Issue with hot end/tip

    1. my tip is blocked, so I tried to remove the tip. Heated the tip to 220. But it's so tight that that I am afraid to break it.

    2. one of the screws (left side) that hole the hot end to the the traveling z . Is loose. Is it supposedly loose ( because of the auto leveling) or should I tighten it?

    Nozzle temperature up to 260, and then unclog the nozzle with a needle, if still can not use, directly change the nozzle
