“Busy/Paused” Machine Prompt — Nano Troubleshooting

If the machine shows a “Busy/Paused” message, first check whether there is a process currently running in the APP, such as framing or engraving. If so, pause that process.

If no process is running, there are two possible solutions:

1. Check Driver Installation:

Ensure the installed driver matches your operating system.

If the driver is incorrect, the machine may show “Busy/Paused.”

Reinstall the correct driver.

2. Confirm USB Connection to Nano Pro:

Make sure the machine is successfully connected via USB.

Select the correct COM port (check Device Manager → Ports for the one with CH340 driver).

Ensure the port is not occupied by other software.

Once connected successfully, the console should display board information.
