SnakeOil XY

Fully open source configurable high speed CoreXY 3D printer. Inspired by HevORT, Voron, Annex Engineering and EVA2 design.

• Does not require any custom-machined parts or custom-cut panels.
• Can be selected one of the follwing kinematics.
  • Standard : Traditional corexy kinematic.
  • 4PR : High-performance machine with automatic squaring gantry capacity. This configuration uses custom Extended CoreXY kinematic (Mixed cartesian and corexy).
  • IDEX : Hybrid corexy IDEX.
• CoreXY, IDEX, and Extended-CoreXY kinematics.
• Designed to last, parts under stress are embedded with long bolts to handle the load.
• And our industry-leading SnakeOil technology :3

Beta 3 release (2023-01-28)

• Add IDEX variant(by Charles)
• Add 4PR variant with new Extended CoreXY kinematic
• Add klicky probe support(by Charles)
• New bed coupling kinematic using silicon spacers
• Add side-blower aux fan module
• Add EBB can toolhead board support
• Remove outdated components
• Merge toolhead design(1515 and 2020 gantry now use the same toolhead front/back/bottom design) and some small improvements on geometry
