Controlling LEDs with duet 2 wifi
-
Hello, Im trying to wire up LEDs, and I would like to do it without the expansion board. I know that you can control LEDs with unused heater or fan outputs, but is there a way to remap some of the pins on the unused connector to become i/o signal wires to mosfet LEDs to drive them? There are 50 unused pins if you don’t have the expansion board, so my goal would be to remap a selected few to become signal wires. They don’t have to be pwm pins, just i/o. Is this possible?

Which pins would you like to use? One of the heater pins on the expansion port would be a good choice.
What kind of signal does your LED mosfet require?
How you configure it would depend on which firmware version you are using. In RRF3 it's as easy as defining the desired pin with a M950 command as a fan, and then using a M106 command to control that fan output.
