About the Ox CNC
The Ox CNC is a simple design belt-driven CNC router. The Ox CNC was the foundation that the WorkBee CNCwas based on. The Ox CNC is incredibly simple to assemble and is suitable for millingwood, foam, plastic, soft metals and more. The Ox has gone through several versions with the most recent beingVersion 4 which has gantry plates that are designed to work with belt, leadscrew and even gear rack transmission. The Ox CNC Machine is a 3 A machine, which means there are 3 physical axes (X,Y,Z) and a slave axis of Y which is called the A Axis.
The Ox CNC is our most customisable CNC machine and can be supplied in almost any size imaginable. If the application requires a cutting area of larger than 1.5m the Ox is our solution. A common customisation of the Ox is a footprint of 3m x 1.5m which allows for a whole sheet of timber to be machined. This is incredibly desirable for woodworkers who wish to have a CNC router that can work on full sheets.
With an accuracy of 0.10-0.20mm, the Ox CNC is a great router for the hobby woodworker who wants to get into CNC woodworking. The Ox CNC also costs less than it’s Leadscrew cousins, with fewer functional parts in the bill of materials than a Leadscrew CNC machine. The Ox CNC is easily customised and adaptable, all parts of the machine are generic and modular encouraging additions and alterations after the initial mechanical build. Every Ox CNC is packed with off the shelf parts, every part is available individually from Maker Store. The modular design of the Ox CNC makes customising the mechanical build extremely easy to do and replacing any parts affordable and easy to source.
To increase accuracy of the belt and pulley transmission a system called theEverman Belt Drive System(commonly called “double belting”) can be used. This is a simple modification that reduces the flex that timing belt naturally have over long axis. Basically two belts work together to remove any stretch that is experience in the timing belt so that the only stretch is less that 30mm between the wheel and pulley.This system is explained in detail here.

Cable Management System
When wiring up a CNC Machine, even a simple CNC machine, there will be a lot ofcable runsthat are needed for all the components of theelectronic system. These cables will quickly start getting in the way of moving parts and if there is no cable management there is a serious risk of damaging cables which can be extremely unsafe when the CNC machine is operating.
Simply cable tying the cables to your frame will not work because the CNC machine axis are constantly moving, so the cables too must move with the axis.
Cable Drag Chainsare a solution to cable management.When it comes tocable drag chains, if you have the space for them, the larger the better. It is easier to feed a new cable through a larger drag chain than it is trying to force a cable through an already full smaller drag chain. Cable Drag Chainsvery quickly fill upwith the numerous cables that are running around the CNC Machine.
Our15x30mm Cable Drag Chains have each individual link able to be opened up, this is an incredibly useful feature the smaller drag chains do not have. Drag chains can be shortened or lengthened by simply removing or joining links of the chain.
Electronic System
When it comes to deciding on an electronic system to control your CNC machine there are many opinions on the options to choose from and researching these can lead you down a rabbit hole. However, a great place to start is with the software. The choice of software to control your machine will dictate the options available for electronic hardware.

Our Recommended:
The E5X MCS T4.1 is Maker Store’s most recommended CNC Controller for all CNC enthusiasts. Whether you are a professional or a hobbyist, E5X MCS is the right choice for your application.
The E5X MCS T4.1 is an Ethernet-controlled 5-axis Motion Control System based on Teensy 4.1 that has been designed and is certified Australian made.
It is an easy-to-use and powerful CNC motion control system capable of controlling 5-axis CNC machines. As CNC machines evolve, there is a great demand for high-performance CNC controllers such as the E5X MCS.
The E5X is a powerful 32-bit CNC controller, running on grblHAL firmware which is fast becoming the firmware of choice for CNC control due to increased functionality and added features, far superseding the current 8-bit CNC controllers running on the standard grbl or grbl esp32. Depending on the user’s requirements, E5X MCS can be connected via a USB or ethernet interface.
The layout of E5X MCS has been designed with ease of use and practicality in mind with inputs and outputs easily accessible via secure and pluggable connectors. The E5X MCS is pre-configuredand is ready to use right out of the box.
Other Options:

The xPRO V5 Motion Control System is our easiest to set up and learn and most user-friendly electronic control system. | High Torque GRBL System This electronics bundle is the most flexible and adaptable CNC control system we offer. This system does take a bit more to set up, but can be adapted and changed to suit a vast range of different applications. |
| CNC Cable Pack This cable pack contains all the necessary cables for controlling 4Stepper Motorsand 3Limit Switches. We use these in ourCable BundlesandElectronics Bundles. This is the perfect choice if you are using your own Electronics. | Maker Shield GRBL System The Maker Shield is an all in one GRB1.1 solution for CNC control designed for use with the Arduino® Uno andUno compatible controller boards. This shield features 4 embedded DRV8825 stepper motor drivers making configuring and setting up your system an easy plug and play exercise. This option is best suited to standard Nema23 Motors. |
Spindle / Router Mount
ASpindle/Router Mounting Bracketis the best choice if you are using a standard Makita/Dewalt/Bosch router. Check the diameter of your router before choosing the size.
The400W Air Cooled Spindleis a DC motor similar to a router. This spindles is relatively safe to use and runs on 48VDC. If a fault condition ever occurs no serious harm will come to the user. Small spindles such as this can perform the same cuts and run times as a standard router. The run out for the 400W Spindle is generally more accurate that a router.
Touch Probe
There are two options when selecting a Touch Probe.
One is a simple touch probe used for correctly offsetting the Z Height from the workpiece prior to beginning a job. The other option is an XYZ Touch Probe that is used to accurately set the 0, 0, 0 coordinate of the workpiece prior to beginning a job.
