Be the first to review this product

Upgrade your V-Core Pro v1.x to the latest V-Core Pro v1.3.

v1.3 is the final iteration of the V-Core Pro. Developed on top of the v1.2 build, this version completely redesigns the Z axis of the machine to incorporate the 3 point kinematic bed feature which we introduced in the V-Core 3.

Printed Parts information

Upgrading from v1.0 or v1.1:
You will need to upgrade all axis(XY + Z), which means you need both printed part packs. You can find them in the STL folders or order them from us (select both options).

Upgrading from v1.2:
You have the option of upgrading the Z Axis only. There are some very minor changes to the XY plastic parts when compared to the v1.2:
- Stronger idler housings
- A few extra millimeters of Y space
Upgrading the Z only will give you 'almost' the full v1.3 machine without having to dismount the XY axis. If you want the very latest and final version of the V-Core Pro you will need to print/order both printed parts packs.

Extra Z Motor

If your current version of the V-Core only uses 2 Z Motors, you will need an extra motor/driver.

User Testimonials

The new v1.3 comes with the most precise Z drive mechanism I ever found in a 3D printer. After one trim operation, the bed squareness is below 0.02mm on a 300x300 bed. It doesn't get better than that! Simple and clear: it is a huge improvement for the Z axis. The old concept with two rails on the sides never glided as smoothly as the new one - there was always a bit of friction in the rails which caused noise. I didn‘t know any better and thought it was standard for a machine with 3 z motors, and I was a bit skeptic about the new design. Now, after one month of operation, I know better. The new Z drive is smoother. It runs so silent I can be in the printer-room and don‘t notice the moving bed.
- Detlev Rackow

Much easier to assemble and get right. Much better bed support, especially on large beds. I went from a 1.4mm height variance to just 0.3mm on the 1.3 on my 500mm bed! That's just INSANE! I would highly recommend this upgrade to everyone!

Precision

- 3 Point Kinematic Bed


- All movement guided by MGN15 Linear Rails

 



Robustness

- Frame made with 2020 and 2040 V-Slot aluminium with a beautiful black anodization
- 3mm thick anodized aluminium plates
- 9mm Belts
- Weight of Z drivetrain and bed is distributed across the Z motor mounts - not on the motors themselves

EVA 2.2.1

- The EVA 2.2.1 Carriage System provides mounts for most popular extruder and hot end choices on the market (Bowden, BMG, Titan, Aero, Hemera, and more to come!)

What is EVA?
EVA is an independently developed and maintained project that aims to be a single platform for many extrusion types.
**Dragon Hotend** and **Orbiter Extruder** support incoming!
Note that not all print head types (due to their physical dimensions) can achieve the full 300x300 print space.

EVA 2 is the next iteration of the EVA platform with which V-Core Pro is fully compatible. Most vivid improvements since the last iteration is the improved front belt clamp feature (no more zip ties!), improved contribution system, more ease of assembly, modular X endstop system, dedicated cable paths and shrouds (for ascetics).
