This appears to be a detailed guide on how to upgrade an E3D Chimera 3D printer kit with a custom carriage design. The guide covers various aspects of the upgrade, including: 1. Design modifications: - Two small holes are added on each side of the carriage for easy access to print head adjustment screws. - The circuit board is relocated back onto the chassis and mounted using cable chain mounts. 2. Parts List: - A list of parts required for the upgrade is provided, including screws, heat sets, thumb screws, and other components from McMaster-Carr. 3. Installation Instructions: - The guide provides detailed instructions on how to install the bearings in the new carriage. - It also explains how to assemble the print heads as per E3D V6 instructions and attach them to the heat sink. - The heater and thermistor cables are routed through the chassis, and the original heater connectors are installed. 4. Extruder Upgrade: - The guide recommends switching to Bowden extruders and provides a link to purchase a left and right kit. - Some cutting of the plastic case may be required for easy access. 5. Wiring: - The wiring instructions involve pulling back all the wiring from the original carriage, plugging in the extruder steppers, and running thermistor feeds from the carriage circuit board to the carriage. - A 12v run is added for permanent power to the heat sink fan, and a feed is created for the layer cooling fan. The guide also mentions that it will cover extruder alignment and position settings in future updates.
