This stand-alone controller features an integrated keypad for easy programming and controls the operation of the connected stepper motor—no external computer or CNC system is required.
An 8-pin mini-DIN cable allows multiple controllers to be connected in a daisy-chain configuration. Each unit can send and receive signals to operate in sequence, enabling multi-axis motion without a master CNC controller. The controllers can also interface with existing CNC systems for more complex setups.
Each controller supports two independent programs, with up to 40 steps per program. Each step can define travel distance, direction, speed, and whether to pause or automatically continue to the next command.
The linear controller can also be daisy-chained with Sherline’s rotary controller, enabling combined linear and rotary motion. This simplifies more advanced tasks—such as gear cutting—without requiring any G-code knowledge beyond the simple keypad inputs.
Included with the Linear Controller:
Linear Controller with Keypad
Power Supply
Power Supply Specifications:
The included power supply is compatible with 110–240 VAC and automatically adjusts to local voltage, making it suitable for use worldwide. (Earlier versions of this product included 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.
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.

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.
Sherline has advanced its precision 4" rotary table into the 21st century with the addition of Computer Numerical Control (CNC). This upgrade makes it an ideal solution for clockmakers, gear cutters, and anyone needing to machine intricate radially symmetrical patterns. The CNC rotary table takes the complexity out of repetitive indexing tasks.
Complete, Stand-Alone System
Programming is done entirely through the integrated numeric keypad—no computer required. The system includes everything needed for operation:
4" Sherline rotary table with pre-installed stepper motor
Microprocessor unit with numeric keypad
115 VAC power supply (universal 110–240 VAC compatible)
All required connecting cables
Mounting Options
The rotary table includes clamps and T-nuts for mounting to the T-slots of a Sherline mill table. Additional options allow for flexible positioning:
Right-Angle Attachment: Holds the table vertically at a 2.7" center height. A matching right-angle tailstock is also available for supporting long workpieces.
Tilting Angle Table: Allows mounting at any angle from 0° to 90°. At 90°, the center height remains 2.7", compatible with the right-angle tailstock.
Simple, Accurate Operation
Simply enter the steps per revolution (or degrees per step) via the keypad. The table advances precisely to the next position at the press of a button. If needed, previous positions can be recalled instantly.
Resolution: 28,800 steps per revolution
Accuracy: ±0.006° per step
This precision allows for accurate machining of gears with odd numbers of teeth, and built-in calculations prevent cumulative errors.
Flexible Integration
This CNC rotary indexer is a complete, stand-alone unit—perfect for complex indexing operations. It can also integrate with other CNC systems:
Accepts input signals from an external CNC controller
Sends “completion” signals back to the master controller
Can be daisy-chained with other units for coordinated actions
For more advanced applications, the rotary table can be linked with Sherline’s linear controller (P/N 8800), enabling seamless combinations of rotary and linear motion—ideal for gear cutting and other multi-axis operations, all without requiring advanced CNC programming knowledge.
Weight Capacity (Continuous Use)
Horizontal orientation: 50 lbs
Vertical orientation: 30 lbs
Vertical rotational torque: 6 ft-lbs (e.g., able to lift a 6 lb. weight 12" from the center)
Note: The table can handle heavier loads if not under continuous use. Refer to the Video tab for practical examples.
Power Supply
The controller power supply operates on 110–240 VAC and automatically adjusts for global use. (Earlier models included a 110 VAC-only power supply.)
Compatibility with Tilting Angle Table (TAT) Limit Switches
For instructions on using the rotary table with limit switches on the TAT, see the “Instructions” tab and download the PDF titled MASSO Rotary Table Limit Switch Interference on the Tilting Angle Table.
Sherline stepper motors feature shafts at both ends, allowing for manual control via a handwheel, if desired. Flats are ground onto each shaft to accommodate set screws for the handwheel and coupling. For use with a Sherline motor mount, ensure that the shaft entering the coupling has a flat machined or ground onto it where the set screw secures it. Failure to do so may damage the shaft, making the coupling difficult to remove. For non-Sherline applications, the flat may not be necessary.
P/N 67127: This motor comes pre-wired with six leads in a connector that plugs directly into Sherline's linear or rotary controllers. Both our CNC system and driver box include four pre-wired cables with 5-pin plugs that match the P/N 67127 stepper motor. Simply plug each stepper motor into the corresponding axis cable for an easy setup.
P/N 67130: This motor features six raw wire leads, and does not include a connector, so that it can be used with non-Sherline controllers that have a different pin configuration.
Note: Due to the lack of standardization in the industry, wire colors can vary between suppliers. If using a connector not supplied by Sherline we recommend using a continuity checker to identify which wire connects to each pin on the DIN plug. Typically, the black and white (or tan) wires are connected to the center pins, but other colors may vary. See our specifications sheet for wiring diagram.
