Hello, dont know if this is the correct place for this. If it is not, I apologize.

BTW, I signed up here a while back but never did come back so kind of new here and not too savvy with the groove of this place.

Okay, here is my question.

How important of a feature would it be to have the ability to very easily change the stroke of a machine from, say, 2mm to 5mm without tools or taking the machine apart, just the simple turn of a knob . The longer the stroke, the more the rate of descent increases, not just over all faster but slower at the beginning of the stroke and faster at the end, snappier. Some people prefer long, some short but was thinking if you can change it so easily, would it be a welcome feature to be included in a rotary, or just be considered gimmicky?
