I updated the firmware and now all my prints are having issues. Stringing, extrusion gaps, you name it. I even reran a print job that I ran before the update and it is now failing. I just want to rollback the firmware. I’ve learned my lesson about being an early adopter.

How do you get to the log file from the P1P? On your wiki I could only find how to access the X1 log file.

YES!!! THANK YOU!!! It worked!!! :partying_face: Finally! After installing the soft fever version of Bambu studio, doing the pressure advance calibration and changing my filament settings accordingly, my printer prints normally again! Thank you so much! :kissing_heart: [IMG_5260]

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 cl…

THANK YOU!. I’ve done this and updated my PA to .018 and it is printing fine now. Now to do this for the rest of my filaments.

Remember the P1P does NOT have lidar so you need to manually select the calibration of machine and the nozzle… under devise next to filament load and unload you see a button that says CALI… make sure the bed is clean and run the test this will allow you to set the nozzle for the best, once it prints…

Yes, same here, K-Faktor value was really strange value…

Hi, what will be the correct falue of the K Faktor?

Just do the calibration with Bambu Studio, this is best way to find out.

Is there a way to rollback the P1P firmware update?
