@doron 202 alarm is homing failed. This alarm is the prompt message that the printer failed to reset successfully within a limited time during homing. 1. Therefore, please use the axis movement parameters first to control and check out whether the XYZ axis works normally. 2. Check the pressure-sensitive function, whether the Z-axis limit switch can trigger normally, and whether the red lamp goes out. 3. Whether the blue lamp of the adapter plate lights up when the nozzle pressure is felt.
