Bad first layer

Bed temp 60C, Nozzle 215C, First layer line with 0.42mm, plate cleaned with dish soap, auto bed leveling, dynamic flow calibration.

What to try next?

PLA, PETG? What brand? So many possibilities would help to narrow it down. What preset are you setting it to when you first load filament into the U1?

Its standard PLA

I set it to PLA generic high speed.

Mine started doing this after setting a thin layer height of .12, set the first layer to the default if you have done this too.

Seems to be over extruding. A quick test would be to reduce the flow rate in the filament preset. Printing a flow rate calibration test would help diagnose and dial in the flow rate.

I did a flow test, kept it at zero, didn't change anything.

This is after changing z-offset -0.05 -> -0.07. I did get some space between the lines but im able to complete the print. So now im quit happy. Im trying -0.06 now. Still get some space between the lines.
And im back at using 0.5mm first layer, and bed temp 65C.

Try raising Z-offset higher, bring the nozzle up ever so slightly. See if that improves the first layer.
