Move the machine to a non-vibrating environment, and ensure not to touch the hot bed during homing, or follow the 2524 procedure. Move the machine to a non-vibrating environment, if the issue persists frequently, replace the product. 2531 G29 homing times exceed the limit, or timeout. Move the machine to a non-vibrating environment and ensure not to touch the hot bed during homing, or follow the 2524 procedure. Move the machine to a non-vibrating environment, if the issue persists frequently, replace the product. 2532 The synchronization wire between the two MCUs is not working properly (disconnected). Check if the leveling board plug is plugged in properly. Secure the plug, if the issue persists frequently, replace the product. 2533 In the case of CHECK_BED_MESH AUTO_G29=0, i.e., leveling is not allowed, but the hot bed does not match the leveling data. Re-level or configure AUTO_G29=1. Remotely modify the configuration file, or replace the product. 2534 The combined calculation of pressure data and step data is in error. Follow the 2524 procedure. If the issue persists frequently, replace the product. 2535 After leveling, the correctness of the points is checked. If it is still abnormal after multiple checks, an error is reported. Clean the hot bed, check the Z-axis movement status, and observe the measurement phenomenon of the nozzle at the four corners of the hot bed. Clean the hot bed, if the issue persists frequently, replace the product. 2560 Communication with the main MCU is abnormal. Communication with the subordinate machine is lost, and the host machine has not received data for more than 5 seconds. Check the wiring, restart. 2561 Communication with the nozzle MCU is abnormal. / Check the wiring, restart. 2562 Communication with the hot bed MCU is abnormal. / Check the wiring, restart. 2563 Communication with the rpi MCU is abnormal. / Check the wiring, restart. 2564 The nozzle is not heated as expected. The nozzle heating is turned on, but the temperature does not rise. Inspect the ceramic heating block, heat wiring, and terminal. Look for any damage on the ceramic heating ring, loose terminals, and heating rod seat. If damaged, contact customer service.
