¶ Troubleshooting Guide: Fixing Extrusion Issues
¶ Understanding the Problem:
If your Magneto X isn't extruding filament as expected, it's understandably frustrating. This issue might stem from a clogged nozzle or filament jam. Thankfully, our Lancer extruder is designed to tackle these problems efficiently.
¶ Safety First:
Be cautious during this process. The nozzle and hot end can exceed 200°C. Always avoid contact with these parts to prevent burns.
¶ Tools you need:
Here are tools you will need, including the nozzle removal tool
¶ Step-by-Step Diagnostic:
¶ 1 Preparation:
- Lower the Z-axis.
- center the toolhead.
- set the temperature to 230°C for PLA/TPU or 270°C for ABS/PETG.
¶ 2 Check Extrusion:
Select the 'Load' function to attempt extrusion. If nothing comes out, proceed to the next step.
¶ 3 Unload Filament
If the filament unloads successfully, the gears are not jammed. Move to step 4. If the filament won't unload, skip to step 12.
¶ 4 Check for Jamming
With the filament out, press the metal pin to check for extrusion at 230°C. If you see material, the jam is likely cleared.
Proceed to Setp 20: the extrusion test at the end of the guide.
If not, continue to step 5.
¶ 5 Extruder Inspection:
Remove the extruder cover
then the extruder itself,
maintaining the hotend's temperature for extrusion.
Cut the filament for easier handling.
¶ 6 Gear Check:
Examine the extruder gears for trapped filament.
¶ 7 Heatsink Check:
Look for filament protruding from the heatsink's top. If clear, move to step 8.
¶ 8 Clearing Jams:
Use a metal pin to clear any jams while the nozzle is hot. If this clears the jam, proceed to the extrusion test. Otherwise, go to step 9.
¶ 9 Nozzle Check:
Remove the nozzle and attempt to clear it with the metal pin. If successful, replace the nozzle (step 10).
Before removing the silicone cover, make sure the nozzle is not reheated and the temperature is below 40 degrees
Reheat nozzle to 230 degrees Celsius
Please wear gloves when removing the nozzle. After the nozzle is removed, a small copper pipe will fall out of the nozzle. Wearing gloves can prevent burns.
After removing the nozzle, the yellow part in the picture below will fall off, please be careful of getting burned.
After removing the nozzle, use a steel needle to extrude the material
If not, replace the hotend and meltzone set (step 11).
¶ 10 Replace Nozzle:
Install a new nozzle and conduct an extrusion test.
Proceed to Setp 20: the extrusion test at the end of the guide.
¶ 11 Hotend and Meltzone Replacement:
Replace the hotend and meltzone set, then test extrusion.

Proceed to Setp 20: the extrusion test at the end of the guide.
¶ 12 If filament does not unload and unable to pull out, we need Deep Gear inspect:
removing the extruder and inspecting the gears for trapped filament.
then the extruder itself,
maintaining the hotend's temperature for extrusion.
Cut the filament for easier handling.
¶ 13 Gear Inspection:
Ensure all filament pieces are cleared from the gears.
Here is what gear to check and the best angle to look at it.
¶ 14 Final Checks:
Examine the heatsink top for any remaining filament and remove if necessary.
Proceed to Setp 20: the extrusion test at the end of the guide.
¶ Setep 20 Extrusion Test:
Please refer this link to load filament.
Reassemble the extruder and reload the filament. If the problem persists, revisit step 3.

This streamlined guide should help you systematically address and resolve extrusion issues with your Magneto X printer, ensuring a smooth printing experience.
