Hello all, I would like some assistance with a problem I am having with a PLA print, we have printed this model before with no problems, but recently I have tried to print the model and it fails and does not print correctly when printing the legs, the layers do not seem to be complete, I have tried everything I can think of. Temperature in the print room is ok and the material is Ultimaker PLA filament. The photo shows where the print failed firstly (left hand print) this is at 0.2mm layer height, I have tried to print many times and always fails at the same point, the right hand print is at 0.1mm layer it prints but the legs on the print are not forming correctly at the top. Any ideas?
