Help, ripples in print

I don’t know if it’s my belts, problem with the printer, or what, but really need some help figuring this out.

I can’t get rid of these ripples occuring on the one side of the bed no matter what I do and it appears in any print.

I’ve done all calibrations for flow rate and flow dynamics.
Retightened the belts using the screws on the back
Max Volumetric Speed lowered to


@ 8mm
Nozzle @ 220C
Bed @ 60C
Hatchbox PLA
