Why did you stop the print?  The pva looks fine.  I'm not sure what I'm looking for.  PVA doesn't print as beautifully as PLA but it should still be valuable support.

 

Anyway if the PVA isn't working properly it's usually because you need to dry it.  Set the print bed to 80C and put the PVA on the bed with a towel over it overnight.

 

If your PVA is very wet you can hear it sizzling and popping while printing and sometimes see steam coming out and the PVA is snowy.  But sometimes the PVA is only a little wet and it doesn't print well but you still don't hear any popping.  Never leave PVA on the printer when not in use.  I just lift the lever on the feeder and slide it out and then slide it back in for the next print.  I keep my PVA in a 2 gallon (3 liter) resealable bag with lots of dessicant (around 300 grams dessicant which I have to bake every 2 months).

    • "Back To The Future" using Generative Design & Investment Casting
      Designing for light-weight parts is becoming more important, and I’m a firm believer in the need to produce lighter weight, less over-engineered parts for the future. This is for sustainability reasons because we need to be using less raw materials and, in things like transportation, it impacts the energy usage of the product during it’s service life.
