I have be testing printing with ABS using PVA as the support material. However I am having issues where the ABS doesn’t want to stick to the PVA. I have the bed at 80°C, ABS nozzle at 235°C, and the PVA nozzle at 190°C. I set the interface layer to be solid in the hope that I would get a very nice overhang.
Any ideas? Also I have been fighting the oozing of the PVA. I added a retract which helped, but still would like to improve a little.
