I faced the problem of printing bridges in Cura 3.1 (in Cura 3.2 I haven't checked yet).
I tried to print two test models, one test bridges at different temperatures, the second - calibration cube with holes (one hole is at the bottom and requires bridges).
Printed from Cura and slic3r PE, with close settings. In Slic3r there is a setting - "bridge printing Speed", however in Cura I could not find such a setting.
The print result of the temperature test: 2-Cura.jpg and 2-Slic3r.jpg.
The result of printing the calibration cube (bottom view): 3-Cura.jpg and 3-Slic3r.jpg.
Because of the poor quality print of the bridges there are 2 other problems:
printing of a continuous layer over filling occurs with breaks "threads" the surface contains a lot of torn holes;
printing with a step change in the density of fillings fails, because the "thread" of the next stage simply fall between the frame of the previous filling
The result of printing a step change in fill density: 4-Cura.jpg
Please help me how to configure Cura. I really like tactics that uses Cura when printing.
P.S.
I apologize for my English, is Google Translate
