Frequently Asked Questions about the D3D Universal 3D Printer

How do you make sure you have proper extrusions? (3 items)

1. Make sure filament diameter is set correctly in Cura. 2. Make sure the nozzle diameter in Cura matches the physical nozzle. 3. Make sure the stepping (steps / mm) is set correctly. M92 command in startup code in Cura configuration.

What is difference between gcode and the stl file? STL is the generated geometry file for Cura. It can be generated by FreeCAD, Inkscape or other programs. gcode is the motion code for the 3D printer.

• My nozzle is oozing, what is wrong? My printer is leaving strings over empty space, what is wrong?

Retraction or too high temperature.

• Filament size

• What do I need to set in Cura?

Basic

What is the max / min layer height?

0.96 is the maximum layer height for a 1.2 nozzle. The minimum would be approximately 0.2, but thinner layers becomes impractical, as it increases print time.

What is the max / min shell thickness?

1.9 max, as the movement is slow 0.6 min to maintain shell integrity

What is retraction? When the printer retracts the filament into the print head. This prevents leaving strings over gaps. Retraction is enabled in Cura under Basic Quality. Beside the checkbox is 3 dots for expert configuration.

What is fill? The ability to control the fill of an object. 0 = hollow object, 100% is completely solid object.
