When I printed the first things with my new Anycubic i3 Mega, I realized that the cable strand to the extruder is very sharply and often bend due to the fixing directly at the extruder. Here, I am afraid to get cable fatigue after some weeks. Therefore, I printed a small cable guide which makes the extruder cable bending much more harmonic and less concentrated to one point. Also, the cable is now behind (and not beneath) the upper bar when moving the extruder at higher Z values. I fixed the new part with a cable strap to the extruder casing, and the same I did with the cable-strand at the upper end end of the new part.
