PWM can make a pretty big difference, especially with micro actuators where even small speed changes are noticeable. I used it on a miniature panning system for a model build, and being able to slow the actuator down helped a ton with stability. The only catch is making sure the signal is clean — noisy wiring can cause weird jumps. If you’re comparing options, https://www.progressiveautomations.com/pages/micro-linear-actuators has a few PWM-friendly units that show their speed ranges clearly. For lightweight mechanisms, PWM usually makes things feel much more controlled.
