Hi, is it true that white resin can’t be printed at 0.025 mm on the Form 2, but it can on the Form 1/1+? Is there a reason for this?

I believe that version 1 of the white resin supported 0.025, but the later ones didn’t. I’m not sure when version 2 was released, but it was a while ago now. I think it might have been before the Form 2 came out.
