About the Linear Controller
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.
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.
