@Duet_Science_Application said in Getting metadata commands to loop at different rates:

one loop designed to run at half a second, the other ideally over a full second.

Why not have a single loop that runs every half second, and within that have an if-command that executes its body on alternate iterations?

@dc42 I see! That fixed all of my issues, thank you.

@Duet_Science_Application said in `Duet 6HC Output 3 output always on:

Thanks again for getting back to me. I tried your solution of switching to different Q values, but the output is still the same at 24V AC. I probed the black component located next to the pins (assuming that this was the protective diode that possibly is failing) and noted that it is allowing the same current in both directions, while the other two components for the pins next to it allow current preferentially in one direction. This leads me to suspect a component failure over coding issues.

That diode should not be open in both directions so it is possible you fried it but I don't see how that happened from your description. (BTW its not the VIN fuse, if that had blown you would not have 24V). just changing the PWM frequency should not have damaged anything.

I assume you probed the diode with the board unpowered?

Just t check something try setting the Q parameter back to the old setting.
