The plan is to design a modular 3d printer that has the following design goals:
CoreXY Kinematics
Simple but Compact Design
Scalable - large format 3d printer build or small mini 3d printer
XYZ-Axis Linear Rails
BOM Parts List uses standard and available 3d printer parts commonly used so people can convert their printer into a SolidCore.
Enclosed or Available Enclosure
All Metal Parts or printable or Laser Cut Options
Open Source
Lightweight Gantry for High Speed 3D Printing
Kinematic Coupled Bed
Triple Z-axis or 3-Point Bed Leveling
Belt Driven Z-Axis
Direct Drive or Bowden Extruder
DIY Build Plans
Crossed Belt Path or can be modified to HBot Kinematics
ToolChanger or Available Tool Changing Option
High Temperature 3D Printing
Community Driven Design

We’ll probably make some changes such as reorienting the the y-axis linear rail into a vertical position similar to the RailCore, redesigning the carriages and motor/belt mounting plates where the z-axis motors are placed on the bottom of the machine. When I first designed the plates I thought it would look cool with the motors on top but after I machined everything I realized that moving the bed up and down could cause deflection in the main plates. I’m also considering making the carriage components and rail support one piece similar to the latest update on E3D’s Tool Changing printer.

We’re working on a small budget lol which “recycling” parts from previous builds. For example the bed is made from 3/8 inch thick aluminum that we robbed from an old printer. We’ll change that to 1/4 inch thick once we get more money.

The left motor plates are going to be re-machined to give room for a tool changer setup.

The overall footprint of the machine relative to print volume is somewhat excessive. In order to have a solid enclosure design I had to move the motors inside the frame boundary. This sacrificed the overall printer size to print volume ratio.

This design was inspired by the RailCore, HyperCube Evolution or HEVO, D-Bot, Mike Fisher’s QuadRod and Maarten van Lier’s corexy build.

I'll update the files when finished but there’s still a lot of work to be done.
