			<content type="html"><![CDATA[<p>It is ABS (Sabic MG94), which is listed on the kit&#039;s product page. 210C is already too hot, you should be extruding at 180-190C. The reason you&#039;re thinking 220-230 is that most 3D printer hotends measure the heater temperature, not the nozzle temperature.</p><p>Do you have the wooden thrust plate? If so, is the thrust bearing getting pressed into the wood? This will cause binding, as the thrust gets transferred to the motor and pushes it out of axial alignment. The fix is a new harder material thrust plate. If that&#039;s the issue, shoot me an email (filastruder@gmail) and we&#039;ll get a new thrust plate on the way free of charge.</p>]]></content>

			<content type="html"><![CDATA[<p>Getting persistent nipple twist as well, even at 210C... auger extrudes normally for a few seconds then couples to nozzle/barrel. waiting for cool-down and correcting problem is getting to be a royal PIA. <br />Perhaps it would have helped if the clean-out plastic supplied in the kit had an identifying label.&nbsp; Is it ABS? If so, wouldn&#039;t a more appropriate temperature be 220-230?</p>]]></content>

			<content type="html"><![CDATA[<p>Yeah, and so while I did the initial run out and have a perfect coil of gray fading to white coil for it, I am not sure this thing is for me. I would rather buy retail filament.&nbsp; This thing is just too fiddly for me. Too much ramen and fumes for me, and the OSP master batch colors are not working out like I want. So maybe look for it on eBay along with 8 pounds of pellets and master batch, or PM.</p>]]></content>

			<content type="html"><![CDATA[<p>Mine did this and crushed the dowel when the motor got in a bind, I took off the nozzle, while it was still hot and there was a chunk of metal in the blob of plastic right behind the nozzle. I filed everything down real good before starting, but I guess I missed some when cleaning it before use. (5hr into the 8 hr clean out).</p>]]></content>

			<content type="html"><![CDATA[<p>I ran into this issue, and I believe it was caused by the plastic not being sufficiently liquid in the barrel, causing the feed screw (auger) to transfer torque through the thick plastic to the barrel; I don&#039;t think it has anything to do with the nozzle. Now, based on Tim&#039;s instructions, I let it get up to temperature (180), then wait another 15 minutes to let the heat saturate the plastic further down the barrel (i.e. further from the heating element and the thermister), and then it starts smoothly. Since then, no troubles.</p><p>Before, I was starting the motor as soon as the thermistor reached the target temperature, and I repeatedly had to rotate the barrel repeatedly to keep the feed hole at the top. And that&#039;s pretty irritating - you have to unscrew four bolts and hold the whole assembly together, rotate it 90 or 180 degrees, then bolt it back in place. And I think that&#039;s why I was having &quot;washer&quot; problems. After rotating the barrel and/or replacing the washers a few times, I am very happy waiting 15 minutes. Plenty of time to make a good cup of coffee, then come back and flip the motor on.</p>]]></content>
