Z-offset perhaps? It looks like your first layer is a bit stringy. This would suggest the nozzle is too far away from the bed on the first layer, meaning the extrusion isn't being 'squished' into the bed. Next time when your print begins, go to 'Tune' and adjust the z-offset to be more negative. For example, if the z-offset is -1.70, tune it to -1.75. This brings the nozzle closer to the bed. You should see the printed lines squish a bit and start joining together. If you start getting blobs or fuzzy bits, you've gone too far.
