This "Configurable kit" is meant for advanced users who know what they're doing and want to have control over what components go into their machine. If you're just looking for a kit as complete as possible and don't want too many choices, you should probably be looking at the V-Core 3 Standard Kit.
WARNING: Currently the Raspberry Pi option is not avaible to order! Due to worldwide shortages, we have run out of sourcing options! As individual users you may still be able to source your own Raspberry Pi. Locate a RPi near you at RPI Locator.
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.
Bed plates expand as they heat up. If their mounting points are unmovable, the bed will have no room to expand to the sides, and it will be forced to bow (either upwards or downwards). The V-Core 3 bed plate is not rigidly connected to the machine's frame. Instead, 3 steel balls connected to the bed sit on low friction dowel pins. The pins act like a pair of rails for the steel balls, guiding their movement as the bed expands and ensuring that only radial movement is possible - there's zero margin for lateral movement. This means that while your plate is firmly in place, it can still remain perfectly flat as it expands.
Since the bed only has 3 mounting points, which are connected to 3 independently driven Z motors, bed-levelling is exclusively determined by motor position and can be done 100% electronically - simple and instantaneous.
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.
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.
*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.
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.
You may share, remix and mod the design. By default, you may not use the design and its derivatives for commercial purposes, but if you request a commercial license from us, we may (and most likely will) grant you one, as long as we deem your goals are aligned with the best interests of the project and its users.
The spirit of the project is to remove barriers to innovation and focus on pushing the technology, working as a collective, inspiring each other and experimenting with new ideas. We are happy to foster a rich ecosystem of suppliers and services that empowers users by offering them more options and alternatives.
Internally, the Rig Kontrol seems little changed. NI say that the converters have been improved, and it certainly sounds very clean, but then so did its predecessor, to my ears. The Rig Kontrol still connects to your computer via a USB2 port, and the driver has been tweaked to provide more informative options for buffer sizes. It seemed happier to run at low latencies in my system than the Rig Kontrol 2, and I experienced none of the occasional clicking that I found with the previous version. In general, I imagine most Rig Kontrol 2 owners will be content to stick with their existing hardware, though.
Ultrasonic is a versatile high-gain amp for metal and modern rock sounds.Another cool live-oriented feature is Snapshots. Hit the miniature Rig Kontrol icon above the gear rack and a virtual floorboard appears at the bottom of the rack, as before. In Guitar Rig 3, however, the options that appear when you right-click on an unused button include Snapshot. Choose this option and name the result, and hitting that button thereafter will recall all the parameter settings for all the components in the current preset. The idea is that if, say, you want to tweak a preset in various ways for the different sections of a song, you can simply store and recall a couple of Snapshots. This is infinitely easier and neater than trying to shuffle between three or four variations on a preset using the Next and Previous buttons. You do have to remember to re-save your preset after setting up Snapshot assignments, though.
Finally, it seems to me that preset switching is more seamless than in GR2, which is obviously a good thing for the live player. It sometimes takes half a second or so to respond, but there are no glitches or pops when you switch sounds or add a new component to your current preset.

SoftwareThe Mac and PC-compatible software (which can be purchased separately from the hardware) is the heart of the Guitar Rig 3 Kontrol Edition system. When you plug your guitar into Guitar Rig 3 (by way of the bundled hardware), the software allows you to call up preconfigured or custom combinations of amplifiers, speaker cabinets, and effects. Every nuance of a professional guitarist's signature sound has been accounted for--from the characteristics of overdriven tube amplifiers, to the diameter of the speaker cone.
In general, there are three ways to take advantage of the Guitar Rig 3 software: browsing presets, creating custom rigs, and performance. Stepping through the more than 300 preset configurations offered in Guitar Rig 3 is like walking through rock and roll history. Each Guitar Rig 3 preset is categorized by genres such as classic rock, metal, or country and blues. A search option allows you to find presets using attributes tags such as Bright, Dirty, Spacious, or Warm.
After getting a feel for what Guitar Rig 3 is capable of, we played around with creating our own custom setup. An exhaustive list of components that includes 12 guitar amps, 17 speaker cabinets, 44 effects, and 9 microphones, made us feel like a kid in a candy shop. To get around a licensing nightmare, presumably, Guitar Rig 3 uses thinly veiled names for their components that allude to their real world counterpart, such as Twang Reverb (for Fender Twin Reverb), Citrus (for Orange), and Gratifier (for Mesa Boogie Rectifier). Creating our own custom rig was as easy as dragging and dropping components from the list window into the rig window, and hitting save.
Those of you brave enough to take Guitar Rig 3 out of the bedroom studio and onto the stage can create your own custom bank of presets that can be switched on the fly during a live performance. The advantage of using Guitar Rig 3 on stage is the amount of flexibility you have to dramatically shape your guitar's sound using just the included foot controller. For instance, during the course of a live set you may have one song that demands a clean, vintage guitar tone with a delay effect, another song that requires the sound of an overdriven full stack, and a song that needs an intimate, bluesy tone, drenched in reverb. Using Guitar Rig 3, you can jump between complex configurations just by stomping a single button on your foot controller to advance to the next preset, instead of fiddling with the multiple knobs and buttons of traditional amplifiers and effects.
HardwareThe rock-solid foot controller included with Guitar Rig 3 Kontrol Edition measures 15 inches wide, 9.5 inches deep, and 2.5 inches tall. Constructed primarily of black anodized metal, the Guitar Rig foot control is heavy enough to stay put and rugged enough to withstand some serious abuse.
The top of the Guitar Rig foot control features 8 stomp-worthy switches that can be assigned to any parameter within the software, such as effects, mute, tuner, tempo control, and advancing through presets. A large metal expression pedal takes up the right side of the Guitar Rig foot control, allowing you to smoothly control effects such as wah-wah and delay, or use as a volume control. 041b061a72
