To adjust the print bed leveling on your 3D printer, follow these steps: Home the Printer: Make sure your printer is homed and in the home position before starting the bed leveling process. Disable Motors: Disable the motors so that the print bed can be manually moved. Use a Sheet of Paper: Use a piece of paper or a feeler gauge to check the gap between the print bed and the nozzle. Place the paper on the bed and move the nozzle down until it touches the paper. You should feel a slight resistance when moving the paper. Adjust the Screws: Use the leveling screws to adjust the gap between the print bed and the nozzle. If the gap is too large, tighten the leveling screw on that corner. If the gap is too small, loosen the leveling screw. Repeat the Process: Repeat this process for each corner of the print bed until the gap between the nozzle and the bed is consistent across the entire surface. Test Print: Once the print bed is leveled, perform a test print to ensure that the first layer adheres properly to the bed. If necessary, make further adjustments to the leveling until the first layer looks good. Save the Settings: Once you have successfully leveled the print bed, save the settings in your printer's firmware or in your slicing software so that you don't have to repeat the process every time you print. By properly leveling the print bed, you can ensure that your 3D prints will have a good foundation and adhere properly to the bed surface.
