Prusa Slicer needs more functions for resin printers
PrusaSlicer is very basic for resin printers, for experienced users it is manageable but for new users it can cause many printing errors until you understand what each part needs to be printed.
Since the SL1S is an expensive printer, it should have a more robust Slicer. Functions that Chitubox does have.
To check if the number of supports is sufficient, in PrusaSlicer the "code" must be generated for each modification. In Chitubox you can simulate the supports in real time.
PrusaSlicer does not have the black guide line for each layer
A new user would use automatic supports generation but that feature never generates enough or in the right position, you always have to generate manually to ensure each print.
I think they could follow the example of programs like Chitubox or Preform. Due to the time that has passed, it was expected that these types of functions already have the new version 2.7.2, but it still has the basic functions of a resin program.
