This stand-alone controller is fully programmable via its integrated keypad and directly controls the stepper motor to which it is connected. The stepper motor can be applied to any axis of a CNC-Ready Sherline machine.
An 8-pin mini-DIN cable allows multiple controllers to be connected in a “daisy-chain” configuration. Controllers can signal one another to operate in sequence, enabling complex, multi-axis movements without the need for a computer or master CNC controller. The system can also be used alongside existing CNC controllers. Each controller stores two independent programs, with up to 40 operations per program. For each operation, you can define travel distance, direction, feed rate, and whether the sequence pauses or proceeds to the next step.
The linear controller can also be daisy-chained with Sherline’s rotary controller, enabling coordinated rotary and linear motion. This allows users to easily perform advanced operations—such as gear cutting—without requiring CNC programming skills beyond simple keypad inputs.
Included with the CNC Linear Controller:
Linear controller with keypad
Power supply
#23 frame size stepper motor
Cables
Complete instructions
Note: To add CNC linear control to an axis on a Sherline machine that does not have a stepper motor mount, see P/N 8850.
Power Supply Compatibility:
The included power supply operates on 110–240 VAC and automatically adjusts for global use (220–240V). Earlier versions of this product shipped with a 110 VAC-only power supply.

The improper use of machine tools and their accessories can result in serious injury. Before using this tool, thoroughly read the instructions and make sure you understand its proper and safe use.
Always wear safety glasses when operating machine tools.
Our CNC-ready tabletop mill is ideal for customers seeking a compact CNC milling solution for producing small, precision parts. Made in the USA and backed by exceptional customer service, this mill offers full-size machine accuracy in a desktop footprint. Despite its size, it’s capable of cutting wood, plastic, aluminum, and even steel with impressive rigidity and precision.
CNC-ready mills come with factory-installed stepper motor mounts in place of handwheels and are ready for you to add your own stepper motors and CNC controls. Please note: these are not turn-key systems and cannot be operated until motors and controls are installed. CNC-ready machines do not include stepper motors, a computer, or CNC software.
Sherline recommends dual-shaft stepper motors so manual control is still possible using the included handwheels, which mount to the rear shaft once the motors are installed. Sherline also offers high-quality stepper motors and CNC components to complete your system.
Additionally, you can explore various aftermarket suppliers for compatible motors, drivers, and software. Visit our CNC Dealers page for a list of suppliers and links to their websites.
Note on Ordering a Metric Mill – Most Sherline cutting tool, such as center drills, are offered in fractional sizes. If you opt for a metric machine with metric collets or holders, you’ll need to order compatible fractional-size holders to use these tools effectively.
- A powerful 90V DC motor with electronic speed controller
- 12″ base with laser-engraved scales
- Brass leadscrew cover that keeps chips off the rear of the Y-axis leadscrew
- 2.75″ (70 mm) x 13.0″ (330 mm) table with laser-engraved scales and two T-slots
- 1.235″ headstock spacer block
- Resettable, zero-adjustable handwheels that can be mounted to the end of the stepper motors to maintain manual control when needed:
- (2) 2″ (51 mm) handwheels on X- and Y-axes
- (1) 2-1/2″ (63 mm) handwheel on Z-axis
- All with laser-engraved aluminum collars
- NOTE: CNC-ready machines cannot be operated manually unless double-shaft stepper motors are installed.
- ¼” Drill Chuck w/ key, #1 Morse arbor with drawbolt
- Pulleys, drive belt, three hexagonal keys, spindle bars, gib removal tool, eight-foot three-wire power cord, and instruction manual
- Oil reservoirs on the X/Y axes and the Z axis help keep critical parts lubricated. These were initially developed for CNC machines that run constantly for hours on end but can benefit manual machines as well
