keep speed constant

[fermars 0]

Hi!

 

I have been using Cura for years. I started with the 15.04.6 which is an easy, fast and reliable version even today. I have installed long ago new versions 4.x and today I am using the latest 4.8.0. I still keep the version 15 installed on my PC because it keeps the speed constant on every layer and shell line it prints, so when I need faster printing, I usually generate the gcode with version 15 instead.

I would like to know if I can get the same behavior with 4.8.0 version, because even do I select the speed parameters all the same (see picture), Cura still slow down the speed on inner and/or outer walls:

 

 

Is there any setting that could be changed to avoid that? I have been checking all Speed parameters but cannot find any that helps.

 

The difference in time between Cura 4 and 15 in big parts could be several hours!

 

Thanks for your help.

Regards.

Strange - they should be consistent.  By the way - a travel speed of 60 is crazy slow.  Try 300 maybe?  Your printer should limit that speed automatically to what it is capable of.

 

I'm thinking maybe your inner walls are printing faster because they are thinner - to equalize the filament flow.  So you could uncheck "equalize filament flow" but then the quality might go down.  Instead I recommend you make all the walls the same thickness: Set the wall thickness to an integral value of the line width.  So if line width is 0.4mm make wall thickness 0.4 or 0.8 or 1.2 or 1.6, etc.  not 1mm or 1.5mm.

 

Basically make all the line widths the same including infill.  Make sure all the flows are at 100% as well.
