The SimFeedback-AC DIY Motion Simulator thread

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!

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..

Doesn't work in safe mode either. Here is a screen shot showing SimFeedbackStart running, but nothing in the taskbar.

It looks like the issue is with remove_blocking. I tried it on another computer and got the prompt when I ran remove_blocking.bat and the simfeedback program ran fine on that computer. remove_blocking will not run on my simracing computer. I don't know what the issue might be, but have tried safe mode and turned off windows defender in case it was blocking it. Any suggestions?

I finally got it working!! I reset all windows security/notification settings back to default and was able to get the remove_blocking.bat to successfully run. It's working great except for oval racing in iracing. Works perfect on road courses, but is not working on paved and dirt ovals. Not sure if this is a known thing or not. Thanks for the help!

Sure, happy to help! The 8020 setup was totally fun to do. I ordered the parts and designed this myself, and it wasn't that expensive. *maybe* $500 or a bit less to do this.

It's based on 4080 profiles and the 40-series. Depth of the main rails is 1525mm. Width between the rails is 535mm, enough to clear the NLR v3 and mount it as low as possible between the rails. The main uprights on the wheel deck are 600mm. You'll need:

2 ea 4080 rails, 1525mm,
4 ea 4040 square profiles, 610mm, for seat and pedal mounts.
6 ea 4080 "light" profiles, 600mm, for uprights, cross braces, and aux mounts
(some of these will be cut during installation)
1 ea 4040 square profile, 1219mm (4 ft), cut during installation for wheel deck supports.
4 4040 dynamic joints
4 5-hole, 40 series corner braces
approximately 250 t-slot nuts (yes, you need that many)
approximately 100 corner brackets
~250 m8 x 16mm bolts
~25 m8 x 20mm bolts
other misc hardware

I probably forgot some stuff, but that's the key 8020 bits, above. Your rig looks AMAZING, really, really well done! I'd love to try it out sometime, seriously.

If you're ever in Albuquerque, let me know, and we can try things out and compare notes.

Thanks!

When you refer to square profiles:

By light you mean this:

And square is this?

I don't get this one: "approximately 100 corner brackets" :)

I looked hard and see only like 20 in use. They are possibly on the wheeldeck, but it's still hard to imagine this many :). Would you have by any chance more photos of the wheel deck in front, which is not very visible from these photos you already sent?

Also what really suprised me is price, maybe you have some really cheap supplier in US.

But 1 corner bracket in shop where I buy aluminium profiles is like 3 EUR. Meter of 4040 light is like 10 EUR. They don't have eshop, so I would need to quote them directly, but I think this would be much more than 500 EUR with these prices, I guess it will be more like 1000 - 1500 EUR, anybody got recommendation for cheap aluminium profiles in Europe?

Long road to Albuquerque, but if I'm ever in the area, I'll let you know :) You're also welcome if you ever wanted to visit Prague :).

Just actuators themselves can use 16 brackets (4x each actuator).
The frame itself may require 1 or 2 either side of each joint (the square frame, 2x seat mounts, the wheel mount the 2 pedal mounts plus cross sections, the gearstick mount etc), so I can see there are quite a few angle brackets required. Ok maybe not 100, but certainly more than 50-75

Yes, that's exactly the difference between regular and "light" profile. The light would probably work for everything, honestly. The 8020 stuff is quite strong.

Next time I move the rig, I'll get a picture of the front (the rubber pads on the bottom of the feet prevent this from moving during operation, but also prevent me from moving the rig).

It's really easy to use 4 corner brackets in a single 4080 90-degree joint. 2 on each side to brace. If you double up key joints, you'll quickly get to several dozen with any kind of accessories mounted. However, I did overestimate, for sure. I just counted, and I have something like 55 corner brackets on my rig. I bought the 8020 profile off eBay, and here in the US shipping was reasonable. My total cost for the profile was $468. Corner brackets were $18 for ten off Amazon. I had the metric nuts, and ordered 200 slot nuts, which somehow wasn't enough.

I've been avoiding adding up the cost, I'm married. Looks like $600 is closer to the mark for my cost, but you may not have things like metric nuts already. It's starting to look like an EU buyer may be just as well off picking up a GT1 or P1x rig from Sim-Lab.

Good luck, having tons of fun with my rig. Been tuning the motion in Simtools, lots of options. Feels fantastic. Today, I'll go after Asseto Corsa profile (yesterday was Project Cars 2).

Is that a HOTAS mount in front of the seat ?

If so how do you mount the throttle and deal with pedal changes for transitioning between flying and racing ?

Just starting out on my build and have all the parts for the SFX100 ready and the printer running, for the actual frame I've ordered a P1-X to use as a starting point - just trying to figure out the best way to mount everything for a dual purpose rig.

Yes, that's a Thrustmaster HOTAS. Custom underseat mount. It's bent slightly to angle the stick away from the chair.

I do mainly space sims (Eve Valkyre, etc) so don't really use the pedals. I've got a little app that allows the throttle and clutch to serve as rudder pedals if I wanted, but haven't used it much. The throttle is on a removable mount that screws into the 4080 profile on the left side of the rig.

55 sounds more reasonable, thanks :). I'll look around for cheaper supplier, but I'm not sure, I'll find any. It might be cheaper to go Sim-Lab rig, but I'll probably need wider base, so I'll have to do it completely custom.

I'll wait little bit, until I really build SFX, with 8020, everything is super fast. Attaching custom peripheries to N1 is quite hell to do :) going to 8020 will save me lot of nerves for sure and maybe also money in the end :)

PS. Your monitor mount looks amazing, well done as usual :thumbsup:

Any recommendations for blowers to attach to my rig ? - it's starting to warm up in my shed ( flat roof and dark brown garage door ) and I need something to cool me down... would also like to hook them up to simfeedback ( or other tactile software ) in the future.

... Amazon uk would be my shop of choice

There are cheap Chinese Dyson Blade looki-likee knock-offs on eBay that are surprisingly good. No danger of accidentally poking your todger into the rotating blades either, depending what you get up to in VR... :whistling:
