LEDs on Heater 6 on Duex5?

strips

Hi,

I have been looking at https://duet3d.com/wiki/Using_servos_and_controlling_unused_I/O_pins but not sure how to enable the LEDs wired to Heater 6 on the Duex5.

I am using an external 12V stepdown and will only be using the E6- for negative.

If I understand the wiki I should do M307 H6 A-1 C-1 D-1 to free up the pins. Then I'm lost. Probably have something to do with M280?

Thanks Jackal!

I have light on Heater 6 now

M307 H7 A-1 C-1 D-1
M42 P7 S255

Now I wonder if they run at 500Hz default? Seems ok for filming so far.
