under voltage warnings
-
Ive recently been getting under voltage warnings when shutting off 24v power via relay and leaving 5 v on using pson pin. the 5v side is on a going into board at pson 3 pin header via a buck converter powered by the same powersupply as 24v side. its been wired like this for 3 years this is new behavior with 3.5.1. the 5v buck has its own direct wires to the psu.
its a 2017 vintage duet 2 ethernet.

@Miss-Rebekah If you are shutting off the VIN supply then the undervoltage warning is to be expected. I cant remember which firmware version that introduced the warnings.
