The SimFeedback-AC DIY Motion Simulator thread

[sjb266]

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..

Yeah, I think I'll try to find a quick and dirty fix asap. Keep it cheap. If I don't like it's not as painful, to switch/build something else. I'm just worried about going down the rabbit hole. Then ultimately starting over anyways.

Have osr make you adaptor plates to fit the stx 100

 

[sn4il]

I had terrible luck with a roll of black inland pla. Hopefully it was just that roll because i got a few others.

I only used White & Egyptian Blue with these settings on Flashforge Creator Pro:

I’m on holiday for three weeks in beautiful South Africa, but I miss my SFX100 motion rig.. that’s how good it is.

I'm leaving for vacation/holiday tomorrow and I feel the same!

Especially after achieving back-to-back wins in iRacing earlier this week, which I never thought would ever happen in my sim racing career. Prior to those two wins, I only had 3 other road wins and the most recent was more than 4 months ago.

Enjoy South Africa, my friend!

 

[Hendra Chandra]

is there anyone in here willing to build the SFX-100 and sell for me?
I dont think I can DIY for myself because of the timing and shipping with different country. Someone in here would have resources to do so. Please do contact me

 

[minderacer]

I think I've come up with a plan, to buy 50*100 25 series extrusion and exchange them for the 50*50 bottom rails. This should give me more strength in the frame (with added supports) and allow me to lower my seat. Give me more surface area to mount the sfx-100. Then I can use the 50*50 as uprights for a monitor stand in case the monitor starts to shake to death. Who runs with there monitors mounted to the rig? I noticed Saxxon did anyone else?

Now I'll have to figure out how to get the wheel lower so ergonomically it for me

You're right I should she ask OSR about a custom mount .I'm sure they'd like to add it as an option.

Although that would be nice, I think fulfilling a request like that is against the terms of use.

How about just the 3d printing then?

 

[ScottSonder]

@ScottSonder I wouldn't worry yet about the profiles. Mine took a full month to get to me after payment. Shipping number was the same as yours, no activity for ages.

It's just the way it is with them. After a month, then worry. No one here has NOT received them, just takes a whiiiiiiiiiiille.

Thank you, Anton. Sometimes a story of a similar situation is all that's needed. The anxiousness in getting the motion rig completed is real.

Which series should I watch out for you in, Dave?

Must be a fun one in the SFX.

3d printing is fine I got one using Anycubic i3 mega.

 

[pass-low]

i've order another 40 and sent a message explaining i need the "right hand photo" and linked to the photo in this thread and wrote i got a bad batch and have given my order numbers. we'll see what happens

DHL man has just delivered me 40 "correct" inserts, happy days! (had to pay for them no feedback from Kinetik)
onwards with the project.

 

[Antracing]

This may have been answered already, but just in case, here is a free fix for the issue with the Rift headphones.

I had this the other week and even though my rift was 3 years old and really well used oculus replaced it with a new one.

 

[ScottSonder]

Grats pass-low, messed up that was a second order but promising they will provide the correct ones if provided the information.


I have another question quite off-topic from current threads that I haven't seen posted much. Pets. Does anyone have a curious cat? Now that I'm getting closer to a completed build, I'm wondering what I should do here. I'll be racing in VR, so I'm really worried about my lil' girl. I've never tried to lock her out from anywhere, but I could make the basement off limits I suppose.

Yesterday I donated via the donate button in the SimFeedback software, but today it got refunded, without any message why it was refunded.

Anyone perhaps know why ?

It's because you didn't donate enough. Donate at least 20-30 euros. Some people here have donated over 100 euros.

 

[JohnnyV]

Thanks for your reply.

I donated as much as I could, after buying all the sfx100 parts.
A man has got to eat

I’ll save up and donate a larger amount.

 

[Antracing]

I could do with some help, If I try to turn up the settings any more than around 0.68 overall I get a really bad "bouncing" effect under hard braking. (iracing) I cannot pin down what setting is causing it.
I've tried looking at the red bars live but still cannot see which effect would cause it. Its a shame as with the other settings so low the overall effect is not so good.
Its so bad with hard braking it makes my vision go bad, light braking is ok - but you dont stop in time

To clarify i use vr and its hard to see the live effects on a screen in vr.

 

[BluePotato00]

Skip Barber at Summit Point this week. Also managed a 2nd place in the series this morning. All cars are amazing in the motion rig, but to be honest, the Dallara F3 and Formula Renault 3.5 are the most exciting open-wheelers in the motion rig with the formula preset that was shared on Discord. Maybe I just need a better preset for the Skip Barber (or the patience to work through all the settings and build my own).

 

[minderacer]

The Musami GFS8-100100-250 is doable for sure with work...however the Inserts as i see it, would need to be done By them, Im not sure if getting them centered is possible

View attachment 296143

So I was playing around with a rig designing software, stumbled across this! Maytec makes this interesting "The Telescopic System".
http://www.maytec.com.de/index.php?id=80&L=1
I think the 80X80 would work but would need to develop/design a new slide, which shouldn't be hard sense they're designed for 40 series extrusion the slide through.. This would make the actuators a little more compact too. The software claims that they come in at $24 per 250mm.

 

[Furnace Inferno]

So minor speed bump, I have no hex keys that fit the thread inserts, what’s the exact size? I’ve got lots just too small and one bigger!
