The SimFeedback-AC DIY Motion Simulator thread

sjb266 · Sep 17, 2018

Hey guys. Thought I’d create a thread for those taking the plunge into this brilliant DIY project..
I will be starting mine soon and I know there are others thinking about it.. so feel free to share your knowledge and experiences so we can all enjoy this platform to its full potential. A huge thanks to the developers who have really knocked this one out of the park!

Website: https://opensfx.com/2019/02/20/welcome-to-our-new-site/

Github: https://github.com/SimFeedback/SimFeedback-AC-Servo/wiki

For all the internals for the actuator contact Amy - skye@ntl-bearing.com
She can supply everything you need. Just remind her you want the ends of the shafts chamfered and make sure she sends the right sized ball screw - we have had a couple of issues reported. She is very helpful though and the cost is pretty good.

Huge thanks to @RowanH for writing a comprehensive user guide which can be accessed here - https://www.rowanhick.com/sfx-100-build-and-running-guide

In addition, @anton_Chez has contributed a list of post numbers for some of the important settings etc..

Also make sure the worm screw is completely loosened so there is no tension on the coupling when sliding it on.

Yea I had it completely loose

hello
which bracket do you use to fix the aluminum profile 100 * 100 with a profile 40 * 80 ?

I used 40 x 80 corner brackets and printed 20mm spacers. I think the STL files are attached somewhere in the thread. If you can’t find them and you want them let me know.

Vincent Dimaio · May 22, 2019

ok thanks. i find the post

Nice to see you still poke your head into your 241 strong page thread, Simon.

So many different forums and places we dislcuss this, sometimes I forget about this thread that I couldn't take my eyes off for the longest time.

Ah yes well done.. I only posted the single 40mm spacer.... if you want to bigger 80mm x 40mm version let me know..

Moe Ballout · May 23, 2019

How far are you guys mounting your triple screen from the simlab p1? I like my screen pretty close I am assuming that is going to be an issue

RowanH · May 23, 2019

I'll take a photo of my setup later. You can get quite close it really depends on what safety margin if your rig moves crashing

Vincent Dimaio · May 23, 2019

I am looking for a person in European Union who would be able to print 3d parts for the SFX 100. contact me in MP
Thank you

I got mine done using 3dhubs. Worked out really well so far.

Moe Ballout · May 24, 2019

How long after donation do you get the expert license and discord info? I should be done tomorrow with the actuators and db cables will be here so it will be ready to put it all together. Can not wait to try it compared to my nlv v3 motion. Are people keeping the lfe kickers with the sfx? Or are they not needed? I run them in chassis mode at the moment.

Flex33 · May 24, 2019

Anyone have the Rift S yet and tried it with the motion sim? Curious how the inside tracking works with motion...

anton_Chez · May 24, 2019

I'd keep any tactile gear you have and make better use of it with choosing specific effects that the actuators won't give you or don't do so well. In other words, keep tactile for Speed and RPM effects. They add A LOT to the experience. Especially if you have nice units. @Moe Ballout

I was thinking to switching it from chassis mode to on the seat and pedals. I run 4 lfe kickers with a emotiva amp.

For Assetto Corsa users:
If any VR/motion users finds the 'Neck' settings totally incomprehensible in Content Manager then try these from a user on the Discord. I think they do a really good job of balancing environment movement and cockpit movement, especially keeping med-range/distant objects stable (similar to 'lock to horizon', and how our own vision works) while adding some cockpit/car shake.

ThugUK · May 24, 2019

I still need to find and install ‘neck’.

You don't need to install it, just activate it in CM.

anton_Chez · May 24, 2019

That's what I did @Moe Ballout. I removed 4 Aura Bass shakers in Chassis Mode and swapped them for the BK Mini LFE x 2, at the seat and pedals. I've now added a handful of Dayton Pucs for the seat but still nothing in a dedicated Chassis Mode and nothing with left / right separation.

I pretty much ONLY use RPM and Speed. Gives a great feeling of power on the throttle.
