SolidCore CoreXY Gantry

SolidCore CoreXY Gantry

This is the gantry and carriage design for the SolidCore CoreXY printer.

Gantry Design

The SolidCore Printer design currently uses a bowden tube setup to allow for higher acceleration but a direct drive extruder soon be added to allow for higher feedrate. 

Aluminum Gantry / Carriage

Although the design is uses all metal parts, the carriage and gantry are designed to be light weight and strong. We currently use c-shaped aluminum stock because it reduces machining time. The reduced machining time and minimized waste helps but it’s a compromise will most likely change soon as the y-axis linear rail will be reoriented into the a vertical position similar to the RailCore. The SolidCore uses this mechanical arrangement will so it's easier to adapt an E3D Toolchanger.
