Ender 3 with Sprite DD exturder, 0.6 CHT noz Manta M8P, klipper running on CB1 I have tried running the pressure advance from the klipper documentation here used cura with accelleration, jerk, and retraction disabled. I have watched the pressure advance change in the console so I know the calibrat…

Well, I’m a doofus, I totally missed that the nozzle size was set to 0.4 in the printer config. Changed it to 0.6 and everything is printing correctly.

Hello @analognmd ! Do you use both, the PA of Klipper and the slicer at the same time? Please attach the klippy.log to your next post. [image] analognmd: This is my first post, thanks for your help! Please do not delete the template.

With Cura I used the firmware pressure advance calibration command in the printers console. With Orca, I set the firmware advance to 0, and used the slicers PA incremental settings. Both cases I can see the PA go up in the console as the tower prints. I checked that my config doesnt have any PA set…

This is unrelated to PA. The nozzle size in Klipper is only used for certain sanity checks. Also see Move exceeds maximum extrusion (AA mm^2 vs BB mm^2) if you are interested in some background information.
