About the Maker Store Work-B CNC V3
The first WorkBee CNC model was originally designed by Ryan Lock of Ooznest UK. It was a strong, accurate and easy to assemble CNC machine. This new Maker Store Work-B CNC Version 3 is the Maker Hardware kit based on the popular WorkBee CNC Machine design. This new Version 3 model is heavily modified to achieve better results. It is important to note that the new upgrade is VERY different to other manufacturer’s models. The Maker Store Work-B has two interchangeable transmission systems allowing for a high level of customisation as well as axis compatible with up to 3m in length, allowing for full timber sheets to be worked on!
Pre-Assembly Notes
We recommend that you read through the whole assembly guide before beginning the build, as this enables you to get a rough idea of how it all goes together. Before starting each step make sure you have studied the drawings and fully understand the instructions.
When attaching parts, if a part is requiring significant force to attach, stop, take it off, re-read the instructions and try again. Do not over tighten screws as you may strip the thread or head.
How to use this manual
Follow the Chapter Index below to go directly to the chapter you require. Start by assembling your Y-Axis. After the Y-Axis is assembled you can assemble your X-Axis. When both the Y-Axis and X-Axis are assembled you can assemble your Z-Axis and the finally your Spoiler Board.
Make sure you are referring to the chapter that fits your build. If you have any questions regarding the build please contact us at [email protected]

1.1 Y-Axis Lead Screw
1.1.1 Wheel Assembly
Item Number | Description | SKU | Quantity |
1 | Solid V Wheel | WHEEL-SOLIDV | 1 |
2 | 6882RS Bearing | BEAR-6882RS | 2 |
3 | 8mm Shim | SHIM-PREC-1281 | 1 |
4 | 5mm Shim | SHIM-PREC-1051 | 1 |
5 | 6252RS Bearing | BEAR-6252RS | 2 |
Step 1: Assemble the Solid V Wheel as per the drawing. Ensure you only use 1 Precision Shim between the two Bearings.
Step 2: Repeat this for all the remaining Solid V Wheels
Tip: Seperate the 8mm bore and the 5mm bore bearings so to not incorrectly assemble a wheel with 2 different types of bearings.
1.1.2 ACME Nut Blocks
Item Number | Description | SKU | Quantity |
1 | Work-B V3 Y-Axis Plate | PLATE-WBV3-Y | 1 |
2 | M5 Cap Head Screw – 25mm | SCREWS-M5-CAP-25-1 | 4 |
3 | Precision Shim – 10x5x1mm | SHIM-PREC-1051 | 4 |

5 | 8mm ACME Nut Block | HARD-ACME-8-BLOCK | 2 |
6 | Nylon Insert Hex Locknut – 5mm | HARD-NUT-LOCK-5MM | 2 |
Step 1: Attach 2x ACME-Nut-Block to the Y-Plate using 4x M5-Cap-Head-Screws-25mm & 4x M5-Nylon-Nuts. On each screw, in-between the head of the screw and the Y-Plate, there should be a Precision-Shim. In between the Y-Plate and the ACME-Nut-Block there should be a 3mm Spacer. Only loosely tighten these screws so the ACME-Nut-Blocks can still move side to side.
Step 2: Ensure the recess on the Y-Plate for the 688ZZ Bearing to seat in is on the same side as ACME-Nut-Blocks. The recess is labelled as “A” on the drawing.
Tip: The Maker Hardware Logo is the outer face of the place.
1.1.3 Y Wheels & Y-Plate-Inner
Item Number | Description | SKU | Quantity |
1 | Work-B V3 Y-Axis Plate | PLATE-WBV3-Y | 1 |
2 | Work-B V3 Y-Axis Inner | PLATE-WBV3-Y-INNER | 1 |
3 | M5 Cap Screws – 60mm | SCREWS-M5-CAP-60-1 | 3 |
4 | M8 Cap Screws – 60mm | SCREWS-M8-CAP-60-1 | 4 |

11 | M8 Round Spacers – 9mm | SHIM-SPAC-81-13-9-1PC | 4 |
12 | Solid V Wheel Assembly – 5mm | WHEEL-SOLIDV-KIT | 6 |
13 | Solid V Wheel Assembly – 8mm | WHEEL-SOLIDV-KIT-M8 | 8 |
Step 1: First attach the bottom right wheel set – insert a M5 Cap Screws – 60mm screw through the Y-Plate-Assembly from the back. On to this screw, add an Eccentric-Spacer-6mm, Solid-V-Wheel-M5-Assembly, Metric Aluminium Spacers – 9mm, Solid-V-Wheel-M5-Assembly, and a Eccentric-Spacer-6mm in this order. Next, add a Y-Plate-Inner onto the top of this assemblage, add a Precision Shim – 10x5x1mm onto the screw and then slightly thread on a M5-Nylon-Nut. The rounded portion of the Eccentric-Spacer-6mm should be inserted into the hole on both the Y-Plate-Assembly or Y-Plate-Inner (depending on which side it is on).
