I think that the heavy knee will always sit tight on the acme screw.
Other backlash may be at least repeatable. I will see. I am not
totally averse to just putting an encoder on the knee handle shaft.
Depending on how tight the ways are, it may be possible for the knee

What is the name of the rotary axis parallel to X? A?
What is the name of the rotary axis that is the spindle on a milling
machine? Or does a spindle not count as a rotary axis? All I want from

Igor,
All the names of axes are symbols used to facilitate conversation/use
between people and machines. The axes can be named anything you want. By
normal convention the A axis is the axis that the centerline of rotation is
parallel with the X axis. A revolves around X and B revolves around Y

My Bridgeport Series II Interact 2 CNC mill has a Z axis in the quill.

It has Z travel of only about 4.8 inches. Which is actually adequate
for most of what I do.
But, the other nice thing that it has is air assisted
Igor,
You have options with EMC2. You can use two different configuration files.
One configuration file to position the knee and use the quill as the Z axis
as Stephan suggests. Another configuration file to use the knee as the Z
axis and the quill as the W axis.
You can use the tool length

No, but there is the W axis, which is defined as a linear axis
parallel to Z. You could position W to get the right range, and still
use the quill for Z.
I think you could probably create a

So, my question is, does EMC2 support two Z axes and if so, what

It would be much better to make the knee the W axis (auxiliary linear
axis parallel
to the Z axis). EMC2 has facilities to handle an

Assuming your W is precisely normal to the XY plane of motion, you would get
interpolation of a straight line. All axes would accelerate
