Z-Motion Prototyping 2 - Monolith Zero

Learning from my plastic V2 Z-joint mistake and the lead screw clearance difficulties with the toolhead, here's what's gonna change on the Z-setup:

• MGN7H/MGN12H and 1515/2020 compatibility with the same sheet metal bed mount

• Metal-on-metal clamping everywhere, M3 heat sets used as M2 spacers

• No rear extrusion, better lead screw clearance

• Beacon might be possible with the same toolhead body

• Adjustable Z-endstop at Zmax

• No preloaded lead screw nuts with triple Z

• Can be raised for higher nozzle positions

• Z-umbilical instead of the chain (better with top electronics)

• A 30mm long M3 spacer was used in the pictures instead of the required 20mm. *

My 9290 has finally cleared customs after almost 2 months, so everything is on track to make a working printer out of this thing, SoonTM.
