Hi guys, I currently have a QIDI Tech X-PRO printer and it works great, however I'm looking to hook it up to octoprint. There is only one major problem, there is no serial port present on the printer, however on the earlier models there was a USB-B port on it and after doing some digging it seems there is a UART header on the control board. I do know that the pi controller has its own UART header and I was wondering if I could just wire the two together or if I could just get a UART to USB cable and connect them that way. I have included a photo of the header. Thanks for any help guys.
