<p>I just got a new Ender3 version two for Christmas and was very excited to use it so I put it together and used the sample filament that came with the printer and everything worked okay for a bit.</p>
<p>That was until I switched something in the settings, or in Cura, or something happened, because the nozzle is too far away from the bed when printing. I will use the auto home feature to level my bed with a piece of paper and once I get that pretty close I try and start my print, and it starts a few millimetres further away from the bed than when levelling it.</p>
<p>Any ideas to solve this?</p>

This is probably caused by too few top layers in combination with a too low infill percentage. Increase skin layers and increase infill percentage.
If you have multiple layers already (at least about 4 for 0.2 mm layer height, for smaller layer heights even more), you might be printing at a too high temperature and or too few part cooling percentage and a too low infill percentage.
