Community Projects

The Duet3D community has created a wide range of DIY software and hardware add-ons to extend the capabilities of the Duet hardware and RepRapFirmware.

Here you'll find a listing (in no particular order) of the various projects with a short description and link to further information.

If you know of a project that is not on the list, but should be, post about it here.

• DuetBuddy by zapta. Uses an M5Stack to remotely monitor and display the print progress and changes colors as the duet state changes (in this case from print to pause, cancel and idle).
• Indirect bearing laser filament monitor by brunofporto. A new casing for the Duet3D Laser Filament Monitor to hold two bearings with a compliant mechanism spring to try indirect reading of filament extrusion. The sensor will read the bearing surface instead of the filament and I hope this should end the issues with different filament colors and types.
• PrintEye by EasyTarget. PrintEye is a minimalist information panel for Duet boards; it plugs into the PanelDue UART port, taking power from there and sending M408 S0 once a second, and otherwise waiting for a reply and updating the display based on their contents.
• JogBox by CJD. Connects to the PanelDue Serial port connector on the Duet 2 board and provides a rotary encoder which can be used to jog the CNC machine with the control needed. It also includes 8 buttons which, when pressed, call macros to do any user defined tasks required.
• RepPanel by seeul8er. RepPanel is a user interface for Duet based 3D printers. It is a cheaper alternative to the already available PanelDue. It uses the ESP32 and is optimized for 3.5" displays. If you source the hardware yourself it costs around 25€-30€.
• Stratadue by AJ Quick. Stratadue is an adapter board that connects a Duet 2 (Wifi/Ethernet) to a Stratasys 3D printer such as a uPrint (SE/Plus), Dimension 768 or 1200 (BST, SST, Elite) and possibly some Fortus machines.
• Laser Filament Monitor with Endstop by oseiler. A microswitch is easily added to the laser sensor pcb and the laser sensor can be turned off for filaments that the laser doesn't detect that reliably while the switch will still detect when running out of filament.
• Soft ATXvPower Control Modifications by mitch. "Two hardware modifications and included scripts to enable software control and automatic shutdown of the Duet 2 boards."
• Wireless PanelDue by AndreS. Module to make the PanelDue wireless to the Duet
• Arduino Nano based 12864 LCD controller for RRF by deathbydeltabot. "Due to the limitations of the LPC port of RRF, I wrote some software that runs on an Arduino (Mini Pro and Nano tested) to drive a RepRap Discount full graphics LCD in a similar in a similar manner as PanelDue. "
• 12864 Display ST7920 Level Shifter for D3 Mini5+ by DIY-O-Sphere. Level Shifter to allow a 12864 display to work with the mini5+

• DueUI by gtj0. DueUI is an alternate web-based user Interface for the Duet family of products. It's not meant to replace the full fledged DuetWebControl (DWC) interface but rather to complement it.
• DuetRRF-Timelapse by resam. A tool to create timelapse videos with pictures on every layer change, using a Duet controller, a Telnet connection from a Raspberry Pi (or other PC), and a webcam (to get still pictures over a URL)

• Tool Alignment Machine Vision by Danal. This script is intended to allow Duet V2 and V3 tool-changing printers to align any number of tools that have a recognizable circular nozzle via full automation. It will ultimately generate the correct G10 commands and write them to the printer in a file that can be M98 included in config.g.
• Send GCode to PanelDue Port with Checksums by Bearer. Generate valid checksums for sending gcodes over the PanelDue port.
• DuetLapse by Danal. Time Lapse camera support for Duet based 3D printers. Works with firmware V2 or V3 (including stand alone V3 or Pi based V3). Triggers images based on time, layer change, or pause.

• PrusaSlicer Tool Changer Post Processor by mkudzia. The script includes the following enhancements: Robust prime tower generation, Smart Active/Idle tool-head temperature management, PCF speed management, Validation/stripping of the GCode (i.e. Merlin M900, mapping of the fan ranges etc.)
• SMS Notifier with Image by keyz182. a script to notify on print completion. It runs on a Pi (though should run on any *nix connected to the Duet via USB), and uses Twilio to send SMS, and AWS S3 to store images.
• Cura/PrusaSlicer Script to Automatically Probe Only Printed Area by CCS86. You pass it a single parameter (mesh spacing value), and it parses the first layer gcode for min/max X and Y coordinates, and then replaces the M557 line in your start gcode.
• DuetTestSPI Tool by Danal. where SPI problems are suspected, I decide to whip together a utility that would combine all the suggested tests, give "Duet relevant" messages to be more useful to an end user, and etc.
• RepRapFirmware Configurable Printer Profile for IceSL Slicer by bot. IceSL is a pretty neat slicer that has some incredible features. It also allows total customization of GCode output with LUA scripting.

It is particularly useful when you want to same video feed to be consumed by more than one application. For example you want to use a timelapse recording recording program and at the same time monitor in real time.
• Duet Upload plug-in for CamBam by cjm. If you use CamBam to generate g-code .nc files, you might like to try a new plug-in that allows these .nc files to be uploaded directly to a Duet3D board from CamBam’s Tools menu
• gLapse by DanS79. a Python based timelapse application designed to run on a Raspberry Pi, fitted with an official camera module. It differs from most timelapse applications, in that it doesn't generate a video as its output. Instead, it stores a sequence of still images that can be downloaded and used to generate a video using a 3rd party application.
• CNC Jogger for Android by chimaeragh. Turn your Android smartphone into a CNC pendant to jog the axis around.
• RRF configuration file mirroring and management by pfn. "Downloads all files from a DWC URL under /sys and /macros to a specified directory. Creates a metadata file that remembers the DWC URL and digests of all files downloaded".

• Official Duet Plugins by Duet3D. Various plugins that come with the main DWC release.
• BTN-CMD by MintyTrebor. allows you to create simple dashboard layouts with info panels, webcams, & custom action buttons. It also has a simple status event monitoring system to alert you to machine status changes - for example you can configure BtnCmd to send a telegram msg when the printer changes to "paused" to remind you to change the filament colour mid print.
• CNC probe functionality for DWC-CNC by raymondstone. first stab at adding in the probe functions used by workbee owners that use the ooznest (ancient) version of the DUET UI. This is intended for 3.3 and above firmware versions it will not work below that.
• Filament spool load cell weight measurement plugin by resam. It contains a DCS plugin to expose an HTTP endpoint, which returns a simple weight measurement in the style of approx. 762g filament left and displays that via a DWC plugin in the top menu bar in the browser - which makes it easy to prevent out-of-filament pauses or failed prints.
