		<description><![CDATA[I recently switched to the Kliment fork of the TonokIP fork of the Hydra-MMM firmware. 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>

Most of the parts were printed one at a time, I didn&#8217;t use the production parts files. The parts are now in the hands of [...]]]></description>

		<description><![CDATA[I made some links of chain, arranged just so that I could slip a previously printed link over two adjacent links, while they were still being printed. 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>

The new one seems better, but I still have a little bit of wobble from a still undetermined source. Here are a few recent prints. I recently started using the &#8220;Dimension&#8221; [...]]]></description>

		<description><![CDATA[I thought the firmware I&#8217;ve been using had PID temperature control, but it turns out it was using a simple on/off thermostat routine that caused the extruder temperature to have big variations. Here are some prints of a RepRap Mendel part, basically a small cylinder. Due to the small size of the part quality really [...]]]></description>
