i use the Formfutura PVA and it seems to be easy to print at 185-200°C. Nice adhesion to the naked glas at 70-85°C and good printing quality as long as it's the only material and there are no retractions.
If I use it in dual extrusion though, i cant make it past the 2-3 layer of PLA/PETG (no bonding problems between the two) without clogging the 0.4mm nozzle (bontech extruder). I tried printing with fast/slow/no retractions but it seems as soon as the extrusion of PVA is stopped once, the process is more or less dead. Does anyone have an idea what other options there possibly are? Wipetower/wall do not help either...
