Your Bambu Lab Printer Warns That It Needs Maintenance on Its Axes

When the code HMS_0F02-0100 appears on your Bambu Lab printer, the firmware is clearly telling you: the X, Y, and Z axes have worked more than expected. This warning is preventive and its goal is for you to act before wear degrades your prints or causes strange noises. Ignoring it can cause mechanical components to fail prematurely. 🛠️

Understanding the Alert and Why to Act

The internal system keeps track of the distance traveled by the carriages. When a specific threshold is exceeded, it triggers this notification. It's not a critical error, but a service recommendation. Suppressing this message without acting compromises the precision and smoothness of movement, which are pillars for good 3D printing.

Materials needed for maintenance:
  • A lint-free cloth or microfiber rag.
  • Cotton swabs for hard-to-reach areas.
  • Appropriate lubricant, such as lithium grease or light machine oil, specific for linear guides or rods.
The machine is literally telling you to touch it and lubricate it. This is not the time to apply the philosophy "if it ain't broke, don't fix it."

Procedure to Clean and Lubricate the Axes

First, turn off and unplug the printer completely for safety. With the cloth, thoroughly clean all rods or linear rails to remove dust and old lubricant residue. Swabs will help in the grooves. Then, apply a minimal amount of new lubricant along each axis.

Key steps after applying the lubricant:
  • Manually move the print head (extruder) along the full travel of the X and Y axes.
  • Also move the build plate (Z axis) up and down several times.
  • This movement distributes the lubricant evenly and removes excess.

Reset the Counter in the Firmware

After completing the physical maintenance, it is crucial to reset the internal counter. From the touch screen, navigate to the settings menu. Look for the Maintenance or Mantenimiento option and within it, select Reset Maintenance Reminder. Confirm the action. This way, the system will start counting from zero and the warning won't reappear until the next cycle. This step ensures that the alert system remains useful for scheduling the next service. ✅
