OX CNC Assembly Instructions 2 v1.1
© Bulk Man 3D 2019
About The Ox CNC Kit
The mechanical kit is based on the Open Builds Ox CNC Router designed by Mark Carew and
published on openbuilds.com. There are however a couple of difference between Mark’s design and
this Ox Kit. None of the differences are that great and the Openbuilds YouTube videos available on
putting the Ox together are a great resource and starting point for everyone. Most of the differences
are a result of customer feedback and modifications published on a wide number of internet forums.
Please note that while we have spent a considerable amount of time and effort putting these
instructions together, any errors and omissions excepted (E&OE). If you find an error, please let us
know so we can continually improve this resource.
Unpack and Check All Components
Before starting any build, it is always a great idea to get organised. Start by unpacking your kit and
checking it against the BOM (Bill of Materials) in Appendix 1. If you find any parts missing, please
contact us as soon as possible.
Tools Required
You will also need the following tools:
•3mm Allen Key
•8mm Spanner
•10mm Spanner
•Screw Drivers
•M5 Tap
•Hack Saw (or other means to cut V-Slot)
•Builder‘s Square
Pre-Assembly Notes
1. While these instructions have drawings for the Large Ox, construction of the Small Ox is, in
principle, the same.
2. It is Important to make sure all angles are square. As you progress through your build, use
the Square to make sure everything is aligned before the final tightening of all screws and
nuts.
3. This build requires some of the V-Slot to be tapped with a M5 tap. In general tap to a depth
of 8-10mm. and clean away any swarf and burs.
