9. Remark:

It is necessary to adjust the E axis step value of the extruder, for example: the E axis step value of Ender3 is 870.

1) The maximum driving current of the extruder is 1A, and it is recommended to use about 0.8A, which will not cause excessive heat

Reason for current adjustment: to obtain a more suitable torque to avoid overheating of the motor

2) Marlin firmware modifies the pulse method of the extruder (8 teeth, 36 motor settings)

Method 1: Adjust the extruder pulse using the firmware:

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

Method 2: Sending the G code (can be sent with the slicing software command):

M92 E870

M500

3) Motor pulse value of 10 teeth 36:691

4) Firmware Klipper modifies the rotation_distance value
