What's in the package

This time around we have edged even closer to a real full kit. We have paid attention to every detail down to the last wire you will need to assemble the kit. We will still offer barebone sets for those wanting to use different configurations!

-Mechanical Kit(coming soon): This bundle includes only the frame, mounting hardware, and all the motion hardware. You'll need to add electronics and all printed parts

-Essentials Kit(coming soon): This bundle includes the Mechanical Kit, and all the electronics needed to build a functional printer. You'll need to print the electronics case or make your own, as well as add the printed parts for the machine. A summary of the currently included electronics configuration follows.
- LDO 40mm Nema 17 motors
- Bondtech LGX Lite Extruder
- Phaetus Dragonfly BMO Hotend
- Custom Keenovo Heater with thermal fuse
- 5V M8 Inductive Probe
- BTT SKR 2.0 controller
- Raspberry Pi3A+
- GDS Time fans (4010 and 5015)

-Full Kit: This bundle includes the Mechanical Kit, the Essentials Kit, the Electronics Case bundle and printed parts. No extra parts needed except your locally compatible IEC power cable and an SD Card for the Raspberry Pi. All printed parts included (machine and case)
A summary of what's inside the electronics case bundle follows.
- Pre-drilled polycarbonate side panels, compatible with BTT SKR2, BTT SKR Mini and the BTT Octopus mainboards.
- IEC, Fuse, Spade connectors and pre-cut wires for your PSU and power connections
- Standoffs for your mainboard and Pi
- A 4010 fan for cooling
- All mounting hardware

You can get a detailed idea of exactly what is included, component by component by looking at the BOM section on the V-Minion Project Page!



-180x180x180mm Build Volume: Whilst many printers feature an ever-increasing build volume, the most common FDM prints are small. A smaller build volume means less moving mass, leading to faster and better looking prints.

-3060 Extrusion Frame: Utilizing 3060 extrusion for its frame, the V-Minion is extremely sturdy. This allows for faster printing with lower vibration, all leading to better looking prints.

-Linear Rail based Motion System: The V-Minion features linear rails (MGN15H and MGN12C) on all 3 axes, providing smooth and quiet motion.

-EVA Modular carriage system: The V-Minion features EVA as its extruder and hotend carriage platform. This means you can use a huge list of extruder and hotend combinations, outside of the ones we supply. There are many options. The great thing about EVA is that it will keep your printer open to updating: every year new hotends and extruders are released by so many amazing manufacturers. How cool is it that you get to simply re-print your print head and add a new hotend or extruder?

-Enclosed Electronics Case: All of the V-Minion electronics fit into the specially designed case. It has been designed to house the power supply, a Raspberry Pi3, as well as your printer mainboard, all whilst providing cooling via a built-in 40mm fan. The default design supports the BTT SKR2, BTT SKR Mini and the BTT Octopus mainboards. The side panels are CNC manufactured from 4mm Polycarbonate, making them incredibly strong, but can also be printed if you prefer.
-Precision Milled Bed: The V-Minion features a custom made, precision milled, 5mm bed plate designed for exceptional flatness and heat stability. Going one step further, we have worked directly with Keenovo, industry leaders in silicone heaters, to develop a bed heater which is both high performance, and safe due to its built-in thermal protection.



-Spool Holder: The on-frame spool holder is designed to complement the V-Minion. Based upon the same 30 series extrusion as the rest of the printer, it keeps your filament close-by and makes moving the printer a breeze because the filament comes with you.

-RatOS / Klipper ready: RatOS is developed by and in cooperation with Mikkel Schmidt especially for our printers. It combines the power of the Klipper firmware, as well as several other open-source projects, to provide a stable and easy-to-use operating system for all your printing needs.

-Comprehensive build guide: The V-Minion has a comprehensive step-by-step build guide in both static and animated forms. Each section is broken down into easy to follow steps, detailing the parts needed and how to assemble them. A fully animated build video is also provided, should you wish to see exactly how each part is designed to fit together.
