I want to use an SD card for my printer in case Windows decides to self-update, despite me setting it to not do this automatically, and I don't want to fail in the middle of my print. Hosting the GCODE can also cause issues if your computer lags a bit. The printer will sit, with a hot nozzle dripping plastic below, until the next command arrives. This shouldn't typically be a problem, but sometimes systems can lag hard, and who wants a needless blob of filament on the surface of their print?
