M591 BTT debug output?

[paralepsis]

Hi,

I'd like to see how the output of my BTT smart filament sensor matches with what the printer thinks ought to be happening. I'm using:
M591 D0 P7 C"io6.in" L7 R50:150 E22 S1

I'm not getting errors, so presumably it's working (?). I bet this is an easy M111 or something, but I can't find the magic.

Thanks!
