Hi, Relative new on 3d printing and started to do some print with TPU 95A. Worked ok and swished to tough PLA did some print that was ok then switched back to TPU 95A. Suddenly last layer wasn't looking too good, see picture. So redid the print, then suddenly it said that there was no filament loading but clearly there is. Tried to unload and load and now it won't extrude when loading? Loaded with tough TPU and it extrude when loading so do not think it is clogged. Any advice on what to do?
