We need clarification on what you mean by threading: a parallel computer process, creating threads on a screw on a turning center, or threading a hole using a tap controlled by a CNC machine. If it's the latter two, you would rely on the stepping motors and dead reckoning (open loop system). Stepping motors will move exactly as instructed and have exact stop and positional accuracy so the threads would be constructed as intended; therefore, no need for encoders and feedback (closed loop system)
Additional Information:
What he is asking perhaps is that how would he be able to do rigid tapping without encoder input? Alternatively, he may need a servo drive for the spindle. Which board supports rotary encoder input? I am looking for boards myself.

Planet-CNC breakout board supports encoder inputs. I don't see this feature on your's. How does your board support threding, etc.?
