-=== Extruder Stepper Motor ===
+===== Extruder Stepper Motor =====
+The stepper motors are all (externally) unmarked. As such, gathering information for them is quite dificult.
+It is known that they are type NEMA 17, 2-phase hybrid bipolar. They are fairly easy to replace, however, as long as you know the specs you are looking to match.
