Hy!
I'm having the same problem with my Ultimaker S5, at the end of each print a blob is made by the extruder. I looked in Cura for the extruder start GCode and end GCode and they are both empty like recommanded. I also looked at the GCode flavor and it is set to Griffin instead of Ultimaker 2. I changed it to see what would happen and when I put my USB key in my 3D printer it said the file had been sliced for an other model of printer, so I had to change it back to Griffin to be able to print again. I'm working with Cura 4.2.1.
Is there something else I can do to fix my ending blob problem?
Thanks in advance!
