WEhat material are you using? This looks like an underextrusion issue and many things can cause that, such as feeder grinding, too low of a temp, etc.

I used PVA for supporter.. 

[PVA going thinner during printing (big size model)]

Hello I'm Ultimaker 3 Extended user.

I want to ask some questions about problem during the printing.

Like this picture, I try to print big earthen pot(pottery) model, it takes full size of build plate.

It would have been takes 5 days if it had succeeded. 

 

1. I put glue on bed, so it can be a problem about lost G-code in later (steadily)?? 

2. It was unreasonable size for printing?(fit in build plate narrowly, I tried small size the same model and it was succeeded. )

3. The long time printing does not easy to succeed?

[filaments become thin among printing,,,]

I used ultimaker 3 extended 1year, until now I have many problem.

The biggest problem is in middle of printing PVA of PLA become thin and head is clogged and at feeder, filament are crumbled.

So I cleaned up the feeder and header after that I confirmed the filaments are going out side well. But I failed printing in eight cases out of ten until now..

How can I do with like this problem???
