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..

Can someone confirm what main wire goes where please?
The motor has L1, L2 and L3.
Which one does the live go to, the neutral go to and I guess the earth just goes to the body?

If you look at the wiring of mine I posted for UK wiring then it will make sense. You only use the top two but I can’t remember what they are labeled. Live at the top, neutral one below and the 3rd one empty. Ground under the spare screw on the metal chassis where the ground for the motor wire attaches under the other screw.

[QUOTE = "ThugUK, post: 2962860, miembro: 212808"] ¿Puede alguien confirmar qué cable principal va a donde quiera?

¿A quién se dirige el live, al neutral y supongo que la tierra simplemente va al cuerpo? [/ QUOTE]

Excellent thanks.
I am hoping to run it off one plug, so thought of bringing a single cable in, splitting it into 2 and then 2 again with connector blocks, then feeding each motor.
An issue you can foresee with this idea?

 

[Black_rat]

They were wrapped in paper too, best package so far apart from the Creality 3D printer, now that was the zen of all packing...

 

[iigator]

seeing that photo ... I think it is indifferent what is the phase and what is the neutral ... what do you think?

 

[sn4il]

Stop using NTL guys... they only come with problems and they are not the best priced.
You can find all you want on AliExpress and you can check dimensions with sellers.

These are very nice, they come with grease nipples

 

[niko911]

I’ve recieved my package from NTL yesterday and have measured the ballbearings.
44 mm...(36 mm the smaller part).
So I guess that I will have some trouble too...
The best solution would be if the constructor of the slider would be so kind and make a version.2 (make the 30 mm hole 2 mm deeper) or make the original CAD-file availible (can’t make a body from the meshed STL-file). I’m an absolute beginner in Fusion 360, but would gladly make a go for it.

I don't think there's chance that a modified version will be made available, it would take away 2 hole mm of 3D printed material in a critical part without this being tested. Better add a spacer on top or get the right ballbearings instead. You have to try first to see if there's enough clearance for the extra 2mm

 

[HoiHman]

@iigator

See how i wired it in my video

 

[Pyronious]

Hope mine come packed like that after seeing some of the earlier horror stories.

That's what mine looked like when they arrived. They were a bit dirty inside the profiles, but otherwise were in good shape.

Ordered on Feb 21, 2019
Delivered (to west coast US) on March 7, 2019 (14 days)

 

[niko911]

I’m not sure of that Hoihman. Think that adding a 2 mm spacer would be much more brittle than removing 2 mm in the hole (if the ball bearing is flush to the material in the hole, it wouldn’t be a constructional problem?). Another solution - adding 2 mm on the original slider (version.3 ;-)?

 

[BluePotato00]

Guys, do you think going with 1 meter DB25 cables could cause any issues?

In my opinion, no. That's still quite short and those big cables are decently shielded. I use 3ft cables with no issues.

Great. Thanks for letting me know

Convert your mesh to brep and you will be able to modify the file.
Removing 2mm in depth will be super easy, just make a cylinder of the same slider hole diameter and extrude it to the right height to remove that extra 2mm

Going to ask because my search is coming up blank.
I thought I read in here somewhere where someone was using a single E-STOP button to control their SFX and an OSW Mige wheel via an electrical device. I suspect it's as simple as a relay related solution but a proven solution would be nice. Any help would be appreciated.
TIA

Maybe it was me, not sure, but I am using a remote control switch that switches off all mains power to my rig. This includes the OSW and the SFX100. I only intend to use this if things go really wrong. The E-Stop is still there though. It’s just that if something starts to smell weird or if smoke appears I’d like to be able to switch off all AC power immediately from my rig.

Thanks for the reply. It wasn't that, it was definitely via an e-stop button.
