z-Upgrade 3.2C-H SFU1605 HEAVY DUTY Edition

Adaptation of the production grade "Z-Upgrade" for VCORE 4.0

------------------------------------------------

This is a Z-Upgrade 3.2C-H iteration (H, for heavy), It answer the need to make a very tall printer (800-1500mm)

• It features a new Starlock unit, with M5 square nuts to withstand the load
• The bottom plate of the VC4 need some modifications: 

                -5mm holes instead of the stock 3mm

                -3-4mm thickness of the plate OR place 2 3030 extrusions on the mid section

This version is the reinforced one; all arms are printed with much more perimeters, and is helped with embedded 2x 5x100mm hardened steel rod in the 3 arms parts

As heavyduty is the goal here, the decoupler system is a WS16 WobbleX from Mellow, and only concern 1605 ballscrews

-------------------------------------------------

Upgrade to replace the original Z with a ballscrew system.

More precise, very reliable over time, offers a very high repeatability in the Z movement compared to a trapezoidal screw.

Maintenance-free*. Made to last in a production line. No wobble over Z. Proofed design over 2021. More than 350+ users since 2021.

Lifetime Support

A lot of things has been reworked on this iteration compare to the previous Z-Upgrade 2.0:

• Simplification of parts list, easier implementation. direct bolt in upgrade.
• Directly bolted to the VCORE 4.0 frame and underplate. Re-use the Stock VC4 top retainers + bearings.
• No need of surelevation; the Stock VC4 feet will only need to be adjusted to the height. (+17mm)
• Compatible natively with Wobble X, Oldham V3 proofed printed rings compatible too
• Dense integration of the Wobble X in the Arms
• Motor reduction for a very high holding torque, even when the motor aren't active. Proofed for heavy future custom bed, or bigger custom print volume machines. Vcore 500 can now run standard Nema 17 without risks of fall when the motor are powered off
• Motor reduction + ballscrew allowing an insane precision over the Z-Motion, extreme constistencies, allow thin and repetable layer over time
• No maintenance needed (cleaning+thin lubrication once a year is enough)
• Z-motors easy tension over the 6mm timing belt with 1x M6 screw
• Add +10mm of Z distance (Oldham V3), or +15mm with Wobble X
• All included, no self soucing to do.
• SFU1605 reinforced version for larger/taller/heavier bed assembly machine
