README

SnakeOilXY-LFR

SnakeOilXY-LFR (Large format FR4) is a complete redesign inspired by the Voron 2.x with the goal of achieving better performance, scalability, reliability, and reduced maintenance. By incorporating FR4 for structural parts alongside printed components and utilizing a metal core reinforced design, it results in a more robust motion system that is less affected by the characteristics of the filament used in the printed parts. Furthermore, it is more suitable for large format machines.

Project goals

  • 4 motors coreXY kinematic.
  • Zero-play Z joints with vibration damper built-in.
  • 9mm belt on XY axis, 12mm belt on Z axis.
  • Hybrid 3D printed + FR4 structural parts .
  • AUX fan support.
  • Active-ish chamber heater.
  • Better support and reliability for MMU/filament-loader units.
  • Thermal expansion compensation bed mount
