When we first started using our Cube 2, we thought that the leveling command would actually make and save adjustments. We learned that this command's purpose is only for checking the gaps, and does not make any changes.

We found that having the corners of the print pad at different heights contributed to an uneven thickness of the filament on the first layer. The tip was not running parallel to the print pad. Because of this, the tip would come too close to the pad in the areas where the gap was small, which caused a thinner strip to be laid down. We think this may have also contributed to the filament flow error that appeared multiple times. Eventually, it got to the point where every print attempted would fail.

Because of this, we tried to level the print pad according to the instructions. We were either very confused or the instructions were not adequate, so we looked at how it was built and figured out a way to fix this problem that worked for us.

First off, notice the print pad is mounted by three fasteners, however one of them is not adjustable (it has a solid spacer). The other two have nuts above and below the black mounting plate. In order to make an adjustment to one fastener, you will need to loosen/tighten both of the nuts. For example, if the gap at the front of the pad is too large, you would need to adjust the front screw. In this case, you would need to loosen the top nut first, and then tighten the bottom nut, which raises the pad.

This process is very tedious because multiple iterations are required. After each adjustment, you need to check the gap for all four corners, and then repeat the process between the two fasteners until the pad is level. We found it easiest to leave the tip in one corner, make adjustments for it, and repeat for each corner.

After levelling the pad, we experienced no further print failures, and the quality of the parts improved.
