as far as heating p goes. The flashforge bed heats up quicker but the delta hotend is much faster to heat than the flashforge's.

Currently printing another duct, with angled end and designed for clip in nozzles.

Now to design some parametric nozzles. :-)
Far as nozzles go - happy with the 0.5.
Haven't noticed any major quality differences, and I'm sure it helps with the flexible filaments.
And at the end of the day the delta is mainly for printing bigger stuff faster.

So how have you got your fan setup now then ?
