Duet 3 Expansion 3HC Temp Sensor Oddness

I'm new here (I hope this is the right place for this post) just thought I would share... This is not a bug report just my odd experience getting a Duet 3 Expansion 3HC board heaters working.
The boards booted up nicely and I was able to connect via DWC. Ran a few tests, motors, endstops. etc... but when I got to Heaters they reported "Offline" but the senors reported room temps. After few hours of tweaking configs and wire changes and I was able to track down the problem.
Turns out that the temp sensors must wired to the 3HC and not the main Duet. Then it worked fine.
Or maybe I'm just not doing something, that is total possible. 0_o
See https://duet3d.dozuki.com/Wiki/Duet_3_firmware_configuration_limitations for the current firmware limitations.

@dc42 Also, but not on that list, is that tuning of heaters connected to expansion boards is not yet supported.
