¶ Lines not connected to walls
In the example below, the printed lines don't connect with each other.
¶ Potential causes and solutions
¶ 1. K-factor set too high
The most common problem which causes such print quality issues, where the printed lines are not touching with each other is caused by a K-factor which is incorrectly set to a very high value.
For Bambu Lab printers, the K-factor is calibrated using the Flow Dynamics Calibration available in Bambu Studio.
A very common mistake is to perform the calibration, and instead of inserting the correct value (ex: 0.025) the user inserts 0.25 which is ten times higher than expected.
Most common results for regular filaments give a K-factor value between 0.02 and 0.04 as long as the hotend is free from any partial clog, and the extruder is clean.
IMPORTANT: It is rare for the filament to require a K-factor larger than 0.05 and very rare to use a K factor larger than 0.1
If you have performed a Flow Dynamics Calibration, and the K-factor is larger than 0.04-0.05, we strongly recommend cleaning the extruder and the hotend before performing the Flow Dynamics Calibration again.
