On those of you who print slow: Did you “upgrade” your module for better print cooling? E.g. by adding an external fan or using the new printing module? For those filaments that can be cooled without negative side effects (e.g. PLA) this allows for much higher printing speeds and usually even gives better results. The original printing module was very bad at print cooling if unmodified. For reference: I typically print at 60 mm/s on the SM2 (with added fan) and have no issues, and on my old CoreXY-printer I ventured up to 120 mm/s, which however caused some ringing visible in the print, so more typically I’d run 100 mm/s.
Especially with the huge build volume of A350 faster printing speeds are desirable…
