Where do I start?

To begin building an OpenHornet, here are some steps to get you started:

Research and Familiarize

Start by thoroughly reading the OpenHornet documentation included in the release manual, including the engineering drawings, construction plans, and any available resources. Understand the project requirements, components, and overall construction process.

Join the OpenHornet community on platforms like Discord. Engage with fellow builders, ask questions, and share progress updates. The community can provide valuable guidance, support, and troubleshooting assistance throughout your build.

Prepare a dedicated workspace with adequate lighting, ventilation, and a sturdy workbench. Organize your tools and materials for easy access and efficient workflow.

Make a list of the required materials and tools based on the OpenHornet documentation. Ensure you have all the necessary components, hardware, and tools before starting the build (or at least the assembly you are building!)

Begin assembling OpenHornet by following the step-by-step instructions provided in the OpenHornet Build Documentation. Pay close attention to the details, measurements, and guidelines to ensure accurate construction.

Building OpenHornet is a meticulous process. Take your time with each step, ensuring precision and accuracy in your work. Double-check measurements, alignments, and connections along the way to avoid errors.

Once the construction is complete, thoroughly test each component and system to ensure proper functionality. Address any issues or malfunctions promptly, referring to the troubleshooting resources available.


Remember, building OpenHornet is an involved process that requires patience, attention to detail, and a passion for building. Embrace the journey, enjoy the learning experience, and don’t hesitate to reach out for help when needed. Happy building!

Research and Familiarize

OpenHornet is currently about to release its Beta1 release. As an early-stage beta version, please keep in mind that not everything may work perfectly. We appreciate your support and patience as we work diligently to refine and enhance the simulator. Your feedback and bug reports are invaluable in helping us create a top-notch experience. Stay tuned for the Beta2 release, which will include even more exciting features and improvements. Let’s embark on this exciting journey together and make OpenHornet even better!

Embarking on the self-fabrication journey of OpenHornet requires a comprehensive evaluation of your shop and capabilities. To successfully undertake the project, you will need the following essential tooling:

CNC ROUTER

OpenHornet assumes you have a X-Carve 1000×1000 CNC Router. (750x750mm working area.)

You will primarily be cutting MDF wood, acrylic, ABS, and thin aluminum sheets.

A handful of parts will exceed the size of the router bed and will have to be done in multiple operations.

LASER ENGRAVER/CUTTER

A K40 laser with a Lightburn capable mainboard and air assist is the minimum assumed capability.

You will primarily be cutting/engraving clear, white, black acrylic and Rowmark.

FDM 3D PRINTER

Prusa i3 MK3 minimum capability is assumed

You will primarily be printing in PETG.

SLA/DLP 3D PRINTER

Anycubic Photon model is the minimum assumed capability. (The bigger the work area and the higher the resolution is better.)

HAND TOOLS

Common hand/power tools including (but not limited to) a drill press, hand drill, screwdrivers, sanders, wrenches, ratchets and sockets, calipers, tape measure, ruler, square, clamps, marking devices, files.

ELECTRICAL TOOLS

Basic SMD electronics assembly equipment including (but not limited to) a multimeter, soldering station, magnifier (optional), SMD reflow station, desolder vacuum, desolder braid, solder, flux, ESD protection

Remember, this list provides a minimum guideline, and depending on the complexity of your build, additional specialized tools and equipment may be required. Assessing your existing tooling capabilities and acquiring any necessary equipment will ensure a smooth and successful OpenHornet fabrication process.
