The Mellow Sherpa MINI R2 direct drive extruder is designed for compatibility with a wide range of popular 3D printers including Voron 2.4, VzBoT, Hevort, BLV, Ender 3, and Ender 5, as well as most custom DIY 3D printer builds with standard mounting points.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What is the difference between the R2 version and the original Sherpa Mini Release 1?\u003c\/h4\u003e\n\u003cp\u003eA: The R2 version introduces specially CNC-machined ISG (Integrated Spur Gear) hardened steel gears that significantly reduce gear transmission vibration for better print quality. It also features a stronger, stiffer idler arm and increased clearance between the idler arm and core. Note that the core housing and rear housing must be reprinted when upgrading from Release 1, but the updated idler arms are backward compatible.\u003c\/p\u003e\n\n\u003ch4\u003eQ: What motor pulse and current settings should I use with the Sherpa MINI R2 and a 2209 driver?\u003c\/h4\u003e\n\u003cp\u003eA: For the 8T motor configuration, set the motor pulse to 685–695 steps\/mm. For the 10T motor, use 850–875 steps\/mm. In both cases, the recommended motor current is 0.6–1A when running with a 2209 stepper driver.\u003c\/p\u003e\n\n\u003ch4\u003eQ: Does the Sherpa MINI R2 extruder come fully assembled?\u003c\/h4\u003e\n\u003cp\u003eA: It depends on the set you choose. Set 1 includes a fully assembled Sherpa MINI R2 Extruder, while Set 2 provides the extruder parts kit for self-assembly.
