Fully Calibrate Your Bed Level:
Many problems can be eliminated by having an accurately leveled bed. Depending on which printer you have there may be multiple steps required to level the bed.
Several of the common terms related to bed leveling are not the same thing and requires you to know when to apply each:

Bed Tramming (Paper Resistence Test):
Bed tramming is the manual process of leveling the 3D printer's build plate to ensure it's parallel to the printer's X and Y axes. It typically involves adjusting leveling screws or knobs at multiple points on the build plate. The goal is to create a level and even surface to improve adhesion and print quality.
Z Offset Adjustment (Z Offset value, Home Offset value, Z-axis Comp):
Z offset adjustment is a calibration setting that fine-tunes the starting distance between the nozzle and the build plate, accounting for differences in distance from printer to printer. However, it does not compensate for variations in the build plate's surface, which may still require manual leveling.
Mesh Leveling (CR-Touch, BL-Touch):
Mesh leveling, also known as automatic bed leveling, uses sensors to create a detailed height map of the entire build plate. It dynamically adjusts the nozzle's height during printing to account for unevenness in the build plate. This process helps maintain a consistent nozzle-to-bed distance and improves adhesion across the entire print surface.
