New CTC printer came broken

They really should put teflon in the pipes, the constant nozzle blockages on mine are a real pain in the butt. The flashforge has teflon lined pipes, they are not expensive -- not sure why they would leave them out.

Sorry, I'm not going to be drawn into the 'Insert' debate again,
stated my opinion of those several times already .
(info gathered from online videos, since we have never used or needed guide-tubes with inserts)

We did convert to the all-thread type guide-tubes though,
they make different nozzle-thread lengths easy to adjust for
and set-screws hold them in place better:
