Extrusion problem
Hi!
I have recently upgraded Mk2 to MK2S. After assebly and callibration it seems fine. A made prusa logo from the SD and someting else, rather simple. Then I have tried to print treefrog included on the SD. This is how it look after the print was finished.
Quite a lot of stringing and missing material it top part. Overall wall quality (the back of this frog) seems good. I thing the problem appears in places where very short extrusion/retract take place. I have printed some other models and problem was very similar. Some parts were missing, with holes like in this frog.
Filament - Silver PLA that came with MK2 kit. I have also tried other PLA (Spectrum FIlaments) and the same problem. Any ideas? I have not calibrated extruder after the upgrade to MK2S. Is that possible that this might be the case?

Problem resolved. It turn out that I've had 7,7mm of underextrusion 😮
