How to Fix the HMS_0F01-0100-0001-000E Error on Bambu Lab
If your Bambu Lab 3D printer displays the code HMS_0F01-0100-0001-000E, it means it cannot contact a network time server (NTP). This failure does not prevent you from printing, but the device's internal time will be incorrect, which affects log files and can desynchronize timelapse videos from the integrated camera. 🕒
Diagnose Local Network Issues
The origin of this error is almost always in your network configuration. The printer needs internet access to query the time using the NTP protocol, which uses port 123.
Steps to verify connectivity:- Confirm internet access: Check in the printer's menu if the Ethernet or Wi-Fi connection is active and stable.
- Test with another network: Connect the printer to a simple home network. This rules out corporate firewall blocks or restrictive configurations.
- Check the firewall: If you use a network with strict security, ensure that port 123 (NTP) is not blocked for the device.
A time server on the other side of the world can become inaccessible due to a simple firewall adjustment in your office.
Set the Time Manually
If the problem persists or you need an immediate solution, you can set the time manually, completely avoiding NTP synchronization.
Process to set manually:- Access the printer's settings menu and look for the Time and Date section.
- Disable the automatic NTP synchronization option.
- Enter the correct time and select your time zone manually.
Final Considerations on Synchronization
Setting the time manually resolves the error instantly, but it has a drawback: the time will not update automatically. If the printer loses power for a prolonged time or with summer/winter time changes, you will need to adjust the time manually again. This solution is a practical reminder that even the most advanced technology depends on network connections that can fail. ✅
