CNC Metal Extruder Resistance Light Weight Kit Without Moon

Detailed Information About The Product:

Features: 1) CNC hollowed out full metal shell, high-quality accessories, high precision, good strength, not easy to deform, high temperature resistance
2) Hollow shell bracket design, lightweight design, light weight, less inertia
3) CNC POM gear, reduction gear design, high transmission ratio, to achieve greater extrusion torque
4) High-quality hard steel nano-coated gears, wear-resistant, good precision and long life
5) Moons 36 motor with 8 teeth, good thermal control ability, low heat generation and large torque. There is a PTFE tube metal joint at one end, which can be adapted to more models at a short distance

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.
1) 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
2) Marlin firmware modifies the extruder pulse method (8 teeth 36 motor settings)
Method 1: Modify the extruder pulse by firmware:
#define DEFAULT_AXIS_STEPS_PER_UNIT { 80, 80, 400, 870 }
Method 2: Send G code (can be sent by slicing software command):
M92 E870
M500
3) 10-tooth 36 motor pulse value: 691
4) Klipper firmware modifies the rotation_distance value
