That's (a4988) a stepper driver, what software are you using? The problem with threaded rod is it is not designed for linear motion at all.
I don't think you can get any accurate / repeatable...

What are you using to control movement?
I would recommend a CNC4PC spindle speed controller board, some specifics (what is your motor control board xmt or xxx etc/) are in order. I'm working on a similar mod.

I really like it (the Dewalt) as my spindle it's - more powerful, quieter, easy to mod for use with the SuperPID and I also got precision collets (www.precisebits.com) for it.
It works great. ...
I built a momus 2.1 last year (2015) in about 5 months. It's 42" x 36", dual motor x-axis on based Mac's Momus X2S ' modifications.
