First layer print Failed

[user_2471490819]

Filament used for test : ABS et PLA
Plate : Textured PEI Plate - cleaned well and when printing applied glue for adhesion.
Setting : Basic Bambu lab setting except I changed outer wall speed to 100mm/s

Enjoyed the past 6 months with out any problems with my Bambu Lab P1S. The past two days I couldn’t even print a single one. Print failling from the first layer. I thought its a clog problem, so I did Hot end Clean up (I even changed a new hotend) and checked if Filament stucked on the Extruder gear. But both looks fine and my print still failling from the 1st Layer. (see Images below)
I will appreciate with you support if you have a solution. Thank you all.

A factory reset has solved this issue for others on the forum. It seems like an incorrect flow dynamic value is causing the issue.

It seems to be a problem when the extruder head changes directions. It stops laying down filament, but then gobs it back up on the…

Terrible first experience with the P1S and AMS 2 Pro, help welcome

Hi, I have setup a brand new P1S with ans AMS 2 Pro and so far it has only been a nightmare. I pulled the trigger on this because of all the positive comments on Internet about “it just works” but so far I am truly disappointed. I have been 3d printing for several years so not a total newb. For the moment I have removed the AMS 2 since it does not work. i.e. it is not even able to push filament to the buffer (does not matter which position in the AMS) and this is basic PLA that comes with the …

It works well the factory reset. Thank you JohRaymond and ramcdona for this great tips. Now back to printing after struggling for two days.
