One of the issues I had with Cura was the printing of the lines did not have good adhesion for filament lines which laid side by side. These are the changes which I made to enhance the side to side adhesion: In the Quality section of a profile: Line Width: changed from the default of 0.4 to 0.42 In the Material section of a profile: Printing Temperature: changed from the default to default + 3 degrees ... Example: 195 became 198 Flow: changed from the default of 100% to 110% In the Travel section of a profile: Z Hop Height: changed from the default of 0.075 to 0.15 In the Cooling section of a profile: Regular Fan Speed at Layer: changed from the default of 4 to 8 One other "gotcha" for Cura: If you resize a model which is too large for the print bed ( X and Y dimensions resized, but not the Z ), the model can end up with a negative Z setting. Cura will slice the model, but you will lose any portion of the model which is below the print bed. So, a 10 mm Z size model with a -3 mm Z setting will result in a 7 mm high model being printed! The solution is to check the model with the Move function after a resize operation.
