<p>I have a Monoprice Maker Select Plus (Wanhao Duplicator i3 clone) and I'm having issued with the top layer of my prints. The bottom surface and the sides always come out perfect but my top layer is left with gaps in it. I have tried adjusting the print temperature, flow rate, print speed and layer height all with no success. I use Cura for my slicing software. If anyone knows how to help it'd be much appreciated</p>
