The UC300ETH Plugin for Mach3 can read an encoder and be used for rigid tapping.? This not common and not well documented, but there is a macro for it.? The Mach4 Plugin cannot process the encoder to lathe threading or rigid tapping.? ?For Lathe threading, The ESS or the PoKeys would do a great job on Mach4.? Mach4 has awesome features for advanced lathe operations. It is worth looking at.
Note also that the latest UCCNC (1.2116) also supports lathe operations.? You may want to consider that.
Do not worry about encoder signal coupling, we have hardware on our website for this is you need.
