I've gone through the print troubleshooting guide but can't seem to figure this one out. Whenever I print ABS, concentric or rect fill, 0.1 through 0.3, the first layer has a consistent ripple pattern with areas that are perfect and areas that are rippled. This is both in large and small parts, it doesn't seem related to length. It's on a freshly cleaned heated glass that was just coated for ABS -- almost perfectly flat.
This image is a 0.25 first layer. The scar on it suggests over-extrusion or under-retraction. I've tried reducing the the extrusion multiplier (down to 90%) and it doesn't seem to change anything at all, it always looks like this:
