Ulitmaker 3 Extended - PVA not loading

[Shirly 1]

Hi Everyone,

 

I had a similar query about a week or two ago and received some great tips which I tried but the problem still remains.

 

My issue is that when trying to feed the PVA, it will feed all the way down the tube but then stops before it reaches the print core and starts grinding, not able to move any further. The spool spool is loose and I have been there each time to check if it is getting stuck on anything.

 

The issue started with the PVA getting jammed in the feeder completely and me having to take the feeder apart to get it out. I was given the advice that the PVA might have had too much moisture so I dried it and it wouldnt feed through after this so then I tried a new roll of PVA and I am getting the same issue.

 

Any advice would be appreciated!

 

I have tried to clean the nozzle and make sure that it is not blocked and have ordered a new print core in case this is the issue but the PVA doesnt seem to be even getting that far for this to be the problem. I feel like it is getting jammed in the feeder itself.

 

Thank you!
