¶ What is a U1 error code?
To reduce maintenance difficulty and improve user experience, U1 is equipped with an error pop-up notification system.
When an abnormal condition is detected, a message window automatically appears on the screen displaying the corresponding error code.
Users can search the error code on the Snapmaker Wiki to find its possible causes and solutions to restore normal printer operation.
If the issue persists, record the error code and contact Snapmaker Technical Support for timely assistance.
Example:
Error code 0002-0523-0002-0023 indicates a toolhead picking failure.
¶ U1 error code structure
Each error code consists of four groups of four digits, representing the following meanings:
¶ 1. Severity level
| Code | Level | Device safety risk | Risk of burnout, short circuit, overheating, or fire? | Print task integrity | Will it cause print failure? | User intervention | Is user action required to recover? |
|---|---|---|---|---|---|---|---|
| 0000 | Invalid | No | No | No | No | Not required | Not required |
| 0001 | Notice | No | No | No | No | Partially required | Partially required |
| 0002 | Warning | Medium–low risk | No | Yes (print paused) | Yes (print paused) | Required | Required |
| 0003 | Error | High | Yes | Yes (print stopped) | Yes (print stopped) | Required | Required |
¶ 2. Main module code
| Code | Category |
|---|---|
| 0522 | Motion control |
| 0523 | Toolhead |
| 0525 | Filament feeder |
| 0526 | Heated bed |
| 0527 | Chamber temperature detection |
| 0528 | Homing failure |
| 0529 | G-code |
| 0530 | Detection/calibration |
| 0531 | Slicing file exception |
¶ 3. Sub-module code
Used to differentiate between submodules or subprocesses within the same main category.
¶ 4. Issue code
Represents the specific type of exception or failure.
¶ How to use U1 error codes

Important notes：
(1) Some abnormal states may have complex root causes. The displayed error code might not always represent the actual fault source.
(2) If the printer cannot be restored after following the suggested troubleshooting steps, or if the code shown does not match the real situation, please contact Snapmaker Technical Support for targeted guidance.
(3) Certain error states are still under refinement, as related evaluation methods are being optimized.
It is recommended to keep your firmware up to date to ensure accurate and complete error reporting.
