Sherpa Mini - Release 1

We're happy to announce the first release version of Sherpa Mini.

This extruder is the result of hundreds of hours of development work and thousands of hours of testing. Sherpa Mini's signature lightweight design has been optimized even further bringing the weight down while improving stiffness. Making for the lightest FDM extruder on the market.

We are also happy to announce the launch of a Sherpa 8 tooth NEMA14 pinion motor developed in collaboration with LDO Motors. This new 8 tooth motor will improve performance in high demand applications and is a drop in replacement for the current 10 tooth motor on RC1 or later parts.

  • For now, the new motor is only available for preorder on ez3DPstore, but we are working on wider availability.
  • This motor has hundreds of test hours on it, with a measured performance increase throughout all actions of extrusion.

This is the Sherpa Mini Extruder, a ground up design developed by Anlin and the team at Annex Engineering. It's a dual geared hobbed filament extruder designed for use with any printer. It features a 5:1 gear driven design to provide torque while being able to be near silent. You must perform your own tuning to get the best results.

A Pinion Equipped Pancake Stepper is required for this Release.
