For a direct drive stepper you need between 2-5 tpi on the feed screw. AND always keep this in mind That screw will be in the NASTIEST, abrasive place you can ever place a screw in period, bar none. Either count on replacing it often or use bellows to protect the screw and nut.
Play on the screw will drive your THC nuts and give terrible cuts.
You only need about 6" of travel max.
