Hi, Does anyone recognise this ringing pattern? I'm having some difficulty obtaining a smooth surface around the hull of benchy. I have checked the tension of the belts, adjusted the carriages, and tightened the frame. I have also tried reducing the jerk and placing the printer on the ground. The final image is an issue I am having with my X axis. I am unable to get the belt to track correctly, and this is rubbing on the underside of the aluminum. Is this the cause of the ringing? Thanks in advance for any support.
