I have a Form 1+ and just got my Form 2. I am doing my first print right now.
As I was sitting there watching everything for the first print, i.e., heating, filling tray, etc. I noticed my wiper, while installed, was not square to the tray and it looked like the print head would hit it when it lowered as it was angled in slightly at the back.
I opened the cover slightly and made sure and pulled it forward slightly to completely seat it on it track. This straightened it out but I could have had a disaster.
It might be worth a warning in the preform software, i.e., is your take filled, is your wiper straight…etc.
