Why Your Bambu Lab X1C Overhangs SUCK

I recently discovered that my Bambu Lab X1C overhangs SUCKED compared to my newer P1S and was really confused as to why 😫

Temperatures? Nozzle differences? Profile and speed differences? Literally none of these made any difference, regardless of what people suggested 😭

Then a hero on Reddit suggested it might be something that I hadn't even considered. Because I have an early Kickstarter unit, at some point Bambu Lab changed the cooling fans - and this was actually the culprit 🤯

By simply changing and upgrading the part cooling and auxiliary fan in our Bambulab X1C, we were able to get perfect overhangs just like our P1S for PLA 🔥

So if you experience bad overhangs and cooling on your X1C, you might just to change the fans 🙂
