    That's the thing, yes. I found that even 0.1uF took out almost all the jitters but up to 100uF is good, 6.3V or more.
    I'm that HeaterMeter guy what ruins everybody's free time.

    All I could find was 470uf 35V. I'll give it a try

    470uf 35V did not make any difference!

    I'll go to the regular shop when it opens tomorrow and get 47uf and 100uf 10V and 25V.

    If it doesn't work I'll try Ralph booster!

    If the 470uF capacitor didn't make a difference, a lower value one probably isn't going to work any better. I'm not entirely sure why they vibrate though, so maybe there's more magic in a different cap that could be more beneficial.

    I'll try a different mg90 today and the bc337/10k booster.

    Update later today...

    The servo I was using was a MG90d (ordered from digikey, it said it was a mg90s, but they shipped the d)

    I bought a MG90S at the shop near my place and it was moving randomly. I installed the capacitor and now it's working great!

    Only problem is I think it's a counterfeit because it doesn't fit properly in my 3d printer damper. The mg90d was a perfect fit. The 3d print is made for mg90 and mg90s. So it should fit properly in it.

    So everything except the fit is working perfectly!

    Can't wait to give this a try in a month when there will be less snow out here!

    Thanks again for helping me through all of this and creating this awesome tool.

    Cheers
