When I do self check I get error 2522
Hello @wayne_levesque …! 
Welcome to the Creality Forum…! 
I believe it has something to do with the leveling sensors. If you do a search for “error 2522” there should be some discussions about it on this forum.
I’ve had that error before on my machine when it was new. It hasn’t done it since for some reason after firmware updates and some resets.
If you are doing a calibration and notice the bed start to go all the way down (not supposed to do that) to the bottom shut the machine off.
When mine did that it would come back up and the nozzle would crash into the build plate…
