@Steve_Johnstone so what’s the word from FL on a replacement machine?
Couldn’t tell from those shots, was there any porosity as well as the flaking?
My machine seems to be behaving very well now with the choke in place; flaking is pretty much gone, and I run prints at one higher exposure setting to make sure I don’t get porosity. That is - I set preform to print in clear when I actually have grey in the vat, black for clear, and so on. See @JoshK’s list of resin exposure times here Resin list in order of exposure/curing?.
Not only do I have almost no flaking, but surface slime also seems much reduced and requires less IPA brush scrubbing to remove. I even suspect small holes are more accurate; I just reprinted my glasses arms and they slotted on first try, whereas previously I was having to carve out gummy surface resin from the fixture slots with a scalpel.
