Ender-3 V3 SE Troubleshooting Guide

The Ender-3 V3 SE has been very popular since its release in August 2023, not only because of its remarkable performance improvements, but also because it's easy to use and quite affordable. All3dp has praised it as the best FDM 3D printer under $200 in 2024.

In this article, we will delve into some common issues encountered while using the V3 SE 3D printer, including X-axis and Y-axis motion anomalies, unresponsive machines, motor issues, temperature deviations, and more.

We'll provide the cause analysis and solutions to these problems to help you get back to printing as quickly as possible.

Ender-3 V3 SE Troubleshooting Guide X-Axis Motion Anomaly Sound 1. Phenomenon Description

Abnormal noise during the movement of the X-axis.

2. Cause Analysis

Motor wire bad connection. Belt Over-tightened/Over-loose. 3. Troubleshooting and Solution

Check motor wires for proper connection, including the transfer board if applicable. Re-adjust the belt tension. Turn off the machine, unplug motor wires, move the axis manually, and check for abnormal noise. X-Axis Movement Stuttering 1. Phenomenon Description

The X-axis movement exhibits minor/severe stuttering.

2. Cause Analysis

Pulley assembly issues. Pulley/profile damage. Loose X-axis belt. 3. Troubleshooting and Solution

Power off, unplug motor wires, move X-axis manually, and check for jamming. Inspect pulley and profile for damage. Check if the X-axis belt is too loose. Adjust X-axis pulley eccentric nut, and check for improvement. If the issue persists, contact store.uk@creality.com. Y-Axis Motion Anomaly Sound 1. Phenomenon Description

Abnormal noise during the movement of the Y-axis.

2. Cause Analysis

Check and reconnect motor wires, inspect for abnormalities.

Motor Does Not Rotate / Homing Failure / X, Y, Z, E Axis Do Not Rotate 1. Phenomenon description

After clicking on 'Home', the faulty axis motor does not rotate. Taking the Z-axis as an example: Normally, after the XY-axis completes homing, the Z-axis should first rise by 10mm, then descend to complete Z-axis homing. If the Z-axis does not move at all after the XY-axis finishes homing, it indicates that the Z-axis motor is not rotating.

2. Cause Analysis

Motor wires are not connected properly.

3. Troubleshooting and Solution

Reconnect the motor cable of the malfunctioning axis. (The motherboard end also needs to be reconnected.) Measure Drive Voltage (Only E-axis measurable), Measure Wire Harness Continuity.Please refer to the tutorial https://www.youtube.com/watch?v=s0PsS8H5PXE Fan does not Work, Fan Abnormal Noise 1. Phenomenon description

Fan doesn't work, Fan abnormal sound, Fan noise.

2. Cause Analysis

Fan wiring loose or damaged. Something blocking the fan, Fan blade broken. Fan screw loose, wire interference. 3. Troubleshooting and Solution

Check whether something is stuck in the fan, clean the fan. Check if the cooling fan screws are loose, tighten the screws again. Check if the fan is broken, No wire interference. If it's the adapter board end of the fan, you can interchange the throat tube fan and model fan wiring at the adapter board end. Use a multimeter to measure the voltage of the fan terminal (mainboard & adapter board port) to see if it's normal (around 5V). Restart When Clicking Auto-Leveling（Heat and Restart） 1. Phenomenon description

Click to Level, The machine reboots when it returns to the lower left corner after homing/The device reboots immediately after the machine preheats.

2. Cause Analysis

The voltage setting does not meet the local standard for overseas users.

3. Troubleshooting and Solution

Before powering on, please adjust the voltage to meet the local standard. Please disassemble the base plate and check if there are any loose connections with the power supply and motherboard. Please heat the nozzle separately / heat the hotbed separately, and check if the machine will restart, if unable to heat the nozzle and heat bed simultaneously, Check if the machine will reboot.

2. Cause Analysis

The print head is wobbling. Belt Loosen. X-axis motion stuttering. Hotend kit loosening. Parameter abnomaly. 3. Troubleshooting and Solution

Adjust the eccentric nut on the X-axis. Re-adjust the tension of the belt. Check if the pulley / profile is damaged, unlock the motor and move the X-axis to check for any jamming issues. Check if the screws fixing the nozzle assembly are loose. Check if the printing parameters was modified, such as acceleration, outer wall speed, etc., you can test the Gcode files in supplementary file (In the memory card come with machine). Screen Artifacting、Graininess 1. Phenomenon description

2. Cause Analysis

Leveling Failure / Height Adjustment Failure(Applicable for versions below 1.0.6) 1. Phenomenon description

Pop-up error for leveling failure Build plate scratched by the nozzle Error occurred after only detecting a few points during the 16-point leveling process The nozzle keeps height-adjusting at the lower left corner, after repeating five times it returns to zero without proceeding with the 16-point leveling, Error Occurrence. 2. Cause Analysis

Fault phenomena 1.2 , 1. 4 can be determined as height offset issues. In this case, you can check the Z-axis compensation value. If values like -0.04, 0, -10 are observed(Exaggerated values, normal compensation values range between -1 and -3, some may slightly exceed)，it can be determined that the height calibration has failed.

3. Troubleshooting and Solution

The high adjustment module can be directly replaced. please refer to the after-sales video -- Heat Bed Adjustment Video for troubleshooting. https://www.youtube.com/watch?v=iaExzAYR_Fo Blue screen after firmware update/How to determine if the firmware update was successful/Firmware upgrade failure 1. How to determine if the firmware has been successfully updated (Reference Video:https://youtu.be/8oRuCusCyUM )

1. Screen Firmware

Inserting the TF card and powering on, firmware update interface will pop up. Once the upgrade progress (percentage) is completed, it will show Update Successful on screen.

Note: After updating, you need to shut down and remove the TF card (If the firmware update fails, refer to the after-sales tutorial https://youtu.be/8oRuCusCyUM，repeat this step.).

2. Motherboard Firmware

After inserting the SD card with the motherboard firmware, the boot blue screen display takes longer than normal startup; if the update fails, it is recommended to rename the firmware like 123.bin and update repeatedly/change cards and then update the firmware again.

Note: After the firmware is successfully updated, the firmware in the SD card needs to be deleted.

Large Temperature Fluctuation 1. Phenomenon description

When heating the hotend / hotbed temperature fluctuates significantly (Premise: temperature can reach set value)

2. Cause Analysis

The pre-set PID temperature of the machine is not suitable for the local environmental temperature. Insufficient heating power. 3. Troubleshooting and Solution

Run the automatic heat bed / nozzle PID . (Control - Temperature - Auto PID) If you have a multimeter, measure the voltage on the mainboard hotend/hotbed ports when heating. https://youtu.be/pa26JHvucrs Solution for the Non-verticality between Gantry and Base 1. Phenomenon description

The gantry is not perpendicular to the base, it tilts towards the back (on the side of the Z-axis motor).

2. Cause Analysis

The inspection measures the perpendicularity of the Z-axis material to the platform, not the perpendicularity of the Z-axis material to the surface of the base.

3. Troubleshooting and Solution

Measure the perpendicularity of the profile and the platform using a right angle ruler. Remove the Z-axis profile, check if the profile cross-section is uneven.

Hotbed/Platform Wobbling 1. Cause Analysis

Loose screws between hotbed and linear bearing block.

2. Troubleshooting and Solution

Tighten screws, contact after-sales for bearing replacement.
