Remote emergency stop

Hello,

I have linuxcnc running on a CNC machine. For long milling operations I have set up a web cam so that I can see from my desk what is going on.

This is great but the next step would be to able to run an emergency stop on the machine from a remote PC (running windows for example). Both are on a local network (LAN).

I have seen that there are many ways to do remote GUI but what is the simplest way to send a stop command to a linuxcnc machine from a windows machine ?

Thanks a lot

Probably the simplest way would be to use a remote desktop viewer (VNC) to access the Linuxcnc pc, then press F1 or the e-stop button on the gui. This probably isn't the safest/most reliable way to do it but it will work.

If you have X-windows and ssh then you could have a tiny remote GUI with just a stop-button.

Try this, from the Windows machine with LinuxCNC running on the remote machine.
I haven't tested this, but I quite often use halcmd loadusr halmeter pin motion.program-line to monitor a job from my Mac.
