Thanks... already ordered one so I’ll try it.. I have also ground both ends of that shielded cable but that didn’t help.

Ok so this helped. I have ungrounded both ends and it was better but not perfect. Then I replaced cable for 18awg and now it runs nice and stable. Thank you. I really appreciate your help. Can you also explain why making it better actually made it worst.. I don’t get itmartyscncgarage wrote: ↑Sun May 02, 2021 1:50 pmUnground both end.LenelyWolf wrote: ↑Sun May 02, 2021 1:47 pmThanks... already ordered one so I’ll try it..

Also try just a pair of 18gauge wires. You have nothing to lose while you are waiting for the cap
I have inspected the cable by taking it apart and didn’t see any visible damage. Well at least it is fixed. Should I still install that capacitor?polaraligned wrote: ↑Sun May 02, 2021 6:12 pm Sounds like you had a bad wire. Maybe the wire had some corrosion and was not making a good connection.
(.5mm) 24 awg is a bit small and delicate. The added capacitance from increasing the size is trivial.
I wouldn't bother.LenelyWolf wrote: ↑Sun May 02, 2021 6:33 pm I have inspected the cable by taking it apart and didn’t see any visible damage. Well at least it is fixed. Should I still install that capacitor?
