No noise issues.
All of the stepper motors are located in the rear of the machine.
All of the...
If you ask about the CAM program to use the 4th axis in ordinary cases. also in Vcarve pro when you save the tool path choose the post processor as in the attached photo.
Note that:
If your rotary axis is parallel to Y axis you will modify the last method as follows:
Replace (G17) by (G19)
Replace (X) by (Z)
Replace (I) by (K)
I use my own new technique to operate the stepper motor of the 4th axis in one direction simultaneously with the other two axis (Z & X) or (Z & Y) instead of rotating the 4th axis motor left and...

1st trials.
spiral column - 3 door - 1.5" diameter - 17" length - 3" pitch
Square column - 4"x4"
Z axis movement, please note the vertical movement of the mechanism block to compensate the axial displacement of the wire along the threaded axis.
