no, 'motion' is not the key, its the fact you are clearing the copper surface
from the byproduct produced by the chemical reaction. of course I am not
referring to the (microscopic) physical phenomenon of the debris leaving the
surface like ion movement, I mean shaking (or whatever) the board, the fluid,
the container, etc.
your blender may be not at all better than other methods if it fails to clear
the copper surface of the non etchant product.
HOW you clean (continuosly) the copper surface and let the etchant get to it is
YOUR METHOD, and there are lots of them. mine is to wipe and have fun watching
the copper disappear. if I had better things to enjoy, I would not be etching
anyway. if I had to mass produce boards I would go with spray and/or some
mechanical wiper.
