MacOs-No supported firmware detected

Hello,

I installed LaserWeb on a Mac OS High Sierra 10.13.6
I have a laser printer with a Cronos GRBL V1.0 2-axis card plugged into the USB port.
I always get the following message:
Connecting Machine @ USB,/dev/tty/.Bluerooth-Incoming-Port, 115200baud (Other ports do not work)
Machine connected

_ No supported firmware detected. Closing port /dev/tty/.Bluerooth-Incoming-Port
Machine connected

Can you help me?
Thanks a lot

Hi @Carlu

It looks like laserweb is simply finding that a Bluetooth port on your machine looks like a serial port; so it tries to connect using that but since it is not the printers USB port it then fails.

You need to enter the correct port and speed in the connection dialoug; it will attempt to detect possible ports for you but this can go wrong.

Have you been able to connect with any other CNC/Laser Control Software? If so; what settings worked for that (what port and speed did you specify in that software)?

I’m not a MAC expert; but am a bsd/unix guy so I can probably debug but please be aware that I dont have hardware to test on or do screenshots :frowning:

Hi !
On my Mac, the only port that responds is the USB, /dev/tty/.Bluerooth-Incoming-Port, the others are not accepted.
So I think I’ll find a easier solution, maybe based on Arduino…
Thank you very much for answer and the time spent. It was very nice of you.
Kind regards

seems to be a common problem on Mac, have you seen this which provides a possible solution? OS X and Connecting to an GRBL board - Getting Started With LightBurn - LightBurn Software Forum
