Any idea why this is happening?

Brand new Ultimaker 3 Extended.

XY calibrated successfully

Manual bed leveling multiple times

About 4 prints in, yet to be impressed - and HAVE to believe it's me.

To break it down to simple parts...I chose to print a model that was single print and no supports.

Scaled it to 400%.

With a single extruder and the included Ultimaker Silver PLA filament, I am seeing stringing from point-to-point and a strange wave effect on the first layer.

Thoughts? Concerns?

This is pretty normal. The wave effect means you are too close but you want to be "too close" because if you don't squish the first layer well then the part won't stick.

that stringing is so thin you can whisp away thousands of those to nothing in 1 second with a heat gun. If you still get lots of stringin on higher layers possibly lower the nozzle temp by 5C to 10C but that stringing looks pretty minor. You should see more typical stringing, lol, which can be a pain to clean up.

Several settings are different in the first layer, to optimise for bed adhesion. You will see that the top layer of your objects will look perfect, and will not have these waves.
