decrease the flow?

Recommended Posts

Hi folks,

I finaly upgraded my UM2 to UM2+. I also changed from cura 15.4 to cura 2.7

Now I´ve a problem with my first layer: It is ugly fat and awful high and rough.

By printing the secound layer, the nozzle srabs with an ugly noise over the harded and scattered surface of the first layer.

All settings a default, material PLA, temp 200, speed default. Distance between nozzle and buildplate is


Before upgrading, my first layers and the brim was like thin ricepaper, easy removable, all gaps of

supportstruktures on the bottom solveable.

How can I decrease the flow? Only increasing the speed of printing?

Thanks for answers.

if you're first layer height is at default 0.27 then I'd say the nozzle is too close to the build plate.

however check the line widths and see what values there are.

if they are wider than 0.4 then it might be worth a try setting then to 0.4mm

also check the diameter of the filament and ensure they are set correctly.

Hi bex,

thank you.

You are right: I didn´t recognised the hight of 0,27 of the first layer.

I´ll try another one with a decreased hight of the first layer, because I´ve no problems with adhesion.....

Although Bex solved your problem elegantly, there is a flow rate in the materials section of Cura 2.X and above. You may have to unhide the parameters to get to it. I have everything unhidden now for so long, I actually forget what is visible or not by default. But you may have to play with it for certain materials.
