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 isn’t stringing though. It’s the outter perimeter that is getting partially pulled away from the print. If you look at the second picture on the bottom hole, there is more visible looping of the filament. Circle perimeters generally print in circles with consistent start and end points without the need to cross across a void like that.
Printing inner perimeters first may help here without having to do extrusion tweaking. If that isn’t the problem, slowing down perimeters (or the entire print) will give the layer more time to bond.
However, there could be a mechanical issue starting to show as well. If there is slop in one direction and not the other, a belt gear on the stepper could be getting loose. It’s something to check, anyway.
But if you enable “Avoid crossing perimeters” this problem will still not occur.
Since OP mentioned a switch from Marlin to Klipper, it could also be acceleration settings or something like it.
