doesnt matter if you only use one I have a flying extruder setup here and took a right handed..
all depends on the setup..or on a multimaterial printer if you want a mirrored extruder setup.
The extruders are sold without motor, because you have to decide what you need.
More torque or is a pancake motor sufficient?
I got my Anycubic Delta for Christmas last year. Honestly, there's nothing left of the Anycubic except for a few screws.
Meanwhile the frame is 1m high and has a print bed of 300mm.

I love working on it.
