Can't figure out how to use snappy

If I may advise, switch to filametrix. I've been testing the hub cutter for a long time but need to debug the forming tips. That's not the same for all the different filament manufacturers.

yeah, i've considered that, but i'd still like to try snappy first. do i use the macro from happy hare? (https://github.com/moggieuk/Happy-Hare/blob/main/config/addons/mmu_erec_cutter.cfg)
if yes, do i need to install happy hare, or just the cfg?
