Blisters

[RWC 0]

I am having a terrible time with blisters and holes in my horizontal surfaces.  See first attachment.  I have been struggling with this for a week or so.  I have added top layers, increased temp, lowered temp, increased extruder % output.  Anything I could think of or find on line.  I have come to the conclusion it is the garbage I am getting for infill.  See second attachment.  I am a newbie so I am betting some of you more experienced folks have seen this before and can point me in the right direction

Thanks

The garbage in the infill is normal because the printer doesn't retract when printing the infill to save time and because it doesn't matter how the infill looks like.

 

Have you checked this article:

Adding more top layer can also help.

Really? Even accounting for the lack of retraction during infill it really shouldn't look as bad as that. Something is wrong there...

Are not the speeds for infill a bit high on average? Maybe try slowing them down a bit.

You are right, I haven't zoomed into the picture.

If you use the standard settings I think they are but lol if you use my settings they are not. Quite possibly faster speed causing under extrusion
