UM 2+ Flow Rate

[Idahobie 0]

I have a UM2+ (upgraded from a UM2) that prints beautifully, but with the .80 nozzle, I have to set the flow multiplier in Simplify3D to 140% to get past underextruding bottom and top layers.  I'm using 20mm/second speed and 0.40 layer height.

 

I have never been able to get a print sliced in Cura because I can't adjust the overall flow rate up that high.

 

Is this normal, or is it compensating for a problem somewhere?

If you want full control over material settings in Cura (including setting the flow rate), change the gcode flavor from "Ultimaker 2" to "Marlin". You can then set the flow rate to anything you like.

Thanks for the tip!  I will try that.

I'd still like to know if a flow rate adjustment of 140% is within the range of normal, or if I have something else going one.
