Yeah, originally I had kept all the settings stock but I was having issues with bed adhesion and stringing when I swapped to a different PETG brand. I played with my extrusion rate until that other filament (Overture PETG) printed mostly okay… but honestly that filament still gave me issues on the first layer (mostly edge curling on the bed) so I just ate the extra cost and swapped back to Prusament.

I suppose it probably couldn’t hurt to try a print with all the stock settings just to rule things out.

Interesting - I’m using the stock values for feedrate (max 200 mm/s for XY; 12 for Z; 120 for E; no min feedrate specified), but those are probably tuned for the stock hotend and I can imagine they probably differ for the Revo.

The only thing I can find for the Revo that seems like it would give the numbers I need is this page which talks about max flow rate, but that’s different than feed rate (I’d imagine). The linked calculator puts my settings well within standard limits.

I can’t seem to find anything else online about it - is it just bringing the XYE values down via trial and error, or is there some formula I can use to calculate the correct feed rate?
