I've notived that the PVA becomes noticably more ductile as it warms up.
With that in mind, the last couple of prints I've put the spool on the print bed at 30C for an hour or so. Both prints has succeed, but a sample size of two is not exactly data... I've looked through the material station doco, it makes not mention of temperature control. So I assume it doesn't.
Taking the spool out also gave me a chance to check the filament tip and sharpen it up. Sometimes it comes out of the extruder after depriming quite blunt, which has caused me issues in the past.
