Cura not extruding enough material in GCode

Recommended Posts

Posted · Cura not extruding enough material in GCode

Hey Guys,

 

I have been having under extrusion issues and pinned down the issue to something I found in the GCode that cura compiles. The two GCodes below represent two different models loaded into cura, but with all of the same material and printer settings, the only difference is the file that was opened in cura. If you look at the first bit when it prints the prime tower, it has all the same x and y values, but the extrusion amounts for the second file (the one I need to print..) are almost a magnitude smaller than the one that prints normally. Any ideas as to what causes this or how to fix? The file I am trying to print did come from Netfabb if that has any effect.

First File (prints normally)

Posted · Cura not extruding enough material in GCode

Hello @distance28, I can't tell looking at those fragments what the problem is. So, is it possible for you to save the project file (File -> Save) and attach the resulting .3mf file to this thread? Thanks.
