How to Calibrate Your Extruder on a 3D Printer


3D printing technology is becoming increasingly popular, and with it comes the need for more technical knowledge. One of the most important things to understand when it comes to 3D printing is how to properly calibrate your extruder. Calibration of your extruder is essential for producing accurate 3D prints. Here is a step-by-step guide on how to calibrate your extruder on your 3D printer.

1. Pre-Calibration Preparation:

Before you begin the calibration process, you need to make sure that your 3D printer is properly set up. Make sure that your extruder and hot end are properly assembled and secured to the printer’s frame. Ensure that the filament is properly loaded into the extruder and that the filament path is clear of obstructions. If your 3D printer has a heated bed, make sure that it is properly leveled.

2. Set the Steps/Millimeter:

The next step is to set the steps per millimeter. This is the number of steps that the motor must turn in order to move the extruder one millimeter. You can find the steps per millimeter setting in the printer’s firmware. Once you have set this number, you can begin the calibration process.

3. Calibration:

Once you have the steps per millimeter set, you need to physically calibrate your extruder. To do this, you need to measure the distance that the filament moves when the extruder motor turns one full revolution. This can be done by carefully placing a piece of paper between the extruder and the nozzle(120mm), and then extrude 100mm. Measure the distance the filament has moved, hopefully 20mm is left behind. If not, then adjust the steps per millimeter setting until you get an accurate reading.

4. Test the Extruder:

Once you have the steps per millimeter set, you should test the extruder to make sure that it is properly calibrated. To do this, print a small calibration cube and measure its dimensions. If the dimensions are accurate, then your extruder is properly calibrated. If not, you may need to adjust the steps per millimeter setting and test again.

Calibrating your extruder is an important step in ensuring that your 3D prints are accurate. With a few simple steps, you can make sure that your extruder is properly calibrated and that your 3D prints will come out looking their best.
