First / solid layers are dimensional smaller than infill layers

[rhoogenboom 3]

Hi, 

 

I'm looking for some pointers as what to check/adjust to get this issue resolved on my prints.

 

These prints are done in PLA, but aren't material specific. Cura versions: this happens with 3.5.0 and the previous 3.4.1. I don't think it's Cura version specific, I've had this issue for a while.

 

This is printed at the default 'fine' setting of 0.1mm and a modified fine setting where initial layer height was decreased and print speed reduced to 35mm/s 

 

When I print, the bottom/100% infill layers seem to be dimensionally smaller than the layers higher up which are printed with infill. I even aborted a print, as you can see in the pictures where it shows the dimensional wideness changes at the infill printed layers.

 

Any thoughts or ideas of things I could change to fix this issue?

 

Picture 1 through 4 some examples where the first layers are smaller than the subsequent ones. 

 

Picture 5 through 7 you can see it starts when printing infills. 

 

Upload of pictures will be after posting as I need to do that from my phone.

 

Cheers,

 

Richard

I’m trying now to increase the bottom top layer width to 0.45 from 0.35. Lets see if that makes a difference.
