But if its not binding and cutting square is it still wearing? Everything wears, its part of the cost of using a machine. I doubt a hobby user would wear one out if its not binding, and if its does.... buy a new set of bearings after 20 years or so. Its amazing we have not heard these complaints over on the CNCRP area.

Bill, I question whether you can correlate cutting square with wear. You can always force the gantry square (to a limited degree with a welded gantry) when homing, but not so much as to cause obvious binding. So the machine may cut square, but still over stress the bearings and cause premature wear. How much wear is an open question.

I believe it is premature to expect to hear much about the topic on the CNCRP forum. It hasn't been that long since CNCRP switched over to linear rails on its pro machines. Time may show that it it works well, or they don't hold up. IMO, it's too soon to tell.
