Pressure advance compensates for the spring-like behavior of filament under extrusion force, and must be tuned per material and printer. While Bambu Lab uses a Lidar scanner for this, other printers like Prusa and Snapmaker U1 only have load cells available. Stefan measured how different extrusion rates affect load cell readings and built an open-source calibration tool for Prusa printers working with stock firmware. Related open-source projects like Auto PA Calibration are also mentioned. ## Full article daily.dev links to this article rather than hosting it.
