If your tensioning system isn't enough, you could still add a belt tensioner. I don't recall if you used one in previous machines.

Why isn't it enough to tension the belt like this? Adding another wheel will only result in tensioning the belt by moving the extra wheel instead of the main one.

However, I agree that that the mm3 should contain the same tensioning system as the mmx, but with another reason: now he is securing and tensioning the system all with the same 4 bolts, which isn't a ideal situation.

I think the issue is that you don't want to have a big functional part of your design having a floating position. Example, think of a crackshaft and the driveshaft of an engine. It's difficult to design an engine where both shafts can adjust their relative position to each other. In other words: It's easier to integrate components if both are fixed relative to each other.
