Ok, using generic Bambu ASA profile, engineering plate. Good bed adhesion. BUT, at 100mm height, spagetti started. Would this be fan and chamber temp issues? Suggestions, pls. THX!
Photos? 100 mm is already very high for an ASA part. Now maybe the X1E people can shine and explain why they want the one with the strong heating and an additional 15°C more in the housing 
Reactions from ASA also depend heavily on the filament supplier.
By the way, I break off the red marked part completely after printing and is only used to keep the shape. But it goes in the direction of “unavailable spare part”…