Step 2: Attach the top right wheel set – insert a M8 Cap Screws – 60mm screw through the Y-Plate-Assembly from the back. On to this screw, add a M8 Round Spacers – 6mm, Solid-V-Wheel-M8-Assembly, M8 Round Spacers – 9mm, Solid-V-Wheel-M8-Assembly, and a M8 Round Spacers – 6mm in this order. Next, add a Y-Plate-Inner onto the top of this assemblage and then slightly thread on a M8-Nylon-Nut.
Step 3: Once all the wheels are attached the Nylon-Nuts can be tightened down. Ensure that the Solid-V-Wheels can still rotate freely. On the hexagonal portion of the Eccentric-Spacer-6mm, there will be one face that is marked with ‘6mm’. Using a spanner, adjust each Eccentric-Spacer-6mm so that this face is facing downwards. Doing this maximises the gap between the top and bottom row of wheels.
Step 4: Run any piece of C-Beam extrusion in between the two rows of wheels. Initially, the C-Beam will wobble between the wheels. Turn the assembly upside down so the C-Beam is sitting on the top row of wheels (with M8 Aluminium Spacers). Starting with an outside pair of wheels, adjust both Eccentric-Spacer-6mms down onto the C-Beam Extrusion until there is a small amount of friction between both wheels and the C-Beam Extrusion. When adjusting the pair of Eccentric-Spacer-6mms ideally they should be adjusted identically. However, sometimes one will need to be adjusted slightly more than the other to get both wheels engaged with the C-Beam extrusion. Repeat this for the other outside pair of wheels, and then again for the middle pair.
Step 5: Slide the C-Beam extrusion back and forth through the wheels. This should require a small amount of force, and all wheels should spin as it rolls. Also check there is no wobbling of the extrusion. Once happy, double check the tightness of the Nylon-Nuts.
Tip: The Maker Hardware Logo on the Y-Axis-Inner-Plate should be facing outwards. It can be easier to lay the Y-Axis-Plate down and insert all the screws through the holes, then you can add all the other components onto the screws.
Note: Not all wheels may rotate, and some may rotate freely and seem loose, this is okay. Generally it takes a few weeks for the wheels to ‘settle in’.
1.1.4 Y-Axis Extrusions
Item Number | Description | SKU | Quantity |
1 | Y-Axis C-Beam | LR-C-S | 1 |
2 | Y-Axis Assembly | 1 |
Step 1: Slide the Y-Axis Assembly onto the C-Beam. This should slide on easily with little resistance or force required.
If there is resistance stop, do not force it or you risk chipping or cracking a wheel on the edge of the extrusion. Make sure all of the eccentric spacer markings are facing downwards so that the top and bottom rows of wheels are spaced the furthest from each other as possible. You can also loosen all the Nylon Lock Nuts on the wheels by 1 turn to help ‘free up’ the rows of wheels.
Step 2: Once the assembly is on the C-Beam extrusion tighten all of the Nylon Lock Nuts.
Step 3: Recheck the bottom Eccentric-Spacer-6mms on the Y-Gantry-Assembly to make sure they are touching the rail and that there is no wobble.
Note: Not all wheels may rotate, and some may rotate freely and seem loose, this is okay. Generally it takes a few weeks for the wheels to ‘settle in’.
1.1.5 Preparing T-Nuts
Item Number | Description | SKU | Quantity |
1 | Y-Axis Assembly | 1 | |
2 | Tee nuts – M5 | HARD-TNUT-M5-1 | 4 |
Step 1: Insert 2 T-Nuts into both of the bottom channels of the Y-Axis C-Beam. We will use these later in this chapter.
Important: Ensure the flat side of the T-Nut is facing outwards.
1.1.6 End Plates
Item Number | Description | SKU | Quantity |
1 | Y-Axis C-Beam | LR-C-S | 1 |
2 | C-Beam End Mount | PLATE-C-END | 1 |
3 | M5 Cap Screws – 20mm | SCREWS-M5-CAP-20-1 | 4 |
Choose which end of your machine you want your motors to be mounted to. We recommend the back of the machine.
Step 1: Using 4x M5 Cap Screws – 20mm Screws secure the C-Beam End Mount to the C-Beam.
Note: The Recess for the bearing to seat into should be facing inwards.
Leave the other end of the C-Beam off for now, we will attach this later in this chapter.
1.1.7 ACME Screws and Bearings
Item Number | Description | SKU | Quantity |
1 | Y-Gantry Assembly | 1 | |
2 | Y-Axis ACME Lead Screw | HARD-ACME-8 | 1 |
Step 1: Thread the ACME-Lead-Screw through the both of the Nut Blocks.
Step 2: With the ACME-Lead-Screws now in position, tighten the screws on the nut blocks that were left loose in step 1.1.2 so they have a firm fixing. This will ensure the nut blocks are aligned.
Note: Be careful when tightening the nut block screws that the nut block does not slightly rotate when being tightened. This will cause the lead screw to be slightly out of alignment which may cause motor stalling problems later.
1.1.8 Bearings and Jaw Coupler
Item Number | Description | SKU | Quantity |
1 | C-Beam End Mount | PLATE-C-END | 1 |
2 | Y-Axis ACME Lead Screw | HARD-ACME-8 | 1 |

6 | Lock Collar – 8mm | HARD-COLL-8MM | 1 |
7 | 6.35mm x 8mm Jaw Coupling | HARD-COUP-JAW-635X8 | 1 |
Step 1: Slide an 8mm Lock Collar onto the Lead Screw, then slide a 688Z Bearing onto the Lead Screw.
