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

  • #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.
