Real buildvolume for PA12?

Completely useless to have a machine that claims 165x165x300 buildvolume when you cannot use it,
even more useless to have Design guidelines and adhere to them and still not being able to work…



Even going lower at 157.95 mm on Y axis it doesn’t fit

But if you organize with the preform tool you get 158.49mm on Y and it fits…
Y dimensions are greater than the previous one…
