Nice motion Carl, no big throws and swings, it's just enough. Nice work.

Thanks Prodigy.

I found if you put too much motion in it tends to detract from the gaming experience and you end up adjusting your driving style to avoid being thrown from side to side in chicanes etc. Not so bad if you want to learn to drive like Jenson Button but if your aggressive on the racing line and kerbs it can be off-putting. I think mine is using at max approximately 100mm of the 150 available. I also have smoothing and spike filters running in the background on each axis. I would probably increase it for flight sims as the motion forces generated are much more subtle but when the motion is coming on quick and fast as it does in driving games its best to throttle it back a little.

Hi nclabs, a little collaboration would be great. I'm keen to hear your experience with the scn6's and very much interested to see what you built. PM sent.

Here is the basic design and dimensions of all the main mechanical components that go toward my platform build
2737
28232825
These images show the platforms before the upgrade coming together, notice the single plate base and position of the pivot
I widened the base front and back by adding the out-riggers. I discovered the need for widening the position of the feet when I started testing my old wiper motors... it was not very stable at all.

Here are the components I made to mount my scn6's

Here is a sketch of the articulated pneumatic mounts I used to attach the drive to the base

Here I have shown the general geometry and distances relating to pivot point and drive connections between base and platform.

Managed to persuade me testing a new math setup

I think I might remove the safety limiter tomorrow from the scn6's to maximise longitudinal G and see what 150mm of travel feels like. Im only using about 100mm at the moment.

First job on my electrics was to build a housing for the usb/rs485 converters. I used up some old 3 pin xlr chassis mounting sockets as an isolate point.
2800
I then fitted the converters, drive cards and soldered everything up
28022803280528062807
You will notice that the drive cards are very close to each other in my first attempt. This was a mistake I made and you will see that they are now sited outside the psu case and very well spaced indeed.They get very warm very quick if too close to each other but fortunately I spotted this before any damage was caused. Beware if like me you like to tightly package things. It does tell you in the user manual to space them carefully but unfortunately I missed it. Here is how they are now.
