Before replacing the extruder/print head, please first verify the version of your printer’s extruder/print head.
You can determine your M5 printer’s nozzle version based on the extruder/print head’s method of securing the type-C cable on the nozzle. The print head without a type-C cable fixing post is the V1 version, and the print head with a type-C cable fixing post is the V2 version. Simply choose the corresponding replacement tutorial according to the correct extruder/print head version:

Abnormal phenomenon:
1. The nozzle cannot print normally.
2. Poor print quality of the print model (using Simple mode via AnkerMake Slicer).
3. Replacing other components (such as nozzle, hotend, fan, etc) cannot solve the issue of poor print quality.
Method of replacement:
1. Turn on the M5 printer’s power switch. On the screen, click Control > Move to lift the Z-axis of the nozzle assembly by 200mm and move it to the middle of the X-axis (for the convenience of the replacement process), then completely remove the filament before turning off the M5 printer’s power switch. Please make sure to wait for the hotend to completely cool down first.
2. Press and hold the pneumatic connector of the feed pipe on the nozzle assembly and carefully pull out the PTFE feed pipe.
3. Use an H2.0 hexagonal wrench to loosen the two screws on the type-C cable and carefully pull out the type-C cable.
4. Use an H2.0 hexagonal wrench to loosen the four bolts on the back of the nozzle assembly and remove the upper cover and nozzle cover of the nozzle assembly.
5. Use an H2.0 hexagonal wrench to loosen the front bottom cover bolts and remove the bottom cover.
6. Carefully pull out the left E-axis motor wire.
7. Use an H2.0 hexagonal wrench to loosen the two bolts on the left X-axis belt retaining block, then separate the X-axis belt retaining block from the nozzle assembly.
8. Use an M8 open wrench to secure the bottom anti-loosening nut and use an H3.0 hexagonal wrench to loosen the lower V-wheel of the back plate by rotating in the counterclockwise direction to separate the nozzle assembly.
9. Remove the V2 version nozzle assembly and belt buckle, then remove the nozzle back plate and nozzle assembly.
Note: There are two types of middle shells for the V2 version nozzle component, both of which can be used normally.
10. Use an H3.0 hexagonal wrench to loosen the X-axis belt tensioner.
11. Use an H2.0 hexagonal wrench to remove the old X-axis belt buckle.
12. Thread the X-axis belt through the belt buckle of the new nozzle assembly and lock the top wire of the belt retaining buckle with an H2.0 hexagonal wrench.
13. Lock the X-axis belt tensioner with an H3.0 hexagonal wrench.
14. Use an H3.0 hexagonal wrench and an M8 open wrench to loosen half of the nozzle to secure the V-wheel bolt at the bottom of the back plate.
15. Install the nozzle back plate on the X-axis beam and use an H2.0 hexagonal wrench to secure the belt buckle on the nozzle back plate.
16. Use an H3.0 hexagonal wrench and an M8 open wrench to lock the V-wheel bolt at the bottom of the nozzle back plate, then use an M10 open wrench to adjust the X-axis eccentric nut to secure the nozzle back plate on the X-axis crossbeam to make sure that it does not shake loosely.
How to Adjust the V-wheel:
Please refer to How to Adjust the Eccentric Nut of the Extruder and Printing Platform for detailed instructions.
17. Lock the nozzle assembly to the back with an H2.0 hexagonal wrench and secure the nozzle assembly to the nozzle back panel.
18. Insert the type-C cable and use an H2.0 hexagonal wrench to tighten the two bolts on the type-C cable.
19. Insert the PTFE feed pipe into the pneumatic connector to complete the replacement process.
20. The V2 extruder head features an updated system for securing the Type-C cable. A printable Type-C cable fixing clasp, ensures a more stable and reliable connection of the Type-C cable. It is highly recommended that this additional securing clasp be used
21. Insert the Type-C cable fixing clasp into the Type-C support bracket.

4. Use an H2.0 hexagonal wrench to loosen the four bolts on the back of the nozzle assembly and remove the upper cover and nozzle cover of the nozzle assembly.
5. Lock the nozzle assembly to the back with an H2.0 hexagonal wrench and secure the nozzle assembly to the nozzle back plate.
Note: There are two types of middle shells for the V2 version nozzle component, both of which can be used normally.
6. Insert the type-C cable and use an H2.0 hexagonal wrench to tighten the two screws on the print head assembly at the location of the type-C connection.
7. Insert the PTFE feed pipe into the pneumatic connector to complete the replacement process.
8. Please make sure to perform automatic leveling after replacing the nozzle assembly. Simply turn on the M5 printer’s power switch, click Control > Auto-Level to start the automatic leveling process.
9. After reaching the preset temperature, the M5 printer will automatically level itself. Please note that the entire process will take approximately 10 minutes.
10. After the automatic leveling process is completed, simply select the print model to start printing. Please make sure to carefully observe the printing of the first layer of the print model.
11. If the first layer does not adhere properly, please adjust the Z-offset accordingly by going to Control > Z-Offset > Enter a value. A negative value indicates the nozzle is moving downward. It is recommended to start with increments of -0.1, -0.2, -0.3, and so on, to observe the printing results.
