Technical Description: 

About the blackFoot 4x8:

The blackFoot offers precise control using 3 axes of motion. The x and y axes are helped by roller chain mechanisms at a pitch of .25". The chain and sprocket combinations are ANSI #25 specification. The z-axis uses lead screw at 1/2"-10 TPI @ 5 starts for a travel of inch with 2 turns. Accuracy and smooth operation is maintained using an anti-backlash nut on the z-axis.

All blackFoot CNC machines come with two router mount sizes. The diameter of the router mounts accept a router with a motor housing of 3.5" and 4.2". These fit the Porter Cable 890 series (2.75 HP) and the Porter Cable 7500 series (3.25 HP) routers.

With the roller chain and remarkable precision that this machine provides, you will be able to apply this machine for a wide variety of projects and machining various materials including aluminum, wood, plastic, steel and other materials. The structure is very rigid and resists lateral and bending forces to keep the machine stable throughout the machining process.

Most of the structure and design is based on the blackToe 2x4 CNC machine with a few differences. The most obvious difference is the size of the gantry. The horizontal length designed to have a y axis travel length of 4 feet. The gantry is assembled with many parts that achieve this needed size. the necessary table width to accommodate the gantry size is 52 inches. Since the #25 roller chain is relatively light, lengths of the x-axis travel can be increased comsiderably. Although rails for 8 feet of travel is provided (8 feet and 2 foot extensions), longer travels can be achieved with a longer table and added rails.
