@proclaim, last night I was printing “1950s_spaceship_v1_gcreate_logo.STL”, which is about 200mm tall, and I started getting many “Tilt detected errors”. In all cases there was nothing wrong, when I hit continue, it continued printing until the next error. I noticed the errors started at about 100mm high and where the x-y diameter was 100mm. I had about 10 stops until 80% done (where print body gets narrower) then continued without any error.
I did not notice any toolhead errors when printing smaller volume objects, even now.
I also have latest FS and FM v1.2.13.
