The auto leveling system for a 3D printer refers to the average position of the print bed relative to the printer's nozzle. Auto leveling is a process that ensures the print bed is level and at a consistent distance from the nozzle across the entire printing area. This is important because if the print bed is not level or the distance between the nozzle and bed is inconsistent, it can cause printing problems such as uneven layers, adhesion issues, or even nozzle crashes.
The mean of the auto-leveling system is typically determined by taking multiple measurements of the distance between the nozzle and the print bed at various points across the bed surface. These measurements are then used to calculate the average position of the bed relative to the nozzle, which is used as a reference point for printing.
Many 3D printers come with built-in auto leveling systems, which use sensors or probes to measure the distance between the nozzle and bed and automatically adjust the bed height as needed during printing. This can save time and effort compared to manual bed leveling, and ensure consistent and high-quality prints.
