Project Chimera iXY Release 2.4

RepRap Speed.
Zero Compromise.

A fast 3D Printer using CoreXY kinematics, built from two different bedslingers; the Flsun i3 2017 and Mingda Magician X. Demonstrating the usability of RepRap in modern printers.

Still printing. Still free. Still RepRap.

Status: Version 2.4 Released. Check Github for firmware and models!

Reprap precision unleashed

CoreXY + Direct Drive

The gantry system uses a rigid frame made completely from salvaged extrusions. This allows for minimal flex and vibrations during high-speed movements.

E3D's V6 Volcano Hotend paired with the Titan Extruder allows for extremely high flowrates, and thus print speeds.

To reduce effects of VFA and ringing at higher speeds, the kinematics involve a hybrid linear rod/rail XY system versus the original T-slot extrusion design.

Toolhead Detail

Automated Nozzle Cleaning System

No more constant watching of first layers or flush cutters. The nozzle purge system reliably pressurizes the melt zone and cleans the nozzle for a 'print-and-go' system.