Step 2: Once the inner bearing and lock collar are on the Lead Screw, insert the Lead Screw through the End Plate so it is protruding out the plate.
Step 3: Insert the Thrust Bearing onto the Lead Screw. Next thread the Tensioning Nut onto the Lead Screw. If you have not already inserted the set screw into the Tensioning Nut do so, but do not tighten the set screw so that it makes contact with the Lead Screw, we will do this later.
Step 4: Place the Jaw Coupler over the Lead Screw, make sure the coupler is pushed as far onto the Lead Screw as it can be. Tighten the Coupler set screws so that it is secured to the Lead Screw.
Tip: You can easily move the Y-Axis Gantry from side to side, this will in turn move the Lead Screw which will allow you to position the Lead Screw so that you can easily insert the inner bearings and outer bearings.

12 | Solid V Wheel Assembly – 5mm | Solid V Wheel Assembly – 5mm | 6 |
13 | Solid V Wheel Assembly – 8mm | WHEEL-SOLIDV-KIT-M8 | 8 |
Step 1: First attach the bottom right wheel set – place a Precision Shim – 10x5x1mm over the M5 Cap Screw – 60mm then insert the M5 Cap Screws – 60mm screw through the Y-Plate-Assembly from the back. On to this screw, add an Eccentric-Spacer-6mm, Solid-V-Wheel-M5-Assembly, Metric Aluminium Spacers – 9mm, Solid-V-Wheel-M5-Assembly, and a Eccentric-Spacer-6mm in this order. Next, add a Y-Plate-Inner onto the top of this assemblage, add a Precision Shim – 10x5x1mm onto the screw and then slightly thread on a M5-Nylon-Nut. The rounded portion of the Eccentric-Spacer-6mm should be inserted into the hole on both the Y-Plate-Assembly or Y-Plate-Inner (depending on which side it is on).
Step 2: First attach the top right wheel set – insert a M8 Cap Screws – 60mm screw through the Y-Plate-Assembly from the back. On to this screw, add a M8 Round Spacers – 6mm, Solid-V-Wheel-M8-Assembly, M8 Round Spacers – 9mm, Solid-V-Wheel-M8-Assembly, and a M8 Round Spacers – 6mm in this order. Next, add a Y-Plate-Inner onto the top of this assemblage and then slightly thread on a M8-Nylon-Nut.
Step 3: Once all the wheels are attached the Nylon-Nuts can be tightened down. Ensure that the Solid-V-Wheels can still rotate freely. On the hexagonal portion of the Eccentric-Spacer-6mm, there will be one face that is marked with ‘6mm’. Using a spanner, adjust each Eccentric-Spacer-6mm so that this face is facing downwards. Doing this maximises the gap between the top and bottom row of wheels.
Step 4: Run any piece of C-Beam extrusion in between the two rows of wheels. Initially, the C-Beam will wobble between the wheels. Turn the assembly upside down so the C-Beam is sitting on the top row of wheels (with M8 Aluminium Spacers). Starting with an outside pair of wheels, adjust both Eccentric-Spacer-6mms down onto the C-Beam Extrusion until there is a small amount of friction between both wheels and the C-Beam Extrusion. When adjusting the pair of Eccentric-Spacer-6mms ideally they should be adjusted identically. However, sometimes one will need to be adjusted slightly more than the other to get both wheels engaged with the C-Beam extrusion. Repeat this for the other outside pair of wheels, and then again for the middle pair.
Step 5: Slide the C-Beam extrusion back and forth through the wheels. This should require a small amount of force, and all wheels should spin as it rolls. Also check there is no wobbling of the extrusion. Once happy, double check the tightness of the Nylon-Nuts.
Tip: The Maker Hardware Logo on the Y-Axis-Inner-Plate should be facing outwards. It can be easier to lay the Y-Axis-Plate down and insert all the screws through the holes, then you can add all the other components onto the screws.
Note: Not all wheels may rotate, and some may rotate freely and seem loose, this is okay. Generally it takes a few weeks for the wheels to ‘settle in’.
1.2.7 Gear Racks
Item Number | Description | SKU | Quantity |
1 | Y-Axis C-Beam | LR-C-S | 1 |
2 | Sliding T-Nut | TNUT-M5-SLIDING | 1 |
3 | Module 1.0 Gear Rack – Internal | GEAR-M1-INT-500-D | 1 |
Insert the Internal Gear Racks into the C-Beam. You may need to cut the last Gear Rack so it does not protrude out of the C-Beam too far. The ideal length of the Gear Rack is approximately 2mm protruding out of each end of the C-Beam. For now do not cut the Gear Rack to size until later in this chapter.
1.2.8 Preparing T-Nuts
Item Number | Description | SKU | Quantity |
1 | Y-Axis Assembly | 1 | |
2 | Tee nuts – M5 | HARD-TNUT-M5-1 | 4 |
Step 1: Insert 2 T-Nuts into both of the bottom channels of the Y-Axis C-Beam. We will use these later in this chapter.
