First layer 15x15cm

thingiverse

People often recommend setting a Z offset of 0.3mm and 0.2mm to achieve ideal results, paired with a print area of 15cmx15cm. For improved bed adhesion, printing at 90% height is generally a good idea. In the case of a 0.2mm layer, using a nozzle size of 0.18mm typically yields the best results. Similarly, for a 0.3mm layer, a nozzle size of 0.27mm usually produces the most desirable outcome.
