This is a simulation of an XYZBCWY 5 axis bridge mill.

Example demo:

 1) $ linuxcnc 5axis.ini
 2) F1 ---------- Estop off
    F2 ---------- Machine on
    CTRL-HOME --- home all
    F5 ---------- MDI tab
 3) orient vismach gui as required
 4) g0w10   ; retract w
 5) g43h100 ; tool offset (100)
 6) g0b45   ; tilt 45 deg wrt z
 7) g0c30   ; rotate 30 deg in xy
 8) g0w-10  ; simulate drill
 9) g0w10   ; retract drill
10) etc

Note: Motion for the W coordinate is incorporated
into the motions of the joints used for X,Y,Z
motion but a corresponding joint.5 is needed to
correctly display W values.

The joint.5.motor-pos-cmd should be looped to the
joint.5.motor-pos-fb and joint.5 should use immediate
homimg (HOME_SEARCH_VEL = 0).

The 5axis.ini illustrates how to use multiple (2)
joints for the axis y coordinate.
