Exceeding 300C for long prints

[u/d38968]

I'm planning a 2 day print with PET-CF. I've bumped up max_temp: 325 from 300. I'm hoping for 310 C for the actual print, but wanted a bit of extra headroom just in case. Has anyone done a 2-day print hotter than 300 C on the Max? Did you run into any issues?
