  • Going by just the failed circular print, you definitely don’t have a good Z offset. There’s no smoosh there. Putting it lower will smoosh the filament into the print bed (Part of why the PEI sheet is textured. The filament smooshed in the texture helps hold it better than a flat print bed). The fact that you can see through your first layer is bad.

    The top layers of your other failed prints look good, so I say we can rule out under/over-extrusion.


  • The humidity issue IMO is often overblown. It’s really environment specific. In my old place my relative humidity was 35% so wet filament was never a problem. It’d be good to get a hygrometer to see where you’re at before you start buying fancy filament dryers or accidentally melting your spools in the oven. If your area is generally high humidity then it can help. With PLA though it’s not going to make a huge difference.




  • Hard to know what’s going on without pictures. Could be any number of things. My first thought is over-extrusion if the nozzle is catching your print and knocking it over. Or maybe you need Z hop between layers. I’ve only used Prusaslicer so can’t say what to do to help in Cura. If you’ve completely replaced the hot end, you should be re-tuning your printer (PID tuning for correct temps, e-steps for correct extrusion amounts, etc). If it’s adhesion problems where the print isn’t sticking to the bed, applying some glue stick can help keep things secure.
