Hello, is this a 3d printer Anonymous? I have prusa i3 mk3 upgraded to mk3s. This is my second printer, and I don't have much trouble with it, or need to upgrade. It boringly works

Before that I had cr-10, it was moderately modded (replaced hotend, fans, glass surface, stepper motor dumpers, and small tweaks here and there). I was never able to get any good print from it, but learned a lot. Two problems were the most common: adhesion (surface was very uneven, even after replacing the mirror), and random extrusion problem after a few hours of printing. It was beyond my skills to make it working, that's why I have prusa.