Important: Ensure the flat side of the T-Nut is facing outwards.
1.2.9 Loading Y-Carriage
Item Number | Description | SKU | Quantity |
1 | Y-Axis C-Beam | LR-C-S | 1 |
2 | Y-Axis Assembly | 1 |
Step 1: Slide the Y-Axis Assembly onto the C-Beam. This should slide on easily with little resistance or force required.
If there is resistance stop, do not force it or you risk chipping or cracking a wheel on the edge of the extrusion. Make sure all of the eccentric spacer markings are facing downwards so that the top and bottom rows of wheels are spaced the furthest from each other as possible. You can also loosen all the Nylon Lock Nuts on the wheels by 1 turn to help ‘free up’ the rows of wheels.
Step 2: Once the assembly is on the C-Beam make sure the Pinion Gear is centred over the Gear Rack, if it is not then loosen the Pinion Gear and reposition it on the motor shaft so that it will line up centre of the Gear Rack.
Step 3: Tighten the screw that has the spring installed until the Pinion Gear is sitting hard against the Gear Rack.
IMPORTANT: The right amount of tightening in the M5 Nylon Hex Locknut and spring loaded screw is when the motor plate becomes hard against the Gear Rack so that it is fully seated into the teeth of the Gear Rack. This means that this nut should not be over-tight or under tight.
Step 4: At this point remove the Y-Axis assembly from the C-Beam and tighten the lock nuts that we left slightly loose in steps 1.2.2 (there are 3 to tighten). Once these are tightened you can slide the assembly back onto the C-Beam.
Step 5: Once the assembly is on the C-Beam extrusion recheck the bottom Eccentric-Spacer-6mms on the Y-Gantry-Assembly to make sure they are touching the rail and that there is no wobble.
Note: Not all wheels may rotate, and some may rotate freely and seem loose, this is okay. Generally it takes a few weeks for the wheels to ‘settle in’. If you have not tightened all Nylon-Nuts at this point then do so.
1.2.10 End Plates
Item Number | Description | SKU | Quantity |
1 | Y-Axis C-Beam | LR-C-S | 1 |
2 | C-Beam End Mount | PLATE-C-END | 1 |
3 | M5 Cap Screws – 20mm | SCREWS-M5-CAP-20-1 | 4 |
Step 1: Using 4x M5 Cap Screws – 20mm secure the C-Beam End Mount to the C-Beam.
Note: The Recess for the bearing to seat into should be facing inwards.
Repeat for the other end of the C-Beam.
The Gear Racks will squeeze together. If the Gear Racks are protruding too much you may need to cut off a small amount. The important feature is the Gear Racks are slightly longer than the C-Beam, this way they will be placed under tension when the plates are secured to each end.

Item Number | Description | SKU | Quantity |
1 | Work-B V3 Y-Axis Plate | PLATE-WBV3-Y | 1 |
2 | M5 Cap Screw – 30mm | SCREWS-M5-CAP-30-1 | 3 |
3 | M8 Cap Screw – 30mm | SCREWS-M8-CAP-30-1 | 4 |
4 | Precision Shim – 10x5x1mm | SHIM-PREC-1051 | 6 |
5 | Eccentric Spacers – 8mm Hex – 6mm Height | SHIM-ECCENTRIC-8-6 | 3 |
6 | M8 Round Spacers – 6mm | SHIM-SPAC-81-13-6-1PC | 4 |
7 | Nylon Insert Hex Locknut – 5mm | HARD-NUT-LOCK-5MM | 3 |
8 | Nylon Insert Hex Locknut – 8mm | HARD-NUT-LOCK-8MM | 4 |
9 | Solid V Wheel Assembly – 5mm | WHEEL-SOLIDV-KIT-M5 | 3 |
10 | Solid V Wheel Assembly – 8mm | WHEEL-SOLIDV-KIT-M8 | 4 |
Step 1: First attach the bottom right wheel set – place a Precision Shim – 10x5x1mm over the M5 Cap Screw – 30mm then insert the M5 Cap Screw – 30mm through the Y-Plate-Assembly from the back. On to this screw, add an Eccentric-Spacer-6mm, Solid-V-Wheel-M5-Assembly, then slightly thread on a M5-Nylon-Nut. The rounded portion of the Eccentric-Spacer-6mm should be inserted into the hole on both the Y-Plate-Assembly.
Step 2: Attach the top right wheel set – insert a M8 Cap Screw – 30mm through the Y-Plate-Assembly from the back. On to this screw, add a M8 Round Spacers – 6mm, Solid-V-Wheel-M8-Assembly, then slightly thread on a M8-Nylon-Nut.
Step 3: Once all the wheels are attached the Nylon-Nuts can be tightened down. Ensure that the Solid-V-Wheels can still rotate freely. On the hexagonal portion of the Eccentric-Spacer-6mm, there will be one face that is marked with ‘6mm’. Using a spanner, adjust each Eccentric-Spacer-6mm so that this face is facing downwards. Doing this maximises the gap between the top and bottom row of wheels.
