I’m as well a bit curious as to why I need to update firmware with this new hot end. It’s just a new hot end. Why would anything need to change when it’s still a 12v heater cartridge and thermistor. I’m regretting getting this hot end already having not known about having to deal with firmware changes. I’ve got an Anycubic I3 Mega and it once printed fine but my issues most likely reside in the bed carriage assembly. The ONLY difference I see and like about the E3D hot end is your clipped on heat sink fan. What really is the magic about your hot end that makes it a step above everyone else’s? I’m just curious.
