I think all is well, the spreading just seems to require that the
roller goes at about the same speed as the gantry so it effectively
acts like a non rotating roller that prevents digging in of the
material it pushes.

Ted who has access to a zcorp machine seems to think that the roller
is just powered by an open loop dc motor, this seems reasonable but
for development I want to use a stepper, that way I can try different
gantry speeds as well.

Of course if there is a wall the more the merrier when it comes to
climbing it.
