Kart, it looks like you are having the exact same issue I am having with my new Form 2!!
The post is here: New Form 2 Print Problems
"I am a dentist and just got a new form 2 last week for dental model printing.
Right away I printed a few models in one shot using the grey resin I got and had great results.
Since the first or second print though, I have been having failed prints every time.
The cured resin appears to be sticking to the silicone layer at the bottom of the tank.
What I end up with is a builld platform with a base and a bunch of 2-3mm nub supports, nothing else.
Then, if I remove the tank, there is cured resin stuck the the silicone layer in a thin layer.
I have scraped that layer of the silicone, replenished the resin, let PreForm orient and do supports, changed support thickness and number, etc w no solution yet. Same issue every time.
The printer is literally a week old so I can’t see it being wear and tear, and everything is clean like new.
Please help!"
