Recently I had anothere sever clog in the hot end of my Solidoodle 3D printer. I have cleared these before but this one proceeded to “ooze” ABS all around the extruder hot end. Due to the fact that mine is still the original unit encased in a type of “cement”- this was going to be some fun to clear. I opted for grabbing a new unit while I rebuild the old. Cheers!
