Now I am getting a code that says low DC bus. I sense a new thread coming if I can't sort it easily.
    You find things out which are peripheral to the problem - code Lv on the VFD display only means Low DC bus and this is OK when the power is running down.

    But I have diagnosed the problem - I reassembled with the microswitch that is for the headstock gear train safety cover swapped with the chuck guard switch (one is NC and the other NO). So my next session in the workshop will fix that and the covers will go back on. Job done ! No need for a new thread
