I'm just getting into resin printing with a Mars 2 pro mono.  I have downloaded and installed the free version of Chitubox.  I have my first model ready to print.  When I go to settings and try to select the machine type, I select Elegoo but I get AnyCubic Photon in the list. No matter what machine I click on it always gives me the AnyCubic Photon.  So a saved slice file has the wrong file extension for the Elegoo printer.  What am I doing wrong??
