Some test files to adjust your settings to get the perfect first layer. These will print 1 layer provided you are using a 0.2 mm layer height in your slicer settings. Then inspect your print and tweak one setting at a time until you get a perfect first layer as that is the most important layer.

Once you get a good result with the simple shapes, try the extreme test. If you can get that to print without any gaps, then you have a perfect first layer.
