MMU error during print  

MMU error during print

Dear comunity,

some weeks ago I got the assembly kit for the upgrade to MK3S and MMU2S. Now I tried to print some parts. Some of them were good but I really have troubles with this sheep.

I downloaded it at https://www.thingiverse.com/thing:2954475 , imported the stl-files to the slicer. Used the “0.15mm Soluble interface” mode

1^st try:

1^st filament: PLA galaxy black

2^nd: PLA white

3^rd: PLA pink

4^th: PLA grey (not selected)

5^th: PVA

first 10mm were fine, then the printer used the third filament instead of the second one.

Then he chaned to the 4^th, which I didn’t selected in the slicer and finished it in grey (result is on the first picture).

2^nd try:

Update of the firmware, slicer, a.s.o.

1^st filament: PLA galaxy black

2^nd: PLA white

3^rd: PLA pink

4^th: empty

5^th: PVA

20 mm were printed as defined (some MMU errors during the print, but fine)

After another MMU-error at approx. 20mm he used the pink and black for the ears and head correctly, but instead of white he used the pink filament too. The punk-sheep is nice, but not that what I wanted.

What did I do wrong????
