This is a long and detailed changelog for a 3D printing project, outlining the updates, improvements, and new features added to the design over several months. The changelog includes the date of each update and briefly describes the modifications made. Here are the main points highlighted: 1. **Improvements in Design (10/04/2015)**: - The direct extruder is attached to the carriage with 4 x M3 screws, making it more secure and easier to remove glue. - New belt holders were added for better stability and tensioning of the belts. 2. **Additional Features (10/06/2015, 10/08/2015)**: - A hair spray holder was added under the 2020 extrusion. - Corrections were made in the BOM (Bill Of Materials) file to provide more information about the required materials and components. - Updated BOM with util information on screws and nuts. 3. **Redesign of Z Axis (10/11/2015)**: - The design was changed by moving the Z motor from the top to the bottom, reducing the need for cables and creating a more stable platform for the bed structure. - A video demonstration is available at the link provided. 4. **Additions for Radds Board and Arduino Due (10/15/2015)**: - The piece connecting the Z screw to the bed was modified by removing the top holes. - Firmware for a 32-bit board radds1.5 was uploaded and found useful in speeding up print times, eliminating problems with speed and micro-pause. - Configuration file was also shared on thingiverse. 5. **Integration of Radds LCD (10/28/2015)**: - Repetier firmware was used and configured to work with a radds board, 20x4 lcd, SD card, 1/128 steppers, and watch dog active. 6. **Improvements and Upgrades (12/07/2015)**: - A new fan print file from thingiverse is suggested for cooling prints. - Improved BOM for better support for all users of the 3d printer model used to build this project: a custom printed arm supports a Windows tablet to slide the build platform and allow live control of printing progress in real time. An LCD panel update was added. 7. **Dual Hotend Configuration (01/03/2016)**: - A dual hotend setup project file ("two hotends.123dx") was shared, allowing for the use of E3D v6 or small extruders on a single carriage. 8. **Panel Update (06/03/2016)**: - Acrylic panels in white were added to all sides for aesthetic purposes. Instructions on using and accessing specific files were included at the end for users seeking help, especially firmware configurations suited for different versions of boards.
