Basically I am getting voids in what should be solid prints. Thin outer edges of the print are printed but sections of the interior that should be solid are completely empty, leading to a failed print. This seems to occur sporadiacally and it doesn’t depend on the geometry of the print file because sometimes the same files will print successfully. I’m not sure if it tends to occur more in a particular part of the build volume.

I have been using clear resin V4. I don’t know if the issue occurs with other resins, I haven’t tried. I haven’t tried all the standard troubleshooting steps yet, so apologies if this post is considered to be premature - I just wanted to check if others (besides @armstrongc93 ) have noticed this issue and know of the cause.
I have filtered the resin, checked the clarity of the bottom of the tank (LT) and checked for any obvious debris or smudges on the optical window. I have also updated to the latest version of preform.
Does anyone have ideas about what might be causing this?
