Bridges are created with very high speed

Recommended Posts

Posted · Bridges are created with very high speed

Hi there, I'm pretty new to 3D printing and only got my printer a few days ago, so quite a lot of this is pretty new to me.


I wanted to print a toy bed for my child, which contains quite some bridges, so I started to have a look at some bridging test from thingiverse.

From what I have read on the net, bridges should get created with slower movement than other parts and with less extrusion, so the filament gets more time to cool.


When I slice the above mentioned part in Cura, the bridge speed is very high though (much higher than any of the walls).

I already thought I might have changed some settings that cause this, but this happens to me even after deleting my Cura configuration directory and starting with a fresh configuration.

Also - even after checking/changing the experimental bridge settings, those settings don't seem to have any effect.

Due to the fast speed in combination with the reduced flow rate the bridges in the sample mentioned above are working, but are very thin. (only printed until the first 3 bridges had finished)

Your help would be very much appreciated!

    I don't know if slower or faster bridging is better.  If more extrusion or less than normal.  Or maybe more extrusion initially then less as it goes across.  I don't know.  But there are better and more bridging options in this version of cura.  Also there are features to consider that the first layer over infill is also "bridging" (this feature off by default).


    This version is by our own @burtoogle.  I use it almost exclusively:

    is it possible that this is somehow related to my problem with much too high brim speed?

    Are your bridges perhaps printed with the maximum speed the printer's firmware allows? Because that is happening with my brim. Could you please take a look at the Slicer Preview and see if the nozzle in the preview also ignores your bridge speed and just jumps from one end to the other with infinite speed?
