There is a lot of hate for the Titan. I think in terms of a long Bowden it isn't a great choice. I had mine working but the moment something was off, like the nozzle being just barely too close to the bed, it skipped or chewed filament. That said I do not think it is a universally bad extruder. I've been using 4 in my almost direct drive setup (see farther down in this forum topic) and have had no extrusion issues across all 4 with many prints. Was the Titan a good fit for a 790mm Bowden? Probably not. Was E3D going to sell us a competitor's Bondtech extruder? Of course not. Did E3D know they were coming out with Hemera eventually when they started shipping ToolChangers? Probably. Should E3D have delayed TC even more for Hemera or announced the Hemera early before they had something sell? No, does not make good business sense. Were you given the option to exclude Titan's with your order without affecting anything else? Yes. Given all of that the only complaint I would have is E3D did not share just how much tweaking would be needed to get the Titan's working with this Bowden setup. Aka it is a pain in the butt. As others have mentioned the TC is not for beginners. I ordered the TC kit with the view that I would try Bowdens, but ultimately I would switch to a direct drive setup or nimble (for so many reasons that don't even have to do with the Titan). I think if you were going to wait for anything you should considering waiting for E3D (or other manufacturer) to pair a compatible pancake stepper with the rest of the Hemera to save space and weight. I'm running pancakes on my titan setup and they're working fine.
