Linear Controller without Power Supply
The stand-alone controller is fully programmable via its built-in keypad and manages the operation of the connected stepper motor.
An 8-pin mini-DIN cable allows multiple controllers to be linked in a "daisy-chain" configuration. The controllers can signal each other to operate in sequence, enabling complex, multi-axis movements without the need for a computer or master CNC controller. They can also be used alongside existing CNC systems. Each controller can store two independent programs, with up to 40 steps per program. Each step can define distance, direction, speed, and whether the program pauses or proceeds automatically to the next step.
Sherline’s linear controller can also be daisy-chained with the rotary controller, allowing combined rotary and linear operations in sequence. This setup simplifies advanced tasks—such as gear cutting—without requiring CNC programming knowledge beyond what is entered via the keypad.
Items Included with the Linear Controller:
-
Linear controller with integrated keypad
Controller Power Supply Information:
The optional power supply is compatible with 110-240 VAC and automatically switches between voltages for use in regions with 220-240V mains power. (The original version of this power supply was 110 VAC only.)
CNC Linear Controller with Power Supply
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.

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.)
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
Programming is simple and intuitive. Stored programs can be run repeatedly at the push of a button with excellent repeatability and accuracy.

Power Supply Compatibility:
The included power supply operates on 110–240 VAC and automatically adjusts for global use (220–240V). Earlier models of this product shipped with a 110 VAC-only power supply.
CNC Linear Controller with 24″ Leadscrew
This CNC power feed includes a stepper motor mount and a 24" leadscrew for use with 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 can be mounted to drive the leadscrew of the lathe.
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 requiring a computer or master CNC controller. The controller can also be used in combination with existing CNC systems. Each unit is user-programmable with two independent programs of up to 40 steps each. For each step, you can set travel distance, direction, feed rate, and whether the sequence pauses or proceeds automatically.
The linear controller can also be daisy-chained with Sherline’s rotary controller (P/N 8700) to combine rotary and linear movements. This makes it easy to perform advanced tasks—such as gear cutting—without any CNC programming knowledge beyond the keypad interface.
Advantages of Using a Power Feed:
-
Provides a constant feed rate for a smoother, more consistent surface finish
-
Reduces the chance of errors caused by miscounting handwheel revolutions
-
Eliminates physical effort for long cuts or returning the saddle to the starting position
Programming is quick and straightforward. Stored programs can be executed repeatedly at the touch of a button with high precision.

CNC Linear Controller – X/Y-Axis Upgrade
This kit upgrades the X- or Y-axis of a manual Sherline milling machine or the crosslide of a Sherline lathe for use with a CNC linear controller. It includes a CNC linear controller and all the components required to convert a manual axis to CNC operation. The linear controller comes with a stepper motor mount for machines that are not CNC-Ready.
The stand-alone controller is programmable via its integrated keypad and controls the attached stepper motor, which can be mounted on the mill’s X- or Y-axis or the lathe’s crosslide. (For lathe leadscrew upgrades, click here for 15" upgrade kits or click here for 24" kits.)
