Hi!

I am developing a 3D printer software for a univeristy project and I need to calculate the E value in mm. I have one equation but it seems too much material is extruded and I think my equation is wrong.

My equation is:

Does anyone know if this is ok?

Thank you.

My equation is:

//Distance between points double difx=pow((x2-x1),2); double dify=pow((y2-y1),2); double dist=sqrt(difx+dify); double MaterialWidth = min( max(MinimumLineWidth,(ExtrudedMaterialWidthRatio*LayerThickness)),MaximumLineWidth); double pA = pow(MaterialWidth ,2); double pD = pow(FilamentDiameter,2); double f = ExtrusionFactor* ( pA / pD ); double res = f * dist; return res;

Does anyone know if this is ok?

Thank you.

"too much material is extruded" depends on your "ExtrusionFactor" which looks like it is supposed to be some ratio between the cross-sectional area of the extruded trace to the cross sectional area of the filiament. If you are extruding 10% too much material, reduce ExtrusionFactor to ExtrusionFactor/1.1.
