Hey everyone.

I built an mk3s+ from its kit form successfully, tested a few PLA prints with the stock 0.4 nozzle.

I’ve set prusaslicer to use a 0.6 nozzle now that I’ve upgraded, and am using PETG. Prints look pretty bad, in spite of calibrating z-offset etc.

If you were doing something like this for the first time, what would your setup steps be like?

To be specific, using a diamondback 0.6 nozzle, matterhackers PETG at 235c.

Issues I’m seeing are a really bad loss of detail, lots of stringing, etc.

eta: added a photo of a moderately post-processed part. Notice how rough the top surface looks, there’s a disconnect between perimeter loops, etc.

    You basically have to retune your profiles to match between the petg and the larger nozzle.

    Oh yeah, and you’re going to lose detail with the larger nozzle compared to a 0.4 but it’s a trade-off

      I know what you mean re: some detail loss, I’m talking about perimeter lines that just outright look like they were gouged out with an ice pick. It’s really bad.

        Saw the pics and it honestly looks like over extrusion, especially that top surface
