Gene, I use an X1 style machine for my show demo unit. One thing that helped an amazing amount at higher speeds was adding an outboard support to the lead screw. I cannot take credit for the idea, because frankly, I did not originally think it would help much. We have several guys in our local club with similar machines, and one offered/forced me to let him add them to my machine. It required making an extension to the lead screw, but the result was worthwhile. My guess is that the screw vibrates in the clearance in the nut and anchoring the outboard end significantly reduced the ability of the screw to move off axis as it vibrated. The task of extending the screws was made easier for us because there are longer screws available from Little Machine Shop for the large table option on the X1, and because we had the Y axis set up with the motor in the back of the machine, something not easily done on the X2.
