Fysetc Machined Mini-Sherpa Extruder

FYSETC CNC all-metal Sherpa Mini extruder for compact direct-drive builds. This is FYSETC’s machined aluminum version of the Annex Engineering Sherpa Mini concept: a lightweight dual-drive filament extruder for Voron, Ender/CR-series, Gasherbrum K3, and other FDM printers with a suitable mount.

Why choose the machined Sherpa Mini

• CNC-machined aluminum body gives the extruder a rigid, heat-resistant shell without the flex of printed housings.
• Compact, hollow-frame design keeps moving mass low for toolhead-mounted direct drive.
• CNC POM reduction gear and hard steel nano-coated drive gears provide durable filament grip for 1.75 mm filament paths.
• Moons’ 36 mm pancake motor with 8-tooth pinion is the FYSETC configuration documented for the 6.25:1 Sherpa Mini revision.

Specifications

• Manufacturer: FYSETC
• Manufacturer SKU / MPN: MMB-30022-R0487
• Body process/material: CNC aviation aluminum
• Documented weight: 137.7 g
• Motor: Moons’ 36 mm pancake stepper, 8-tooth pinion
• Extruder ratio: 6.25:1 on FYSETC’s 8T Sherpa Mini revision
• Drive current: 1.0 A max; FYSETC recommends about 0.8 A to limit heat

Fitment and setup notes

• Designed around the open-source Annex Engineering Sherpa Mini extruder family.
• FYSETC lists fitment for Voron, CR-10/CR-20, Ender-2/Ender-3 family machines, and Gasherbrum K3 when the correct mount is used.
• For Ender 3-style Marlin setups, FYSETC documents M92 E870 as a starting E-step value for the 8T configuration; calibrate extrusion after installation.
• For Klipper, set rotation distance for your exact drive gear setup and calibrate under load.

Pairs well with

• Extruder Collet ECAS04 for compact Bowden/PTFE tube retention.
• Collet Clip to lock pneumatic fittings after the tube is seated.
• Phaetus Dragonfly BMO when building a compact high-flow toolhead around a V6-style hotend pattern.

What it is not

• Not a drop-in guarantee for every printer — you still need the correct mount and firmware tuning.
• Not a printed-parts kit; FYSETC’s product documentation notes that printed parts are not included.
• Not a substitute for calibration: tune esteps/rotation distance, motor current, retraction, and pressure advance for your printer.
