I have a ender 3 v3 se, while making a print the screen froze up and I could not get it to unfreeze. After tinkering around I decided to replace the motherboard (c14 same as what I have) and reflash the software and it seemed to work . Here’s the issue now. 1. I turn on the printer, and it loads past the creality logo and then to the langue selection. After I select that, it does what it does until it looks like it will run the initial bed level. The screen changes to the empty square and goes to take the first probe. It touches the bed once then restarts the bed leveling. I have checked everything ( I can think of) changed the cr touch and the wiring harness and still have this issue. The only thing left to change is the ribbon cable. I have rechecked the connections to the motherboard twice. I am currently at work and cannot try any changes right now, but any ideas will help
Check if your probe unit is tightened as it should on the bars. If it’s loose it may give you errors or cannot calibrate.
