I was taking very shallow cuts and noticed when the bit left the material it would slightly "spring" back into the non loaded position. It took almost 2 hours to remove 1/4" of material. As I mentioned before, this thing weighs 200 - 300 lbs and made of heavy aluminum so I thought it would be good for milling small stuff. Now I'm not so sure that I didn't waste my money on it and maybe spent a little more for something better. But my first mill was only $500, made of heavy PVC sheets and it cut wood and plastic accurate enough for some of the small stuff I was learning to make. Now I need to make some larger parts, which this one is 2' x 2' table which will allow me to make what I need.
