I realy hope that MGM will take care of use and take this message in consideration. I've a 16018 that i've bought from Mike at RCM who did the same thing too, and yes, for a +/- $400.00 controller it's very frustrating.
I'am sure that MGM can do something for it or Mike at RCM can place little pressure at MGM to solve this problems.
For me, i wait to buy an MMM and my MGM will stay sitting here, maybe to drop on a little 1/10 project latter.
A $400.00 controller, with 160A of capacity, and about just good to drop in a little 1/10 low amps conversion
