Can you minimal move the gears?
You might need to break off the gear-fins from the center, without breaking them apart.
It's hard and it costs sometimes a bit more power.
I sometimes put it into silicone oil, top make the parts move easier, once they are disconnected.
Is NO gear moving, not even a bit?
After removing all the supports, I start stretching the holder of the vertical gears with a screwdriver. If that starts to move e.g. 0.5mm, I continue playing with it, making it move more and more, step by step.
