I am a new user to Chitubox and have been working through a lot of the issues I have come across, but this one is escaping me. I am trying to print some T-Rex ribs on my Mars printer. Each of the ribs has a sequence number on the bottom that is against the build plate. When I slice the model and look at the layers, layers 1-20 clearly show the sequecne numbers. The printed ribs look great, but they are shiny and smooth on the bottom without even a hint of numbers. I tried sanding one down to see if they where there at all, and they are not. How do I get the sequence numbers to print?
