![]() Available both as a complete kit and a configurable kit (for those who want to select their own electronics).Weight of Z drivetrain and bed is distributed across the Z motor mounts - not on the motors themselves.Frame made with 30x30mm T-Slot aluminium with a beautiful black anodization.From screws and nuts to brackets and plates, everything is bigger, stronger and tougher. 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. 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. 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. The Z axis moves very slowly, so speed is not the priority - precision and resolution are. They move the bed down in small increments, at the end of each complete layer. The V-Core 3 uses 3 lead screws to drive the Z axis of the machine. Doubled Z resolution with TR8x4 Lead Screws instead of TR8x8.All movement guided by MGN12 Linear Rails.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.īi-material Decouplers on Z arms ensure that any inconsistencies on the drivetrain won't be transmitted to the print surface This means that while your plate is firmly in place, it can still remain perfectly flat as it expands. 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. Instead, 3 steel balls connected to the bed sit on low friction dowel pins. The V-Core 3 bed plate is not rigidly connected to the machine's frame. 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). Precision ¶īed plates expand as they heat up. 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. 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. 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. This kit is the culmination of Rat Rig's accumulated years of experience designing, producing and distributing DIY 3D Printer kits worldwide.
