The Bulk Man 3D WorkBee was originally designed by Ryan Lock of Ooznest UK, and it incorporates many upgrades. It is a super-strong, accurate and easy to assemble CNC machine.
The WorkBee CNC design has gone through different changes. WorkBee Version 1 originally had the leadscrews placed in compression. All Bulk Man 3D’s WorkBee kits now sold are Newest Version, with the major differences being the use of Tingle Tension System and longer leadscrews in the X and Y Axis. This helps to solve the problem of Whipping when for long length or faster Speed, which is very popular in CNC machine market.
Based on C-Beam, V-Slot, Xtreme Solid V-Wheels and TR8x8(P2) Leadscrews it is reliable. It has been carefully designed and can accurately cut foams, woods, plastics and aluminum to 0.1-0.2 mm accuracy or better.
The WorkBee CNC Machine is a 4 axis (3 + 1) machine, this means there are 3 physical axis (X,Y,Z) and a slave axis of Y which is called the A Axis. The WorkBee CNC Machine uses specific lengths of Extrusions and Leadscrews.
Advantage: This kit is the latest version comes with a new Tension System to minimise Lead Screw ‘Whip’ !
The 1.5kW Air, 1.5kW Water or 2.2kW Water Cooled Spindle Bundle contains all the hardware for mounting a the Spindle on your Work-Bee or other CNC machine.
The Cable Drag Chain bundle contains all the hardware for mounting Cable Drag Chains on your Work-Bee, Ox CNC or other CNC machine to help with cable management.
Our 6 CNC Controller Options are broken into 2 software categories： GRBL and Mach3/DrufelCNC.
- GRBL Software based controllers: xPRO V5, High Torque GRBL, MakerShield GRBL
- Mach3/Drufel CNC Software based controllers: UC300, NVUM, STB5100
These are the different software programs that are used to control the CNC Machine and send G-Code.
Our professional recommendation is the xPRO V5 CNC Controller which is the most advanced GRBL CNC Controller of its class in the world. It has 6A silent stepper drivers, WiFi and off-line options, and 4x faster than our other controllers.

Z Travel Explained
The Work-Bee has two spoilerboard support configurations. One with a travel of 66mm, and a lower one with a travel of 106mm. The reason for the two configurations is that if the machine is always used to cut thin materials, for accuracy reasons it is better to have the work piece as close to the Z-Actuator as possible, so in this case the machine should be setup in the higher 66mm travel configuration.
The higher configuration has a Z travel of 66mm, with a 12mm spoiler board, this will reduce the Z travel to 54mm. In this case 54mm is maximum thickness of material that will fit on the machine.
To calculate the max cutting depth for a chosen piece of material it is:
- Max Cutting Depth = Z travel – Material Thickness
For instance a setup with a 12mm spoiler board, the max Z travel is 54mm, so when cutting into a material 30mm thick the max cutting depth would be:
Max Cutting Depth = 54 – 30 = 24mm
This means with a 30mm piece of material it would not be possible to cut it the whole way through.
The max thickness that can be cut the whole way through is half the Z travel. So with a Z travel of 55mm, 27mm is the maximum thickness of material that could be cut the whole way through. And for the lower configuration the maximum thickness that can be cut the whole way through is 47mm.
54mm Or 94mm Travel, 27mm Or 47mm Workable depth, with a 12mm spoilerboard. The spoilerboard supports have two height configurations, these are the maximums for each configuration.
