    Good adhesion except one corner

    Hello
    I have an Ender 3 Pro and i recently managed to ram my hotend into the printbed while trying to calibrate my bltouch z offset.
    since then in the lower left corner nothing wants to stick to the bed anymore.
    I have also switched around the buildplate but its still the same problem

    You are still printing too high, so further adjustment of Z offset is needed. Graphic for reference:

    If you still have curling in the corner, after perfecting first layer, then collision might have done some damage - could be either BLTouch or mechanics of the printer (axis alignment, X/Y carriage, bed surface, etc)

    Then i would have few additional questions:
    Can you do probe repeatability test?
    Do you have enabled ABL? Did specified compensation (settings or gcode)?
    Is extruder carriage (x axis) perpendicular to bed (y axis)?
