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- Remove outdated components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

Questions
How big is the Toolhead board PCB?
It measures 45 × 28.5 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Toolhead board use?
11 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
