8. How do I remove a stuck model from the bed? Heat the hot bed to 60-70°C, then use a spatula to gently pry the model from the edge.

9. Why is the machine printing without any filament extruding? Check if the extrusion gear on the motor is loose and tighten the top screw if needed. Ensure the filament is not knotted or stuck. If the nozzle is blocked, clean the throat.

10. How do I deal with the nozzle not extruding filament? Make sure the filament is properly loaded. If the nozzle is too close to the platform, re-level it. If there’s a blockage, clean the throat. More information is available in the video tutorial:

Common Faults of the Ender 3 1. How do I handle nozzle leakage? Heat the nozzle to 230°C, remove the nozzle kit while maintaining this temperature, then detach the heating block and throat separately. Once removed, lower the temperature. Apply red glue (available from Taobao) to the threads of the throat, let it sit for 1 minute, then reassemble the throat and heating block, and reinstall the nozzle kit. If the issue persists, contact after-sales customer service. 2. What should I do if there's no reaction when heating the hot bed? If the screen doesn’t show normal room temperature when not heating, it could be a thermal problem; replace the thermistor. If the hot bed port on the motherboard doesn't output 24V when heating, replace the motherboard. 3. What should I do if the nozzle doesn’t heat up? If the screen doesn’t display the normal room temperature when not heating, replace the thermistor. If the nozzle port on the motherboard doesn’t output 24V when heating, replace the motherboard. Otherwise, replace the heating tube. 4. How do I handle a blue screen and unresponsive buttons? Ensure the screen cable is plugged into the EXP3 interface on the back of the screen. If the screen shows obvious damage, replace it. Restart the button and listen for a beep. If there’s no sound, replace the motherboard; otherwise, replace the screen. Contact after-sales customer service if the issue persists. 5. Why does the printer stop automatically during printing? If slicing is unsuccessful or not completely exported, re-slice or wait for the export buffer to complete. If file transfer interrupts during SD card printing, replace or format the SD card. Contact after-sales customer service if the issue persists. 6. What should I do if the fan doesn’t rotate or makes noise? Clean the fan and check for debris. Check and tighten screws and the fan cover if loose. If the fan blade is damaged, replace the fan. 7. How do I handle X/Y/Z limit switch failures? Check if the limit wiring has fallen off; if so, reattach it. If the limit switch is damaged, replace it. Contact after-sales customer service if the issue persists. 8. How do I deal with incomplete displays, garbled characters, or missing pixels? This is usually a screen quality problem; replace the screen.

9. What should I do if the card slot doesn’t respond to card reading? Format the SD card. Check for a loose card slot. Clean the card slot with alcohol to remove oxidation. Replace the card slot or motherboard. 10. What should I do if the power supply leaks, burns out, or has no voltage output? Replace the power supply.

11. What should I do if the extruder base or extrusion clamp cracks? Replace the extruder base or extrusion clamp.

12. What should I do if the nozzle and hot bed heat automatically when turning on the printer? This indicates a motherboard problem; replace the motherboard.
