Over extrusion?

Recommended Posts

Hi, I have been having issues for some time now with my UM2+. I use S3d for my slicing. I have had what seems to be over extrusion issues and surface defects that I just cant get to the bottom of. I have tried adjusting all the settings in S3d that are supposed to help and even tried to reset the steps in the firmware. Currently the firmware is reset. I have measured the filament diameter in several places and taken its average size and tried to see when the blobs/zits appear but I can never tell for certain if they are at the beginning or end of a layer. The cube is printed on 95% extrusion rate. Should I ignore the figures and just keep reducing the extrusion multyplyer? Any suggestions would be appreciated as I have got a bit lost now

I don't know about S3D slicer well but... as far as I know, it can be caused by retraction before outer wall printing or layer change.
