Hi, Bruce,
Thanks for the explanation re the terminology and different systems.? I have the same Geeetech model that John has, and the extruder moves in the X-axis with the hot end mounted under the extruder, connected by a short (40 mm?) Bowden tube which is lined with Teflon.? The hot end is wrapped with insulating material.? I didn't realize that the extruder is fixed to the frame in some models, but I have little experience with 3D printer models in general.
