@amjm22 When opening your config.g in a browser, it is an unreadable string. In the forum editor, you can use the "</>" tag to create a box to which you then can paste the config like this:

The error message hints at some wrong port assignment with M950, in this case, I think you assign IO_1 twice:

M950 E0 C"io1.out" T1 ; configure LED strip #0

M950 H1 C"out1" T1                                    ; create nozzle heater output on out2 and map it to sensor 1

BTW, in both cases, the comment is misleading, it doesn't match the effective IO-ports

@amjm22 M950 with E parameter to support LED strips is only available in firmware 3.5.

@amjm22 In RRF 3.4.6, you can only connect LEDs to the 4-pin connector labelled DS_LED. Configure with M150. See this page for details: https://docs.duet3d.com/en/User_manual/Connecting_hardware/IO_Neopixel_DotStar
