Description

Z-Endstop on Chitu V8 boards seems to remain in triggered state after pressed once and released. As such this makes it impossible to home Z properly or print. A workaround has been found by utilizing the unused z-max pin. This can be done by swapping the Z endstop switch from z-min to z-max on the board, then modifying Marlin/src/pins/stm32f1/pins_CHITU3D_V5.h and changing #define Z_STOP_PIN from PA14 to PA13.

Research direction

Start with Marlin/src/pins/stm32f1/pins_CHITU3D_V5.h and inspect the Z_STOP_PIN definition for the TRONXY Chitu V8 board. Compare the documented z-min and z-max workaround, then verify that the selected pin reports released and triggered states correctly during Z homing.
