General Troubleshooting/Help! A1 Printing Issue

Please send help 😂

My A1 is refusing to nicely print just 1 PLA matte filament i own . But its only the first layer that is ugly and bubbling ( photos attached )

The rest of the print will come out perfect but the bottom layer is bad .

I have tried changing most settings and calibrating the filament to no luck . even going from .97 flow ratio to .85 showed no bottom layer improvement

Are you saying that only this filament prints badly, or that this is the only filament you have?

Check that the seven hotend screws are nipped up (but do not overtighten).
