Meanwhile, the nixie node address flickers at intervals of 1S (0.5S on and 0.5S off) for 5S.

And in the initialization stage and the normal operation stage, if the node address is changed, the nixie tube carries out flickering (0.5S is on and 0.5S is off) display at the interval of 1S, and the nixie tube continues to return to the original display state after 5S.

The status of each axis in case of failure shows:

in the nixie tube display information, 1-E, 2-E would be used to distinguish between the shaft 1 and shaft 2 stepper motors, respectively.

The display logic is as follows:

and in the normal operation stage, if a fault occurs, the combination of the nixie tube and the shaft indicator lamp flickers to display a corresponding alarm code.

If only one axis gives an alarm, the indicator lamp of the corresponding axis is lightened, and meanwhile, the nixie tube flickers to display a fault code.

If both axes alarm, the two axes are the nixie tubes and alternately switch to flash at intervals of 1 s.

After one axis fault is solved, the state display is switched to a scene of one axis alarm display; if the failure of both axes is resolved, the state machine display switches to a real-time state display.
