Bottom layer issues on PVA support

[JDE23 0]

Hi all,

 

I'm having issues with the bottom layer peeling when printing on a PVA support structure - see photos attached. Can anyone suggest what is causing this issue, and how I might solve it?

 

Thanks!

Josh

My suggestion: don't use PVA, use breakaway.

If you look at the layer-view in Cura, I suppose it shows support in those areas?

 

If so, it looks like there was no support at all in the areas where the spaghetti occured? Maybe the PVA-nozzle clogged and stopped extruding PVA, or there was huge underextrusion? (Too wet PVA?)

 

But I don't have a printer with dual extrusion, so I can't give much suggestions for handling.
