When I changed to MMM the Lehner got a lot hotter and in the last run too hot I guess :(
My Tekno NEU 1515 1y will probably arrive next week so I hope I wont have any issues with that one!

WOW!
That's all I can say.
I don't remember the actual numbers regarding the difference in the RdsON of the MM's FETs versus the MMM's FETs, but apparently it's a large enough difference to allow all of the "
HOT" motors we run to draw
ALL the current they want! Probably due to lower current-rise time, lower FET inductance, capacitance, etc. w/e. Anyways it's only a good thing. It means we can probably run a lower voltage or a slower motor and still make as much or near as much power with the MMM as we did with the MM, and thus not notice any decrease in performance, while being more efficient to boot!
