Abstract: We establish an effective equidistribution theorem on homogeneous spaces for expanding translates of product-type self-affine measures seen on unipotent orbits along any sequence of diagonal elements drifting away from walls. In particular, we do not require the diagonal elements to lie in a fixed proper and closed subcone. The main new ingredients in the proof of our equidistribution theorem include an adaptation of the methods in \cite{BHZ25} to the setting of product-type self-affine measures, as well as a weighted effective recurrence theorem for intertwined associated random walks. The latter involves decomposing the random walks according to suitable stopping times and applications of intertwined Benoist-Quint height functions.
