How do you calibrate your dual extruder for optimal alignment and quality?

1 Why calibrate your dual extruder?

Calibrating your dual extruder is essential to avoid issues such as oozing, stringing, blobs, gaps, and misalignment. These problems can ruin the appearance and accuracy of your prints and waste your filament. By calibrating your dual extruder, you can ensure that both nozzles are at the same height, have the same temperature, and move in sync. You can also fine-tune the distance and angle between the nozzles to match the dimensions of your model.

3 How to calibrate the height of your dual extruder?

The first step to calibrate your dual extruder is to adjust the height of both nozzles. This will ensure that they are at the same level and print evenly. To do this, you need to heat up both extruders and load some filament. Then, you need to move the print head to the center of the bed and lower it until it touches the paper. You can use the paper as a gauge to check the resistance of the nozzles. If one nozzle is higher or lower than the other, you need to loosen or tighten the screws that hold it in place. Repeat this process until both nozzles have the same resistance.

5 How to calibrate the quality of your dual extruder?

The last step to calibrate your dual extruder is to test and improve the quality of your prints. This involves adjusting settings in your slicer or firmware, such as retraction, temperature, and speed. Retraction is the amount of filament that’s pulled back into the nozzle when switching between extruders, and it helps prevent oozing and stringing. Temperature affects the flow and adhesion of the filament, while speed affects accuracy and smoothness. To calibrate the quality of your dual extruder, you need to print a calibration model with different shapes and colors. Examine the print for any defects or imperfections, then modify the settings until you get a satisfactory result.
