Comment on Persistent Curling

I had these types of issues a lot before I built an enclosure for my printer. It’s like night and day difference being able to keep the ambient temperature consistent throughout the print. A brim can also help with this but the enclosure is the real answer.
My mk4s is in an official prusa enclosure and I still get warp on large parts. Depending on the part I will take one or more of these additional measures, they all help:
is there air moving around in the build chamber? I suggested an enclosure above, before seeing this comment. argh, that really should fix it…
I do have a circulation fan but I only turn it on for materials that want more cooling like PLA. For higher temp materials (mainly PETG but I also print some ASA, PA, PC, TPU) I keep it off. Which is a little frustrating because I got it originally to circulate air through a carbon filter for fumes from those nastier materials.
Plus no dust, so when you get the machine dialed in, it just stays that way
