Hi,
I've read through the entire print troubleshooting guide and shifting the recommended settings don't appear to fix my issue. My first layer is extremely spread out, except for the skirt. I did change to a BuildTak printing surface recently, but the skirt printing fine leads me to believe it's not a hardware issue.
Here's the first layer. You can see there's a lot of space between the lines, but the skirt appears to be normal.
Here's a completed print (I realize now this is a slightly different print, but I don't have a picture of the first layer of this one)
And here's the top layer. Maybe a touch of underextrusion, but not nearly enough to cause the first layer.
