Ender 3 with BTT skr mini 2 board knocks

I installed the latest marlin for my Ender 3 with skr mini 2 board and now I hear a knock as when the x and y axis move. It almost sounds as though something is being hit. But I’ve looked all over the machine and tested the axis when turned off and nothing is binding or hitting anything. I reverted back to the original Marlin and the sound goes away. Is there a setting that needs to be changed?
