What is happening here?
I’ve been having some problems recently printing files which have previously printed fine. Both sets of prints have the same features, including a series of unintended grooves across the surface. The horses were printed as a set of three and consistently the third one simply hasn’t even started to print.
The printer is an Elegoo Mars Pro, using a new well shaken bottle of Elegoo ABS like resin, in a room at around 20 degrees. The files have been prepared using Citubox 1.8.1, the previously successful prints used an earlier version, on macOS BigSur 11.2.1
