- A cleaning brush or cloth
It is important to note that the specific tools you need may vary depending on the type of 3D printer you have. Be sure to check your printer’s user manual or manufacturer’s website for any additional tools or materials that may be required.
Once you have gathered all the necessary tools and materials, you can move on to the next step, which is to check the printer’s hardware and software. This involves verifying that the printer’s firmware is up to date and that all the hardware components are working correctly.
In the next section, we will discuss how to check your 3D printer’s hardware and software to ensure that it is ready for calibration.
Calibrating the Extruder
Calibrating the extruder is an essential step in achieving high-quality 3D prints. It involves measuring the filament diameter and updating the extruder steps per unit value to ensure that the printer is delivering the correct amount of plastic.
Measuring the Filament Diameter
Before calibrating the extruder, it is essential to measure the filament diameter accurately. The filament diameter can vary from one spool to another, and even within the same spool. Therefore, it is crucial to measure the filament diameter at several points along the spool and calculate the average.
To measure the filament diameter, use a micrometer or caliper. Measure the filament at several points along the spool, and record the measurements. Calculate the average of the measurements to get the filament diameter.
Updating the Extruder Steps per Unit Value
Once you have measured the filament diameter, it is time to update the extruder steps per unit value. The extruder steps per unit value tells the printer how many steps the extruder motor needs to take to push a specific amount of filament through the nozzle.
To update the extruder steps per unit value, follow these steps:
Connect your printer to your computer and open your printer software.
Heat up your hotend to the printing temperature.
Mark the filament 120mm away from the extruder.
Use your printer software to extrude 100mm of filament.
Measure the distance between the extruder and the mark on the filament. This distance should be 20mm.
If the distance is different, use the following formula to calculate the new extruder steps per unit value:
New steps per unit value = (Current steps per unit value x 100) / distance
For example, if your current steps per unit value is 100, and the distance is 25mm, the new steps per unit value would be:
New steps per unit value = (100 x 100) / 25 = 400
Update the steps per unit value in your printer software and save the changes.
By following these steps, you can calibrate your extruder and ensure that your printer is delivering the correct amount of plastic.
Calibrating the Bed
Calibrating the bed is an essential step in achieving high-quality 3D prints. Bed leveling ensures that the first layer of the print is properly adhered to the print bed, which is crucial for the success of the entire print. There are two ways to level the bed: manual bed leveling and auto bed leveling.
Manual Bed Leveling
Manual bed leveling is a straightforward process that involves adjusting the print bed’s height manually. The process requires a piece of paper, which is used to measure the distance between the nozzle and the print bed. Here are the steps to follow:
- Heat the bed and nozzle to the desired printing temperature.
- Move the print head to the center of the bed and lower it until the nozzle is almost touching the bed.
- Slide the piece of paper between the nozzle and the bed.
- Adjust the bed height until there is a slight resistance when pulling the paper out from under the nozzle.
- Repeat the process for all four corners of the bed.
- Check the center of the bed and make minor adjustments if necessary.
Auto Bed Leveling
Auto bed leveling is a more advanced method that uses sensors to detect the distance between the nozzle and the print bed. The process requires a sensor, which is attached to the print head and connected to the printer’s control board. Here are the steps to follow:
- Install the sensor and configure it according to your printer’s instructions.
- Heat the bed and nozzle to the desired printing temperature.
- Run the auto bed leveling process from your printer’s menu.
- The sensor will probe the bed at multiple points and generate a mesh that compensates for any unevenness in the bed.
- Save the mesh to your printer’s memory.
Auto bed leveling is more accurate than manual bed leveling and saves time by eliminating the need to adjust the bed manually. However, it requires additional hardware and may not be compatible with all printers.
In conclusion, bed leveling is an essential step in achieving high-quality 3D prints. Whether you choose manual bed leveling or auto bed leveling, make sure to follow the instructions carefully and adjust the bed until the first layer adheres properly.
Fine-Tuning the Calibration

One of the best ways to fine-tune your printer’s calibration is to do some test prints. There are many test prints available online that can help you identify specific issues with your printer’s calibration. For example, a calibration cube can help you determine if your printer is over or under-extruding, while a bridging test can help you identify issues with your printer’s cooling settings.
Adjusting the Printer Settings
Once you have identified the specific issues with your printer’s calibration, you can adjust the printer settings to address them. Here are some common adjustments you may need to make:
- Extrusion multiplier: If your printer is over or under-extruding, you may need to adjust the extrusion multiplier setting in your slicer. This setting controls how much filament is extruded during printing.
- Z-offset: If your first layer is not sticking properly to the print bed, you may need to adjust the Z-offset. This setting controls the distance between the print nozzle and the print bed.
- Cooling settings: If you are experiencing issues with stringing or oozing, you may need to adjust your printer’s cooling settings. This can help prevent excess filament from being deposited on the print.
Fine-tuning your printer’s calibration can take some trial and error, but with some patience and persistence, you can achieve excellent results. By doing some test prints and adjusting your printer settings, you can address specific issues with your printer’s calibration and achieve high-quality prints.
