@DdotCdot posted:the more I think about it, the more I’m thinking it might be wise to just disconnect and drive both units heaters off a single buck converter, together in parallel, separate from the boards, since I won’t want to mess with turning those off via tmcc anyway and would rather give my irreplaceable driver board a greater chance at longevity without heaters being driven off of it and just leave it to do its job with the fans and the proper sequencing.
I'd just run it until it fails, chances are pretty good you'll get years of service and be able to enjoy all the cool features. If I wanted a neutered one with lame smoke control, I could have kept the MTH model. I plan on using the cool features until they don't work. At that point, I'll take a stab at repairing the board, which I suspect is quite possible for many failures. When all else fails, then it's time to get out the bandaids.
