How to avoid extruder clogging when printing with PVA

[david-hunter]

Hi there,

I'm having issues with printing PVA whereby it'll get clogged in the extruder (I have a dual-extruder Flashforge Creator Pro; the extruder is remaining heated when not actively printing and so the PVA clogs up the extruder).

I note on this Simplify3D PVA webpage it says: "In multi-extruder setups, cooling down the PVA hotend during idle times can prevent oozing and clogging", but I can't seem to find any setting that'd do this in Simplify3D.

Any ideas how to achieve this please?

Thanks in advance,
Dave

It turned out it was bad filament. Replaced it and all worked fine.
