Lathemaster 9x30 CNC Conversion

Last modified: April 16, 2024

I've been plotting and planning a CNC conversion for my 9×30 lathe for some time now. This page chronicles the journey as well as the ultimate destination.

Various electronic components and parts, including wires, circuit boards, and hardware.

Collecting Parts...

Various metalworking machines and tools.

Project Introduction: What do I hope to accomplish and how am I planning to get there? This is a brief history of how I got into this mess in the first place. Also discusses the E-Leadscrew idea.

An old computer monitor on a metal box in front of a window, circa 1980s-90s.

Driver Enclosure and Swingarm Rack: 19" Rack Enclosures for PC and Driver Electronics and a swingarm for the LCD touch panel, keyboard, and lathe control panel.

Red electrical component with silver top and cylindrical protrusion on black cord.

Step Motors and Mounting: Basic direct drive mounts for NEMA 23 step motors.

Silver micrometer with black handle and curved jaw on light gray background.

Machine Tool Accuracy: Results of my research on factors governing accuracy for CNC conversions.

Red gear with teeth against dark background.

Optical Limit Switches: Wherein I design and build my own limit switches based on a slotted optical switch.

Control panel with red button, metal knob, and colored buttons on a light-colored background.

Control Panel: A design for a lathe panel that maximizes opportunity for manual as well as CNC control.

Colored blocks stacked vertically with connecting line and cylindrical base, each with black text inside.

Software: Much is driven by the choice of software!

Red gear with teeth against dark background.

Gang milling cutter, 3D model.

Ballscrews & Gang Slide: Once the basic lathe is up and running, the next step will be some upgrades like these!
