            <description><![CDATA[ Hm dont know. Sometimes he makes this ripples, sometimes not. When not the prints are very good (Perimeters, closed top surface, ...). Maybe the printer has sometimes trouble to feed?<br />

The PTFE tube in the HotEnd got degraded and i had to replace it by a PTFE hose i made on a lathe. But these turned PTFE hoses go bust much faster then theses tubes.]]></description>
