I have bought an Ender 5 3d printer, it prints fantastic for a long moment, but now, everytime I print, the prints failed and don't look good anymore.
I have tried so much things to bring the old quality back. things I have tried are: new nozzle, new software, extruder calibration, cleaning hotend, new leveling. the settings in Cura are mostly the same as before.
Please can anyone help me, I'm struggling with this for 2 weeks now and I don't know how to solve it.
I bought the printer in september
