Upgrade your Creality printer with automatic bed leveling by installing a BLTouch probe. This smart sensor replaces the need for manual leveling by using a retractable pin to map your bed's surface with precision. This guide covers the complete installation process, including removing the Z-axis limit switch, mounting the probe with provided hardware, wiring connections for 32-bit mainboards (with specific pinouts for V4.2.2 and V4.2.7 boards), and updating firmware to enable auto-leveling functionality. We also cover critical steps like proper cable routing, verifying probe operation, and adding the G29 command to your start G-code.
