		<description><![CDATA[I&#8217;ve finished building a MendelMax 3D printer. The controller is a RAMPS 1.4 from Ultimachine, and the hot-end is a MakerGear plastruder, with a 0.25mm nozzle, pushing 1.7mm filament. I used the MendelMax &#8220;1.0&#8243; parts, as the &#8220;1.5&#8243; hadn&#8217;t been released when I started printing. I strayed from the stock parts in a few places, [...]]]></description>

The tiny pauses between g-code segments are all but gone, and I&#8217;ve been re-printing some things to do before &#038; after comparisons. The black PLA-4043D Hyperboloid was printed with the Tonokip firmware, and the recent natural 4043D PLA was printed [...]]]></description>

		<description><![CDATA[I did a test print at 0.08mm layers, the smallest layer height I&#8217;ve attempted yet. I used a Makergear Plastruder, and black Ultimachine 4043D PLA. Skeinforge sliced it onto 187 layers. It was not a fast print, taking about 2.5 hours. Aside from a kind of smeary top layer, it came out ok. Pictures follow:]]></description>

Purists may take exception, but I think it&#8217;s kind of cool. The links were printed with a 0.4mm MakerGear nozzle, using 0.26mm layers. All the &#8216;extra shells&#8217; settings [...]]]></description>
