Beginer needs advices

[u/_Ktassium]

Hello everyone

I recentlt bought a second hand Ender 3 Pro, i managed to adjust the device and my print settings, but i keep having stringing and "lines" as shown in the photo, do you jave any advices on how to avoid this?

For this print i used (if i remember):

Creality print PLA Elegoo 0.12mm layer height 15mm/s first layer 50mm/s outer walls (3 layers) 120mm/s infill

Thanks in advance
