Sherline PN 8771 4 axis controller, Power Supply + 3 High torque Stepper Motors

Description

About the CNC Mill Kit Upgrade to full CNC using your own computer
If you wish to purchase a Sherline CNC mill, but you 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:
Order the CNC-ready mill of your choice.
Order this kit (4-axis driver box and connecting cables plus power supply and 3 high torque stepper motors).
Supply your own computer, monitor, and control software.
The 8771 kit includes Sherline’s 4-axis driver box and power supply plus three (3) X 67126 High torque stepper motors
pre-wired in a connector that plugs directly into the Sherline
CNC controller.
A 25-pin parallel cable (included) from the driver box to the printer port of your computer. (For USB users Please search for 8770 _ USB + MACH4.)
Attach the stepper motors to the stepper motor mounts on the on the X, Y and Z axes of your Sherline CNC-ready mill and plug the X, Y and Z cables from the driver box to the stepper motors. Once you select and install your own control software, you are ready to go. If you want to add a 4th axis rotary table, purchase P/N 8730 rotary table with stepper motor and plug it to axis A.
Included Components
Driver box with 4 motor cables
3 X Stepper motors (PN 67126) With plugs and adopter.
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.
Note on Linux & Windows
The software that comes with this package includes Linux and LinuxCNC (formerly EMC) on DVD-ROM. Nevertheless, this CNC system can also work very well with Windows based OS using either MACH4 or MACH3 CNC software.
If you wish to run your Sherline Mill from your Laptop/Desktop USB port using the 8771 kit. Please search eBay for: 8771 + USB + MACH4 (For Windows OS only)
