Creality Official CR Touch Auto Leveling Kit for Ender 3/Pro/V2/Max/Ender 5 Review (2026)

What the CR Touch does

The CR Touch is an automatic bed leveling probe that measures the distance between the nozzle and the bed at multiple points across the print surface, then builds a mesh the printer's firmware uses to adjust the nozzle height in real time during a print. That removes the guesswork of manually leveling the bed with paper and a leveling knob at each corner, and it also compensates for a bed that is not perfectly flat, which manual leveling alone cannot fix. Creality specifies a positioning accuracy figure and a fast extension and retraction cycle for the probe pin, aimed at giving a repeatable trigger point at each mesh location.

Metal pin design

Unlike some third party probes that use a thin, somewhat fragile pin, Creality's CR Touch uses a metal push pin mechanism paired with a photoelectric sensor to detect the trigger point, and the design hides the spring internally to reduce the chance of losing or damaging it. Creality rates the pin for a very high number of extension cycles before wear becomes a concern, which matters since the pin extends and retracts at every single probe point on every leveling pass, adding up to thousands of cycles over the life of a printer. The metal construction is generally more resistant to the knocks and scrapes that can happen if a probe gets bumped during handling or a failed print.

Mainboard and firmware requirements

Creality's official CR Touch kit specifically targets printers running a 32 bit V4.2.2 or V4.2.7 mainboard, since the wiring, connector layout, and firmware support Creality builds for this probe are matched to those boards. Printers still running an older 8 bit mainboard, common on earlier production runs of the Ender 3 and Ender 3 Pro, typically need a board upgrade or a compatible third party firmware build before the CR Touch will function correctly, since the stock 8 bit firmware generally lacks the auto leveling support these newer boards ship with. Checking the mainboard version before ordering avoids buying a probe that cannot be wired in without further upgrades.

Installation and setup

Setting up the CR Touch involves mounting the probe bracket near the nozzle, wiring it into the mainboard's dedicated probe connector, and loading Creality's provided firmware onto the printer via SD card, which enables the auto leveling menu and probing routine. Creality provides firmware files matched to its supported models, but mount orientation and bracket position can vary slightly between the Ender 3, Ender 3 Pro, Ender 3 V2, Ender 3 Max, and Ender 5, so following the specific installation guide for the exact printer model rather than a generic guide avoids probe height or wiring mismatches during first setup.

Who should buy this

This is a strong pick for anyone with a compatible 32 bit board who is tired of manually releveling the bed before every print, or whose bed has enough physical warp that manual leveling alone cannot produce a good first layer everywhere. Being an official Creality part also means the firmware and mounting hardware are built specifically for the listed models rather than adapted from a generic probe design. It is a weaker fit for owners of older 8 bit board printers who are not prepared to also upgrade their mainboard or flash third party firmware, since the probe alone will not function on unsupported boards.
