I am near completion of a 6x12 router using a KFLOP and snap amps,
this machine has dual AC servos on X,and AC servo on Y, 3 independant Z axis with steppers.
it has taken a lot of input from Tom...

I used an air cylinder on my x axis and I just dialed up the pressure until I had the right preload. This was a lot simpler than Jack's method".
What a great fix!, also makes mounting a breeze!...

Is there a...
