Can the OPI5 be Configured to Run LCNC?

Found the port for the RS-485 converter.
demsg | grep tty
Plug it in and run the command again. And extra /dev/ttyACM0 was reported at the bottom.

Great you've got the Boss3 running!
I would think that it has to be possible to use the RS-485 of the Mesa 7i96:

My USB adapter was taken over by BRLTTY, you could see it in dmesg. To disable that:
sudo systemctl stop brltty-udev.service
sudo systemctl mask brltty-udev.service
sudo systemctl stop brltty.service
sudo systemctl disable brltty.service

Instead of /dev/ttyUSBx it's better to use /dev/serial/by-id/id-of-your-adapter so when you've another serial device connected it won't randomly change the order ttyUSB0 to ttyUSB1

Or you can just do
sudo apt purge brltty
and be done with it.
Took me a while to get there about 2 years ago, now i just remove it with all the stuff that i do not need as soon as installation finishes.

Removing brltty

Does anyone have a package for vfdmod that would be appropriate for Armbian? The deb package on Github appears to be for the wrong architecture.

EDIT:  Went with mb2hal instead.  So far, I've been able to turn the spindle on.  Could not get it to turn off, but at least I know it is communicating.

In case you still would like to try vfdmod...

A ferrite bead corrected my communication problems, and I'm now able to control the spindle by setting registers using mb2hal.

But, I think I still want to give vfdmod a a run. Which directory should the file above go in?
