Please note that the FS-lever has to be printed in black PETG. The color of the extruder plastic parts can be different, but the tiny FS-lever has to be in black.
I had it printed in Prusa Green Gold PETG and I got continuous ‘Unloading filament’ issues due to this.
I then used a permanent BLACK marker to color only that part and that fixed my issues.
make sure to print the “fs_lever“ in BLACK, as stated by Prusa (https://help.prusa3d.com/en/article/ir-f...)

I think you missed a step here: Secure the M5x10 screws :-)
