Hi,
My Ender was unused for a few weeks while I waited for new parts.
Now that I’ve powered it on again, everything seems to work normally (except the USB port).
As soon as I connected my Orange Pi to the USB-C port and turned it on, I smelled burnt plastic, and the printer immediately shut off.
I’ve identified the problem clearly — it’s the USB port.
A short circuit only occurs (when something is plugged into the USB-C port), even if it’s just a cable without any device.
I’ve seen photos of the mainboard, and there appear to be serial header pins, which — if I understand correctly — connect directly to the USB interface.
Can I connect directly to those pins?
What is their pinout?
I’d like to check the voltage levels there and, if possible, bypass the USB-C port and use those pins directly.
