Sherpa V1.5 Mini Extruder - Fysetc

FYSETC Sherpa V1.5 extruder.

Small size Sherpa extruder, dual gear filament gripping system designed for use with any printer.

It features a 6.25:1 gear-driven design to provide torque with near-silent operation. For best results it is recommended to adjust it for your printer.

Using an SLS printed shell, it is strong, durable and lightweight, weighing approximately 136g.

Matters need attention:

You need to change your E stepper AXIS_STEPS_PER_UNIT parameter. Like Ender3 as an example, you need to set AXIS_STEPS_PER_UNIT to 870 using our Sherpa mini rev1.5. 

Marlin - Ender3

Method 1: Change the parameter on your firmware

#define DEFAULT_AXIS_STEPS_PER_UNIT   { 80, 80, 400, 870 }

Method 2: Send Gcode to change it

M92 E870

M500

For some printers, you may need to adjust the stepper motor E current to prevent overtemp on the stepper motor. Like Ender3, the manufacturer recommend to set it to 0.35A.
