I have an intermittent problem. I can connect OK and have used my CNC machine many times without any issues, but recently I have been getting port disconnect issues. Not sure what is going on, but the machine can be running fine and suddenly connection is lost and the job is ruined.
I have tried changing the nano board (CH340 clone) and also tried changing the USB cable too. The cables have ferrite beads attached to stop interference. I have checked that all connections are good, and still cannot find out why this is happening.
Any help or suggestions would be appreciated.
