I can work on second UART port, thanks. I have another question. I want to send UART command (G code or M code) to the second UART port. Does the second UART port get all G code and M code that like as USB port?

Can't use BOSSA to update and fix Duet3 board
I make new bin file and update the firmware failure. I download Duet3Firmware_MB6HC.bin and want to use the BOSSA to update. I have erased the Duet3 board. But I can't find the COM port with USB port. How do I fix my Duet3 board?
RE: M915 stall detection problems with sensorless homing
@dc42 I can do stall detection when I use native x16 microstepping in M350. Thanks.
M915 stall detection problems with sensorless homing
I have a Duet3 MB and my firmware is MB6HC 3.1.1. I am configuring the X axis to test sensorless homing.
If I set M915 X S2 R0 F0 H200, it appear the motor turn clockwise then it stop. I think it present the motor happen stall detection.
If I set M915 X S3 R0 F0 H200, it appear the motor turn counterclockwise continuously. I think it present no happen stall detection. I try to stop motor but no response.

The Duet Expansion Breakout Board is for Duet3 MB 6HC
Duet3 MB 6HC can't output control signals for the stepper motor, like as EN, STEP, and DIR. In the future, Duet3 MB 6HC can use CAN bus to control the expansion board and output 6 sets of EN, STEP, and DIR (X, Y, Z, U, V, W) signal at least.
RE: How to build the bin file?
@dc42 I paste the crc32appender.exe on my path.
I fixed all problems. Thank you, but I have the last question.
Is the bin file for main board if I select build configuration -> Set Active -> Duet3_V06?
Is the bin file for expansion board if I select build configuration -> Set Active -> Duet3_V06_CAN0 ?
