<p>Just received my new Ender 3 v2. When using the Auto Home feature, the Y-axis motor drives the bed as far back as possible then the motor grinds for about 10-15 seconds. The Y-axis limit switch is not being depressed and the limit stop is about .5 inches away from the switch. The control unit locks at this point and must be power cycled to regain control. If I manually depress the limit switch then it appears to act normally.</p>
<p>Clearly either the limit switch is way out of adjustment or the bed is not positioned properly. Can this be fixed or should I send it back as defective?</p>

You could still get heat creep with a Bowden tube.  It has different characteristics.  Instead of jamming up in the direct drive, the filament can melt too far upwards into the heat break where it can refreeze and jam.  The characteristic, if you can pull out the filament, is widened filament extending into the heat break.
