I'm drawing up the PM-833 X plate for the motor side. I want to place the coupler under the table this time. This makes the system shorter but also the two main hold down bolts interfere with my standard N34 plates and the end support bearing. So I'm looking for the center location of the stock lead screw in relation to the underside of the table and the top side of the Y slide.

This will make the X axes about 1.5" shorter and it would be nice to fit a D=40mm coupler. Its going to be tight for the 40mm but it will last longer.

Thanks guys.
