This is the interface PC board for the Clough42 Lathe Electronic Leadscrew controller. The goal of the project is to replace the change gears or gearbox on a metalworking lathe with a stepper motor controlled electronically based on an encoder on the lathe spindle. The electronic controller allows setting different virtual gear ratios for feeds and threading.
This PC board mounts on a Texas Instruments LaunchXL F280049C prototyping board and provides connections for power, an encoder, a display and keypad and a stepper or servo driver to drive the lathe’s leadscrew. For more information on this project, search “Clough42 Electronic Leadscrew” on YouTube, or “clough42/electronic-leadscrew” on GitHub.
Included in this package:
- ELS Boost v2.1 PC board assembly
- Power connector
- Two (2) 2×10 female header connectors
- Two (2) 5-pin right-angle headers
- One (1) 6-pin servo connector
- One (1) 6-pin servo screw terminal plug
Through-hole soldering is required to attach the provided connectors to the PC board. Important: solder the power connector first; it’s hard to do after the servo connector is added.
To complete the project, you will also need a LaunchXL prototyping board, display, encoder, servo or stepper with driver, and other hardware. None of this additional hardware is included. See the documentation on GitHub and the YouTube videos for more information.
