Product Description


It's finally here, the V2.0 of our acclaimed V-Core printer kit. After many builds and a lot of helpful feedback, we listened to the requests of our community and added a bunch of much wanted features, considerably upgrading our design.

Main upgrades from the previous version:
-Four-point rail system for the bed frame, as opposed to the previous cantilever design
-3x Z motors for mechanical 3 point leveling (optional feature)
-Thicker Bed Plate (4mm instead of 3mm)
-9mm belts upgraded from 6mm
-Improved belt clamps

Product Description
An ultra high quality kit that includes all frame related, aluminium plates and mechanical parts to build your CoreXY style printer. Just add electronics and a few printed parts and you're set.

With the evermore popular CoreXY printers growing within the DIY community, we noticed that it is very hard to get a good quality kit where builders can get all their mechanics in one place, with a good build guide. We also found that there are very few projects available that are fully OpenBuilds based. We want to change that.

With the V-Core, we've designed a rock solid CoreXY type printer, based on Openbuilds components, and built like a tank. By using very few printed parts, and aluminium plates for both structural integrity and motion carriage parts, we've developed an Opensource design which we believe can be a great platform to build on, and that provides a very high-quality 3D Printer with great specs.
