CR Touch is a Creality 3D research institute self-developed 3D printer platform leveling solution based on hundreds of millions of users' data used by the creators. Compared with the traditional automatic leveling, it is compatible with more 3D printer platforms, more stable, and cost-effective. CR Touch is upgraded to a metal probe, which reduces wear and tear and greatly prolongs its service life. Download the CR Touch program from the Support Center and copy it to the TF/SD card. Insert it directly into the card slot of the 3D printer. The program can be updated after power on.
