While printing I was getting random rectangular chunks of exposed resin on the build plate or the vat (or sometimes embedded half way in a print) or parts that simply fell off as the layers were randomly shifting.
Was kind of intermittent so dry running the printer and timelapsing was the only way to catch it misbehaving.
I believe this was caused by electrical interference from either dirt between the solder joints or the proximity of the ribbon cable to the mainboard - it was stuck down pretty tight with tape and was in direct contact with solder joints on the bottom.
Resolved by removing ribbon cable from LCD to mainboard. Cleaning mainboard and LCD connector thoroughly with isopropyl and a clean soft brush - removed adhesive residue (with lighter fluid) from the tape that was holding the ribbon cable to the mainboard. Insulated the black rear side of the ribbon cable with electrical tape as there's no easy way to route the cable without it touching something on the board.
I'm pretty confident dismantling, cleaning and reassembling electronics but I wouldn't recommend this an easy user fix.
