UM3 RGB LED Functionality?

Recommended Posts

Posted · UM3 RGB LED Functionality?

I saw a video from 2017 detailing the insertion of the M142 instruction into a G-code file to modify the Ultimaker 3 LED strips to any wanted RGBW colour. This seems to have been disabled since then. The RepRap wiki states that M150 should work for Marlin flavour (which I think the UM3 uses) but it doesn't seem to. 


I'm using a Cura-generated G-code file as boilerplate and the rest of the instructions are executed, just not the M142/150 instructions. 


Any ideas?

    M142 gcode still works for me like mentioned in this post:




    note that the parameters are in lowercase (which is quite unusual for gcode)


    ...but it is well possible that devices with newer manufacturing dates are not equipped with rgb led-stripes anymore? 🤷‍♂️


    You can try to use the (official) API - the documentation is reachable from the printers home-page.

      • S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
        (Sorry, was out of office when this released)

        This update is for...
        All UltiMaker S series  
        New features
        Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.

      • Ultimaker Cura 5.6 stable released
        Cura now supports Method series printers!
        A year after the merger of Ultimaker and MakerBotQQ, we have unlocked the ability for users of our Method series printers to slice files using UltiMaker Cura. As of this release, users can find profiles for our Method and Method XL printers, as well as material profiles for ABS-R, ABS-CF, and RapidRinse. Meaning it’s now possible to use either Cura or the existing cloud-slicing software CloudPrint when printing with these printers or materials
