Powering lights with heater channel

[msbailly]

Hi All;

I'm trying to power my lights through heater channel 4. Any thoughts on how to recode the channel so it will accept binary on/off?

Use M307 to disable it as a heater, then you can control it using M42. See https://duet3d.com/wiki/Using_servos_and_controlling_unused_I/O_pins.
