“CNC-Ready” machines are not turn-key machines. And cannot be used until stepper motors have been installed
All machines that are described as “CNC-ready” have Stepper Motor Mounts, but do NOT include Stepper Motors, Linux computer & software, or CNC software.
The MASSO G3 CNC controller, power supply, stepper motors, cable system and optical encoder are sold as a part of our Accu-Pro line of machines and are not available for purchase separately or as an upgrade option to existing machines.
See our CNC Machining FAQs page for answers to the most common CNC questions.

We would like to share an encouraging development regarding the future of Sherline Products.
We are currently in discussions with an American manufacturer regarding the potential purchase of Sherline’s intellectual property and remaining inventory. The goal of this proposed acquisition is to preserve and revitalize the Sherline brand while providing continued availability of replacement parts, accessories, and machines for our valued customers.
As these discussions progress, we have agreed to temporarily suspend accepting new orders, effective October 19, 2026. This will allow us to preserve our remaining inventory while negotiations are underway.
Although no final agreement has been reached, we are hopeful that this opportunity will provide a positive path forward for the Sherline name and the customers who have trusted our products for more than five decades.
We sincerely appreciate your patience, understanding, and continued loyalty during this transition. We will share additional information as soon as it becomes available.
Our greatest hope is that the Sherline legacy of quality, precision, and American craftsmanship will continue for generations to come.

- Aux 4-axis control for additional drives/axes
- Relay card
- Three DB9 connectors:
- Limit switches
- External encoder*
- Aux tool setter or touch probe (one at a time)
- Three 2-wire Molex connectors:
- E-stop button
- Spindle control
- Laser
- Dual logic power: 5 VDC and 24 VDC
- Input power: 100–120 VAC or 208–240 VAC, 50/60 Hz
- 15 ft shielded Ethernet cable (controller to PC)
- External E-stop with 2 ft cord
- The controller connects directly to Sherline 24 V stepper motors via the Sherline 4-axis driver box (P/N 8760).
- Not compatible with MASSO 36 V closed-loop stepper motors.
- For DIY users with their own motors/drives, use the “Aux 4-axis” DB25 connector. Wiring information for DIY customers is available under the Specifications/Downloads.
- Program directly from hand sketches or prints
- Import DXF files and generate G-code without separate CAD/CAM
- Ideal for new CNC users and those unfamiliar with traditional G-code programming
- Buys CNC-ready Sherline machines and installs their own motors, drives, and encoders.
- Purchase the base Sherline/Acorn CNC Controller (P/N 9400) without options and wire to your own hardware.
- Upgrading an existing Sherline CNC system including older OEM systems such as Denford, D&M, LabVolt, Paxton-Patterson, or Light Machines. For a sample Denford/Sherline Microlathe conversion using Acorn, see: Centroid Denford/Sherline Microlathe Conversion
- If you already have a Sherline Linux PC or 4-axis driver box, configure the controller
with:
- Spindle Control Isolator Board
- External Encoder kit for your headstock (Standard or 3C)
- Wants a complete Sherline system: CNC-ready machine, 24 V stepper motors, 4-axis driver box, spindle control isolator board, and external encoder.
- The Sherline/Acorn Controller is designed to support all of these configurations.
- To control spindle speed via G-code, you must have a motor drive or the Spindle Control Isolator Board and an external encoder installed.
- These components work together to accurately acquire and control spindle RPM.
- If you do not include the Spindle Control Isolator Board at the time of purchase, adding it later will require returning the controller to Sherline for installation. Email orders@sherline.com for return instructions.

8″ Tabletop Lathe – CNC Ready
The Sherline 8″ CNC Lathe is a precision benchtop machine designed for small, detailed, and accurate turning applications. Built on Sherline’s proven lathe platform, this CNC-ready version includes factory-installed stepper motor mounts on both the X and Z axes – allowing you to add your own stepper motors and controller for complete CNC control.
With a 15″ long bed, 6″ crosslide, and a working diameter capacity of up to 3.5″ over the bed, this lathe provides the versatility needed for prototyping, small-part production, model engineering, R&D, and teaching environments. The rigid aluminum/steel construction, dovetail slides, and adjustable backlash compensation ensure repeatable accuracy on even the smallest parts.
All CNC-ready Sherline lathes include the same high-quality headstock, spindle, and bearings used in our manual models, giving you excellent spindle concentricity for demanding turning operations. The machine still allows for full manual operation when needed – simply turn the handwheels for quick setup or manual machining tasks.
