I am not a programmer but it sounds like your programming is sound. If this machine has solid tapping as an option it should solid tap all day long. It sounds as if you have a problem with servo tunning. If the machine is set up correctly you should have no need for a floatying holder, this defeats the purpose of solid tapping.
I believe you have a problem with the machine not with the operation of it.

His programming could be sound but he had the wrong type of tap, a tap drill that was too small and inadequate lubrication; he is also working with a material that is sometimes difficult to tap as the properties vary even within the same length of stock and hard inclusions are not unknown in A36.
