I have a large bread tin (900g?), and I have made a few loafs to fit the tin, however, it got me wondering what the max capacity would be for the TMX to handle. Though I guess it might depend a bit on the type of dough you are working with (I recently did a rye loaf which the machine struggled with a little).
I have done spelt loaf were I am using 700g of flour in total, and that seemed to go OK.
