1.1 About The Kit
This manual is for the full kit version of the WorkBee CNC Machine. Ideally, this manual
should be started straight after completing the mechanical assembly. This manual will turn
the mechanical portion of the WorkBee into a working moving machine.
Our WorkBee CNC Machine has a very large community of users, who can mostly be found
at http://openbuilds.com. It is free to sign up to this community and it will allow you to
share your builds, interact with other members, and download useful community created
resources. We have a specific build thread for the WorkBee, and we would love to see your
machines and what you make with them: https://openbuilds.com/builds/workbee-cnc-
machine.5626/.
1.2 Check Product Contents
When you receive your kit, the first thing you should do is check the contents against the
list in Appendix A. The majority of the parts will be separated into boxes that correspond
to the subsections in this manual. Additional spare small parts will be included. If anything
is missing or damaged (or if you have any other problems) please contact us at
1.3 Tools Required
•The list below shows the main tools that will be required to complete this build:
•2.5mm Allen Key
•3.0mm Allen Key
•4.0mm Allen Key
•5.5mm Spanner
•7.0mm Spanner
•8.0mm Spanner
•Hammer
•Selection of Philips Screwdrivers
•Selection of Flathead Screwdrivers
•Tweezers
•Wire Cutters/Strippers
1.4 Notes on Assembly
This manual has been written for the construction of a 750 x 750mm screw driven version
of the WorkBee. If you have a different version everything is exactly the same, with the
exception of longer V-Slot extrusions and wire routing.
The assembly has been split into 5 sections: Drag Chains Assembly, Power Supply
Assembly, Limit Switches & Wire Routing, CNC xPro Assembly, Wiring & Commissioning.
To make locating parts quicker, leave the parts in the boxes they came in when carrying
out the build.

It is recommended that you read through the whole manual before beginning the build in
order to get a full picture of the assembly process. Before beginning each step, make
sure you have studied the diagram and have the required parts in front of you. A PDF
version of the manual is available on our website and this will allow you to zoom in on the
diagrams if needed.
Be very careful to not over tighten the nuts and bolts on the plastic parts, otherwise they
may crack. Everything should easily fit together, and so if it isn’t, take a step back and
re-read the instructions.
Assembly of this kit involves the use of electricity and therefore you should take appro-
priate precautions to ensure you are assembling the kit in a safe manner. When following
wiring diagrams, double check that everything is connected correctly. Before carrying out
any work on the electrics make sure that the machine is switched off.
The polarity is indicated by the color of the wire, not by the color of the connectors at each
end. For the AC IEC input, the live wire is brown, neutral blue, and earth is green and yel-
low. For the DC Wiring of the machine a positive wire is red, negative is black, and earth
is green and yellow.

2.1 Y-Axis
2.1.1 Y-Axis Fixed End Assembly
A. Attach a Drag-Chain-Fixed-End to the Y-Drag-Chain-Fixed-End-Mount in the orienta-
tion shown above, using 3 x M5-Low-Profile-15mm bolts and 3 x M5-Nyloc-Nut’s.

2.1.2 Y-Axis Fixed End Mounting
A. Position the Y-Axis-Fixed-End-Assembly to the back left corner of the WorkBee. It
should be flush with the end of the C-Beam-750mm. Secure it using 2 x M5-Low-Pro-
file-25mm bolts and 2 x M5-Drop-In-Tee-Nuts.
