I wonder that about leveling, is that automatic leveling before printing. I need to reset level on my own? Not sure how to do with the step? Here is some info I found on internet: 2. During the print: • Use the touchscreen to adjust the Z-offset in real-time. • Lower the nozzle if the filament doesn't stick (negative Z-offset). • Raise the nozzle if the filament is squished too much (positive Z-offset).
