I recently gave my CoreXZ a test print to try and see if some previous issues were resolved, however when I gave it the print, the nozzle was an inch or two above the bed, then when I tried to stop it, the head lowered and attempted to continue lowering onto the bed itself, scratching it a ton. One error that has popped up a few times is “CL2533: The level sensor may experience external interference” However no matter how hard I look I see nothing that even eludes to this error code existing in the first place. Please send help!
