I just ordered a Super-PID feedback control unit for my router. For those who have this on their router, Do you see a difference in smoothness of cut? I am installing it first on a router table and a Woodrat. Then on a CNC unit that I will build. The theory is that since the bit speed will remain nearly constant, the cut will be smoother regardless of the density changes in the wood. Of course, the feed rate into the bit will have to be nearly constant as well. They have not yet acknowledged my order, and I'm wondering if I jumped the gun on this purchase.
