Ultimaker 3 RGB GCode help

Recommended Posts

Posted (edited) · Ultimaker 3 RGB GCode help

I've been looking around and there are conflicting reports of the Ultimaker 3 having a working controllable RGB led strip.

The following command does not work:

sendgcode M142 r- g- b- w-

 

I then read that this would be changed to HSV, yet this also does not work.


So what's up with the frame lighting? Is it even an RGB strip anymore? Is the GCode command simply broke?

It will depend on your hardware the UM3 did have RGB leds but due to not using them in the user experience design they may have been removed from newly produced units.

 

the code you have should work, assuming you logged in as user ultimaker to ssh on the printer in dev mode...

 sendgcode M142 r255  g0 b0 w0

should work... and show up very red...

The HSV values can be used with the API, there is a software layer translating this, via gcode it's always been RGBW though
