Bumpy Infill PETG

Filament

Hello,
I am having bumps sticking up on the top of infill layers of my PETG print. I am printing on Lulzbot Taz6 with PolyLite PETG.

I use default PolyLitePETG settings with the following changes:

Print Tempt Initial Layer: 232
Build Plate Temp: 66
Build Plate Initial Temp: 72
Flow: 98%
Retract Dist: 1.2 mm
Retract Speed: 12 mm/s
Print Speed: 70
Travel Speed: 180
Fan Speed: 75%

How do I get rid of these infill bumps?

Thanks!

Looks like you infill isn’t dense enough and it’s trying to do a top layer, just increase the density and amount of top layers.
