How to use
Power down the printer and disconnect it from mains before beginning any work. Remove the printer covers as needed to access the existing mainboard and carefully document or photograph wiring and connector positions. Disconnect cables one at a time, noting their locations, then remove mounting screws and extract the old board. Install the replacement board into the original mounting points, secure with screws, and reconnect each cable to the matching connector. Verify thermistor, heater, stepper and fan connectors are correctly seated. Reassemble covers and reconnect mains power. Power on the printer and confirm that boot, display and basic functions operate normally; run an axis homing sequence and a temperature readout check before starting a print.
Usage recommendations
Use original BambuLab firmware or manufacturer-recommended firmware versions for this board to preserve sensor calibration and safety features. If any connectors appear damaged or pins are bent, replace cables or repair contacts before use. Perform an initial calibration sequence and a low-temperature test print to verify proper operation after replacement.
