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.

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.

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.)
An 8-pin mini-DIN cable allows multiple controllers to be connected in a "daisy-chain" configuration. Controllers can signal one another to run in sequence, enabling complex, multi-axis movements without a computer or master CNC controller. The controller also integrates easily with existing CNC systems. Each controller stores two independent programs with up to 40 steps per program. Each step can define travel distance, direction, feed rate, and whether the sequence pauses or continues automatically.
The linear controller can also be daisy-chained with Sherline’s rotary controller (P/N 8700), allowing combined rotary and linear motion for advanced operations—such as gear cutting—without the need for CNC programming skills beyond simple keypad inputs.
Included with the CNC Linear Controller:
-
Linear controller with integrated keypad
-
Power supply
-
#23 frame size stepper motor
-
Cables
-
Stepper motor mount
-
Dampened coupling
-
Preload nuts
-
Drill guide block
-
Complete installation and operation instructions
Power Supply Compatibility:
The included power supply is compatible with 110–240 VAC and automatically adjusts for global use (220–240V). Earlier versions of this product shipped with 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.)

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.
