Monoprice i3 Mini (Wanhao i3 Mini clone) sudden persistent under-extrusion (maybe)?

Thanks for the reply, Jamcultur!

I originally heard clicking from the filament feeder gear in the very beginning. It turned out to be related to a (very) dirty feed cog. I cleaned it, printed an upgrade for the filament feeder clamp, and had no clicking or feeding issue since.

Just to be sure it isn't the issue, I'll take it apart and examine/clean that mechanism again. I'll also change the layer height to 0.2mm, and again to 0.1 if the overall issue is unchanged.

If anything changes, I'll take more pictures and post them like last time.

Edit: I accidentally reversed the two layer height values in my original post. I'll edit that post to correct it, too.
