Several points. If you did the assembly, make triple sure that the nextruders were pressed into the carriers all the way. Very tough to pull them in with just the screw. I "gently" used a clamp to pull them together and then tightened the screw. Second, I would double check the belt tension using the Prusa tuner. Too loose or tight belts can cause random issues. After several weeks of use I readjusted the nozzle set screws and made sure they were sufficiently snug(but not too tight!). There's a bit of "feel" to get them tight enough but not damage the nozzle. Finally, every couple weeks I check belt tightness and rerun the nextruder alignment calibration. Good luck, its an awesome machine IMO.
For the smaller N64 cube, was the green the only color with the issue? It looked like the kind of surface you get when the tool is not properly secured to the carrier. If you have not greased the 3 hexagonal pins on each tool front face, do that. If that doesn't fix it, you may want to recalibrate the dock position of any tool that does that. And finally, if it's on ALL the colors/tools, then it may be a belt tension issue. Prusa KB has the audio tuning app thing, but also a test print that does extra non print moves to show whether or not the belt tension still needs adjustment.
Glad to hear you're knocking out some prints w/ the XL. Are you using the first XL w/the initial problems or second XL for those prints? To what % did you have to bump up the infill to get good prints in your examples?

Great to hear things are going better, I've been following along as I'm interested in buying a XL for multi material printing.
If you can build, Voron 2.4 ain’t that bad either
This is my dream printer. I wish Prusa had a sale or offer.

Love those Nintendo cubes!

Gears!
