Are this te plastic parts, but in aluminium? Thanks

not yet, but soon ! 🙂

Very well done putting these lists and everything together. You’ve convinced me to make the leap to motion!

Do you happen to have any images of the built up actuator arms and / or hardware installation?

Thanks!

Hi ! I am testing the 1610 right now. I use 6400 microstepping instead of 3200 so it’s quieter than 1605 at 3200. In terms of load, I can still stand on the actuator without any problem.
So 1610 is probably the way to go.
I will do more testing and a video as you ask.

Incredible setup there! congratulations.
With 10mm pitch ballscrew you should get 166mm/s at 1000rpm vs 333mm/s with 20mm pitch.
At 1000rpm that motor should be pushing around 5Nm safely… at least that it says the theory.
When you test your new actuator with 1610 ballscrew, would be possible to make a video with the actuator pushing at max speed alone?… To get better what is the real noise without all the background.

I already have a 1610 sfu that is need to test…
Here is a video.

Did you think in the possibility of using 2020 Ballscrew? These steppers seems powerful enough to drive them. You would need 3Nm for pushing 140kg cockpit (structure + driver) with only 1000 rpms, getting around 300mm/s from the linear actuator.

Could you publish a video of them working to get the feel about how the noise is?

I don’t know the exact rpm, but it’s slower than servo ones, around 100 mm/s.
They are mostly as noisy as servo ones.
It is annoying if you don’t want to use an headset or loud speakers.
