Made a short video here to visualize the problem:

I want to boot it from the reference disk, but it always does the shown.
The Floppy seems to seek, but then it doesn't seem to be happy anymore and just moves the readheads 3 times before booting into basic.
I tried to clean the heads, I exchanged the two electrolytic caps on the floppy with new ones. I reseated the flat flex cables, made sure there are steady 12V and 5V arriving at the diskdrive and lubed the mechanical parts.
Any Idea what could be wrong?
