Rotary servo 3DOF platform

Hello, dear colleagues!

I would like to apologize for my text, I use a translator.

I decided to fulfill my long-standing dream and build my first 3dof platform for motion simulation.
To begin with, I built a 3d model in SolidWorks:


As drives, I chose the 80ST-M02430 servo drive (A1-SVD15 driver) with a NMRV063-50 worm gear (1:50):


After completing the working documentation, I placed an order with the factory. The parts were manufactured quickly:


When the parts arrived, I started assembling. There were no difficulties with the assembly:

I use Arduino UNO as a controller. I found the servo drive connection diagram to the Arduino, the Arduino code, and the servo driver parameter settings on the @Lebois website. Thank you very much, my dear friend!

At the moment, I have not yet purchased a SimTools license (I will definitely buy it later) and am trying to use FlyPT with the DIRT 3 game. The platform moves, but there are some problems, such as uncontrolled sharp rotation of the drives during platform operation (I will upload a video a little later). I understand that I need to configure filters, but I have not yet figured out all the FlyPT program settings.

After setting up adequate platform movement, I am going to install the chair and the Moza R5 kit.

I would like to note a significant drawback of worm gear drives - this is a "knock" (noise, impact) when changing the direction of rotation of the servomotor. This happens due to play in the gearbox engagement. At the moment, I do not know how to reduce this "knock". Has anyone managed to solve this problem?

Nice work! The knocks caused by the backlash of the gear will hopefully disappear when there is enough weight on the rig to ensure that the gear is always biased in the same direction.

Until you got 2g+

To test the reduction of knocking caused by backlash in the gears, I loaded a platform weighing ~ 130 kg (me and my girlfriend). The sound has become a little quieter, but still significant.

What do you mean?

After the first test, I had to install filters: Roll, Pitch, Heave = EMALP(VALUE; 200.00)

It is very difficult to stay on the platform without these filters!
