		<description><![CDATA[I keep shattering glass printbed surfaces on my MendelMax printer. I suspect that it&#8217;s caused by the combination of using plain glass from old flatbed scanners, and that the glass is 1-inch bigger than the heater on all 4 sides. I made this custom sized heater by taping down nichrome wire, to the back of [...]]]></description>

		<description><![CDATA[I spent some time printing several test parts, trying to determine the source of some of the ripples that may appear after a sharp corner in a print. Firmware settings were tweaked to aggravate the problem, raising the &#8220;jerk&#8221; value high enough to disable acceleration. This print was done from manually generated gcode. The part [...]]]></description>

		<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>

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>
