Recently, a wood working friend on Twitter asked for my advice. He wanted to know if their were any inexpensive CNC router tables that won’t break the budget? CNC router tables can be an expensive investment in your woodworking hobby, but I feel it brings a variety of new options to your woodworking. My first response was to ask an what his budget was for the project. When he responded that he would like to spend between $500 and $1000 including software, I knew he was in for a shock. I told him that he could expect to spend about as much on a CNC router table as he would spend on a SawStop table saw (or two). He was understandably disappointed by my response, but it got me thinking. Was it possible? Here is what I found out.
The marketplace for CNC router tables has been changing rapidly. As more and more people choose to bring CNC machines into their workshop, the number of choices has gone up while the price has gone down. While it is still tough to find a CNC router table for under $1000, it is not impossible. Finding one that includes software at that price would be unusual.
One thing to consider before buying any CNC equipment is what your intended use is. If it is light duty CNC work than any of the machines listed below will work. However if you intend to machine aluminum or brass you may need to consider a larger more rigid machine. You should also be aware that I have no personal experience with any of the machines listed below.
There currently several small companies which offer CNC kits that won’t break the budget. Some of the kits listed below are more expensive than the original $1000 budget. However, all of the kits listed are available at or below the cost as a Sawstop Cabinet saw.Digirout 200cost $1900http://www.digirout.com/dr200.html
The Digirout 200 is a small CNC router table with a two foot square cutting area. This router comes as a kit and must be assembled by the owner. The construction is mostly aluminum extrusion and powder coated steel parts. It includes an aluminum T-Slot table to make holding down your work-piece easier. It is designed to work with a Porter Cable 892 router and mount And will cut at 100 inches per minute. At roughly $2100 for the kit you will have close to $3000 invested including software.
CNC Kit Features:
*3″ x 6″ bridge with a 3″ Z travel ,
*CNC fabricated structural steel gussets.
*Aluminum extruded frame
*High speed gothic arch linear bearings
*Precision hardened & ground linear guidance railsThe Nomad 883Cost:$2,499.00http://carbide3d.com/
The Nomad 883 is the result of a kickstarter project. I believe it is aimed at those who are fascinated by the 3D printer craze. The stated goal of the company (Carbide3D ) was to take the guesswork out of operating a CNC machine. Everything you’ll need to get started is included – software (for Mac and PC), cutters, cables, even a starter pack of material.
The Nomad 883 is fully enclosed in a cabinet to help control the dust and limit the noise. To further reduce noise, the Nomad 883 does not use a router motor. Instead it uses a Brushless DC motor and a belt driven spindle. Since the speed control features a closed loop system, you should be able to control spindle speed from withing the software.
The overall cutting area is small at 8″x8″x3″ but the size is comparable to that of a 3D printer. Unlike many 3D printers the Nomad 883 is not flimsy. It features an all aluminum frame, precision ground rods and linear bearings.
Lastly, the Nomad 883 comes equipped with Carbidemotion and Meshcam so there is no need to buy additional software. However, if you would like to use another CNC software the Carbidemotion software will accept g-code from most packages.Bluechick 13×36 Desktop CNC RouterPrice: $1620.50https://www.buildyourcnc.com/DesktopCNCMachineKitblueChick.aspx
The BlueChick is a Build it yourself CNC Router table. It uses CNC cut MDO (Medium Density Overlay) plywood parts and aluminum angle stock to build a 13″x36″x4″ machine. The drive system uses a timing belt and pulley system instead of leadscrews. This system allows the BlueChic to move at 500 Inches Per minute.
The gantry of the machine moves on V-bearing riding on angle iron. While this is not my favorite system it is functional. The steel V-bearing will wear out the aluminum angle in a few years but they are easily replaced at a local big box store.
The BlueChic uses Mach3 for the CNC control software. Mach3 is widely used and is my personal favorite for control software. It also support LinuxCNC a free opensource control software. LinuxCNC is good software and many people swear by it. Either piece of software will control your machine just fine.
CNC Kit Features:
*13″x36″x4″ Travel.
*Can cut virtually any material
* X and Y movement speed 500 IPM (inches per minute)

Two machines in this report are the low cost leaders. The first has to be the Zentoolworks CNC Carving Machine F8 version. This is the 12″x12″ DIY CNC kit with F8 Leadscrew on all three axis. The frame is constructed with high density PVC boards, steel guide rods, linear bearings and stainless steel lead screws. The leadscrew features an anti-backlash brass nut design to help reduce backlash.
Assembling the CNC Carving Machine only takes around 3-4 hours to complete. There is an active WIKI Website for up to date instructions. Obviously, a PVC machine is not as ridgid as an aluminum machine but it is still a nice workable system for light duty CNC work.
