Hey guys Ive been out of the loop for a while but I'm back and upgrading my Eclips3d, I have the Titan extruder and E3dv6 my question as I am still a newb is should I go direct or bowden? not really sure of the pros and cons of each. if someone wouldn't mind cluing me in that would be great.
Direct drive will give you less stringing and is a bit easier to use, but harder to implement and it adds more weight to the print head. Bowden may cause some stringing, but it will usually give sharper edges since there is less weight on the print head.
I personally don't have a favorite, some prints I would prefer direct and some bowden. Either way, as long as you use the e3d titan you really can't go wrong!
If you want to use flexible filaments a direct drive work be a better option. To keep the weight down you can use this pancake motor with the e3d Titan. It works just fine; I have been using it for many months.
The motor does need to be the other way round. You can reverse the connector for the motor to change the direction or do it in the smoothie config. You'll definitely need to change the number of steps due to the gearing. I think there is a recommended value on the titan website, which I used as a starting point and then retuned slightly.
