100 bed is pretty reasonable. 260/270 seems pretty toasty, but if it works it works.
Do you have a bedslinger, CoreXY, or something else? Bedfans made a world of difference for chamber heating rate. There are a number of bedfan and active carbon combinations that I’ve found to be fairly effective at chamber heating and reducing odors.
Are you recently enclosed? If yes, beware that everything will expand enough to throw off your first layer if you don’t accommodate for it.
I’ve only run ASA so far, but even sticking with the same brand I’ve noticed that different colors have very different temperature and extrusion multiplier needs. Prior to ASA I stuck with PETG and I used the same settings for any color but white.
