Monolith Gantry [WIP]

What's this?

This is a performance-oriented, configurable gantry platform for Voron 2.4 and Trident.

Available drive configurations:

• 2WD
• 4WD

Available belt widths:

• 6mm
• 9mm

Available X-axis configurations:

• Front rail (flipped belts, toothed side facing the X extrusion)
• Top rail (Hevort spacing, this is getting phased out and will NOT receive further updates)

Design goals

• The shortest and the simplest belt path possible without losing full bed capability even with 4WD
• 4WD without increasing belt length and idler count
• Double shear support
• Increased printed part rigidity
• Uncluttered design
• Cheap BOM

Performance expectations

2WD: Due to the 10-15cm shorter belt path, stiffer and lighter XY joints (inside Y rails) your printer should perform similarly to a 50mm smaller one equipped with the same toolhead and X axis setup.

4WD: It doesn't come at the cost of adding 20cm extra belt length and more idlers, so input shaper scaling should be close to +100% vs 2WD due to the truly halved effective belt length. IF there are no rigidity bottlekecks elsewhere, which is rarely the case.

What's the catch?

• You have to space out the front (4WD only) and rear panels on your printer by at least 5mm (Monolith Panels) or have a 4040 frame.
• The tensioner range is less than half compared to stock. Monolith is not recommended for larger than 350mm build volume.
• There's limited toolhead support currently (Archetype, Xol and the Hevort version of the VZ CNC toolhead).
• Z chain relocation/delete on V2.

DISCLAIMER: This is a challenging mod and a lot of this stuff needs further testing.

Printed parts guide

• Recommended print settings: 4 walls, 40% infill (or more), 0.2mm layer height, 0.4mm nozzle
• Recommended material for 6mm versions: ABS or better
• Recommended material for 9mm versions: ABS CF or better
• AB = normal, CD = mirrored

Front rail:

Drive	Front mounts (2x)	Rear mounts (2x)	Tensioners (2x)	XY joints (L + R)
2WD	CD	AB	AB	CD
4WD	AB	AB	AB	AB

Top rail:

• Right front belt on top: AB
• Left front belt on top: CD

Toolhead	Drive	Front mounts (2x)	Rear mounts (2x)	Tensioners (2x)	XY joints (L + R)
AB	2WD	AB	CD	CD	AB
AB	4WD	AB	AB	AB	AB
CD	2WD	CD	AB	AB	CD
CD	4WD	CD	CD	CD	CD
