[solved] "Porous", weak print under Linux

Recommended Posts

Posted · [solved] "Porous", weak print under Linux

Quick post to describe a problem I had and the solution I found, hoping it can help somebody else.

 

Following a reinstall of my Linux (from Mint to Manjaro) and the launching of Cura, I encountered some issues with the backup of my profiles (at this point I probably messed up with the files). However, after deleting all config/personnal files from the /home and reimporting clean .curaprofile files, my prints were inconsistent, weak, porous, almost flexible and transparent, and sometimes broke when I tried to unstick them from the heated bedleft bad print, right correct print from another computer with same model, same material, same settings.

After opening the gcode of each of these prints, it appeared that the bad one had severe underextrusion, and all the values (filament used and "E" value after G1 codes) were lower by a factor 0.377039. This value appears to be (1.75mm / 2.85mm)²: somehow, Cura considered that my filament was 2.85mm instead of the 1.75mm specified in the extruder settings. The filament diameter wasn't mentioned anywhere else (material or profile). To solve this, I erased the old 1.75mm in the extruder settings (which didn't seemed to be taken into account) and rewrite it.
