Yes, but is also a LinuxCNC web server. The graphical HAL plot is just an
additional capability.

Before you enter machine you need a reliale way to turn it off.
If there is a problem with software it is rather likely LinuxCNC red-estop

No, it is only wrong to rely on it.
If you are being eaten by the machine you need a had and accessble e-stop.

Mixing USB into RT kernel space is not something I would recommend due
th an MPG and a few buttons.

Agree. Something simple to check, have seen there are safety classed relays but
are not sure about the standards.

Andy posted a clear example that shows a simple way to move data from USB
to LinuxCNC.

USB should be able to handle real time but think it is complex which might be a
reason to avoid it and there are no support in Linuxcnc. There are however a
lot of cheap development boards available which may make it a very cheap and
good choice. There are standard protocol for keyboard and mous
I have actually been wondering about the same/similar thing, on how to

think the technical how to do it is clear now. The bigger problem is the

Thanks. The example is clear. All that is needed s a user-space app that
can talk to a user any way it wants. Seems the details are all abstracted
away in hal.component
I can think of a bunch of maybe useful experiments to try.

I'd like to build a handheld pendant controller. I have some ideas about
