CNC Metal Sherpa V1.5 Mini Extruder - high temperature - Fysetc

FYSETC Metal Sherpa V1.5 CNC Extruder.

Features:

• Compact size Sherpa extruder designed for use with any printer, with dual gear filament gripping system.
• Made of aviation aluminum, which gives it resistance to high temperatures. In addition, compact and lightweight design.
• CNC POM Gear: Reduction engraving design, high transmission ratio that enables you to achieve higher extrusion torque with low noise generation.
• Features a 6.25:1 gear-driven design (for best results it is recommended to adjust it for your printer).
• Approximate weight: 137.7g.

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.
