I connected without using Panel

Hi Dear

Thanks for your feedback verymuch

I used a serial monitor to verify that Arduino sent a message
The good news is I found the problem
Bad message is that the serial monitor cannot accept any message sent by Arduino
I use an Arduino micro pro clone, using AVR_ATmega32U4 processors
So I downloaded the Arduino code from the tutorial and burned it directly into Arduino. What should I change?

@jay_s_uk

I send M122 P200 the DWC give me these feedback:

serial.aux.rxTxPins = {A.10, A.9}
tx1,btnenc = A.9
rx1,lcdrs = A.10

This is the TX RX pin information I think is relevant.
I use PA10 as the serial port receiving terminal to connect with Arduino TX0

Dear droftarts

Thank you very much for your reply
I organized the wiring and connected the wires strictly according to the course.
RX pin has been wired to VCC
The problem remains unresolved
I found some problems with the program changes you mentioned
In the（ RotaryEncoder. h ）file, line 5（ # include<Encoder. h>）prompts that there was no file during compilation (I'm not very good at Arduino)
So my program didn't change
If the communication between CDY mainboard and Arduino goes wrong, I won't react when I press the emergency stop button, right? But in fact, the emergency stop button will cause the CDY mainboard to restart.Does this mean that there is no problem communicating Arduino with CDY mainboard?
I use the FLY CDY V3 mainboard to communicate with Arduino

Dear everyone

I created Pendant as directed by the DUET3D official website, but now there are some strange problems.

1.When the arduino micro pro is brushed and the pulse is sent through the knob, the LED at the sending end of arduino does not flash, and the LED indicator of RX TX is always on. I'm not sure if it is normal.

2.I use the FLY CDY mainboard and connect to the TX0 pin of Arduino via the RX pin of the mainboard. Because I do not use Panel, I only connect 5V COM and TX0.

3.This problem makes me unable to judge whether Arduino communicates with CDY, but after I press the emergency stop button, the mainboard will restart, but any other function will not work.

If any friends can help me solve this problem, I would like to thank you very much and look forward to your reply.
