What is the Extruder type?

I was looking to see if I could replace the extruder with the single flexion extruder by diabase. I do not know if this will work or if you can even swap out the extruder. Please help.

I think you can adapt 3rd party extruder/hotend as long as you are still using the original stepper motor and the extruder gear.

otherwise, you have to use Gcode.
