This article will help users add additional extruders to Cura (v2 & 3) in order to slice for Palette+. Note: This article is geared towards advanced users, as the process of adding extruders in Cura can be extensive. However, these steps would only need to be completed once.
- If you already have a printer profile in Cura, open this profile's machine settings (Settings > Printer > Manage Printers > Machine Settings). Copy your Start and End GCode to a document for later use.
- Add a new printer (Settings > Printer > Add Printer).
- Add a Custom FDM printer even if your printer is on the list. Even if you have an existing printer profile, there is currently no way to copy a machine and add extruders in Cura.
- Fill in your printer's information, including dimensions and settings. Set the number of extruders to 4 and the diameter to 1.75 mm.
- Under the Extruder tab for each extruder, enter your nozzle diameter and ensure that the other fields are empty or 0. Click Finish to return to the home screen.
- Go to Settings > Extruder 1 > Materials > Manage Materials. On this screen, select the material you would like to print with (ex. PLA) and create a Duplicate. Under the Information tab, update the name and assign different colors. This will help distinguish between extruders and profiles.
Under the Print Settings tab, set the Standby Temperature to be the same as the Default Printing Temperature. Repeat this steps for 4 different profiles (one for each extruder). Once updated, click Close to return to the home screen.
- At the top of the right banner, you can assign each material profile to an extruder.
- Below, under Printer Setup, select Custom, which will expand a menu allowing you to change the profile settings. If you hover over a category, you'll see a gear symbol which will further expand the menu of customizable settings. Ensure that Standby Temperature and Nozzle Switch Retraction Distance are selected.
- Back under the Material category, set the Printing Temperature and the Standby Temperature to be equal and set the Nozzle Switch Retraction Distance to 0. Repeat this for all 4 material profiles.
- Now you're set to slice! When you load multiple STL files, you can assign an extruder for each file which will color-coordinate with the material profile. Once all files are loaded and assigned, select all parts by holding the "Shift" key and clicking each part of the model, then right-click and select "Merge Models". Please ensure that all pieces are loaded before merging, as you are unable to assign extruders once the model is merged.
