The Hræfn, A Contemporary Approach to Classic Linear Rod CoreXY Printers.

The Hræfn is a CoreXY 3D printer designed for efficiency, affordability, and a large build volume. This project aims to incorporate existing innovations into a simplified and easily maintainable machine, while also encouraging community involvement (Design fully open sourced). 

Printer Swept Volume: 285x295x265 (XYZ)

Bed volume: 235x235x285 (Ender-3 Bed)

Key Features

• LM8UU/LM10UU Bearing Motion System: The Hræfn utilizes an economical LM8UU/LM10UU bearing motion system instead of MGN linear rails. This choice allows for cost savings without compromising performance, making the printer accessible to users with various budgets.

• Two Styles of Bed Systems Available: The Hræfn now offers two styles of bed systems:
  • Triple Z Bed System (Still in Alpha): This system utilizes Delrin V wheels on cantilevered 2020 extrusions and printed pivoting joints for bed leveling.

• Rigid Bed System (New): The alternative bed system is a similar implementation of the Vz-bot bed system with 4 LM10UU bearings and two TR8 leadscrews linked to a single stepper motor with a closed-loop 6mm belt. It offers versatility as it rely on extrusions as the base, allowing for adaptation to various bed configurations on to the base.
• Fully Enclosed System: Minimally cut lexan/plexiglass panels are necessary to achieve a fully enclosed system for the Hræfn. This enclosure enhances temperature control and environmental stability, promoting consistent print quality.
