Problem description
When I view Comms > Machine Connection, I expect to be able to see the serial/usb port on my Pi, but instead nothing is visible in the Machine Connection dropdown.
If I connect to the controller directly from my desktop PC with LaserGrbl, it works fine.
Iāve enabled the serial interface via raspi-config (screenshot below). Iāve also run npm install serialport after seeing it in another support message.
Iām quite a n00b with Linux and the Pi world, so itās highly likely Iām missing something obvious.
Can anybody help with ways to get my Pi Zero 2 to expose the serial port which my CNC/laser machine is connected to?
System description
-
My machine is a diode laser + mill (image below)
-
I have a mystery Chinese board which accepted the grbl firmware and works find with LaserGrbl directly connected to my PC. Images below of the rig + controller board.
-
It has grbl version 1.1h installed
-
I connect via USB | Serial using ??? ā this is where I think my problem is rooted.
-
My computer(s) on which I run LaserWeb run(s) Raspberry Pi OS Lite (32-bit) Bullseye. Linux version 5.15.32-v7+.
