It delivers the single biggest advantage of steady first-layer results by automatically measuring bed tilt and compensating the Z axis, with advertised precision of +\/- 0.005mm. The kit focuses on compatibility and convenience: firmware can be upgraded via TF\/SD card and the sensor includes multiple mounting brackets for common Creality Ender and CR series models.\u003c\/p\u003e\n\u003ch2\u003eKey Features\u003c\/h2\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide compatibility:\u003c\/strong\u003e Works with Ender 3, Ender 3 V2, Ender 3 Pro, Ender 3 Max, Ender 5 and Ender 5 Pro when those machines have a 32 bit V4.2.2 or V4.2.7 mainboard, so owners of those models can add auto bed leveling.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEasy firmware upgrade:\u003c\/strong\u003e Firmware files can be copied to a TF\/SD card from the Creality official site and inserted into the printer to update without using an ISP burner, simplifying the update process.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMultiple mounting options:\u003c\/strong\u003e The kit includes three different brackets, allowing the small BL Touch sensor to be attached to several Creality printer frames without custom machining.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHigh precision leveling:\u003c\/strong\u003e The sensor claims enhanced leveling accuracy to about +\/- 0.005mm, enabling finer Z-axis compensation for more reliable first layers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAutomatic Z compensation:\u003c\/strong\u003e The probe measures bed inclination and automatically compensates the Z axis during prints, which helps avoid failures caused by uneven beds.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch2\u003eWho It's For\u003c\/h2\u003e\n\u003cp\u003eThis kit is aimed at Creality users who run one of the supported printers with a 32 bit V4.2.2 or V4.2.7 motherboard and who want a straightforward upgrade path to automatic bed leveling.
