Product Description

If you wish to purchase a Sherline CNC lathe but want to use your own computer and software instead of Sherline’s computer with pre-loaded Linux/EMC software, this package makes it easier. Here’s what you do:

  1. Order the CNC-ready lathe of your choice.
  2. Order this kit (4-axis driver box, connecting cables, power supply, and two high-torque stepper motors). The high-torque stepper motor has the same NEMA #23 frame as our standard stepper motor, but it has over 75% more torque. For more information on the high-torque stepper motors, CLICK HERE.
  3. Supply your own computer, monitor, and control software.

This kit includes Sherline’s 4-axis driver box, power supply, and two high-torque stepper motors. Plug the 25-pin parallel cable (included) from the driver box to your computer’s printer port. Attach the stepper motors to the stepper motor mounts on the crosslide and leadscrew of your Sherline CNC-ready lathe, and plug the X and Z cables from the driver box to the stepper motors. You are ready to go once you select and install your own control software.

NOTE: If you want a complete plug-and-play system with a lathe or mill, computer, and driver ready to run, see the complete CNC systems listed elsewhere on this site

Included Components

  • Driver box with 4 motor cables
  • 3.7 amp, 24-volt power supply with cord
  • 25-pin parallel cable*
  • 2 CD set with Linux/EMC2, utilities, and instructions
  • Two spare fuses

*NOTE: A 25-wire parallel port is required because EMC2 is designed to be capable of running up to six axes simultaneously. Even though the Sherline driver box only uses four of those axes at one time, a 2-wire serial USB port cannot transmit data to multiple axes fast enough for glitch-free CNC operation.

Minimum Computer Requirements

In order to install and run a Linux-based system from the disc provided, it is recommended the computer have at least the following minimum specifications:

  • Processor speed: 800 MHz or faster (Pentium III class or equivalent processor)
  • RAM: 512 Mb (Sherline provides 1 Gb)
  • Hard Drive: 20 GB or larger
  • 25-pin parallel port (printer port)
  • (Laptop computers are not recommended.)

Driver box available for OEM

The Sherline driver box is available for manufacturers wishing to put together a CNC system of their own. Why reinvent the wheel? This box and Sherline’s pre-wired stepper motors make it easy to assemble a custom CNC package. Contact Sherline for details on our OEM quantity pricing. We have also left plenty of space on the top of the unit to laser engrave your logo and company information and can handle that for you in-house. In addition, OEM suppliers using our driver box will be provided a link and a 300-word description at no charge on a special page on our website to describe your product.

Linux vs. Windows

The software that comes with this package includes Linux and LinuxCNC (formerly EMC) on DVD-ROM. CLICK HERE to learn more about the advantages of Linux and how it compares to Windows. Please read this if you are unsure about your ability to install Linux yourself on your own computer.

For Windows® Users Only Now available for Windows 10, 32b, and 64b

uc100Use your own laptop or desktop via the USB port with Sherline’s CNC Controller. New from DPP Engineering is this new USB CNC to LPT motion controller. This product contains a microprocessor that simulates a complete CNC controller program and thus elevates the processing load from the host computer.

Power Supply Input: 100-240 VAC, 47-63 Hz, 3A (automatically adapts to incoming voltage)
Output: 24 VDC, 4A
Parameters Logic high levels should be greater than 2 volts.
Logic low should be less than 1/2 volt.
Step pulses are active low.
Step pulses should be at least 22 microseconds long.
The lines labeled as LinuxCNC inputs or outputs can be disregarded in other systems.
For use with software other than LinuxCNC, make sure your software addresses the correct I/O lines for step and direction as shown below. Sherline is not able to provide assistance for other programs. For help with the LinuxCNC software, see www.linuxcnc.org/
We recommend at least an 800 MHz Pentium class computer or faster for use with the frequency mode.
In operation, the power to the motors will be reduced to half current after 3 seconds of inactivity. This can be changed to 1/4 power with a jumper on H1.
