Monolith Gantry for Voron 2.4 and Trident [BETA]

Updates

14.09.2023:

I added the STLs for all of the existing combinations. Huge thanks to @krankydonkey for remixing all of the Archetype belt clamps for this flipped belt path (CAD/STLs added).

11.09.2023:

I added the complete X-axis CAD with motor mount clearances to help with toolhead compatibility checks and XY joint and/or toolhead carriage remixing.

A lot of the usable hardware combinations are also included: pins, standoffs, shoulder bolts, etc.

• Front rail: belt location from the X-beam is yet to be decided. I am open to suggestions on how we should make the flipped belt path compatible with existing Voron(mod) toolheads. XY joints CAD available for 6 and 9mm belts.

• Top rail: the included VZ-Hevort CNC toolhead compatible 6 and 9mm XY joints are easy to remix for different top rail toolheads. Please make sure the layout matches your toolhead (eg. front right belt is upper or lower). Motor mounts will be compatible with both if they're printed accordingly (normal or mirrored).

What's this?

This is a performance-oriented, configurable gantry system for Voron 2.4 and Trident. It brings VZbot AWD simplicity and Voron space efficiency together.

Available gantry configurations:

• V2 6mm AWD
• V2 9mm AWD
• VT 6mm AWD
• VT 9mm AWD

Available X-axis configurations:

• Top rail (preferred, no build volume loss with certain toolheads)
• Front rail (flipped belts, toothed side facing the X extrusion)

What's the catch?

You have to space out the front and rear panels on your printer by using 5mm or 2x3mm foam tape.

Prerequisites for Monolith AWD

• Z chain relocation on V2
• 5mm or double 3mm foam tape under the rear and the front panels, because there's a 3.6mm stepper protrusion
• OR a 4040 frame
• 9 stepper drivers (or CAN) on V2
• 8 stepper drivers on Trident
• Trident may need a bed relocation to get to the front of the bed (you can just move the PEI sheet for the same effect)
• VZ-Hevort CNC toolhead is recommended for no build volume loss (XY joints already available for 6 and 9mm belts)
• OR any toolhead that you make compatible with this gantry (top rail or flipped belt path front rail)

BOM

DISCLAIMER: A lot of this stuff is untested, so the BOM and files will change with more testing and feedback.

To keep the BOM lists relatively simple, I'm going to include all the hardware and motion parts for the motor mounts and XY joints (with the stock stuff included). X extrusion/tube mounting hardware is not included because that can vary based on the configuration.

Rails:

• Y rails: MGN9H
• X rail: MGN9H/MGN12H

X axis:

• Front rail: any stock-compatible X beam will work with the suitable mounting hardware (remixed XY joints may be required).
• Top rail: any stock-compatible X beam that can be rotated 90 degrees and can accommodate new XY joint holes will work.

Belts:

If you don't switch belt sizes, the stock length will be enough.
