The trimmer pot on the DRV8825 is of poor quality. It drifts in its setting and the metal ring on top is very fragile and subject to coming loose. I have made it my practice to remove the trimmer and wire on a larger but better quality trimmer. You use the same type trimmer on your adjustable-output switching regulators. Please consider upgrading these trimmers.
