Hi!

I've built my own printer which uses a DLP projector and a UV-LED light source which has fairly high light output. I can expose images with 300ms for Deep Black FunToDo resin to fully cure 100µm layers.
However, I'm always having these ugly stair-stepping effects on orthogonal surfaces related to the build plate. This looks more or less like this:

Left is how it should be, right is how it actually looks (red: light beams from projector, black: layers being produced, gray: build plate)

Any suggestions how to solve that issue? Are these signs of overcuring and/or light bleed? Might be pixel dimming a solution to that?

I'm having that effect on all FunToDo resins blends...

Thanks,
