Which option is best for you?
There are 4 different options to choose from depending on if you already have a WorkBee, and what version you have.
This Mechanical kit comes with 4x Nema 23 Stepper Motor 2.45N.m-High Torque.If you need the Black Extrusion please feel free to contact us.
The Mechanical Kit comes with all the parts to assemble the QueenBee PRO. If you are not upgrading an existing WorkBee CNC Machine then this is the option you require.
The Upgrade Kit comes in three types;
- Upgrade for WorkBee V1 (pre Nov-2019). If your WorkBee has the shorter lead screw lengths that finish flush with the end plate then this upgrade is required. This upgrade includes the QueenBee PRO features, longer lead screw lengths and lead screw tensioning system.
- Upgrade for WorkBee V2 (Nov-2019 – Mar-2020). If your WorkBee has the upgraded longer lead screw lengths that protrude out the end plates and the tensioning system, however does not have thrust bearings then this is the upgrade required. This upgrade includes the QueenBee PRO features and new thrust bearings for the lead screw tensioning system. This upgrade does not include new lead screws. (This option is best for Non Bulk-Man 3D V2 machines)
- Upgrade for WorkBee V2.2 (Mar-2020 onwards). If your WorkBee has the upgraded longer lead screw lengths that protrude out the end plates, and the Tingle Tensioning System that includes the thrust bearings on the outside of the end plates then this is the upgrade required. This upgrade includes only the QueenBee PRO features. This upgrade does not include new lead screws or new thrust bearings.
If you have a belt-drive WorkBee machine please contact us as you require additional hardware. If you have any questions regarding which option your require please contact us so we can assist you.

Bulk-Man 3D is the largest wholesaler of Open Source CNC parts to the world. By having the parts produced ourselves, or sourcing the parts directly from the factory, we eliminate the middle man and in doing so are able to provide the best wholesale price direct to the public!
The age old issue of flex in the X-Z axis on the WorkBee CNC was a common topic when considering upgrades for the machine. The main solution individuals came to was replacing the V-Wheels with Linear Rails to increase overall rigidity and accuracy as well as reduce chatter when working on metals.
After many CNC owners and members of the community approached us requesting a high quality linear rail solution for their machine at an affordable price, our technicians worked hard researching different options available and ways we can improve on existing designs. The result of the project is the QueenBee PRO CNC Machine.

QueenBee PRO features
The QueenBee PRO has some very impressive features that have been introduced. Some examples include:
|Upgraded Plate Set Design for all axis. The new plates have many key features including;
|High Quality Precision Linear Rails for the entire motion of the axis|
|Upgraded Specialised Nut Block Spacer|
|Reduces almost all X-Z Axis ‘flex’ with strengthen linear rails and additional bracing|
The original QueenBee design was a good foundation for the Bulk-Man 3D linear rail upgrade, however it had some limiting features that were overlooked. After feedback we received from individuals upgrading their machines to linear rail, some features of the original design were identified as problems and we worked on creating solutions in order to make the QueenBee PRO an even more reliable and rigid design.
Some upgrades to the original design include:
|Standoffs for the ACME nut blocks.
The original design spaced the nut blocks using the bolt and standard metric spacers. While this worked, the nut blocks were very easy to misalign and adverse movement of the nut blocks resulted in the feed rate being limited. The QueenBee PRO overcomes this issue by securing the nut blocks in place using a specialised spacer block. With our new specialised secure spacer block there is no unwanted movement in the nut blocks due to the extended standoff.
|The X and Z Plate design allows for easy adjustments of the ACME Nut Blocks after installation
If you have assembled a CNC Machine you know there is nothing more frustrating then having to disassemble parts just so you can adjust one component. Our new design has worked to make adjustments easy even after assembly.
|Extrusion inserted inside the Y-Axis C-Beams making the axis stronger
The empty space inside the C-Beam has been filled in to make a super rigid true 8040 profile.
|Y-Axis End Plates have been re-designed to increase the rigidity of Y-Axis, as well as correctly align the Lead Screw for the new HGR Rails
With the HGR rails and bearings spacing the gantry further from the extrusion the ACME Lead Screw has been cleverly positioned accordingly.
|Y-Axis Gantry Plates have been re-designed to include additional mounting positions to secure X-Axis and increase Y-to-X Axis rigidity.
A stronger Y-to-X Axis design has been introduced to reduce the chance of any axis ‘twist’.
|Extrusion secured to the back of the X-Axis to reduce flex and increase rigidity
By fixing extrusion to the back of the X-Axis the overall rigidity has been increased substantially.
|All plates are designed for the Bulk-Man 3D Tingle Tensioning System
Our Tingle Tension System to reduce lead screw ‘whip’ is a key feature in all new lead screw driven designs.
|New and improved rigid spoilerboard design
A stronger spoilerboard makes the baseboard installation both easier, and more stable.
|Heavy Duty Slide in T-Nuts
The Linear Rail is secured to the extrusion using Heavier Duty Slide in T-Nuts rather than the light duty Drop-In T-Nuts.