Step 4: Run any piece of C-Beam extrusion in between the two rows of wheels. Initially, the C-Beam will wobble between the wheels. Turn the assembly upside down so the C-Beam is sitting on the top row of wheels (with M8 Aluminium Spacers). Starting with an outside wheel, adjust both Eccentric-Spacer-6mms down onto the C-Beam Extrusion until there is a small amount of friction between the wheels and the C-Beam Extrusion. Repeat this for the other outside wheel, and then again for the middle wheel.
Step 5: Slide the C-Beam extrusion back and forth through the wheels. This should require a small amount of force, and all wheels should spin as it rolls. Also check there is no wobbling of the extrusion. Once happy, double check the tightness of the Nylon-Nuts.
Tip: The Maker Hardware Logo on the Y-Axis-Inner-Plate should be facing outwards. It can be easier to lay the Y-Axis-Plate down and insert all the screws through the holes, then you can add all the other components onto the screws.
Note: Not all wheels may rotate, and some may rotate freely and seem loose, this is okay. Generally it takes a few weeks for the wheels to ‘settle in’.
1.3.7 Gear Racks
Item Number | Description | SKU | Quantity |
1 | Y-Axis C-Beam | LR-C-S | 1 |
2 | Sliding T-Nut | TNUT-M5-SLIDING | 1 |
3 | Module 1.0 Gear Rack – Internal | GEAR-M1-INT-500-D | 1 |
Insert the Internal Gear Racks into the C-Beam. You may need to cut the last Gear Rack so it does not protrude out of the C-Beam too far. The ideal length of the Gear Rack is approximately 2mm protruding out of each end of the C-Beam. For now do not cut the Gear Rack to size until later in this chapter.
1.3.8 Preparing T-Nuts
Item Number | Description | SKU | Quantity |
1 | Y-Axis Assembly | 1 | |
2 | Tee nuts – M5 | HARD-TNUT-M5-1 | 7 |
Step 1: Insert 2 T-Nuts into both of the bottom channels of the Y-Axis C-Beam and 3 T-Nuts into the bottom channel of the inwards facing side of the C-Beam (the 80mm face). We will use these later in this chapter.
Important: Ensure the flat side of the T-Nut is facing outwards.
1.3.9 Loading Y-Carriage
Item Number | Description | SKU | Quantity |
1 | Y-Axis C-Beam | LR-C-S | 1 |
2 | Y-Axis Assembly | 1 |
Step 1: Slide the Y-Axis Assembly onto the C-Beam. This should slide on easily with little resistance or force required.
If there is resistance stop, do not force it or you risk chipping or cracking a wheel on the edge of the extrusion. Make sure all of the eccentric spacer markings are facing downwards so that the top and bottom rows of wheels are spaced the furthest from each other as possible. You can also loosen all the Nylon Lock Nuts on the wheels by 1 turn to help ‘free up’ the wheels.
Step 2: Once the assembly is on the C-Beam make sure the Pinion Gear is centred over the Gear Rack, if it is not then loosen the Pinion Gear and reposition it on the motor shaft so that it will line up centre of the Gear Rack.
Step 3: Tighten the screw that has the spring installed until the Pinion Gear is sitting hard against the Gear Rack.
IMPORTANT: The right amount of tightening in the M5 Nylon Hex Locknut and spring loaded screw is when the motor plate becomes hard against the Gear Rack so that it is fully seated into the teeth of the Gear Rack. This means that this nut should not be over-tight or under-tight.
Step 4: At this point remove the Y-Axis assembly from the C-Beam and tighten the lock nuts that we left slightly loose in steps 1.3.2 (there are 3 to tighten). Once these are tightened you can slide the assembly back onto the C-Beam.
Step 5: Once the assembly is on the C-Beam extrusion recheck the bottom Eccentric-Spacer-6mms on the Y-Gantry-Assembly to make sure they are touching the rail and that there is no wobble.
Note: Not all wheels may rotate, and some may rotate freely and seem loose, this is okay. Generally it takes a few weeks for the wheels to ‘settle in’. If you have not tightened all Nylon-Nuts at this point then do so.
1.3.10 End Plates
Item Number | Description | SKU | Quantity |
1 | Y-Axis C-Beam | LR-C-S | 1 |
2 | C-Beam End Mount | PLATE-C-END | 1 |
3 | M5 Cap Screws – 20mm | SCREWS-M5-CAP-20-1 | 4 |
Step 1: Using 4x M5 Cap Screws – 20mm secure the C-Beam End Mount to the C-Beam.
Note: The Recess for the bearing to seat into should be facing inwards.
Repeat for the other end of the C-Beam.
The Gear Racks will squeeze together. If the Gear Racks are protruding too much you may need to cut off a small amount. The important feature is the Gear Racks are slightly longer than the C-Beam, this way they will be placed under tension when the plates are secured to each end.
1.3.11 Completed Axis
Repeat this chapter to assemble the other Y-Axis actuator. You should have two actuators which are a ‘mirror’ of each other.

