I’m working in a room with a lot of strip lights so I’ve just covered the top of the printer with a piece of cardboard incase this was affecting the sensors. I didn’t think it would make any difference but that seems to have fixed it. Please let me know if that works for you.
I was getting the same error with the White material at first.
To fix it, I had to push the right side of the tank in all the way but not the left. Kind leave it turned slightly counter-clockwise.
Their support page briefly mentions this and it seems to work.
Same error here. I have just installed the printer and this error appears before the first print… nothing helps. Very infuriating. Some response from Formlabs support?!
