Configuring Multiple Extruders - Emmanuel Katto Uganda
-
Hi all, I am Emmanuel Katto. I’m working on a project that requires multiple extruders, and I'm using a Duet 3 board. While I’ve followed the basic setup instructions, I’m finding some areas confusing.
- Can someone provide a step-by-step guide on configuring the extruder settings in the firmware?
- Are there specific parameters in the config.g file that I should focus on for dual or multi-extrusion setups?
- How do you manage retraction settings for multiple filaments, and do you have any tips for minimizing oozing issues?
I appreciate any guidance you can provide!
Thank you!

@emmanuelkatto The configtool lets you set up multiple extruders that can be mapped to different tools. Once you make changes, you can see the corresponding configuration M-codes in the Preview panel.
If you have a tool changer or two independent nozzles, you'll need two tools for your setup where, for example, tool #0 is mapped to extruder #0 and tool #1 is mapped to tool #1. You can configure this in the configtool as well. See also https://docs.duet3d.com/en/User_manual/Tuning/Tool_changing if you need to set up sequences to activate/park the tools when needed (if you have a tool changer).
Regarding firmware retraction, see M207: https://docs.duet3d.com/en/User_manual/Reference/Gcodes
