Today I tried to modify the reference voltage (VREF) of my a4988 from OYOSTEPPER. but the potentiometer was adjusted too high so I don't know how to re-set it to 1.2V.

I got up to 7,000 and realization of my own mortality kicked in. There's no way I am going to watch, let alone rewatch, that many titles in my life time. I've started picking and selling off portions my collection because of it - like films that have been sitting on my shelf 10-20 years unwatched and films I never plan to rewatch again.
