Fast microscope printing? Prusa i3 Mk4 with input shaping

I have tried PETG, it prints fine but I have not tested it extensively yet. I have one PLA and one PETG that are destined for testing in an incubator, but they have not made it there yet. In handling, the PET looks and feels more supple but there are some instances where it seems to have been more brittle and I have cracked parts.
