      do you still need an arduino? or can I just connect the signal wire on the strip to pin 5 of CONN_LCD which happens to be EN-10 pin of stepper 10 driver using a 74HCT08 and then use M150 command to control? can i still use pin 5 if I have a stepper driver connected to stepper 11 (pins 4,6,8,10).

        @tekstyle if you don't have stepper driver 11 connected then you don't need an Arduino, just a fast level shifter (e.g. 74HCT08) to boost the signal to 5V. A limitation is that on the Duet WiFi/Ethernet, using the M150 command to change the lighting will pause movement briefly. This is because there is no dedicated DMA-controlled SPI channel for LED lighting on the Duet WiFi, so the firmware has to disable interrupts while it sends the data to the LED strip.

            @tekstyle that's the only sketch I know of

            Owns various duet boards and is the main wiki maintainer for the Teamgloomy LPC/STM32 port of RRF. Assume I'm running whatever the latest beta/stable build is
