Hi All,
Quick question - any thoughts on what may have caused this? It was printed on an X1C at normal speed wit Elegoo PLA and a MicroSwiss .4. It isn’t a catastrophe; I’m just curious about what others think.
Guesses in order of likelyhood:
A) Moisture in the filament
B) Flow Dynamics calibration off, Lidar lens dirty? The self-test lidar calibration will tell you about Lidar issues.
C) Cold chamber (aim for 30-35°C)
D) Fan settings not good or cold air drafts coning in
& 
Thanks for the input. Flow dynamics was off but you may have hit it on the head about a draft - the printer is new and I set it up in another room temporarily, with the AC blasting.
