Ender 3 Auto Bed Leveling Kit CR Touch - Reliable Auto Bed Leveling

In this review of the Ender 3 Auto Bed Leveling Kit with the official CR Touch, the bottom line is simple: this upgrade is for Ender 3 and CR-10 owners who want accurate, low-effort first layers. Installation includes the sensor, three mounting brackets and silicone mounts so the kit arrives with everything needed for a clean install on printers with 32-bit V4.2.2 or V4.2.7 mainboards. The prominent advantage is the sensor's multi-point compensation that builds a virtual plane and reduces manual fiddling, making it the single biggest reason a regular printer user would add this kit.

Key Features

• Automatic Leveling: The CR Touch performs multi-point detection of the build surface and calculates distance compensation to keep the nozzle at the right height during prints.
• Long Service Life: The combination of optical and metal probes is designed to extend durability compared with earlier probe designs and reduce field-related errors.
• Strong Compatibility: The kit includes three brackets and fits a wide range of Ender 3 and CR-10 models using 32-bit V4.2.2 or V4.2.7 boards, avoiding custom bracket fabrication.
• Silicone Mounts: Four silicone column mounts help the probe retain level after a single accurate setup so you rarely need a full manual relevel.
• Complete Package: The box contains the CR Touch, three mounting brackets, silicone mounts, power cord, tie straps and screws so users can start firmware installation right away.
• After-sales Support: The seller provides 24-hour online after-sales service and technical help for installation and troubleshooting.

Who It's For

This kit is aimed at hobbyists and small workshop users running Ender 3 series or CR-10 printers with 32-bit V4.2.2 or V4.2.7 mainboards who want to eliminate repetitive manual bed adjustments and improve first-layer consistency. It suits people who already understand basic firmware flashing and hardware mounting since the install requires copying firmware to a blank SD card and rebooting the printer.

It's less suited to users with older 8-bit motherboards, printers outside the listed models, or those unwilling to update firmware; such users should look for a probe explicitly compatible with their control board or seek a vendor-offered firmware image for their board variant.

Pros & Cons

Pros

• Strong, consistent bed leveling from multi-point detection greatly improves first-layer success rates.
• Includes all necessary brackets and mounts for supported Ender and CR-10 models, simplifying installation.
• Durable probe design and silicone mounts reduce the need for frequent re-leveling.
• 24-hour after-sales support helps with setup and troubleshooting.

Cons

• Firmware update and SD card installation are required, which can be a hurdle for novices.
• Only compatible with printers using 32-bit V4.2.2 or V4.2.7 mainboards; not universal.

Specifications

Our Verdict

The Ender 3 Auto Bed Leveling Kit with CR Touch is a practical upgrade for owners of supported Ender and CR-10 models who want more reliable first layers and less manual adjustment. It delivers consistent multi-point leveling, durable hardware and a complete mounting kit at sensible value, though it assumes the buyer can perform a firmware update on a 32-bit board.
