Extrude only the first filament, the other 4 don't
Advice, please. I have an MK3S with an MMU2S. Loading and unloading work well for all five filaments, but only the first filament prints properly. The other filaments load to the nozzle but do not extrude. At the second layer, the first filament prints correctly, but the others do not extrude again. What could be the issue? Thank you for your assistance!

Try cleaning the nozzle and checking the PTFE tube for blockages. If residual filaments from the first filament are preventing other filaments from extruding properly, increase the discharge volume in the PrusaSlicer to ensure complete material transfer.
