Oops, I meant nothing was as easy as a geared stepper motor. All the power of a geared extruder, with the simplicity of direct drive.
Geared extruders look great, and on a cartesian are fine, on a delta, they can look clumsy and out of place, but the gear ratio is the best of the three systems. We solved that on the Griffin by using a larger hobb to dial back the gear reduction (it rocks).
I was doing ABS and PLA mixed gears (ABS pinion for heat), and it was a nightmare, some people have better luck than others. I still have a direct drive sitting as spare, as well as a geared extruder.
