CNC Linear Controller with 15″ Leadscrew
This linear controller package includes a stepper motor mount and a 15" leadscrew for use on Sherline lathes that are not CNC-Ready. The stand-alone controller is programmable through its integrated keypad and directly controls the attached stepper motor, which is mounted to drive the lathe’s leadscrew. (A separate kit with a 24" leadscrew is available for 4400-series lathes—P/N 8880.)
An 8-pin mini-DIN cable allows multiple controllers to be connected in a “daisy-chain” configuration. The controllers can signal each other to operate in sequence, enabling complex multi-axis operations without the need for a computer or master CNC controller. The system can also be used in conjunction with existing CNC controllers. Each unit can store two separate programs, with up to 40 steps per program. For each step, you can define travel distance, direction, feed rate, and whether the sequence pauses or advances automatically.
The linear controller can also be daisy-chained with Sherline’s rotary controller (P/N 8700), allowing coordinated rotary and linear motion. This makes it easy to perform sophisticated operations—such as gear cutting—without any CNC programming knowledge beyond the keypad interface.
Advantages of Using a Power Feed:
• Maintains a constant feed rate for smoother, more consistent surface finishes

• Minimizes errors from miscounting handwheel revolutions

• Eliminates physical effort during long cuts or when returning the saddle to the starting position

CNC Linear Controller with Stepper Motor
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

Stepper Motors
Sherline stepper motors are NEMA 23, dual-shaft motors designed specifically for our CNC mills, lathes, and rotary tables.
Both the standard motor (P/N 67127) and the high-torque motor (P/N 67126) are rated at 2.0 A/phase and are fully compatible with Sherline CNC systems, driver boxes, and motion controllers. The dual-shaft design allows you to add handwheels for manual control when needed. [accordion] [pane title="Features"]
• NEMA 23 frame size – fits Sherline CNC-ready mills, lathes, and rotary tables.
• Dual-shaft design – both ends of the shaft are usable; flats are ground on each end for secure attachment of handwheels and couplings.
• Standard step angle – 1.8° per step (200 steps/rev) for precise motion control.
• 2.0 A/phase – both motors are rated at 2.0 amps and work with existing Sherline CNC power supplies and driver electronics.
• 6-lead wiring – allows use in a variety of bipolar or unipolar configurations (see spec sheets for wiring diagrams).
• Designed for Sherline CNC – plug-and-play with Sherline driver boxes and motion controllers when used with the supplied connectors.
[/pane] [pane title="Motor Options"]
P/N 67127 – Standard Stepper Motor (with Plug)
The standard Sherline stepper motor (P/N 67127) comes pre-wired with six leads into a 5-pin DIN connector that plugs directly into Sherline’s CNC driver boxes and linear or rotary controllers. Simply plug each motor into the corresponding axis cable for a quick, clean setup. This motor is ideal for typical Sherline CNC applications where cutting loads are moderate, such as machining aluminum, brass, plastics, and light cuts in steel.
P/N 67130 – Stepper Motor (Without Plug)
P/N 67130 is the same basic motor as P/N 67127 but supplied with six raw wire leads and no connector. It is intended for non-Sherline controllers or custom installations where a different pinout or connector is required.
P/N 67126 – High-Torque Stepper Motor
Sherline’s high-torque stepper motor (P/N 67126) uses the same NEMA 23 frame size and 1/4" dual shaft as the standard motor, but delivers over 75% more holding torque. This added torque is especially useful on the Z-axis, where it can better handle the weight of the headstock and motor, and for heavier cuts or higher feed rates. Rated at 2 amps, the high-torque motor is fully compatible with all Sherline CNC machines, including complete CNC systems, the 4-axis driver box, CNC rotary tables, and Sherline linear and rotary controllers. No power supply upgrade is required. [/pane] [pane title="Specifications Comparison"]

[/pane] [pane title="Compatibility & Installation Notes"]
• Coupler requirement: Because of the increased torque, the high-torque motor (P/N 67126) must be used with the updated CNC coupling (P/N 671052). This coupling replaces the older 3-slot coupling (P/N 67105).
• Motor mounts: When used with a Sherline stepper motor mount (P/N 67101), be sure that the shaft entering the coupling has a flat aligned with the set screw. Tightening against the round shaft can damage the shaft and make removal difficult.
• Handwheel use: The dual-shaft design lets you mount a handwheel on the rear shaft for manual operation when the drivers are powered down. When the motors are energized, they hold position and cannot be moved easily by hand.
• Controller compatibility: P/N 67127 with the 5-pin DIN plug is designed to plug directly into Sherline’s 4-axis driver box, CNC systems, and linear and rotary controllers. P/N 67130 (no plug) is intended for non-Sherline or custom controllers.
Safety Note: The improper use of machine tools and accessories can result in serious injury. Always read and follow the instructions before installing or operating stepper motors, and always wear appropriate eye protection. [/pane] [pane title="Documents"]
