    Hello everybody, this is my first post ever in this forum, so I hope I'm not breaking any rules.
    This january I decided to build a racing rig mostly out of scrapped parts with my dad and i think the structure came out pretty good.

    The problem is that I cannot get the Rotary Encoder to work reliably. It misses steps and I cannot figure out why.

    This is the encoder I bought off of Amazon.
    I used this guide as a reference
    Part 1:
    Part 2:

    I'm able to calibrate the wheel by disconnecting the z-index wire manually and by wiggling the wheel back and forth like he does in the video. The DC motor also works, it's just the Encoder who's unreliable.

    I tried doing as someone suggested in this forum and I pulled the AB phases high with two 10k resistors. Without them the encoder doesn't register at all, so it's better than nothing I guess...

    I'lll add some pictures of the wiring if your interested:

    I know the ground wire attached to the negative of the arduino shouldn't be there, but it doesn't seem to make a difference, keeps missing steps :(
    I put it there just to try something.

    Do you think my encoder is defective? Maybe I'm missing something obvious. I just want this project to work!
    Thanks in advance for any help I may receive
