Hey everyone, has anyone here messed around with micro linear actuators in their own custom mechanical builds? Like, I'm tinkering with this little robotic arm thing for fun in my garage, nothing fancy, just trying to get smooth precise movements without everything being bulky. Last weekend I slapped one onto a small prototype to lift a tiny platform, but the thing kept binding up when I tried adapting it to a weird angle mount I 3D printed. Wondering what folks do to tweak them for hobby-level stuff—maybe better brackets, different control setups, or ways to handle the super short strokes without losing accuracy? Feels like there's always some small adaptation needed to make them actually work in real homemade projects. Anyone run into similar headaches or found clever fixes? (around 170 chars here, but yeah, genuinely curious since my setup's kinda stalling now.)

Yeah, I've played with a few of those tiny ones in past projects, and they can be surprisingly capable once you dial things in. For my part, I ended up using small scale automation https://www.progressiveautomations.com/en-eu/pages/micro-linear-actuators from here in a couple of compact automation bits around the house, and honestly, what I like most is how little space they take up while still giving decent force for their size. In one build I had to fab a custom linkage just to convert the push-pull into a slight arc motion without too much side load stressing the rod—worked way better than forcing a straight-line setup. Speed control via basic PWM helped smooth out the jerky starts too. They're not perfect for heavy abuse, but for lighter hobby mechanics, the low power draw means you can run multiples off the same supply without drama. Just my two cents from trial and error.
