Unfortunately, I can't order already made machine from aliexpress or similar. While there are people here reselling it from Aliexpress, they charge way too much.

So, I need an explanation for dummies. I already looked at OSSM, but I don't have 3D printer. I can buy a linear actuator motor at 24V from eco-worthy most similar to this one (https://mo.eco-worthy.com/catalog/worthy-12300mm-stroke-linear-actuator-1500n-57mms-p-431.html) Link will say insecure site, so I'll copy important info here for people who (righfully) refuse to open it.

• 1500N - this seems way too much for such use case
• 24V
• 200mm (8 inches) thrust
• duty cycle (15%) - I'm confused about this. On site it says this means it needs to idle for 17 minutes after 3 minutes of constant use. But is that under full load or no matter the load?

Since it's way overpowered, my intuition says I could run it for much longer than those 3 minutes, since it will be running under low load? Googling duty cycle said it means how much it needs to reach top temperature, but I didn't understand what exactly it means. Especially since there are 4 different duty cycles and I don't know which one this is.

I would prefer a motor like this, since it eliminates the need of transforming motor motion to linear. Also, if anyone has experiences with such motors, how exactly should one control them? I have ESP32 laying around I will probably use for this
