Nozzle sporadically crashing into bed while homing or Z_tilting #148

I have a BDsensor ordered in December 2023 with the following output: BDsensorVer:V1.2 pandapi3d.com ,switch_mode=0,collision_homing=0,collision_cal=0

Yesterday I updated all my Klipper related components with BDSensor to: 20230524-277-g80560a37 Now when performing home or especially Z tilt the nozzle often crashes into the bed and already destroyed the PEI sheet.

I found your post here where you instructed to update the firmware in such a case: https://github.com/markniu/Bed_Distance_sensor/issues/109#issuecomment-2024361586

Is this error documented somewhere?

I guess this is hardware version 1.3 so I need the STM Flasher? 20240602_183605

I am so sorry for that damage.
right, this is the latest hardware version, you can flash the latest firmware with stlink: https://github.com/markniu/Bed_Distance_sensor/wiki/Flash-BDsensor(stm32)-firmware the latest firmware of BDsensor is V1.2c that let the sensor works as normal proximity sensor while probing and support nozzle collision sensing. and also use this macro for z_tilt: https://github.com/markniu/Bed_Distance_sensor/wiki/Z-move-or-not-automatically_Z_Tilt_QGL that will be more safe and quick.
