DEFAULT CONFIGURATION

This "Standard Kit" is meant for users who are unsure about which configuration options to choose, and are above all else interested in acquiring a kit as complete as possible, including all necessary electronics, and with proper documentation to guide them from beginning to end. If you're not feeling particularly adventurous, this is the V-Core 3 "walled garden" - this is where we recommend you should stay if you're just starting out and need someone to hold your hand and show you the way! ;)

For full transparency, this is our favorite machine configuration and the one we use on our own print farm.

The default configuration only lets you choose your desired build volume. For each build volume, this is what you are buying when you add this item to your cart:

    WARNING FOR USERS IN COUNTRIES WHICH USE 120V MAINS

    CAUTION: if your country uses 120V mains, please be aware that the Power Supply included in this kit contains a switch which allows it to operate at either 115V or 230V. By default, all units will ship with the switch positioned at 230V, so you will need to flip this switch before using the Power Supply.

     

    NOT INCLUDED

    We're working to get there, but for now, the default configuration is not the same as a turn-key, complete kit. Some items will need to be sourced elsewhere.


  • - Power cord - you will need to source a power cord with a plug, to connect your machine to the wall. We don't supply them since we ship worldwide and different countries use different plug types.

  • - Extra printed parts (LAN/IEC adapter, back-spine/nut/collar for cable routing on the electronics panel) - these cable management parts are non-essential and can be printed later.

  • - IEC/Lan Plug - these are optional, and need to be user sourced.

  • - Cable crimping - you may need a crimping tool to assemble your electronics. 

  • - Optional Electronics panel and enclosing panels - these are meant to be sourced locally by the user, DXF files with size, shape and hole patterns for the panels are provided for this purpose. Using 4mm thick polycarbonate sheets is suggested (CAUTION: thickness above 4mm is not advised as it will interfere with the XY motors).

  • - Fasteners to mount electronics to back panel (8 generic nylon spacers are included for this purpose, though)

  • - Depending on machine size and where you want to install the controller board, extension cables may be needed for the following components: BLTouch, SuperPinda, hotend heater and thermistor, limit switches - these components ship with short cables, and at the moment we do not stock extensions for them. We recommend sourcing the following cables:

  • To extend the cabling of your Bltouch:
    1x 22AWG Cable 5 Conductors 1500mm
    To connect PSU, SSR and board:
    3x 16AWG Cable 2 Conductors 500mm

    V-CORE 3

    The V-Core 3 is a premium DIY kit for a CoreXY 3D Printer with no compromises.

     
     

    This kit is the culmination of Rat Rig's accumulated years of experience designing, producing and distributing DIY 3D Printer kits worldwide. Originally introduced in 2017, the V-Core went through several iterations and multiple variants over time, through a process of continuously seeking user feedback to drive product development. The lessons learned over the years allowed us to understand what works and what doesn't, what features are most valued by users, and what choices ensure both quality and affordability. We've distilled all this knowledge into the V-Core 3, which was designed in partnership with Pawel Kucmus, a long time member of our on-line community and one of the most prolific contributors to the V-Core platform.

     

     

    PRECISION

     

  •    3 Point Kinematic Bed
  •  


     

     

     

     

  •    6mm Cast Tooling Plate for Print bed
  •  

     

  •    Bi-material Decouplers on Z arms ensure that any inconsistencies on the drivetrain won’t be transmitted to the print surface.



  •  

     

     

  •    XY Kinematics built to last

  •  

     

     

  •    All movement guided by MGN12 Linear Rails

  •  

     

     

  •    Doubled Z resolution with TR8x4 Lead Screws instead of TR8x8

  •  

     

    The V-Core 3 uses 3 lead screws to drive the Z axis of the machine. They move the bed down in small increments, at the end of each complete layer. The Z axis moves very slowly, so speed is not the priority - precision and resolution are. The V-Core 3 uses TR8X4mm lead screws instead of the TR8x8mm used in previous machines, effectively halving the pitch of the lead screw - this means that each rotation of the motor, now moves the bed half as much. This both doubles the Z resolution of your layers and multiplies the holding torque - always helpful when you're moving such a heavy bed, especially on the larger variants.

     

    ROBUSTNESS

    While previous V-Core versions, like many other printers on the market, relied solely on 20 Series profiles, the V-Core 3 is fully built on a 30 Series aluminium frame. From screws and nuts to brackets and plates, everything is bigger, stronger and tougher.


     
    •    Frame made with 30x30mm T-Slot aluminum with a beautiful black anodization
    •    4mm thick anodized aluminum plates
    •    9mm Belts
    •    Weight of Z drivetrain and bed is distributed across the Z motor mounts - not on the motors themselves






    •    Full End Stop solutions
    •    EVA 3 Carriage System provides mounts for most popular extruder and hot end choices on the market
    •    Shipping with EVA 3.0.2



     

     

     

     

    WHAT IS EVA?

     

    EVA is an independently developed and maintained project that aims to be a single platform for many extrusion types.

    Note that not all print head types (due to their physical dimensions) can reach the full print area.

    EVA 3 is the next iteration of the EVA platform with which V-Core 3 is fully compatible.

     

    SUPPORT

    •    Fully comprehensive step-by-step build guide (Both static and video)
    •    Fully comprehensive wiring and electronics guide for multiple controller boards
    •    Support configuration files for several firmware choices (Reprap, Klipper)
     

    SAFETY

    •    Wiring design includes multiple cable management parts, for cable clamping, guiding and strain relief
    •    Custom Keenovo Heat Pad with pre-wired 157ºC Thermal Fuse for extra safety (Optional). The wiring comes out of the pad slightly off-center, so it's neatly guided to the back of the machine without interfering with the bed mounting point at the back.
     
    •    For 120/220V Heat pad users, grounding point at the bed and fully isolated bed from the rest of the printer means that the printer frame is never conducting any dangerous voltages.



     

    CONVENIENCE

    •    Designed for a far easier and quicker assembly than previous versions
    •    Separate chamber for electronics ensures heat insulation, short motor cable path, easy access to all wiring, and a very clean installation
     

     

    *Panel for mounting electronics is not supplied, user is meant to source it locally. A 4mm thick polycarbonate sheet is suggested. Mounting screws and nuts are included as part of the base kit. DXF files with size, shape and hole patterns for the panels are provided on the project documentation.

    Electronics Panel should not be thicker than 4mm, otherwise it will not fit in the available space.

     

     

  •    IEC and LAN ports
  •  

     

     

    FULLY ENCLOSABLE

    ENCLOSURE KIT

    The V-Core 3 was designed from the ground up with full enclosing in mind, with no need for an external enclosure. The design ensures that all motors and electronics are safely placed outside the printing chamber, so they are shielded from high temperatures, and no machine elements protrude from the frame, ensuring that the frame can be directly covered with panels from all sides.

     

     

     

  •    The enclosure kit does not contain the enclosure panels, these must be sourced locally. DXF and STEP files are available on the project documentation for all panels on all machine sizes.
  •  

     

     

    MODDING

    The V-Core 3 is the perfect printer for advanced users who like to tweak and tinker with their machine:

    •    Fully open-source design, with downloadable 3D models and part libraries freely available
    •    Frame is built on a modular platform of T-Slot and V-Slot profiles, which allow for endless possibilites when it comes to mounting all types of parts
    •    Vast catalog of stand-alone parts available for infinite upgradeability: screws, nuts, connectors, brackets, pulleys, belts, electronics, etc.
