First post here...
Having a few issues with Ultimaker 2 extended not extruding filament consistently.
I have attached a few images which will probably show you the issue straight away.
It seems that the extruder is not applying the filament to the bed consistently. I have cleaned the nozzle out using the atomic cleaning method and also tried using a different filament. For this particular print I have been using the UM2E Colourfabb PLA setting that we have been using since we had the printer. I have also printed out a Ultimaker test robot which came out fine and the first layer went down as normal.
If you have any thoughts on what the issue could be, that would be great.
