Printing problems with p1p

[selprint3d]

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!
