¶ Troubleshooting Procedure
The machine may encounter problems during operation. Causes can include hardware connections, software errors, network issues, user settings, material properties, or environmental factors. To fix issues quickly, follow the steps below.
¶ 1. Diagnose with error codes
When an exception occurs the device will usually show a status message.
Error codes are typically structured as Status + Module Code + Specific Error Number. Status = 1 usually means an exception. You can view these codes:
- In the PC software when an error pop-up appears.
- On the device touchscreen (error pop-up or alarm area).

¶ 2. Contact Technical Support — how to prepare
Step 1 — Export your project file (.al)
- Save and package your job as a
.alproject file without changing any settings before export. Keeping the original settings helps reproduce the issue.
Step 2 — Record photos / video
If possible, record a short video that clearly shows the problem (e.g., unusual noise, abnormal motion). Include:
- The error code and message on the machine touchscreen.
- Any error pop-ups or status messages in the PC software.
- The machine area where the issue occurs (stuck parts, abnormal components, indicator lights, cable connections).
Step 3 — Email support with the following information
Please prepare and submit the following information to our technical support team at support@aliencell.com:
- Error code(s) and exact alarm message(s).
- Photos / video showing the issue and error message(s).
- Detailed steps that led to the problem (what you clicked, what job you ran, material used).
- Troubleshooting already attempted and results.
- Software name and version , machine model , and firmware version(you can get this from the touchscreen).
- Attach the exported
.alfile.
Providing accurate and detailed information is the key to fast problem resolution. Clear error codes and a comprehensive report will greatly shorten the support process. Thank you for your cooperation.
