we just got a batch of version 4 black resin and the prints turned out to be very soft, nearly as soft as the flexible resin.
With version 2 black resin printed hours before we didn`t had this problem.
Preform and printer softw<are/firmware are up to date.
Did anyone else experience similar problems?
Same issue here. V4 Black resin. Printed a lot of pieces, and it seems that only small ones stay soft, and when part is big enough there are good chances it will be hard (but not always).
