Help with SFX-100, started acting weird

[Pucis666]

I moved the whole rig to a different place in the room and since then it does this... It keeps randomly dropping down a bit, the video shows what the motor controllers are doing. Do you think its EMI or something else? No other equipment is affected in any way, just the SFX-100 itself :/ Any ideas?

Can't tell for sure from the video... are you sure the cables are shielded?

No they are not, just ordered shielded wire, will replace the originals. Weird, it was working fine for a year and now suddenly going mental

Are you using a shield or is it hand wired? If all drives are affected then the source has to be before them?

Yes I use the shield

Maybe a grounding issue? Different wall socket than earlier?

I think you just did it I started to think, what is different, and the only difference I was able to think of is a different extension lead, turns out the old one has surge and spike protection, I guess sometimes the stuff on extensions are actually true Need more testing, but so far seems much better. Still will change wires, cause I already ordered them

Edit.. Naah, after a bit of stability dropping again... ok, will wait for shielded cables and will go from there :/

Did you plug all USB devices back to the exact same USB ports on the PC as before? You might have a USB ground loop some where and changing the USB ports will result differently.

In any case, replacing with shielded cable is almost a must for any SFX100 rigs anyway, even if it may / may not fix this particular issue.

I think everything went back in the same ones, but yeah, the cables will be here tomorrow, will start with that and report the results

Update: So just received my shielded power cables, run few laps and left it standing in up position for half an hour, no drops anymore, so at this point I think the shielding was the cure. Thanks guys for your input, See you on track

Where did you buy the shielded cables?