12 | Solid V Wheel Assembly – 8mm | WHEEL-SOLIDV-KIT-M8 | 6 |
13 | Solid V Wheel Assembly – 5mm | WHEEL-SOLIDV-KIT | 6 |
Step 1: First attach the bottom right wheel set – insert a M5 Cap Screw – 65mm through the X-Plate-Front. On to this screw, add an Eccentric-Spacer-6mm, Solid-V-Wheel-M5-Assembly, Metric Aluminium Spacer – 9mm, Solid-V-Wheel-M5-Assembly, and a Eccentric-Spacer-6mm in this order. Next, add a X-Plate-Back onto the top of this assemblage, add a Precision Shim onto the screw and then slightly thread on a M5-Nylon-Nut. The rounded portion of the Eccentric-Spacer-6mm should be inserted into the hole on both the X-Plate-Back or X-Plate-Front (depending on which side it is on).
Step 2: Attach the top right wheel set – insert a M8 Cap Screw – 65mm through the X-Plate-Front. On to this screw, add a M8 Round Spacer – 6mm, Solid-V-Wheel-M8-Assembly, M8 Round Spacer – 9mm, Solid-V-Wheel-M8-Assembly, and a M8 Round Spacer – 6mm in this order. Next, add a X-Plate-Back onto the top of this assemblage and then slightly thread on a M8-Nylon-Nut.
Step 3: Once all the wheels are attached the Nylon-Nuts can be tightened down. Ensure that the Solid-V-Wheels can still rotate freely. On the hexagonal portion of the Eccentric-Spacer-6mm, there will be one face that is marked with ‘6mm’. Using a spanner, adjust each Eccentric-Spacer-6mm so that this face is facing downwards. Doing this maximises the gap between the top and bottom row of wheels.
Step 4: Run any piece of C-Beam extrusion in between the two rows of wheels. Initially, the C-Beam will wobble between the wheels. Turn the assembly upside down so the C-Beam is sitting on the top row of wheels (with M8 Aluminium Spacers). Starting with an outside pair of wheels, adjust both Eccentric-Spacer-6mms down onto the C-Beam Extrusion until there is a small amount of friction between both wheels and the C-Beam Extrusion. When adjusting the pair of Eccentric-Spacer-6mms ideally they should be adjusted identically. However, sometimes one will need to be adjusted slightly more than the other to get both wheels engaged with the C-Beam extrusion. Repeat this for the other outside pair of wheels, and then again for the middle pair.
Step 5: Slide the C-Beam extrusion back and forth through the wheels. This should require a small amount of force, and all wheels should spin as it rolls. Also check there is no wobbling of the extrusion. Once happy, double check the tightness of the Nylon-Nuts.
Tip: It can be easier to lay the X-Plate-Front down and insert all the screws through the holes, then you can add all the other components onto the screws.
Note: Not all wheels may rotate, and some may rotate freely and seem loose, this is okay. Generally it takes a few weeks for the wheels to ‘settle in’.

12 | Solid V Wheel Assembly – 5mm | WHEEL-SOLIDV-KIT-M5 | 6 |
13 | Solid V Wheel Assembly – 8mm | WHEEL-SOLIDV-KIT | 6 |
Step 1: First attach the bottom right wheel set – insert a M5 Cap Screw – 65mm through the X-Plate-Front. On to this screw, add an Eccentric-Spacer-6mm, Solid-V-Wheel-M5-Assembly, Metric Aluminium Spacer – 9mm, Solid-V-Wheel-M5-Assembly, and a Eccentric-Spacer-6mm in this order. Next, add a X-Plate-Back onto the top of this assemblage, add a Precision Shim onto the screw and then slightly thread on a M5-Nylon-Nut. The rounded portion of the Eccentric-Spacer-6mm should be inserted into the hole on both the X-Plate-Back or X-Plate-Front (depending on which side it is on).
Step 2: Attach the top right wheel set – insert a M8 Cap Screw – 65mm screw through the X-Plate-Front. On to this screw, add a M8 Round Spacer – 6mm, Solid-V-Wheel-M8-Assembly, M8 Round Spacer – 9mm, Solid-V-Wheel-M8-Assembly, and a M8 Round Spacer – 6mm in this order. Next, add a X-Plate-Back onto the top of this assemblage and then slightly thread on a M8-Nylon-Nut.
Step 3: Once all the wheels are attached the Nylon-Nuts can be tightened down. Ensure that the Solid-V-Wheels can still rotate freely. On the hexagonal portion of the Eccentric-Spacer-6mm, there will be one face that is marked with ‘6mm’. Using a spanner, adjust each Eccentric-Spacer-6mm so that this face is facing downwards. Doing this maximises the gap between the top and bottom row of wheels.
Step 4: Run any piece of C-Beam extrusion in between the two rows of wheels. Initially, the C-Beam will wobble between the wheels. Turn the assembly upside down so the C-Beam is sitting on the top row of wheels (with M8 Aluminium Spacers). Starting with an outside pair of wheels, adjust both Eccentric-Spacer-6mms down onto the C-Beam Extrusion until there is a small amount of friction between both wheels and the C-Beam Extrusion. When adjusting the pair of Eccentric-Spacer-6mms ideally they should be adjusted identically. However, sometimes one will need to be adjusted slightly more than the other to get both wheels engaged with the C-Beam extrusion. Repeat this for the other outside pair of wheels, and then again for the middle pair.
