lifting?

I'm terribly confused. I've not come across the problem before. It almost looks like it's increasing Z as it prints? Primer blob and outer layer of brim squish pretty good, but gets worse as it prints. That's all supposed to be the same layer.

Long video, but you can def see where it changes. I check the tool head output on the web UI, says it's still at 1st layer height, .48 (running .6 nozzle)

You have a cable crossing underneath your gantry 😬 Sounds like thermal warping of the gantry

I've noticed brim has a different line spacing. It should not used to tune your Z offset. Lift up a bit until brim lines are just clearly visible. Then tune your Z offset on a proper first layer.
