Feifan's open-source project, for more open-source project details, visit the Feifan community www.cn2220.com

Currently only compatible with Klipper firmware printers

Two enclosure types are available:

PTFE direct-insertion type (for personal use, apply a small amount of super glue to the PTFE tube if it's not tight enough)

PC4-M6 pneumatic fitting type (with two additional pneumatic fittings)

Note: The two enclosure types are not interchangeable

Functional Description:

Automatic print pausing upon filament depletion

Automatic print pausing upon nozzle clogging

Automatic print pausing upon filament entanglement

Automatic print pausing upon motor stall

Compatible with PLA, PETG, and ABS filaments
