The gantry design is a proven design for "do it yourself CNC routers." However, there are still many things that you should be aware of. From a design standpoint, you want your gantry to be stable and balanced. Design the CNC gantry to meet the forces that it will encounter.

Fixed gantry (moving table) CNC routers are simpler to design build and maintain. They are inherently more rigid compared to moving gantry machines because the X-Axis beam assembly is fixed in place. Because it is stationary, any added structural weight improves performance with no negative effects.

Design and build details of my custom CNC Router including CAD files, drawings, and build details. This is a steel fixed gantry style router built specifically to tackle machining aluminum.

There basically are two types of CNC routers: the moving table design and the moving gantry design. Moving table style designs are often used for smaller size CNC routers. They are easier to construct and can be built more rigid than a moving gantry style machine.

Below you can see two examples of Z-axis assemblies with the Y-Axis CNC Router Gantry in the background. As with the previous discussions, when designing or building a CNC router it is important to consider the forces that are evolved.

Jul 1, 2011 · Do it yourself CNC router: Design Considerations, the Gantry With 3 ft of unsupported rail this torque might be something to take into consideration. In either design the rails have to support a weight, either gantry or table+work.

For typical gantry routers, the ‘Y’ axis moves relative to the fixed workpieces, while the ‘X’ axis is on a gantry that moves perpendicular to the Y axis. The ‘Z’ axis moves relative to the X axis and perpendicular to both other axes, typically with a fairly short stroke on most routers.

Nov 25, 2015 · The newest plate C-Beam™ Gantry Plate - XLarge resolves a lot of those issues and now provides a solution to building fairly stout routers without custom plates as shown in Mark's most recent design shown here.

Nov 9, 2015 · I am fortunate enough to have industrial CNC machinery at my disposal, so it was an obvious choice to machine all of the mechanical parts for this machine myself. This blog post gives a brief overview of the process. The largest and most challenging components to machine were the Gantry Side Plates. I began with 19 mm…
