Hi,

After installing MMU2S I was able to print some demo prints. Bud since some time the behaviour has changed. The calibration is started, the filament (PETG) is loaded and it creates bunch of filament on the side of the print area and then stops with red light flashing fast (the unload failed). 

Do you have any idea or experience with this?

Thanks a lot

Here's the page that explains LED error indications.  Rate of flash is significant.
