Copymaster3D Voron2 V2.4 R2 Kit – 250 × 250 × 250 mm

The Voron 2.4 R2 kit from Copymaster3D is the ideal choice for experienced 3D printer users who want a top-tier CoreXY printer with high speed, rigidity, and wide customization options. The version with a print volume of 250 × 250 × 250 mm is compact but still large enough for most functional parts, prototypes, and hobby projects.

This is a KIT, not a completely assembled printer. It is supplied without printed plastic parts and without Raspberry Pi.

Key Features

• Print volume 250 × 250 × 250 mm – universal workspace for most applications.
• CoreXY kinematics – high speeds and acceleration while maintaining excellent print quality.
• BTT Octopus v1.1 control board – modern, powerful 32-bit board with plenty of room for expansion.
• Quality mechanics – precise linear rails, quality belts, and a solid aluminum frame.
• V6 style hotend with titanium heatbreak – proven design with a bowden extruder, suitable for a whole range of filaments.
• Open project Voron Design – rich community, manuals, STL files, and modifications available online.
• Easy upgrade capability – compatibility with hotends like Phaetus Voron Dragon or E3D Voron for switching to direct drive (Afterburner/Stealthburner etc.).

What the kit contains

The Copymaster3D Voron2 V2.4 R2 Kit contains all essential hardware components for building the printer:

• complete aluminum frame (profile system)
• linear rails and bearings
• belts, pulleys, screws, and fasteners
• heated bed (silicone heater)
• BTT Octopus v1.1 control board
• stepper motor drivers (TMC 2209 series/compatible – according to specific delivery)
• stepper motors for axes and extruder
• V6 style hotend with titanium heatbreak
• bowden extruder and PTFE bowden
• power supply/supplies, cabling, connectors, fans

The supplier states that the package contains all key parts according to the BOM (Bill of Materials) for the Voron 2.4 R2 in the given size.

Not included: 3D printed plastic parts, Raspberry Pi, some cosmetic accessories, and potential modules for specific modifications (Stealthburner, Klicky, LED, etc.). These parts must be printed / purchased separately.

Who is the Voron 2.4 R2 suitable for

• Advanced 3D printing users who want a fast and precise printer and don't mind building from a kit.
• Makerspaces, schools, and laboratories that want an open and modifiable platform.
• Production of functional parts, mechanical components, holders, fixtures, and prototypes.
• Users planning to print technical materials (ABS, ASA, PETG, PC etc.) and requiring an enclosed, solid, and heated space (after completion of build and enclosure according to Voron documentation).

Advantages of the Voron 2.4 R2

• Printing speed – CoreXY construction and a lightweight moving system allow for very high speeds without dramatic loss of quality.
• Rigidity and stability – a robust frame minimizes vibrations, which translates positively to the print surface.
• Modularity – easy replacement of the hotend, extruder, electronics, or adding sensors, LED lighting, and other elements.
• Community – extensive user base, guides, slicer profiles, recommended modifications, and supported upgrades.
• Open‑source origin – full control over firmware (usually Klipper/Marlin), possibility of tuning and customization.

What else is needed

To successfully put the kit into operation, you will need:

• printed plastic parts according to the official STL files from the Voron Design website
• Raspberry Pi (recommended for operation with Klipper firmware)
• basic tools for assembly (hex keys, screwdrivers, crimping pliers, soldering iron as needed, etc.)
• slicer software (PrusaSlicer, Cura, Simplify3D, OrcaSlicer, etc.)
• corresponding filaments – PLA, PETG, ABS/ASA, or others depending on requested applications

Main benefits for the user

• You build your own "high‑end" printer on the level of top desktop machines.
• Thanks to open construction and community resources, you can learn, tune, and further improve.
• The compact 250 mm dimension saves space on the desk but at the same time provides sufficiently large volume for serious projects.
• Suitable as a main work machine in the workshop or as a powerful addition to existing printers.

Tips for a successful build

• Before starting, go through the official Voron 2.4 R2 manual thoroughly and verify that you have all required parts and tools.
• Print the plastic parts from a dimensionally stable material (ABS/ASA recommended) – this minimizes deformation when printing in an enclosed space.
• Continuously check the squareness of the frame and smooth movement of the linear rails – precise mechanics are key to quality printing.
• After assembly, spend time on calibration (PID, flow, input shaping, pressure advance) and creating quality profiles in the slicer.

Key Features:
