<p>I´ve been using my Ender 3 Pro for almost 1 year now. Always using the provided SD card. For a couple of days, the printed does not read any new file that I load to the SD card, but it does with the older files (and it then prints correctly as well).</p>
<p>I tried deleting some old files that I don't need, I tried turning it on with the SD card, I tried inserting the card after turning the printer on. It's always the same.</p>
<p>I am using another SD card and it works properly.</p>
<p>Any idea?</p>

If this is the actual problem, of fiddling with the cables might have caused this, an alternative solution is presented as I\'ve experienced similar behavior.</p>\n<p>If one side of the bed is higher than the rest, even when rotating the glass bed, you might experience that the nozzle carriage is tilting on that side. E.g. when using a Bowden extruder assembly, a too short Bowden tube (or cables in a non-Bowden setup) the tube (or cables) pull at the carriage causing it to lift at the furthest points from the extruder; this tilting can cause the nozzle to go up a few tenths of a millimeter.</p>\n'}]
