The ball screw benchtop lathe is a reimagined version of our popular 17″, 4400-series lathe. The lathe has a new solid aluminum base, which creates a very rigid assembly, a beefed-up saddle to accommodate the ball screws, and a larger 8″ crosslide. Please note that our ball screws only come in a metric pitch.
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.
- Centroid Acorn CNC control board

- Internal wiring to DB9, DB25, and 2-wire Molex connectors
- Power supply, push-to-reset circuit breaker, and cooling fan
- External Ethernet port, power switch, and power LED
- Ethernet connection
- Power switch and power LED
- Cooling fan
- Three DB25 connectors:
- Sherline 4-axis driver box
- 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.

Sherline/Acorn CNC Controller
The Sherline/Acorn CNC Controller is a fully integrated, plug-and-play control designed
for Sherline CNC machines and compatible third-party systems. It combines the industrial
Centroid Acorn CNC control with a custom Sherline housing, wiring, and connectors to
simplify installation, upgrades, and retrofits.
Centroid CNC, founded in 1979 in Howard, PA, produces high-performance, industrial-quality
CNC controls. The Acorn controller is an excellent upgrade for both new and older Sherline
CNC machines, including legacy systems originally supplied to OEMs such as Denford, D&M,
LabVolt, Paxton-Patterson, and Light Machines (Spectralight).
