Mechanical Assembly Instructions
About the WorkBee 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 WorkBee 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 Hardware WorkBee V3 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 sales@makerstore.com.au
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 | WorkBee 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 | WorkBee V3 Y-Axis Plate | PLATE-WBV3-Y | 1 |
| 2 | WorkBee 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 |

| 6 | Metric Aluminium Spacers – 9mm | SHIM-SPAC-9MM | 3 |
| 7 | Precision Shim – 10x5x1mm | SHIM-PREC-1051 | 3 |
| 8 | Nylon Insert Hex Locknut – 5mm | HARD-NUT-LOCK-5MM | 3 |
| 9 | Nylon Insert Hex Locknut – 8mm | HARD-NUT-LOCK-8MM | 4 |
| 10 | M8 Round Spacers – 6mm | SHIM-SPAC-81-13-6-1PC | 8 |
| 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 |

| 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 |

| 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.

1.2.6 Y Wheels & Y-Plate-Inner
| Item Number | Description | SKU | Quantity |
| 1 | WorkBee V3 Y-Axis Plate | PLATE-WBV3-Y | 1 |
| 2 | WorkBee 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 |
| 5 | Precision Shim – 10x5x1mm | SHIM-PREC-1051 | 6 |
| 6 | Nylon Insert Hex Locknut – 5mm | HARD-NUT-LOCK-5MM | 3 |
| 7 | Nylon Insert Hex Locknut – 8mm | HARD-NUT-LOCK-8MM | 4 |
| 8 | Eccentric Spacers – 8mm Hex – 6mm Height | SHIM-ECCENTRIC-8-6 | 6 |

| 11 | M8 Round Spacers – 9mm | SHIM-SPAC-81-13-9-1PC | 4 |
| 12 | Solid V Wheel Assembly – 5mm | Solid V Wheel Assembly – 8mm | 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 | 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.
1.2.11 Completed Axis
Repeat this chapter to assemble the other Y-Axis actuator. You should have two actuators which are a 'mirror' of each other.

| Item Number | Description | SKU | Quantity |
| 1 | WorkBee 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 | 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’.

Step 1: Insert the Lead Screw through the Y-Axis Plate and slide a 688Z Bearing and 8mm Lock Collar over the Lead Screw.
Step 2: Thread the ACME-Lead-Screw through the both of the Nut Blocks.
Step 3: With the ACME-Lead-Screws now in position, tighten the screws on the nut blocks that were left loose in step 2.1.2 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.
Step 4: On the other end of the Axis Slide a 8mm Lock Collar and a 688Z Bearing over the Lead Screw and then push the Lead Screw through the other end of the Y-Axis Plate so it is protruding out.
Tip: At this stage don’t tighten the set screws on the 8mm Lock Collars.
