    I do have, but the printer isn't in it at present while I'm working on it. I usually drop the bed temp down when the printer's in there.

      From what I have read ABS really needs a heated enclosure BUT I don't know if that is related to your problem.

        @alankilian said in Problem with rear side of Test Cube:

        1/ Do you see filament extruding on the back cornets?
        2/ Do you hear your extruder struggling/clicking when that happens?
        3/ Can you rotate the cube 180-degrees to see if it then happens on the front?
        4/Can you rotate the entire printer 180-degrees to see if it changes due to airflow?
        5/Do you have an enclosure?

        1/ Back cornets?
        2/No clicking, extruding nicely when I move it up and extrude some filament.
        3/I should have mentioned that I had done that, it still happens on the rear (mainly)
        4/The pinter is on a wheeled trolley, I have tried that. Ambient temp is 18.4C atm.

          Yes, I found that out a while ago, which is why I made the one in the pic. It is made from 50mm expanded foam, coated with thin fiberglass panels. The material came from an old coolroom.

            But the issue remains. Any other helpful suggestions, they've been good so far?

              Instead of printing a cube can you create a model of a disc, say, 50 mm in diameter and 5 mm thick?

              If you can print it using you normal settings.

                  Sorry Fredrick, but my modelling capability is V low. Could you please suggest a model from thingiverse or somewhere?

                    Here you go.

                    Slice it normally but keep the layer cooling fan(s) off.

                                The disk is printing at 30 mm/s. It will probably take about 20mins more.
