For the power supply, we recommend a stable 24V 2A power supply, which you can find on platforms like Amazon and AliExpress.

As for the LED strips, you can purchase any RGBW/RGBWW or RGBCCT 24V LED strip. Make sure they aren't high-density to avoid overloading the power supply or MOSFETs.

This option, when enabled, bypasses the finish and error indicators and simply cycles the LED strip through red, green, and blue colors.

Yes the blled controller will work if you have a ams connected to your printer.
