woo!
Just a tip I found from my first two rolls in my Nopo.
There's a wind-on knob, and a wind-back knob. Don't expect them to work the same as in regular cameras. I used the wind-on knob only for my first roll and thought it was finished when it tightened and I couldn't wind anymore after maybe 6 shots (24exp in a panowide should have given maybe 10-15 shots).
So what you need to do is loosen the wind-back knob to give some slack in the film and then wind on.
Same goes with rewinding, give some slack with the wind-on knob and then pull with the wind-back knob.
I also found my first film somewhat scratched, I'm sure that pulling it extremely tight without loosening the wind-back knob first contributed a lot to that, I'm a lot more hopeful for the next roll.
(I also got a whole heap of light leaks on my first roll, but it was a 40 year old FP4 from a bulk-loader so the leaks may have been on the film already. And I may have been playing with it and accidentally opened it before winding back, so I'm blaming them on me for now)
