Creality Ender-3 V3 Plus CL2529 Z-Probe Error Traced and Fixed via Klipper Config

Users of the Creality Ender-3 V3 Plus 3D printer have been encountering a recurring CL2529 error during the initial Z-axis leveling step at the start of prints. Analysis of Klipper logs revealed that one of the four strain-gauge bed sensors (CH3) was producing erratic readings, causing inconsistent probe measurements and triggering a retry timeout. The error logic was traced through a compiled binary and later confirmed using GPL-licensed Python source code that Creality published in December 2025. The root cause is a built-in retry limit controlled by the tri_try_max_times parameter, which defaults to 10 and raises the error once exhausted. Setting tri_try_max_times to 0 in the printer.cfg file disables the check entirely, preventing the error from appearing without affecting print quality.
