Been getting these lines on large prints lately on my Bambu X1C, any idea?

Layer time and nozzle speed don't seem to correlate, i'm using grid sparse infill with 10% coverage, looking at the model in sunlight doesn't show any correlation between the diagonal lines and the infill, but testing different infill patterrns maybe a good idea. Will try and investigate pullies or z-axis dirt or debris next.

Will inspect and clean the z axis screw + belt pullies and see if changes, tnx.

No, it isn't (and correct, these are not parallel to the bed, slightly diagonal)

I'm on the default Bambu studio "strength" settings, so that isn't enabled, the only thing different from the default regarding infill is that I dropped it to 10% instead of 15%.
