Bed Leveling
Leveling the bed of a 3D printer is an essential step to ensure proper adhesion and accurate printing. Even with Auto Bed Leveling, it is the most essential and primary step in ensuring a good printer.
Here's a guide on how to level a 3D printer bed using the paper method:
Home the Printer: Start by homing the printer, which will position the nozzle at its starting point.
-
Disable Stepper Motors: Disable the stepper motors so that you can manually move the print head without resistance.
For Klipper, it's this button
Caution: Printers with BL Touch or Self-leveling
Preset the Z to 0.0 when doing this method before disabling the motors
Move the Nozzle: Manually move the print head to each corner of the bed using the printer's control panel or software. Ensure that the nozzle is positioned directly above the corner. Place a Sheet of Paper: Take a sheet of standard printer paper or a thin gauge feeler gauge. Slide it under the nozzle while adjusting the bed height. The paper should have a slight resistance when moving under the nozzle.
- Adjust the Bed: Use the printer's bed leveling knobs or screws to adjust the bed height. Rotate the knobs or screws incrementally to raise or lower the bed until you achieve the desired resistance on the paper. Repeat for Each Corner: Repeat the process of placing the paper and adjusting the bed height for each corner of the bed. Ensure that the nozzle is at the same height above the bed in all corners.
Check the Center: After leveling the corners, check the center of the bed by sliding the paper under the nozzle at the center point. It should have a similar resistance as at the corners. If necessary, adjust the bed height in the center.
- Recheck and Fine-Tune: Repeat the leveling process a few times, going through each corner and the center, until the paper slides with a consistent resistance throughout.
Leveling the bed is an iterative process that may require adjustments over time as the printer settles or when switching print surfaces. Regularly check

Prohibited Printing Filaments
For the Bambu P1P 3D printer without an enclosure, we've created a list of materials that are not recommended due to the printer's open design and the need for proper ventilation and temperature control:
-
ABS (Acrylonitrile Butadiene Styrene): ABS is known for emitting potentially harmful fumes and requiring high temperatures for proper printing. These conditions are difficult to maintain without an enclosure, which can result in warping and poor air quality.
-
ASA (Acrylonitrile Styrene Acrylate): Similar to ABS, ASA also emits fumes during printing and requires high temperatures that are best managed in an enclosed environment.
-
PC (Polycarbonate): PC needs very high printing temperatures and is susceptible to moisture absorption, which can negatively impact print quality. Enclosures help maintain the necessary temperature and protect the material from environmental factors.
-
Nylon: This material is tough and flexible but also requires high temperatures for printing. It absorbs moisture from the air, which can degrade its quality and performance without proper storage and printing conditions.
-
HIPS (High Impact Polystyrene): Commonly used as a support material with ABS, HIPS requires similar printing conditions, including a heated environment to minimize warping, which is typically achieved with an enclosure.
Each of these materials presents specific challenges when used without an enclosure, such as the need for stable high temperatures and controlled ventilation to manage fumes and ensure print quality. When selecting filaments for the Bambu P1P, it's crucial to consider these factors to maintain safety and achieve optimal results (3DSourced) (Printing It 3D) (Manufacturing on Demand) (Wevolver).
