Possible root cause

  • Screw stripping because of the screw or screw hole. And causing the unstable position of the block that holds the platform.
  • Screws not tight enough on platform. Which will also cause the platform possition shifting.



How to confirm: 


  • Looking for evidence of the screw stripping.


  • Looking for loosen screws.


  • Looking for uneven status of platform.
