E-Bot Advanced Extruder Carriage

thingiverse

After wrestling with Bowden setups on my E-bot, I finally took the plunge and purchased a Titan by E3D. To install this, I created a new standard mounting plate for my E-bot, which has a pattern of holes that accommodate 4-40 nuts. This design provides exceptional strength and maximum flexibility in parts and upgrades. Also included with these plates are mounts for the Titan and E3D V-6 hotend, as well as a mount and duct for a 40mm fan. Additionally, there is a mount for a capacitive sensor to enable auto bed leveling and a mount for zip tying cables to the carriage. These parts were printed at a layer thickness of 0.2mm with two perimeters and 30% infill using ABS. Step and STL files are provided. ATTRIBUTION: The E3D Titan Extruder model found in the Step file was created by Ben Neubauer, as discovered on GrabCAD. KNOWN ISSUES: Belt clamps appear to be weaker than desired. Printing them with 100% infill may be necessary. The belt clamp is 2mm too proud, causing the belt to approach the carriage at a slight angle. This results in a distance of 12mm between the closest point of the carriage and the belt bearings. Using Pythagoras' theorem, we can calculate that this setup introduces an error of approximately 0.17 mm (0.0065 in) at the printer's extreme minimum and maximum points. Given the small nature of this error and how quickly small angles accumulate, I chose to prioritize a thicker plate over perfect belt alignment. EDITS: A left fan duct was added, providing space for hotend wires to run alongside it. The Titan Mount has been replaced with a new, more robust version. The original design suffered from an issue where the drive gear would push on the filament and bend the titan mounting plate backwards when the nozzle was too close to the bed. This led to part fatigue and eventual failure. A BLTouch mount was added as a remix. An RJ-45 jack mount was also added as a remix.
