Print speed CURA 3.1 or 3.2

Recommended Posts

When the object is sliced and the gcode created, what is the speed setting in the gcode? Is the speed something I can modify in the gcode?

 

I ask because no matter the speed I select in CURA, the prints are always printed at the same speed. To reduce the speed I have manually reduce the print speed on my machine.

Ah that was a bug, I forget the version but it did get sorted. Maybe it has been reintroduced; the speed setting should be the speed/speeds you have set in Cura. Yes it can be modified in the g-code, just load it into an editor with a search function.Ii is dead easy to change if, ignoring the first layer, you set all your printspeeds (not travel speed) to the same value. In the editor search for      Layer:1     . You will probably see an M140, M106 and G0 commands. Then probably a comment  ;type:wall-inner    , or similar. The next line will be a G1 command starting with an F parameter; divide the figure by 60 and that is the speed, nn/ms, that Cura has set the printer. So multiply your required print speed by 60 and type in that number.

 

It more time consuming if you do not have all the print speeds the same because then you will get several G1 commands with F parameter on every layer. I guess you could use search replace to fix them all.

Also beware if you have entered a number against slow layers because each of the first few layers will have a G0 F command (I assume) and you will need to fix them.

If you used the 3.1 beta, your configuration is in a conflicted state, which may prevent you from making changes to settings such as printing speed.

 

Go to Help -> Show configuration folder, and then quit Cura. In the configuration folder, go to the parent folder and remove both the 3.1 and 3.2 folder. When you start Cura again, it will reimport your configuration from a previous version (eg 3.0).

      The goal of this contest is to design a set of people figurines that could be used in such a project to make an area, office or mall seem populated. 
      Think of different types of people in different environments, like walking people, people standing still, working people, and both men and women.

    • Taking Advantage of DfAM
      This is a statement that’s often made about AM/3DP. I'll focus on the way DfAM can take advantage of some of the unique capabilities that AM and 3DP have to offer. I personally think that the use of AM/3DP for light-weighting is one of it’s most exciting possibilities and one that could play a key part in the sustainability of design and manufacturing in the future.
