    hey, are you using a capacitor at the pin of the a/d. ? I used to use a 1 or 2 microfarad that smoothed the input reading and didn't much slow the change of v.

    I'm using 0.1uF directly at the pin, but I could add 1.0uF and see if that improves things.

    But as Richard said in the other thread, an ADC variance of 1-2 is pretty much impossible to get rid of. I was able to get it down to 1, sometimes 2, but that extra cap isn'T gonna hurt either way.
    My Creality Ender 3 S1 Plus is a giant paperweight that can't even be used as a boat anchor, cause I'd be fined for polluting our waterways with electronic devices.

    Not as dumb as yesterday, but stupider than tomorrow!
