    I'd be more worried by the fact that signal swings negative and not positive :-)
    Don't worry though, it looks like you have the input coupling set to AC on the scope. Set it to DC and try again.

    Thanks! I thought of rechecking my stuff a Nth time yesterday and noticed the coupling too.

    All is well in the world.

    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!

    Got this from AllAboutCircuits. First time I hear about a MC14490, Hex Contact Bounce Eliminator:




    Too bad it's in multiples of 6 pins. It would be perfect if it was 8; that way I could have 2 ICs running alongside MCP23017 I/O Expanders with no waste.
