if the machine moves in .002" steps or even better with the new gears why isnt the accuracy better than the stated .005-.015"? are some cuts right on size and some off? would some one please plot with a fine point pen (this way there is no load) a one foot sqaure and measure it with a good metal ruler to see how close it is perfect? lets put this topic to rest once and for all with a difinitive answer. thanks guys, this forum has really helped me in the leaning towards a shopbot!
