I have recently purchased an Ender 5 Pro and managed to successfully print a large titan model I created with no problem. After this print, I had a bit of a break before getting back to it.
I don't know what has happened but now I just can't get my prints to print properly. I printed a large tower and it left holes in the top surface areas of my prints and my first layers print horribly. I have spent so many hours of every day, leveling the printer time and time again, I cleaned it up, checked for loose screws, etc. Still, to no avail, nothing has fixed the problem and still prints badly.
Maybe my print bed is warped and can't print properly. I am new to this so I don't really know.
I noticed my infill does not print particularly well in my prints and also has holes in the prints, as well as many overhangs, even if they a very small overhangs, become a stringy mess and need a lot of sanding.
The extruder gears are clean, I took some time to go over the whole printer and clean it up before trying again. I am using the Polyterra filament, it's still the same as when I last printed. My bed temperature is at 55 °C and nozzle is 200 °C, I have tried printing it with the nozzle at 195 °C and up to 210 °C with the same effect still occurring.