Step 5: Slide the C-Beam extrusion back and forth through the wheels. This should require a small amount of force, and all wheels should spin as it rolls. Also check there is no wobbling of the extrusion. Once happy, double check the tightness of the Nylon-Nuts.
Tip: It can be easier to lay the X-Plate-Front down and insert all the screws through the holes, then you can add all the other components onto the screws.
Note: Not all wheels may rotate, and some may rotate freely and seem loose, this is okay. Generally it takes a few weeks for the wheels to ‘settle in’.

2.2.9 Loading X-Carriage
Item Number | Description | SKU | Quantity |
1 | X-Axis Assembly | 1 | |
2 | X-Axis C-Beam | LR-C-S | 1 |
Step 1: Slide the X-Axis Assembly onto the C-Beam. This should slide on easily with little resistance or force required.
If there is resistance stop, do not force it or you risk chipping or cracking a wheel on the edge of the extrusion. Make sure all of the eccentric spacer markings are facing downwards so that the top and bottom rows of wheels are spaced the furthest from each other as possible. You can also loosen all the Nylon Lock Nuts on the wheels by 1 turn to help ‘free up’ the rows of wheels.
Step 2: Once the assembly is on the C-Beam make sure the Pinion Gear is centred over the Gear Rack, if it is not then loosen the Pinion Gear and reposition it on the motor shaft so that it will line up centre of the Gear Rack.
Step 3: Tighten the screw that has the spring installed until the Pinion Gear is sitting hard against the Gear Rack.
IMPORTANT: The right amount of tightening in the M5 Nylon Hex Locknut and spring loaded screw is when the motor plate becomes hard against the Gear Rack so that it is fully seated into the teeth of the Gear Rack. This means that this nut should not be over-tight or under tight.
Step 4: At this point remove the X-Axis assembly from the C-Beam and tighten the lock nuts that we left slightly loose in steps 2.2.2 (there are 3 to tighten). Once these are tightened you can slide the assembly back onto the C-Beam.
Step 5: Once the assembly is on the C-Beam extrusion recheck the bottom Eccentric-Spacer-6mms on the X-Gantry-Assembly to make sure they are touching the rail and that there is no wobble.
Note: Not all wheels may rotate, and some may rotate freely and seem loose, this is okay. Generally it takes a few weeks for the wheels to ‘settle in’. If you have not tightened all Nylon-Nuts at this point then do so.

Repeat Step 1 and Step 2 for the other end of the extrusion and for the other three extrusions.
Tip: Leave the screw securing the Single L Bracket slightly loose so that the bracket can slide along the extrusion. We will position them correctly later in this chapter.
4.2.4 Attaching Parallel Supports to the Y-Axis
Item Number | Description | SKU | Quantity |
1 | Y-Axis C-Beam | 1 | |
2 | Parallel 2040 Extrusion C-Beam | Parallel 2040 Extrusion C-Beam | 1 |
3 | M5 T-Nut | HARD-TNUT-M5-1 | 1 |
4 | M5 Low Profile Screws – 8mm | SCREWS-M5-LP-8-1 | 1 |
There are three Parallel 2040 Extrusions to secure between the Y-Axis C-Beams. Start with the middle Parallel 2040 Extrusion.
Step 1: Measure between the Front and Back 2040 Extrusions for the middle of each Y-Axis C-Beam and position the Parallel 2040 Extrusion in place. Then measure the middle point between this centre Parallel 2040 Extrusion and the Front/Back 2040 Extrusion and position the other two Parallel 2040 Extrusions in place.
Tip: Use one extrusion, either the Front or the Back 2040 Extrusion, as your datum. Mark all measurements from this datum for maximum accuracy.
Step 2: Using the M5 T-Nuts that we inserted in a previous chapter in Step 1.3.8 attach the L1 Bracket to the Y-Axis C-Beam using a M5 Low Profile Screw – 8mm.
At this point leave both the screws slightly loose so we can finalise the position of the extrusion.
Step 3: Position the Parallel 2040 Extrusion so that it sits evenly under both sides of the Y-Axis C-Beam.
To do this make sure the screw that secures the L1 Bracket to the Parallel 2040 Extrusion is loose so that the bracket can move along this extrusion. Move the entire X-Axis so that it is over the Parallel 2040 Extrusion you are securing, this will ensure both Y-Axis C-Beams are spaced the correct distance apart from each other.
Step 4:Then when the Parallel 2040 Extrusion is under both C-Beams equally you can tighten the brackets in place. Make sure to secure the L1 Brackets before you move the X-Axis again.
Important: The Parallel 2040 Extrusion should sit under the Y-Axis C-Beam approximately 10mm. This ensures the weight of the C-Beam is directly on the 2040 extrusion. The L1 Bracket secures the two extrusions together.
Repeat this step for the other two Parallel 2040 Extrusions.
Move the gantry past each Parallel 2040 Extrusion to ensure the spacing is correct and the gantry is not colliding with the extrusion.
Tip: Because of the size of the machine it can be much easier to get a second person to help you move the other gantry.

