VCORE 4.1 - 4.0 - 3.0 - 3.1 - 3.2H

AWD modules for Vcore ALL Vcore  (Non hybrid)

Based on the "best seller" product of BRS-ENGINEERING, the BRS-AWD for Vcore 3/3.1, I present you the BRS-AWD V2.1, different from the 2.0 to be fully adaptable on ANY VCORE machine, from the 3.0 to the 4.0, with only one CAD and 0 compromises.

Why this mod? The VC4-3.2h get the Hybrid layout...

Well most people are focused on the single toolhead setup, Hybrid CoreXY is focused for IDEX layouts. Here the BRS-AWD V2 will unlock some cool specs:

-Way less complex than the Hybrid layout: you keep only the 2 CoreXY belts (XY), no need to add 2 others for Y. This give you less parts, less variables, leading to a better reliability, a better calibration, and way less maintenance. Beside that, the system is more balanced.

-On the performance side, no need to proove AWD layouts legendary performances, it improves single toolhead acceleration, speed, but more importantly the print quality

-Easy assembly, no modifications of the Frame needed, no need of Enclosure modifications. Require at least 30-60mm more belt lenght

-Integrated brand new coaxial belt tensionner

-The more dense mechanism made on any BRS upgrade so far for a small form factor 

The New COAXIAL TENSIONNER:

As the metal VCORE 4.0 stock tensionner will be removed, a new coaxial tensionner mechanism has been developped to fit the need, and to make the system as dense as possible:

Design keypoints:

-Use LDO-42STH48-2504AH(S37)(Speedy power HT) for this setup, you can use another motor type but it needs to match the rear motors (same brand same model) and need at least a 37mm shaft 

-Delete the need of couplers and shafts like the AWD 1.36 for the previous VCORE 3.0/3.1, (less parts, less problems)

-2x M6, 1x M5, and 2x M4(used by the stock tensionner) anchor points to ensure a perfect stability

-Optionnal: Used with 48V TMC5160Pro, unlock the full potential of a sprinter machine

-No Y loss, the Y endstop need to be relocated in the AWD lower section, with a cfg correction for Y max in the printer.cfg, the VC4.0 got some margin

The Kit:

It features all the bolts, screws, bearings, always with premium quality, and PA12CF15 annealed printed parts. But without the 2x drivers and the 2x motors.

It comes partially preassembled, you just need to place it on the machine!

And as always, an assistance at any moment ;)

Version:

16/05/2025-Small fix to change the F695 bearing flange to the top

20/09/2025-Small fix to add some assembly offsets

29/12/25-V2.1b- Minor Changes to avoid clearances issue with shoulder bolt  lenght and motors

07/01/2026 V2.2- Minor change of geometry to ease printing and avoide support and make the part    stronger. VC3.x specific parts to make it easier to implement, with a better Z-Upgrade support

Compatibility:

• COMPATIBLE WITH: VCORE 4.0, VCORE 3.0, VCORE 3.1, VCORE 3.2H, Z-Upgrade 3.0

• This AWD V2 mod is compatible ONLY with the CoreXY Layout, this mod is not compatible with Hybrid layout (yet)

• It need at least the Enclosure 2.0 layout on the VC3.0/3.1 to fit the modules, standard on the VC4.0. For those having the front 3030 extrusion, this is not compatible, I advise you to grab the L3ver M3 AWD, which will get a new version soon, the M4, Full metal!

Vcore variants specifics:

The VC4.0 will use the 2x M4 insert, you need to enlarge the top hole of the top part to 5mm (with a drill) f

The Vc3.1-3.0-3.2 use an additionnal M4x60 + a 3030 M4 Tnut on both side

Each kits are comming with both screw set, meaning you can swap you AWD 2.1 module to any Vcore variant
