Furthermore this allows for a visual test in order to verify the NeoPixels are working and sequencing correctly. Additionally it is worth enabling the NEOPIXEL_STARTUP_TEST option, this runs a Red, Green and then Blue sequence on starting up the printer. However if you set a lower amount of LED’s, they will only work up to the allotted number of NeoPixels. To demonstrate better, the below example has 25 LED’s in use on pin P1_24. Importantly remember that there is a maximum of 30 LED’s when using the DCDC V1.0 module. However the main two options we need to define are the pin used to control the NeoPixel’s, and the number of LED’s in use.įurthermore the PIN number for the NeoPixels connector on the SKR V1.4 is P1_24 and needs to be set for the NEOPIXEL_PIN option.Īdditionally the number of LED lights in use, needs to be set for the NEOPIXEL_PIXELS option. While the notes alongside each setting within Marlin will also help guide you along. Nonetheless I have broken it down with the aim of making it easier to follow along.Īdditionally from within the Configuration.h file search for and uncomment //#define NEOPIXEL_LED section by removing the two forward slashes. Without a doubt there is not much to configure within Marlin. Next comes configuring Marlin in order to run and sequence the NeoPixel LED’s. While the physical installation of the NeoPixel’s is now complete. For example 5V to 5V, Ground to Ground, and DI /DIN (Data Input) to Signal. As a result the WS2812 type of LED’s strips are perfect for this task.įurthermore each wire from the Neopixel lighting fits into its namesake on the SKR board. However as the SKR v1.4 uses a three pin connection for Neopixel’s. Moreover with NPWR jumper position enabled, the next step is to wire the Neopixel LED’s to the SKR V1.4. In addition to plugging in the DCDC power module, the NPWR jumper also needs to be enabled as shown in the below image. However, I personally would give a bit of leeway and only use 20 – 25 LED’s. Furthermore this simple plugin module allows for up to 30 5 Volt Neopixel LED’s to be powered and controlled by the SKR V1.4. Moreover the DCDC module allows more current to be safely drawn from the Neopixel connection. Without a doubt adding Neopixel lighting to the SKR V1.4 is a nice and easy task when using the optional DCDC V1.0 power module.īut what does the DCDC module actually do ?
