Infill lacking on first layer _only_

Anyone seen this issue before? It looks like the infill amount is not correct on the first layer only, like so:

Settings all look good in slic3r, in fact, I tried turning up the first layer extrusion width setting, but no luck.

I also consulted the pictorial diagnosis guide.

Any other ideas?

Thanks!

My guess is that your hotend is slightly to high. You might try measuring the height of the first layer and comparing it to the slicer height.

Unfortunately, that wasn't the issue.

It looks like _just_ the brim doesn't extrude properly.

Any ideas? Thanks!

I tried upgrading slic3r to 1.2.6.

I also tried turning the first layer extrusion width all the way up to 400%.

Still no luck. The brim does not stick to itself, it just looks like a spiral.

What is going on here?

Thanks!

You can also manually change the nozzle width in the slicer to see if that helps.

Just an FYI setting the nozzle width and changing the extrusion multiplier do the same basic thing. Extrusion multiplier set to 1 means 100% of what the nozzle is set to while lower numbers such at .85 means extrude less and higher numbers such as 1.15 means extrude more material. But these will affect the entire model and not just the first layer.
