Assuming you haven’t solved this issue or for those that come along after I’ve had this happen on a few occasions when building various printers and most recently the MPCNC.

Try dropping the Baud Rate to 115200 and see what happens. I used a cheap clone for this build and it couldn’t handle the higher baud. Once the baud rate was adjusted, I was able to continue on without issue.
