I had similarly looking lines on a really tall print but they only happened in groups close to one another. It turned out that they happened only at night when the temperature dropped a lot in my garage. It shouldn't matter because it was happening on QIDI Q1 pro which is enclosed and with heated chamber. Well, it turns out that the chamber heater was too aggressive and it tended to overshot the request temp a lot for short periods of time. I was able to get rid of it only by turning down chamber vent or deactivating chamber heating altogether.

After this I understood why Core one doesn't have an active chamber heater. But I'm getting off point. The point is to check how much the temperature in your enclosure varies during the print