About the ‘QueenBee’ name
CNC Machine designs evolve through community modifications and version upgrades. The benefit of the nature of the OpenBuilds style CNC machines means that designs can always be upgraded and improved on.
First there was the Shapeoko by Carbide 3D, then ROUTY by OpenBuilds followed by the famous Ox CNC which was a V-Slot machine based on the Shapeoko. After some time Ooznest developed the WorkBee which was based on the foundation the Ox design laid. The WorkBee has since gone through several versions, with the most recent version using the Tingle Tension System introduced to the market by Bulk-Man 3D. Working to create a linear rail upgrade CNC3D created the QueenBee upgrade as a linear rail option designed to work with Bulk-Man 3D WorkBee CNC Machines. We made this linear rail upgrade the foundation of our own linear rail upgrade, however we have made several changes to the design to improve the machine.
There have been a few different ‘linear rail upgrade’ designs over the years to suit the WorkBee, Ox and Lead CNC Machines. A well known upgrade for the Bulk-Man 3D WorkBee CNC Machine was the QueenBee. The original QueenBee upgrade paved the way for the Bulk-Man 3D QueenBee PRO, and the name ‘QueenBee’ has become a common description for linear rail modified WorkBee machines.
As this machine is still an upgraded linear rail WorkBee design, the name ‘QueenBee’ seems fitting however with the changes and improvements made to the new and improved Bulk-Man 3D design, the name given to this WorkBee Upgrade is the QueenBee PRO.

What is the benefit of upgrading a WorkBee to a QueenBee PRO?
The WorkBee is a very clever and strong design, it has been our recommended machine for many years and has served the CNC community well. However when the WorkBee was first designed, the frame size was 750mm along the longest axis. This worked very well when paired with a small router in a woodworking hobby application. The WorkBee design began to show some weaknesses when pushed beyond its original design as demand called for heavier spindles to be mounted to the machine, longer axis for enlarged workable areas, and capabilities of working with stronger materials such as aluminium.
The QueenBee PRO is the perfect solution to these weaknesses. The upgraded strengthen plates and extrusion layout paired with the precision linear rail system allow for heavier tools such as a 2.2kW and even a 4kW Spindle to be mounted to the machine. The increased rigidity of the linear rails on all axis reduces twisting of the axis and flex in the gantry observed on the WorkBee due to heavier tools being used.
The QueenBee PRO creates a smooth and precise finish when milling aluminium and other soft metals by reducing chatter. The common ‘lead in’ and ‘lead out’ trail observed with machines using V-Wheels operating at high feed rates has also been eliminated. Faster cut times and operating speeds are now possible.
When upgrading an existing WorkBee to a QueenBee PRO design, the WorkBee will need to be almost completely disassembled.
Lubricant for the bearings is applied when they are manufactured however routine maintenance and re-lubricating is recommended, especially in high dust applications such as MDF.
