I wasn't very pleased with the print quality of the D-Bot with Bowden tube extruder. Especially PETG had lots of blobs and strings.
So I want to try out the Titan. I mounted it with a readily available angled steel bracket as close to the linear rail carrier as possible.
The bracket holds the Titan with three of the longer screws provided by E3D. I also had to add a 2mm thick damper between stepper and gearbox. Otherwise the pinion gear would be too high.
I couldn't test it yet, because I forgot to order the M7 heat barrier, so I couldn't fit my cloned Volcano hotend.
Although my D-Bot has linear rails, it might give standard D-Bot owners an idea, how it could be done.
I'd like to make a bracket that holds the Titan rotated 90° next to the D-Bot carrier, but my CNC mill isn't up to the task yet. ( too many projects... )

PETG indeed keeps oozing, is sticky, direct extruder is the way to go and in fact no need for Bowden when you make the carriage plus extruder lightweight (I am down to 250g). You could shed some weight by making a new carriage instead of this steel bracket. A shorter motor eventually.
