SFX-100 possible EMI issues?

Hi. As the title says i suspect i am having EMI issues with my recently built SFX rig.

I finished the build about 1 month ago. And it was working fine at beginning.
But this week i noticed i am having issues with Fanatec CSW wheelbase and CSW pedals. Games does not react to steering input intermittently during gaming. Also sometimes throttle and brake are stuck in same position. Also confirmed through fanatec wheel property page is stops reading wheel position for a short while when servo motor and simfeedback is powered on (even without actuators moving).

It is not a complete USB disconnect problem as i cant see disconnects or warnings on windows event log. The problem last about 0.1 second to max of 1.5 second and appears at random time and intervals in all games when SFX-100 is on. When driving without motion platform powered i do not have any issues. Also only equipment having issues is my fanatec equipment. Other USB devices dont have issues. Other USB hardware i have connected are: WMR headset (HP reverb), arduino USB handbrake, keyboard, mouse, USB headphones. All 230V equipment is connected to same electrical outlet on the wall (Computer,Wheelbase,SFX servodrives,Monitor)

What have i done so far to solve the issue:
- I tried different USB cables for wheelbase connection and tried different USB ports on my computer. Also tried disconnect all non essential USB -> No change.
- Connecting the CSW pedals directly via USB instead of wheelbase connection seemed to help a bit. And now i have not noticed pedals input stuck but wheel is still unresponsive at times.
-Tried reroute cabling to make sure USB cables are as far as possible from motor wiring and not crossing power wires
-Ordered ferrites to install to USB cables (not yet arrived)
-Ordered another shielded USB A - USB B cable for wheelbase connection (not yet arrived)
-Tried wrapping alu foil around motors (maybe little less frequent wheel freezes or placebo effect?)
-Adding extra ground lead from rig to servodrive cage safe grounding point (no change)

My questions are as follows:

Should i rewire the motor power cables with shielded cables? (I was not smart enough to order my motors with shielded cables during purchase)

Can installing ferrite chokes to all USB cables help? (fanatec usb cables already have ferrites on both ends)

EMI filter install to network power inlet side of the AASD-15A servo drives?

https://www.mouser.fi/ProductDetail/Schaffner/FN2010-30-08?qs=Eu63EZxBwKL/R97nJquTkQ== this sufficient EMI filter?

Other ideas to solve the problem?

Picture of my rig in current state in attachment. I know the wiring is a mess because of constant rerouting when trying to find and solve the issue.

Do you use a usb hub? if so, it must have its own power source. Another tip is that all hardware is connected to the same ground point.

Yes!!!

No USB hub. All USB devices connected to Motherboard I/O
All hardware is connected to same ground point.

Follow up questions of shielded motor cables:

Is it enough to use shielded cable only motor Power cables?
Signal cables can left as it is?
Shielding has to Be grounded on both ends of The cable?

Yes, only the 4 wire power cable needs to be shielded. You can connect the shield on the servo drive side only , to avoid ground loops.

The encoder cable of the motor (with the db9 connector, is already shielded. No need to mess with it.

Ok. Thanks for advices.

Quick FYI. I am running the AASD servo drivers here and I have found adding the EMI filter cures most of the problems. I am in the US so I am getting my filters on either E-bay or Amazon.. They work amazingly well.

Thanks for replies.

Yes i think i will also add an EMI filter.

Update: Now i am pretty sure the biggest issue is the interference from the motors/motor cables. Today started also having issues with my VR headset tracking , this was something never happened before. When i took headset off and looked what`s going on i noticed my headset cable was leaning against the motor/actuator assy. After moving cable away from motor tracking was fine again.

So my next step is going to be to rewire the motor cables.

For the time being i can use the SFX mostly fine, if i make sure USB cables are as far as possible from the motor wires.

btw, Anyone have a video link how to disassemble/rewire the motors?
I think i have seen a video of rewiring the motors but could not find it with google search.

Thanks @Thanos. I should have guessed it was a video made by you.

Ordered some shielded cable today. Will update to this thread if my issues are gone after rewiring motor cables.
Also ordered an EMI filter. I think it doenst hurt to fit the filter too.
