Hello,

I install FW Ender 3 - SKR-Mini-E3-v3-BLTouch-20230516.bin and when i try to print stringing tower i can hear weird sound after head is moving from one side to another. It is like something is hit. Then i try install back FW from BIGTREETECH-SKR-mini-E3 and noise disappier.

My HW - Ender 3, SKR MiniE3v3, BLTouch, BiquH2V2
