What's there to know about linear actuators? I've figured out my lift table / desk and got it working, sort of. It has a single 24 volt motor driving a hex shaft to power the two legs.
The power supply is missing but it works on an 18 volt Ryobi battery. While I don't really need it, it's a fun option.
The thing that threw me was that without the motor in the drive train the actuators allowed the table to lower via gravity. I assume the actuators are basically powered lead screws and I was surprised that they settled. Pushing or pulling on a threaded device doesn't usually get the devices to move.
I will likely add some limit switches and bits and pieces to control over stressing the mechanisms.
