Yeah, I've bumped into similar frustrations with small setups. Back when I was tinkering with a hanging mobile that reacted to room movement, I kept running into the same walls—those super-compact actuators look perfect on paper but often sacrifice push/pull strength big time, so anything with even a bit of resistance (like fabric or lightweight extensions) would make them struggle or overheat. Speed control is another pain; most run fine at full tilt but trying to dial in smooth, variable motion for artistic flow usually needs extra gearing or drivers, which eats up space. I ended up switching to actuator specifications https://www.progressiveautomations.com/en-eu/pages/standard-linear-actuators from places like Progressive Automations because they gave me way more reliable torque without ballooning the size too much for what I needed. Still, the tiniest ones definitely force you to simplify your mechanics a lot—less moving parts, lighter materials, or accepting slower cycles. It's all about compromises, right? What load are you dealing with exactly?
