Klipper Pressure Advance Tips: Get the Best of Your 3D Printer

The Klipper firmware is a powerful tool that can supercharge any 3D printer. One of its most impressive features is the Pressure Advance function. This feature enables you to optimize your printer’s performance and reach higher speeds while printing.

In this post, we will show you some of the best Klipper Pressure Advance tips that will help you unleash your printer’s full potential. So, if you want to improve your print quality and speed, stick around and read on.

Understand What Pressure Advance Is

To get the best out of Klipper Pressure Advance, you first need to know what it is. Pressure Advance is a feature that alters the printer’s extrusion system to compensate for the inherent resistance of the filament. This compensation fine-tunes the pressure in the nozzle to reduce over-extrusion and improve print quality. Therefore, to use this function, you must measure the pressure needed to extrude every kind of filament. This means tweaking the pressure advance values for each material until you get the best print quality.

Use the Correct Measurement Tools

Measuring the pressure needed to extrude the filament accurately is critical when using Pressure Advance. Therefore, you should ensure that you have the correct measurement tools before starting. One of the best devices for measuring pressure is the filament force sensor. It accurately measures the force required to extrude the filament and allows you to tweak the Pressure Advance values to get the best print quality. You can also use a ruler and calipers to measure the filament’s diameter and adjust the values accordingly.

Start with Low Values

When starting with Pressure Advance, it is essential to begin with lower values and gradually increase them. A too high value could create issues, such as under-extrusion, stringing, or even nozzle clogs. Therefore, start by trying a 0.05 value and gradually increase it by 0.05 until you notice a difference in print quality. A rule of thumb is that higher values of Pressure Advance cause faster and better printing with less coasting, but also increase the risk of under-extrusion.

Fine-Tune the Pressure Advance

Even after setting up the Pressure Advance values, you may need to fine-tune them continuously. This is especially true if you want to use different filaments or print models with different shapes or weights. Fine-tuning the values involves experimenting with different settings and observing the results. You can do this by printing calibrating models or designs specifically to test the pressure advance. By continuously fine-tuning the values, you will get the best print quality with minimum under-extrusion and stringing.

Add Pressure Advance to Your Start G-Code

As a final tip, it is always a good idea to add the Pressure Advance values to your start G-code. This way, you won’t forget to set them up, and you can link them to different slicer profiles. It also makes it easier to fine-tune the values as you can observe the differences in print quality easily. Adding them to your start G-Code tends to be more convenient, but you can also adjust them manually with commands as needed.


By following these Klipper Pressure Advance tips, you will be able to unleash your printer’s full potential. Remember always to start low and go slow with the values while fine-tuning and using the proper measurement tools. You can also find online guides and videos to complement your learning process.

Additionally, always keep in mind that Klipper’s Pressure Advance is not a magic function; it needs some patience, effort, and experimentation to get the best results. However, the gains in print quality and speed are worth the investment in your time and effort.
