I’ve got some great prints on this RepRap now that I’ve figured out the “infill every N layers” and the “solid layers” connection in slic3r.

Nice job.

Describe what you mean? I have not played with those settings yet…

You can skip infill when doing low layer height prints. But a thin solid layer is hard, so I entered 10 for solid layer. Then at least two of them are full thickness. I’ll try and illustrate it.
