Introducing Rat Rig V-Core 4.1

V-Core 4.1 is now available. The V-Core 4 experience — refined, and finally at full potential. V-Core 4.1 isn’t about chasing higher numbers or headline specs. It’s about perfecting the experience thousands of users rely on every day — from home workshops to professional production environments. This release focuses on what truly matters: consistency, reliability, and ease of ownership. From a completely redesigned full-metal toolhead and significantly improved part cooling, to a simplified plug-and-play wiring architecture, a steel X-axis gantry, and the latest RatOS 2.1 firmware — every refinement in V-Core 4.1 removes friction from daily use and helps the machine simply do what it’s supposed to do: print. No guesswork. Fewer interruptions. More predictable results. V-Core 4.1 is available now as a complete machine, and as an upgrade kit for existing V-Core 4 users. All existing panels and enclosures remain fully compatible. You’ll find all details, documentation, and product links below. ________________________________________________________________ International Store: https://ratrig.com/3d-printers/v-core-4-category.html US Store: https://us.ratrig.com/3d-printers/v-core-4-category.html ________________________________________________________________ Documentation & Resources: All documentation for V-Core 4.1 — including updated build guides, CAD files, and technical details — is available at: https://docs.ratrig.com ________________________________________________________________ Follow Rat Rig: YouTube: https://www.youtube.com/@ratrighardware Instagram: https://www.instagram.com/rat.rig Facebook: https://www.facebook.com/ratrighardware Communities: Official 3D Printer Community: https://www.facebook.com/groups/ratrig3dprintercommunity Official CNC Community: https://www.facebook.com/groups/ratrigcncmachinecommunity Discord: https://discord.com/invite/ratrig
