Hi Keith. What is the difference between these?

Since TTL is a clone of BMG, I could not understand why there is spesific choices for BMG and TTL.

As I up to know, both have the same gear ratio and have a good starting point for E-step as 415.

Trianglelab DDB 2.0 doesn’t require extruder direction inverting, but a genuine BMG does, so the options do different things.
