Introduction

Creality CR Touch has been proven perfect by the 3d printing community, the high leveling precision, stability, silent auto-leveling, and durable metal probe were admired again and again by the users.

Why need CR Touch Auto Leveling Sensor

 We can often see that people complain that they are tired of manual leveling before every print. That's why people love to install an auto-leveling sensor on their printers. Auto leveling is a big time saver and makes printing much more enjoyable. At the first time using the CR Touch, make sure you start off with an approximately leveled bed (with paper) and the probe does the rest. Don't forget to set your probe Z offset by following the manual. Then no need for manual leveling later.

Why Choose CR Touch

• Metal probes, more durable, can be reused more than 100,000 times. It never gets stuck, and it is extremely accurate.
• The higher degree of precision. 0 04mm of accuracy is officially claimed, 0.02mm is about average, sometimes 0.01mm.
• Easy to install, and comes with 3 different mounts. ( After installation, please download the CT Touch firmware from the Creality official website and flash the firmware.)
