What is the process of "first layer calibration"?

The process of first layer calibration involves adjusting the settings of a 3D printer to ensure that the first layer of the print adheres properly to the print bed. This is a crucial step in Fused Deposition Modeling (FDM) because a successful first layer sets the foundation for the entire print. If this layer doesn't adhere well, it can lead to warping, shifting, or complete print failure.

First layer calibration typically involves checking the printer's bed leveling, nozzle height, and possibly adjusting the extrusion temperature or speed for the filament being used. Properly calibrated first layers will ensure uniformity and a strong bond with the print surface, which is critical for achieving a high-quality final print.

The other options do not pertain to first layer calibration directly: the final layer color does not influence initial adhesion, determining print speed is a separate concern that affects overall efficiency rather than layer adherence, and printer interface setup pertains to user interaction rather than print quality.
