What you will need #
- The EZNeo Strip
5V Rail Warning – The SKR 1.4/1.4T boards say they support a 3A output from their onboard voltage regulator. They are also known to be unstable on some boards. If you have issues with the EZNeos flickering you can bypass their onboard regulator and use our separate 5V power module and then only use the IO pin on the NeoPixel header (this is the center pin).
Plug it in! #
The SKR 1.4/1.4T boards have a dedicated NeoPixel header. This pin is pre-setup in Marlin 2.0 and uses pin P1_24.
Just simply plug in the EZNeo cable to the NeoPixel header on the board as shown below and the other end of the cable into the EZNeo strip.
Make sure the NPWR jumper is in the “lower” position as shown in the picture below.
Firmware Setup #
Pin Number #
The SKR 1.4 and 1.4T use pin P1_24 for their NEOPIXEL_PIN when using the header plug as shown above. TH3D does not provide firmware for the SKR 1.4/1.4T boards, refer to BTT official firmware or Marlin for firmware for those boards.
Vanilla Marlin Setup #
If you are using a standard build of Marlin (aka “Vanilla” Marlin), follow the directions below to set the correct options to use the strips with your Marlin build. These directions are based on Marlin 22.214.171.124. Older/newer versions of Marlin may have different values than shown below.
Configuration.h Settings #
In Configuration.h make the following changes:
- Uncomment the NEOPIXEL_LED line
- Set the NEOPIXEL_TYPE to NEO_GRB
- Set the NEOPIXEL_PIN line to whatever IO pin you are using to control the strip.
- Change the NEOPIXEL_PIXELS value to 15
- Uncomment the NEOPIXEL_STARTUP_TEST line
Configuration_adv.h Settings #
In Configuration_adv.h make the following changes:
- Uncomment the LED_CONTROL_MENU line
These settings will enable all the Marlin RGB LED control options. You can change the LED colors from your printer LCD menu or through Gcode commands (M150)
