Y-axis limit switch adjustment is way off on new Ender 3 V2 causing motor grinding noise and system lockup
It is possible that the buildplate is too low, and cannot travel all way down  the Y axis, but is hitting into the Y motor enclosure.
If you have screwed the Z-stop to printer's vertical frame, shifting the endstop all the way down, there is even bigger chance for this. So one advice is to raise the Z-stop by about a width of wrench key included to the set. Ender 3 V2 has a bit taller glass plate comparing to previous model.
That is not my idea, I just repeat that after the author of &quot;Tomb of 3D Printed Horrors&quot; youtube tutorials. The author also presented quick method Ender 3 easy bed leveling, including fine tuning of the Z-stop position.
Please also note, that there are wires with thermistor taped below the bed with crackling tape (probably capton). So if you raise it too few, you will regularly hear scraping and crackling sounds. Therefore before builtplate leveling, I would advice first to check the initial height if it is already safe.