For simplification purposes, the CDC mounting process has been divided into two parts:
X-Axis:
Step 1: Line up the CDC Mounting Bracket slots with the X-Axis Plate top holes as shown in the image and insert 2x M5 Low Profile Screws 15mm through slots into the holes.
Step 2: Tighten the above assembly using 2x Nylon Insert Hex Locknut M5.
Step 3: Place 2x Drop In Tee Nut M4 into the groove of the X-Axis 2040 extrusion. Line up one of the CDC End holes with the Tee Nuts.
Step 4: Insert 2x M4 Button Head Screw 8mm into the holes and Tee Nuts and tighten using an Allen Key.
Step 5: Place the other CDC End on the CDC Mounting Bracket and align the holes of the same with slots of the CDC Mounting Bracket, as shown in the image.
Pro Tip: Ensure the CDC is straight in reference to the other attached CDC End. Adjust the mounting position on the CDC Mounting Bracket by using different slots.
Step 6: Insert 2x M4 Button Head Screws 10mm into the CDC End holes through the aligned CDC Mounting Bracket slots.
Step 7: Tighten the above assembly using 2x Nylon Insert Hex Locknut M4.
Y-Axis:
Step 1: Line up the CDC Bracket Mounting Slots with holes of the Y-Axis plate, as shown in the image.
Step 2: Insert 2x M5 Low Profile Screws 8mm into the slots and through the aligned holes.
Step 3: If you are using a separate extrusion for mounting Y-Axis CDC, then follow steps 3 & 4 of X-Axis to mount one of the CDC End or you can directly mount the CDC End to the tabletop where the CNC Machine is mounted.
Step 4: Place the other CDC End onto the Mounting Bracket and line up the CDC Mounting holes with slots of CDC Mounting Bracket, as shown in the image.
Pro Tip: Ensure the CDC is straight in reference to the other attached CDC End. Adjust the mounting position on the CDC Mounting Bracket by using different slots.
Step 5: Insert 2x M4 Button Head Screws 10mm through the same holes and slots of the CDC Mounting Bracket.
Step 6: Tighten the above assembly using 2x Nylon Insert Hex Locknuts M4.

5.2 Limit Switches
There are two types of mechanical limit switches available for the Work-B. The Micro Limit Switch (Type A) and the CMV103C Long Arm/CMV104D Short Arm (Type B). See images below for reference.


5.2.1 Limit Switch Assembly
To assemble the CMV103C/104D Limit Switch, use the BoM and follow the steps below:
Step 1. Insert 2x 12mm M3 Cap Head Bolts (3) into the two holes of the CMV103C Limit Switch (1)
Step 2. Referring to figure 4, line up the appropriate threaded holes of the Limit Switch Plate V2 (2) with the 12mm M3 Cap Head Bolts (3) so that the limit switch lever hangs off the front of the plate.
Step 3. Finally, screw in the 12mm M3 Cap Head Bolts (3) into the threaded holes of the Limit Switch Plate V2 (2).
It is possible to invert the limit switch for right-side sensing.
To mount the limit switch and plate to your machine:
Step 4. Line up the limit switch arm with a suitable flat surface to trigger the limit switch lever on your machine. This can be a gantry plate, bearing or a V-Wheel.
Step 5. Insert the Spring Loaded Tee Nuts (5) into a V-Slot channel (Figure 6) and then line up the slot of the limit switch plates with the Spring Loaded Tee Nuts (Figure 7). Use an Allen key to fasten the M5-Button Head Screws-8mm (4) into the Tee Nuts through the plate to secure the micro limit switch assembly (Figure 8).
This completes the assembly of the CMV103C/104D limit switch kit.
To assemble the Micro Limit Switch, use the BoM and follow the steps below:
Step 1. Insert the 2x M3-Cap Head Screw-10mm (1) through the Limit Switch Plate (5) so that the screws are lined up (horizontally or vertically). Configuration is dependant on how you plan to mount the limit switch plate.
Step 2. Line up both holes of the Micro Limit Switch (4) with the 2x M3-Cap Head Screw-10mm (1), secure the Micro Limit Switch to the plate.
Note: Some force may be needed if the Micro Limit Switch has not been threaded beforehand.
Note: Do not over tighten!
Step 3. To mount the Plate and Micro Limit switch to a machine or V-slot extrusion, insert the M5-Button Head Screw-8mm (3) through the larger slot in the Limit Switch Plate (5) and the Slot Washer – 15x5x2mm (6), then secure by screwing the Spring Loaded Tee Nut (2) onto the M5-Button Head Screw-8mm loosely. See figure 7 for reference.
Step 4. Line up the red limit switch with a suitable flat surface on your machine, such as a gantry plate, bearing or even a V-Wheel. Insert the Spring Loaded Tee Nut (2) into a V-Slot channel, then use an Allen key to turn the M5-Button Head Screw-8mm (3) clockwise into the tee nut through the plate to secure the micro limit switch assembly.
Limit switch kits can be placed in any location you can secure it. For our machines we suggest limits and homing to be located on the Front of the Y – axis, Left of the X – axis, and Bottom of the Z – axis.
