The BlackBee CNC takes a massive  step in the performance of Openbuilds type CNC machines.



Buy once.. Buy the best. Is the motto for this kit because without any doubt this is the best kit in its class. We do not state that lightly, we have designed this kit to be the very best, the most rigid, the easiest to assemble, and above all we have raised the bar very, very high for this kit and the class of CNC kits the kit has as competition.


Buy Once.. Buy the best... simply means, when you purchase the BlackBee CNC kit you receive everything that the other kits in the same class add on later.. don't add on later, buy included!


Unique out of the box thinking has allowed us to create the ultimate CNC kit in its class, dynamic 12mm diameter Ball screw motion, with integrated ball screw mounts, the first ever to be made this way, coupled with 15mm HGH type linear rails, and an Anti-Twist mechanism built in gives you the most rigid CNC kit in its class right out of the box.


Comprising speed, rigidity and flexibility in a tough easy to build  platform. The BlackBee CNC kit is designed to meet the ever-growing demands of the maker, enthusiast and small business that strive to create, share and innovate.


Small business small budget.. right?.. Not a problem with this kit, set at a price to encourage the professional hobby maker and small business to purchase. We offer this kit as a production machine, professional capacity built in.


Use 247 to enhance your business. Machine harder, machine deeper, machine faster.

Dimensions available:

1000x1000 (BB1010) Cut area, X 800. Y 800

1000x1500 (BB1015) Cut area, X 800, Y 1300

1500x1000 (BB1510) Cut area, X 1300, Y 800

1500x1500 (BB1515) Cut area, X 1300, Y 1300

1000x3000 (BB1030) Belt or Rack Drive option, Cut area TBA

1500x3000 (BB1530) Belt or Rack Drive option, Cut aread TBA

The dimensions are based on the available C-Beam extrusions from UK / EU suppliers and Openbuilds in the USA.

Rack is Mod1 type, direct drive or optional reducer.


Prices are not fixed at this time due to the ever fluctuating shipping worldwide caused by Covid which is why we ask you to contact us with details of your inquiry.


Once we have a stable shipping cost environment we will announce prices. We hope this to be around end of April to beginning of May

Features / Benefits

Benefits are shown below but not limited to:


1. Option of 12mm ball screw or lead screw

2. Elimination of X axis twist, vital if you are machining regularly (no upgrade other kit addresses this)

3. Better accuracy all round than comparable openbuild kits

4. Smoother drive and smoother motion with linear rails

5. Easier to build than the wheel type motion

6. Rigidity built in, on every axis there is no need to upgrade further.

7. Thicker, better lead nuts, or ball nuts

8. You can machine harder, faster and deeper with this kit

9. Production machining times are much shorter

10. Larger tool bits can be used for clearance areas

11. Keeps the original C-Beam extrusions

12. Use more of your Z gantry

13. Easier maintenance

14. No need to regularly check wheels, bearings and postion of wheels!

15. Rigidity plates bolt to the Y axis V-beams, preventing sway from side to side when machining in X direction, again no other upgrade kit addresses this issue.

16. Dedicated lead nut & ball screw mounts to enhance rigidity


Mechanical kit Consists of:


Aluminium Extrusion 1500mm, 1000mm, or 350mm, 12mm ball screw, length to suit extrusion, machined to fit, ball nut & ball mount, Motor end plate, non motor end plate, Stepper motor spacers, thrust bearings (V1), shims

  • 3 of 15mm HGH type linear rail motion actuators 1000mm (or 1500mm), 12mm ball screws and ball screw mounts

  • 1 of 15mm HGH type rail motion actuators 250mm, 12mm ball screws and ball screw mounts

  • Anti-Twist Tall Y gantry plates

  • Extra C-Beam for Anti-Twist, eliminates twist on the X axis completely

  • Taller End plates to allow full use of 250mm Z (normal use is around 50mm travel only)

  • X/Z Gantry linear motion drive

  • Complete base frame to support spoil board (not including spoil board), with 4 of rigidity plates for Y c-beams (stops the Y c-beams moving in or out, attaches to base to enhance rigidity)

  • Nema 23 motor mounts

  • Corner brackets to secure all extrusions in place

  • All hardware (bolts, nuts, washers etc) to assemble for all above

  • Note Stepper motor coupling are not included because we don't know which type of stepper motor you will use.


Electronics optional

Spindle Not included

Some comparisons


Comparison between MGN15 and HGH15 type rails, for those considering which to go for as part of a WorkBee upgrade.

Classification of MGN type rails.

Note the prolific use of the words, tiny, miniature and so on for the MGx type sets...

The MGx were developed for laboratory use, in runners, PCB insertion, drawers and so on, not CNC kits!


Main Applications for MGx type linear rails

1. Miniature devices

2. Medical equipment

3. IC manufacturing equipment

4. Small X-Y table such as PCB insert

Also, for visual, look here:

There is a very clear difference. Consider which would break first when subject to high CNC force.
