The CNC saw beveler is a two axis machine, X and Z. It's stepper based, with two steppers on the X axis, one slaved to the other. I'm at work and don't have access to the computer that runs the machine. I have manually "probed" the X axis and have a listing of all the heights per inch of the X axis (no way to really use a machine probe under probekins due to the nature of beast). But mapping out Z axis height for a given X position is definitely what I'm interested in doing.
