<DIV>Yes, I've found this to be normal for completely new components. There are
often greases, oils and other volatiles used in the manufacturing and assembly
process that take time to work thru and burn out of the extrusion path.</DIV>
<DIV> </DIV>
<DIV>For nozzles, keep an eye open for clogs. Sometimes it's non-thermal plastic
"fuzz" that bungs things up. Other times it's little pieces of metal left over
from machining them.</DIV>

<DIV>A friend of mine just installed some new hot ends on his 3D Touch
printers.</DIV>
<DIV> </DIV>
<DIV>After installation, and when he turned it on, he noticed a foul stench
arising from the hot ends. He said they really stink.</DIV>
<DIV> </DIV>
<DIV>He mentioned that there is some potting compound on the hot ends and
thinks that they may not have gone through a bake-out procedure.</DIV>
<DIV> </DIV>
<DIV>Does anyone know if it is “not unusual” for a hot end to stink, and if
so, how long does it take for the smell to go away.</DIV>
<DIV> </DIV>
<DIV>Thanks for any assistance.</DIV>
