How to improve this Benchy? BIQU B1 I have just acquired my first 3D printer, a BIQU B1. Overall I'm quite pleased with the printing results but I'm having minor defects on the Benchy test. I'm not sure what the problem is, but I guess it's related to the overhang and maybe vibrations.
My print settings are:

Software: Ultimaker Cura
Temp: 205 °C
Heatbed temp: 60 °C
Height: 0.2 mm
Print speed: 60 mm/s
Travel speed: 150 mm/s
Flow: 94 %
From the Benchys, it is apparent that the temperature is quite high or that there is not enough part cooling flow. This can be seen from the sagging of unsupported overhanging structures. Considering the bow of the Benchy is quite fine, the most probable cause is the temperature, usually with too less part cooling flow, the bow shows defects.
Please note that a Benchy is a gimmick that does show defects, but it isn't a calibration object, there are many other different test prints available.
