Screen shows gibberish and z homing only one side

Hello @cfg,

@cfg

screen starts showing gibberish after a few moves in the menu.

Using a SKR Pro board? If so, is the JST shield for the TFT’s serial cable removed to help serial cable make better connection?

@cfg

homing z axis only 1 side homes. Both move when I independently move the z axis
