The laser does not appear to be considered connected

‘The laser does not appear to be connected to your computer.’

It’s a laser script 6040 Ruida connected by USB to a Mac.

Device was set up manually.

Have tried the USB in each port on Mac. Also tried changing port selection from auto.

Still: the laser does not appear to be connected to your computer.
Make sure it is plugged in and any required drivers are installed.

Ruida uses an FTDI device for the serial/USB connection, and the serial port driver that Apple ships with macOS interferes with the FTDI driver. You can watch how to fix the USB / Mac port thing here:

You can also connect via Ethernet, (a little more involved, but not a huge setup effort) which is very solid and does not have these issues.
