jonbonne 0 Posted May 31, 2017 in Bad printing layers (edited) So I've had a small issue just recently with my Ultimaker Original+ printer. I'm printing with ABS at ~240C and heated bed at 100C. The print starts fine and goes well until about ~3-4 centimeters up. At this point, it looks as if the nozzle is clogged or something as the material begins extruding non-consistently and spit-sputter stringy... but after about 4-5mm of this behavior the extrusion returns to normal, the nozzle begins extruding smooth and consistent again and the rest of the print completes satisfactory as long as the print-product doesn't break at those weak layers (which it usually does). My questions are what are the causes of this phenomena? Why would the nozzle behave like it's clogged 4-5mm consistently at around 3-4cm above the build plate then just return to normal operation? Would insulating the print volume help this? Any other suggestions or pointers? Thanks! Edited May 31, 2017 by Guest Share this post Link to post Share on other sites
