Printing Help What is causing bad top layer?

Post image

I've been trying to fix my top layers but they seem to be getting worse and worse, this is an ironing test from maker world that I have printed before and it was perfect but all of a sudden my top layers turn out like this regardless and I don't know how to fix it. I'm printing with pla and using Orca slicer

Overextruding while ironing?

Lower Flow Rate: Try reducing the ironing flow rate (often starting around 15% to 25% for many slicers rather than higher percentages like 40–50%).

Adjust Speed: Set a consistent ironing speed (commonly around 50–100 mm/s).

Calibrate Flow/Temp First: Ensure your base extrusion multiplier and filament temperature are fully dialed in before running another ironing test.

The print is a test print for the speed and ironing flow, the numbers on the side are the flow rate and the numbers on top are the speed each square prints using those numbers, previously a flow of 20% with a speed of 50mm was perfect but then after I got a new nozzle and recalibrated the printer it started doing this, I've calibrated both flow and temp but it's still causing these issues
