QueenBee XYZ Full 3 axis Upgrade Kit (suits SharpCNC / Workbee)


We have plate sets in stock ready to go!


This SharpCNC / Workbee Profile rail upgrade kit was designed in-house at CNC3D by our engineering team to improve the accuracy even further over the standard design increasing the rigidity on all axes and almost completely eliminate any chatter while milling smooth materials such as acrylic, aluminium and other metals such as brass.


This upgrade is recommended for users who want a smoother finish and to increase the feeds and speeds on their machine for shorter cut times.


Included with this kit:

  • Plate set for X&Z OR a full XYZ upgrade with 50mm Z height work increase.
  • Optional profile rails and bearing blocks to suit your upgrade.
  • Additional Z axis style delrin nut block for X axis screw drive setups.
  • New set of limit switch mounts for X & Z.
  • Precision mini shims for spacing your delrin nuts


Key Features

  • The Z axis has it's V-wheels replaced with precision MGN15 profile rails
  • The X axis has it's V-wheels replaced with precision HGR15 Profile rails across the gantry.
  • This kit does not decrease the overall travel on each axis over the standard with the X&Z upgrade.
  • Superior rigidity on the X & Z axis especially over longer gantry lengths.
  • The ability to safely increase feeds, speeds and depths of cut. 
  • The upgrade kit supports both screw driven SharpCNC / Workbee CNC's on the X & Z axis.


**This kit makes your WorkBee / SharpCNC rigid enough to easily accept a 2.2kw air cooled or water cooled spindle.



Our full XYZ kit does NOT support a belt driven Y axis, it must be converted to screw drive to work. Also, with the Y axis upgrade it decreases your overall X axis travel by approximately 50mm. Please be aware you WILL lose travel with the extra Y axis. 


The Full XYZ QueenBee kit also does not directly support having your spoilboard supports mounted vertically, this however can be made to work by manually cutting the 2040 extrusions that slot between the side C beams. If you are not comfortable cutting these accurately we recommend sticking to an X & Z upgrade only or mounting your spoilboard supports horizontally. 


You will be required to reuse existing parts from your original kit and to source some extra nuts and bolts to complete this upgrade kit, We do not supply any extra nuts, bolts or T nuts with these units as generally they can be sourced locally quite easily.




For optimal perfomance, we recommend cleaning the existing factory machine oil off thoroughly and applying fresh machine oil or grease. To extend the life of these rails we recommend ensuring there is adequate oil/grease on the rails.


Please Note: Due to their size, HGH15 CA & CW bearing blocks do not have a grease nipple for easy lubrication so please ensure that you periodically apply fresh machine oil or grease to the rails to keep these rails performing as expected year after year.

    What the kit includes

    • QueenBee Plate set (either X&Z or XYZ depending on order)
    • HGR15 rails for X & Y (5mm shorter than your ordered size i.e: 1500x1500 machine will have 1495mm profile rails for the X&Y axis)
    • MGN15 profile rails for Z (they will be 245mm)
    • Profile rail bearing blocks to suit your kit
    • Limit switch mount kit to suit upgrade
    • Mini shims (for spacing your Delrin nut blocks if recessed)
    • Delrin nut block (Same as the Z axis for the X axis.)


    What is NOT Included with the kit

    • T-nuts for mounting profile rails 
    • M3 or M4 bolts for mounting your rails
    • Spacers for your delrin nut blocks 
    • Any extra bolts or nuts. 


    Things to know

    This kit does not have a detailed set of instructions provided and requires intermediate - advanced knowledge to assemble this kit. It also requires decent knowledge of your machine and is not recommended for people who are new to their CNC machine. Although, for the mechanically minded this may be a simple upgrade.

    We have a basic set of photo's here that you can refer to for installation. They can be downloaded in .ZIP format HERE


    So what exactly will I need?

    The data here assumes a full XYZ QueenBee kit in 1500x1500mm screw drive the basic extras required are:

    Recommend bolts and numbers for the rails are Socket head bolts.

    • The MGN15 uses M3 12mm bolts and will require approximately 20 bolts. 
    • The HGR15 uses M4 12 - 15mm bolts (rails can vary) and will require approximately 120 bolts. 
    • The MGN15 bearing blocks to our plates require 12mm M3 Bolts
    • The HGR15 bearing blocks require 12mm M4 Bolts.

    You will be reusing a lot of spacers and bolts from your original kit and for a full XYZ QueenBee upgrade you should have enough spacers to complete the kit with some to spare.

    You will require some additional M5 cap head bolts to mount your delrin nuts on the X and Y axis. These measurements can vary but as a general length guide these are the M5 bolt sizes needed:

    Y Delrins: 8 x M5 55mm bolt

    X Delrin: 2 x M5 50mm bolt

    Z Delrin: 2 x M5 35mm bolt

    Limit to extrusion bolts: 3 x M5 10mm bolt

    X-Z plate marriage: 4 x M5 20mm bolt

    Eventually we will have a detailed set of instructions for installing our upgrade kit and we will advise on the listing here once available.

    In the meantime, please reach out to us via Facebook, email or via phone for any assistance in assembling your kit.

  • How we ship our Upgrade kits

    All of our plates, limit switch mounts, delrin nut blocks and shims are shipped from our Workshop on the Gold Coast in Australia via DHL.


    Our profile rails and bearing blocks are shipped directly from our Chinese partner factory via TNT express or UPS.


    **Please note: Due to the coronavirus outbreak there are currently large delays in receiving upgrade kits for both the profile rails and plate sets. These delays can be up to 4-6 weeks.
