I have a MK3S and a MK3S+, one with a stock nozzle and one with a Revo. I print the same gcode on both machines and haven’t seen a need to tweak the settings for the Revo. Have you tried slicing with the default settings for Prusament PETG in Prusaslicer?

I switched to Printed Solid Jessie filaments after my previous bread and butter supplier, 3D Solutech, went out of business. Jessie is been good so far for a relatively low price. I hope they continue to expand their color lineup because they’re still missing a lot of shades I used previously. I’m still searching for a secondary brand to fill those gaps.
