@alankilian So my unit isn't faulty and I have to find another way to toggle my relay. Thanks a lot

Hi guys,

I just received my Duet 3 Mini 5+ and plugged it into my PC to to configure it before it goes into the printer.

I'm planning to control a relay to turn off the printer's PSU after a print is done. While planning out my connectors I noticed that 5V_EXT_IN did give me 0V (which is expected) so I set the jumper on 5V_SEL and 5V_EXT_IN. Now I'm getting 0.85V when measuring 5V_EXT_IN to GND. On the other hand, 5V_EXT gives me a perfect 5V.

Is my unit faulty or is this expected behavior?
