Hello fellow withprinters. Whats happening here? Stringing is not the problem, if i print string tests, they are good. Its only in holes, the walls wont stick. Any suggestions for a fix?
Edit: Found the problem. The temperature sensor was faulty. Changed it and now everything is fine.
This is somewhat normal for FDM 3D printing. It’s a known behavior of filament in its molten state on the interior walls. As the nozzle goes around, it’s always at a tangent to previously laid filament, and can have the effect of pulling just-laid filament off of its bedding into the previous layer.
It’s one of those things that to fully understand I’d have to find one of the dissertations one of the community members did.
But with marlin firmware (using klipper right now) it worked…
Edit: Black is Marlin, white is klipper.
Different filaments will print differently, so it might not be the firmware
Doesn’t look like the same gcode though. Initial layer lines are facing opposite directions. You also have small brown inclusions in the white one, which is usually the result of burning/dripping filament from a leak.
