[BUG] Ender 5 w/ BL Touch - HOMING FAILED, PRINTER HALTED, Please reset - bugfix-2.1.x only

Bug Description

When using version bugfix-2.1.0, as I auto home on an Ender 5 printer with a BL Touch, I encounter an error "HOMING FAILED, PRINTER HALTED, Please reset". Even though everything went well (motor stops after encountering probe).

Configuration Files

DEFAULT_ENV : STM32F103RE_creality
confs.zip

Steps to Reproduce

BL Touch is wired using the 5 to 5 pin connector, so no possible wiring mistake.
BL Touch is genuine from Creality, not a clone.

If I use bugfix-2.0.0, everything works fine with the exact same changes (wished I tried sooner 🥲).

Relevant configuration changes :
Creality Ender 5 - V427 preset

#define USE_PROBE_FOR_Z_HOMING
//#define Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN
#define BLTOUCH
#define NOZZLE_TO_PROBE_OFFSET { -44, -9, 0 } For Use with Stock BL Touch Brackets
#define AUTO_BED_LEVELING_BILINEAR
#define Z_SAFE_HOMING

#define BLTOUCH_DELAY 500
#define BLTOUCH_FORCE_SW_MOD

What I tried :

  • Plugged or Unplugged zstop sensor -> nothing changed (I updated Z_MIN_PROBE_USES_Z_MIN_ENDSTOP_PIN as I made these tests)

Expected behavior:
The error should just not appear as everything went well.

Actual behavior:
Error displays and I cannot print anything.

Hello,
I figured out that this screen only pops when I manually trigger the bltouch probe as part of the homing process. I guess the firmware did not recognize it as a standard hit and more as a physical obstruction, if that makes sense.
That was it.

And thanks, I will know for the next time.
