¶ Introduction
It is strongly recommended to assemble the toolhead frame on a known flat surface (such as a solid table, work surface or similar). This will ensure that the toolhead is assembled squarely. A non-square toolhead can cause issues with print quality and performance.
¶ Step 1 - Tools for this guide
- The following tools are required for this guide:
- Allen key / hex wrenches in the following sizes: 1.5mm, 2mm, & 2.5mm
- Avoid using ball end hex wrenches where possible as they are more prone to damaging the heads of smaller screws
- Torx driver in the following size: T8
- The following tools are recommended for this guide:
- A pair of small cutters or flush-cutters
¶ Step 2 - Prepare the toolhead side plates and fasteners
- 1x Rat Rig V-Core 4.1 - Toolhead - Left Plate (SKU: HW4337PC)
- 1x Rat Rig V-Core 4.1 - Toolhead - Right Plate (SKU: HW4338PC)

¶ Step 3 - Assemble the toolhead frame - Part 1
- 1x Rat Rig V-Core 4.1 - Toolhead - Left Plate
- 2x M3x6 Countersink Screw
- Insert an M3x6 Countersink Screw into each of the two marked positions on the left toolhead plate
- 2x Hex Standoff - Steel - M3x42mm
- Install a hex standoff onto each of the two M3x6 Countersink Screws and then partially tighten them, just enough to keep the assembly together. They will be fully tightened in a later step
¶ Step 4 - Assemble the toolhead frame - Part 2

¶ Step 8 - Square the toolhead frame
- Place the toolhead frame on a known flat surface such as a solid table, work surface, or similar
- Loosen all eight M3x6 Countersink Screws by half of a turn. The toolhead frame assembly should be loose and wobble
- Apply a gentle downward force to the toolhead top plate in the marked area
- Whilst continuing to apply downwards force, partially fasten the upper four M3x6 Countersink Screws which secure the top plate to the assembly
- Whilst continuing to apply downwards force, fully tighten the upper four M3x6 Countersink Screws which secure the top plate to the assembly
- Partially fasten the lower four M3x6 Countersink Screws which secure the hex standoffs to the assembly
- Fully tighten the lower four M3x6 Countersink Screws which secure the hex standoffs to the assembly
- Check that the toolhead assembly does not wobble on the flat surface. If it sits flat and stable, it has been fully squared. If it wobbles, repeat the above instructions until it is stable
¶ Step 9 - Prepare the front printed part and fasteners
- 1x rr_toolhead_vc41_front assembly (SKU: PP000401)
- 3x M3x6 Countersink Screw (SKU: HW3414SC)

- If the holes do not align correctly, follow the next steps to adjust the hotend alignment
¶ Step 14 - Adjust the Rapido 2 hotend alignment - Part 1
- If the cables of the Rapido 2 hotend do not align with the toolhead slot, follow the next steps:
- Phaetus Rapido 2 Plus UHF Hotend
- Silicone sock
- Pull the silicone sock downwards to remove it from the hotend
- Slightly loosen the M3 Set Screw within the Rapido heatsink
- Do not unscrew the set screw completely or remove it. It only needs to be slightly loose
¶ Step 15 - Adjust the Rapido 2 hotend alignment - Part 2
- Carefully remove all three M2 Cap Head Screws from the Rapido hotend
- The heads on the M2 screws are fragile, make sure to use good quality tools to avoid stripping them
- Carefully rotate the heatsink in either a clockwise, or counter-clockwise direction until the three holes align with the threads in the heatsink
- Do not remove the heatsink from the hotend assembly. Doing so can cause the small heat-break clamp to fall out and get lost, rendering the hotend useless
- Trial and error is required to align the hotend with the toolhead slot. It may require a 120 degree turn, or a 240 degree one, the only way to find out is to test
¶ Step 16 - Adjust the Rapido 2 hotend alignment - Part 3
- Carefully reinstall all three M2 Cap Head Screws into the Rapido hotend
- The heads on the M2 screws are fragile, make sure to use good quality tools to avoid stripping them
- Do not overtighten the M2 screws. Due to their small size, they are fragile and may snap if overtightened
- Carefully tighten the M3 Set Screw within the Rapido heatsink
- Do not overtighten the M3 Set Screw as this can cause permanent damage to the heat-break within the heatsink
- Reinstall the silicone sock onto the end of the hotend by slipping it on and pushing it upwards
- Follow step 13 and try to install the hotend. If the cables are still misaligned, repeat steps 14, 15 and 16 to change the alignment once again

- Connect the 40x28 Part cooling fan to this connector
¶ Step 67 - Connect the toolhead electronics - 40x10 Hotend cooling fan
- Locate the marked connector on the Orbitool O2S Toolboard
- 40x10 Hotend cooling fan connector
- Connect the 40x10 Hotend cooling fan to this connector
¶ Step 68 - Connect the toolhead electronics - Beacon Sensor
- Locate the marked connector on the Orbitool O2S Toolboard
- Beacon Sensor connector
- Connect the Beacon Sensor to this connector
¶ Step 69 - Configure the 40x28 part cooling fan voltage
- Locate the marked jumper pins on the Orbitool O2S Toolboard
- It is important to correctly configure the voltage supplied to the 40x28 part cooling fan. Failure to do so will cause irreparable damage to components
- The 40x28 part cooling fan originally supplied with the V-Core 4.0 kit is a 12V fan. If you are upgrading a V-Core 4.0, then the Orbitool toolboard must be configured to output 12V
- Orbitool O2S Toolboard Jumper
- Install the jumper on the two pins as shown, this will configure the Orbitool O2S Toolboard to output 12V for the 40x28 fan output
¶ Step 70 - Manage the toolhead cables
- There are several points on the toolhead designed to help with cable management:
- Printed cable tie point - Orbitool - Left
- Printed cable tie point - Orbitool - Right
- Use these points to manage the cables and prevent them from wobbling freely. Loose cables can affect the input shaper results, and print quality
