Hi, since some days I get an additional "blob" of material at the end of the print - see photos. So the print head is not immediately retracted at the end and some material is pressed out of the nozzle befor placing the print head at positon zero. No clue where it comes from and how to cure .... It can bee seen on the blueish photo on the right, on the two others on the left. Object size 8x3 mm without brim. Nd
