What is your K value? There is a bug with pressure advance, sometimes it enters a weird K value, it should be somewhere around 0.02.

Is there a way to rollback the P1P firmware update?

Thanks indirectly to this thread, I discovered my P1P was suffering from these issues due to this: [image] That was my pre-loaded/default value in Bambu Slicer. I had no idea what that random string of numbers was under “Ext Spool” until this morning and now I know it should have said something closer to “K 0.020”. No wonder my prints were failing so badly over the past couple of days!

how do I solve the problem, can you explain to me what I have to do and what are the steps?

First of all, make sure you have the latest Bambu Studio version 1.4.2.13.
In Bambu Studio, go to the “Device” tab. On the bottom right you will see your current filament.
Click on the little stylus icon on your filament and check the value in the “K” box.
