The Workbee is a robust CNC router platform.   The QueenBee  Pro is a complete redesign of the WorkBee with the latest performance enhancements designed to improve accuracy, reliability, and capacity.  It is made entirely of extruded aluminum sections with good strength and rigidity, enhanced over the WorkBee design with added extrusions for rigidity, thicker plates for increased strength, and the replacement of all the polycarbonate wheels with high precision linear rails and bearing carriages. A redesigned  base with front and back full width legs and enhanced support provides stability, and C-Beam extrusions form the axis tracks. 

The kits include all mechanical parts needed for the machine, including enhanced torque 1.9 Nm NEMA 23 motors. The machine also incorporates the Tingle Tensioning system, a method for keeping the lead screws in tension, virtually eliminating lead screw whip at high speeds.

The X-Z axis carriage has 2 linear rails with 4 bearing carriages each to support the X and Z axes.  These linear rails replace the outdated wheel system of all previous OB designs.  Not only are they more accurate, with less play, but they are smoother and nearly frictionless.  The hardened steel rails are bolted to the extrusions using dozens of small screws to distribute the load.  These rails add a significant amount of stiffness to the extrusions.  Additionally an extra extrusion is bolted to the back of the X axis c-beam rail to increase stiffness even more.

The Y axis carriages are based on thicker 10mm plates, with 4 linear bearing carriages riding on 2 steel rails per side.  This dramatically increases strength, along with additional extrusion inserts in the Y axis c-beam for even more stiffness.  The Y carriage plates have the X beam mounting holes moved back to give the machine more useable machinable area. 

The Z-Axis C-Beam extrusion is 250mm in length, with a travel of nearly 140mm. The Z axis is supported by its own 4 carriage linear rail system.  The Z-Axis actuator is lead screw driven by a top mounted stepper motor.  A 71mm heavy router mount is an option to use a Bosch Colt or a Dewalt Router.  A 65mm router mount is also available to mount Makita routers and some DC spindles.   An 80mm mount is available for 1.5 and 2.5 Kw VFD spindles as well.  Double router mounts can also be accommodated for extra strength.

An MDF spoil board is mounted in the bottom of the frame. (Not included). The spoil board is bolted to the frame around the perimeter to enhance strength and rigidity.   

  • Bed area Sizes available: 1000x1000mm
  • Active area 1000x1000mm – Approx 840x755x140mm
  • Screw drive  with Tingle Tensioning System on X,Y axes
  • includes Enhanced 265 Oz-in NEMA 23 motors 
  • All mechanical parts included
  • Electronics package not included

These Chinese kits are just as good quality as the OB kits.  They do not include wiring kits, cable chain, and some other minor parts like bed mounting hardware and router mount.   The OB wiring kit is set up to connect to the Black Box controller, it is not really compatible with other controllers.  A full OB kit with wiring, homing, power supply, Black Box, and motors is available.

Fully Assembled and Tested  

3D Tech has its own integrated electronics package that we use with all fully assembled machines.  It mounts directly on the back of the X axis to minimize wiring and to protect the electronics.  It is much more comprehensive than the OpenBuilds Black Box system, and is much more robust as well.  It is capable of adding a fully electronic Homing/Limit switch system which is much more reliable and accurate than the OB micro switch homing.  We use separate stepper drivers, and custom printed circuit boards for more reliability.  Unlike the BB system, the control USB port is completely optically isolated from the  machine motor electronics and all control inputs and outputs.  This ensures that your laptop will survive a catastrophic motor controller failure, unlike the OB BB.  It also uses individual motor drivers that can be replaced for around $50, unlike the BB which you would need to purchase a whole new $275 module if something fails.  Our system also has much better motor current control, optically isolated inputs and outputs for switches and relays, and an E-stop which the OB BB does not.
