So I'm asking: Can a similar web based interface be added to linuxcnc?
I have used it in that fashion (as a PLC rather than CNC control), on a
headless server running Debian 12, I run:
linuxcnc (start the hal loader script with systemd at boot, including
some Beckhoff ethercat I/O) A python hal to mqtt bridge connects the gui
to hal
mosquitto to pull in data from remote sensors
influxdb to do the datalogging
Node-red provides the gui and the non-real-time logic. Here is where the
fun begins. Sorry, I don't know much about coding java. Between
point-and-click programming and asking llm for custom java functions it
went together quite well.
All you need on the remote HMI display units is a web browser to display
node-red gui.
On another system I did a similar setup except the server is a Beckhoff
CX5020 and all the sensors are connected to Beckhoff ethercat remote
I/O. The CX5020 was a bit special to get started with. If I remember
right, it didn't seem to have enough RAM to complete the installer
successfully, also I think it needed to run 32 bit. I just installed the
OS on another pc then cloned that to the 8GB CF card and the CX5020
booted that.
It really made my day when I discovered linuxcnc supports ethercat.
