Threading on a CNC lathe requires a spindle encoder so the tool makes consistent pitch passes. A rotary encoder is added to a South Bend SB1001 lathe DIY CNC and attached to a Mesa 7i76e board. LinuxCNC drives the lathe to perform the threading operations. While concept is sound, a new pulley is needed to make the project perfect, but the parts will not arrive for a couple of weeks.
If researching for your own project, make life easier and start with a 1:1 pulley ratio between the spindle and rotary encoder. Glad to answer related questions in the comments.
