    Hi everyone.

    I signed up today because I'm attempting to build my own DLP printer.

    I'm trying the LCD + UV leds approach. I'm planning to use NanoDLP as the control software on a RPi3B with GRBL uploaded to an Arduino, I've sorted out everything related to electronics (circuit, motors, etc), now I have an issue with LEDs.

    I have a 100W LED matrix which can be powered on with a relay (to avoid making Arduino/Raspberry deal with high powers directly): is there a way to tell NanoDLP to power on a circuit when the print starts and power it off when the build ends either via the Raspberry or via GRBL on the Arduino? The other option would be to have an on/off switch and power on and off the light manually, but I feel this step should be automated.

    Is there a way to do it?

    Thank you!
