    pictures and details would help :-)

    Just saying: 'print goes wrong halfway' doesn't really help :-)

    Kinda like phoning a doctor up and saying: 'I'm ill - fix me'.
    Detail is king !

    This question/problem may be related to the defective model from another post. I guess we'll see what comes of either one.

    looks like the firstlayer isn't sticking.

    What filament, what temperature, what speed for the first layer etc
    The thing about details is IMPORTANT.

    The images you've posted show a layer height of 0.4 mm and a nozzle diameter of 0.8 mm. These are unusual numbers unless you've modified your printer or it is configured for large high speed printing. I found on their web page that one can purchase the larger nozzles. Confirm the nozzle diameter you have and change the settings accordingly. You should not have a layer height more than seventy five percent of the nozzle diameter. For a 0.4 mm nozzle, the most common size, 0.3 would be the max layer height.

    If your nozzle is indeed 0.8 mm, the 0.4 mm layer height is acceptable.

    Check your nozzle and report back.

    I see the print speed is 80 mm per second. That's astonishingly fast in my opinion. Consider to slow it to 50 mm per second as a test.
