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..

Will be supported in the upcoming multi controller release and is very handy if you need to work on your rig

If anyone does raise their rig to work on it then PLEASE remember to physically prop it up with stacks of porno mags, bricks, timber blocks etc.
During initial installation I was working under my raised rig (doing cable management, I think) when a random signal disconnection caused the whole thing to drop. I've no idea how much my combined P1, SFX, racing seat and sim hardware weighs but if I'd not been able to quickly extricate myself I'd have been trapped and possibly crushed to death.

On the positive side it rapidly cured my constipation.

Stay safe, kids.

Hello.
what is the tolerance for the aluminum profile?
250mm +/-

 

[metalnwood]

Hello.

250mm +/-

It doesnt matter too much but if you have got them from germany they will all be the same length and probably close. It wouldnt make any real difference if they were a few mm either side which should be well within any companies cutting ability.

 

[vulbas]

thank you @metalnwood
247mm it is good for exemple ?

You are definitely right @Mascot that why we have mentioned this in the disclaimer on the github page.




It have tested and the plugin can keep you rig up for hours in it's highest position,but always be safe and put a support under the rig which catches it in case the rig drops down for whatever reason.

This plugin is to raise your rig so you can put a support under it at it's highest position, not for lying under rig, trusting that nothing can happen with USB/Power supply/programm or even EMI.

So ALWAYS BE SAFE and with a couple of leftovers from my previous 80/20 rig, i created a couple of these



(that's a pretty big stag or p**no mags )

 

[metalnwood]

thank you @metalnwood

Yes, you won’t have any issues with that length. I think if you get to 240 you start to get close to having an issue

 

[metalnwood]

Thats nice Henk but I would use the porno mags... In this world of the internet wouldn't it be nice to be able to say one last time. Saved by the porno mags.

Ok thanks for your help

I’m curious as to any situation when you could say that.... Maybe my imagination is more limited than I once thought....

The mother of all SFX-100 3D prints. I was away for a few days on a business trip, and didn't want to lose the time I could be printing parts. I don't recommend this. Takes a full roll of filament and about 60 hours to complete. Any printer screw-up, and its all ruined.

I've got my printer dialed with over a 1000 hours of error-free printing, and only now would I trust a job like this to it unattended.

I like your style. Did the same with my Prusa i3 MK3. Was printing for a friend after successfully printing all my parts without a single failure, I thought 'what the heck' lets stuff that build plate!

Never trust 3d printer They catch fire especially with PLA. Error-fee printing has little to do with it. Most of the time it's caused by bad temp sensor or part coming lose off the bed and getting stock at hot end.

Does anyone have Sketchup files / drawings for the pieces of the build? Want to write some clear instructions that I'll share. Would be good to have some nice illustrations for the pieces if someone has already made them.

You mean like these? https://opensfx.com/build-process-sfx-100-actuator-assembly/

Perfect, just like this. Thanks. I'm feeling more confident about the build now.

Would still be interested in a CAD SketchUp file of the pieces to make an Ikea style build guide.

I am just getting started on my build and I have never owned/researched a 3d printer before although I could have used one LONG ago for several projects. I think I have finally worked it down to the i3 and the CR10S. Don't mind spending the money on the PRUSA but all the reviews indicate the CR10S prints just as well and trouble free as the i3 but for ~1/2 the price on sale. For those with some actual knowledge, can you please advise if there is a clear advantage for the i3, as it relates to a project like this, over the CR10S? Open to other options as well, but want to keep it under 1k for sure.

 

[ThugUK]

I think that they can all give good and bad results if not set up correctly.
I printed mine on a Creality Ender 2 (for £95) and had amazing results.
Not bad for a first ever effort of using a 3d printer.

I did replace my tarentulla with A ender 3 pro and super pleased with it. All my print for the sfx 100 have gone verry good.
I dont have alot of exp with 3d printing so it worked Nice out of the box.
From my exp i can recomend it for a cheap 3d printet
