Homing calibration needed

What happened? 

The printer is showing the message "Homing calibration is needed to ensure repeatable homing".

This warning indicates that homing calibration is required to ensure precise and repeatable homing of the printer axes. It typically appears when the printer loses positional accuracy, possibly due to mechanical interference.

Error name: Homing calibration needed

Error code: #31118 (CORE One) #35118 (CORE One L) #17118 (XL)

How to fix it? 

From the warning message on the printer screen, confirm the prompt to begin the homing calibration directly.

Observe the printer's movement:

• If all axes home smoothly and correctly, the warning should disappear after a successful calibration.
• If the printer moves erratically, struggles, or makes grinding noises, mechanical issues may be the cause.

If the homing fails, check the following:

• Belt tension: Ensure all belts are tight and not slipping. Adjust if needed.
• Pulley screws: Inspect the motor pulleys for loose grub screws that may cause slipping.
• Axis alignment: Verify that the axes move freely without resistance when powered off.
• Obstructions: Make sure nothing is blocking the movement of the print head or bed.

If the problem persists after inspection, do not hesitate to contact our technical support.
