mesa hardware for mill retrofit

No it has no special limit switch.
Because has only 1 inverter only 1 or 2 spindle can work each time
this is selected by some switch in controller.
The question is if y axis spindle is enabled must change the axis orientation or must
be the same orientation with z axis spindle?
The mill is the same as the video with 5m/min rapids.
What is a good max following error value in a machine like this?

I think there are two ways to accomplish changing the orientation.

Easy way - have two LinuxCNC configurations.  One for vertical spindle, and another for horizontal spindle.  To switch between them, you shut down LCNC and restart the appropriate config.  Obviously this won't work if you want to switch in the middle of a program.

Harder way - use 'switchkins' component.  You define two different kinematic configurations and switch between them on the fly.  If you need to switch between spindles in the middle of a program, you need to do this.  Read the LCNC manual, under "Advanced" and the kinematics section.  I believe there are some example configurations with the switchkins module..
