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..

I actually think those occhie straps are better than springs......

Hmmmmm........

Hi all, totally new to the SFX-100 - 3d printing parts and ordering all this past week. I have the extrusion and the servo motors ordered. However the I am having a bugger of a time trying to order these parts. Does anyone have someone other than NTL Bearings where I can get these parts reasonably priced? I am looking for a single source rather than muliple to save shipping charges to Canada.

- Precision Hollow Shaft 30-20-270 30mm diameter - 20mm Bore - 270mm Length Bevel on both ends
- 1605 Ball screw and Nut - Length 250mm Machined
- LMEK30UU(30x47x68) Linear bearing
- Coupling-30-40-10x16 Diameter-30mm Length 40mm
- FK12 Ball Screw Support

Really appreciate your help! - I want to have everything at least ordered to make sure I just have to sit back and wait for the parts.

 

[sberns]

Also in Canada. If I was ordering again, I would still consider NTL bearings for all of that stuff except the 1605 Ballscrew which I would order from banggood.com. I don’t think you’ll beat that value and banggood’s ball screw had worked well for many others.

 

[Michael Labonte]

Link to the banggood ball screw? Thx

 

[sberns]

I believe it’s https://m.banggood.com/250mm-Ball-S...e-Ballnut-for-CNC-p-1001627.html?rmmds=search

I've had intermittent audio interruptions for a few weeks that seemed to coincide with a shader patch update (AC) so I put the issue down to new audio options, and investigated accordingly with no success. I'm busy light-modding a few tracks at the moment which involves lots of testing, and I noticed I wasn't getting any cut-outs when the motion rig wasn't active.

Long story short, a ferrite core added at either end of the Arduino USB cable and at each end of the HDMI between my PC and amp solved the problem.

Moral: ferrite cores rock. Try them first for any anomalies and you might save yourself a whole bunch of time.

 

[Michael Labonte]

Just ordered the equipment from NTL bearings. Only thing I have left to order are the bolts and 90 degree attachments to my current rig. It will be sometime before I build an aluminum extrusion cockpit, but it is on the agenda. I will get things working with my existing wooden platform as its pretty easy to just install with l brackets and lag bolts into wood.

Having serious warping problems with the PETG filament. So I´d build myself the Prusa Lack cabinet.
Pretty fun actually and I´m going to do some test prints after the weekend.
Luckily I´m in no hurry. Long waiting time for both the DD2 or the Simucube 2 (hoping for some serious reviews soon so I can make up my mind). Can´t order a rig before I have choosen a wheel setup.
Are where any Swedes what are planning of building a IKEA Lack cabinett? I´ve got two sets of plexiglas left over since I had to buy a big sheet of plexi and had it cut out.

enclosure your printer bed heated to 100 degrees, Nozzle 235 degrees then you get minimum warping with Petg but it is a little there

 

[Flag Ghost]

I tried an enclosure with PetG but didn't see any appreciable warp reduction unfortunately.

It’s either 2 of the controllers or the cabling segment up to the motor connection.. i checked and it was not the coupling. I used one of the working controllers/servo to move one faulty actuator and it worked fine (for a moment I was pretty scared that it were the motors). Next test is to de-rack and redo the cabling to use one the alleged faulty controllers into one working setup, keeping fingers crossed for it to be just be some internal damaged cable...

Follow-up to this troubleshooting. Issue was solved when I rearranged the cabling, not sure if EMI related but when I split the cabling in 2 pairs, grouping 4 in one side up to the rack and 4 on the other side everything moved smoothly!

As already had received my Pyronius board, couldn’t resist and sprinted to get all up and running today. I just finished my first session and what can I say... this is the best (by far) experience I had with a moving sim!

Can’t thank enough Saxxon and all the team for this authentic marvel. What a fine piece of engineered machinery, works like a charm! Thank you!!

PETG sux... Print the sliders in PETG (shouldn't warp at that footprint) and the rest in PLA - done!

I would do the opposite. Print the sliders in PLA as it’s a harder material and slides easier. Everything else in PETG as it is less brittle and handles bolts and tension better.

Nicely packaged @HoiHman thanks for your effort!
Beautiful product, well done @Pyronious !

UK SFX100 boards should get shipped to builders on Monday

 

[Dave_6]

Well my stuff from Kinetic showed up yesterday, which is much quicker than I was expecting (less than two weeks since I ordered it). What to order next lol.

I already have one of the SFX-100 Shields too; what does that eliminate off the shopping list?

Thanks!!!

P1 X rig ordered, DDW wheel on its way for the beginning of July, new rim arrived last week and new handbrake and seq shifter arrived a couple of days ago..........it would be churlish not to

Profile ordered ooops just fell into the basket dear

 

[Scoops]

And now name added to the second group buy for the shield here in case anyone has missed it starting up

[Phil Gravett]

Well this thread has started something

3D printer purchased - Got myself an Ender 3 Pro, which I have built and up and printing ok I think , lots to learn though with this 3d printing, when I get a couple of decent prints under my belt I’ll make a start on the bits for the Sim and start acquiring the parts for the rest of the kit.

Just need to keep it all secret from the wife
