Creality 4.2.7 board - BL touch socket for Klicky probe

General Discussion

Sure, you can find the schematic here: Creality Board 4.2.2 and 4.2.7 Schematics

Klipper only allows to, EITHER:

  1. Probe used for endstop and probing purposes
  2. Use the endstop for endstop purposes and the probe for probing purposes

Combining both with kind of a redundancy is not possible, so you may as well use Z-min.
