What the Creality BLTouch 32-bit kit does

The Official Creality BLTouch Auto-Bed Leveling Sensor Kit - 32bit is an electronic bed levelling upgrade for compatible 3D printers that measures the tilt of the print bed surface with high precision. The kit uses an ANTCLABS BLTouch V3.1 probe and is designed to improve bed probing accuracy across different build surface materials.

This BLTouch is a type of semiconductor hall sensor used in 3D printers. Its purpose is to automate bed levelling measurement so the printer can detect surface tilt more precisely before printing.

Important: This kit is intended for the Ender 3 Series and Ender 5 Series with V4.2.2 or V4.2.7 mainboards. The official Creality Ender 6 BLTouch kit is a separate product.

BLTouch features and operating functions

The BLTouch provides the main functions and controls expected from a standard auto bed levelling sensor while using a structure based on an RC servo and microswitch. Because of that design, the BLTouch can be applied on almost every board, while this Creality kit is specifically intended for the compatible 32-bit Creality board versions listed above.

The probe combines a progressively designed solenoid with a hall sensor to deliver a simple structure and high precision. The design focuses on practical operation and adds smart diagnostic and control functions that help with setup and troubleshooting.

• Precise bed tilt measurement: Detects the tilt of the bed surface for more accurate levelling.
• Works with multiple bed materials: Suitable for surfaces such as glass, wood, and metal.
• RC servo and microswitch control: Uses a familiar auto levelling sensor control approach.
• Simple structure with high precision: Combines solenoid and hall sensor design for reliable probing.
• Self-test function: The push pin operates two times when the power is on.
• Alarm function: The LED light blinks if a problem is found during self-test or operation.
• Alarm release and Touch Switch mode: Included as part of the BLTouch smart function set.
• Blue LED servo signal indication: Shows servo signal status.
• Z-probe (Zmin) testing: Supports Z-probe testing during setup and verification.
• Wiring defect indication: Blue and Red LEDs indicate wiring defects.

Where this auto-bed levelling sensor is useful

This BLTouch kit is useful for Ender 3 and Ender 5 owners who want automatic bed tilt measurement on printers with Creality V4.2.2 or V4.2.7 32-bit boards. It is especially relevant when the printer uses different bed surface materials and manual levelling consistency is a concern.

The sensor is also useful when troubleshooting probe setup, because the built-in self-test, alarm indication, servo signal light, and wiring defect indicators provide direct status feedback during installation and operation.
