Title: Stepperhead CNC Lathe Cutting Threads
Post by: jackary on February 17, 2026, 01:15:57 PM
Rather an old reserection to this thread, but here is my attempt at making a CNC/manual lathe that can cut any thread pitch etc using Turbo CNC on an old laptop converted to run on DOS. It is rather a long description of the machine, but at the end of it it describes cutting a thread. That is if you can get that far before losing the will to live.

Thanks Alan -- very nice. I've long admired your Stepperhead lathe. It is a full CNC machine running on CNC software, not an electronic change gear project, so it seemed more appropriate to show a video of its screwcutting capability here.

If it's using TurboCNC, I'm guessing it uses a hall effect sensor for feedback while screwcutting, rather than an encoder, but I could be wrong.

Did you ever build Stepperhead 2?
