v2 Hotend - What are the firmware differences?

I’m looking in to buying a new v2 toolhead to upgrade my Taz 4 and was wondering what the differences were between the v1 toolhead firmware and the v2 toolhead firmware?

I’d like to be able to continue to use the old toolhead for different temperature materials and if I know the firmware differences I may be able to do a custom code modification to allow swapping without complete firmware switches. I just want to make sure I don’t miss anything.


Why download it and compare.
