Can you share some details about your printer, nozzle size, filament, print settings etc?

 

It would also help to see this print in the position it was oriented on the plate.  The gaps appear to be at their maximum nearly 180 deg apart.

 

For example, if this was an UMO, I'd check the xy stepper belt tension first, then move up to the larger belts, and go from there.

    have checked every bolt
    a more closer look shows a mistake in the print direction at 4 places
    see image
    now i think that the y axis stepper motor skips steps at direction change
    have ordered a new one
    fingers crossed?
