I NeeD HeLp PLease AM882 a good choise

I see no reason to get the better ones.

I see a reason.!!!!. . . . They are better.!! . . . and the price difference is not enough to justify not taking advantage of there more advanced features like better resonance handling and stall detect. Has you well now there are other things beside incorrect tuning which can stall motors and on dual screw machine having the ability to alert and E-stop the machine is worth the slight extra cost IMO.

Oh and from the few times I've used the DQ869MA the AM882 give much smoother performance from the motors at lower feeds.!!
