Hello,
I am using a Duet 6HC to control a custom 3D-printer.
I am trying to control a pressure controller, which requires 5V signals. I would like to use the 5V_ext pin from one of the IOs. However, measuring it (5V_ext to GND) shows OL. The 12V derived internal 5V seems to working (red status light).
Now, I am wondering if the 5V_ext pin only supplies 5V if an external 5V power supply is connected?
Thanks in advance!
Best, Felix
