Note:

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

• The maximum driving current of the extruder is 1A, and it is recommended to use it at about 0.8A, which will not cause excessive heat. The reason for adjusting the current: to obtain a more suitable torque to prevent the motor from overheating

Method 1: Modify the extruder pulse by firmware for 0.9° Nema 14 36mm Round Motor 400 steps per revolution:

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

Modify the extruder pulse by firmware for 1.8° Nema 14 36mm Round Motor 200 steps per revolution:

#define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 400, 435 }

Method 2: Send G code for 400 steps per revolution(can be sent by pronterface to the board to change the steps) :

M92 E870

M500

Send G code for 200 steps per revolution(can be sent by pronterface to the board to change the steps) :

M92 E435

M500

For Klipper firmware based on the 400 steps motor:

10-tooth 36 motor pulse value: 691

Klipper firmware modifies the rotation_distance value
