[Bridge problem in Cura 3.1]

Do you mean "bridge" speed?  What was the bridge speed in slic3r?

Not, the base speed is the speed at which all other speeds are calculated.

And correspond iner perimeter, nonsolid infil,

History with settings looks like this:
I downloaded the configuration file for Slic3r from the manufacturer of the filament "Filamentarno!".
Printed in Slic3r.
Then in Cura 3, took the recommended setting for the 0.2 mm layer and changed based on The slic3r settings.
But I could not find where to enter the speed of printing bridges.

"Filamentarno!"/Slic3r print speed of bridges = 20 mm/s

3) Is it only the bridge speed that makes the difference?  What happens if:

bridge speed = slicing speed

I don't know, I haven't experimented yet.

cura already has this feature, you can put multiple parts on the buildplate and it will print 1 entirely before moving onto the next one, and completing that one before moving onto the next. you just need to list the size of your hotend in the machine definition so it knows how large it is so it doesnt hit anything.

lance-greene, The idea is to not print the entire part at a time, and to print a few layers, then several layers of another part, then it repeats.
I also thought about this possibility. Then you can place the parts quite close to each other. And this will be less stringing.

[Bridge problem in Cura 3.1]

 

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:

1. printing of a continuous layer over filling occurs with breaks "threads" the surface contains a lot of torn holes;
2. 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.
