Recently upgraded to the v2 dual extruder and have been able to print ABS / ABS without problem.
However, what I’d really like to be printing is PLA with PVA support structures. The “profile” that is pre-loaded on Cura 18.03 for the dual extruder doesn’t seem to be working the way I’d like.
I’ve slowed down the print speed to 10 mm/s, and checked/purged the extruders, to make sure they’re not clogged, but the PVA is still having an exceedingly difficult time extruding, and grinds/buckles against the drive gear.
Anyone have any tips on this, or would like to share the Cura Profile they use when printing PLA / PVA?
