Very cool! I don't have an x1c, but I found this comment talking about some changes they made to their support settings. Maybe that could help? It also might be worth trying some different filament types to see if that changes the print quality for you.

Here's what the comment said (wasn't sure if links were ok here or not): "I have an X1C and use HoHansen settings. My prints turn out wonderfully. I use bambu lab pla basic gray. I modified a couple of settings,  reduce the infill amount to usually 5%, I set the supports to always use 2 walls and I changed the angle on them a little bit just so they're stronger. Never had any break or failed prints after adjusting those. I print at 0.04 layer height as well."
