This prompt indicates that the flow proportional calibration pattern has been printed, but the camera has failed to recognize the pattern correctly or the recognized value is out of range, so the calibration has failed and the system will automatically use the default printing parameters.
Check nozzle camera recognition: Make sure the camera is barrier-free, check that the lens is clean, and the shooting angle is suitable for identifying calibration patterns.
Confirm the quality of the pattern: Ensure that the calibration pattern is clear and meets the requirements, without blurring or damage.
Adjust the ambient light: Ensure that the print environment is well lit to improve the recognition of the camera.
Step 1: Check the integrity and clarity of the calibration pattern.
Step 2: Clean the nozzle camera to make sure there is no dust or bo blockage
Step 3: If the problem persists, re-print the calibration pattern and calibrate the flow ratio again.
