Yeah, got a couple of Makergear M2 Duals as well. (It hasn’t been much of a conflict lately though, the 
has been getting all of my attention for the last couple of years.)
I hear Makergear has come out with an M3 Dual now though - independent dual heads and Wifi control. (And it’s been out long enough that the kinks are probably worked out.)
Might be time to revisit.
