I was inspired to design my own 3D printer and this is the 2nd generation of this printer. The design goal is to be able to rapidly produce large mechanical parts for rapid prototyping and allow for soluable supports to allow for more complex designs.

The main features that have been realized in this itteration is the use of steel rods for the X-axis rather than aluminium extrusion. Addition of two part cooling fans. Use of two volcano hotends instead of the standard v6. Redesign of the Z-axis mounts.

Changes in progress:

1. Redesign of the extruder carriage to to be more compact and lighter

2. Modify the Y-axis mouns to a single larger part

3. Improve the rigidity of the upper portion of the frame

4. Improve cable management

5. Develop instructions and a Bill of Materials

6. Edit the firmware and release it

7. Add the option to use the color mixing diamond hotend
