Developed as the successor of the Frankensherpa toolhead.

Like its predecessor, DirtyBird is designed to:

• Be lightweight, allowing greater acceleration and potentially improved resonance
• Have excellent cooling performance, with dual blower fans to improve overhang performance with many materials (including PLA)
• Have fans that are mounted low on the toolhead (cf. Afterburner) to improve resonance
• Allow for easy maintenance of the extruder
• Use a simplified carriage with integrated magprobe support
• Remain compatible with stock Voron (and Ramalama) idlers
• Support Roadkill-based chainless toolhead boards

Currently, DirtyBird supports the following extruders (and more via usermods):

• LGX mini
• Sherpa mini
• Sherpa micro

And the following hotends:

• Dragon
• NF Crazy
• Rapido (HF only, UHF not supported yet)

See BOM

See Build Instructions

• MGN9 support (currently, the carriage fits MGN12 rails only)
• Filament sensor support (for Enraged Rabbit Carrot Feeder or other multi-material operation, under development)
• Integrated LED lighting (using Neopixels, currently experimental)
• Rapido hotend support (currently experimental)
• Cable chain mount (?)

• Potentially insufficient clearance between the Dragon core and the heater block of the Dragon hotend; as a result, the core may melt or otherwise cook, especially when using a silicone sock
  • Improvements have been made, but we are gathering feedback from real world usage.
• Rename files for version control/clarity (i.e. similar to Annex)
• Printed L/R marks for the fan ducts
