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.
CNC Linear Controller – Z-Axis
This stand-alone controller is programmable from its keypad and controls the stepper motor’s function to which it is attached.
An 8-pin mini-DIN cable can be used to connect multiple units in a “daisy chain.” The units can signal each other to work in sequence, allowing multiple movements to be accomplished without using a computer or master CNC controller. They can also be used in conjunction with existing CNC controllers. The controller is user-programmable with two separate programs of up to 40 operations each. In each block, you can control distance, direction, speed, and whether the program pauses or proceeds to the next block.
The linear controller can also be “daisy-chained” with Sherline’s rotary controller to achieve rotary and linear movement combinations. This makes it easy to set up for relatively sophisticated operations like cutting gears without having to know anything about CNC programming beyond what is entered from these simple keypads.
Using a power feed offers several advantages:
- A constant feed rate gives a smoother, more consistent final finish
- The chance of errors due to miscounting handwheel revolutions is reduced
- No physical effort is needed for long cuts or returning the saddle to its starting position after a cut is complete
Programming is quick and simple, and programs are repeated at the touch of a button with high accuracy.
Items included with the CNC Linear Controller:
- Linear Controller w/Keypad

About the Controller Power Supply Current
The controller power supply is 110-240VAC compatible. It automatically switches from 110V to 240V for countries with 220-240 volt electrical current. The original power supply that we offered with this product was 110 VAC only.

12″ CNC-Ready Mill
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.
Standard Equipment for the 12″ Deluxe Tabletop Mill
- 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
