I’ve had my Nomad883 in the same configuration for months. Now, in the past week, I’ve started getting
GRBL Error: Serial Port: Unknown Error
GRBL Error: device Not Found
Current attempts to correct the problem are:
Make sure all USB connections are clean and contacting well.
Make sure there are no other power cords near the USB cord.
Restarted the controlling computer to make sure the USB ports are detecting properly.
I will be running with the above to see if the problem pops up again.
Also note: I have a second Nomad883 right next to the first, and it has not stopped at all. The USB cord is routed the same way as my older Nomad. I suspect something is going wrong with my older Nomad, or the computer I am using to run it.
I will update as things progress.
