I have been trying to solve this myself for a while, but I am stumped. I have an Anet A8. When I first got it and used the version of CURA that came with it(15 something I think), it printed OK. After upgrading to the newer version of CURA (3.4), the prints are all flimsy. I have tried tweaking infill and a bunch of other settings. Also tried using an ANET A8 profile from thingiverse.
Lateley switched to just printing test cubes. Same results, but I don't have pictures of them. You can see in the photo how flimsy/thin the print is. You can basically just crush them in your hands.
I appreciate any advice suggestions.
