The USB port on the front of the X-Plus printer can read only so it can not be used to connect the Raspberry Pi. However, hope is not lost! There is a way to connect directly to the motherboard using a TTL serial USB cable.
How to connect the TTL cable to the Qidi motherboard:
Green cable goes to Rx pin
White cable goes to Tx pin
Black cable goes to Gnd pin