The CNC Carving Machine is not a complete kit. You will need a 3 Axis Stepper Motor Driver to manage the motors, a spindle/cutter with mounting brackets, a DC power supply for both and you will also need a computer with a standard printer port and CNC control software.
CNC Kit Features:
*12(X) x 12(Y) x 2(Z) inches travel capacity
*PVC Frame, Steel guide rods and precision linear bearings provide maximum accuracy and rigidity
*3 x New Nema 23 Stepper Motors included (2 Phase, 4 Wires, 1.5A, Bipolar)

The following illustrations show 17 ways of how to attach the tabletop to the table structure.
We have prepared a 3D view and 2D drawings to make it easier for you to understand how each of the methods really works.
At first, the answer to the question of how to fasten a tabletop to the table structure may seem very simple. Only when we look at the problem a little closer we can see that this is not an easy task. The way in which we should fasten the tabletop must meet several criteria:
*the tabletop must be firmly fixed to the table structure;
*with time, the tabletop must remain flat and undeformed;
*the attachment method shouldn’t compromise the design of the table.
Properly installed, a tabletop can contract and expand with changes in humidity while staying flat and firmly connected to construction of the table.
Wood is hygroscopic, which means that it gains or loses moisture from the air, and this is always dependent on the surrounding conditions. If the humidity of air is increased, wood absorbs moisture and thus starts expanding. If, on the other hand, the humidity of air is decreased, wood releases accumulated moisture and starts shrinking. Wood’s movement (difference in dimensions due to expansion and shrinking) can be significant (especially for large tabletops). In case that movement is disabled, the tabletop will start to deform and crack. The most dramatic movement occurs acroos the grain. Movement along the grain is so small that it can be ignored. To what degree the movement will occur, depends on the following: width of the tabletop, type of wood, initial moisture content of the wood, range of humidity extremes..
There are two groups of methods to fasten the tabletop to the table structure:
*Free-moving fastening method – allow expansion and contraction of the wood
*Stationary fastening method – keep the tabletop stationary. This method is usually employed where tabletop is of frame construction, made of laminated materials or for smaller tables where the tabletop is not large enough to produce much movement.- Free-moving tabletop fastening method
1. Button fasteners – As the tabletop expands and contracts, button fasteners are free to slide within the groove. Grooves can be made along the entire apron, or to be slightly longer than the button width. Easy to make and install, it allows movement in two directions (along the apron and perpendicular to it).
2. Button fastener with kerf – This method is similar to the previous one, the only difference is that the kerf under the working end of the button can be bent up or down. This bending can be very useful if you have a groove made a little higher or lower than it should be. Grooves can be made along the entire apron, or to be slightly longer than the button width.
3. Metal table clips (Z fastener, S-shaped clips) – Z-fasteners are a metal version of the button fasteners. It is an inexpensive and easy to install, and allows for a great deal of wood movement.
4. Flat twin circle clip (figure 8 clip, or figure 8 fastener) – Easy to install and inexpensive. The shape of the figure 8 fastener allows them to pivot as the tabletop expands and contracts. Depending on accessibility, these fasteners can be installed on the inside or outside of the apron.
5. Cleat with slotted hole (wooden blocks) – Glued to the apron and screwed to the underside of the tabletop. Block must be designed so that the long grain (not the end grain) is glued to the apron. If the block were made without a groove, this way would fall into the stationary method.
6. Screw block (cleat) – This method is similar to the previous one, the only difference is that the block is fixed to the apron with wood screws and not by gluing. If the block were made without a groove, this way would fall into the stationary method.
7. Dovetail block – allows the most movement but is the hardest to make. A dovetail shaped part is screwed to the tabletop, and a block with corresponding slot is glued to the apron.
8. Beveled cleat
9. Dovetail cleat – Slot and dovetail cleat taper 1/16in. in width from one end to the other. The dovetailed cleats keep a tabletop flat, and they also allow movement.- Stationary tabletop fastening method
10. Pocket hole – great for small tables. The holes are drilled at an angle of 10 degrees. Pocket holes can be made to allow for slight movement of the tabletop in two ways: by drilling slightly oversized pilot holes or by making the holes oval in the direction of movement.
11. Corner iron
By making grooves instead of holes, this method would become a free-moving fastening method.
12. Dowel
13. Screw – If shank hole and counterbore are oversized, this will allow the tabletop slight movement.T-slot Table Top
14. Screw and plugs
15. Top pin – Top pin can be tapered or threaded. This method is suitable for heavy and large tables that often need to be moved when expanded. In the past, it was mainly used for tables in pubs, butchers’ tables and the like.
