White turning grey?

Hi folks.

In between the Motor Error messages I’m getting a couple of prints done, Woohoo!

I’ve just noticed the last thing printed using the standard FL white looks decidedly grubby, in fact it’s almost grey. What’s really odd is, it’s very grey on one side and not the other.

I’ve never noticed this before, the resin printed a couple of things perfectly just a few days ago, I keep everything clean.

This object is going to be painted, so it’s not critical, but something ain’t right!

Any ideas what’s going on?

Did you shake the cartridge before printing?
