    When I try to print occasionally i will get big globs of black burnt plastic I don't know what the cause is. It doesn't
    interfere with my prints but they come out really ugly.

    Sounds like burnt filament falling into the print.
    Check the hotend to make sure it is not leaking plastic from around the nozzle or the heatbreak.

    Sometimes if you are over-extruding some filament will be pushed aside by the hotend, that will cling to the side of the nozzle and burn a bit until it is snagged by another piece of melted plastic in your print, then get pushed in, it is usually in the infill area. Printing with black filament can hide all those burnt spots (JK).
