Recommended Infill Speed / Temp ?

[AJDouglas 0]

Hello,

I am currently using the Cura default speed and temp for Ultimaker PLA at .15 layer height (70mm/s at 200C) and am getting incredible underextrusion on the infill. The outer layers all look as hoped. Can anyone offer any advice in regard to a better ratio? I am just surprised the default produced such a poor result.[media-thumb=30238]

Speed and temp are related. The faster you print the more heat you need. I'm sure @gr5 will copy paste a very old temp/speed table from um2 (not plus) ratios. Something like this https://ultimaker.com/en/community/16573-printing-speed#reply-111348

Are you using cura 2.X or 15.x? The newer versions of cura have the infill at a higher speed. I completely disagree with this philosophy. I'm guessing your infill is much faster than 70mm/sec.

Anyway, what type of printer do you have? Please update your profile settings. 70mm/sec at 200C at .15mm layers is much too fast for a um2. I'm guessing this is a um3?
