Hello people,

I’m quite new to 3d printing, did some 3d printing before and just bought an own 3d printer (creality CR-10) started with some first prints with basic settings and they were great! but after doing some other slightly smaller and bigger prints the quality of the prints is going backwards (with the same model) (as shown on the picture, the white one is one of my first prints in great quality and the black ones are the latest ones) you could say that I changed the filament but that weird stringing started also with the white filament. And yes I tried some different settings such as: higher/lower bed/nozzle temperature, enable/disable retraction, higher and lower print/fan speeds and higher and lower print flow. I also tried releveling the bed and cleaning the nozzle. I have to say the nozzle has a slight leak when at the right temperature but that was also when I printed the first one and that hasn’t affected the first one… So I don’t know what I have to do/clean/tweak now to make it better… And I’m sure you guys have the solution.

Oh and by the way, I have an another problem too now, because the nozzle temperature drops randomly so it is not melting the filament, until the temp rizes and then it starts to print again and then it is one messy bunch of plastic…
