Voron 2.4 STEP 4: A/B Drives & A/B Idlers
This fourth step for building your Voron 2.4 consists of the components for assembling A-drive and B-drive and their respective A-idler and B-idler.
So the main components are pulleys, bearings and motors.
The blocks of A-drive and B-drive are then to be coupled to the blocks A-idler and B-idler in the next step via the aluminum profiles that make up the gantry. These 4 blocks are to be installed at the 4 corners of the gantry and will then manage the proper movement of the core XY system of the 3D printer Voron 2.4.
What are the features of this STEP 4?
- Pulleys: this step of the Voron 2.4 kit includes the pulleys for transmitting motion. These are GT2 pulleys, which come in black anodized aluminum.
- Motors: included in this step we find the 2 motors for the drives of the XY core system. We use Wantai nema 17 1.8° motors, stepper motors that are perfectly suited for use on 3D printers. They feature a rapido connector for easy installation and possible future replacement without rewiring.
- Hardware and other hardware: also included in the kit are all other useful fastening components, from screws to nuts. Also included are brass inserts to be used for plastic fasteners, as well as the flanged bearings needed for the belt drives.
- Cables for motors made in Italy: 4x0.5 blue FROR cable. FROR are flexible multi-core cables for power, signal and control transmission. PVC insulated and PVC sheathed. The main characteristics of FROR cables are: non-propagation of flame, non-propagation of fire, reduced emission of smoke, toxic and corrosive gases. They are suitable for transmission of signals and commands for interconnection of instrumentation and control systems with digital or analog signal transmission in outdoor environments, where increased protection against weather and especially ultraviolet rays is required. Due to their flexibility they can also be laid in gland chains.
Note for assembly
- In this fourth step for the assembly of the printer Voron 2.4 r2 care must be taken to assemble the parts correctly as indicated in the manual. In particular one must be careful about the force with which one tightens the screws that support the bearings and pulleys, as this operation will then determine the more or less forced sliding of the belt. In addition, attention must be paid to the different molded plastic blocks because they have references that allow only one orientation of the parts; they cannot be interchanged during assembly.
- Be careful when installing the motors in the orientation of the cable outlet.
- We include brass grub screws for attaching the plastics in the kit. These threaded inserts have a special spiral profile to ensure the best possible seal. Manufactured from high-quality brass, they have excellent thermal conductivity and corrosion resistance.
- Plastics are not included by default but are optionally selectable. If they are selected all structural and aesthetic parts will be provided. Aiming for maximum quality, we have narrowed down the possible choices to two materials: Nylon Carbon and ASA. The former has excellent physical-mechanical properties, and the latter, a viable substitute for ABS, has optimized mechanical properties, UV resistance, and allows for extensive color customization. We have divided the printed parts into three groups: STRUCTURAL - PRIMARY - SECONDARY. Using these combinations you can get a unique specimen by choosing from more than 200 color combinations. Customization makes your Voron 2.4 personal and representative of your style!
- Engine cables Wantai are made in Italy. Cables and connectors are supplied separately to be crimped. As an option there is the possibility to receive the cables already wired and sealed for connection with board Duet3D.
Voron 2.4: an introduction
The Voron 2.4 is a motion 3D printer design CoreXY with a fixed plane designed by Voron Design. This printer is known for its reliability and high performance.
Staying true to the fundamentals of the RepRap project, the Voron 2.4 is completely open-source, customizable and self-buildable.
The DHM kits of Voron 2.4 were born out of the need to gather the various requests of our customers: from those who struggle to find the material to those who have pointed out gaps and critical points in the kits already commercially available. The DHM kits are born from our experience in the 3D printing industry and knowledge of quality manufacturers. In addition, thanks to our in-house workshop, we have created custom components by making design improvements to give optimal reliability and performance.
The DHM kits from Voron 2.4 are currently available in 3 main variants that differ only in the size of the build space:
Kit Voron 2.4 250 mm → 250x250x250 mm
Kit Voron 2.4 300 mm → 300x300x300 mm
Kit Voron 2.4 350 mm → 350x350x350 mm
There is the possibility of some customization in some step of the kit, such as the choice of the extruder or the choice of the control board.
Do you want to build your own 3D printer Voron 2.4?
Our step-by-step kits for Voron 2.4 include 9 step + one optional tenth. In each step you will find the components for assembly accompanied by a manual with construction instructions and cautions.
We decided to divide the construction of Voron 2.4 into several steps to facilitate the assembly moments and also to allow for deferred purchase over time. We aim for quality and reliability of components rather than offering a cheap or incomplete kit.
Why buy a Voron 2.4 kit?
Owners of the Voron 2.4 praise it for its reliability and speed. Buying a kit printer allows you to customize various points: from the appearance, to the choice of size, type of electronics, extruder, and many others.
The Voron 2.4 DHM kit approach is to STEP: a step-by-step approach to building, each in his or her own time, a printer Voron. Each step has everything you need to finish that specific part of assembly, and this allows you to be able to pause the project and resume it without particular difficulty.
We have broken down and customized some of the steps in the official guide Voron into specific manuals for each step downloadable PDF. You will thus find step-by-step support for assembly. The manual for this step is available in the "Attachments" section of this page.
