@dc42 thank you!
Is there anything else that you can think I may have to look out for?

Duet 3 6XD - Fried 3.3V Regulatorposted in Duet Hardware and wiring
Hello,
It seems that I have fried something on my Duet 3 6XD - I was switching motors and was not careful to power off the board before dis/connecting things.
My laptop cannot connect to it via USB (issue is not the cable nor port, as I can connect to my other boards) and when it powers on, only the KUSB & K5V+ LEDs turn on, the K3.3V does not.
Checked the resistance between GND and the 3.3V pins and it is ~12 Ohms, much lower than on my Duet 2s (~5 kOhms).
I tried to inspect the components on the board & found that U4 gets very hot when powered by the USB - could someone confirm this is indeed the 3.3V regulator? Having trouble confirming this.
Would also appreciate if someone could confirm the component's part number so that I can purchase a replacement.
Many thanks,
polbebe
