I was looking for something to make PVA useable in the second nozzle, because it generally is not seable for supoort at all with this software. the pva is burned and clogged by the time it becomes time to extrude some... unless oyu have lots of pva support, and a very small cross section of model...
Lowering and upping the temperature will tke too long, it will still burn and clog.
What is needed is a system to extrude some PVA onto some sort of prime post to get rid of the degrading pva.
I tried a prime post, but it is still too infrequent.
This needs to happen not once per layer, but once per use settable unit of time. Even of the layer has some pva in it, there could be so much other material to print that it will burn on the time it takes to print the layer. So whatever happens I want to extrude some PVA every 3 minutes or something like that on a prime post.
