Getting started using Cura slizer with Duet3D

By BeTrue3D

The slizer Ultimaker Cura from Ultimaker is one of the most popular and most advanced free slizers on the market, but with everything else there is a learning curve, and since there is no real standard for how these things work the initial setup might prove a challenge.

This post is about getting started using Ultimaker Cura with your Duet3D controller.

It’s not going to be a comprehensive post about using Cura, but a short to the point post to get the inital crucial basics in place.


  1. Add Printer
  2. Machine Settings – Printer
  3. Machine Settings – Extruder1
  4. Print Settings

1) Add Printer

When adding a new machien, you shouldn’t pick your machine model, as that profile will be geared towards your old electronics. Instead we weill create a Custom Printer.

  • Custom – Custom FFF Printer
  • Pick a suitable name for your machine
  • Hit Add

2) Machine Settings – Printer

  1. The crucial part here is to pick RepRap as G-code flavor.
    • You most likely need to change Printer Settings to match your machine, and maybe modify the Start G-code and End G-code.
    • You can always do these things later.
  2. Once done click on the Extruder1 tab.

3) Machine Settings – Extruder 1

  1. Change Compatible material diameter to match the diameter of your filament.
  2. Hit Next to return to the main window

4) Print Settings

  1. Click the small pencil in the upper right corner.
  2. Click Custom >
  1. When moving the mouse over one of the different fold out menus a small gear will appear. Click one of these.
  1. Start typing relative in the Filter… box
  2. In the Special Modes section: put a mark next to Relative Extrusion.
  3. Click Close.
  1. Special Modes section is now shown. Click the arrow at the end to open it.
  2. Put a mark in Relative Extrusion as Duet3D firmare uses this as default.
