Welcome to the forum! If you give us some more details as to your print settings, hopefully we will be able to help.
Are you using default Luban settings or custom settings? What material and temperature are you printing at? A screenshot of your sliced G-code could also prove useful in diagnosing your print quality issues.
From the limited information I would say it could be down to printing too quickly, poor filament quality, loose bed/carriage or possibly extrusion issues.
If possible try to film your printer for 30-60 seconds whilst printing as this may also help us diagnose.
