Consistent print error


I’m having a strange problem, it’s a consistent print error at the same point in the print all the time (example above).
I have tried changing many settings speed, flow, temp, location on bed, etc with varying degrees of success but there is always an error at the same point on the print that looks similar each time.

I created the small test print to see if I could solve the problem but with no luck.

Tried a different filament, similar results but not as noticeable.

Any ideas welcome.
