What Is Baby Stepping?

Baby stepping is a technique used to fine-tune the level of the print bed in a 3D printer during the printing process. It involves making small adjustments to the position of the bed, typically by turning a knob or adjusting a screw, in order to improve the accuracy of the print. This technique is often used to ensure that the first layer of the print adheres properly to the bed and that the printer is able to lay down the plastic filament smoothly and evenly.
Many 3D printer firmware programs support baby stepping, including Marlin, Repetier, Duet3D and Smoothieware. These 3D printer firmware programs allow users to manually adjust the bed level during the printing process in order to achieve better print quality. In general, baby stepping is an important technique for ensuring that 3D prints are accurate and have a good surface finish.
